Circular knitting machine
Technical Field
The invention relates to the field of single-side circular knitting machines, in particular to a knitting mechanism of a single-side circular knitting machine.
Technical Field
Circular knitting machines, known as circular weft knitting machines (or circular knitting machines). The circular knitting machine has the advantages of high loop forming system (called yarn feeding path number or loop forming path number in enterprises for short) quantity, high rotating speed, high yield, fast pattern change, good fabric quality, few working procedures and strong product adaptability, so the circular knitting machine is developed quickly.
Circular knitting machines generally fall into two broad categories, single-sided and double-sided.
Generally, a circular knitting machine is mainly composed of a yarn supply mechanism, a knitting mechanism, a drawing and winding mechanism, a transmission mechanism, a lubricating and cleaning mechanism, an electric control mechanism, a frame part and other auxiliary devices.
The knitting mechanism is the heart of a circular knitting machine and mainly comprises a needle cylinder, a knitting needle, a cam, a triangular seat (including the cam and the triangular seat of the knitting needle and a sinker), a sinker (commonly known as a sinc sinker and a sinker), and the like.
Referring to fig. 1 to 3, the working principle of the conventional single-sided circular knitting machine is as follows: the plurality of sinkers 2 and the knitting needles 3 are placed in the grooves of the needle cylinder 1 and do circular motion along with the needle cylinder 1, the sinkers 2 continuously do reciprocating motion in the horizontal direction through the tracks of the plurality of sinker water chestnuts 4 and the knitting needle water chestnuts 9, and the knitting needles 3 do up-and-down motion, so that the knitting process is completed. The structure of the existing single-sided circular knitting machine is shown in figure two: the sinker 2 and the knitting needle 3 are placed in the groove of the needle cylinder 1, the sinker diamond 4 is locked on the sinker disc 6 through a first screw 8, and the sinker disc 6 is divided into a plurality of equal parts to be fixed on a sinker ring 7 through a second screw 5 for the convenience of cleaning a machine table. As the in-and-out of the sinker diamond 4 is often adjusted to drive the in-and-out of the sinker 2 to achieve the required process in the assembling process and the production of various cloth covers, the sinker diamond 4 is beaten by hands after the first screw 8 is loosened to obtain the required position in the adjustment process, and the mode obviously has poor control precision and large workload, and a plurality of components are matched, so that the precision is not well controlled.
Because the round-bottomed knitting machine often needs to adjust the business turn over of sinker water chestnut when assembling the in-process and producing various cloth covers, consider that the current structure is not well adjusted and the precision is not well controlled after the adjustment, consequently change the precision and the work efficiency that the structure of prior art is favorable to improving the board.

the first spacing subassembly includes:
the limiting pin is fixed on the base and is in sliding connection with a limiting groove formed in the lower side of the water chestnut, and the limiting groove extends along the radial direction;
the guide screw penetrates into the limiting groove from the inner side of the water chestnut along the radial direction and abuts against the limiting pin; the guide screws are matched with the water caltrops through thread structures and can rotate relative to the water caltrops;

In another embodiment, the present invention may also adopt the following scheme:
a circular knitting machine has an annular base and a plurality of diamonds for receiving sinkers; the water chestnut processing device comprises a base, a plurality of water chestnuts and a plurality of installation mechanisms, wherein the water chestnuts are adjacently arranged on the base along the circumferential direction, and each water chestnut is installed on the base through the installation mechanism.
The mounting mechanism includes: the first limiting assembly is used for limiting the water chestnut to move outwards along the radial direction relative to the base, and the second limiting assembly is used for limiting the water chestnut to move inwards along the radial direction relative to the base and move upwards along the axial direction relative to the base.
Wherein, first spacing subassembly contains:
the limiting pin is fixed on the base and is in sliding connection with a limiting groove formed in the lower side of the water chestnut, and the limiting groove extends along the radial direction;
the guide screw penetrates into the limiting groove from the inner side of the water chestnut along the radial direction and abuts against the limiting pin; the guide screw is matched with the water caltrop through a thread structure and can rotate relative to the water caltrop.
The second spacing subassembly includes:
the screw rod part of the limiting screw penetrates through the through hole formed in the water chestnut and penetrates into the base in a manner of inclining from outside to inside in a relative radial direction, a preset gap is formed between the periphery of the screw rod part of the limiting screw and the inner wall of the through hole, and the screw rod part of the limiting screw is matched with the base through a thread structure; the nut part of the limiting screw is abutted against the water chestnut; the water chestnut is provided with an accommodating groove corresponding to the nut part, and the nut part of the limiting screw is provided with an inner hexagonal groove.
The limiting screw can be screwed out of the base so that the guide screw and the water chestnut can integrally move inwards along the radial direction relative to the limiting pin, and the limiting screw screwed out of the base can be screwed into the base after the guide screw and the water chestnut integrally move inwards along the radial direction relative to the limiting pin so as to push the guide screw and the water chestnut integrally move outwards along the radial direction relative to the limiting pin.
The above scheme can be obtained according to the simple deformation of the water chestnut structure and the base of the first embodiment, so that the mounting directions of the guide screw and the limit screw are opposite, but the function of the mechanism for integrally adjusting the water chestnut is the same. Since the above-mentioned solution is a simple modification of the first embodiment, a person skilled in the art can know how to modify it according to the drawings disclosed in the present invention, and therefore, the drawings of the solution are not given.
Preferably, there are at least one pair of the guide screws 10, and the at least one pair of the guide screws 10 are symmetrically arranged at two sides of the limit screw 11. It should be noted that the guide screws 10 are usually a pair, but those skilled in the art can correspondingly adopt more pairs according to the size and model of the machine platform and the adaptability modification of the water caltrops.
Further, in the two schemes, the base 15 includes a sinker ring portion and a sinker ring portion, and the limit pin 13 is fixedly installed in a corresponding slot hole (i.e., the limit slot 14) formed in the sinker ring portion; the sinker ring part and the sinker disc part are designed integrally. Because the functions of the sinker ring and the sinker disc are integrated together, the integrated design of the sinker ring part and the sinker disc part is formed, the sinker ring is reduced, the structure is simpler, and the machine cost is reduced.
Referring to fig. 2, 3, and 7-10, the working principle of the present invention is as follows:
according to the existing scheme, the radial movement of the sinker diamond is controlled by knocking by hands, as shown in fig. 8, the sinker diamond 4 of the traditional rounding machine is matched with a first screw 8 (the mechanism structure of the traditional rounding machine is shown in fig. 2 and 3), when the sinker diamond 4 is adjusted, the first screw 8 needs to be loosened, then the sinker diamond 4 is knocked by hands to move in a shown slotted hole until the required position is reached, and then the first screw 8 is screwed again. And the first screw 8 is positioned below the water chestnut 4 of the sinker, so that the operation is difficult, the tightness degree is inconvenient to control, and the precision is also difficult to control.
The invention controls and adjusts the rotation quantity of the guide screw, the rotation turns of the screw are visual and controllable, and the precision is better grasped. As shown in fig. 9 to 10, when the limit screw is ensured to fix the sinker diamond corners, a movement margin is also provided (as shown in a partially enlarged view of fig. 10, the limit screw and the new sinker diamond corners have a certain adjustment gap), and the limit screw can move in cooperation with the sinker diamond corners. The limit screw can push the water chestnut when being locked, and the stroke of the pushing amount is determined by adjusting at least one pair of guide screws symmetrically distributed on two sides of the limit screw. Specifically, see fig. 9, which shows a bottom view of the new sinker diamond, it can be seen that the stop pin is fixed to the stop groove, the guide screw can move relatively to the stop pin in the stop groove, and drives the new sinker diamond to move, the specific moving stroke is determined by the at least one pair of guide screws, and then the diamond is moved and fixed at the required position within the moving stroke range by tightening the stop screw.
The whole set of adjusting system provided by the invention can accurately adjust the inlet and outlet of each sinker diamond, is simple to adjust and operate, and does not need to knock the sinker diamond. And the limiting screw and the guide screw which need to be adjusted are positioned on the front side, so that the operation is convenient for a user, and the control precision is also convenient. The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
