Description

The tension force of braiding machine spindle is controlled and brake gear

Technical field

The present invention relates to the braiding machine technical field, refer to that specifically the tension force of braiding machine spindle is controlled and brake gear.

Background technology

High-pressure oil-transporting hose, air hose, cable flexible pipe etc. even comprise the delivery hose that bathroom is used, and all need at the outer braid protective layer, be wound in net with braided wires such as wire or nylon yarns.The general structure of China's braiding machine is all to have more than 20 spindle walking S shape track round the flexible pipe of central authorities on panel; in traveling process, braided wires is wound on the flexible pipe of central authorities; weaving require spindle continuously, permanent tension force ground supplies braided wires; if the silk of one of them spindle is finished or is disconnected; entire machine all can be shut down by auto-breaking; after the operative employee is disposed, continue the start braiding, the frequency of shutting down in as seen braiding process is still higher.When outage shutdown suddenly; all have the spindle of silk all can continue rotation under effect of inertia to supply outward silk; and the braiding process is suspended; the thread tension of unnecessary supply disappears; even can be entangled with agglomerating more than the silk thread that the spindle that inertia is good throws away; the quality of impact start braiding next time, the emersion wave striated structure is lax.Weaving requires spindle at once to brake when shutting down, and the inertia wire vent is more short better, and before and after wishing to shut down, the tension fluctuation of braided wires is the smaller the better.Existing braiding machine is still far from perfect in this respect, and the spindle brake mechanism of the prior art shown in Figure of description 1 for example is the frictional force braking spindle chassis of top fork rear end, and the brake stroke is large, reaction is insensitive, and effect is undesirable.The inventor is engaged in the braiding machine manufacturing for many years, through practice accumulation and research and development diligently, has finally solved this problem, and this case occurs thus.

Summary of the invention

The object of the present invention is to provide that brake is sensitive, tension force braiding machine spindle that can control braided wires tension force in the braiding process and before and after shutting down is controlled and brake gear.

To achieve these goals, technical scheme of the present invention is as follows:

The tension force of braiding machine spindle is controlled and brake gear comprises: upper pendulum bar, draft link, ratchet, stage clip, spindle shelf;

Described upper pendulum bar and draft link bearing pin are connected on spindle shelf, have fixed the wire vent thread guide in the middle of spindle shelf, and the wire drawing thread guide has been fixed on the spindle shelf top;

The ratchet bearing pin is connected on spindle shelf, and the chassis of ratchet and spindle is flexibly connected by bayonet socket, can rotate together along with spindle;

Stage clip be arranged on the concentric spindle shelf hollow pipe of spindle in, the stage clip upper end holds out against spindle shelf, the lower end is pressed on by press spring base on the reed pipe pin of draft link, draft link front end depress.

Described draft link is all parts of bifurcated of front and back end, and is porose on two bifurcateds of rear end, links together with the spindle shelf bearing pin, and front end can be able to swing up and down round bearing pin; On two bifurcateds of front end, 4 holes are arranged, fixed the reed pipe pin on 2 middle holes, fixed respectively 2 thread guides in 2 holes foremost;

Described upper pendulum bar is L-shaped, and the rod end that the rear end upwards bends up is ratchet, in the hole of front end, thread guide has been installed, and when front end upwards swung, the ratchet of rear end was just faced upward outward and left ratchet; Front end is during to lower swing, and the ratchet of rear end just blocks ratchet inward; One projection is arranged below upper pendulum bar, in working order under, with the top close contact of draft link.

When the present invention weaves, tension force is adjusted automatically, and fluctuation range is little; During shutdown, the brake stroke is short, and estimable is that braided wires tension force remains unchanged substantially when shutting down, and when the braiding of start continuation next time, keeps original tension force to devote oneself to work, and the corrugated defect of " shutting down shelves " can not appear in braid.

The specific embodiment

Below by drawings and Examples, the present invention is further elaborated.

Embodiment 1:

Structure of the present invention such as Fig. 1-shown in Figure 8, comprising: upper pendulum bar 2, draft link 3, ratchet 5, stage clip 7, spindle shelf 6;

Connected upper pendulum bar 2 and draft link 3 with bearing pin on spindle shelf 6, fixed wire vent thread guide 41 in the middle of spindle shelf 6, wire drawing thread guide 44 has been fixed on the spindle shelf top;

Ratchet 5 bearing pins are connected on spindle shelf 6, and the chassis bayonet socket 11 of two ratchets projection 51 and spindle 1 is flexibly connected, and ratchet 5 can rotate together along with spindle 1;

Referring to Fig. 6, Fig. 8, stage clip 7 be arranged on the concentric spindle shelf hollow pipe of spindle 1 in, stage clip 7 upper ends hold out against spindle shelf 6, the lower end is pressed on by press spring base 71 on the reed pipe pin 31 of draft link, draft link 3 front end depress;

Draft link 3 is all parts of bifurcated of front and back, and is porose on two bifurcateds of rear end, links together with spindle shelf 6 bearing pins, and front end can swing up and down; 4 holes are arranged on two bifurcateds of front end, fixed reed pipe pin 31 on 2 middle holes, fixed respectively 2 thread guides 43 in 2 holes foremost;

Referring to Fig. 5-Fig. 7, described upper pendulum bar 2 is L-shaped, and the rod end that the rear end upwards bends up is ratchet 21, and thread guide 42 has been installed in the hole of front end, and when front end upwards swung, the ratchet 21 of rear end just left ratchet 5 outward; Front end is during to lower swing, and the ratchet 21 of rear end just blocks ratchet 5 inward; One projection 22 is arranged below upper pendulum bar, in working order under, with the top close contact of draft link 3.

Referring to Fig. 2, Fig. 3, braided wires 8 is passed wire vent thread guide 41 after spindle 1 discharges, enter draft link thread guide 43, then the wire drawing thread guide 44 that passes successively upper pendulum bar thread guide 42, draft link thread guide 43, spindle shelf 6 tops participates in braiding, due to pulling of braided wires 8, spindle 1 constantly rotation discharges braided wires 8, and ratchet 5 also rotates together in company with spindle 1 at that time; Due to pulling of braided wires 8, the thrust that draft link 3 has overcome stage clip 7 up swings, the top of draft link 3 heads on the projection 22 of upper pendulum bar 2 toward up, when the front end of upper pendulum bar 2 up swings, the ratchet 21 of rear end is faced upward outward and is left ratchet 5, do not hinder ratchet 5 in company with spindle 1 synchronous rotary, spindle 1 discharges braided wires 8 and participates in braiding.

In the braiding process, just in case braided wires 8 tension force has for some reason reduced, stage clip 7 can be draft link 3 depress, attempt the tension force that keeps original, just in case braided wires 8 tension force has for some reason increased, braided wires 8 can continue draft link 3 up to draw, and in the process of up drawing, reed pipe pin 31 can be by press spring base 71 compression press springs 7.So, the tension fluctuation that in the braiding process, braided wires 8 produces due to the buffering of stage clip 7, has just dwindled the scope of tension fluctuation.

Referring to Fig. 6; when shutting down; braided wires 8 no longer is pulled; the tension force instantaneous reduction; draft link 3 is the past bottom under the promotion of stage clip 7; projection 22 below upper pendulum bar 2 has lost the support of draft link 3; and then toward the bottom; swinging result is that ratchet 21 blocks ratchet 5 inward; ratchet projection 51 is in time braked the spindle 1 of inertial rotation by the bayonet socket 11 that connects, and whole brake stroke can only turn over the gear teeth of 1-2 ratchets, is also that spindle 1 can only turn over part at most; the brake stroke is short, and brake is sensitive, reliable.in brake process, spindle 1 is because the braided wires 8 that inertial rotation discharges is very short, it is also very short that draft link 3 is being pushed away by stage clip 7 distance that falls down, just tangled by braided wires 8 in the air, as shown in Figure 5, because the elasticity of stage clip 7 is arranged to be tried hard to recommend, braided wires 8 continues the tension force that keeping suitable, tension force during with duty differs very little, when starting shooting next time, braided wires 8 will be drawn high the ratchet 21 that backs down upper pendulum bar 2 to draft link 3 and just can work on, tension force has returned to working tension at that time, so partial relaxation " shutdown shelves " defect can not appear in braid, quality is good, work smooth and easy.
