The bar-code label printer that has the carbon ribbon adjusting device
Technical field
The utility model relates to bar-code label printer, is specifically related to a kind of bar-code label printer that has the carbon ribbon adjusting device.
Background technology
The industrial bar-code label printer of prior art is because of reason such as poor working environment and print job amount be big, the following problem of the easiest in actual use generation: long loosening the walking of bound fraction of causing metal parts of, working time fast because of print speed, cause problems such as carbon ribbon is crumpled, displacement, make printing effect poor, sometimes even can't print thereby influence precision.So industrial label machine generally all has the carbon ribbon adjusting device, regulate the carbon ribbon equalization of strain, solve the carbon ribbon problem of " crumpling ".But adjusting way in the past mainly is the direction of regulating the axle of carbon ribbon feed end.Because the axle of carbon ribbon feed end is a stressed member, cause so the axle of carbon ribbon feed end is made adjustable meeting: (1) reliability reduces; (2) need after big intensity locking and the locking bounce-back error is arranged after the adjusting, so regulate complexity and poor effect.
The utility model content
The technical problems to be solved in the utility model is, at the above-mentioned defective of prior art, provides a kind of bar-code label printer that has the carbon ribbon adjusting device.
A kind of bar-code label printer that has the carbon ribbon adjusting device, comprise Support for impression mechanism, be installed in printhead and carbon ribbon feed end in the described Support for impression mechanism, also comprise the carbon ribbon adjusting device that is installed in the described Support for impression mechanism, described carbon ribbon adjusting device is arranged between described printhead and the carbon ribbon feed end, described carbon ribbon adjusting device has at least the position of an end adjustable, and the carbon ribbon of extracting out from described carbon ribbon feed end passes described carbon ribbon adjusting device and described printhead successively.
In the bar-code label printer that has a carbon ribbon adjusting device described in the utility model, described carbon ribbon adjusting device is a rod shaped structure.
In the bar-code label printer that has a carbon ribbon adjusting device described in the utility model, the adjustable side of described carbon ribbon adjusting device is passed the through hole and the adjustment sheet of described Support for impression mechanism and is fixed, the size of described through hole is greater than the external diameter of described carbon ribbon adjusting device, one end of described adjustment sheet is fixed by hold-down screw and described Support for impression mechanism, the other end of described adjustment sheet is provided with adjustment hole, adjustment screw is passed described adjustment hole and is fixed on the described Support for impression mechanism, and the diameter of described screw nut is greater than the width of described adjustment hole.
In the bar-code label printer that has a carbon ribbon adjusting device described in the utility model, described adjustment sheet is fan-shaped.
In the bar-code label printer that has a carbon ribbon adjusting device described in the utility model, described Support for impression mechanism is provided with scale, and described adjustment sheet is provided with the pointer that points to described scale.
In the bar-code label printer that has a carbon ribbon adjusting device described in the utility model, described adjustment hole is waist shape, strip.
The beneficial effects of the utility model are, because the carbon ribbon adjusting device of bar-code label printer of the present utility model is used the carbon ribbon axis of guide, one end of the carbon ribbon axis of guide is made and can be regulated, can carbon ribbon evenly be tightened by the direction of regulating the carbon ribbon axis of guide, solve the carbon ribbon problem of " crumpling ".Because the carbon ribbon axis of guide is stressed very little, so adjusting device is simple in structure, be very easy to realize, cost is also very low that it is time saving and energy saving to regulate, only needs the user to do it yourself to stir gently the adjusting head, locking and regulating device got final product after range estimation carbon ribbon tension force was average.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples, in the accompanying drawing:
Fig. 1 is the structural representation that bar-code label printer of the present utility model is unkitted a kind of embodiment of carbon ribbon;
Fig. 2 is the structural representation that bar-code label printer of the present utility model is equipped with a kind of embodiment of carbon ribbon;
Fig. 3 is a kind of structural representation of embodiment of the adjusting head of bar-code label printer of the present utility model.
The specific embodiment
Fig. 1 shows the structural representation that bar-code label printer of the present utility model is unkitted a kind of embodiment of carbon ribbon, wherein bar-code label printer includes Support for impression mechanism, is installed in printhead, carbon ribbon feed end 2, carbon ribbon adjusting device 3 in the Support for impression mechanism, and wherein carbon ribbon adjusting device 3 is arranged on (parallel with it) between printhead and the carbon ribbon feed end 2.An end of carbon ribbon adjusting device 3 is fixed an end position and can be regulated in the present embodiment, and wherein stiff end 301 is fixing, and the position of adjustable side 302 can be regulated.It is outside fixing with adjustment sheet 4 that the through hole that Support for impression mechanism is passed in the adjustable side 302 of carbon ribbon adjusting device 3 stretches to printer, and the size of through hole wherein is bigger so that 302 shift positions, adjustable side than the external diameter of carbon ribbon adjusting device 3.Be illustrated in figure 3 as a kind of structural representation of embodiment of the adjusting head of bar-code label printer of the present utility model, adjustment sheet 4 is fan-shaped in the present embodiment, one end of adjustment sheet 4 is fixed on the Support for impression mechanism by hold-down screw 5, the other end of adjustment sheet 4 is provided with adjustment hole 6 and pointer 7, adjustment screw 8 is passed adjustment hole 6 and is fixed on the Support for impression mechanism, the nut section diameter of adjustment screw 8 is decorated with scale 9 greater than the width of adjustment hole 6 on Support for impression mechanism, pointer 7 points to scale 9.Control method is, unclamp hold-down screw 5 and adjustment screw 8, stir adjustment sheet 4, the position of the scale 9 of pointer 7 correspondences can be moved thereupon, also move thereupon the position of corresponding carbon ribbon adjusting device 3, because carbon ribbon passes carbon ribbon adjusting device 3, the position of carbon ribbon is also moved and is moved (as shown in Figure 2) along with the position of carbon ribbon adjusting device 3, thereby with the tension adjustment of the carbon ribbon position to balance, and then tighten hold-down screw 5 and adjustment screw 8, the position of carbon ribbon adjusting device 3 is just fixing like this.Because carbon ribbon balance adjustment bar 3 is stressed very little, so be easy on the structure realize.
The utility model can also have other embodiment, for example the two ends of carbon ribbon adjusting device 3 all can be set to the position can regulate, and two ends all are provided with adjustment sheet 4, during adjusting the adjustment sheet 4 at two ends to stir direction opposite, the adjustable range of this embodiment is bigger, and degree of regulation is higher.
The utility model can also have other embodiment, and for example, adjustment sheet 4 can also be set to other shapes, for example can be set to rectangle etc., and adjustment hole 6 also can be set to other shapes, for example can be strip.
