Abstract

Bar-code label printer with a carbon ribbon adjusting apparatus includes a framework, a print head provided on the framework, a carbon ribbon supply reel, and an adjusting apparatus located between the print head and the carbon ribbon supply reel. At least one end of the adjusting apparatus is adjustable, a carbon ribbon from the supply reel pass through the adjusting apparatus and the print head successively. By suitable setting of the direction of the carbon ribbon guide rod, a uniform tension is applied across the ribbon tape to prevent wrinkling thereof in the bar-code label printer. As only a little stress has been applied upon the guide rod, the adjusting apparatus has the advantages of simple structure, low cost and convenient operation. Users manually set the adjusting member, and fasten the adjusting apparatus when the tension of the carbon ribbon determined by eyeballing is suitable.

Description

Bar code label printer with ribbon adjustment device

The present invention relates to a bar code label printer, and more particularly to a bar code label printer with a ribbon adjustment device. Background technique

The prior art industrial bar code label printer is most prone to the following problems in practical use due to poor working environment and large printing workload, etc.: Due to the fast printing speed and long working time, the combined parts of the metal parts are loosely moved, resulting in The problem of wrinkling, shifting, etc. of the ribbon, which affects the accuracy, makes the printing effect poor, and sometimes even impossible to print. Therefore, industrial label printers generally have a ribbon adjustment device that adjusts the balance of the ribbon tension to solve the "wrinkle" problem of the ribbon. However, the previous adjustment method was mainly to adjust the direction of the shaft at the supply end of the ribbon. Because the shaft at the supply end of the ribbon is a force-carrying component, making the shaft of the ribbon supply end adjustable can result in: (1) reduced reliability; (2) high-strength locking after adjustment and rebound error after locking, So the adjustment is complicated and the effect is not good. Summary of the invention

The technical problem to be solved by the present invention is to provide a bar code label printer with a ribbon adjustment device in view of the above-mentioned drawbacks of the prior art.

A barcode label printer with a ribbon adjustment device, comprising a printer holder, a print head and a ribbon supply end mounted in the printer holder, and a ribbon adjustment device mounted in the printer holder, a ribbon adjusting device is disposed between the print head and the ribbon supply end, the ribbon adjustment device The position of at least one end is adjustable, and the carbon ribbon drawn from the supply end of the ribbon passes through the ribbon adjusting device and the print head in sequence.

In the bar code label printer with a ribbon adjusting device according to the present invention, the ribbon adjusting device has a rod-like structure.

In the barcode label printer with a ribbon adjustment device according to the present invention, the adjustment end of the ribbon adjustment device is fixed to the regulating piece through the through hole of the printer frame, and the size of the through hole is larger than the An outer diameter of the ribbon adjusting device, one end of the adjusting piece is fixed to the printer frame by a fixing screw, and the other end of the adjusting piece is provided with an adjusting hole, and the adjusting screw is fixed to the printer frame through the adjusting hole The screw nut has a diameter larger than a width of the adjusting hole.

In the bar code label printer with a ribbon adjusting device according to the present invention, the regulating piece has a fan shape.

In the bar code label printer with a ribbon adjustment device according to the present invention, the printer holder is provided with a scale, and the adjustment sheet is provided with a pointer pointing to the scale.

In the bar code label printer with a ribbon adjustment device according to the present invention, the adjustment hole is formed in a waist shape or a strip shape.

The invention has the beneficial effects that since the ribbon adjusting device of the bar code label printer of the invention borrows the ribbon guiding shaft, the end of the ribbon guiding shaft can be adjusted, and the ribbon can be adjusted by adjusting the direction of the ribbon guiding shaft Both are taut and solve the problem of "wrinkle" of the ribbon. Because the belt guide shaft has a small force, the adjustment device has a simple structure, is very easy to implement, and has low cost. The adjustment saves time and effort. Only the user needs to manually push the adjustment head, and visually measure the belt tension after the lock. Just adjust the device. DRAWINGS

The present invention will be further described below in conjunction with the accompanying drawings and embodiments, in which: 1 is a schematic structural view of an embodiment of a bar code label printer of the present invention without a carbon ribbon; FIG. 2 is a schematic structural view of an embodiment of a bar code label printer of the present invention with a carbon ribbon; A schematic structural view of an embodiment of an adjustment head of a bar code label printer. detailed description

1 is a schematic structural view showing an embodiment of a bar code label printer of the present invention without a carbon ribbon, wherein the barcode label printer includes a printer frame, a print head mounted in the printer frame, a ribbon supply end 2, and a ribbon. The adjusting device 3, wherein the ribbon adjusting device 3 is disposed between (parallel to) the print head and the ribbon supply end 2. In the embodiment, the fixed end of one end of the ribbon adjusting device 3 can be adjusted, wherein the fixed end 301 is fixed, and the position of the adjusting end 302 can be adjusted. The adjusting end 302 of the ribbon adjusting device 3 extends through the through hole of the printer frame to the outside of the printer and is fixed to the regulating piece 4, wherein the through hole is larger in size than the outer diameter of the ribbon adjusting device 3 to facilitate the moving position of the adjusting end 302. . FIG. 3 is a schematic structural view of an embodiment of an adjustment head of a bar code label printer according to the present invention. In the embodiment, the adjustment piece 4 has a fan shape, and one end of the adjustment piece 4 is fixed on the printer frame by a fixing screw 5, The other end of the adjusting piece 4 is provided with an adjusting hole 6 and a pointer 7. The adjusting screw 8 is fixed on the printer frame through the adjusting hole 6. The diameter of the nut portion of the adjusting screw 8 is larger than the width of the adjusting hole 6, and is drawn on the printer frame. Scale 9, the pointer 7 points to the scale 9. The adjustment method is: loosening the fixing screw 5 and the adjusting screw 8, and moving the adjusting piece 4, the position of the scale 9 corresponding to the pointer 7 will move accordingly, and the position of the corresponding ribbon adjusting device 3 also moves, due to the ribbon Passing through the ribbon adjusting device 3, the position of the ribbon is also moved as the position of the ribbon adjusting device 3 moves (as shown in FIG. 2), thereby adjusting the tension of the ribbon to a balanced position, and then tightening the fixing screw. 5 and the adjusting screw 8, so that the position of the ribbon adjusting device 3 is fixed. Since the force of the ribbon balance adjustment lever 3 is small, it is structurally easy to implement.

The present invention may have other embodiments, for example, both ends of the ribbon adjusting device 3 may be provided. The position can be adjusted, and the adjusting piece 4 is arranged at both ends. When the adjusting piece 4 at both ends is adjusted in the opposite direction, the adjustment range of the embodiment is larger and the adjustment precision is higher.

Other embodiments may be used in the present invention. For example, the regulating piece 4 may be provided in other shapes, for example, may be provided in a rectangular shape or the like, and the adjusting hole 6 may be provided in other shapes, for example, may be elongated.
