Description

Flattening device and wire marking machine with same

Technical Field

The utility model relates to the technical field of printing tools, in particular to a flattening device and a wire marking machine with the flattening device.

Background

The line marking machine may be used to print text or symbols to the sleeve for equipment, line management and instruction. To facilitate planar printing, the sleeve needs to be flattened. A conventional wire marking machine, for example, a wire marking machine provided in patent document CN201086461Y, uses a print head and a glue roller arranged in parallel to flatten a sleeve, and prints text symbols on the flattened sleeve body.

However, using printheads and glue rollers to collapse the sleeve may result in the sleeve not being completely collapsed due to less printhead pressure or thicker sleeve walls. But collapsing the sleeve before printing is the basis for ensuring that the print head and sleeve are in sufficient contact to ensure print quality. If the sleeve is not fully flattened, insufficient contact between the print head and the sleeve can occur, such as lack of character blurring, thereby affecting print quality.

And the existing rubber roller is made of rubber, deformation can be generated after long-time bearing for flattening treatment, and the deformation of the rubber roller can directly influence the printing quality. For example, the rubber roller deforms to cause the friction force to change, the sleeve cannot normally pass through in the printing process, and the sleeve slips, stays and the like, so that misprinting and missing printing are caused, and printing is repeated at a certain point.

Therefore, how to achieve sufficient flattening of the sleeve to ensure its print quality is a problem to be solved by those skilled in the art.

The thread marking machine is typically provided with a conveyor, a print head and a glue roller. According to an aspect of the present utility model, there is provided a flattening device adapted to be secured to a wire marking machine, wherein the wire marking machine comprises a conveyor, a flattening device, a glue roll and a print head. The conveying device is used for driving the sleeve to move; the flattening device is used for flattening the sleeve; and the print head and the glue roller act as printing means to print characters on the sleeve.

In the process of printing the sleeve by the line marking machine, the conveying device drives the sleeve to displace, the rubber roller and the printing head are arranged oppositely, and the sleeve penetrates into a gap between the rubber roller and the printing head from one side of the rubber roller, namely the pipe inlet side of the rubber roller and the printing head, and performs thermal transfer printing in the region.

The flattening device is suitable for being fixed on a wire marking machine and is arranged close to the tube inlet side of the rubber roller and the printing head. As shown in fig. 1 to 5, the flattening apparatus includes: a base 110 and a limiting portion; the limiting part comprises a first limiting part 120 and a second limiting part 130; the first limiting portion 120 and the second limiting portion 130 are fixed on the same side face of the base 110, the first limiting portion 120 and the second limiting portion 130 are respectively close to two opposite ends of the base 110, and the first limiting portion 120 is suitable for being arranged close to a pipe inlet side face of the rubber roller 400 of the wire marking machine.

Before the flattening device is installed on the marking machine, the position of the flattening device on the marking machine is first checked. The flattening device is integrally disposed adjacent to the glue roller 400 and the feed side of the printhead 300. The first limiting portion 120 is disposed near an end of the base 110, and the first limiting portion 120 is disposed near a side of the tube feeding portion of the rubber roller 400 of the wire marking machine. Because the first limiting portion 120 and the second limiting portion 130 are respectively located at two opposite ends of the base 110, the first limiting portion 120 is located between the second limiting portion 130 and the rubber roller 400. It should be noted that, the specific distance between the first limiting portion 120 and the rubber roller 400 is not limited, and the distance is flexibly set according to the pipe diameter of the sleeve to be flattened.

The sleeve is S-shaped, sequentially bypasses the second limiting part and the first limiting part, then enters a printing area between the rubber roller and the printing head for printing, and compared with the traditional mode that the rubber roller and the printing head are arranged oppositely and the sleeve is flattened, the sleeve is bent twice through the second limiting part and the first limiting part and then printed, so that the sleeve is flattened more fully, and the printing effect is improved.

The operator penetrates the sleeve one end that will constantly convey from the one side that the second spacing portion 130 deviates from first spacing portion 120 into flattening device, makes the sleeve pipe be located on base 110, passes between first spacing portion 120 and the second spacing portion 130, makes first spacing portion 120 and second spacing portion 130 be located the relative both ends of this sleeve pipe body width direction respectively, through setting up first spacing portion 120 and second spacing portion 130, carries out the pre-flattening with the sleeve pipe, makes the sleeve pipe get into the printing region between rubber roll 400 and the print head 300 with the platykurtic. Specifically, when the sleeve is located between the second limiting portion 130 and the first limiting portion 120, the sleeve is stressed and flattened once due to the limiting tightening of the two ends and the continuous driving of the conveying device; before penetrating into the gap between the first limiting part 120 and the rubber roller 400, the sleeve bypasses the outer side wall of the first limiting part 120 to be bent once, and at the moment, the sleeve is stressed to be flattened for the second time because of the limiting of the rubber rollers at the two ends of the bending part and the second limiting part and the continuous driving of the conveying device; then, the sleeve penetrates between the first limiting part 120 and the rubber roll 400, and because the first limiting part 120 is arranged close to one side surface of the rubber roll 400, the sleeve is flattened for three times between the first limiting part 120 and the rubber roll 400.

Because the crimping device pre-crimps the sleeve, the sleeve is substantially crimped as it passes into the print area between the print head and the glue roller. At the moment, the printing head and the rubber roller only need to perform a printing function, compared with the flattening device of the traditional line marking machine, the flattening device is flattened through the printing head and the rubber roller, the rubber roller is deformed due to long-term compression, and the printing quality of the sleeve is seriously affected. And even because the pipe diameter of the sleeve is too large, the printing head and the rubber roller still need to be flattened, the deformation amount of the sleeve is smaller, and the flattening pressure of the printing head and the rubber roller can be relieved. Compared with the flattening device of the traditional thread marking machine, the flattening device is flattened for one time only through the printing head and the rubber roller, if the flattening device cannot flatten due to the fact that the pipe wall is too thick, the bending part is supported, and the like, the flattening device can only complete flattening by increasing the pressure of the printing head, and the rubber roller is large in pressure bearing and easy to deform to influence printing quality. The utility model completes flattening while keeping the pressure of the printing head unchanged, reduces the deformation amount of the rubber roller, prolongs the service life of the rubber roller and ensures the printing quality.

Before the flattening device is installed on the marking machine, the position of the flattening device on the marking machine is first checked.
