[0027] In order to improve the coding quality of the material belt, the utility model proposes a coding device, comprising:

[0028] The supporting roller group 100 supports the material belt and is in rolling connection with the material belt;

[0029] The adsorption member 200 is disposed on one side of the supporting roller group 100. The adsorption member 200 has an adsorption surface, and the adsorption surface is used to adhere to and adsorb the material belt;

[0030] The coding machine 300 is disposed on one side of the adsorption member 200 , and the coding machine 300 is opposite to the adsorption surface.

[0031] Compared with the prior art, in the technical solution of the present utility model, the coding device includes a supporting roller group 100, which is used to support the material belt, and the material belt is rollingly connected to the supporting roller group 110. One side of the supporting roller group 110 is provided with an adsorption member 200, and the adsorption member 200 is provided with an adsorption surface, which is in contact with and adsorbs the material belt, so as to prevent the material belt from shaking when passing through the adsorption surface. In addition, a coding machine 300 is provided on one side of the adsorption member 200, and the coding machine 300 is opposite to the position of the adsorption surface, and codes the material belt passing through the adsorption surface; in the present technical solution, the material belt can be adsorbed by the adsorption member 200 to stabilize the position of the material belt during coding, thereby improving the coding quality. In addition, the supporting roller group 100 is provided on one side of the adsorption member 200 to improve the support for the material belt, thereby reducing the shaking of the material belt at other positions except the adsorption surface, which is conducive to further improving the coding quality.

[0032] like Figures 1 to 3 In one embodiment of the utility model, the coding device includes a supporting roller group 100, which is composed of rollers. The supporting roller group 100 can be rotatably arranged on a bracket, and the material belt is covered on the supporting roller group 100 and is rollingly connected with the supporting roller group 100; an adsorption member 200 is arranged on one side of the supporting roller group 100, and the adsorption member 200 can be arranged side by side with the supporting roller group 100. The adsorption surface is provided on the adsorption member 200, and the adsorption surface is a plane. The adsorption member 200 can be arranged on the conveying line of the material belt, and the adsorption surface and the material belt can be attached and the material belt is tightly attached to the adsorption surface by negative pressure adsorption. Close fit; in addition, a coding machine 300 is arranged on the side opposite to the adsorption surface, and the coding machine 300 can emit laser toward the adsorption surface to code the material belt on the adsorption surface. Since the material belt is tightly adsorbed by the adsorption surface, the material belt on the adsorption surface will not shake during the coding process, which can improve the quality of coding. In addition, the setting of the supporting roller group 100 can improve the supporting effect on the material belt and prevent the wear of the material belt caused by excessive pressure between the material belt and the adsorption surface. In addition, the supporting roller group 100 can also tighten the material belt to reduce the shaking of the material belt in other areas except the adsorption surface, which is conducive to further preventing the shaking of the material belt.

[0033] like Figure 2In one embodiment of the utility model, the supporting roller group 100 includes two supporting rollers 110, the two supporting rollers 110 are arranged in parallel and at intervals, and the adsorbent 200 is arranged between the two supporting rollers 110. The two supporting rollers 110 are respectively arranged on opposite sides of the adsorbent 200 along the conveying direction of the material belt, and the two supporting rollers 110 are arranged adjacent to the adsorbent 200. In this way, during the conveying process from the material belt arriving at the adsorbent 200 to leaving the adsorbent 200, the two supporting rollers 110 always provide support for the material belt, thereby helping to reduce the pressure between the material belt and the adsorbent 200 and prevent the material belt from being worn. In addition, the material belt portion between the two supporting rollers 110 is isolated by the two supporting rollers 110, and the vibration of the material belt outside the two supporting rollers 110 can be filtered by the two supporting rollers 110, which helps to further reduce the vibration of the material belt on the adsorption surface.

[0034] like Figure 2 and Figure 3 In one embodiment of the utility model, a negative pressure cavity is provided in the adsorption member 200, and adsorption holes 210 are provided on the adsorption surface, and the adsorption holes 210 are connected to the negative pressure cavity. The adsorption member 200 can be a rectangular parallelepiped structure, and a negative pressure cavity is provided in the adsorption member 200. A joint can be provided on one side of the adsorption member 200 to be connected to the negative pressure cavity, and the joint is connected to the negative pressure generating device to form a negative pressure environment in the negative pressure cavity. In addition, adsorption holes 210 can be provided on the adsorption surface, and the aperture and arrangement of the adsorption holes 210 can be set at will. The adsorption holes 210 are connected to the negative pressure cavity. In this way, when the material belt passes through the adsorption surface, the material belt can be adsorbed by multiple adsorption holes 210.

[0035] like Figure 3 In one embodiment of the utility model, a plurality of adsorption holes 210 are arranged in a matrix in the conveying direction of the material belt. In the technical scheme, the number of columns and rows of the matrix can be flexibly set according to the needs, and the matrix arrangement method can make the adsorption force on the adsorption surface of the material belt uniform, thereby preventing the material belt from being damaged due to excessive force on a part of the material belt.

[0036] like Figure 1 In one embodiment of the present invention, the coding device includes a driving roller 400, which is disposed on one side of the supporting roller group 100 and is connected to the material belt drive. Figure 1 In this solution, the driving roller 400 includes a roller wheel and a motor for the driving roller 400. The driving roller 400 is arranged downstream of the supporting roller group 100 in the conveying direction of the material belt. The driving roller 400 is connected to the material belt drive to drive the material belt to move. The driving roller 400 and the supporting roller group 100 can tension the material belt, which can further reduce the jitter of the material belt and further improve the coding quality.

[0037] like Figure 1In one embodiment of the utility model, the coding device further includes an encoder 500, which is coaxially connected to the driving roller 400, and the encoder 500 is electrically connected to the coding machine 300. The encoder 500 can detect the rotation speed of the driving roller 400, and the encoder 500 can be connected to the PLC, and the coding machine 300 is also connected to the PLC. In this way, the PLC can determine the conveying speed on the material belt according to the rotation speed of the driving roller 400 detected by the encoder 500, and then control the coding machine 300 to adjust the coding speed to ensure that the laser coding speed matches the tape speed, and prevent the two-dimensional code from being elongated or shortened.

[0038] like Figure 1 In this embodiment, the coding device further includes a pressing roller 600, which is parallel to and spaced from the driving roller 400, and cooperates with the driving roller 400 to clamp the material belt. The clamping of the material belt by the pressing roller 600 and the driving roller 400 can improve the driving force of the driving roller 400 on the material belt, prevent the material belt from slipping and affecting the normal conveyance of the material belt, and improve the reliability of the coding device.

[0039] like Figure 1 In one embodiment of the utility model, the coding device further includes a roller 700, and the roller 700 and the driving roller 400 are staggered with the supporting roller group 100 to increase the contact area between the material belt and the supporting roller group 100. The roller 700 and the driving roller 400 are both located on the same side of the supporting roller group 100, so that the material belt can be more covered on the supporting roller group 100, thereby increasing the friction between the material belt and the supporting roller group 100, and preventing the material belt from slipping and damaging the material belt.

[0040] The utility model also proposes a coding device, which includes a device body and a coding device arranged on the device body. The specific structure of the coding device refers to the above embodiment. Since the coding device adopts all the technical solutions of all the above embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be repeated here one by one.

All equivalent structural changes made by using the contents of the present invention specification and drawings under the technical concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
