[0002] The applicant has previously applied for and been granted a Chinese utility model patent with the announcement number CN219789339U for a material stitching machine structure. An automatic stitching machine has a main structure including a material transmission mechanism, which includes a frame, a left frame and a right frame, a material unloading space is left between the left frame and the right frame, a feeding part is installed on both the left frame and the right frame, and a welding and cutting part is also installed on the frame, which is used to weld and cut the material in the unloading space into a material circle. It also includes a first positioning block and a second positioning block, the first positioning block is fixed on the left frame, the second positioning block is slidably connected to the left frame, and a positioning space for the material to pass through is formed between the first positioning block and the second positioning block, and the size of the positioning space can be adjusted by moving the position of the second positioning block; a fixed material block is arranged above the welding and cutting part, and the fixed material block can be against the side walls of the first positioning block and the second positioning block, and the material at this position can be limited in the positioning space.

[0003] Although the above structure can basically and effectively complete the cutting and welding actions of the material, after long-term use, it is found that due to the drooping and shaking force generated when the material is formed in the unloading space, the material is easily entered between the first positioning block and the fixed material block, and between the second positioning block and the fixed material block, which ultimately affects the subsequent processing. There is room for further optimization. Utility Model Content

[0004] In view of this, the purpose of the utility model is to provide a material anti-deviation mechanism, which can effectively reduce the probability of lateral deviation of the material.

[0005] In order to solve the above technical problems, the technical solution of the utility model is:

[0006] A material deviation prevention mechanism, comprising a left material transmission mechanism and a right material transmission mechanism, wherein a material unloading space is reserved between the left material transmission mechanism and the right material transmission mechanism, wherein a positioning block group is arranged on the left material transmission mechanism close to the material unloading space, and a welding and cutting piece, a material fixing block and a material fixing driving part are arranged on the right material transmission mechanism, wherein the material fixing driving part is used to drive the material fixing block to move close to or away from the positioning block group, and the welding and cutting piece is used to weld and cut the material in the material unloading space into a material circle;

[0007] The side wall of the positioning block group close to the material setting block is provided with a positioning protrusion, and the side wall of the material setting block close to the positioning block group is provided with a positioning groove;

[0008] When the positioning block group and the material fixing block abut against each other, the positioning grooves are engaged with each other.

[0009] Through the above technical solution, during the material transmission and processing process, the material fixing drive unit will drive the material fixing block to one side of the material fixing block, the positioning protrusion on the positioning block group will be interlocked with the positioning groove on the material fixing block, and the fitting bending degree between the side wall of the positioning block group and the side wall of the material fixing block is significantly improved, and the probability of the material accidentally deviating from the side wall of the positioning block group and the side wall of the material fixing block is greatly reduced.

[0010] Preferably, the positioning block group includes a first positioning block and a second positioning block, the first positioning block and the second positioning block are both provided with the positioning protrusions on their side walls, and a positioning space for materials to pass through is formed between the first positioning block and the second positioning block.

[0011] Through the above technical solution, the material can pass through the positioning space between the first positioning block and the second positioning block. Accordingly, positioning protrusions are provided on the first positioning block and the second positioning block, so that the material can be stably confined between the first positioning block and the second positioning block.

[0012] Preferably, the first positioning block and the second positioning block are both slidably connected to the side wall of the left material transmission mechanism.

[0013] Through the above technical solution, the relative position between the first positioning block and the second positioning block can be adjusted according to the width of materials in different batches, and ultimately the size of the positioning space can be controlled.

[0014] Preferably, an inclined guide surface is provided at the upper end of the fixing block.

[0015] Through the above technical solution, since the material fixing block will be driven by the material fixing drive part to move toward the side of the positioning block group, at this time, the descending material can also contact the inclined guide surface. The inclined guide surface can guide the material into the positioning space more smoothly and reduce the amount of contact wear on the material.

[0016] Preferably, it also includes a left baffle and a right baffle, both of which are located below the material unloading space, the left baffle is installed on the left material conveying mechanism, and the right baffle is installed on the right material conveying mechanism, and a material blocking space is formed between the left baffle and the right baffle.

[0017] Through the above technical solution, the material blocking space formed between the left baffle and the right baffle can produce a resistance and limiting effect on the lower end of the material, and the upper end of the material is located in the positioning space, so the entire material can be effectively limited.

[0018] Preferably, the end of the left baffle plate close to the material blocking space and the end of the right baffle plate close to the material blocking space are both provided with bent ends.

[0019] Through the above technical solution, on the one hand, the effective contact area between the material and the bent ends of the left baffle and the right baffle is greatly improved, and the limiting effect is enhanced; on the other hand, the bent ends can also guide the material to descend and form more stably.

[0020] Preferably, the bending direction of the bent end is downward.

[0021] Through the above technical solution, the descending material will first contact the bending point of the bending end. Since the bending direction of the bending end is downward, the bending point is located at the upper position, and the contact between the material and the left baffle and the right baffle will be smoother.

[0022] Preferably, the right baffle is mounted on a driving end of the material fixing drive unit, and the material fixing drive unit can drive the right baffle to move closer to or away from the left baffle.

[0023] Through the above technical solution, the material feed drive unit can drive the right baffle to move toward the left baffle, and the distance between the left baffle and the right baffle will be reduced, which can produce two-sided materials in the material feed space.

The material fixing drive unit 7 can select a cylinder, and the material fixing drive unit 7 is used to drive the material fixing block 6 to move closer to or away from the positioning block group 4. The welding and cutting piece 5 is used to weld and cut the material in the unloading space 3 into a material circle.

A positioning groove 9 is provided on the side wall of the dosing block 6 close to the positioning block group 4, and the side wall of the dosing block 6 provided with the positioning groove 9 forms a second step surface. When the positioning block group 4 and the dosing block 6 are against each other, the positioning groove 9 and the positioning groove 9 are interlocked with each other, that is, the first step surface and the second step surface are in contact with each other, thereby effectively improving the fitting bending degree between the side wall of the positioning block group 4 and the side wall of the dosing block 6.
