[0024] Specifically, by starting the electric push rod 27, it pushes the rack column 8 to mesh and rotate with the gear 11, thereby starting the working process of the entire equipment. The function of the gear 11 is to transmit the rotational force to the fixed shaft 10, so that the bracket 12 on the outer wall can rotate. The bracket 12, as a connecting component, further drives the fixed plate 14 on the lower surface of the hinge block 13. During the pushing process, the fixed plate 14 is pressed down to drive the limiting roller 1802. The limiting roller 1802 is used in conjunction with the limiting spring 16 to effectively control the downward pressure and avoid excessive damage to the raw material. After completing the above operations, the operator can easily adjust the position of the equipment by pulling the sliding sleeve 4 and utilizing the sliding characteristics of the sliding sleeve 4 to meet different usage requirements. This design makes the equipment more flexible during use and greatly improves work efficiency. In addition, starting the electric push rod 15 and the air gun 6 at the same time can make the air gun 6 quickly approach the raw material for welding operations.

[0025] Reference Figure 1 , Figure 3 and Figure 4The bottom of the inner wall of the workbench 1 is fixedly connected to a support frame 19, one side of the outer wall of the support frame 19 is fixedly connected to a motor 20, and the output end of the motor 20 is fixedly connected to a transmission shaft 21; one side of the outer wall of the workbench 1 is fixedly connected to a bracket 22, and the inside of the bracket 22 is rotatably connected to a roller 25; one end of the roller 25 is fixedly connected to a gear 22, and a belt 26 is provided between the roller 25 and the transmission shaft 21; the upper side of the bracket 22 is rotatably connected to a roller 1 23, and one side of the outer wall of the roller 1 23 is fixedly connected to the outer wall of the roller 1 A gear 3 24 is fixedly connected, and the gear 3 24 is meshed with the gear 2 22; a connecting block 27 is fixedly connected to one side of the upper surface of the workbench 1, a spring column 28 is arranged on the top of the inner wall of the connecting block 27, a sliding block 29 is fixedly connected to the lower surface of the spring column 28, and the sliding block 29 is slidably connected to the inner wall of the connecting block 27; one side of the outer wall of the sliding block 29 is rotatably connected to a limited rotating cylinder 1 30, and a limited rotating cylinder 2 31 is arranged directly below the limited rotating cylinder 1 30, and the limited rotating cylinder 2 31 is rotatably connected to the inside of the workbench 1;

[0026] Specifically, the raw material is passed through the limiting rotating drum 30 and the roller 23. Then, the motor 20 is started, and the transmission shaft 21 is driven by the motor 20 to rotate. The purpose of this step is to drive the entire equipment system to operate and provide power for subsequent processing links. During the rotation of the transmission shaft 21, the roller 25 inside the belt 26 will also rotate. This is due to the close connection between the belt 26 and the transmission shaft 21, so that the belt 26 can effectively transmit the power of the motor 20 to the roller 25. The roller 25 meshes and rotates with the gear 22 and the gear 3 24 to form a precise transmission system. This design is intended to improve the transmission efficiency and stability of the equipment and ensure that the roller 23 can rotate synchronously. The clever cooperation between the roller 23 and the roller 25 achieves the effect of pulling the raw material. During the rotation of the transmission shaft 21, the roller 23 can quickly drive the raw material to be fed, thereby improving production efficiency. At the same time, the reaction force generated by the spring column 28 pushes the sliding block 29 to slide, so that the limiting rotating drum 30 can be tightly pressed against the raw material, effectively preventing the raw material from deviating during the transmission process.

[0027] Working principle: when it is necessary to weld the PVC knife-scraped coating composite material, at this time, the raw material roller is installed on the outer wall of the transmission shaft 21, and the raw material passes through the limiting rotating drum 1 30 and the rotating roller 1 23. At this time, by starting the motor 20, the transmission shaft 21 is driven by the motor 20 to rotate, and the rotating roller 25 inside the belt 26 is driven to rotate, and the rotating roller 2 22 and the gear 3 24 are driven to mesh and rotate through the rotating roller 25, so as to achieve the effect of driving the rotating roller 1 23 to rotate synchronously, and the effect of pulling the raw material is achieved through the cooperation of the rotating roller 1 23 and the rotating roller 2 25. The effect of quickly driving the raw material to be quickly fed is achieved through the rotation of the transmission shaft 21. At this time, the sliding block 29 is pushed to slide by the reaction force of the spring column 28, so as to achieve the effect of driving the limiting rotating drum 1 30 to contact the raw material to prevent the raw material from deviating;

[0028] Secondly, when the raw material is being transmitted, the electric push rod 27 is started, and the rack column 8 is pushed to mesh and rotate with the gear 11 through the electric push rod 27, and the bracket 12 on the outer wall of the fixed shaft 10 is driven to rotate through the gear 11. At this time, the bracket 12 drives the fixed plate 14 on the lower surface of the hinge block 13 to press down, and the fixed plate 14 drives the limiting roller 1802 to contact the raw material to achieve further limiting. The downward pressure is reduced by the limiting spring 16 to reduce the damage to the raw material by the pressure. At this time, the sliding sleeve 4 is pulled and the sliding sleeve 4 slides, so as to achieve the effect of facilitating the adjustment of the position according to the use requirements. At this time, the electric push rod 15 and the air gun 6 are started at the same time, so as to achieve the effect of facilitating the welding operation by bringing the air gun 6 close to the raw material.
