The top layer of this surface film is paint, the middle layer is mainly polyvinyl chloride, and the bottom layer is a backing adhesive. It is a popular and widely used synthetic material in the world today. PVC pipes are extruded and cooled simultaneously on the production line, and the extruded PVC pipes need to be traction and conveyed. Existing technology publication number CN206983208U discloses a traction machine for PVC pipe production, including a base, a housing fixedly connected to the upper end of the base, support plates fixedly welded to the inner wall of the housing, a spring fixedly connected to one side of the support plate, a spring fixing plate fixedly connected to the other end of the spring, a bearing seat fixedly connected to one side of the spring fixing plate, a bearing embedded inside the bearing seat, a roller shaft installed between the bearings, a traction groove provided on the outer surface of the roller shaft, an inlet at one end of the housing, an outlet at the other end of the housing, an upper support plate fixedly connected to the spring fixing plate on one side by a fixing column, and a motor connected to one side of the upper roller shaft by a transmission rod. However, the traction efficiency is low, and it cannot effectively traction according to the specifications and dimensions of the pipe, resulting in a narrow application range and affecting the processing quality of the plastic pipe. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a PVC food-grade plastic hose processing traction device that can adjust the traction position, facilitate the traction and transportation of pipes of different diameters, ensure the overall quality of PVC pipes, and improve traction efficiency.

[0004] This utility model discloses a traction device for processing PVC food-grade plastic hoses, comprising a workbench, a supporting conveying component, a pressing component, a traction component, an adjusting component, and a supporting component. The supporting conveying component is installed at the center of the top of the workbench, the pressing component is installed on the top of the workbench above the supporting conveying component, the traction component is installed at the front and rear ends of the top of the workbench via the adjusting component, and the supporting component is installed at the bottom of the workbench. The supporting component supports the bottom of the workbench and is installed at the rear end of the pipe cooling tank. After the PVC pipe is extruded and cooled, it enters between the supporting conveying component and the pressing component. The traction component pulls the PVC pipe, and the adjusting component can adjust the distance between the front and rear traction components, facilitating the traction and conveying of pipes of different diameters, ensuring the overall quality of the PVC pipe, and improving the traction efficiency.

[0005] Preferably, the supporting conveying component includes a conveying seat and multiple lower conveying rollers. The conveying seat is installed at the top center of the workbench, and multiple lower conveying rollers are evenly rotated and mounted on the conveying seat. After the PVC pipe is extruded and cooled, it moves on the multiple lower conveying rollers to support and convey the PVC pipe.

[0006] Preferably, the pressing component includes two sets of upright legs, two horizontal plates, a crossbeam, multiple T-shaped slide rods, an upper conveyor seat, multiple upper conveyor pressure rollers, and multiple springs. Upright legs are installed on the left and right sides of the top of the worktable, and horizontal plates are installed on the top of the upright legs. A crossbeam is installed between the two horizontal plates. Multiple T-shaped slide rods are evenly slidably installed on the crossbeam. An upper conveyor seat is installed at the bottom of the T-shaped slide rods. Multiple upper conveyor pressure rollers are evenly rotatably installed at the bottom of the upper conveyor seat. Springs are fitted on the upper part of the T-shaped slide rods, and the bottom of the springs is connected to the top of the crossbeam. When the PVC pipe is extruded and cooled, it moves on the lower conveyor rollers. The springs pull the T-shaped slide rods to slide on the crossbeam. The T-shaped slide rods push the upper conveyor seat, causing the upper conveyor pressure rollers to contact the top of the PVC pipe, thus pressing the PVC pipe. This is suitable for pipes of different diameters.

[0007] Preferably, the adjusting component includes two fixed plates, a dual-output motor, two threaded rods, two adjusting plates, and two sliding plates. An adjusting groove is formed at the center of the top of the worktable. Fixed plates are installed at both ends of the adjusting groove. The dual-output motor is installed in the center of the adjusting groove. Threaded rods are installed at the output ends of the dual-output motor on both sides. The threaded rods are rotatably mounted on the fixed plates. The adjusting plate is screwed onto the outer wall of the threaded rods in the center. A sliding plate is installed at the center of the top of the adjusting plate and is slidably mounted within the adjusting groove. Starting the dual-output motor drives the threaded rods to rotate, which pushes the adjusting plates to move at the bottom of the worktable, thus pushing the sliding plates to slide within the adjusting groove. This allows for adjustment of the traction position and is suitable for pipes of different diameters, improving practicality.

[0008] Preferably, the traction component includes two adjusting seats, two sets of electric telescopic rods, two traction seats, two sets of traction wheels, two traction belts, and two traction motors.

Rubber strips are provided on the outer surface of the traction belts. The traction motors are installed on the top of the traction seats, and the output end of the traction motors is connected to the input end of one of the traction wheels. When the electric telescopic rods are started, they push the traction seats up and down, so that the traction belts are located in the middle of the front and rear ends of the PVC pipe. When the traction motors are started, they drive the traction wheels to rotate, thereby rotating the traction belts and tractioning and conveying the PVC pipes. The rubber strips can increase friction and ensure traction quality.

[0009] Preferably, the device also includes two sets of connecting plates and two guide slide rods. Guide slide grooves are provided at both ends of the worktable, and connecting plates are installed at the front and rear ends of the guide slide grooves. Guide slide rods are installed between the two connecting plates. The left and right ends of the adjustment plate are slidably installed on the outer wall of the guide slide rods. Guide sliders are provided at the top of the left and right ends of the adjustment plate. The guide sliders are slidably installed in the guide slide grooves, and the top of the guide sliders are connected to the bottom of the adjustment seat. When the adjustment plate moves, it slides on the guide slide rods to guide the sliding. At the same time, the adjustment plate drives the guide sliders to slide in the guide slide grooves, which in turn drives the adjustment seat to move on the top of the worktable, increasing the structural strength and ensuring stability.

[0010] Preferably, it also includes two sets of limiting guide rods. The limiting guide rods are symmetrically installed at the left and right ends of the adjusting seat, and the limiting guide rods are slidably installed on the inner wall of the upright leg. When the adjusting seat moves back and forth, it drives the limiting guide rods to slide on the inner wall of the upright leg to guide and limit them, so as to ensure stability.

[0011] Preferably, the support components include multiple upright legs, multiple threaded support rods, and multiple connecting rods. The multiple upright legs are evenly installed at the four corners of the bottom of the workbench. Threaded support rods are screwed onto the bottom of the upright legs, and friction plates are provided at the bottom of the threaded support rods. Connecting rods are installed between two adjacent upright legs. The bottom of the equipment is supported by the multiple upright legs. The equipment is installed at the rear end of the pipe cooling tank. Rotating the threaded support rods can adjust the equipment to be level. The connecting rods increase the connection strength and ensure stability.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: the bottom of the workbench is supported by the support component, which is installed at the rear end of the pipe cooling tank. After the PVC pipe is extruded and cooled, it enters between the support conveying component and the pressing component. The PVC pipe is pulled by the traction component.
