Description

Technical Field

[0001] This utility model relates to the field of PVC board production technology, specifically to a traction device for anti-torsion PVC board molding. Background Technology

[0002] PVC sheets are used for surface packaging of various panels, hence they are also known as decorative film or adhesive film. They are used in many industries such as building materials, packaging, and pharmaceuticals, with the building materials industry accounting for the largest share at 60%, followed by the packaging industry, and several other smaller-scale applications. Based on hardness, they can be divided into soft PVC and rigid PVC; based on manufacturing process, they can be divided into PVC skinned foamed sheets and PVC free-foamed sheets; based on transparency, they can be divided into transparent PVC sheets and PVC boards.

[0003] After molding and processing, existing PVC sheets require a traction device to transport them to the next process. However, traditional traction and transmission devices for PVC sheet molding have certain drawbacks. Since the traction device does not have corresponding guide and limit components, if the PVC sheet deviates from the track on the conveyor belt, it may damage the sheet, causing it to fall and twist, affecting the subsequent processing of the entire PVC sheet and increasing production costs. Utility Model Content

[0004] The purpose of this utility model is to provide a traction device for anti-torsion PVC board molding, which solves the problem that the existing traction device does not have corresponding guide and limiting components, and the PVC board may be damaged when it deviates from the track on the conveyor belt.

[0005] To achieve the above objectives, a traction device for forming anti-twist PVC boards is provided, including a traction frame, a guide plate fixedly connected to one outer end of the traction frame, a motor fixedly connected to one outer end of the traction frame, a conveying roller disposed through the output end of the motor, a pulley fixedly connected to the shaft of the conveying roller, and belts sleeved on the pulleys of two adjacent conveying rollers.

[0006] Both ends of the inner side of the traction frame are equipped with movable frames, and several guide rollers are rotatably connected inside the movable frames.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4 This utility model provides a technical solution: a traction device for anti-twist PVC board molding, including a traction frame 6. A guide plate 1 is fixedly connected to one outer end of the traction frame 6. The guide plate 1 can guide the PVC board and make it stably enter the traction equipment. A motor 2 is fixedly connected to one outer end of the traction frame 6. The output end of the motor 2 passes through the traction frame 6 and is provided with a conveying roller 17. A pulley is fixedly connected to the rotating shaft of the conveying roller 17, and a belt 18 is sleeved on the pulleys of two adjacent conveying rollers 17. By starting the motor 2, the conveying roller 17 and the pulley can be driven to rotate. At the same time, under the transmission of the belt 18, the stable conveying and traction operation of the conveying roller 17 can be realized.

[0024] Both ends of the inner side of the traction frame 6 are equipped with movable frames 9. Several guide rollers 10 are rotatably connected inside the movable frame 9. The guide rollers 10 can stably guide both ends of the PVC board, which can prevent the PVC board from twisting and shifting during the traction process, and also avoid the risk of the board falling off the traction equipment.

[0025] A connecting frame 5 is fixedly connected to one lower end of the traction frame 6. A motor 4 is fixedly connected to the outer end of the connecting frame 5. A screw 13 is provided inward through the output end of the motor 4 through the connecting frame 5. Two threaded blocks 11 are threadedly connected to the screw 13, and the internal threads of the threaded blocks 11 are arranged in opposite directions. A slot 12 is opened inside the connecting frame 5. The threaded blocks 11 are fixedly connected to the movable frame 9 through the slot 12. Starting the motor 4 can drive the screw 13 to rotate. Under the action of the threaded connection, the two threaded blocks 11 can move relative to each other, which drives the two movable frames 9 to move relative to each other, thereby adjusting their distance. This ensures that the guide rollers 10 inside the movable frame 9 can contact the two ends of the plate. The guide rollers 10 can limit and guide the plate, improve the traction effect of the entire traction equipment, and also prevent the plate from shifting or twisting during the traction process.

[0026] A connecting frame 2 7 is fixedly connected to the other end of the lower part of the traction frame 6. A sliding groove 15 is opened inside the connecting frame 2 7. A sliding rod 16 is fixedly connected inside the sliding groove 15. A slider 14 is slidably connected on the sliding rod 16. The slider 14 passes through the sliding groove 15 and is fixedly connected to the other end of the movable frame 9. By setting the slider 14 and the sliding rod 16, the movable frame 9 can be restricted to ensure the stability of the movable frame 9 when it moves.

[0027] The inner side of the traction frame 6 is fixedly connected to the other end of the guide plate 2 8, and the four ends of the lower part of the traction frame 6 are fixedly connected to the bracket 3. The PVC board can be transported to other equipment for processing through the guide plate 2 8, while the bracket 3 below can provide stable support for the device and improve the stability of the device.

[0028] Working principle: During use, the guide plate 1 is aligned with the discharge end of the molding equipment. The starting motor 2 drives the internal guide roller 10 and pulley to rotate. Under the interaction of the pulley and belt, the multiple guide rollers inside rotate synchronously, completing the traction of the PVC board. In order to prevent the board from shifting or twisting during the traction process, the starting motor 4 drives the screw 13 to rotate. Under the action of the threaded connection, the two threaded blocks 11 move relative to each other, driving the two movable frames 9 to move relative to each other, thereby adjusting their spacing. This ensures that the guide roller 10 inside the movable frame 9 can contact the two ends of the board. The guide roller 10 can limit and guide the board, improve the traction effect of the entire traction equipment, and also prevent the board from shifting or twisting during the traction process.

[0029] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
