Description

Technical Field

[0001] This utility model belongs to the field of plastic processing technology, and specifically relates to a traction roller assembly structure with anti-slip texture on the surface. Background Technology

[0002] PVC film is made of polyvinyl chloride resin and other modifiers through calendering or blow molding. Plasticizers, stabilizers, lubricants and other functional processing aids are added to the PVC resin and then calendered into a film. This type of greenhouse film has good heat preservation and light transmission, is soft and easy to shape, and is suitable as an outer covering material for greenhouses, sheds and small and medium-sized sheds.

[0003] Traditional traction roller assembly structures are prone to uneven adjustment on both sides, leading to roller misalignment, which affects the stability of material conveying. The smooth surface makes it easy for materials to slip, and the spacing adjustment relies on manually adjusting each bolt one by one, making it difficult to ensure parallelism. At the same time, unstable traction pressure can damage materials, requiring frequent pressure adjustments and making it difficult to maintain a constant traction effect, which can easily affect the continuity of production.

[0004] To address the problems mentioned in the background, a traction roller assembly structure with anti-slip texture on the surface is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a traction roller assembly structure with anti-slip texture on the surface, which has the advantages of synchronous adjustment and stable traction force.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a traction roller assembly structure with anti-slip texture on the surface, including a shell, support plates are bolted to the top of the shell on both sides away from the middle, a rotating rod is inserted through and rotatably sleeved on the left side of the support plate on the right side, a vertical bevel gear is fixedly sleeved on the middle and left side of the rotating rod surface, a horizontal bevel gear is meshed with the bottom of the vertical bevel gear, a screw is fixedly sleeved inside the horizontal bevel gear, and the top of the screw surface penetrates through the top of the shell near the middle on both sides and is rotatably sleeved, slots are opened on the top of both sides of the inner wall of the shell, and the bottom of the screw is rotatably connected to the bottom of the slot, a threaded sleeve is threaded to the bottom of the screw surface, a connecting plate is bolted to the opposite side of the two threaded sleeves, and a buffer mechanism is provided on both sides of the bottom of the connecting plate.

[0007] Using the above technical solution: When it is necessary to adjust the distance between traction roller one and traction roller two, the turntable rotates, causing the rotating rod to rotate. The rotating rod drives the bevel gear to rotate, the vertical bevel gear drives the horizontal bevel gear to rotate, the horizontal bevel gear drives the screw to rotate, the screw rotates, causing the screw sleeve to move, the screw sleeve moves, causing the connecting plate to move, the connecting plate moves, causing the trough box to move, and the trough box moves, causing the rotating shaft one and traction roller one to move. The screw and screw sleeve realize the synchronous adjustment of the distance between the upper and lower rollers. The linkage mechanism on both sides ensures that the rollers move in parallel without deviation. The anti-slip texture on the surface can effectively increase the friction to prevent the material from slipping. The mechanical adjustment structure is simple and reliable, and the roller distance can be accurately controlled without additional power. It is particularly suitable for industrial scenarios that require frequent pressure adjustments or adaptation to materials of different thicknesses.

[0008] The present invention is further configured such that the buffer mechanism includes a slot box, the slot box is bolted to both sides of the bottom of the connecting plate, a sliding groove is provided on the opposite side of the two slot boxes, a slider is slidably connected inside the sliding groove, a spring is bolted to the top of the slider, and the end of the spring away from the slider is bolted to the top inside the sliding groove, a rotating shaft is rotatably connected to the opposite side of the two sliders, a traction roller is fixedly sleeved on the surface of the rotating shaft, and an active traction mechanism is provided at the bottom of the left side of the inner wall of the outer shell.

[0009] The above technical solution employs a buffer mechanism. During the traction process, after the PVC film is shaped by the cooling roller, it passes between traction roller one and traction roller two. The winding force during the winding process may fluctuate. At this time, the PVC film applies an upward force to traction roller one. This upward force causes traction roller one to move, which in turn moves slider one. Slide 2 limits the movement of slider two. Slide two's upward movement compresses the spring, causing it to contract. When the winding force recovers, the spring rebounds, causing slider two to return to its original position. Slide two then moves traction roller one and traction roller one back to their original positions. This effectively absorbs vibrations caused by material thickness fluctuations or foreign object impacts. The elastic deformation of the spring allows the upper roller to automatically fine-tune its height, maintaining constant pressure on the material. The anti-slip textured surface ensures stable traction force and prevents slippage. It is particularly suitable for handling soft materials. The overall structure is simple and reliable, achieving adaptive adjustment without a complex control system.

[0010] The present invention is further configured such that the active traction mechanism includes a motor, the motor is embedded in the bottom of the left side of the inner wall of the outer casing, a second rotating shaft is fixedly sleeved on the right side of the motor, and the right side of the second rotating shaft is rotatably connected to the bottom of the right side of the inner wall of the outer casing, and a second traction roller is fixedly sleeved on the surface of the second rotating shaft.

[0011] The above technical solution involves setting up an active traction mechanism. The motor drives the second rotating shaft to rotate, and the second rotating shaft drives the second traction roller to rotate, which can actively traction the PVC film.

[0012] The present invention is further configured such that a slider is bolted to the opposite side of the two screw sleeves, and a sliding groove is formed on the opposite side of the two slots, and the interior of the sliding groove is slidably connected to the surface of the slider.

[0013] The above technical solution, by setting slider one and slide groove one, can limit the movement of the screw sleeve.

[0014] The present invention is further configured such that a damper is sleeved inside the spring.

[0015] The above technical solution involves setting a damper to limit the spring and prevent it from continuously rebounding.

[0016] The present invention is further provided that the surfaces of the first traction roller and the second traction roller are provided with anti-slip texture.

[0017] The above technical solution, by setting anti-slip texture, can prevent the PVC film from slipping and shifting during the traction process.

[0018] The present invention is further configured such that a turntable is fixedly sleeved on the right side of the rotating rod.

[0019] The above technical solution involves setting up a turntable, which allows for easy rotation of the rotating rod.

[0020] The present invention is further configured such that a bearing is rotatably connected to the left side of the rotating rod.

[0021] The above technical solution, by incorporating bearings, can stabilize the rotating rod.

After the film is shaped by the cooling roller, it passes between traction roller 18 and traction roller 2. During the winding process of the winding mechanism, the winding force may fluctuate. At this time, the PVC film applies an upward force to traction roller 18. After receiving the upward force, traction roller 18 drives the rotating shaft 16 to move. The movement of rotating shaft 16 drives slider 2 13 to move. Slide groove 2 14 limits the movement of slider 2 13. Sliding slider 2 13 moves upward and squeezes spring 15, causing spring 15 to contract. When the winding force recovers, spring 15 rebounds and drives slider 2 13 to return to its original position. Sliding slider 2 13 drives rotating shaft 16 and traction roller 18 to return to their original positions. This can effectively absorb the vibration caused by material thickness fluctuations or foreign object impacts.

[0040] refer to Figure 1 The surfaces of traction roller 18 and traction roller 29 are provided with anti-slip texture 22. By providing anti-slip texture 22, the PVC film can be prevented from slipping and shifting during the traction process.

[0041] Brief description of the usage process: During the traction process of the mechanism, after the PVC film is shaped by the cooling roller, it passes between the traction roller 18 and the traction roller 2. During the winding process of the winding mechanism, the winding force may fluctuate. At this time, the PVC film applies an upward force to the traction roller 18. After the traction roller 18 receives the upward force, it drives the rotating shaft 16 to move. The movement of the rotating shaft 16 drives the slider 2 13 to move. The slide groove 2 14 limits the movement of the slider 2 13. The upward movement of the slider 2 13 compresses the spring 15, causing the spring 15 to contract. The damper 21 limits the spring 15 and prevents the spring 15 from continuously rebounding. When the winding force is restored, the spring 15 rebounds and drives the slider 2 13 to return to its position. The slider 2 13 drives the rotating shaft 16 and the traction roller 18 to return to their positions. It can effectively absorb the vibration caused by material thickness fluctuations or foreign object impacts.
