Technical Field
[0001] This utility model relates to the field of plastic processing technology, and in particular to a ton bag plastic extrusion laminating machine with a winding mechanism. Background Technology
[0002] In the production of ton-bag plastics, the extrusion laminating machine is a key piece of equipment for realizing plastic extrusion molding and completing the lamination process. Among these, the winding mechanism, as an important component of the extrusion laminating machine, directly affects the production efficiency and finished product quality of ton-bag plastics. Existing ton-bag plastic extrusion laminating machine winding mechanisms have several problems: First, the tension adjustment method of the transmission belt is cumbersome and lacks precision, easily leading to slippage after prolonged use, resulting in unstable power transmission and reduced equipment operating efficiency; second, the installation and disassembly of the winding drum is inconvenient, making it difficult to quickly replace winding drums of different specifications, failing to meet diverse production needs; third, before lamination enters the winding process, there is a lack of effective leveling treatment devices, easily resulting in wrinkles, unevenness, and other defects, affecting the appearance and performance of the finished ton-bag plastic products.
[0003] Regarding the above and existing related technologies, the inventor believes that the following defects often exist: the existing ton bag plastic extrusion laminating machine winding mechanism has a cumbersome transmission belt tension adjustment method and low adjustment accuracy. After long-term use, it is prone to slippage, resulting in unstable power transmission and reduced equipment operating efficiency. Therefore, in order to solve the above problems, a ton bag plastic extrusion laminating machine with a winding mechanism is proposed. Summary of the Invention
[0004] The purpose of this utility model is to solve the problems of existing ton bag plastic extrusion laminating machines, such as the cumbersome and inaccurate adjustment of the transmission belt tension in the winding mechanism, which is prone to slippage after long-term use, resulting in unstable power transmission and reduced equipment operating efficiency. Therefore, this utility model proposes a ton bag plastic extrusion laminating machine with a winding mechanism.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a ton bag plastic extrusion laminating machine with a winding mechanism, comprising a base, a laminating machine body mounted on the surface of the base, a first winding plate fixedly connected to the surface of the base, a bearing ring sleeved inside the first winding plate, a first mounting post fixedly connected to one side of the bearing ring, two sliding grooves formed on the surface of the base, a sliding seat slidably connected to the inner wall of the sliding grooves, a second winding plate fixedly connected to the surface of the sliding seat, a second mounting post inserted through the second winding plate, a large driven wheel fixedly connected to the side of the second mounting post away from the first winding plate, a motor fixedly mounted on one side of the sliding seat, a small driven wheel fixedly connected to the output end of the motor, a transmission belt drivingly connecting the surfaces of the large driven wheel and the small driven wheel, clamping sleeves engaged on the surfaces of both the first and second mounting posts, a cylinder fixedly mounted on the surface of the base, one end of the cylinder fixedly connected to the sliding seat.
[0006] The aforementioned components achieve the following effects: by driving the sliding seat along the slide groove via a cylinder, the distance between the first and second take-up plates can be flexibly adjusted to precisely adapt to take-up drums of different sizes. At the same time, the motor drives the large driven wheel and the second mounting column to rotate via the small driven wheel and the transmission belt. In conjunction with the bearing ring of the first mounting column, synchronous winding operation at two stations is achieved, significantly improving the winding efficiency of ton-bag plastic film coating.
[0007] Preferably, a support plate is fixedly connected to one side of the second winding plate, an adjusting plate is slidably inserted into the support plate, a U-shaped plate is fixedly connected to one side of the adjusting plate, an elliptical plate is fixedly connected to one side of the adjusting plate, an adjusting groove is formed on the surface of the adjusting plate, a sliding rod is slidably inserted into the support plate, a pull plate is fixedly connected to one end of the sliding rod, the size of the sliding rod is adapted to the size of the adjusting groove of the adjusting plate, and the U-shaped plate abuts against the surface of the transmission.
[0008] The effects achieved by the above components are as follows: through the cooperation of components such as adjusting plate, U-shaped plate, elliptical plate, sliding rod and pull plate, the tension of the transmission belt can be easily adjusted, which can effectively avoid problems such as slippage and power transmission failure caused by the transmission belt being too loose, or accelerated wear caused by the transmission belt being too tight. It can also extend the service life of the transmission belt, ensure the stable operation of the winding mechanism, and improve the working efficiency and reliability of the equipment.
[0009] Preferably, the arc surface of the sliding rod is fitted with a first spring, and the two ends of the first spring are fixedly connected to the pull plate and the support plate, respectively.
[0010] The aforementioned components achieve the following effect: by setting a first spring, the sliding rod is automatically pushed into the adjustment slot of the adjustment plate, thus improving the practicality of the device.
[0011] Preferably, a fixing rod is fixedly connected to the inner wall of the U-shaped plate, and a rotating drum is rotatably connected to the arc surface of the fixing rod, with the rotating drum abutting against the surface of the transmission belt.
[0012] The effects achieved by the above components are as follows: the drum can rotate synchronously with the transmission belt, replacing sliding friction with rolling friction, which greatly reduces the wear on the transmission belt surface. At the same time, the drum closely abuts against the transmission belt, which can evenly distribute and adjust the pressure, avoid excessive local stress, make the transmission belt more evenly stressed, ensure the stability of the transmission belt tension, effectively extend the service life of the transmission belt, and improve the stability and reliability of equipment operation.
[0013] Preferably, the first mounting post and the second mounting post each have two grooves on their arc surfaces. A second spring is fixedly connected to the inner wall of the groove. One end of the second spring is fixedly connected to a locking rod. The arc surface of the clamping cylinder has two fixing slots. The size of the locking rod is adapted to the size of the fixing slots of the clamping cylinder.
[0014] The aforementioned components achieve the following effects: by utilizing the elastic deformation of the second spring, the locking rod and the retaining groove of the retaining tube are automatically engaged and disengaged. When installing the retaining tube, the locking rod is compressed and retracts into the groove. After aligning with the retaining groove, the second spring pushes the locking rod to quickly embed and securely lock the retaining tube. When disassembling, only external force needs to be applied to compress the second spring to retract the locking rod, and the retaining tube can be easily removed. The operation is simple and quick, requiring no additional tools. This ensures that the retaining tube is stable and does not fall off during the winding process, and allows for quick replacement of retaining tubes of different specifications according to production needs, significantly improving the flexibility and efficiency of equipment use.
[0015] Preferably, the arc surfaces of the first and second mounting posts are both fixedly connected to guide rods, and the inner wall of the clamping cylinder is provided with a guide groove.
[0016] The effect achieved by the above components is that the guide rods on the first and second mounting posts cooperate with the guide grooves on the inner wall of the clamping cylinder. When installing the clamping cylinder, the guide rods can be accurately embedded in the guide grooves, providing guidance for the installation of the clamping cylinder, avoiding offset or misalignment during installation, and ensuring that the clamping cylinder can be quickly and accurately connected with the mounting posts.
[0017] Preferably, two flat plates are fixedly connected to the surface of the base, and two rotating rollers are fixedly connected to the side of the two flat plates that are close to each other. The arc surface of the rotating rollers is coated with a heat-resistant and non-stick coating, which is a polytetrafluoroethylene propylene coating.
[0018] The effects achieved by the above components are as follows: the flat plate and the rotating roller with the polytetrafluoroethylene (PTFE) coating can effectively ensure the flatness of the ton bag plastic film lamination. The PTFE coating has excellent heat resistance and can withstand the high temperature environment during the lamination process, preventing the rotating roller from deforming or the plastic film from sticking due to high temperature. Its excellent anti-stick properties prevent the plastic film from sticking to the rotating roller, ensuring that the film passes smoothly through the rotating roller without wrinkles, stretching, or deformation.
[0019] In this invention, the sliding seat is driven by a cylinder to move along the slide groove, which can flexibly adjust the distance between the first winding plate and the second winding plate, and accurately adapt to winding drums of different sizes. At the same time, the motor drives the large driven wheel and the second mounting column to rotate through the small driven wheel and the transmission belt. In conjunction with the bearing ring of the first mounting column, the dual-station synchronous winding operation is realized, which significantly improves the winding efficiency of ton-bag plastic film coating.

[0022] Reference Figure 1-5As shown, this utility model provides a technical solution: a ton bag plastic extrusion laminating machine with a winding mechanism, including a base 1, a laminating machine body mounted on the surface of the base 1, a first winding plate 3 fixedly connected to the surface of the base 1, a bearing ring 5 sleeved inside the first winding plate 3, a first mounting post 6 fixedly connected to one side of the bearing ring 5, two sliding grooves opened on the surface of the base 1, a sliding seat 4 slidably connected to the inner wall of the sliding groove of the base 1, a second winding plate 21 fixedly connected to the surface of the sliding seat 4, a second mounting post 11 inserted through the second winding plate 21, a large driven wheel 10 fixedly connected to the side of the second mounting post 11 away from the first winding plate 3, a motor 8 fixedly mounted on one side of the sliding seat 4, a small driven wheel 29 fixedly connected to the output end of the motor 8, a transmission belt 9 drivingly connected to the surfaces of the large driven wheel 10 and the small driven wheel 29, a clamping sleeve 22 being engaged on the surfaces of the first mounting post 6 and the second mounting post 11, a cylinder 7 fixedly mounted on the surface of the base 1, one end of the cylinder 7 being fixedly connected to the sliding seat 4. The cylinder 7 drives the sliding seat 4 to move along the slide groove, which can flexibly adjust the distance between the first winding plate 3 and the second winding plate 21 to accurately adapt to winding drums of different sizes. At the same time, the motor 8 drives the large driven wheel 10 and the second mounting column 11 to rotate through the small driven wheel 29 and the transmission belt 9. With the bearing ring 5 of the first mounting column 6, the dual-station synchronous winding operation is realized, which significantly improves the winding efficiency of ton-bag plastic film coating. A support plate 12 is fixedly connected to one side of the second winding plate 21. An adjusting plate 13 is slidably inserted in the support plate 12. A U-shaped plate 18 is fixedly connected to one side of the adjusting plate 13. An elliptical plate 14 is fixedly connected to one side of the adjusting plate 13. An adjusting groove is opened on the surface of the adjusting plate 13. A sliding rod 15 is slidably inserted in the support plate 12. A pull plate 16 is fixedly connected to one end of the sliding rod 15. The size of the sliding rod 15 is adapted to the size of the adjusting groove of the adjusting plate 13. The U-shaped plate 18 abuts against the surface of the transmission. The tension of the transmission belt 9 can be easily adjusted by the cooperation of components such as adjusting plate 13, U-shaped plate 18, elliptical plate 14, sliding rod 15, and pull plate 16. This effectively avoids problems such as slippage and power transmission failure caused by the transmission belt 9 being too loose, or accelerated wear caused by it being too tight. It also extends the service life of the transmission belt 9, ensures stable operation of the winding mechanism, and improves the working efficiency and reliability of the equipment. The arc surface of the sliding rod 15 is fitted with a first spring 17, and the two ends of the first spring 17 are fixedly connected to the pull plate 16 and the support plate 12, respectively. By setting the first spring 17, the sliding rod 15 is automatically sprung into the adjusting groove of the adjusting plate 13, which improves the practicality of the device. The inner wall of the U-shaped plate 18 is fixedly connected to a fixing rod 19, and the arc surface of the fixing rod 19 is rotatably connected to a rotating drum 20, which abuts against the surface of the transmission belt 9.The rotating drum 20 can rotate synchronously with the transmission belt 9, replacing sliding friction with rolling friction, which greatly reduces the wear on the surface of the transmission belt 9. At the same time, the rotating drum 20 closely abuts against the transmission belt 9, which can evenly distribute and adjust the pressure, avoid excessive local force, make the transmission belt 9 more evenly stressed, ensure the stability of the tension of the transmission belt 9, effectively extend the service life of the transmission belt 9, and improve the stability and reliability of the equipment operation. The first mounting column 6 and the second mounting column 11 each have two grooves on their arc surfaces. The inner wall of the groove is fixedly connected to the second spring 23. One end of the second spring 23 is fixedly connected to the locking rod 24. The arc surface of the locking cylinder 22 has two fixing slots. The size of the locking rod 24 is adapted to the size of the fixing slot of the locking cylinder 22. The second spring 23 utilizes its elastic deformation to automatically engage and disengage the locking rod 24 from the fixing groove of the clamping cylinder 22. When installing the clamping cylinder 22, the locking rod 24 is compressed and retracts into the groove. After aligning with the fixing groove, the second spring 23 pushes the locking rod 24 to quickly embed and securely lock the clamping cylinder 22. When disassembling, only external force needs to be applied to compress the second spring 23 to retract the locking rod 24, and the clamping cylinder 22 can be easily removed. The operation is simple and quick, requiring no additional tools. This ensures that the clamping cylinder 22 is stable and does not fall off during the winding process, and allows for quick replacement of clamping cylinders 22 of different specifications according to production needs, significantly improving the flexibility and efficiency of equipment use. The arc surfaces of the first mounting column 6 and the second mounting column 11 are both fixedly connected to guide rods 25, and the inner wall of the clamping cylinder 22 is provided with guide grooves. The guide rods 25 on the first mounting post 6 and the second mounting post 11 cooperate with the guide groove on the inner wall of the clamping cylinder 22. When installing the clamping cylinder 22, the guide rods 25 can be accurately embedded in the guide groove, providing guidance for the installation of the clamping cylinder 22, avoiding offset or misalignment during installation, and ensuring that the clamping cylinder 22 can quickly and accurately align with the mounting post. Two flat plates 26 are fixedly connected to the surface of the base 1. Two rotating rollers 27 are fixedly connected to the side of the two flat plates 26 that are close to each other. The arc surface of the rotating rollers 27 is coated with a heat-resistant and non-stick coating 28, which is a polytetrafluoroethylene propylene coating. The flat plate 26 and the rotating roller 27 with the polytetrafluoroethylene (PTFE) coating can effectively ensure the flatness of the plastic film lamination of the ton bag. The PTFE coating has excellent heat resistance and can withstand the high temperature environment during the lamination process, preventing the rotating roller 27 from deforming or sticking to the plastic film due to high temperature. Its excellent anti-stick properties prevent the plastic film from sticking to the rotating roller 27, ensuring that the film can pass smoothly through the rotating roller 27 without wrinkles, stretching, or deformation.
[0023] Working principle: First, adjust the distance between the first take-up plate 3 and the second take-up plate 21 according to the size of the plastic film. When the distance needs to be adjusted, start the cylinder 7. Driven by the cylinder 7, the sliding seat 4 slides in the groove. After the position of the second take-up plate 21 is adjusted, close the cylinder 7. Then install the clamping cylinder 22 and align it with the first or second mounting post 11. The guide rod 25 is embedded in the guide groove on the inner wall of the clamping cylinder 22, which plays a precise guiding role. As the clamping cylinder 22 is pushed forward, the clamping rod 24 is squeezed back into the groove. When the clamping rod 24 is aligned with the fixing groove of the clamping cylinder 22, the second spring 23 pushes the clamping rod 24 to quickly embed into the fixing groove, completing the stable installation. Before entering the winding process, the ton bag plastic film is coated with polytetrafluoroethylene propylene between the unfolding plates 26. The rotating roller 27, with its excellent heat resistance, withstands the high temperatures during the lamination process, preventing deformation or adhesion of the plastic film. The plastic film passing through the rotating roller 27 is fixed to the clamping sleeve 22. Then, the motor 8 is started. After the motor 8 starts, the small driven wheel 29 rotates, driving the large driven wheel 10 and the second mounting post 11 to rotate via the transmission belt 9. At the same time, the first mounting post 6 rotates flexibly with the help of the bearing ring 5. The two work together to achieve synchronous winding at two stations. When the transmission belt 9 needs to be adjusted, pulling the pull plate 16 causes the sliding rod 15 to slide in the adjustment groove, driving the adjustment plate 13 to move. The U-shaped plate 18 and the elliptical plate 14 change positions accordingly. The U-shaped plate 18 increases the pressure on the transmission belt 9. After the adjustment is completed, the first spring 17 on the sliding rod 15... The sliding rod 15 is automatically snapped into the appropriate position in the adjustment groove and fixed to ensure stable adjustment. During this process, the rotating drum 20 on the inner wall of the U-shaped plate 18 rotates synchronously with the transmission belt 9, replacing sliding friction with rolling friction, reducing wear on the transmission belt 9, evenly distributing pressure, and maintaining a stable tension state of the transmission belt 9.
