Abstract
Description
Technical Field
[0001] This utility model relates to the field of film forming technology, and in particular to a film forming mechanism for PE film. Background Technology
[0002] During the molding process of PE film, it is necessary to press the PE film into shape. Most existing pressing equipment for PE film adopts roller pressing, which is to move the PE film between two sets of rotating rollers by bringing them close together. The pressing of the PE film is completed by the two sets of rollers.
[0003] However, in the existing PE film pressing process, there is no limiting function when the PE film moves between the two sets of rollers. Therefore, when the PE film deviates slightly, the edge of the subsequent winding will tilt, affecting the winding effect after forming. To address this issue, we propose a PE film pressing and forming mechanism. Utility Model Content
[0004] The purpose of this utility model is to address the shortcomings of existing technologies mentioned in the background section by proposing a PE film pressing and forming mechanism.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: A PE film compression molding mechanism includes a support base, support frames on both sides of the top of the support base, a connecting shaft on the side of the support frame, a connecting frame at the end of the connecting shaft, a compression roller at the top of the connecting frame, a roller shaft on the side wall of the support frame, an mounting rod at the top of the support frame, a connecting sleeve sleeved on the outside of the mounting rod, a rotating sleeve sleeved on the outside of the connecting sleeve, a connecting rod at the end of the rotating sleeve, and a limiting plate at the bottom of the connecting rod. The limiting plate is arc-shaped and its end is adapted to the outside of the roller shaft. The connecting sleeve can drive the limiting plate to slide, thereby allowing the limiting plate to move outside the roller shaft. This allows the limiting plate to limit both sides of the PE film, resulting in better winding of the PE film.
[0006] Preferably, an adjusting shaft is sleeved at the middle position of the bottom end of the connecting frame, a connecting plate is provided at the bottom end of the adjusting shaft, a first servo motor is provided on the front side of the supporting floor, a threaded adjusting rod is provided at the output end of the first servo motor, and the connecting plate is sleeved on the outside of the threaded adjusting rod. The first servo motor can drive the threaded adjusting rod to rotate, thereby causing the adjusting shaft to drive the connecting frame to rotate. This allows the extrusion roller and the roller shaft to move closer to each other and separate, thus facilitating the pressing or separation of the PE film.
[0007] Preferably, a second servo motor is provided on the side wall of the support frame, and a rotating rod is provided at the output end of the second servo motor. The rotating rod extends into the interior of the support frame. A moving rod is inserted on the other side of the support frame. The end of the rotating rod extends into the interior of the moving rod. The rotating rod is hexagonal in shape. A support plate is provided at the end of the moving rod. A hexagonal protrusion is provided at the end of the support plate. The protrusion extends to the end of the roller. The second servo motor can drive the rotating rod to rotate, thereby allowing the support plate to drive the roller to rotate, completing the film pressing and winding process.
[0008] Preferably, a support spring is provided inside the movable rod, one end of the support spring is fixedly connected to the rotating rod, and the other end of the support spring is fixedly connected to the inner wall of the movable rod; The support plate can be supported by a support spring, which in turn supports the roller shaft, allowing the roller shaft to be disassembled and installed.
[0009] Preferably, an adjusting screw is inserted inside the mounting rod, a movable sleeve is sleeved on the outside of the adjusting screw, a connecting block is provided on the outside of the movable sleeve, and the end of the connecting block penetrates the inner wall of the mounting rod and is fixedly connected to the inner wall of the connecting sleeve. The moving screw sleeve can be moved by rotating the adjusting screw, which in turn drives the connecting sleeve to move through the connecting block, making the movement of the connecting sleeve more convenient.
[0010] Preferably, a groove is provided at the position of the connecting sleeve, and the rotating sleeve can rotate outside the connecting sleeve; The rotating sleeve can drive the connecting rod and the limiting plate to rotate, so that the limiting plate can be separated on the roller shaft, making it convenient to disassemble the PE film after winding.
[0011] Preferably, one end of the adjusting screw extends through the mounting rod to the outside, and a rotating disk is provided at the end of the adjusting screw located to the outside, and a crank is provided at the eccentric shaft position of the rotating disk; The operator can turn the crank to rotate the rotating disc, which in turn drives the adjusting screw to rotate, making the adjustment screw rotation more convenient.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model can move the movable screw sleeve by rotating the adjusting screw, and the movable screw sleeve moves the connecting sleeve through the connecting block, thereby causing the connecting sleeve to move the rotating sleeve and the limiting plate outside the roller shaft. This allows the limiting plate to move to both sides of the PE film for limiting, preventing the PE film from shifting during the winding process.
[0013] 2. This utility model allows the support spring to support the support plate, thereby extending the end of the support plate into the interior of the roller shaft to support the roller shaft. At the same time, the second servo motor can drive the moving rod and the support plate to rotate through the rotating rod, so that the roller shaft can rotate normally. Meanwhile, the support plate can move laterally until it detaches from the end of the roller shaft, which facilitates the disassembly and installation of the roller shaft. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0017] Reference Figure 1-4The illustrated PE film compression molding mechanism has support frames 2 on both sides of the top of a support base 1. A connecting shaft 3 is located in the middle of the support frame 2, and a connecting frame 4 is movably mounted at the end of the connecting shaft 3. The connecting frame 4 is U-shaped, and a compression roller 5 is movably mounted at the top of the connecting frame 4. An adjusting shaft 6 is sleeved at the middle of the bottom end of the connecting frame 4, and a connecting plate 8 is movably mounted at the bottom end of the adjusting shaft 6. A first servo motor 9 is located at the top of the support base 1, and a threaded adjusting rod 7 is fixedly mounted at the output end of the first servo motor 9. The connecting plate 8 is sleeved on the outside of the threaded adjusting rod 7. Subsequently, a roller 10 is movably mounted on the front of the support frame 2. One end of the roller 10 has a hexagonal slot. A second servo motor is fixedly mounted on the side of the support frame 2. The machine 11 is then fixedly installed with a rotating rod 12 at the output end of the second servo motor 11. The support frame 2 has a slot inside, and the rotating rod 12 extends into the slot. Then, a moving rod 13 is inserted on the other side of the support frame 2. The end of the moving rod 13 also extends into the slot of the support frame 2. The end of the moving rod 13 has a slot that matches the rotating rod 12, so that the end of the rotating rod 12 extends into the moving rod 13. Then, a support spring 15 is fixedly installed inside the moving rod 13. One end of the support spring 15 is fixedly connected to the rotating rod 12, and the other end of the support spring 15 is fixedly connected to the inner wall of the moving rod 13. The end of the support plate 14 is provided with a hexagonal protrusion that matches the groove at the end of the roller 10.
[0018] For a detailed description of the mounting rod 16 in this embodiment, please refer to [link / reference]. Figure 3 and Figure 4 Then, an installation rod 16 is fixedly installed at the top of the support frame 2. An adjusting screw 18 is inserted into the end of the installation rod 16. The adjusting screw 18 extends into the interior of the installation rod 16, and a movable screw sleeve 19 is sleeved on the outside of the adjusting screw 18. Connecting blocks 20 are fixedly installed around the outer wall of the movable screw sleeve 19. A connecting sleeve 17 is sleeved on the outside of the installation rod 16. The end of the connecting block 20 passes through the inner wall of the installation rod 16 and the connecting sleeve 17. An annular groove is opened in the middle of the connecting sleeve 17, and a rotating sleeve 21 is sleeved in the middle of the connecting sleeve 17. A connecting rod 22 is fixedly installed at the bottom of the rotating sleeve 21. Then, a limiting plate 23 is fixedly installed at the bottom of the connecting rod 22. The limiting plate 23 is arc-shaped and fits against the outer wall of the roller shaft 10. Then, a rotating disk 24 is fixedly installed at the end of the adjusting screw 18 that extends to the outside of the installation rod 16.
[0019] Working Principle: When in use, this device can be powered by an external power source to start the first servo motor 9. The first servo motor 9 drives the threaded adjusting rod 7 to rotate, which in turn moves the connecting plate 8. This causes the connecting plate 8 to move the adjusting shaft 6 and the connecting frame 4, which in turn moves the extrusion roller 5. The extrusion roller 5 then adheres to the outer wall of the roller shaft 10, allowing the PE film to be rolled and formed between the extrusion roller 5 and the roller shaft 10. Simultaneously, the rotating disk 24 can be rotated, causing the adjusting screw 18 to rotate. The adjusting screw 18 moves the moving screw sleeve 19, which in turn moves the connecting block 20 and the connecting sleeve 17. The connecting sleeve 17 then moves the rotating sleeve 21 and the connecting rod 22. The connecting rod 22 moves the limiting plate 23 outside the roller shaft 10, allowing the limiting plate 23 to limit the two sides of the PE film, thus improving the PE film winding effect.
[0020] The operator manually slides the support plate 14 so that the end of the support plate 14 is disengaged from the inside of the roller 10. Then, the roller 10 is removed and a new roller 10 is placed on the side wall of the support frame 2. Then, the other end of the roller 10 is placed in the position of the support plate 14. At this time, the support plate 14 is released so that the support spring 15 drives the support plate 14 to be inserted into the end of the roller 10 to complete the connection. Then, the second servo motor 11 drives the rotating rod 12 to rotate, and the rotating rod 12 drives the moving rod 13 and the support plate 14 to rotate. The support plate 14 drives the roller 10 to rotate, so that the roller 10 can continue to complete the PE film winding work.
