Description

Technical Field

[0001] This utility model relates to the field of film pressing device technology, specifically to a wrinkle-resistant film pressing device for heat shrink film production. Background Technology

[0002] Heat shrink film is used in the sale and transportation of various products, its main function being to stabilize, cover, and protect the products. Shrink film must have high puncture resistance, good shrinkage, and a certain amount of shrinkage stress. During the shrinkage process, the film must not develop holes. Since shrink film is often used outdoors, UV stabilizers are added. The surface of the heat shrink film is hot after production, necessitating a winding process using a film-pressing device.

[0003] First, existing devices typically employ a fixed design for adjusting the distance between the auxiliary roller and the support roller. This means that heat shrink films of different thicknesses may not receive optimal support and guidance during transport. Since the thickness of the heat shrink film may vary depending on production requirements, a fixed distance between the auxiliary roller and the support roller may not be able to adapt to these changes, leading to wrinkles or uneven stretching of the heat shrink film during transport. Second, existing devices also lack an effective adjustment mechanism for adjusting the distance between the flattening roller and the heat shrink film. The main function of the flattening roller is to flatten the heat shrink film to eliminate wrinkles on its surface. However, if the distance between the flattening roller and the heat shrink film is not appropriate, the flattening effect may be greatly reduced. Too close a distance may cause the heat shrink film to be subjected to excessive pressure and deform, while too far a distance may greatly reduce the effectiveness of the flattening roller. Utility Model Content

[0004] The purpose of this invention is to provide a wrinkle-resistant pressing device for heat shrink film production, addressing the issues raised in the background art regarding the distance adjustment between the auxiliary roller and the support roller. Existing devices typically employ a fixed design, meaning that heat shrink films of different thicknesses may not receive optimal support and guidance during transport. Since the thickness of the heat shrink film may vary depending on production requirements, a fixed distance between the auxiliary roller and the support roller may not be able to adapt to these changes, leading to wrinkles or uneven stretching of the heat shrink film during transport. Similarly, existing devices lack an effective adjustment mechanism for the distance between the flattening roller and the heat shrink film. The main function of the flattening roller is to flatten the heat shrink film to eliminate wrinkles on its surface. However, if the distance between the flattening roller and the heat shrink film is inappropriate, the flattening effect may be significantly reduced. Too close a distance may cause the heat shrink film to be subjected to excessive pressure and deform, while too far a distance may significantly reduce the effectiveness of the flattening roller.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a heat shrink film production anti-wrinkle pressing device, comprising a base, a housing fixedly connected to the top of the base, a support platform fixedly connected to the center of the top of the base, support rollers fixedly connected to the bottom positions on both sides of the housing, auxiliary rollers provided above the two support rollers at the bottom positions on both sides of the housing, movable channels opened at the bottom positions on both sides of the housing, a support slide plate fixedly connected to the opposite side of the two auxiliary rollers, the side of the support slide plate away from the auxiliary rollers extending into the interior of the movable channel and slidably connected to the movable channel, a fixing plate fixedly connected to the top of the two auxiliary rollers on both sides of the housing, an adjusting bolt threadedly connected to the top of the fixing plate, and the support slide plate being fixedly connected to the bottom position on both sides of the housing. A mounting platform is located at the center, and a support frame is fixedly installed at the bottom of the mounting platform. A flattening roller is fixedly installed near the bottom of the support frame. A top plate is fixedly connected to the center of the top of the housing. A box body is fixedly connected to the center of the top of the housing. A variable frequency motor is fixedly installed on one side of the box body. A main shaft is fixedly connected to the output end of one side of the variable frequency motor. One side of the main shaft extends into the interior of the box body and is fixedly connected to a longitudinal gear. An external threaded rotating rod is rotatably connected to the center of the bottom of the box body. A sleeve is fixedly connected to the center of the top of the mounting platform. One side of the external threaded rotating rod extends through the housing, the top plate, and the sleeve and into the interior of the sleeve. A horizontal gear is fixedly connected to the top of the external threaded rotating rod. A heat shrink film body is arranged between the auxiliary roller and the support roller.

[0006] Compared with the prior art, the beneficial effects of this utility model are:

[0007] This anti-wrinkle pressing device for heat shrink film production, through the design of adjusting bolts, fixing plates, support slides, movable channels, and auxiliary rollers, allows the device to adjust the distance between the auxiliary rollers and support rollers. This enables it to adapt to heat shrink films of different thicknesses and materials, ensuring optimal support and guidance during transport. This helps reduce wrinkles and uneven stretching, improving product quality. Simultaneously, the design of a variable frequency motor, longitudinal gears, transverse gears, external threaded rotating rods, sleeves, and mounting platform allows the device to adjust the distance between the flattening rollers and the heat shrink film.

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] Please see Figure 1-4This utility model provides a technical solution: a heat shrink film production anti-wrinkle pressing device, including a base 1, a housing 2 fixedly connected to the top of the base 1, a support platform 3 fixedly connected to the center of the top of the base 1, support rollers 6 fixedly connected to the bottom positions on both sides of the housing 2, auxiliary rollers 5 respectively arranged above the two support rollers 6 at the bottom positions on both sides of the housing 2, movable channels 20 opened at the bottom positions on both sides of the housing 2, support slide plates 21 fixedly connected to the opposite sides of the two auxiliary rollers 5, the side of the support slide plates 21 away from the auxiliary rollers 5 passing through the interior of the movable channels 20 and slidingly connected to the movable channels 20, fixing plates 23 fixedly connected to the top of the two auxiliary rollers 5 on both sides of the housing 2, adjusting bolts 24 threadedly connected to the top of the fixing plates 23, and an installation device is arranged at the center position inside the housing 2. The mounting platform 7 has a support frame 8 fixedly installed at its bottom. A flattening roller 9 is fixedly installed near the bottom of the support frame 8. A top plate 10 is fixedly connected to the center of the top of the housing 2. A box body 11 is fixedly connected to the center of the top of the housing 2. A variable frequency motor 12 is fixedly installed on one side of the box body 11. A main shaft 13 is fixedly connected to the output end of one side of the variable frequency motor 12. A longitudinal gear 14 is fixedly connected to one side of the main shaft 13, which extends into the interior of the box body 11. An external threaded rotating rod 16 is rotatably connected to the center of the bottom of the box body 11. A sleeve 17 is fixedly connected to the center of the top of the mounting platform 7. One side of the external threaded rotating rod 16 extends through the housing 2, the top plate 10, and the sleeve 17 and into the interior of the sleeve 17. A horizontal gear 15 is fixedly connected to the top of the external threaded rotating rod 16. A heat shrink film body 4 is provided between the auxiliary roller 5 and the support roller 6.

[0015] The active passageway 20 has two fixed support rods 22 inside. Both support rods 22 are sleeved and slidably connected to the support slide plate 21, which makes the support of the auxiliary roller 5 more stable and effectively prevents the auxiliary roller 5 from shaking or shifting due to external force during use, thereby improving the stability of the entire device.

[0016] The bottom of the adjusting bolt 24 is rotatably connected to the bearing mounted on the top of the auxiliary roller 5, allowing the operator to easily fine-tune the position of the auxiliary roller 5.

[0017] The inner wall of the sleeve 17 is provided with an internal thread groove 18. The bottom position of the external thread rotating rod 16 is threadedly connected to the internal thread groove 18, which realizes the rapid lifting and lowering adjustment of the mounting platform 7 and the flattening roller 9.

[0018] A buffer mechanism 19 is fixedly connected to all four sides between the top plate 10 and the mounting platform 7. The buffer mechanism 19 includes a damping rod and a buffer spring, which can effectively absorb and disperse the vibration and impact generated by the device during operation.

[0019] One side of the horizontal gear 15 meshes with the vertical gear 14, so that the power output by the variable frequency motor 12 can be efficiently transmitted to the external thread rotating rod 16, thereby driving the lifting and lowering of the mounting platform 7 and the flattening roller 9.

[0020] The center of the bottom of the heat shrink film body 4 is in contact with the top of the support platform 3.

[0021] Working principle: First, the heat shrink film body 4 passes between the support roller 6 and the auxiliary roller 5, and continues to be transported after being flattened by the flattening roller 9. The auxiliary roller 5 slides within the movable passageway 20 via the support slide plate 21. The operator can fine-tune the position of the auxiliary roller 5 using the adjusting bolt 24 to accommodate heat shrink films of different thicknesses. When the height of the flattening roller 9 needs to be adjusted, the frequency converter motor 12 starts and drives the longitudinal gear 14 to rotate via the main shaft 13. Since the transverse gear 15 meshes with the longitudinal gear 14, the transverse gear 15 also rotates, thereby driving the external thread rotating rod 16 to rotate. Since the bottom of the external thread rotating rod 16 is threadedly connected to the internal thread groove 18 on the inner wall of the sleeve 17, the rotation of the external thread rotating rod 16 is converted into the lifting and lowering motion of the sleeve 17 and the mounting platform 7, thus realizing the lifting and lowering adjustment of the flattening roller 9. During the operation of the device, the buffer mechanism 19 between the top plate 10 and the mounting platform 7 can effectively absorb and disperse vibration and impact, ensuring the stable operation of the device. At the same time, the stable support of the support rod 22 for the auxiliary roller 5 also enhances the stability of the entire device.

[0022] In summary, this anti-wrinkle pressing device for heat shrink film production, through the design of adjusting bolts 24, fixing plate 23, support slide plate 21, movable channel 20, and auxiliary roller 5, enables the device to adjust the distance between the auxiliary roller 5 and the support roller 6. This allows it to adapt to heat shrink films of different thicknesses and materials, ensuring optimal support and guidance during transport. This helps reduce wrinkles and uneven stretching, improving product quality. Furthermore, the design of the variable frequency motor 12, longitudinal gear 14, transverse gear 15, external threaded rotating rod 16, sleeve 17, and mounting platform 7 allows the device to adjust the distance between the flattening roller 9 and the heat shrink film. This ensures that the flattening roller 9 effectively flattens the heat shrink film, helping to eliminate wrinkles on the surface of the heat shrink film and improving the product's appearance quality.
