Technical Field
[0001] The utility model belongs to the technical field of coiled material production, and in particular relates to a heat shrink film packaging machine for waterproof coiled material production. Background Art
[0002] During the production of waterproofing membranes, POF and PE films are commonly used to wrap the product's exterior to provide stability, coverage, and protection. The POF or PE film-wrapped membrane is conveyed via a conveyor into an oven for heating, causing the film to shrink and tightly wrap around the membrane, creating a sealed product.
[0003] However, there are significant differences in the physical properties of PE film and POF film. POF film is thin, yet tough, with a high shrinkage rate, allowing it to shrink quickly and adhere tightly to the surface of the roll. To ensure uniform shrinkage and adhesion in all directions, ensuring optimal packaging, rolls wrapped with POF film must rotate during transport. PE film, on the other hand, has poor tear resistance, and rotation during transport can lead to excessive stretching or damage, compromising packaging performance. Therefore, when wrapping rolls with POF or PE film, the corresponding packaging machine must be used. This makes the two films incompatible on the same equipment, increasing production costs and requiring the maintenance of separate packaging machines. Summary of the Invention
[0004] In order to overcome the problem in the background technology that when POF film or PE film is used to package coils, the corresponding packaging machine must be used, resulting in the two films being unable to be used interchangeably on the same equipment, which not only increases production costs but also requires different packaging machines to be maintained separately, resulting in a significant increase in maintenance costs. The utility model provides a heat shrink film packaging machine for the production of waterproof coils; the screw adjustment method can be used to quickly switch whether the roller rotates or not, and the POF film and PE film can be used interchangeably on the same equipment. The operation is convenient and flexible, which not only effectively reduces the packaging problems caused by the differences in the characteristics of the films, but also reduces the increase in production costs and maintenance costs caused by the use of corresponding equipment alone, thereby greatly improving the practicality and economic benefits of the device.

The chain is wound on the sprockets on the driving shaft and the driven shaft. Multiple groups of connecting rods are installed at equal intervals on the chain. The ends of the rollers are provided with positioning holes for docking with the connecting rods, and the ends of the rollers are sleeved on the connecting rods.
[0006] A guide rail is installed on the inner wall of the support plate, and a bearing in rolling contact with the guide rail is installed at the end of the roller. The outer diameter of the bearing is larger than the outer diameter of the roller and the gear.
[0007] The top end of the screw rod is provided with a crank handle which is convenient for rotation.
[0008] Beneficial effects of the utility model:

[0015] In order to make the purpose, technical solutions and beneficial effects of the present invention clearer, the preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings to facilitate understanding by technicians.
[0016] The utility model discloses a heat shrink film packaging machine for waterproof coiled material production, which mainly includes a machine base 1, a roller 2, a chain transmission mechanism 3, a motor 4, a gear 5, a rack 6, a support rod 7, a support block 8, a screw 9, a support plate 10, a driving shaft 11, a driven shaft 12, and an oven 17. The support plates 10 are installed on both sides of the top of the machine base 1, and the oven 17 is installed on the support plates 10. The driving shaft 11 and the driven shaft 12 are installed between the support plates 10. Shaft 12, two sets of chain transmission mechanisms 3 are installed between the driving shaft 11 and the driven shaft 12, and multiple rotatable rollers 2 are equidistantly installed between the chain transmission mechanisms 3. Gears 5 are installed at the ends of the rollers 2. The motor 4 is installed on the side wall of the machine base 1 and is connected to the driving shaft 11 for transmission; two sets of support blocks 8 are installed on the top of the support plate 10, and a screw 9 is threadedly connected to the support block 8. The bottom end of the screw 9 is rotatably installed on the support rod 7, and the rack 6 is installed at the bottom of the support rod 7, which is located directly above the chain transmission mechanism 3.
[0017] When packaging with POF film, the operator adjusts the screw 9 on the support block 8 to lower the support rod 7, thereby meshing the rack 6 with the gear 5 at the end of the roller 2. Driven by the chain drive 3, the roller 2 rotates as it moves forward due to the meshing with the rack 6, ensuring uniform shrinkage and adhesion of the POF film. When using PE film, the screw 9 is adjusted in the opposite direction, causing the support rod 7 to move upward and disengaging the rack 6 from the gear 5. This prevents the roller 2 from rotating during forward movement, thus preventing excessive stretching or damage to the PE film due to rotation. The present utility model, through the adjustment of the screw 9, quickly switches the roller 2 between rotating and non-rotating, enabling interchangeable use of POF and PE films on the same device. This convenient and flexible operation not only effectively reduces packaging issues caused by differences in film properties, but also reduces the increased production and maintenance costs associated with using separate devices for each, significantly improving the practicality and economic benefits of the device.
[0018] The chain transmission mechanism 3 includes a sprocket 301 and a chain 302. The sprocket 301 is installed at the end of the driving shaft 11 and the driven shaft 12. The chain 302 is wound on the sprocket 301 on the driving shaft 11 and the driven shaft 12. Multiple groups of connecting rods 13 are equidistantly installed on the chain 302. A positioning hole for docking with the connecting rod 13 is opened at the end of the roller 2, and the end of the roller 2 is sleeved on the connecting rod 13; it is convenient for installing and disassembling the roller 2, which provides convenience for maintenance and replacement of components.
[0019] A guide rail 14 is installed on the inner wall of the support plate 10, and a guide groove is opened at the top of the guide rail 14. A bearing 15 is installed at the end of the roller 2, which is in rolling contact with the guide rail 14. The outer diameter of the bearing 15 is larger than the outer diameter of the roller 2 and the gear 5, so that when the roller 2 moves forward, only the bearing 15 contacts the guide rail and rolls, while the gear 5 is in a suspended state; the guide rail 14 supports the roller 2 carrying the coil on the chain 302, providing guidance and stable support for the movement of the roller 2, ensuring that the roller 2 can run smoothly along the guide groove when moving forward, reducing shaking and deviation, and improving the stability of coil transportation.
[0020] The top of the screw rod 9 is provided with a crank 16 for easy rotation; the setting of the crank 16 allows the staff to rotate the screw rod 9 more conveniently and labor-savingly, thereby easily adjusting the position of the support rod 7 and improving work efficiency.
[0021] Working process:
[0022] When packaging with POF film, the operator adjusts the screw 9 on the support block 8 to lower the support rod 7, thereby meshing the rack 6 with the gear 5 at the end of the roller 2. Driven by the chain drive 3, the roller 2 rotates as it moves forward due to the meshing with the rack 6, ensuring uniform shrinkage and adhesion of the POF film. When using PE film, the screw 9 is adjusted in the opposite direction, causing the support rod 7 to move upward and disengaging the rack 6 from the gear 5. This prevents the roller 2 from rotating during forward movement, thus preventing excessive stretching or damage to the PE film due to rotation. The present utility model, through the adjustment of the screw 9, quickly switches the roller 2 between rotating and non-rotating, enabling interchangeable use of POF and PE films on the same device. This convenient and flexible operation not only effectively reduces packaging issues caused by differences in film properties, but also reduces the increased production and maintenance costs associated with using separate devices for each, significantly improving the practicality and economic benefits of the device.
[0023] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention and are not limiting. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the present invention.
