Description

Technical Field

[0001] This utility model belongs to the field of PVC film winding technology, specifically relating to a paper tube quick-assembly PVC film winding mechanism. Background Technology

[0002] In modern industrial production, PVC film, as an important polymer material, is widely used in packaging, building materials, agriculture, electronics and other fields. In order to meet the needs of high-efficiency production, paper tube quick-installation PVC film winding mechanism has emerged. This type of winding mechanism greatly improves the speed of paper tube replacement by optimizing the installation method of paper tube, reduces equipment downtime and improves production efficiency to a certain extent.

[0003] In the current PVC film production process, static electricity is easily generated on the film surface. This is because the film rubs against various equipment components during extrusion, stretching, and transport, accumulating a large amount of static charge. Simultaneously, factors such as humidity and temperature changes in the production environment, as well as surrounding electromagnetic interference, exacerbate the generation of static electricity on the film surface. When the PVC film is wound up, the static electricity on the surface attracts dust, impurities, and other tiny particles from the air, causing the film surface to become covered in dust. This dust can easily affect the appearance quality of the film, reducing its transparency and gloss, and can also create defects within the film, ultimately impacting the final product quality. Utility Model Content

[0004] The purpose of this invention is to provide a paper tube quick-assembly PVC film winding mechanism to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a paper tube quick-assembly PVC film winding mechanism, comprising:

[0006] A base plate, one end of which is connected to a conveyor frame. Two sets of adjustment components for adjusting the tension of the film during winding are connected to the top of the base plate. The adjustment components include a mounting base and a first cylinder. The mounting base is connected to the top of the base plate and the first cylinder is located inside the mounting base. An adjustment cylinder is provided on the top of the mounting base.

[0007] An electrostatic dust removal assembly is disposed between two sets of mounting bases and is used to adsorb dust particles on the surface of a film. The electrostatic dust removal assembly includes a dust removal shell connected to the top of a base plate. The dust removal shell is equipped with a pressure roller and a rotating roller, and both the pressure roller and the rotating roller are equipped with electrostatic bars.

[0008] Preferably, the piston rod of the first cylinder moves through the mounting base and is connected to the adjusting cylinder. An adjusting frame is slidably connected inside the adjusting cylinder, and a spring connects the adjusting frame and the adjusting cylinder.

[0009] Preferably, a tensioning roller is rotatably connected to one end of the adjusting frame located outside the adjusting cylinder.

[0010] Preferably, the dust collector housing has openings on both sides, a rotating frame is provided inside the dust collector housing, the pressure roller is rotatably connected to the bottom of the rotating frame through bearings, and the rotating roller is rotatably connected to the bottom of the dust collector housing through bearings.

[0012] Preferably, the dust collector housing is provided with guide rods at both ends of the rotating frame, and the two ends of the rotating frame are slidably sleeved on the surface of the guide rods.

[0013] Preferably, a winding frame is connected to one end of the top of the base plate, and two sets of mounting brackets for mounting winding drums are rotatably connected to the surface of the winding frame via bearings. The mounting brackets are provided with T-shaped mounting grooves.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] (1) The winding drum is installed by using T-shaped mounting blocks and T-shaped mounting slots and fixing it with bolts. This design makes the winding drum installation process simple and quick. Operators only need to align the T-shaped mounting blocks and insert them into the T-shaped mounting slots, and then tighten the bolts to complete the installation.

[0017] (2) An electrostatic dust removal assembly is set between the two sets of mounting seats. Electrostatic bars are provided in both the pressure roller and the rotating roller. The electrostatic field generated by the electrostatic bars can adsorb the dust particles adsorbed by the static electricity generated on the film surface due to friction, environmental factors, etc., effectively removing dust and impurities from the film surface. This not only improves the appearance quality of the film and increases its transparency and gloss, but also avoids the formation of defects in the film by dust, thus improving the quality of the final product.

[0024] 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.

[0025] This utility model provides, for example Figure 1-4 The paper tube quick-assembly PVC film winding mechanism shown includes:

[0026] The base plate 1 has a conveyor frame 2 connected to one end of its top. The top of the base plate 1 is connected to two sets of adjustment components for adjusting the tension of the film 3 during winding. The adjustment components include a mounting base 4 and a first cylinder 5. The mounting base 4 is connected to the top of the base plate 1 and the first cylinder 5 is located inside the mounting base 4. The top of the mounting base 4 is provided with an adjustment cylinder 6.

[0027] An electrostatic dust removal assembly is disposed between two sets of mounting bases 4 and is used to adsorb dust particles on the surface of the film 3. The electrostatic dust removal assembly includes a dust removal shell 7, which is connected to the top of the base plate 1. The dust removal shell 7 is provided with a pressure roller 8 and a rotating roller 9, and both the pressure roller 8 and the rotating roller 9 are provided with electrostatic bars 10.

[0028] The piston rod of the first cylinder 5 moves through the mounting base 4 and is connected to the adjusting cylinder 6. An adjusting frame 11 is slidably connected inside the adjusting cylinder 6, and a spring 12 is connected between the adjusting frame 11 and the adjusting cylinder 6.

[0029] The tensioning roller 13 is rotatably connected to one end of the adjusting frame 11 outside the adjusting cylinder 6. The tensioning roller 13 can be used to adjust the tension of the film 3 during winding.

[0030] The dust collector housing 7 has openings 16 on both sides, and a rotating frame 14 is provided inside the dust collector housing 7. The pressure roller 8 is rotatably connected to the bottom of the rotating frame 14 through a bearing, and the rotating roller 9 is rotatably connected to the bottom of the dust collector housing 7 through a bearing.

[0031] The top of the dust collector housing 7 is provided with a second cylinder 15, and the piston rod of the second cylinder 15 moves through the dust collector housing 7 and is connected to the rotating frame 14.

[0032] The dust collector housing 7 is provided with guide rods 24 at both ends of the rotating frame 14. The two ends of the rotating frame 14 are slidably sleeved on the surface of the guide rods 24. When the rotating frame 14 moves, the two ends slide on the surface of the guide rods 24. The moving direction of the rotating frame 14 can be guided by the guide rods 24, thereby enhancing the stability of the moving rotating frame 14.

[0033] One end of the base plate 1 is connected to a winding frame 17. Two sets of mounting brackets 19 for mounting winding drums 18 are rotatably connected to the surface of the winding frame 17 via bearings. The mounting bracket 19 is provided with a T-shaped mounting groove 20. Both ends of the winding drum 18 are connected to T-shaped mounting blocks 21. Bolts 23 are threaded into the mounting bracket 19. After the T-shaped mounting block 21 is inserted into the T-shaped mounting groove 20, the bolts 23 are screwed and fixed to the threaded holes 22 in the T-shaped mounting block 21. By rotating the bolts 23, they are screwed and fixed to the threaded holes 22 in the T-shaped mounting block 21, thereby firmly mounting the winding drum 18 on the mounting bracket 19 and realizing the quick loading and unloading of the winding drum 18.

[0034] This paper tube quick-install PVC film winding mechanism works by fitting a paper tube for winding film 3 onto the surface of a winding drum 18, then mounting the winding drum 18 onto a winding frame 17. The T-shaped mounting blocks 21 at both ends of the winding drum 18 are aligned from the top of the mounting frame 19 with the T-shaped mounting grooves 20 and slid into the T-shaped mounting grooves 20. The bolts 23 are then rotated to screw them into the threaded holes 22 within the T-shaped mounting blocks 21, thus securing the winding drum 18 firmly onto the mounting frame 19. Disassembly is simple: just unscrew the bolts 23 to easily remove the winding drum 18, enabling quick loading and unloading of the winding drum 18.

[0035] When the film 3 is wound up, the external motor is started to drive the mounting frame 19 to rotate, and the mounting frame 19 drives the winding drum 18 to rotate. When the film 3 is wound up, the two sets of electrostatic bars 10 can be energized. When the film 3 passes through the electrostatic dust removal assembly, when the film 3 comes into contact with the pressure roller 8 and the rotating roller 9, the pressure roller 8 and the rotating roller 9 are driven to rotate continuously in the dust removal box by friction. At this time, the electrostatic bars 10 in the pressure roller 8 and the rotating roller 9 are energized to generate an electrostatic field. The surface of the film 3 is statically charged due to friction and other reasons. The opposite charge generated by the electrostatic bars 10 will neutralize the static electricity on the surface of the film 3, so that the dust particles adsorbed on the surface of the film 3 lose their electrostatic adsorption force. At the same time, the electric field generated by the electrostatic bars 10 will directly attract the dust particles, adsorbing the dust particles onto the surface of the pressure roller 8 and the rotating roller 9, thereby achieving the purpose of removing dust from the surface of the film 3 and ensuring the cleanliness of the film 3 before winding up.

[0036] Furthermore, depending on the thickness of the film 3, when it is necessary to adjust the gap between the pressure roller 8 and the rotating roller 9, the second cylinder 15 can be activated. The piston rod of the second cylinder 15 extends or retracts, driving the rotating frame 14 to rise or fall on the guide rod 24. The raising and lowering of the rotating frame 14 will change the distance between the pressure roller 8 and the rotating roller 9, thereby adjusting the contact state between the pressure roller 8 and the rotating roller 9 and the film 3. After the dust particles are adsorbed onto the surface of the pressure roller 8 and the rotating roller 9, after the winding is completed and the machine is stopped, the operator can use a handheld vacuum cleaner to vacuum the surface of the pressure roller 8 and the rotating roller 9 after the machine is stopped. The vacuum cleaner head is brought close to the surface of the roller, and the suction force is used to remove the dust particles, cleaning the pressure roller 8 and the rotating roller 9 to ensure the subsequent electrostatic dust removal effect.

[0037] During the winding process, as the film 3 passes the tension roller 13, the first cylinder 5 inside the adjusting cylinder 6 extends and retracts according to the real-time tension of the film 3. When the tension of the film 3 changes, for example, if the tension is too low, the piston rod of the first cylinder 5 extends, causing the adjusting cylinder 6 to move upward. At this time, the adjusting frame 11 slides downward inside the adjusting cylinder 6, the spring 12 is compressed, and the tension roller 13 connected to the end of the adjusting frame 11 lifts upward to press against the film 3, thereby increasing the tension on the film 3. Conversely, when the tension is too high, the opposite operation can be performed to reduce the tension of the film 3, thereby achieving tension adjustment during the winding of the film 3.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
