Description

Technical Field

[0001] This utility model relates to the field of double-sided release film production technology, and in particular to a double-sided release film production and processing device. Background Technology

[0002] Double-sided release film, also known as double-sided release film or double-sided anti-stick film, is a film material in which release agent is coated on both sides of the film substrate. During the production process of double-sided release film, it needs to be slit and cut, and then rolled into small rolls.

[0003] A search revealed that utility model CN222430988U discloses a double-sided release film production and processing device. However, this device lacks the following advantages in use: rotating each threaded rotating ring causes the corresponding blade mounting bracket to move left and right under the action of the threads, allowing the cutting blade to move normally and thus adjust the width of the double-sided release film after segmentation. This adjustment method is not only inefficient but also prone to reduced cutting accuracy due to insufficient operator experience. Furthermore, the dust removal roller lacks self-cleaning, requiring frequent shutdowns for cleaning, which affects production efficiency. Therefore, we propose a double-sided release film production and processing device. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies, such as the low efficiency and susceptibility to operator error in manually adjusting the cutting blade position to change the cutting width, and the lack of self-cleaning function of the dust removal roller, which requires frequent shutdowns for cleaning and affects production efficiency. Therefore, this invention proposes a double-sided release film production and processing device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A double-sided release film production and processing device includes a frame, with an unwinding roller and a take-up roller at the top of the frame, a limiting rod fixedly installed inside the frame, and multiple cutting boxes slidably connected to the limiting rod, each cutting box containing a cutting component.

[0007] The cutting assembly includes a first drive shaft that is rotatably mounted. One end of the first drive shaft extends to the outside of the cutting box and a cutting blade is fixedly mounted thereon. A first drive gear is provided on the first drive shaft. The first drive gear meshes with a spline gear that is rotatably mounted inside the cutting box. The spline gear and the spline shaft are slidably connected through a slide groove and a slider.

[0008] The frame is equipped with two symmetrical dust removal rollers that rotate inside.

[0009] Each cutting box is equipped with an adjustment assembly, which includes a third transmission gear that meshes with a rack on a limit rod. The third transmission gear is connected to a second motor via a worm gear transmission mechanism.

[0010] The frame is equipped with a self-cleaning component, which includes two scrapers that contact the surface of the corresponding dust removal rollers and a cleaning box that connects to the negative pressure pipe. The inner wall of the cleaning box is in contact with and sealed to the outer wall of the dust removal roller.

[0011] In one possible design, the worm gear transmission mechanism includes a third transmission shaft rotatably disposed inside the cutting box, a worm gear fixedly sleeved on the third transmission shaft, and a worm meshing with the worm gear. The worm is driven by a second motor, and the third transmission gear is fixedly sleeved on the third transmission shaft.

[0012] In one possible design, the bearings of the unwinding roller and the take-up roller are fixed in a groove at the top of the frame by snap-fit, and a second transmission gear is fixedly sleeved on both the take-up roller and the second transmission shaft, and the two second transmission gears mesh to drive each other.

[0013] In one possible design, the dust removal roller located at the top slides in the first groove of the connecting frame via two first sliders and is driven to rise and fall by two cylinders above the frame. One of the first sliders is fixedly connected to a third motor, and the output end of the third motor is connected to the corresponding dust removal roller.

[0014] In one possible design, one cleaning box is fixedly connected to the corresponding first slider at both ends, and the other cleaning box is fixedly connected to the inside of both sides of the frame. The two scrapers are inclinedly arranged in the corresponding two cleaning boxes, and the two scrapers form a scraping contact with the surface of the corresponding dust removal roller. Both cleaning boxes are connected to an external vacuum cleaner through a negative pressure pipe.

[0015] In one possible design, the frame is provided with a tension rod, which is slidably connected to a second slide groove via a second slider. The second slide groove is provided with a slide rod and a spring sleeved on the slide rod, with the two ends of the spring abutting against the top of the second slide groove and the second slider, respectively.

[0016] In one possible design, two limiting rollers are rotatably connected inside the frame, and the two limiting rollers are symmetrically arranged on both sides of multiple cutting boxes.

[0017] In one possible design, a rubber pad for increasing friction is provided in the groove at the top of the frame.

[0018] In this application, firstly, during the production of double-sided release film, the release film roll is placed on the unwinding roller, and the bearing on the unwinding roller is fixed in the groove at the top of the frame by a buckle. A rubber pad to increase friction is set in the groove to fix the two bearings and achieve stable installation of the unwinding roller. Then, the first motor is started, and its output end drives the second transmission shaft to rotate. Through the transmission of the transmission sprocket and chain, the spline shaft rotates, which in turn drives the spline gear and the first transmission gear to rotate, and finally drives the cutting blade to rotate for cutting, realizing the transmission of cutting power. Finally, the take-up roller, driven by the second transmission gear, rewinds the cut release film, completing the entire production process.

[0019] When the cutting specifications are adjusted as required, the second motor is started, and its output end drives the worm gear to rotate. Through the transmission with the worm wheel, the third transmission shaft and the third transmission gear, the cutting box moves on the limit rod, realizing flexible adjustment of the cutting position and size.

[0020] During the process of the release film running between the unwinding and rewinding rollers, symmetrically arranged dust removal rollers remove dust to ensure product cleanliness. The spacing between these symmetrically arranged dust removal rollers can be adjusted by a cylinder to accommodate double-sided films of various thicknesses. During the cleaning process, a scraper removes surface dust, while a vacuum cleaner connected to a negative pressure pipe sucks the dust away, achieving automatic self-cleaning of the dust removal rollers.

[0021] Meanwhile, the tension bar, under the action of the spring, can automatically adjust the tension of the release film to ensure operational stability, while the limit roller guides and limits the release film to ensure accurate running trajectory.

[0022] Beneficial effects: In this utility model, the double-sided release film production and processing device, by setting multiple cutting boxes and adjustment components that can move on the limiting rod, can automatically and flexibly adjust the cutting position and cutting size according to actual needs, so as to realize the production of double-sided release films of different specifications.

[0023] In this utility model, the double-sided release film production and processing device improves the accuracy of the cutting width by adjusting the transmission mode of the worm gear in the component. At the same time, the worm gear with self-locking characteristics prevents displacement during use, which could lead to deviations in the cutting width.

[0024] In this utility model, the double-sided release film production and processing device can remove dust from the double-sided release film through a dust removal roller and a self-cleaning component, ensuring product cleanliness. At the same time, through the self-cleaning method combining scraper and negative pressure dust collection, it can automatically remove dust and impurities from the surface of the dust removal roller, maintain the efficient operation of the dust removal roller, reduce maintenance costs, and ensure the stability and consistency of product quality.

[0025] In this invention, the movement of multiple cutting boxes is controlled in coordination with the adjustment component driven by the worm gear and the limit rod. Based on high-precision displacement adjustment, the self-locking characteristic of the worm gear is used to eliminate vibration offset, ensuring the stability of the cutting width of different specifications of film materials. The self-cleaning component integrating scraper and negative pressure dust collection removes impurities from the surface of the dust removal roller through dynamic contact scraping, and combines the negative pressure pipeline to extract dust in real time, extending the high-efficiency dust removal cycle and reducing the need for downtime maintenance.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0034] Example 1: Refer to Figure 1-6 A production processing device includes a frame 1, which serves as the main support structure. The top of the frame 1 houses an unwinding roller 2 and a take-up roller 3, which respectively handle the unwinding and take-up of the double-sided release film. A limiting rod 5 is fixedly installed inside the frame 1, and multiple cutting boxes 6 slide through the limiting rod 5, allowing them to move along it. Inside the frame 1, two dust removal rollers 4 are symmetrically rotated vertically between the unwinding roller 2 and the multiple cutting boxes 6, used for dust removal from the double-sided release film. Between the multiple cutting boxes 6 and the take-up roller 3, a tension rod 28 is installed to adjust the tension of the release film, and a limiting roller 31 is also provided to guide and limit the movement of the double-sided release film.

[0035] The cutting assembly is installed inside each cutting box 6. A first drive shaft 7 is rotatably mounted inside the cutting box 6, with one end extending to the outside of the cutting box 6 and fixedly fitted with a cutting blade 8 for cutting double-sided release film. The portion of the first drive shaft 7 located inside the cutting box 6 is fixedly fitted with a first drive gear 32, which meshes with a splined gear 9. A splined shaft 10 is rotatably connected inside the frame 1, sliding through the cutting box 6 and slidably connected to the splined gear 9 via a groove and slider structure.

[0036] The output end of the first motor 14, fixed on one side of the frame 1, is fixedly connected to the second drive shaft 12. Both the second drive shaft 12 and the spline shaft 10 are fixedly fitted with drive sprockets 11, which are connected by a chain 13. When the first motor 14 starts, it drives the second drive shaft 12 to rotate, which in turn drives the spline shaft 10 to rotate via the chain 13. The spline shaft 10 drives the spline gear 9 to rotate, which in turn drives the first drive shaft 7 to rotate via the first drive gear 32, thus realizing the rotational cutting action of the cutting blade 8.

[0037] The adjustment assembly is used to drive the cutting box 6 to move on the limit rod 5 to cut out double-sided release films of different specifications. Each cutting box 6 is equipped with an adjustment assembly, which mainly includes a third drive shaft 16, a third drive gear 20, a rack 21, a worm gear 17, a worm 18, and a second motor 19.

[0038] The third drive shaft 16 is rotatably mounted inside the cutting box 6. The third drive gear 20 is fixedly sleeved on the third drive shaft 16 and meshes with the rack 21 fixed to the outer wall of the limiting rod 5. A worm gear 17 is also fixedly sleeved on the third drive shaft 16 and meshes with the worm 18 rotatably connected inside the cutting box 6. When the position of the cutting box 6 needs to be adjusted, the second motor 19 is started, and its output end drives the worm 18 to rotate. The worm 18 drives the worm gear 17 to rotate, which in turn drives the third drive shaft 16 to rotate. The third drive gear 20 rolls on the rack 21, causing the cutting box 6 to move along the limiting rod 5 to the desired position.

[0039] Two bearings are fixedly mounted on both the unwinding roller 2 and the take-up roller 3. A groove corresponding to the bearing is formed on the top of the frame 1, and a rubber pad to increase friction is placed inside the groove. The groove also has a snap fastener; the bearing is placed in the groove and secured by the snap fastener, thus fixing the unwinding roller 2 and the take-up roller 3 to the top of the frame 1. Second transmission gears 15 are fixedly mounted on both the take-up roller 3 and the second transmission shaft 12, and the two second transmission gears 15 are meshed together. When the first motor 14 operates, it drives the take-up roller 3 to rotate via the second transmission shaft 12 and the second transmission gears 15, realizing the winding action of the double-sided release film.

[0040] Two first sliding grooves are symmetrically formed on the frame 1, and two first sliding blocks 22 slide within the first sliding grooves respectively. The dust removal roller 4 located above is rotatably connected to the two first sliding blocks 22 at both ends. The output ends of two cylinders 23 fixed at the top of the frame 1 slide into the first sliding grooves and are fixedly connected to the top of the corresponding first sliding blocks 22, allowing adjustment of the height of the upper dust removal roller 4. A third motor 24 is fixedly connected to one side of one of the first sliding blocks 22, and its output end is fixedly connected to the corresponding dust removal roller 4 to drive the dust removal roller 4 to rotate.

[0041] The self-cleaning assembly includes two cleaning boxes 25. One is fixed inside the frame 1 and located below the lower dust removal roller 4, while the other cleaning box 25 is fixedly connected at both ends to the corresponding first sliders 22. The outer walls of the two dust removal rollers 4 extend into the corresponding cleaning boxes 25. Scrapers 26 are fixedly installed inside the cleaning boxes 25, and the scrapers 26 contact the outer walls of the dust removal rollers 4. The cleaning boxes 25 are connected to a negative pressure pipe, which is connected to an external vacuum cleaner. When the dust removal rollers 4 rotate, the scrapers 26 scrape off the impurities adsorbed on the surface of the dust removal rollers 4. Under the action of the vacuum cleaner, the impurities are sucked into the cleaning boxes 25 through the negative pressure pipe and discharged, thus achieving self-cleaning of the dust removal rollers 4.

[0042] This application can be used in the field of double-sided release film production, as well as in other fields applicable to this application.

[0043] Example 2: Reference Figure 2-6 An improvement upon Embodiment 1: A double-sided release film production and processing device, applied to the field of double-sided release film production technology, comprises two symmetrically arranged second slide grooves on a frame 1 between multiple cutting boxes 6 and winding rollers 3. Second sliders 27 slide within the second slide grooves, and the two second sliders 27 are rotatably connected to a tension rod 28, which is located close to one side of each other. A vertically fixed slide rod 29 is installed inside the second slide groove and fitted with a spring 30. The slide rod 29 slides through the second sliders 27, and the two ends of the spring 30 respectively abut against the inner top wall of the second slide groove and the top of the second slider 27. During the transmission of the double-sided release film, the elasticity of the spring 30 allows the tension rod 28 to move up and down, adjusting the tension of the release film.

[0044] Two limiting rollers 31 are rotatably connected inside the frame 1, located on both sides of multiple cutting boxes 6, to limit and guide the double-sided release film, ensuring that the release film maintains a stable path during transmission.

[0045] However, as is well known to those skilled in the art, the working principles and wiring methods of the first motor 14, the second motor 19 and the third motor 24 are commonplace and are all conventional methods or common knowledge. They will not be described in detail here. Those skilled in the art can make any selections according to their needs or convenience.

The dimensions and shapes of the components shown are not actual limitations but are merely schematic representations. In actual implementation, the components can be reasonably configured and adjusted according to specific needs and actual conditions.

[0047] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
