Description

Technical Field

[0001] This utility model relates to the field of release film production equipment technology, and in particular to an adjustable thickness release film forming device. Background Technology

[0002] Release film is a functional film used in electronics, packaging, printing and other fields. Adjustable thickness release film forming equipment is the key equipment for producing release films of different specifications. This equipment can precisely adjust the thickness of the release film by controlling the coating, extrusion and drying processes in the production process, so as to meet the diverse needs of different products for the performance of the release film. It is of great significance in improving production efficiency and reducing costs.

[0003] Early adjustable thickness release film forming devices mainly consisted of an unwinding mechanism, a coating roller, a pressure roller, and a rewinding mechanism. Thickness adjustment relied primarily on manual adjustment of the pressure roller spacing. This method was not only inefficient but also difficult to guarantee the accuracy of thickness adjustment, resulting in extremely poor uniformity of release film thickness. With technological advancements, existing devices employ an automatic adjustment system combining a screw and nut transmission mechanism, sensors, and a controller. Through real-time monitoring and feedback, automatic thickness adjustment is achieved, improving the accuracy and efficiency of thickness adjustment to some extent. However, existing forming devices still suffer from insufficient uniformity of release film thickness. Because existing devices use a screw and nut transmission to drive the pressure roller for thickness adjustment, the mechanical clearance of the screw and nut transmission and the uneven force at both ends of the pressure roller during operation cause slight angular deviations during roller movement. Furthermore, the uneven distribution of contact pressure between the pressure roller surface and the release film during operation leads to differences in the degree of compression of the release film at different lateral positions. Consequently, after thickness adjustment, the uniformity of the release film is difficult to achieve higher standards, failing to meet the requirements of some high-end applications with stringent requirements for release film thickness uniformity.

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.

[0032] Reference Figure 1 , Figure 3 and Figure 4This utility model provides an embodiment of an adjustable thickness release film forming device, including an H-shaped support 1. A discharge box 3 is fixedly connected to the top left side of the H-shaped support 1. The discharge box 3 is used to store release film raw materials. The raw materials are discharged from the bottom of the discharge box 3 and fall between the left auxiliary roller 8 and the pressing roller 5. Limiting slide rails 4 are fixedly connected to the front and rear sides of the inner wall of the H-shaped support 1. The pressing roller 5 is rotatably connected to the middle of the adjacent side of the two limiting slide rails 4. An electric telescopic rod 6 is fixedly connected to the left side of the inner wall of the H-shaped support 1. The left and right sides of the inner walls of the two limiting slide rails 4 are slidably connected to... There is a U-shaped plate 7. One end of the electric telescopic rod 6 is fixedly connected to the outer wall of the left U-shaped plate 7. An auxiliary roller 8 is rotatably connected to the inner wall of the U-shaped plate 7. A gear 10 is fixedly connected to the front side of the pressing roller 5. A rack 9 is fixedly connected to the outer wall of the U-shaped plate 7. The upper and lower sides of the outer wall of the gear 10 are respectively engaged with the outer walls of the corresponding rack 9. When the electric telescopic rod 6 is activated to extend or retract, it will push the left U-shaped plate 7 to slide within the limiting slide rail 4. Since the rack 9 on the U-shaped plate 7 is engaged with the gear 10 on the pressing roller 5, the movement of the U-shaped plate 7 will drive the gear 10 to rotate, causing the other... The U-shaped plate 7 on one side moves with the auxiliary roller 8, thereby causing the auxiliary rollers 8 on both sides to move relative to or away from the U-shaped plate 7. Collection blocks 11 are fixedly connected to the bottom front and rear sides of the inner wall of the H-shaped support 1. Excess material is scraped off to the collection blocks 11 for easy recycling. An inclined scraper 12 is fixedly connected to the bottom of the right-side U-shaped plate 7, which facilitates scraping off the film adhering to the pressing roller 5. A transmission assembly is provided on the inner wall of the H-shaped support 1, and a drying mechanism 2 is provided on the top right side of the H-shaped support 1 for drying the film. The component includes multiple rotating columns 14, the front and rear sides of which are rotatably connected to the bottom of the inner wall of the H-shaped bracket 1. A conveyor belt 15 is provided on the outer wall of the multiple rotating columns 14. A reduction motor 13 is fixedly connected to the front left side of the H-shaped bracket 1. The output end of the reduction motor 13 passes through the H-shaped bracket 1 and is fixedly connected to the left rotating column 14. When the reduction motor 13 is started, its output end drives the left rotating column 14 to rotate. Through the transmission of the conveyor belt 15, the multiple rotating columns 14 rotate synchronously, thereby driving the conveyor belt 15 to circulate and provide power for the transmission of the release film.

[0033] Specifically, when the geared motor 13 starts, its output drives the left rotating column 14 to rotate. Through the transmission of the conveyor belt 15, multiple rotating columns 14 rotate synchronously, thereby driving the conveyor belt 15 to circulate and providing power for the transfer of the release film. The discharge box 3 is used to store the release film raw material. The raw material is discharged from the bottom of the discharge box 3 and falls between the left auxiliary roller 8 and the pressing roller 5. When the electric telescopic rod 6 is activated to extend or retract, it will push the left U-shaped plate 7 to slide within the limit slide rail 4. Since the rack 9 on the U-shaped plate 7 meshes with the gear 10 on the pressing roller 5, the movement of the U-shaped plate 7 will drive the gear 10 to rotate, causing the other roller to rotate. The U-shaped plate 7 on one side moves with the auxiliary roller 8, causing the auxiliary rollers 8 on both sides to move relative to or away from the U-shaped plate 7. At the same time, the auxiliary roller 8 rotates on the inner wall of the U-shaped plate 7, and the auxiliary pressing roller 5 squeezes the release film. By controlling the extension and retraction of the electric telescopic rod 6, the distance between the pressing roller 5 and the auxiliary roller 8 can be adjusted to adjust the thickness of the release film. During the pressing process, the inclined scraper 12 facilitates the scraping off of the film attached to the pressing roller 5, and the excess material is scraped off to the collection block 11 for easy recycling. Thus, under the squeezing action of the auxiliary rollers 8 on both sides, the film is evenly attached.

[0034] Reference Figure 1 , Figure 3 and Figure 5 The drying mechanism 2 includes a U-shaped cover plate 201. The bottom of the U-shaped cover plate 201 is fixedly connected to the top right side of the H-shaped bracket 1. Multiple electric telescopic rods 202 are fixedly connected to the bottom of the U-shaped cover plate 201. A connecting plate 203 is fixedly connected to one end of each of the multiple electric telescopic rods 202. Rolling columns 204 are rotatably connected to the left and right sides of the bottom of the connecting plate 203. A hollow plate 205 is fixedly connected to the middle of the bottom side of the connecting plate 203. The electric telescopic rods 202 extend or shorten according to a preset program, driving the connecting plate 203 and the rolling columns 204 and the hollow plate 205 to descend to a suitable height. Multiple ultraviolet lamps 206 are fixedly connected to the inner wall of the hollow plate 205. The ultraviolet lamps 206 inside the hollow plate 205 are turned on, emitting ultraviolet light to dry the release film, so that the release film is quickly dried and formed.

[0035] Specifically, when the release film is transported to the bottom of the drying mechanism 2, the electric telescopic rod 202 extends or shortens according to the preset program, driving the connecting plate 203 and its rolling column 204 and hollow plate 205 to descend to a suitable height. The rolling column 204 can roll on the surface of the release film to avoid excessive compression of the release film. The ultraviolet lamp 206 inside the hollow plate 205 is turned on to emit ultraviolet light to dry the release film, so that the release film is quickly dried and formed.

[0036] Reference Figure 1 , Figure 2 and Figure 6An observation window 16 is provided on the front side of the discharge box 3. The observation window 16 allows the operator to clearly observe the storage, conveying and remaining amount of materials in the box without opening the discharge box 3. An outer frame 17 is fixedly connected to the outer wall of the observation window 16, which provides a stable support and protection structure for the observation window 16. A box cover 18 is threadedly connected to the top of the discharge box 3. The box cover 18 can effectively prevent dust, impurities and foreign objects from entering the discharge box 3. An inclined baffle 19 is fixedly connected to the bottom of the H-shaped bracket 1. The inclined baffle 19 can make the material flow more smoothly from the discharge box 3 into the space between the left auxiliary roller 8 and the crushing roller 5.

[0037] Specifically, the observation window 16 allows operators to clearly observe the storage, conveying, and remaining quantity of materials inside the discharge box 3 without opening it. The outer frame 17 provides a stable support and protective structure for the observation window 16, enhancing the connection strength between the observation window 16 and the discharge box 3 and preventing the observation window 16 from being damaged by external impacts or vibrations. The box cover 18 effectively prevents external dust, impurities, and foreign objects from entering the discharge box 3, avoiding contamination of the materials. The inclined baffle 19 allows materials to flow more smoothly from the discharge box 3 between the left auxiliary roller 8 and the crushing roller 5.

[0038] Reference Figure 1 , Figure 2 and Figure 6 Adjusting bolts 20 are threaded onto the front and rear sides of the right side of the discharge box 3. The adjusting bolts 20 can change the extension length of the adjusting bolts 20 on the discharge box 3. The bottom ends of the two adjusting bolts 20 are rotatably connected to the baffles 21, which can control the discharge volume and discharge speed of the material in the discharge box 3. A column 23 is fixedly connected to the top left side of the U-shaped cover plate 201. The column 23 provides a stable installation support structure for the warning light 24. The top of the column 23 is fixedly connected to the warning light 24, which can quickly determine the current operation of the equipment. In the process of release film forming, a temperature sensor 25 is fixedly connected to the top center of the U-shaped cover plate 201. The temperature sensor 25 can monitor the temperature changes of relevant areas in real time. A controller 22 is fixedly connected to the front center of the H-shaped bracket 1. The controller 22 is electrically connected to the electric telescopic rod 6, the electric telescopic rod 202 and the ultraviolet lamp 206 respectively. The controller 22 can control the starting and running power of the electric telescopic rod 6, the electric telescopic rod 202 and the ultraviolet lamp 206 respectively.

[0039] Specifically, the extension length of the adjusting bolt 20 on the discharge box 3 can be changed by adjusting bolt 20; the discharge amount and speed of the material in the discharge box 3 can be controlled by the baffle 21; the column 23 can provide a stable installation support structure for the warning light 24; the warning light 24 can quickly determine the current operating status of the equipment, take effective countermeasures in a timely manner, avoid the occurrence or expansion of accidents, and ensure the safety of equipment and personnel; the temperature sensor 25 can monitor the temperature changes of relevant areas in real time during the release film forming process; and the controller 22 can control the start-up and operation power of the electric telescopic rod 6, the electric telescopic rod 202, and the ultraviolet lamp 206 respectively.

[0040] Working principle: First, after the geared motor 13 starts, its output drives the left rotating column 14 to rotate. Through the transmission action of the conveyor belt 15, the multiple rotating columns 14 are synchronized, thereby causing the conveyor belt 15 to circulate and provide power for the transmission of the release film. The discharge box 3 serves as a storage facility for the release film raw materials. The raw materials are discharged from the bottom of the discharge box 3 and fall between the left auxiliary roller 8 and the pressing roller 5. When the electric telescopic rod 6 is activated, its extension or retraction action will push the left U-shaped plate 7 to slide within the limit slide rail 4. Since the rack 9 on the U-shaped plate 7 meshes with the gear 10 on the pressing roller 5, the U-shaped plate 7... The movement of the rollers will cause the gear 10 to rotate, which in turn causes the U-shaped plate 7 on the other side and the auxiliary roller 8 to move relative to or away from each other. At the same time, the auxiliary roller 8 rotates on the inner wall of the U-shaped plate 7, and the auxiliary pressing roller 5 squeezes the release film. By controlling the extension and retraction of the electric telescopic rod 6, the distance between the pressing roller 5 and the auxiliary roller 8 can be adjusted to achieve precise adjustment of the release film thickness. During the pressing process, the inclined scraper 12 helps to scrape off the film attached to the pressing roller 5, and scrapes off the excess material to the collection block 11 for easy recycling. Under the squeezing action of the auxiliary rollers 8 on both sides, the uniform adhesion of the film is ensured.

[0041] Furthermore, through the drying mechanism 2, when the release film is transported to the bottom of the drying mechanism 2, the electric telescopic rod 202 extends and retracts according to the preset program, driving the connecting plate 203 and its rolling column 204 and hollow plate 205 to descend to a suitable height. The rolling column 204 can roll on the surface of the release film to prevent excessive compression of the release film. At the same time, the ultraviolet lamp 206 in the hollow plate 205 is activated to release ultraviolet rays to perform drying treatment on the release film, thereby promoting the rapid drying and shaping of the release film.
