Description

Technical Field

[0001] This utility model relates to the field of release film processing technology, and in particular to a pressing mechanism for release film processing. Background Technology

[0002] Release film is a thin film with release properties. It is usually made of plastic film as the base material and is treated with release agents such as silicone oil. It can form a low adhesion strength with the surface of a specific adhesive and can be easily peeled off from the adhesive material during use. When the release film is bonded to the product, a pressing machine is required. The pressing machine is used to press the release film and the product together. The pressing machine consists of an unwinding mechanism, a pressing roller, and a winding mechanism. During use, the release film and the product are first fed in through the unwinding mechanism, pressed by the pressing roller, and then wound up by the winding mechanism to complete the production.

[0003] To avoid damaging the release film and the product during the pressing process, the surface of the pressing roller is covered with a ring of rubber. However, the rubber will gradually harden due to oxidation after long-term use. If it is not inspected and replaced in time, the elasticity will decrease, which will cause the two pressing rollers to be unable to press the release film and the product completely. Therefore, this application provides a pressing mechanism for release film processing to meet the requirements. Summary of the Invention

[0004] This invention provides a pressing mechanism for release film processing to solve the problem that the two pressing rollers cannot fully press the release film onto the product because the rubber elasticity on the surface of the pressing rollers is not detected in time.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] A pressing mechanism for release film processing includes a pressing machine, the pressing machine consisting of a base and two pressing rollers mounted on top of the base, and further comprising:

[0007] The detection mechanism includes two pressure sensors for detecting the elasticity of the pressing rollers, two sets of vertical drive components are installed on the base, a crossbeam is fixed between the two sets of vertical drive components, the vertical drive components are used to drive the crossbeam to move vertically, a horizontal drive component is slidably connected to the surface of the crossbeam, the pressure sensor is installed at the end of the horizontal drive component, and a roller is rotatably connected to the end of the pressure sensor.

[0008] When testing the surface elasticity of the pressing roller, the roller is placed against the surface of the pressing roller. After the roller is placed against the surface, the horizontal drive assembly is pushed to make the roller roll along the surface of the pressing roller.

[0009] Preferably, the horizontal drive assembly includes a fixed base, a sliding sleeve that can slide along the crossbeam is fixed to the top of the fixed base, a drive component is fixed inside the fixed base, an mounting plate is installed at the end of the drive component, two inclined rods are fixed to the side of the mounting plate, and pressure sensors are embedded in the ends of the inclined rods.

[0010] Preferably, a support plate is fixed to the end of the pressure sensor, a rotating shaft is fixed to the support plate, a roller is rotatably connected to the surface of the rotating shaft, a limit plate is fixed to the end of the rotating shaft, and the surface of the limit plate is slidably connected to the surface of the roller.

[0011] Preferably, the end of the inclined rod is threaded with a protective cover, which is fitted onto the surface of the roller. Two columns are fixed on the top of the fixing seat. During testing, the protective cover is removed from the inclined rod and fitted onto the columns.

[0012] Preferably, the limiting plate is a magnetic plate, the surface of the roller has two insertion holes, and the end of the protective cover is fixed with two plugs. When cleaning the roller, the plugs are inserted into the insertion holes, and the protective cover is magnetically attracted to the limiting plate.

[0013] Preferably, the crossbeam is a polygonal beam, and the shape of the sliding sleeve is adapted to the shape of the crossbeam.

[0014] Preferably, a handle is installed on the top of the mounting base.

[0015] Preferably, the contact surface between the roller and the pressing roller is provided with a groove, and the groove is adapted to the shape of the pressing roller.

[0016] Compared with the prior art, this utility model has at least the following beneficial effects:

[0017] In the above scheme, by setting pressure sensors and rollers, after the pressing roller is installed, the vertical drive component drives the crossbeam to move down, and the crossbeam drives the horizontal drive component to move down. Then, the drive component extends towards the pressing roller, so that the roller is in contact with the surface of the pressing roller. After contact, the horizontal drive component is pushed to make the roller roll along the surface of the pressing roller to detect the initial elastic value of the rubber on the surface of the newly replaced pressing roller. After the detection is completed, the roller moves up to reset. After the pressing roller has been used for a period of time, the surface rubber is detected again by pressure sensors and rollers. By comparing the two values, timely detection of the pressing roller can be achieved, avoiding insufficient pressing due to the decrease of the elasticity of the pressing roller.

[0018] By setting a protective cover, when no testing is required, the cover is fitted onto the roller surface to prevent dust and other impurities from adhering to the roller surface, avoiding interference from foreign objects between the roller and the pressing roller, and ensuring testing accuracy.

[0019] By setting up inserts and sockets, after the roller moves along the surface of the pressing roller, the insert at the end of the protective cover is inserted into the socket, and the wiping cloth is attached to the roller. The protective cover drives the roller to rotate, which can prevent fingers from contacting the roller and prevent impurities on the fingers from adhering to the roller, thus further ensuring the accuracy of the test.

[0028] As shown in the figure, specific structures and devices are marked in the figure to clearly illustrate the structure of the embodiments of this utility model.

According to specific needs, those skilled in the art can adjust or modify these devices and environments, and such adjustments or modifications are still included in the scope of the appended claims. Detailed Implementation

[0029] The pressing mechanism for release film processing provided by this utility model will be described in detail below with reference to the accompanying drawings and specific embodiments. It should also be noted that, in order to make the embodiments more detailed, the following embodiments are the best and preferred embodiments, and those skilled in the art can also use other alternative methods to implement some known technologies; moreover, the accompanying drawings are only for more specific description of the embodiments and are not intended to specifically limit this utility model.

[0030] like Figures 1-7 As shown, an embodiment of this utility model provides a pressing mechanism for release film processing, including a pressing machine, which consists of a base 1 and two pressing rollers 2, the two pressing rollers 2 being mounted on the top of the base 1, and further including:

[0031] The detection mechanism 3 includes two pressure sensors 11 for detecting the elasticity of the pressing roller 2. Two sets of vertical drive components 4 are installed on the base 1. A crossbeam 5 is fixed between the two sets of vertical drive components 4. The vertical drive components 4 are used to drive the crossbeam 5 to move vertically. A horizontal drive component 6 is slidably connected to the surface of the crossbeam 5. The pressure sensor 11 is installed at the end of the horizontal drive component 6. A roller 13 is rotatably connected to the end of the pressure sensor 11. The vertical drive component 4 includes two sets of support seats. A servo motor is fixed at the top of the support seat. The two servo motors are controlled to rotate synchronously by a servo controller. A through groove is opened on the side of the support seat. A slider is slidably connected in the through groove. A screw is threaded through the top of the slider. The top of the screw is fixed to the end of the output shaft of the servo motor. During detection, the servo motor drives the screw to rotate. After the screw rotates, it drives the slider to slide downward on the inner wall of the through groove. The crossbeam 5 is fixed between the two sliders. When the slider moves downward, the slider will drive the crossbeam 5 to move downward.

[0032] When testing the surface elasticity of the pressing roller 2, the roller 13 is attached to the surface of the pressing roller 2. After attachment, the horizontal drive assembly 6 is pushed to make the roller 13 roll along the surface of the pressing roller 2. The base 1 provides stable support for the pressing roller 2 and the detection mechanism 3, ensuring the stability of the pressing and detection process. The two pressing rollers 2 work together to achieve the pressing process of the release film. Its surface elasticity directly affects the pressing quality. The vertical drive assembly 4 can drive the crossbeam 5 to move up and down, flexibly adjusting the height of the horizontal drive assembly 6 and the pressure sensor 11 to adapt to the detection requirements of different specifications of pressing rollers 2. The horizontal drive assembly 6 can drive the pressure sensor 11 and Roller 13 moves horizontally along crossbeam 5, allowing it to roll against the surface of pressing roller 2, thus enabling detection of the elasticity of the entire surface of pressing roller 2. Pressure sensor 11 can accurately collect pressure data when roller 13 contacts pressing roller 2, reflecting the change in elasticity of the rubber on the surface of pressing roller 2. The rotating connection of roller 13 can reduce frictional damage to the surface of pressing roller 2 during detection, while ensuring the continuity of contact and the accuracy of detection data. By comparing the values ​​of initial detection and periodic re-inspection, the attenuation of elasticity of pressing roller 2 can be detected in time, avoiding insufficient pressing of release film due to insufficient elasticity, and ensuring product quality stability.

[0033] like Figures 3-6 As shown, in this embodiment, the horizontal drive assembly 6 includes a fixed base 7. A sliding sleeve that can slide along the crossbeam 5 is fixed to the top of the fixed base 7. A drive component 8 is fixed inside the fixed base 7. An mounting plate 9 is installed at the end of the drive component 8. Two inclined rods 10 are fixed to the side of the mounting plate 9. The pressure sensor 11 is embedded in the end of the inclined rod 10. The fixed base 7 is slidably connected to the crossbeam 5 through the sliding sleeve, providing a stable moving base for the horizontal drive assembly 6 and ensuring the smoothness of horizontal movement. The drive component 8 can push the mounting plate 9 to extend and retract, flexibly adjusting the distance between the pressure sensor 11 and the roller 13 and the pressing roller 2, which is convenient for controlling the bonding force and adapting to different detection scenarios, such as initial contact and pressure adjustment. The two inclined rods 10 support the pressure sensor 11 from different angles, so that the roller 13 can fit more closely to the arc surface of the pressing roller 2, improving the tightness of the contact. The inclined design can also disperse the pressure, avoiding damage to the pressure sensor 11 due to excessive force at a single point, and extending its service life. The mounting plate 9 transmits the power of the drive component 8 to the inclined rods 10, ensuring the stability of the linkage of each component.

[0034] like Figure 5 and Figure 6As shown in this embodiment, a support plate 12 is fixed to the end of the pressure sensor 11, and a rotating shaft is fixed on the support plate 12. A roller 13 is rotatably connected to the surface of the rotating shaft, and a limit plate 15 is fixed to the end of the rotating shaft. The surface of the limit plate 15 is slidably connected to the surface of the roller 13. The support plate 12 provides connection support between the pressure sensor 11 and the rotating shaft, enhancing structural stability. The rotating shaft provides a rotation fulcrum for the roller 13, ensuring that the roller 13 can rotate flexibly, reducing frictional resistance during detection, making the rolling process smoother, and avoiding interference with pressure data acquisition due to jamming. The limit plate 15 can limit the axial displacement of the roller 13, preventing it from falling off the rotating shaft. At the same time, it slides in contact with the surface of the roller 13 without affecting the rotation of the roller 13, ensuring the safety and continuity of the detection process.

[0035] like Figure 3 , Figure 4 and Figure 7 As shown in this embodiment, a protective cover 16 is threaded onto the end of the inclined rod 10. The protective cover 16 is fitted onto the surface of the roller 13. Two columns are fixed to the top of the fixing base 7. During testing, the protective cover 16 is removed from the inclined rod 10 and fitted onto the columns. In the non-testing state, the protective cover 16 is threaded onto the inclined rod 10 and covers the roller 13, which can effectively prevent dust and impurities from adhering to the surface of the roller 13, and avoid impurities from being trapped between the roller 13 and the pressure roller 2 during testing, ensuring tight contact and accuracy of pressure data. During testing, the protective cover 16 can be removed and fitted onto the columns, which is convenient for storage and does not occupy extra space, avoiding loss or interference with the testing operation. The threaded connection makes it easy to install and remove the protective cover 16, and the columns provide temporary fixing points for it, ensuring the convenience of operation.

[0036] like Figure 6 As shown in this embodiment, the limiting plate 15 is a magnetic plate, and the surface of the roller 13 has two insertion holes 18. The end of the protective cover 16 is fixed with two plugs 17. When cleaning the roller 13, the plugs 17 are inserted into the insertion holes 18, and the protective cover 16 is magnetically attracted to the limiting plate 15. When cleaning the roller 13, the insertion of the plugs 17 into the insertion holes 18 can realize the linkage between the protective cover 16 and the roller 13. Rotating the protective cover 16 can drive the roller 13 to rotate synchronously, which is convenient for thoroughly cleaning the surface of the roller 13. The magnetism of the limiting plate 15 can attract the protective cover 16, preventing the protective cover 16 from falling off during the cleaning process and ensuring operational stability. This design avoids direct contact between fingers and the roller 13, preventing oil and impurities on the hands from contaminating the roller 13, further ensuring the accuracy of subsequent testing, and making the cleaning operation more convenient and efficient.

[0037] like Figure 2As shown in this embodiment, the crossbeam 5 is a polygonal beam, and the shape of the sliding sleeve is adapted to the shape of the crossbeam 5. The polygonal crossbeam 5 and the adapted sliding sleeve cooperate to effectively prevent the sliding sleeve from rotating on the crossbeam 5, ensuring the directional stability of the horizontal drive assembly 6 during movement, avoiding the pressure sensor 11 and roller 13 from deviating from the contact angle with the pressing roller 2 due to rotation, and ensuring the accuracy of the detection position. Compared with a circular beam, the polygonal structure provides better guidance, making horizontal movement smoother, reducing jamming, and improving detection efficiency.

[0038] like Figure 3 As shown in this embodiment, a handle is installed on the top of the fixed base 7. The handle provides a convenient force application point for the operator to push the horizontal drive component 6, making the operation of the roller 13 rolling along the surface of the pressing roller 2 more effortless and controllable. The speed and direction of horizontal movement can be precisely controlled through the handle, ensuring that the roller 13 contacts the surface of the pressing roller 2 evenly, avoiding pressure data fluctuations caused by uneven movement, and improving the stability and accuracy of the detection.

[0039] like Figure 5 and Figure 6 As shown in this embodiment, the contact surface between the roller 13 and the pressing roller 2 is provided with a groove 14. The groove 14 is adapted to the shape of the pressing roller 2. The shape of the groove 14 is adapted to the pressing roller 2, which can increase the contact area between the roller 13 and the pressing roller 2, making the contact tighter and more stable, and preventing the roller 13 from slipping off the surface of the pressing roller 2 during detection. At the same time, the larger contact area can make the pressure distribution more uniform, reduce the damage to the rubber surface of the pressing roller 2 caused by excessive local pressure, and also allow the pressure sensor 11 to collect more representative pressure data, thereby improving the detection accuracy.

[0040] Working principle: After the pressing roller 2 is installed or replaced, the protective cover 16 is removed from the surface of the roller 13 and sleeved on the column at the top of the fixed base 7. The vertical drive assembly 4 drives the crossbeam 5 to move down, and the crossbeam 5 drives the horizontal drive assembly 6 to move down. Then the drive component 8 extends towards the pressing roller 2, so that the roller 13 fits against the surface of the pressing roller 2, and the groove 14 of the roller 13 is adapted to the shape of the pressing roller 2.

[0041] After bonding, the horizontal drive assembly 6 is pushed to make the roller 13 roll along the surface of the pressing roller 2. The pressure sensor 11 detects the initial elastic value of the rubber on the surface of the new pressing roller 2. After the detection is completed, the vertical drive assembly 4 drives the roller 13 to move up and reset. After the pressing roller 2 has been used for a period of time, the above operation is repeated to detect again, and the two values ​​are compared to determine the change in elasticity.

[0042] When no testing is required, remove the protective cover 16 from the column, thread it onto the diagonal bar 10 and cover the roller 13 to prevent impurities from adhering;

[0043] When the roller 13 needs to be cleaned, remove the protective cover 16 and insert its end plug 17 into the socket 18 of the roller 13. The protective cover 16 is magnetically attached to the magnetic limiting plate 15. Place the rag on the roller 13 and the roller 13 will rotate through the protective cover 16 to complete the cleaning, avoiding contamination from finger contact.

[0044] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
