Description

Technical Field

[0001] This invention relates to the field of release paper performance testing technology, specifically a performance testing device for release paper. Background Technology

[0002] Release paper (also known as silicone paper or anti-stick paper) primarily serves to isolate sticky substances. It generally needs to be peeled off and discarded during use. Release paper is most widely used as a carrier for adhesive tapes or other adhesive products, and it also has applications in the food and medical industries.

[0003] Release paper can be classified according to whether it contains plastic, into plastic-coated release paper and plastic-free release paper; it can also be classified according to the release agent, into silicone release paper and non-silicone release paper. Plastic-coated release paper (divided into single-plastic and double-plastic release paper) has a certain degree of penetration of the release agent. Without a certain barrier, the release agent will penetrate into the paper, causing poor curing and excessive use of release agent (leading to high costs), among other problems. Plastic-free release paper mainly includes glassine, CCK, and other specially treated release papers.

[0004] The test methods for release paper performance testing include tape peel test, roller test, etc. (to evaluate the anti-sticking performance of release paper by simulating the actual use environment), temperature resistance test (because release paper needs to maintain its performance under different temperature conditions, the test usually includes high temperature and low temperature test to ensure that the release paper does not lose its function under extreme temperatures) and chemical resistance test (release paper will come into contact with various chemicals, so its chemical resistance needs to be tested, and the test includes resistance to chemicals such as acids, alkalis and solvents).

[0005] In temperature resistance testing of release paper, the temperature environment in which it is used is simulated to test its anti-sticking properties. However, in actual adhesion resistance testing, both the adhesive material and the release paper undergo varying degrees of deformation under different temperature conditions. Since the release paper is directly attached to the surface of the adhesive material, this deformation can easily affect the contact area between them, ultimately increasing or decreasing the resistance to peeling the release paper off the adhesive surface and reducing the accuracy of the measurement. Therefore, providing a performance testing device for release paper is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0006] To overcome the shortcomings of existing release paper performance testing methods, where both the adhesive material and the release paper undergo varying degrees of deformation under different temperature environments, and since the release paper is directly attached to the surface of the adhesive material, the contact area between the two is easily affected, ultimately increasing or decreasing the resistance to peeling the release paper off the adhesive material surface and reducing measurement accuracy, this application provides a performance testing device for release paper. This device passes one end of the release paper between the arc surface of the paper sheet wheel frame and the inner wall of the arc plate. A second electric push rod controls the side of the pressure plate facing the suspension frame to move closer to the arc plate, clamping and fixing the release paper. The device is then rotated... The cylinder controls the rotation of the drive gear, which drives the driven gear to rotate the sector plate, thereby causing the entire paper guide frame to rotate outside the paper wheel frame. One end of the release paper is pulled around the bottom of the paper wheel frame, and then the first electric push rod uses the suspension frame to control the paper wheel frame to move downwards, so that the release paper is squeezed between the paper wheel frame and the liquid adhesive. After the paper wheel frame retracts a certain distance to the top, the release paper can be pulled away from the paper baffle by controlling the tension gauge, so that the release paper is supported by the paper wheel frame and gradually peels off from the surface of the liquid adhesive. This allows the peeling resistance to be observed from the value displayed on the tension gauge, and finally the performance of the release paper at the target temperature can be analyzed and judged.

[0007] The technical solution adopted by the embodiments of this application to solve its technical problem is: A performance testing device for release paper includes an environmental simulation component and a paper fixing component, wherein the paper fixing component is disposed inside the environmental simulation component; The environmental simulation component includes a support base, and two simulator frames that interlock with each other are provided on the outside of the support base. A vertically arranged gantry frame is assembled and connected to the surface of the support base. A first electric push rod is assembled and connected to the center of the top of the gantry frame. The movable end of the first electric push rod passes through the interior of the gantry frame and is assembled and connected to a suspension frame. Liquid adhesive is provided inside the support base. The paper fixing assembly includes a paper wheel frame, a paper guide frame is rotatably connected to the outside of the paper wheel frame, the paper guide frame includes an arc plate, both ends of the arc plate are integrally formed with fan-shaped plates, a clamping member is hinged to the side of the arc plate away from the suspension frame, a seat bar is assembled to the inner wall of the top side of the gantry frame, and a tension gauge is provided on the side of the seat bar away from the gantry frame; The suspension frame is assembled and connected to the top of the paper wheel frame. The end of the fan-shaped plate away from the arc plate is coaxially assembled with the paper wheel frame. One end of the release paper is clamped between the inner wall of the arc plate and the clamping member. The paper guide frame rotates outside the paper wheel frame and passes around the bottom of the paper wheel frame. The paper wheel frame is movably connected between the two simulator frames and is movably connected to the inside of the bearing support.

[0008] In one possible implementation, the clamping member includes a pressure plate, the top of which on the side away from the suspension frame is integrally formed with a corner piece, one end of which is integrally formed with a stop strip, and a movable corner groove is formed on the arc surface of the paper wheel frame; the corner piece is hinged to the top of the arc plate on the side away from the suspension frame via a shaft, the shaft is sleeved with a torsion spring, the torsion spring is supported between the stop strip and the outer surface of the arc plate, and the pressure plate is movably connected inside the movable corner groove.

[0009] In one possible implementation, a push rod seat is welded to the outer wall of the arc plate on the side away from the clamping member, and a second electric push rod is hinged between the push rod seat and the corner piece.

[0010] In one possible implementation, a magnet is embedded in the side of the hanging frame facing the paper guide frame, and the magnet is attracted to the threaded upright. The top corner of the side of the paper guide frame facing the hanging frame is adapted to one side of the hanging frame.

[0011] In one possible implementation, a rotary cylinder is assembled and connected to the inner side of the gantry frame, and a drive gear is assembled and connected to one end of the rotary cylinder shaft. A driven gear is meshed and connected to the bottom of the drive gear. The driven gear is integrally formed on the surface of the sector plate away from the arc plate.

[0012] In one possible implementation, a blocking rack is provided at the bottom of the driven gear, and threaded rods are welded to the bottom of both ends of the blocking rack. A spring is sleeved to the outside of the threaded rod. Movable windows are provided on both sides of the bearing support. The bottom of the threaded rod passes through the interior of the bearing support and is threaded to a nut at the movable window, so that the spring is supported between the bottom of the blocking rack and the top of the bearing support.

[0013] In one possible implementation, the detection head of the tension gauge is threadedly connected to a connecting sleeve, one end of which is welded to a paper guide strip, and the inside of the paper guide strip has an arc-shaped groove; the release paper passes through the inside of the arc-shaped groove, along the top surface of the paper wheel frame, and enters between the inner wall of the pressure plate and the arc plate.

[0014] In one possible implementation, a paper baffle is integrally formed on the top of the paper guide strip. A paper pressure plate is provided on the side of the paper baffle away from the suspension frame. A rubber sheet is fixedly connected to the bottom surface of the paper pressure plate facing the paper baffle. Two limiting rods are welded to the top surface of the paper pressure plate facing the paper baffle. A pressing screw is provided between the two limiting rods, passing through the inside of the paper pressure plate and threadedly connected to the paper baffle. Both limiting rods are slidably connected inside the paper baffle.

[0015] In one possible implementation, the top of both ends of the suspension frame are welded to limit posts, and the middle of the limit posts is integrally formed with a drive plate. The cross-section of the drive plate is a right trapezoid. The bottom slope of the drive plate is adapted to the contact area of ​​the paper sheet baffle and the paper sheet guide strip. The limit posts and the drive plate are slidably connected inside the gantry frame.

[0016] In one possible implementation, the bearing support has pin-connected limiting rods at both ends, limiting grooves are formed inside both environmental simulation components, and rib grooves are formed on the bottom surfaces of both sides of the bearing support. Limiting ribs are integrally formed on the bottom inner walls of both sides of the simulator frame. Both environmental simulation components are movably connected to the inside of the gantry frame, and the simulator frame is slidably connected to the outside of the limiting rods through the limiting grooves. The limiting ribs are slidably connected to the inside of the rib grooves.

[0017] The beneficial effects of this application are as follows: Firstly, in this solution, one end of the release paper is passed between the arc surface of the paper roll frame and the inner wall of the arc plate. A second electric push rod controls the side of the pressure plate facing the suspension frame to move closer to the arc plate, clamping and fixing the release paper. A rotary cylinder controls the rotation of the drive gear, which in turn drives the driven gear to rotate the sector plate, thereby causing the entire paper roll guide frame to rotate outside the paper roll frame. This pulls one end of the release paper around the bottom of the paper roll frame. Then, the first electric push rod controls the paper roll frame to move downwards via the suspension frame, squeezing the release paper between the paper roll frame and the liquid adhesive. After the paper roll frame retracts a certain distance upwards, the tension can be controlled... The release paper is pulled away from the paper baffle, supported by the paper roller frame, and gradually peeled off from the surface of the liquid adhesive. This allows for observation of the peeling resistance from the values ​​displayed on the tension gauge, ultimately enabling analysis and judgment of the release paper's performance at the target temperature. This helps address the issue that when the release paper is directly attached to the surface of the adhesive, it can easily affect the change in the contact area between the release paper and the adhesive, ultimately leading to an increase or decrease in the peeling resistance of the release paper on the adhesive surface, thus reducing measurement accuracy (mainly manifested in the paper roller frame pressing the release paper to the top of the liquid adhesive at the bottom, accompanied by slight deformation of the liquid adhesive, ensuring a fixed contact effect between the adhesive and the paper). Secondly, in this solution, the release paper is fixed between the inner wall of the pressure plate and the inner wall of the paper wheel frame by passing through the inside of the arc-shaped groove and along the top surface of the paper wheel frame. The paper guide frame rotates outside the paper wheel frame, and after one end of the release paper passes between the bottom of the paper wheel frame and the top of the liquid adhesive, the release paper is cut. The other end of the release paper is pressed by the paper pressure plate with the help of the rubber sheet on the surface of the paper baffle. This makes it easier to pull the paper guide strip away from the paper baffle by controlling the tension gauge, thereby pulling the release paper that has passed through the arc-shaped groove.

[0020] The technical solution in this application embodiment is to solve the problems mentioned in the background art, and the overall idea is as follows:

[0021] Example 1 describes the specific structure of a performance testing device for release paper. See attached image for details. Figures 1-6 , Figure 9 and Figure 10 As shown, the system includes an environmental simulation component 1 and a paper fixing component 2 disposed inside the environmental simulation component 1. The environmental simulation component 1 includes a support 103. Two simulator frames 101 that interlock with each other are disposed on the outside of the support 103. A vertically arranged gantry 104 is assembled and connected to the surface of the support 103. A first electric push rod 106 is assembled and connected to the center of the top of the gantry 104. The movable end of the first electric push rod 106 passes through the interior of the gantry 104 and is assembled and connected to a suspension frame 109. Liquid adhesive 6 is disposed inside the support 103. The paper fixing assembly 2 includes a paper wheel frame 201, a paper guide frame 208 is rotatably connected to the outside of the paper wheel frame 201, the paper guide frame 208 includes an arc plate 2082, both ends of the arc plate 2082 are integrally formed with fan-shaped plates 2081, a clamping member 216 is hinged to the side of the arc plate 2082 away from the suspension frame 109, a seat bar 203 is assembled and connected to the inner wall of the top side of the gantry frame 104, and a tension gauge 202 is provided on the side of the seat bar 203 away from the gantry frame 104; The clamping member 216 includes a pressing plate 2161. The top of the pressing plate 2161 away from the suspension frame 109 is integrally formed with a corner piece 2162. One end of the corner piece 2162 is integrally formed with a stop strip 2163. The arc surface of the paper wheel frame 201 is provided with a movable corner groove 4. The suspension frame 109 is assembled and connected to the top of the paper wheel frame 201. The end of the fan-shaped plate 2081 away from the arc plate 2082 is coaxially assembled with the paper wheel frame 201. The corner piece 2162 is hinged to the top of the arc plate 2082 away from the suspension frame 109 via a shaft. A torsion spring 220 is sleeved on the outside of the shaft. The torsion spring 220 is supported between the stop strip 2163 and the outer surface of the arc plate 2082. The pressure plate 2161 is movably connected to the inside of the movable corner groove 4. When one end of the release paper is clamped between the inner wall of the arc plate 2082 and the clamping member 216, and the paper guide frame 208 rotates around the bottom of the paper wheel frame 201 outside the paper wheel frame 201, the release paper strip can pass between the liquid adhesive 6 and the surface of the paper wheel frame 201. Meanwhile, as the movable end of the first electric push rod 106 moves to the bottom and the paper wheel frame 201 moves to the bottom using the suspension frame 109, the paper wheel frame 201 is movably connected between the two simulator frames 101 and is movably connected to the inside of the support 103. The release paper is squeezed between the paper wheel frame 201 and the liquid adhesive 6. After being pressed, the liquid adhesive 6 deforms inside the support 103 and adapts to the bottom surface of the paper wheel frame 201, so that the adhesive is adhered between the support 103 and the release paper. Secondly, to facilitate the clamping member 216 overcoming the resistance of the torsion spring 220, one end of the pressure plate 2161 abuts against the inner wall of the movable corner groove 4, allowing one end of the release paper to quickly pass between the inner wall of the arc plate 2082 and the clamping member 216, such as... Figure 2 , Figure 5 , Figure 7 and Figure 9 As shown, a push rod seat 214 is welded to the outer wall of the arc plate 2082 away from the clamping member 216. A second electric push rod 209 is hinged between the push rod seat 214 and the corner piece 2162. By using the second electric push rod 209 between the push rod seat 214 and the corner piece 2162, when the release paper is not placed between the paper wheel frame 201 and the liquid adhesive 6, its movable end is retracted into the interior of the fixed end. After the clamping member 216 rotates around its hinge point with the arc plate 2082, it remains in a fixed state (i.e., one end of the pressure plate 2161 abuts against the inner wall of the movable corner groove 4). This ensures that the space between the side of the pressure plate 2161 facing the suspension frame 109 and the inner wall of the arc plate 2082 is large enough, and does not affect the release paper from entering between the pressure plate 2161 and the arc plate 2082 along the top surface of the paper wheel frame 201. Furthermore, to facilitate control of the paper guide 208 rotating outside the paper wheel frame 201, the paper guide 208 engages with the clamping member 216, pulling one end of the release paper around the bottom of the paper wheel frame 201, waiting for the release paper to be adhered to the surface of the liquid adhesive 6, such as... Figure 3 and Figure 4As shown, a rotary cylinder 212 is assembled and connected to the inner side of the gantry frame 104. A drive gear 213 is assembled and connected to one end of the rotating shaft of the rotary cylinder 212. A driven gear 211 is meshed and connected to the bottom of the drive gear 213. By integrally forming the driven gear 211 on the surface of the sector plate 2081 away from the arc plate 2082, when the rotary cylinder 212 controls the drive gear 213 to rotate, it can drive the driven gear 211 to drive the sector plate 2081 to rotate, thereby driving the entire paper guide frame 208 to rotate outside the paper wheel frame 201. This is beneficial for using the clamping member 216 and the paper guide frame 208 to pull the release paper around the bottom of the paper wheel frame 201. Meanwhile, to assist in fixing the paper guide frame 208 to the top, and to provide a base for the release paper to enter between the pressure sheet 2161 and the arc plate 2082 along the top surface of the paper wheel frame 201, such as... Figure 5 and Figure 6 As shown, a magnet 108 is embedded in the side of the suspension frame 109 facing the paper guide frame 208. By adapting the top corner of the side of the paper guide frame 208 facing the suspension frame 109 to one side of the suspension frame 109, after the magnet 108 and the threaded upright 215 are attracted and connected, the paper guide frame 208 can be restricted from rotating outside the paper wheel frame 201 when the driven gear 211 on the sector plate 2081 is not meshed with the driving gear 213. Furthermore, to ensure that after the rotary cylinder 212 controls the paper guide frame 208 to rotate via the drive gear 213 and driven gear 211 to complete the traction of the release paper, the driven gear 211 will not disengage from the drive gear 213 due to the first electric push rod 106 controlling the paper wheel frame 201 to move downwards via the suspension frame 109, thus preventing the paper guide frame 208 from being difficult to fix to the outside of the paper wheel frame 201. Figure 3 and Figure 4 As shown, a blocking rack 210 is provided at the bottom of the driven gear 211. Threaded rods 215 are welded to the bottom of both ends of the blocking rack 210. Springs 207 are sleeved onto the outside of the threaded rods 215. Movable windows 5 are provided on both sides of the bearing support 103. By allowing the bottom of the threaded rods 215 to pass through the interior of the bearing support 103 and threading nuts to the movable windows 5, the springs 207 are supported by the bottom of the blocking rack 210 and the bearing support. Between the top of 103, when the first electric push rod 106 controls the paper wheel frame 201 to move to the bottom through the suspension frame 109, and drives the paper guide frame 208 on the paper wheel frame 201 to move to the bottom, so that the driven gear 211 disengages from the driving gear 213, the driven gear 211 immediately meshes with the top of the blocking rack 210, and the blocking rack 210 restricts the rotation of the driven gear 211, thereby restricting the paper guide frame 208 from rotating outside the paper wheel frame 201; Meanwhile, when the first electric push rod 106 controls the paper wheel frame 201 to move to the bottom through the suspension frame 109, and drives the paper guide frame 208 on the paper wheel frame 201 to move to the bottom, the blocking rack 210 moves to the bottom along with the driven gear 211 on the paper guide frame 208, and compresses the spring 207. The blocking rack 210 restricts the rotation of the driven gear 211, keeping the paper guide frame 208 outside the paper wheel frame 201, so as not to affect the subsequent release paper performance test; In some examples, the inner ends of the support 103 are connected by pins to limit rods 102, the inner ends of the two environmental simulation components 1 are provided with limit grooves 3, the bottom surfaces of both sides of the support 103 are provided with rib grooves 7, and the bottom inner walls of both sides of the simulator frames 101 are integrally formed with limit ribs 110. In this configuration, by movably connecting both environmental simulation components 1 to the inside of the gantry 104, and by slidingly connecting the simulator frame 101 to the outside of the limiting rod 102 via the limiting groove 3, and by slidingly connecting the limiting rib 110 to the inside of the rib groove 7, when the two simulator frames 101 are fastened to the top of the support 103, a space where air does not flow easily can be formed between the simulator frame 101 and the support 103, which is convenient for simulating the working environment of release paper. Meanwhile, by controlling the two simulator frames 101 to move away from each other under the guidance of the limiting rod 102, the limiting groove 3, the rib groove 7, and the limiting rib 110, the liquid adhesive 6 on the bearing support 103 can be exposed to the outside, which is conducive to the cleaning and filling of the liquid adhesive 6.

[0022] In this embodiment, the second electric push rod 209 is used to control the clamping member 216 to rotate around the hinge point between it and the arc plate 2082 and tighten the torsion spring 220, so that one end of the pressure plate 2161 abuts against the inner wall of the movable corner groove 4, keeping the side surface of the pressure plate 2161 facing the arc plate 2082 in contact with the arc surface of the paper wheel frame 201. With one end of the release paper passing between the arc surface of the paper wheel frame 201 and the inner wall of the arc plate 2082, the movable end of the second electric push rod 209 extends out, controlling the clamping member 216 to rotate around the hinge point between it and the arc plate 2082, causing the pressure plate 2161 facing the suspension frame 109 to move closer to the arc plate 2082, thus clamping and fixing the release paper. Subsequently, the rotary cylinder 212 controls the drive gear 213 to rotate, driving the driven gear 211 to rotate the sector plate 2081, thereby causing the entire paper guide frame 208 to rotate outside the paper wheel frame 201. One end of the release paper is pulled around the bottom of the paper wheel frame 201. During the process of the first electric push rod 106 controlling the paper wheel frame 201 to move to the bottom using the suspension frame 109, the paper guide frame 208 on the paper wheel frame 201 drives the driven gear 211 to disengage from the drive gear 213 and immediately engages with the top of the blocking rack 210. The blocking rack 210 restricts the rotation of the driven gear 211, thereby restricting the rotation of the paper guide frame 208 outside the paper wheel frame 201. When the first electric push rod 106 controls the paper wheel frame 201 to continue moving downwards, the release paper is squeezed between the paper wheel frame 201 and the liquid adhesive 6. As the liquid adhesive 6 deforms inside the support 103 and adapts to the bottom surface of the paper wheel frame 201, the adhesive adheres to the support 103 and the release paper. Then, the paper wheel frame 201 is retracted a certain distance upwards to release the pressure on the liquid adhesive 6. Finally, the release paper can be pulled away from the paper baffle 205 by controlling the tension gauge 202. The release paper is supported by the paper wheel frame 201 and gradually peels off from the surface of the liquid adhesive 6. The peeling resistance can be observed from the value displayed on the tension gauge 202. Finally, the performance of the release paper at the target temperature can be analyzed and judged.

[0023] Example 2, based on Example 1, describes the specific structure of the tension gauge 202, as follows: Figures 1 to 3 , Figures 6 to 8 As shown, the detection head of the tension gauge 202 is threadedly connected to a connecting sleeve 219, and one end of the connecting sleeve 219 is welded to a paper guide strip 204. The paper guide strip 204 has an arc-shaped groove 8 inside. The top of the paper guide strip 204 is integrally formed with a paper baffle 205. A paper pressure plate 206 is provided on the side of the paper baffle 205 away from the suspension frame 109. A rubber sheet 218 is fixedly connected to the bottom surface of the paper pressure plate 206 facing the paper baffle 205. Two limiting short rods 217 are welded to the top surface of the paper pressure plate 206 facing the paper baffle 205. A pressing screw 221 is provided between the two limiting short rods 217, passing through the inside of the paper pressure plate 206 and threadedly connected to the paper baffle 205. In this process, when the release paper is placed from top to bottom with the help of the paper sheet baffle 205, and passes through the inside of the arc-shaped groove 8 along the top surface of the paper sheet wheel frame 201, and enters the space between the pressure sheet 2161 and the inner wall of the arc plate 2082, the placement of the release paper can be guided efficiently. Secondly, the two limiting short rods 217 are slidably connected inside the paper baffle 205. One end of the release paper is clamped between the pressure plate 2161 and the arc plate 2082. After the paper wheel frame 201 completes the laying work, the other end of the release paper is cut off on one side of the paper baffle 205. Based on the threaded connection between the adjusting pressing screw 221 and the paper baffle 205, the paper pressure plate 206 presses the release paper onto the surface of the paper baffle 205 with the help of the rubber sheet 218 to achieve fixation. Meanwhile, when the first electric push rod 106 controls the paper wheel frame 201 to move downward through the suspension frame 109, so that the surface of the release paper is in contact with the surface of the liquid adhesive 6 and the liquid adhesive 6 undergoes a certain degree of deformation, the paper wheel frame 201 is retracted to the top a certain distance to release the pressure on the liquid adhesive 6. At this time, by controlling the tension gauge 202 to pull the release paper away from the paper baffle 205 (the tension gauge 202 has threaded rods on both sides of the detection head that are connected to the inside of the tension gauge 202, and the rods are slidably connected to the inside of the seat bar 203), the release paper is supported by the paper wheel frame 201 and gradually peels off from the surface of the liquid adhesive 6. The peeling resistance can be observed from the value displayed on the tension gauge 202. Finally, the performance changes of the release paper after the temperature environment affects the liquid adhesive 6 and the release paper are analyzed. Furthermore, to reduce the likelihood of the release paper becoming relatively loose after passing over the bottom of the paper roll frame 201 due to its long length, such as... Figures 6 to 8 As shown, the top of both ends of the suspension frame 109 are welded to limit rods 105. A drive plate 107 is integrally formed in the middle of the limit rod 105. The cross-section of the drive plate 107 is a right-angled trapezoid. The bottom slope of the drive plate 107 is adapted to the contact area between the paper sheet baffle 205 and the paper sheet guide strip 204. Both the limit rods 105 and the drive plate 107 are slidably connected inside the gantry frame 104. When the first electric push rod 106 controls the paper sheet wheel 2 through the suspension frame 109... When the release paper moves to the bottom and is pressed on top of the liquid adhesive 6, the suspension frame 109 drives the driving plate 107 on the limiting rod 105 to apply pressure to the paper baffle 205 and the paper guide strip 204. Since the two ends of the release paper are clamped and fixed by the paper pressure plate 206, the paper baffle 205, the pressure plate 2161 and the arc plate 2082 respectively, the release paper can be tightened and made to conform to the arc surface of the paper wheel frame 201 when the paper baffle 205 and the paper guide strip 204 are pressed to one side.

[0024] In this embodiment, the release paper is blocked from top to bottom by the paper sheet baffle 205, passes through the inside of the arc groove 8 along the top surface of the paper sheet wheel frame 201, and is fixed between the inner wall of the pressure plate 2161 and the arc plate 2082. The paper sheet guide frame 208 rotates outside the paper sheet wheel frame 201. After one end of the release paper is pulled through the bottom of the paper sheet wheel frame 201 and the top of the liquid adhesive 6, the release paper is cut, and the other end is pressed by the paper sheet pressure plate 206 on the surface of the paper sheet baffle 205 by the rubber sheet 218. Meanwhile, as the first electric push rod 106 controls the paper wheel frame 201 to move downward through the suspension frame 109, so that the release paper is pressed on the top of the liquid adhesive 6, the suspension frame 109 drives the drive plate 107 on the limit rod 105 to apply pressure to the paper baffle 205 and the paper guide strip 204. Since the two ends of the release paper are respectively clamped and fixed by the paper pressure plate 206 and the paper baffle 205, the pressure plate 2161 and the arc plate 2082, the release paper can be tightened when the paper baffle 205 and the paper guide strip 204 are pressed to one side, so that it fits the arc surface of the paper wheel frame 201. This is beneficial because the release paper is relatively long and becomes relatively loose after passing around the bottom of the paper wheel frame 201, which affects the adhesion between the release paper and the surface of the liquid adhesive 6. Finally, the tension gauge 202 is controlled to pull the paper guide strip 204 away from the paper baffle 205, thereby pulling the release paper that passes through the arc groove 8 to move. This is beneficial for testing the peel resistance of the paper wheel frame 201 from the top surface of the liquid adhesive 6, thereby testing the performance of the release paper.

[0025] Specifically, when using this performance testing device for release paper: First, the second electric push rod 209 controls the clamping member 216 to rotate around the hinge point between it and the arc plate 2082 and tightens the torsion spring 220, so that one end of the pressure plate 2161 abuts against the inner wall of the movable corner groove 4, keeping the side surface of the pressure plate 2161 facing the arc plate 2082 in contact with the arc surface of the paper wheel frame 201. The release paper is blocked from top to bottom by the paper baffle 205 and passes through the inside of the arc groove 8 along the top surface of the paper wheel frame 201, entering between the pressure plate 2161 and the inner wall of the arc plate 2082. The second electric push rod 209 controls the clamping member 216 to rotate around the hinge point between it and the arc plate 2082, so that the side of the pressure plate 2161 facing the suspension frame 109 moves closer to the arc plate 2082, clamping and fixing the release paper. Then, the rotary cylinder 212 controls the drive gear 213 to drive the driven gear 211 to rotate the sector plate 2081, thereby causing the entire paper guide frame 208 to rotate outside the paper wheel frame 201. One end of the release paper is pulled around the bottom of the paper wheel frame 201. During the process of the first electric push rod 106 controlling the paper wheel frame 201 to move to the bottom using the suspension frame 109, the paper guide frame 208 on the paper wheel frame 201 drives the driven gear 211 to disengage from the drive gear 213 and immediately engage with the top of the blocking rack 210. The blocking rack 210 restricts the rotation of the driven gear 211, thereby restricting the rotation of the paper guide frame 208 outside the paper wheel frame 201. Next, the release paper is cut on the side of the paper baffle 205 away from the hanging frame 109, so that the end of the release paper is pressed against the surface of the paper baffle 205 by the paper pressure plate 206 with the help of the rubber sheet 218. Subsequently, the first electric push rod 106 controls the paper wheel frame 201 to continue moving to the bottom, so that the release paper is squeezed between the paper wheel frame 201 and the liquid adhesive 6. As the liquid adhesive 6 deforms inside the support 103 and adapts to the bottom surface of the paper wheel frame 201, the adhesive adheres between the support 103 and the release paper. Then, the paper wheel frame 201 is retracted to the top by a certain distance to release the pressure on the liquid adhesive 6. At the same time, the movable end of the second electric push rod 209 moves inward a certain distance towards the fixed end, controlling the clamping member 216 to rotate around the hinge point between it and the arc plate 2082, so that the release paper can move between the arc plate 2082 and the pressure plate 2161. Finally, the tension gauge 202 is controlled to pull the paper guide strip 204 away from the paper baffle 205, thereby pulling the release paper passing through the arc groove 8 to move, so that the release paper is supported by the paper wheel frame 201 and gradually peels off from the surface of the liquid adhesive 6. The peeling resistance can be observed from the value displayed on the tension gauge 202, and the performance of the release paper at the target temperature can be analyzed and judged.

[0026] It is worth noting that, in order to make the resistance encountered by the release paper in separating from the liquid adhesive 6 more obvious, when the liquid adhesive 6 is pasted between the support 103 and the release paper, the paper wheel frame 201 is no longer allowed to retract a certain distance to the top, and pressure is maintained on the liquid adhesive 6. At this time, it is only necessary to measure the maximum friction between the release paper and the liquid adhesive 6 and the support 103 (the friction between the release paper and the smooth arc surface of the paper wheel frame 201 is ignored).

[0027] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
