Description

Technical Field

[0001] This invention relates to the field of testing technology, specifically to a peel force testing machine. Background Technology

[0002] A peel strength tester is a professional testing instrument for accurately measuring the adhesive strength of materials. Also known as a peel strength tester, it is mainly used to quantify the bonding and peel performance of materials such as tapes, protective films, composite films, and coatings. It is a core piece of equipment for R&D and quality control in industries such as adhesives, packaging, electronics, and automobiles. The peel strength tester can effectively detect whether materials have problems such as weak adhesion, delamination, or peeling, thus controlling product quality from the source and reducing the risk of failure during use.

[0003] This equipment is based on mechanical transmission, force sensing, and data processing. It achieves uniform loading through a servo motor and ball screw, and is equipped with high-precision force and displacement sensors to collect force and displacement data in real time during the peeling process. During testing, the sample is fixed in a special fixture according to the standard, and peeling angles such as 90°, 180°, and T-shaped are selected. A constant peeling speed is set, and the equipment automatically completes the peeling action and generates force and displacement curves. It accurately calculates key indicators such as average peeling force and peak peeling force, objectively reflecting the bonding reliability.

[0004] In existing vertical peel force testing machines, the conversion process from vertical peel to lateral peel (90° / 180°) is extremely cumbersome and relies entirely on manual operation. The core drawback of the conversion process is its complexity, lack of quick-change and precise positioning capabilities. When switching, it is necessary to completely disassemble the components required for vertical peel, such as clamps, connecting rods, and guide seats, and then install the scattered parts such as the steering bracket, pulley block, and lateral clamps specifically for lateral peel one by one. There are many fasteners, and a single disassembly and assembly takes as long as 10-30 minutes, making the operation extremely cumbersome. At the same time, there is no standardized positioning benchmark or quick-change mechanism. After each installation, it is necessary to manually and repeatedly adjust the levelness, center line alignment, and peel angle. The adjustment depends on the operator's experience, which increases the operator's workload. Summary of the Invention

[0005] Therefore, the purpose of this invention is to provide a peel force testing machine to solve the technical problems in the background art mentioned above.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a peel force testing machine, comprising a testing machine body, a mounting column, and an operating block, wherein the mounting column is mounted on the upper end of the testing machine body, and the operating block is movably mounted on the upper end of the testing machine body;

[0007] The upper end of the main body of the testing machine is provided with a first slide rail, the inner wall of the first slide rail is symmetrically provided with a first groove, a first placement plate is movably installed inside the first slide rail, a plurality of first clamping plates are movably installed on one side of the first placement plate, damping shafts are symmetrically installed on the outer wall of the first placement plate, and two sets of damping shafts are respectively movably connected to two sets of first grooves. A third slide rail is provided on one side of the mounting column, a second placement plate is movably installed on the inner wall of the third slide rail, and a second clamping plate is movably installed on one side of the second placement plate.

[0008] The upper part of the main body of the testing machine is provided with a second slide rail, and the width of the second slide rail is smaller than that of the first slide rail. A push plate is movably installed at one end of the second slide rail, and the operating block is movably connected to a set of damping rotating shafts.

[0009] The main body of the testing machine is equipped with a control panel at one end. A drive motor is installed inside the main body of the testing machine, and the control panel is electrically connected to the drive motor. A drive shaft is installed at the output end of the drive motor, and the drive shaft is movably connected to the first placement plate and the second placement plate.

[0010] By adopting the above technical solution, the problem of converting vertical peeling to horizontal peeling (° / °) is solved. As a key component for manual operation, the operating block allows operators to complete the mode conversion simply by pushing the operating block, without the need for complex disassembly or debugging. This simplifies the operation process, reduces the difficulty of manual operation, and improves test efficiency. The damping shaft, as the core component for flipping, supports the first placement plate to achieve smooth flipping. It can be precisely adjusted to the required angle for horizontal peeling at ° or °, and the damping characteristics can achieve positioning and locking after flipping. Then, the push plate pushes the first placement plate to move, and one end of the push plate is in close contact with one end of the first placement plate to prevent the first placement plate from shaking or rebounding during the test, ensuring the stability of the product angle during horizontal peeling and improving the accuracy of test data.

[0011] The present invention is further configured such that multiple sets of mounting plates are installed on the outer wall of the first placement plate, and a first limiting shaft is movably installed on the inner wall of each of the multiple sets of mounting plates. One end of each of the multiple sets of first limiting shafts extends into the interior of the first placement plate. The outer walls of the multiple sets of first limiting shafts are threadedly connected to the inner walls of the multiple sets of first clamping plates, and toothed synchronous belts are provided between the multiple sets of first limiting shafts. A first torsion block is installed on one end of the first limiting shaft extending to the outer wall of the mounting plate.

[0012] Preferably, rotating the first torsion block drives a set of first limiting shafts to rotate. The multiple sets of first limiting shafts are connected to each other by toothed synchronous belts, so the multiple sets of first limiting shafts rotate synchronously. The outer walls of the multiple sets of first limiting shafts are threadedly connected to the inner walls of the multiple sets of first clamping plates, so the multiple sets of first clamping plates are displaced.

[0013] The present invention is further configured such that two sets of second limiting shafts are movably installed on the inner wall of the second placement plate, and the two sets of second limiting shafts are connected by a toothed synchronous belt. The outer walls of the two sets of second limiting shafts are threadedly connected to the inner wall of the second clamping plate. A second torsion block is installed on one end of the second limiting shaft extending to the outer wall of the second placement plate.

[0014] Preferably, rotating the second torsion block drives a set of second limiting shafts to rotate. The two sets of second limiting shafts are connected by a toothed synchronous belt, so the two sets of second limiting shafts rotate synchronously. The outer walls of the two sets of second limiting shafts are threadedly connected to the inner wall of the second clamping plate, so the second clamping plate is displaced.

[0015] The present invention is further configured such that a first connecting shaft is movably installed inside the mounting column, and two sets of sprockets are installed on the outer walls of both the drive shaft and the first connecting shaft. Chains are provided between the multiple sets of sprockets, and the outer walls of both sets of chains are fixedly connected to the inner wall of the second placement plate.

[0016] Preferably, the drive shaft rotates, thereby driving the two sets of sprockets to rotate. The two sets of sprockets on the outer wall of the drive shaft and the two sets of sprockets on the outer wall of the first connecting shaft are connected by chains. Therefore, when the first connecting shaft rotates, the two sets of chains operate, thereby driving the second placement plate to move.

[0017] The present invention is further configured such that a third slide groove is provided on one side of the main body of the testing machine, and an installation groove is provided on one side of the operating block. A movable plate is movably installed inside the installation groove, and the outer wall of the movable plate is movably connected to the inner wall of the third slide groove. A first toothed plate is installed at one end of the movable plate, and a damping gear is installed on the outer wall of a set of damping shafts, and the first toothed plate is meshed with the damping gear.

[0018] Preferably, the operating block is displaced, thereby causing the movable plate to be displaced, which in turn causes the first toothed plate to be displaced. The first toothed plate is meshed with the damping gear, so the damping gear rotates, thereby causing the damping shaft to rotate, which in turn causes the first placement plate to rotate around the damping shaft, so that the first placement plate flips and enters the first slide.

[0019] The present invention is further configured such that a fourth sliding groove is provided at the upper end of the main body of the testing machine, a second toothed plate is installed inside the fourth sliding groove, a movable shaft is movably installed inside the mounting groove, and a movable gear is installed at one end of the movable shaft extending into the fourth sliding groove, and the movable gear is meshed with the second toothed plate.

[0020] Preferably, the operating block is displaced, causing the movable gear to move to one side of the second toothed plate. The movable gear meshes with the second toothed plate, and the movable gear rotates, thereby causing the movable shaft to rotate. The outer wall of the movable shaft meshes with the inner wall of the movable plate, so the movable plate moves downward, thereby causing the first toothed plate to move downward, thus avoiding interference between the first toothed plate and the movement of the first placement plate in the subsequent test stage.

[0021] The present invention is further configured such that a first engagement groove is provided at one end of the drive shaft, a first engagement block is movably installed inside the first engagement groove, a first transmission shaft is installed at one end of the first engagement block, a reserved groove is provided on the outer wall of the first transmission shaft, and a second engagement groove is provided at one end of the first transmission shaft.

[0022] Preferably, the drive shaft rotates, causing the first engaging block to rotate, which in turn causes the first transmission shaft to rotate.

[0023] The present invention is further configured such that a fifth sliding groove is provided at the upper end of the main body of the testing machine, an installation rod is installed at the bottom end of the operating block, and the outer wall of the installation rod is movably connected to the inner wall of the fifth sliding groove. A sleeve is installed at one end of the installation rod, and the inner wall of the sleeve is movably connected to the outer wall of the reserved groove.

[0024] Preferably, the operating block is displaced, thereby causing the mounting rod to be displaced, which in turn causes the sleeve to be displaced, and subsequently causes the first drive shaft to be displaced.

[0025] The present invention is further configured such that a second drive shaft is movably installed inside the main body of the testing machine, a second locking block is installed at one end of the second drive shaft, and the outer wall of the second locking block is threadedly connected to the inner wall of the second locking groove. The cross sections of the first locking groove, the first locking block, the second locking groove, and the second locking block are all hexagonal.

[0026] Preferably, the displacement of the first drive shaft causes the displacement of the second engagement groove, which then fits onto the outer wall of the second engagement block, connecting the drive shaft, the first drive shaft, and the second drive shaft. The hexagonal cross-sections of the first engagement groove, the first engagement block, the second engagement groove, and the second engagement block enhance the ease of engagement between them. If the engagement of the second engagement groove and the second engagement block becomes stuck and the connection fails, the operator can start the drive motor via the control panel to adjust the angle of the second engagement groove.

[0027] The present invention is further configured such that the inner wall of the second slide is symmetrically provided with second slide grooves, and the inner walls of the two sets of second slide grooves are movably installed with second connecting shafts, and a toothed synchronous belt is provided between one set of second connecting shafts and the second transmission shaft. The outer walls of the two sets of second connecting shafts are respectively threaded to the inner walls of both ends of the push plate, and a toothed synchronous belt is provided between the two sets of second connecting shafts.

[0028] Preferably, the second drive shaft rotates, and the second drive shaft is connected to a set of second connecting shafts by a toothed synchronous belt. Therefore, the set of second connecting shafts rotates, and the two sets of second connecting shafts are connected by a toothed synchronous belt, so the two sets of second connecting shafts rotate synchronously. The outer walls of the two sets of second connecting shafts are threaded to the inner walls of both ends of the push plate, so the push plate is displaced.

[0029] In summary, the present invention has the following main beneficial effects:

[0030] 1. This invention solves the problem of switching from vertical peeling to horizontal peeling (90° / 180°) by setting up a first placement plate, a damping shaft, an operating block, and a push plate. The operating block is a key component for manual operation. The operator only needs to push the operating block to complete the mode switch without complicated disassembly or debugging, which simplifies the operation process, reduces the difficulty of manual operation, and improves the efficiency of the test. The damping shaft is the core component for flipping. It supports the first placement plate to achieve smooth flipping and can be accurately adjusted to the angle required for horizontal peeling of 90° or 180°. Moreover, the damping characteristics can achieve positioning and locking after flipping. Then, the push plate pushes the first placement plate to move. One end of the push plate is in close contact with one end of the first placement plate to prevent the first placement plate from shaking or rebounding during the test, ensuring the stability of the product angle during horizontal peeling and improving the accuracy of the test data.

[0031] 2. This invention, by incorporating a drive shaft, a first connecting shaft, a sprocket, a chain, and a second placement plate, effectively solves the transmission defects existing in current peel force testing equipment, significantly improving test stability and data accuracy. In existing technologies, most peel force testing equipment uses a threaded connection to drive the lifting of the test component. During thread engagement, noticeable abnormal noise can easily occur due to tooth surface wear, excessive clearance, or insufficient lubrication. Furthermore, the rigidity of the threaded transmission is insufficient, leading to jamming and vibration during operation. This results in uneven lifting speed of the test component, poor stability, and consequently, fluctuations in the peel force, affecting the accurate acquisition of test data by the control panel and failing to meet high performance requirements. To meet the requirements of precision peeling tests, the drive shaft is set as the core of power output, accurately transmitting the power of the drive motor. It works in conjunction with the first connecting shaft to achieve power splitting and synchronous transmission. The transmission mechanism composed of sprockets and chains has strong transmission rigidity, small gaps, no obvious abnormal noise during operation, and high transmission efficiency, which can effectively avoid the jamming and vibration problems of threaded transmission. At the same time, the two sets of sprockets and chains work together to drive the second placement plate to move at a uniform speed and smoothly, ensuring that the end of the material to be peeled is subjected to uniform force and stable displacement during the lifting process, avoiding material slippage or abnormal force due to unstable lifting, thus improving the stability, quietness and data accuracy of the test.

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0048] The embodiments of the present invention will now be described.

[0049] A peel force testing machine, such as Figure 1 - Figure 13 As shown, it includes a testing machine body 1, a mounting column 7 and an operating block 19. The mounting column 7 is installed on the upper end of the testing machine body 1, and the operating block 19 is movably installed on the upper end of the testing machine body 1.

[0050] The upper end of the main body 1 of the testing machine is provided with a first slide rail 3. The inner wall of the first slide rail 3 is symmetrically provided with a first groove 4. A first placement plate 12 is movably installed inside the first slide rail 3. Multiple sets of first clamping plates 18 are movably installed on one side of the first placement plate 12. Damping shafts 13 are symmetrically installed on the outer wall of the first placement plate 12, and the two sets of damping shafts 13 are respectively movably connected to the two sets of first grooves 4. A third slide rail 8 is provided on one side of the mounting column 7. A second placement plate 26 is movably installed on the inner wall of the third slide rail 8. A second clamping plate 29 is movably installed on one side of the second placement plate 26.

[0051] The upper end of the main body 1 of the testing machine is provided with a second slide rail 5, and the width of the second slide rail 5 is smaller than that of the first slide rail 3. A push plate 43 is movably installed at one end of the second slide rail 5. The operating block 19 is movably connected to a set of damping rotating shafts 13. The operator only needs to push the operating block 19 to complete the mode conversion. There is no need for complicated disassembly or debugging, which simplifies the operation process, reduces the difficulty of manual operation, and improves the testing efficiency. The damping rotating shaft 13 is the core component for flipping. It supports the first placement plate 12 to achieve smooth flipping. It can be precisely adjusted to the required angle for lateral peeling of 90 degrees or 180 degrees. Moreover, the damping characteristics can achieve positioning and locking after flipping.

[0052] The main body 1 of the testing machine is equipped with a control panel 2 at one end. The main body 1 of the testing machine is equipped with a drive motor 30, and the control panel 2 is electrically connected to the drive motor 30. The operator starts the drive motor 30 through the control panel 2. The output end of the drive motor 30 is equipped with a drive shaft 31, and the drive shaft 31 is movably connected to the first placement plate 12 and the second placement plate 26.

[0053] Please see Figure 6 - Figure 7 Multiple sets of mounting plates 15 are installed on the outer wall of the first placement plate 12. Each set of mounting plates 15 has a first limiting shaft 17 movably installed on its inner wall. One end of each set of first limiting shafts 17 extends into the interior of the first placement plate 12. The outer walls of each set of first limiting shafts 17 are threadedly connected to the inner walls of each set of first clamping plates 18. Toothed synchronous belts connect the sets of first limiting shafts 17. A first torsion block 16 is installed at one end of each set of first limiting shafts 17 extending to the outer wall of the mounting plate 15. Rotating the first torsion block 16 causes the set of first limiting shafts 17 to rotate. The sets of first limiting shafts 17 are connected to each other by toothed synchronous belts, so the sets of first limiting shafts 17 rotate synchronously. The outer walls of each set of first limiting shafts 17 are threadedly connected to the inner walls of each set of first clamping plates 18, so the sets of first clamping plates 18 are displaced.

[0054] Please see Figure 4 - Figure 10Two sets of second limiting shafts 28 are movably installed on the inner wall of the second placement plate 26, and the two sets of second limiting shafts 28 are connected by a toothed synchronous belt. The outer walls of the two sets of second limiting shafts 28 are threadedly connected to the inner wall of the second clamping plate 29. A second torsion block 27 is installed at one end of the second limiting shaft 28 extending to the outer wall of the second placement plate 26. Rotating the second torsion block 27 drives the second limiting shaft 28 to rotate. The two sets of second limiting shafts 28 are connected by a toothed synchronous belt, so the two sets of second limiting shafts 28 rotate synchronously. The outer walls of the two sets of second limiting shafts 28 are threadedly connected to the inner wall of the second clamping plate 29, so the second clamping plate 29 is displaced.

[0055] Please see Figure 1 - Figure 5 The first connecting shaft 34 is movably installed inside the mounting column 7. Two sets of sprockets 33 are installed on the outer walls of both the drive shaft 31 and the first connecting shaft 34. Chains 35 are provided between the multiple sets of sprockets 33, and the outer walls of the two sets of chains 35 are fixedly connected to the inner wall of the second placement plate 26. When the drive shaft 31 rotates, it drives the two sets of sprockets 33 to rotate. The two sets of sprockets 33 on the outer wall of the drive shaft 31 and the two sets of sprockets 33 on the outer wall of the first connecting shaft 34 are connected by chains 35. Therefore, when the first connecting shaft 34 rotates, the two sets of chains 35 operate, thereby driving the second placement plate 26 to move.

[0056] Please see Figure 2 - Figure 9 The main body 1 of the testing machine is provided with a third slide groove 9 on one side, and an installation groove 20 is provided on one side of the operating block 19. A movable plate 22 is movably installed inside the installation groove 20, and the outer wall of the movable plate 22 is movably connected to the inner wall of the third slide groove 9. A first toothed plate 23 is installed at one end of the movable plate 22. A damping gear 14 is installed on the outer wall of a set of damping shafts 13, and the first toothed plate 23 is meshed with the damping gear 14. When the operating block 19 is displaced, the movable plate 22 is displaced, which in turn causes the first toothed plate 23 to be displaced. The first toothed plate 23 is meshed with the damping gear 14, so the damping gear 14 rotates, which in turn causes the damping shaft 13 to rotate, which in turn causes the first placement plate 12 to rotate around the damping shaft 13, so that the first placement plate 12 flips and enters the first slide groove 3.

[0057] Please see Figure 2 - Figure 9The upper end of the main body 1 of the testing machine is provided with a fourth slide groove 10. A second toothed plate 45 is installed inside the fourth slide groove 10. A movable shaft 21 is movably installed inside the mounting groove 20. A movable gear 44 is installed at one end of the movable shaft 21 that extends into the fourth slide groove 10. The movable gear 44 is meshed with the second toothed plate 45. When the operating block 19 is displaced, it drives the movable gear 44 to move to one side of the second toothed plate 45. The movable gear 44 meshes with the second toothed plate 45 and rotates, thereby driving the movable shaft 21 to rotate. The outer wall of the movable shaft 21 meshes with the inner wall of the movable plate 22, so the movable plate 22 moves downward, thereby driving the first toothed plate 23 to move downward, so as to avoid the first toothed plate 23 interfering with the movement of the first placement plate 12 in the subsequent test stage.

[0058] Please see Figure 11 - Figure 12 The drive shaft 31 has a first engagement groove 32 at one end, a first engagement block 38 is movably installed inside the first engagement groove 32, a first transmission shaft 36 is installed at one end of the first engagement block 38, a reserved groove 37 is opened on the outer wall of the first transmission shaft 36, and a second engagement groove 39 is opened at one end of the first transmission shaft 36. When the drive shaft 31 rotates, it drives the first engagement block 38 to rotate, thereby driving the first transmission shaft 36 to rotate.

[0059] Please see Figure 2 - Figure 9 The upper end of the main body 1 of the testing machine is provided with a fifth slide groove 11. The bottom end of the operating block 19 is equipped with an installation rod 24, and the outer wall of the installation rod 24 is movably connected to the inner wall of the fifth slide groove 11. One end of the installation rod 24 is equipped with a sleeve 25, and the inner wall of the sleeve 25 is movably connected to the outer wall of the reserved groove 37. When the operating block 19 is displaced, it drives the installation rod 24 to be displaced, which in turn drives the sleeve 25 to be displaced, and then drives the first transmission shaft 36 to be displaced.

[0060] Please see Figure 9 - Figure 12The main body 1 of the testing machine has a second drive shaft 40 movably installed inside. A second engaging block 41 is installed at one end of the second drive shaft 40, and the outer wall of the second engaging block 41 is threadedly connected to the inner wall of the second engaging groove 36. The first engaging groove 32, the first engaging block 38, the second engaging groove 38, and the second engaging block 41 are all hexagonal in cross-section. When the first drive shaft 36 is displaced, it drives the second engaging groove 39 to move as well. The second engaging groove 39 fits onto the outer wall of the second engaging block 41, so that the drive shaft 31 and the first drive shaft... The first engaging groove 32, the first engaging block 38, the second engaging groove 38, and the second engaging block 41 are hexagonal in cross-section, which improves the convenience of engaging and connecting the first engaging groove 32, the first engaging block 38, the second engaging groove 38, and the second engaging block 41. If the second engaging groove 38 and the second engaging block 41 jam and fail to engage successfully, the operator can start the drive motor through the control panel 2 to adjust the angle of the second engaging groove 38.

[0061] Please see Figure 2 - Figure 13 The inner wall of the second slide rail 5 is symmetrically provided with second slide grooves 6. The inner walls of the two sets of second slide grooves 6 are movably installed with second connecting shafts 42. One set of second connecting shafts 42 is connected to the second transmission shaft 40 by a toothed synchronous belt. The outer walls of the two sets of second connecting shafts 42 are respectively threaded to the inner walls of both ends of the push plate 43. The two sets of second connecting shafts 42 are connected to each other by a toothed synchronous belt. When the second transmission shaft 40 rotates, the two sets of second connecting shafts 42 are connected to each other by a toothed synchronous belt, so the two sets of second connecting shafts 42 rotate synchronously. The outer walls of the two sets of second connecting shafts 42 are threaded to the inner walls of both ends of the push plate 43, so the push plate 43 is displaced.

[0062] The working principle of this invention is as follows: When the operator uses the equipment to conduct a peel force test, the operator places the test product inside the first placement plate 12, and then the operator rotates the first torsion block 16, which drives a set of first limiting shafts 17 to rotate. The multiple sets of first limiting shafts 17 are connected to each other by toothed synchronous belts, so the multiple sets of first limiting shafts 17 rotate synchronously. The outer walls of the multiple sets of first limiting shafts 17 are threadedly connected to the inner walls of the multiple sets of first clamping plates 18, so the multiple sets of first clamping plates 18 are displaced. The multiple sets of first clamping plates 18 cooperate with the first placement plate 12 to clamp and fix the test product.

[0063] After the test product is clamped and fixed, the staff pulls one end of the material bonded to the outer wall of the test product between the second placement plate 26 and the second clamping plate 29. Then, the staff rotates the second torsion block 27, which drives a set of second limiting shafts 28 to rotate. The two sets of second limiting shafts 28 are connected by a toothed synchronous belt, so the two sets of second limiting shafts 28 rotate synchronously. The outer walls of the two sets of second limiting shafts 28 are threadedly connected to the inner wall of the second clamping plate 29, so the second clamping plate 29 is displaced. The second clamping plate 29 cooperates with the second placement plate 26 to clamp and fix one end of the material.

[0064] After the test product and material are clamped and fixed at one end, the operator starts the drive motor 30 through the control panel 2. The drive motor 30 drives the drive shaft 31 to rotate, which in turn drives the two sets of sprockets 33 to rotate. The two sets of sprockets 33 on the outer wall of the drive shaft 31 and the two sets of sprockets 33 on the outer wall of the first connecting shaft 34 are connected by chains 35. Therefore, the first connecting shaft 34 rotates. At the same time, the two sets of chains 35 operate, which drives the second placement plate 26 to move, and then drives one end of the material to move upward to conduct a peel force test. The control panel 2 collects the peel force data.

[0065] If the operator needs to conduct a lateral peel force test, the operator pushes the operating block 19 to move, thereby moving the movable plate 22, the movable shaft 21, and the movable gear 44, which in turn moves the first toothed plate 23. The first toothed plate 23 meshes with the damping gear 14, so the damping gear 14 rotates, thereby moving the damping shaft 13, which in turn moves the first placement plate 12 around the damping shaft 13, causing the first placement plate 12 to flip and enter the first slide rail 3. The operating block 19 continues to move, moving the movable gear 44 to the side of the second toothed plate 45. The movable gear 44 meshes with the second toothed plate 45, and the movable gear 44 rotates, thereby moving the movable shaft 21. The outer wall of the movable shaft 21 meshes with the inner wall of the movable plate 22, so the movable plate 22 moves downward, thereby moving the first toothed plate 23 downward, avoiding interference from the first toothed plate 23 to the movement of the first placement plate 12 in the subsequent test stage.

[0066] When the operating block 19 is displaced, it drives the mounting rod 24 to be displaced, which in turn drives the sleeve 25 to be displaced. The sleeve 25 drives the first drive shaft 36 to be displaced, causing the first engaging block 38 to be displaced inside the first engaging groove 32. However, one end of the first engaging block 38 is not moved out of the first engaging groove 32. The first drive shaft 36 continues to be displaced, driving the second engaging groove 39 to be displaced. The second engaging groove 39 is fitted onto the outer wall of the second engaging block 41, so that the drive shaft 31, the first drive shaft 36 and the second drive shaft 40 are connected.

[0067] After the operating block 19 moves, the operator clamps and fixes the test product and one end of the material respectively in the above manner. Then, the operator starts the drive motor 30 through the control panel 2, which drives the drive shaft 31, the first transmission shaft 36 and the second transmission shaft 40 to rotate. The second transmission shaft 40 is connected to a set of second connecting shafts 42 by a toothed synchronous belt, so one set of second connecting shafts 42 rotates. The two sets of second connecting shafts 42 are connected by a toothed synchronous belt, so the two sets of second connecting shafts 42 rotate synchronously. The outer walls of the two sets of second connecting shafts 42 are threaded to the inner walls of the two ends of the push plate 43, so the push plate 43 is displaced. The two sets of chains 35 drive the second placement plate 26 to move, thereby moving one end of the material. The push plate 43 pushes the first placement plate 12 to move, thereby moving the test product to perform a peel force test. The control panel 2 collects the peel force data.
