Description

Technical Field

[0001] This utility model relates to the field of testing machine technology, specifically to an angle adjustment device for a peel force testing machine. Background Technology

[0002] A peel force tester is used to test the peel force of adhesive tapes, protective films, release paper, release films, etc. It includes a machine body, a base, an upper clamping section, a lower clamping section, and a terminal for detecting and analyzing peel force. The upper clamping section is equipped with a force sensor. The lower clamping section is fixed to the base, and the upper clamping section can move along its length within the machine body. The machine body has a device for moving the upper clamping section, which can be a screw-driven device or a pneumatic rod driven device. The peel force test includes the following steps:

[0003] The material to be tested, such as tape, is attached to a substrate at one end. The substrate is clamped and fixed using the lower clamping part, and the other end of the material is clamped using the upper clamping part. Then, the peel force tester is started, and the device inside the machine moves the upper clamping part upward, thereby causing the material to peel off. The peel force is monitored using a force sensor and displayed on the terminal.

[0004] In peel force testing, the peel angle is one of the key parameters affecting the test results. The most commonly used peel angles include 90-degree peel (one end of the specimen is stretched perpendicularly) and 180-degree peel (both ends of the specimen are stretched parallel to each other in opposite directions). Currently used peel force testing machines have the following problems in terms of angle adaptability:

[0005] 1. Fixed and Single Angle: Most equipment is only pre-configured with a single angle (usually 90 degrees or 180 degrees) for dedicated peeling fixtures when it leaves the factory. The testing machine itself does not have a convenient angle adjustment function. 2. Reliance on Fixture Replacement: When users need to switch the test angle (for example, from 90 degrees to 180 degrees, or vice versa), the machine must be stopped, the current fixture must be manually removed, and then a dedicated fixture for the target angle must be installed. This process usually involves the operation of multiple fastening screws. 3. Low Efficiency: Frequent fixture replacement operations significantly increase test preparation time and reduce test efficiency, especially in R&D or quality inspection processes that require alternating tests at different angles, where the operation is even more cumbersome. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies by providing an angle adjustment device for a peel force testing machine that improves testing efficiency, ease of operation, and equipment adaptability.

[0007] The objective of this utility model is achieved through the following solution:

[0008] An angle adjustment device for a peel force testing machine includes an upper clamping part and a lower clamping part.

[0009] The upper clamping part includes a top plate, a top frame is fixedly installed on one side of the top plate, a moving block is installed on the top plate through a moving structure, a connecting rod is fixedly installed at the lower end of the moving block, and an upper clamping structure is installed downward on the connecting rod;

[0010] The lower clamping part includes a connecting seat fixedly installed on the base of the testing machine. The connecting seat is connected to the base plate through a rotation limiting structure. The base plate is connected to the slide block through a sliding structure. One end of the slide block is equipped with an end clamping structure. The other end of the slide block is fixedly connected to one end of a rope. The other end of the rope is fixed with a threaded head. The top plate is provided with a threaded hole that mates with the threaded head. One end of the slide block is rotatably equipped with a guide wheel for guiding the rope.

[0011] In this way, the upper and lower clamping parts are used to clamp the material. The angle of the lower clamping part can be switched between 90° and 180° test angles. There is no need to disassemble the lower clamping part, making the operation convenient, time-saving and labor-saving.

[0012] Specifically, the upper clamping part is connected to the device inside the machine body of the testing machine through the top frame. The device inside the machine body drives the upper clamping part to move in the vertical direction, thereby moving the material and realizing peeling.

[0013] When a 90° peel test is required, the rotation limiting structure restricts the base plate to a horizontal position. At this time, the slide is also set horizontally, the threaded head connects to the threaded hole of the top plate, the guide wheel guides the rope, one end of the material is bonded to the substrate, the end clamping structure clamps and fixes the substrate, and the upper clamping structure fixes the other end of the material. The position of the slide and the upper clamping part is adjusted so that the upper part of the material remains vertical and the rope is in a taut state. Then, the testing machine is started, and the device inside the machine body drives the upper clamping part to move upward. Through the setting of the top plate and the rope, the slide is moved synchronously, so that the upper part of the material always remains in a vertical state during the peeling process, ensuring 90° peel and improving the accuracy of the test results.

[0014] When a 180° peel test is required, rotate the base plate to a vertical position and rotate the limiting structure to lock the base plate. At this time, the slide is also in a vertical position, the threaded head disengages from the threaded hole of the top plate, and one end of the material is bonded to the substrate. The substrate is clamped and fixed using the end clamping structure, and the other end of the material is fixed using the upper clamping structure. The position of the moving block is adjusted by the moving structure so that the material is in a folded state and both sides of the material are in a vertical state. Then, start the testing machine. The device inside the machine body drives the upper clamping part to move upward, and the 180° peel test can be performed.

[0015] When switching between 90° peel test and 180° peel test, there is no need to disassemble the lower clamping part. The overall structure is simple and coordinated, making it easy to use.

[0016] Preferably, the movable structure includes upright plates fixedly installed on both sides of the lower end of the top plate and a screw rod rotatably connected to the upright plates. One end of the screw rod is located on the outside of the upright plate and a knob is fixedly installed thereon. The movable block is fixedly installed with a nut that is threadedly engaged with the screw rod. The upper surface of the movable block is slidably attached to the top plate.

[0017] Preferably, the upper clamping structure includes an upper clamping block, which is a U-shaped structure with an opening facing downwards. A fixing block is fixedly installed inside the upper clamping block. The upper clamping block has a threaded hole that mates with a stud. One end of the stud is rotatably connected to a movable block. The movable block and the fixing block are positioned opposite each other, and the upper surface of the movable block slides against the upper clamping block. A pin is fixedly installed at the other end of the stud.

[0018] Preferably, the rotation limiting structure includes a limiting block, the connecting seat is provided with a limiting groove that allows the limiting block to rotate, one end of the limiting block is located in the limiting groove and is rotatably connected to the connecting seat through a pin, the limiting block is provided with a through hole, the connecting seat is provided with a locking hole, the locking hole includes a 90° locking hole and a 180° locking hole, and the through hole of the limiting block and the locking hole of the connecting seat are connected by a locking pin.

[0019] Preferably, the sliding structure includes two slide rails, which are fixedly connected to the slide base. Slider blocks are fixedly installed on both sides of the base plate. The sliders slide in cooperation with the slide rails. The outer side of the slider is provided with a socket hole, and the slide rail is provided with a blind hole. The slider and the slide rail are connected by a pin.

[0020] Preferably, the end clamping structure includes a clamping frame fixedly installed at the end of the slide, the clamping frame having an installation end facing the slide, a pressure plate being provided between the installation end and the slide, two guide posts being fixedly installed upward on the pressure plate, the installation end having guide holes that slide with the guide posts, and a hand-tightening bolt for pressing the pressure plate being installed on the installation end.

[0030] like Figure 1-8 As shown, an angle adjustment device for a peel force testing machine includes an upper clamping part and a lower clamping part.

[0031] The upper clamping part includes a top plate 1, a top frame 2 is fixedly installed on one side of the top plate, a moving block 3 is installed on the top plate through a moving structure, a connecting rod 4 is fixedly installed at the lower end of the moving block, and an upper clamping structure is installed downward on the connecting rod.

[0032] The lower clamping part includes a connecting seat 5 fixedly installed on the base 200 of the testing machine. The connecting seat is connected to the base plate 6 through a rotation limiting structure. The base plate is connected to the slide 7 through a sliding structure. One end of the slide is equipped with an end clamping structure. The other end of the slide is fixedly connected to one end of the rope 8. The other end of the rope is fixed with a threaded head 9. The top plate is provided with a threaded hole 10 that mates with the threaded head. One end of the slide is rotatably equipped with a guide wheel 11 for guiding the rope.

[0033] In this way, the upper and lower clamping parts are used to clamp the material. The angle of the lower clamping part can be switched between 90° and 180° test angles. There is no need to disassemble the lower clamping part, making the operation convenient, time-saving and labor-saving.

[0034] Specifically, the upper clamping part is connected to the device inside the machine body 100 of the testing machine through the top frame. The device inside the machine body drives the upper clamping part to move in the vertical direction, thereby moving the material and realizing peeling.

[0035] When a 90° peel test is required, the rotation limiting structure restricts the base plate to a horizontal position. At this time, the slide is also set horizontally, the threaded head connects to the threaded hole of the top plate, and the guide wheel guides the rope, adhering one end of the material to the...

[0036] On the substrate, the end clamping structure is used to clamp and fix the substrate, and the upper clamping structure is used to fix the other end of the material. The position of the slide and the upper clamping part is adjusted so that the upper part of the material remains vertical and the rope is in a taut state. Then, the testing machine is started, and the device inside the machine body drives the upper clamping part to move upward. Through the setting of the top plate and the rope, the slide is moved synchronously, so that the upper part of the material always remains vertical during the peeling process, ensuring 90° peeling and improving the accuracy of the test results.

[0037] When a 180° peel test is required, rotate the base plate to a vertical position and rotate the limiting structure to lock the base plate. At this time, the slide is also in a vertical position, the threaded head disengages from the threaded hole of the top plate, and one end of the material is bonded to the substrate. The substrate is clamped and fixed using the end clamping structure, and the other end of the material is fixed using the upper clamping structure. The position of the moving block is adjusted by the moving structure so that the material is in a folded state and both sides of the material are in a vertical state. Then, the testing machine is started, and the device inside the machine body drives the upper clamping part to move upward, so that a 180° peel can be performed.

[0038] When switching between 90° peel test and 180° peel test, there is no need to disassemble the lower clamping part. The overall structure is simple and coordinated, making it easy to use.

[0039] In implementation: The movable structure includes upright plates 12 fixedly installed on both sides of the lower end of the top plate and screw rods 13 rotatably connected to the upright plates. One end of the screw rod is located on the outside of the upright plate and is fixedly installed with a knob 14. The movable block is fixedly installed with a nut that is threadedly engaged with the screw rod. The upper surface of the movable block is slidably attached to the top plate.

[0040] In this way, turning the knob drives the screw to rotate. Through the cooperation of the screw and nut, and the sliding contact between the upper surface of the moving block and the top plate, the moving block is moved. The position of the moving block can be manually adjusted, making the operation simple. When switching from a 90° peel test to a 180° peel test, the slide needs to rotate 90 degrees. At this time, in order to keep the material in a folded state and the two sides of the material in a vertical state, the moving block needs to be moved to adjust the orientation of the material.

[0041] In implementation: The upper clamping structure includes an upper clamping block 15, which is a U-shaped structure with the opening facing downwards. A fixing block 16 is fixedly installed inside the upper clamping block. The upper clamping block is provided with a threaded hole that mates with a stud 17. One end of the stud is rotatably connected to a movable block 18. The movable block and the fixing block are positioned opposite each other, and the upper surface of the movable block slides against the upper clamping block. A pin 19 is fixedly installed at the other end of the stud.

[0042] In this way, when clamping the material, rotating the pin drives the stud to rotate. The stud rotates and engages with the movable block, and also engages with the threaded hole of the upper clamping block. As the stud rotates, it pushes the movable block towards the fixed block, thus clamping the material. It is manually operated for ease of use.

[0043] In implementation: The rotation limiting structure includes a limiting block 20, and the connecting seat is provided with a limiting groove 21 that allows the limiting block to rotate. One end of the limiting block is located in the limiting groove and is rotatably connected to the connecting seat through a pin 22. The limiting block is provided with a through hole 23, and the connecting seat is provided with a locking hole. The locking hole includes a 90° locking hole 24 and a 180° locking hole 25. The through hole of the limiting block and the locking hole of the connecting seat are connected by a locking pin 26.

[0044] Thus, the limiting groove has two side surfaces, a bottom surface, and an end surface. The end of the limiting block is semi-circular and rotatably connected to the connecting seat via a pin. During a 90° peel test, the slide is horizontal, and one side of the limiting block is in contact with the end surface. During a 180° peel test, the slide is vertical, and one side of the limiting block is in contact with the bottom surface. The connecting seat has 90° and 180° locking holes. During a 90° peel test, the locking pin is inserted into the 90° locking hole and through hole; during a 180° peel test, the locking pin is inserted into the 180° locking hole and through hole, achieving position locking.

[0045] In implementation: The sliding structure includes two slide rails 27, which are fixedly connected to the slide base. Slider blocks 28 are fixedly installed on both sides of the base plate. The sliders slide in cooperation with the slide rails. The outer side of the slider is provided with a socket 29. The slide rail is provided with a blind hole 30. The slider and the slide rail are connected by a pin 31.

[0046] In this way, through the cooperation of the slide rail and the slider, the slide can move horizontally as the top plate rises during the 90° peel test, making the peel angle more accurate and improving the reliability of the test results. When performing the 180° peel test, the slide needs to be fixed. The pin is inserted into the insertion hole and the blind hole to fix the position of the slider. The slider is fixedly mounted on the base plate, and the angle of the base plate is fixed by the rotation limiting structure, thus fixing the position of the slide. At this time, the 180° peel test can be performed.

[0047] In implementation: The end clamping structure includes a clamping frame 32 fixedly installed at the end of the slide. The clamping frame has an installation end facing the slide. A pressure plate 33 is provided between the installation end and the slide. Two guide posts 34 are fixedly installed upward on the pressure plate. The installation end is provided with guide holes that slide with the guide posts. The installation end is also equipped with a hand-tightening bolt 35 for pressing the pressure plate.

[0048] In this way, when pressing the substrate, one end of the substrate is placed between the pressure plate and the slide, and the hand-tightening bolt is turned. The hand-tightening bolt applies force to the pressure plate, so that the pressure plate presses the substrate under the guidance of the guide post. The operation is simple.

[0049] In summary, the functions of the upper and lower clamping sections are achieved through manual adjustment. The internal mechanisms that move the upper clamping section and perform force detection are all part of the existing testing machine structure and are not within the scope of this application. This application allows for switching between 90° and 180° peel tests without disassembling the lower clamping section, thus improving overall performance.

[0050] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications made to the present utility model by those skilled in the art without departing from the spirit of the present utility model shall fall within the protection scope of the present utility model.
