Description

Technical Field

[0001] This utility model relates to the field of release film peel testing technology, specifically a release film peel force testing device. Background Technology

[0002] A release film peel force tester is a device used to measure the peel force between a release film and a substrate. It is primarily used to evaluate the peel performance of film materials, especially in industries involving adhesives, coatings, and films. This test determines whether the release film can peel off smoothly and evenly in practical applications, without damage or residue. This test is crucial for ensuring the quality of film materials in applications such as packaging, pasting, labeling, and protective films.

[0003] Currently, existing release film peel force testing devices require placing the film plate on the operating table for the film peel test. After the test is completed, the peeled plate is removed and a new film plate is replaced for the peel force test. Although this method can achieve the peel force test, it is cumbersome to operate and has low testing efficiency because it requires waiting for the previous film plate to be completed before the new material can be loaded. Utility Model Content

[0004] Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a release film peel force testing device, which has the advantages of improving feeding efficiency and reducing operational complexity, thus solving the problems of cumbersome operation and low testing efficiency caused by the current single feeding method.

[0006] Technical solution

[0007] To achieve the above objectives, the present invention provides the following technical solution: a release film peel force testing device, comprising a moving plate, an outer slide rail, an inner slide rail, a drive assembly, and a peeler. The moving plate has two placement slots for placing film plates, but the two placement slots cannot place film plates at the same time. When the film is being peeled off, the other placement slot can be used to place the film plate.

[0008] Both sides of the movable plate are fixed with outer slide rails, and an inner slide rail is slidably sleeved inside the outer slide rails. A drive component for controlling the forward and backward movement of the movable plate is fixed at one end of the inner slide rail. When the drive component operates, it controls the forward and backward movement of the movable plate. During the movement, the outer slide rail slides on the side of the inner slide rail, which improves the stability of the forward and backward movement of the movable plate.

[0009] The movable plate is movably connected to a peeler for peeling off the membrane. When the movable plate moves telescopically, the two placement slots are aligned with the bottom of the peeler in sequence. When aligned, the membrane on the membrane plate is peeled off.

[0010] This release film peel force testing device tests the film tearing force by placing the film plate in the placement groove and clamping it with spring clamps. The drive assembly is then controlled to move the moving plate forward until one placement groove aligns with the bottom of the peeler, tearing the film off the plate. Simultaneously, the other placement groove opens, allowing the unprocessed film plate to be placed in it. The drive assembly is then controlled to move the moving plate backward, allowing the unprocessed film plate to pass through the bottom of the peeler for tearing force testing. At the same time, the peeled film plate is exposed, which can be removed before placing the unprocessed film plate.

[0011] As a further improvement to the above solution, a first fitting slot is provided in the placement slot, and a spring clamp is movably connected in the first fitting slot.

[0012] Through the above technical solution, the spring clamp is composed of a clamp and a spring. The spring pushes the clamp, so that the clamp fits against the side of the template placed in the placement groove, thereby improving the stability of the template placement.

[0013] As a further improvement to the above solution, a connecting button is fixed to one end of the movable plate, a linkage plate is fixed to the side of the connecting button, a retaining button is fixed to one end of the linkage plate, and a moving rod is fixed to one end of the retaining button.

[0014] Through the above technical solution, when the moving rod moves back and forth, the moving plate moves synchronously through the connecting plate.

[0015] As a further improvement to the above solution, the drive assembly includes a stabilizing plate vertically fixed to one end of the inner slide rail, with a stabilizing hole provided on the stabilizing plate, and the moving rod movably sleeved in the stabilizing hole.

[0016] The above technical solution allows the moving rod to move back and forth within the stabilizing hole, improving the stability of the moving rod's movement.

[0017] As a further improvement to the above solution, a connecting plate is vertically fixed to the side of the stabilizing plate, and a micro motor is fixed on the connecting plate. The output end of the micro motor passes through one side of the connecting plate, and a drive gear is fixed on the output end.

[0018] Through the above technical solution, the output end of the micro motor has the function of bidirectional rotation. When the micro motor is in operation, the output end drives the drive gear to rotate.

[0019] As a further improvement to the above solution, a transmission groove is provided on the side of the moving rod, and a tooth profile is provided on one side of the transmission groove, and the driving gear meshes with the tooth profile.

[0020] With the above technical solution, when the drive gear rotates, the force of meshing with the tooth profile causes the moving rod to move back and forth.

[0021] As a further improvement to the above solution, the peeler includes a support plate movably connected to the movable plate, and a stabilizing side plate is provided opposite to the side of the support plate, the stabilizing side plate being slidably connected to the side of the outer slide rail.

[0022] Through the above technical solution, stabilizing side plates are provided on both sides of the support plate, and the bottom of the stabilizing side plates is fixed to the ground or workbench, thereby improving the stability of the device during operation.

[0023] As a further improvement to the above solution, the bottom of the support plate has two connecting grooves opposite each other, a rotating roller is rotatably connected in the connecting grooves, a second mounting groove is opened in the rotating roller, a peeling rack is installed in the second mounting groove, and a tension detector is fixed in the second mounting groove, with the output end of the tension detector fixed on the peeling rack.

[0024] With the above technical solution, the rotating rollers are rotatably connected in the corresponding connecting grooves, and the peeling teeth of the two rotating rollers cannot be exposed at the same time. The peeling teeth on the rotating rollers are used to peel the film in the corresponding end of the groove.

[0025] As a further improvement to the above solution, both ends of the rotating roller are fixed with connecting rods. The connecting rods pass through the side of the support plate, and a rotating gear is fixed at one end of the connecting rod. At the same time, a rack is provided on the outer slide rail, and the rotating gear meshes with the rack. Meanwhile, a sleeve is fixed on the stabilizing side plate, and the rotating gear is rotatably connected inside the sleeve.

[0026] With the above technical solution, when the rotating gear rotates, it drives the rotating roller to rotate through the linkage rod, realizing the switching of the exposure and retraction of the peeling rack. When it is exposed, the film on the corresponding end film plate can be torn off, while when it is retracted, no film is torn off any film plate.

[0027] As a further improvement to the above solution, a sleeve is fixed to the side of the stabilizing side plate, and the sleeve is movably sleeved on the side of the moving rod.

[0028] With the above technical solution, when the moving rod moves back and forth, it slides back and forth inside the sleeve, and at the same time, the diameter of the moving rod matches the diameter inside the sleeve, thus improving the stability of the moving rod's movement.

[0029] Compared with the prior art, the present invention provides a release film peel force testing device, which has the following beneficial effects:

[0030] 1. This release film peel force testing device has two placement slots on a moving plate. The moving plate is controlled to move back and forth by a drive component so that the two placement slots correspond to the bottom of the peeler in sequence. When one placement slot corresponds to the peeler, the other placement slot can be loaded. After the release film peel force test of the previous film plate is completed, the test of the second film plate can be carried out quickly, thereby reducing the cumbersomeness of operation and improving the efficiency of testing.

[0031] 2. This release film peel force testing device has rotating rollers installed at both the front and rear ends of the bottom of the peeler to perform release film peel tests on the corresponding placement slots of the film plates. When the moving plate moves, the peeling teeth on the corresponding end of the rotating roller are exposed due to the meshing force of the rotating gear and the rack, while the peeling teeth on the other end of the rotating roller are retracted. Thus, when contacting the corresponding film plate, the film can be fully torn off. During the process, the force generated by tearing the film is detected by a tensile force detector, which effectively improves the practicality and flexibility of the device.

[0044] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0045] Example 1

[0046] Please see Figures 1-6 As shown, the release film peel force testing device proposed in this embodiment includes a moving plate 1, an outer slide rail 2, an inner slide rail 3, a drive assembly 4, and a peeler 5. The moving plate 1 has two placement slots 101 for placing film plates. However, the two placement slots 101 cannot place film plates at the same time. When one placement slot 101 is performing film peeling, the other placement slot 101 can place film plates.

[0047] Both sides of the movable plate 1 are fixed with outer slide rails 2, and an inner slide rail 3 is slidably sleeved inside the outer slide rails 2. A drive component 4 for controlling the forward and backward movement of the movable plate 1 is fixed at one end of the inner slide rail 3. When the drive component 4 is in operation, it controls the forward and backward movement of the movable plate 1. During the movement, the outer slide rail 2 slides on the side of the inner slide rail 3, which improves the stability of the forward and backward movement of the movable plate 1.

[0048] A peeler 5 for peeling the membrane is movably connected to the movable plate 1. When the movable plate 1 moves telescopically, the two placement slots 101 are aligned with the bottom of the peeler 5 in sequence. When aligned, the membrane on the membrane plate is peeled off.

[0049] The working principle of the release film peel force testing device proposed in this embodiment is as follows: In use, the film plate is placed in the placement groove 101 and clamped and fixed by the spring clamp 103. By controlling the operation of the drive component 4, the moving plate 1 moves forward. When one of the placement grooves 101 is aligned with the bottom of the peeler 5, the film on the film plate is torn off. At the same time, the other placement groove 101 is exposed. The unprocessed film plate is placed in the exposed placement groove 101. Then, the drive component 4 is controlled to move the moving plate 1 backward, so that the unprocessed film plate enters and exits the bottom of the peeler 5 for film tearing force testing. At the same time, the film plate that has been torn off is exposed. After removing the plate, the unprocessed film plate can be placed.

[0050] Example 2

A connecting plate 403 is vertically fixed to the side of the stabilizing plate 401. A micro motor 404 is fixed on the connecting plate 403. The output end of the micro motor 404 passes through one side of the connecting plate 403, and a drive gear 405 is fixed on the output end. A transmission groove 108 is provided on the side of the moving rod 107. A tooth profile 109 is provided on one side of the transmission groove 108. The drive gear 405 meshes with the tooth profile 109.

[0052] In this design, the spring clamp 103 consists of a clamp and a spring. The spring pushes the clamp, causing it to fit against the side of the template placed in the placement slot 101, thus improving the stability of the template placement. When the moving rod 107 moves back and forth, it drives the moving plate 1 to move synchronously through the connecting plate 105. The moving rod 107 moves back and forth within the stabilizing hole 402, improving the stability of the moving rod 107. The output end of the micro motor 404 has a bidirectional rotation function. When the micro motor 404 is operating, the output end drives the drive gear 405 to rotate. When the drive gear 405 rotates, the force of meshing with the tooth profile 109 causes the moving rod 107 to move back and forth.
