Description

Technical Field

[0001] The invention relates to the technical field of peeling force testing of organic silicone pressure-sensitive adhesives, and in particular to a peeling force testing device for organic silicone pressure-sensitive adhesives. Background Art

[0002] Silicone pressure-sensitive adhesives generally refer to pressure-sensitive adhesives based on silicone polymers, or acrylic and silicone-modified rubber pressure-sensitive adhesives modified with silicone polymers. Compared with traditional acrylic and rubber pressure-sensitive adhesives, silicone pressure-sensitive adhesives offer superior resistance to chemicals, water, oil, solvents, high and low temperatures, thermal degradation, and oxidative degradation. Furthermore, they can bond to a variety of difficult-to-bond materials, such as untreated polyolefins (BOPP, PET, PE, etc.), fluoroplastics, polyimides, and polycarbonates.

[0003] During the production process, silicone pressure-sensitive adhesives require peel strength testing. This typically involves squeezing the adhesive onto a flat surface, such as a pick, then covering it with other paper materials to create a sample, which is then placed on the test equipment. This separates sample production from testing, and requires multiple fixation and movement of the sample, increasing complexity and reducing work efficiency. Summary of the Invention

[0004] The present invention discloses a device for testing the peeling force of an organic silicone pressure-sensitive adhesive, which aims to solve the technical problems that during the testing process, sample preparation and testing need to be separated, and the sample needs to be fixed and moved multiple times, which increases the complexity and reduces the work efficiency.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] 7. The swiftly and minutely adjusting device for a wood-planer working table as claimed in claim 1, wherein said linking rod and said adjusting base are pivotally connected to each other with a bolt, and said bolt has a round shank to contact with said linking rod. said linking rod is pivotally connected to said linking rod. said linking rod is pivotally connected to said linking rod.

[0007] The device is provided with a driving mechanism, a pressing roller, an electric clamp and a peeling force sensing slide, wherein the glass slide is fixed by a limiting mechanism. At this time, under the action of the driving mechanism, the glass slide is placed horizontally, and the sample can be directly made. After squeezing out the glue, the paper material is covered on the glue and then moved on the slide rail to reinforce the connection by pressing the roller. One end of the paper material needs to be placed on the comparison rod. When the air-drying time set by the timer is reached, the servo motor is automatically controlled to work and drive the worm to rotate. Under the self-locking function, while ensuring the support stability, the direction of the glass slide can also be turned to a vertical state. After the comparison rod is limited, the electric clamp automatically clamps one end of the paper, and then the peeling force sensing slide drives it to be peeled and the peeling force test. Under this structure, sample preparation and testing can be completed at the same position. At the same time, the air-drying and testing steps after sample preparation can be completed automatically, which is conducive to improving work efficiency and reducing work difficulty.

[0008] The lockhole that is formed on the two ends of the support frame is formed on the upper surface of the support frame, and the lockhole that is formed on the two ends of the support frame is formed.

[0009] By setting a limiting mechanism, when installing a glass slide, the bottom plate is bent and the glass slide is inserted so that the two slots therein are engaged with the second card block. After the bottom plate is folded back, it is flush with the mounting frame. The square block is rotated by the knob so that it passes through the square hole. Under the action of the spring, the first card block is engaged with the other two slots to fix the glass slide. Under this structure, the glass slide can be limited quickly and the active surface of the glass slide can be fully exposed, which further facilitates the use of the pressing roller when preparing samples.

[0010] In a preferred embodiment, the shielding mechanism includes a film, and Velcro surfaces are respectively provided on both sides of the bottom end of the film, and Velcro adhesive surfaces are respectively provided on the outer walls of the same side of the support plate and the side support plate, and the Velcro adhesive surfaces are connected to the Velcro adhesive surfaces. The outer walls of the opposite sides of the support plate and the side support plate are respectively provided with multiple connecting rods, and the multiple connecting rods are distributed with equal density. The outer walls of the opposite sides of the two groups of connecting rods are respectively fixedly connected with hinge grooves, and a hinge rod is movably hinged in each hinge groove, and the outer walls of the opposite sides of the two hinge rods are respectively fixedly connected with guide plates, and the opposite ends of the two guide plates are hinged to each other.

[0011] By providing a shielding mechanism, in the limiting mechanism, although the surface of the glass slide is completely exposed and higher than the support plate and the side support plate after being fixed, if the glue is squeezed too much, the glue may overflow during the pressing process and fall to one side of the limiting mechanism. The shielding mechanism can collect and block the fallen glue, thereby protecting the limiting mechanism under the film. Under the action of the guide plate, when the support plate and the side support plate are merged, the two guide plates are bent upward under the action of the hinge groove to lift the film, thereby preventing the film from being collected downward and affecting the normal use of the limiting mechanism.

[0012] 7. The swiftly and minutely adjusting device for a wood-planer working table as claimed in claim 1, wherein said linking rod and said adjusting base are pivotally connected to each other with a bolt, and said bolt has a round shank to contact with said linking rod. said linking rod is pivotally connected to said linking rod. said linking rod is pivotally connected to said linking rod. The organic silicon pressure-sensitive adhesive peeling force testing device provided by the present invention has the technical effect of being able to complete sample preparation and test steps at the same location, avoiding turnover, being conducive to improving work efficiency and reducing work difficulty.

At the same time, the square hole 309 and the square block 307 have the same specifications. The support rod 306 is located at the center of the two springs 305. When the glass slide 5 is installed, the bottom plate 311 is bent and the glass slide 5 is inserted so that the two card slots 301 therein are engaged with the second card block 313. At this time, the glass slide 5 is completely covered on the outer wall of the mounting frame 312, and the square block 307 is horizontal.

Under the action of the guide plate 404, when the support plate 304 and the side support plate 310 are merged, under the action of the hinge groove 405, the two guide plates 404 are bent upward to lift the film 401, thereby preventing the film 401 from being collected downward and affecting the normal use of the limiting mechanism 3.

[0030] Working principle: During the working process, the glass slide 5 is fixed by the limiting mechanism 3. At this time, under the action of the driving mechanism 9, the glass slide 5 is placed horizontally, and the sample can be made directly. After squeezing out the glue, the paper material is covered on the glue and then moved on the slide rail 10 by pressing the roller 11 to reinforce the connection. One end of the paper material needs to be placed on the comparison rod 6. After the air-drying time set by the timer 901 is reached, the servo motor 902 is automatically controlled to work, driving the worm 904 to rotate. Under the self-locking function, while ensuring the support stability, the direction of the glass slide 5 can also be turned to present a vertical state. Compared with the limit of the contrast rod 6, the electric clamp 7 automatically clamps one end of the paper, and then the peeling force sensing slide 1 drives it to peel and test the peeling force. Under this structure, sample preparation and testing can be completed at the same position. At the same time, the air drying and testing steps after sample preparation can be completed automatically, which is conducive to improving work efficiency and reducing work difficulty. When installing the glass slide 5, the bottom plate 311 is bent and the glass slide 5 is inserted so that the two card slots 301 are engaged with the second card block 313. At this time, the glass slide 5 is completely covered on the outer wall of the mounting frame 312, the square block 307 is horizontal outside the square hole 309, and the spring 305 The bottom plate 311 is folded back to make it flush with the mounting bracket 312, and the square block 307 is rotated by the knob 308 to pass through the square hole 309. Then, under the action of the spring 305, the first clamping block 302 is clamped into the other two clamping slots 301 to fix the glass slide 5. Under this structure, the glass slide 5 can be quickly limited, and the active surface of the glass slide 5 can be fully exposed, which further facilitates the use of the pressing roller 11 when preparing the sample. In the limiting mechanism 3, although the surface of the glass slide 5 is completely exposed and higher than the support plate 304 and the side support plate 310 after being fixed, if the glue is squeezed out, the glass slide 5 will be locked. If too much pressure is applied, the glue may overflow during the pressing process and fall to one side of the limiting mechanism 3. In the shielding mechanism 4, the film 401 connected by Velcro is spread flat on the top after the support plate 304 and the side support plate 310 are opened, which can collect and block the fallen glue and protect the limiting mechanism 3 under the film 401. Under the action of the guide plate 404, when the support plate 304 and the side support plate 310 are merged, under the action of the hinge groove 405, the two guide plates 404 bend upward to lift the film 401, thereby preventing the film 401 from collecting downward and affecting the normal use of the limiting mechanism 3.
