Description

Technical Field

[0001] This utility model relates to the field of double-sided adhesive performance testing technology, specifically to a high-efficiency flame-retardant double-sided adhesive performance testing device. Background Technology

[0002] The double-sided adhesive performance testing device measures the adhesion and durability of double-sided adhesive during use, helping manufacturers evaluate the quality and performance of double-sided adhesive to ensure its reliability and durability in actual use. In testing high-efficiency flame-retardant double-sided adhesive, the device adheres the adhesive to a test plate, suspends a standard load at the bottom, and after a period of time, measures the distance the adhesive slides down or the adhesion time, using these measurements to assess the durability of the adhesive bond.

[0003] According to existing technical field publication CN220490652U, a high-efficiency flame-retardant double-sided adhesive performance testing device is disclosed. In the process of testing the adhesion persistence of double-sided adhesive, if the double-sided adhesive falls with a weight, the lower end of the testing device has an open box. The weight falls into the inner side of the open box, and the sponge pad can provide a certain degree of protection for the weight, preventing damage. The sponge pad also provides partial cushioning. Simultaneously, the sponge pad, through a partition, transfers most of the falling force of the weight to the telescopic spring, thus reducing the impact of the falling weight on the overall testing device. However, this double-sided adhesive performance testing device only tests the adhesion persistence of one side of the double-sided adhesive, not the other side. This results in an incomplete overall adhesion persistence test result, potentially leading to errors in the performance evaluation of the double-sided adhesive. Therefore, to address the above problems, we propose a high-efficiency flame-retardant double-sided adhesive performance testing device. Utility Model Content

[0004] The purpose of this invention is to provide a high-efficiency flame-retardant double-sided adhesive performance testing device to solve the problem that the current double-sided adhesive performance testing device only tests the adhesion durability of one side of the double-sided adhesive and does not test the adhesion durability of the other side, resulting in incomplete overall adhesion durability test results and potential errors in the performance evaluation of the double-sided adhesive.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A high-efficiency flame-retardant double-sided adhesive performance testing device includes a housing and a connecting plate. The connecting plate is fixedly connected to the inner side of the housing. A connecting block is fixedly connected to the lower end of the connecting plate. A test plate is fixedly connected to the lower end of the connecting block. Double-sided adhesive is pasted on the front end of the test plate. A plastic bottom film is provided at the front end of the double-sided adhesive. An easy-tear sticker is fixedly connected to the upper end of the plastic bottom film. A shaping strip is fixedly connected to the front end of the plastic bottom film. A fixing plate is fixedly connected to the lower end of the double-sided adhesive. A circular hole is opened on the inner side of the fixing plate. A weight is suspended inside the circular hole. A limit frame is fixedly connected to the upper end of the weight. Limit blocks are fixedly connected to the left and right ends of the weight. A limit plate is fixedly connected to the inner wall of the bottom end of the housing. A guide groove is opened on the side of the limit plate near the weight. A buffer spring is fixedly connected to the inner wall of the bottom end of the housing. A support plate is fixedly connected to the upper end of the buffer spring. A sponge pad is fixedly connected to the upper end of the support plate.

[0007] Preferably, the box is hollow inside, the number of connecting blocks is three, and the number of test plates is three.

[0008] Preferably, the plastic base film is located at the front end of the fixing plate, the easy-tear sticker is located at the front end of the test plate, and the shaping strip is rectangular in shape.

[0009] Preferably, the fixing plate is located directly above the limiting frame, the limiting frame is U-shaped, and the outer side of the limiting block is slidably connected with a guide groove.

[0010] Preferably, the limiting plate is located on the left and right sides of the weight, and the number of buffer springs is several. The limiting plate is located on the left and right sides of the support plate and the sponge pad.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] In this invention, by setting up a plastic base film, a shaping strip, a fixing plate, and a limiting frame, the double-sided adhesive detaches from the test plate. After the weights slide off, the lower end of the fixing plate slides into the limiting frame. The limiting frame supports the double-sided adhesive as a whole through the fixing plate, reducing the double-sided adhesive from tilting, deforming, and adhering to the weights. After testing one side of the double-sided adhesive, the double-sided adhesive and fixing plate are removed from the weights, the plastic base film is peeled off, and the other side of the double-sided adhesive is then pasted onto the test plate for testing. This device can test both sides of the double-sided adhesive, making the test results more complete and reducing subsequent evaluation errors. Attached Figure Description

[0020] Please see Figure 1-5 This utility model provides a technical solution:

[0021] A high-efficiency flame-retardant double-sided adhesive performance testing device includes a housing 1 and a connecting plate 2. The connecting plate 2 is fixedly connected to the inner side of the housing 1. A connecting block 3 is fixedly connected to the lower end of the connecting plate 2. A test plate 4 is fixedly connected to the lower end of the connecting block 3. Double-sided adhesive 5 is pasted on the front end of the test plate 4. A plastic bottom film 6 is provided at the front end of the double-sided adhesive 5. An easy-tear sticker 7 is fixedly connected to the upper end of the plastic bottom film 6. A shaping strip 8 is fixedly connected to the front end of the plastic bottom film 6. A fixing plate 9 is fixedly connected to the lower end of the double-sided adhesive 5. A circular hole 10 is provided on the inner side, and a weight 11 is suspended inside the circular hole 10. A limit frame 12 is fixedly connected to the upper end of the weight 11, and limit blocks 13 are fixedly connected to the left and right ends of the weight 11. A limit plate 14 is fixedly connected to the inner wall of the bottom end of the box body 1. A guide groove 15 is provided on the side of the limit plate 14 near the weight 11. A buffer spring 16 is fixedly connected to the inner wall of the bottom end of the box body 1. A support plate 17 is fixedly connected to the upper end of the buffer spring 16, and a sponge pad 18 is fixedly connected to the upper end of the support plate 17.

[0022] The interior of the chamber 1 is hollow. There are three connecting blocks 3 and three test plates 4. The plastic bottom film 6 is located at the front end of the fixing plate 9. The easy-tear adhesive 7 is located at the front end of the test plate 4. The shaping strip 8 is rectangular in shape to facilitate the setting of the shaping strip 8 and the plastic bottom film 6. The plastic bottom film 6 is a rigid bottom film, so that the double-sided adhesive 5 remains vertical and does not deform after sliding, reducing the impact on the other side of the test. The fixing plate 9 is located directly above the limiting frame 12. The limiting frame 12 is U-shaped. The outer side of the limiting block 13 is slidably connected to the guide groove 15. The limiting plate 14 is located on the left and right sides of the weight 11. There are several buffer springs 16. The limiting plate 14 is located between the support plate 17 and the sponge pad 18. On both sides, a connecting plate 2 is fixedly connected to the inner side of the box 1. A connecting block 3 is fixedly connected to the lower end of the connecting plate 2. A test plate 4 is fixedly connected to the lower end of the connecting block 3. Double-sided tape 5 is pasted to the front end of the test plate 4. A plastic bottom film 6 is provided at the front end of the double-sided tape 5 to protect the other side of the double-sided tape 5, thereby reducing dust in the air from adhering to the other side of the double-sided tape 5 and reducing the impact of dust on the test results of the other side. An easy-tear sticker 7 is fixedly connected to the upper end of the plastic bottom film 6 for easy removal of the plastic bottom film 6. A shaping strip 8 is fixedly connected to the front end of the plastic bottom film 6, and a fixing plate 9 is fixedly connected to the lower end of the double-sided tape 5 for easy installation of the shaping strip. 8. With the fixing plate 9 and limiting frame 12 in place, the double-sided adhesive 5 detaches from the test plate 4. After the weight 11 slides off, the lower end of the fixing plate 9 slides into the limiting frame 12. The limiting frame 12 supports the double-sided adhesive 5 as a whole through the fixing plate 9, reducing the deformation and adhesion of the double-sided adhesive 5 to the weight 11. After testing one side of the double-sided adhesive 5, the double-sided adhesive 5 and the fixing plate 9 are removed from the weight 11, and the plastic bottom film 6 is peeled off, so that the other side of the double-sided adhesive 5 is pasted onto the test plate 4 for testing the other side. This device can test both sides of the double-sided adhesive 5, making the test results more complete and reducing subsequent evaluation errors. The inner side of the fixing plate 9 is open. A circular hole 10 is provided, and a weight 11 is suspended inside the circular hole 10. A limit frame 12 is fixedly connected to the upper end of the weight 11, and limit blocks 13 are fixedly connected to the left and right ends of the weight 11. This facilitates the setting of the limit blocks 13, the limit plate 14, and the guide groove 15. The guide groove 15 guides and limits the weight 11 through the limit blocks 13, thereby preventing the weight 11 from falling to the ground and tipping over. A limit plate 14 is fixedly connected to the inner wall of the bottom end of the box 1. A guide groove 15 is opened on the side of the limit plate 14 near the weight 11. A buffer spring 16 is fixedly connected to the inner wall of the bottom end of the box 1. A support plate 17 is fixedly connected to the upper end of the buffer spring 16, and a sponge pad 18 is fixedly connected to the upper end of the support plate 17.

[0023] Workflow: When testing the adhesion durability of one side of the double-sided adhesive 5, one side of the double-sided adhesive 5 is attached to the test plate 4. Then, the weight 11 pulls the double-sided adhesive 5 downwards, causing it to detach from the test plate 4. The weight 11 then pulls the double-sided adhesive 5 downwards. The guide groove 15 guides and limits the weight 11 through the limiting block 13, thus preventing the weight 11 from tipping over upon landing. After the weight 11 slides down, its lower end adheres to the sponge pad 18, which protects the lower end of the weight 11. Simultaneously, the sponge pad 18 cushions the lower end of the weight 11 through the support plate 17 and the buffer spring 16. At this time, the fixing plate 9... The end slides into the limiting frame 12, which supports and limits the fixing plate 9 and the double-sided adhesive 5 as a whole. The shaping strip 8 and the plastic bottom film 6 keep the double-sided adhesive 5 vertical and undeformed after sliding. After testing one side of the double-sided adhesive 5, the double-sided adhesive 5 and the fixing plate 9 are removed from the weight 11. The easy-tear sticker 7 is pulled outward to peel off the plastic bottom film 6 and the shaping strip 8, so that the other side of the double-sided adhesive 5 is pasted on the test plate 4. The weight 11 is then suspended on the fixing plate 9 again to test the other side. This device can test both sides of the double-sided adhesive 5, making the test results of the double-sided adhesive 5 more complete and reducing the subsequent evaluation error of the double-sided adhesive 5.

[0024] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
