[0030] Specifically, three specimens 12 are stacked together, and the clamping plate 13 is pushed. The clamping plate 13 drives the connecting rod 24 to move, compressing the support spring 25. The clamping plate 13 is supported by the sliding connection between the connecting rod 24 and the fixed chamber 16, improving the stability of the clamping plate 13. Then, the stacked specimens 12 are placed between two clamping plates 13. The clamping plate 13 is released, and the clamping plate 13 is pushed back to its original position by the action of the support spring 25. The clamping plate 13 and the specimen 12 are attached to each other, fixing the specimen 12.

Through the contact between the linkage rod 15 and the linkage groove 30, the scraper 11 is moved, and the scraper 11 cleans the glue on the rollers 19.

[0034] Example 3: Please refer to Figures 1 to 5In this embodiment, based on Embodiment 1 and Embodiment 2, a drive assembly is provided on the base plate 1. The drive assembly includes a drive motor 2, which is fixedly installed on the top surface of the base plate 1.

[0035] The drive rod 23 is rotatably connected to the fixed frame 8 via a bearing. The connecting chamber 6 is a cuboid with a hollow interior and a missing top surface. The air outlet slot 10 is covered by the exhaust fan 14.

[0036] It should be noted that the heating element 9 and the exhaust fan 14 are conventional devices known to the public in the prior art, and their specific structures and working principles will not be described in detail in this article.

[0037] Specifically, the drive motor 2 is started, and the output end of the drive motor 2 drives the drive rod 23 to rotate, which in turn drives the drive gear 3 to rotate. Through the meshing between the drive gear 3, the first driven gear 4, and the second driven gear 22, the test piece 12 and the roller 19 are rotated. The heating tube 9 and the exhaust fan 14 are started. The exhaust fan 14 draws external air through the filter screen 7 into the interior of the connecting chamber 6. The air is filtered by the filter screen 7 and heated by the heating tube 9. The heated air is discharged from the connecting chamber 6 through the air outlet slot 10, and the test piece 12 is quickly dried after the glue is applied.

[0038] The working principle of the above embodiments is as follows:

[0039] Three specimens 12 are stacked together. The clamping plate 13 is pushed, causing the connecting rod 24 to move and compress the support spring 25. The sliding connection between the connecting rod 24 and the fixed chamber 16 supports the clamping plate 13, improving its stability. The stacked specimens 12 are then placed between two clamping plates 13. The clamping plate 13 is released, and the support spring 25 pushes it back to its original position, fixing it in place. Sealant is poured into the collection tray 20. The pressure plate 29 is grasped, and the first screw 5 and the second screw 18 are rotated. The threaded connection between the first screw 5 and the fixing frame 8 moves the pressure plate 29 downwards, fixing the fixed chamber 16. The threaded connection between the second screw 18 and the fixing frame 8, and the sliding connection between the sliding block 21 and the sliding groove 17, causes the second screw 18 to move the front roller 19. The specimen 12 is attached to the two rollers 19. The drive motor 2 is started, and the output end of the drive motor 2 drives the drive rod 23 to rotate, which in turn drives the drive gear 3 to rotate. Through the meshing between the drive gear 3, the first driven gear 4, and the second driven gear 22, the specimen 12 and the rollers 19 are rotated. The surface of the rollers 19 is coated with sealant, and the specimen 12 is coated. After the specimen 12 is coated, the scraper 11 is pulled. Through the attachment between the linkage rod 15 and the linkage groove 30, the scraper 11 is moved. The scraper 11 cleans the sealant on the rollers 19. The heating tube 9 and the exhaust fan 14 are started. The exhaust fan 14 draws external air through the filter screen 7 into the interior of the connecting chamber 6. The air is filtered by the filter screen 7 and heated by the heating tube 9. The heated air is discharged from the connecting chamber 6 through the air outlet slot 10, and the coated specimen 12 is quickly dried.
