[0002] The adhesive application process mainly uses a sheet adhesive application machine to apply sheet adhesive, and during the application process, a pressure roller is usually used to press the adhesive to ensure a firm bond.

[0003] In existing sheet adhesive applicators, after the adhesive is applied to the workpiece, it is compacted by a pressure roller. However, after the pressure roller has completed the compaction process, air bubbles will still remain inside the adhesive, making it impossible to effectively expel the air. The pressure roller is fixedly connected to the motor, making it difficult to replace it as needed. Therefore, we provide an anti-air bubble pressure roller assembly for sheet adhesive applicators. Utility Model Content

[0004] The purpose of this utility model is to provide an anti-bubble pressure roller assembly for a sheet adhesive applicator. Through grooves and adjusting rods, it solves the problem that in the existing sheet adhesive applicator, after the workpiece is coated with adhesive and compacted by the pressure roller, air bubbles still remain inside the adhesive after the pressure roller has completed the compaction process, and the air cannot be effectively discharged. Furthermore, the pressure roller is fixedly connected to the motor, making it difficult to replace it as needed.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] An anti-bubble pressure roller assembly for a sheet adhesive applicator includes a crossbeam, a hydraulic column is provided on the top of the crossbeam, a lifting frame is fixedly connected to the top of the hydraulic column, a motor is provided on the surface of the lifting frame, and a pressure roller is provided on the side of the motor.

[0007] The surface of the pressure roller has a groove, the inside of the lifting frame has a through groove, the inside of the through groove has a movable seat, the inside of the movable seat has an adjusting rod, the surface of the movable seat is fixedly connected to a connecting block, one end of the pressure roller has a connecting groove, the other end of the pressure roller has a transmission groove, and the side end of the motor is fixedly connected to a transmission block.

[0008] Preferably, both the connecting block and the connecting groove are cylindrical, and both the transmission block and the transmission groove are square columnar.

[0009] By adopting the above technical solution, the plug-in structure between the connecting block and the connecting groove and between the transmission block and the transmission groove enables the disassembly and replacement of the pressure roller body.

[0010] Preferably, a limiting block is fixedly sleeved on the surface of the adjusting rod inside the lifting frame, and the limiting block has a circular ring structure.

[0011] By adopting the above technical solution, the limiting block can limit the adjustment rod, allowing the adjustment rod to rotate within a limited range, thus enabling the moving seat to perform stable adjustment.

[0012] Preferably, the top of the movable seat and the through groove are both cross-shaped structures, and the surface of the movable seat is in close contact with the inner wall of the through groove.

[0013] By adopting the above technical solution, the cross-shaped structure can make the connection between the moving base and the lifting frame more compact and stable, thereby improving the structural stability of the device.

[0014] Preferably, a support is fixedly connected to the bottom of the crossbeam, a groove is provided inside the support, a slider is embedded inside the groove, an electric telescopic rod is fixedly connected to the bottom of the slider, and a scraper is provided on the side end of the electric telescopic rod.

[0015] By adopting the above technical solution, the electric telescopic rod can control the slider to enter the groove on the surface of the pressure roller to clean the internal residual glue and dirt, making the cleaning of the device more labor-saving and convenient.

[0016] Preferably, both the slider and the groove are T-shaped, and the side end of the scraper is wedged into the groove.

[0017] By adopting the above technical solution, the T-shaped structure can limit the movement of the slider inside the groove, and also directionalize the electric telescopic rod to ensure stable movement of the scraper, thus improving the transmission effect of the device.

[0019] By adopting the above technical solution, the scraper block can be disassembled and replaced according to the pressure roller body, thus improving the applicability of the device.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0021] This invention utilizes a groove design. Air bubbles in the sheet adhesive are squeezed into the groove by the pressure roller and gradually moved along the spiral groove before being discharged. The transmission groove on the side end of the required model pressure roller is fitted onto the transmission block. The rotating adjustment rod limit block acts as a limit. Under the meshing connection between the adjustment rod and the moving seat, the moving seat moves within the through groove, causing the connecting block to be inserted into the connecting groove. The motor can then drive the pressure roller to rotate. The pressure roller can gradually remove air bubbles from the sheet adhesive through the groove. Alternatively, a pressure roller body with a suitable groove can be selected for installation and use according to actual needs. The device has high applicability and better anti-bubble effect.

[0022] This invention features a scraper block. An electric telescopic rod controls the end of the scraper block to enter the groove. Then, a motor is started to control the rotation of the pressure roller body. Under the limiting sliding connection between the slider and the internal groove of the support, the scraper block is driven by the groove on the surface of the pressure roller body to move horizontally, thereby removing all residual adhesive and dirt in the groove 23. This makes it easy to clean the residual adhesive and dirt on the surface of the pressure roller body, reduces the labor intensity of workers, and facilitates quick unblocking of the groove to ensure a good de-bubbling effect.

[0023] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

The adjusting rod 22 inside the lifting frame 25 is fixedly fitted with a limiting block 223. The limiting block 223 is annular and serves to limit the adjustment rod 22 to rotate within the lifting frame 25, facilitating engagement and control of the moving seat 221. The top of the moving seat 221 and the through groove 222 are both cross-shaped structures. The surface of the moving seat 221 is tightly fitted with the inner wall of the through groove 222. The cross-shaped structure and the fit between the surface of the moving seat 221 and the through groove 222 ensure the stability of the moving seat 221 and improve the installation and limiting effect of the pressure roller body 11.

[0033] Example 2:

[0034] Please see Figure 1-4As shown, an anti-bubble pressure roller assembly for a sheet adhesive applicator includes a support 31 fixedly connected to the bottom of a crossbeam 21. The support 31 has a groove 32 inside, and a slider 33 is embedded inside the groove 32. The groove 32 is used to limit and guide the slider 33's movement. An electric telescopic rod 34 is fixedly connected to the bottom of the slider 33. A scraper 35 is provided on the side end of the electric telescopic rod 34. The electric telescopic rod 34 can control the scraper 35 to enter the groove 23 to remove residual adhesive and debris. Both the slider 33 and the groove 32 have a T-shaped structure. The side end of the scraper 35 is wedged into the groove 23. The T-shaped structure allows the slider 33 to be subjected to... The limit of the slide groove 32 causes the slider 33 to drive the electric telescopic rod 34 to move to the limit. The side end of the electric telescopic rod 34 is provided with an assembly groove 361. The assembly groove 361 is provided with a fixing rod 36. A tension spring 364 is fixedly connected between the fixing rod 36 and the electric telescopic rod 34. The side end of the scraper 35 is fixedly connected with an assembly block 363. The assembly block 363 is provided with a fixing hole 362. The assembly groove 361 and the assembly block 363 can be used to disassemble and replace the scraper 35 on the side end of the electric telescopic rod 34. The tension spring 364 is used to pull the fixing rod 36 to make it tightly inserted into the fixing hole 362 to complete the installation and fixation of the scraper 35.

[0035] The working principle is as follows:

[0036] When the operator needs to use the equipment, the transmission groove 227 on the side end of the required model pressure roller body 11 is fitted onto the transmission block 226. The rotating adjusting rod 22 and the limiting block 223 act as limiting blocks. Under the meshing connection between the adjusting rod 22 and the moving seat 221, the moving seat 221 moves within the through groove 222, causing the connecting block 224 to insert into the connecting groove 225. Next, the operator starts the hydraulic column 24 on the crossbeam 21 to drive the lifting frame 25, causing the pressure roller body 11 to move down and adjust the pressure on the sheet adhesive. Then, the motor 26 is started to control the pressure roller body 11 to rotate and press the sheet adhesive. Air bubbles in the sheet adhesive are squeezed into the groove 23 and gradually move with the spiral groove 23 before being discharged. After the machine stops operating, the electric telescopic rod 34 is activated to control the end of the scraper 35 to enter the groove 23. Then, the motor 26 is activated to control the rotation of the pressure roller body 11. Under the limited sliding connection between the slider 33 and the internal sliding groove 32 of the support 31, the scraper 35 will move horizontally driven by the groove 23 on the surface of the pressure roller body 11, and at the same time, all the residual glue and dirt in the groove 23 will be removed. After the fixed rod 36 is pulled to separate from the fixed hole 362, the scraper 35 can be moved to drive the assembly block 363 to separate from the assembly groove 361. The appropriate scraper 35 can be selected and installed according to the size of the groove 23 on the surface of the pressure roller body 11 of different models for cleaning. The tension spring 364 plays a pulling role to make the fixed rod 36 and the fixed hole 362 tightly inserted.
