Surface micro-porous embossing roller pressing device for sealing strip

Abstract

This utility model discloses a micro-perforated embossing roller pressing device for sealing strips, applied in the field of sealing strip production. It includes a base plate with a fixed frame bolted to its top. A sliding block is slidably connected to the inner wall of the fixed frame. This utility model allows for easy replacement of the embossing roller by pressing the pressing block, which in turn causes a double-sided toothed rod to rotate. The rotation of the gear disengages the toothed rod from the fixed hole. Under the action of a second spring, the first fixed shaft causes the fixed head to disengage from one end of the embossing roller, facilitating roller removal and replacement. This method reduces workload and improves replacement efficiency. Furthermore, this utility model allows for easy pressure adjustment by rotating a turntable to rotate a bidirectional lead screw. The rotation of the bidirectional lead screw causes a transmission block to move a support rod, which in turn causes a lifting plate to move the transmission rod. The movement of the transmission rod then causes both ends of the embossing roller to move simultaneously, ensuring effective embossing.

Description

Technical Field

[0001] This utility model relates to the field of sealing strip production, and in particular to a device for microporous embossing roller pressing on the surface of sealing strips. Background Technology

[0002] Microporous embossing roller pressing of sealing strips is a specialized device that uses mechanical roller pressing to create a microporous texture structure on the surface of sealing strips. Its core technology lies in applying controllable pressure and displacement to the sealing strip material using precisely designed roller pressing dies, achieving precise shaping of the microstructure. The micropores on the sealing strip surface improve its sealing performance and service life.

[0003] Existing roller pressing devices are inconvenient for replacing embossing rollers. When it is necessary to roll micro-holes of different depths or sizes, the embossing rollers need to be replaced. However, embossing rollers are generally fixed with bolts, and replacing them requires the use of tools for assembly and disassembly, which is cumbersome, increases workload, and reduces replacement efficiency. It is also inconvenient to adjust the pressure. Generally, roller pressing devices adjust the pressure by rotating screws to move the embossing roller. The two screws are located at opposite ends of the embossing roller, and adjustment requires adjusting both screws sequentially, which is troublesome. Moreover, it is difficult to ensure that the height of the two ends of the embossing roller is consistent during adjustment, causing the embossing roller to tilt and affecting the embossing effect. In order to solve the above problems, we propose a micro-hole embossing roller pressing device for sealing strips. Utility Model Content

[0004] The purpose of this invention is to provide a micro-perforated embossing roller device for sealing strips, which has the advantages of easy replacement of the embossing roller and easy adjustment of pressure.

The fixed head is bolted together, and an embossing roller is provided between the inner walls of the fixed head. The fixed block is slidably sleeved on the surface of the sliding block, and the fixed block is slidably sleeved on the surface of the first fixed shaft. A double-sided toothed rod is slidably sleeved on the inner wall of the fixed block. A gear is meshed on the surface of the double-sided toothed rod, and the gear is rotatably connected to the inner wall of the fixed block. A snap-fit ​​toothed rod is meshed on the surface of the gear. A first spring is provided between one end of the snap-fit ​​toothed rod and the inner wall of the fixed block.

A drive mechanism is provided at one end of the second fixed shaft.

[0006] By adopting the above technical solution, pressing the pressing block causes the double-sided toothed rod to rotate, which in turn causes the gear to disengage from the locking toothed rod and the fixing hole. Under the action of the second spring, the first fixing shaft drives the fixing head to disengage from one end of the embossing roller, allowing the embossing roller to be removed and replaced. This method facilitates the replacement of the embossing roller, reduces workload, and improves replacement efficiency.

[0008] By adopting the above technical solution, the rotation of the turntable causes the bidirectional lead screw to rotate, which in turn causes the transmission block to move the support rod. The movement of the support rod causes the lifting plate to move the transmission rod, and the movement of the transmission rod causes both ends of the embossing roller to move simultaneously. This method facilitates pressure adjustment, reduces the amount of adjustment, and ensures the embossing effect.

[0009] The present invention is further configured such that: the driving mechanism includes a support roller, the support roller is rotatably sleeved with the inner wall of the fixed frame, one end of the support roller is connected to a motor through a coupling, and the motor is bolted to the surface of the fixed frame.

[0011] The present invention is further configured such that: the surfaces of the transmission block and the lifting plate are both bolted with sliders, the surfaces of the sliders are slidably connected with grooves, and the grooves are formed on the inner wall of the fixed frame.

[0012] By adopting the above technical solution, the transmission block and lifting plate are prevented from shifting by setting sliders and grooves, thus improving stability.

[0013] The present invention is further configured such that a pressing block is bolted to the top of the double-sided toothed bar.

[0014] By adopting the above technical solution, the double-sided toothed rod can be easily moved by setting up a pressing block.

[0015] The present invention is further configured such that one end of the snap-fit ​​toothed rod is wedge-shaped.

[0016] By adopting the above technical solution, one end of the snap-fit ​​toothed rod is wedge-shaped, which facilitates the fixing of the first fixed shaft.

[0017] The present invention is further configured such that a second spring is sleeved on the surface of the first fixed shaft.

[0018] By adopting the above technical solution, a second spring is provided to facilitate the separation of the fixed head from the embossing roller, making it convenient to use.

[0020] By adopting the above technical solution, a turntable is set up to facilitate the rotation of the bidirectional lead screw.

[0021] In summary, this utility model has the following beneficial effects:

[0022] 1. This utility model uses the pressing block to make the double-sided toothed rod drive the gear to rotate. The rotation of the gear causes the locking toothed rod to disengage from the fixing hole. Under the action of the second spring, the first fixing shaft drives the fixing head to disengage from one end of the embossing roller, so that the embossing roller can be removed and replaced. This method can facilitate the replacement of the embossing roller, reduce the workload, and improve the replacement efficiency.

[0023] 2. This utility model achieves the purpose of easy pressure adjustment by rotating the turntable to make the bidirectional lead screw rotate, which in turn causes the transmission block to move the support rod, which in turn causes the lifting plate to move the transmission rod, and the transmission rod to move both ends of the embossing roller simultaneously. This reduces the amount of adjustment and ensures the embossing effect. Attached Figure Description

A fixing hole 13 is provided on the surface of the first fixing shaft 4, and the fixing hole 13 is snapped with the snap-fit ​​toothed rod 11. A drive mechanism 14 is provided at one end of the second fixing shaft 5. By pressing the pressing block 26, the double-sided toothed rod 9 drives the gear 10 to rotate. The rotation of the gear 10 causes the snap-fit ​​toothed rod 11 to disengage from the fixing hole 13. Under the action of the second spring 23, the first fixing shaft 4 drives the fixing head 6 to disengage from one end of the embossing roller 7, so that the embossing roller 7 can be removed and replaced. This method can facilitate the replacement of the embossing roller 7, reduce the workload, and improve the replacement efficiency.

[0031] refer to Figure 2The drive mechanism 14 includes a support roller 20, which is rotatably sleeved with the inner wall of the fixed frame 2. One end of the support roller 20 is connected to a motor 22 via a coupling, and the motor 22 is bolted to the surface of the fixed frame 2. By setting the drive mechanism 14, it is easy to emboss.

[0032] refer to Figure 3 A pressing block 26 is bolted to the top of the double-sided toothed rod 9. The pressing block 26 facilitates the movement of the double-sided toothed rod 9.

[0033] refer to Figure 3 One end of the snap-fit ​​toothed rod 11 is wedge-shaped, which facilitates the fixing of the first fixed shaft 4.

A lifting plate 18 is hinged to the bottom of the support rod 17. A transmission rod 19 is bolted to the bottom of the lifting plate 18. The transmission rod 19 is connected to both the first fixed shaft 4 and the second fixed shaft 5. By rotating the turntable 21, the bidirectional lead screw 15 is rotated. The rotation of the bidirectional lead screw 15 causes the transmission block 16 to move the support rod 17. The movement of the support rod 17 causes the lifting plate 18 to move the transmission rod 19. The movement of the transmission rod 19 causes both ends of the embossing roller 7 to move simultaneously. This method can facilitate pressure adjustment, reduce the amount of adjustment, and ensure the embossing effect.

[0039] Brief description of the usage process: The sealing strip is passed through the support roller 20 and the embossing roller 7. The motor 22 rotates and drives the support roller 20 to rotate and convey the sealing strip. As the embossing roller 7 squeezes the sealing strip, the sealing strip moves and drives the embossing roller 7 to rotate, thus embossing the sealing strip and achieving the purpose of embossing.

[0040] Hold one end of the embossing roller and press the pressing block 26. The pressing block 26 moves, causing the double-sided toothed rod 9 to move. The double-sided toothed rod 9 moves, causing the gear 10 to rotate. The gear 10 rotates, causing the locking toothed rod 11 to move. The locking toothed rod 11 moves, causing it to disengage from the fixing hole 13. Under the action of the second spring 23, the first fixing shaft 4 drives the fixing head 6 to disengage from one end of the embossing roller 7. Remove the embossing roller 7. Install the moving end of the embossing roller 7 with the fixing head 6 on the second fixing shaft 5. Then, align the other end of the embossing roller 7 with the fixing head 6 on the first fixing shaft 4. Then, move the first fixing shaft 4 so that the fixing head 6 fixes the other end of the embossing roller 7. Under the action of the second spring 23, the locking toothed rod 11 engages with the fixing hole 13 and is fixed, thus completing the replacement and facilitating the replacement of the embossing roller 7.

[0041] Rotating turntable 21 causes the bidirectional lead screw 15 to rotate, which in turn causes the transmission block 16 to move. The movement of the transmission block 16 causes the support rod 17 to move, which in turn causes the lifting plate 18 to move. The movement of the lifting plate 18 causes the transmission rod 19 to move, which in turn causes the embossing roller 7 to move. The movement of the embossing roller 7 changes the pressure, thereby facilitating the connection of the pressure.
