Description

Technical Field

[0001] This utility model relates to the field of punching devices, specifically a punching device for breathable wallpaper. Background Technology

[0002] In the field of interior decoration, breathable wallpaper is widely used because it can effectively regulate indoor humidity and improve air circulation, creating a healthier and more comfortable environment for residents. However, the breathability of breathable wallpaper largely depends on the evenly distributed air pores on its surface. Therefore, the perforation process of the wallpaper is particularly crucial.

[0003] Traditional perforation methods for breathable wallpaper have many drawbacks. Some manual perforation methods are not only inefficient and difficult to meet the needs of large-scale production, but also make it difficult to ensure consistent perforation position and depth, resulting in inconsistent breathability of the wallpaper and affecting product quality.

[0004] While some early mechanical drilling devices improved drilling efficiency to a certain extent, they also had many problems due to imperfect design. For example, during the drilling process, the wallpaper was not well fixed, and the wallpaper was prone to displacement, causing deviations in the drilling position and reducing the product yield. To address this, we have proposed a breathable wallpaper drilling device. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a perforation device for breathable wallpaper, which solves the aforementioned problems.

[0006] To achieve the above-mentioned objectives, this utility model provides the following technical solution: a perforation device for breathable wall coverings, comprising a U-shaped mounting bracket, two guide rollers rotatably mounted on the inner side of the U-shaped mounting bracket, a horizontal fixing plate fixedly mounted on the inner side of the U-shaped mounting bracket, the horizontal fixing plate being located above the two guide rollers, a perforation assembly being provided on the horizontal fixing plate, and a support assembly being provided on the inner side of the U-shaped mounting bracket corresponding to the lower part of the horizontal fixing plate.

[0007] Preferably, the support assembly includes an inner wall fixing plate, an elastic support structure, and two fitting fixing blocks. The inner wall fixing plates are fixedly installed on both sides of the inner wall of the U-shaped mounting bracket. Two fitting fixing blocks are fixedly installed between the two inner wall fixing plates. Two elastic support structures are provided between the two inner wall fixing plates. The two elastic support structures are respectively located on the opposite sides of the two fitting fixing blocks.

[0008] Preferably, the elastic support structure includes a spring, a slider, and a support shaft. A rectangular groove is provided on the inner wall fixing plate. The spring is fixedly installed inside the rectangular groove. The slider is fixedly installed at the upper end of the spring. The slider is in close contact with the inside of the spring. The slider is rotatably connected to the support shaft.

[0009] Preferably, the punching assembly includes a strip connecting plate and punching heads. The strip connecting plate is disposed above the bonding and fixing blocks, and multiple sets of punching heads are equidistantly installed on the bottom of the strip connecting plate. The positions of the multiple sets of punching heads correspond to the gap between the two bonding and fixing blocks.

[0010] Preferably, a telescopic cylinder is fixedly installed on the top of the transverse fixing plate, and the telescopic shaft of the telescopic cylinder passes through the transverse fixing plate and is fixedly connected to the top of the strip connecting plate.

[0011] Preferably, a square bottom frame block is fixedly installed at the bottom of the strip connecting plate, and the positions of multiple sets of drilling heads correspond to the hollow areas of the bottom frame block. T-shaped connecting blocks are fixedly installed at the four corners of the bottom frame block. The larger diameter end of the T-shaped connecting block is located above the strip connecting plate, and a second spring is sleeved on the T-shaped connecting block. The second spring is located between the bottom frame block and the strip connecting plate.

[0012] Compared with the prior art, this utility model provides a perforation device for breathable wallpaper, which has the following beneficial effects:

[0013] 1. The perforation device of this breathable wallpaper uses a telescopic cylinder to move the strip connecting plate downwards to make holes. The bottom frame block first contacts the breathable wallpaper and presses the perforation area. As the pressure continues to fall, the breathable wallpaper contacts two bonding and fixing blocks. During this process, the contraction and rebound of the second spring ensures that the wallpaper is always fully pressed and fixed during the perforation process, effectively preventing the wallpaper from shifting during perforation and further improving the perforation accuracy and quality.

[0014] 2. After the perforation device of this breathable wallpaper is completed, the telescopic cylinder retracts, the strip connecting plate moves upward, the spring returns, the bottom frame block is reset, and the perforation head is stored again in the hollow area of ​​the bottom frame block. This design not only protects the perforation head and prevents it from being damaged when not in use, but also fixes the position of the head, making it easier to accurately execute the next perforation operation.

[0015] 3. The perforation device of this breathable wallpaper has an elastic support structure in the support component, which consists of a spring, a slider and a support shaft. During the guidance of the wallpaper, the elastic restoring force of the spring allows the support shaft to flexibly adjust its height according to the guiding tension of the wallpaper, providing good support for the wallpaper and providing a certain amount of cushioning to prevent the wallpaper from being damaged due to hard contact.

[0016] 4. The perforation device of this breathable wallcovering, through two guide rollers rotatably installed inside the U-shaped mounting bracket, can effectively guide the breathable wallcovering to be conveyed smoothly, providing smooth material transport for subsequent perforation operations, and ensuring that the perforation work is carried out continuously and efficiently.

[0032] Guide rollers 2: There are two in total, which are rotatably installed on the inside of the U-shaped mounting bracket 1. Their function is to guide the direction of the breathable wallpaper. During the drilling process, the wallpaper first passes through the guide rollers 2 on one side, then through the support components, and finally through the guide rollers 2 on the other side, ensuring the stability of the wallpaper during the conveying process and facilitating subsequent drilling operations.

[0033] Horizontal fixing plate 3: Fixedly installed inside the U-shaped mounting bracket 1, and located above the two guide rollers 2. It serves as the mounting base for the drilling assembly, and a telescopic cylinder 4 is fixedly installed on its top to provide power for the up-and-down movement of the drilling assembly.

[0034] Telescopic cylinder 4: Installed on the top of the horizontal fixed plate 3, its telescopic shaft passes through the horizontal fixed plate 3 and is fixedly connected to the top of the strip connecting plate 11. Through its own telescopic movement, it drives the strip connecting plate 11 and the punching head 12 to move up and down, realizing the punching action on the breathable wallcovering. When punching, the telescopic cylinder 4 starts to extend, driving the punching head 12 downward to punch a hole in the wallcovering; after punching is completed, the telescopic end of the telescopic cylinder 4 retracts, driving the punching head 12 to return to its original position.

[0035] Inner wall fixing plate 5: One is fixedly installed on each of the two inner walls of the U-shaped mounting bracket 1. It is an important component of the support assembly, providing installation positions for the elastic support structure and the fitting fixing block 10, and ensuring the stability of the support assembly.

[0036] Rectangular groove 6: It is formed on the inner wall fixing plate 5 and is used to install spring 7 in the elastic support structure. It provides space for spring 7 to be accommodated so that it can work normally in the groove and realize the function of elastic support.

[0037] Spring 7: Located inside the rectangular groove 6 of the inner wall fixing plate 5, with a slider 8 fixedly installed at its upper end. It has elastic restoring force, and during normal rebound, it can make the height of the support shaft 9 higher than the bonding fixing block 10, providing elastic support for the wallcovering during the guidance process of the breathable wallcovering.

[0038] Slider 8: Fixedly connected to the upper end of spring 7 and kept in close contact with the inside of spring 7, while rotatably connected to support shaft 9. Under the action of spring 7, it can move up and down within rectangular groove 6, driving support shaft 9 to move up and down, thereby achieving support adjustment for different heights of the wallpaper.

[0039] Support shaft 9: Rotatably connected to slider 8, its height can be changed under the action of spring 7.

After punching is complete, the punch heads 12 can be stored within their hollow areas.

[0044] T-shaped connecting blocks 14: There are four in total, which are fixedly installed at the four corners of the bottom frame block 13. The end with the larger diameter is located above the strip connecting plate 11 and is fitted with spring 15. It serves to connect the bottom frame block 13 and the strip connecting plate 11, and at the same time provides an installation position for spring 15, ensuring that spring 15 can work normally between the two.

[0045] Spring 2 15: Sleeves onto T-shaped connecting block 14, located between bottom frame block 13 and strip connecting plate 11. During the drilling process, when bottom frame block 13 contacts the wallpaper and continues to press down, spring 2 15 contracts, allowing the drilling head 12 to continue descending to complete the drilling; after drilling is completed, spring 2 15 rebounds, causing bottom frame block 13 to reset, and the drilling head 12 is once again stored in the hollow area of ​​bottom frame block 13.

[0046] Working principle: The breathable wallpaper is guided first through the guide roller 2 on one side, then over the two bonding and fixing blocks 10 and the support shaft 9, and then guided downwards again through another block. After drilling, the telescopic cylinder 4 is activated, and the strip connecting plate 11 moves downwards. Then, the bottom frame block 13 contacts the breathable wallpaper, pressing down on the perforated area. As the downward pressure continues, the breathable wallpaper contacts the two bonding and fixing blocks 10, and then the strip connecting plate... As the spring 11 continues to descend, the second spring 15 contracts, and then the punching head 12 punches holes in the breathable wallpaper located in the hollow area of ​​the bottom frame block 13 and between the two fitting fixing blocks 10. After the punching is completed, the telescopic cylinder 4 retracts, the strip connecting plate 11 moves downward, the second spring 15 rebounds, the bottom frame block 13 resets, and the punching head 12 is once again stored in the hollow area of ​​the bottom frame block 13. Subsequently, the breathable wallpaper is continuously guided, and the output end of the telescopic cylinder 4 reciprocates to perform continuous punching.
