Description

Technical Field

[0001] This utility model relates to the field of memory foam punching technology, and in particular to a punching machine for processing memory foam. Background Technology

[0002] Memory foam refers to polyether-type polyurethane foam with slow rebound mechanical properties. It is a special type of foam. Memory foam has a soft feel. When people sit on memory foam lumbar support, it initially deforms, and then the resistance disappears. The back pain that should occur after sitting for a long time is also nowhere to be found. Moreover, memory foam has leading performance in terms of absorbing impact, reducing vibration, and releasing low rebound force. It is the cushioning material to protect astronauts' bodies during spacecraft landing and the premium material for packaging valuable instruments.

[0003] To enhance the breathability and resilience of memory foam, reduce its overall weight, and increase its softness, memory foam is typically perforated by punching multiple round holes in a single pass using a punching machine.

[0004] Memory foam is highly elastic, stretchable, and prone to deformation. When the punch cuts in, the uneven external force on the surrounding tissue of the foam can cause it to stretch and twist excessively in all directions, resulting in rough edges and distorted shapes of the punched holes. Such holes cannot achieve a regular circle, thus deviating from the expected shape and affecting the uniformity of the product's appearance. Based on the above problems, this application proposes a punching machine for processing memory foam. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a punching machine for processing memory foam, which solves the problems mentioned in the background art.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Reference Figure 1-5A punching machine for processing memory foam includes a mounting frame 1. A conveying assembly is installed inside the mounting frame 1. The conveying assembly includes a drive motor 2 fixedly mounted on the rear side of the mounting frame 1. A drive roller 3 is fixedly mounted on the output end of the drive motor 2. A conveyor belt 4 is meshed on the surface of the drive roller 3. A driven roller 5 is meshed inside the conveyor belt 4. The driven roller 5 is rotatably mounted inside the mounting frame 1. The drive motor 2 drives the drive roller 3 to rotate. The drive roller 3, in conjunction with the driven roller 5, causes the conveyor belt 4 to convey the memory foam. The left and right conveyor belts 4 support the unpunched and punched portions of the memory foam. The two conveyor belts 4 prevent the memory foam ends from sagging and falling off the conveyor belts 4 and the punched portion. The perforated plate 12 slides down. A limit component is provided at the top of the mounting bracket 1. A perforated plate 12 is fixedly installed between the opposing surfaces of the mounting bracket 1. A punching hole 13 is provided through the top of the perforated plate 12. A support column 14 is fixedly installed at the top of the perforated plate 12. A fixing plate 15 is fixedly installed at the top of the support column 14. A hydraulic push rod 16 is fixedly installed at the top of the fixing plate 15. A movable plate 17 is fixedly installed at the output end of the hydraulic push rod 16. A guide sleeve 18 is fixedly installed inside the movable plate 17. The guide sleeve 18 slides on the surface of the support column 14. A punching cutter 19 is fixedly installed at the bottom of the movable plate 17. The number of punching holes 13 and punching cutters 19 is the same. The punching holes 13 and punching cutters 19 are vertically aligned. Downward-pressing fixing components are provided on both the left and right sides of the movable plate 17. The fixing assembly includes movable frames 20 fixedly installed on the left and right sides of the movable plate 17. A mounting column 21 is slidably disposed inside the movable frame 20. A limit plate 22 overlaps and is disposed on the surface of the mounting column 21. A fixing nut for fixing the limit plate 22 is threaded at the top of the mounting column 21. A connecting frame 23 is fixedly disposed at the bottom of the mounting column 21. A spring 24 connects the top of the connecting frame 23 and the bottom of the movable frame 20. A compaction roller 25 is fixedly disposed inside the connecting frame 23. A hydraulic push rod 16 drives the movable frame 20 and the punching cutter 19 downwards via the movable plate 17, causing the compaction roller 25 to first contact the memory foam. As the movable plate 17 drives the movable frame 20 and the punching cutter 19 downwards, the movable frame 20 and the connecting frame 23 press against the spring 24. Compression causes the punch 19 to work with the punching hole 13 to punch holes in the memory foam. After the memory foam is punched, the hydraulic push rod 16 moves the punch 19 and the moving frame 20 upward via the moving plate 17. This causes the moving frame 20 to slide on the surface of the mounting post 21, keeping the compressed foam pressed by the compaction roller 25. This allows the punch 19 to move out of the compressed foam, and the memory foam will not move upward with the punch 19. By removing the fixing nut, the mounting post 21 can be removed from inside the moving frame 20, allowing the spring 24 to be replaced. This facilitates the quick replacement of damaged springs 24, ensuring that the punched holes in the memory foam meet the usage standards and preventing situations where non-standard holes render some memory foam unusable.This ensures the performance of the memory foam during use.

[0023] Specifically, the limiting component includes an adjusting plate 6 overlapping the top of the mounting frame 1. An adjusting groove 7 is provided through the top of the adjusting plate 6. A fixing stud 8 is overlapping inside the adjusting groove 7. The fixing stud 8 is fixedly installed on the top of the mounting frame 1. An internal thread cap 9 is provided on the surface of the fixing stud 8. An mounting plate 10 is fixedly installed on one side of the fixing stud 8. A guide roller 11 is rotatably installed inside the mounting plate 10. Loosening the internal thread cap 9 causes the adjusting plate 6 to move back and forth through the mounting plate 10, so that the mounting plate 10 drives the guide roller 11 to contact the memory foam. The internal thread cap 9 is then tightened on the fixing stud 8, which facilitates the guide roller 11 to guide the memory foam and avoids deviations in the punched hole position caused by deviations during the memory foam transportation process, making the punching position of the memory foam more accurate.

[0024] Specifically, the collection component includes a collection box 26 fixedly installed at the bottom of the perforated plate 12. A discharge plate 27 is fixedly installed inside the collection box 26. The discharge plate 27 is composed of two inclined plates and is made of metal. Discharge ports 28 are provided through the front and rear sides of the collection box 26. When the punching knife 19 punches the memory foam, the punched waste enters the collection box 26 through the punching hole 13 and falls onto the discharge plate 27. The discharge plate 27, composed of two inclined plates, allows the waste punched out of the memory foam to slide down automatically and be discharged from the collection box 26 through the discharge port 28, thereby avoiding the accumulation of waste inside the collection box 26. Furthermore, by setting up a waste conveying device on the outside, the waste can be uniformly processed.

[0025] The punching machine for memory foam processing is connected to a 220V mains power supply, and the main controller can be a conventional known device such as a computer for control.

[0026] In use: Place the memory foam to be punched on top of the conveyor belt 4. The drive motor 2 drives the output end to rotate the drive roller 3. The drive roller 3 drives the driven roller 5 to rotate through the conveyor belt 4, so that the conveyor belt 4 transports the memory foam. When the memory foam reaches the position to be punched, the hydraulic push rod 16 drives the output end to move the moving plate 17 downward. The moving plate 17 drives the guide sleeve 18 to slide on the surface of the support column 14, so that the moving plate 17 drives the moving frame 20 and the punching cutter 19 to move downward. So that the compaction roller 25 first contacts the memory foam. As the moving plate 17 moves downward, it continues to drive the moving frame 20 downward. The movement causes the moving frame 20 and connecting frame 23 to compress the spring 24, which in turn fixes the memory foam with the compaction roller 25. As the moving plate 17 continues to move downward, the punching knife 19 works with the punching hole 13 to punch the memory foam. After the memory foam is punched, the hydraulic push rod 16 drives the output end moving plate 17 to reset, causing the moving plate 17 to drive the punching knife 19 to move upward. Since the squeezed foam is still pressed by the compaction roller 25, the punching knife 19 moves out of the squeezed foam, and the memory foam does not move upward with the punching knife 19. Then, the conveyor belt 4 drives the memory foam to move, thereby punching the next position of the squeezed foam.
