Description

Technical Field

[0001] This utility model relates to the field of special sponge production and processing technology, specifically a cutting device for a special sponge foaming production line. Background Technology

[0002] Specialty sponges, by their very nature, are distinguished from ordinary sponges. They are sponges whose foaming properties have not been altered by chemical additives. There are many types of specialty sponges, commonly including: coarse-pore filter sponges, seaweed sponges, polyester sponges, compressed sponges, absorbent sponges, and some processed materials such as silicone sponges and ceramic sponges. During the production and processing of specialty sponges, they are formed using a sponge foaming machine. The formed sponges are generally large in volume and require cutting. Therefore, cutting devices are usually used. However, most existing cutting devices used in specialty sponge production lines do not have the function of clamping and fixing the specialty sponges in actual use. This causes the specialty sponges to easily shift during cutting, which affects the cutting quality and is therefore detrimental to their use. Hence, a cutting device for a specialty sponge foaming production line is proposed. Utility Model Content

[0012] (III) Beneficial Effects

[0013] Compared with the prior art, this utility model provides a cutting device for a special sponge foaming production line, which has the following beneficial effects:

[0014] This special sponge foaming production line uses a cutting device that transports the special sponge from front to back via a conveyor line. When cutting is required, the second servo motor on the rear side is activated to rotate the second threaded rod on the rear side. This, in turn, moves the rear clamping plate downwards to its limit position via the rear traction block, thus stopping the special sponge being transported on the conveyor line. Then, the second servo motor on the front side is activated to rotate the second threaded rod on the front side. This, in turn, moves the front clamping plate downwards to its limit position via the front traction block. At this point, the two clamping plates are positioned on the front and rear sides of the special sponge, respectively. Next, the first servo motor is activated to rotate the drive bevel gear, which in turn rotates the first threaded rod via the driven bevel gear. This causes the two moving blocks and the two clamping plates to move relative to each other until the two protective pads are tightly fitted against the front and rear sides of the special sponge, clamping and fixing the sponge in place. This minimizes displacement during cutting and ensures the cutting quality of the special sponge. Attached Figure Description

[0022] A drive assembly 11 is fixedly installed on the top of the rectangular block 7, with one end extending into the interior of the rectangular groove 8 and fixedly connected to the outside of the first threaded rod 9. The drive assembly 11 includes a first servo motor 111. The first servo motor 111 is fixedly installed on the top of the rectangular block 7. The model of the first servo motor 111 may be IHSS57-36-20. The output shaft of the first servo motor 111 extends into the interior of the rectangular groove 8 and is fixedly installed with a drive bevel gear 112 located above the first threaded rod 9. A driven bevel gear 113 is fixedly installed on the outside of the first threaded rod 9, located between the two moving blocks 10 and with one end meshing with the drive bevel gear 112.

[0024] All electrical components mentioned in this article are electrically connected to the controller and power supply. The controller can be a conventional known device such as a computer. The control circuit of the controller can be implemented by a person skilled in the art through simple programming. The power supply is also common knowledge in the art. Therefore, this utility model will not explain the control method and circuit connection in detail.

[0025] In use, the special sponge is conveyed from front to back via conveyor line 1. When the special sponge needs to be cut, the rear second servo motor 14 is started to drive the rear second threaded rod 16 to rotate, which in turn drives the rear clamping plate 12 to move downward to its limit position via the rear traction block 17. This stops the special sponge being conveyed on conveyor line 1. Then, the front second servo motor 14 is started to drive the front second threaded rod 16 to rotate, which in turn drives the front clamping plate 12 to move downward to its limit position via the front traction block 17. At this point, the two clamping plates 12 are located on the front and rear sides of the special sponge, respectively. Then, the first servo motor 111 is started to drive the drive bevel gear 112 to rotate, which in turn drives the first threaded rod 9 to rotate via the driven bevel gear 113. This causes the two moving blocks 10 and the two clamping plates 12 to move relative to each other until the two protective pads 13 are respectively... The special sponge is tightly fitted to its front and back sides to clamp and fix it, thus minimizing displacement during cutting and ensuring the cutting quality. Then, the electrothermal cutting blade 6 and two electric telescopic rods 5 are activated to move the electrothermal cutting blade 6 downwards to cut the special sponge. After cutting, the electrothermal cutting blade 6 is turned off, and the two electric telescopic rods 5 are activated to move the electrothermal cutting blade 6 upwards to reset it. Simultaneously, the first servo motor 111 is activated to rotate in the opposite direction, causing the two moving blocks 10 and two clamping plates 12 to move in opposite directions, thus releasing the fixation of the special sponge. Finally, the two second servo motors 14 are activated to move the two clamping plates 12 upwards to reset it, completing the cutting of a single special sponge. The cut special sponge can then be conveyed backwards via the conveyor line 1.

[0026] In summary, the cutting device in this special sponge foaming production line transports the special sponge from front to back via conveyor line 1. When cutting is required, the rear second servo motor 14 is activated to rotate the rear second threaded rod 16, which in turn moves the rear clamping plate 12 downwards to its limit position via the rear traction block 17. This stops the special sponge being transported on conveyor line 1. Then, the front second servo motor 14 is activated to rotate the front second threaded rod 16, which in turn moves the front clamping plate 12 downwards to its limit position via the front traction block 17. At this point, the two clamping plates 12 are positioned on the front and rear sides of the special sponge, respectively. Then, the cutting process can begin. The first servo motor 111 is started to drive the drive bevel gear 112 to rotate, which in turn drives the first threaded rod 9 to rotate through the driven bevel gear 113. This causes the two moving blocks 10 and the two clamping plates 12 to move relative to each other until the two protective pads 13 are tightly attached to the front and rear sides of the special sponge. This clamps and fixes the special sponge, thus minimizing displacement during cutting and ensuring the cutting quality of the special sponge. This solves the problem that most existing special sponge production line cutting devices do not have the function of clamping and fixing special sponges, which leads to displacement of the special sponge during cutting and affects the cutting quality, making it unsuitable for use.
