Description

Technical Field

[0001] This utility model is an automatic cutting device for sponge production and processing, belonging to the field of sponge production and processing technology. Background Technology

[0002] Sponge (such as polyurethane sponge and latex sponge) is a material widely used in furniture, automotive interiors, packaging and other fields. Its production and processing require cutting large blanks into finished products of specific sizes or irregular shapes. Currently, most existing sponge cutting machines have complex structures, large volumes, large floor space, and high costs, which is not conducive to the promotion and application of sponge cutting machines.

[0003] Chinese patent CN219768513U discloses a sponge cutting machine. It measures the size of the sponge to be cut using a graduated gauge. The operator presses down on the cutting handle, and a sliding connecting plate cuts the sponge downwards under the action of the handle. After cutting, releasing the cutting handle causes the sliding connecting plate to move upwards and retract under the rebound of the cutting rebound mechanism connected above, allowing for the next cutting step. However, this sponge cutting machine uses a relatively simple cutting head. If the sponge lacks constraint during cutting, the blade will pull on the sponge fibers, resulting in uneven stress on the fibers at the cut edge, forming burrs (loose fibers) or tears (local fibers being forcibly broken). There is an urgent need for an automatic cutting device for sponge production and processing to solve these problems. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an automatic cutting device for sponge production and processing, so as to solve the problems mentioned in the background technology. This utility model can adjust the pressure during sponge cutting according to the sponge density, so as to play a reasonable pressing role and make the sponge cut evenly stressed.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: an automatic cutting device for sponge production and processing, comprising a cutting support and an adjusting side plate. Vertical poles are longitudinally welded to the front and rear sides of the upper end of the cutting support. A horizontal bar is horizontally fixed to the upper ends of the two vertical poles via flange bolts. An angle steel seat is secured to the lower end of the horizontal bar via multiple bolts. An electric telescopic rod is longitudinally installed at the lower end of the angle steel seat via flanges and bolts. A movable plate is horizontally fixed to the movable end of the electric telescopic rod. One-way wheels are installed at the four corners of the movable plate. The lower end of the movable plate is longitudinally... The device is equipped with a cutting blade. Fixed side plates are horizontally welded to the upper sides of both ends of the cutting blade. Threaded holes are formed at the upper ends of both fixed side plates, and threaded rods pass through each of the two threaded holes. Two adjusting side plates are provided, slidingly fitted to the left and right sides of the cutting blade respectively. An embedded bearing is embedded in the middle of the upper ends of both adjusting side plates. Hollow metal tubes are longitudinally welded to the front and rear sides of the upper ends of both adjusting side plates. Multiple return springs are longitudinally installed at the lower ends of both adjusting side plates, and two pressure plates are horizontally fixed to the lower ends of the multiple return springs.

[0006] Furthermore, each of the two uprights has a longitudinally formed guide groove on its inner side, and the multiple one-way wheels slide within the multiple guide grooves respectively.

[0007] Furthermore, cylindrical holes are provided on the front and rear sides of the upper ends of the two fixed side plates, and multiple hollow metal tubes slide through the multiple cylindrical holes respectively.

[0008] Furthermore, the threaded ends of the two threaded rods are respectively installed in two embedded bearings.

[0009] Furthermore, two silicone pads are respectively glued to the lower ends of the two pressure plates.

[0010] Furthermore, the electric telescopic rod is connected to an external PLC controller via a wire.

[0011] The beneficial effects of this utility model are as follows: This utility model provides an automatic cutting device for sponge production and processing. Because it incorporates a crossbar, angle steel seat, electric telescopic rod, moving plate, one-way wheel, cutting blade, fixed side plate, threaded rod, adjusting side plate, embedded bearing, return spring, pressure plate, silicone pad, and metal hollow tube, its structure is reasonable. The pressure can be adjusted according to the sponge density during cutting, achieving a reasonable compression effect. This pressure counteracts the pulling force of the cutting tool, keeping the sponge fibers relatively still at the moment of cutting, reducing tearing caused by fiber misalignment. Furthermore, the compression temporarily increases the sponge density on both sides of the cutting line (local compaction), allowing the cutting tool to "cleanly cut" the fibers rather than "tear and break" them, thus reducing burrs. It is also small in size and inexpensive, making it suitable for widespread use in small-scale sponge production facilities. Attached Figure Description

Detailed Implementation

[0018] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0019] Please see Figures 1-4This utility model provides a technical solution: an automatic cutting device for sponge production and processing, including a cutting support 1 and an adjusting side plate 13. Vertical poles 2 are longitudinally welded to the front and rear sides of the upper end of the cutting support 1. A horizontal bar 3 is horizontally fixed to the upper end of the two vertical poles 2 via flange bolts 4. An angle steel seat 5 is secured to the lower middle of the horizontal bar 3 via multiple bolts. An electric telescopic rod 6 is longitudinally installed at the lower end of the angle steel seat 5 via flanges and bolts. A movable plate 7 is horizontally fixed to the movable end of the electric telescopic rod 6. One-way wheels 9 are installed at the four corners of the movable plate 7. A cutting blade 10 is longitudinally installed at the lower end of the movable plate 7. Fixed side plates 11 are horizontally welded to the upper sides of both ends of the cutting blade 10. Threaded holes are opened at the upper ends of both fixed side plates 11. Each threaded hole has a threaded rod 12 running through it. There are two adjusting side plates 13, which slide against the left and right sides of the cutting blade 10 respectively. An embedded bearing 14 is embedded in the middle of the upper end of each of the two adjusting side plates 13. Metal hollow tubes 18 are longitudinally welded to the front and rear sides of the upper end of each of the two adjusting side plates 13. Multiple return springs 15 are longitudinally installed at the lower end of each of the two adjusting side plates 13. Two pressure plates 16 are horizontally fixed at the lower end of each of the multiple return springs 15. This design solves the problem that in the original sponge cutting machine, the cutting head is relatively simple. If the sponge lacks restraint during cutting, the blade will pull the sponge fibers, resulting in uneven force on the fibers at the cut edge, forming burrs, loose fibers, or tearing of local fibers that are forcibly broken.

[0020] As the first embodiment of this utility model: Both uprights 2 have longitudinally formed guide grooves 8 on their inner sides. Multiple one-way wheels 9 slide within these guide grooves 8, preventing the moving plate 7 from swinging left or right. Both fixed side plates 11 have cylindrical holes extending through their upper front and rear sides. Multiple hollow metal tubes 18 slide through these cylindrical holes, preventing the two adjusting side plates 13 from shifting upwards or downwards. The threaded ends of the two threaded rods 12 are respectively installed in two embedded bearings 14. Two silicone pads 17 are respectively adhered to the lower ends of the two pressure plates 16. The two silicone pads 17 have a Shore hardness of 30-50A, ensuring even pressure distribution on the sponge and preventing concentrated stress at the edges. The electric telescopic rod 6 is connected to an external PLC controller via wires. Both the electric telescopic rod 6 and the external PLC controller are existing devices, and their control principles will not be elaborated upon.

[0021] As a second embodiment of this utility model: First, adjust the pressing structure of the device according to the sponge density. Tighten the two threaded rods 12, and the two threaded rods 12 rotate and move downward in the two threaded holes. This causes the two adjusting side plates 13 to move downward through the two embedded bearings 14. During this process, multiple return springs 15, two pressure plates 16, and two silicone pads 17 can be moved downward (multiple metal hollow tubes 18 will also move downward in multiple cylindrical holes), thus changing the position of the two pressure plates 16 and the two silicone pads 17. Then, place the sponge on the cutting support 1, so that the position to be cut is at... Directly below the cutting blade 10, activate the electric telescopic rod 6. The movable end of the electric telescopic rod 6 will drive the moving plate 7, multiple one-way wheels 9, the cutting blade 10, two fixed side plates 11, two threaded rods 12, two adjusting side plates 13, multiple return springs 15, two pressure plates 16, and two silicone pads 17 to move downwards until the two silicone pads 17 are in close contact with the upper end of the sponge to be cut, so that the pressure is evenly distributed and the force is not concentrated at the edge. Until the cutting blade 10 contacts the tightly pressed sponge and cuts it, the sponge fibers can remain relatively still at the moment of cutting, reducing tearing caused by fiber misalignment.
