Description

Technical Field

[0001] The utility model relates to the technical field of polyurethane sponges, in particular to a polyurethane sponge processing and production device. Background Art

[0002] Polyurethane sponge has the properties of heat preservation, heat insulation, sound absorption, shock absorption, flame retardancy, anti-static, etc., so it is widely used. In the processing and production of polyurethane sponge, polyurethane sponge is mostly foamed in a foaming mold. However, most of the existing polyurethane sponges are large in size after foaming, and workers need to cut them according to actual needs. At present, there are still the following deficiencies in cutting polyurethane sponge:

[0003] 1. Manual cutting method: if a single person operates, he needs to hold the polyurethane sponge with one hand and operate the knife with the other hand, which is very inconvenient and seriously affects the cutting efficiency of the polyurethane sponge. If multiple people cooperate in the operation, it takes up manpower;

[0004] 2. During the cutting process, since the cutting force is completely dependent on the tool, if the tool is not sharp enough, it will not only seriously affect the cutting efficiency of the polyurethane sponge, but also easily cause irregular cutting edges, affecting product quality;

[0005] 3. Whether it is manual cutting or mechanical cutting, the polyurethane sponge is very easy to deform during the cutting process, especially the contact part between the cutter and the polyurethane sponge. Nowadays, there is a lack of devices to reinforce the polyurethane sponge structure during cutting, which seriously affects the cutting quality;

[0006] 4. The existing cutting equipment has a single fixed structure and cannot meet the cutting and fixing requirements of polyurethane sponges of different sizes;

DETAILED DESCRIPTION

[0038] The technical solution of the present invention will be described below in conjunction with the drawings in the embodiments of the present invention. In the description, it should be understood that if there are terms such as "upper", "lower", "front", "back", "left", "right", etc. indicating directions or positional relationships, they only correspond to the drawings of the present invention and are for the convenience of describing the present invention, rather than indicating or implying that the device or element referred to must have a specific direction.

[0039] Please refer to the instruction manual Figure 1-7, the utility model provides a technical solution:

[0040] Embodiment 1, a polyurethane sponge processing and production device, including a workbench 9, a plurality of legs 10 are provided at the bottom of the workbench 9, an end baffle 1 for blocking and limiting the end of the polyurethane sponge is provided at one end of the upper surface of the workbench 9, and side baffles 3 that can be synchronously moved toward or away from each other and are used to block and limit the two sides of the polyurethane sponge are provided on both sides of the upper surface of the workbench 9. Specifically, the side baffles 3 are arranged perpendicular to the end baffles 1. In order to realize the synchronous movement of the two side baffles 3 toward or away from each other, a side plate surface of the end baffle 1 facing the side baffle 3 is provided along the length direction of the end baffle 1. A slide groove 12 is provided, and a slider 14 is provided at one end of the side baffle 3 close to the end baffle 1, which is slidably matched with the slide groove 12. A driving mechanism 2 is provided in the slide groove 12 to drive the two side baffles 3 to move synchronously toward or away from each other. The driving mechanism 2 includes a bidirectional screw rod 13. A bidirectional screw rod 13 is rotatably installed in the slide groove 12 along the axial direction of the slide groove 12. The sliders 14 at the ends of the two side baffles 3 are provided with screw holes 15 that penetrate the slider 14 and are respectively threadedly connected to one end of the bidirectional screw rod 13. One end of the bidirectional screw rod 13 penetrates the slide groove 12, and a rotating handle 11 is provided at its end.

[0041] The side walls on both sides of the workbench 9 are provided with side slide grooves 8 arranged in the same direction as the length direction of the side baffle 3. The two sides of the workbench 9 are provided with sliding support members 7 that can slide back and forth along the side slide grooves 8 toward the end baffle 1 and can be adjusted up and down. Specifically, the sliding support member 7 includes an outer outer rod 19 and an inner lifting rod 16. The outer outer rod 19 is provided with an inner lifting rod 16 that can be adjusted up and down. A limiting screw hole A17 is provided on one side of the upper part of the outer outer rod 19. The inner thread of the limiting screw hole A17 is connected with a limiting screw A18 for resisting and limiting the inner lifting rod 16. A side slider 20 that slidably cooperates with the side slide groove 8 is provided on one side of the lower part of the outer outer rod 19;

[0042] The upper ends of the two sliding support members 7 are provided with a limit pressing plate 4 which is parallel to the upper surface of the workbench 9 and is used to press and limit the upper surface of the polyurethane sponge. The upper end of the lifting inner rod 16 in the sliding support member 7 is fixedly connected to the limit pressing plate 4. The side of the limit pressing plate 4 away from the end baffle 1 is provided with a movable block 5 which can slide and adjust along the length direction of the limit pressing plate 4. Specifically, the upper and lower surfaces of the side of the limit pressing plate 4 away from the end baffle 1 are provided with grooves 22 arranged along the length direction of the limit pressing plate 4. One end of the movable block 5 is provided with a bayonet 26 adapted to the limit pressing plate 4, and the upper and lower inner walls of the bayonet 26 are provided with inner folding edges 27 which slide and match with the corresponding grooves 22.

[0043] The movable block 5 is detachably provided with a cutting assembly 6 for cutting the polyurethane sponge. Specifically, the cutting assembly 6 includes a cutting knife 28 which is perpendicular to the upper surface of the workbench 9 and whose lower end contacts the upper surface of the workbench 9. The movable block 5 is provided with a through hole 25 which penetrates the movable block 5 and is adapted to the cutting assembly 6. The cutting knife 28 passes through the through hole 25 in a vertical shape. The length of the cutting knife 28 is greater than the distance between the limiting pressing plate 4 and the upper surface of the workbench 9.

[0044] When cutting the polyurethane sponge, the staff first places the polyurethane sponge to be cut on the upper part of the workbench 1, so that one end of it contacts the end baffle 1, and then rotates the handle 11, and uses the double-rest screw rod 13 to drive the two side baffles 3 to move toward each other, so that the two side baffles 3 are clamped on both sides of the polyurethane sponge while ensuring the flatness of the polyurethane sponge. After the polyurethane sponge is clamped and limited, the staff adjusts the extension amount of the lifting inner rod 16 so that the limiting pressure plate 4 is just on the upper surface of the polyurethane sponge, and then tightens the limiting screw A18 to fix it. Finally, according to the cutting requirements, the staff first pushes the movable block 5 to the cutting position, and then pushes the limiting pressure plate 4 to slide toward the end baffle 1. As the limiting pressure plate 4 slides, the limiting pressure plate 4 cooperates with the end baffle 1 and the two side baffles 3 to ensure that the polyurethane sponge maintains a stable structure. When the cutting knife 28 is cutting, the limiting pressure plate 4 located in front of the cutting knife 28 cooperates with the end baffle 1 and the two side baffles 3 to ensure that the polyurethane sponge maintains a stable structure, thereby effectively avoiding the deformation of the polyurethane sponge during the cutting process and greatly improving the cutting quality.

[0045] In the second embodiment, during the cutting operation, since the cutting is completely dependent on the cutting knife 28, if the cutting knife 28 is not sharp enough during the cutting process, it will not only affect the cutting efficiency, but also easily cause the polyurethane sponge cutting part to deform during the cutting process, affecting the cutting quality. In order to improve the cutting efficiency and cutting quality of the polyurethane sponge, the cutting assembly 6 also includes a mounting rod 31 which is perpendicular to the upper surface of the workbench 9 and has an isosceles trapezoidal structure in cross section. The narrow surface of the mounting rod 31 is arranged toward the end baffle 1. A slot 29 is arranged along the length direction of the mounting rod 31 and is used to install the cutting knife 28 on the narrow surface of the mounting rod 31. The through port 25 is adapted to the cutting assembly 6. The inclined surfaces on both sides of the mounting rod 31 are provided with sand surfaces 30 for grinding the polyurethane sponge cutting part.

[0046] During the cutting operation, the mounting rod 31 can expand the gap of the polyurethane sponge after cutting. The expansion of the mounting rod 31 can greatly reduce the subsequent cutting resistance of the cutting knife 28 and improve the cutting efficiency. The sand surface 30 on the inclined surfaces on both sides of the mounting rod 31 can also grind the edges after cutting, thereby greatly improving the cutting quality.

[0047] Embodiment 3: During the cutting operation, it is often necessary to repeatedly adjust the position of the cutting assembly 6 according to the cutting requirements, and the adjustment of the cutting assembly 6 needs to be driven by the movable block 5. In order to ensure the accurate and efficient adjustment of the cutting assembly 6 during the adjustment, the upper surface of the limiting pressure plate 4 is provided with a scale 21 arranged along the length direction of the limiting pressure plate 4, and the scale 21 can be arranged adjacent to the groove 22, so as to facilitate the staff to accurately adjust the position of the cutting assembly 6;

[0048] After the adjustment is completed, in order to ensure that the cutting assembly 6 remains in a fixed position and facilitate subsequent cutting, a limiting screw hole B24 is provided on the upper surface of the movable block 5 and penetrates to the bayonet 26. The inner thread of the limiting screw hole B24 is connected to a limiting screw B23 for limiting the movable block 5.

[0049] The parts of the present invention that are not described in detail are prior art. It is obvious to those skilled in the art that the present invention is not limited to the details of the above-mentioned exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the above-mentioned embodiments should be regarded as exemplary and non-restrictive.
