Description

Technical Field

[0001] The utility model relates to the technical field of sponge production and strip cutting, in particular to a strip cutting device for sponge production with smooth incisions. Background Art

[0002] Sponge is a porous material with good water absorption. It is widely used in the automotive industry, battery industry, cosmetics industry, bra and underwear manufacturing industry, and high-end furniture manufacturing industry. The strip cutting device in sponge production is one of the key equipment in the sponge manufacturing process. It is used to cut continuous sponge materials into strips of specific width or length for further processing or use. Its working principle is to convey the sponge to be cut to the 5 strip cutting position and then cut it through the cutting mechanism.

[0003] A Chinese patent with publication number CN218195342U discloses a high-hardness polyurethane sponge slitting machine, which includes a base plate, a first support frame, a support plate, a connecting rod, a blade, a clamping mechanism and a propulsion mechanism. The first support frame is symmetrically arranged on one side of the base plate, a support plate is arranged between the tops of the first support frames, a propulsion mechanism is arranged on one side of the support plate, a connecting rod is arranged on the propulsion mechanism, three blades are evenly arranged on the connecting rod, and the blades are all matched with the support plate. A clamping mechanism is symmetrically arranged on one side of the support plate. The connecting rod is extended by the extension of the cylinder telescopic rod, thereby driving the blade to move forward. The sponge can be cut when the blade moves forward.

[0004] When the above patent is in use, the cylinder telescopic rod is extended to drive the connecting rod to move forward, thereby driving the blade to move forward. The sponge can be cut by the blade moving forward. However, the blade spacing of the slitting machine in the above patent is a fixed width, resulting in only sponge strips of fixed width being cut. The spacing between the blades cannot be directly adjusted according to user needs, and it is not convenient to change the width of the sponge strip. Therefore, a slitting device with a smooth incision for sponge production is proposed. Utility Model Content

Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present utility model, "multiple" means two or more, unless otherwise clearly and specifically defined.

[0028] like Figure 1-Figure 4 As shown, the utility model provides a technical solution: a slitting device for producing sponges with smooth cuts, comprising a slitting device platform 1, and an adjustable equidistant slitting assembly 5 located on the top of the slitting device platform 1 and a conveying roller height adjustment assembly 4 located inside the slitting device platform 1; a through groove 3 is opened on the surface of the slitting device platform 1, and a second conveying roller 8 is rotatably installed inside the through groove 3, and a second fixed block 402 and a mounting block 7 are rotatably connected to the left and right sides of the second conveying roller 8.

[0029] The adjustable equidistant strip cutting component 5 includes a first motor 501, the output end of the first motor 501 is fixedly connected to a bidirectional screw rod 502, the left and right sides of the bidirectional screw rod 502 are threadedly connected to two groups of guide assembly seats 506, the middle part of the bidirectional screw rod 502 is rotatably connected to a group of guide assembly seats 506, and the bottom of each group of guide assembly seats 506 is fixedly installed with a cylinder 504, the output end of the cylinder 504 is fixedly connected to a cutter seat 503, and the bottom of the cutter seat 503 is installed with a cutter 505 by bolts. By starting the first motor 501, the bidirectional screw rod 502 can be driven to rotate, and then the guide assembly seat 506, the cylinder 504 and the cutter 505 can be driven to move left and right to adjust the spacing between the cutters 505. This setting improves the problem that the blade spacing of the existing strip cutting device is a fixed width, resulting in only cutting sponge strips of a fixed width, and the spacing between the blades cannot be directly adjusted according to user needs, and it is not convenient to change the width of the sponge strip.

[0030] Specifically, the conveying roller height adjustment assembly 4 includes a second fixed block 402, which is fixedly installed inside the strip cutting device platform 1, and an adjustment block 403 is rotatably installed on one side of the second fixed block 402, and a rotating shaft 407 is fixedly connected to one side of the adjustment block 403, and a second bevel gear 406 is fixedly installed on the surface of the rotating shaft 407, and a first bevel gear 405 is meshed with the top of the second bevel gear 406, and a screw body 404 is fixedly installed above the first bevel gear 405, and a first fixed block 401 is threadedly installed on the surface of the screw body 404, and a first conveying roller 2 is rotatably installed on the top of the first fixed block 401, and the other end of the first conveying roller 2 is rotatably connected to a mounting block 7, and a second motor 6 is fixedly installed on the other end of the mounting block 7, and the output end of the second motor 6 is fixedly connected to the first conveying roller 2.

[0031] Specifically, when in use, according to the thickness of the sponge to be cut, the rotating adjustment block 403 can be driven to rotate the rotating shaft 407 and the second bevel gear 406, and then the first bevel gear 405 and the screw body 404 can be driven to rotate, so as to adjust the extension height of the first fixed block 401, and finally adjust the distance between the first conveying roller 2 and the second conveying roller 8. This setting can adapt to the conveying requirements of sponges of different thicknesses, ensure the stability and reliability of the sponge cutting process, and avoid the possibility that the sponge material may be stuck between the rollers, causing the conveyor belt to be blocked. At the same time, it can reduce the wear of the sponge material and the rollers, and extend the service life of the equipment. There is no need to manually push the sponge when cutting, and the safety is high. At the same time, the conveying roller can limit one end of the sponge to avoid the sponge moving off track when cutting, thereby causing the sponge to be cut unevenly.

[0032] The working process of the utility model is as follows: when using the slitting device for producing sponges with smooth cuts, the sponge to be cut can be placed between the first conveyor roller 2 and the second conveyor roller 8 by setting up the conveyor roller height adjustment component 4, and the first conveyor roller 2 can be driven to rotate by starting the second motor 6, thereby driving the sponge to be cut to move below the cutter 505, and then the cylinder 504 is started to drive the three groups of cutters 505 to move downward to complete the sponge cutting operation; by setting up the conveyor roller height adjustment component 4, when in use, according to the thickness of the sponge to be cut, the rotating adjustment block 403 can be driven to rotate the rotating shaft 407 and the second bevel gear 406, thereby driving the first bevel gear 405 and the screw rod body 404 to rotate, thereby adjusting the protruding height of the first fixed block 401, and finally adjusting the distance between the first conveyor roller 2 and the second conveyor roller 8. This setting can adapt to sponges of different thicknesses. The transmission requirements ensure the stability and reliability of the sponge cutting process, avoid the sponge material from being stuck between the rollers, causing the conveyor belt to be blocked, and at the same time reduce the wear of the sponge material and the rollers, extend the service life of the equipment, and do not need to manually push the sponge when cutting, which is highly safe. At the same time, the transmission roller can limit one end of the sponge to avoid the sponge moving off track during cutting, thereby causing the sponge to be cut unevenly; by setting the adjustable equidistant cutting component 5, starting the first motor 501 can drive the bidirectional screw rod 502 to rotate, and then drive the guide assembly seat 506, the cylinder 504 and the cutter 505 to move left and right, and adjust the spacing between the cutters 505. This setting improves the problem that the blade spacing of the existing cutting device is fixed width, resulting in only sponge strips of fixed width being cut, and the spacing between the blades cannot be directly adjusted according to user needs, and it is not convenient to change the width of the sponge strip.
