Description

Technical Field

[0001] This utility model relates to the field of nonwoven fabric processing equipment technology, and more specifically, to a nonwoven fabric processing edge cutting device. Background Technology

[0002] Nonwoven fabrics are widely used in many fields such as modern industry, medical care, hygiene, and daily life. With the increasing demand for diversified nonwoven fabric products, the performance requirements for nonwoven fabric processing equipment are also increasing. As a key link in the nonwoven fabric processing process, edge cutting requires the use of edge cutting devices, namely nonwoven fabric slitting machines.

[0003] Existing nonwoven fabric slitting machines often produce fuzzy edges when cutting loosely textured, long, and fine nonwoven fabrics. If the blade edge is not sharp enough, this can easily lead to fraying. Therefore, to ensure the quality of cutting loosely textured, long, and fine nonwoven fabric edges, operators need to frequently disassemble and reassemble the blade, and then grind the blade edge to ensure its sharpness. This operation is extremely cumbersome. In view of this, we propose a nonwoven fabric processing edge cutting device. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a non-woven fabric processing edge cutting device to solve the technical problem that the current non-woven fabric slitting machine is not convenient for grinding the blade edge of the cutter head.

[0006] The triangular grinding plate is composed of two sets of U-shaped grinding plates. The two sets of U-shaped grinding plates are rotatably arranged on the lifting frame. The two sets of U-shaped grinding plates are arranged in a triangular cross shape. Each set of U-shaped grinding plates has a top plate on top, and two sets of symmetrical springs are arranged between the top plates of the two sets of U-shaped grinding plates.

[0007] This invention incorporates a grinding structure on the cutter head frame of a nonwoven fabric slitting machine. The triangular grinding plates within this structure are positioned above the cutter head. Therefore, when the nonwoven fabric slitting machine is cutting loosely textured, long, and fine-fibered nonwoven fabric, the operator can directly control the drive structure to lower two sets of lifting frames. This allows the triangular grinding plates on the lifting frames to contact the cutting edge of the cutter head. During the rotation of the cutter head, the triangular grinding plates directly grind the cutting edge, ensuring its sharpness. Furthermore, it eliminates the need for manual grinding after disassembling the cutter head, significantly improving the device's performance. The new triangular grinding plate is composed of two sets of U-shaped grinding plates, each rotatably connected to a lifting frame. The top plates of the two sets of U-shaped grinding plates are connected by springs. Under the pull of the springs, the top angle of the two sets of U-shaped grinding plates can be adaptively changed, allowing the two sets of U-shaped grinding plates to fit tightly against both sides of the cutter head edge, ensuring a good grinding effect. Furthermore, the two sets of U-shaped grinding plates are arranged in a triangular, intersecting pattern, achieving a multi-stage, staggered grinding effect on both sides of the cutter head edge, further improving the grinding effect of the triangular grinding plate on the cutter head edge.

[0008] Preferably, the bottom sides of the mounting frame are arc-shaped, and several sets of equidistant rollers are rotatably arranged on the bottom sides of the mounting frame, with the rollers contacting the sides of the nonwoven fabric slitting machine cutter disc.

[0009] Preferably, the mounting frame has symmetrical sliding slots on both sides, and a concave frame is slidably arranged inside the sliding slot, the concave frame being connected to the lifting frame.

[0010] Preferably, the drive structure includes a transmission rod, an electro-hydraulic push rod, and a lifting plate. The transmission rod is slidably arranged on the bracket, the electro-hydraulic push rod is arranged at one end of the top of the bracket, and the piston end of the electro-hydraulic push rod is connected to the transmission rod. The lifting plate is arranged on the lifting frame and passes through the bracket.

[0011] Preferably, the lifting plate has a guide groove inside, the top of the guide groove is inclined, and a triangular guide block is arranged at the position where the transmission rod passes through the lifting plate. The triangular guide block is slidably connected to the top of the guide groove.

[0012] Preferably, the top of the triangular guide block is provided with a T-shaped groove, and a T-shaped slider is slidably arranged inside the T-shaped groove, the T-shaped slider being connected to the inclined surface at the top of the guide groove.

[0013] Preferably, the two ends of the transmission rod are fitted with mounting sleeves, and the mounting sleeves are arranged on the bracket.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This utility model incorporates a grinding structure on the cutter head frame of a nonwoven fabric slitting machine. The triangular grinding plate in this structure is located above the cutter head. Therefore, when the nonwoven fabric slitting machine is cutting edges of loosely textured, long, and fine-fibered nonwoven fabric, the operator can directly control the drive structure to lower the two sets of lifting frames, allowing the triangular grinding plate on the lifting frame to contact the cutter head's cutting edge. During the rotation of the cutter head, the triangular grinding plate directly grinds the cutting edge, ensuring its sharpness. Furthermore, it eliminates the need for manual grinding of the cutter head, greatly improving the device's performance and solving the technical problem of current nonwoven fabric slitting machines being inconvenient for grinding the cutter head's cutting edge. Therefore, this utility model possesses the advantage of automatically grinding the cutter head's cutting edge.

[0016] 2. The triangular grinding plate of this utility model is composed of two sets of U-shaped grinding plates, and the two sets of U-shaped grinding plates are rotatably connected to the lifting frame. The top plates of the two sets of U-shaped grinding plates are connected by springs. Under the pull of the springs, the top angle of the two sets of U-shaped grinding plates can be pushed to adapt to the change, so that the two sets of U-shaped grinding plates can fit tightly with the two sides of the cutting edge of the cutter head, ensuring the grinding effect. Furthermore, the two sets of U-shaped grinding plates are arranged in a triangular cross shape, thereby achieving a multiple grinding effect of left and right staggered on both sides of the cutting edge of the cutter head, thereby further improving the grinding effect of the triangular grinding plate on the cutting edge of the cutter head.

[0026] like Figures 1 to 7 As shown, the present invention relates to a non-woven fabric processing edge trimming device, including a non-woven fabric slitting machine 1, a grinding structure 2 arranged on the cutter head frame of the non-woven fabric slitting machine 1, the grinding structure 2 including a bracket 3, the bracket 3 arranged on the cutter head frame of the non-woven fabric slitting machine 1, a mounting frame 301 corresponding to the cutter head of the non-woven fabric slitting machine 1 arranged at the bottom of the bracket 3, a lifting frame 5 slidably arranged inside the mounting frame 301, a triangular grinding plate 6 arranged at the bottom opening of the lifting frame 5, and a driving structure 4 arranged at the top of the bracket 3;

[0027] When the nonwoven fabric slitting machine 1 cuts the edges of loosely textured nonwoven fabric with long and fine fibers, the operator can directly control the drive structure 4 to drive the two sets of lifting frames 5 to descend, so that the triangular grinding plates 6 on the lifting frames 5 come into contact with the cutting edge of the cutter head. During the rotation of the cutter head, the triangular grinding plates 6 can directly grind the cutting edge, thus ensuring the sharpness of the cutting edge of the cutter head. Moreover, there is no need to disassemble the cutter head for manual grinding, which greatly improves the performance of the device.

[0028] Specifically, the bottom sides of the mounting frame 301 are arc-shaped, and several sets of equidistant rollers 304 are rotatably arranged on the bottom sides of the mounting frame 301. The rollers 304 contact the sides of the cutter head of the nonwoven fabric slitting machine 1. The mounting frame 301 can achieve stability by contacting the roller surfaces on both sides of the cutter head of the nonwoven fabric slitting machine 1 through the rollers 304. Then, the mounting frame 301 can support the lifting frame 5 to prevent the lifting frame 5 from deforming, thereby ensuring that the lifting frame 5 can stably drive the triangular grinding plate 6 to rise and fall to grind the cutting edge of the cutter head.

[0029] Furthermore, the mounting frame 301 has symmetrical sliding slots 302 on both sides, and a concave frame 303 is slidably arranged inside the sliding slot 302. The concave frame 303 is connected to the lifting frame 5. With the cooperation of the sliding slot 302 and the concave frame 303, the lifting frame 5 can be slidably installed in the mounting frame 301.

[0030] Furthermore, the drive structure 4 includes a transmission rod 401, an electro-hydraulic push rod 402, and a lifting plate 403. The transmission rod 401 is slidably arranged on the bracket 3, the electro-hydraulic push rod 402 is arranged at one end of the top of the bracket 3, and the piston end of the electro-hydraulic push rod 402 is connected to the transmission rod 401. The lifting plate 403 is arranged on the lifting frame 5 and passes through the bracket 3. A guide groove 407 is opened inside the lifting plate 403. The top of the guide groove 407 is inclined. A triangular guide block 404 is arranged at the position where the transmission rod 401 passes through the lifting plate 403. The triangular guide block 404 is slidably connected to the top of the guide groove 407. When the electro-hydraulic push rod 402 drives the transmission rod 401 to move, the triangular guide block 404 will move in the guide groove 407, thereby driving the lifting plate 403 to move up and down. Then the lifting plate 403 can drive the lifting frame 5 to move up and down.

[0031] It is worth noting that the top of the triangular guide block 404 is provided with a T-shaped groove 405, and a T-shaped slider 406 is slidably arranged inside the T-shaped groove 405. The T-shaped slider 406 is connected to the top inclined surface of the guide groove 407. With the cooperation of the T-shaped groove 405 and the T-shaped slider 406, the triangular guide block 404 can be slidably connected to the top inclined surface of the guide groove 407. Therefore, when the triangular guide block 404 moves, it will drive the lifting plate 403 to move up and down.

[0032] It is worth mentioning that the transmission rod 401 is fitted with mounting sleeves 408 at both ends, and the mounting sleeves 408 are arranged on the bracket 3; with the cooperation of the mounting sleeves 408, the transmission rod 401 can slide left and right on the bracket 3.

[0033] In an embodiment of this utility model, the triangular grinding plate 6 is composed of two sets of U-shaped grinding plates 601. The two sets of U-shaped grinding plates 601 are rotatably arranged on the lifting frame 5. The two sets of U-shaped grinding plates 601 are arranged in a triangular cross shape. A top plate 602 is arranged on the top of each set of U-shaped grinding plates 601, and two sets of symmetrical springs 603 are arranged between the top plates 602 on the top of the two sets of U-shaped grinding plates 601.

[0034] Under the pull of the spring 603, the top angle of the two sets of U-shaped grinding plates 601 can be adjusted adaptively, so that the two sets of U-shaped grinding plates 601 can fit tightly with the two sides of the cutting edge of the cutter head, ensuring the grinding effect. Furthermore, the two sets of triangularly arranged U-shaped grinding plates 601 can achieve multiple grinding effects on the two sides of the cutting edge of the cutter head by alternating left and right positions, thereby further improving the grinding effect of the triangular grinding plate 6 on the cutting edge of the cutter head.

[0035] Working principle: This embodiment provides a non-woven fabric processing edge cutting device. First, when the non-woven fabric slitting machine 1 cuts the edges of the loosely textured non-woven fabric with long and fine fibers, the operator can directly control the drive structure 4 to drive the two sets of lifting frames 5 to descend, so that the triangular grinding plate 6 on the lifting frame 5 contacts the cutting edge of the cutter head. During the rotation of the cutter head, the triangular grinding plate 6 can directly grind its cutting edge, thereby ensuring the sharpness of the cutting edge of the cutter head. Moreover, there is no need to disassemble the cutter head for manual grinding, which greatly improves the performance of the device.

[0036] Secondly, under the pull of the spring 603, the top angle of the two sets of U-shaped grinding plates 601 can be adjusted adaptively, so that the two sets of U-shaped grinding plates 601 can fit tightly with the two sides of the cutting edge of the cutter head, ensuring the grinding effect. Furthermore, the two sets of triangularly arranged U-shaped grinding plates 601 can achieve multiple grinding effects on the two sides of the cutting edge of the cutter head by alternating left and right positions, thereby further improving the grinding effect of the triangular grinding plate 6 on the cutting edge of the cutter head.
