Description

Technical Field

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

[0002] Nonwoven fabric, also known as non-woven cloth, is a type of fabric formed without spinning or weaving. It is made by directly reinforcing a fiber web through mechanical, thermal, or chemical methods. It combines the softness of textiles with the strength of plastics, offering breathability, flexibility, lightweight properties, and wrinkle resistance. It is also disposable, environmentally friendly, and biodegradable. During production, edge-trimming equipment is used to remove excess material from both sides of the nonwoven fabric.

[0003] In the prior art, the patent announcement number CN222499814U discloses a non-woven fabric processing edge cutting device, including: a base, a processing table fixedly installed on the top of the base, and a first fixing plate fixedly installed on one side of the top of the processing table, and the number of the first fixing plates is two.

[0004] Waste generated during the edge trimming process is typically collected and disposed of through specially designed waste bins. However, in practice, the waste bins often have large gaps and voids between the collected non-woven fabric scraps, resulting in low utilization and significant space waste. Consequently, the waste bins quickly reach their capacity and become completely full. To maintain the normal operation of the production line and prevent excessive waste accumulation from affecting work efficiency, workers have to frequently clean the waste bins. This not only increases the workers' workload but may also disrupt the production process. Utility Model Content

[0005] The purpose of this invention is to provide a spherical nonwoven fabric edge-cutting device to solve the problems in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a spherical nonwoven fabric edge-cutting device, comprising a worktable, a waste bin at the bottom of the worktable, guide rollers at both ends of the worktable, nonwoven fabric between the guide rollers, edge-cutting assemblies on both sides of the worktable, the edge-cutting assembly comprising a positioning frame fixedly mounted on the worktable, a ring cutter and a ring cutter seat rotatably mounted on the positioning frame, a linkage gear fixedly mounted on one side of the ring cutter and the ring cutter seat, and two sets of linkage gears meshing together, a motor frame fixedly mounted on one side of the positioning frame, a first motor fixedly mounted on the motor frame, and the output end of the first motor fixedly mounted at the middle position of the linkage gears, and a winding mechanism provided inside the worktable.

[0007] Preferably, a lead screw frame is fixedly installed on the other side of the positioning frame, a reciprocating lead screw is rotatably installed on the lead screw frame, a reciprocating slider is connected to the reciprocating lead screw, a guide frame is fixedly installed on the reciprocating slider, and a pinion is fixedly installed at one end of the reciprocating lead screw, and the pinion meshes with the linkage gear.

[0008] Preferably, the lead screw frame is provided with a bearing, and the reciprocating lead screw is rotatably mounted on the lead screw frame via the bearing.

[0009] Preferably, the positioning frame is equipped with bearings, and the circumferential cutting blade and circumferential cutting seat are rotatably mounted on the positioning frame via bearings. The first motor is fixedly mounted on one side of the positioning frame via a motor frame.

[0010] Preferably, the winding mechanism includes a mounting frame fixedly installed in the workbench, a second motor fixedly installed on one side of the mounting frame, a winding shaft fixedly installed at the output end of the second motor, a discharge chute installed between the mounting frames, a heating wire fixedly installed at the upper end of the discharge chute, a cylinder fixedly installed at the bottom of the mounting frame, and a discharge push plate fixedly installed at the output end of the cylinder.

[0011] Preferably, the unloading push plate has a movable hole in the middle position, and the winding shaft passes through the movable hole to pass through the unloading push plate.

[0012] Preferably, the mounting frame is equipped with a bearing, and the take-up shaft is rotatably mounted on the mounting frame via the bearing.

[0013] Preferably, a coupling is installed at the output end of the second motor, the winding shaft is fixedly installed at the output end of the second motor through the coupling, and the unloading push plate is movably installed above the mounting frame by a cylinder.

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

[0015] 1. In this application, driven by a linkage gear, the ring cutter and the ring cutter seat rotate synchronously, thereby removing the excess material from both sides of the nonwoven fabric. The removed waste material is then wound up by a take-up shaft. During the winding process, the linkage gear drives the pinion to rotate. When the pinion rotates, it drives the reciprocating screw to rotate. As the reciprocating screw rotates, the reciprocating slider slides left and right. As the reciprocating slider slides left and right, the guide frame fixed on it also slides left and right synchronously, thereby guiding the waste material to be evenly wound onto the take-up shaft.

[0016] 2. In this application, when the accumulated amount of waste material on the take-up shaft is large, the cylinder can be retracted. During the retraction of the cylinder, the unloading pusher plate pushes the waste clumps wound on the take-up shaft forward, freeing up the take-up shaft section below the guide frame and creating favorable conditions for rewinding. As the winding operation continues, multiple waste clumps will form on the take-up shaft. These waste clumps will separate from the take-up shaft under the pushing action of the unloading pusher plate. The waste material detached from the take-up shaft will roll down the unloading chute into the waste bin. The waste material falling into the waste bin is tightly wound with small gaps between the waste materials, allowing the waste bin to hold more waste material and reducing the frequency of waste bin cleaning for the user.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1: As Figure 1 and Figure 2As shown, this utility model provides a technical solution for a spherical nonwoven fabric edge cutting device. The bottom of the workbench 1 is provided with a waste bin 2, and guide rollers 3 are installed at both ends of the workbench 1. Nonwoven fabric 4 is provided between the guide rollers 3. Edge cutting components 5 are installed on both sides of the workbench 1, and a winding mechanism 6 is provided inside the workbench 1.

[0024] Specifically, the guide roller 3 can guide the nonwoven fabric 4 through the worktable 1. When the nonwoven fabric 4 passes through the worktable 1, the edge cutting component 5 can cut off the excess parts on both sides of the nonwoven fabric 4. The edge cutting component 5 works in conjunction with the winding mechanism 6 to wind the waste material fed into the waste bin 2 into a waste clump, so that the waste bin 2 can hold more waste material and reduce the frequency of users cleaning the waste bin 2.

[0025] Example 2: Figure 2 and Figure 3 As shown, the trimming assembly 5 includes a positioning frame 501 fixedly mounted on the worktable 1. A ring cutter 505 and a ring cutter seat 506 are rotatably mounted on the positioning frame 501. A linkage gear 504 is fixedly mounted on one side of both the ring cutter 505 and the ring cutter seat 506, and the two sets of linkage gears 504 mesh together. A motor frame 503 is fixedly mounted on one side of the positioning frame 501. A first motor 502 is fixedly mounted on the motor frame 503, and the output end of the first motor 502 is fixedly mounted in the linkage gear 504. At the intermediate position, a lead screw frame 508 is fixedly installed on the other side of the positioning frame 501. A reciprocating lead screw 509 is rotatably installed on the lead screw frame 508. A reciprocating slider 511 is connected to the reciprocating lead screw 509. A guide frame 510 is fixedly installed on the reciprocating slider 511. A pinion 507 is fixedly installed at one end of the reciprocating lead screw 509, and the pinion 507 meshes with the linkage gear 504. A bearing is provided on the lead screw frame 508, and the reciprocating lead screw 509 is rotatably installed on the lead screw frame 508 through the bearing.

[0026] Specifically, when the nonwoven fabric 4 passes through the gap between the ring cutter 505 and the ring cutter seat 506, the first motor 502 can be activated. Under the action of the linkage gear 504, the ring cutter 505 and the ring cutter seat 506 will rotate synchronously, thereby cutting off the excess part on both sides of the nonwoven fabric 4. The cut-off waste material will be wound up by the winding shaft 607.

[0027] During the winding process, the linkage gear 504 drives the pinion 507 to rotate. When the pinion 507 rotates, it drives the reciprocating lead screw 509 to rotate. When the reciprocating lead screw 509 rotates, the reciprocating slider 511 slides left and right. When the reciprocating slider 511 slides left and right, the guide frame 510 fixed on it also slides left and right, thereby guiding the waste material to be evenly wound on the winding shaft 607.

[0028] Example 3: Figure 2 and Figure 4As shown, the winding mechanism 6 includes a mounting frame 604 fixedly installed in the workbench 1. A second motor 601 is fixedly installed on one side of the mounting frame 604. A winding shaft 607 is fixedly installed at the output end of the second motor 601. A discharge chute 605 is installed between the mounting frames 604. A heating wire 606 is fixedly installed at the upper end of the discharge chute 605. A cylinder 603 is fixedly installed at the bottom of the mounting frame 604. A discharge push plate 602 is fixedly installed at the output end of the cylinder 603. A movable hole is opened in the middle of the discharge push plate 602. The winding shaft 607 passes through the movable hole and passes through the discharge push plate 602.

[0029] Specifically, after starting the second motor 601, it drives the take-up shaft 607 to rotate, thereby winding the cut-off waste material onto the take-up shaft 607. When there is a large amount of waste material wound on the take-up shaft 607, the cylinder 603 can be retracted. When the cylinder 603 is retracted, the unloading push plate 602 will push the clump of waste material wound on the take-up shaft 607 forward, freeing up part of the take-up shaft 607 below the guide frame 510 for rewinding.

[0030] As the winding process continues, multiple clumps of waste material will be wound onto the winding shaft 607. These clumps will then detach from the winding shaft 607 under the pushing action of the unloading pusher plate 602. When the clumps detach from the winding shaft 607, the heating wire 606 will melt the connecting parts between the clumps, causing the detached waste material to roll down the unloading chute 605 into the waste bin 2.

[0031] The waste falling into waste bin 2 is tightly tangled together with small gaps between the waste pieces, so waste bin 2 can hold more waste, thereby reducing the frequency of users cleaning waste bin 2.

[0032] Working principle: During use, the guide roller 3 guides the nonwoven fabric 4 through the worktable 1. The nonwoven fabric 4 passing through the worktable 1 will pass through the gap between the ring cutter 505 and the ring cutter seat 506. When the nonwoven fabric 4 passes through the gap between the ring cutter 505 and the ring cutter seat 506, the first motor 502 can be started. Under the action of the linkage gear 504, the ring cutter 505 and the ring cutter seat 506 will rotate synchronously, thereby cutting off the excess part on both sides of the nonwoven fabric 4. The cut-off waste material will be wound up by the take-up shaft 607. During the winding process, the linkage gear 504 will drive the pinion 507 to rotate. When the pinion 507 rotates, it will drive the reciprocating screw 509 to rotate. When the reciprocating screw 509 rotates, the reciprocating slider 511 will slide left and right. When the reciprocating slider 511 slides left and right, the guide frame 510 fixed on it will also slide left and right, thereby guiding the waste material to be evenly wound on the take-up shaft 607. The cut-off waste material passes through the holes in the guide frame 510 and is fixed onto the take-up shaft 607. After the second motor 601 is started, it drives the take-up shaft 607 to rotate, thereby winding the cut-off waste material onto the take-up shaft 607. When there is a large amount of waste material on the take-up shaft 607, the cylinder 603 can be retracted. When the cylinder 603 is retracted, the unloading push plate 602 pushes the clump of waste material wound on the take-up shaft 607 forward, freeing up the portion of the take-up shaft 607 below the guide frame 510 for easy rewinding. As the winding action proceeds, multiple strands of waste material will be wound onto the winding shaft 607. Under the pushing action of the unloading push plate 602, the waste material will detach from the winding shaft 607. When the waste material detaches from the winding shaft 607, the heating wire 606 will melt the connecting parts between the waste material clumps, causing the waste material that has detached from the winding shaft 607 to roll down along the unloading groove 605 into the waste bin 2. The waste material falling into the waste bin 2 is tightly wrapped together, with small gaps between the waste materials. The waste bin 2 can hold more waste material, reducing the frequency of cleaning the waste bin 2 by the user.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
