Description

Technical Field

[0001] The utility model relates to the technical field of non-woven fabric cutting, and more particularly to a non-woven fabric cutting device. Background Art

[0002] Non-woven fabrics are moisture-proof, breathable, flexible, lightweight, non-combustible, easily decomposable, non-toxic and non-irritating, colorful, inexpensive, and recyclable. Non-woven fabrics are widely used in all aspects of life and often need to be cut to meet different usage needs.

[0003] The existing non-woven fabric cutting device usually installs a roll of non-woven fabric on a feeding mechanism, and the non-woven fabric is pulled out of the feeding mechanism and cut by the cutting device. After the cutting device cuts a roll of non-woven fabric, it is usually necessary to stop the machine to disassemble the reel in the cut non-woven fabric roll and install a new non-woven fabric roll. In this process, a lot of time will be wasted, which affects the production efficiency of the non-woven fabric cutting device. In view of this, we propose a non-woven fabric cutting device. Utility Model Content

[0004] The purpose of the utility model is to overcome the deficiencies of the prior art, meet practical needs, and provide a non-woven fabric cutting device to solve the technical problem that the current non-woven fabric cutting device takes a long time to replace the non-woven fabric roll material, which affects production efficiency.

[0005] In order to solve the above technical problems, the present utility model provides the following technical solutions: a non-woven fabric cutting device, comprising a cutting machine body, and also comprising a feeding mechanism provided at the feeding end of the cutting machine body;

[0006] The cam is fixedly mounted on the bottom of the L-shaped support frame, and the cam is fixedly mounted on the bottom of the L-shaped support frame by a mounting plate. The other side of the top of the L-shaped support frame is provided with a rotating disk, and the rotating disk is fixedly connected to the side opposite to the L-shaped support frame by a long shaft. One end of the long shaft passes through the top of the L-shaped support frame and is transmitted to the output end of the motor through a gear set, and the other side of the rotating disk is rotatably connected to a plurality of mounting sleeves at equal intervals through mounting bearings. A two-way screw rod is provided in the mounting sleeve, and the middle of the two-way screw rod is rotatably connected to the inner wall of the middle of the mounting sleeve by a mounting ring. Both ends of the two-way screw rod are threadedly provided with a movable sleeve, and both ends of the movable sleeve are fixedly connected to a slider, and a slide groove is provided relative to the position of the slider, and the top of the slider passes through the slide groove and is movably connected to a pressure rod.

[0007] Preferably, connection cavities are formed at the tops of the opposite ends of the sliders located on the two moving sleeves, and one end of the pressure rod extends into the connection cavity and is rotatably connected to the inner walls on both sides of the connection cavity through a rotating shaft.

[0008] Preferably, the inner wall of the bottom of the connection cavity and the inner wall of the closed end of the connection cavity intersect at a 90-degree angle.

[0009] Preferably, positioning blocks are fixedly connected to the opposite sides of the pressure rods at both ends of the bidirectional lead screw, and the bottoms of the positioning blocks extend into the sliding grooves.

[0010] Preferably, the positioning blocks at both ends of the bidirectional lead screw are in an arc-shaped structure that gradually bends and depresses from the slider to the top of the pressure rod.

[0011] Preferably, one end of the bidirectional lead screw extends to the outside of the installation sleeve and is fixedly connected to a handwheel.

[0012] Preferably, the diameter of the handwheel is not greater than the diameter of the installation sleeve.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] 1. For the feeding mechanism provided by the present utility model, after one non-woven fabric roll material finishes feeding, the output end of the motor drives the rotating disk through the gear set and the long shaft, transfers the new non-woven fabric roll material to the appropriate feeding position for feeding. During the process of cutting the new non-woven fabric roll material, rotate the handwheel, fold the pressure rod into the sliding groove, remove the reel, thread the non-woven fabric roll material from one end of the installation sleeve into the space between the pressure rods at both ends of the bidirectional lead screw, turn the pressure rod from the sliding groove to the vertical position, rotate the bidirectional lead screw, and the bidirectional lead screw drives the two sliders to move towards each other along the sliding groove through the two moving sleeves. The sliders drive the pressure rods to clamp the two ends of the non-woven fabric roll material oppositely, and fix the non-woven fabric roll material in the middle on the installation sleeve, reducing the downtime of the cutting machine body caused by the loading of the non-woven fabric roll material and improving production efficiency.

[0015] 2. The positioning blocks of the present utility model are in an arc-shaped structure that gradually bends and depresses from the slider to the top of the pressure rod. During the process of the pressure rod driving the positioning blocks to clamp the non-woven fabric roll material, the positioning blocks can support the top and bottom inner walls of both ends of the reel of the non-woven fabric roll material, so that the reel and the installation sleeve rotate coaxially, ensuring uniform feeding, and preventing the situation that the non-woven fabric roll material is prone to jerks during the rotation and feeding process and the feeding is uneven because the diameter of the reel of the non-woven fabric roll material is large and it does not rotate coaxially with the installation sleeve.

[0023] As Figures 1 to 5 shown, a non-woven fabric cutting device related to the present utility model includes a cutting machine body 1 and a feeding mechanism 2; in this embodiment, the cutting machine body 1 is a device existing on the market for cutting non-woven fabrics.

[0024] As Figures 1 to 5 shown, the feeding mechanism 2 is arranged at the feeding end of the cutting machine body 1.

[0025] Specifically, as Figures 1 to 5As shown in the figure, the feeding mechanism 2 includes an L-shaped support frame 201 and a motor 202. One end of the bottom of the L-shaped support frame 201 is fixedly connected to one side of the feeding end of the cutting machine body 1. The motor 202 is fixedly installed on one side of the bottom of the L-shaped support frame 201 through a mounting plate. On the other side of the top of the L-shaped support frame 201, there is a rotating disk 203. A long shaft 204 is fixedly connected to the opposite side of the rotating disk 203 and the L-shaped support frame 201. One end of the long shaft 204 passes through the top of the L-shaped support frame 201 and is driven by a gear set with the output end of the motor 202. On the other side of the rotating disk 203, a number of mounting sleeves 205 are rotatably connected at equal intervals through mounting bearings. A bidirectional lead screw 206 is arranged inside the mounting sleeve 205. The middle of the bidirectional lead screw 206 is rotationally connected to the inner wall of the middle part of the mounting sleeve 205 through a mounting ring. Moving sleeves 207 are threadedly sleeved at both ends of the bidirectional lead screw 206. Sliders 208 are fixedly connected to both ends of the moving sleeve 207. Chutes 2051 are provided at the positions of the mounting sleeve 205 relative to the sliders 208. The top of the slider 208 passes through the chute 2051 and is movably connected to a pressure rod 209. When installing the non-woven fabric roll material, the pressure rod 209 is folded into the chute 2051. The non-woven fabric roll material is inserted into the pressure rods 209 at both ends of the bidirectional lead screw 206 from one end of the mounting sleeve 205. The pressure rod 209 is flipped vertically from the chute 2051. The bidirectional lead screw 206 is rotated. The bidirectional lead screw 206 drives the two sliders 208 to move towards each other along the chute 2051 through the two moving sleeves 207. The slider 208 drives the pressure rod 209 to clamp both ends of the non-woven fabric roll material towards each other, and the non-woven fabric roll material is centered and fixed on the mounting sleeve 205. When the cutting machine body 1 cuts, the cutting machine body 1 continuously extracts the non-woven fabric from the non-woven fabric roll material, driving the non-woven fabric roll material and the mounting sleeve 205 to rotate and unwind on the rotating disk 203. After one non-woven fabric roll material finishes unwinding, the motor 202 is driven by an external control mechanism. The output end of the motor 202 drives the rotating disk 203 to rotate on the L-shaped support frame 201 through the gear set and the long shaft 204, and the new non-woven fabric roll material is transferred to a suitable feeding position. During the process of the cutting machine body 1 cutting the new non-woven fabric roll material, the non-woven fabric roll material that has finished unwinding can be loaded, which can greatly reduce the time of the cutting machine body 1 caused by loading the non-woven fabric roll material and improve the production efficiency.

[0026] Further, as Figures 3 to 5As shown in the figure, connection cavities 2081 are provided at the top of the opposite ends of the sliders 208 located on two moving sleeves 207. One end of the pressure rod 209 extends into the connection cavity 2081 and is rotatably connected to the inner walls on both sides of the connection cavity 2071 through a rotating shaft. The inner wall of the bottom of the connection cavity 2081 and the inner wall of the closed end of the connection cavity 2081 intersect at a 90-degree angle. One end of the pressure rod 209 rotates within the connection cavity 2081 with a 90-degree angle. When clamping both ends of the non-woven fabric roll material, the inner wall of the closed end of the connection cavity 2081 can provide lateral support for the pressure rod 209. When disassembling the non-woven fabric roll material, the inner wall of the bottom of the connection cavity 2081 can provide vertical support for the pressure rod 209.

[0027] Furthermore, as Figures 3 to 5 shown in the figure, positioning blocks 210 are fixedly connected to the opposite sides of the pressure rods 209 at both ends of the bidirectional lead screw 206. The bottom of the positioning blocks 210 extends into the chute 2051. The positioning blocks 210 at both ends of the bidirectional lead screw 206 are in an arc shape that gradually bends and depresses from the slider 208 towards the top of the pressure rod 209. Since the diameter of the drum of the non-woven fabric roll material may not be perfectly adapted to the installation sleeve 205, when the diameter of the drum of the non-woven fabric roll material is larger, due to the weight of the non-woven fabric roll material itself, the inner wall of the top of the drum of the non-woven fabric roll material is in contact with the outer wall of the top of the installation sleeve 205, resulting in the drum and the installation sleeve 205 not being coaxial when rotating. During the process of rotating and feeding the non-woven fabric roll material, it is easy to experience jerks, leading to uneven feeding. During the process of the pressure rod 209 driving the positioning block 210 to clamp the non-woven fabric roll material, the arc shape of the positioning block 210 that gradually bends and depresses from the slider 208 towards the top of the pressure rod 209 can support the inner walls of the top and bottom of both ends of the drum of the non-woven fabric roll material, thereby keeping the drum and the installation sleeve 205 rotating coaxially and ensuring uniform feeding.

[0028] Even further, as Figures 1 to 3 shown in the figure, one end of the bidirectional lead screw 206 extends to the outside of the installation sleeve 205 and is fixedly connected to a handwheel 211. The diameter of the handwheel 211 is not greater than the diameter of the installation sleeve 205. It is convenient to rotate the bidirectional lead screw 206 through the handwheel 211, and the diameter of the handwheel 211 not being greater than the diameter of the installation sleeve 205 is convenient for the installation of the non-woven fabric roll material.

[0029] Working principle: This embodiment provides a non-woven fabric cutting device. When in use, press the pressure rod 209 by hand, so that the pressure rod 209 rotates in the connection cavity 2071 and folds into the chute 2051. Thread the non-woven fabric roll through one end of the installation sleeve 205 to between the pressure rods 209 at both ends of the bidirectional lead screw 206. Flip the pressure rod 209 vertically from the chute 2051. Rotate the bidirectional lead screw 206 by turning the handwheel 211. The bidirectional lead screw 206 drives two sliders 208 to move towards each other along the chute 2051 through two moving sleeves 207. The slider 208 drives the pressure rod 209 and the positioning blocks 210 on the pressure rod 209 to clamp the two ends of the non-woven fabric roll towards each other. The positioning blocks 210 support the top and bottom inner walls of the two ends of the drum of the non-woven fabric roll, so that the drum and the installation sleeve 205 remain coaxial, and the non-woven fabric roll is centered and fixed on the installation sleeve 205. When the cutting machine body 1 cuts, the cutting machine body 1 continuously extracts non-woven fabric from the non-woven fabric roll, driving the non-woven fabric roll and the installation sleeve 205 to rotate and feed materials on the rotating disk 203. After one non-woven fabric roll finishes feeding, drive the motor 202 through an external control mechanism. The output end of the motor 202 drives the rotating disk 203 to rotate on the L-shaped support frame 201 through a gear set and a long shaft 204, and transfers a new non-woven fabric roll to a suitable feeding position. During the process of the cutting machine body 1 cutting the new non-woven fabric roll, the non-woven fabric roll after the feeding is finished can be loaded.

Those of ordinary skill in the art can easily understand the spirit of this utility model according to the above embodiments and make different extensions and changes. However, as long as they do not depart from the spirit of this utility model, they are within the protection scope of this utility model.
