[0002] Non-woven fabric, also known as non-woven fabric, is made of directional or random fibers. It is called cloth because it has the appearance and certain properties of cloth. Non-woven fabric has the characteristics of moisture-proof, breathable, flexible, lightweight, non-combustible, easy to decompose, non-toxic and non-irritating, rich colors, low price, and recyclable.

[0003] During the production of non-woven fabrics, in order to ensure the neatness of the edges of the non-woven fabrics, edge trimming is required. The existing non-woven fabric trimming device cuts the edges of the non-woven fabrics by a rotating cutting blade when in use. However, the non-woven fabric scraps that fall off after being cut are mostly long strips, which are easily entangled on the rotating shaft on which the cutting blades are installed, causing the non-woven fabric edges to accumulate and squeeze the normally moving non-woven fabrics, affecting the stability of the cutting of the non-woven fabric edges.

DETAILED DESCRIPTION

[0016] The specific implementation of the utility model is further described below in conjunction with the accompanying drawings.

[0017] like Figure 1-3As shown, a trimming device for non-woven fabric processing comprises a bottom box 1, a first bracket 2 is arranged on the bottom box 1, a supporting roller 3 is arranged on the first bracket 2, a second bracket 4 is also arranged on the bottom box 1, a trimming roller 5 and a steering roller 6 are arranged on the second bracket 4, the trimming roller 5 is located above the steering roller 6, and the non-woven fabric 7 passes through the supporting roller 3, the trimming roller 5 and the steering roller 6 in sequence, a trimming shaft 8 is also arranged on the second bracket 4, and trimming blades 9 are respectively arranged at both ends of the outer surface of the trimming shaft 8, a rotating shaft 10 is also arranged on the second bracket 4, and sleeves 11 are respectively arranged at both ends of the outer surface of the rotating shaft 10, a first cutter head 12 is arranged on the outer surface of the sleeve 11, and a first cutter head 12 is arranged on the outer surface of the trimming shaft 8. A groove is provided, and a second cutter head 13 matching the first cutter head 12 is provided inside the groove. Bendable side rods 14 are evenly provided on the outer surface of the sleeve 11. The length of the side rods 14 is greater than the height of the first cutter head 12. A first motor 15 is provided on the outer surface of the second bracket 4. The output end of the first motor 15 is fixedly connected to one end of the trimming shaft 8. The trimming roller 5 and one end of the rotating shaft 10 are provided with mutually meshing gears 16. A support plate 17 is also provided on one side of the second bracket 4. A second motor 18 is provided on the support plate 17. The output end of the second motor 18 is fixedly connected to one end of the trimming roller 5. The rotation direction of the rotating shaft 10 is the same as the rotation direction of the trimming shaft 8.

[0018] The nonwoven fabric 7 moves from the production direction to the direction of the support roller 3. The support roller 3 is used to support the nonwoven fabric 7. After the nonwoven fabric 7 continues to pass through the trimming roller 5 and the steering roller 6, it passes through the subsequent winding roller to be wound up.

[0019] The number of the second cutter heads 13 on the trimming shaft 8 is equal to the gear ratio of the gear 16 on the trimming roller 5 to the gear 16 on the rotating shaft 10. The gear ratio of the gear 16 on the trimming roller 5 to the gear 16 on the rotating shaft 10 is a positive integer, and when the gear ratio is greater than 2, the second cutter heads 13 are evenly arranged on the circumference of the trimming shaft 8. When the rotating shaft 10 rotates one circle, the first cutter heads 12 on the sleeve 11 can mesh with one of the second cutter heads 13 on the trimming roller 5, so as to facilitate the non-woven fabric 7 The edge material is cut off, and at the same time, the shortest distance between the top of the second cutter head 13 and the center point of the trimming roller 5 is not greater than the radius of the trimming roller 5, so as to prevent the non-woven fabric 7 from failing to fit on the outer surface of the trimming roller 5. When the second motor 18 drives the trimming roller 5 to rotate, the trimming roller 5 drives the non-woven fabric 7 to move, thereby reducing the friction between the non-woven fabric 7 and the trimming roller 5. At the same time, through the external engagement between the two gears 16, the rotating shaft 10 and the first cutter head 12 on the rotating shaft 10 are driven to rotate synchronously.

[0020] When the rotating shaft 10 rotates, the side rod 14 on the sleeve 11 of the rotating shaft 10 can connect with the cut edge part of the non-woven fabric 7, and when one end of the side rod 14 contacts the trimming roller 5 through the non-woven fabric 7, the side rod 14 is squeezed and deformed, thereby increasing the friction between the side rod 14 and the edge of the non-woven fabric 7, making it easier for the edge of the non-woven fabric 7 to pass through the sleeve 11 and the trimming roller 5, and easier for the first cutter head 12 on the rotating shaft 10 and the second cutter head 13 on the trimming roller 5 to cut the edge of the non-woven fabric 7. The length of the first cutter head 12 is greater than the width of the waste cut by the non-woven fabric 7 to prevent the edge of the non-woven fabric 7 from being completely cut off. The material of the side rod 14 is rubber.

[0021] Furthermore, a fixing plate 19 is provided on one side of the second bracket 4, and the fixing plate 19 is located in the area directly below the trimming roller 5. A material guide plate 20 is provided at the lower end of the fixing plate 19, and the lower end of the material guide plate 20 is inclined toward the bottom box 1. After the edge material of the non-woven fabric 7 is cut off by the first blade head 12 and the second blade head 13, the edge material of the non-woven fabric 7 slides to the bottom of the bottom box 1 through the inclined material guide plate 20 to prevent the edge material of the non-woven fabric 7 from accumulating directly below the steering roller 6.

[0022] Working principle: When trimming the non-woven fabric 7, the trimming shaft 8 is driven to rotate by the first motor 15, and the trimming shaft 8 drives the trimming blade 9 to rotate. The trimming blade 9 cuts the edge of the non-woven fabric 7 by squeezing with the trimming roller 5. At the same time, the second motor 18 meshes with two gears 16 to make the trimming roller 5 and the rotating shaft 10 rotate at the same time. The side rod 14 on the sleeve 11 sends the cut edge of the non-woven fabric 7 between the rotating shaft 10 and the trimming roller 5, and cuts the edge of the non-woven fabric 7 through the cooperation of the first blade head 12 and the second blade head 13, so that this part of the edge is completely disconnected from the non-woven fabric 7. Through the continuous rotation of the rotating shaft 10, the cut part of the non-woven fabric 7 can be continuously and completely cut off.

[0023] The device can cut the longer edge material cut from the non-woven fabric 7 into shorter lengths, thereby preventing the edge material of the non-woven fabric 7 from being entangled with the trimming roller 5, the steering roller 6 and the rotating shaft 10, thereby preventing the edge material of the non-woven fabric 7 from accumulating and squeezing the normal movement of the non-woven fabric 7, thereby ensuring the cutting quality and product quality of the non-woven fabric 7.

[0024] In the description of the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
