Description

Technical Field

[0001] This utility model relates to the field of nonwoven fabric processing technology, and in particular to a cutting device for nonwoven fabric processing. Background Technology

[0002] An edge-trimming device in nonwoven fabric processing is a piece of equipment used to ensure that the edges of nonwoven fabrics are neat and reach the required width. Nonwoven fabric is a material widely used in medical, agricultural, and household fields, so edge-trimming devices play an important role in nonwoven fabric production. Traditionally, slitting machines are used for edge trimming of nonwoven fabrics.

[0003] When using a slitting machine to trim the edges of non-woven fabric, the non-woven fabric is first pulled out from the unwinding rod, passed through the guide rod of the slitting machine, then through the guide roller in the center, and finally mounted on the take-up rod on the other side. Then, the blades on both sides of the blade holder are operated to make the blades fit precisely for trimming. The position of the blade holder is then adjusted so that the blades are in contact with the surface of the non-woven fabric. Finally, the control box is operated to set the parameters of the slitting machine, causing the drive motor inside the equipment to run. The unwinding rod and the take-up rod will rotate synchronously, and the blades will contact the non-woven fabric to cut and trim the edges. However, in actual use, it was found that because the non-woven fabric is stretched too much during trimming, it will become loose and wobbly during the trimming process, which will affect the trimming effect and reduce the quality of the finished product. Utility Model Content

[0004] The technical problem this invention aims to solve is that when nonwoven fabric is stretched too much during edge trimming, it becomes loose and wobbly, which affects the trimming effect and reduces the quality of the finished product.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a non-woven fabric processing edge trimming device, including a slitting machine, wherein a unwinding rod and a winding rod are respectively installed on both sides of the surface of the slitting machine, a guide rod is provided on the side of the surface of the slitting machine near the unwinding rod, a drive motor is installed on the inner wall of the slitting machine, a blade holder is provided on the surface of the slitting machine, wherein two blades are installed on the surface of the blade holder, a controller is installed on one side of the surface of the slitting machine, and an adjustment device is provided on the surface of the slitting machine, wherein the adjustment device strengthens the tension of the non-woven fabric by means of a positioning roller and an adjusting roller.

[0006] The effect achieved by the above components is as follows: When using a slitting machine to trim the edges of nonwoven fabric, firstly, the nonwoven fabric on the unwinding rod is pulled out and passed through the guide rod of the slitting machine, then through the adjusting device and the guide roller at the center of the slitting machine, and finally assembled on the take-up rod on the other side. Then, the blades on both sides of the blade holder are operated so that the blades are just right for trimming. Next, the position of the blade holder is adjusted so that the blades are in contact with the surface of the nonwoven fabric. Finally, the controller is operated to set the parameters of the slitting machine so that the unwinding rod and the take-up rod will rotate synchronously, and at the same time, the blades will contact the nonwoven fabric to cut and perform the trimming operation.

[0007] Preferably, the adjusting device includes two rotating plates, with two mounting rods rotatably connected to the sides of the two rotating plates that are close to each other. Positioning rollers and adjusting rollers are rotatably mounted on the arc surfaces of the two mounting rods, respectively. Mounting plates are rotatably connected to both ends of the mounting rods assembling the positioning rollers. An adjusting shaft is rotatably connected to the arc surface of the mounting rods on the adjusting rollers. The mounting plates are connected to the inner wall of the slitting machine. Two adjusting belts are fixedly connected to the arc surface of the adjusting shaft, with a connecting rod mounted at the other end of each of the two adjusting belts. Mounting plates are rotatably connected to both ends of the connecting rod, and the mounting plates are fixedly mounted to the surface of the slitting machine. A servo motor is mounted on the surface of one of the mounting plates, and the output end of the servo motor is connected to one end of the connecting rod via a coupling.

[0008] The effect achieved by the above components is that when using a slitting machine to trim the edges of non-woven fabric, the non-woven fabric can be kept in a tighter state and is less likely to become loose and wobbly, which facilitates the trimming of the blades, improves the quality of the finished product, and also improves the use effect and functionality of the slitting machine.

[0009] Preferably, reinforcing sleeves are installed on the arc surfaces of both the positioning roller and the adjusting roller, wherein the reinforcing sleeves improve their performance.

[0010] The effect achieved by the above components is that, through the reinforcing sleeve made of rubber, a "flexible buffer layer" is formed when the nonwoven fabric slides on the arc surface of the positioning roller and the adjusting roller, so as to avoid damage to the nonwoven fabric due to hard contact.

[0011] Preferably, the inner walls of the slitting machine are fixedly connected to two sides of an adjusting frame, wherein the adjusting frame is slidably connected to the inner wall of the mounting plate, and the inner wall of the adjusting frame is rotatably connected to a threaded rod, the threaded rod being threadedly connected to the surface of the mounting plate.

[0012] The effect achieved by the above components is as follows: when adjusting the position of the mounting plate and the corresponding components, the threaded rods on the two sides of the adjustment frame can be rotated. The rotation of the threaded rods will cause the mounting plate to slide, thereby increasing the degree of distortion of the fabric surface when the adjusting roller bends and tightens the nonwoven fabric, and better ensuring the tight edge cutting effect of the nonwoven fabric.

[0013] Preferably, a positioning ring is threaded onto one side surface of the threaded rod, wherein the positioning ring improves the positional stability of the mounting plate.

[0014] The effect achieved by the above components is as follows: by setting the positioning ring, after adjusting the position of the mounting plate by rotating the threaded rod, the positioning ring can be rotated to contact the mounting plate, preventing abnormal displacement of the mounting plate caused by the rotation of the threaded rod.

[0015] Preferably, the adjusting device further includes two take-up reels fixedly connected to the arc surface of the connecting rod, and the inner walls of the two take-up reels are respectively connected and fixed to the ports of the two adjusting belts.

[0016] The effect achieved by the above components is that, through the setting of the take-up reel, the adjustment belt can be kept in a stable coil during the winding and unwinding process, and is not easy to loosen, thereby pulling the adjustment shaft more stably and accurately.

[0017] Preferably, a mounting frame is mounted on the surface of both mounting plates, wherein brush rollers are rotatably connected to the two arc surfaces of the mounting frame.

[0018] The effect achieved by the above components is that, through the installation of the mounting frame and the brush rollers, the brush rollers on both sides will rub and rotate with the nonwoven fabric during the stretching process, thereby cleaning up impurities such as lint on the fabric surface and facilitating subsequent use.

[0019] Preferably, the inner walls of the sliding grooves on both sides of the adjusting shaft are slidably connected to a reinforcing rod, and two springs are fixedly connected to the surface of the reinforcing rod away from the adjusting roller, wherein the other end of the spring is connected and fixed to the inner wall of the sliding groove of the adjusting shaft.

[0020] The effect achieved by the above components is that when the positioning rod abuts against one side surface of the nonwoven fabric, the reinforcing rod will slide in the inner wall of the adjusting shaft under the elastic force of the spring until it comes into contact with the nonwoven fabric, thereby making the nonwoven fabric better fit with the adjusting roller.

[0021] The beneficial effects of this utility model are:

[0022] When using a slitting machine to trim the edges of nonwoven fabric, this invention can better maintain the nonwoven fabric in a taut state, making it less prone to loosening and shaking.

Detailed Implementation

[0031] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0032] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0033] Example 1, Figure 1 and Figure 2The shown nonwoven fabric processing edge trimming device includes a slitting machine 1. A unwinding rod 2 and a winding rod 4 are respectively installed on both sides of the surface of the slitting machine 1. A guide rod 7 is provided on the side of the surface of the slitting machine 1 near the unwinding rod 2. A drive motor 6 is installed on the inner wall of the slitting machine 1. A blade holder 8 is provided on the surface of the slitting machine 1, wherein two blades 9 are installed on the surface of the blade holder 8. A controller 5 is installed on one side of the surface of the slitting machine 1. An adjustment device 3 is provided on the surface of the slitting machine 1, wherein the adjustment device 3 strengthens the tension of the nonwoven fabric by means of a positioning roller 33 and an adjusting roller 34.

[0034] Figure 1 - Figure 4 As shown, when using the slitting machine 1 to trim the edges of nonwoven fabric, firstly, the nonwoven fabric on the unwinding rod 2 is pulled out, passes through the guide rod 7 of the slitting machine 1, then around the adjusting roller 34, and passes under the positioning roller 33 to form an "8"-shaped winding configuration. It then passes through the guide roller at the center of the slitting machine 1 and is finally mounted on the take-up rod 4 on the other side. Next, the blades 9 on both sides of the blade holder 8 are operated to ensure they are properly fitted for trimming. The position of the blade holder 8 is then adjusted so that the blades 9 are in contact with the surface of the nonwoven fabric. Finally, the control box is operated to set the parameters of the slitting machine 1, causing the unwinding rod 2 and the take-up rod 4 to rotate synchronously. Simultaneously, the blades 9 contact and cut the nonwoven fabric to perform the trimming. During operation, when the nonwoven fabric becomes loose and wobbly, the servo motor 310 on the assembly plate 39 is activated. The servo motor 310 drives the connecting rod 38 to rotate, thereby winding up the two adjusting belts 37. At this time, the adjusting shaft 36 is pulled, which in turn pulls the rotating plate 31. The rotating plate 31 rotates around the mounting rod 32 on the positioning roller 33, causing the adjusting roller 34 to pull and squeeze the nonwoven fabric, forming a taut state. When using the slitting machine 1 to trim the edges of the nonwoven fabric, the nonwoven fabric can be kept in a tighter state, and it is less likely to become loose and wobbly. This facilitates the trimming of the blade 9, improves the quality of the finished product, and also improves the use effect and functionality of the slitting machine 1.

[0035] Figure 2 and Figure 4The positioning roller 33 and adjusting roller 34 shown are both equipped with reinforcing sleeves 312. The reinforcing sleeves 312 improve their performance. The rubber reinforcing sleeves 312 form a "flexible buffer layer" when the nonwoven fabric slides on the arc surfaces of the positioning roller 33 and adjusting roller 34, preventing damage to the nonwoven fabric due to hard contact. Adjusting frames 313 are fixedly connected to both sides of the inner wall of the slitting machine 1. The adjusting frames 313 are slidably connected to the inner wall of the mounting plate 35, and the inner wall of the adjusting frames 313 is rotatably connected to a threaded rod 314. The threaded rod 314 is threadedly connected to the surface of the mounting plate 35. When adjusting the position of the mounting plate 35 and the corresponding components, the threaded rods 314 on both sides of the adjusting frames 313 can be rotated. The rotation of the threaded rods 314 will cause the mounting plate 35 to slide, thereby further increasing the distortion of the fabric surface when the adjusting roller 34 bends and tightens the nonwoven fabric, and better ensuring the tight edge cutting effect of the nonwoven fabric.

[0036] Figure 4 and Figure 5 A positioning ring 315 is threaded onto one side surface of the threaded rod 314. The positioning ring 315 improves the positional stability of the mounting plate 35. By setting the positioning ring 315, after adjusting the position of the mounting plate 35 by rotating the threaded rod 314, the positioning ring 315 can be rotated to contact the mounting plate 35, preventing abnormal displacement of the mounting plate 35 caused by the rotation of the threaded rod 314. The adjustment device 3 also includes two take-up reels 311 fixedly connected to the arc surface of the connecting rod 38. The inner walls of the two take-up reels 311 are respectively connected and fixed to the ports of the two adjustment belts 37. By setting the take-up reels 311, the adjustment belts 37 can ensure a stable coil during the winding and unwinding process, and are not prone to loosening, thereby pulling the adjustment shaft 36 more stably and accurately.

[0037] Figure 3 and Figure 6 The two mounting plates 35 shown are mounted on a common mounting frame 316. Brush rollers 317 are rotatably connected to the two arc surfaces of the mounting frame 316. With the mounting frame 316 and the brush rollers 317, the brush rollers 317 on both sides will rotate and rub against the nonwoven fabric during the stretching process, thereby cleaning the lint and other impurities on the fabric surface, which is convenient for subsequent use. The inner walls of the sliding grooves on both sides of the adjusting shaft 36 are slidably connected to a reinforcing rod 318. Two springs 319 are fixedly connected to the surface of the reinforcing rod 318 away from the adjusting roller 34. The other end of the spring 319 is fixedly connected to the inner wall of the sliding groove of the adjusting shaft 36. When the positioning rod abuts against one side of the nonwoven fabric, the reinforcing rod 318 will slide in the inner wall of the adjusting shaft 36 under the elastic force of the spring 319 until it comes into contact with the nonwoven fabric, so that the nonwoven fabric can better fit with the adjusting roller 34.

[0038] Working Principle: When using slitting machine 1 to trim the edges of nonwoven fabric, firstly, the nonwoven fabric on the unwinding rod 2 is pulled out, passes through the guide rod 7 on slitting machine 1, then around the adjusting roller 34, and passes under the positioning roller 33, forming an "8" shape. It then passes through the guide roller at the center of slitting machine 1 and is finally mounted on the take-up rod 4 on the other side. Next, the blades 9 on both sides of the blade holder 8 are operated to ensure they are properly fitted for trimming. The position of the blade holder 8 is then adjusted so that the blades 9 are in contact with the surface of the nonwoven fabric. Finally, the control box is operated to set the parameters of slitting machine 1, causing the drive motor 6 on the inner wall of the equipment to run. This causes the unwinding rod 2 and take-up rod 4 to rotate synchronously, and the blades 9 to contact and cut the nonwoven fabric for trimming. When the nonwoven fabric becomes loose and wobbly, the servo motor 310 (model ISMC) on the assembly plate 39 is activated. In the SRM3 series, the servo motor 310 drives the connecting rod 38 to rotate, thereby winding the two adjusting belts 37. At this time, the adjusting shaft 36 is pulled, which in turn pulls the rotating plate 31. The rotating plate 31 rotates around the mounting rod 32 on the positioning roller 33, causing the adjusting roller 34 to pull and squeeze the nonwoven fabric, forming a taut state. When using the slitting machine 1 to trim the edges of the nonwoven fabric, the nonwoven fabric can be kept in a tighter state, and it is not easy for it to become loose and shake. This facilitates the trimming of the blade 9, improves the quality of the finished product, and also improves the use effect and functionality of the slitting machine 1.

[0039] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
