Description

Technical Field

[0001] The utility model relates to the technical field of non-woven fabric processing, and more specifically, it relates to a trimming device for the edges and corners of non-woven fabric processing. Background Technique

[0002] Non-woven fabric, also called non-woven material, non-woven cloth, or non-woven fabric, is made of fibers arranged in a directional or random manner through friction, interlocking, adhesion, or a combination of these methods, with the essence being "non-woven". Non-woven fabric exists in the form of fibers in the cloth, while the woven cloth exists in the form of yarns in the cloth, which is also a main feature that differentiates non-woven fabric from other fabrics. No individual thread ends can be drawn out from non-woven fabric. During the production of non-woven fabric, the edges of the non-woven fabric will appear in irregular shapes. For the convenience of subsequent use, a trimming device is required to perform cutting and trimming operations on the non-woven fabric.

[0003] In the related art, a trimming device for the edges and corners of non-woven fabric processing realizes the purpose of fixing fabrics with different thicknesses through the cooperation of a pressing block and a second spring, realizes the purpose of fixing the fabric to be cut through the cooperation of a rectangular moving frame and a pressing piece, and realizes the convenience for users to measure the cutting length through the cooperation of a scale bar and a cutter, thereby solving the problem of difficult control of the cutting size.

[0004] The above-mentioned existing technical solutions have the following defects: The cutting efficiency of non-woven fabric is relatively low, and when cutting a roll of non-woven fabric, the distance between the two cutting blades on both sides cannot be adjusted to adjust the width of the cut non-woven fabric, and the moving non-woven fabric cannot be limited during transmission, so it is impossible to avoid the situation of the non-woven fabric tilting during transmission, which will cause the non-woven fabric to be cut obliquely, resulting in excessive cutting on one side and incomplete cutting on the other side. Also, the cut non-woven fabric and the cut edge materials cannot be separated and collected. Content of the Utility Model

The other end of the movable shaft 29 is connected with a first driving wheel 31. The first driving wheel 31 is located on one side of the fixed frame 28. One end of the rotating roller 6 passes through the support plate 2 and is connected with a second driving wheel 32. The second driving wheel 32 is located on one side of the support plate 2. The first driving wheel 31 and the second driving wheel 32 are located in the same plane. The same belt 33 is sleeved on the first driving wheel 31 and the second driving wheel 32. The belt 33 is driven by an external motor 34. The external motor 34 used is not shown in the figure.

[0042] By adopting the above technical solution, through the ejector rod 24, the sliding frame 25 and the sliding blade 26, when the non-woven fabric is wound to a certain diameter, the non-woven fabric is cut, which is convenient for replacing the new winding roller for winding operation. Through the baffle 301, the support block 302, the spring 304 and the push plate 305, the roller for winding the cut non-woven fabric is installed and fixed, which is convenient for winding operation. After winding is completed, it is convenient to replace the winding roller. Through the first driving wheel 31, the second driving wheel 32 and the belt 33, the non-woven fabric is kept synchronized during cutting and winding, avoiding the situation of folding and stacking in the middle.

[0043] The working principle of the present utility model is as follows: during use, the staff puts the non-woven fabric to be cut into the placement box 16, pulls out one end of the non-woven fabric from the discharge port 17 on one side of the placement box 16, passes through the bottom of the rotating roller 6, moves to the left side of the operating table 1, then passes through the two guide wheels 11, enters between the rotating roller 6 and the cutting blade 9, and then passes between the support base 22 and the ejector rod 24. The roller for winding the non-woven fabric is placed in the fixed frame 28. By pressing the push plates 305 on both sides of the support block 302, the push plates 305 on both sides squeeze the spring 304, causing the spring 304 to undergo elastic deformation, so that the support block 302 enters the hole on one side of the roller for winding. After the support block 302 enters the roller, the springs 304 on both sides of the support block 302 push the push plates 305, so that the two push plates 305 support the roller, fixing the roller on the support assembly 30, which is convenient for winding the non-woven fabric;

[0044] It is powered by an external power supply and works through the motor 34, driving the bidirectional threaded rod 3 to rotate, driving the two threaded barrels 4 to approach or move away from each other, driving the two adjusting plates 5 to approach or move away from each other, and thus driving the cutting blades 9 on the opposite sides of the adjusting plate 5 to approach or move away from each other. When cutting non-woven fabrics of different widths, the distance between the two cutting blades 9 is adjusted, so as to realize the cutting operation for non-woven fabrics of different widths. After the adjustment is completed, the external motor 34 drives the belt 33 to transmit power, driving the first driving wheel 31 and the second driving wheel 32 to rotate. By the rotation of the first driving wheel 31, the movable shaft 29 is driven to rotate, thus driving the support assembly 30 to rotate and driving the non-woven fabric to be wound. By pulling, the non-woven fabric is tightened, and the non-woven fabric continuously discharges from the discharge port 17 on one side of the placement box 16. Through the limitation of the rotating roller 6 and the guide wheel 11, the non-woven fabric can be kept flat during transmission and the situation of tilting during transmission can be avoided. When the non-woven fabric passes through the cutting blade 9, through the cooperation of the cutting blade 9 and the rotating roller 6, the irregular edges of the non-woven fabric are cut. The cut non-woven fabric continuously winds around the support assembly 30 through the support seat 22. When the first driving wheel 31 rotates, through the belt 33, the second driving wheel 32 is synchronously driven to rotate. By the second driving wheel 32 driving the movable shaft 29 to rotate, the support assembly 30 rotates in the fixed frame 28, and thus the wound non-woven fabric is wound by the winding roller installed on the support assembly 30;

[0045] The cut edges are separated through the separation groove 13 opened on the fixed plate 12. The separated scraps fall through the falling groove 14 and fall into the storage box 21, which is convenient for the staff to handle uniformly. After winding for a period of time and the winding diameter reaches the requirement, the transmission of the belt 33 is stopped. The staff can push the sliding frame 25 to slide on the ejector rod 24, so that the sliding blade 26 slides in the limit groove 27. When the sliding frame 25 moves to the other end of the ejector rod 24, the sliding blade 26 moves to the other side of the limit groove 27, and the non-woven fabric between the support seat 22 and the ejector rod 24 is cut and separated. After separation, the staff removes the wound roller from the support assembly 30, replaces it with a new winding roller, winds the cut end of the non-woven fabric around the new winding roller again, and performs the winding operation again.

[0046] This specific embodiment is only an explanation of the present invention, and it is not a limitation of the present invention. Those skilled in the art can make modifications without creative contributions to this embodiment according to needs after reading this specification, but as long as it is within the scope of the claims of the present invention, it is protected by the patent law.
