[0002] Nonwoven fabrics are widely used in many fields, and using a fabric cutting machine to cut them is of great significance. First, the fabric cutting machine can cut precisely to ensure that the nonwoven fabric is cut to the required size. For example, in the medical field, such as the production of disposable surgical gowns and masks, accurate dimensions are the key to ensuring product functionality and safety. Second, it can improve cutting efficiency. In large-scale production, manual cutting is slow and prone to fatigue, while fabric cutting machines can operate continuously to meet the needs of a large number of orders. Furthermore, the edges cut by the fabric cutting machine are neat and smooth, with stable quality, which can reduce the defect rate, improve overall production efficiency, and ensure the quality of subsequent processing of nonwoven fabrics and the final product.

[0003] During the nonwoven fabric cutting process, impurities often remain on the surface of the nonwoven fabric. However, existing fabric cutting machines have limitations in removing impurities from the surface of nonwoven fabrics and cannot complete the impurity cleaning work, which in turn affects subsequent processes or product quality to a certain extent.

[0036] To further understand the invention content, features and effects of this utility model, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0037] The structure of this utility model will now be described in detail with reference to the accompanying drawings.

[0038] Please see Figures 1 to 7 The nonwoven fabric cutting machine provided in this embodiment includes a frame 1; a first support frame 2 is installed on the upper side of the frame 1, and a plurality of cutting blades 3 are installed on the first support frame 2; a second support frame 4 is installed on the left side of the frame 1; a meter-counting wheel 5 is installed on the second support frame 4; an impurity removal component is installed on the frame 1, and the impurity removal component is located between the meter-counting wheel 5 and the cutting blades 3; a material receiving component is installed on the side of the frame 1 near the cutting blades 3.

[0039] Furthermore, two symmetrically arranged conveying rollers 6 are installed on the side of the frame 1 near the second support frame 4; a first motor 7 is installed on one side of the frame 1, and the output end of the first motor 7 is fixedly connected to one of the conveying rollers 6.

[0040] Using the above scheme: When non-woven fabric needs to be cut, the operator passes one side of the non-woven fabric through two conveyor rollers 6, through the meter-counting wheel 5, the impurity removal component, and the cutter 3, and finally hangs it on the receiving unit. Then, the output end of the first motor 7 is rotated, which in turn drives the conveyor rollers 6 to rotate, thereby conveying the non-woven fabric. At the same time, the receiving unit is driven to rotate, pulling the non-woven fabric. Through the cooperation of the conveyor rollers 6 and the receiving unit, the non-woven fabric moves. During the movement, the non-woven fabric comes into contact with the meter-counting wheel 5, which measures the length of the non-woven fabric. After passing through the meter-counting wheel 5, the non-woven fabric comes into contact with the impurity removal component, which cleans the impurities on the surface of the non-woven fabric. After passing through the impurity removal component, the cutter 3 cuts the non-woven fabric, and as the receiving unit rotates, the cut non-woven fabric is collected.

[0041] Furthermore, the receiving component includes a first tension roller 8 rotatably connected to the frame 1; the first tension roller 8 is located to the right of the cutter 3, and a second tension roller 9 is provided below the first tension roller 8; the second tension roller 9 is rotatably connected to the frame 1, and a receiving roller 10 is provided below the second tension roller 9, and the receiving roller 10 is rotatably connected to the frame 1.

[0042] Furthermore, a first synchronous pulley 11 is installed at one end of both the second tension roller 9 and the take-up roller 10; a second motor 12 is installed on the frame 1; a second synchronous pulley 13 is installed at the output end of the second motor 12, and a synchronous belt 14 is sleeved on the first synchronous pulley 11 and the second synchronous pulley 13.

[0043] Using the above scheme: In use, after the nonwoven fabric passes through two conveyor rollers 6, it passes through the metering wheel 5 and the impurity removal component in sequence, and then reaches the cutter 3 for cutting. The cut nonwoven fabric then passes through the first tension roller 8 and the second tension roller 9, and is finally hung on the take-up roller 10, which drives the output end of the second motor 12 to rotate, thereby driving the second synchronous wheel 13 on it to rotate. Using the synchronous belt 14, the two first synchronous wheels 11 rotate. When the two first synchronous wheels 11 rotate, they will drive the first tension roller 8 and the take-up roller 10 on them to rotate synchronously. In this way, while the nonwoven fabric is being cut, it is kept flat by the straightening effect of the first tension roller 8 and the second tension roller 9. At the same time, the rotation of the take-up roller 10 allows the cut nonwoven fabric to be rolled up, which is convenient for subsequent storage and transportation.

[0044] Furthermore, the impurity removal assembly includes a connecting roller 15 rotatably connected to the frame 1; the connecting roller 15 is located between the metering wheel 5 and the cutting blade 3, and a plurality of first connecting pipes 16 are connected to the surface of the connecting roller 15; a second connecting pipe 17 is slidably connected inside the first connecting pipe 16, and the first connecting pipe 16 and the second connecting pipe 17 are interconnected; a tension spring 18 is installed between the first connecting pipe 16 and the second connecting pipe 17.

[0045] Furthermore, a fixing block 19 is installed at one end of the second connecting pipe 17; a cleaning plate 20 is installed inside the fixing block 19, and two symmetrical limiting rods 21 are slidably connected on the fixing block 19, with one end of the limiting rod 21 extending into the cleaning plate 20; a second spring 22 is installed between the limiting rod 21 and the fixing block 19.

[0046] Furthermore, a first vent pipe 23 is installed on the side of the frame 1 near the second tension roller 9;

[0047] The lower side of the first vent pipe 23 is connected to a plurality of second vent pipes 24, the second vent pipes 24 are arc-shaped, and one end of the second vent pipe 24 is connected to an air outlet plate 25; one end of the first vent pipe 23 is connected to a flexible hose 26, and the other end of the flexible hose 26 is connected to one end of the connecting roller 15.

[0048] Using the above scheme: In use, multiple cleaning pads 20 are inserted into the fixing block 19 respectively. The cleaning pads 20 push the limiting rod 21 and compress the second spring 22, causing the limiting rod 21 to move to both sides. After the cleaning pads 20 move to the preset position, the compressed second spring 22 pushes the limiting rod 21 to move in the opposite direction to fix the cleaning pads 20. After the pump body is connected to the first vent pipe 23, the gas enters the second vent pipe 24 and the flexible hose 26 through the first vent pipe 23. The gas in the flexible hose 26 enters the connecting roller 15. The gas in the connecting roller 15 pushes the second connecting pipe 17 in the first connecting... The tube 16 slides and extends out, while the second connecting tube 17 pulls the tension spring 18, causing the cleaning plate 20 to move to a preset position. When the cleaning plate 20 reaches the preset position, the gas in the second connecting tube 17 enters the air outlet plate 25. When the nonwoven fabric passes through the conveyor roller 6, the cleaning plate 20 rotates synchronously and contacts the surface of the nonwoven fabric to clean impurities such as dust and debris on the nonwoven fabric. When the nonwoven fabric is cut by the cutter 3 and passes through the second tension roller 9, the gas in the second vent pipe 24 is blown out through the air outlet plate 25 to clean the fine fiber debris or burrs on the surface of the nonwoven fabric.

[0049] It should be noted that: First, a solenoid valve can be installed at the connection between the flexible hose 26 and the connecting roller 15. Therefore, after the cleaning plate 20 moves to the preset position, the solenoid valve closes, and gas will not enter the connecting roller 15. Second, the flexible hose 26 is connected to the connecting roller 15 through a rotary joint. Therefore, when the connecting roller 15 rotates, the flexible hose 26 will not rotate with it. Third, when the cleaning plate 20 needs to be removed, the worker can manually pull the limit rod 21 to remove the cleaning plate 20 from the fixing block 19.

[0050] The working principle of this utility model:

[0051] When nonwoven fabric needs to be cut, multiple cleaning sheets 20 are inserted into the fixing block 19. The cleaning sheets 20 push the limiting rod 21 and compress the second spring 22, causing the limiting rod 21 to move to both sides. After the cleaning sheets 20 move to the preset position, the compressed second spring 22 pushes the limiting rod 21 to move in the opposite direction to fix the cleaning sheets 20. After the pump body is connected to the first vent pipe 23, the gas enters the second vent pipe 24 and the flexible hose 26 through the first vent pipe 23. The gas in the flexible hose 26 enters the connecting roller 15. The gas in the connecting roller 15 pushes the second connecting pipe 17 to slide and extend out of the first connecting pipe 16. At the same time, the second connecting pipe 17 pulls the tension spring 18, causing the cleaning sheets 20 to move to the preset position. When the cleaning sheets 20 reach the preset position, the gas in the second connecting pipe 17 enters the air outlet plate 25. The operator passes one side of the nonwoven fabric through the two conveying rollers 6, through the meter wheel 5, the cleaning sheet 20, and then to the cutting blade 3 for cutting. After cutting... The nonwoven fabric then passes through the first tension roller 8 and the second tension roller 9, and is finally hung on the take-up roller 10. This drives the output end of the second motor 12 to rotate, which in turn drives the second synchronous pulley 13 to rotate. Using the synchronous belt 14, the two first synchronous pulleys 11 rotate. When the two first synchronous pulleys 11 rotate, they drive the first tension roller 8 and the take-up roller 10 to rotate synchronously, respectively. In this way, the nonwoven fabric is cut while being straightened by the first tension roller 8 and the second tension roller 9. The function is to keep it flat. At the same time, the rotation of the receiving roller 10 allows the cut nonwoven fabric to be rolled up, which is convenient for subsequent storage and transportation. When the nonwoven fabric passes through the conveying roller 6, the cleaning plate 20 rotates synchronously and contacts the surface of the nonwoven fabric to clean impurities such as dust and debris. When the nonwoven fabric is cut by the cutter 3 and passes through the second tension roller 9, the gas in the second air pipe 24 is blown out through the air outlet plate 25 to clean the fine fiber debris or burrs on the surface of the nonwoven fabric.
