Description

Technical Field

[0001] This utility model relates to the field of air pressure control technology for nonwoven fabric slitting machines, and in particular to a multi-point air pressure compensation system for nonwoven fabric slitting machines. Background Technology

[0002] The multi-point air pressure compensation system of the nonwoven fabric slitting machine is an auxiliary system designed to ensure stable air pressure during the nonwoven fabric slitting process. Because nonwoven fabric is thin and light, even small fluctuations in air pressure during slitting can affect its conveying, cutting, and winding processes. The multi-point air pressure compensation system avoids problems such as nonwoven fabric deviation, wrinkles, uneven cutting, and inconsistent winding tightness caused by unstable air pressure, ensuring the smooth progress of the slitting process and improving the quality and efficiency of nonwoven fabric slitting.

[0003] A search revealed Chinese Patent Publication No. CN221988953U, which discloses a nonwoven fabric slitting mechanism. This mechanism includes a frame, unwinding rollers, two pairs of guide roller groups, and a slitting mechanism positioned between the two pairs of guide roller groups. Multiple take-up rollers are rotatably mounted on the frame. Nonwoven fabric is wound around the unwinding rollers, and the ends of the nonwoven fabric pass through the gaps between the guide roller groups until they abut against the slitting mechanism, slitting the nonwoven fabric into multiple strip structures. These strip structures then pass through the gaps between another pair of guide roller groups and are wound onto the take-up rollers. Each strip structure is wound onto a different take-up roller. The multiple take-up rollers are arranged on the frame... The arc-shaped arrangement ensures a consistent distance from the gaps between the guide rollers to each take-up roller. As the take-up rollers rotate, the distance from which the slit nonwoven fabric is wound onto them remains consistent. The consistent rotation speed of multiple take-up rollers results in uniform winding force on the nonwoven fabric, achieving the goal of slitting the nonwoven fabric into multiple strips of defined width. However, during the nonwoven fabric transport process, the guide rollers, after prolonged use, will experience wear, leading to uneven surface roughness. When the nonwoven fabric passes through the worn areas, the frictional force varies, generating lateral forces and causing the nonwoven fabric to shift. Utility Model Content

[0004] To overcome the above deficiencies, this utility model provides a multi-point air pressure compensation system for a nonwoven fabric slitting machine, which aims to improve the problem of wear on the surface of the guide rollers after long-term use, which leads to nonwoven fabric misalignment.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a multi-point air pressure compensation system for a nonwoven fabric slitting machine, comprising a base, an mounting plate fixedly connected to the top rear side of the base, a feeding component fixedly connected to the front left end of the mounting plate, a cutter shaft component rotatably connected to the front side of the mounting plate, a winding component rotatably connected to the front right end of the mounting plate, a correction mechanism provided at the top left end of the base, a detection component provided at the top of the correction mechanism for detecting the conveying path of the nonwoven fabric, a drive component provided at the bottom of the correction mechanism for driving the correction mechanism to run, compensation components provided at the top of the feeding component, the cutter shaft component, and the winding component, and multiple compensation components for compensating the air pressure at various points, and a collection mechanism provided on the inner wall of the base;

[0006] The correction mechanism includes a support block, the bottom of which is fixedly connected to the top left end of the base. A rotating shaft is fixedly connected to the top of the support block. The same U-shaped block is rotatably connected to both the left and right ends of the rotating shaft. An adjustment frame is fixedly connected to the top of the U-shaped block, and an adjustment shaft is rotatably connected to the top of the adjustment frame.

[0007] Through the above technical solution: when the correction mechanism is running, because the support block is fixed on the base, the rotating shaft connects the support block and the U-shaped block, and the adjusting frame rotates around the rotating shaft with the U-shaped block, thereby adjusting the rotating shaft to change the angle, contacting the non-woven fabric and applying lateral force to correct its offset direction, ensuring that the non-woven fabric is conveyed along the correct path.

[0008] As a further description of the above technical solution:

[0009] The collection mechanism includes a debris collection box, the outer wall of which is slidably connected to the inner wall of the base. Positioning blocks are fixedly connected to both the left and right sides of the debris collection box, and each positioning block has a locking groove at its top. Positioning grooves are formed on both the left and right sides of the inner wall of the base. The inner walls of the two positioning grooves are slidably connected to the outer walls of their respective positioning blocks. Locking balls are slidably connected to the inner walls of the two locking grooves, and springs are fixedly connected to the tops of the two locking balls. The outer walls of the two springs are slidably connected to the inner walls of their respective positioning grooves. A movable component is provided on the front side of the debris collection box.

[0010] Through the above technical solution: the debris generated from cutting non-woven fabric falls into the base, and the debris collection box is responsible for collecting it. The debris collection box is inserted along the inner wall of the base, and the positioning block slides along the positioning groove to accurately position the collection box. At this time, the spring pushes the locking ball part to embed into the locking groove, fixing the collection box and preventing it from sliding during the collection process. When it is necessary to clean the debris, the collection box is pulled by the moving component. The moving component is located on the front side of the collection box, providing an easy-to-operate force point, so that the collection box can slide smoothly along the inner wall of the base for easy cleaning of debris.

[0011] As a further description of the above technical solution:

[0012] The detection component includes two support plates. The bottom of the two support plates is fixedly connected to the front and rear ends of the top left side of the base, respectively. The top of both support plates is fixedly connected to the same horizontal plate, and the front and rear ends of the bottom of the horizontal plate are fixedly connected to optical path sensors.

[0013] Through the above technical solution: two support plates are firmly erected on the front and rear ends of the top left side of the base, supporting the horizontal plate. The optical path sensors at the front and rear ends of the bottom of the horizontal plate emit and receive light. When the non-woven fabric conveying path is normal, the optical path is stable. Once the non-woven fabric deviates, it will block and change the optical path. The optical path sensor detects the deviation information and transmits it to the relevant control components to start the correction action.

[0014] As a further description of the above technical solution:

[0015] The drive assembly includes a servo motor, the bottom of which is fixedly connected to the top left end of the base. An eccentric wheel is fixedly connected to the output end of the servo motor. Slide grooves are provided on the left and right sides of the eccentric wheel. A slider is slidably connected to the inner wall of each of the two slide grooves. A connecting rod is fixedly connected to the top of the slider. A limit block is slidably connected to the outer wall of the connecting rod. Fixing frames are fixedly connected to the front and rear sides of the limit block. The bottoms of the two fixing frames are fixedly connected to the top of the base. The top of the connecting rod is fixedly connected to the front bottom of the adjusting frame.

[0016] Through the above technical solution: the servo motor is fixed at the top left end of the base. After the power is turned on, it starts and the output end of the servo motor drives the eccentric wheel to rotate. The sliding grooves on the left and right sides of the eccentric wheel move accordingly. The slider slides in the sliding groove, converting the circular motion of the eccentric wheel into linear motion. The connecting rod connects the slider and the adjusting frame to transmit the motion. The limit block, supported by the fixed frame, restricts the movement trajectory of the connecting rod to ensure its stable operation. The rotation of the eccentric wheel, through the slider and connecting rod, precisely drives the movement of the adjusting frame, thereby realizing the correction operation of the non-woven fabric conveying path.

[0017] As a further description of the above technical solution:

[0018] The multiple compensation components include multiple PLC controllers, the rear of each of the multiple PLC controllers is fixedly connected to the front of the mounting plate, the right side of each of the multiple PLC controllers is fixedly connected to a pressure sensor, and the right side of each of the multiple pressure sensors is fixedly connected to a compensation air pump.

[0019] The above technical solution involves a pressure sensor that monitors the air pressure at the feeding component, cutter shaft component, and winding component in real time. If the air pressure is abnormal, the data is transmitted to the connected PLC controller. The PLC controller analyzes the data through a preset program and sends a command to the compensation air pump. The compensation air pump then operates accordingly to compensate for the air pressure at the corresponding parts, ensuring stable air pressure at each component and guaranteeing the smooth progress of the nonwoven fabric slitting process.

[0020] As a further description of the above technical solution:

[0021] The movable component includes a movable support, the rear of which is fixedly connected to the front of the debris collection box. A movable handle is fixedly connected to the top of the movable support, and casters are fixedly connected to the four corners of the bottom of the debris collection box.

[0022] With the above technical solution: when it is necessary to clean up debris, the operator holds the moving handle. Because the moving bracket is connected to the debris collection box and the casters at the bottom of the box can rotate flexibly, the collection box can be easily moved in any direction, making it convenient to pull it out from the base for cleaning.

[0023] As a further description of the above technical solution:

[0024] The base has support legs fixedly connected to the four corners at the bottom, and tapered feet fixedly connected to the bottom of each support leg, with rubber pads fixedly connected to the bottom of each tapered foot.

[0025] The above technical solution ensures that the base stands stably on the support legs, the tapered feet at the bottom of the support legs increase the stability of contact with the ground, and the rubber pads prevent slipping and reduce shock, thus ensuring the smooth operation of the slitting machine and reducing the impact of vibration on the equipment.

[0026] As a further description of the above technical solution:

[0027] A central controller is fixedly connected to the top left front end of the base. The central controller is electrically connected to the feeding component, the cutter shaft component, the winding component, the optical path sensor, the servo motor, the PLC controller, the air pressure sensor, and the compensation air pump.

[0028] Through the above technical solution: the central controller, as the core of the system, receives data from optical sensors and air pressure sensors in real time. Based on this data, it sends instructions to the feeding component, the cutter shaft component, and the winding component to regulate each stage of nonwoven fabric slitting. At the same time, it controls the servo motor, PLC controller, and compensation air pump to ensure that all components work together and guarantee the accuracy and stability of the slitting process.

[0029] This utility model has the following beneficial effects:

[0030] 1. In this utility model, the nonwoven fabric is first conveyed through a correction mechanism. Its support block is firmly fixed to the left end of the base. The U-shaped block can rotate around the axis. The adjustment shaft guides the nonwoven fabric. The optical path sensor of the detection component monitors the path. Once there is a deviation, the signal is transmitted to the drive component. The servo motor drives the eccentric wheel in the direction of deviation, which drives the adjustment frame and the adjustment shaft to correct the deviation. At the same time, the compensation component works. The air pressure sensor senses the change in air pressure. The PLC controller controls the compensation air pump to ensure stable air pressure and guarantee the slitting quality and equipment operation.

[0031] 2. In this utility model, when the non-woven fabric slitting machine is running, the debris falls into the base. The debris collection box is slidably connected to the inner wall of the base and placed on the base to collect the debris. When inserted into the base, the positioning block slides along the positioning groove for precise installation. The structure composed of the locking ball and the spring fixes the collection box to prevent it from falling out. When cleaning the debris, the moving component plays a role. The moving bracket is fixed on the front side of the collection box. The operator holds the moving handle and uses the universal wheels to easily pull out the collection box, improving the cleaning efficiency. Attached Figure Description

[0039] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0040] Reference Figure 1 , Figure 2 and Figure 3This utility model provides an embodiment of a multi-point air pressure compensation system for a nonwoven fabric slitting machine, comprising a base 1, which serves as an integral support structure and provides an installation base for other components. A mounting plate 4 is fixedly connected to the rear top of the base 1, serving to fix a feeding component 5, a cutter shaft component 6, and a winding component 7. The feeding component 5 is fixedly connected to the front left end of the mounting plate 4, conveying the nonwoven fabric into the slitting process. The cutter shaft component 6 is rotatably connected to the front of the mounting plate 4, performing slitting operations on the nonwoven fabric. The winding component 7 is rotatably connected to the front right end of the mounting plate 4, winding the slitting nonwoven fabric. A correction mechanism 2 is provided at the top left end of the base 1, used to correct... To prevent the nonwoven fabric from shifting during the conveying process, the top of the correction mechanism 2 is equipped with a detection component 8. This component 8 detects whether the conveying path of the nonwoven fabric has shifted. The detection component 8 includes two support plates 801, which support a horizontal plate 802. The bottoms of the two support plates 801 are fixedly connected to the front and rear ends of the top left side of the base 1, providing a stable mounting position for the detection component 8. The top of each support plate 801 is fixedly connected to the same horizontal plate 802, which is used to mount an optical sensor 803. The bottom front and rear ends of the horizontal plate 802 are also fixedly connected to optical sensors 803, which monitor changes in the position of the nonwoven fabric. A drive component 9 is located at the bottom of the correction mechanism 2. The drive assembly 9, which provides power to the correction mechanism 2, includes a servo motor 901. The servo motor 901 acts as a power source, providing driving force. The bottom of the servo motor 901 is fixedly connected to the top left end of the base 1 to ensure stable installation. An eccentric wheel 902 is fixedly connected to the output end of the servo motor 901. The eccentric wheel 902 converts the rotational motion of the servo motor 901 into a specific trajectory motion. Slide grooves 903 are provided on both the left and right sides of the eccentric wheel 902, providing a motion track for the slider 904. A slider 904 is slidably connected to the inner wall of each of the two slide grooves 903. The slider 904 moves within the slide groove 903, transmitting power. A connecting rod 905 is fixedly connected to the top of the slider 904. The motion of slider 904 is transmitted to adjusting frame 204. A limit block 906 is slidably connected to the outer wall of connecting rod 905. The limit block 906 limits the range of motion of connecting rod 905 to make its motion more precise. Fixing frames 907 are fixedly connected to the front and rear sides of the limit block 906. The fixing frames 907 are used to fix the limit block 906. The bottoms of both fixing frames 907 are fixedly connected to the top of base 1 to ensure that the fixing frames 907 are firmly installed. The top of connecting rod 905 is fixedly connected to the bottom front side of adjusting frame 204, allowing adjusting frame 204 to move with connecting rod 905. The correction mechanism 2 includes a support block 201, which supports rotating shaft 202 and is fixed to base 1. The bottom of support block 201 is fixedly connected to the top left end of base 1.To provide stable support for the correction mechanism 2, a rotating shaft 202 is fixedly connected to the top of the support block 201. The rotating shaft 202 allows the U-shaped block 203 to rotate around it. The same U-shaped block 203 is rotatably connected to both the left and right ends of the rotating shaft 202. The U-shaped block 203 connects the rotating shaft 202 to the adjusting frame 204. The adjusting frame 204 is fixedly connected to the top of the U-shaped block 203. The adjusting frame 204 drives the adjusting shaft 205 to move and achieve correction. The adjusting shaft 205 is rotatably connected to the top of the adjusting frame 204. The adjusting shaft 205 contacts the nonwoven fabric and adjusts its conveying direction. The tops of the feeding component 5, the cutter shaft component 6, and the winding component 7 are all equipped with compensation components 10. The compensation components 10 are used to compensate for the air pressure in various parts to ensure stable slitting. Multiple compensation components 10 are packaged together. The system includes multiple PLC controllers 1001, which receive and process data from pressure sensors 1002 and control compensating air pumps 1003. The rear sides of each PLC controller 1001 are fixedly connected to the front side of the mounting plate 4, providing mounting positions. Pressure sensors 1002 are fixedly connected to the right side of each PLC controller 1001, monitoring real-time pressure changes at various locations. Compensating air pumps 1003 are also fixedly connected to the right side of each pressure sensor 1002, compensating for pressure changes at corresponding locations according to instructions from the PLC controllers 1001. A collection mechanism 3 is provided on the inner wall of the base 1 to collect debris generated during the cutting process.

[0041] Specifically, the nonwoven fabric begins to be conveyed, first passing through the correction mechanism 2. The support block 201 of the correction mechanism 2 is firmly fixed to the top left end of the base 1. The rotating shaft 202 connects the support block 201 and the U-shaped block 203, allowing the U-shaped block 203 to rotate around the shaft. The adjusting shaft 205 at the top of the adjusting frame 204 on the U-shaped block 203 contacts the nonwoven fabric, guiding its conveying path. The two support plates 801 of the detection component 8 stand at the front and rear ends of the top left side of the base 1, and the horizontal plate 802 is placed on the support plates 801. The optical path sensor 803 at the bottom constantly monitors the nonwoven fabric conveying path. Once the nonwoven fabric deviates from the preset path due to wear of the guide roller, the optical path sensor 803 quickly captures it and transmits the signal to the drive component 9. The servo motor 901 of the drive component 9 is then started. When the nonwoven fabric shifts backward, the optical path sensor 803 transmits the signal to the drive component 9, and the servo motor 901 drives the eccentric wheel 902 to rotate clockwise, causing the slider 904 to move along the slide groove 903. The adjusting frame 204 is driven to rotate clockwise around the rotating shaft 202 via the connecting rod 905, which in turn drives the adjusting shaft 205 to tilt forward and correct the nonwoven fabric that has shifted backward. When the nonwoven fabric shifts forward, it runs in the opposite direction. The compensation components 10 distributed on the top of the feeding component 5, the cutter shaft component 6, and the winding component 7 work synchronously. The air pressure sensors 1002 at each position sense the air pressure changes in their respective locations in real time. When the guide roller wear causes uneven force on the nonwoven fabric, resulting in air pressure fluctuations, the air pressure sensor 1002 transmits the data to the corresponding PLC controller 1001. The PLC controller 1001 accurately controls the compensation air pump 1003 according to the preset program to compensate for the air pressure demand at the corresponding position. By adjusting the air pressure, the air pressure stability of the slitting machine is more comprehensively controlled, reducing the impact of local air pressure fluctuations on the overall operation and ensuring the stable delivery of nonwoven fabric in all key parts of the slitting machine, thus guaranteeing the slitting quality and stable operation of the equipment.

[0042] Reference Figure 2 , Figure 4 and Figure 5The collection mechanism 3 is used to collect debris generated during the slitting of nonwoven fabric. The collection mechanism 3 includes a debris collection box 301, which serves as a container for collecting debris. The outer wall of the debris collection box 301 is slidably connected to the inner wall of the base 1, allowing for movable installation of the debris collection box 301 within the base 1. Positioning blocks 302 are fixedly connected to both the left and right sides of the debris collection box 301. The positioning blocks 302 are used to precisely position the debris collection box 301 within the base 1. The tops of both positioning blocks 302 have engaging mechanisms. The slot 303 and the engaging ball 305 cooperate to fix the base 1. Positioning slots 304 are provided on both the left and right sides of the inner wall of the base 1. These slots provide sliding tracks for the positioning block 302 and assist in positioning. The inner walls of the two positioning slots 304 are slidably connected to the outer walls of the corresponding positioning blocks 302, ensuring the accuracy and stability of the positioning block 302 installation. Engaging balls 305 are slidably connected to the inner walls of the two engaging slots 303. The engaging balls 305 slide within the engaging slots 303 to lock the debris collection box 301. For locking and unlocking, springs 306 are fixedly connected to the top of each of the two locking balls 305. The springs 306 provide elastic force to keep the locking balls 305 locked. The outer walls of the two springs 306 are slidably connected to the inner walls of the corresponding positioning grooves 304, ensuring stable operation of the springs 306 within the positioning grooves 304. A movable component 307 is provided on the front side of the debris collection box 301. The movable component 307 facilitates the operator's movement of the debris collection box 301. The movable component 307 includes a movable bracket 3071. The movable support 3071 is used to connect the debris collection box 301 and the movable handle 3072. The rear side of the movable support 3071 is fixedly connected to the front side of the debris collection box 301, so that the movable support 3071 and the debris collection box 301 are stably connected. The movable handle 3072 is fixedly connected to the top of the movable support 3071. The movable handle 3072 provides the operator with a gripping point for easy pulling. The four corners of the bottom of the debris collection box 301 are fixedly connected to the casters 3073, which enable the debris collection box 301 to move flexibly.

[0043] Specifically, the debris generated during cutting falls into the base 1. At this time, the debris collection box 301 plays a collecting role. Through the sliding connection between its outer wall and the inner wall of the base 1, it can be stably placed inside the base 1 to collect the debris. When the debris collection box 301 is inserted into the base 1, the positioning block 302 slides along the positioning groove 304 for precise installation. The locking structure composed of the locking ball 305 and the spring 306 further secures the debris collection box 301. Under the elastic force of the spring 306, the locking ball 305 partially embeds into the locking groove 303, preventing the collection box from... Unexpected slippage ensures the reliability of the collection process. When debris needs to be cleaned, the moving component 307 comes into play. The moving bracket 3071 is fixed to the front of the debris collection box 301, and the moving handle 3072 on its top provides a convenient point of leverage for the operator. The operator can easily pull the debris collection box 301 out of the base 1 by holding the moving handle 3072 and rolling the casters 3073. The casters 3073 are designed at the four corners of the bottom of the debris collection box 301, making the collection box move flexibly and improving the efficiency of debris cleaning.

[0044] Reference Figure 1 and Figure 2 Support legs 11 are fixedly connected to the four corners of the base 1. The support legs 11 support the base 1 and keep it stable. Conical feet 12 are fixedly connected to the bottom of the multiple support legs 11. The conical feet 12 increase the stability of contact with the ground and distribute the weight. Rubber pads 13 are fixedly connected to the bottom of the multiple conical feet 12. The rubber pads 13 play a role in anti-slip and reduce vibration transmission. A central controller 14 is fixedly connected to the front left side of the top of the base 1. The central controller 14 is the control core of the entire system. The central controller 14 is electrically connected to the feeding component 5 to control the speed and start / stop of the feeding component 5 to convey nonwoven fabric. The central controller 14 is electrically connected to the cutter shaft component 6 to realize the control of the cutting operation of the cutter shaft component 6. The central controller 14 is connected to the winding part. The component 7 is electrically connected and can control the winding speed and tension of the nonwoven fabric after slitting. The central controller 14 is electrically connected to the optical path sensor 803 and receives the nonwoven fabric conveying path offset signal monitored by the optical path sensor 803. The central controller 14 is electrically connected to the servo motor 901 and controls the operation of the servo motor 901 to drive the correction mechanism 2 according to the nonwoven fabric offset. The central controller 14 is electrically connected to the PLC controller 1001 and coordinates the control of the PLC controller 1001 on the air pressure compensation of each part. The central controller 14 is electrically connected to the air pressure sensor 1002 and obtains the real-time air pressure data of each part. The central controller 14 is electrically connected to the compensation air pump 1003 and controls the compensation air pump 1003 to perform air pressure compensation on the corresponding parts according to the air pressure data.

[0045] Specifically, the support leg 11 is used to support the base 1 to keep it stable, the tapered foot 12 increases the stability of contact with the ground and distributes the weight, the rubber pad 13 plays a role in anti-slip and reduces vibration transmission, and the central controller 14 serves as the control core of the entire system.

[0046] Working principle: The nonwoven fabric begins to be conveyed, first passing through the correction mechanism 2. The support block 201 of the correction mechanism 2 is firmly fixed to the top left end of the base 1. The rotating shaft 202 connects the support block 201 and the U-shaped block 203, allowing the U-shaped block 203 to rotate around the shaft. The adjusting shaft 205 at the top of the adjusting frame 204 on the U-shaped block 203 contacts the nonwoven fabric, guiding its conveying path. The two support plates 801 of the detection component 8 stand at the front and rear ends of the top left side of the base 1, and the horizontal plate 802 is placed on the support plates 801. The optical path sensor 803 at the bottom constantly monitors the nonwoven fabric conveying path. Once the nonwoven fabric deviates from the preset path due to wear of the guide roller, the optical path sensor 803 quickly captures it and transmits the signal to the drive component 9. The servo motor 901 of the drive component 9 is started upon command. When the nonwoven fabric shifts backward, the optical path sensor 803 transmits the signal to the drive component 9, and the servo motor 901 drives the eccentric wheel 902 to rotate clockwise. The slider 904 moves along the slide groove 903. The mechanism moves by pushing the adjusting frame 204 to rotate clockwise around the rotating shaft 202 via the connecting rod 905, thereby causing the adjusting shaft 205 to tilt forward and correct the nonwoven fabric that has shifted backward. When the nonwoven fabric shifts forward, it reverses direction. The compensation components 10 distributed on the top of the feeding component 5, the cutter shaft component 6, and the winding component 7 work synchronously. The air pressure sensors 1002 at each position sense the air pressure changes in their respective locations in real time. When the guide roller wears and causes uneven force on the nonwoven fabric, resulting in air pressure fluctuations, the air pressure sensors 1002 transmit the data to the corresponding PLC controller 1001. The PLC controller 1001, according to the preset program, precisely controls the compensation air pump 1003 to compensate for the air pressure requirements at the corresponding positions. By adjusting the air pressure, the air pressure stability of the slitting machine is more comprehensively controlled, reducing the impact of local air pressure fluctuations on the overall operation. This ensures the stable delivery of nonwoven fabric in all key parts of the slitting machine, guaranteeing slitting quality and stable equipment operation.

[0047] Furthermore, when the nonwoven fabric slitting machine is running, the slitting debris generated will fall into the base 1. At this time, the debris collection box 301 plays a collecting role. Through the sliding connection between the outer wall and the inner wall of the base 1, it can be stably placed inside the base 1 to collect debris. When the debris collection box 301 is inserted into the base 1, the positioning block 302 slides along the positioning groove 304 for easy and precise installation. The locking structure composed of the locking ball 305 and the spring 306 further fixes the debris collection box 301. Under the elastic force of the spring 306, the locking ball 305 is partially embedded in the locking groove 303. To prevent the collection box from accidentally sliding out and to ensure the reliability of the collection process, the moving component 307 comes into play when debris needs to be cleaned. The moving bracket 3071 is fixed to the front of the debris collection box 301, and the moving handle 3072 on its top provides a convenient point of leverage for the operator. The operator can easily pull the debris collection box 301 out of the base 1 by holding the moving handle 3072 and rolling the casters 3073. The casters 3073 are designed at the four corners of the bottom of the debris collection box 301, making the collection box move flexibly and improving the efficiency of debris cleaning.
