Description

Technical Field

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

[0002] Chinese Patent Application No. CN202421805057.4 discloses a triangular folding ultrasonic welding machine. A second motor drives a rotating shaft and a connecting frame to rotate, which in turn drives a tension roller to perform circular motion, thereby adjusting the tension of the curtain fabric to ensure it is flat and wrinkle-free. Multiple fixing plates are fixedly connected to the left side of the fixed frame, and a fixing rod is fixedly connected to the adjacent side of every two fixing plates. A rotating roller is rotatably connected to the outside of the fixing rod. Two support frames are fixedly connected to the top of the fixed frame, and rotating rollers are rotatably connected to the outside of each support frame. A triangular folding frame is fixedly connected to the right side of the fixed frame. The rotating roller, support frames, rotating roller, and triangular folding frame work together to guide the curtain fabric correctly through the machine and accurately fold it at the triangular folding frame, preparing it for subsequent welding.

[0003] The aforementioned patent discloses that the tension of the cord fabric is adjusted by the displacement of the tension roller. The cord fabric then passes outside the rotating roller two and finally covers the outside of the triangular folding frame. At this point, the cord fabric is folded in half triangularly by the triangular folding frame. The cord fabric passes between two pressing rollers, which presses the folded cord fabric. However, when folding the cord fabric triangularly by the triangular folding frame, the cord fabric needs to be folded manually on the triangular folding frame. After folding, the cord fabric still needs to be manually pulled onto the pressing roller. This operation method increases the working time and has low work efficiency.

[0004] Therefore, how to improve the folding efficiency of a nonwoven fabric folding device is a technical problem that needs to be solved by those skilled in the art. Summary of the Invention

[0005] In view of this, the purpose of this application is to overcome the shortcomings of the prior art and provide a nonwoven fabric folding device to improve the automatic folding function of a nonwoven fabric folding device.

[0006] To achieve the above objectives, this utility model provides a nonwoven fabric folding device, comprising:

[0007] The bracket is used to support the tripod, and a partition is installed at the bottom of the tripod;

[0008] Folding mechanism, used to assist in folding nonwoven fabrics;

[0009] The cleaning mechanism is located above the tripod;

[0010] Unwinding roll and take-up roll;

[0011] A conveying mechanism, located below the folding mechanism;

[0012] The folding mechanism includes two connecting plates and two mounting plates symmetrically distributed along the partition. Folding plates are mounted on the two connecting plates by screws. A mounting plate is installed below the connecting plates. Several rotating shafts are mounted on the mounting plates. The rotating shafts are arranged in a linear array relative to the rotating shafts. Ball bearings are installed on both the folding plates and the rotating shafts.

[0013] The tripod is equipped with a support roller, and the tripod is tilted at an angle of 50-60 degrees.

[0014] The cleaning mechanism includes a cylinder, inside which a cleaning brush is rotatably connected via a double-ended screw. Rollers are installed at both ends of the double-ended screw, and two rotating rods are installed on the cylinder.

[0015] The conveying mechanism includes two conveying rollers located directly below the partition. A limit roller is installed below one of the conveying rollers, and a tension roller is installed between the limit roller and the winding roller.

[0016] A connecting frame is installed on the side of the bracket near the folding mechanism, and a baffle is installed on the connecting frame. The baffle is fixedly connected to the mounting plate.

[0017] A support frame is installed on the top of the bracket, a rotating roller is installed on the top of the support frame, a connecting rod is installed below the rotating roller, the connecting rod is fixedly connected to the tripod, and a connecting roller is installed below the connecting rod.

[0018] The cylinder is rotatably connected to the connecting frame via a rotating rod.

[0019] The screw is rotated by a motor, and the screw is a reciprocating screw.

[0020] An auxiliary roller is mounted on the support, and the auxiliary roller is located on the side where the unwinding roller exits.

[0021] Several of the said shafts are connected by gears and racks, and one of the said shafts is rotated by a motor.

[0022] This invention discloses a nonwoven fabric folding device. The center line of the nonwoven fabric is aligned with a partition. A motor is started, driving a screw to rotate. The screw moves folding plates towards the nonwoven fabric. As the two folding plates move towards the partition, they push the nonwoven fabric, folding it in half. The ball bearings on the folding plates reduce friction between the plates and the fabric, allowing for smoother movement. When the folding plates reach the end of the partition, the motor stops, and the plates stop moving, holding the fabric in place to prevent loosening at the folded ends. Simultaneously, the unwinding roller and rotating shaft are activated. The motor drives the rotating shaft, and the ball bearings on it increase the contact area, allowing them to contact the nonwoven fabric. The rotating shaft rotates the ball bearings, which in turn move the fabric downwards. The two rotating shafts convey the folded nonwoven fabric downwards, and the fabric is then conveyed again by two conveying rollers. This invention uses folding plates and rotating rollers to automatically fold nonwoven fabric, saving labor and improving work efficiency.

Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0032] The core of this utility model is to provide a non-woven fabric folding device to improve the effective load capacity of a non-woven fabric folding device.

[0033] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0034] Please refer to Figures 1 to 5 The present invention discloses a non-woven fabric folding device, comprising: a bracket 1 for supporting a tripod 2, wherein a partition 201 is installed at the bottom of the tripod 2;

[0035] Folding mechanism 3 is used to assist in folding the non-woven fabric;

[0036] Cleaning mechanism 4 is located above tripod 2;

[0037] Unwinding roller 5 and winding roller 7;

[0038] Conveying mechanism 6, located below folding mechanism 3;

[0039] The folding mechanism 3 includes two connecting plates 306, which are symmetrically distributed along the partition 201. Folding plates 302 are mounted on the two connecting plates 306 via screws 305. A mounting plate 301 is mounted below the connecting plates 306. Several rotating shafts 303 are mounted on the mounting plate 301. The rotating shafts 303 are arranged in a linear array relative to the rotating shafts 303. Ball bearings 304 are mounted on both the folding plate 302 and the rotating shafts 303.

[0040] A support roller 202 is installed on the tripod 2, and the tilt angle of the tripod 2 is 50-60 degrees.

[0041] The cleaning mechanism 4 includes a cylinder 401. Inside the cylinder 401, a cleaning brush 404 is rotatably connected via a double-headed screw 402. Rollers 403 are installed at both ends of the double-headed screw 402. Two rotating rods 405 are installed on the cylinder 401 to prevent the nonwoven fabric from deviating during conveying. When the nonwoven fabric is conveyed, it can drive the rollers 403 to rotate. The rotation of the rollers 403 drives the double-headed screw 402 to rotate. The rotation of the double-headed screw 402 drives the cleaning brush 404 to reciprocate. The cleaning brush 404 cleans the dust on the surface of the nonwoven fabric.

[0042] The conveying mechanism 6 includes two conveying rollers 601 located directly below the partition 201. A limit roller 602 is installed below one of the conveying rollers 601, and a tension roller 603 is installed between the limit roller 602 and the winding roller 7.

[0043] A connecting frame 101 is installed on the side of the bracket 1 near the folding mechanism 3. A baffle 102 is installed on the connecting frame 101 and is fixedly connected to the mounting plate 301.

[0044] A support frame 103 is installed on the top of the bracket 1, a rotating roller 104 is installed on the top of the support frame 103, a connecting rod 105 is installed below the rotating roller 104, the connecting rod 105 is fixedly connected to the tripod 2, and a connecting roller 106 is installed below the connecting rod 105.

[0045] The cylinder 401 is rotatably connected to the connecting frame 101 via the rotating rod 405.

[0046] The screw 305 is rotated by a motor. The screw 305 is a reciprocating screw, and two threaded grooves with the same pitch and opposite helical directions are opened on the screw 305.

[0047] An auxiliary roller 107 is installed on the bracket 1. The auxiliary roller 107 is located on the side of the unwinding roller 5 that discharges material.

[0048] Several rotating shafts 303 are connected by gears and racks, and one of the rotating shafts 303 is rotated by a motor.

[0049] In use, the motor drives the unwinding roller 5 to feed the nonwoven fabric. The worker passes the nonwoven fabric through the auxiliary roller 107 and then pulls it upwards, allowing it to pass sequentially through the connecting roller 106 and the rotating roller 104. The nonwoven fabric is then moved towards the tripod 2, where it needs to be tightly pressed against the tripod 2. After passing the tripod 2, the rotating rod 405 is rotated to place the cylinder 401 above the nonwoven fabric. The cylinder 401 limits the movement of the nonwoven fabric, preventing it from deviating during transport. The transport of the nonwoven fabric also drives the roller 403 to rotate. Rotation of 403 drives the double-headed screw 402 to rotate, which in turn drives the cleaning brush 404 to reciprocate. The cleaning brush 404 cleans the dust on the surface of the non-woven fabric, moving the non-woven fabric to one side of the partition 201 of the tripod 2. At this point, the center line of the non-woven fabric is aligned with the partition 201, and the length of the non-woven fabric falling is longer than the height of the partition 201. At this point, the operation of the unwinding roller 5 is stopped, allowing the non-woven fabric to contact the rotating shaft 303. The motor is then started, driving the screw 305 to rotate. The screw 305 moves the folding plate 302 toward the non-woven fabric. When the two folding plates 302 move towards the partition 201, they push the nonwoven fabric, causing it to fold in half. Because the folding plates 302 are equipped with ball bearings 304, these ball bearings reduce the friction between the folding plates 302 and the nonwoven fabric, allowing the folding plates 302 to move more smoothly. When the folding plates 302 reach the end of the partition 201, the motor stops working, and the folding plates 302 also stop moving. The folding plates 302 then hold the nonwoven fabric in place, preventing the folded ends from unraveling. At this time, the unwinding roller 5 and the rotating shaft 303 are simultaneously activated, and the unwinding roller 5 continues to fold the nonwoven fabric... The fabric is unwound, and the motor drives the rotating shaft 303 to rotate. The ball bearings 304 on the rotating shaft 303 can increase the contact area of ​​the rotating shaft 303. The ball bearings 304 can contact the non-woven fabric. When the rotating shaft 303 rotates, it drives the ball bearings 304 to rotate. The ball bearings 304 drive the non-woven fabric to move downward. The rotating shaft 303 conveys the folded non-woven fabric downward. The non-woven fabric is conveyed by two conveying rollers 601. Then, through the operation of the worker, the folded non-woven fabric passes through the limiting roller 602 and the tensioning roller 603 in sequence. Finally, the folded non-woven fabric is wound up by the winding roller 7.
