Description

Technical Field

[0001] This utility model relates to the technical field of breathable membrane production edge cutting and winding device, specifically a breathable membrane production edge cutting and winding device. Background Technology

[0002] Breathable membranes are high-molecular functional materials with microporous structures, widely used in medical protective clothing, hygiene products, packaging materials, and building waterproofing. Their core characteristic lies in achieving one-way or two-way breathability through their microporous structure, while simultaneously blocking liquids and microorganisms. As downstream industries demand higher product performance, the production process of breathable membranes is gradually developing towards higher precision, higher efficiency, and lower energy consumption. Among these processes, edge trimming and film rolling are crucial steps that directly affect the product's yield, appearance quality, and adaptability to subsequent processing.

[0003] In existing breathable membrane production, excess edges and corners are cut off by a cutting blade. The cut breathable membrane is then collected by a collecting roller. During the cutting process, waste edges from both sides of the breathable membrane accumulate messily on the ground, requiring frequent manual cleaning, which consumes manpower and time. Therefore, we have proposed a breathable membrane production cutting and rolling device to solve the above-mentioned problems. Utility Model Content

Guide rollers are rotatably provided inside both sets of material feeding troughs. Material receiving components are provided on both sides of the bottom of the frame. A conveying roller is provided on the top left side of the frame.

[0007] The receiving assembly includes a hollow sleeve and a support plate. Hollow sleeves are rotatably provided on both sides of the bottom of the frame. A cylinder is provided inside the hollow sleeve. The output end of the cylinder is slidably connected to the hollow sleeve. A moving block is provided at the output end of the cylinder. Multiple sets of drive plates are hinged to the outer wall of the moving block. A support plate is hinged to one end of each set of drive plates. Connecting plates are hinged to both sides of the inner wall of each set of support plates. One end of each set of connecting plates is hinged to the outer wall of the hollow sleeve.

[0008] A further improvement is that: one end of the two sets of hollow sleeves is connected by a rotating rod, a drive rod is rotatably provided at the bottom of the frame, and pulleys are installed on both the rotating rod and the drive rod, and the two sets of pulleys are connected by a transmission belt.

[0009] A further improvement is that the moving component includes a movable sleeve and a bidirectional lead screw. Movable sleeves are installed on the side walls of both sets of cutting blades. A bidirectional lead screw is rotatably provided inside the fixed plate. Slider blocks are slidably provided on both sides inside the fixed plate. Both sets of sliders are threadedly connected to the bidirectional lead screw. The bottom of both sets of sliders is connected to the movable sleeve on the same side through a connecting block.

[0010] A further improvement is that a drive gear is installed at one end of each of the two sets of conveying rollers, and the two sets of drive gears mesh with each other.

[0012] A further improvement is that: both sides of the limiting roller are provided with limiting plates, and both sets of limiting plates are threadedly connected with locking rods.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: When the breathable membrane production edge cutting and rolling device is used, the produced breathable membrane is conveyed by the conveying roller, and the tension of the breathable membrane is adjusted by the tension roller. Then, the limiting plates on both sides of the limiting roller surface are used to limit the breathable membrane to avoid deviation and error in edge cutting. After the breathable membrane is limited, it enters the fixed plate. The cutting roller and the edge cutting blades on both sides of the fixed rod cut the breathable membrane. The breathable membrane is then conveyed to the outside by the conveying roller and collected by the receiving roller. The waste collection roller is inserted into the hollow sleeve in advance and supported by the receiving component. At this time, the waste edge after the breathable membrane is cut is connected to the waste collection roller through the guide roller inside the two side feeding troughs. The rotation of the rotating rod drives the waste collection roller on both sides to rotate and collect the waste edge, avoiding the waste edge from being piled up messily on the ground after being cut.

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.

[0020] Please see Figure 1-4 This utility model provides a technical solution: a breathable membrane production edge cutting and rolling device, including a frame 1;

[0021] Two sets of conveyor rollers 2 are provided on the top right side of the frame 1. Each set of conveyor rollers 2 has a drive gear 25 mounted at one end, and the two sets of drive gears 25 mesh with each other. A tension roller 3 is provided on the left side of the top conveyor rollers 2 of the frame 1. The top of the frame 1 is connected to the tension roller 3 via an adjusting assembly 4. The adjusting assembly 4 includes a mounting plate 401 and a return spring 402. Mounting plates 401 are provided on both sides of the top of the frame 1. Mounting blocks 26 are slidably mounted on the inner walls of both sets of mounting plates 401. The two sets of mounting blocks 26 are connected by the tension roller 3. Return springs 402 are provided on both sides of the top of both sets of mounting blocks 26, and one end of each set of return springs 402 is connected to the mounting plate 401. A limiting roller 5 is provided on the left side of the tension roller 3 at the top of the frame 1. Limiting plates 27 are slidably mounted on both sides of the limiting roller 5. Locking rods 28 are threadedly connected to both sets of limiting plates 27. A fixed plate 6 is provided on the left side, and a cutting roller 7 is rotatably provided inside the fixed plate 6. A fixed rod 8 is provided above the cutting roller 7 inside the fixed plate 6. Edge cutting blades 9 are slidably provided at both ends of the fixed rod 8. The fixed plate 6 is connected to the edge cutting blades 9 through a moving component 10. The moving component 10 includes a movable sleeve 101 and a bidirectional lead screw 102. Movable sleeves 101 are installed on the side walls of both sets of edge cutting blades 9. The bidirectional lead screw 102 is rotatably provided inside the fixed plate 6. Sliding blocks 23 are slidably provided on both sides inside the fixed plate 6. Both sets of sliding blocks 23 are threadedly connected to the bidirectional lead screw 102. The bottom of both sets of sliding blocks 23 are connected to the movable sleeve 101 on the same side through a connecting block 24. Feeding troughs 11 are provided on both sides of the frame 1. Guide rollers 12 are rotatably provided inside both sets of feeding troughs 11. Receiving components 13 are provided on both sides of the bottom of the frame 1. A conveying roller 14 is provided on the left side of the top of the frame 1.

[0022] In use, after the breathable membrane is produced, it is released by the feeding roller and enters the middle position of the two conveying rollers 2. The motor drives a single conveying roller 2 to rotate, and at the same time, one end of the conveying roller 2 drives the drive gear 25 to rotate. Since the two drive gears 25 are meshed, the two sets of conveying rollers 2 rotate simultaneously, conveying the breathable membrane. The breathable membrane passes above the tension roller 3. At this time, the two ends of the tension roller 3 drive the mounting blocks 26 to slide above the mounting plate 401. At the same time, the reset springs 402 on both sides of the mounting blocks 26 are stretched to adjust the tension of the breathable membrane. At this time, the breathable membrane passes below the limiting roller 5. According to different sizes of breathable membranes, the locking rods 28 on the limiting plates 27 at both ends of the limiting roller 5 can be rotated to make the limiting plates 27... After sliding upwards, the locking rod 28 is rotated to lock it, and the breathable membrane is limited by the limiting plate 27 to prevent the breathable membrane from shifting. At this time, after the breathable membrane enters the fixed plate 6, the cutting roller 7 and the cutting blades 9 on both sides of the fixed rod 8 cut the breathable membrane. When in use, depending on the size of the waste edge to be removed for different breathable membranes, the bidirectional lead screw 102 can be driven by the motor to rotate. The bidirectional lead screw 102 drives the sliders 23 on both sides to move. At the same time, the two sets of sliders 23 drive the movable sleeve 101 to slide above the fixed rod 8 through the connecting block 24. At this time, the cutting blades 9 move synchronously to facilitate cutting the breathable membranes of different sizes. After cutting, the breathable membrane is conveyed by the conveying roller 14 and then collected by the external receiving roller.

[0023] The receiving assembly 13 includes a hollow sleeve 131 and a support plate 132. Hollow sleeves 131 are rotatably provided on both sides of the bottom of the frame 1. A cylinder 15 is provided inside the hollow sleeve 131. The output end of the cylinder 15 is slidably connected to the hollow sleeve 131. A moving block 16 is provided at the output end of the cylinder 15. Multiple sets of drive plates 17 are hinged on the outer wall of the moving block 16. A support plate 132 is hinged at one end of each set of drive plates 17. Connecting plates 18 are hinged on both sides of the inner wall of each set of support plates 132. One end of each set of connecting plates 18 is hinged to the outer wall of the hollow sleeve 131. One end of each set of hollow sleeves 131 is connected by a rotating rod 19. A drive rod 20 is rotatably provided at the bottom of the frame 1. Pulleys 21 are installed on both the rotating rod 19 and the drive rod 20. The two sets of pulleys 21 are connected by a transmission belt 22.

[0024] After the waste collection roller is inserted into the hollow sleeve 131 in advance, the moving block 16 is moved by the cylinder 15. At this time, the moving block 16 drives the drive plate 17 to be adjusted through the hinge shaft. At the same time, the drive plate 17 drives the support plate 132 to open. Meanwhile, the connecting plate 18 on the inner wall of the support plate 132 is adjusted by the hinge shaft, so that multiple sets of support plates 132 are unfolded and contact the inner wall of the waste collection roller for support, thus completing the installation of the waste collection roller. At this time, the waste edge generated after the edge cutting process is guided by the guide roller 12 inside the feed trough 11 on both sides and then collected by the waste collection roller. At the same time, the motor drives the drive rod 20 to rotate, and the pulley 21 above the drive rod 20 drives the rotating rod 19 to rotate synchronously. At this time, the rotating rod 19 drives the hollow sleeve 131 on both sides to rotate, so that the waste collection roller rotates and continuously collects the waste edge.

[0025] Working Principle: When using the breathable membrane production edge-cutting and winding device, after the breathable membrane is produced, it is released through the feeding roller and enters the middle position of the two conveying rollers 2. The motor drives a single conveying roller 2 to rotate, and simultaneously, one end of the conveying roller 2 drives the drive gear 25 to rotate. Since the two drive gears 25 mesh, both sets of conveying rollers 2 rotate simultaneously, conveying the breathable membrane. The breathable membrane passes over the tension roller 3, at which point the two ends of the tension roller 3 drive the mounting blocks 26 to slide above the mounting plate 401. Simultaneously, the return springs 402 on both sides of the mounting blocks 26 are stretched, adjusting the tension of the breathable membrane. When the breathable membrane passes under the limiting roller 5, depending on the size of the breathable membrane, the locking rods 28 on the limiting plates 27 at both ends of the limiting roller 5 are rotated to allow the limiting plates 27 to slide upwards. The locking rods 28 are then rotated to lock the breathable membrane, thus limiting its position and preventing it from shifting. After the breathable membrane enters the fixed plate 6, the cutting roller 7, in conjunction with the cutting blades 9 on both sides of the fixed rod 8, cuts the edges of the breathable membrane. Depending on the size of the waste edge to be removed for different breathable membranes, the bidirectional lead screw 102 is driven by a motor to rotate, which in turn moves the sliders 23 on both sides. Simultaneously, the two sets of sliders 23 drive the movable sleeve 101 to slide above the fixed rod 8 via the connecting block 24. At this time, the cutting blade 9 moves synchronously, facilitating the cutting of breathable membranes of different sizes. After cutting, the breathable membrane is conveyed by the conveying roller 14 and then collected by the external receiving roller. After the waste collection roller is inserted into the hollow sleeve 131 in advance, the cylinder 15 drives the moving block 16 to move. At this time, the moving block 16 drives the drive plate 17 to adjust via the hinge shaft. At the same time, the drive plate 17 drives the support plate 132 to open. Meanwhile, the connecting plate 18 on the inner wall of the support plate 132 is adjusted via the hinge shaft, allowing multiple sets of supports to open. After the plate 132 is unfolded, it contacts the inner wall of the waste collection roller for support, completing the installation of the waste collection roller. At this time, the waste edges generated after the cutting process are guided by the guide rollers 12 inside the feed troughs 11 on both sides and then collected by the waste collection roller. At the same time, the motor drives the drive rod 20 to rotate, and the pulley 21 above the drive rod 20 drives the rotating rod 19 to rotate synchronously. At this time, the rotating rod 19 drives the hollow sleeves 131 on both sides to rotate, so that the waste collection roller rotates to continuously collect the waste edges, thereby completing a series of tasks. The contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0026] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
