Description

Technical Field

[0001] This utility model relates to the field of fabric production equipment technology, and in particular to a fabric edge trimming device. Background Technology

[0002] In the production of woven films (including various fabrics, non-woven fabrics, and plastic films), due to the requirements of loom width or subsequent stretching and shaping processes, the produced woven films often have uneven thickness and rough edges on both sides. If these edges are not removed in time, they will affect the appearance quality, flatness, and process stability of the final roll material.

[0003] Most of the film edge trimming devices commonly available on the market adopt a fixed blade structure. The cutting position and effective width are locked after the equipment is installed, making it difficult to quickly adjust according to changes in product specifications, raw material characteristics, or process parameters. This rigid design results in poor equipment versatility. When switching to different types or widths of film, a lot of time is required to readjust or even replace parts, which not only reduces production efficiency but also increases maintenance costs and downtime losses.

[0004] Therefore, it is necessary to design a fabric edge trimming device. Utility Model Content

[0005] In order to overcome the shortcomings of existing fabric trimming devices, which mostly use fixed blades, are difficult to adjust, are cumbersome to debug during production changes, have poor versatility, affect efficiency and increase costs, this utility model provides a fabric trimming device.

[0006] A film edge trimming device includes a frame, a controller, a connecting frame, a discharge roller, a motor, a take-up roller, a pulley assembly, a support frame, an electric slide rail, an electric slider, a connecting block, a guide rod, a cutter, and a spring. The controller is mounted on the front side of the frame. Connecting frames are fixedly connected to both the front and rear sides of the top of the frame. The discharge roller is rotatably connected inside the front connecting frame, and a motor is mounted on the front connecting frame. The motor output shaft is connected to the discharge roller. The take-up roller is rotatably connected inside the rear connecting frame. Power is transmitted between the discharge roller and the take-up roller through a pulley assembly. Support frames are fixedly connected to the left and right sides of the top of the frame. An electric slide rail is installed between the two support frames. Electric sliders are slidably mounted on the left and right sides of the bottom of the electric slide rail. The motor, electric slide rail, and electric slider are all electrically connected to the controller. A connecting block is fixedly connected to the bottom of each electric slider. Multiple guide rods are slidably connected to each connecting block. A cutter is fixedly connected between the bottoms of the multiple guide rods on the same connecting block. Multiple springs are connected between the cutter and the corresponding connecting block.

[0007] Optionally, it also includes a screw, a support block, a slide rod, a fixed block, a pressure roller, a second spring, and a limit rod. The screw is rotatably connected to both ends of the left side of the frame, and the limit rod is fixedly connected to both ends of the right side of the frame. The screw is threadedly connected to the outside of the support block, and another support block is slidably connected to the outside of the limit rod. The slide rod is slidably connected to the inside of the support block, and a fixed block is fixedly connected to the top of the slide rod. The pressure roller is rotatably connected between the fixed blocks on the same side at the front and rear, and a second spring is connected between the support block and the fixed block on the same side at the left and right.

[0008] Optionally, it also includes bevel gears and handwheels. Bevel gears are fixedly connected to the bottom of the screw. Another bevel gear is rotatably connected to both ends of the left frame. A handwheel is fixedly connected to the left side of each bevel gear. The two bevel gears on the same side of the front and rear mesh with each other.

[0009] Optionally, it also includes a fixed frame and a storage box, with slots opened inside the frame, a fixed frame fixedly connected to the bottom of the frame, and a storage box slidably connected inside the fixed frame.

[0010] Optionally, it also includes a scale, with the scale fixedly connected to the front side of the electric slide rail.

[0011] Optionally, it also includes pointers, with pointers fixedly connected to the front of each electric slider, and the pointers all pointing to the scale.

[0012] Beneficial effects: 1. By using electric slide rails and electric sliders, the cutting distance can be precisely adjusted. The cutting position can be quickly set according to the width of the fabric and the requirements of the edge material, meeting the trimming needs of various product specifications and ensuring strong consistency of the width of the finished fabric. This solves the problems of existing fabric trimming devices, which mostly use fixed blades, are difficult to adjust, are cumbersome to debug during production changeover, have poor versatility, affect efficiency and increase costs.

[0013] 2. This utility model uses a bevel gear and a handwheel. The rotation of the handwheel drives the bevel gear on it to rotate. Since the bevel gear meshes with the bevel gear on the screw, the meshing transmission converts the vertical rotation of the handwheel into the horizontal rotation of the screw, causing the support block to slide down synchronously along the limit rod. This allows the pressure roller to flexibly adjust the contact pressure according to the different thicknesses or materials of the film, ensuring that the film is stable and does not deviate during the conveying process, while avoiding damage to the material.

[0014] 3. This utility model, by setting a fixed frame and a storage box, allows the trimmed scraps to fall directly into the storage box through the slot at the bottom of the equipment, and the trimmed scraps to fall directly into the storage box through the slot at the frame, thus achieving automatic centralized collection, avoiding the scraps from scattering and affecting the working environment, facilitating subsequent cleaning and recycling, reducing the amount of manual cleaning work, and improving the cleanliness and environmental protection level of the site.

Detailed Implementation

[0021] Example: A fabric edge trimming device, such as Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the machine includes a frame 1, a controller 101, a connecting frame 2, a discharge roller 3, a motor 4, a take-up roller 5, a pulley assembly 6, a support frame 7, an electric slide rail 8, an electric slider 9, a connecting block 10, a guide rod 11, a cutter 12, and a spring 13. The controller 101, an MCT150 flying shear controller, is mounted on the front side of the frame 1. Connecting frames 2 are welded to both the front and rear sides of the top of the frame 1. The discharge roller 3 is rotatably connected inside the front connecting frame 2, and a motor 4 is mounted on the front connecting frame 2. The output shaft of the motor 4 is connected to the discharge roller 3. The take-up roller 5 is rotatably connected inside the rear connecting frame 2. The discharge roller 3 and the take-up roller 5 are connected by a pulley assembly. Component 6 transmits power. Support frames 7 are welded to the top left and right sides of the frame 1. Electric slide rails 8 are installed between the two support frames 7. Electric sliders 9 are slidably installed on the bottom left and right sides of the electric slide rails 8 through slide grooves. Motor 4, electric slide rails 8 and electric sliders 9 are all electrically connected to controller 101. Connecting blocks 10 are welded to the bottom of electric sliders 9. Two guide rods 11 are symmetrically distributed front and back on each connecting block 10 through slide grooves. Cutters 12 are welded between the bottoms of the two guide rods 11 on the same connecting block 10. Two springs 13 are connected between the cutter 12 and the corresponding connecting block 10. Springs 13 are sleeved on the outside of the guide rods 11.

[0022] like Figure 1 , Figure 4 and Figure 5 As shown, it also includes a screw 14, a support block 15, a slide rod 16, a fixing block 17, a pressure roller 18, a spring 19, a limiting rod 22, a bevel gear 20, and a handwheel 21. The screw 14 is rotatably connected to both the front and rear ends of the left side of the frame 1, and the limiting rod 22 is welded to both the front and rear ends of the right side of the frame 1. Each screw 14 is threadedly connected to a support block 15. Each limiting rod 22 is slidably connected to another support block 15 via a sliding groove. Each support block 15 is slidably connected to a slide rod 16 via a sliding groove. The top of each slide rod 16... A fixed block 17 is welded on, and a pressure roller 18 is rotatably connected between the fixed blocks 17 on the front and rear sides, which can eliminate wrinkles and looseness during the conveying process. A second spring 19 is connected between the support block 15 on the left and the fixed block 17 on the same side. The second spring 19 is sleeved on the outside of the slide rod 16. A bevel gear 20 is welded to the bottom of the screw 14. Another bevel gear 20 is rotatably connected to both ends of the left frame 1. A handwheel 21 is welded to the left side of the bevel gear 20. The two bevel gears 20 on the front and rear sides mesh with each other.

[0023] like Figure 1 and Figure 2As shown, it also includes a fixed frame 23, a storage box 24, a scale 25, and a pointer 26. The frame 1 has a slot 102 inside. The fixed frame 23 is welded to the bottom of the frame 1. The storage box 24 is slidably connected to the fixed frame 23 through a slide groove to collect the trimming scraps. The scale 25 is welded to the front of the electric slide rail 8. The pointer 26 is welded to the front of the electric slider 9. The pointer 26 points to the scale 25, which makes it easy for the operator to read the cutting distance intuitively.

[0024] In the initial state, the left support blocks 15 are all located at the top of the screw 14, and the pressure rollers 18 are all in a high position. When this device is needed, the operator first puts the roll of fabric to be trimmed on the outside of the free end of the output roller 3, and then pulls the movable end of the fabric roll through the bottom of the front and rear pressure rollers 18 in sequence, and finally fixes the movable end of the fabric to the outside of the take-up roller 5. Then the operator turns the handwheel 21 in sequence. The rotation of the handwheel 21 drives the upper bevel gear 20 to rotate. Since the bevel gear 20 meshes with the upper bevel gear 20 of the screw 14, the meshing transmission converts the vertical rotation of the handwheel 21 into the horizontal rotation of the screw 14, so that the support blocks 15 slide down synchronously along the limit rod 22, thereby adjusting the contact pressure between the pressure rollers 18 and the fabric. The second spring 19 always applies a downward elastic force to the fixed block 17, so that the pressure rollers 18 are tightly attached to the fabric.

[0025] After adjustment, the operator, according to the trimming requirements of the fabric edge, drives the electric slider 9 to slide left and right along the electric slide rail 8 via the controller 101. Simultaneously, the operator can precisely control the spacing between the left and right cutters 12 by pointing the pointer 26 in front of the electric slider 9 to the scale 25 on the front side of the electric slide rail 8, thus adjusting the horizontal position of the cutters 12. After adjustment, the electric slider 9 is turned off, and then the motor 4 can be started via the controller 101. The output shaft of the motor 4 rotates, driving the discharge roller 3 to rotate, which in turn removes the fabric edge to be trimmed. As the fabric is released, the discharge roller 3 transmits power to the take-up roller 5 via the belt pulley assembly 6, causing the take-up roller 5 and the discharge roller 3 to rotate synchronously. The fabric is then conveyed backward under the traction of the discharge roller 3 and the take-up roller 5. When it passes under the cutter 12, the left and right cutters 12 press tightly against the edge of the fabric under the elastic force of the spring 13, quickly cutting off the edge material of the fabric as it moves. The take-up roller 5 then rolls up the fabric after it has been pulled and trimmed. The edge material produced by trimming falls into the storage box 24 through the slot 102 under the action of gravity and is collected in a concentrated manner.

[0026] After the entire roll of film is trimmed, turn off motor 4. The output roller 3 and take-up roller 5 will stop rotating. The trimmed roll of film can then be taken out from the right side of take-up roller 5. Finally, remove the storage box 24 from the fixed frame 23 to empty it, and then push it back in to reset it. This completes the use of the device.
