Description

Technical Field

[0001] This invention discloses an edge-cutting device, and more particularly relates to an edge-cutting device for textiles. Background Technology

[0002] Fabric edge trimming machines are industrial devices specifically designed for cutting the edges of fabrics. They achieve high-precision cutting through mechanical, hydraulic, or ultrasonic technology and are widely used in the clothing and home textile industries. Ultrasonic cutting is generally used in large-scale automated processing in factories; it is more expensive and requires more precision. Most ordinary enterprises use hydraulic or pneumatic methods, or even manual methods. These devices are cheaper and easier to use. Therefore, pneumatic and hydraulic methods offer greater cutting force and can adapt to various fabrics, making them the most widely used.

[0003] Existing edge trimming machines typically set a take-up roller based on the required width of the fabric to be wound. The take-up roller is then fixed by partitions on both sides to prevent the fabric from shifting. The position of the cutting blade is then adjusted according to the position of the partitions. This process of adjustment is cumbersome. Therefore, existing technologies use electronic control, such as sensors or programming, to control the movement of the cutting blade and partitions, based on size input or sensor readings. While this method is precise, it has high maintenance costs and requires advanced installation techniques, making it unsuitable for small and medium-sized processing. Pneumatic methods are more commonly used. Therefore, an alternative solution based on pneumatic drive is proposed. After manual start-up, one-button adjustment and quick alignment of the cutting blade are achieved, while also facilitating the disassembly of the take-up roller. Summary of the Invention

[0004] The purpose of this invention is to provide a textile edge-cutting device to solve the above-mentioned problems.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a textile edge trimming device, comprising a main body, a drive motor mounted on the main body, a take-up roller for winding fabric connected to the drive motor, a rotating roller for tensioning the fabric at the front end of the take-up roller, a support plate for supporting the take-up roller at the drive motor location on the main body, a rotating shaft opposite to the drive motor located on one side of the main body located on the support plate, and the rotating shaft is rotatably connected to the main body, and a second rotating shaft opposite to the first rotating shaft is mounted on the drive motor.

[0008] Preferably, the adjusting component includes an abutment block that is slidably connected to the sleeve and used to push the insert to move. The abutment block is located at the end of the insert, and the end of the insert is provided with a groove for accommodating the abutment block. A spring is provided between the abutment block and the sleeve to push the abutment block. The elastic force of the spring is greater than the weight of the insert. The abutment surface between the abutment block and the groove of the insert is an inclined surface. The insert is provided with a connecting component connected to a take-up roller.

[0009] Preferably, the connecting assembly includes a protrusion rotatably connected at the position where the front end of the plug is embedded in the first winding roller. The middle of the protrusion is rotatably connected to the plug. At the end of the protrusion away from the first winding roller, there is a pressing block that is slidably connected to the plug. The pressing block is pressed down by the sleeve after it has been moved. A torsion spring is provided at the rotatable connection between the protrusion and the plug to push the protrusion back to its original position. The plug has a stepped cross-section. The inner part of the first winding roller has a groove for receiving and pressing the protrusion. The part with the larger diameter of the plug fits against the first winding roller.

[0010] Preferably, the main body of the device is provided with brackets on the front and rear sides of the threaded rod, the fixed block is slidably connected to the brackets, a push roller for pushing and clamping the fabric is provided on one side of the cutting blade, and a cylinder two for pushing the cutting blade and pushing the roller downwards is provided on the fixed block. The pushing roller moves downwards and abuts against the support roller, and the cutting blade and the pushing roller are staggered front and rear.

[0011] Preferably, the other side of the cutting blade is provided with an abutment roller for pushing the cut edge fabric. The abutment roller is longer than the cutting blade and the pushing roller, and the abutment roller is embedded downward. The main body of the device is provided with a second take-up roller for taking up the edge material at the lower end of the support roller. The surface of the abutment roller has a Velcro hook side, and the surface of the second take-up roller has adhesive.

[0012] Preferably, a second spring is provided between the abutting roller and the fixing block, and a third spring is provided between the support plate and the main body of the equipment.

[0013] Preferably, the main body of the device is provided with several switches for controlling cylinder one, drive motor and cylinder two. A stop switch for controlling cylinder one to stop air intake is provided at the piston of cylinder one and sleeve. A compression spring is provided between the piston of cylinder one and sleeve, and the elastic force of the compression spring is greater than the weight of sleeve, partition and plug.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] Firstly, after using this device, take-up roller 1 is placed on the support plate. At this time, the two sides of take-up roller 1 are opposite to rotating shaft 1 and rotating shaft 2 respectively. At the same time, manually turn on the switch of the control cylinder 1 on the main body of the equipment, so that cylinder 1 pushes the partition and plug-in, so that the plug-in is embedded into take-up roller 1. The plug-in is connected to take-up roller 1 through the connecting component, so that the drive motor drives take-up roller 1 to rotate after it is turned on, and rotating shaft 1 supports rotating shaft 2 to rotate, so that take-up roller 1 can be quickly connected to rotating shaft 1 and rotating shaft 2 and disassembled easily.

[0016] Secondly, by quickly attaching and detaching the take-up roller, the cylinder pushes the plug-in to connect with the take-up roller. The cylinder continues to push, causing the partition to move continuously, moving the partition and the take-up roller to the part of the take-up roller that is used to adhere to the fabric. At this point, due to the obstruction of the take-up roller's winding section and the partition's barrier, the wound fabric will not shift, ensuring the integrity of the winding. Furthermore, the movement of the partition drives the conversion component, causing the cutting blade to move synchronously with the partition, ensuring that the cutting blade's movement corresponds to the partition's position and that the cutting blade moves to the required width for cutting. This eliminates the need for manual adjustment, making it convenient and quick. The purely mechanical design eliminates the need for sensor adjustment and programming, avoiding damage and maintenance difficulties, and reducing costs. Synchronization can be achieved in a simple way.

[0017] Third, by pushing the abutment block and the elastic force of spring one being greater than the weight of the plug-in itself, after the plug-in is fully embedded, the interaction force of the winding roller and the pushing force of cylinder one causes spring one to compress. This ensures that as long as cylinder one pushes, the plug-in can be driven to complete the embedding, and then the partition continues to push to block.

[0018] Fourth, after the cutting blade has moved, the switch of the second cylinder is turned on, causing the second cylinder to push the cutting blade, the pushing roller, and the abutting roller downwards. The cutting blade cuts the excessively long parts of the fabric edge, while the pushing roller, acting in conjunction with the support roller, holds the fabric in place, ensuring that the fabric is flat during the cutting process and reducing wrinkles. The abutting roller is located at the cutting edge, moves downwards, and is longer than the cutting blade. When the cutting blade has moved enough to cut the fabric, the abutting roller pushes the cut edge downwards towards the second winding roller, thereby activating the effect of tightening the cut edge and preventing the cut edge from becoming loose and affecting the cutting, or from moving around and flying around.

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. In this description, it should be understood that the terms "upper," "lower," "front," "rear," "left," "right," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] A textile edge trimming device, such as Figures 1-10As shown, the device includes a main body 1, a drive motor 2, and a take-up roller 3 for winding fabric connected to the drive motor 2. A rotating roller 4 for tensioning the fabric is located at the front end of the take-up roller 3. A support plate 5 for supporting the take-up roller 3 is located on the main body 1 at the drive motor 2. A rotating shaft 6, opposite to the drive motor 2, is located on one side of the main body 1 at the support plate 5 and is rotatably connected to the main body 1. A rotating shaft 7, opposite to the rotating shaft 6, is located on the drive motor 2. Inserts 8, which are embedded in the take-up roller 3, are slidably connected to both the rotating shaft 6 and the rotating shaft 7. A device for tensioning the fabric is fitted onto the insert 8. The partition 9 is attached to the take-up roller 3, and the partitions 9 on both the left and right sides are attached to the take-up roller 3 and restrict the movement of the wound fabric. The main body 1 of the equipment is located between the take-up roller 3 and the rotating roller 4 and is provided with a support roller 10 for supporting the fabric. The support roller 10 is provided with a cutting blade 11 that slides relative to the main body 1 of the equipment. The main body 1 of the equipment is provided with a conversion component that links the partition 9 and the cutting blade 11. The partition 9 drives the cutting blade 11 to move synchronously through the conversion component. An adjustment component is provided between the left and right plugs 8 and the partition 9. Under normal use, the fabric is pulled along the main body 1 and continuously pulled towards the take-up roller 3. After being wound by the rotating roller 4, the fabric is taut through the switching of multiple rotating rollers 4, thus ensuring more stable fabric movement and reducing wrinkles. Next, by placing the take-up roller 3 on the support plate 5, the support plate 5 supports the take-up roller 3, aligning it with the insert 8 on the rotating shaft 6 and the rotating shaft 7. This ensures that the insert 8 is aligned within the cavity of the take-up roller 3. Simultaneously, by opening the adjusting component, the cylinder 13 pushes the partition 9 to move, causing the insert 8 to move synchronously and embed into the take-up roller 3. This connects the insert 8 to the take-up roller 3, and the partition 9 moves to fit snugly. On both sides of the take-up roller 3, the take-up roller 3 is composed of two tubes, one large and one small. The large tube corresponds to the width of the fabric to be taken up, and the small tube is connected to the plug 8. After the plug 8 is connected, the partition 9 continues to move through the adjustment component and fits against the side of the large tube of the take-up roller 3. This blocks the fabric on both sides to ensure that the fabric will not shift or tilt during take-up, ensuring that the take-up is neat and complete. Secondly, when the partition 9 moves, it will drive the conversion component to move the cutting blade 11, ensuring that the cutting blade 11 moves at the same degree as the partition 9, and ensuring that the cutting blade 11 moves accurately to the corresponding position to cut and divide the fabric.

[0032] The conversion assembly includes a sleeve 12 disposed between the partition 9 and the plug 8. A cylinder 13 is mounted on the main body 1 to drive the sleeve 12. A pull rope 14 is connected to the sleeve 12. A drive wheel 15, connected to the pull rope 14 and used for winding the pull rope 14, is rotatably connected to the main body 1. The drive wheel 15 is horizontally positioned with its axis facing the support roller 10. A connecting rod 16 is engaged in the middle of the drive wheel 15. A bevel gear 17 is engaged at the end of the connecting rod 16 away from the drive wheel 15. A threaded rod 18 is rotatably connected to the main body 1, and the threaded rod 18 is located at the upper end of the cutting blade 11. The cutting blade 11 and the threaded rod 18 are connected to the threaded rod 18. A fixing block 19 is provided between the rods 18. The threaded rod 18 is threadedly connected to the fixing block 19. The threaded rod 18 is provided with a bevel gear 20 that meshes with the bevel gear 17. After being pushed by the cylinder 13 through the partition 9, it will simultaneously pull the pull rope 14, causing the pull rope 14 to pull the winding drive wheel 15 to rotate. This causes the drive wheel 15 to compress the internal spring 21, causing the spring 21 to deform. Finally, when the drive wheel 15 rotates, it will drive the locking connecting rod 16 to rotate. At the same time, the bevel gear 17 at the other end of the connecting rod 16 will be driven to rotate synchronously, and will also drive the meshing bevel gear 20 to rotate, thereby making... The second bevel gear 20 drives the threaded rod 18 to rotate. It is threadedly connected to the threaded rod 18 via a fixing block 19, which is also slidably connected to the main body 1 of the equipment. This allows the fixing block 19 to move inward along the thread of the threaded rod 18, thus moving the cutting blade 11. The thread diameter of the fixing block 19 and the threaded rod 18 is set according to the length of movement of the partition 9. The thread gap width is pre-set as needed. For example, if the partition 9 moves three centimeters, the pull rope 14 will pull three centimeters, and the transmission wheel 15 will rotate half a turn. The diameter of the second bevel gear 20 will decrease, and the gear teeth... The number of rotations is reduced to ensure that the threaded rod 18 rotates a sufficient number of times with a 3-centimeter movement, and that the fixed block 19 also moves a length of 3 centimeters. This ensures that the cutting blade 11 and the partition 9 move along the same path. This setup ensures that after the partition 9 is attached to the large tube of the take-up roller, the cutting blade 11 also moves to the position where the edge of the fabric needs to be cut and is opposite to the partition 9, thus ensuring that the cutting width is sufficient before cutting. This adjustment is quick and simple, and maintenance can be carried out by opening a mold or purchasing a threaded rod 18 of the corresponding size for combination and matching. It is simple and convenient, reduces costs, is quick and simple, and is precise and synchronized without the need for manual adjustment.

[0033] A high-elasticity spring 21 is provided between the transmission wheel 15 and the main body 1 of the equipment to push the transmission wheel 15 to reset. The high-elasticity spring 21 ensures that the transmission wheel 15 is compressed when the pull rope 14 pulls it to rotate. When the cylinder 13 is depressurized and the internal spring pushes it to reset, the tension in the spring 21 disappears, the spring 21 is released and reset, and drives the transmission wheel 15 to reverse and reset. This drives the connecting rod 16 and the bevel gear 17 to reset. The bevel gear 17 drives the meshing bevel gear 20 to reset and simultaneously drives the threaded rod 18 to reverse and reset. This pushes the fixing block 19 backward and resets it, ensuring that the cutting blade 11 also resets synchronously. After the new winding roller 3 is placed or a new size needs to be cut, it can be installed and adjusted synchronously again.

[0034] The adjusting assembly includes an abutment block 22 slidably connected to the sleeve 12 and used to push the insert 8 to move. The abutment block 22 is located at the end of the insert 8, and the end of the insert 8 has a groove 38 for receiving the abutment block 22. A spring 23 is provided between the abutment block 22 and the sleeve 12 to push the abutment block 22. The elastic force of the spring 23 is greater than the weight of the insert 8. The abutment surface between the abutment block 22 and the groove 38 of the insert 8 is inclined. The insert 8 is provided with a connecting assembly connected to the take-up roller 3. After the cylinder 13 is opened by the switch 35, it moves through the piston rod to push the sleeve 12, so that the abutment block 22 on the sleeve 12 pushes the insert 8 synchronously, so that the smaller diameter end of the insert 8 is directly embedded into the take-up roller 3. The sleeve 12 continues to move until the part with the larger diameter of the plug 8 is in contact with the take-up roller, thus preventing further movement. At this point, the combined force of the thrust of the cylinder 13 and the blocking force of the take-up roller 3 causes the sleeve 12 to continue moving. The thrust causes the abutment block 22 to be compressed inward along the inclined surface of the groove 38, and the internal spring 23 is compressed, thereby canceling the blocking connection and allowing the sleeve 12 to move forward on its own. This causes the partition 9 to be in contact with the side of the take-up roller 3. Thus, by pushing the cylinder 13, the connection between the plug 8 and the take-up roller 3 can be guaranteed, and then the automatic switching is performed so that the partition 9 can continue to move without being blocked by the plug 8, and the partition 9 can block and restrict the winding of the fabric.

[0035] The connecting assembly includes a protrusion 24 rotatably connected to the front end of the plug-in 8 at the position where it is embedded in the take-up roller 3. The middle of the protrusion 24 is rotatably connected to the plug-in 8. At the end of the protrusion 24 away from the take-up roller 3, there is a pressing block 25 that is slidably connected to the plug-in 8. The pressing block 25 is pressed down by the moved sleeve 12. A torsion spring 26 is provided at the rotatable connection between the protrusion 24 and the plug-in 8 to push the protrusion 24 back to its original position. The plug-in 8 has a stepped cross-section for embedding. Inside the take-up roller 3, there is a retainer at the position opposite to the protrusion 24 to accommodate and press the protrusion 24 into place. The slot 27, and the position with the larger diameter of the insert 8, is in contact with the take-up roller 3. After the sleeve 12 is pushed by the piston of the cylinder 13, it will move along the position with the larger diameter of the insert 8, and abut against the extrusion block 25 that protrudes from the insert 8, and push it downward, so that the extrusion block 25 pushes the protrusion 24 downward, so that the protrusion 24 rotates along the middle rotation point, and compresses the internal torsion spring 26. The protrusion 24, located at the position where the insert 8 is embedded in the take-up roller 3, is pushed and moves upward, thereby moving the protrusion 24 away from the extrusion block 25. The device is lifted and embedded into the slot 27, where multiple protrusions 24 create a clamping effect. The friction between them ensures a connection, guaranteeing that the rotation of shaft 6 and shaft 7 drives the insert 8, which in turn drives the take-up roller. Textures or rubber can be provided on the protrusions 24 to increase friction and tighten the connection, ensuring synchronous rotation and preventing the sleeve 12 from separating from the insert 8. The sleeve 12 is long enough to consistently press against the extrusion block 25, maintaining the clamping force on the protrusions 24 and ensuring a tight connection. When disassembly is required, the cylinder 13 resets, pulling the sleeve 12 and partition 9 backwards. After passing the compression block 25, the push on the compression block 25 is released. The torsion spring 26 inside the protrusion 24 drives the protrusion 24 to reset, and the compression block 25 moves downward. At the same time, the clamping connection is released, and the sleeve 12 moves the abutment block 22 to the groove 38. After the abutment block 22 is pushed back into the groove 38 by the spring, the sleeve 12 continues to move backward, which can drive the plug 8 to reset and release the support and connection to the take-up roller 3. This design makes installation and disassembly convenient, quick, and simple, avoiding inconvenience caused by excessive complexity, and eliminating the need for excessive manual operation.

[0036] The main body 1 of the equipment has supports 28 on both the front and rear sides of the threaded rod 18. The fixed block 19 is slidably connected to the supports 28. A push roller 29 for pushing and clamping the fabric is provided on one side of the cutting blade 11. The fixed block 19 is provided with a cylinder 30 for pushing the cutting blade 11 and the push roller 29 downward. The push roller 29 moves downward and abuts against the support roller 10. The slidable connection between the fixed block 19 and the supports 28 ensures the stable movement of the fixed block 19. Under the constraint of the supports 28, the rotation of the threaded rod 18 is ensured by the engagement of the external thread with the internal thread of the fixed block 19, pushing the fixed block 19 to move rather than rotate. In addition, when the fixed block 19 moves, it will drive the cutting blade 11 and the push roller 29 synchronously, and the push roller 29 is inside, thus ensuring the cutting. After the blade 11 is aligned with the fabric, the switch 35 on the main body of the equipment activates the control cylinder 30 to push the cutting blade 11 and the pushing roller 29 downwards. This ensures that the pushing roller 29 is contacting the fabric being wound by the winding roller 3, rather than the edge being cut. At the same time, as the cutting blade 11 and the pushing roller 29 move downwards, the pushing roller 29 and the support roller 10 come into contact with and clamp the fabric. After the fabric is pulled, the pushing roller 29 and the support roller 10 rotate, which also pulls the fabric to make it straighten again. The cutting blade 11 and the pushing roller 29 are staggered to ensure that the cutting blade 11 cuts under the pull of the pushing roller 29 and the support roller 10, so that the fabric is straightened under the pulling force, reducing wrinkles and avoiding cutting deviations. On the other side of the cutting blade 11, there is an abutment roller 31 for pushing the cut edge fabric. The abutment roller 31 is longer than the cutting blade 11 and the pushing roller 29, and the abutment roller 31 is embedded downwards. The main body 1 of the equipment is provided with a take-up roller 32 for winding up the edge material at the lower end of the support roller 10. The surface of the abutment roller 31 has a Velcro hook, and the surface of the take-up roller 32 has adhesive. The abutment roller 31 is also driven synchronously by the fixing block 19, and when the cylinder 30 pushes, it also drives the abutment roller 31 to move downwards. Since the length of the abutment roller 31 is longer than the cutting blade 11, when the lowered cutting blade 11 moves to the position of cutting the fabric, the abutment roller 31 will pull the cut edge fabric downwards, thereby ensuring that the cut edge fabric can also be taut and straight. After adjusting the above-mentioned device during normal cutting, the fabric is pulled to the cutting blade 11 to cut a portion. The required fabric is then connected to the take-up roller 3. The machine is then started so that the abutment roller 31 pushes the edge to connect with the take-up roller 32. The abutment roller 31 pulls the fabric to ensure it is tighter. The abutment roller 31, push roller 29, and cutting blade 11 are distributed as follows: from a top view, the push roller 29 is located at the support roller 10, the cutting blade 11 is at the front, and the abutment roller 31 is located in the middle. The cutting blade 11 is close to the fabric of the main body 1 of the equipment, while the push roller 29 and abutment roller 31 are set on both sides. The fabric on both sides is pulled and tightened by the cutting blade 11 to cut better and ensure a flatter and more stable cut.

[0037] A spring 33 is installed between the abutting roller 31 and the piston of cylinder 30, and a spring 34 is installed between the support plate 5 and the main body 1. As the fabric is wound up by the take-up roller 31 and its weight increases, the support plate 5 is continuously pressed downwards, and the spring 34 is compressed, preventing the support plate 5 from affecting the winding of the fabric. Since the shaft of the take-up roller 31 cannot move, the lower support plate 5 moves downwards continuously, ensuring that the winding thickness can increase rather than be blocked. Furthermore, as the take-up roller 32 continues to wind the fabric, the abutting roller 31 moves upwards due to the increasing thickness. When the push roller moves downward, it drives the second spring 33 and the abutment roller 31 to move downward simultaneously and abut against the second take-up roller 32. The fabric thickness of the second take-up roller 32 increases, and the abutment force increases, pushing the abutment roller 31 to compress the second spring 33 upward. This avoids the situation where the second take-up roller 32 is blocked from taking up. Secondly, the surface of the abutment roller 31 has a Velcro hook surface. By making the hook surface less dense and the hook hardness less, it ensures that when it abuts against the fabric, it only increases the friction force and reduces the restraining force to prevent the fabric from being caught by the hook surface when rotating and taking up. Alternatively, it can be replaced with rubber depending on the actual situation.

[0038] The main body 1 of the equipment is equipped with several switches 35 controlling cylinder 13, drive motor 2, and cylinder 2 30. A stop switch 36 is located at the contact point between the piston of cylinder 13 and sleeve 12 to stop air intake into cylinder 13. A compression spring 37 is installed between the piston of cylinder 13 and sleeve 12, and the spring force of the compression spring 37 is greater than the weight of sleeve 12, partition 9, and insert 8. The main body 1 has multiple switches 35 to control cylinder 13, drive motor 2, and cylinder 2 30 respectively. Therefore, manual control by the operator is possible during use, compared to using sensors. Automatic control with sensors and other devices is used for starting. Although this setting is not fully automatic, it is more convenient to maintain. It only requires circuit connection through existing switches. Then, after the cylinder 13 pushes the sleeve 12 and the partition 9 to move and adhere to the take-up roller 3, the cylinder 13 continues to push, squeezing the compression spring 37 between them. This causes the compression spring 37 to deform, and the protruding part at the bottom of the sleeve 12 can be pressed by the stop switch 36 at the outer end of the piston rod of the cylinder 13. This causes the stop switch 36 to control the cylinder 13 and stop the air intake, so that the cylinder 13 keeps pushing the partition 9 to adhere to the take-up roller 3, thereby ensuring stability.
