Detailed Implementation
[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0021] Please see Figure 1 - Figure 5This utility model provides an embodiment: a cutting device for producing plastic woven bags, including a cutting table 1, a support leg 2 at the lower end of the cutting table 1, a surrounding plate 3 fixedly installed on one side of the upper end of the cutting table 1, a guide roller 4 installed inside the surrounding plate 3, the guide roller 4 being configured to guide the plastic woven bag to move along the long side of the cutting table 1; through holes 5 are opened through the inside of the cutting table 1, the through holes 5 being evenly distributed along the short side of the cutting table 1, each through hole 5 being provided with an auxiliary rotating wheel 6, the auxiliary rotating wheel 6 being used to assist the movement of the plastic woven bag; a groove 7 is opened on the surface of the cutting table 1, a limit unit is installed in the groove 7, the limit unit is connected to the guide unit, wherein the limit unit is configured to restrict the lateral movement of the plastic woven bag when it moves. The displacement and guiding unit is configured to work in conjunction with the limiting unit to adjust its position. A pressing unit is located on one side of the limiting unit, configured to press the plastic woven bag into a fixed position before cutting. A cutting unit is located on one side of the pressing unit, featuring a detachable structure and configured to perform the plastic woven bag cutting operation. The cutting table 1 serves as the basic support platform for the entire cutting equipment, providing a stable working surface for the plastic woven bag cutting operation. The enclosure 3 provides installation space for the guide roller 4, which is located within the enclosure 3. When the plastic woven bag enters the cutting equipment, the guide roller 4, through its own rotation, transforms the sliding friction between the plastic woven bag and the guide roller 4 into rolling friction, significantly reducing friction. The reduced friction allows the woven plastic bag to move more smoothly along the long side of the cutting table 1. Simultaneously, the rotation direction and arrangement of the guide rollers 4 ensure that the woven plastic bag is conveyed in the predetermined direction, guaranteeing cutting accuracy. The auxiliary roller 6 operates based on the principle of rolling friction. When the woven plastic bag moves on the cutting table 1, the auxiliary roller 6 contacts the bag and rotates accordingly. The presence of the auxiliary roller 6 reduces the friction between the woven plastic bag and the surface of the cutting table 1, making the bag move more easily. The limiting unit restricts the lateral displacement of the woven plastic bag during its movement. When the woven plastic bag moves on the cutting table 1, the limiting unit can adjust the position according to the woven plastic bag's movement. The width of the woven bag is precisely adjusted to fit tightly against the edge of the plastic woven bag, thus preventing the plastic woven bag from shifting in the lateral direction and ensuring that the plastic woven bag maintains the correct position during the cutting process, guaranteeing the accuracy of the cutting dimensions. The pressing unit is used to press the plastic woven bag into a fixed position before cutting. Before the cutting operation begins, the plastic woven bag is pressed onto the cutting table 1. The cutting unit is used to perform the cutting operation of the plastic woven bag. The detachable structure design allows the cutting blade 28 to be easily replaced and maintained. When the blade wears out or when it is necessary to cut plastic woven bags of different shapes and sizes, the appropriate blade can be quickly replaced, improving the flexibility and efficiency of the equipment.
[0022] Please see Figure 2In this embodiment, the limiting unit includes a bearing seat 8 disposed on the side wall of the groove 7. A bidirectional lead screw 9 is rotatably connected inside the bearing seat 8. The end of the bidirectional lead screw 9 extends to the outside of the cutting table 1 and is provided with a knob 10. A movable seat 11 is threadedly connected to the outer wall of the bidirectional lead screw 9. A vertical plate 12 is provided at the upper end of the movable seat 11. The surface of the vertical plate 12 has a groove 13 adapted to the edge of the plastic woven bag. The guiding unit includes a slide rail 14 disposed at the bottom of the groove 7. A slider 15 is slidably connected on the slide rail 14. The upper end of the slider 15 is connected to the lower end of the moving seat 11. The bearing seat 8 provides stable rotational support for the bidirectional lead screw 9. Both ends of the bidirectional lead screw 9 are rotatably connected to the bearing seat 8 via bearings. This structure allows the bidirectional lead screw 9 to rotate freely within the bearing seat 8. The end of the bidirectional lead screw 9 extends outside the cutting table 1 and is equipped with a knob 10. The operator can manually control the rotation of the bidirectional lead screw 9 by rotating the knob 10. When the bidirectional lead screw 9 rotates, due to the screws on the bidirectional lead screw 9 in different directions... The textured design and the threaded engagement between the movable seat 11 and the bidirectional lead screw 9 enable the movable seat 11 to move linearly along the axial direction of the bidirectional lead screw 9. A vertical plate 12 is installed at the upper end of the movable seat 11, and the vertical plate 12 moves with the movement of the movable seat 11. When the plastic woven bag moves on the cutting table 1, the vertical plate 12 contacts the edge of the plastic woven bag through the slot 13, which plays a role in limiting the lateral displacement of the plastic woven bag. By rotating the knob 10 to adjust the rotation direction of the bidirectional lead screw 9, the two movable seats 11 can be moved closer or further apart, thereby precisely adjusting the position of the vertical plate 12 according to the different width specifications of the plastic woven bag, ensuring that the plastic woven bag always maintains the correct lateral position during the cutting process, and ensuring the accuracy of the cutting dimensions. The slide rail 14 and the slider 15 provide guidance for the movement of the movable seat 11, ensuring that the movable seat 11 can move stably along a straight line under the drive of the bidirectional lead screw 9, avoiding the movable seat 11 from deviating or shaking during the movement, thereby ensuring the accuracy of the limiting unit in limiting the plastic woven bag.
[0023] Please see Figure 3In this embodiment, the pressing unit includes a bracket 16 mounted on the cutting table 1. A screw 17 is internally threaded onto the bracket 16. A knob 18 is mounted on one end of the screw 17, and a lifting seat 19 is mounted on the other end. A bearing seat 20 is mounted on the surface of the lifting seat 19, and a rotating shaft 21 is rotatably connected within the bearing seat 20. Pressing wheels 22 are equidistantly arranged on the outer wall of the rotating shaft 21. A groove 24 is provided on the side wall of the bracket 16, and a protrusion 23 is integrally provided on the side end of the lifting seat 19. The protrusion 23 is slidably connected to the groove 24. The bracket 16, mounted on the cutting table 1, provides an installation and support platform for the screw 17. By rotating the knob 18 mounted on one end of the screw 17, the screw 17 can rotate within the bracket 16. Due to the threaded engagement between the screw 17 and the bracket 16, when the screw 17 rotates, it will generate a linear displacement along its own axial direction. The other end of the screw 17 is provided with a lifting seat 19. The lifting seat 19 moves up and down with the linear displacement of the screw 17. When the lifting seat 19 moves downward, the pressure roller 22 moves downward as well until it contacts the plastic woven bag and applies a certain pressure. During the cutting process, the pressure roller 22 can press down the plastic woven bag. At the same time, the pressure roller 22 is rotatably connected to the rotating shaft 21. During the conveying of the plastic woven bag, the pressure roller 22 can rotate with the movement of the plastic woven bag, changing the sliding friction into rolling friction, reducing the friction between the plastic woven bag and the pressure roller 22, and reducing the wear of the plastic woven bag. The sliding structure composed of the groove 24 and the protrusion 23 provides a guiding role for the movement of the lifting seat 19, ensuring that the lifting seat 19 can move stably up and down in the vertical direction under the drive of the screw 17, and avoiding the lifting seat 19 from deviating during the movement.
[0024] Please see Figure 4 - Figure 5In this embodiment, the cutting unit includes a gantry 25 mounted on the cutting table 1. A hydraulic cylinder 26 is mounted on the gantry 25. A top plate 27 is mounted on the power output end of the hydraulic cylinder 26. A cutting tool 28 is mounted on the top plate 27. A slot 29 is provided at the lower end of the top plate 27. A locking block 30 adapted to the slot 29 is provided at the upper end of the cutting tool 28. The locking block 30 is inserted into the slot 29. Both the locking block 30 and the slot 29 are provided with matching magnets. The locking block 30 and the slot 29 are magnetically connected. The gantry 25 is mounted on the cutting table 1, providing a mounting base for the hydraulic cylinder 26. Hydraulic cylinder 26 is fixed on gantry 25 and serves as the power drive for cutting tool 28. When hydraulic cylinder 26 receives a control signal, its power output end will generate linear motion, thereby driving top plate 27 to move up and down. Cutting tool 28 is installed on top plate 27. Cutting tool 28 is used to cut plastic woven bags. Locking block 30 is inserted into locking slot 29. This locking structure allows cutting tool 28 to be easily and quickly installed on top plate 27, and also facilitates disassembly when the tool is worn or needs to be replaced with a different specification tool. Locking block 30 and locking slot Each slot 29 is equipped with a matching magnet. The locking block 30 and the locking slot 29 are connected to each other by magnetic force, which enhances the connection stability between the cutting tool 28 and the top plate 27 and prevents the cutting tool 28 from loosening or falling off during the cutting process. When the hydraulic cylinder 26 drives the top plate 27 to move downward, the cutting tool 28 moves downward accordingly and applies cutting force to the plastic woven bag that is pressed by the pressing unit to complete the cutting operation of the plastic woven bag. After the cutting is completed, the hydraulic cylinder 26 drives the top plate 27 to move upward, which lifts the cutting tool 28 to prepare for the next cutting operation.
[0025] Working principle: First, according to the width of the plastic woven bag, the operator rotates knob 10 to control the rotation of the bidirectional lead screw 9, which drives the moving seat 11 to move linearly along the slide rail 14, so that the groove 13 of the vertical plate 12 fits tightly with the edge of the plastic woven bag, restricting its lateral displacement and ensuring the accuracy of the cutting size.
[0026] Next, the operator rotates knob 18 to make screw 17 rotate within bracket 16, which drives lifting seat 19 to move vertically downward along slide 24, causing pressure roller 22 to press the plastic woven bag. Pressure roller 22 rotates with the movement of plastic woven bag, reducing friction and wear.
[0027] Then, the cutting unit starts working. After receiving the control signal, the hydraulic cylinder 26 drives the top plate 27 to move downward, which in turn moves the cutting tool 28 downward. The locking block 30 of the cutting tool 28 is inserted into the locking groove 29 of the top plate 27 and is connected to each other by magnetic force to ensure stability during the cutting process. When the cutting tool 28 contacts the compressed plastic woven bag, it applies cutting force to complete the cutting operation.
[0028] Finally, the hydraulic cylinder 26 drives the top plate 27 to move upward, which in turn lifts the cutting tool 28, preparing for the next cutting operation. At the same time, the operator can adjust the position of the limit unit and the pressing unit as needed to accommodate plastic woven bags of different widths and specifications.
[0029] Through the above steps, the limiting unit precisely adjusts to fit the bag edge, avoiding lateral deviation, ensuring cutting precision, and improving accuracy. The detachable design of the cutting unit facilitates blade replacement and maintenance, enhances equipment flexibility, and solves the problems of fixed guide rollers 4 in traditional equipment, which are not adjustable and easily cause lateral deviation of woven bags, affecting cutting precision, and fixed blade replacement is cumbersome and difficult to adapt to diverse cutting needs.
