Description

Technical Field

[0001] This utility model relates to the field of plastic sheet processing technology, and in particular to a die-cutting machine for processing insulating plastic sheets. Background Technology

[0002] In modern industrial production, insulating plastic sheets are widely used in many fields such as electronics, aerospace, and automobile manufacturing due to their good insulation properties, mechanical strength, and corrosion resistance. As the core equipment for achieving precise cutting and shaping in the processing of insulating plastic sheets, the processing efficiency and quality directly affect the production cycle and final quality of the products.

[0003] In the die-cutting process of insulating plastic sheets, waste is inevitably generated when processing the plastic sheets into rolls due to the characteristics of the production process. At present, although some die-cutting machines on the market are equipped with waste collection devices, these devices have some drawbacks in actual use. After the waste is collected, it is often necessary to manually disassemble the waste collection parts in order to remove the waste. This not only increases the workload of operators and reduces production efficiency, but also the frequent manual disassembly operations can easily lead to wear and tear on the equipment parts.

[0004] Meanwhile, in terms of die-cutting part collection, most existing die-cutting machines use a simple method of placing collection boxes to receive the cut die-cut parts. As the processing continues, the die-cut parts will accumulate in the collection boxes. If the accumulated die-cut parts are not processed in time, it will not only affect the normal feeding of subsequent die-cut parts and cause production interruption, but also cause damage such as compression deformation when the accumulation height is too high, affecting product quality, increasing scrap rate, and thus causing material waste and increased production costs.

[0005] Therefore, it is necessary to provide a new die-cutting machine for processing insulating plastic sheets to solve the above-mentioned technical problems. Utility Model Content

[0006] To solve the above-mentioned technical problems, this utility model provides a die-cutting machine for processing insulating plastic sheets.

[0007] The die-cutting machine for processing insulating plastic sheets provided by this utility model includes: a die-cutting machine body, a collecting roller, a winding assembly, a collecting box, and a driving assembly. A conveying roller is installed on one side of the die-cutting machine body, a top material rod is provided above the conveying roller, and a support frame is installed below the conveying roller. A collecting roller for collecting waste material is provided above the end of the conveying roller near the unloading end. A winding assembly is installed between the collecting roller and the support frame. The winding assembly drives the collecting roller to rotate clockwise to collect waste material and drives the collecting roller to rotate counterclockwise to remove the collected waste material from the collecting roller. A collecting box for collecting the die-cut parts cut by the die-cutting machine body is slidably installed inside the support frame. A driving assembly is installed between the support frame and the collecting box. The driving assembly drives the collecting box to sway between the support frame to level the die-cut parts accumulated inside it.

[0008] Preferably, the winding assembly includes: a motor, a drive gear, a driven gear, a threaded rod, and a slider. The motor is fixedly connected to the top of the support frame away from the conveying roller. A transmission rod is fixedly connected to the output end of the motor. The drive gear is fixedly connected to the other end of the transmission rod. A threaded rod is rotatably connected to the top of the support frame near the transmission rod. A driven gear is fixedly connected to the end of the threaded rod near the drive gear. The drive gear and the driven gear are meshed. A spring is sleeved on the end of the threaded rod near the driven gear. The end of the spring near the driven gear is fixedly connected to the threaded rod. A slider is installed on the threaded rod near the spring. When the threaded rod rotates clockwise, one side of the slider contacts the spring and compresses the spring. The end of the threaded rod away from the driven gear extends into the interior of the collecting roller and is fixedly connected to the inner wall of one end of it.

[0009] Preferably, the outer wall of the threaded rod is symmetrically provided with grooves along its axial direction, and baffles are slidably connected inside each groove. The side wall of the baffle near the slider is rotatably connected to the slider. A limit rod is fixedly connected to the bottom of the slider, and the other end of the limit rod passes through the inside of the support frame and is slidably connected to its inner wall.

[0010] Preferably, the drive assembly includes: a driving pulley, a driven pulley, and a rotating rod. The driving pulley is fixedly connected to one end of the drive rod near the motor. The rotating rod is rotatably connected inside the support frame below the driving pulley. The driven pulley is fixedly connected to one end of the rotating rod. The driving pulley and the driven pulley are connected by a belt drive.

[0011] Preferably, a first connecting rod is fixedly connected to the end of the rotating rod away from the driven pulley, and a second connecting rod is rotatably connected to the side wall of the other end of the first connecting rod. An installation groove is provided on the side wall of one end of the collection box, and a slot corresponding to the installation groove is provided on the other end of the second connecting rod. An insert rod is slidably connected inside the slot, and the other end of the insert rod is inserted into the installation groove.

[0012] Preferably, the outer diameter of the driving pulley is larger than the outer diameter of the driven pulley.

[0014] Compared with related technologies, the die-cutting machine for processing insulating plastic sheets provided by this utility model has the following advantages:

[0015] The automatic collection and removal of waste materials is achieved through a winding assembly. The motor controls the collection roller to wind up the waste material clockwise, and when it rotates counterclockwise, the spring pushes the slider to connect with the threaded rod, which drives the baffle to automatically remove the waste material. This process does not require manual disassembly, reducing the workload of operators, avoiding wear and tear on equipment parts caused by frequent disassembly, extending the service life of the equipment, improving the reliability of the equipment, and significantly improving the efficiency of waste material processing, speeding up the production pace, and reducing labor costs.

[0016] This design of the drive components ensures efficient leveling of stacked modules in the collection box, maintains unobstructed material flow, and avoids production interruptions. Simultaneously, it prevents modules from deforming due to stacking and compression, reducing scrap rates, ensuring product quality, minimizing material waste, and effectively controlling production costs.

It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0023] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0024] Please see Figures 1 to 4 A die-cutting machine for processing insulating plastic sheets includes: a die-cutting machine body 1, a collecting roller 4, a winding assembly, a collecting box 5, and a driving assembly. A conveying roller 2 is mounted on one side of the die-cutting machine body 1. A top material rod is provided above the conveying roller 2, and a support frame 3 is mounted below the conveying roller 2. A collecting roller 4 for collecting waste material is located above the end of the conveying roller 2 near the unloading end. A winding assembly is installed between the collecting roller 4 and the support frame 3. The winding assembly drives the collecting roller 4 to rotate clockwise to collect waste material. The counterclockwise rotation is used to remove the collected waste material from the collecting roller 4. A collecting box 5 for collecting the die-cut parts cut by the die-cutting machine body 1 is slidably installed inside the support frame 3. A drive assembly is installed between the support frame 3 and the collecting box 5. The drive assembly drives the collecting box 5 to swing between the support frames 3 to level the die-cut parts accumulated inside. The winding assembly includes: a motor 6, a drive gear 7, a driven gear 8, a threaded rod 9, and a slider 10. The top of the support frame 3 away from the conveying roller 2 is fixedly connected to the motor 6. The output end of the motor 6 is fixedly connected to a transmission. The other end of the transmission rod is fixedly connected to a drive gear 7. A threaded rod 9 is rotatably connected to the top of the support frame 3 near the transmission rod. A driven gear 8 is fixedly connected to one end of the threaded rod 9 near the drive gear 7. The drive gear 7 and the driven gear 8 are meshed together. A spring 11 is fitted onto one end of the threaded rod 9 near the driven gear 8. The end of the spring 11 near the driven gear 8 is fixedly connected to the threaded rod 9. A slider 10 is installed on the threaded rod 9 near the spring 11. When the threaded rod 9 rotates clockwise, one side of the slider 10 contacts the spring 11. The spring 11 is compressed and the end of the threaded rod 9 away from the driven gear 8 extends into the interior of the collecting roller 4 and is fixedly connected to the inner wall of one end of it. The outer wall of the threaded rod 9 is symmetrically provided with grooves 12 along its axial direction. The interior of each groove 12 is slidably connected with a baffle 13. The side wall of the baffle 13 near the slider 10 is rotatably connected to the slider 10. The bottom of the slider 10 is fixedly connected with a limit rod 14. The other end of the limit rod 14 passes through the interior of the support frame 3 and is slidably connected to its inner wall. The outer wall of the collecting roller 4 is provided with a clearance groove corresponding to the groove 12.

[0025] It should be noted that during the clockwise rotation of the threaded rod 9, the slider 10 is located at the end close to the driven gear 8. At this time, the slider 10 is not connected to the thread on the threaded rod 9, and the spring 11 is in a compressed state. This is to ensure that the slider 10 will not move with the rotation of the threaded rod 9 when the waste material is being wound up.

[0026] Please see Figure 2 and Figure 4The drive assembly includes: a drive pulley 15, a driven pulley 16, and a rotating rod 17. The drive pulley 15 is fixedly connected to one end of the drive rod near the motor 6. The rotating rod 17 is rotatably connected inside the support frame 3 below the drive pulley 15. One end of the rotating rod 17 is fixedly connected to the driven pulley 16. The drive pulley 15 and the driven pulley 16 are connected by a belt drive. A connecting rod 18 is fixedly connected to one end of the rotating rod 17 away from the driven pulley 16. A connecting rod 29 is rotatably connected to the other end of the connecting rod 18. An installation groove is provided on one side wall of the collection box 5. A slot corresponding to the installation groove is provided on the other end of the connecting rod 29. An insert rod 20 is slidably connected inside the slot. The other end of the insert rod 20 is inserted into the installation groove. The outer diameter of the drive pulley 15 is larger than the outer diameter of the driven pulley 16.

[0027] It should be noted that: during waste collection, the drive pulley 15, which is fixed near the motor 6, drives the driven pulley 16, which is installed inside the support frame 3 and located below the drive pulley 15, to rotate via a belt, thereby causing the rotating rod 17 to rotate as well; the other end of the rotating rod 17 is fixed with a connecting rod 18, and the side wall of the other end of the connecting rod 18 is rotatably connected to a connecting rod 19, the other end of the connecting rod 19 has a slot, and a plug rod 20 is slidably connected in the slot, which is inserted into the mounting slot on one side of the collection box 5; therefore, during the rotation of the rotating rod 17, the collection box 5 will slide inside the support frame 3 through the cooperation of the connecting rod 18 and the connecting rod 19; since the outer diameter of the drive pulley 15 is larger than the outer diameter of the driven pulley 16, according to the principle of belt drive, the rotating rod 17 will rotate rapidly, thereby causing the collection box 5 to shake rapidly inside the support frame 3, leveling the modules accumulated inside the collection box 5.

[0028] The working principle of the die-cutting machine for processing insulating plastic sheets provided by this utility model is as follows:

[0029] When the die-cutting machine body 1 is started, it will perform die-cutting operation on the rolled plastic sheet, cutting the plastic sheet into the required mold parts according to the preset shape and size; after the die-cutting is completed, the plastic sheet enters the conveyor roller 2, which is responsible for continuing to convey the plastic sheet forward; the ejector rod installed above the conveyor roller 2 will push the mold parts out of the plastic sheet and make them fall into the collection box 5 below the conveyor roller 2;

[0030] Waste collection stage

[0031] A collecting roller 4 is provided above the end of the conveying roller 2 near the material feeding end. After the operator winds the waste material onto the collecting roller 4, the motor 6 is started. The output end of the motor 6 drives the transmission rod to rotate, and the drive gear 7 at the other end of the transmission rod rotates accordingly. Since the drive gear 7 is meshed with the driven gear 8, the driven gear 8 will drive the threaded rod 9, which is fixedly connected to it, to rotate. Since the end of the threaded rod 9 away from the driven gear 8 extends into the collecting roller 4 and is fixedly connected to it, the collecting roller 4 will rotate clockwise as the threaded rod 9 rotates, thereby performing a winding operation on the waste material.

[0032] During the clockwise rotation of the threaded rod 9, the slider 10 is located at the end close to the driven gear 8. At this time, the slider 10 is not connected to the thread on the threaded rod 9, and the spring 11 is in a compressed state. This is to ensure that the slider 10 will not move with the rotation of the threaded rod 9 when winding up the waste material.

[0033] Module collection and leveling stage

[0034] While the waste is being collected, the drive pulley 15, which is fixed at one end of the transmission rod near the motor 6, will drive the driven pulley 16, which is installed inside the support frame 3 and located below the drive pulley 15, to rotate via a belt, thereby causing the rotating rod 17 to rotate accordingly.

[0035] The other end of the rotating rod 17 is fixed with a connecting rod 18. The side wall of the other end of the connecting rod 18 is rotatably connected to a connecting rod 19. The other end of the connecting rod 19 is provided with a slot, and a plug rod 20 is slidably connected in the slot. The plug rod 20 is inserted into the mounting slot on one side of the collection box 5. Therefore, during the rotation of the rotating rod 17, the cooperation of the connecting rod 18 and the connecting rod 19 will drive the collection box 5 to slide inside the support frame 3.

[0036] Since the outer diameter of the driving pulley 15 is larger than the outer diameter of the driven pulley 16, according to the principle of belt drive, the rotating rod 17 will rotate rapidly, thereby causing the collection box 5 to shake rapidly inside the support frame 3, leveling the mold parts piled up inside the collection box 5, and avoiding the mold parts from piling up too high, affecting subsequent unloading and causing damage to the mold parts.

[0037] Waste removal stage

[0038] After the die-cutting work is completed, the operator starts the motor 6 to reverse; through the meshing of the drive gear 7 and the driven gear 8, the threaded rod 9 rotates counterclockwise; at this time, under the action of the spring force of the spring 11, the spring 11 will push the slider 10 to connect with the thread on the threaded rod 9; since the bottom of the slider 10 is fixed with a limit rod 14, and the other end of the limit rod 14 passes through the support frame 3 and slides through its inner wall, the slider 10 will move along the axial direction of the threaded rod 9;

[0039] Simultaneously, slider 10 pushes baffle 13 to slide within groove 12. As slider 10 moves, the waste material wrapped around collecting roller 4 is gradually removed by baffle 13, thus achieving automatic waste removal, improving work efficiency, reducing manual workload and wear on equipment parts. After removing the waste material, motor 6 is restarted to drive threaded rod 9 to rotate clockwise. At this time, slider 10 moves in the opposite direction along the axial direction of threaded rod 9, and drives baffle 13 to move together for reset. When slider 10 moves to the end of threaded rod 9 and disengages from the thread, spring 11 is compressed in preparation for the next operation.

[0040] When the operator needs to remove the module collected in the collection box 5, simply pull the insert rod 20 in the slot at the other end of the connecting rod 19 to disengage it from the mounting slot on one side of the collection box 5. At this time, the collection box 5 can be pulled out from inside the support frame 3, the module can be collected and put back, and then the insert rod 20 can be inserted into the mounting slot again.

[0041] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
