Technical Field
[0001] This invention relates to the field of die-cutting technology for insulating products, specifically a mica sheet die-cutting device. Background Technology
[0002] Die-cutting is a crucial step in the production and processing of mica sheets. Typically, a mica sheet die-cutting device is used, employing an upper and lower die to cut the mica sheets to meet the shape and size requirements of different products. However, the die-cutting process generates a large amount of dust, which, if not cleaned promptly, can cause numerous problems: 1. Dust will adhere to the die-cutting surface and die-cutting area, which will change the dimensional accuracy and surface smoothness of the die, resulting in quality problems such as dimensional deviation and uneven edges of the die-cut mica sheets, thus reducing the product qualification rate.
[0003] 2. Dust entering the mechanical parts of the die-cutting device will increase the friction between the parts, accelerate wear, shorten the service life of the equipment, and increase the maintenance cost and downtime of the equipment.
[0004] 3. Dust permeates the working environment. If operators inhale it, it will damage their respiratory tract and lungs, causing occupational diseases and affecting their health.
[0005] Most existing mica sheet die-cutting devices lack effective cleaning mechanisms or have poor cleaning performance, failing to completely remove dust generated in the die-cutting area and thus failing to meet the requirements for product quality, equipment maintenance, and personnel health during production. Therefore, developing a mica sheet die-cutting device that can effectively clean dust in the die-cutting area is of significant practical importance. Summary of the Invention

Dust removal grooves are provided on the opposite end faces of the two dust removal blocks. When the two dust removal blocks are respectively sealed and attached to the die-cutting areas of the upper and lower cutting dies, the dust removal groove and the die-cutting area form a sealed dust removal space. At this time, an airflow channel that is connected to the dust removal space is formed between the end face of the cleaning block and the die-cutting area. When cleaning the die-cutting area, the control component controls two dust removal blocks to seal and adhere to the die-cutting areas of the upper and lower die respectively through the end face of the dust removal slot opening. The circulating air blowing component controls high-speed airflow to enter the airflow channel through the cleaning block. The high-speed airflow carries the dust in the die-cutting area to flow synchronously through the dust removal space, and then flows back to the circulating air blowing component. The circulating air blowing component filters the high-speed airflow carrying dust.

[0010] Preferably, the drive structure includes a drive gear disposed on the driven fan blade, a transmission gear disposed in the cleaning port and meshing with the drive gear, and a rotating ring rotatably disposed in the cleaning port and having a driven gear ring at the bottom of the inner ring meshing with the transmission gear, the end of the rotating ring being connected to a cleaning rod.
[0011] Preferably, the control component includes a movable member connecting two dust removal blocks and a sealing member disposed on the movable member and connecting the two dust removal blocks; when the control component controls the two dust removal blocks to seal and adhere to the die-cutting area, the movable member drives the two parallel dust removal blocks to move to a position between the upper die and the lower die, and the sealing member controls the two dust removal blocks to move away from each other and seal and adhere to the opposite end faces of the upper die and the lower die respectively.
[0012] Preferably, the moving component includes a connecting rod arranged along the moving direction of the two dust removal blocks and one end located between the two dust removal blocks, a telescopic structure vertically arranged on the opposite ends of the two dust removal blocks and connected to the end of the connecting rod, and a moving structure for controlling the connecting rod to move away from the end of the dust removal blocks; when the moving structure drives the connecting rod to the initial state, the two dust removal blocks are located on one side of the upper cutting die and the lower cutting die; when the moving structure drives the connecting rod to the end of the stroke, the moving structure drives the two dust removal blocks to pass between the upper cutting die and the lower cutting die through the connecting rod.
[0013] Preferably, the sealing element includes two control rods symmetrically arranged on both sides of the dust collector block about the connecting rod, multiple sets of linkage structures arranged on the control rods and connecting the two dust collector blocks, an elastic structure arranged on the output end of the moving part and connecting the connecting rod, and a sealing material arranged on the end face of the dust collector block; each set of linkage structures includes a linkage block fixedly arranged on the control rod body, and linkage rods symmetrically arranged about the linkage block, with one end of the two linkage rods rotatably connected to the upper and lower ends of the linkage block, and the other end rotatably connected to the corresponding upper and lower positions of the sides of the two dust collector blocks respectively.
[0014] Preferably, the sealing element further includes a mounting rod horizontally disposed on the side of the two dust collector blocks away from the connecting rod, two vertically disposed on the mounting rod with vertical grooves on the side adjacent to the dust collector blocks, and two limiting blocks that slide through the vertical grooves and are respectively connected to the sides of the two dust collector blocks. The two ends of the mounting rod are movably sleeved on different control rods.
[0015] Preferably, the die-cutting assembly includes a guide post arranged vertically and having an upper die base detachably mounted on its top end, a lower die base movably sleeved on the guide post and located parallel to and below the upper die base, a lifting block located parallel to and below the lower die base and connected to the lower die base, and a lifting component for controlling the reciprocating lifting motion of the lifting block on the guide post; a lower cutting die and an upper cutting die are detachably mounted on the opposite surfaces of the lower die base and the upper die base.

[0017] The beneficial effects of this invention are: 1. During the cleaning of the die-cutting area, the control unit controls two dust collection blocks to seal and adhere to the die-cutting areas of the upper and lower dies, forming a sealed dust collection space. The circulating air blowing unit controls a high-speed airflow to enter the airflow channel through the cleaning blocks, carrying the dust from the die-cutting area synchronously through the dust collection space, and then flowing back to the circulating air blowing unit for filtration.

[0018] 2. The control components are ingeniously designed, controlling the two dust collection blocks to be spaced apart and sealed to the opposite end faces of the upper and lower cutting dies, forming a sealed dust collection space. This sealing design prevents high-speed airflow and dust from leaking into the surrounding environment, ensuring cleaning effectiveness while avoiding dust pollution of the working environment and protecting the health of operators.

[0030] To make the technical means, creative features, achieved objectives, and effects of this invention readily understandable, the invention is further described below with reference to specific embodiments and accompanying drawings. However, the following embodiments are merely preferred embodiments of this invention and not all embodiments. Other embodiments obtained by those skilled in the art based on the embodiments described herein without creative effort are all within the protection scope of this invention.
[0031] In existing mica sheet die-cutting processes, the following methods are mainly used to treat the dust generated during the die-cutting process, but all of them have significant technical defects: The first method involves setting up an air outlet on the die-cutting machine's workbench to spray air onto the die-cutting area. This method can effectively clean the dust in the die-cutting area, but the cleaned dust will be blown directly into the air. On the one hand, this will cause pollution to the working environment, and on the other hand, the dust floating in the air will re-adhere to the die-cutting area, affecting the mica sheet die-cutting process.
[0032] The second method involves installing side-suction hoods around the worktable of the die-cutting equipment. A centrifugal fan then transports dust-laden air through galvanized steel pipes to a pulse-jet baghouse dust collector. The dust collector uses polyester fiber filter bags and employs compressed air pulse backflushing for cleaning. However, this type of side-suction hood, while effective at removing dust from the surrounding environment, has a low capture rate, leading to excessive dust concentrations in the workshop. Furthermore, it cannot clean the surface dust within the die-cutting area. While this method avoids dust pollution in the working environment, it fails to remove dust from the die-cutting area itself.
[0033] The third method involves installing a spray system in the die-cutting area, using a circulating water pump to spray the treatment solution onto the dust-generating points. The dust-laden wastewater is treated in an inclined plate sedimentation tank and then recycled. The settled sludge is dewatered by a plate and frame filter press and then transported off-site for disposal. While this method can effectively clean the surface dust in the die-cutting area compared to the second method, the spraying process can also cause dust to adhere to the die-cutting area after being contaminated with water droplets, resulting in insufficient cleaning. Furthermore, the spraying method can leave residual moisture on the mica sheet surface, reducing interlayer bonding and lowering the product qualification rate after spraying treatment.
[0034] In view of the problems that occur in the die-cutting process of mica sheets in the prior art, the present invention proposes a mica sheet die-cutting device that facilitates the comprehensive and thorough removal of dust generated in the die-cutting area.
[0035] For ease of explanation, the improved basis of this invention will first be introduced as follows, such as... Figures 3-5As shown, the mica sheet die-cutting device mainly includes a device body 1, an upper die holder 3 and a lower die holder 2 arranged parallel to each other on the device body 1, an upper cutting die 6 and a lower cutting die 5 correspondingly arranged on the opposite surfaces of the upper die holder 3 and the lower die holder 2, a die-cutting component arranged inside the device body 1 to control the lower cutting die 5 and the upper cutting die 6 to die-cut the mica sheet, and a dust removal mechanism to clean the dust in the die-cutting area. The upper cutting die 6 and the lower cutting die 5 can be detached and installed on the upper die holder 3 and the lower die holder 2.
[0036] The die-cutting assembly includes a guide post 4 arranged vertically and with an upper die base 3 detachably mounted on its top end; a lower die base 2 movably sleeved on the guide post 4 and located parallel to and below the upper die base 3; a lifting block 43 located parallel to and below the lower die base 2 and connected to the lower die base 2; and a lifting component that controls the reciprocating lifting motion of the lifting block 43 on the guide post 4; a lower cutting die 5 and an upper cutting die 6 are detachably mounted on the opposite surfaces of the lower die base 2 and the upper die base 3.
[0037] The lifting component includes a control wheel 42 that is parallel to and rotatably connected to the lifting block 43 below the lifting block 43, an eccentric wheel that is vertically mounted on the control wheel 42 at one end and located off-center from the end face of the control wheel 42, a drive wheel that is parallel to and mounted below the eccentric wheel and fitted with a conveyor belt, a positioning rod 41 that is rotatably mounted on the eccentric wheel and the drive wheel at both ends, and a power source that controls the drive wheel to rotate.
[0038] The power source consists of a drive motor 37 and a gear transmission structure located inside the device body 1 and connected to the drive wheel. The gear transmission structure includes a first control gear 38 mounted on the output end of the drive motor 37, a second control gear 39 meshing with the first control gear 38, and a third control gear 40 meshing with the second control gear 39, wherein the third control gear 40 is disposed on the end face of the drive wheel.
[0039] The die-cutting process of the mica sheet by this mica sheet die-cutting device is as follows: The drive motor 37 is powered on and operates, transmitting rotational motion to the drive wheel through a gear transmission structure. The drive wheel drives the control wheel 42 to rotate synchronously via a conveyor belt. The eccentric wheel moves in a circular motion around the eccentric wheel along with the control wheel 42. The eccentric wheel converts the rotational motion into the reciprocating linear motion of the lifting block 43 through the positioning rod 41. The accuracy of the motion trajectory is ensured by the straightness of the guide column 4. The lifting block 43 drives the lower die base 2 to move upward along the guide column 4, and the lower cutting die 5 and the upper cutting die 6 gradually close: the cutting edges of the upper and lower cutting dies cut into the mica sheet, completing the die-cutting action; and maintain pressure for 0.5-1 seconds to ensure complete separation of the cut seam and avoid dimensional deviations caused by springback. After the upper and lower cutting dies move away from each other, the dust in the die-cutting area is cleaned by a cleaning mechanism.
[0040] Example 1: Reference Figures 1-5The mica sheet die-cutting device shown includes a device body 1, a die-cutting assembly that controls the upper die 6 and the lower die 5 to die-cut the mica sheet, and a cleaning mechanism disposed on the device body 1 to clean the die-cutting area. The cleaning mechanism includes a control assembly, two dust removal blocks 13 connected to the control assembly, cleaning blocks 14 respectively disposed in two dust removal grooves, and a circulating air blowing assembly connecting the dust removal blocks 13 and the cleaning blocks 14. Dust removal grooves are opened on the opposite end faces of the two dust removal blocks 13.
[0041] When the two dust removal blocks 13 are respectively sealed and attached to the die-cutting areas of the upper die 6 and the lower die 5, the dust removal groove and the die-cutting area form a sealed dust removal space. At this time, an airflow channel is formed between the end face of the cleaning block 14 and the die-cutting area, which is connected to the dust removal space. When the high-speed airflow passes through the airflow channel, it will carry away the dust attached to the surface of the airflow channel, thereby cleaning the die-cutting area.
[0042] When cleaning the die-cutting area, the control component controls two dust removal blocks 13 to be sealed and attached to the die-cutting areas of the upper die 6 and the lower die 5 through the end face of the dust removal groove opening. The circulating air blowing component controls the high-speed airflow to enter the airflow channel through the cleaning block 14. The high-speed airflow carries the dust in the die-cutting area to flow synchronously through the dust removal space, and then flows back to the circulating air blowing component. The circulating air component filters the high-speed airflow with dust.
[0043] In this embodiment, the control component controls two dust removal blocks 13 to be sealed and attached to the opposite surfaces of the upper cutting die 6 and the lower cutting die 5. A high-speed airflow is blown into the airflow channel by a circulating air blowing component. The high-speed airflow carries the dust out through the dust removal tank and flows to the circulating air blowing component for filtration. This facilitates the efficient removal of dust adhering to the surface of the die-cutting area (the die-cutting area between the opposite surfaces of the upper cutting die 6 and the lower cutting die 5), ensuring the continuous and stable operation of the die-cutting work and guaranteeing the product quality of the mica sheet die-cutting. The sealing design prevents dust from spreading into the surrounding environment during the cleaning process, avoiding pollution to the working environment, while also ensuring the cleaning effect. This allows the high-speed airflow to concentrate on the die-cutting area, more effectively removing the dust.
[0044] Example 2: In Example 1, the high-speed airflow is not convenient for cleaning dust with strong adhesion to the die-cutting area. This example provides the following solution.
[0045] like Figure 6 and Figure 8As shown, the cleaning mechanism also includes a linkage dust removal component, which includes a drive component that passes through the cleaning port 27 of the cleaning block 14, a cleaning rod that is mounted on the drive component, and a cleaning brush 22 that is mounted on the cleaning rod. The cleaning block 14 has an air inlet in the middle of one end face that passes through the dust removal groove. When the circulating air blowing component controls the high-speed airflow to enter the airflow channel through the cleaning port 27, the drive component drives the cleaning rod to rotate around the cleaning port 27 axially. The cleaning brush 22 is made of anti-static nylon, which takes into account both wear resistance and softness, and avoids scratching the die-cutting area.
[0046] In this embodiment, when the circulating air blowing assembly controls the high-speed airflow to enter the airflow channel, the driving component drives the cleaning rod to rotate around the cleaning port 27 axially. At this time, the cleaning brush 22 located on the cleaning rod gently touches and sweeps the surface of the die-cutting area to clean the dust on the surface of the die-cutting area. The cleaned dust flows through the dust removal groove to the circulating air blowing assembly along with the high-speed airflow.
[0047] It is understood that the cleaning rod can be controlled to rotate axially around the cleaning port 27 in various ways. This embodiment provides the following solution: like Figure 8 As shown, the driving component includes a driven fan blade 28 that is rotatably disposed within the cleaning port 27, and a driving structure that drives the cleaning rod to rotate by rotating the driven fan blade 28.
[0048] In this embodiment, when the high-speed airflow passes through the cleaning port 27, the high-speed airflow drives the driven fan blade 28 to rotate. The driven fan blade 28 drives the cleaning rod to rotate through the drive structure. By linking with the high-speed airflow, the cleaning rod cleans the dust on the surface of the die-cutting area, avoiding the need to add a drive device to control the rotation of the cleaning rod.
[0049] It is understandable that the rotation of the cleaning rod by the driven fan blade 28 can be achieved in various ways. This embodiment provides the following solution: like Figure 8 As shown, the drive structure includes a drive gear 29 disposed on the driven fan blade 28, a transmission gear disposed in the cleaning port 27 and meshing with the drive gear 29, and a rotating ring 30 rotatably passing through the cleaning port 27 and having a driven gear ring 31 meshing with the transmission gear at the bottom of the inner ring. The end of the rotating ring 30 is connected to the cleaning rod.
[0050] In this embodiment, when the driven fan blade 28 rotates under the action of high-speed airflow, the drive gear 29 set on the driven fan blade 28 rotates synchronously. Through the meshing transmission action between the driven fan blade 28, the transmission gear and the driven gear ring 31, it is convenient to drive the cleaning rod to rotate through the rotating ring 30. When the high-speed airflow passes through, the high-speed airflow and the cleaning brush 22 on the cleaning rod can thoroughly clean the die-cutting area, improving the cleaning effect and cleaning efficiency of the die-cutting area.
[0051] Example 3: Regarding the control component in Example 1 that controls the two dust removal blocks 13 to be sealed and attached to the opposite surfaces of the upper cutting die 6 and the lower cutting die 5, this example provides the following solution.
[0052] like Figure 6 and Figure 7 As shown, the control component includes a movable part connecting two dust removal blocks 13 and a sealing part disposed on the movable part and connecting the two dust removal blocks 13; when the control component controls the two dust removal blocks 13 to be sealed and attached to the die-cutting area, the movable part drives the two parallel dust removal blocks 13 to move to a position between the upper die 6 and the lower die 5, and the sealing part controls the two dust removal blocks 13 to move away from each other and seal and attach to the opposite end faces of the upper die 6 and the lower die 5 respectively.
[0053] In this embodiment, when the die-cutting assembly is in the die-cutting state, the moving part controls the two dust removal blocks 13 to be located in the middle position on one side of the upper die 6 and the lower die 5. After the die-cutting assembly finishes die-cutting, the upper die 6 is located above the lower die 5. The moving part drives the two dust removal blocks 13 to move to the position between the two dust removal blocks 13, and drives the two dust removal blocks 13 to move away from each other through the sealing part, so that the end faces of the two dust removal blocks 13 with dust removal grooves are attached to the opposite end faces of the upper die 6 and the lower die 5, ensuring that the dust removal grooves between the two dust removal blocks 13 and the upper die 6 and the lower die 5 form a sealed cavity, so that the subsequent cleaning mechanism can remove dust from the die-cutting area.
[0054] It is understandable that the movement of the two dust removal blocks 13 to the position between the upper cutting die 6 and the lower cutting die 5 can be achieved in various ways. This embodiment provides the following solution: like Figure 6 and Figure 7As shown, the moving component includes a connecting rod 12 arranged along the moving direction of the two dust removal blocks 13 and with one end located between the two dust removal blocks 13; a telescopic structure vertically arranged on the opposite ends of the two dust removal blocks 13 and connected to the end of the connecting rod 12; and a moving structure for controlling the end of the connecting rod 12 away from the dust removal blocks 13 to move. The moving structure is mounted on a mounting plate 7, which is detachably mounted horizontally on the device body 1. When the moving structure drives the connecting rod 12 to the initial state, the two dust removal blocks 13 are located on one side of the upper cutting die 6 and the lower cutting die 5. When the moving structure drives the connecting rod 12 to the end of the stroke, the moving structure drives the two dust removal blocks 13 to pass between the upper cutting die 6 and the lower cutting die 5 through the connecting rod 12.
[0055] The movable structure in this embodiment includes a movable lead screw 16 passing through a movable groove 15 on the end face of the mounting plate 7, and a movable block 17 arranged vertically and whose bottom end is threadedly connected to the body of the movable lead screw 16. The movable block 17 is connected to the connecting rod 12. By driving the movable lead screw 16 to rotate by a motor, the movable block 17 can be moved along the length of the movable lead screw 16. This facilitates the movement of the two dust removal blocks 13 between the upper cutting die 6 and the lower cutting die 5 via the connecting rod 12. When the movable block 17 is located on the body of the movable lead screw 16 away from the dust removal blocks 13, the two dust removal blocks 13 are located on one side of the upper cutting die 6 and the lower cutting die 5. When the motor drives the movable lead screw 16 to rotate and controls the movable block 17 to move to the other end of the movable lead screw 16, the two dust removal blocks 13 are located between the upper cutting die 6 and the lower cutting die 5.
[0056] The telescopic structure of this embodiment includes two adjacent first telescopic rods 35, one end of which is vertically fixed on one end of the connecting rod 12, and a second telescopic rod 36, which is sleeved on the first telescopic rod 35 and one end of which is vertically fixed on the end of the connecting rod 12.
[0057] It is understandable that the two dust collector blocks 13 can be controlled to move away from each other in various ways. This embodiment provides the following solution: like Figures 6-8As shown, the sealing component includes two control rods 19 symmetrically arranged on both sides of the dust collector block 13 about the connecting rod 12, multiple sets of linkage structures arranged on the control rods 19 and connecting the two dust collector blocks 13, an elastic structure arranged on the output end of the moving part and connected to the connecting rods 12, and sealing material arranged on the end face of the dust collector block 13. The sealing material is silicone laid on the end face of the dust collector block 13 with the dust collection groove opening. Each set of linkage structures includes a linkage block fixedly arranged on the rod body of the control rod 19, and linkage rods 20 symmetrically arranged about the upper and lower parts of the linkage block. One end of the two linkage rods 20 is rotatably connected to the upper and lower ends of the linkage block. The other end is rotatably connected to the upper and lower positions of the sides of the two dust removal blocks 13 respectively; the elastic structure includes a slide seat 9 slidably disposed on the top end face of the mounting plate 7, two guide slides 8 symmetrically disposed about the slide seat 9 and parallel to the moving screw 16, a slide rod 24 that passes through the adjusting groove 23 on the end face of the slide seat 9 parallel to the moving screw 16, an adjusting block 25 that is slidably sleeved on the slide rod 24 and connected to the moving block 17 at its end, and an adjusting spring 26 that is sleeved on the slide rod 24 and connected to the groove wall of the adjusting groove 23 and the adjusting block 25 at both ends respectively. The top of the adjusting block 25 is connected to the moving block 17 through a fixing rod 18.
[0058] In this embodiment, when the motor drives the moving screw 16 to rotate, the moving block 17 moves the slide 9 to the other end of the moving screw 16 via the adjusting block 25. Due to the obstruction of the edge of the mounting plate 7 on the slide 9, it cannot continue to move. At this time, the two dust removal blocks 13 are located between the upper cutting die 6 and the lower cutting die 5. Then, the motor continues to drive the moving screw 16 to rotate. At this time, the moving block 17 continues to move towards the connecting rod 12. Due to the limitation of the position of the slide 9, the moving block 17 drives the adjusting block 25 to move towards the connecting rod 12, compressing the adjusting spring 26 on the slide 24. At this time, when the fixed rod 18 drives the control rod 19 to move synchronously towards the dust removal block 13, it pushes the adjacent end of each set of linkage rods 20 to move towards the other end, pushing the other ends of the two linkage rods 20 away from each other. This makes it easier to control the two dust removal blocks 13 to move away from each other, and makes the two dust removal blocks 13 seal against the opposite end faces of the upper cutting die 6 and the lower cutting die 5 through the end face with the dust removal groove.
[0059] Example 4: Regarding the control of the two dust removal blocks 13 to be far apart from each other and sealed and attached to the opposite surfaces of the upper cutting mold 6 and the lower cutting mold 5 in Example 3, how to ensure that the two dust removal blocks 13 are stably far apart from each other? This example provides the following solution.
[0060] like Figure 8 and Figure 9As shown, the sealing component also includes a mounting rod 21 horizontally disposed on the side of the two dust removal blocks 13 away from the connecting rod 12, two vertically disposed on the mounting rod 21 with vertical grooves 33 on the side adjacent to the dust removal block 13, and two limiting blocks 34 that slide through the vertical grooves 33 and are respectively connected to the sides of the two dust removal blocks 13. The two ends of the mounting rod 21 are movably sleeved on the rods of different control rods 19.
[0061] In this embodiment, when the control rod 19 moves, it drives the two linkage rods 20 in each group to move from one end to the other, causing the two dust removal blocks 13 to move away from each other. At this time, the limiting blocks 34 set on the sides of the two dust removal blocks 13 slide in the vertical groove 33 opened in the body of the limiting rod 32, thereby ensuring that the two dust removal blocks 13 move away from each other stably, so as to ensure that the dust removal blocks 13 are sealed and attached to the opposite surfaces of the upper cutting die 6 and the lower cutting die 5.
