Description

A production and cutting device for polypropylene film for high flatness capacitors

Technical Field

The invention relates to the technical field of film production and cutting, in particular to a production and cutting device for a polypropylene film for a high-flat capacitor.

Background Art

Polypropylene film is generally a multi-layer co-extruded film, which is made by co-extruding polypropylene particles into sheets and then stretching them in both the vertical and horizontal directions. Due to the orientation of the stretched molecules, this film has good physical stability, mechanical strength, and air tightness, high transparency and glossiness, and is tough and wear-resistant. It is a widely used printing film. Polypropylene film capacitors are inductive structures, using polypropylene as the dielectric and aluminum foil as the electrode. The conductor is tinned copper-clad steel wire and encapsulated with epoxy resin, so polypropylene film will be used in capacitors.

In this regard, China's patent application number: CN110640802B discloses a polyurethane film cutting device, whose structure includes a frame, a reel, a bracket, a motor, a feed roller group, a cutting device, a receiving roller group, a receiving table, a controller, and a speed regulator. A bracket is welded on the side of the frame, the reel is installed on the bracket, the cutting device is installed in the middle of the frame, and the left and right sides of the cutting device are respectively installed with a feed roller group and a receiving roller group. The feed roller group is connected to the motor by transmission, the motor is electrically connected to the speed regulator, and the speed regulator is electrically connected to the controller. The cutting device includes a cylinder, a cutting knife, an opening, a workbench, and a grinding device. The beneficial effects of the present invention are: the film is pulled by the pressure strips on both sides, which can make the cutting smoother and neater, and prevent rasping and tailing. The grinding wheels arranged in an upper and lower offset manner can grind the cutting knife after each cutting, so that the cutting knife remains sharp, and the blade can be cleaned to avoid residue, thereby improving the cutting effect and ensuring product quality.

However, during actual cutting, due to the large opening, the design of the pressure strip can only flatten the film far away from the opening. Therefore, the film at the edge of the opening has no limit and will move. In addition, when the cutter cuts down at the opening, the film cannot be cut smoothly due to its toughness, and the cutter may also cause the film to deform, making it impossible to cut the film quickly and smoothly. At the same time, the position of the grinding wheel at the lower end is fixed, and the grinding wheel will also affect the stable downward movement of the cutter. Therefore, there are certain limitations when cutting the entire film. Therefore, it has become an urgent problem to be solved to improve and perfect the above-mentioned problems.

When in use, the polypropylene film is firstly wound on the surface of the unwinding frame and then conveyed by the first conveyor belt. When conveyed to the surface of the first conveyor belt, it is adjusted to a suitable size and then the cylinder body is started to drive the cutter body to move downward. When the cutter body moves downward, the stabilizing frame also moves downward. A slit is provided between the first conveyor belt and the support frame. Then the telescopic cylinder and the telescopic column inside the stabilizing frame also move downward as a whole. Then the pressing plate first contacts the polypropylene film before and after the slit. Since a spring body is provided inside the telescopic cylinder, the telescopic column and the pressing plate are more stable when pressed downward, and the polypropylene film at the edge of the slit can be limited to avoid During subsequent cutting, the polypropylene film will move, and the overall limiting effect is good. At the same time, it can also avoid the phenomenon that the polypropylene film will rebound after subsequent cutting. Subsequently, when the pressure plate contacts the polypropylene film for a period of time, the telescopic column will squeeze the spring body inside the stable frame, so that the telescopic column and the pressure plate will move upward, and then the pressure plate will drive the first rack plate to rise. At this time, the first rack plate will drive the first gear column to rotate, so that the first gear column will drive the movable gear to rotate, and then the movable gear will engage with the second rack plate. At this time, the second rack plate will move downward, and then the second rack plate will squeeze the mounting frame downward. Since the mounting frame is limited by two sets of stable frames, the mounting frame will move downward, so that the pressure strip body will contact the polypropylene film away from the slit. The overall flattening and limiting effect on the polypropylene film is good, and the polypropylene film at the slit and away from the slit can be limited before cutting, which is convenient for subsequent cutting operations and reflects the functionality of the design.

The production and cutting device of polypropylene film for high-flat capacitors is provided with a horizontal block, a downward pressure rack plate, a second gear column, a second limiting frame, an upward rack plate, a connecting column, a supporting bar, a side pressure block, a first fixed plate, a second fixed plate, a spring rotating shaft and a grinding column body. When in use, when the cutter body moves downward, the cutter body will drive the horizontal block to descend, and then the horizontal block will contact the top surface of the downward pressure rack plate after descending for a period of time, thereby driving the downward pressure rack plate to descend, and then the downward pressure rack plate will mesh with the second gear column, so that the second gear column will rotate, and the second gear column can be fixed and installed through the second limiting frame, and at the same time, the rotation of the second gear column will drive the upward pressure rack plate to rotate. The lifting rack plate moves, so that the lifting rack plate will move upward. When the lifting rack plate moves upward, the lifting rack plate will drive the connecting column to move upward, and then the connecting column will drive the supporting bar to move upward as a whole. Since the horizontal block and the pressing rack plate are both provided with two groups, the supporting bar can be stably lifted up through the two groups of connecting columns. When the supporting bar rises, the positions of the supporting bar and the cutter body are mutually horizontal. The supporting bar and the cutter body are both installed at the upper and lower ends of the cutting seam. Therefore, when the polypropylene film is subsequently cut, the supporting bar can support the polypropylene film, and then the cutter body can cut it, so that the polypropylene film is cut smoothly and the polypropylene film will not be damaged. The gear wheel is rotated to move the two-way screw rod to rotate, and the movable frame on the surface of the two-way screw rod moves toward the back, so that the movable frame drives the push frame to move toward the back, so that the push frame contacts the spring shaft, and the spring shaft drives the frosted column body to rotate at an angle, so that the back of the frosted column body contacts the front of the cutter body, so that the frosted column body can also be used to grind the cutter body. The cutter body is polished, and the overall use effect is good. Since the first fixed plate and the second fixed plate have the same structure, another set of frosted column bodies on the top surface of the first fixed plate will also fit to the back of the cutter body, so that the front and back surfaces of the cutter body can be polished and cleaned at the same time, so that the overall processing effect is good. This design changes the frosted column body into an adjustable type, so as to avoid a certain obstruction to the cutter body during subsequent cutting. In addition, this design lifts the support bar while the cutter body moves downward, providing a certain support force for the cutting of polypropylene film, and the cutter body also has a polishing and cleaning effect during cutting. The overall use effect is good, which reflects the ingenuity of the design.

A limited position seat 43 is provided on the right surface of the movable frame 41. The first fixed plate 34 and the second fixed plate 35 have the same structure and are installed in symmetrical positions. A spring body is provided inside the telescopic cylinder 14. First, the polypropylene film will be wound on the surface of the unwinding frame 3, and then through the first The conveyor belt 7 is used for conveying. When conveying to the surface of the first conveyor belt 7, it is adjusted to a suitable size, and then the cylinder body 11 is started to drive the cutter body 12 to move downward. When the cutter body 12 moves downward, the stabilizing frame 13 will also move downward. A slit is provided between the first conveyor belt 7 and the support frame 8. Then the telescopic cylinder 14 and the telescopic column 15 inside the stabilizing frame 13 will also move downward as a whole. Then the pressing plate 16 will first contact the polypropylene film before and after the slit. Since a spring body is provided inside the telescopic cylinder 14, the telescopic column 15 and the pressing plate 16 are more stable when pressed downward, and the polypropylene film at the edge of the slit can be limited to prevent the polypropylene film from moving during subsequent cutting. The overall limiting effect is good, and the phenomenon that the subsequent polypropylene film will rebound after cutting can also be avoided. Then, after the pressing plate 16 contacts the polypropylene film for a period of time, the telescopic column 15 will squeeze the spring body inside the stabilizing frame 13, thereby the telescopic column 1 5 and the pressing plate 16 will move upward, and then the pressing plate 16 will drive the first rack plate 22 to rise, at this time the first rack plate 22 will drive the first gear column 21 to rotate, so that the first gear column 21 will drive the movable gear 23 to rotate, and then the movable gear 23 will mesh with the second rack plate 24, at this time the second rack plate 24 will move downward, and then the second rack plate 24 will press the mounting frame 18 downward, because the mounting frame 18 is limited by the two sets of stabilizing frames 17, so that the mounting frame 18 will move downward, so that the pressure strip body 19 will contact the polypropylene film away from the cutting seam, the overall flattening and limiting effect on the polypropylene film is good, and the polypropylene film at the cutting seam and away from the cutting seam can be limited before cutting, so as to facilitate the subsequent cutting operation, when the cutter body 12 moves downward, at this time the cutter body 12 will drive the horizontal block 26 to descend, and then the horizontal block 26 will contact the top surface of the downward pressure rack plate 27 after descending for a period of time, so as to drive the downward pressure rack plate 27 to move downward. The pressing rack plate 27 descends, and then the pressing rack plate 27 will mesh with the second gear column 28, so that the second gear column 28 will rotate, and the second gear column 28 can be fixed and installed through the second limiting frame 29. At the same time, after the second gear column 28 rotates, it will drive the rising rack plate 30 to move, so that the rising rack plate 30 will move upward. When the rising rack plate 30 moves upward, the rising rack plate 30 will drive the connecting column 31 to move upward, and then the connecting column 31 will drive the supporting bar 32 to move upward as a whole. Since the horizontal block 26 and the pressing rack plate 27 are both provided with two groups, the supporting bar 32 can be stably raised by the two groups of connecting columns 31. When the supporting bar 32 rises, the positions of the supporting bar 32 and the cutter body 12 are mutually horizontal. The supporting bar 32 and the cutter body 12 are both installed at the upper and lower ends of the cutting seam, so that when the polypropylene film is subsequently cut, the supporting bar 32 can support the polypropylene film, and then cut it through the cutter body 12, so as to achieve the effect of the cutting effect. The polypropylene film is cut smoothly, the polypropylene film will not be deformed, and the overall cutting effect is good. When the lower pressure rack plate 27 descends, it will drive the side pressure block 33 to descend as a whole, and then the side pressure block 33 will contact the moving rack plate 40, so that the moving rack plate 40 will move downward, and then the moving rack plate 40 will mesh with the rotating gear 39, and then the rotating gear 39 will rotate. Due to the rotation of the rotating gear 39, the rotating gear 39 will drive the bidirectional screw rod 38 to rotate, and the movable frame 41 on the surface of the bidirectional screw rod 38 will move toward the back, so that the movable frame 41 will drive the pushing frame 42 to move toward the back, so that the pushing frame 42 will contact the spring shaft 36, so that the spring shaft 36 will drive the frosting column body 37 to rotate at an angle, so that the back of the frosting column body 37 will contact the front of the cutter body 12, so that the cutter body 12 can also be polished by the frosting column body 37, and the overall use effect is good. 5, so that another group of grinding column bodies 37 on the top surface of the first fixed plate 34 will also be attached to the back of the cutter body 12, so that the front and rear surfaces of the cutter body 12 can be polished and cleaned at the same time, so that the overall processing effect is better.

At the same time, the front and rear sides of the cutter body 12 are both provided with a pressing plate 16 and a pressure strip body 19, so that the polypropylene film at the edge of the slit between the first conveyor belt 7 and the support frame 8 can be limited and fixed. Similarly, two groups of grinding column bodies 37 are also provided. When the cutter body 12 descends, the grinding column body 37 will contact the cutter body 12 to polish and clean the cutter body 12.

Working principle: When the staff uses this device, first connect the device to an external power supply to provide power support for the device. First, the polypropylene film will be wound on the surface of the unwinding rack 3, and then transported through the first conveyor belt 7. When it is transported to the surface of the first conveyor belt 7, it is adjusted to a suitable size, and then the cylinder body 11 is started to drive the cutter body 12 to move downward. When the cutter body 12 moves downward, the stabilizing frame 13 will also move downward. A slit is provided between the first conveyor belt 7 and the support frame 8. Then the telescopic cylinder 14 and the telescopic column 15 inside the stabilizing frame 13 will also move downward as a whole. Then the pressing plate 16 will first contact the polypropylene film before and after the slit. Since a spring body is provided inside the telescopic cylinder 14, the telescopic column 15 and The pressing plate 16 is more stable when it is pressed downward. Then, when the pressing plate 16 contacts the polypropylene film for a period of time, the telescopic column 15 will squeeze the spring body inside the stabilizing frame 13, so that the telescopic column 15 and the pressing plate 16 will move upward, and then the pressing plate 16 will drive the first rack plate 22 to rise. At this time, the first rack plate 22 will drive the first gear column 21 to rotate, so that the first gear column 21 will drive the movable gear 23 to rotate, and then the movable gear 23 will mesh with the second rack plate 24. At this time, the second rack plate 24 will move downward, and then the second rack plate 24 will press the mounting frame 18 downward. Since the mounting frame 18 is limited by the two sets of stabilizing frames 17, the mounting frame 18 will move downward, so that the pressure strip body 19 will contact the polypropylene film away from the slit;

When the cutter body 12 moves downward, the cutter body 12 will drive the horizontal block 26 to descend, and then the horizontal block 26 will contact the top surface of the pressing rack plate 27 after descending for a period of time, thereby driving the pressing rack plate 27 to descend, and then the pressing rack plate 27 will mesh with the second gear column 28, so that the second gear column 28 will rotate, and the second gear column 28 can be fixed and installed through the second limiting frame 29, and at the same time, after the second gear column 28 rotates, it will drive the rising rack plate 30 to move, so that the rising rack plate 30 will move upward, and when the rising rack plate 30 moves upward, the rising rack plate 30 will drive the connecting column 31 to move upward, and then The rear connecting column 31 will drive the supporting bar 32 to move upward as a whole. Since the horizontal block 26 and the lower pressure rack plate 27 are both provided with two groups, the supporting bar 32 can be stably raised by the two groups of connecting columns 31. When the supporting bar 32 rises, the positions of the supporting bar 32 and the cutter body 12 are mutually horizontal. The supporting bar 32 and the cutter body 12 are both installed at the upper and lower ends of the cutting seam. Therefore, when the polypropylene film is subsequently cut, the supporting bar 32 can support the polypropylene film, and then the cutting is performed through the cutter body 12. Therefore, the polypropylene film is cut more smoothly and the polypropylene film will not be deformed. When the lower pressure rack plate 27 descends, it will drive the side pressure block 33 The whole body descends, and then the side pressure block 33 will contact the moving rack plate 40, so that the moving rack plate 40 will move downward, and then the moving rack plate 40 will mesh with the rotating gear 39, and then the rotating gear 39 will rotate. As the rotating gear 39 rotates, the rotating gear 39 will drive the bidirectional screw rod 38 to rotate, and the movable frame 41 on the surface of the bidirectional screw rod 38 will move toward the back, so that the movable frame 41 will drive the pushing frame 42 to move toward the back, so that the pushing frame 42 will contact the spring shaft 36, so that the spring shaft 36 will drive the grinding column body 37 to rotate at an angle, so that the back of the grinding column body 37 will contact the front of the cutter body 12, Therefore, the cutter body 12 can also be polished by the frosting column body 37. Since the first fixing plate 34 and the second fixing plate 35 have the same structure, another set of frosting column bodies 37 on the top surface of the first fixing plate 34 will also be attached to the back of the cutter body 12, so that the front and back surfaces of the cutter body 12 can be polished and cleaned at the same time. The present design changes the frosting column body 37 into an adjustable type, thereby avoiding a certain obstruction to the cutter body 12 during subsequent cutting. In addition, the present design lifts the support bar 32 while the cutter body 12 moves downward, thereby providing a certain support force for the cutting of the polypropylene film. The above is all the working principles of the present invention.
