[0002] Insulating film is a thin film material with insulating properties, which is mainly used in the electrical, electronic, aerospace and automotive fields. Insulating film die-cutting is a process of processing insulating film materials into specific shapes and sizes. The principle of circular knife die-cutting is that the material is deformed under the pressure of the tool and separated into the required shape to achieve processing purposes such as cutting and turning.

[0003] At present, when using a circular knife die-cutting device, there is a lack of an automatic synchronous tensioning mechanism. Usually, during the circular knife die-cutting process of the insulating film, the conveying mechanism is prone to slipping, resulting in a decrease in the stability of the insulating film conveying, which not only affects the conveying efficiency, but also affects the quality of the circular knife die-cutting, thereby affecting the use effect of the device. Therefore, an insulating film circular knife die-cutting device is proposed to increase an automatic synchronous tensioning mechanism. While the die-cutting mechanism of the die-cutting device is working, the synchronous tensioning of the insulating film is achieved by connecting rod driving, sliding displacement, and jacking support.

[0042] The synchronous tensioning assembly 3 includes a rotating disk 301, and the mounting frame 1 installs the rotating disk 301 through a bearing. The surface of the rotating disk 301 is connected to a curved rod 302 through bolts. The middle section of the curved rod 302 is sleeved and connected to a rotating frame 303. A tensioning roller 304 is rotatably installed in the rotating frame 303 through a bearing.

[0043] When in use, a synchronous auxiliary tensioning mechanism can be added by installing the frame 1, the rotating disk 301, the curved rod 302, the rotating frame 303 and the tensioning roller 304. The rotating disk 301 and the curved rod 302 are rotated to drive the rotating frame 303 to rotate, so that the tensioning roller 304 slides back and forth up and down, thereby achieving the effect of auxiliary support and lifting, and performing auxiliary tensioning on the insulating film during the transportation process. This can not only improve the stability of the insulating film transportation, but also cooperate with the circular knife die-cutting component 2 to perform die-cutting processing, thereby improving the die-cutting effect of the device. The structure is simple and compact, the cost is low, and the use is more reasonable and flexible, thereby improving the use effect of the device.

[0044] For example, Figure 3 , Figure 5 As shown, the present invention also includes that the back of the rotating frame 301 is connected to a guide rod 305 by bolts, one end of the guide rod 305 is connected to a limiting slider 306 by bolts, a limiting groove 101 is provided on the surface of the mounting frame 1, and the limiting slider 306 is slidably connected to the limiting groove 101, and the outer surface of the rotating disk 301 is fixedly sleeved with a rack 307.

[0045] When in use, the limiting slider 306 of the guide rod 305 is limited and slidably connected to the limiting groove 101, so that the displacement of the tensioning roller 304 can be limited, so that the sliding connection and the curved rod connecting rod mechanism can be used to drive the tensioning roller 304 to move vertically back and forth, and the insulating film in the die-cutting and conveying process can be lifted and supported, thereby achieving the effect of intermittent auxiliary tensioning, improving the stability of the insulating film conveying, and improving the die-cutting quality of the insulating film.

[0046] For example, Figure 2 As shown, the present invention also includes that the circular knife die-cutting component 2 includes a fixed frame 201, and the mounting frame 1 is fixedly connected to the fixed frame 201 by bolts, the surface of the fixed frame 201 is horizontally mounted with a conveying roller 202 through a bearing, the surface of the fixed frame 201 is located at the top of the conveying roller 202 and a corresponding cutting roller 203 is horizontally mounted through a bearing, and the surface of the fixed frame 201 is located at the bottom of the conveying roller 202 and is rotatably connected with a cleaning component 4.

[0047] When in use, the fixed frame 201 is used to rotate and connect the conveying roller 202 and the cutting roller 203, and the conveying roller 202 and the cutting roller 203 can be used to perform circular die cutting processing on the conveyed and displaced insulating film by utilizing the relative rotation of the conveying roller 202 and the cutting roller 203.

[0048] For example, Figure 4 As shown, the present invention also includes that the cleaning component 4 includes a rotating roller 401, one side of the rotating roller 401 is connected to a fan-shaped frame 402 by bolts, the outer surface of the fan-shaped frame 402 is provided with bristles 403 corresponding to the conveying roller 202, and the other side of the fan-shaped frame 402 is connected to a pressure plate 404 corresponding to the curved rod 302 by bolts.

[0049] When in use, by rotating the rotating disk 301, when the curved rod 302 rotates to the side of the cleaning component 4, the pressure plate 404 can be pressed downward, driving the rotating roller 401 and the fan-shaped frame 402 to rotate upward, and the bristles 403 are in contact with the surface of the bottom of the conveying roller 202 to clean and remove debris, and the insulating film waste adhered to the surface is brushed off and recycled, thereby achieving a synchronous cleaning effect. The structure is simple and easy to operate, and the use is more stable and reliable.

[0050] For example, Figure 4 As shown, the present invention also includes that the back of the rotating roller 401 is connected with a rotating shaft 405 by bolts, and the rotating roller 401 is rotatably connected to the fixed frame 201 through the rotating shaft 405, and the outer periphery of the rotating shaft 405 is provided with a coil spring 406, and one end of the coil spring 406 is connected to the rotating shaft 405 by welding, and the other end of the coil spring 406 is connected to the fixed frame 201 through a slot.

[0051] When in use, the rotating roller 401 can be rotated to connect to the fixed frame 201 through the rotating shaft 405 and the coil spring 406, so that after the rotating roller 401 of the cleaning component 4 rotates and completes the cleaning process of the bottom surface of the conveying roller 202, the elastic deformation is used to drive the rotating shaft 405 to reverse and reset.

[0052] For example, Figure 2 As shown, the present invention also includes that a driving gear 204 is rotatably connected to the fixed frame 201 through a rotating shaft, and the driving gear 204 is meshedly connected to the rack 307 through a reserved opening, the top of the driving gear 204 is meshedly connected to a driving gear 205, and the driving gear 205 is connected to one end of the conveying roller 202 through bolts, and the top of the driving gear 205 is meshedly connected to a driven gear 206, and the driven gear 206 is fixedly connected to one end of the cutting roller 203 through bolts.

[0053] When in use, the driving gear 204 is used to drive the active gear 205 and the driven gear 206 to rotate, thereby driving the conveying roller 202 and the cutting roller 203 to rotate relative to each other for die-cutting processing. At the same time, through the meshing connection rack 307, the rotating disk 301 of the synchronous tensioning assembly 3 is driven to rotate to perform synchronous intermittent tensioning. The structure is simple, the cost is low, and the maintenance cost is low.

[0054] For example, Figure 5 As shown, the present invention also includes that a discharge roller 5 is installed on the surface of the fixed frame 1 at one side of the synchronous tensioning assembly 3 through a bearing, a first guide roller 501 is installed on the surface of the fixed frame 1 at the bottom of the discharge roller 5 through a bearing, a winding roller 6 is installed on the surface of the fixed frame 1 away from the discharge roller 5 through a bearing, and a second guide roller 601 is installed on the surface of the fixed frame 1 at the bottom of the winding roller 6 through a bearing.

[0055] When in use, the discharge roller 5 and the first guide roller 501 can be used to guide the insulating film to between the conveying roller 202 and the cutting roller 203 of the circular die-cutting assembly 2 for circular die-cutting processing. The winding roller 6 and the second guide roller 601 can be used to guide the insulating film for recycling processing by rotating winding after the circular die-cutting processing is completed, so that the operator can remove the waste material.

[0056] For example, Figure 5 As shown, the present invention also includes that a first conveyor belt 7 is horizontally arranged on the surface of the fixed frame 1 at the bottom of the second guide roller 601 of the winding roller 6, and a second conveyor belt 8 is horizontally arranged on the surface of the fixed frame 1 at the bottom of the first conveyor belt 7.

[0057] When in use, the first conveyor belt 7 is convenient for receiving the insulating film products that fall after circular knife die-cutting and transporting them horizontally, and the second conveyor belt 8 is convenient for receiving the insulating film products sent out by the first conveyor belt 7 and transporting them to the outside, which plays an effect of assisting material unloading and improves the convenience of subsequent operators in recovering materials.

[0058] For example, Figure 6 As shown, the present invention also includes that the back of the fixed frame 1 is connected to the driving motor 104 by bolts, and the driving motor 104 is connected to the driving gear 204 by a driving shaft, and the back of the fixed frame 1 is located on one side of the driving motor 104 and is connected to the winding motor 105 by bolts, and the winding motor 105 is connected to the winding roller 6 by a driving shaft.

[0059] When in use, the driving motor 104 is used to drive the driving gear 204, so that the driving gear 204 drives the conveying roller 202 to start conveying the insulating film for die-cutting processing. The winding motor 105 is used to synchronously drive the winding roller 6 to rotate, driving the insulating film after die-cutting to be wound and recycled.

[0060] For example, Figure 5 , Figure 6 As shown, the present invention also includes that a slot 102 is provided on the surface of one side of the fixing frame 1, and a clamping strip 103 corresponding to the slot 102 is connected to the other side of the fixing frame 1 by bolts, and a mounting plate 106 is connected to the bottom of the back of the fixing frame 1 by welding, and a mounting hole 107 is provided on the surface of the mounting plate 106.

[0061] When in use, through the provided card slots 102 and card strips 103, the flexibility of the device combination use can be increased by utilizing the methods of plug-in limiting and splicing combination, thereby forming multiple circular knife die-cutting processing stations through modular design to meet different processing needs, and through the mounting plate 106 and the mounting hole 107, it is convenient to pre-fix the fixing frame 1 with bolts to improve the stability of the device use.

[0062] For example, Figure 7 As shown, the present invention also includes that a recovery component 9 is horizontally arranged on one side of the bottom of the fixed frame 1, the recovery component 9 includes a recovery frame 901, and the fixed frame 1 is connected to the recovery frame 901 by bolts, a recovery groove 902 is opened in the recovery frame 901, and a guide plate 903 is arranged in the recovery groove 902.

[0063] When in use, the recycling rack 901 and the recycling trough 902 can assist in the recycling of the fallen insulating film waste, thereby reducing the pollution to the inside of the device and the working environment, and facilitating the subsequent operators to perform cleaning operations. The guide plate 903 can facilitate the transportation of the recovered insulating film to the outside, thereby improving the convenience of the subsequent operators' regular cleaning operations. The structure is simple and the use is more reasonable and reliable. The recycling trough 902 is connected to the guide plate 903 through the damping shaft rotation.

[0064] When the present invention is in use, firstly, the driving motor 104 and the winding motor 105 are manually turned on, and the insulating film on the unwinding roller 5 passes through the first guide roller 501 and enters between the conveying roller 202 and the cutting roller 203 of the circular knife die-cutting assembly 2, and the driving motor 104 drives the driving gear 204 to rotate, and drives the driving gear 205 to rotate relatively through the meshing connection, and the driving gear 205 drives the driven gear 206 to rotate relatively, and the driving gear 205 drives the conveying roller 202 and the driven gear 206 drives the cutting roller 203 to rotate relatively, and the passing insulating film is subjected to the circular knife die-cutting processing action, and the insulating film product after die-cutting begins to fall on the first conveyor belt 7 under the action of its own weight, and the first conveyor belt 7 is manually turned on, and the insulating film product is transported to the top of the second conveyor belt 8 and falls, and then the second conveyor belt 8 is manually turned on, and the insulating film product after die-cutting is transported to the outside to complete the discharge, and the insulating film after die-cutting is guided by the second guide roller 601 to the winding roller 6, and is wound and recycled by the rotation of the winding roller 6;

[0065] During the die-cutting process of the insulating film, the driving gear 205 rotates, and the meshing rack 307 is used to drive the rotating disk 301 and the curved rod 302 to rotate. At the same time, the rotating frame 303 sleeved on the periphery of the middle section rotates with the curved rod 302. Since its end is restricted by the vertical sliding of the guide rod 305 and the limit slider 306, the tensioning roller 304 can slide up and down while the insulating film is being die-cut by the circular knife. Through the sliding displacement and lifting support of the tensioning roller 304, the insulating film can be intermittently tensioned during the conveying process, thereby improving the stability of the insulating film conveying, making it less susceptible to displacement due to factors such as slipping, and improving the accuracy of its die-cutting process. The structure is simple and easy to operate, and the use is more stable and reliable, and it is also beneficial to improve the die-cutting quality of the insulating film.

[0066] When the synchronous tensioning assembly 3 follows the synchronous tensioning action of the driving mechanism, the curved rod 302 rotates with the rotating disk 301. When the curved rod 302 rotates to one side of the cleaning assembly 4, the pressing plate 404 begins to turn over under the downward pressure of the curved rod 302, and the rotating roller 401 drives the fan-shaped frame 402 to start turning upward, so that the bristles 403 contact the bottom surface of the conveying roller 202 after die-cutting, and perform auxiliary cleaning on the residual insulating film waste adhered to it, so that the insulating film waste falls into the recycling frame 901 of the recycling assembly 9, and is recycled by the recycling groove 902, and is guided to the outside by the guide plate 903, so that the subsequent operators can clean it regularly. The structure is simple, the cost is low, and the use is more stable and reliable. In addition, through the synchronous cleaning method, it can also avoid the residual and accumulation of waste on the surface of the conveying roller 202, thereby improving the stability of insulating film feeding and die-cutting, and improving the accuracy of die-cutting processing depth, and the practical value is high.

[0067] According to actual use needs, multiple groups of mounting frames 1 can be placed horizontally in advance, the card strips 103 can be inserted into the corresponding adjacent mounting frame 1 limit grooves 101, and then the mounting frames 1 can be fixed and connected by bolts to facilitate the use of modular design to increase the flexibility of the device. Multiple insulating film circular knife die-cutting processing stations can be formed to adapt to a variety of different production and processing needs. The use is more flexible and reliable, and the actual practical value is higher.
