Description
Technical Field
[0001] This utility model relates to the field of cold cutting equipment technology, and in particular to a cold cutting device for producing conductive films. Background Technology
[0002] The conductive film cold cutting device is a cutting equipment specifically designed for the production of conductive films. Its core is to use a low-temperature environment in conjunction with mechanical cutting components to complete the precise cutting of conductive films while avoiding the effects of high temperatures. This solves the problems of edge damage and performance degradation of film materials caused by traditional thermal cutting.
[0003] Chinese utility model patent CN219152960U discloses a cold cutting machine for packaging film, comprising: a U-shaped plate, with brackets fixedly installed at the center of the outer surfaces of both sides of the U-shaped plate, and grooves opened on the opposite surfaces of the two brackets. A reciprocating screw is movably embedded in the inner cavity of one groove, and a motor is fixedly installed at the top end of the reciprocating screw. A mounting plate is fixedly embedded at the center of the motor and is fixedly installed on the outer surface of the top of the bracket. A guide rod is fixedly embedded in the inner cavity of the other groove, and a horizontal plate is movably fitted on the outer surfaces of the guide rod and the reciprocating screw. A cooling water tank is fixedly installed on the outer surface of the horizontal plate near the bottom, and a blade is fixedly installed on the outer surface of the cooling water tank near the bottom.
[0004] When using the above-mentioned packaging film cold cutting machine to cut conductive film, the conductive film was not effectively fixed near the blade. During the cutting process, the conductive film was subjected to pressure from the blade, which easily caused the conductive film on both sides of the blade to shift relative to the blade edge, thus affecting the cutting quality of the conductive film to some extent. Utility Model Content
[0005] To address the aforementioned problems, this invention provides a cold-cutting device for producing conductive films.
[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a cold cutting device for producing conductive film, comprising a feeding rack and a unloading rack located on one side of the feeding rack, a feeding conveyor belt being arranged between the frame bodies on both sides of the feeding rack, and a unloading conveyor belt being arranged between the frame bodies on both sides of the unloading rack, a driving component for driving the feeding conveyor belt and the unloading conveyor belt to move synchronously being jointly provided on the feeding rack and the unloading rack, a fixing block being fixedly installed between the feeding rack and the unloading rack, two fixing blocks being provided and symmetrically distributed on both sides of the feeding rack, a placement block being fixedly fixed on the top of the two fixing blocks, a cutting component for cutting conductive film being provided on the top of the placement block, and a clamping component for clamping conductive film being provided on the fixing block, two sets of clamping components being provided and symmetrically distributed on both sides of the placement block.
[0007] By adopting the above technical solution, a marker rod is installed on the top of the unloading rack, and scale lines are installed on one side of the rack to help workers determine the distance between the end of the conductive film and the cutting component. Under the action of the drive component, the conductive film is fed from the loading conveyor belt to the unloading conveyor belt. When the distance between the end of the conductive film and the cutting component meets the required length, cutting is required. At this point, the worker needs to use the drive component to shut off the drive of both the loading and unloading conveyor belts and clamp the conductive film using the clamping component. Then, the worker can cut the conductive film using the cutting component. This application changes the phenomenon of relative displacement that easily occurs when the blade cuts the conductive film in traditional technology, thus improving the cutting quality of the conductive film to a certain extent.
[0008] Furthermore, the clamping assembly includes a C-shaped mounting plate fixed to the top of the fixing block, a bidirectional lead screw rotatably mounted on the C-shaped mounting plate and vertically arranged, a pressure bar sleeved on the bidirectional lead screw and threadedly connected to the bidirectional lead screw, and a drive motor fixed to the top of the C-shaped mounting plate for driving the bidirectional lead screw to rotate. The bidirectional lead screw is provided with two sections of threads with equal pitch and opposite directions of rotation. Two pressure bars are provided and symmetrically distributed on the two sections of threads of the bidirectional lead screw. The bidirectional lead screw passes through the side of the C-shaped mounting plate near the drive motor and is fixed to the output end of the drive motor. Each clamping assembly has two C-shaped mounting plates provided and symmetrically distributed on both sides of the loading rack. A slide bar parallel to the bidirectional lead screw is fixed on the C-shaped mounting plate away from the drive motor. The slide bar passes through the pressure bar and slides with the pressure bar.
[0009] By adopting the above technical solution, when it is necessary to use the clamping assembly to clamp the conductive film, the operator only needs to start the drive motor. The drive motor drives the bidirectional lead screw to rotate. Since the bidirectional lead screw is threadedly connected to the pressure bar, the slide bar and the pressure bar slide together, so that the two pressure bars move closer to each other until the conductive film is clamped, ensuring the cutting quality of the conductive film by the cutting assembly. After the cutting is completed, the operator can control the drive motor to make the two pressure bars slide away from each other, releasing the clamping of the conductive film. Then, the drive assembly can drive the conductive film to move from the loading conveyor belt to the unloading conveyor belt.
[0010] Furthermore, the drive assembly includes a transmission unit, which includes a first drive roller rotatably mounted between the two sides of the loading frame and a first driven roller rotatably mounted between the two sides of the loading frame. The roller surfaces of the first drive roller and the first driven roller are both in contact with the inner surface of the loading conveyor belt. The first drive roller and the first driven roller both pass through one side of the loading frame and are rotatably connected. The transmission unit also includes a first synchronous pulley fixedly sleeved on the first drive roller, a second synchronous pulley fixedly sleeved on the first driven roller, and a first synchronous belt meshing with both the first and second synchronous pulleys. The transmission unit also includes a drive motor fixed to the side wall of the loading frame and driving the central rod of the first drive roller to rotate. The drive assembly also includes a linkage unit for driving the unloading conveyor belt and the loading conveyor belt to rotate synchronously.
[0011] By adopting the above technical solution, after the drive motor works, it drives the first active roller and the first synchronous wheel fixed to the first active roller to rotate. The second synchronous wheel and the first driven roller rotate synchronously with the first synchronous wheel under the action of the first synchronous belt, so that the feeding conveyor belt runs. The unloading conveyor belt rotates synchronously with the feeding conveyor belt under the linkage of the linkage unit, thereby realizing the transfer of the conductive film from the feeding conveyor belt to the unloading conveyor belt.
[0012] Furthermore, the linkage unit includes a second active roller rotatably mounted between the two sides of the unloading frame and a second driven roller rotatably mounted between the two sides of the unloading frame. The roller surfaces of the second active roller and the second driven roller are both pressed against the inner surface of the unloading conveyor belt. The second active roller and the second driven roller both pass through one side of the unloading frame and are rotatably connected. The second active roller is located near the drive motor. The linkage unit also includes a third synchronous pulley fixedly sleeved on the second active roller, a fourth synchronous pulley fixedly sleeved on the second driven roller, a second synchronous belt meshing with both the third and fourth synchronous pulleys, a main synchronous pulley fixedly sleeved on the first active roller, a driven synchronous pulley fixedly sleeved on the second active roller, and a third synchronous belt meshing with both the main and driven synchronous pulleys. The drive assembly also includes a synchronization unit for assisting the movement of the conductive film.
[0013] By adopting the above technical solution, when the drive motor operates and drives the first active roller, the rotation of the first active roller drives the main synchronous pulley fixed to it, the third synchronous belt meshing with the main synchronous pulley, and the driven synchronous pulley meshing with the third synchronous belt to rotate. This causes the driven synchronous pulley to drive the second active roller to rotate, and the second active roller drives the fixed third synchronous pulley, the second synchronous belt meshing with the third synchronous pulley, and the fourth synchronous pulley meshing with the second synchronous belt to rotate. This achieves synchronous movement of the unloading conveyor belt and the loading conveyor belt. Under the action of the synchronization unit, the conductive film that needs to be cut later is easily transported to the unloading conveyor belt.
[0014] Furthermore, the synchronization unit includes a first gear fixedly sleeved on the first drive roller and a support block fixed on the loading frame. Two support blocks are provided and symmetrically distributed on both sides of the loading frame. The synchronization unit also includes a first synchronization roller rotatably installed between the two support blocks. The end of the first synchronization roller near the drive motor passes through the support block and is rotatably connected. The synchronization unit also includes a second gear fixedly sleeved on the first synchronization roller and meshing with the first gear, and a third gear fixedly sleeved on the second drive roller. The synchronization unit also includes a mounting block fixed on the unloading frame. Two mounting blocks are provided and symmetrically distributed on both sides of the unloading frame. The synchronization unit also includes a second synchronization roller rotatably installed between the two mounting blocks. The end of the second synchronization roller near the drive motor passes through the mounting block and is rotatably connected. The synchronization unit also includes a fourth gear fixedly sleeved on the second synchronization roller and meshing with the third gear.
[0015] By adopting the above technical solution, when the cut conductive film needs to be conveyed to the unloading conveyor belt, the operator starts the drive motor. The drive motor drives the first active roller fixed to it, the first gear fixed to the first active roller, the second gear meshing with the first gear, and the first synchronous roller fixed to the second gear to rotate. This makes the rotation direction of the first synchronous roller opposite to the rotation direction of the feeding conveyor belt. At the same time, the main synchronous wheel drives the third synchronous belt meshing with it and the driven synchronous wheel meshing with the third synchronous belt to rotate. This makes the driven synchronous wheel drive the second active roller to rotate. The second active roller drives the third gear fixed to it, the fourth gear meshing with the third gear, and the second synchronous roller fixed to the fourth gear to rotate. This makes the rotation direction of the second synchronous roller opposite to the rotation direction of the unloading conveyor belt. When the cut conductive film is conveyed from the feeding conveyor belt to the unloading conveyor belt, the rotation of the unloading conveyor belt and the second synchronous roller causes the conductive film to move on the unloading conveyor belt. At the same time, the subsequent conductive film is re-wound between the second synchronous roller and the unloading conveyor belt for a new round of conductive film cutting.
[0016] Furthermore, the feeding rack is equipped with a guide assembly to prevent the conductive film from shifting during transportation. The guide assembly includes positioning blocks fixed on the feeding rack, with multiple positioning blocks evenly distributed on both sides of the feeding rack. The guide assembly also includes a bidirectional threaded rod rotatably mounted between the multiple positioning blocks, a push plate sleeved on the bidirectional threaded rod and threadedly connected to it, a positioning rod fixed between the multiple positioning blocks and parallel to the bidirectional threaded rod, and a power motor fixed to the side wall of the positioning block and driving the bidirectional threaded rod to rotate. The bidirectional threaded rod has two sections of threads with equal pitch and opposite directions of rotation. Two push plates are provided and symmetrically distributed on the two sections of threads of the bidirectional threaded rod. The bidirectional threaded rod passes through the positioning block near the power motor and is fixed to the output end of the power motor. The positioning rod passes through the push plate and slides with it. The bottom of both push plates abuts against the top of the feeding conveyor belt.
[0017] By adopting the above technical solution, when the size of the conductive film to be conveyed is smaller than the width of the feeding conveyor belt and the unloading conveyor belt, the operator starts the power motor. The power motor drives the bidirectional threaded rod to rotate. Since the bidirectional threaded rod is threadedly connected to the push plate, and the positioning rod is slidably engaged with the push plate, the push plates move towards each other. When the two push plates move to match the width of the conductive film, the operator can turn off the power motor, which reduces the probability of the feeding conveyor belt deviating when conveying the conductive film.
[0018] Furthermore, the cutting assembly includes a U-shaped mounting bracket fixed to the top of the placement block, a U-shaped seat fixed to the top of the U-shaped mounting bracket, a lead screw that passes through and is rotatably connected to the horizontal section of the U-shaped seat, a rectangular frame that is slidably disposed in the U-shaped mounting bracket and threadedly connected to the lead screw, and an active motor fixed to the top of the U-shaped seat and driving the lead screw to rotate. The lower end of the lead screw passes through the U-shaped mounting bracket with clearance fit, and the lower end of the lead screw passes through the rectangular frame and is threadedly connected to the rectangular frame. A cutting edge for cutting the conductive film is fixed at the bottom of the rectangular frame, and a through groove corresponding to the position of the cutting edge is provided on the placement block.
[0019] By adopting the above technical solution, when the operator needs to cut the conductive film conveyed between the feeding conveyor belt and the unloading conveyor belt, the conductive film can first be clamped by the clamping assembly to prevent displacement. Then, the active motor is started, and the active motor drives the lead screw to rotate. Since the rectangular frame is threadedly connected to the lead screw, the rectangular frame abuts against the inner walls on both sides of the U-shaped mounting bracket, thereby realizing that the lead screw drives the rectangular frame to move downward. When the blade fixed under the rectangular frame is inserted into the through groove, the cutting of the conductive film is completed.
[0020] Furthermore, a first pallet is fixed between the two sides of the loading rack, the top of the first pallet being flush with the top of the loading conveyor belt; a second pallet is fixed between the two sides of the unloading rack, the top of the second pallet being flush with the top of the unloading conveyor belt; and the sides of the first and second pallets that are close to each other abut against the sides of the two pressure strips that are far apart from each other.
[0021] By adopting the above technical solution, the setting of the first pallet and the second pallet prevents the end of the conductive film from getting stuck in the gap between the feeding conveyor belt and the unloading conveyor belt when the feeding conveyor belt transports the conductive film after it is cut, thus ensuring that the conductive film is transported from the feeding conveyor belt to the unloading conveyor belt according to the preset path.
[0022] Furthermore, a support plate is fixed to the top of the feeding rack. Two support plates are provided and symmetrically distributed on both sides of the feeding rack. Multiple cooling fans for cooling the conductive film are provided between the two support plates.
[0023] By adopting the above technical solution, the cooling fan can quickly cool down the conductive film entering the feeding conveyor belt (before cutting, the conductive film enters the drying process from the conductive film production process for drying, and the temperature is relatively high), ensuring the cutting quality of the conductive film by the subsequent cutting components.
[0024] In summary, this utility model has the following beneficial effects: A scale rod is provided on the top of the unloading rack, and graduation lines are provided on one side of the rack to facilitate the worker's judgment of the distance between the end of the conductive film and the cutting component. Under the action of the drive component, the conductive film is fed from the loading conveyor belt to the unloading conveyor belt. When the distance between the end of the conductive film and the cutting component meets the required length of the conductive film, cutting is required. At this time, the worker needs to use the drive component to turn off the drive of the loading and unloading conveyor belts, and clamp the conductive film using the clamping component. Then, the worker can cut the conductive film using the cutting component. This application changes the phenomenon of relative displacement that easily occurs when the blade cuts the conductive film in traditional technology, thus improving the cutting quality of the conductive film to a certain extent.

The first drive roller 311 drives the first gear 331, the second gear 334 meshing with the first gear 331, and the first synchronous roller 333 fixed to the second gear 334 to rotate, thereby realizing that the rotation direction of the first synchronous roller 333 is opposite to the rotation direction of the loading conveyor belt 11. Simultaneously, the main synchronous pulley 326 drives the third synchronous belt 328 meshing with it, and the fourth synchronous pulley 324 meshing with the third synchronous belt 325 to rotate. The driven synchronous pulley 327, engaged with 328, rotates, causing the driven synchronous pulley 327 to drive the second active roller 321 to rotate. The second active roller 321 drives the third gear 335 fixed to it, the fourth gear 338 meshing with the third gear 335, and the second synchronous roller 337 fixed to the fourth gear 338 to rotate. This ensures that the rotation direction of the second synchronous roller 337 is opposite to the rotation direction of the unloading conveyor belt 21, thereby allowing the conductive film to be transported by the loading conveyor belt 11 to the unloading conveyor belt 21. When the distance between the ends of the conductive film meets the required length, it needs to be cut. At this time, the operator needs to control the drive motor 316 to shut off the... The feeding conveyor belt 11 and the unloading conveyor belt 21 are driven by starting the drive motor 54. The drive motor 54 drives the bidirectional lead screw 52 to rotate. Since the bidirectional lead screw 52 is threadedly connected to the pressure bar 53, the slide bar 511 slides with the pressure bar 53, so that the two pressure bars 53 move closer to each other until they clamp the conductive film, ensuring the cutting quality of the conductive film by the cutting component 4. After the cutting is completed, the operator can control the drive motor 54 to make the two pressure bars 53 slide away from each other, releasing the clamping of the conductive film. Then, the drive motor 316 can drive the conductive film to move from the feeding conveyor belt 11 to the unloading conveyor belt 21.
[0034] In this embodiment, the guide assembly 6 is disposed on the loading rack 1 and is used to prevent the conductive film from shifting during transportation. The guide assembly 6 includes a positioning block 61, a bidirectional threaded rod 62, a push plate 63, a positioning rod 64, and a power motor 65. The positioning block 61 is fixed on the loading rack 1, and multiple positioning blocks 61 are disposed and evenly distributed on both sides of the loading rack 1. The bidirectional threaded rod 62 is rotatably mounted between multiple positioning blocks 61, and the bidirectional threaded rod 62 is provided with two sections of threads with equal pitch and opposite directions. The push plate 63 is sleeved on the bidirectional threaded rod 62 and threadedly connected to the bidirectional threaded rod 62. Two push plates 63 are disposed and symmetrically distributed on the two sections of threads of the bidirectional threaded rod 62, and the bottom of both push plates 63 abuts against the top of the loading conveyor belt 11. The positioning rod 64 is fixed between multiple positioning blocks 61 and parallel to the bidirectional threaded rod 62. The positioning rod 64 passes through the push plate 63 and slides with the push plate 63. A power motor 65 is fixed to the side wall of the positioning block 61 and drives the bidirectional threaded rod 62 to rotate. The output axis of the power motor 65 coincides with the axis of the bidirectional threaded rod 62. In this embodiment, the bidirectional threaded rod 62 passes through the positioning block 61 near the power motor 65 and is fixed to the output end of the power motor 65.
[0035] When the size of the conductive film to be conveyed is smaller than the width of the feeding conveyor belt 11 and the unloading conveyor belt 21, the operator starts the power motor 65. The power motor 65 drives the bidirectional threaded rod 62 to rotate. Since the bidirectional threaded rod 62 is threadedly connected to the push plate 63, and the positioning rod 64 is slidably engaged with the push plate 63, the push plates 63 move towards each other. When the two push plates 63 move to match the width of the conductive film, the operator can turn off the power motor 65, which reduces the probability of the feeding conveyor belt 11 deviating when conveying the conductive film.
[0036] In this embodiment, a first pallet 12 is fixed between the two sides of the loading rack 1, and the top of the first pallet 12 is flush with the top of the loading conveyor belt 11. A second pallet 13 is fixed between the two sides of the unloading rack 2, and the top of the second pallet 13 is flush with the top of the unloading conveyor belt 21. The sides of the second pallet 13 that are close to the first pallet 12 respectively abut against the sides of the two pressure strips 53 that are far from each other. The arrangement of the first pallet 12 and the second pallet 13 prevents the end of the conductive film from getting stuck in the gap between the loading conveyor belt 11 and the unloading conveyor belt 21 when the conductive film is transported by the loading conveyor belt 11 after it has been cut, ensuring that the conductive film is transported from the loading conveyor belt 11 to the unloading conveyor belt 21 according to a preset path.
[0037] In this embodiment, a support plate 14 is fixed to the top of the loading rack 1. Two support plates 14 are provided and symmetrically distributed on both sides of the loading rack 1. A cooling fan 15 is provided between the two support plates 14. Multiple cooling fans 15 are provided and used to cool the conductive film. A controller (not shown in the figure) is provided on the side wall of the support plate 14. The controller is used to control the switching on and off of the cooling fans 15. The cooling fans 15 can quickly cool the conductive film entering the loading conveyor belt 11 (before cutting, the conductive film enters the drying process from the conductive film production process for drying, and the temperature is relatively high), ensuring the cutting quality of the conductive film by the subsequent cutting assembly 4.
