Description

Technical Field

[0001] This utility model relates to a device for electroplating through a composite current collector, belonging to the field of composite current collector technology. Background Technology

[0002] With the rapid development of the new energy industry, lithium batteries, as core energy storage components, are facing increasingly higher demands on the preparation processes of key materials as their performance improves. Composite current collectors, especially composite copper foils, are important functional materials inside lithium batteries, and with their advantages of lightweight, high safety, and low internal resistance, they have become a key direction for optimizing the energy density and cycle life of lithium batteries.

[0003] The industrial manufacturing process of composite copper foil involves three core steps: "base film pretreatment—sputtering of copper seed layer—electroplated thickening." Among these, the electroplated thickening process is crucial in determining the conductivity and structural stability of the composite copper foil. Due to the relatively long length of the electroplating tank (requiring continuous coating growth), the magnetron sputtered copper seed layer needs to penetrate the electroplating tank via a "film-through" method for electroplating to obtain the composite current collector, thus achieving continuous electroplating. To avoid breakage or misalignment due to the thinness and low strength of the substrate when the magnetron film is directly penetrated, the industry commonly uses a "tape-driven film-through" method. The specific process is as follows: first, the tape is pulled from the unwinding end to the rewinding end, completing the "pre-penetration" of the entire electroplating path; then, the tape at the unwinding end is cut and bonded to the end of the magnetron film; finally, through the traction of the rewinding end, the magnetron film is driven to pass through the electroplating tank synchronously with the tape, completing the electroplating process.

[0004] However, the traditional "tape-driven film threading" method has many technical drawbacks in practical applications, which seriously restrict production efficiency and processing quality. Specifically:

[0005] 1. The tape roller is only supported and fixed by a simple bracket. Before each film insertion, the tape roller needs to be manually moved to the bracket, and after the film insertion is completed, it needs to be manually removed and stored. Since the tape roller itself has a certain weight, frequent handling not only consumes manpower, but also easily causes the tape roller to be bumped and damaged due to improper operation, affecting the flatness of the tape.

[0006] 2. The cutting of the tape and the bonding of the composite copper foil are both done manually. When the tape is cut manually with a knife, problems such as uneven cuts and dimensional deviations are likely to occur. When the tape and the magnetron film (both are flexible materials) are aligned and bonded manually, it is difficult to ensure the bonding accuracy and the bonding pressure is uneven. This can lead to "detachment" during the subsequent traction process, requiring the machine to be stopped again for treatment, which seriously affects the continuity of production.

[0007] 3. The randomness of manual operation (such as cutting force, bonding angle, pressing strength, etc.) leads to inconsistent tape cutting accuracy and bonding quality each time the film is threaded, which in turn causes the magnetron sputtering film to shift, wrinkle or even break, affecting the uniformity of the electroplated layer and ultimately causing fluctuations in product yield. Utility Model Content

[0008] To solve the above-mentioned technical problems, this utility model provides a device for electroplating through composite current collectors.

[0009] The technical solution adopted by this utility model to solve its technical problem is:

[0010] A composite current collector electroplating film-piercing device includes: a base; a lifting assembly is provided on one side of the top of the base; a storage assembly is provided on the lifting assembly; a tape roller is detachably mounted on the storage assembly via a fixing assembly; an unwinding roller is provided on one side of the storage assembly for unwinding magnetron sputtering film; a gantry frame fixedly mounted to the base is provided on the side of the unwinding roller away from the lifting assembly; a cutting mechanism for cutting tape and an adsorption moving assembly for adsorbing one end of the cut tape are provided at the top of the gantry frame; and a tape and... The magnetron sputtering assembly includes an electroplating tank mounted on the top of the base. Three electroplating rollers are rotatably mounted in an inverted triangle shape within the electroplating tank. Guide rollers are rotatably mounted at both the top and bottom of one side of the electroplating tank. A take-up roller is located on one side of the electroplating tank. A PLC controller is mounted on the base, integrating functions such as tape collection, unwinding, cutting, adsorption bonding, and electroplating / film application into a unified workflow. This eliminates the need for separate operations, significantly improving the electroplating / film application efficiency of the magnetron sputtering film, reducing manual operation, improving processing quality, and adapting to industrial continuous production scenarios.

[0011] Preferably, the lifting assembly includes a vertical frame, which is fixedly installed on the top of the base. A lifting screw is rotatably installed between the upper and lower ends of the vertical frame. A slider is threadedly connected to the outer periphery of the lifting screw. A motor slot is provided at the bottom of the vertical frame, and the bottom of the vertical frame passes through the motor slot and is connected to the lifting motor. The lifting process is smooth and wobbly, and the height of the tape roller can be precisely adjusted to meet the needs of different work processes. There is no need for manual lifting, reducing labor costs, and at the same time, it provides stable support for the subsequent storage of the tape roller.

[0012] Preferably, the storage component includes a cover plate, one side of which is fixedly installed on one side of the slider. The fixing component is located at the bottom of the cover plate, and a storage box fixedly installed on the base is located directly below the cover plate. The unwinding roller is located on the side of the storage box away from the lifting component. When the tape roller is idle, it can descend into the storage box with the lifting component to achieve dustproof, moisture-proof, and impact-proof protection, preventing the tape from getting damp or the roller from being damaged. The cover plate and the slider are linked, and the storage box opens and closes automatically during lifting, without the need for additional manual operation, which is highly convenient.

[0013] Preferably, the fixing assembly includes two brackets, which are fixedly installed on the bottom of the cover plate. An electric push rod and a drive motor are respectively installed at one end of each bracket. Both ends of the tape roller have cross grooves, and cross blocks are inserted into these grooves. The output end of the electric push rod and one cross block are rotatably mounted, while the output end of the drive motor and another cross block are fixedly mounted. The precise fit between the cross grooves and cross blocks ensures both a secure fixation of the tape roller and stable torque transmission, preventing slippage during unwinding. The electric push rod can flexibly adjust the spacing between the cross blocks to adapt to tape rollers of different lengths, offering strong versatility. Disassembly and assembly can be completed simply by extending and retracting the electric push rod, without needing to move the tape roller, saving time and effort.

[0014] Preferably, the slitting mechanism includes a slitting electric cylinder, which is mounted on the top of the gantry frame. A blade holder is mounted on the output end of the slitting electric cylinder, and a slitting blade is provided at the bottom of the blade holder via a replacement component. A blade groove, which is fixedly installed on the gantry frame, is provided directly below the slitting blade. The electric cylinder drives the slitting blade to descend at a uniform speed, resulting in uniform cutting force and a smooth, burr-free cut on the tape. The blade groove and the slitting blade are precisely aligned, avoiding direct impact damage to the blade and extending the blade's life. With the replacement component, worn blades can be quickly replaced, reducing downtime for maintenance.

[0015] Preferably, the replacement component includes a T-slot formed at the bottom of the blade holder along its length. The slitting blade (804) is slidably connected to the T-slot. One side of the blade holder has a first insertion hole communicating with the T-slot, and one side of the slitting blade has a second insertion hole corresponding to the first insertion hole (8032). A rod is slidably installed between the first and second insertion holes. A handle is installed on one side of the rod. The handle and the blade holder are connected by a spring. The T-slot enables lateral positioning of the slitting blade. The rod + spring structure allows for tool-free assembly and disassembly. It can be operated by manually pulling the handle, which is convenient and efficient. The spring automatically resets and fixes the rod, preventing the slitting blade from falling off during operation, ensuring high safety.

[0016] Preferably, the outer wall of the insertion rod is provided with a limiting strip, and the inner walls of the second insertion hole and the first insertion hole are provided with limiting grooves.

[0017] Preferably, the adsorption moving component includes a moving electric cylinder, which is installed on one side of the cutting electric cylinder at the top of the gantry frame. An upper adsorption box is installed at the output end of the moving electric cylinder, and an upper air pump is installed on one side of the upper adsorption box. Several upper negative pressure holes are opened at the bottom of the upper adsorption box. The negative pressure adsorption method does not damage the surface of the tape and is suitable for tapes of different thicknesses.

[0018] Preferably, the roller pressing assembly includes two elongated grooves, which are respectively located below both ends of the gantry frame. A screw is rotatably installed in one of the elongated grooves. One side of the screw is connected to a roller pressing motor, and the outer circumference of the screw is slidably connected to one end of a sliding plate via a thread. A roller pressing electric cylinder is installed at the top center of the sliding plate, and a U-shaped frame is installed at the output end of the roller pressing electric cylinder. A pressing roller is rotatably installed between the two ends of the U-shaped frame. A lower adsorption box parallel to the unwinding roller is fixedly installed between the lower inner walls of both ends of the gantry frame. The top of the lower adsorption box has several negative pressure holes, and the bottom of the lower adsorption box has a lower air pump. The lower adsorption box fixes the magnetic control film with negative pressure to prevent the substrate from shifting during pressing. The screw drives the pressing roller to roll at a uniform speed, resulting in uniform pressing pressure and solving the problem of "detachment" during manual bonding. The electric cylinder adjusts the height of the pressing roller to adapt to magnetic control films and tapes of different thicknesses, making it widely applicable.

[0019] Preferably, a slide rod is fixedly installed in another of the elongated grooves, and the other end of the slide plate is slidably connected to the slide rod. The slide rod and the screw form a "one-drive-one-guide" structure to prevent the slide plate from tilting when it moves and to ensure that the pressing trajectory of the rolling roller is straight.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0021] 1. The height of the conveyor belt roller can be flexibly adjusted via the lifting assembly (vertical frame + lifting screw + slider). Combined with the storage assembly (cover plate + storage box), the conveyor belt roller is automatically stored. When not in use, the lifting assembly lowers the conveyor belt roller into the storage box, and the cover plate and storage box close to form a protective space. When in use, the lifting assembly raises the conveyor belt roller to the working height. No manual handling is required throughout the process, solving the problem of frequent handling required by traditional supports and reducing the labor intensity of operators. The fixing assembly (support + electric push rod + drive motor + cross slot / block) enables quick assembly and disassembly of the conveyor belt roller. When replacing the conveyor belt roller, the electric push rod drives the cross block to disengage from the cross slot at the end of the conveyor belt roller, allowing the old roller to be removed. When installing a new roller, simply align the cross block with the cross slot, and the electric push rod resets to complete the fixing, making operation convenient. Simultaneously, the drive motor ensures stable rotation of the conveyor belt roller, guaranteeing a uniform unwinding speed and avoiding speed fluctuations during manual unwinding.

[0022] 2. The slitting mechanism (electric slitting cylinder + blade holder + slitting blade + blade groove) replaces manual cutting. The electric slitting cylinder drives the blade holder to descend at a uniform speed, and the slitting blade and blade groove precisely match to achieve vertical cutting of the tape, resulting in a clean, burr-free cut. With the replacement assembly (T-slot + insert rod + spring + handle), the slitting blade can be quickly disassembled and assembled (pulling the handle removes the insert rod and the old blade; after inserting the new blade, releasing the handle resets the spring and secures the insert rod), reducing tool maintenance time and ensuring the continuity of the cutting process. The adsorption and movement assembly (electric moving cylinder + upper adsorption box + upper air pump + upper negative pressure hole) enables precise transfer of the tape after cutting. Before cutting, the upper adsorption box descends to the top of the tape under the drive of the electric moving cylinder, and the upper air pump activates to create negative pressure in the upper negative pressure hole to adsorb the tape. After cutting, the electric moving cylinder lowers the upper adsorption box, precisely adhering the tape to the magnetic film surface on the lower adsorption box, avoiding the offset errors of manual alignment and ensuring the accuracy of the bonding position.

[0023] 3. The roller pressing assembly (lower adsorption box + lower air pump + pressing roller + roller electric cylinder + screw) optimizes bonding quality through "fixation" and "pressing". The lower air pump creates negative pressure in the lower negative pressure hole, firmly fixing the magnetron film to the surface of the lower adsorption box and preventing substrate misalignment during pressing. The roller electric cylinder drives the pressing roller to descend to the tape surface, while the screw drives the sliding plate to move at a uniform speed, causing the pressing roller to roll and press along the tape length, ensuring uniform pressure and tight adhesion. This solves the problems of "uneven pressure and easy detachment" in traditional manual bonding, ensuring that the tape and magnetron film move synchronously during subsequent traction and threading, eliminating the risk of detachment. The descent height of the pressing roller (adjusted by the roller electric cylinder) and the moving speed (adjusted by the screw speed) can be precisely controlled, adapting to magnetron films and tapes of different thicknesses and ensuring consistent bonding quality for products of different specifications.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Please see Figure 1-2 This utility model provides a technical solution:

[0035] A composite current collector electroplating film-piercing device includes: a base 1, a lifting component 2 on one side of the top of the base 1, a storage component 3 on the lifting component 2, a tape roller 5 detachably mounted on the storage component 3 via a fixing component 4, a unwinding roller 6 on one side of the storage component 3, the unwinding roller (6) is used to unwind the magnetron sputtering film, a gantry frame 7 fixedly mounted to the base 1 is provided on the side of the unwinding roller 6 away from the lifting component (2), a cutting mechanism 8 for cutting the tape and an adsorption moving component 9 for adsorbing one end of the cut tape are provided on the top of the gantry frame 7, a pressing component 10 for pressing the tape and magnetron sputtering film is provided below the gantry frame 7, an electroplating tank 11 is installed on the other side of the top of the base 1, three electroplating rollers 12 are installed in the electroplating tank 11 in an inverted triangle shape, guide rollers 13 are rotatably installed at both the top and bottom ends of one side of the electroplating tank 11, a winding roller 14 is provided on the other side of the electroplating tank 11, and a PLC controller 15 is provided on the base 1.

[0036] Furthermore, the PLC controller 15 can be a Siemens S7-300 series, the unwinding roller 6 can also be detachably installed on one side of the storage box 302 via a set of fixing components 4, a connecting frame is installed on the top side of the base 1, and the winding roller 14 can also be detachably installed on the connecting frame via a set of fixing components 4.

[0037] Please see Figure 3 In this embodiment: the lifting assembly 2 includes a vertical frame 201, which is fixedly installed on the top of the base 1. A lifting screw 202 is rotatably installed between the upper and lower ends of the vertical frame 201. A slider 203 is threadedly connected to the outer periphery of the lifting screw 202. A motor slot is provided at the bottom of the vertical frame 201. The bottom of the vertical frame 201 passes through the motor slot and is connected to the lifting motor.

[0038] Furthermore, the lifting motor is fixed in the motor slot below the vertical frame 201, and its output shaft is rigidly connected to the bottom of the lifting screw 202 through a coupling, which can drive the lifting screw 202 to rotate in both directions, thereby driving the slider 203 connected by the outer thread to slide up and down along the inner wall of the vertical frame 201; the inner wall of the vertical frame 201 is provided with guide grooves that are adapted to both sides of the slider 203, which can restrict the rotation of the slider 203, ensuring that the slider 203 drives the storage component 3 and the tape roller 5 to rise and fall smoothly without shaking, and avoiding the tape roller 5 from shifting and causing the tape unwinding path to be misaligned.

[0039] Please see Figure 3 In this embodiment: the storage component 3 includes a cover plate 301, one side of the cover plate 301 is fixedly installed with one side of the slider 203, the fixing component 4 is set at the bottom of the cover plate 301, and the storage box 302 fixedly installed with the base 1 is located directly below the cover plate 301. The unwinding roller 6 is set on the side of the storage box 302 away from the lifting component 2.

[0040] Furthermore, the size of the cover plate 301 is perfectly matched with the size of the top opening of the storage box 302. When the tape roller 5 is not in use, the lifting component 2 drives the cover plate 301 to descend to fit against the top of the storage box 302, forming a sealed protective space, which can effectively prevent dust and external collisions, and prevent the tape on the surface of the tape roller 5 from getting damp or wrinkled due to bumps.

[0041] Please see Figure 4 In this embodiment: the fixing component 4 includes two brackets 401, which are fixedly installed at the bottom of the cover plate 301. An electric push rod 402 and a drive motor 403 are respectively installed at one end of the two brackets 401. Both ends of the tape roller 5 are provided with cross grooves 404, and cross blocks 405 are inserted into the cross grooves 404. The output end of the electric push rod 402 and a cross block 405 are rotatably installed, and the output end of the drive motor 403 and another cross block 405 are fixedly installed.

[0042] Furthermore, the cross-sectional dimensions of the cross block 405 are precisely matched with the inner wall dimensions of the cross groove 404. After the two are inserted, they can transmit torque, preventing relative sliding between the tape roller 5 and the cross block 405 when the tape roller 5 rotates, thus ensuring a stable unwinding speed. The electric push rod 402 can adjust the distance between the two cross blocks 405 by telescopic adjustment, adapting to tape rollers 5 of different lengths and improving the versatility of the device. The output end of the electric push rod 402 is rotatably connected to the cross block 405 through a bearing, ensuring that when the drive motor 403 drives the tape roller 5 to rotate, the cross block 405 at the end of the electric push rod 402 can rotate synchronously with the tape roller 5 without jamming.

[0043] Please see Figure 5 In this embodiment: the slitting mechanism 8 includes a slitting electric cylinder 801, which is installed on the top of the gantry 7. A knife holder 802 is installed at the output end of the slitting electric cylinder 801. A slitting knife 804 is provided at the bottom of the knife holder 802 through a replacement component 803. A knife groove 805 fixedly installed with the gantry 7 is provided directly below the slitting knife 804.

[0044] Furthermore, the piston rod of the electric slitting cylinder 801 is fixed to the top of the blade holder 802 by bolts, which can provide a uniform and stable downward driving force and avoid uneven descent speed of the slitting blade 804, which would cause the cut to be skewed. The blade groove 805 is provided with a rubber buffer layer, which can not only prevent the blade of the slitting blade 804 from directly hitting the blade groove 805 and causing damage during cutting, but also prevent the tape from curling up at the moment of cutting by the elasticity of the rubber.

[0045] Please see Figure 7In this embodiment: the replacement component 803 includes a T-slot 8031 ​​opened at the bottom of the tool holder 802 along the length of the tool holder 802, the slitting blade 804 is slidably connected to the T-slot 8031, a first insertion hole 8032 communicating with the T-slot 8031 ​​is opened on one side of the tool holder 802, a second insertion hole 8033 corresponding to the first insertion hole (8032) is opened on one side of the slitting blade 804, an insertion rod 8034 is slidably installed between the first insertion hole 8032 and the second insertion hole 8033, a handle 8035 is installed on one side of the insertion rod 8034, and the handle 8035 and the tool holder 802 are connected by a spring 8036.

[0046] Furthermore, the length of the T-slot 8031 ​​is adapted to the length of the T-shaped structure at the top of the slitting blade 804, which can laterally position the slitting blade 804 and prevent it from moving left and right during slitting. The spring 8036 is sleeved on the outside of the insert rod 8034, with one end fixed to the inside of the handle 8035 and the other end fixed to the outer wall of the blade holder 802. Under normal conditions, the spring 8036 is in a naturally contracted state, pushing the insert rod 8034 to stably insert into the first insertion hole 8032 and the second insertion hole 8033, thus preventing the slitting blade 804 from falling off.

[0047] Please see Figure 7 In this embodiment: the outer wall of the insertion rod 8034 is provided with a limiting strip, and the inner walls of the second insertion hole 8033 and the first insertion hole 8032 are provided with limiting grooves.

[0048] Furthermore, the limiting strip on the outer side of the insertion rod 8034 slides in conjunction with the limiting groove on the inner wall of the first insertion hole 8032 and the second insertion hole 8033, which can prevent the insertion rod 8034 from rotating and ensure that the insertion rod 8034 can be accurately inserted into the second insertion hole 8033.

[0049] Please see Figure 5 In this embodiment: the adsorption moving component 9 includes a moving electric cylinder 901, which is installed on one side of the top part of the gantry 7 cutting electric cylinder 801. The output end of the moving electric cylinder 901 is equipped with an upper adsorption box 902. An upper air pump 903 is installed on one side of the upper adsorption box 902. Several upper negative pressure holes 904 are opened at the bottom of the upper adsorption box 902.

[0050] Furthermore, the upper air pump 903 is a negative pressure pump, and its suction end is connected to the interior of the upper adsorption box 902 through an air pipe. By adjusting the negative pressure value of the upper air pump 903, it can be adapted to tapes of different thicknesses (thin tapes use low negative pressure to avoid damage, and thick tapes use high negative pressure to ensure firm adsorption). The upper negative pressure holes 904 at the bottom of the upper adsorption box 902 are evenly distributed in a matrix, which can balance the adsorption force on the tape and avoid excessive local stress on the tape, resulting in wrinkles.

[0051] Please see Figure 5In this embodiment: the roller pressing assembly 10 includes two long grooves 101, which are respectively opened below the two ends of the gantry frame 7. A screw 102 is rotatably installed in one of the long grooves 101. One side of the screw 102 is connected to the roller pressing motor. The outer periphery of the screw 102 is slidably connected to one end of the slide plate 103 through a thread. A roller pressing electric cylinder 104 is installed at the middle of the top of the slide plate 103. A U-shaped frame 105 is installed at the output end of the roller pressing electric cylinder 104. A pressing roller 106 is rotatably installed between the two ends of the U-shaped frame 105. A lower adsorption box 107 parallel to the unwinding roller 6 is fixedly installed between the lower inner walls of the two ends of the gantry frame 7. Several lower negative pressure holes 108 are opened at the top of the lower adsorption box 107. A lower air pump 109 is provided at the bottom of the lower adsorption box 107.

[0052] Furthermore, both ends of the screw 102 are rotatably connected to the inner wall of the long groove 101 via bearings. The output shaft of the roller press motor is connected to one end of the screw 102 via a coupling, which can drive the screw 102 to rotate in both directions, thereby driving the slide plate 103 to move at a constant speed along the long groove 101. The slide rod in another long groove 101 is slidably engaged with the slide hole opened at the other end of the slide plate 103, forming a "one-drive-one-guide" structure with the screw 102, preventing the slide plate 103 from tilting due to unilateral force when moving, and ensuring uniform pressure when the rolling roller 106 rolls and presses. The outer surface of the rolling roller 106 is covered with a silicone layer with a hardness of 50-60 Shore A, which can not only ensure the friction during pressing, but also adapt to the slight undulations of the magnetron film surface through elastic deformation, thereby improving the adhesion tightness.

[0053] Please see Figure 5 In this embodiment: a slide bar is fixedly installed in another long groove 101, and the other end of the slide plate 103 is slidably connected to the slide bar.

[0054] Furthermore, the slide bar is made of 45 steel with a chrome-plated surface, which reduces the coefficient of friction with the sliding hole 103 of the slide plate, reduces wear, and extends service life.

[0055] The workflow of this embodiment is as follows: The tape on the tape roller 5 first passes between the slitting knife 804 and the knife groove 805, then passes under the upper adsorption box 902, then passes the bottom of the lower guide roller 13, then passes the bottom of the upper guide roller 13, then enters the electroplating tank 11 and passes through three electroplating rollers 12, and is finally wound up by the take-up roller 14. The magnetron film is unwound by the unwinding roller 6. After one end of the magnetron film moves to the top of the lower adsorption box 107, the lower air pump 109 is activated to generate negative pressure in the lower negative pressure hole 108 to adsorb the magnetron film. Then, the moving electric cylinder 901 drives the upper adsorption box 902 to descend and contact the top of the tape. Then, the upper air pump 903 is activated to generate negative pressure in the upper negative pressure hole 904 to adsorb the tape. The slitting electric cylinder 801 drives the knife holder 802 to descend and slit the tape. When the blade 804 descends and contacts the blade groove 805, it cuts the tape. Then, the moving electric cylinder 901 continues to drive the upper adsorption box 902 to descend until the tape contacts and bonds with the magnetron film on the lower adsorption box 107. Then, the upper air pump 903 is turned off, and the moving electric cylinder 901 drives the upper adsorption box 902 to rise back to its original position. The roller pressing electric cylinder 104 is activated, causing the pressing roller 106 to descend and contact the tape on the lower adsorption box 107. The screw 102 is rotated to move the slide plate 103, causing the pressing roller 106 to roll on the tape for pressing, making the tape and magnetron film bond more firmly. After bonding, the pressing roller 106 rises back to its original position, and the winding roller 14 rotates to wind up the tape. The tape drives the magnetron film to move, thus completing the molding of the magnetron film. Automatic tape cutting and bonding make the process more convenient and labor-saving. When the tape roller 5 is not in use, rotating the lifting screw 202 causes the slider 203 to descend, which in turn causes the cover plate 301 to descend and contact the top of the storage box 302, allowing the tape roller 5 to fall into the storage box 302 for storage. When in use, it can be raised again, eliminating the need for manual handling and making it more convenient. The cover plate 301 and the storage box 302 also provide protection for the tape roller 5. After the tape roller 5 is used up, hold the tape roller 5 and start the electric push rod 402 to make the cross block 405 at the output end of the electric push rod 402 disengage from the cross groove 404, and then the tape roller 5 can be removed. When replacing the tape roller 5, first connect the cross groove 404 at one end of the tape roller 5 to the cross block 405 at the output end of the drive motor 403. The electric push rod 402 then drives the cross block 405 to insert into another cross groove 404, thus completing the fixing of the tape roller 5. The drive motor 403 drives the cross block 405 to rotate, which can make the tape roller 5 rotate. When the slitting blade 804 is worn and needs to be removed for maintenance, the handle 8035 can be held and pulled to make the insertion rod 8034 leave the insertion hole 8033 and stretch the spring 8036, which can pull the slitting blade 804 to leave the T-slot 8031 ​​to complete the disassembly. During installation, the handle 8035 is pulled in the same way, and then the slitting blade 804 is inserted into the T-slot 8031. Then the handle 8035 is released, and the restoring force of the spring 8036 makes the insertion rod 8034 insert into the insertion hole 8033, thus completing the fixing of the slitting blade 804.
