Description

Technical Field

[0001] This invention relates to the field of packaging equipment technology, specifically to a packaging device for the production of cable accessories. Background Technology

[0002] In the production of cable accessories, the packaging process is crucial, as its quality directly affects the safety and integrity of the cable accessories during transportation and storage. This is especially true for wrapping with adhesive film; the tightness, flatness, and neatness of the cut edges of the wrapping material all have a decisive impact on the overall packaging quality. Currently, some packaging devices for cable accessory production exist on the market. These existing devices have achieved the function of wrapping cable accessories with adhesive film to a certain extent. However, in practical applications, existing technologies still have many shortcomings, seriously restricting the improvement of packaging quality.

[0003] In terms of film lamination, the design of the pressure roller in the existing device is not reasonable enough. During the process of pressing the film traction end onto the surface of the cable roll workpiece and the subsequent winding process, the pressure roller cannot maintain a stable and appropriate pressure. This makes the film prone to loosening, wrinkling or air bubbles during the winding process, which greatly reduces the tightness of the packaging and fails to effectively protect the cable accessories. It also greatly reduces the aesthetics of the packaging and makes it difficult to meet the market's demand for high-quality packaging.

[0004] Existing devices also have shortcomings in terms of film traction and clamping. On the one hand, they lack an effective initial stabilization mechanism. In the initial stage of traction and clamping, the film is prone to positional displacement due to external factors or its own tension, affecting the accuracy of subsequent operations. On the other hand, the traction and clamping components do not work well together. During traction, the film is prone to loosening or falling off, making it impossible to guarantee the stability of the film during traction. Moreover, the linkage between the components in existing devices is not flexible or stable enough during clamping and traction, making it difficult to achieve precise traction and reliable clamping of the film, further affecting packaging quality. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a packaging device for cable accessory production, which solves the technical problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solution: a packaging device for cable fitting production, comprising a base and a cable roll workpiece, an mounting plate fixedly installed on the top of the base, a steel ring provided on the front surface of the mounting plate, and an adhesive film for wrapping the cable roll workpiece on one side of the steel ring.

[0007] A positioning shaft is fixedly connected to the surface of the steel ring, and a film is sleeved on the positioning shaft. The surface of the positioning shaft has a groove. A fixing rod is fixedly installed at one end of the positioning shaft, and a connecting rod is provided at the other end of the positioning shaft. A horizontal plate is fixedly connected to the bottom end of the fixing rod. Slide rods are fixedly connected to both ends of the horizontal plate. A fixed plate and a movable plate are provided on the slide rod. The fixed plate is fixedly installed on the slide rod, and the movable plate is slidably installed on the slide rod. A cutting tool for cutting the film is provided at the opposite ends of the fixed plate and the movable plate. A first damping spring is sleeved on the slide rod on both sides of the fixed plate and the movable plate. A second cylinder is fixedly installed on the horizontal plate, and the output end of the second cylinder is fixedly connected to the movable plate.

[0008] As a further preferred embodiment of this technical solution, a connecting frame is fixedly connected to the outer end of the fixed plate, a rotating plate is rotatably connected to the inner side of the connecting frame, a pressure roller is provided at the end of the rotating plate, and a second damping spring is provided at the inner end of the connecting frame to push the rotating plate to rotate toward the side of the cable roll workpiece.

[0009] As a further preferred embodiment of this technical solution, vertical rods are fixedly connected to both sides of the fixed plate, and slide blocks are slidably connected to the outer walls of the vertical rods in the vertical direction. A movable rod is slidably connected to the slide blocks, and a pressure plate is fixedly connected to one end of the movable rod near the movable plate. A third damping spring is sleeved on the movable rod between the slide blocks and the pressure plate.

[0010] As a further preferred embodiment of this technical solution, a plug-in rod is fixedly connected to the end of the moving rod away from the movable plate, and a guide roller is rotatably provided on the inner end of the plug-in rod, with the guide roller sliding in contact with the surface of the vertical rod.

[0011] As a further preferred embodiment of this technical solution, a drive motor is fixedly connected to the top of the fixed plate, a lead screw is fixedly connected to the output end of the drive motor, a movable block is threaded onto the lead screw, the movable block is slidably mounted on the fixed plate in the vertical direction, and one end of the plug rod is slidably mounted on the movable block.

[0012] As a further preferred embodiment of this technical solution, the vertical rod is provided with a clamping end on the side away from the pressure plate, and a first release end and a second release end located on both sides of the clamping end. The guide roller slides on the first release end, the clamping end, and the second release end. A groove is provided on the surface of the vertical rod near the pressure plate. A positioning rod is fixedly connected to the inner wall of the groove. A docking block is slidably connected to the positioning rod. Protrusions corresponding to the positions of the docking blocks are provided on both sides of the pressure plate, and a fourth damping spring is provided at the bottom of the docking block and sleeved on the positioning rod.

[0013] As a further preferred embodiment of this technical solution, positioning wheels are rotatably connected to both sides of the mounting plate surface. A tensioning wheel mounted on the mounting plate is provided between the two positioning wheels. A friction synchronous belt is provided for transmission between the tensioning wheel and the two positioning wheels. The outer surface of the friction synchronous belt is frictionally transmitted with the outer wall of the steel ring. A first servo motor is fixedly mounted on the back of the mounting plate. The output end of the first servo motor is fixedly connected to one of the positioning wheels. Three sets of limit wheels are rotatably mounted on the mounting plate on both sides of the steel ring.

[0014] As a further preferred embodiment of this technical solution, rotating rollers are rotatably connected to both sides of the base surface, and a second servo motor is fixedly installed at the bottom of the base. The output end of the second servo motor is connected to one of the rotating rollers through a first synchronous belt pulley transmission component, and the two rotating rollers are connected through a second synchronous belt pulley transmission component.

[0015] As a further preferred embodiment of this technical solution, mounting rods are fixedly installed on the upper and lower ends of the back of the mounting plate, and movable plates are slidably connected to the two mounting rods. The two movable plates are connected by a third synchronous belt pulley transmission component. A first cylinder is fixedly installed on one side of the back of the mounting plate, and the output end of the first cylinder is fixedly connected to one of the movable plates. Clamping rollers are rotatably installed on the upper and lower ends of the movable plate near the steel ring.

[0016] Compared with existing technologies, it has the following advantages:

[0017] This device, through its ingenious structural design, automates a series of operations, including film installation, traction, clamping, bonding, and cutting. Throughout the packaging process, manual intervention is significantly reduced, with each step seamlessly integrated and executed in an orderly manner. For example, in the film installation stage, the detachable connecting rod design allows operators to quickly install the film roll without complex procedures or lengthy manual work, saving considerable time. In the traction and clamping stages, the drive motor coordinates the relevant components to precisely and quickly pull the film to the designated position and clamp it, greatly improving efficiency compared to traditional manual traction and clamping methods. In the cutting stage, the second cylinder drives the movable plate to move, working in conjunction with the cutter to achieve rapid cutting. The entire packaging process is completed in one go, significantly shortening the packaging time for a single cable roll and thus improving overall packaging efficiency.

[0018] When the movable plate is moved towards the fixed plate by the second cylinder for cutting, the first damping spring buffers the moving speed of the movable plate, allowing the cutter to cut the film with uniform and stable force. This avoids problems such as uneven cutting, film tearing, or cutter damage caused by excessive cutting speed, ensuring neat and smooth cutting edges and laying the foundation for high-quality packaging. In terms of film bonding, the design of the pressure roller assembly is ingenious. The second damping spring pushes the rotating plate to rotate, which in turn causes the pressure roller to tightly press the traction end of the film onto the surface of the cable roll workpiece. Pressure is maintained throughout the winding process, allowing the film to be tightly and smoothly wound onto the cable roll workpiece. This effectively prevents the film from loosening, wrinkling, or forming bubbles, improving the tightness and aesthetics of the packaging.

[0019] The film traction and clamping assembly achieves stable and reliable traction and clamping of the film through the coordinated work of multiple components. The third damping spring applies a certain pressure to the film in the initial stage, keeping it in a relatively stable position for easy subsequent operation. The sliding of the guide roller on the special track (clamping end, second release end) and its linkage with the moving block, plug rod, and other components achieve precise traction and clamping of the film. During the clamping process, the special shape design of the clamping end forces the pressure plate and the docking block to tightly clamp the film traction end, ensuring that the film will not loosen or fall off during traction. At the same time, the fourth damping spring enables the docking block to move synchronously with the pressure plate and reset at the appropriate time, ensuring the stability and reliability of the entire traction and clamping process, thereby improving packaging quality.

[0030] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Example 1: Combining Figures 1-9 As shown, the present invention provides a technical solution: a packaging device for cable accessories production. The packaging device mainly consists of a base 1 and a cable roll workpiece 5 forming a basic frame. The base 1 serves as the supporting component of the entire device, and an installation plate 2 is fixedly installed on its top, providing a stable installation platform for other components. A steel ring 3 is provided on the front surface of the installation plate 2. The steel ring 3 is one of the core components for the installation and wrapping of the adhesive film 4. An adhesive film 4 for wrapping and packaging the cable roll workpiece 5 is provided on one side of the steel ring 3.

[0032] A positioning shaft 31 is fixedly connected to the surface of the steel ring 3. The positioning shaft 31 plays a role in positioning and supporting the entire device. One end of the positioning shaft 31 is fixedly installed with a fixing rod 32, providing a fixed mounting point for other components; the other end is provided with a connecting rod 33. The connecting rod 33 is assembled onto the positioning shaft 31 in a detachable and fixed manner with the aid of a locking structure. This detachable design has many advantages. When installing the adhesive film 4, the operator can easily remove the connecting rod 33, roll the adhesive film 4 onto the positioning shaft 31, and then reinstall and fix the connecting rod 33, thus completing the installation of the adhesive film 4 conveniently and quickly. A horizontal plate 34 is fixedly connected to the bottom end of the fixing rod 32. The horizontal plate 34 serves as a bridge connecting and supporting other components. Slide rods 35 are fixedly connected to both ends of the horizontal plate 34. A fixed plate 36 and a movable plate 37 are provided on the slide rods 35. The fixed plate 36 is fixedly installed on the slide rods 35, providing a stable reference for the entire cutting and traction system. The movable plate 37 is slidably installed on the slide rods 35, enabling linear reciprocating motion on the slide rods 35. A cutting tool 38 for cutting the adhesive film 4 is provided at the opposite ends of the fixed plate 36 and the movable plate 37. The traction end of the adhesive film 4 passes between the fixed plate 36 and the movable plate 37. This design allows the movable plate 37 to move toward the fixed plate 36 when the adhesive film 4 needs to be cut, so that the cutting tool 38 can precisely cut the adhesive film 4.

[0033] To enable the automatic movement of the movable plate 37, a second cylinder 39 is fixedly installed on the horizontal plate 34. The output end of the second cylinder 39 is fixedly connected to the movable plate 37. After the adhesive film 4 finishes wrapping the cable roll workpiece 5, the output end of the second cylinder 39 will push the movable plate 37 to move towards the fixed plate 36 by opening the second cylinder 39. At the same time, in order to prevent the movable plate 37 from moving too fast, which would cause the cutter 38 to cut the adhesive film 4 unevenly or damage the cutter 38, a first damping spring 310 sleeved on the slide rod 35 is provided on both sides of the fixed plate 36 and the movable plate 37. When the movable plate 37 moves, the first damping spring 310 will provide pressure buffer for the moving movable plate 37, so that the movable plate 37 can move smoothly, thereby ensuring that the cutter 38 performs uniform and neat cutting of the adhesive film 4.

[0034] A connecting frame 311 is fixedly connected to the outer end of the fixed plate 36. A rotating plate 312 is rotatably connected to the inner side of the connecting frame 311. A pressure roller 313 is provided at the end of the rotating plate 312. A second damping spring 314 is provided at the inner end of the connecting frame 311 to push the rotating plate 312 to rotate toward the cable roll workpiece 5. When the traction end of the adhesive film 4 moves to the position between the cable roll workpiece 5 and the pressure roller 313, the elastic force of the second damping spring 314 can push the rotating plate 312 to rotate around the connecting frame 311, thereby pushing the pressure roller 313 to move toward the cable roll workpiece 5. This allows the pressure roller 313 to press the traction end of the cable roll workpiece 5 onto the surface of the cable roll workpiece 5. This design ensures that the traction end of the adhesive film 4 can be tightly attached to the cable roll workpiece 5, laying the foundation for the subsequent smooth winding of the adhesive film 4 onto the cable roll workpiece 5.

[0035] Vertical rods 315 are fixedly connected to both sides of the fixed plate 36. A slide block 316 is slidably connected to the outer wall of the vertical rod 315 in the vertical direction. A moving rod 317 is slidably connected to the slide block 316. A pressure plate 318 is fixedly connected to one end of the moving rod 317 near the movable plate 37. A third damping spring 319 is sleeved on the moving rod 317 between the slide block 316 and the pressure plate 318. The traction end of the diaphragm 4 passes through the vertical rod 315 and the pressure plate 318. Under the elastic force of the third damping spring 319, the pressure plate 318 will be pushed to move away from the vertical rod 315. However, due to the obstruction of the vertical rod 315, the pressure plate 318 will exert a certain pressure on the diaphragm 4, so that the diaphragm 4 can maintain a relatively stable position in the initial stage, which is convenient for subsequent clamping and traction operations.

[0036] A connecting rod 320 is fixedly connected to the end of the movable rod 317 away from the movable plate 37. A guide roller 321 is rotatably mounted on the inner end of the connecting rod 320. The guide roller 321 slides against the surface of the vertical rod 315. A drive motor 324 is fixedly connected to the top of the fixed plate 36. A lead screw 322 is fixedly connected to the output end of the drive motor 324. A moving block 323 is threaded onto the lead screw 322. The moving block 323 slides vertically on the fixed plate 36, and one end of the connecting rod 320 slides on the fixed plate 36. When the drive motor 324 is turned on, it will drive the lead screw 322 to rotate synchronously. Since the moving block 323 is threadedly connected to the lead screw 322 and can only slide vertically on the fixed plate 36, the rotation of the lead screw 322 will cause the moving block 323 to move vertically. The movement of the moving block 323 will drive the insertion rod 320, guide roller 321, moving rod 317, slide 316, and pressure plate 318 to move together, thereby realizing the traction and clamping operation of the adhesive film 4.

[0037] A clamping end 328 and a first release end 326 and a second release end 327 located on both sides of the clamping end 328 are provided on the side of the vertical rod 315 away from the pressure plate 318. The guide roller 321 slides on the first release end 326, the clamping end 328 and the second release end 327. A sliding groove 325 is provided on the surface of the vertical rod 315 near the pressure plate 318. A positioning rod 329 is fixedly connected to the inner wall of the sliding groove 325. A docking block 330 is slidably connected to the positioning rod 329. Protrusions corresponding to the positions of the docking blocks 330 are provided on both sides of the pressure plate 318. A fourth damping spring 331 is provided at the bottom of the docking block 330 and is sleeved on the positioning rod 329. Under the elastic force of the fourth damping spring 331, the docking block 330 can be pushed to move upward and reset.

[0038] The guide roller 321 is initially positioned at the first release end 326. After the traction end of the adhesive film 4 passes between the vertical rod 315 and the pressure plate 318, the drive motor 324 is activated to drive the lead screw 322 to rotate synchronously. This causes the lead screw 322 to move the moving block 323, the insertion rod 320, the guide roller 321, the moving rod 317, the slide block 316, and the pressure plate 318 downwards. The guide roller 321 moves from the first release end 326 to the clamping end 328. During the process of moving to the clamping end 328, due to the characteristics of the clamping end 328... The special shape design forces the guide roller 321, the insertion rod 320, the moving rod 317, and the pressure plate 318 to move towards the fixed plate 36 and compress the third damping spring 319, so that the pressure plate 318 moves to the position of the docking block 330. At this time, the docking block 330 and the pressure plate 318 clamp the traction end of the adhesive film 4. As the moving block 323 continues to move downward, the docking block 330 can move downward synchronously with the pressure plate 318, so that the docking block 330 and the pressure plate 318 drive the traction end of the adhesive film 4 to move downward synchronously.

[0039] After the traction end of the adhesive film 4 moves to a position below the pressure roller 313, the elastic force of the second damping spring 314 allows the pressure roller 313 to push the traction end of the adhesive film 4 into contact with the surface of the cable roll workpiece 5. As the guide roller 321 continues to move downward to the position of the second release end 327, the shape design of the second release end 327 will prevent the guide roller 321 from being subjected to the squeezing force towards the fixed plate 36. Under the elastic restoring force of the third damping spring 319, the pressure plate 318 will move away. The pressure plate 318 moves away from the fixed plate 36, thereby separating it from the docking block 330 and ceasing to hold the adhesive film 4. At this time, the docking block 330 moves back to its original position under the elastic force of the fourth damping spring 331. Simultaneously, the drive motor 324 is turned on to drive the lead screw 322 to rotate in the opposite direction, thereby driving the moving block 323, the insertion rod 320, the guide roller 321, the moving rod 317, the slide 316, and the pressure plate 318 to move upward and reset, preparing for the next adhesive film traction and clamping operation.

[0040] In an embodiment of the present invention, after the traction end of the adhesive film 4 smoothly passes through the gap between the vertical rod 315 and the pressure plate 318, the drive motor 324 is immediately started. The drive motor 324 drives the lead screw 322 to rotate synchronously through the transmission device. The rotation of the lead screw 322 then drives the moving block 323, the insertion rod 320, the guide roller 321, the moving rod 317, the slide 316, and the pressure plate 318 to move downward as a whole. During this process, the guide roller 321 gradually moves from the initial first release end 326 position to the clamping end 328 position. During the process of the guide roller 321 moving to the clamping end 328, the guide roller 321, the insertion rod 320, the moving rod 317, and the pressure plate 318 will move together towards one side of the fixed plate 36, and in this process, the third damping spring 319 is compressed. As the pressure plate 318 moves to the predetermined position of the docking block 330, the docking block 330 and the pressure plate 318 jointly pull the adhesive film 4. The lead end is firmly clamped. As the moving block 323 continues to move downward, the docking block 330 can move downward synchronously with the pressure plate 318, thereby driving the traction end of the adhesive film 4 to move downward synchronously. When the traction end of the adhesive film 4 moves to the position below the pressure roller 313, under the elastic force of the second damping spring 314, the pressure roller 313 will push the traction end of the adhesive film 4 to make close contact with the surface of the cable roll workpiece 5. When the guide roller 321 moves to the position of the second release end 327, the pressure plate 318 separates from the docking block 330. At this time, the pressure plate 318 and the docking block 330 no longer clamp the adhesive film 4. The docking block 330 automatically resets under the elastic force of the fourth damping spring 331. At the same time, the drive motor 324 drives the lead screw 322 to rotate in the opposite direction, thereby driving the moving block 323, the insertion rod 320, the guide roller 321, the moving rod 317, the slide 316 and the pressure plate 318 to move upward and reset as a whole.

[0041] After the adhesive film 4 completes the wrapping and packaging of the cable roll workpiece 5, the second cylinder 39 is activated, which drives the movable plate 37 to move to one side of the fixed plate 36. During this process, the first damping spring 310 effectively buffers the pressure of the moving movable plate 37 to ensure smooth movement. Finally, the cutter 38 at the opposite end of the fixed plate 36 and the movable plate 37 performs precise and neat cutting of the adhesive film 4, completing the entire packaging process.

[0042] Example 2: Combination Figure 8 , Figure 9As shown, based on Embodiment 1, positioning wheels 23 are mounted on both sides of the surface of the mounting plate 2 via a rotatable connection. Between these two positioning wheels 23, a tensioning wheel 22 is also provided on the mounting plate 2. Specifically, the distance between these two positioning wheels 23 is designed to be greater than the width of the slot 332. This design aims to ensure that the friction synchronous belt 24 always maintains a tight fit with the outer wall of the steel ring 3. In this way, when the friction synchronous belt 24 is in motion, it can effectively drive the steel ring 3 to rotate synchronously. The tensioning wheel 22 is connected to the two positioning wheels 23 via the friction synchronous belt 24. The outer surface of the friction synchronous belt 24 forms a friction transmission configuration with the outer wall of the steel ring 3. A first servo motor 21 is fixedly mounted on the back of the mounting plate 2. The output end of the first servo motor 21 is connected to one of the... The positioning wheel 23 is fixedly connected, and three sets of limiting wheels 25 are provided on both sides of the steel ring 3. These limiting wheels 25 are mounted on the mounting plate 2 by rotation. The six limiting wheels 25 are used to clamp and limit the steel ring 3. By turning on the first servo motor 21, the positioning wheel 23 is driven to rotate. The positioning wheel 23, together with the tension wheel 22 and another positioning wheel 23, drives the friction synchronous belt 24 to be connected for transmission. The friction synchronous belt 24 drives the steel ring 3 to rotate synchronously through friction. Then, the steel ring 3 drives the positioning shaft 31, the fixed rod 32, the connecting rod 33, the sliding rod 35, the fixed plate 36, the movable plate 37, the cutter 38, the rotating plate 312, the vertical rod 315, the pressure plate 318 and the adhesive film 4 to rotate synchronously. Finally, the adhesive film 4 wraps and packages the cable roll workpiece 5.

[0043] Rotating rollers 27 are mounted on both sides of the surface of the base 1 via a rotatable connection. A second servo motor 26 is fixedly mounted at the bottom of the base 1. The output end of the second servo motor 26 is connected to one of the rotating rollers 27 via a first synchronous belt pulley transmission component 28, and the two rotating rollers 27 are connected to each other via a second synchronous belt pulley transmission component 29. The cable roll workpiece 5 is placed between the two rotating rollers 27. By turning on the second servo motor 26, the second servo motor 26 drives the rotating roller 27 to rotate synchronously via the first synchronous belt pulley transmission component 28. The rotating roller 27 then drives the other rotating roller 27 to rotate synchronously via the second synchronous belt pulley transmission component 29. Thus, the cable roll workpiece 5 is rotated by the two rotating rollers 27, so that the adhesive film 4 can wrap and package the cable roll workpiece 5.

[0044] Mounting rods 210 are fixedly mounted on the upper and lower ends of the back of mounting plate 2. Movable plates 211 are slidably connected to these two mounting rods 210, and these two movable plates 211 are connected via a third synchronous belt pulley transmission component 213. A first cylinder 212 is fixedly mounted on one side of the back of mounting plate 2. The output end of the first cylinder 212 is fixedly connected to one of the movable plates 211. Clamping rollers 214 are rotatably mounted on the upper and lower ends of the movable plate 211 near the steel ring 3. The holding roller 214 facilitates the rotation of the cable roll workpiece 5 and the subsequent winding and packaging of the cable roll workpiece 5. When it is necessary to clamp and limit the cable roll workpiece 5, the first cylinder 212 is activated to drive the moving plate 211 to move inward. The moving plate 211 drives another moving plate 211 to move inward synchronously through the third synchronous belt pulley transmission component 213, so that the two moving plates 211 move inward at the same time, and finally the moving plate 211 drives the clamping roller 214 to clamp and limit the cable roll workpiece 5.

[0045] In an embodiment of the present invention, the cable reel workpiece 5 is precisely placed at the center of the two rotating rollers 27. By activating the first cylinder 212, the moving plate 211 is driven to move smoothly inward. The moving plate 211 is precisely driven by the third synchronous belt pulley transmission component 213, which drives the moving plate 211 on the other side to move inward synchronously as well, ensuring that the two moving plates 211 can move inward simultaneously and in a coordinated manner. This process enables the moving plate 211 to effectively drive the clamping roller 214 to perform a stable and precise clamping and limiting treatment on the cable reel workpiece 5, ensuring that the cable reel workpiece 5 remains stable in subsequent operations.

[0046] Next, by turning on the second servo motor 26, the second servo motor 26 drives one of the rotating rollers 27 to rotate synchronously through the first synchronous belt pulley transmission component 28. The rotating roller 27 then drives the other rotating roller 27 to rotate synchronously through the second synchronous belt pulley transmission component 29. Thus, through the synergistic action of the two rotating rollers 27, the cable roll workpiece 5 is driven to rotate smoothly. This process ensures that the adhesive film 4 can wrap and package the cable roll workpiece 5 evenly and tightly, thus guaranteeing the packaging quality.

[0047] Furthermore, by activating the first servo motor 21, the positioning wheel 23 is driven to rotate precisely. The positioning wheel 23, the tensioning wheel 22, and another positioning wheel 23 work closely together to drive the friction synchronous belt 24 for transmission connection. The friction synchronous belt 24 drives the steel ring 3 to rotate synchronously through the friction force it generates. The rotation of the steel ring 3 further drives the positioning shaft 31, the fixed rod 32, the connecting rod 33, the sliding rod 35, the fixed plate 36, the movable plate 37, the cutter 38, the rotating plate 312, the vertical rod 315, the pressure plate 318, and the adhesive film 4 to rotate synchronously. This series of linkage mechanisms ensures that the adhesive film 4 can efficiently and accurately wrap and package the cable roll workpiece 5, ultimately achieving a high-quality packaging effect.
