Description

Technical Field

[0001] This invention belongs to the field of cable transportation protection technology, specifically, it relates to a temporary packaging device for cable transportation. Background Technology

[0002] During the production, transportation, and storage of cables, temporary packaging is usually required to prevent scratches on the cable surface caused by collisions and friction, or to prevent the performance from being affected by external moisture and dust. Currently, cable packaging mostly relies on wrapping with protective film. The film forms physical protection for the cable, reducing damage to the cable from the external environment and ensuring the integrity and safety of the cable during transportation and subsequent use.

[0003] Currently, in temporary cable packaging operations, existing packaging methods still rely on manual packaging in most scenarios. Manual operation not only makes it difficult to achieve uniform wrapping of the protective film around the cable, but also easily causes problems such as film wrinkles, excessive or insufficient thickness in some areas, resulting in inconsistent packaging quality, failing to provide stable and reliable protection for the cable, and having low efficiency, making it difficult to meet the packaging needs of batch cables.

[0004] While packaging equipment is already used in some scenarios, improving packaging efficiency to some extent, existing equipment generally lacks intelligent detection of film remaining. When the protective film runs out during operation, the equipment cannot provide early warning or automatically trigger a response, often leading to sudden interruptions in the packaging process. This requires manual shutdown and replacement of the film roll before work can continue, increasing downtime and rework time and severely impacting overall production progress. Furthermore, when the film runs out, the film already wrapped around the cable end is prone to loosening due to loss of tension, requiring additional re-sorting, further increasing operational steps and reducing packaging efficiency. In addition, after stopping to replace the film roll and restarting the equipment to continue packaging, the initial position of the film must be manually adjusted to ensure connection with the loose film at the cable end. This operation is cumbersome and prone to connection deviations, affecting packaging integrity. Therefore, this invention is proposed. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a temporary packaging device for cable transportation that can overcome or at least partially solve the above problems.

[0006] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by the present invention is as follows:

[0007] A temporary packaging device for cable transportation includes a base on which a base plate is fixedly mounted. It further includes: a drive mechanism for rotating the cable to be packaged, disposed on the base; a clamping mechanism for assisting cable rotation, disposed on the base plate; a rotating ring with a cable loading / unloading port, rotatably connected to the base plate; a first bearing shaft and a second bearing shaft, both fixedly connected to the rotating ring and each equipped with a removable protective film, the former being in an active state and the latter in a standby state; a detection triggering mechanism, a glue spraying mechanism, and a pressing and splicing mechanism, all connected to the rotating ring and respectively located at... On the right, left, and directly above the bearing shaft one, when the rotating ring drives the protective film in the working state to wrap the cable, the detection trigger mechanism will detect the remaining thickness of the protective film in the working state. When the conductive ring two in the detection trigger mechanism contacts the conductive ring one, it will trigger the glue spraying mechanism and the pressing splicing mechanism to work: the nozzle of the glue spraying mechanism sprays glue onto the surface of the protective film in the working state; the electrostatic adsorption roller of the pressing splicing mechanism presses the initial end of the protective film in the standby state onto the surface of the protective film in the working state, and completes the splicing of the two through glue.

[0011] Furthermore, the pressing and splicing mechanism includes a fixed plate, a U-shaped plate, and an electromagnet. The electromagnet is fixedly mounted on the fixed plate and magnetically connected to the U-shaped plate. The switch of the electromagnet is jointly controlled by conductive ring two and conductive ring one. The electrostatic adsorption roller is rotatably connected to the U-shaped plate. A guide rod one is fixedly connected to the U-shaped plate and slidably connected to the fixed plate. The fixed plate is fixedly connected to the rotating ring. A spring two is sleeved on the guide rod one and is located between the fixed plate and the U-shaped plate.

[0012] For driving the rotating ring to rotate, preferably, the base plate is equidistantly connected with multiple guide wheels around the axis of the rotating ring, and the guide wheels are in contact with the outer wall of the rotating ring. Two drive shafts are symmetrically rotatably connected to the base plate, and pulleys are fixedly installed at both ends of the two drive shafts. The two pulleys located on the rear side of the base plate are connected by belt 2, and the two pulleys on the front side are connected by belt 1. Belt 1 is in contact with the outer wall of the rotating ring. A tension wheel is rotatably connected to the base plate and abuts against belt 1. A motor 1 is fixedly installed on the base plate, and the drive shaft is fixedly connected to the output end of motor 1.

[0013] To further adjust the tension of belt one, a sliding groove is provided on the base plate, an adjusting block is slidably connected in the sliding groove, a connecting shaft is rotatably connected to the adjusting block, the tensioning wheel is fixedly installed on the connecting shaft, a tensioning spring is provided between the groove wall of the sliding groove and the lower end face of the adjusting block, an adjusting groove is provided on the adjusting block, and a fixing bolt threadedly connected to the base plate is inserted in the adjusting groove.

[0014] For driving the cable to be packaged to rotate, preferably, the driving mechanism includes a rotating shaft symmetrically rotatably connected to the base, with pulleys and friction rollers fixedly installed on both rotating shafts. The two pulleys are connected by a three-phase belt.

[0018] In this invention, the driving mechanism and the clamping mechanism work together to ensure that the cable rotates stably during the packaging process, effectively preventing cable deviation, ensuring uniform winding of the protective film, and improving the stability and consistency of packaging quality.

[0019] The rotating ring drives the protective film to move around the cable, achieving 360° full wrapping of the cable. Compared with manual wrapping or partial wrapping, this shortens the packaging time and improves packaging efficiency.

[0020] The detection triggering mechanism can accurately monitor the working status and the remaining thickness of the protective film. When the thickness reaches the set threshold, it will trigger the splicing action in time to avoid packaging interruption due to the use of film, ensure the continuous packaging work, and reduce downtime and rework time.

The glue spraying mechanism sprays glue evenly, while the pressing and splicing mechanism achieves rapid and firm splicing of the film through electrostatic adsorption and pressing, and the splicing joint is flat, which does not affect the appearance and protective effect of the cable packaging. The entire splicing process does not require manual intervention, reducing the intensity of manual labor and further improving the overall packaging efficiency. Attached Figure Description

[0038] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0039] Example 1: Refer to Figure 1 , Figure 2 , Figure 3 , Figure 7 , Figure 9 , Figure 10 , Figure 11 , Figure 13 A temporary packaging device for cable transportation includes a base 1, on which a base plate 101 is fixedly mounted. It also includes: a drive mechanism for rotating the cable to be packaged, mounted on the base 1; a clamping mechanism for assisting cable rotation, mounted on the base plate 101; a rotating ring 103 with a cable loading / unloading port, rotatably connected to the base plate 101; a first bearing shaft 6 and a second bearing shaft 604, both fixedly connected to the rotating ring 103 and each equipped with a removable protective film, the former being in a working state and the latter in a standby state; a detection triggering mechanism, a glue spraying mechanism, and a pressing and splicing mechanism, all connected to the rotating ring 103 and respectively positioned... On the right, left, and directly above the bearing shaft 6, when the rotating ring 103 drives the protective film in the working state to wrap the cable, the detection triggering mechanism will detect the remaining thickness of the protective film in the working state. When the conductive ring 713 in the detection triggering mechanism contacts the conductive ring 712, it will trigger the glue spraying mechanism and the pressing splicing mechanism to work: the nozzle 806 of the glue spraying mechanism sprays glue onto the surface of the protective film in the working state; the electrostatic adsorption roller 709 of the pressing splicing mechanism presses the initial end of the protective film in the standby state onto the surface of the protective film in the working state, and completes the splicing of the two through glue.

[0040] During operation, the cable to be packaged is first placed on the drive mechanism and clamping mechanism through the cable loading and unloading port on the rotating ring 103. Then, the operator wraps the initial end of the protective film on the bearing shaft 6 around the cable. Then, the drive mechanism is started, and the drive mechanism drives the cable to be packaged to rotate around its own axis. At the same time, the rotating ring 103 starts to rotate, which drives the protective film on the bearing shaft 6 in the working state to move around the cable and wrap the cable.

[0041] During the packaging process, the detection triggering mechanism continuously detects the remaining thickness of the protective film in the working state on the bearing shaft 6. As the protective film is used, its thickness gradually decreases, and the detection component in the detection triggering mechanism moves accordingly. When the remaining thickness of the protective film reaches the set threshold, the conductive ring 713 in the detection triggering mechanism contacts the conductive ring 712 to form a circuit path. At this time, the circuit signal triggers the glue spraying mechanism and the pressing and splicing mechanism to work simultaneously: the nozzle 806 of the glue spraying mechanism sprays glue evenly onto the surface of the protective film in the working state; the electrostatic adsorption roller 709 of the pressing and splicing mechanism first adsorbs the initial end of the protective film in the standby state on the bearing shaft 604 through electrostatic adsorption, and then presses it onto the surface of the protective film in the working state coated with glue. The two are spliced ​​by the adhesive effect of the glue. After the splicing is completed, the protective film on the bearing shaft 604 turns to the working state and continues to package the cable. The used protective film roll on the bearing shaft 6 can be disassembled and replaced later to achieve a continuous supply of protective film.

[0042] Throughout the process, the coordination of the drive mechanism and the clamping mechanism ensures stable rotation of the cable during packaging, preventing cable deviation from affecting packaging quality and improving packaging stability and consistency. The rotation of the rotating ring 103 drives the protective film to move around the cable, achieving comprehensive wrapping and packaging, thus improving packaging efficiency. The detection triggering mechanism can accurately detect the remaining thickness of the protective film and trigger the splicing action in a timely manner, avoiding interruption of the packaging process due to the depletion of the protective film and ensuring the continuity of packaging work. The coordinated work of the glue spraying mechanism and the pressing splicing mechanism enables rapid and firm splicing of the protective film, with a smooth splice that does not affect the appearance and protective effect of the packaged cable. At the same time, no manual intervention is required in the splicing process, reducing labor intensity and improving overall packaging efficiency.

[0043] After the cable packaging operation is completed, first turn off the drive mechanism, and at the same time, the rotating ring 103 stops rotating. It must be ensured that when the rotating ring 103 stops, the cable loading and unloading port on it is in a vertically downward position. Then, the protective film wrapped around the cable is cut manually or by using a special cutting component. Subsequently, the clamping mechanism is controlled to release the clamping constraint on the cable. Finally, the operator can remove the packaged cable from the vertically downward cable loading and unloading port, completing a single cable packaging operation.

[0044] Example 2: Refer to Figure 1 , Figure 2 , Figure 3 , Figure 7 , Figure 9 , Figure 10 , Figure 11 , Figure 12 , Figure 13A temporary packaging device for cable transportation is basically the same as in Embodiment 1, but further, the detection triggering mechanism includes a detection cylinder 7, a slider 701, a mounting frame 704, and a detection roller 703. The detection roller 703 is rotatably connected to the mounting frame 704. The detection cylinder 7 is fixedly connected to the rotating ring 103. The slider 701 is slidably connected inside the detection cylinder 7. The mounting frame 704 is fixedly connected to the slider 701 through a connecting rod 702. A spring 705 is provided inside the detection cylinder 7. One end of the spring 705 is fixedly connected to the inner wall of the detection cylinder 7, and the other end is fixedly connected to the slider 701. The detection roller 703 forms a contact fit with the surface of the protective film that is in working state. A conductive ring 713 is fixedly connected to the slider 701, and a conductive ring 712 is fixedly installed on the inner wall of the detection cylinder 7.

[0045] The glue spraying mechanism includes a piston disc 901, a liquid storage tank 902, and an infusion tube 807. The detection cylinder 7 is provided with a spraying chamber 9. The piston disc 901 is slidably connected in the spraying chamber 9. The liquid storage tank 902 is fixedly connected to the detection cylinder 7. The spraying chamber 9 is connected to the liquid storage tank 902 through the infusion tube 903. A hollow rod 802 is connected to the rotating ring 103. Multiple nozzles 806 are equidistantly arranged on the hollow rod 802. One end of the infusion tube 807 is fixedly connected to the spraying chamber 9, and the other end is fixedly connected to the hollow rod 802. A solenoid valve is provided on the infusion tube 807. The opening and closing of the solenoid valve is jointly controlled by the conductive ring 713 and the conductive ring 712. The piston disc 901 is fixedly connected to the connecting rod 702.

[0046] The pressing and splicing mechanism includes a fixed plate 706, a U-shaped plate 708, and an electromagnet 710. The electromagnet 710 is fixedly installed on the fixed plate 706 and magnetically connected to the U-shaped plate 708. The switch of the electromagnet 710 is jointly controlled by conductive ring 2 713 and conductive ring 1 712. The electrostatic adsorption roller 709 is rotatably connected to the U-shaped plate 708. A guide rod 1 707 is fixedly connected to the U-shaped plate 708 and slidably connected to the fixed plate 706. The fixed plate 706 is fixedly connected to the rotating ring 103. A spring 2 711 is sleeved on the guide rod 1 707 and is located between the fixed plate 706 and the U-shaped plate 708.

[0047] It also includes a connecting plate 8 fixedly connected to the rotating ring 103, a second guide rod 804 slidably connected to the connecting plate 8, a U-shaped frame 801 fixedly connected to one end of the second guide rod 804, a hollow rod 802 fixedly connected to the U-shaped frame 801, a roller 803 rotatably connected to the hollow rod 802, the roller 803 forming a contact fit with the surface of the protective film in the working state, and a third spring 805 sleeved on the second guide rod 804, the third spring 805 being located between the connecting plate 8 and the U-shaped frame 801.

[0048] Before packaging the cable, first install the working state protection film roll on the bearing shaft 6 and the standby state protection film roll on the bearing shaft 604. Ensure that the two film rolls are firmly installed and can be smoothly laid. Then, add enough glue to the storage tank 902 to reserve the bonding medium for the subsequent glue spraying process. This step can complete the material replenishment at one time, reduce the downtime of frequent material addition during the packaging process, and improve the equipment start-up efficiency.

[0049] Then, the operator manually adjusts the position of the detection roller 703, and pushes the mounting bracket 704 to move the connecting rod 702 into the detection cylinder 7, which in turn pushes the slider 701 to compress the spring 705, so that the spring 705 stores elastic potential energy until the detection roller 703 is tightly attached to the working state protective film surface. During this adjustment process, the connecting rod 702 simultaneously pushes the piston disc 901, which is fixedly connected to it, to slide in the spraying chamber 9. The internal volume of the spraying chamber 9 increases to form a negative pressure. The glue in the storage tank 902 is drawn into the spraying chamber 9 through the infusion pipe 903, realizing the automatic pre-filling of glue. There is no need for additional manual glue extraction, which simplifies the debugging steps, reduces manual operation, and reduces the debugging difficulty. At the same time, it ensures that the spraying chamber 9 is pre-stored with glue to avoid glue interruption problems during subsequent glue spraying.

[0050] At this time, the slider 701 has not slid to the trigger position, the conductive ring 712 and the conductive ring 713 are not in contact, and the solenoid valve of the glue spraying mechanism is in the closed state to prevent the glue from leaking prematurely. Meanwhile, the electromagnet 710 of the pressing splicing mechanism is pre-energized. After being energized, the electromagnet 710 generates a strong magnetic attraction force, which magnetically attracts the U-shaped plate 708 to move upward, causing the U-shaped plate 708 to compress the spring 711, allowing the spring 711 to store elastic potential energy. At the same time, it drives the electrostatic adsorption roller 709 away from the working state protective film roll to avoid premature contact and damage to the film. During this process, the initial end of the standby state protective film roll adheres to the surface of the electrostatic adsorption roller 709 through electrostatic adsorption, realizing the precise pre-positioning of the initial end of the standby film.

[0051] When the cable packaging work starts, the drive mechanism drives the cable to rotate around its own axis. The rotating ring 103 simultaneously drives the detection trigger mechanism, the glue spraying mechanism and the pressing splicing mechanism to rotate around the cable. In the working state, the protective film is released from the bearing shaft 6 and wrapped around the surface of the cable. During this stage, the detection trigger mechanism continues to work.

[0052] Previously compressed, spring 705 gradually reduces its reaction force on slider 701 as the protective film is continuously wrapped and consumed. Spring 705 begins to gradually release its elastic potential energy. During the release of elastic potential energy, spring 705 generates a continuous and stable thrust on slider 701, which drives slider 701 to drive the detection roller 703 on mounting frame 704 to always press tightly against the surface of the protective film in the working state through connecting rod 702, ensuring that the detection roller 703 and the film have no gap contact. In this process, the spring elastic force achieves self-adaptive bonding between detection roller 703 and film, eliminating the need for real-time manual adjustment and reducing labor intensity.

[0053] As the protective film is continuously consumed, its roll diameter gradually decreases. Under the thrust of spring 705, the detection roller 703 moves towards the center of the protective film roll, and then drives the slider 701 to slide axially in the detection cylinder 7 via the connecting rod 702. During this process, the displacement of the detection roller 703 is linearly related to the reduction in the film roll diameter, which can reflect the change in the remaining film thickness in real time. Moreover, by adopting this mechanical contact detection, the detection action is directly driven by the change in the physical morphology of the film, and is not affected by external environmental factors such as temperature and humidity, resulting in good detection stability.

[0054] When the remaining thickness of the protective film decreases to the set threshold, the slider 701 slides precisely to the position where the conductive ring 713 contacts the conductive ring 712. At this time, the circuit is connected and a trigger signal is generated. This contact triggering method has a rapid response, with no delay from the film thickness meeting the standard to the signal generation. It can provide a timely start signal for the glue spraying mechanism and the pressing and splicing mechanism, avoiding packaging interruption due to the film running out, ensuring the continuity of the packaging process, and reducing cable exposure or packaging rework problems caused by film breakage. At the same time, the conductive ring triggering structure is simple, has low manufacturing cost, and only requires checking the conductive contact status for later maintenance, making maintenance convenient.

[0055] As the slider 701 slides as the film thickness decreases, the connecting rod 702 simultaneously pushes the piston disc 901 to move towards the side of the infusion tube 807 within the spraying chamber 9. The adhesive in the spraying chamber 9 is squeezed and gradually pressed into the infusion tube 807. Since the infusion tube 807 is an expandable and contractible hose, it can adaptively expand and contract with the movement of the piston disc 901, without interfering with the sliding of the slider 701 and the piston disc 901. This ensures that the detection and pre-compression actions are carried out synchronously, without the need for additional power to drive the compression. By utilizing the sliding action of the detection mechanism to synchronously complete the pre-compression of the adhesive, the spraying power structure is simplified, and the equipment energy consumption and failure probability are reduced.

[0056] When conductive ring 2 713 contacts conductive ring 1 712 and the circuit is connected, the solenoid valve of the glue spraying mechanism opens. The glue that was previously squeezed into the infusion tube 1 807 is quickly fed into the hollow rod 802 under pressure. Then, it is atomized and sprayed onto the surface of the working film through multiple equally spaced nozzles 806, so that the glue forms a uniform and fine glue mist. The coverage area is adapted to the width of the film, avoiding local accumulation or omission of glue, ensuring the uniformity of glue spraying, providing a stable bonding foundation for subsequent film splicing, and reducing glue waste.

[0057] During this process, the spring 805 between the U-shaped frame 801 and the connecting plate 8 is always in a compressed state. Its elasticity pushes the U-shaped frame 801 to drive the hollow rod 802 and the roller 803 to fit tightly against the film surface. When the film roll diameter changes, the roller 803 moves synchronously with the film surface, driving the hollow rod 802 and the nozzle 806 to adaptively adjust their positions, so that the distance between the nozzle 806 and the film surface is always kept at the optimal spraying distance. This avoids the glue being sprayed too thickly, too thinly, or unevenly due to spacing fluctuations, ensuring a consistent glue layer thickness and improving the sealing and firmness of the splice. At the same time, the roller 803 adopts a rolling contact method to avoid sliding friction with the film surface, which could cause scratches on the film, protect the integrity of the film, and ensure packaging quality.

[0058] When conductive ring 2 713 contacts conductive ring 1 712, electromagnet 710 receives a trigger signal and is de-energized, its magnetic attraction disappears. At this time, the previously compressed spring 2 711 releases its elastic potential energy, generating a downward thrust, which pushes U-shaped plate 708 downward along guide rod 1 707. Guide rod 1 707 provides stable guidance for U-shaped plate 708, preventing U-shaped plate 708 from shifting during movement and causing misalignment during splicing.

[0059] As the U-shaped plate 708 moves downward, it drives the electrostatic adsorption roller 709 to move downward synchronously, precisely pressing the initial end of the standby protective film adsorbed on its surface onto the working film surface that has been sprayed with adhesive. Because the adhesive layer on the working film surface is uniform, the two are tightly bonded under the pressing force of the electrostatic adsorption roller 709, and the adhesive quickly forms bonding force, completing the seamless splicing of the two films. The rolling pressing method of the electrostatic adsorption roller 709 can make the force at the splicing point uniform, avoiding weak bonding caused by insufficient local pressure, realizing automatic and precise splicing of films, with high splicing efficiency, and good sealing at the splicing point to prevent moisture and impurities from entering during transportation.

[0060] The spliced ​​composite film continues to move with the rotating ring 103. When it passes the detection roller 703, the detection roller 703 performs a secondary flattening process on the splice under the thrust of the spring 705, eliminating any small gaps that may be generated during splicing, further enhancing the bonding strength of the splice, ensuring that the splice will not crack or fall off during the subsequent packaging process, and improving the splicing quality.

[0061] After the current cable packaging is completed, equipment reset and material replenishment are required: the remaining protective film roll (already in working condition) on carrier shaft 2 604 is moved to carrier shaft 1 6 for continued use. Then, a new protective film roll is installed on carrier shaft 2 604, and the above preparation stage debugging steps are repeated to prepare for the next cable packaging. This finishing method can make full use of the remaining film and avoid material waste. At the same time, the standardized reset process can quickly complete the equipment switchover, improve material utilization, reduce packaging costs, and the equipment switchover efficiency is high, which can meet the needs of batch cable packaging.

[0062] It should be noted that both infusion tubing 807 and infusion tubing 903 are equipped with one-way valves.

[0063] Example 3: Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 14 , Figure 15 A temporary packaging device for cable transportation is basically the same as in Embodiment 1. However, the additional device has a base plate 101 with multiple guide wheels 102 equidistantly connected around the axis of the rotating ring 103. The guide wheels 102 are in contact with the outer wall of the rotating ring 103. Two drive shafts 2 are symmetrically rotatably connected to the base plate 101. Pulleys are fixedly installed at both ends of the two drive shafts 2. The two pulleys on the rear side of the base plate 101 are connected by belt 202, and the two pulleys on the front side are connected by belt 201. Belt 201 is in contact with the outer wall of the rotating ring 103. A tension wheel 203 is rotatably connected to the base plate 101 and abuts against belt 201. A motor 204 is fixedly installed on the base plate 101, and the drive shafts 2 are fixedly connected to the output end of the motor 204.

[0064] When motor 204 is started, its output torque is transmitted to drive shaft 2 connected to it via a coupling. The pulleys at both ends of drive shaft 2 rotate synchronously. Since the rear pulley is connected via belt 202 and the front pulley is connected via belt 201, the two drive shafts 2 will rotate synchronously in the same direction under the action of belt transmission. At this time, belt 201, which is in contact with the outer wall of rotating ring 103, moves under the drive of drive shaft 2. Through the friction between belt 201 and rotating ring 103, rotating ring 103 is driven to rotate around its own axis. During the rotation of rotating ring 103, the guide wheels 102, which are equidistantly arranged around it, will roll with the movement of rotating ring 103, providing radial support and guidance for rotating ring 103, preventing radial offset or swaying of rotating ring 103 during rotation, ensuring the stability of rotating ring 103, and thus ensuring that the protective film on the bearing shaft can be evenly wrapped around the cable surface, improving packaging accuracy.

[0065] When belt 201 loosens after a period of use, the friction between it and rotating ring 103 decreases, potentially causing slippage. At this time, the tensioning pulley 203, acting as a stop against the inner side of belt 201, automatically or manually adjusts the tension of belt 201, ensuring that belt 201 remains tightly fitted to rotating ring 103, preventing slippage, ensuring stable power transmission, reducing packaging interruptions caused by power transmission interruptions, and improving the continuous working capacity of the equipment. Simultaneously, the selection of a servo motor as motor 204 allows for precise adjustment of the motor speed through the control system, thereby controlling the rotation speed of rotating ring 103, achieving precise control of the protective film winding speed, adapting to cables of different diameters and packaging requirements, and improving the versatility and flexibility of the equipment.

[0066] The drive mechanism includes a rotating shaft 4 symmetrically rotatably connected to the base 1. Both rotating shafts 4 are fixedly mounted with pulleys and friction rollers 401. The two pulleys are connected by a third belt 402. A second motor 404 is fixedly mounted on the lower end face of the base 1. Both the output end of the second motor 404 and the rotating shaft 4 are fixedly mounted with pulleys. The two pulleys are connected by a fourth belt 403.

[0067] The cable to be packaged is placed in the clamping space between the two friction rollers 401. The second motor 404 is started. The output torque of the second motor 404 is transmitted to the rotating shaft 4 connected to it through the fourth belt 403. The rotating shaft 4 rotates accordingly. Since the two rotating shafts 4 are connected by the third belt 402, the other rotating shaft 4 rotates synchronously under the drive of the third belt 402. At this time, the two friction rollers 401 rotate synchronously with the rotating shaft 4. Through the friction between the outer surface of the friction rollers 401 and the outer wall of the cable, the cable is driven to rotate around its own axis.

[0068] During cable rotation, the protective film winding action driven by the rotating ring 103 achieves spiral wrapping of the protective film on the cable surface. The friction roller 401 is made of high-friction rubber material, which increases the friction with the cable surface, ensuring stable cable rotation and avoiding slippage. This ensures the stability of the cable rotation speed, resulting in uniform wrapping of the protective film and reducing problems such as film overlap or excessive gaps caused by unstable cable speed. This improves the tightness and aesthetics of the cable packaging. Meanwhile, the second motor 404 is a geared motor, which can provide greater torque and drive cables of different diameters to rotate, adapting to the packaging needs of different cable specifications and improving the versatility of the equipment. In addition, the two symmetrically arranged friction rollers 401 play a certain clamping and positioning role for the cable, preventing axial displacement of the cable during rotation and further ensuring packaging accuracy.

[0069] The clamping mechanism includes a slide bar 502 symmetrically fixedly connected to the base plate 101 and a mounting plate 5 symmetrically slidably connected to the slide bar 502. The upper and lower ends of the mounting plate 5 are rotatably connected to clamping rollers 501. Rollers 503 are symmetrically rotatably connected to the base plate 101. Each of the two rollers 503 is provided with a pulley. The two pulleys are connected to each other by a belt 504. Both mounting plates 5 are connected to the belt 504 by clamping plates. An electric telescopic rod 505 is fixedly installed on the base plate 101. The telescopic end of the electric telescopic rod 505 is fixedly connected to the mounting plate 5.

[0070] According to the diameter of the cable to be packaged, the electric telescopic rod 505 is controlled to extend and retract. The telescopic end of the electric telescopic rod 505 pushes the mounting plate 5 connected to it to slide along the slide rod 502. Since the mounting plate 5 is fixedly connected to one side of the belt 504 through the clamp, the sliding of the mounting plate 5 will drive the belt 504 to move along the roller 503. The other mounting plate 5 is fixedly connected to the other side of the belt 504. Under the drive of the belt 504, the two mounting plates 5 will move synchronously towards or in opposite directions, thereby adjusting the distance between the two mounting plates 5, so that the upper and lower symmetrical clamping rollers 501 can make close contact with the outer wall of the cable, thereby achieving the clamping of the cable.

[0071] During cable packaging, when the drive mechanism rotates the cable, friction is generated between the cable and the clamping roller 501, causing the clamping roller 501 to rotate around its own axis. The rotation of the clamping roller 501 not only does not hinder the rotation of the cable, but also plays an auxiliary guiding and positioning role for the cable, preventing radial runout or axial displacement of the cable during rotation, ensuring that the cable is always in the center position, and ensuring that the protective film can be evenly wrapped around the cable surface, improving the accuracy and stability of packaging. At the same time, through the cooperation of the electric telescopic rod 505 and the belt 504, the two mounting plates 5 can be adjusted synchronously, ensuring the consistency of adjustment. The adjustment process is highly automated, requiring no manual adjustment, reducing the difficulty of operation, improving the adaptability of the equipment, and quickly adapting to the clamping requirements of cables of different diameters, reducing equipment adjustment time, and improving packaging efficiency. In addition, the clamping roller 501 is made of rubber, which can avoid scratching or squeezing damage to the cable surface while clamping the cable, protecting the appearance quality of the cable.

[0072] A sliding groove is provided on the substrate 101, and an adjusting block 3 is slidably connected in the sliding groove. A connecting shaft 301 is rotatably connected to the adjusting block 3. A tensioning wheel 203 is fixedly installed on the connecting shaft 301. A tensioning spring 303 is provided between the groove wall of the sliding groove and the lower end face of the adjusting block 3. An adjusting groove 302 is provided on the adjusting block 3, and a fixing bolt 304 threadedly connected to the substrate 101 is inserted into the adjusting groove 302.

[0073] When the equipment is working normally, the tension spring 303 is in a compressed state. Its upward elastic force pushes the adjusting block 3 to slide upward along the slide groove, causing the connecting shaft 301 and the tension wheel 203 to move upward synchronously. This ensures that the tension wheel 203 is always tightly pressed against the inner side of the belt 201, providing continuous tension to the belt 201. When the belt 201 becomes stretched and loose due to long-term use, the pressure of the belt 201 on the tension wheel 203 decreases. The elastic force of the tension spring 303 will push the adjusting block 3 to slide further upward, and the tension wheel 203 will move upward accordingly, increasing the degree of compression on the belt 201. This automatically compensates for the looseness of the belt 201, maintains the tension of the belt 201, avoids transmission slippage caused by belt looseness, ensures the stability of the rotation speed of the rotating ring 103, and thus ensures the consistency of cable packaging quality.

[0074] When it is necessary to replace belt 201 or adjust the initial position of tension wheel 203, first loosen the fixing bolt 304. At this time, the adjusting block 3 can slide freely in the slide groove. Press the adjusting block 3 down to compress the tension spring 303, which will drive the tension wheel 203 to move downward, increasing the distance between the tension wheel 203 and belt 201, making it easier to disassemble or install belt 201. After adjustment, move the adjusting block 3 to the appropriate position and tighten the fixing bolt 304. Through the cooperation of the fixing bolt 304 and the adjusting groove 302, the adjusting block 3 is fixed in the slide groove, realizing the locking of the position of tension wheel 203. This structure can not only automatically compensate for belt slack, but also has a manual adjustment function. It is easy to operate, reduces the difficulty of equipment maintenance, reduces maintenance time, and improves the maintenance efficiency of the equipment.

[0075] Example 4: Reference Figure 8 , Figure 9 , Figure 10 A temporary packaging device for cable transportation is basically the same as that in Embodiment 1. Furthermore, two conical blocks 601 are sleeved on both the first bearing shaft 6 and the second bearing shaft 604. The two conical blocks 601 are located on both sides of the protective film. A locking ring 602 with a groove is sleeved on the end of the first bearing shaft 6 and the second bearing shaft 604 away from the rotating ring 103. A locking bolt 603 is threaded on the locking ring 602.

[0076] When installing the protective film roll, first, fit the two conical blocks 601 onto the first bearing shaft 6 or the second bearing shaft 604. Then, fit the protective film roll onto the bearing shaft, positioning the protective film roll between the two conical blocks 601. The conical surfaces of the conical blocks 601 center and position the protective film roll, preventing radial displacement of the protective film roll on the bearing shaft. This ensures the coaxiality of the protective film roll during rotation, thereby ensuring that the protective film is evenly released and avoiding uneven film winding caused by film roll displacement, thus improving packaging quality.

[0077] After installing the protective film roll and the conical block 601, the locking ring 602 is fitted onto the end of the bearing shaft, and then the locking bolt 603 is tightened. The tightening force of the locking bolt 603 causes the groove of the locking ring 602 to shrink, and the inner wall of the locking ring 602 fits tightly against the outer wall of the bearing shaft, thus securing the locking ring 602 to the bearing shaft. The locking ring 602 can axially limit the conical block 601 and the protective film roll, preventing them from falling off the end of the bearing shaft during rotation, thus ensuring the safety and stability of the equipment operation.

[0078] When the protective film roll is used up and needs to be replaced, simply loosen the locking bolt 603, and the groove of the locking ring 602 will return to its original state. Then, the locking ring 602 can be unscrewed from the bearing shaft. After that, remove the used film roll and the conical block 601, and then install the new protective film roll according to the above steps. The replacement process is simple and convenient, without the need for complicated tools, which reduces the film replacement time and improves the continuous working efficiency of the equipment.

[0079] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention.
