Description

Technical Field

[0001] The invention belongs to the technical field of cable transportation protection, and in particular relates to a temporary packaging device for cable transportation. Background Art

[0002] During cable production, transportation, and storage, temporary packaging is usually required to prevent scratches on the cable surface caused by collision and friction, or to prevent the cable performance from being affected by erosion by external moisture and dust. Currently, cable packaging mostly relies on wrapping with protective film, which provides physical protection for the cable, reduces damage to the cable from the external environment, and ensures 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 work in most scenarios. Manual operation not only makes it difficult to evenly wrap the protective film around the cable, but also easily leads to problems such as film wrinkles, excessive thickness or thinness in certain areas, resulting in uneven packaging quality, unable to provide stable and reliable protection for the cables, and low efficiency, making it difficult to adapt to the packaging needs of bulk cables. Although packaging equipment has been used in some scenarios and packaging efficiency has been improved to a certain extent, existing equipment generally lacks the function of intelligent detection of film residue: when the protective film in the working state is exhausted, the equipment cannot issue an early warning or automatically trigger a response action, which often leads to a sudden interruption of the packaging process. It is necessary to manually stop the machine and replace a new film roll before continuing the operation. This not only increases the downtime and rework time, but also seriously affects the overall production progress. When the film is exhausted, the film wrapped around the tail end of the cable is prone to loosening due to loss of tension, and additional secondary sorting processing is required, which further increases the operation steps and reduces packaging efficiency. In addition, after stopping the machine to replace the film roll, when restarting the equipment to continue packaging, it is necessary to manually adjust the position of the initial end of the film to ensure that it is connected with the loose film at the tail end of the cable. The operation is cumbersome and prone to connection deviations, which affects the integrity of the packaging. In view of this, the present invention is specially proposed. Summary of the Invention

DETAILED DESCRIPTION

[0018] In order to make the purpose, 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 in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0019] Example 1: Reference 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, and further includes: a driving mechanism for driving the cable to be packaged to rotate, which is arranged on the base 1; a clamping mechanism for assisting the rotation of the cable, which is arranged on the base plate 101; a rotating ring 103 with a cable loading and unloading port, which is rotatably connected to the base plate 101; a bearing shaft 1 6 and a bearing shaft 2 604, which are both fixedly connected to the rotating ring 103 and are both equipped with a detachable protective film, the former is in working state and the latter is in standby state; a detection trigger mechanism, a glue spraying mechanism, and a press splicing mechanism, which are all connected to the rotating ring 103 and are respectively located at On the right side, left side and directly above the load-bearing shaft 6, when the rotating ring 103 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 2 713 in the detection trigger mechanism contacts the conductive ring 1 712, the glue spraying mechanism and the press-and-splice mechanism will be triggered to work: the nozzle 806 of the glue spraying mechanism sprays glue to the surface of the protective film in the working state; the electrostatic adsorption roller 709 of the press-and-splice mechanism presses the initial end of the protective film in the standby state to the surface of the protective film in the working state, and completes the splicing of the two through glue.

[0020] During operation, the cable to be packaged is first placed on the driving mechanism and the clamping mechanism through the cable loading and unloading port on the rotating ring 103. Then, the operator wraps the initial end of the working protective film on the bearing shaft 106 around the cable, and then starts the driving mechanism. The driving mechanism drives the cable to be packaged to rotate along its own axis. At the same time, the rotating ring 103 starts to rotate, driving the protective film on the bearing shaft 106 in the working state to move around the cable, and the cable is wrapped and packaged. During the packaging process, the detection trigger mechanism continuously detects the remaining thickness of the working state protective film on the bearing shaft 1 6. As the protective film is continuously used, its thickness gradually decreases, and the detection component in the detection trigger mechanism moves accordingly. When the remaining thickness of the protective film reaches the set threshold, the conductive ring 2 713 in the detection trigger mechanism contacts the conductive ring 1 712 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 evenly sprays glue to the surface of the working state protective film; the electrostatic adsorption roller 709 of the pressing and splicing mechanism first adsorbs the initial end of the standby state protective film on the bearing shaft 2 604 through electrostatic adsorption, and then presses it to the surface of the working state protective film coated with glue, and completes the splicing of the two through the viscosity of the glue. After the splicing is completed, the protective film on the bearing shaft 2 604 is transferred to the working state to continue packaging the cable, and the used protective film roll on the bearing shaft 1 6 can be disassembled and replaced later to achieve a continuous supply of protective film. During the entire process, the cooperation of the driving mechanism and the clamping mechanism ensures that the cable can rotate stably during packaging, avoids cable deviation affecting the packaging quality, and improves the stability and consistency of the packaging; the rotation of the rotating ring 103 drives the protective film to move around the cable, realizing comprehensive cable wrapping packaging and improving packaging efficiency; the detection trigger mechanism can accurately detect the remaining thickness of the protective film and trigger the splicing action in time to avoid interruption of the packaging process due to exhaustion of the protective film, thereby ensuring the continuity of the packaging work; the coordinated work of the glue spraying mechanism and the pressing splicing mechanism can realize fast and firm splicing of the protective film, and the splicing is smooth, which does not affect the appearance and protective effect of the cable after packaging. At the same time, there is no need for manual intervention in the splicing process, which reduces manual labor intensity and improves overall packaging efficiency. When the cable packaging operation is completed, the driving mechanism is first closed, and the rotating ring 103 stops rotating at the same time. It is necessary to ensure that when the rotating ring 103 stops, the cable loading and unloading port opened on it is just in a vertical downward position. Then, the protective film wrapped around the cable is cut manually or by a special cutting component. Then, the clamping mechanism is controlled to loosen the clamping constraint on the cable. Finally, the operator can remove the packaged cable from the vertically downward cable loading and unloading port to complete a single cable packaging operation.

[0021] Example 2: Reference Figure 1 、 Figure 2 、 Figure 3 、 Figure 7 、 Figure 9 、 Figure 10 、 Figure 11 、 Figure 12 、 Figure 13 A temporary packaging device for cable transportation is basically the same as that of Example 1.

A liquid spraying chamber 9 is provided in the detection cylinder 7. The piston disc 901 is slidably connected to the liquid spraying chamber 9. The liquid storage tank 902 is fixedly connected to the detection cylinder 7. The liquid spraying chamber 9 is connected to the liquid storage tank 902 through the second infusion tube 903. The rotating ring 103 is connected to the hollow rod 802. Multiple nozzles 806 are equidistantly arranged on the hollow rod 802. One end of the infusion tube 807 is fixedly connected to the liquid spraying chamber 9, and the other end is fixedly connected to the hollow rod 802. An electromagnetic valve is provided on the infusion tube 807. The switch of the electromagnetic valve is jointly controlled by the second conductive ring 713 and the first conductive ring 712. The piston disc 901 is fixedly connected to the connecting rod 702. The pressing and splicing mechanism includes a fixed plate 706, a U-shaped plate 708, and an electromagnet 710. The electromagnet 710 is fixedly mounted on the fixed plate 706 and is magnetically connected to the U-shaped plate 708. The switch of the electromagnet 710 is controlled by a second conductive ring 713 and a first conductive ring 712. The electrostatic adsorption roller 709 is rotatably connected to the U-shaped plate 708. The U-shaped plate 708 is fixedly connected to a guide rod 1 707. The guide rod 1 707 is slidably connected to the fixed plate 706. The fixed plate 706 is fixedly connected to the rotating ring 103. A second spring 711 is sleeved on the guide rod 1 707. The second spring 711 is located between the fixed plate 706 and the U-shaped plate 708. It also includes a connecting plate 8 fixedly connected to the rotating ring 103, a guide rod 2 804 is slidably connected to the connecting plate 8, one end of the guide rod 2 804 is fixedly connected to the U-shaped frame 801, a hollow rod 802 is fixedly connected to the U-shaped frame 801, a roller 803 is rotatably connected to the hollow rod 802, the roller 803 forms a contact fit with the surface of the protective film in a working state, a spring 3 805 is sleeved on the guide rod 2 804, and the spring 3 805 is located between the connecting plate 8 and the U-shaped frame 801.

[0022] Before packaging the cables, first install the working state protective film roll on the bearing shaft 1 6, and the standby state protective film roll on the bearing shaft 2 604, ensuring that the two film rolls are firmly installed and can be smoothly unwound. Then, add sufficient glue to the liquid storage tank 902 to reserve the bonding medium for the subsequent glue spraying process. This step can complete the material replenishment in one step, reduce the downtime caused by frequent material additions during the packaging process, and improve the efficiency of equipment startup preparation. Then, the operator manually adjusts the position of the detection roller 703, and drives the connecting rod 702 to move toward the inside of the detection cylinder 7 by pushing the mounting bracket 704, thereby pushing the slider 701 to compress the spring 1 705, so that the spring 1 705 stores elastic potential energy until the detection roller 703 is tightly fitted to the surface of the protective film in the working state. During this adjustment process, the connecting rod 702 synchronously drives the piston disk 901 fixedly connected thereto to slide in the spray chamber 9, and the internal volume of the spray chamber 9 increases to form a negative pressure, and the glue in the liquid storage tank 902 is drawn into the spray chamber 9 through the infusion tube 2 903, thereby realizing automatic pre-filling of glue, without the need for additional manual operation to draw glue, simplifying the debugging steps, reducing the manual operation links, and reducing the difficulty of debugging. At the same time, it ensures that the spray chamber 9 is pre-stocked with glue to avoid the problem of glue breaking during subsequent glue spraying. At this time, the slider 701 has not slid to the trigger position, the conductive ring 1 712 is not in contact with the conductive ring 2 713, and the solenoid valve of the glue spraying mechanism is in a closed state to prevent the glue from leaking prematurely; and the electromagnet 710 of the pressing and splicing mechanism is pre-energized. After being energized, the electromagnet 710 generates a strong magnetic attraction, which magnetically attracts the U-shaped plate 708 to move upward, causing the U-shaped plate 708 to compress the spring 2 711, allowing the spring 2 711 to store elastic potential energy, and at the same time drives the electrostatic adsorption roller 709 away from the working state protection film roll to avoid damage to the film caused by premature contact. In this process, the initial end of the standby state protection film roll is attached to the surface of the electrostatic adsorption roller 709 through electrostatic adsorption, thereby realizing accurate pre-positioning of the initial end of the standby film.

[0023] When the cable packaging work is started, the driving mechanism drives the cable to rotate around its own axis, and the rotating ring 103 synchronously drives the detection trigger mechanism, the glue spraying mechanism and the pressing and 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 cable surface. During this stage, the detection trigger mechanism continues to work; The spring 1 705, which was previously in a compressed state, gradually reduces its reaction force on the slider 701 as the protective film is continuously wound and consumed, and the spring 1 705 begins to gradually release its elastic potential energy. During the release of the elastic potential energy, the spring 1 705 generates a continuous and stable thrust on the slider 701, pushing the slider 701 to drive the detection roller 703 on the mounting frame 704 through the connecting rod 702 to always press tightly against the surface of the protective film in the working state, ensuring that the detection roller 703 and the film are in seamless contact. In this process, the detection roller 703 and the film are adaptively fitted by the spring elastic force, eliminating the need for manual real-time adjustment and reducing labor intensity. As the protective film is continuously consumed, its roll diameter gradually decreases. Under the thrust of spring 1 705, the detection roller 703 moves toward the center of the protective film roll, and then drives the slider 701 to slide axially in the detection cylinder 7 through the connecting rod 702. During this process, the displacement of the detection roller 703 is linearly proportional to the reduction in the roll diameter of the film, which can reflect the change in the remaining thickness of the film in real time. Moreover, by adopting this mechanical contact detection method, the detection action is directly driven by the change in the physical form of the film, and is not affected by external environmental factors such as temperature and humidity, and the detection stability is good. When the remaining thickness of the protective film decreases to a set threshold, the slider 701 slides to the position where the conductive ring 2 713 contacts the conductive ring 1 712. At this time, the circuit is connected and a trigger signal is generated. This contact triggering method responds quickly, and there is no delay from the film thickness reaching the standard to the signal generation. It can provide a start signal to the glue spraying mechanism and the pressing and splicing mechanism in time, avoiding packaging interruption due to film exhaustion, ensuring the continuity of the packaging process, and reducing the problem of cable exposure or packaging rework caused by broken film. At the same time, the conductive ring triggering structure is simple, the manufacturing cost is low, and the subsequent maintenance only requires checking the conductive contact status, which is convenient for maintenance. As the slider 701 slides as the film thickness decreases, the connecting rod 702 synchronously pushes the piston disc 901 to move in the spray chamber 9 toward the side close to the infusion tube 807. The glue in the spray chamber 9 is squeezed and gradually pressed into the infusion tube 807. Since the infusion tube 807 adopts an expandable and contractible hose, it can adaptively expand and contract as the piston disc 901 moves, and will not interfere with the sliding of the slider 701 and the piston disc 901. It ensures that the detection and pre-glue pressing actions are carried out synchronously, and no additional power is required to drive the glue pressing. The glue pre-compression is completed synchronously by utilizing the sliding action of the detection mechanism, which simplifies the glue spraying power structure and reduces the energy consumption and failure probability of the equipment. When the second conductive ring 713 contacts the first conductive ring 712 and the circuit is connected, the solenoid valve of the glue spraying mechanism opens. Under the action of pressure, the glue previously squeezed into the first infusion tube 807 quickly flows through the first infusion tube 807 into the hollow rod 802, and is then atomized and sprayed onto the surface of the working film through multiple equidistantly arranged 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 uniform glue spraying, providing a stable bonding foundation for subsequent film splicing, and reducing glue waste. During this process, the spring 3 805 between the U-shaped frame 801 and the connecting plate 8 is always in a compressed state, and its elastic force pushes the U-shaped frame 801 to drive the hollow rod 802 and the roller 803 to fit closely to the surface of the film. 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 adjust their positions adaptively, so that the distance between the nozzle 806 and the film surface is always maintained at the optimal glue spraying distance, avoiding excessively thick, too thin or uneven glue spraying due to fluctuations in the distance, ensuring the consistency of the glue layer thickness, improving the sealing and firmness of the splicing, and at the same time, the roller 803 adopts a rolling contact method to avoid sliding friction with the film surface to cause scratches on the film, thereby protecting the integrity of the film and ensuring the packaging quality; When the second conductive ring 713 contacts the first conductive ring 712, the electromagnet 710 receives a trigger signal and is de-energized, and its magnetic attraction disappears. At this time, the previously compressed second spring 711 releases its elastic potential energy, generating a downward thrust, pushing the U-shaped plate 708 downward along the guide rod 1 707. The guide rod 1 707 provides a stable guide for the U-shaped plate 708, preventing the U-shaped plate 708 from deflecting during movement and causing dislocation of the splicing. During the downward movement of the U-shaped plate 708, the electrostatic adsorption roller 709 is driven to move downward synchronously, and the initial end of the standby state protective film adsorbed on its surface is accurately pressed onto the surface of the working state film sprayed with glue. Since the glue layer on the surface of the working film is uniform, the two are tightly attached under the pressing force of the electrostatic adsorption roller 709, and the glue quickly forms a bonding force to complete the seamless splicing of the two films. The rolling pressing method of the electrostatic adsorption roller 709 can make the splicing point evenly stressed, avoid weak bonding caused by insufficient local pressure, and realize automatic and precise splicing of the films, with high splicing efficiency and good sealing at the splicing point to prevent moisture and impurities from entering during transportation; The spliced ​​composite films continue to move with the rotating ring 103. When passing through the detection roller 703, the detection roller 703 performs a secondary flattening process on the splicing part under the thrust of the spring 1 705, eliminating the tiny gaps that may be generated by the splicing, further enhancing the bonding strength of the splicing part, ensuring that the splicing part will not crack or fall off during the subsequent packaging process, and improving the splicing quality.

[0024] After completing the packaging of the current cable, the equipment needs to be reset and materials replenished: the remaining protective film roll on the load-bearing shaft 2 604 (which has been converted to working status) is adjusted to the load-bearing shaft 1 6 for continued use, and then a new protective film roll is installed on the load-bearing shaft 2 604, and the debugging steps of the above preparation stage are repeated to prepare for the next cable packaging. This ending method can make full use of the remaining film and avoid material waste. At the same time, the standardized reset process can quickly complete equipment switching, improve material utilization, reduce packaging costs, and the equipment switching efficiency is high, which meets the needs of batch cable packaging.

[0025] It should be noted that both the infusion tube 1 807 and the infusion tube 2 903 are provided with a one-way valve.

[0026] 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, which is basically the same as Example 1, and further, a base plate 101 is equidistantly connected to a plurality of guide wheels 102 rotating around the axis of the rotating ring 103 as the center of a circle, and the guide wheels 102 are in contact with the outer wall of the rotating ring 103, and two driving shafts 2 are symmetrically connected to the base plate 101 for rotation, and pulleys are fixedly installed at both ends of the two driving shafts 2, and the two pulleys located on the rear side of the base plate 101 are connected by a second belt 202, and the two pulleys on the front side are connected by a first belt 201, and the first belt 201 is in contact with the outer wall of the rotating ring 103, and a tensioning wheel 203 is rotatably connected to the base plate 101, and the tensioning wheel 203 is against the first belt 201, and a motor 204 is fixedly installed on the base plate 101, and the driving shaft 2 is fixedly connected to the output end of the motor 204; Start motor 1 204, and the output torque of motor 1 204 is transmitted to the drive shaft 2 connected thereto through the coupling, and the pulleys at both ends of the drive shaft 2 rotate synchronously. Since the rear pulley is connected by belt 2 202, and the front pulley is connected by belt 1 201, the two drive shafts 2 will rotate synchronously in the same direction under the action of the belt transmission. At this time, belt 1 201, which is in contact with the outer wall of the rotating ring 103, generates movement under the drive of the drive shaft 2, and drives the rotating ring 103 to rotate around its own axis through the friction between belt 1 201 and the rotating ring 103. During the rotation of the rotating ring 103, the guide wheels 102 equidistantly arranged around it will roll with the movement of the rotating ring 103, and play a radial supporting and guiding role for the rotating ring 103, preventing the rotating ring 103 from radially deviating or shaking during the rotation process, thereby ensuring the stability of the rotation of the rotating ring 103, and further ensuring that the protective film on the bearing shaft can be evenly wrapped around the cable surface, thereby improving the packaging accuracy; When belt 201 becomes loose after being used for a period of time, the friction between it and the rotating ring 103 will decrease, and slipping may occur. At this time, the tensioning wheel 203 and the inner side of belt 201 can automatically or manually adjust the tension of belt 201 to ensure that belt 201 is always in close contact with the rotating ring 103 to avoid slipping, ensure the stability of power transmission, reduce the problem of packaging interruption caused by power transmission interruption, and improve the continuous working ability of the equipment. At the same time, a servo motor is selected as motor 204, and the motor speed can be accurately adjusted through the control system, thereby controlling the rotation speed of the rotating ring 103, realizing precise control of the winding speed of the protective film, adapting to cables with different diameters and different packaging requirements, and improving the versatility and flexibility of the equipment.

[0027] The drive mechanism includes rotating shafts 4 symmetrically connected to the base 1. Pulleys and friction rollers 401 are fixedly mounted on the two rotating shafts 4. The two pulleys are connected by a third belt 402. A second motor 404 is fixedly mounted on the lower end surface of the base 1. Pulleys are fixedly mounted on the output end of the second motor 404 and the rotating shafts 4. The two pulleys are connected by a fourth belt 403. The cable to be packaged is placed in the clamping space between the two friction rollers 401, and the second motor 404 is started. The output torque of the second motor 404 is transmitted to the rotating shaft 4 connected thereto through the fourth belt 403, and 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 with the drive of the third belt 402. At this time, the two friction rollers 401 rotate synchronously with the rotating shaft 4. The friction between the outer surface of the friction roller 401 and the outer wall of the cable drives the cable to rotate around its own axis. During the rotation of the cable, the protective film is wound in cooperation with the winding action of the rotating ring 103 to realize the spiral winding packaging of the protective film on the surface of the cable. The friction roller 401 adopts a rubber material with a high friction coefficient, which can increase the friction with the cable surface, ensure that the cable can be driven to rotate stably, avoid slipping, and ensure the stability of the cable rotation speed, so that the protective film is wound evenly, reducing the film overlap or excessive gap caused by unstable cable rotation speed, and improving the tightness and aesthetics of the cable packaging. At the same time, the motor 2 404 uses a reduction motor, which can provide a larger torque, can drive cables of different diameters to rotate, adapt to the packaging requirements of cables of different specifications, and improve the versatility of the equipment. In addition, the two symmetrically arranged friction rollers 401 play a certain clamping and positioning role on the cable, preventing the cable from axially offsetting during rotation, and further ensuring the packaging accuracy.

[0028] 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. The base plate 101 is symmetrically rotatably connected to rollers 503. Both rollers 503 are provided with pulleys. The two pulleys are connected by a belt 504. The two mounting plates 5 are connected to the belt 504 through a clamping plate. 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. 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 thereto to slide along the slide bar 502. Since the mounting plate 5 is fixedly connected to one side of the belt 504 through the clamping plate, the sliding of the mounting plate 5 drives the belt 504 to move along the roller 503, while the other mounting plate 5 is fixedly connected to the other side of the belt 504. Driven by the belt 504, the two mounting plates 5 will move synchronously toward 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 be in close contact with the outer wall of the cable, thereby clamping the cable; During the cable packaging process, when the driving mechanism drives the cable to rotate, friction will be generated between the cable and the clamping roller 501, driving the clamping roller 501 to rotate around its own axis. The rotation of the clamping roller 501 will not only not hinder the rotation of the cable, but also play an auxiliary guiding and positioning role for the cable, preventing the cable from radially jumping or axially offsetting 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, thereby improving the packaging accuracy and stability. At the same time, through the cooperation of the electric telescopic rod 505 and the belt five 504, the two mounting plates 5 can be adjusted synchronously to ensure the consistency of the adjustment, and the adjustment process has a high degree of automation, without the need for manual adjustment, reducing the difficulty of operation, improving the adaptability of the equipment, and being able to quickly adapt to the clamping requirements of cables of different diameters, reducing the equipment adjustment time, and improving the packaging efficiency. In addition, the clamping roller 501 is made of rubber material, which can clamp the cable while avoiding scratches or extrusion damage to the cable surface, thereby protecting the appearance quality of the cable.

[0029] The base plate 101 is provided with a chute, in which an adjustment block 3 is slidably connected. The adjustment block 3 is rotatably connected to a connecting shaft 301. The tensioning wheel 203 is fixedly mounted on the connecting shaft 301. A tensioning spring 303 is provided between the groove wall of the chute and the lower end surface of the adjustment block 3. The adjustment block 3 is provided with an adjustment groove 302. A fixing bolt 304 threadedly connected to the base plate 101 is inserted into the adjustment groove 302. When the equipment is working normally, the tensioning spring 303 is in a compressed state, and its upward elastic force pushes the adjusting block 3 to slide upward along the slide groove, driving the connecting shaft 301 and the tensioning wheel 203 to move upward synchronously, so that the tensioning wheel 203 is always tightly pressed against the inner side of the belt 1 201, providing continuous tension for the belt 1 201. When the belt 1 201 is stretched and relaxed due to long-term use, the pressure of the belt 1 201 on the tensioning wheel 203 is reduced, and the elastic force of the tensioning spring 303 pushes the adjusting block 3 to slide further upward, and the tensioning wheel 203 moves upward accordingly, increasing the degree of squeezing on the belt 1 201, thereby automatically compensating for the slack of the belt 1 201, maintaining the tension of the belt 1 201, avoiding the transmission slippage problem caused by belt relaxation, ensuring the stability of the rotation speed of the rotating ring 103, and thus ensuring the consistency of the cable packaging quality; When it is necessary to replace belt 101 or adjust the initial position of tensioner 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 downward, compress the tensioning spring 303, and drive the tensioner 203 to move downward, increasing the distance between the tensioner 203 and belt 101, making it convenient to disassemble or install belt 101. After the adjustment is completed, 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 slot 302, the adjusting block 3 is fixed in the slide groove to lock the position of the tensioner 203. This structure can not only automatically compensate for the slack of the belt, but also has a manual adjustment function, which is easy to operate, reduces the difficulty of equipment maintenance, reduces maintenance time, and improves the maintenance efficiency of the equipment.

[0030] Example 4: Reference Figure 8 、 Figure 9 、 Figure 10 A temporary packaging device for cable transportation is basically the same as Example 1. Furthermore, two tapered blocks 601 are sleeved on the first and second bearing shafts 604. The two tapered blocks 601 are respectively located on both sides of the protective film. The ends of the first and second bearing shafts 604 away from the rotating ring 103 are sleeved with locking rings 602 with notches. The locking bolts 603 are threadedly connected to the locking rings 602. When installing the protective film roll, first put the two conical blocks 601 on the load-bearing shaft 1 6 or the load-bearing shaft 2 604, and then put the protective film roll on the load-bearing shaft so that the protective film roll is located between the two conical blocks 601. The protective film roll is centered and positioned by the conical surface of the conical block 601 to prevent the protective film roll from radially offsetting on the load-bearing shaft, thereby ensuring the coaxiality of the protective film roll during rotation, and thus ensuring that the protective film can be evenly released, avoiding the problem of uneven film winding caused by the offset of the film roll, and improving the packaging quality.

[0031] After installing the protective film roll and the conical block 601, the locking ring 602 is sleeved on the end of the load-bearing shaft, and then the locking bolt 603 is tightened. The tightening force of the locking bolt 603 causes the notch of the locking ring 602 to shrink, and the inner wall of the locking ring 602 fits tightly with the outer wall of the load-bearing shaft, and the locking ring 602 is fastened to the load-bearing shaft. The locking ring 602 can play an axial limiting role on the conical block 601 and the protective film roll, preventing the conical block 601 and the protective film roll from falling off from the end of the load-bearing shaft during the rotation of the load-bearing shaft, thereby ensuring the safety and stability of the equipment operation.

[0032] When the protective film roll needs to be replaced after use, just loosen the locking bolt 603, and the notch of the locking ring 602 will return to its original state. Then, the locking ring 602 can be unscrewed from the load-bearing shaft, and then the used film roll and conical block 601 can be removed. Then, a new protective film roll can be installed according to the above steps. The replacement process is simple and convenient, without the need for complex tools, which reduces the film replacement time and improves the continuous working efficiency of the equipment.

[0033] The above description is merely a preferred embodiment of the present invention and does not limit the present invention in any form. Although the present invention has been disclosed as above with the preferred embodiment, it is not intended to limit the present invention.
