[0031] In the description of this embodiment, the terms "upper", "lower", "right", etc., directions or positional relationships are based on the directions or positional relationships shown in the drawings, and are only for the convenience of description and simplification of operation, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as limiting the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0032] like Figures 1 to 5As shown, the cable reeling and unreeling device of the embodiment of the present invention comprises a mounting frame 1, a clamping mechanism and a winding mechanism, the clamping mechanism comprises a first U-shaped frame 2, an air guide tube 3, an air bag 4, a motor 6 and an inflatable assembly, the first U-shaped frame 2 is fixedly mounted on the mounting frame 1, two air guide tubes 3 are rotatably mounted in the first U-shaped frame 2, and the two air guide tubes 3 are spaced apart in the vertical direction (the vertical direction is the Z direction in the figure); an air bag 4 is sleeved on the outside of each air guide tube 3, the air bag 4 is communicated with the air guide tube 3, the two air bags 4 are spaced apart in the vertical direction, and a conveying groove 5 is arranged outside each air bag 4, the conveying groove 5 is annularly arranged around the rotation axis of the air bag 4, and the groove bottoms of the two conveying grooves 5 are spaced apart to form a clamping groove for clamping the cable; the motor The motor 6 is fixedly mounted on one side of the first U-shaped frame 2 along a first direction (the first direction is the X direction shown in the figure), and the driving shaft of the motor 6 is transmission-connected to one end of one of the air ducts 3 to drive the air duct 3 connected to the motor 6 to rotate; the inflation component is arranged on the side of the first U-shaped frame 2 away from the motor 6 along the first direction, and the inflation component is used to inflate the airbag 4 to deform the airbag 4 to form clamping grooves of different sizes to adapt to the clamping of cables of different diameters; the winding mechanism is arranged on the mounting frame 1, and the winding mechanism is located on one side of the clamping mechanism along the second direction (the second direction is the Y direction shown in the figure), and the winding mechanism can reel in or unreel the cable, wherein the first direction, the second direction and the vertical direction are arranged vertically.

[0033] It can be understood that by using the inflation component to inflate the two airbags 4 arranged at intervals to adapt to the clamping of cables of different wire diameters, the cable winding and unwinding operation is effectively guided and limited, and the occurrence of deviation and entanglement of the cable during the winding and unwinding process is reduced. It has high compatibility, simple operation, time-saving and labor-saving, and high economic benefits. By arranging the conveying groove 5 on the airbag 4, the position of the cable on the airbag 4 is effectively limited, the position accuracy of the cable conveyed on the airbag 4 is improved, and the groove walls on both sides of the conveying groove 5 along the first direction can be used to improve the wrapping of the cable; By inflating the airbag 4 to wrap and clamp the cables, the fit of the cables of different diameters is effectively improved, the contact area of ​​the cables is larger, and the clamping force of the airbag 4 on the cable sides is more balanced, thus avoiding deformation or damage of the cable due to excessive local clamping force; by rotating the airbag 4 and the air guide tube 3, the friction loss between the cable and the airbag 4 during the winding and unwinding process is effectively reduced, thereby ensuring the service life of the cable and the airbag 4, and the airbag 4 can be actively rotated by the motor 6, which can further reduce the wear of the cable and the airbag 4.

[0034] Furthermore, if Figure 3 , Figure 4 and Figure 5As shown, the inflation component includes an L-shaped tube 7, an air collecting box 9 and a drainage tube 10, the number of L-shaped tubes 7 is two, and each air guide tube 3 is movably connected to an L-shaped tube 7 on the side away from the motor 6 along the first direction, and each L-shaped tube 7 is provided with a first one-way exhaust valve 8; the air collecting box 9 is fixedly installed on the side of the first U-shaped frame 2 where the L-shaped tube 7 is provided, and a driving member is provided in the air collecting box 9, and the driving member is used to introduce the gas in the air collecting box 9 into the air guide tube 3 and the airbag 4 through the L-shaped tube 7; the drainage tube 10, the drainage tube 10 is fixedly inserted at the bottom of the air collecting box 9, and the bottom end of the drainage tube 10 is fixedly sleeved with an air delivery box 11, the ends of the two L-shaped tubes 7 away from the air guide tube 3 are respectively fixedly inserted on the bottom and side of the air delivery box 11, and the drainage tube 10 is provided with a second one-way exhaust valve 13.

[0035] During specific implementation, taking the winding of cables of different diameters as an example, firstly, one end of the cable is placed between the two conveying troughs 5, and then the driving component is started to make the gas in the air collecting box 9 flow to the air delivery box 11 through the drainage pipe 10, and then pass through the two L-shaped tubes 7 through the air guide pipe 3 to flow to the two air bags 4, so that the air bags 4 are expanded. Since the air bags 4 are uniform when expanded and the cross-section of the cable is circular, the cables of different diameters can be completely wrapped. Then, the motor 6 is turned on to rotate the two air guide pipes 3, and the cable can be conveyed, thereby achieving the effect of conveying different cables.

[0036] It should be noted that for the rotatable installation of the air guide tube 3, two sets of bearings can be fixedly installed on the first U-shaped frame 2, and the number of bearings in each set is two, and they are symmetrically installed. The two ends of each air guide tube 3 are respectively fixedly inserted in each set of two bearings, and can rotate normally. The L-shaped tube 7 is movably inserted in the air guide tube 3. Since the bearing is a prior art and is not a problem to be solved in the background technology of this specification, it will not be explained in detail in this specification.

[0037] Specifically, Figure 1 , Figure 4 and Figure 5As shown, the length of the air collecting box 9 extends along the second direction, and the driving member includes a piston plate 14 and an electric push rod 15. The piston plate 14 is slidably installed in the air collecting box 9, and the electric push rod 15 is fixedly installed on one side of the air collecting box 9 along the second direction. The driving end of the electric push rod 15 extends into the air collecting box 9 and is fixedly connected to the piston plate 14. A one-way air intake valve 12 is provided at one end of the air collecting box 9 away from the electric push rod 15 along the second direction, and a drainage pipe 10 is connected to one end of the air collecting box 9 away from the electric push rod 15 along the second direction. That is, the piston plate 14 is reciprocated by the extension and contraction of the driving end of the electric push rod 15. When the piston plate 14 slides toward the electric push rod 15, a certain negative pressure is formed on the side of the piston plate 14 and the air collecting box 9 away from the electric push rod 15, so that the external air is sucked into the air collecting box 9 through the one-way air intake valve 12; when the piston plate 14 moves in the direction away from the electric push rod 15, the piston plate 14 squeezes the space between the piston plate 14 and the side of the air collecting box 9 away from the electric push rod 15, so that the gas in the space of the air collecting box 9 is pushed to flow to the drainage tube 10, so as to reciprocate and expand the airbag 4. The structure of the driving member and the air collecting box 9 is simple, and the cost is lower than that of the air compressor and other structures, and the economic benefit is high.

[0038] Furthermore, if Figure 4 and Figure 5 As shown, the inflation assembly also includes a splitter plate 17, which is fixedly installed in the gas delivery box 11, and the splitter plate 17 divides the inner cavity of the gas delivery box 11 into a first air cavity 24 and a second air cavity 25. The first air cavity 24 is connected to an L-shaped tube 7, and the second air cavity 25 is connected to another L-shaped tube 7. The splitter plate 17 divides the air outlet of the drainage tube 10 into a first air outlet and a second air outlet. The first air outlet is connected to the first air cavity 24, and the second air outlet is connected to the second air cavity 25. Through the arrangement of the splitter plate 17, the gas introduced into the gas delivery box 11 by the drainage tube 10 can be evenly divided into two parts and transmitted to the two air bags 4 respectively, so as to ensure the uniformity of the inflation of the two air bags 4.

[0039] Optionally, a solenoid valve 16 is provided on one side of the airbag 4, and the solenoid valve 16 is used to connect the air inside the airbag 4 with the outside air. Through the provision of the solenoid valve 16, after the cable reeling and unwinding device completes the cable reeling and unwinding operation, the solenoid valve 16 can be automatically controlled to discharge the gas inside the airbag 4, so as to facilitate the next use of the cable reeling and unwinding device.

[0040] In some embodiments, Figure 1 and Figure 2As shown, the winding mechanism includes a motor 18 and a take-up roller 19. The take-up roller 19 is rotatably mounted on the mounting frame 1. The motor 18 is fixedly mounted at the bottom of the mounting frame 1. The driving shaft of the motor 18 penetrates the mounting frame 1 and is transmission-connected to the take-up roller 19. The rotation axis of the take-up roller 19 extends in the vertical direction. The motor 18 drives the take-up roller 19 to rotate to realize the cable winding and unwinding operation. At the same time, the length of the cable between the winding mechanism and the clamping mechanism can be controlled by controlling the speed of the motor 18 and the motor 6, so as to avoid the cable between the winding mechanism and the clamping mechanism being too tight to increase the friction loss between the cable and the airbag 4, or to avoid the cable between the winding mechanism and the clamping mechanism being too loose to affect the winding density of the take-up roller 19.

[0041] Furthermore, the cable reeling and winding device also includes an adjustment component, which is arranged on the mounting frame 1, and the adjustment component is located between the winding mechanism and the first U-shaped frame 2 along the second direction. The adjustment component includes a second U-shaped frame 20, a cylinder 21 and a fixed cylinder 22. The second U-shaped frame 20 is arranged on the mounting frame 1, the cylinder 21 is arranged on the top of the second U-shaped frame 20, and the fixed cylinder 22 is located in the second U-shaped frame 20. The cylinder 21 is connected to the fixed cylinder 22 in a transmission manner to drive the fixed cylinder 22 to move in a vertical direction, and the fixed cylinder 22 is provided for the cable to pass through. By using the cylinder 21 to push the fixed cylinder 22 to move, the height adjustment of the cable inserted in the fixed cylinder 22 and wound on the take-up roller 19 is realized, so as to avoid the cable being wound to the same position of the take-up roller 19 when winding, and improve the space utilization rate of the take-up roller 19.

[0042] In addition, in order to facilitate the counting of the length of the cable, we can install a roller counter at a suitable position on the mounting frame 1, and the length of the moving cable can be counted by the rotation of the take-up roller 19. For the roller counter, its working principle is mainly based on the interaction between the roller, gears and digital disk. Through the rolling of the roller and the transmission of the gear, the mechanical movement is converted into digital display to realize the counting function. Since the roller counter is a prior art and is not a problem that needs to be solved in the background technology of this specification, it will not be explained in detail in this specification.

[0043] Furthermore, the adjustment component also includes a ball 23, and a plurality of balls 23 are arranged at intervals on the inner wall of the fixed cylinder 22. The arrangement of the ball 23 can effectively reduce the friction loss between the cable and the fixed cylinder 22 during the transmission process, thereby ensuring the product quality of the cable.

[0044] like Figures 1 to 5 As shown, an embodiment of the present invention further provides an operation method of a cable reeling and unreeling device, using the above-mentioned cable reeling and unreeling device, comprising the following steps:

[0045] S10, passing the free end of the cable through the clamping groove formed by the two air bags 4 in the clamping mechanism of the cable reeling device, and winding the free end of the cable into the winding mechanism;

[0046] S20, starting the inflation component of the clamping mechanism to inflate the airbag 4 to deform it to clamp the cable;

[0047] S30, starting the winding mechanism to reel in the cable.

[0048] The cable winding method is simple to operate. By using the inflation component to inflate the two air bags 4 set at intervals to adapt to the clamping of cables of different wire diameters, the cable winding and unwinding operation is effectively guided and limited, and the occurrence of cable deviation and entanglement during the winding and unwinding process is reduced. The method has high compatibility, simple operation, and saves time and effort. The air bags 4 are inflated to wrap and clamp, which effectively improves the fit of cables of different wire diameters, makes the contact area of ​​the cable clamped larger, and the clamping force of the air bags 4 on the cable sides is more balanced, avoiding the deformation or damage of the cable caused by excessive local clamping force.

[0049] Furthermore, after step S30, step S40 is also included: starting and adjusting the motor 6 of the clamping mechanism to drive the air guide tube 3 and the air bag 4 to rotate, and adjusting the length of the cable between the clamping mechanism and the winding mechanism. The length of the cable between the winding mechanism and the clamping mechanism is controlled by controlling the speed of the motor 18 and the motor 6 of the winding mechanism, so as to avoid the cable between the winding mechanism and the clamping mechanism being too tight to increase the friction loss between the cable and the air bag 4 and the situation of winding tight, or to avoid the cable between the winding mechanism and the clamping mechanism being too loose to affect the winding density of the take-up roller 19.

[0050] Of course, when the winding mechanism is unwinding, the free end of the cable wound on the take-up roller 19 of the winding mechanism is removed and connected to the designated position through the clamping groove formed by the two air bags 4. The inflation component is started to inflate the air bag 4 to deform the air bag 4 and clamp the cable. Then the motor 18 of the winding mechanism and the motor 6 of the clamping mechanism are started to unwind in an orderly manner, which effectively improves the guide limit of the cable unwinding and reduces the random fluttering of the cable when unwinding.

[0051] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to list all the embodiments here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the claims of the present invention.
