The top of the placement plate 1 is located on one side of the vertical plate and is provided with a slidable mounting frame 2. The mounting frame 2 is symmetrically arranged along the center of the placement plate 1. A circular frame 3 is slidably connected in the mounting frame 2. A conveying roller 4 for conveying cables is rotatably arranged in the circular frame 3.

The bottom of the toothed disc 8 is transmission-matched with a toothed plate 13. The toothed plate 13 is transmission-connected to the conveying roller 4 at one end close to the mounting frame 2. When the conveying roller 4 rotates, the conveying roller 4 drives the toothed plate 13 to move in the direction of the mounting frame 2. When the toothed plate 13 moves in the direction of the mounting frame 2, the toothed plate 13 prompts the toothed disc 8 to rotate.

[0034] Please refer to Figure 1 Preferably, the outer diameter of the chuck 10 is adapted to the inner diameter of the wire roller 7, the mounting frame 2 is arranged in a "U"-shaped structure, the conveying roller 4 is arranged in the mounting frame 2, and the top of the placement plate 1 is symmetrically fixedly installed with a fixing block 6 along the center, and the two groups of fixing blocks 6 are arranged on the side relatively far away from the two groups of mounting frames 2, and the two ends of the fixing block 6 are rotatably connected with a screw rod 5, and the screw rod 5 is rotatably matched with the end of the mounting frame 2. It should be noted that: the screw rod 5 passes through the ends of the two groups of mounting frames 2 and the ends of the two groups of fixing blocks 6, and an annular groove is formed between the screw rod 5 and the fixing block 6. It is rotatably connected to the annular plate, and the fixed block 6 has a limiting and guiding effect on the screw rod 5, and one group of screw rods 5 is matched with the two groups of mounting frames 2 through threaded rotation, that is, one group of screw rods 5 is symmetrically provided with two groups of opposite screw tooth structures along the center, and the two groups of mounting frames 2 are respectively provided with corresponding screw grooves matching therewith. When in use, when one group of screw rods 5 rotates, the two groups of mounting frames 2 are relatively far away or relatively close, thereby driving the conveying rollers 4 to move, so as to adjust the distance between the two groups of conveying rollers 4 to adapt to cables of different specifications.

[0035] Preferably, a fixed shaft is fixedly provided at the center of the conveying roller 4, and a driving device is slidably installed on the top of the mounting frame 2, and the top end of the fixed shaft protrudes from the top of the conveying roller 4 and is transmission-connected to the driving device. In this way, the fixed shaft can be driven to rotate by the driving device, and the rotation of the fixed shaft drives the conveying roller 4 to rotate. The circular frame 3 is elastically connected to the mounting frame 2, and the fixed shaft is rotatably connected to the side wall of the circular frame 3. The top side wall of the mounting frame 2 is provided with a first through groove for the top end of the fixed shaft to slide, and a transmission groove is provided at the top center of the placing plate 1, and the transmission groove is provided between the two groups of fixed blocks 6. The bottom end of the fixed shaft protrudes from the bottom of the conveying roller 4 and extends into the transmission groove. A second through groove is provided on the bottom side wall of the mounting frame 2 that is slidably connected to the bottom end of the fixed shaft, and the bottom end of the fixed shaft is transmission-connected to the toothed plate 13; the driving device can be a servo motor commonly used in the prior art for driving the fixed shaft to rotate, and the specific structure and working principle will not be described in detail here.

[0036] In actual use, the circular frame 3 can only slide horizontally in the mounting frame 2. When the wire roller 7 wound with the cable is installed and fixed between the two sets of vertical plates by the clamp 10 in the initial state, and the end of the cable spread out from the wire roller 7 is below the wire roller 7, and the conveying roller 4 is at the end of the mounting frame 2 away from the vertical plate under the elastic action between the circular frame 3 and the mounting frame 2, the tooth plate 13 is engaged with the bottom of the toothed disc 8 at one end close to the mounting frame 2, and then the spread end of the cable passes through the two sets of conveying rollers 4, and then the two sets of conveying rollers 4 are adapted to the size of the cable by rotating the screw rod 5, and then the driving device is started to rotate the conveying roller 4 through the fixed shaft, and the rotation of the conveying roller 4 will pull the cable out of the wire roller 7. At this time, since a large pulling force is required in the initial stage of the cable being spread out from the wire roller 7, and the conveying roller 4 There is space on the mounting frame 2 to move toward the line roller 7, so when the conveying roller 4 rotates, it will first move toward the line roller 7 on the cable surface, and then the circular frame 3 will move in the direction of the line roller 7 in the mounting frame 2. When the circular frame 3 cannot move in the mounting frame 2, the rotation of the fixed shaft will pull the tooth plate 13 to move in the direction of the mounting frame 2, and then the chuck 10 will be driven to rotate through the action of the toothed disc 8, and the rotation of the chuck 10 will drive the line roller 7 to rotate. At this time, the rotation direction of the line roller 7 is the direction in which the cable is spread out on the line roller 7, so that when the cable is initially spread out from the line roller 7, the toothed plate 13 drives the line roller 7 to rotate through the cooperation of the toothed disc 8 and the chuck 10 under the action of the fixed shaft, so as to avoid the cable from initially spreading out from the line roller 7, and the line roller 7 is rotated by transmitting the tension through the cable itself, which causes the problem of damage to the cable.

In this way, in actual use, the toothed plate 13 can be elastically reset by itself through the action of the elastic telescopic column when it is not subjected to the tension of the fixed shaft; in addition, when the toothed plate 13 moves in the groove 16 toward the mounting frame 2 under the action of the fixed shaft, the end of the toothed plate 13 away from the mounting frame 2 is separated from the toothed disc 8, thereby avoiding the problem that the toothed disc 8 is stuck after the toothed plate 13 stops moving after the toothed plate 13 moves and drives the toothed disc 8 to rotate.

When the chuck 10 and the line roller 7 are adapted, the rotation of the chuck 10 can drive the line roller 7 to rotate, and the stopping of the rotation of the chuck 10 can stop the line roller 7.

[0039] See also Figure 3-Figure 6 Preferably, a reset plate 12 is slidably connected to the tooth plate 13 on one side close to the vertical plate. The reset plate 12 is slidably arranged in the groove 16, and a spring is arranged between the bottom of the reset plate 12 and the groove 16. A bellows 106 is fixedly arranged at the top center of the reset plate 12. The bellows 106 is slidably arranged in the side wall of the vertical plate, and a spring is arranged between the top of the bellows 106 and the inner wall of the vertical plate. It should be noted that the spring force at the top of the bellows 106 is greater than the spring force at the bottom of the reset plate 12, and the length of the reset plate 12 is slidably adapted to the length of the groove 16, so that the reset plate 12 can only slide in the vertical direction in the groove 16.

[0040] Preferably, the end of the reset plate 12 close to the mounting frame 2 is slidably matched with the limit plate 17, see Figure 7As shown, the limit plate 17 is elastically connected to the side wall of the placement plate 1 via a spring, so that when the top of the reset plate 12 is flush with the top of the placement plate 1, the end of the limit plate 17 can extend into the reset plate 12, and when the limit plate 17 is separated from the reset plate 12, the reset plate 12 can move downward but will not pass over the end of the limit plate 17, that is, after the reset plate 12 moves downward, the end of the reset plate 12 still slides and fits with the end of the limit plate 17.

[0041] Further, preferably, an air cavity 101 is arranged in a circular array along the center of the periphery of one end of the chuck 10 close to the line roller 7, a piston 103 is elastically connected to the air cavity 101 through a spring, a first air channel 102 connected to the air cavity 101 is arranged in the center of the chuck 10, a transmission ring 104 is rotatably connected to the periphery of the sliding disk, an end of the first air channel 102 away from the air cavity 101 is connected to the transmission ring 104 through a second air channel, the second air channel is arranged in the side wall of the chuck 10 and the sliding disk, and the bottom periphery of the transmission ring 104 is fixed An air pipe 105 is fixedly provided, and one end of the air pipe 105 away from the transmission ring 104 extends into the bellows 106. In actual use, a section of the air pipe 105 close to the bellows 106 is made of rigid material, and its outer periphery is fixedly connected to the side wall of the vertical plate, so that the bellows 106 can be guided and supported, while a section of the air pipe 105 close to the transmission ring 104 is made of flexible material and slidably fits with the side wall of the vertical plate. When the sliding disk slides in the direction away from the line roller 7, the length and material of the air pipe 105 are sufficient to meet its sliding requirements.

[0042] See also Figure 9-11 Preferably, a winding drum 201 is slidably provided on the outer periphery of the bottom end of the fixed shaft, a second telescopic plate is provided between the two sets of fixed shafts, the bottom of the second telescopic plate is rotatably connected to the winding drum 201, a pull rope 18 is fixedly provided on the winding drum 201, the end of the pull rope 18 away from the winding drum 201 passes through the side wall of the placement plate 1 and is fixedly connected to the tooth plate 13, and a round rod 202 extending into the transmission groove is fixedly provided at one end of the bottom of the mounting frame 2 near the line roller 7, and the end of the pull rope 18 away from the winding drum 201 passes around the round rod 202 and is fixedly connected to the tooth plate 13, When in use, a first tooth is arranged in a circular array along the center of the winding drum 201 at the bottom end of the inner ring side wall of the winding drum 201, and a second tooth is fixedly arranged on the periphery of the fixed shaft to slide with the first tooth, and the height of the first tooth is equal to one third of the height of the inner ring side wall of the winding drum 201. In the initial state, the first tooth and the second tooth are in an staggered meshing state, so that when the fixed shaft rotates, the fixed shaft drives the winding drum 201 to rotate, and the rotation of the winding drum 201 forms the winding of the pull rope 18, thereby causing the tooth plate 13 to move toward the direction of the mounting frame 2.

[0043] The inner wall of the placing plate 1 is provided with movable grooves on both sides of the transmission groove, and the movable groove is connected to the transmission groove, and a separation plate 171 is elastically connected to the end of the movable groove away from the fixed axis, and a first telescopic plate 172 is slidably connected to the side of the separation plate 171 close to the fixed axis, and the first telescopic plate 172 is fixedly connected to the second telescopic plate, and the end of the limiting plate 17 away from the reset plate 12 is slidably matched with the separation plate 171. Preferably, the separation plate 171 can only slide in the movable groove in the vertical direction, and the end of the limiting plate 17 close to the separation plate 171 is provided with an inclined surface facing the separation plate 171. In the initial state, the end of the limiting plate 17 close to the separation plate 171 is flush with the inner wall of the movable groove, and the end of the limiting plate 17 away from the separation plate 171 extends into the reset plate 12 to limit it. The top height of 171 is lower than the height of the uppermost end of the inclined surface of the limiting plate 17. Under the action of the spring between the separating plate 171 and the movable groove, the first teeth and the second teeth of the winding drum 201 are staggered and meshed, that is, the winding drum 201 is connected with the fixed shaft in a transmission manner. When the tooth plate 13 moves to push the limiting plate 17 to move away from the reset plate 12, the limiting plate 17 first releases the limit on the reset plate 12, and then the end of the limiting plate 17 away from the reset plate 12 extends into the movable groove, and the separating plate 171 moves downward through the action of the inclined surface, and then the first telescopic plate 172 and the second telescopic plate are used to realize the downward movement of the winding drum 201, so that the first teeth and the second teeth are separated, so that the winding drum 201 has the conditions for free rotation, and then the tooth plate 13 can achieve the effect of automatic reset.

[0044] In specific use, after the wire roller 7 is installed and fixed between the two sets of vertical plates by the cooperation of the positioning assembly 11 and the chuck 10, the piston 103 shrinks in the air cavity 101 under the sliding cooperation with the inner wall of the wire roller 7, so that the gas in the air cavity 101 is transported to the transmission ring 104 through the first air channel 102 and the second air channel, and then transported to the bellows 106 through the air pipe 105, so that the bellows 106 expands upward, so that the corresponding spring above the bellows 106 is forced to shrink, and in the initial state, the reset plate 12 is in the limit position. The limit plate 17 is in a position flush with the top of the placement plate 1, so that the tooth plate 13 is meshed with the toothed disc 8. In this way, when the cable is transported, the tooth plate 13 will move toward the mounting frame 2 to cause the toothed disc 8 to rotate, thereby avoiding the problem of possible damage to the cable. When the tooth plate 13 moves to the end of the groove 16 and the end of the tooth plate 13 away from the mounting frame 2 is no longer meshed with the toothed disc 8, the end of the tooth plate 13 close to the mounting frame 2 acts on the limit plate 17 to move away from the reset plate 12 and separate from the reset plate 12, so that The reset plate 12 releases the limit, and the corresponding spring above the bellows 106 pushes the bellows 106 to move downward, thereby causing the reset plate 12 to move downward, and the reset plate 12 moves downward so that the tooth plate 13 moves downward, and the tooth plate 13 moves downward and separates from the toothed disc 8. When the limit plate 17 is pushed by the reset plate 12, the limit plate 17 realizes the downward movement of the winding disc 201 through the action of the separation plate 171, the first telescopic plate 172, and the second telescopic plate, so that the first tooth and the second tooth are separated, and then the tooth plate 13 moves downward under the corresponding elastic action. The bellows 106 on the top of the reset plate 12 is in an expanded state, so the toothed plate 13 will not move upward to reset and mesh with the toothed disc 8 again. Only when the cable on the line roller 7 is laid out and the line roller 7 is removed from between the vertical plates and the piston 103 is moved and reset, the bellows 106 will shrink and reset, thereby causing the reset plate 12 to move and reset, and the reset plate 12 moves and resets, causing the limit plate 17 to move and reset, and then the separation plate 171 and the winding reel 201 move and reset, ready for next use.

[0046] In actual use, in the initial state, the first elastic telescopic tube 20 is in a contracted state, the second elastic telescopic tube 22 is in an expanded state, the first deceleration plate 14 and the second deceleration plate 15 are slidingly fitted with the side walls of the toothed disc 8. At this time, since the first deceleration plate 14 and the second deceleration plate 15 are fitted with the toothed disc 8, the friction force is increased for the rotation of the toothed disc 8, making it difficult for the toothed disc 8 to rotate. When the conveying roller 4 moves toward the line roller 7, the fixed shaft squeezes the second elastic telescopic tube 22, so that the gas in the second elastic telescopic tube 22 is transported to the first elastic telescopic tube 20 through the connecting tube 21, thereby prompting the first elastic telescopic tube 20 to extend and extend, thereby causing the second deceleration plate 15 to move into the housing 9, and through the action of the gear 19, the first deceleration plate 14 is moved away from the toothed disc 8, thereby achieving the effect of separating the first deceleration plate 14 and the second deceleration plate 15 from the toothed disc 8, that is, the first deceleration plate 14 and the second deceleration plate 15 are separated from the toothed disc 8. The plate 15 no longer exerts a force on the toothed disc 8, thereby reducing the energy consumption of the driving device. When the cable is completely spread out on the line roller 7, the line roller 7 needs to be removed. In order to prevent the line roller 7 from continuing to idle due to inertia after the cable is spread out, the conveying roller 4 and the fixed shaft will move and reset after the cable is completely spread out from the line roller 7, thereby allowing the second elastic telescopic tube 22 to elastically reset. The reset of the second elastic telescopic tube 22 will allow the gas in the first elastic telescopic tube 20 to be transported to the second elastic telescopic tube 22 through the connecting tube 21, and then the first elastic telescopic tube 20 will elastically reset. The reset of the first elastic telescopic tube 20 drives the second deceleration plate 15 to move and reset through the baffle, and then the first deceleration plate 14 is moved and reset through the gear 19, thereby achieving the effect of quickly stopping the toothed disc 8 after being fitted with the toothed disc 8. When the toothed disc 8 stops, the line roller 7 immediately stops rotating, thereby facilitating the unloading work of the line roller 7.
