[0019] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0020] As shown in Figures 1 - 3, the extended limit structure 8 includes a circular frame 81 provided at one end of the driving rod 3, a hydraulic rod 82 provided inside the circular frame 81, a first rack 83 provided at the output end of the hydraulic rod 82, a first gear 84 meshed with one end of the first rack 83, a rotating rod 85 provided inside the first gear 84, a disc 86 provided at one end of the rotating rod 85, a groove 87 opened on the surface of the disc 86, a slider 88 slidably connected inside the groove 87, a sliding rod 812 provided at one end of the slider 88, a limiting plate 814 provided at one end of the sliding rod 812, and an opening 813 opened on the surface of the circular frame 81. The limiting plate 814 moves out of the outside of the opening 813. The diameter of the limiting plate 814 is greater than the diameter of the driving rod 3. The limiting plate 814 fits, presses and clamps the other end of the disc body 4 for positioning. The inner wall of the circular frame 81 is connected with a bottom plate. A notch is opened on the top surface of the bottom plate. A sliding block slides inside the notch. The sliding block is connected with the first rack 83. One end of the rotating rod 85 is connected with the inner wall of the circular frame 81 by a bearing. The other end of the rotating rod 85 is movably connected with a connecting column 89. The connecting column 89 is connected with the inner wall of the circular frame 81. A long connecting plate 810 is provided on the surface of the connecting column 89. Four groups of long connecting plates 810 are equally spaced. A chute 811 is opened on the surface of each of the four groups of long connecting plates 810. Four groups of sliding rods 812 are equally spaced. The four groups of sliding rods 812 slide inside the chute 811. The groove 87 is arc-shaped. The groove 87 is in a diffused state from the center of the disc 86 to the outside. The slider 88 slides from one end of the groove 87 close to the rotating rod 85 to the other end. The slider 88 drives the sliding rod 812 to move out of the circular frame 81. The slider 88 slides from one end of the groove 87 away from the rotating rod 85 to the other end. The slider 88 drives the sliding rod 812 to move inside the circular frame 81 to achieve the effect of precise positioning and pressing of the disc body 4.

[0021] Specifically, first, the staff passes the rod groove opened in the center of the disk body 4 through the surface of the driving rod 3, so that one end of the disk body 4 contacts the fixed plate 5 arranged on the surface of the driving rod 3, and four groups of clamping grooves 7 equally spaced on the surface of the disk body 4 are engaged with four groups of clamping blocks 6 equally spaced on the surface of the fixed plate 5 to fix the position of the disk body 4. Since a circular frame 81 is arranged at one end of the driving rod 3 away from the motor 2 and the diameter of the circular frame 81 is equal to the diameter of the driving rod 3, the disk body 4 can also pass through the circular frame 81 and be sleeved on the surface of the driving rod 3, and the circular frame 81 is not blocked by the disk body 4. Subsequently, the hydraulic rod 82 fixed to the inner wall of the circular frame 81 is started through an external button, and the hydraulic rod 82 drives the rack one 83 at the output end to move. The rack one 83 meshes with the gear one 84, and the gear one 84 drives the rotating rod 85 to rotate. One end of the rotating rod 85 is movably connected to the inner wall of the circular frame 81, and the rotating rod 85 drives the disk 86 to rotate. Thus, the sliders 88 inside the four groups of arc-shaped channels 87 equally spaced on the surface of the disk 86 slide from one end of the channel 87 close to the rotating rod 85 to the outside to the end away from the rotating rod 85, so that the sliders 88 drive the sliding rods 812 to slide outward in the sliding channels 811 opened on the surface of the long connecting plate 810. The long connecting plate 810 is connected to the connecting column 89, and the connecting column 89 is movably connected to the rotating rod 85. Thus, the four groups of sliding rods 812 drive the four groups of limiting plates 814 to move outward. Since the positions of the four groups of limiting plates 814 correspond to the four groups of openings 813 opened on the surfaces of the four groups of circular frames 81, further, the four groups of limiting plates 814 move out of the outside of the four groups of openings 813. Thus, the diameter of the four groups of limiting plates 814 is greater than the diameter of the driving rod 3. Further, the four groups of limiting plates 814 tightly press and clamp the other end of the disk body 4 for positioning, without the need for bolt fixation, which is convenient for operation. When the disk body 4 needs to be disassembled, only the hydraulic rod 82 needs to be driven in the reverse direction, so that the four groups of limiting plates 814 retract into the inside of the circular frame 81, realizing the precise positioning and pressing of the disk body 4, avoiding problems of deviation or dislocation, and improving the accuracy of positioning.

[0022] As shown in Figures 4 - 10 , the rack plate 1 is L-shaped, a cylinder 9 is arranged on the top surface of the rack plate 1, a support plate 10 is arranged at the top end of the cylinder 9, and a receiving frame 11 is arranged at the top end of the support plate 10, which is convenient for automatic material receiving.

[0023] A pushing disk structure 12 is arranged at the top end of the support plate 10. The pushing disk structure 12 includes a rack two 121 arranged at the top end of the support plate 10. One end of the rack two 121 meshes with a gear two 122. A screw rod 123 is arranged inside the gear two 122. One end of the screw rod 123 is movably connected to the rack plate 1. A threaded column 124 is threadedly connected to the surface of the screw rod 123. One end of the threaded column 124 is provided with a top plate 125, which is convenient for the separation and unloading of the disk body 4 wound around the surface of the driving rod 3.

[0024] On one side of the shelf board 1, there is an extension table 13. On one side of the extension table 13, there is a feeding structure 14. The feeding structure 14 includes a motor 141 arranged at one end of the extension table 13. At the output end of the motor 141, there is a rotating block 142. Inside the rotating block 142, there is a swinging rod 143 sliding. At one end of the swinging rod 143, there is a rotating seat 144. A spring 1411 is sleeved on the surface of the swinging rod 143. The two ends of the spring 1411 are respectively fixedly connected to the rotating block 142 and the rotating seat 144 to prevent the swinging rod 143 from falling off the rotating block 142. At one end of the rotating seat 144, there is a rotating shaft 145. At one end of the rotating shaft 145, there is a moving plate 146. On one side of the moving plate 146, there is a connecting plate 15. On one side of the extension table 13, there are two fixed plates 149 symmetrically arranged. Between the two fixed plates 149, there is a cross bar 1410. A collar 148 slides on the surface of the cross bar 1410. At the bottom end of the collar 148, there is a vertical rod 147. The moving plate 146 slides on the surface of the vertical rod 147 for automatic feeding, reducing the cost of manual feeding.

[0025] On one side of the connecting plate 15, there is a fixed shell 17. At the top end of the fixed shell 17, there is a clamping structure 16. The clamping structure 16 includes a servo motor 162 arranged inside the fixed shell 17. At the output end of the servo motor 162, there is a rotating rod 163. On the surface of the rotating rod 163, there is a gear three 164. At the upper and lower ends of the gear three 164, there are racks three 165 meshing respectively. At one end of the rack three 165, there is a connecting rod 166. At one end of the connecting rod 166, there is a clamping plate 167. The clamping plate 167 is arc-shaped. There are two groups of clamping plates 167 symmetrically distributed about the center axis of the fixed shell 17. The two groups of clamping plates 167 move in opposite directions. There is a long groove 168 opened on the top surface of the fixed shell 17. The connecting rod 166 moves in the long groove 168. There is an embedding groove opened on the inner wall of the fixed shell 17. Inside the embedding groove, there is a rectangular block sliding. The rectangular block is connected to the rack three 165, facilitating the stability of the disc body 4 on the placing plate 20.

[0026] At the top end of the connecting plate 15, there is a pushing structure 18. The pushing structure 18 includes a driven rod 181 arranged at one end of the rotating rod 163. The driven rod 181 passes through the inside of the rod groove opened on the surface of the connecting plate 15. One end of the driven rod 181 is movably connected to the inner wall of the connecting plate 15. One end of the connecting plate 15 is provided with a side plate 186. One end of the side plate 186 is movably connected to a lead screw 183. There is an annular belt 182 arranged between the lead screw 183 and the driven rod 181. A sleeve 184 is threadedly connected to the surface of the lead screw 183. The lead screw 183 drives the sleeve 184 to move along its axial direction towards the shelf board 1. At one end of the sleeve 184, there is a push plate 185 fixedly installed. The bottom end of the push plate 185 is flush with the top surface of the fixed shell 17. The automatic pushing operation is convenient and the degree of automation is high.

[0027] A placement plate 20 is provided at the top of the fixed housing 17. The placement plate 20 is used to place the disk body 4. A moving structure 19 is provided at the top of the fixed housing 17. The moving structure 19 includes driven plates 191 provided at both ends of the placement plate 20. A convex block 192 is provided at the bottom end of the driven plate 191. A long plate 193 is provided at the top of the fixed housing 17. A groove 194 is formed on the top surface of the long plate 193. The convex block 192 slides inside the groove 194. A tension spring 195 is provided at one end of the convex block 192. One end of the tension spring 195 is connected to the inner wall of the groove 194 to prevent it from falling during the feeding of the disk body 4.

[0028] Specifically, this device can also perform automatic clamping and feeding operations on the disk body 4. An extension table 13 is placed on one side of the mounting plate 1. A feeding structure 14 is provided on one side of the extension table 13. The staff can place the uncoiled disk body 4 on the surface of the placement plate 20 at the top of the fixed housing 17. Then, the servo motor 162 inside the fixed housing 17 is started by an external button. The servo motor 162 drives the rotating rod 163 at the output end. The rotating rod 163 drives the surface gear three 164 to mesh with the two racks three 165 at both ends. The two racks three 165 respectively drive the rectangular blocks at the bottom to slide in the embedding grooves formed on the inner wall of the fixed housing 17 in the opposite direction. The two racks three 165 respectively drive the connecting rods 166 at one end to move in the opposite direction. A long groove 168 is formed on the top surface of the fixed housing 17. The connecting rods 166 slide inside the long groove 168. The two connecting rods 166 respectively drive the arc-shaped clamping plates 167 connected to one end to move in the opposite direction to fix the disk body 4 on the placement plate 20. At this time, one end of the rotating rod 163 drives the driven rod 181 inside the connecting plate 15 to rotate forward. The driven rod 181 drives the lead screw 183 to rotate through the belt 182. The driven rod 181 is movably connected to the inner wall of the connecting plate 15. One end of the lead screw 183 is movably connected to the side plate 186. The side plate 186 is connected to the connecting plate 15. The lead screw 183 drives the sleeve 184 to move towards the side plate 186. Thus, the sleeve 184 drives the push plate 185 to move to one end of the fixed housing 17. At this time, the feeding of the disk body 4 is completed, and the next feeding step is required to improve the stability and accuracy during the feeding process.

[0029] Subsequently, an external button is used to drive a rotating block 142 connected to the output end by a motor 141 fixed on one side of the extension table 13 to slide on the surface of a swing rod 143. The rotating block 142 squeezes a spring 1411, and the rotating block 142 drives a rotating seat 144 to rotate. The rotating seat 144 drives a vertical rod 147, which is slidably connected inside a moving plate 146 connected by a rotating shaft 145, to move horizontally. Since the top end of the vertical rod 147 slides from right to left on the surface of a cross bar 1410 through a collar 148 until it is blocked by a set of fixed plates 149, as the swing rod 143 rotates, the moving plate 146 slides from the bottom end of the vertical rod 147 to the top end of the vertical rod 147. At the horizontal sliding end, a new disk body 4 is placed and fixed on a placing plate 20. Thus, the moving plate 146 drives a fixed shell 17 fixed at one end through a connecting plate 15 to slide along an L-shaped trajectory, first sliding horizontally and then vertically. Furthermore, the disk body 4 fixed at the top end of the fixed shell 17 is fed upward to be flush with the disk body 4 wound around the surface of a driving rod 3. This can achieve precise feeding of the disk body 4, ensure the accurate position of the disk body 4 on the placing plate 20, effectively utilize the space, and realize high efficiency in the feeding process.

[0030] Then, the disk body 4 wound around the surface of the driving rod 3 is detached from the surface of the driving rod 3. The hydraulic rod 82 inside a circular frame 81 is driven in the reverse direction by an external button, so that four sets of limiting plates 814 protruding from the surface of the circular frame 81 retract into the interior of the circular frame 81, and thus the disk body 4 is no longer blocked. Further, two cylinders 9 at the top of a support plate 1 are started by an external button to drive the support plate 10 at the top to move upward. The support plate 10 drives a receiving frame 11 at the top to move upward. At the same time, the support plate 10 drives two sets of second racks 121 at the top to move upward. The two sets of second racks 121 mesh with a second gear 122. The second gear 122 drives a screw rod 123 inside it to be threadedly connected with a threaded column 124. The screw rod 123 is movably connected to the support plate 1. The threaded column 124 drives a top plate 125 at one end to push the disk body 4 wound around the surface of the driving rod 3. Thus, the top plate 125 pushes the disk body 4 to move, and a clamping block 6 on a fixed plate 5 is separated from a clamping groove 7 formed on the surface of the disk body 4. The disk body 4 moves and slides over the circular frame 81, and thus falls into the interior of the receiving frame 11 below, completing automatic discharging and receiving. This realizes smooth and efficient discharging, can reliably collect the disk body 4 to a designated position, and ensures the smooth progress of subsequent processes.

[0031] Finally, the servo motor 162 inside the fixed housing 17 is reversely driven by an external button, causing the two sets of clamping plates 167 to move reversely away from the disc body 4 on the surface of the placement plate 20. Moreover, the rotating rod 163 moves reversely to drive the driven rod 181 to move reversely. The driven rod 181 drives the lead screw 183 to rotate reversely through the belt 182. The driven rod 181 is movably connected to the inner wall of the connecting plate 15, and one end of the lead screw 183 is movably connected to the side plate 186. The side plate 186 is connected to the connecting plate 15. The lead screw 183 drives the sleeve 184 to move in the direction of the driving rod 3. Thus, the sleeve 184 drives the push plate 185 to simultaneously push the placement plate 20 and the disc body 4, causing the placement plate 20 to drive the bumps 192 at the bottoms of the two end driven plates 191 to slide inside the grooves 194 formed on the surface of the long plate 193. The bumps 192 drive the tension springs 195 to stretch and store energy, causing the rod groove formed in the center of the disc body 4 to pass through the circular frame 81 and the surface of the driving rod 3. The card slot 7 on the surface of the disc body 4 is engaged with the card block 6 at one end of the fixed plate 5.
