The bottom ends of the two clamping plates 12715 are provided with anti-skid pads 12716, and the anti-skid pads 12716 are made of rubber.

[0032] The unloading assembly 2 includes a support seat 21 installed on the top of the working frame 11, a laser rangefinder 22 is installed on the internal top of the support seat 21, support frames 23 are installed on both ends of the rear side of the support seat 21, unloading cylinders 24 are installed on one side of the two support frames 23, and unloading plates 25 are installed on the telescopic ends of the two unloading cylinders 24. Through grooves 26 are opened at both ends of the interior of the support seat 21, and a pressure sensor 27 is provided on one side of one of the through grooves 26. A mounting frame 28 is installed inside the support seat 21, and a plurality of groups of sliding rods 29 are connected to the interior of the mounting frame 28. A push plate 210 is commonly installed at one end of each sliding rod 29, and a pressing plate 211 is installed at the other end of each sliding rod 29. A plurality of groups of springs 212 are installed on one side of the exterior of the mounting frame 28, and the springs 212 are located outside the sliding rods 29, and one end of the springs 212 is connected to the pressing plate 211.

[0033] The material passes through the two material ports 12712 for winding, the first motor 19 drives the first pulley 110 to rotate clockwise, the first pulley 110 drives the double-layer pulley 111 to rotate synchronously through the first synchronous belt 112, at this time the winding wheel 14 and the winding wheel 2 15 rotate synchronously; a plurality of groups of connecting shafts 16 are placed on the top of the guide inclined plate 12 and lined up to carry out the winding work, at this time the telescopic ends of the two micro cylinders 13 are in an extended state to prevent the connecting shafts 16 from falling and play a blocking role, when the material needs to be wound, the piston rods of the two micro cylinders 13 are retracted, so The guide inclined plate 12 is an inclined surface, so that the first connecting shaft 16 in the waiting position rolls downward to contact the material. Since the surface of the winding core shaft 17 is wound with double-sided tape, the material is adhered to the surface of the winding core shaft 17. Since the winding wheel 14 and the winding wheel 2 15 rotate at the same speed and in the same direction, the top winding core shaft 17 is driven to rotate at this time, and the material is located on the surface of the winding core shaft 17 for winding. As time goes by, the rolled material becomes larger and larger; when the laser rangefinder 22 detects that the number of meters of the material roll reaches the preset value, the laser rangefinder 22 simultaneously notifies the second electromagnet 115, the second motor 1272 and the electric push rod 12713;

[0034] Since the slider 116 is an iron block, when the second electromagnet 115 is started, the slider 116 moves toward the second electromagnet 115 and is fixed. At this time, the second synchronous belt 120 is tightly fitted with the double-layer pulley 111 and the second pulley 119 respectively. When the double-layer pulley 111 rotates, the second synchronous belt 120 drives the second pulley 119 and the half gear 118 to rotate. At this time, the teeth of the half gear 118 are meshed with the lower teeth 123. The half gear 118 drives the connecting frame 121 located on the outer side of the working frame 11 to move toward the winding core shaft 17. The connecting frame 121 is connected to the mounting plate 126. The cutting assembly 127 is driven to move, and the two ends of the mounting seat 1271 are located inside the two through slots 26 to slide, so that the moving speed of the cutting assembly 127 is the same as that of the coiled material. At the same time, the second motor 1272 and the electric push rod 12713 are also operated at the same time. The telescopic end of the electric push rod 12713 drives the top plate 12714 to move downward. At this time, the top plate 12714 drives the clamping plates 12715 at the two ends of the bottom to move downward at the notch 12711, clamping and fixing the two ends of the material, and the cutting knife 1279 is located in the middle of the materials at the two ends of the clamping, so as to facilitate the cutting of the rolled material;

[0035] When cutting, the power driving end of the second motor 1272 drives the driving gear 1273 to rotate, the driving gear 1273 drives the driven gear 1275 to rotate, and the screw rod 1274 is located inside the mounting seat 1271 and rotates. At this time, the limit rod 1278 is set to make the moving seat 1276 inside the mounting seat 1271 move linearly, and the moving seat 1276 drives the cutting knife 1279 to move and cut the clamped material. The moving speed of the cutting knife 1279 is the same as that of the coil.

[0036] When the cutting is completed, the second motor 1272 drives the driving gear 1273 to rotate in the opposite direction to reset the cutting knife 1279; at this time, the teeth of the half gear 118 are disengaged from the lower teeth 123 and meshed with the upper teeth 122, and the connecting frame 121 moves in the opposite direction, and the connecting frame 121 drives the cutting assembly 127 to move in the opposite direction through the mounting plate 126. When one side of the mounting seat 1271 squeezes the pressure sensor 27 on one side of the inner side of the through groove 26, the pressure sensor 27 senses the change in pressure, and at this time, signals are sent to the first electromagnet 114 and the second electromagnet 115 respectively, the magnetic force of the second electromagnet 115 disappears, the first electromagnet 114 starts, and the slider 116 is located in the slide groove 113 by the magnetic force and moves toward the first electromagnet 114, so that the second pulley 119 is in a loose state, and the double-layer pulley 111 cannot drive the second pulley 119 to rotate through the second synchronous belt 120, and the cutting assembly 127 is in a stopped state;

[0037] When the laser rangefinder 22 detects that the number of meters of the material roll reaches a preset value, the slider 116 and the second electromagnet 115 are attracted to each other, and the double-layer pulley 111 drives the second pulley 119 to rotate through the second synchronous belt 120; when one side of the mounting seat 1271 squeezes the pressure sensor 27 on one side of the through groove 26, the slider 116 and the first electromagnet 114 are attracted to each other, and the double-layer pulley 111 cannot drive the second pulley 119 to rotate through the second synchronous belt 120;

[0038] Embodiment 2

[0039] like Figures 1 to 9 In the second embodiment, other structures remain unchanged. The difference from the first embodiment is that the cutting assembly 127 moves synchronously with the rolled material during operation. When the cutting assembly 127 squeezes the push plate 210, the push plate 210 drives the pressing plate 211 to move toward the rolled material through a plurality of sets of slide bars 29, so that the pressing plate 211 presses the rolled material. The plurality of sets of springs 212 are in an elongated state. When the pressing plate 211 applies pressure to the rolled material, the edge of the cut material after rolling can be prevented from warping, thereby improving the quality of the rolled material. When the cutting assembly 127 is separated from the push plate 210, the pressing plate 211 is separated from the rolled material through the setting of the plurality of sets of springs 212.

[0040] After the coil is rolled and cut, when it needs to be unloaded, the unloading cylinder 24 is started, and the unloading plate 25 installed at the telescopic end of the unloading cylinder 24 moves backward, and the unloading plate 25 pulls the two ends of the connecting shaft 16 (the unloading plate 25 is not in the same horizontal plane as the winding core shaft 17 that is being rolled, so as to prevent the winding work of the winding core shaft 17 from being affected), and the unloading plate 25 moves the finished product winding core shaft 17 to one side for unloading; a trolley is set at the position where the finished product winding core shaft 17 is unloaded, and the coil is collected by the trolley;

[0041] When the laser rangefinder 22 detects that there is no connecting shaft 16 on the top of the take-up wheel 14 and the take-up wheel 2 15, the piston rods of the two micro cylinders 13 retract. Since the guide ramp 12 is an inclined surface, the first connecting shaft 16 in the waiting position rolls down and contacts the cut material. Since the surface of the new winding core shaft 17 is wrapped with double-sided tape, the material is adhered to the new winding core shaft 17. The winding core shaft 17 that is in the winding operation rolls between the winding wheel 14 and the winding wheel 2 15 to start the winding operation of the new material roll.
