[0038] like Figure 4 As shown, a net bag 131 is provided on the inner wall of the limit frame 122, and a nozzle 132 is provided on the inner wall of the limit frame 122 located at the net bag 131. A plurality of nozzles 133 are evenly arranged on the nozzle 132, and an output end of the nozzle 133 faces the net bag 131. A non-slip layer is provided on the surface of the net bag 131. A fan 135 is provided on the winding frame 3, and the nozzle 132 is connected to the output end of the fan 135. By driving the fan 135, air is blown toward the nozzle 132, and the wind from the nozzle 133 blows the net bag 131 to bulge, thereby reducing the space in the limit frame 122. When the wire bobbin 4 falls into the limit frame 122, it is instantly caught by the net bag 131, achieving the effect of slowing down the fall.

[0039] like Figure 5-Figure 6 As shown, a limit ring 911 is sleeved on the outer wall of the wire roller 2, and a plurality of slide rails 141 are arranged at intervals at the edge of the limit ring 911. A slider 142 is arranged in the slide rail 141 for sliding engagement. A clamping block 912 is arranged at one end of the slider 142, and the other end of the slider 142 is driven to slide by a driving mechanism.

The anti-slip teeth 143 can be arranged to increase the extrusion strength between the clamping block 912 and the end face of the wire drum 4 to ensure the stability of the clamping.

[0040] like Figure 7-Figure 8As shown, the driving mechanism includes a gear ring 162, a connecting strip 152 and a fixed ring 153. The fixed ring 153 is arranged at one end of the limiting ring 911 close to the first cylinder 8. The gear ring 162 is rotatably arranged on the fixed ring 153. The two ends of the connecting strip 152 are respectively hinged to the gear ring 162 and one end of the slider 142.

[0041] The winding frame 3 is provided with a base frame 161, on which two main gears 163 meshing with a gear ring 162 are rotatably provided. The two main gears 163 are linked by a telescopic shaft, and the main gears 163 are driven to rotate by a third motor 164. A gear sleeve 165 meshing with the gear ring 162 is slidably provided on the outer side of the first cylinder 8, and the gear sleeve 165 is connected to the winding frame 3 through the third cylinder 166. A tooth plate 167 is respectively provided on the winding frame 3 and the gear ring 162, and a first gear 168 is meshed between the two tooth plates 167.

When rotating, the connecting strip 152 tends to be horizontal, and at this time the slider 142 pulls the clamping block 912 close to the bobbin 4 for clamping. When the clamping is stable, the main gear 16 is paused. 3 rotates, the piston rod of the third cylinder 166 extends out, pushing the gear sleeve 165 to be sleeved on the gear ring 162. During the movement process, the gear plate 167 moves, driving the first gear 168 and the other gear plate 167 to move accordingly, so that the main gear 163 and the gear sleeve 165 move synchronously in the opposite direction. When the gear sleeve 165 and the gear ring 162 are sleeved, the main gear 163 is separated from the gear ring 162 to limit the rotation angle of the gear ring 162. Specifically, only a bracket is slidably provided on the base frame 161, a group of main gears 163 are provided with two and mesh with each other, and the two main gears 163 are arranged on the base frame 161 through the bracket, and the main gear 163 is rotatably connected with the end face of the base frame 161.

[0042] like Fig. 9 As shown, two hinged bars 915 form a group, and the end faces of the two hinged bars 915 are hingedly arranged. A plurality of support bars 173 are arranged on the inner wall of the wire roller 2. The support bar 173 is arranged to slide with the outer wall of the central axis 914 at one end away from the wire roller 2. The hinged bars 915 are hingedly arranged with the side wall of the central axis 914 and the end of the support bar 173 close to the central axis 914 at one end away from each other. The end faces of the two hinged bars 915 are hingedly provided with push blocks 171, which penetrate the side groove 913 and extend outward. The end face of the central axis 914 extends out through the piston rod of the fourth cylinder 172. The central axis 914 is driven to slide by the fourth cylinder 172, and the two hinged bars 915 of each group are squeezed close to each other. At this time, the push blocks 171 on the end faces of the hinged bars 915 extend out of the side groove 913 and fit tightly with the inner wall of the wire drum 4 to achieve a supporting effect.

[0043] A clamping groove 181 and a clamping block 182 are respectively disposed at opposite ends of the two clamping shafts 916 , and the clamping groove 181 and the clamping block 182 are clamped with each other.

[0044] Working principle: before the winding operation, multiple empty wire bobbins 4 are placed steadily in the limiting groove 121 on the feeding conveyor belt 6 in advance, and the two first cylinders 8 are contracted to drive the two wire rollers 2 to move away from each other, and the feeding conveyor belt 6 is driven to rotate, driving a wire bobbin 4 to fall into the limiting frame 122, and smoothly fall onto the bracket 7 through the limiting frame 122. At this time, the wire bobbin 4 and the central axis of the two wire rollers 2 are in the same straight line, and the first cylinder 8 drives the two wire rollers 2 to penetrate the two ends of the wire bobbin 4 at a uniform speed until the two limiting rings 911 are against the end faces of the wire bobbin 4, and the multiple clamping blocks 912 on the limiting rings 911 drive the end faces of the wire bobbin 4 to clamp and fix them, and the wire bobbin 4 and the wire roller 2 are initially fixed, and then the central axis 914 is driven to drive the multiple hinged strips 915 to be hinged and bent, and the bent part extends out of the side groove 913 and is tightly against the inner wall of the wire bobbin 4. Due to the distribution of the hinged strips 915 in the wire bobbin 4 The bobbin 4 is relatively uniform and can effectively avoid deformation and damage of the bobbin 4 due to excessive pressure on a certain part of the bobbin 4 during the support process. After the installation is completed, the bracket 7 is separated from the bobbin 4, the material roller conveyor body 1 is started, and the end faces of the built-in coil and the insulating tape are wound on the bobbin 4. The second motor 10 is driven during the winding process to drive the wire roller 2 and the bobbin 4 to rotate to achieve uniform winding operation. After the winding is completed, the material is unloaded and the bracket 7 is re-placed under the two ends of the bobbin 4 to support it. Then, the support for the bobbin 4 on the wire roller 2 is completely withdrawn and the first cylinder 8 is contracted, so that the bobbin 4 is completely separated from the wire roller. At this time, the bracket 7 is rotated toward the side of the unloading conveyor belt 5, and the bobbin 4 is stably placed on the unloading conveyor belt 5. The unloading conveyor belt 5 is driven to rotate, and the bobbin 4 is transferred to another place for storage. After the bracket 7 rotates and resets, the loading conveyor belt 6 is driven to rotate to load the empty bobbin 4, and the above steps are repeated.

Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
