[0041] The winding assembly includes a winding shaft 201 rotatably mounted on the wall panel 100, a winding rod 202 connected to the end of the winding shaft 201, a bearing 203 sleeved on the winding shaft 201, and a winding cylinder 204 installed on the wall panel 100. The end of the winding rod 202 away from the winding shaft 201 forms a fork 205 coaxial with the winding shaft 201. The bearing 203 is sleeved on the winding shaft 201 through an inner ring and is connected to the power end of the winding cylinder 204 through an outer ring. The power output direction of the winding cylinder 204 is parallel to the winding shaft 201. The winding drive mechanism includes a winding motor 301 installed on the wall panel 100 and a rotating sleeve 302 mounted on the winding shaft 201.

In this way, the single-station automatic winding device of the bag-making machine provided in this embodiment can automatically complete the winding process and the rewinding process, and its winding efficiency is much higher than that of the prior art.

[0043] In another embodiment of the present application, please refer to Figures 1 to 8 as well. The winding cylinders 204 are arranged on the opposite sides of the winding shaft 201 along the radial direction of the winding shaft 201. The winding assembly further includes a linkage seat 206 connected to the power ends of the two winding cylinders 204. A clamping groove 207 corresponding to the bearing 203 is formed on the linkage seat 206, and the linkage seat 206 is connected to the outer ring of the bearing 203 through the clamping groove 207. According to the above structure provided in this embodiment, the connection of the linkage seat 206 connecting the two winding cylinders 204 to the outer ring of the bearing 203 through the clamping groove 207 can effectively improve the stability of the winding rod 202 moving along the axial direction of the winding shaft 201, which is beneficial to further improving the winding efficiency of the single-station automatic winding device of the bag-making machine in this embodiment.

[0044] In another embodiment of the present application, please refer to Figures 1 to 8 as well. The rotating sleeve 302 is key-connected to the winding shaft 201 and the winding shaft 201 can move relative to the rotating sleeve 302 along the axial direction of the rotating sleeve 302. The winding assembly further includes a sheath 208 connected to the rotating sleeve 302. The sheath 208 forms a receiving cavity for receiving the winding shaft 201, and the winding rod 202 can be received in the receiving cavity during the process of moving with the winding shaft 201. According to the above structure provided in this embodiment, the receiving cavity formed by the sheath 208 can protect the winding shaft 201 and the winding rod 202, which can effectively extend the service life of the single-station automatic winding device of the bag-making machine in this embodiment and make it have better winding efficiency. At the same time, when the winding rod 202 retracts into the sheath 208, the outer end face of the sheath 208 forms a block for the end face of the material roll, thereby completing the automatic unwinding of the material roll.

[0045] In another embodiment of the present application, please refer to Figures 1 to 8, two wall panels 100 are arranged at intervals; one group of winding components is arranged on each corresponding wall panel 100, and the coiling rods 202 in the two groups of winding components are coaxial and the opening ends of the forks 205 are facing each other. The winding drive mechanism also includes a transmission shaft 304 rotatably mounted on the wall panel 100, and the transmission shaft 304 is provided with synchronous pulleys 303 corresponding to the two groups of rotating sleeves 302, and the winding motor 301 is respectively connected to the two groups of winding components through the transmission shaft 304. According to the above structure provided in this embodiment, the winding motor 301 can drive the two groups of winding components to perform winding operations through the transmission shaft 304, which can not only significantly improve the winding stability of the single-station automatic winding device of the bag making machine in this embodiment, but also further improve its winding efficiency.

[0046] In another embodiment of the present application, please refer to Figure 1 , Figure 2 and Figure 5 The single-station automatic winding device of the bag-making machine also includes a stopper assembly and a top plate 401 connected between the wall panels 100. The stopper assembly includes a guide roller 402 that is arranged parallel to the winding shaft 201 and can rotate around its own central axis, and also includes a stopper cylinder 403 installed on the top plate 401 and a stopper plate 404 that is connected to the output end of the stopper cylinder 403 and can be driven by the stopper cylinder 403 to approach or move away from the guide roller 402. According to the above structure provided in this embodiment, the stopper plate 404 can approach or move away from the guide roller 402 under the driving action of the stopper cylinder 403. When the one-piece bag 1000 passes through the guide roller 402 during the winding process, the stopper plate 404 can cooperate with the guide roller 402 to clamp the one-piece bag 1000 or allow the one-piece bag 1000 to pass smoothly. In this way, the winding shaft 201 can continue to rotate and make the one-piece bag 1000 break at a predetermined point break position when the stop plate 404 and the guide roller 402 clamp the one-piece bag 1000, thereby completing the winding of a material roll. At the same time, when the stop plate 404 and the guide roller 402 clamp the one-piece bag 1000, the material head of the one-piece bag 1000 can be prevented from retreating and disengaging after the one-piece bag 1000 is broken, so as to ensure the normal subsequent automatic winding, thereby effectively avoiding manual operation and further improving the winding efficiency of the single-station automatic winding device of the bag making machine in this embodiment.

[0047] In another embodiment of the present application, please refer to Figure 1 , Figure 2 and Figure 6The single-station automatic winding device of the bag making machine also includes a floating roller 501 parallel to the winding shaft 201, a floating cylinder 502 installed on one of the wall panels 100, and a first swing arm 503, a swing shaft 504 and a bracket 505 which are sequentially connected between the output end of the floating cylinder 502 and the floating roller 501. The floating roller 501 is driven by the floating cylinder 502 to swing back and forth relative to the winding shaft 201 and can guide at least part of the bag body of the one-piece bag to the inner area of ​​the fork 205 during the swinging process relative to the winding shaft 201.

[0048] According to the above structure provided in the present embodiment, the floating roller 501 parallel to the winding shaft 201 can swing relative to the winding shaft 201 under the driving action of the floating cylinder 502 and drive at least part of the bag body of the target one-piece bag 1000 passing through the floating roller 501 to the inner area of ​​the fork 205. After at least part of the bag body of the one-piece bag 1000 is guided to the inner area of ​​the fork 205, the winding rod 202 moves forward to allow the target one-piece bag 1000 to enter the fork 205, so that the winding motor 301 can be restarted to quickly perform the winding operation. Since the winding motor 301 and the floating cylinder 502 in the present embodiment can both be connected to the automatic control system and operate automatically, the floating roller 501 that can swing can be provided in the present embodiment so that the single-station automatic winding device of the bag making machine provided in the present embodiment can automatically complete the continuous rewinding operation of the subsequent material roll and achieve a higher winding efficiency. It should be noted that please refer to Figure 6 and Figure 7 When the target one-piece bag 1000 is reloaded, that is, the bag enters the fork and the winding motor 301 rotates to rotate the winding rod 202, the stop plate 404 needs to be away from the guide roller 402 so that the target one-piece bag 1000 can be smoothly wound, synchronously, focus on Figure 6 and Figure 7 When the stop plate 404 moves away from the guide roller 402, the guide roller 402 rotates clockwise with the wheel disc 601, enters from under the one-piece bag 1000 between the floating roller 501 and the winding rod 202, and guides the one-piece bag 1000 onto the guide roller 402, and then the guide roller 402 continues to move with the wheel disc 601 to the initial position, that is, the position directly below the stop plate 404.

[0049] In another embodiment of the present application, please refer to Figure 1 , Figure 2 and Figure 6 The single-station automatic winding device of the bag making machine also includes a wheel 601 coaxially arranged with the rotating sleeve 302 and capable of rotating around the rotating sleeve 302, and a wheel driving mechanism that is transmission-connected to the wheel 601 and is used to drive the wheel 601. The guide roller 402 is rotatably installed on the wheel 601 and moves away from the rotating sleeve 302 in the radial direction of the wheel 601.

[0050] According to the above structure provided in this embodiment, please refer to Figure 7 and Figure 8 , the guide roller 402 installed on the turntable 601 can rotate around the central axis of the winding shaft 201 following the turntable 601. In this way, the guide roller 402 can re-pass through the conveying path of the target connected bag 1000 and support the target connected bag 1000 on the guide roller 402 during the rotation following the turntable 601. When the guide roller 402 rotates one week following the turntable 601 and returns to the initial position, the turntable 601 stops rotating to keep the guide roller 402 in the current position for guiding the connected bag 1000 during winding. When one roll is wound up, the stop plate 404 connected to the stop cylinder 403 can also cooperate with the guide roller 402 under the drive of the stop cylinder 403 to clamp the target connected bag 1000 and cooperate with the winding rod 202 to break the bag body of the connected bag 1000 at the dotted line. Thus, in this embodiment, through the cooperation of the floating roller 501, the guide roller 402 and the stop plate 404, the bag body breaking action is completed and the feeding action can be repeated. That is, the guide roller 402 that can rotate around the winding shaft 201 can cooperate with the stop plate 404 to repeatedly clamp the target connected bag 1000, and the winding rod 202 that can reciprocate under the drive of the winding cylinder 204 can repeatedly complete the unloading process. This enables the single-station automatic winding device of the bag making machine provided in this embodiment to have a winding efficiency much higher than that of the prior art.

[0051] In another embodiment of the present application, please refer to Figures 1 to 8 , the turntable drive mechanism includes a reduction motor 602 installed on one of the wall panels 100 and a pinion 603 connected to the power end of the reduction motor 602. A number of teeth for forming a gear transmission pair with the pinion 603 are provided on the edge of the turntable 601. According to the above structure provided in this embodiment, the turntable 601 can be driven by the pinion 603 connected to the reduction motor 602 to achieve a more stable rotation effect. In this way, through the coordinated cooperation of the floating roller 501, the stop plate 404 and the guide roller 402, the winding work of the subsequent material roll can be automatically completed, which is beneficial to further improving the winding efficiency of the single-station automatic winding device of the bag making machine in this embodiment.

[0052] In another embodiment of the present application, please refer to Figures 1 to 8, the roulette drive mechanism further includes a rotating shaft 604 connected to the power end of the reduction motor 602. The pinion gear 603 is mounted on the rotating shaft 604 and connected to the reduction motor 602 through the rotating shaft 604. The pinion gear 603 is arranged corresponding to the roulette 601 and is drivingly connected to the same rotating shaft 604. According to the above structure provided in this embodiment, the pinion gear 603 connected to the same rotating shaft 604 can drive two groups of roulettes 601 to achieve the technical effect of synchronous rotation, which is beneficial to further improving the winding efficiency of the single-station automatic winding device of the bag-making machine in this embodiment.

[0053] In another embodiment of the present application, please refer to Figures 4 to 8 , the single-station automatic winding device of the bag-making machine further includes a pressing plate 701 parallel to the winding shaft 201, a pressing plate cylinder 702 mounted on one of the wall plates 100, and a second swing arm 703 and a pressing plate rotating shaft 704 that are sequentially drivingly connected between the output end of the pressing plate cylinder 702 and the pressing plate 701. The pressing plate 701 is driven by the pressing plate cylinder 702 to swing reciprocally relative to the winding shaft 201 and can approach or move away from the winding shaft 201 during the process of swinging relative to the winding shaft 201. According to the above structure provided in this embodiment, the pressing plate 701 can not only abut against the connected bag 1000 during the winding process of the winding rod 202 on the target connected bag 1000, so that the single-station automatic winding device of the bag-making machine in this embodiment has better winding quality; but also can move away from the winding shaft 201 under the driving action of the pressing plate cylinder 702 to avoid the guide roller 402 rotating with the roulette 601, so that the single-station automatic winding device provided in this embodiment has higher winding efficiency.

[0054] The above are only the preferred embodiments of the present application and are not intended to limit the present application.
