This entire process requires manual unloading, which is labor-intensive and inefficient. Consequently, some assisted unloading mechanisms have emerged on the market, but their overall structures are generally complex, with a low degree of automation, and still require manual assistance.

[0018] As shown in the figure, the utility model discloses an automatic unloading mechanism of a film blowing machine, including a lifting seat 12, the lifting seat 12 is connected to the lifting drive assembly, the lifting seat 12 is provided with a first clamping jaw 8 and a second clamping jaw 10 arranged in cooperation, and an exhaust head assembly cooperating with the inflatable shaft 5, the first and second clamping jaws are connected to the clamping drive assembly, the first and second clamping jaws can clamp the inflatable shaft 5 to restrict the inflatable shaft from moving axially, and a horizontal support assembly is also provided corresponding to the inflatable shaft 5, a placement rack 2 is provided on one side of the lifting seat 12, and the placement rack 2 is connected to the movable drive assembly. Specifically, the movable drive assembly includes a first movable frame 3 and a second movable frame 4, the placement rack 2 is arranged on the first movable frame 3, and the first movable frame 3 is movably arranged on the second movable frame 4, and the first and second movable frames are connected to the corresponding movable drive assembly, thereby realizing the placement rack 2 to move forward and backward, left and right in the horizontal direction, and the movable drive assembly can be a common linear drive structure such as a linear motor, a gear rack structure, a synchronous belt structure, and a screw structure.

[0019] Furthermore, the lifting drive assembly includes a first motor 17 mounted on the lifting base 12. The output end of the first motor 17 is connected to a gear 16, which meshes with a fixed rack 15. A slide 14 is mounted on the lifting base 12, and a slide rail 13 is mounted on the frame, which engages with the slide 14. With this structure, the lifting base 12 can be raised and lowered by controlling the first motor 17 to rotate the gear 16 and engage the rack 15, thereby guiding the slide rail 13.

[0020] Furthermore, the clamping drive assembly is a clamping cylinder 11, and the first clamping jaw 8 and the second clamping jaw 10 are connected to the clamping cylinder 11. By controlling the action of the clamping jaw cylinder 11, the first and second clamping jaws can be controlled to clamp or release the inflatable shaft.

[0021] Furthermore, a bearing 9 is provided on the inflatable shaft 5 for axial limiting. The limiting method can be achieved by limiting the two ends of the bearing 9 by using a positioning step and an interference fit limit sleeve on the inflatable shaft. After the first and second jaws clamp the inflatable shaft 5, they can be against the side of the bearing 9. With this structure, the limiting of the bearing 9 and the jaws is increased to ensure that the inflatable shaft 5 does not move axially.

[0022] Furthermore, the horizontal support assembly includes an extension portion 7 integrally provided on the lifting seat 12, and a support seat 6 is provided on the extension portion 7, which can support the inflatable shaft 5. With this structure, the inflatable shaft can be naturally supported when it is delivered to the clamping assembly.

[0023] Furthermore, the horizontal support assembly includes a support platform 25, which is connected to a scissor-fork connecting rod structure. The scissor-fork connecting rod structure is a relatively common multi-link transmission structure, which is mainly composed of a connecting rod group that is cross-hinged together from top to bottom. The bottom drive connecting rod 22 is slidably set on the base and screwed to the drive screw 24. The drive screw is connected to the output end of the drive motor 21. The top drive connecting rod 27 is slidably set in the slide groove 26 on the support platform 25. By controlling the drive motor 21 to drive the drive screw 24 to rotate, the drive connecting rod 22 can be driven to move, and then the transmission connecting rod group drives the connecting rod group to retract downward or open upward to realize the lifting and lowering of the support platform 25. When the film roll 1 and the inflatable shaft 5 are separated, the support platform 25 descends to make way. When the two are separated, the support platform 25 rises to support the inflatable shaft 5, and then descends together with the lifting seat 12 to transfer the inflatable shaft 5 to the empty placement rack 2 that is subsequently moved to the location for the transfer of the inflatable shaft 5. The scissors fork connecting rod structure is arranged on the movable seat 28, and the movable seat 28 is connected to the horizontal drive component. The horizontal drive component can be a common linear drive structure such as a synchronous belt structure, a gear rack structure, a linear motor, a screw rod, a cylinder, etc. The movement of the movable seat 28 is adapted to the movement of the placement frame 2 to avoid interference with the movement of the placement frame 2. For example, when the placement frame 2 moves to the clamping claw, the movable seat 28 also moves to the right adaptively. When the placement frame 2 moves to the left away from the clamping claw, the movable seat 28 also moves to the left adaptively. At this time, the support platform 25 can rise to support the inflatable shaft 5.

[0024] Furthermore, the vacuum head assembly includes an air nozzle 20, to which a connecting pipe 19 is connected. The connecting pipe 19 is connected to the vacuum pump via an air pipe. One end of the air nozzle 20 is connected to a movable drive assembly. In this embodiment, the movable drive assembly is a first cylinder 18, and the piston rod of the first cylinder 18 is connected to the air nozzle 20. Of course, the movable drive assembly can also adopt other common linear drive structures such as gear racks, linear motors, and screw structures. With the above structure, by controlling the action of the first cylinder 18, the air nozzle 20 can be driven to move to the inflatable shaft 5, and then the inflatable shaft 5 is evacuated to ensure that the key strip of the inflatable shaft 5 can be retracted and separated from the film roll 1.

[0025] The working principle of the present invention is as follows: the wound film roll 1 and the inflatable shaft 5 are sent together from the winding assembly to the placement rack 2, and the placement rack 2 drives the film roll 1 and the inflatable shaft 5 to move together to the unloading station. At this time, the first and second clamping claws act to clamp the inflatable shaft 5 and position it. At the same time, the air nozzle 20 moves to the inflatable shaft 5 to pump air into the inflatable shaft 5, so that the key strip of the inflatable shaft 5 is retracted and separated from the film roll 1. At this time, the placement rack 2 will drive the film roll to move along the axial direction of the inflatable shaft, so that the film roll 1 and the inflatable shaft are separated. The shaft 5 is separated, and the separated inflatable shaft is still clamped by the first and second clamps and supported by the support seat 6. When the film roll 1 is removed from the placement rack 2, the placement rack 2 moves again to the bottom of the inflatable shaft 5. At this time, the lifting seat 12 drives the inflatable shaft 5 to descend until the inflatable shaft 5 is placed on the placement rack 2. Then the placement rack 2 moves to send the inflatable shaft 5 to the winding assembly. The swing arm structure in the winding assembly swings (which belongs to the common existing technology) to send the empty inflatable shaft back into the winding assembly for winding.

[0026] The structure of the present invention can realize the vacuuming and clamping positioning of the inflatable shaft, and by controlling the movement of the placement rack, realize the separation of the film roll and the inflatable shaft, and the transfer operation of the inflatable shaft and the film roll, realizing automatic unloading of the roll throughout the process, effectively reducing the labor intensity of workers and improving the efficiency and stability of unloading.
