[0030] A pushing member 10 is fixed to the right side of the guide block 4, and a top block 11 is fixed to the movable end of the pushing member 10. In this embodiment, the top block 11 is composed of a connecting plate directly fixedly connected to the movable end of the pushing member 10 and an extension block fixed to the front end of the connecting plate. There are two groups of extension blocks, which are arranged at the upper and lower ends of the connecting plate, and the end of the extension block away from the connection with the connecting plate passes through the guide block 4 and is located in the notch 3. The shortest distance between the two groups of extension blocks is between the inner diameter and the outer diameter of the winding drum 8. The purpose is to enable the front end of the extension block to contact the side wall of the winding drum 8. A slide groove 14 is opened on the side wall of the winding drum 8 along its radial direction. A ball 15 slidably connected to the slide groove 14 is embedded at the front end of the extension block. When the winding drum 8 is driven by the rotating shaft 32, the ball 15 slides between the slide groove 14 to avoid direct contact between the extension block and the outer wall of the winding drum 8, thereby reducing a certain friction force.

[0031] A guide strip 6 is fixed on the outer wall of the rotating shaft 32 along its length direction, and a guide groove 13 that can be slidably connected to the guide strip 6 is opened on the inner wall of the winding drum 8 along its length direction. A through hole 23 is opened in the middle of the rotating shaft 32. In this embodiment, a placement groove 24 is opened at the front and rear ends of the rotating shaft 32 respectively, and a baffle 22 is rotatably connected to the placement groove 24 through a rotating rod 30. A torsion spring 29 is fixed on one end of the rotating rod 30 and is rotatably connected to the inner wall of the placement groove 24. One end of the baffle 22 is located in the through hole 23. Inside the through hole 23, as shown in FIG. Figure 5 As shown, a driving rod 1 27 is provided at the right end of the rotating shaft 32, and a driving rod 20 is provided at the left end of the rotating shaft 32, and a guide groove 25 is respectively opened on the outer wall of the driving rod 1 27 and the driving rod 20 along its own length direction, and a sliding rod 26 slidably connected to the guide groove 25 is vertically fixed on the inner wall of the through hole 23, and a rack 28 is respectively provided at one end close to the driving rod 1 27 and the driving rod 20, which are arranged opposite to each other, and a gear 16 for meshing transmission is provided between the two sets of racks 28. In this embodiment, a rotating rod (not shown in the drawings) is fixed at the center of the gear 16 and is rotatably connected to the inner wall of the through hole 23. A disc (not shown in the drawings) is fixed to each other at one end of the driving rod 1 27 and the driving rod 20 that are away from each other. The purpose is that the disc is used to contact one end of the baffle 22 located inside the through hole 23. A telescopic spring 19 is fixed to the end of the driving rod 20 away from the driving rod 1 27 and is connected to the outer wall of the chassis 1. A magnetic block 21 is fixed to the end of the driving rod 1 27 away from the driving rod 2 20. A pushing member 2 12 is fixed to the outer wall of the guide block 4. The movable end of the pushing member 2 12 passes through the guide block 4 and is located in the notch 3. An electromagnetic suction block 31 that magnetically cooperates with the magnetic block 21 is fixed to the front side of the movable end of the pushing member 2 12.

[0032] A stand 17 is vertically fixed on the upper side of the base 5, and a U-shaped support block 18 is fixed on the stand 17. A sliding groove 9 slidably connected to the support block 18 is provided along the length direction of the guide block 4 on the side away from the rotating shaft 32. The purpose is that when the guide block 4 moves horizontally away from the chassis 1 driven by the slider 33, the support block 18 can provide a certain support to the guide block 4.

[0033] In this embodiment, the pushing member 10 and the pushing member 2 12 are both piston cylinders.

[0034] When winding polyester film, Figure 1As shown, the winding drum 8 is sleeved on the outer wall of the rotating shaft 32, and the guide groove 13 of the winding drum 8 and the guide strip 6 of the rotating shaft 32 are in a sliding connection state, the pushing member 10 is in a retracted state, and the front end of the top block 11 touches the slide groove 14 on the outer wall of the winding drum 8 through the ball 15, the driving rod 1 27 and the driving rod 20 are in a state of being away from each other, the telescopic spring 19 is in a compressed state, the electromagnetic suction block 31 on the pushing member 2 12 and the magnetic suction block 21 on the driving rod 1 27 are in a magnetically matched state, the pushing member 2 12 is in a retracted state, the front end of the baffle 22 is in a state of being rotated out of the placement groove 24 and fitting with the outer wall of the winding drum 8 on the outer wall of the rotating shaft 32, and the torsion spring 29 is in a force-twisted state.

[0035] When the winding drum 8 finishes winding the polyester film, the control system controls the rotating shaft 32 to stop rotating, and then the electromagnetic suction block 31 begins to lose power and no longer cooperates with the magnetic suction block 21, the telescopic spring 19 begins to reset, pulling the driving rod 20 to move horizontally away from the chassis 1, and at the same time, the rack 28 on it meshes with the gear 16 for transmission, and the gear 16 drives the rack 28 on the driving rod 1 27, so that the driving rod 1 27 and the driving rod 20 begin to approach each other, and at the same time, the disks on one end of the driving rod 1 27 and the driving rod 20 no longer conflict with the baffle 22, and the torsion spring 29 begins to reset, and drives the front end of the baffle 22 to rotate back into the placement groove 24 through the rotating rod 30, and no longer blocks the outer wall of the winding drum 8 on the outer wall of the rotating shaft 32.

[0036] Then the motor 2 starts to rotate forward, driving the ball screw 7, and the slider 33 on the ball screw 7 drives the guide block 4 to move horizontally away from the chassis 1, and the winding drum 8 in the guide block 4 is synchronously driven horizontally away from the rotating shaft 32. Figures 2 to 4 As shown, after the winding drum 8 completely leaves the rotating shaft 32, personnel can place a transport vehicle for storing the winding drum 8 on the right side of the base 5. After placement, the control system controls the pushing member 10 to start extending, and the ball 15 on the top block 11 moves out of the slide groove 14 on the winding drum 8. The winding drum 8 is no longer supported and falls due to gravity.

[0037] After taking down the winding drum 8 with the polyester film wound on it, the personnel put the empty winding drum 8 into the notch 3 of the guide block 4, and then the pushing member 10 starts to reset, so that the ball 15 on the top block 11 re-enters the slide groove 14 on the winding drum 8, playing a role in supporting the winding drum 8 in the notch 3, and then the motor 2 starts to reverse and start, the ball screw 7 drives the slider 33 to move horizontally in the direction of the chassis 1, and the guide block 4 is driven synchronously, and the winding drum 8 inside it starts to move and starts to be sleeved on the outer wall of the rotating shaft 32. After the sleeve is completed, the motor 2 stops, and the winding drum 8 is now located between the placement grooves 24 at the left and right ends of the rotating shaft 32, and then the control system controls the pushing member 2 12 to extend, so that the electromagnetic suction block 31 at the front end of the pushing member 2 12 is opposite to the magnetic suction block 21 of the driving rod 1 27 in the rotating shaft 32, and then the electromagnetic suction block 31 starts to be energized and the magnetic suction block 21 is received. The magnetic block 21 cooperates with the magnetic attraction, and the pushing member 2 12 begins to reset and retract, driving rod 1 27 is indirectly driven to move away from the chassis 1. At the same time, the rack 28 on the driving rod 1 27 is meshed with the gear 16 for transmission, and the driving rod 20 is indirectly driven, and the driving rod 1 27 and the driving rod 2 20 move away from each other. It should be noted that due to the sliding rod 26 in the through hole 23, the driving rod 1 27 and the driving rod 20 both move horizontally in the through hole 23, and the telescopic spring 19 begins to be compressed. The disks on the driving rod 1 27 and the driving rod 20 respectively contact the baffles 22 at the placement grooves 24 at the left and right ends of the rotating shaft 32, and drive them to rotate around the central axis of the rotating rod 30, so that the front end of the baffle 22 moves out of the placement groove 24 and fits onto the outer wall of the winding drum 8, limiting the left and right positions of the winding drum 8 to prevent excessive left and right deviation when it rotates.

[0038] The above embodiments are intended to illustrate the present invention, not to limit the present invention. Any solution that is a simple transformation of the present invention falls within the protection scope of the present invention.
