Description

Technical Field

[0001] The utility model relates to the technical field of plastic processing equipment, in particular to a device for quickly replacing a degradable plastic film reel. Background Art

[0002] Degradable films have the functions and characteristics of traditional plastics, and after reaching the end of their service life, they can be broken down and degraded in the natural environment through the action of microorganisms in the soil and water or through the action of ultraviolet rays in the sun, and finally re-enter the ecological environment in a reduced form. Currently, the most common degradable plastic films are made of degradable materials such as polyhydroxyalkanoates, polylactic acid, carbon dioxide copolymers, and starch-based cellulose. After the degradable plastic film is processed or after the trimming operation is completed, it needs to be rolled up.

[0003] When the existing reel is in use, a motor is used to drive the reel to rotate so as to wind up the degradable plastic film. However, when replacing the reel, it is generally done manually. The weight of the reel itself plus the degradable plastic film wrapped on its surface increases the weight of the handling. When workers replace the reel, they need to pay attention to their own safety and the replacement efficiency is also reduced, which affects the overall manufacturing speed of the degradable plastic film. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides a degradable plastic film reel quick replacement device to solve the above problems.

[0006] The rotating member comprises a limit bar frame installed on one side of the strap, one end of the limit bar frame is provided with an opening, the lower end of the limit bar frame is provided with an outlet, a rotating shaft is movably installed inside the limit bar frame, and a slot is provided on the outer surface of the rotating shaft.

[0007] By adopting the above technical solution, the two ends of the reel component move inside the two sets of limit strip frames respectively. When the slots opened on the outer surface of the rotating shaft are aligned with the inside of the limit strip frames, the reel component moves into the slots to complete the replacement of the reel component.

[0008] Preferably, an axle seat is installed on the outer side of the strap, and a motor is installed on the outer side of the winding platform, and the output end of the motor passes through the axle seat and is connected to one end of the rotating shaft.

[0010] By adopting the above technical scheme, the motor drives the rotating shaft to rotate inside the limiting strip frame, and when the card slot is aligned with the inside of the limiting strip frame, the reel component can be moved into the card slot to complete the installation of the reel component, and the degradable plastic film is wrapped around the outer surface of the shaft body. After the shaft body has wrapped the degradable plastic film within its own range, the cylinder shrinks a certain distance and then stops shrinking, and the outlet is opened. After the limit block contacts the arc strip, the cylinder shrinks and drives the reel component wrapped with the degradable plastic film to move downward together. The reel component is restricted by the degradable plastic film roll and cannot continue to move downward. The cylinder extends and moves the upward arc strip back to the inside of the outlet. The set arc strip will close the outlet to facilitate the rotation of the reel component.

[0011] Preferably, the arc-shaped bar is aligned with the outlet position, the cylinder passes through one side of the V-shaped plate, and the top end of the limiting rod is installed on the bottom end of the shaft seat.

[0012] By adopting the above technical solution, when the cylinder drives the arc-shaped bar to move up and down, the provided limit rod will limit the moving arc-shaped bar.

[0013] Preferably, the reel component comprises an axle body and a limiting column installed on the outside of the axle body, a limiting block is provided on the outside of the limiting column, and a limiting hole is formed through the middle end of the limiting block.

[0014] Preferably, the limiting column is matched with the limiting hole, and the shape and size of the limiting block are consistent with the shape and size of the slot.

[0015] By adopting the above technical solution, the provided limiting column is inserted into the inside of the limiting hole, so that the limiting block can drive the shaft body to rotate through the matching limiting hole and the limiting column.

[0023] The utility model is further described below in conjunction with the accompanying drawings and implementation modes.

[0024] Embodiment 1

[0025] Reference Figure 1-Figure 4 A degradable plastic film reel quick replacement device shown in the figure comprises a reeling platform 1, the reeling platform 1 is provided with two groups, a stand 2 is installed on one side of the top of the two groups of reeling platforms 1, a rotating groove 11 is opened in the middle of the top surface of the reeling platform 1, a lifting groove 12 is opened on one side of the rotating groove 11, a strap 3 is installed on the top of the reeling platform 1, the strap 3 is installed on the upper end of the lifting groove 12, a rotating member 6 is installed on the outer side of the stand 2, a reel member 7 is installed inside the rotating member 6, a pad 4 is installed between the lower ends of the reeling platform 1, and a baffle 5 is installed on one side of the top of the pad 4;

[0026] The rotating member 6 includes a limit bar frame 65 installed on one side of the butt plate 3, an opening 66 is provided at one end of the limit bar frame 65, an outlet 67 is provided at the lower end of the limit bar frame 65, the limit bar frame 65 is arranged in an inclined shape, the position of the opening 66 is higher than the position of the outlet 67, and one end of the limit bar frame 65 is in an arc shape.

[0027] A rotating shaft 64 is movably installed inside the limiting frame 65, and a slot 63 is provided on the outer surface of the rotating shaft 64. A shaft seat 62 is installed on the outer side of the strap 3, and a motor 61 is installed on the outer side of the winding table 1. The output end of the motor 61 passes through the shaft seat 62 and is connected to one end of the rotating shaft 64. The motor 61 adopts a speed-regulating motor. When the winding shaft component 7 is removed and reinstalled, the speed of the motor 61 is relatively slow. The rotating shaft 64 is movably installed inside one end of the limiting frame 65 that is in a circular arc shape.

[0028] A V-shaped plate 13 is installed at the lower end of the inner part of the rotating groove 11, and one end of the V-shaped plate 13 is connected to the pad 4. A mounting seat 14 is installed between the bottom ends of the winding table 1, and a cylinder 15 is installed at the top of the mounting seat 14. An arc strip 17 is installed at the movable end of the cylinder 15. The cross-sectional shape of the arc strip 17 is consistent with the shape of the outlet 67. A limit rod 16 is installed through one end of the arc strip 17, and the bottom end of the limit rod 16 is installed on one side of the inner part of the V-shaped plate 13. The degradable plastic film is wrapped around the outer surface of the shaft body 71.

[0031] The limiting column 74 is adapted to the limiting hole 73, and the limiting block 72 is consistent with the shape and size of the card slot 63, so that the limiting block 72 is inserted into the card slot 63, the card slot 63 is aligned with the inner part of the limiting strip frame 65, and the limiting block 72 moves into the card slot 63. During the rotation of the reel member 7, after the card slot 63 is aligned with the outlet 67, the limiting block 72 moves out from the inside of the card slot 63, and the limiting block 72 moves down through the outlet 67, and the reel member 7 and the degradable plastic film wrapped therein move down together, and the limiting block 72 and the arc strip 17 are aligned. After contact, the cylinder 15 contracts, driving the reel component 7 wrapped with the degradable plastic film to move downward, the cylinder 15 extends, and the arc strip 17 is set to close the outlet 67 to facilitate the rotation of the reel component 7. The shaft body 71 and the limit column 74 and the limit block 72 are detachable, which is convenient for disassembly of the limit blocks 72 at both ends of the shaft body 71 after the film is rolled up, and can be used for other shaft bodies 71.
