Description

Technical Field

[0001] This utility model relates to the technical field of plastic film winding and feeding equipment, specifically to a fully automatic continuous feeding device for plastic film winding. Background Technology

[0002] After the plastic film is produced and wound onto the unwinding roller, it will be rewound and cut by a rewinding and slitting machine according to different specifications. At present, after the plastic film on the unwinding roller is wound up, the rewinding and slitting machine needs to stop winding, remove the old unwinding roller and replace it with a new one before it can continue winding. In the process of feeding plastic film, the unwinding roller is usually disassembled and installed manually after the rewinding machine is stopped. The new unwinding roller, which is wrapped with plastic film, is heavy and manual handling is time-consuming and laborious. Moreover, the manual installation and disassembly method also increases the feeding time. Utility Model Content

[0029] like Figure 1 and Figure 3 As shown, this utility model provides a fully automatic continuous feeding device for plastic film rewinding, including a plastic film rewinding equipment 1, a feeding conveyor 2 at the bottom of the plastic film rewinding equipment 1, and a film unwinding roller lifting assembly 3 on the top surface of the feeding conveyor 2.

[0030] like Figure 2 As shown, the plastic film rewinding equipment 1 specifically includes a bottom support 11, a take-up roller rotating component 12 fixed to the left front side of the upper surface of the bottom support 11, and a film removal roller driving component 17 fixed to the left rear side of the upper surface of the bottom support 11. A take-up roller 13 is connected to the output end of the take-up roller rotating component 12, and a film removal roller 37 is connected to the output end of the film removal roller driving component 17. A slitting roller 14 is rotatably arranged at the middle front side of the top surface of the bottom support 11, and a pressing roller 15 is rotatably arranged at the middle rear side of the top surface of the bottom support 11.

[0031] like Figure 4As shown, the film removal roller lifting assembly 3 specifically includes two Y-shaped support frames 31 fixed to the surface of the conveyor belt of the feeding conveyor 2, and servo electric push rods 32 installed on the opposite sides of the Y-shaped support frames 31. A movable bracket 33 is fixedly connected to the telescopic shaft of the servo electric push rod 32. The film removal roller 37 to be replaced is placed on the upper surface of the movable bracket 33 and the Y-shaped support frame 31. Multiple layers of plastic film 38 are wound on the outer surface of the film removal roller 37. Quadrangular prisms 35 are inserted into the left and right ends of the film removal roller 37. Iron rollers 34 are fixed to the ends of the quadrangular prisms 35 away from the film removal roller 37. The top arc surface of the movable bracket 33 is provided with positioning protrusions, and the side of the protrusions that are close to each other contacts the left and right end faces of the film removal roller 37.

[0032] Specifically, two bearing seats are fixedly connected to the front side of the top surface of the bottom support 11. The two ends of the take-up roller 13 are inserted into the bearing seats for rotation. The left end of the take-up roller 13 is connected to the driven gear. A servo motor is installed on the inner surface of the bottom support 11. The output shaft of the servo motor is connected to the drive gear through a coupling. The driven gear and the drive gear mesh with each other. Two support seats are fixedly connected to the front side of the middle of the top surface of the bottom support 11. The two ends of the slitting roller 14 are inserted into the support seats for rotation. Several cutting blades are evenly arranged on the outer ring of the slitting roller 14.

[0033] Meanwhile, a bearing seat is fixedly connected to the rear middle position of the top surface of the bottom support 11, and the two ends of the pressure roller 15 are inserted into the bearing seat for rotation. Two bearing seats are fixedly connected to the rear position of the top surface of the bottom support 11, and a rotating shaft is rotatably connected inside each bearing seat. An electromagnet 16 is fixedly connected to one end of the rotating shaft that is close to the other. The iron roller 34 is connected to the electromagnet 16 by magnetic attraction. The left end of the rotating shaft on the left side is fixed with a first gear, and a drive motor is fixed to the left side of the top surface of the bottom support 11. A second gear that meshes with the first gear is fixed to the output shaft of the drive motor through a coupling.

[0034] More specifically, a rectangular through hole is provided on the top rear side of the bottom bracket 11 for the unwinding roller 37 to pass through when it moves up and down, and photoelectric position sensors are installed on the left and right side frames of the feeding conveyor 2.

[0035] One end of the plastic film 38 is wound onto the outer surface of the unwinding roller 37, and the other end is wound onto the outer surface of the take-up roller 13. The plastic film 38 passes through the slitting roller 14 and the pressing roller 15, and the plastic film 38 contacts the top surface of the outer ring of the slitting roller 14 and the bottom surface of the outer ring of the pressing roller 15. Both ends of the unwinding roller 37 have square grooves 36 for coupling with the quadrangular prism 35 for insertion. The top surfaces of the movable bracket 33 and the Y-shaped support frame 31 are both provided with arcs that couple with the shaft of the unwinding roller 37.

[0036] Based on the above-described preferred technical solution, the workflow of this technical solution is explained as follows:

[0037] After the plastic film 38 on the outer ring of the unwinding roller 37 is wound up, it reaches the old unwinding roller 37 via the Y-shaped support frame 31 and the movable bracket 33 on the feeding conveyor 2. The movable bracket 33 is raised by the servo electric push rod 32. After the power supply to the electromagnet 16 is turned off, the old unwinding roller 37 falls onto the movable bracket 33. At this time, the old unwinding roller 37 is transported back by the feeding conveyor 2. Then, the new unwinding roller 37, fully rolled with plastic film 38, is placed on the movable bracket 33 and the Y-shaped support frame 31. After the feeding conveyor 2, in conjunction with the photoelectric position sensor, transports the unwinding roller 37 to below the old unwinding roller 37, the movable bracket 33 is lifted using the servo electric push rod 32. With the maximum lifting height of the servo electric push rod 32 set to be level with the electromagnet 16, the new unwinding roller 37 will be level with the electromagnet 16. At the same time, the electromagnet 16 is energized to generate magnetic attraction to the iron roller 34, thereby allowing a portion of the quadrangular prism 35 to be pulled out from the square groove 36. After the unwinding roller 37 is connected, the worker sequentially winds the end of the plastic film 38 onto the pressing roller 15, the slitting roller 14, and the take-up roller 13 for the next stage of winding and slitting operations.

[0038] It should be stated that the above-described specific embodiments are merely preferred embodiments of this utility model and the technical principles employed. Those skilled in the art should understand that various modifications, equivalent substitutions, and variations can be made to this utility model. However, such variations, as long as they do not depart from the spirit of this utility model, should be within the protection scope of this utility model. Furthermore, some terminology used in this application specification and claims is not limiting, but merely for ease of description.
