Description

Technical Field

[0001] The utility model relates to the technical field of winding devices, in particular to a winding device for pre-coating film production. Background Art

[0002] Pre-coated film refers to the process of pre-gluing and rewinding the plastic film and then laminating it with paper printed products. The pre-coated film processing factory first applies glue on the film according to the specifications and format of use, rewinds it for the user to choose, and then laminates it with the printed product.

[0003] A Chinese patent application has been found to disclose a winding mechanism for pre-coated film (authorization announcement number: CN212503186U), which includes a frame with a winding roller rotatably connected therein, a drive motor for driving the winding roller to rotate connected to the outer wall of the frame, and a limit assembly provided on the winding roller. The limit assembly includes two limit rings sleeved on the winding roller, and the two limit rings are connected to a fixing member on the opposite sides of the two limit rings. The fixing member includes two fixing rods connected to the side walls of the limit rings. The two fixing rods are respectively located on both sides of the winding roller and are parallel to each other. The two ends of the fixing rods facing the limit rings are connected to dovetail blocks. The limit rings have four dovetail grooves on the side facing the fixing rods for the dovetail blocks to be respectively inserted and slid. Each dovetail groove is perpendicular to the length of the fixing rods, and a bidirectional screw is threaded between the two ends of the two fixing rods. The pre-coated film is wound between the two limit rings to prevent the pre-coated film from shifting during winding.

[0004] In actual application, this patented technology can limit the pre-coated film to prevent the pre-coated film from shifting during the winding process. However, during use, the winding roller needs to be replaced with a new one after the winding is completed. After the winding roller is wound, it is not convenient for the staff to remove the winding roller from the frame, which will cause great inconvenience to the staff and reduce work efficiency. At the same time, the width of the pre-coated film is diverse, and different lengths of winding shafts are required. The position of the bracket on the frame in the above solution is fixed, so the pre-coated film larger than the width of the frame cannot be wound, which greatly reduces the practicality of the device.

After the winding of the winding shaft 5 is completed, the second handle 83 is turned again to drive the second threaded rod 81 to rotate, and the pressure plate 82 is driven to move, so that the pressure plate 82 is pressed and fixed to the second bearing seat 10, and then one end of the pre-coated film is wound around the winding shaft 5. The motor 6 can be started to drive the winding shaft 5 to rotate through the clamping block 13 and the connecting block 14. When the winding shaft 5 is wound, the second threaded rod 81 is driven to rotate by turning the second handle 83 again, and the pressure plate 82 is driven to move, so that the pressure plate 82 and the second bearing seat 10 are separated, and the winding shaft 5 is slightly lifted, so that the second bearing seat 10 is disengaged from the clamping groove 9. Then, the first handle 74 is turned again to drive the first threaded rod 71 to rotate, so that the first support plate 2 and the second support plate 3 are moved, so that the distance between the first support plate 2 and the second support plate 3 is greater than the length of the winding shaft 5, and the winding shaft 5 can be taken out from the first support plate 2 and the second support plate 3.
