DETAILED DESCRIPTION

[0022] To make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the embodiments of the utility model are described in detail below with reference to the drawings, but the embodiments described in the utility model are part of the embodiments of the utility model, rather than all the embodiments.

[0023] The embodiment of the present application provides a pre-coating film roll mounting structure, which comprises a machine body 1, a mounting shaft 2, a top supporting mechanism 3 and a movable rod 4. Figures 1-5 As shown in the figure, the pre-coating film roll mounting structure comprises a machine body 1, a mounting shaft 2, a top supporting mechanism 3 and a movable rod 4.

[0024] The machine body 1 is provided with a first mounting seat 11 and a second mounting seat 12, one end of the mounting shaft 2 is hingedly connected to the first mounting seat 11, the other end of the mounting shaft 2 is detachably arranged on the second mounting seat 12, and a mounting hole 21 is coaxially arranged on the other end of the mounting shaft 2. Correspondingly, a conveying roller, a guide shaft, a sensor and a rotating shaft for mounting a label roll without a coating film are arranged between the first mounting seat 11 and the second mounting seat 12. The top supporting mechanism 3 comprises at least two guide seats 31 which are arranged in a circumferential array around the axis of the mounting shaft 2. A guide hole 35 which penetrates through the mounting hole 21 is arranged on the guide seat 31. The axis of the guide hole 35 is arranged perpendicularly intersecting the axis of the mounting shaft 2. A top supporting rod 32 is movably arranged in the guide hole 35. One end of the top supporting rod 32 is located outside the mounting shaft 2 and is provided with a roller 33. The rotating axis of the roller 33 is arranged parallel to the mounting shaft 2. The roller 33 is used for supporting and rolling with the inner wall of the pre-coating film roll. The other end of the top supporting rod 32 is located in the mounting hole 21 and is provided with a matching block 34. The movable rod 4 is coaxially arranged in the mounting hole 21 and is movably arranged along its axis. The movable rod 4 is provided with a top block 41 which matches the matching block 34. The top block 41 is used for moving the top supporting rod 32 along the axis of the guide hole 35 to the outside of the mounting shaft 2 along with the movement of the movable rod 4.

[0025] In application, the mounting shaft 2 is taken off from the second mounting seat 12 and is rotated by a predetermined angle, so that the mounting shaft 2 is inserted into the center hole of the pre-coating film roll. Then the other end of the mounting shaft 2 is arranged on the second mounting seat 12 again and the movable rod 4 is moved, so that the top block 41 on the movable rod 4 contacts with the matching block 34 on one end of the top supporting rod 32. The top supporting rod 32 moves along the axis of the guide hole 35 to the outside of the mounting shaft 2 under the cooperation of the matching block 34 and the top block 41. The roller 33 arranged on the other end of the top supporting rod 32 gradually approaches the inner wall of the pre-coating film roll. When the rollers 33 on the top supporting rods 32 are all supported on the inner wall of the pre-coating film roll, the center axis of the pre-coating film roll coincides with the axis of the mounting shaft 2. At the same time, the roller 33 makes the pre-coating film roll rotate around its axis, so that the installation of the pre-coating film roll is completed. Then the label to be coated and the pre-coating film are pulled out and are unwound through the guide wheel, the conveying roller and the like, so that the coating operation is started. Through the arrangement of the matching block 34 and the top block 41 and under the cooperation of the movable rod 4 and the top supporting rod 32, when the pre-coating film roll is installed, the pre-coating film roll only needs to be inserted into the mounting shaft and the movable rod 4 is moved, so that the roller 33 on the top supporting rod 32 is supported on the inner wall of the pre-coating film roll. The installation process of the pre-coating film roll is greatly simplified, which is beneficial to improve the label coating efficiency and the printing efficiency.

[0026] Specifically, as shown in the figure, Figures 1-4As shown, the top support mechanism 3 has two groups and is arranged along the axis of the mounting shaft 2, the distance between the two groups of top support mechanisms 3 is adapted to the length of the pre-coated film roll, that is, the rollers 33 in the two groups of top support mechanisms 3 can respectively support the inner wall of the two ends of the pre-coated film roll, each group of top support mechanisms 3 has four guide seats 31 and is arranged in a circular array around the axis of the mounting shaft 2, and each guide hole 35 movably fits with a top support rod 32, that is, each group of top support mechanisms 3 uses four rollers 33 to support the inner wall of the pre-coated film roll, so that the pre-coated film roll has high installation stability, and the stress on the inner wall of the pre-coated film roll is uniform, which can effectively reduce the amount of jumping of the pre-coated film roll during rotation, avoid problems such as bubbles and edge lifting of the film, and ensure the quality of the label printing product.

[0027] Specifically, as shown in Figure 4 and Figure 5 The bottom of the matching block 34 is provided in a convex circle, the top block 41 is semispherical, the central axis thereof coincides with the movable rod 4, the spherical surface of the top block 41 is arranged towards the bottom of the mounting hole 21, and a support seat 213 can be arranged at the lower end of the mounting hole 21, the other end of the movable rod 4 passes through the support seat 213 and is provided with a limiting block 42, when the limiting block 42 abuts against the support seat 213, the top block 41 and the matching block 34 are in a separated state. Since the movable rod 4 is long, the support seat 213 can provide support for the movable rod 4 during movement of the movable rod 4, thereby ensuring the strength of the movable rod 4 and effectively avoiding the problem of deformation of the movable rod 4 after long-term use; the semispherical top block 41 cooperates with the convex circle of the bottom surface of the matching block 34, so that the top support rod 32 moves while effectively reducing the resistance of the movable rod 4, reducing the wear of the top block 41 and the matching block 34, and improving the service life.

[0028] Since the pre-coated film roll needs to be inserted from the other end of the mounting shaft 2, and the movable rod 4 needs to be driven at the other end of the mounting shaft 2, if a linear mechanism such as a pneumatic cylinder, an electric cylinder or a rack is arranged at the other end of the mounting shaft 2 to drive the movable rod 4, it may affect the installation of the pre-coated film roll. The present embodiment provides a preferred solution, which is as follows: a movable column 211 is threadedly fitted at the upper end of the mounting hole 21, one end of the movable column 211 is connected with a rotating rod 212 coaxially arranged with the movable rod 4, and one end of the movable rod 4 is rotatably fitted at the other end of the movable column 211. The rod diameter of the rotating rod 212 is smaller than the shaft diameter of the mounting shaft 2, so it will not affect the insertion of the pre-coated film roll; rotating the rotating rod 212 to drive the movable column 211 to rotate, thereby achieving the movement of the movable rod 4, and at the same time, the self-locking property of the threaded fitting can effectively fix the movable rod 4, thereby improving the stability of the rollers 33 in supporting the inner wall of the pre-coated film roll and further reducing the amount of jumping of the pre-coated film roll during rotation.

[0029] Specifically, as shown in Figures 1-3As shown, the second mounting seat 12 is provided with a clamping groove 121 matched with the shaft diameter of the mounting shaft 2, and a rubber pad is attached in the clamping groove 121 for clamping the mounting shaft 2. Through the interference fit between the rubber pad and the mounting shaft 2, the mounting shaft 2 can be effectively fixed, and meanwhile, the mounting shaft 2 is convenient to disassemble.

[0030] The above only describes the preferred embodiments of the present application and is not used to limit the present application. Obviously, those skilled in the art can make various modifications and variations to the present application without departing from the spirit and scope of the present application.
