[0038] Please refer to Figure 1 As shown, the purpose of this embodiment is to provide a poly lactic acid coated paper cup forming unwinding device, which includes a mounting rod 1 and a paper roll 2 arranged thereon.

[0039] Furthermore, please refer to Figure 1 - Figure 2 As shown, it further includes a mounting seat assembly 7. A hydraulic rod 3 is arranged on the mounting seat assembly 7, and a clamping arm 4 is arranged on the hydraulic rod 3 for clamping the paper roll 2; the hydraulic rod 3 raises the new paper roll 2 to a specified height position through the clamping arm 4;

[0040] A transmission assembly 6 is arranged on the mounting seat assembly 7. Sliding assemblies 5 for supporting the mounting rod 1 are symmetrically arranged at both ends of the transmission assembly 6. The sliding assemblies 5 are slidably connected to the mounting seat assembly 7 and are driven by the transmission assembly 6;

[0041] A limiting assembly 8 for positioning it is arranged at the bottom end of the sliding assembly 5.

[0042] Even further, please refer to Figure 1 - Figure 3 As shown, the sliding assembly 5 includes a support frame 51. A positioning hole 52 is opened at the top end of the support frame 51. The positioning hole 52 matches the mounting rod 1. A wedge block 53 is fixedly arranged in the positioning hole 52. Positioning grooves 10 are opened at both ends of the mounting rod 1. The positioning grooves 10 match the wedge block 53 to assist the mounting rod 1 to be inserted into the positioning hole 52; when the positioning grooves 10 on the mounting rod 1 are aligned with the wedge block 53 on the support frame 51, the mounting rod 1 is smoothly inserted into the positioning hole 52 under the action of the wedge block 53;

[0043] A connecting seat 54 is fixedly arranged at the bottom end of the support frame 51, and rollers 55 are also fixedly arranged on both sides of the bottom end of the support frame 51.

[0044] Specifically, please refer to Figure 1 - Figure 2As shown in the figure, the transmission assembly 6 includes a servo motor 64 fixedly installed on the inner upper part of the mounting seat assembly 7. The output end of the servo motor 64 is fixedly connected to a second bevel gear 63. The second bevel gear 63 meshes with a first bevel gear 62. The first bevel gear 62 is fixedly connected to a bidirectional threaded lead screw 61. The two ends of the bidirectional threaded lead screw 61 are threadedly connected to the connecting seats 54. When the servo motor 64 rotates, it drives the bidirectional threaded lead screw 61 to rotate through the transmission of the second bevel gear 63 and the first bevel gear 62, thereby driving the two connecting seats 54 to move away from each other. Furthermore, it drives the support frame 51 to slide in the guide groove 73 through the rollers 55, so that the mounting rod 1 disengages from the positioning hole 52 on the support frame 51. At this time, the hydraulic rod 3 moves down the paper roll 2 to be replaced through the clamping arm 4.

[0045] Further, please refer to Figure 1 and Figure 3 As shown in the figure, the mounting seat assembly 7 includes a base 71. Guide plates 72 are fixedly provided on both sides of the base 71. A guide groove 73 is formed in the guide plates 72. Rollers 55 are slidably connected in the guide groove 73. A limiting plate 74 is fixedly provided in the guide groove 73.

[0046] In addition, please refer to Figure 5 and Figure 6 As shown in the figure, the limiting assembly 8 includes a limiting cylinder 81 fixedly provided at the bottom end of the support frame 51. A limiting rod 82 is slidably connected in the limiting cylinder 81. One end of the limiting rod 82 located inside the limiting cylinder 81 is fixedly connected to one end of a spring 83. The other end of the spring 83 is fixedly connected to the inner wall of the limiting cylinder 81. The other end of the limiting rod 82 extends outside the limiting cylinder 81.

[0047] In addition, please refer to Figure 5 As shown in the figure, a positioning plate 91 is fixedly provided on the side of the base 71. A limiting hole 92 matching the limiting rod 82 is formed in the positioning plate 91. The limiting rod 82 is of a wedge-shaped structure. And when the limiting rod 82 moves to the position of the positioning plate 91, the part of the positioning plate 91 in contact with it is set as an arc smooth structure. The limiting rod 82 at the bottom end of the support frame 51 just snaps into the limiting hole 92 on the positioning plate 91 to complete the limiting of the support frame 51.

[0048] The specific working principle is as follows:

[0049] During specific operation, when the paper roll 2 needs to be replaced, the limit rod 82 is pressed to make it enter the limit cylinder 81 to release the limit, and then the servo motor 64 is started. The servo motor 64 rotates through the second bevel gear 63 and the first bevel gear 62 to drive the bidirectional threaded screw 61 to rotate, thereby driving the two connecting seats 54 to move in reverse, and then driving the support frame 51 to slide in the guide groove 73 through the roller 55, so that the mounting rod 1 is separated from the positioning hole 52 on the support frame 51. At this time, the hydraulic rod 3 moves the paper roll 2 to be replaced through the clamping arm 4; after that, a new paper roll 2 is replaced, and then the hydraulic rod 3 moves the new one through the clamping arm 4. The paper roll 2 rises to the specified height, and the servo motor 64 is started again. Through the above steps, the bidirectional threaded screw 61 rotates in the opposite direction, so that the two support frames 51 move toward each other. When the positioning groove 10 on the mounting rod 1 is aligned with the wedge block 53 on the support frame 51, the mounting rod 1 is smoothly inserted into the positioning hole 52 under the action of the wedge block 53. At this time, the limiting rod 82 at the bottom end of the support frame 51 is just inserted into the limiting hole 92 on the positioning plate 91, completing the limiting of the support frame 51. At this point, the replacement of the paper roll 2 is completed, thereby effectively solving the problem of low efficiency of replacing the paper roll 2 in the unwinding device in the existing paper cup production.

[0050] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments.
