A first clamping sleeve 431 is provided at the bottom end of the hanger 43. A fourth driving rod 44 is vertically provided on the bottom surface of the hanger 43. The bottom end of the fourth driving rod 44 is connected to a second clamping sleeve 441. The second clamping sleeve 441 is relatively placed on the inner side of the first clamping sleeve 431. The upper die head 46 is concentrically and vertically slidably placed in the upper die ring 45. The top surface of the upper die head 46 is symmetrically provided with a second clamping block 461, and the top surface of the upper die ring 45 is symmetrically provided with a first clamping block 451.

[0061] The lower die assembly 6 includes a lower die head 64, a first lower die ring 65 and a second lower die ring 66. The second lower die ring 66 is fixed in the processing table 5 and is relatively placed directly below the upper die ring 45. The first lower die ring 65 is concentrically and vertically slidably mounted inside the second lower die ring 66. The lower die head 64 is concentrically and vertically slidably mounted inside the first lower die ring 65. The first lower die ring 65 is relatively placed directly below the upper die head 46.

[0062] The stamping machine includes the following processing modes:

[0063] In the first mode, the upper die head 46 is concentrically placed in the upper die ring 45, and the second clamping sleeve 441 is synchronously engaged with the first clamping block 451 and the second clamping block 461; the top surface of the lower die head 64 is flush with the top surface of the first lower die ring 65, and the first lower die ring 65 is placed on the inner bottom of the second lower die ring 66. The lower die head 64 and the first lower die ring 65 are synchronously lifted and lowered to stamp and process the large outer diameter paper tray;

[0064] In the second mode, the second ferrule 441 is engaged with the second block 461, and the first ferrule 431 is engaged with the first block 451; the top surface of the first lower die ring 65 is flush with the top surface of the second lower die ring 66, and the lower die head 64 is placed at the inner bottom of the first lower die ring 65. The lower die head 64 is independently raised and lowered to stamp and process a small outer diameter paper tray.

[0065] In the above scheme:

[0066] 1. The paper feeding assembly can receive the paper to be stamped and automatically transfer the paper to the processing table; there are multiple groups of paper feeding assemblies, and multiple groups of paper feeding assemblies circulate to achieve continuous processing;

[0067] 2. The paper tray unloading component can receive the stamped paper tray, and the paper tray can be automatically transferred to the unloading conveyor belt, and the unloading conveyor belt can output the paper tray to the packaging area;

[0068] 3. Both the upper die assembly and the lower die assembly are set with a multi-level adjustment structure, which can be adjusted according to the outer diameter of the processed paper tray to meet the stamping needs of paper trays with multiple outer diameters. At the same time, there is no need to stop the machine to ensure the continuity of production, which solves the problem that the current stamping equipment can only process paper trays with one outer diameter. The details are as follows:

[0069] The upper die assembly is designed with a double-stage composite structure of an upper die head and an upper die ring. The length of the second ferrule is greater than that of the first ferrule, and the fourth drive rod is the main driving structure for pressing down. When punching a paper tray with a large outer diameter, the second ferrule is clamped on the first clamping block and the second clamping block, so that the fourth drive rod can synchronously drive the upper die head and the upper die ring to press down synchronously. When punching a paper tray with a small outer diameter, the second bidirectional drive seat drives the hanger to move inward, so that the first ferrule is clamped on the first clamping block to prevent the upper die ring from falling, and the second ferrule moves inward and only clamps the second clamping block. In this way, when the fourth drive rod is extended outward, it can only drive the upper die head to descend for punching.

[0070] The lower die assembly needs to be changed to match the stamping structure, and it is also necessary to ensure that the paper tray can be unloaded normally. A three-level composite structure of the lower die head, the first lower die ring and the second lower die ring is designed. The first lower die ring and the lower die head can be raised and lowered synchronously, and the lower die head can also be raised and lowered independently. When stamping a paper tray with a large outer diameter, the second lower die ring is the lower cavity, and when stamping a paper tray with a small outer diameter, the first lower die ring is the lower cavity. The lower die head can support the paper tray from the bottom to ensure the stamping effect.

[0071] In this embodiment, the central support assembly 1 includes a central column 11, a lower rotating sleeve 12 is rotatably mounted on the middle part of the outer wall of the central column 11, a matching gear ring 121 is provided at the bottom of the outer wall of the lower rotating sleeve 12, a first motor 13 is provided on the outer wall of the central column 11, and the output end of the first motor 13 is meshed and connected to the matching gear ring 121; a second motor 14 is provided at the top of the central column 11, and an upper rotating sleeve 15 is provided at the output end of the second motor 14; the outer wall of the upper rotating sleeve 15 is provided with a paper feeding assembly 2 arranged in a circular array, and the outer wall of the lower rotating sleeve 12 is provided with a paper support unloading assembly 3 arranged in a circular array.

[0072] In the above scheme: the first motor drives the lower rotating sleeve to rotate, thereby driving the paper support unloading component to rotate and switch, and the second motor drives the upper rotating sleeve to rotate, thereby driving the paper loading component to rotate and switch.

[0073] In this embodiment, the paper feeding assembly 2 includes a movable rod 21, a first driving rod 22, a second driving rod 23, an end frame 24, a comb frame 25, and a first bidirectional driving seat 26; the movable rod 21 is fixed to the outer wall of the central column 11, the top of the movable rod 21 is provided with a first driving rod 22, the first driving rod 22 is used to drive the movable rod 21 to extend and retract, the outer end of the movable rod 21 is vertically provided with a first bidirectional driving seat 26, the outer wall of the first bidirectional driving seat 26 is symmetrically slidably installed with a closing block 27, the inner wall of the closing block 27 A stopper 28 is provided on the top, and a second driving rod 23 is symmetrically provided on the top surface of the first bidirectional driving seat 26. The outer end of each group of second driving rods 23 is connected to a group of end frames 24. The end frames 24 are placed parallel to the outside of the closing block 27. A comb frame 25 is vertically provided on the inner wall of the end frame 24, and the closing block 27 is slidably mounted on the comb frame 25. When the paper is loaded, the paper is stacked on the two groups of comb frames 25 that are closed, and the closing block 27 moves inward to restrain the paper; when the paper is unloaded, the comb frame 25 moves outward and opens, so that the stacked paper falls into the lower mold assembly 6.

[0074] In the above scheme:

[0075] 1. When feeding, the comb frame can hold up the paper from the bottom, and the second driving rod drives the closing block to close the paper toward the middle to ensure the feeding accuracy. The stopper can restrain the paper to prevent the paper from warping when rotating the feeding;

[0076] 2. When unloading, the first bidirectional driving seat drives the combing frame to move outward, and the closing block stops the paper to prevent the paper from moving with it.
