Description

Technical Field

[0001] This utility model relates to the field of tooling and fixture technology, and in particular to a tooling and fixture for a pad printing machine. Background Technology

[0002] Currently, most pad printing machines on the market are single-color or multi-color machines, which are still some distance from the injection molding workshop. When products need to be printed, they still need to be transported from the injection molding workshop to the printing workshop, which requires manpower and factory space. Moreover, when products require multi-sided printing, multiple different pad printing machines need to be changed to complete the task. This not only requires more manpower and more machines, but also causes inaccurate color registration due to the use of a set of fixtures on each machine, resulting in low efficiency.

[0003] To address the aforementioned issues, we propose a tooling fixture for pad printing machines. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a pad printing machine tooling fixture to solve the technical problems in the existing technology that "most pad printing machines on the market are single-color or multi-color machines, which are still some distance from the injection molding workshop. When products need to be printed, they must be transported from the injection molding workshop to the printing workshop, which requires manual labor and factory space; moreover, when products require multi-sided printing, multiple different pad printing machines need to be changed to complete the task, which not only requires more manual labor and more machines, but also causes inaccurate color registration and low efficiency due to the use of a set of fixtures on each machine".

[0031] The rotary worktable 4 includes a mounting shell 401, a first rotating clamping plate 402, a support plate 403, a second rotating clamping plate 404, and worktables 405 and 406. The mounting shell 401 is fixedly mounted on the upper surface of the connecting plate 1107. An automatic lifting motor 14 is fixedly mounted on the side wall of the mounting shell 401. The output end of the automatic lifting motor 14 passes through the side wall of the mounting shell 401 and is connected to the worktable 405. The worktable 405 overlaps the upper surface of the mounting shell 401. The support plate... Two support plates 403 are symmetrically and fixedly installed on the upper surface of the workbench 405.

A second rotating clamping plate 404 is rotatably connected to the center of the first rotating clamping plate 402. By rotating the tightening handle 1501, the tightening handle 1501 drives the screw to rotate and tighten the screw, so that the abutment at the other end of the screw abuts against the product, and the product is clamped in conjunction with the second rotating clamping plate 404.

[0032] The clamping mechanism 15 includes a tightening handle 1501, a tightening block 1502, and a bearing plate 1503. The lower end of the bearing plate 1503 is L-shaped and fixed to the lower end face of the second rotating clamp 404. The tightening block 1502 is fixedly installed on one side of the upper end of the bearing plate 1503. A tightening screw is transversely inserted in the tightening block 1502. One end of the tightening screw is fixedly installed on the tightening handle 1501, and the other end of the tightening screw passes through the side wall of the tightening block 1502 and the bearing plate 1503 and is fixedly connected to an abutment.

The output end of the first commutator 502 is fixedly connected to 406, and the input end of the first commutator 502 is fixedly connected to the first rotating motor 501. The first rotating motor 501 drives the first commutator 502 to start through its output end. The output end of the first commutator 502 drives the first rotating clamp 402 to rotate. The first rotating clamp 402 drives the second rotating clamp 404 to rotate, thereby adjusting the position of the printed product.

The second rotating motor 1201 starts the second commutator 1202 through its output end. The output end of the second commutator 1202 drives the second rotating clamp 404 to rotate, which can further adjust the position of the product between the second rotating clamp 404 and the screw abutment.

[0038] The pad printing host 1 is equipped with an ink tray 2 and an independent printing head 9. The ink tray 2 is used to hold ink for printing products, and the independent printing head 9 is used for printing products.

[0039] The stepper motor 1101 is started by controlling the touch screen 8. The output end of the stepper motor 1101 drives the lead screw 1108 to rotate, so that the shuttle block 1106 carries the limit plate 1105 and moves back and forth along the guide rail 1102. The limit plate 1105 drives the mounting shell 401 on the connecting plate 1107 to move back and forth. The position of the second rotating clamp 404 can be adjusted according to production needs, which is flexible and convenient.

[0040] By rotating the tightening handle 1501, the screw is rotated and tightened, so that the abutment at the other end of the screw presses against the product. This, together with the second rotating clamp 404, clamps the product, making printing easier.

[0041] Simultaneously, the first rotary motor 501 is started via the touch screen 8. The first rotary motor 501 drives the first commutator 502 to start via its output end. The output end of the first commutator 502 drives the first rotating clamp 402 to rotate. The first rotating clamp 402 drives the second rotating clamp 404 to rotate, adjusting the position of the printed product. The second rotary motor 1201 starts the second commutator 1202 via its output end. The output end of the second commutator 1202 drives the second rotating clamp 404 to rotate, which can further adjust the position of the product between the second rotating clamp 404 and the screw abutment, thus improving the applicability of this tooling fixture.

[0042] This invention first takes the product to be printed out of the injection molding machine and then cuts the sprue 10 through the loading robot 6. Then it is placed in the shuttle clamp 4 and rotated by the first rotary motor 501 and the second rotary motor 1201 to complete the multi-station multi-color printing. The printing is completed by the independent printing head 9. Then the unloading robot 7 is unloaded onto the production line for packaging.
