[0002] In a traditional four-color pad printing machine, such as the shuttle table disclosed in ZL201920184618 published by the Chinese Patent Office, since the shuttle table is a processing method of a single workbench, during the four-color pad printing process, at least two groups of pad printing devices must be in a standby state and cannot be put into use continuously, resulting in low processing efficiency. On the one hand, it leads to low overall efficiency utilization of the machine, and also causes the processing personnel next to it to have a large idle waiting time, resulting in increased personnel cost;

[0003] In addition, when using a rotating disk, the longitudinal length of the rotating disk results in a large rotation radius, and the existence of four sets of printing plates distributed in a rectangular shape does not allow the rotating disk with two sets of workbenches to rotate as wide as under the original two-color conditions. The adjustment of its overall structure leads to major changes in the structure of the entire machine and the system program, which greatly increases the equipment cost and makes the overall equipment more bloated.

[0034] Optionally, a transmission gear 100 is disposed between the first rack 103 and the second rack 104 and is meshed with the first rack 103 and the second rack 104 respectively.

[0035] As an option, a rack transmission member is provided to transmit the relative movement of the first rack 103 or the second rack 104 .

[0036] Structure 1: Optionally, the rack transmission member includes a transmission motor, and the transmission shaft of the transmission motor drives the transmission gear 100 to rotate to drive the first rack 103 or the second rack 104 to move relative to each other.

[0038] Based on the above embodiments, due to the existence of the transmission gear 100, when the transmission gear 100 rotates, the first rack 103 and the second rack 104 move synchronously, thereby realizing the movement, contraction and expansion and sliding of the first worktable 11 and the second worktable 12 in the mating direction.

[0039] Optionally, the first linking member 105 or the second linking member 106 is disposed on the upper surface of the corresponding first rack 103 or the second rack 104 between the first workbench 11 and the second workbench 12 .

[0047] Optionally, the first workbench and / or the second workbench are provided with a recess for accommodating the product to be printed, and the product to be pad printed can be placed in the recess.

In a preferred implementation, when the first workbench and the second workbench on the base are retracted and rotated and then opened toward each other, the first workbench and the second workbench can be controlled to open gradually through program settings when the space gradually allows opening, thereby improving the overall efficiency.

[0050] Based on this embodiment, during the pad printing process, four groups of pad printing devices can work synchronously and sequentially at the same time, and two workbenches can be put into use at the same time, thereby improving the overall efficiency of pad printing.

[0051] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
