[0002] In the field of electrical equipment manufacturing, the distribution box is an indispensable part of the power system, and the accuracy and clarity of its markings are crucial to the safe operation of the power system. Traditional methods of printing the external markings of distribution boxes are mostly manual operations, such as screen printing or manual spraying, which are not only inefficient, but also have many shortcomings.

[0003] First, manual printing is labor-intensive and inefficient, making it difficult to meet the needs of large-scale production. During the manual printing process, the printing quality is difficult to guarantee due to the different skill levels and fatigue levels of the operators, and problems such as blurred fonts and position offsets are prone to occur, affecting the aesthetics and practicality of the distribution box. Secondly, the traditional printing method has a serious waste of ink during the ink dipping and printing process, which not only increases production costs, but also causes certain pollution to the environment. In addition, due to the volatility and flammability of ink, manual printing also has certain safety hazards.

[0004] Finally, with the continuous development of the power system, the requirements for the external markings of the distribution box are getting higher and higher. The traditional printing method is difficult to meet the requirements for the clarity, durability and aesthetics of the markings, especially in some special environments, such as high temperature, high humidity, corrosion, etc., the markings of the traditional printing method are easy to fall off or blur, which brings hidden dangers to the safe operation of the power system.

[0039] The pad printing mechanism 5 includes a sliding seat 502 movably mounted on a frame, the sliding seat reciprocates between the pad printing steel plate mold and the printing operation area, a pad printing rubber head that can be raised and lowered is mounted on the sliding seat, the pad printing rubber head corresponds to the pad printing steel plate mold one by one, and is used to transfer the printing pattern on the printing mold to the product to be printed in the printing operation area; wherein the pad printing mechanism includes a supporting hanger 501 mounted on the frame, the supporting hanger is located above the printing operation area and the ink dipping area, the sliding seat 502 is slidably mounted on the supporting hanger, the sliding seat moves relative to the ink dipping area and the printing operation area, a pad printing rubber head seat 503 is movably mounted on the sliding seat, the pad printing rubber head seat moves vertically relative to the sliding seat, and the pad printing rubber head 504 is mounted on the pad printing rubber head seat 503; the pad printing mechanism cleverly integrates the sliding seat and the pad printing rubber head seat above the printing operation area and the ink dipping area through the design of the supporting hanger, making the entire pad printing process more compact and efficient. This design not only reduces the floor space, but also improves the overall operating efficiency of the equipment. The structure design of the pad printing mechanism is reasonable, and the components are closely matched and easy to disassemble, which makes the maintenance and maintenance of the equipment easier and reduces the maintenance cost. At the same time, the standardized design of each component also makes replacement and maintenance more convenient and quick.

[0040] In order to achieve flexible sliding, a transverse slide rail 505 is installed on the support hanger along the sliding direction of the sliding seat, a transverse slider 506 cooperating with the transverse slide rail 505 is installed on the sliding seat, a lifting guide rail 507 is installed on the sliding seat along the lifting direction of the pad printing rubber head, and a lifting slider 508 cooperating with the lifting guide rail is installed on the pad printing rubber head.
