Description

Technical Field

[0001] The present invention relates to the technical field of product processing machinery research and development design, and in particular to a turntable and a pad printing machine used for product processing. Background Art

[0002] The pad printer is suitable for printing on plastics, toys, glass, metals, ceramics and other products. The products to be printed are transported to the bottom of the pad printer through a turntable, and the positioning components are used to position the station on the turntable where the products to be printed are placed. Then, the printing components of the pad printer are used to print the products to be printed on the station.

[0003] Turntables are widely used in the production and processing of products, and have made significant contributions to the automation and self-energization of products in the manufacturing industry, becoming a major component in promoting product automation in production;

[0004] The existing workpiece turntable suitable for the pad printing industry usually positions the placement station on the conveying device by arranging a positioning cylinder on one side or both sides of the outer periphery of the base. The positioning cylinder can only be positioned by two points, and has poor applicability. In addition, the impact force is strong when positioning the placement station, which will produce large vibrations. After long-term work, the positioning cylinder is easily damaged, making it impossible for the positioning cylinder to effectively position the placement station, thereby affecting the processing efficiency of the product and increasing the replacement cost of the positioning cylinder. The positioning cylinder of this turntable is arranged on the outer periphery of the base, thereby increasing the volume of the turntable, and a certain amount of movable space needs to be reserved for the positioning cylinder during the operation of the turntable. The turntable in the prior art has high cost and is difficult to maintain, and needs to occupy a large space, resulting in low space utilization. Therefore, it is necessary to further improve and upgrade the existing technology. Summary of the invention

[0005] The purpose of the present invention is to provide a turntable for product processing designed to solve at least one technical problem in the background technology.
