Description

Technical Field

[0001] The utility model relates to the technical field of printing equipment, and more specifically to a plastic product surface printing equipment. Background Art

[0002] Plastic products are molten liquids during the manufacturing process, so they can be heated to melt, pressurized to make them flow, and cooled to solidify, forming various shapes. This large and varied group of materials is called plastics. In the production process of plastic products, in order to cater to the needs of different consumers, it is necessary to print on the surface of plastic products so that the surface of plastic products can be printed with different shapes to improve their aesthetics.

[0003] When printing on a plastic water cup, the water cup is usually placed on a cup stand first, and then a lifting mechanism pushes the printed silicone downward and fits with the outside of the water cup so that the pattern on the transfer film can be transferred to the outside of the water cup. Then the worker takes down the printed water cup, and the transmission mechanism drives the printed film for transmission. During the process, the water cup needs to be loaded and unloaded manually, which is cumbersome, reduces the efficiency of printing, and has a low degree of automation. Utility Model Content

[0011] Technical effects and advantages of the utility model:

[0012] 1. The utility model is provided with a driving assembly and a blanking assembly. After printing is completed, the cylinder drives the lifting plate to move upward, thereby driving the connecting rod to move upward. In the process of the connecting rod rising, the cylindrical gear is driven to rotate clockwise through meshing with the cylindrical gear. Under the driving action of the helical teeth, the wedge block and the second rotating rod are driven to rotate clockwise, and then the rotating disk is driven to rotate clockwise. The first cylindrical block first rotates from the back of the right side of the rotating disk to the front of the right side of the first cylindrical block, and the connecting plate drives the movable plate to move toward the front, pushing the plastic water cup to separate from the water cup rack, and the printed plastic water cup falls into the inner side of the blanking frame for blanking, and then the first cylindrical block rotates from the front of the right side of the rotating disk to the back of the right side of the rotating disk, and the connecting plate drives the movable plate to move toward the back for resetting.

[0013] 2. The utility model is provided with helical teeth and a wedge-shaped block. When the lifting plate moves downward, the cylindrical gear rotates counterclockwise. When the helical teeth contact the wedge-shaped block, the left side of the wedge-shaped block deviates toward the front, and the spring is stretched, so that the helical teeth cannot drive the second rotating rod to rotate. Then, when the cylinder pushes the lifting plate to move downward, the movable plate remains in the initial reset position, which will not affect the workers from putting the plastic water cup on the water cup rack.
