The left side of the clearance space of the horizontal support plate of the base fixes the scraper and the ink return plate through the scraper frame, and the scraper and the ink return plate are located above the screen of the screen frame;

The guide rail on the right side of the space for the horizontal support plate of the base is connected to the sliding seat, and the sliding seat is horizontally connected to the rotating shaft of the sliding seat through the bearing, and the rotating shaft of the sliding seat is consistent with the axis of the rotating shaft of the fixed seat, and the moving direction of the sliding seat on the guide rail is the same Parallel to the axis of the fixed seat rotating shaft; the sliding seat rotating shaft on the left side of the sliding seat is sleeved with a fixed movable splint, and the sliding seat rotating shaft on the right side of the sliding seat is sleeved with a fixed handle;

The bottom of the bracket is a horizontal support plate. There are threaded holes on the horizontal support plate of the bracket. The product installation frame is fixed on the upper surface of the horizontal support plate of the bracket. A rotating motor is arranged under the horizontal support plate of the bracket. The output of the rotating motor The screw is fixed at the front end of the shaft, and the screw is threaded into the threaded hole of the horizontal support plate of the bracket. The rotating motor controls the vertical movement of the bracket up and down. When moving straight, the sliding seat is driven to slide horizontally through the connecting rod.

work process:

Before printing, the bracket is located at the lower position of the screw stroke, and the cylindrical product is placed horizontally on the product mounting frame of the bracket, and the product is lifted up by rotating the motor to control the bracket, and at the same time, the bracket drives the sliding seat to the fixed seat through the connecting rod. Sliding on one side; when the cylindrical product moves upward until the side wall contacts the wire mesh of the wire mesh frame, the sliding seat slides to the side of the fixed seat to make the fixed splint on the right side of the fixed seat and the movable splint on the left side of the sliding seat Clamp both ends of the cylindrical product; rotate the handle fixed to the rotating shaft of the sliding seat to drive the cylindrical product, the splint fixed to the rotating shaft of the fixed seat and the gear to rotate synchronously, and the rotation of the gear makes the toothed rack meshed with it compressed backward The spring, and the screen frame fixed to the rack move backward relative to the scraper, so that the screen in the screen frame can perform annular printing on the cylindrical product that is in rolling contact with the lower end. When the screen moves to its end and the scraper is opposite At the right time, one printing is completed. Release the handle, and the rack moves forward under the action of the spring, driving the screen frame fixed with the rack to move forward relative to the ink return plate, and returns ink to the screen. The bracket is controlled to move downward by rotating the motor, and at the same time, the bracket drives the sliding seat to slide to the opposite side of the fixed seat through the connecting rod, so that the fixed splint on the right side of the fixed seat and the movable splint on the left side of the sliding seat release the clamping of the cylindrical product. At both ends, remove the printed cylindrical product, replace the printed cylindrical product and complete the printing again according to the above operation.

Beneficial effect:

The screen printing machine of the utility model realizes the screen printing of cylindrical products, greatly improves the printing quality, and can adapt to the assembly line operation of products, and can meet mass production; it reduces labor intensity and operation difficulty ,Improved work efficiency.
