[0001] This utility model relates to the field of screen printing machine technology, specifically to a double-sided automatic screen printing machine. Background Technology

[0002] Currently, screen printing involves first creating a screen printing plate of the text or image to be printed, which is then mounted on a screen printing machine. A squeegee then forces ink through the screen printing plate onto the substrate (such as textiles, metal plates, plastics, leather templates, glass, and ceramics), thus screen printing the same text or image as the screen printing plate onto the substrate.

[0003] The existing traditional double-sided automatic screen printing machines on the market have a linear production line layout, which means that the front screen printing station, the front baking station, the flipping station, the reverse screen printing station, the reverse baking station, and the unloading station are set up on the frame in sequence along the processing direction. The manufacturing and maintenance costs of this type of fully automatic double-sided screen printing machine are high, and the equipment occupies a lot of space, making it difficult to use in production environments with limited space.

A curing mechanism 3 is provided between the second turntable assembly 2B on the frame 1.

A material transfer mechanism 5 is provided laterally on the right side of the first turntable assembly 2A and the second turntable assembly 2B on the frame 1. A control console 6 is also provided on the frame 1. By adopting a parallel layout of dual turntable assemblies, the first and second patterns of the substrate can be screen printed independently and synchronously on the front and back of the substrate material, respectively. At the same time, the two workstations share the same material transfer mechanism and curing mechanism, which reduces the manufacturing and maintenance costs of the equipment. It not only greatly reduces the footprint of the equipment, meeting the needs of production in small spaces, but also greatly improves the efficiency and quality of screen printing.

[0027] The first turntable assembly 2A and the second turntable assembly 2B have the same structure, both including a turntable 21 for fixing and placing the transport fixture 22, a transport fixture 22 for clamping and rotating the printing substrate, and a fixture driver 23 for docking, unlocking, and driving the transport fixture 22 to rotate. The turntable 21 is rotatably mounted on the frame 1. Specifically, the turntable 21 is driven to rotate by a turntable driver located inside the frame 1, and the turntable driver is a servo motor. Multiple transport fixtures 22 are arranged in a ring at equal intervals on the turntable 21, preferably four in this embodiment.

The transport fixture 22 includes a fixture base 221, a rotating shaft 222, a fixture 223, a locking piece 224, a locking plate 225, a guide rod 226, and a spring 227. The fixture base 221 is mounted on a turntable 21. A rotating shaft 222 is laterally mounted on the fixture base 221. The outer end and inner end of the rotating shaft 222 are respectively fixed with the fixture 223 and the locking piece 224. The locking plate 225 is sleeved on the inner end of the rotating shaft 222, located between the locking piece 224 and the fixture base 221. Guide holes 221A are provided on both sides of the rotating shaft 222 on the fixture base 221. A guide rod 226 slides through each guide hole 221A. A spring 227 is sleeved on each guide rod 226 between the locking plate 225 and the fixture base 221. The fixture driver 23 outputs a spring 227 to the rotating shaft 222.

The lower end of the fixing plate 233 is fixed with a rotary driver 234 that docks with the inner end of the rotating shaft 222. Specifically, a straight-line docking protrusion 234A is connected to the output end of the rotary driver 234, and a straight-line docking groove 222A is formed in the middle of the inner end of the rotating shaft 222. The protrusion 234A and the mating groove 222A are inserted and engaged.

The fixed plate 233 is driven by the output end of the mating driver 232 to drive the rotary driver 234 and the unlocking rod 235 to move linearly towards the transport fixture 22. The unlocking rod 235 will first push the locking plate 225 to release the abutment engagement state from the locking piece 224. Then, the output end of the rotary driver 234 will be engaged with the inner end of the rotating shaft 222 and drive the rotating shaft 222 to drive the fixture 223 to complete a 180-degree rotation.
