Technical Field

[0001] The utility model relates to the field of screen printing machines, in particular to a screen printing machine with an improved structure. Background Art

[0002] A screen printing machine is a machine for printing characters and images, and is a general term for machines or equipment used for producing printed products. The screen printing machine belongs to a relatively representative printing device in the stencil printing machine. The materials for making the screen can be nylon filaments, copper wires, steel wires or stainless steel wires in addition to real silk. The screen frame lifting mechanism of the existing screen printing machine is usually arranged above the frame, resulting in a relatively large overall volume of the screen printing machine and affecting the operation on the surface of the machine table.

[0003] To solve the above problems, a screen printing machine with an improved structure is thus proposed here. Summary of the Utility Model

The bottom ends of the four moving rods are fixedly connected with support columns. A rack is fixedly connected to one side of each of the four support columns. Support seats are fixedly connected to both sides of the bottom end of the inner wall of the frame. Rotating seats are fixedly connected to the top of the four support seats. A rotating shaft is rotatably arranged between the two rotating seats on the same side. Connecting rods are fixedly connected to both ends of the two rotating shafts. A first gear is fixedly connected to one end of each of the four connecting rods away from the rotating shaft.

[0006] The screen printing machine modifies the lifting mechanism of the screen frame to the inside of the frame, and drives two second gears to rotate through two second motors. Since the two toothed rings are respectively meshed with the two second gears, it is convenient to drive the two toothed rings and the two rotating shafts to rotate, thereby driving the four first gears to rotate. Since the four first gears are respectively meshed with the four racks, the four racks are driven to move up and down, thereby driving the four moving rods to move up and down, and then realizing the lifting adjustment of the screen frame. This kind of lifting design can reduce the overall occupied space of the screen printing machine, thereby reducing its volume, and can improve the operation space on the surface of the machine table, making the operation more convenient.

[0007] Preferably, two fixing seats are fixedly arranged in the middle of the bottom end of the inner wall of the frame. Motors are fixedly installed on the inner sides of the two fixing seats. Output ends of the two motors are fixedly connected with second gears. Tooth rings are fixedly arranged on the surfaces of the two rotating shafts. The two tooth rings are respectively meshed and connected with the two second gears. By driving the two second gears to rotate through the two second motors, since the two tooth rings are respectively meshed and connected with the two second gears, it is convenient to drive the two tooth rings and the two rotating shafts to rotate, thereby driving the four first gears to rotate.

[0008] Preferably, two mounting seats are arranged at the bottoms of both sides of the inner wall of the frame. Auxiliary wheels are rotatably arranged in the middles of the four mounting seats. The four auxiliary wheels are correspondingly arranged with the four support columns. The arrangement of the auxiliary wheels facilitates the stable up and down movement of the four support columns.

[0009] Preferably, moving grooves are formed at the joints of the frame and the four moving rods. The arrangement of the moving grooves facilitates the up and down, front and back movement of the moving rods.

[0010] Preferably, two sleeves are fixedly arranged at the bottom ends of the two mounting frames. Support rods are inserted through the bottoms of the four sleeves. Guide rails are fixedly arranged at the top ends of the two mounting frames. Guide seats are slidably arranged on the surfaces of the two guide rails. Connecting seats are fixedly arranged on both sides of the top ends of the two guide seats. A machine head is fixedly arranged at the top between the four connecting seats. Cylinders are fixedly installed on one sides of the two mounting frames. The movable ends of the two cylinders are fixedly connected with mounting pieces. The two mounting pieces are respectively fixedly connected with the two guide seats. The arrangement of the four connecting seats facilitates the connection of the two guide seats with the machine head. By pushing the two mounting pieces to move back and forth through the two cylinders, the two guide seats are driven to move back and forth, thereby driving the machine head to move back and forth.

[0011] Preferably, the four first gears are respectively meshed and connected with the four racks.

[0012] Preferably, universal wheels are fixedly connected to the bottom ends of the four support rods. The arrangement of the universal wheels facilitates the transportation of the silk screen printing machine.

[0014] 1. The lifting mechanism of the screen printing machine is modified to the inside of the frame, and two second motors are used to drive two second gears to rotate. Since two toothed rings are respectively meshed and connected with the two second gears, it is convenient to drive the two toothed rings and two rotating shafts to rotate, thereby driving four first gears to rotate. Since the four first gears are respectively meshed and connected with the four racks, the four racks are driven to move up and down, thereby driving the four moving rods to move up and down, and then realizing the lifting adjustment of the screen frame. This kind of lifting design can reduce the overall occupied space of the screen printing machine, thus reducing its volume, and can improve the operating space on the surface of the machine table, making the operation more convenient.

[0015] 2. Two cylinders are used to push two mounting parts to move back and forth, thereby driving two guide seats to move back and forth along the two guide rails respectively, and then driving four connecting seats to move back and forth, and then driving the machine head to make automatic telescopic movement, which is convenient for the operation.
