Technical Field

[0001] The utility model relates to the technical field of screen printing machines, in particular to a lifting type fully automatic screen printing machine with adjustable format. Background Art

[0002] A screen printing machine is a machine that uses a silk screen printing plate to print. It is a type of printing machine. A screen printing machine is a machine that prints text and images. It is a general term for machines or equipment used to produce printed products. A screen printing machine is a more representative printing equipment among stencil printing machines. In addition to silk, the materials used to make the screen can also be nylon wire, copper wire, steel wire or stainless steel wire. It can be divided into flat screen printing machines, curved screen printing machines, rotary screen printing machines, etc.

[0003] The printing width of existing screen printing machines is mostly fixed when in use, and is only suitable for printing screens of a single specification. When the substrate is small, using a screen of fixed specifications will cause a waste of ink. Therefore, the existing screen printing machines are not convenient for replacing printing screens of different sizes, and their applicability is poor. In view of this, we propose a lifting type fully automatic screen printing machine with adjustable format. Utility Model Content

When the substrate is small, the use of a screen with a fixed specification will cause a waste of ink. Therefore, the existing screen printing machines are not convenient for replacing printing screens of different sizes and have poor applicability.

[0006] The adjustment mechanism includes a fixed slot frame, a protective box is connected to the side of the fixed slot frame, a motor is arranged inside the protective box, a positive and negative screw rod is connected to the movable end of the motor, a group of threaded blocks are sleeved on the surface of the positive and negative screw rods, and the front end of the threaded block is connected to a limiting frame.

[0007] Preferably, the fixing slot frame and the protection box are threadedly connected, and the motor is matched and embedded in the protection box.

[0008] Preferably, the forward and reverse screw rods and the threaded block are threadedly connected, and the motor forms a transmission structure through the forward and reverse screw rods, the threaded block and the limit frame.

[0011] Preferably, the guide rod vertically penetrates the top of the support bracket, and the guide rod is movably engaged with the support bracket.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. The utility model effectively drives the forward and reverse screws to rotate through the motor, thereby driving a group of threaded blocks on the surfaces of the forward and reverse screws to move away from or closer to each other, thereby realizing the adjustment of the spacing between a group of limit frames at the front ends of a group of threaded blocks.

[0023] The utility model is further described below in conjunction with the accompanying drawings and embodiments:

[0024] A fully automatic screen printing machine with adjustable width and height, see Figures 1 to 5 , comprising a body 1, a placing table 2 is provided on the surface of the body 1, a printing screen 3 is provided above the placing table 2, a group of limiting mechanisms 4 are symmetrically provided on both sides of the printing screen 3, an adjusting mechanism 5 is connected to the outer side of the limiting mechanism 4, and a coating printing component 6 is provided above the printing screen 3;

[0025] The adjusting mechanism 5 includes a fixed slot frame 501, a protective box 502 is connected to the side of the fixed slot frame 501, a motor 503 is arranged inside the protective box 502, further, the fixed slot frame 501 and the protective box 502 are threadedly connected, the motor 503 is matched and embedded in the protective box 502, the movable end of the motor 503 is connected to the forward and reverse screw rods 504, the surface of the forward and reverse screw rods 504 is provided with a group of thread blocks 505, the front end of the thread block 505 is connected to the limiting frame 506, further, the forward and reverse screw rods 504 and the thread block 505 are threadedly connected, and the motor 503 forms a transmission structure through the forward and reverse screw rods 504, the thread block 505 and the limiting frame 506. The utility model effectively drives the forward and reverse screw rods 504 to rotate through the motor 503, thereby driving a group of threaded blocks 505 on the surfaces of the forward and reverse screw rods 504 to move away from or closer to each other, thereby realizing the adjustment of the distance between a group of limit frames 506 at the front ends of a group of threaded blocks 505. Since the limit frames 506 are connected to the limit mechanisms 4, the distance between a group of limit mechanisms 4 can be effectively adjusted, making it easier for a group of limit mechanisms 4 to adapt to clamp printing screens 3 of different sizes, thereby improving the applicability of the device.

[0026] It is worth noting that the limiting mechanism 4 includes a support frame 401, a fixed cylinder frame 402 is connected to the middle end of the top of the support frame 401, a screw 403 passes through the inside of the fixed cylinder frame 402, a turntable 404 is connected to the top of the screw 403, a clamping block 405 is connected to the bottom of the screw 403, and a group of guide rods 406 are provided on both sides of the fixed cylinder frame 402. It is worth noting that the guide rod 406 vertically passes through the top of the support frame 401, and the guide rod 406 is movably engaged with the support frame 401, and a pressure plate 407 is fixedly connected to the bottom of the guide rod 406, wherein the fixed cylinder frame 402 and the screw 403 are threadedly connected, and the screw 403 forms a rotating structure with the pressure plate 407 through the clamping block 405, and the clamping block 405 is in the shape of a disc. In the utility model, the required printing screen 3 is placed between a group of supporting frames 401, and the two sides of the printing screen 3 are made to fit with the inner sides of the supporting frames 401 through the adjustment mechanism 5. Then, the turntable 404 is rotated to make the screw 403 move inside the fixed cylinder frame 402. While the screw 403 moves, it drives the pressure plate 407 to move vertically until the bottom of the pressure plate 407 contacts the surface of the printing screen 3, effectively limiting the printing screen 3. The setting of the guide rod 406 effectively maintains the stability of the pressure plate 407 during movement and reduces the shaking and deviation of the pressure plate 407.

[0027] Working principle: the operator places the printing material on the surface of the placement table 2, and selects a printing screen 3 of similar specifications according to the size of the printing material, and places the required printing screen 3 between a group of support brackets 401, and drives the forward and reverse screw rods 504 to rotate through the motor 503, thereby driving a group of threaded blocks 505 on the surface of the forward and reverse screw rods 504 to move away from or close to each other, so as to adjust the distance between a group of limit frames 506 at the front end of a group of threaded blocks 505. Since the limit frames 506 are connected to the limit mechanism 4, the distance between a group of limit mechanisms 4 can be adjusted so that the two sides of the printing screen 3 fit the inner side of the support bracket 401, and then the turntable 404 is rotated to make the screw rod 403 move inside the fixed cylinder frame 402. While the screw 403 moves, it drives the pressure plate 407 to move vertically until the bottom of the pressure plate 407 contacts the surface of the printing screen 3, limits the printing screen 3, and then starts the coating printing component 6 to complete the coating printing.
