Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of screen printing, in particular to a screen plate position adjustment mechanism. Background Art
[0002] Screen printing refers to the use of silk screen as a base and the use of photosensitive platemaking to make a screen printing plate with images. Screen printing consists of a screen printing plate, a scraper, ink, a printing table and a substrate. The screen printing plate is the screen. Printing is based on the basic principle that the mesh holes in the image part of the screen printing plate can pass through the ink, while the mesh holes in the non-image part cannot pass through the ink. When printing, ink is poured into one end of the screen printing plate, and then a scraper is used to apply a certain amount of pressure to the inked part of the screen printing plate. At the same time, it moves at a constant speed toward the other end of the screen printing plate. During the movement, the ink is squeezed from the mesh holes in the image part by the scraper and transferred to the substrate, thus completing the printing work. During the printing process, the screen printing plate of the corresponding specifications and sizes is generally replaced first, and then the position of the screen printing plate is fixed by gluing to prevent the printing quality from being affected by the position shift of the screen printing plate during the printing process. Although the gluing and fixing operation is simple and convenient, the gluing and fixing effect gradually fails during long-term use, which can easily cause the screen printing plate to loosen and fall off accidentally, thereby affecting work efficiency and work quality.

[0022] The present invention is described in detail below with reference to the accompanying drawings.
[0023] like Figures 1 to 2As shown, a screen position adjustment mechanism of the present invention includes a machine base 1, an adjusting component 2 movably arranged on the machine base 1 and a driving component 3 driven and connected to the adjusting component 2, the adjusting component 2 includes a base 21, a first clamping groove 22 and a second clamping groove 23 movably arranged on the base 21, a first nut 24 and a second nut 25 respectively arranged in the first clamping groove 22 and the second clamping groove 23, a first screw 26 and a second screw 27 respectively threadedly connected to the first nut 24 and the second nut 25, and a first clamping block 28 and a second clamping block 29 respectively arranged in the first screw 26 and the second screw 27, the first clamping groove 22 and the second clamping groove 23 are close to or away from each other along the length direction of the base 21.
[0024] During operation, the driving component 3 drives the adjusting component 2 to move horizontally along the length direction of the machine base 1, thereby adjusting the adjusting component 2 to a suitable position, and the first clamping groove 22 and the second clamping groove 23 are close to or away from each other along the length direction of the base 21. When fixed, the mesh plate is placed between the first clamping groove 22 and the second clamping groove 23, and the outer side and the bottom of the mesh plate are both engaged and fixed to the inner wall of the first clamping groove 22 and the inner wall of the second clamping groove 23. By rotating the first screw 26 clockwise and making the first screw 26 threadedly connected to the first nut 24, the first clamping block 28 is driven to move downward, further prompting the first clamping block 28 to be clamped and fixed to the top of the mesh plate, and by rotating the second screw 27 clockwise and making the second screw 2 7 is threadedly connected to the second nut 25, thereby driving the second clamping block 29 to move downward, further prompting the second clamping block 29 to be clamped and fixed on the top of the screen, thereby fixing the screen in multiple directions, reducing the possibility of the screen being offset, and improving printing quality. When the screen needs to be replaced, the first screw 26 is rotated counterclockwise and the first screw 26 is moved away from the first nut 24, thereby driving the first clamping block 28 to move upward and away from the screen. The second screw 27 is rotated counterclockwise and the second screw 27 is moved away from the second nut 25, thereby driving the second clamping block 29 to move upward and away from the screen, thereby facilitating the removal of the screen and improving practicality and connection reliability. The utility model realizes adaptive adjustment of the clamping position of screens of different specifications and sizes, ensures accurate positioning of the screen, has good positioning effect, and improves work efficiency and work quality.
[0025] In this embodiment, the first clamping groove 22 and the second clamping groove 23 are both C-shaped. The first clamping groove 22 is provided with a first slider 210, and the second clamping groove 23 is provided with a second slider 211. The base 21 is laterally provided with a guide rail 212. The first clamping groove 22 is slidably connected to the guide rail 212 via the first slider 210, and the second clamping groove 23 is slidably connected to the guide rail 212 via the second slider 211. Specifically, the first clamping groove 22 and the second clamping groove 23 are both C-shaped, which can better wrap the outer edge of the supporting mesh plate and enhance positioning stability. The first clamping groove 22 is slidably connected to the guide rail 212 via the first slider 210, and the second clamping groove 23 is slidably connected to the guide rail 212 via the second slider 211, and the movement is smooth and stable.
[0026] In this embodiment, both ends of the base 21 are provided with limit blocks 213, which block and interfere with the first slider 210 and the second slider 211. Specifically, the limit blocks 213 are installed at both ends of the base 21. When the first clamping groove 22 and the second clamping groove 23 slide on the base 21, the limit blocks 213 block and interfere with the first slider 210 and the second slider 211, thereby providing a good blocking and limiting function, effectively preventing the first slider 210 and the second slider 211 from accidentally falling off the guide rail 212 due to excessive sliding, thereby improving work safety performance.
[0027] The drive assembly 3 of this embodiment includes a ball screw 31, a servo motor 32 drivingly connected to the ball screw 31, a screw nut 33 threadedly connected to the ball screw 31, a movable base 34 connected to the screw nut 33, and a connector 35 provided on the movable base 34, wherein the movable base 34 is connected to the base 21 via the connector 35. Specifically, the servo motor 32 drives the ball screw 31 to rotate, and the rotating ball screw 31 drives the screw nut 33 to move, thereby driving the movable base 34 connected to the screw nut 33 to move, and the movable base 34 is connected to the base 21 via the connector 35, thereby enabling the drive assembly 3 to drive the adjustment assembly 2 to move horizontally along the machine base 1, with a high degree of intelligence.
[0028] In this embodiment, an ion wind bar 4 is provided on the side of the base 1 away from the adjustment assembly 2. Specifically, the ion wind bar 4 is provided on the back of the base 1. When in operation, the ion wind bar 4 generates air masses with positive and negative charges, which effectively neutralize the charge on the surface of the screen, achieving the purpose of eliminating static electricity and improving printing quality.
