specific Embodiment 1

[0051] Such as Figure 1 to Figure 7 As shown, when the screen printer of this embodiment is in use, the screen plate 700 is fixed, and the thermal print head 400 and the rubber roller assembly 500 move synchronously to print the desired pattern on the screen of the screen plate 700 .

[0052] The screen printer includes a base 100 on which a movable mounting frame 200 is slidably installed. The sliding direction of the movable mounting frame 200 is defined as the left-right direction, and the horizontal direction perpendicular to the left-right direction is the front-rear direction. Such as figure 1 As shown, guide rods 31 are fixed on the base 100 , the guide rods 31 extend left and right, and there are two guide rods 31 arranged at intervals along the front and rear directions. A sliding sleeve is fixedly installed on the bottom of the movable mounting frame 200, and the sliding sleeve is guided and sleeved on the guide rod 31, so that the movable mounting frame 200 can gu...

Embodiment 1

[0070] In Example 1, the screen fixing structure achieves positioning and clamping through the left and right positioning parts, front and rear positioning parts and quick clamps. In this embodiment, the clamping direction of the quick clamps can be up and down. When pressing up and down, the fast There are at least two clamps.

specific Embodiment 3

[0072] In Embodiment 1, by setting support plates, the left and right sides of the rubber roller support the screen upwards, and the rubber roller presses the screen downward to form a fit to ensure that the rubber roller exerts sufficient pressure on the screen to ensure the printing effect. In this embodiment, the support plate can be omitted, and only the rubber rollers can be used for pressing.

Abstract

The invention relates to a screen printer. The screen printer comprises a base and a screen frame fixing structure used for fixing a screen frame to the base; a screen fixing structure comprises a pressing piece for pressing the screen frame; the screen printer further comprises a movable installing frame which is guided in the left-right direction and slidably assembled on the base; the movable installing frame is provided with a thermosensitive printing head, a rubber covered roller installing frame is movably assembled on the movable installing frame, and a rubber covered roller is rotationally installed on the rubber covered roller installing frame and extends in the front-back direction; the interior of the rubber covered roller installing frame is provided with avoiding channels located outside the front side and the rear side of the rubber covered roller, and the avoiding channels are used for allowing side edges, extending in the left-right direction, in the screen frame to penetrate through in the left-right direction; the moving stroke of the rubber covered roller installing frame comprises a working station, close to the thermosensitive printing head, of the rubber covered roller and further comprises an installing station, away from the thermosensitive printing head, of the rubber covered roller; and the screen printer further comprises a holding structure which isused for holding the rubber covered roller installing frame in the working station.

Description

technical field [0001] The invention relates to a screen printer. Background technique [0002] The screen plate includes a screen frame and a screen tightly fixed in the screen frame. The current screen printing process mostly uses photosensitive photographic plate making, and the positive film containing images or letters is placed on a screen coated with photosensitive emulsion. The photosensitive emulsion will harden after being irradiated by light. When irradiated with strong light, the part of the screen that is not blocked by the positive film hardens, and the part that is not exposed to light does not harden. The unhardened emulsion is then developed to reveal the images or letters transferred from the positive to the screen. However, the production process of photosensitive plate making is more complicated. [0003] The Chinese utility model patent with the authorized announcement number CN203305636U discloses a heat-sensitive screen, which prints the required ima...
