Description

Technical Field

[0001] The utility model relates to the field of printing, in particular to a cleaning device for screen printing. Background Art

[0002] A screen printer is a machine for printing text and patterns. Generally, silk, nylon, copper, steel and stainless steel wires are used to make screens. When making screens, holes are left on the screen that allow ink to pass through. The holes are the patterns that need to be printed. When printing, the screen is pressed against the printing material, and the ink is scraped through the holes in the screen and printed on the printing material. Because ink dries easily, the screen needs to be cleaned in time after use. If it is not cleaned in time, the ink will remain on the screen and affect the next printing effect.

[0003] It is difficult to clamp and fix the wire mesh frame during cleaning with a traditional wire mesh cleaning device, resulting in poor stability of the wire mesh frame during brushing, making it inconvenient to brush the wire mesh frame more quickly. The brushing position of the soft-bristle brush roller is relatively fixed, and it is difficult for the soft-bristle brush roller to clean the ink contained in the mesh of the wire mesh frame. Utility Model Content

[0004] In order to overcome the shortcomings of the above-mentioned background technology, a cleaning device for screen printing is provided, which can more fully brush the ink on the surface of the screen frame. The screen frame can be clamped and fixed during cleaning, which is convenient for brushing the screen frame more quickly and is beneficial for brushing the ink contained in the mesh of the screen frame clean.

[0005] A cleaning device for screen printing, comprising a table frame, a mounting frame, a slide rail, an electric slider, a straight groove frame, a movable block, a supporting spring, a rotating shaft, a soft brush roller and a guide frame. The mounting frame is installed on the top of the table frame, and the screen frame is placed on the top of the table frame. Two slide rails are installed on the upper part of the mounting frame, and the two slide rails are symmetrically arranged. Each slide rail is slidably connected to an electric slider, and a straight groove frame is fixedly connected to the bottom of each electric slider. A movable block is slidably connected to the middle of each straight groove frame, and a supporting spring is connected between each movable block and the straight groove frame. A rotating shaft is rotatably connected to the two movable blocks, and a soft brush roller is slidably connected to the rotating shaft. The soft brush roller is centrally arranged, and guide frames are fixedly connected to both sides of the mounting frame. The two guide frames are symmetrically arranged, and the top of the rotating shaft contacts the bottom of the guide frame. The rotating shaft, the soft brush roller and the guide frame are all located on the top of the screen frame.

[0006] Furthermore, it also includes a support frame, a rack and a gear, wherein one side of a movable block is fixedly connected to the support frame, and the side of the mounting frame close to the support frame is slidably connected to the rack, a straight groove is opened in the middle of the rack, the support frame and the straight groove of the rack are slidably connected, and a gear is installed on the side of the rotating shaft close to the support frame, and the gear is meshed with the rack.

[0007] Furthermore, it also includes a movable frame, a return spring, a connecting rod, a torsion spring and a pressure plate. The movable frames are slidably connected to both sides of the lower part of the mounting frame. The two movable frames are symmetrically arranged. Two return springs are connected between each movable frame and the mounting frame. A connecting rod is rotatably connected to one side of each movable frame away from the supporting frame. A torsion spring is connected between the movable frame and the two connecting rods. A pressure plate is rotatably connected between the two connecting rods.

[0008] Furthermore, the movable frame is located on the top of the table frame, the movable frame is located below the soft brush roller, the movable frame is located on both sides of the wire mesh frame, and the movable frame is used to clamp and fix the wire mesh frame.

The guide groove ring is installed on the side of the soft brush roller close to the guide rod. The guide groove ring is provided with a guide groove. The guide rod and the guide groove of the guide groove ring are slidably matched.

[0010] The beneficial effects are:

[0011] The gears drive the rotating shaft and the soft-bristle brush roller to rotate, and the workers pour an appropriate amount of cleaning liquid into the wire mesh frame. The rotating soft-bristle brush roller quickly brushes the ink on the wire mesh frame, and the electric slider drives the straight slot frame to move in the opposite direction. During the reverse movement of the straight slot frame, the soft-bristle brush roller rotates in the opposite direction to brush the wire mesh frame for the second time. By using the soft-bristle brush roller to brush the wire mesh frame back and forth, the ink on the surface of the wire mesh frame can be more fully brushed, thereby improving the brushing efficiency.

[0012] The two connecting rods drive the two movable frames to move towards each other, so that the wire mesh frame is placed in the center, and the two movable frames then clamp and fix the wire mesh frame. When the soft-bristle brush roller brushes the wire mesh frame, the wire mesh frame is more stable and will not shift, thereby improving the stability of the wire mesh frame during brushing and facilitating the soft-bristle brush roller to brush the wire mesh frame more quickly.

[0013] The rotation of the guide groove ring drives the guide rod and the soft brush roller to reciprocate. By constantly adjusting the brushing position of the soft brush roller, the soft brush roller can fully brush the wire mesh frame, thereby increasing the brushing area. The soft brush roller can clean the ink contained in the mesh of the wire mesh frame. BRIEF DESCRIPTION OF THE DRAWINGS
