Description

Technical Field

[0001] This utility model relates to the field of glass production equipment, and in particular to a screen printing device for producing LOW-E glass. Background Technology

[0002] Screen printing, also known as stencil printing, involves creating small holes in the printed areas while keeping the non-printed areas opaque. Screen printing produces thick inks and vibrant colors, and its operation is simple, primarily controlled by the size of the holes on the printing plate.

[0003] Screen printing consists of five main elements: the screen printing plate, the squeegee, the ink, the printing table, and the substrate. It utilizes the basic principle that ink can pass through the mesh openings of the screen printing plate in the image areas, while ink cannot pass through the openings in the non-image areas. During printing, ink is poured into one end of the screen printing plate, and the squeegee applies pressure to the ink areas while moving at a constant speed towards the other end. As it moves, the ink is forced through the mesh openings in the image areas onto the substrate.

[0004] Patent application number 202421344637.8 discloses a screen printing device for processing LOW-E glass. This device uses a clamping mechanism where two clamping plates move towards each other to clamp and fix the glass in the middle. Simultaneously, the glass presses against the bottom end of a curved plate, causing the curved plate to rotate around a rotating rod. The curved plate then drives the end rubber plate to rotate towards the glass, pressing and fixing the top of the glass, making the clamping more stable. However, this glass clamping device cannot be adjusted according to the thickness of the glass, making it unsuitable for thicker glass. Therefore, developing a novel screen printing device for LOW-E glass production is a problem urgently needing to be solved by those skilled in the art. Utility Model Content

[0005] The purpose of this invention is to provide a screen printing device for producing LOW-E glass, which solves the problem that the glass clamping device of existing screen printing devices cannot be adjusted according to the thickness of the glass, and is therefore unsuitable for thicker glass.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: This utility model discloses a screen printing device for producing LOW-E glass, comprising a frame, a screen printing mechanism body, a pressing mechanism, and a clamping mechanism. The frame includes a base plate and a support frame. The support frame is fixedly mounted on the upper end of the base plate. The screen printing mechanism body, which mates with the upper surface of the glass plate, is mounted on the support frame. A pressing mechanism that mates with the glass plate is mounted on the left end of the base plate, and a clamping mechanism that mates with the glass plate is mounted on the right end of the base plate. A first lead screw and a guide rod that mate with a first drive block on the back of a U-shaped frame are disposed between the base plate and the support frame. An L-shaped pressure plate and a trigger plate that mate with the glass plate are disposed on the rotating cylinder of the U-shaped frame.

[0007] Furthermore, the rotating cylinder is hinged within the U-shaped frame, the L-shaped pressure plate engages with the upper surface of the glass plate, and the trigger plate engages with the left end face of the glass plate.

[0008] Furthermore, a reset spring is provided between the trigger plate and the U-shaped frame.

[0009] Furthermore, the end of the trigger plate is provided with a guide wheel that cooperates with the glass plate.

[0010] Furthermore, the top of the support frame is provided with a first drive motor for driving the first lead screw; the first lead screw is threadedly engaged with the first drive block, and the guide rod is slidably engaged with the first drive block.

[0011] Furthermore, the screen printing mechanism body is fixedly mounted on the output end of the cylinder, and the cylinder is mounted in the slide groove of the support frame that can move left and right through a sliding block; the sliding block is provided with a top wire that cooperates with the support frame.

[0012] Furthermore, the clamping mechanism includes a push plate, a second drive block, a second lead screw, and a support plate. Two support plates are provided at the bottom end of the base plate, and a second lead screw is rotatably arranged between the two support plates. A second drive block that is threadedly engaged with the second lead screw is provided at the lower end of the push plate, and a second drive motor for driving the second lead screw is provided on the support plate.

[0013] Furthermore, a support leg is provided at the lower end of the base plate, and the length of the support leg is greater than the length of the support plate.

[0014] Compared with the prior art, the beneficial technical effects of this utility model are as follows: The clamping mechanism of this screen printing device for producing LOW-E glass can be height-adjusted via a first drive block and a first lead screw, thus enabling the use of glass of considerable thickness. The screen printing mechanism itself can move left and right within a groove in the support frame via a sliding block, making its use more flexible. In summary, this screen printing device for producing LOW-E glass is simple in structure, practical in function, and ingeniously designed, effectively solving the problem that existing screen printing devices cannot adjust their glass clamping mechanism according to glass thickness, making them unsuitable for thicker glass.
