Description

Technical Field

[0001] This utility model relates to the field of screen printing technology, and in particular to a four-sided screen printing machine for ceramic plates. Background Technology

[0002] Ceramic slabs are plate-shaped ceramic products made primarily from inorganic non-metallic materials (such as clay, quartz, feldspar, etc.) through processes such as molding, drying, and high-temperature sintering. During the production and processing of ceramic slabs, to improve their aesthetics and workability, screen printing is required on the surface. For the sides of the ceramic slab, using a four-sided screen printing machine to process all four sides in one pass improves processing efficiency and ensures processing precision.

[0003] Existing four-sided screen printing machines operate by placing a ceramic plate on a rotating turntable with one side of the plate facing the screen. After applying screen printing ink to the screen, it moves to contact the side of the ceramic plate, and the screen printing begins. Once printing is complete, the turntable rotates 90 degrees to print the next side, continuing until all four sides are printed. However, existing four-sided screen printing machines use pressure plates to hold the ceramic plate in place. After each side is printed, the pressure plate must be moved upwards to loosen the clamping, and then the plate must be rotated and clamped again. This repeated clamping and loosening process is time-consuming and can easily cause the ceramic plate to shift, affecting subsequent printing results. Adjustments are needed to ensure printing accuracy, making the entire screen printing process time-consuming and labor-intensive. Utility Model Content

[0004] The main purpose of this utility model is to provide a four-sided screen printing machine for ceramic plates, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A four-sided screen printing machine for ceramic plates includes a base, a rotating seat mounted on the base, a placement plate fixed on the rotating seat, a mounting frame on the base, a curing lamp fixed on the mounting frame, a fixed seat on the base, a movable seat mounted on the fixed seat, a fixed frame on the movable seat, a material pressing structure on the base, a screen printing plate mounted on the fixed frame, a slide on the movable seat, and a scraper connected to the slide.

[0007] Preferably, the pressing structure includes a bracket, a pressing cylinder, a telescopic shaft, a connecting rod, and a limiting plate. The bracket is fixed on the base, the pressing cylinder is connected to the telescopic shaft and is mounted on the bracket, and the connecting rod is located at the lower end of the telescopic shaft and is fixedly connected to the limiting plate.

[0008] Preferably, the pressing structure further includes a connecting sleeve, a bearing, a follower rod, a pressure plate, and a connecting screw. The bearing is mounted on the connecting sleeve and connected to the lower end of the connecting rod. The four follower rods are mounted in a circular array on the connecting sleeve. The pressure plate and the connecting screw are fixedly connected, and the connecting screw is threaded to the end of the follower rod.

[0009] Preferably, the base has a rotary motor inside, and the rotary motor is connected to the rotary seat, and the lower end of the base has a support leg.

[0018] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0019] like Figures 1-5 As shown, a four-sided screen printing machine for ceramic plates includes a base 1, a rotating seat 2 mounted on the base 1, a placement plate 3 fixed on the rotating seat 2, a mounting frame 5 on the base 1, a curing lamp 4 fixed on the mounting frame 5, a fixed seat 7 on the base 1, a movable seat 8 mounted on the fixed seat 7, a fixed frame 11 on the movable seat 8, a pressing structure 6 on the base 1, a screen printing plate 12 mounted on the fixed frame 11, a slide 13 on the movable seat 8, and a scraper 14 connected to the slide 13. A rotary motor is installed inside the base 1 and connected to the rotating seat 2. Support legs 16 are provided at the lower end of the base 1.

[0020] The fixed base 7 is equipped with a first servo motor 9, and the interior of the fixed base 7 is equipped with a first lead screw connected to the movable base 8. The end of the movable base 8 is equipped with a second servo motor 10, and the interior of the movable base 8 is equipped with a second lead screw connected to the slide 13. The slide 13 is equipped with a control cylinder 15, and the extension rod of the control cylinder 15 is connected to the scraper 14.

[0021] When using a screen printing machine to print on all four sides of a ceramic plate, the screen printing machine is placed on the support 16. The support 16 is adjusted to ensure the levelness of the screen printing machine. The ceramic plate is placed in the center of the placement plate 3, ensuring that one side of the ceramic plate is facing the screen 12. The pressing structure 6 is activated to press and fix the ceramic plate, and then the screen printing work is carried out. During the screen printing process, screen printing ink is applied to the screen 12. The first servo motor 9 on the fixed base 7 is started. The first servo motor 9 drives the first lead screw, thereby driving the movable base 8 to move on the fixed base 7. The fixed frame 11, screen 12, slide 13, squeegee 14 and control cylinder 15 move together until the screen 12 contacts the side of the ceramic plate. Then the control cylinder 15 operates so that the squeegee 14 presses against the mesh surface in the screen 12, and the mesh surface is in close contact with the side of the ceramic plate. The second servo motor 10 is started, and the second lead screw drives the slide 13 to move back and forth on the movable base 8, thereby causing the squeegee 14 to scrape the screen printing ink onto the ceramic plate, thus completing the screen printing work.

[0022] After the initial screen printing is complete, the first servo motor 9 starts, moving the movable seat 8 away from the ceramic plate. Then, the internal rotary motor of the base 1 starts, causing the rotating seat 2 to rotate 90 degrees along with the placement plate 3 and the ceramic plate. During this process, the pressing part of the pressing structure 6 rotates along with it, without affecting the pressing effect. After the ceramic plate rotates 90 degrees, the side screen printing is performed again following the above process. The screen-printed side faces the curing lamp 4, which generates ultraviolet light that irradiates the screen printing ink, achieving a curing effect and allowing the ink to dry quickly. After screen printing on all four sides of the ceramic plate is completed according to the above process, the pressing structure 6 no longer presses the ceramic plate. The ceramic plate can then be replaced, and screen printing can continue.

[0023] According to the above implementation scheme, the pressing structure 6 includes a bracket 601, a pressing cylinder 602, a telescopic shaft 603, a connecting rod 604, and a limiting plate 605. The bracket 601 is fixed on the base 1, the pressing cylinder 602 is connected to the telescopic shaft 603 and is mounted on the bracket 601, and the connecting rod 604 is located at the lower end of the telescopic shaft 603 and is fixedly connected to the limiting plate 605.

[0024] The pressing structure 6 also includes a connecting sleeve 606, a bearing 607, a follower rod 608, a pressure plate 609, and a connecting screw 610. The bearing 607 is mounted on the connecting sleeve 606 and is connected to the lower end of the connecting rod 604. The four follower rods 608 are mounted in a ring array on the connecting sleeve 606. The pressure plate 609 and the connecting screw 610 are fixedly connected, and the connecting screw 610 is threaded to the end of the follower rod 608.

[0025] When using the pressing structure 6, after activating the pressing cylinder 602 on the bracket 601, the telescopic shaft 603 lowers the connecting rod 604, and the connecting sleeve 606, follower rod 608, and pressing plate 609 descend together until the pressing plate 609 presses onto the ceramic plate, thus completing the fixing of the ceramic plate. After one side of the ceramic plate is screen-printed, the placement plate 3 rotates the ceramic plate 90 degrees. During the rotation, the pressing plate 609, follower rod 608, and connecting sleeve 606 rotate at the lower end of the connecting rod 604 via the bearing 607. This ensures that the pressing force remains unchanged while not affecting the normal rotation of the ceramic plate. After the rotation is complete, the screen-printing process on the side of the ceramic plate can continue. When needed, the position of the pressing plate 609 relative to the follower rod 608 can be adjusted using the connecting screw 610, providing high flexibility and adaptability.

[0026] It should be noted that, through the set pressing structure 6, a connecting rod 604 is set at the lower end of the telescopic shaft 603. The connecting rod 604 is installed together with the connecting sleeve 606 through the bearing 607. It works in conjunction with the follower rod 608, the pressure plate 609 and the connecting screw 610 to press and fix the ceramic plate normally. At the same time, when the placement plate 3 rotates with the ceramic plate, the connecting sleeve 606, the follower rod 608, the pressure plate 609 and other structures can rotate through the bearing 607 to complete the angle adjustment of the ceramic plate without affecting the pressing effect. There is no need to press again, which can ensure the placement accuracy of the ceramic plate and ensure the effect of subsequent screen printing. The pressure plate 609 can be height adjusted at the end of the follower rod 608 through the connecting screw 610, which improves the flexibility and adaptability of use. The follower rod 608 and the pressure plate 609 are distributed in a ring array on the connecting sleeve 606 to ensure the uniform force on the ceramic plate and ensure the pressing effect.
