Description

Technical Field

[0001] The utility model belongs to the technical field of glass processing, and particularly relates to a screen printing glass conveying structure. Background Art

[0002] Screen-printed glass is a product with patterns and colors printed on the glass surface through screen printing technology, which has the characteristics of rich decoration, good durability, and strong customization. Its manufacturing process includes steps such as designing patterns, making screen plates, preparing glass, printing ink, drying and curing, and quality inspection. It is widely used in fields such as architectural decoration, household items, handicrafts, and advertising.

[0003] During the screen printing process, it is necessary to convey and print the glass. However, most of the existing conveying devices directly place the glass on the conveyor belt and send it to the printing station for direct printing. There is no positioning mechanism, and the stress and stay process are all carried out on the conveyor belt, resulting in the conveyor belt being deformed and stressed for a long time, making the conveyor belt more prone to damage. In addition, during the printing process, other glasses on the conveyor belt may stop, slowing down the feeding and discharging speeds. Using multiple conveyor belts will cause the glass to be prone to skew during transfer, and it needs to be corrected, which is a waste of time. Summary of the Utility Model

[0004] The technical problem to be solved by the utility model is that most of the existing screen printing conveying mechanisms directly place the glass on the conveyor belt and send it to the printing station for direct printing, resulting in the conveyor belt being deformed and stressed for a long time, making the conveyor belt more prone to damage, and the transfer through multiple conveyor belts will cause skew and need to be corrected, wasting time.

[0005] To solve the above technical problems, the technical solution provided by the present utility model is a screen printing glass conveying structure, including a feeding support and a printing table. The feeding support is located on one side of the printing table. Above the feeding support, a plurality of first conveying rollers are rotatably connected. One end of each of the plurality of first conveying rollers is provided with a first toothed disc. The toothed discs are connected by a first chain. On both sides above the feeding support, positioning frames are provided. One side of the positioning frame is connected with a guiding plate through a plurality of studs. The plurality of studs are fixed on both sides of the positioning frame by nuts. A working groove is provided on the printing table. Positioning grooves are provided on both sides perpendicular to the feeding support of the working groove. A positioning frame is provided inside the positioning groove. An elevating frame is provided in the middle of the working groove between the two positioning grooves. A plurality of second conveying rollers are provided on the elevating frame. One end of each of the plurality of second conveying rollers is provided with a second toothed disc. The toothed discs are connected by a second chain. A first elevating cylinder is provided at the bottom of the elevating frame. A guiding slide rail is provided outside one side of the positioning groove. A moving support is slidably connected inside the guiding slide rail. A limiting frame is slidably connected above the moving support. One side of the moving support is fixedly connected with one end of the limiting frame through a second elevating cylinder.

[0006] Preferably, the middle position of the feeding support and the middle position of the working groove are in the same vertical plane.

[0007] Preferably, the shapes of the first conveying roller and the second conveying roller match. Both the first conveying roller and the second conveying roller are composed of a rotating shaft and a plurality of transmission wheels. The plurality of transmission wheels are equidistantly arranged on the rotating shaft. One end of one of the first conveying roller and the second conveying roller is connected with a first motor.

[0008] Preferably, a limiting groove is provided in the middle of the outer side of the plurality of transmission wheels, and a rubber ring is wrapped around the limiting groove.

[0009] Preferably, the two guiding plates are arranged parallel to the direction of the feeding support. The bottom of the guiding plate is above the rotating shaft, and the height of the guiding plate is greater than the radius of the plurality of transmission wheels.

[0010] Preferably, the limiting frame is provided with corresponding "mountain"-shaped limiting plates at the plurality of second conveying rollers, and the bottom of the limiting plate is located at the position between the plurality of transmission wheels.

[0011] Preferably, the positioning frame is made of either rubber or plastic as a whole.

[0012] Preferably, a threaded rod is provided inside the guiding slide rail. The bottom of the moving support is in threaded fit with the threaded rod. The threaded rod is connected with a second motor through a synchronous belt on the side close to the feeding support.

[0013] Preferably, the limiting frame is provided with corresponding guiding sliding grooves at the moving support, and the limiting frame is provided with corresponding guiding sliders at the guiding sliding grooves. An extension plate is arranged on one side of the limiting frame, and the second lifting cylinder is arranged on the extension plate and is parallel to the limiting frame.

[0014] The advantages of the present utility model compared with the prior art are as follows:

[0015] 1. By arranging a plurality of conveying rollers on the feeding support and the printing table, and arranging rubber rings on the conveying rollers to increase the friction force, this conveying mechanism can prevent slipping during the glass conveying process, and the moving direction of the glass is limited by a plurality of synchronously rotating transmission wheels and guiding plates to prevent skewing during the moving process.

[0016] 2. The conveying mechanism is provided with a lifting frame at the printing table, so that while receiving and sending out the glass, the glass can be sent to the positioning frame for positioning printing. The positioning frame bears the deformation generated by the extrusion during printing, reduces the stress on the conveying rollers, and at the same time locates the printing position through the limiting frame on one side.
