Description

Technical Field

[0001] This invention relates to the field of printing press technology, specifically to a positioning printing device for a curved surface offset printing machine. Background Technology

[0002] Some plastic cups, bowls, and paper cups and bowls need to have patterns, production dates, etc. printed on specific positions on the conical surface to make the packaging more attractive and to introduce the product. Therefore, a printing machine is used. A printing machine is a machine that prints text and images. When printing on products, it is necessary to position them to prevent scrapping due to inaccurate positioning. Therefore, a curved surface offset printing machine positioning printing device is needed.

[0003] However, existing curved surface offset printing machines with positioning printing devices place the product to be printed directly on the drive roller during use. When positioning the product, guide rollers and auxiliary wheels are used to limit its position, but the positioning effect is poor and the position of the product cannot be accurately adjusted, which is not conducive to printing the product. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a positioning printing device for a curved offset printing machine, which solves the problems of poor positioning effect, inability to accurately adjust the position of the product, and difficulties in printing the product.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a positioning printing device for a curved offset printing machine, comprising an indexing box, an ignition unit on the upper part of the indexing box, a drying roller unit on the lower front side of the indexing box, a positioning wheel unit on the upper front side of the indexing box, a positioning cylinder fixedly connected to the left side of the positioning wheel unit, a positioning cylinder connecting block fixedly connected to the output end of the positioning cylinder, a floating joint unit fixedly connected to the left side of the positioning cylinder connecting block, and a fish-shaped connector fixedly connected to the left end of the floating joint unit. The fisheye connector has a positioning wheel rotatably connected to its rear side. A sensor switch bracket is fixedly connected to the upper left side of the indexing box. A sensor switch is fixedly connected to the upper part of the sensor switch bracket. A rotary air connector is provided on the left side of the positioning wheel. Multiple air pipes are fixedly connected to the outside of the rotary air connector. A clamping cylinder is fixedly connected to the end of the multiple air pipes away from the rotary air connector. A clamping block is fixedly connected to the output end of the clamping cylinder. A corona rubbing wheel is fixedly connected to the upper left side of the indexing box.

[0006] Preferably, each of the plurality of clamping blocks has a processing station on its exterior.

[0007] Preferably, the processing station includes a positioning station, a printing station, a drying station, a waste discharge station, a discharge station, and a feeding station.

[0008] Preferably, the ignition unit is installed on the upper part of the processing station.

[0009] Preferably, the ignition unit is fixedly connected to the upper front part of the support rod, and the support rod is fixedly connected to the upper part of the indexing box.

[0010] Preferably, the drying roller is fixedly connected to the upper part of the placement frame, and the placement frame is fixedly connected to the lower front part of the indexing box.

[0011] Preferably, the positioning wheel is fixedly connected to the upper part of the positioning frame, and the positioning frame is fixedly connected to the front side of the indexing box.

[0012] Preferably, the rotary air connector is rotatably connected to the left side of the indexing box.

[0013] Working principle: When the workpiece enters the feeding station through the feeding device, the indexing box rotates to the corona station. At this time, the corona roller assembly rotates, and the clamping cylinder and clamping block are disengaged from the mold. Then, the ignition assembly processes the workpiece surface. When it reaches the positioning station, the induction switch bracket and induction switch activate. Simultaneously, the fisheye connector, positioning wheel, positioning cylinder, positioning cylinder connecting block, positioning wheel, floating connector, clamping cylinder, and clamping block all begin to work, positioning the product printing points on the mold. After positioning, the fisheye connector and positioning... The wheel, positioning cylinder, positioning cylinder connecting block, positioning wheel, and floating joint are disengaged. The clamping cylinder and clamping block continue to work, preventing the mold from shifting during operation. When the machine continues to run and the mold reaches the printing station, the clamping cylinder and clamping block will disengage instantly, ensuring that the mold can rotate with the printing roller and transfer the pattern. The machine continues to run until the workpiece passes through the drying station to the discharge port and is discharged, thus completing this positioning printing. This achieves the effect of precise positioning printing, with high positioning accuracy, convenient adjustment and control, and easy operation.

[0014] This invention provides a positioning printing device for a curved surface offset printing machine. It has the following beneficial effects:

[0015] This invention involves the workpiece entering the feeding station via a feeding device. The indexing box rotates until it reaches the corona treatment station. During this time, the corona roller assembly rotates, and the clamping cylinder and clamping block are disengaged from the mold. Then, the ignition assembly processes the workpiece surface.
