Description

Technical Field

[0001] This application relates to the technical field of printing, and in particular to a control device for a UV ink jet coding machine. Background Art

[0002] The difference between UV printing and traditional printing lies in the different ink drying methods. In UV printing, a UV lamp irradiation desiccant is added to the ink. After printing, the paper with the ink passes through the irradiation of the UV lamp and forms a protective layer in a short time. Due to the better mechanical and chemical properties of ultraviolet curable ink, ultraviolet curable UV ink does not require solvents, has a fast drying speed, low energy consumption, the coding content is firm, the color is bright, water-resistant, and solvent-resistant, and is suitable for high-resolution and high-speed printing. In addition, UV inkjet can be printed on any non-absorbent, organic or inorganic material. In addition, UV printing also solves the problems of ink shedding and dropping of ordinary coding machines when exposed to strong acids and alkalis.

[0003] Currently, a Chinese patent with the publication number CN219467361U discloses an automated UV coding machine, which includes a support frame. A conveyor is installed inside the support frame. A coding machine is arranged above the conveyor. The coding machine is connected to an adjustment component. The adjustment component is installed outside the support frame. The lower end of the coding machine has a coding port. A cover plate is arranged outside the coding port. Guide blocks are provided on the inner wall of the cover plate. The guide blocks are slidably installed in guide grooves. The guide grooves are arranged on the outer surface of the coding port.

[0004] Regarding the above related technologies, the inventor believes that during the coding and printing process of the above automated UV coding machine, several products are transported by the conveyor. When the products are transported below the coding machine, the height and position of the coding machine are adjusted through the adjustment component to make it correspond to the specific position of the product and perform the coding and printing operation. However, this method will cause the position of the coding machine to be adjusted according to the specific position of the product on the conveyor before each coding, resulting in a decrease in coding efficiency. Summary of the Utility Model

[0005] In order to improve the efficiency and quality of UV coding operations, this application provides a control device for a UV ink jet coding machine.

[0006] The control device for a UV ink jet coding machine provided by this application adopts the following technical solutions:

[0007] A control device for a UV inkjet coding machine, comprising a conveyor belt, a detection component, an alignment component and a coding component. The detection component, the alignment component and the coding component are sequentially arranged on the conveyor belt along the conveying direction of the conveyor belt. The detection component includes a sliding block and a vision detector sensor. There are two sliding blocks arranged above the conveyor belt along the width direction of the conveyor belt, and one vision detection sensor is arranged below each sliding block. A driving member for driving the two sliding blocks to move along the width direction of the conveyor belt is arranged on the conveyor belt. The alignment component includes a push plate. There are two push plates vertically arranged on the conveyor belt along its length direction. A driving member for driving the two push plates to move along the width direction of the conveyor belt is arranged on the conveyor belt.

[0008] By adopting the above technical solution, two vision detection sensors simultaneously detect the position of the product. When the position of the product needs to be adjusted, the two push plates move towards each other or away from each other under the driving action of the driving member, and push the product to the middle of the conveyor belt. The product after position adjustment passes under the coding component for coding. Through the mutual cooperation of the conveyor belt, the detection component, the alignment component and the coding component, the position detection and alignment adjustment of the product are realized, and the effect of improving the efficiency and quality of UV coding operation is achieved.

A plurality of dust blowing nozzles are communicated and arranged on one side of the dust blowing pipe close to the conveyor belt. Two ends of the first connecting pipe are respectively communicated and arranged with the dust blowing pipe and the dust blowing fan.

[0010] By adopting the above technical solution, when the dust blowing fan is started, the air flow is blown onto the product below through a plurality of dust blowing nozzles, and the floating dust on the surface of the product is blown off, which helps to improve the quality of subsequent coding operation.

A dust suction nozzle is communicated and arranged on one side of the dust suction pipe close to the conveyor belt. A second connecting pipe is communicated and arranged on the dust suction pipe. One end of the second connecting pipe away from the dust suction pipe is communicated and arranged with a dust storage box.

[0012] By adopting the above technical solution, when the dust suction pump is started, the floating dust on the conveyor belt enters the dust storage box through the dust suction nozzle and the dust suction pipe for temporary storage, which helps to reduce the floating dust content on the conveyor belt and helps to improve the coding quality of the product.

[0013] Optionally, the detection component further includes an adjusting screw rod and an adjusting guide rod. Two threaded segments with opposite helix directions are provided at both ends of the adjusting screw rod. The two sliding blocks correspond to and are threadedly connected to the two threaded segments on the adjusting screw rod.

The adjusting screw rod is parallel to the adjusting guide rod and is arranged along the length direction of the conveyor belt. A driving source for driving the adjusting screw rod to rotate is provided on the conveyor belt.

[0014] By adopting the above technical solution, the driving source drives the adjusting screw rod to rotate. Under the driving of the adjusting screw rod and the guiding action of the adjusting guide rod, the two sliding blocks move towards each other or away from each other, realizing the synchronous position adjustment of the two sliding blocks.

[0015] Optionally, scale lines are arranged along the length direction on the adjusting guide rod.

The inkjet printer is arranged on the bottom surface of the rotating circular plate. A driving member for driving the rotating circular plate to rotate is arranged on the mounting plate.

[0018] By adopting the above technical solution, when the product moves below the conveyor belt, the rotating circular plate rotates to a proper angle under the driving of the driving member, so that the position and direction of the inkjet printer correspond to the position where the product needs to be inkjet-printed, expanding the application range of the device.

[0019] Optionally, a rotating rod is arranged at the top end of the inkjet printer. The top end of the rotating rod is rotatably connected with the bottom surface of the rotating circular plate. A rotating cylinder is rotatably arranged on the bottom surface of the rotating circular plate. The output shaft of the rotating cylinder is rotatably connected with the inkjet printer.

[0020] By adopting the above technical solution, when the rotating cylinder starts, it drives the inkjet printer to rotate to a proper angle, so that the angle of the inkjet printer can correspond to the angle of the product, expanding the use range of the device.

[0021] Optionally, gaskets are arranged on one side of the two push plates close to each other.

[0022] By adopting the above technical solution, the arrangement of the gaskets reduces the possibility of damage to the product during the alignment process.
