Description
Technical Field
[0001] This utility model relates to the field of photocurable ink technology, specifically a photocuring machine for photocurable inks. Background Technology
[0002] Photocuring technology is a technique that uses ultraviolet radiation to cure liquid resins or polymers into a solid state in a short time. It can also use ultraviolet, visible, and near-infrared light sources to rapidly cure photosensitive materials. It has advantages such as high efficiency and environmental friendliness, and is widely used in coatings, inks, adhesives and other fields.
[0003] In existing UV curing machines used for UV-curing inks, the illumination range of the light cannot be adjusted. This results in the light coverage area being much larger than the actual width of the material when performing UV curing on narrow materials, thus increasing the power consumption of the equipment. Furthermore, existing devices are not convenient for fine-tuning the illumination range. Therefore, we propose a UV curing machine for UV-curing inks. Utility Model Content
[0004] The technical problem this invention aims to solve is to overcome existing defects and provide a UV curing machine for UV-curing inks. The irradiation device consists of multiple lamp holders arranged horizontally, and the width of the illuminated area can be controlled by a controller on the upper side. This allows for adjustment of the number of lamps turned on based on the width of the conveyed material, achieving energy savings. Furthermore, a ball screw can drive the mounting frame to rise and fall, thereby fine-tuning the irradiation range. A reliable conveying adjustment unit is also included, capable of centering and clamping the conveyed material to ensure it passes through the lower middle part of the illuminated area. Additionally, the height of the ink brush is adjustable to improve its adaptability to materials of different thicknesses, effectively solving the problems in the prior art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a photocuring machine for photocurable inks, comprising a side mounting bracket, a light control unit, and a transport and adjustment unit;
[0006] Side mounting bracket: consists of two parallel plates arranged longitudinally on the left and right sides. The top frame is an inverted U-shaped structure, and the lower ends of the left and right sides are respectively fixedly connected to the upper middle part of the two side mounting brackets. Each side mounting bracket has a support column fixedly connected to its lower end, and a square foot is fixedly connected to the lower side of the support column.

The nut of the ball screw is embedded and fixedly connected to the inner side of the end of the mounting bracket. A row of long rod-shaped lamp holders is bolted to the lower side of the mounting bracket. Light-emitting devices are mounted on the lower side of each lamp holder. A sub-controller is mounted on the upper side of each lamp holder. A main controller is mounted at the center of the top of the mounting bracket. Each sub-controller is electrically connected to the main controller via connecting wires.
[0008] Transport adjustment unit: installed on the upper front end of the side mounting bracket.

In addition, the number of lamps turned on can be adjusted according to the width of the conveyed material to achieve energy saving. Furthermore, the ball screw can drive the mounting frame to lift and lower, thereby fine-tuning the range of light illumination. The main controller is used to start and stop the operation of each sub-controller.
[0010] Furthermore, the illumination control unit also includes a belt conveyor, a touch panel, lamp bars, and reflectors. A belt conveyor is installed between the left and right side mounting brackets, and a touch panel is installed on the right side of the top frame.

A hydraulic cylinder is installed inside the outer U-shaped housing, with its extension end passing through the inner U-shaped housing and a clamping plate fixedly connected to its end. The front end of the clamping plate is bent outwards, and a distance sensor is embedded in the straight section facing inwards. The combination frame is used to mount the hydraulic cylinder, which drives the folded clamping plate towards the center, thereby centering the conveyed material on the conveyor belt surface. The distance sensor detects the distance between the two clamping plates and displays it via a touch panel, facilitating operator adjustment of the width between the clamping plates.

Each solenoid valve has a connecting pipe fixedly connected to its upper end, with the lower end of the connecting pipe facing inward and communicating with the clamping groove of the end bracket. An indicator light is installed on the front of each solenoid valve, displaying both red and green lights. The connecting pipe is used to connect a flexible hose to an external ink source. The delivered ink passes through the clamping groove and then wets the ink brush. The width of the ink application by the brush can be controlled by the number of solenoid valves opened. The indicator lights show the open / closed status of the solenoid valves; the indicator light is red when the solenoid valve is closed and green when it is lit.
[0014] Furthermore, the transport adjustment unit also includes a through slot. A vertical through slot is provided on the middle side of the U-shaped end bracket.
