Description

Technical Field

[0001] This utility model relates to the field of flexible resin plate processing technology, and in particular to a resin plate exposure machine with a circulating liquid cooling device. Background Technology

[0002] Flexible printing plates are mostly used in self-adhesive printing. When exposing the plate, a negative film is produced. The printing plate is made by exposing and washing with ultraviolet light. The prototype can be either a liquid plate or a solid plate. The printing plate is made according to the exposure principle.

[0003] Patent document CN222561909U discloses a flexible resin substrate exposure machine, including an exposure machine body, a fixing module, a smoothing module, and a pushing module. The pushing module includes a linear guide rail, a ball bearing slider, and a rectangular frame. The smoothing module includes two bidirectional lead screws, each with two sections of threads in opposite directions at its ends. When the flexible resin substrate needs to be exposed, it is placed at the bottom of the rectangular frame. The fixing module secures the substrate to the center of both sides using two star-head bolts. The smoothing module moves two smoothing rollers away from each other, smoothing out wrinkles on the substrate. The pushing module guides the substrate into the exposure machine body for exposure.

[0004] However, when exposing resin plates, the exposure module of this exposure machine reaches a high temperature during prolonged operation. Conventional air cooling is inefficient, easily leading to a reduction in the lifespan of the exposure module. Furthermore, dust can enter the exposure machine body during air cooling, affecting the exposure effect on the resin plates. Therefore, it is necessary to improve this structure to overcome these shortcomings. Utility Model Content

[0064] Example 2

[0065] like Figure 1-8As shown, the difference between this embodiment and Embodiment 1 is that, in this embodiment, the water-cooling assembly includes a chiller 610, a water tank 620, a water pump 630, a cooling plate 640, a heat dissipation copper pipe 650, an inlet hose 660, and an outlet hose 670.

One side of the water tank is connected to the chiller via a pipe, and the water tank stores cooling water. The water pump is connected to the water tank via a pipe, and one side of the water pump has an outlet. The cooling plate is located inside the protective cover and one side of the cooling plate is connected to the exposure lamp assembly. The cooling plate has a meandering heat dissipation groove 641, which is used to dissipate heat. The cooling plate dissipates heat from the exposure lamp assembly. A copper heat dissipation pipe is installed in a heat dissipation groove within the cooling plate. The shape of the copper heat dissipation pipe matches the groove. Coolant is contained within the copper heat dissipation pipe. One side of the copper heat dissipation pipe has an inlet, and the other side has an outlet. One side of the inlet hose is connected to the inlet of the copper heat dissipation pipe, and the other side is connected to a water pump. One side of the outlet hose is connected to the outlet of the copper heat dissipation pipe, and the other side is connected to the inlet of the water chiller. It is worth noting that when the ambient temperature is low, conventional air cooling is sufficient to cool the exposure lamp assembly. The water cooling system is only required when the room temperature is high.

[0066] In this embodiment, a set of suction holes 103 are provided on the processing table. The suction holes are connected to a negative pressure fan (not shown in the figure). The negative pressure fan is existing technology and will not be described in detail here.

[0067] In this embodiment, guide blocks 121 are provided on both sides of the fixed bracket. The guide blocks are located on the outside of the moving rack and limit the movement of the moving rack.

[0068] The working principle of this utility model:

[0069] When processing the resin board, the resin board is placed on the processing table. The film is pulled out from the discharge port of the storage box and then covered on the surface of the resin board. After the film is pulled under the film pressure plate, the rotary screw is rotated. The rotary screw drives the film pressure plate downward through the threaded engagement, thereby fixing the film. Then, air is sucked in through the suction port to fix the film, thus fixing the resin board. Then, the electric telescopic rod drives the lifting column downward. As the lifting column moves downward, it also moves the protective cover downward. As the protective cover moves downward, the rack moves. Engaging with the rotating gears, the protective cover is guided. Simultaneously, the exposure lamp assembly exposes the resin plate. At this time, the intake and exhaust fans operate to expel the hot air generated by the exposure lamp assembly. When the temperature becomes too high, the water pump draws out the coolant from the water tank and delivers it to the heat dissipation copper pipe through the inlet hose. The heat dissipation copper pipe exchanges heat with the cooling plate, which in turn exchanges heat with the exposure lamp plate, thereby cooling the exposure lamp plate. The coolant, having completed heat exchange, flows back to the chiller through the outlet hose. The chiller cools the coolant and then delivers it back to the water tank, thus completing the circulation.
