Description

Technical Field

[0001] This utility model relates to the field of light curing equipment technology, and in particular to a water-based UV plastic coating light curing equipment. Background Technology

[0002] Water-based UV plastic coating curing equipment is a device that uses ultraviolet (UV) light sources to emit ultraviolet rays of a specific wavelength, which are then irradiated onto the surface of plastic products coated with water-based UV coatings. This causes the photoinitiator in the coating to absorb the ultraviolet energy and generate free radicals or cations, thereby initiating a polymerization reaction in the resin and other components of the coating, which then quickly cures to form a coating film.

[0003] However, the light source of existing UV curing equipment requires a large amount of electrical energy to generate ultraviolet light, and the equipment overheats during prolonged operation, increasing energy consumption and operating costs. Furthermore, the curing effect of water-based UV coatings is greatly affected by ambient temperature. In high-temperature environments, the coating film is prone to slow drying and decreased adhesion; while in low-temperature environments, the fluidity of the coating deteriorates, affecting the smoothness of the coating film.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Reference Figure 1-4 The present invention provides a water-based UV plastic coating curing device: a water pump 8 is provided at the top of the inner wall of the device body 2, a curing lamp 5 is placed at the bottom of the water pump 8, a placement platform 7 is fixed at the bottom of the inner wall of the device body 2, and a heat dissipation mechanism is fixed at the top of the device body 2.

[0022] When the equipment is running, the staff places the items to be cured on the placement platform 7, and the curing lamp 5 cures them. During curing, the temperature of the curing lamp 5 rises, and at the same time, the water pump 8 on the curing lamp starts to circulate coolant, which is sent to the heat dissipation mechanism to cool it down, thereby maintaining the operating temperature of the equipment.

[0023] The heat dissipation mechanism includes a radiator 1 placed at the top of the outer side of the device body 2. Water pipes 6 are symmetrically connected to both sides of the radiator 1, and a water pump 8 is fixedly connected to the end of each water pipe 6. The radiator mechanism also includes a water tank 11 fixed inside the radiator 1. Water pipes 6 are fixedly connected to both ends of the water tank 11. One end of the radiator 1 has an air outlet 14, and the other end has a horizontal bar 12. Fans 9 are symmetrically installed on the horizontal bar 12. A small nut 13 is set in the center of each fan 9. A dustproof net 15 is set outside the fan 9. Fixing rods 17 are fixedly connected to both ends of the dustproof net 15. One end of the fixing rod 17 has a placement hole for a limiting rod 20 to engage. The fixing rod 17 is slidably connected to a groove 16, and a limiting mechanism is set at one end of the groove 16.

[0024] The heat dissipation mechanism starts to operate, and the coolant is sent into the water tank 11 by the water pump 8. The fan 9 on the crossbar 12 at one end of the radiator 1 starts to rotate to accelerate the airflow and remove the heat in the coolant. The accelerated air is discharged from the air outlet 14 at the other end of the radiator. The dustproof net 15 on the fixing rod 17 fixedly connected to the groove 16 prevents foreign objects from entering the fan 9, thereby accelerating the heat dissipation efficiency and ensuring that the equipment can operate normally for a long time.

[0025] The limiting mechanism includes a groove 16 with a movable groove 22 at one end, a limiting rod 20 that is slidably connected to the inner wall of the movable groove 22, a fixing block 24 at the other end of the movable groove 22 near the outer surface of the groove 16, a baffle 21 fixed on the side of the outer contour of the limiting rod 20 away from the fixing block 24, a return spring 19 that is sleeved on the fixing block 24 and connected to the limiting rod 20, the end of the return spring 19 away from the fixing block 24 contacting the baffle 21, and a threaded post 23 that is threadedly connected to the limiting rod 20, a rectangular block 18 that is fixedly connected to one end of the threaded post 23.

[0026] After the dustproof net 15 is installed, the limit rod 20 is fixed by the return spring 19 to prevent the dustproof net 15 from being misaligned due to external factors. When the dustproof net 15 needs to be replaced, the rectangular block 18 needs to be pulled to make the limit rod 20 retract in the moving groove 22 and disengage from the baffle 21 on the fixed block 24. If the rectangular block 18 is damaged, it can be replaced by separating it from the limit rod 20 through the threaded post 23.

[0027] Nuts 10 are provided at the four corners of the bottom of the curing lamp 5. The top of the body 2 of the water-based UV plastic coating curing equipment is provided with threaded holes for bolts 4 to be screwed in. A water pump 8 is placed on the top of the curing lamp 5, and the curing lamp 8 is placed at the bottom of the water pump 8 and uses the same set of fixing structure, thereby reducing the loss of heat dissipation efficiency caused by unnecessary structures.

[0028] To facilitate fixing the radiator 1, a groove is provided at the top of the outer side of the device body 2 for placing the radiator 1, and ventilation holes 3 are symmetrically arranged on both sides of the device body 2.

[0029] The top of the water-based UV plastic coating curing equipment body 2 is provided with a groove for placing the heat sink 1. In order to avoid the excess heat from affecting the product during equipment operation, ventilation holes 3 are symmetrically provided on both sides of the water-based UV plastic coating curing equipment body 2 to dissipate excess heat.

[0030] Working principle: When the equipment is running, the staff places the item to be cured on the placement platform 7, and the curing lamp 5 cures it. During curing, the temperature of the curing lamp 5 rises, and at the same time, the water pump on the curing lamp starts to circulate the coolant. The coolant is sent into the water tank 11 by the water pump 8. The fan 9 on the crossbar 12 at one end of the radiator 1 starts to rotate to accelerate the air flow and remove the heat in the coolant. The accelerated air is discharged from the air outlet 14 at the other end of the radiator.

[0031] The curing lamp 5 is placed at the lower end of the water pump 8 using the same fixing structure, thereby reducing the loss of heat dissipation efficiency caused by unnecessary structures. In order to facilitate the fixing of the heat sink 1, a groove for placing the heat sink 1 is opened at the top of the exterior of the water-based UV plastic coating curing equipment body 2. In order to avoid excess heat affecting the product during equipment operation, ventilation holes 3 are symmetrically arranged on both sides of the water-based UV plastic coating curing equipment body 2.

[0032] Furthermore, the dust filter and limiting mechanism at one end of the radiator fan can reduce the impact of external debris on the fan, prevent the loss of heat dissipation efficiency, and facilitate replacement, thus reducing the impact of external factors on the equipment during long-term operation.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
