Description

Technical Field

[0001] This utility model relates to the field of spraying device technology, and in particular to a spraying device for anti-fog coating of goggles. Background Technology

[0002] As a protective device used to protect the eyes from external damage, goggles are widely used in medical, industrial, and sports fields. They can effectively block dust, droplets, chemicals, and other substances from invading the eyes, ensuring the user's eye safety and clear vision. However, in actual use, goggle lenses are prone to fogging due to temperature differences between the inside and outside, resulting in blurred vision, seriously affecting the effectiveness of use, and even causing safety hazards. Therefore, it is necessary to spray an anti-fog coating on the surface of the goggle lenses. Through the hydrophilic or hydrophobic properties of the coating, water vapor is inhibited from condensing into fog, ensuring that the lenses always remain clear.

[0003] However, this anti-fog coating spraying device for goggles has the following disadvantages:

[0004] (1) Existing devices mostly use conveyor belts to transport goggles for spraying. Since the goggles need to be placed with one side facing up, only the side facing up can be sprayed. After one side is sprayed, manual or additional equipment is required to flip the goggles over and send them back into the conveyor to spray the other side. It is impossible to achieve simultaneous spraying on both sides, which is cumbersome and greatly reduces the spraying efficiency.

[0005] (2) During the spraying process, a large amount of spray liquid that does not adhere to the goggles will be generated in the spray box. However, the existing device lacks a special spray liquid collection structure, so the excess spray liquid cannot be effectively recycled, resulting in the waste of raw materials. Utility Model Content

[0006] (a) Technical problems to be solved

[0007] The technical problem solved by the utility model is to provide a goggle anti-fog coating spraying device that is highly practical, easy to operate, and has a simple structure. It solves the problems mentioned in the background art, such as the inability to achieve simultaneous double-sided spraying and the lack of a dedicated spray liquid collection structure in existing devices.

[0008] (II) Technical Solution

[0009] To achieve the above objectives, this utility model is implemented through the following technical solution: a goggle anti-fog coating spraying device, including a spraying box, a collection box fixedly connected to the bottom of the spraying box, a rotating roller rotatably installed inside the spraying box, a spraying component for spraying both sides of the goggles being provided on the outer periphery of the rotating roller, and a collection component for recycling the spray liquid being provided inside the collection box.

[0010] The spraying assembly includes two supports fixedly connected at equal intervals to the outer periphery of the rotating roller. A rotating rod is rotatably installed between the two supports. Square frames are fixedly connected to both sides of the rotating rod. A bidirectional lead screw is threaded into the interior of one of the square frames, and a limit rod is fixedly connected into the interior of the other square frame. Support plates are threaded into both ends of the outer periphery of the bidirectional lead screw. Rubber pads are fixedly connected to the opposite sides of the two support plates. Empty discs are fixedly installed on both sides of the inner wall of the spraying box. Several spray nozzles are fixedly connected to the opposite sides of the two empty discs.

[0011] The collection assembly includes two water pumps fixedly installed inside the collection box. Connecting pipes are fixedly connected to both sides of the spray box. The output ends of the water pumps are fixedly connected to the corresponding connecting pipes. The ends of the connecting pipes away from the water pumps extend into the interior of the corresponding empty trays. A drain outlet is provided between the spray box and the collection box.

[0012] Optionally, the support plates are all slidably connected to the outer periphery of the limiting rod, and the inside of the rubber pad is provided with a convex surface that fits against the outer wall of the goggles to ensure that the clamping is firm and does not damage the goggles.

[0013] Optionally, a servo motor is fixedly installed on the rear side of the spray box. The output shaft of the servo motor extends into the interior of the spray box and is fixedly connected to the rotation shaft of the rotating roller. The rotation of the output shaft of the servo motor drives the rotating roller to rotate, thereby realizing the transmission of power.

[0014] Optionally, a water level sensor is fixedly installed on the inner wall of the collection box, and three alarms are fixedly installed on the top of the spray box, which can monitor the water level of the spray liquid in the collection box in real time.

[0015] Optionally, a controller is provided on the outside of the spray box, a viewing window is provided on the outer periphery of the spray box, and a water inlet is fixedly connected to the outside of the collection box, through which spray liquid can be injected into the collection box.

[0016] Optionally, the spray box is hinged with doors on both sides, and the bottom of the inner wall of the spray box is provided with a slope for drainage, so as to facilitate the rapid discharge of the spray liquid in the spray box.

[0017] (III) Beneficial Effects

[0018] This utility model provides a device for spraying anti-fog coating on goggles, which has the following beneficial effects:

[0019] 1. This anti-fog coating spraying device for goggles, through the setting of the spraying components, can drive the support plates at both ends of its outer perimeter to move. Due to the constraint of the movement direction of the support plates by the limiting rod, the two support plates can move stably in opposite directions, thereby achieving the purpose of clamping the goggles. During the rotation of the roller driven by the servo motor, due to the gravity of the goggles themselves, the goggles are always in a perpendicular state to the ground, thus ensuring that both sides of the goggles are always in a stable ready-to-be-sprayed state during the spraying process. At the same time, the empty trays and several nozzles on both sides of the inner wall of the spraying box can simultaneously spray the vertically positioned goggles from both sides, eliminating the need for manual or additional equipment to flip them over. This eliminates the need for secondary operation after single-sided spraying on the traditional conveyor belt, greatly shortening the spraying process and significantly improving spraying efficiency and uniformity.

[0020] 2. This anti-fog coating spraying device for goggles, through the setting of the collection component, can transport the spray liquid in the tank to the empty tray through the connecting pipe, and then reuse it for spraying through the nozzle. The spray liquid that does not adhere to the goggles will flow back to the collection tank, forming a spray liquid recycling system. This structure effectively recovers the spray liquid that does not adhere to the goggles during the spraying process, avoids the waste of raw materials, reduces production costs, and reduces the environmental impact of random discharge of spray liquid, thus combining economic efficiency and environmental protection.

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0027] Please see Figures 1 to 4 This utility model provides a technical solution: a goggle anti-fog coating spraying device, including a spraying box 1, a collection box 2 fixedly connected to the bottom of the spraying box 1, a rotating roller 3 rotatably installed inside the spraying box 1, a spraying component for spraying both sides of the goggles is provided on the outer periphery of the rotating roller 3, and a collection component for recycling the spray liquid is provided inside the collection box 2.

[0028] The spraying assembly includes two supports 11 equidistantly fixed to the outer periphery of the rotating roller 3. A rotating rod 13 is rotatably mounted between the two supports 11. Square frames 14 are fixedly connected to both sides of the rotating rod 13. One square frame 14 is internally threaded with a bidirectional lead screw 16, and the other square frame 14 is internally fixedly connected with a limit rod 15. Support plates 17 are threaded to both ends of the outer periphery of the bidirectional lead screw 16. Rubber pads 18 are fixedly connected to the opposite sides of the two support plates 17. Empty discs 9 are fixedly mounted on both sides of the inner wall of the spray box 1. Several nozzles 10 are fixedly connected to the opposite sides of the two empty discs 9. When the bidirectional lead screw 16 rotates, it can drive the support plates 17 at both ends of its outer periphery to move. Due to the limit rod 18, the support plates 17 at both ends of its outer periphery can move. The movement direction of the support plate 17 is constrained by the 5, so that the two support plates 17 can move stably in opposite directions, thereby achieving the purpose of clamping the goggles. More importantly, during the rotation of the roller 3 driven by the servo motor 8, the goggles are always perpendicular to the ground due to their own gravity, thus ensuring that both sides of the goggles are always in a stable state ready to be sprayed during the spraying process. At the same time, the empty trays 9 and several nozzles 10 on both sides of the inner wall of the spray box 1 can spray the vertical goggles simultaneously from both sides without the need for manual or additional equipment to flip them over. This eliminates the traditional mode of needing a second operation after spraying one side of the conveyor belt, greatly shortens the spraying process, and significantly improves the spraying efficiency and spraying uniformity.

[0029] The collection assembly includes two water pumps 4 fixedly installed inside the collection tank 2. Connecting pipes 7 are fixedly connected to both sides of the spraying tank 1. The output ends of the water pumps 4 are fixedly connected to the corresponding connecting pipes 7. The ends of the connecting pipes 7 away from the water pumps 4 extend into the interior of the corresponding empty trays 9. A drain outlet 12 is provided between the spraying tank 1 and the collection tank 2. The two water pumps 4 in the collection tank 2 can transport the spray liquid in the tank to the empty trays 9 through the connecting pipes 7, and then reuse it for spraying through the nozzles 10. The spray liquid that does not adhere to the goggles will flow back into the collection tank 2, forming a spray liquid recycling system. This structure effectively recovers the spray liquid that does not adhere to the goggles during the spraying process, avoids the waste of raw materials, reduces production costs, and reduces the environmental impact of random discharge of spray liquid, combining economic efficiency and environmental protection.

[0030] The support plates 17 are all slidably connected to the outer periphery of the limiting rod 15, and the rubber pad 18 has a convex surface inside that fits against the outer wall of the goggles to ensure that it is firmly clamped and does not damage the goggles.

[0031] A servo motor 8 is fixedly installed on the rear side of the spray box 1. The output shaft of the servo motor 8 extends into the interior of the spray box 1 and is fixedly connected to the rotation shaft of the rotating roller 3. The rotation of the output shaft of the servo motor 8 drives the rotating roller 3 to rotate, thereby realizing the transmission of power.

[0032] A water level sensor 5 is fixedly installed on the inner wall of the collection box 2. The water level sensor 5 can monitor the water level of the spray liquid in the collection box 2 in real time. Three alarms 6 are fixedly installed on the top of the spray box 1.

[0033] The spray box 1 is equipped with a controller on the outside. When the water level is too low or too high, the three alarms 6 on the top of the spray box 1 will sound an alarm to remind the staff to replenish the spraying liquid through the water inlet 19 or deal with the abnormal situation in time, so as to avoid the spraying quality being affected by insufficient spraying liquid or leakage caused by excessive water level. The spray box 1 is equipped with a viewing window on the outer periphery, and the water inlet 19 is fixedly connected to the outside of the collection box 2.

[0034] Both sides of the spray box 1 are hinged with opening and closing doors 20. The bottom of the inner wall of the spray box 1 is provided with a slope for drainage. The slope facilitates the rapid discharge of the spray liquid in the spray box 1.

[0035] In this invention, the working steps of the device are as follows:

[0036] First step: First, the staff can open the opening and closing door 20 and place the goggles between the two support plates 17. Then, the double-acting screw 16 is rotated, which can drive the support plates 17 at both ends of its outer periphery to move, so that the two support plates 17 can move stably in opposite directions, thereby achieving the purpose of clamping the goggles. Then, as the servo motor 8 drives the rotating roller 3 to rotate, due to the gravity of the goggles themselves, the goggles are always perpendicular to the ground, thus ensuring that both sides of the goggles are always in a stable state ready to be sprayed during the spraying process. At the same time, the empty trays 9 and several nozzles 10 on both sides of the inner wall of the spray box 1 can spray the vertical goggles simultaneously from both sides, without the need for manual or additional equipment to flip them over.

[0037] The second step involves two water pumps 4 inside the collection tank 2, which transport the spray liquid inside the tank to the empty tray 9 through the connecting pipe 7, and then reuse it for spraying through the nozzle 10. The spray liquid that does not adhere to the goggles will flow back into the collection tank 2, forming a spray liquid recycling system. This structure effectively recovers the spray liquid that does not adhere to the goggles during the spraying process, avoids the waste of raw materials, reduces production costs, and reduces the environmental impact of random discharge of spray liquid.
