Description

Technical Field

[0001] This utility model relates to the field of spraying equipment technology, and in particular to a spraying device for preparing metal-ceramic solar heat-absorbing films. Background Technology

[0002] Metal ceramics have a wide range of applications. They are generally used directly as tableware in the food industry. Some plastic tableware is also decorated with vacuum coating, surface spraying, hot stamping, etc. However, most decorative films often leave rust and fingerprints on the surface of coated tableware because they do not have wear-resistant and corrosion-resistant properties during storage. Ceramic films, on the other hand, can absorb heat and require spraying on the surface of the metal ceramic during the manufacturing process. Ceramic films have a wide range of applications, possessing high barrier properties, high temperature resistance, transparency, and good microwave transmittance. They not only improve the decorative effect of plastic tableware but also enhance the corrosion resistance of the film, thereby improving the product's market competitiveness.

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] This utility model discloses a spraying device for preparing metal-ceramic solar heat-absorbing films, such as... Figures 1-5 As shown, it includes a spraying station 1 and a nozzle 1028 disposed on the top surface of the spraying station 1 for preparing a metal-ceramic solar heat-absorbing film. A storage box 2 is provided on one side of the top surface of the spraying station 1, which can store the spraying liquid used for spraying in the storage box 2.

[0023] The top surface of the spray booth 1 is slidably connected to a dust cover 3. The dust cover 3 is made of stainless steel and has multiple observation windows embedded on its outer surface. The observation windows allow the staff to observe the inside of the dust cover 3 in real time during ceramic spraying.

[0024] A first electric actuator 4 is fixedly installed on the bottom surface of the spraying station 1, and the output end of the first electric actuator 4 is fixedly connected to the dust cover 3. The first electric actuator 4 can push the dust cover 3 to move, so as to realize the opening and closing of the dust cover 3. When spraying, the first electric actuator 4 drives the dust cover 3 to move, and the dust cover 3 covers the top surface of the spraying station 1 to reduce the adhesion rate of impurities. After the spraying is completed, the first electric actuator 4 drives the dust cover 3 to move in the opposite direction, so that the top surface of the spraying station 1 is exposed, so as to remove the sprayed ceramic. A processing component is provided on one side of the bottom surface of the spraying station 1.

[0025] The processing components include a negative pressure fan 102 fixedly installed on one side of the bottom surface of the spray table 1. After the negative pressure fan 102 is powered on, the motor of the negative pressure fan 102 drives the impeller to rotate at high speed. The rotating blades push the surrounding air, giving the air kinetic energy and centrifugal force. As the air is continuously thrown outward from the center of the impeller, the air in the central area of ​​the impeller is drawn away, resulting in a decrease in air pressure in that area, forming a relative negative pressure. The external atmospheric pressure is higher than the air pressure at the air inlet of the fan, and air continuously flows in through the air inlet to fill the volume of the drawn-away air, forming a continuous airflow.

[0026] Since the negative pressure fan 102 is existing technology, it will not be described in detail here. In actual work, the appropriate type of negative pressure fan 102 can be selected according to the needs. The type of negative pressure fan 102 is not limited here.

[0027] A water tank 104 is fixedly installed on one side of the bottom surface of the spraying station 1. The water tank 104 contains water. The inlet of the negative pressure fan 102 is provided with a stainless steel corrugated pipe 101, and the end of the stainless steel corrugated pipe 101 away from the negative pressure fan 102 extends into the interior of the dust cover 3.

[0028] The outlet of the negative pressure fan 102 is fixedly installed with a connecting pipe 103, and the connecting pipe 103 is fixedly connected to the water storage tank 104. The negative pressure fan 102 can transmit the air inside the dust cover 3 to the water storage tank 104 and come into contact with the water in the water storage tank 104. Solid impurities in the air will enter the water, thus achieving the effect of treating solid impurities in the air.

[0029] The bottom surface of the water storage tank 104 is equipped with a valve. Opening the valve will allow water containing impurities to be discharged. Workers can refill the water storage tank 104 with water through a pipe threadedly connected to the adsorption cylinder 105.

[0030] Activated carbon particles can be placed inside the adsorption cylinder 105. Air flowing out of the water storage tank 104 will enter the adsorption cylinder 105. The activated carbon particles capture odor molecules through their porous structure, thus adsorbing odors in the air. This can deodorize the inside of the dust cover 3 after spraying, reducing the amount of odors that workers inhale when they open the dust cover 3.

[0031] The top surface of the spraying station 1 is embedded with a recycling cylinder 5. A carrier plate 501 is fixedly installed on the top opening of the recycling cylinder 5 so that the ceramic to be sprayed can be placed on the top surface of the carrier plate 501 for spraying. During the spraying process, the spray liquid dripping will fall into the recycling cylinder 5 and be discharged through the opening at the bottom of the recycling cylinder 5. During the spraying process, the opening at the bottom of the recycling cylinder 5 is sealed by an external sealing plug. After the spraying is completed, the sealing plug can be pulled out to discharge the collected spray liquid.

[0032] A sealing strip 205 is fixedly installed on the outer surface of the storage tank 2 near the dust cover 3, and a liquid replenishment pipe 201 is provided on one side of the outer surface of the storage tank 2. A pump body 202 is fixedly installed on the outer surface of the storage tank 2 on the side of the sealing strip 205. The inlet of the pump body 202 is fixedly connected to the storage tank 2 with a liquid inlet pipe 204, and the outlet of the pump body 202 is provided with a fluororubber hose 203. The fluororubber hose 203 is fixedly connected to the nozzle 1028. The pump body 202 can transfer the spraying liquid in the storage tank 2 to the nozzle 1028 through the fluororubber hose 203 and the liquid inlet pipe 204. The nozzle 1028 can then spray the spraying liquid onto the ceramic on the top surface of the carrier plate 501.

[0033] A circular electric guide rail 1021 is fixedly installed on the top surface of the spraying station 1, and the circular electric guide rail 1021 surrounds the work plate 501. Two telescopic rods 1023 are fixedly installed on the top surface of the slider 1022 of the circular electric guide rail 1021. A fixed gear is installed on the body of the circular electric guide rail 1021. The gear inside the slider 1022 is driven by a motor. When the motor rotates, the gear of the slider 1022 revolves around the fixed gear to achieve circular motion. When the circular electric guide rail 1021 is running, the slider 1022 can move along the guide rail. Since the circular electric guide rail 1021 is existing technology, it will not be described in detail here.

[0034] Furthermore, a fixing plate 1025 is fixedly installed at the top of both telescopic rods 1023, and a second electric push rod 1024 is fixedly installed on the top surface of the slider 1022. When the slider 1022 moves along the guide rail, it can drive the fixing plate 1025 and the second electric push rod 1024 to move.

[0035] Furthermore, the output end of the second electric actuator 1024 is fixedly connected to the fixed plate 1025. The second electric actuator 1024 can push the fixed plate 1025 to rise or fall. When the fixed plate 1025 rises or falls, the two telescopic rods 1023 will rise or fall accordingly.

[0036] A ball seat 1026 is fixedly installed on the top surface of the fixing plate 1025. A ball head 1027 is provided inside the ball seat 1026. A fastening bolt 1029 is threadedly connected to one side of the outer surface of the ball seat 1026. The ball head 1027 is fixedly connected to the nozzle 1028.

[0037] The ball head 1027 can rotate freely inside the ball seat 1026. The operator can manually rotate the fastening bolt 1029 to make it press against the ball head 1027, thus fixing the ball head 1027. The free rotation of the ball head 1027 can adjust the angle of the nozzle 1028. With the help of the circular electric guide rail 1021 and the second electric push rod 1024, the height, position and angle of the nozzle 1028 can be adjusted to spray ceramics.

[0038] A sealing groove 301 is provided on one side of the outer surface of the dust cover 3. A rubber pad 302 is provided on the inner wall of the sealing groove 301. When the dust cover 3 covers the spray table 1, the sealing strip 205 will be inserted into the sealing groove 301. During the insertion process, the rubber pad 302 will be squeezed and deformed to improve the sealing effect between the sealing strip 205 and the sealing groove 301.

[0039] The working principle of this utility model is as follows: The operator first starts the first electric actuator 4, which pushes the dust cover 3 to open the dust cover 3. Then, the ceramic to be sprayed is placed on the top surface of the carrier plate 501. The height and angle of the nozzle 1028 are adjusted by rotating the ball head 1027 and starting the second electric actuator 1024. Then, the spraying liquid is injected into the storage tank 2 through the liquid replenishment pipe 201, water is injected into the water storage tank 104, and activated carbon particles are poured into the adsorption cylinder 105. The pipe of the adsorption cylinder 105 is then threadedly connected to the water storage tank 104.

[0040] Afterwards, the staff will start the first electric actuator 4 again to close the dust cover 3 and cover the top surface of the spray table 1. Then, the negative pressure fan 102 can be started to pre-clean the inside of the dust cover 3. After pre-cleaning, the pump body 202 can be started to spray the ceramic with the nozzle 1028.

[0041] After the spraying is completed, the negative pressure fan 102 is started again to extract the odor from inside the dust cover 3. Then, the staff can start the first electric push rod 4 to open the dust cover 3 and take out the sprayed ceramic.
