[0028] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0029] like Figures 1 to 6 As shown, a pharmaceutical aluminum bottle processing and spraying equipment includes a spraying box 1, a spraying mechanism, and a positioning mechanism. A partition 2 is disposed in the middle of the spraying box 1. A rotating groove 21 is formed on the partition 2. The positioning mechanism includes a turntable 3 and an air pump 4. The turntable 3 is rotatably disposed within the rotating groove 21. Several suction holes 31 are formed in the center of the turntable 3. The air pump 4 is fixedly disposed at the bottom of the turntable 3, and the suction holes 31 are connected to the air pump 4. An aluminum bottle is placed at each suction hole 31, and the air pump 4 suctions and fixes the aluminum bottle, effectively preventing the aluminum bottle from shaking or shifting during high-speed rotation and spraying, ensuring the accuracy and quality of the spraying, and making the coating on the aluminum bottle uniform and consistent.

[0030] The air pump 4 is fixedly equipped with a rotating mechanism at its bottom; the top of the partition 2 is provided with a return groove 22, which is located on the outer ring of the rotating groove 21, and a number of leakage holes 23 are provided on the return groove 22; the bottom of the partition 2 is provided with a recycling box 5, which is connected to the leakage holes 23; and the spraying mechanism is set on the side wall of the spraying box 1 to spray aluminum bottles.

[0031] The rotating mechanism includes a first motor 6 and a rotating shaft 61. The first motor 6 is fixedly installed inside the spray box 1 and located at the bottom of the partition 2. One end of the rotating shaft 61 is connected to the output end of the first motor 6, and the other end is fixedly connected to the bottom of the air pump 4. The air pump 4 is installed through the partition 2.

[0032] The first motor 6 is the power source of the rotating turntable 3. When the motor is started, the output torque is transmitted to the air pump 4 and the turntable 3 through the rotating shaft 61, so that the air pump 4 and the turntable 3 make a circular motion around the central axis of the rotating groove 21. Since the air pump 4 is fixedly connected with the turntable 3, the aluminum bottle adsorbed on the turntable 3 rotates synchronously. The stable rotation ensures that each part of the aluminum bottle is evenly coated with paint during spraying, thereby improving the product quality. The top of the partition plate 2 is provided with a plurality of guide grooves 24, which are arranged in an annular array along the return groove 22. The bottom of the guide groove 24 is arranged to be inclined along the direction of the return groove 22.

[0033] The guide groove 24 provides a guide path for the excess paint falling according to the principle of fluid mechanics. The bottom of the guide groove 24 is arranged to be inclined along the direction of the return groove 22, and the paint can flow naturally and quickly to the return groove 22 by gravity, effectively guiding the paint to flow back, keeping the top of the partition plate 2 clean, preventing the paint from drying on the partition plate 2 and affecting the placement and rotation of the aluminum bottle, and reducing the product quality problems caused by paint residue, thereby improving the production continuity.

[0034] The spraying mechanism comprises a paint tank 7, a connecting pipe 71, a spraying pipe 72 and a nozzle 73. The paint tank 7 is arranged outside one side of the spraying box 1. The top of the paint tank 7 is provided with the connecting pipe 71. One end of the connecting pipe 71 is in communication with the paint tank 7, and the other end penetrates through the side wall of the spraying box 1 and is connected with the spraying pipe 72. The spraying pipe 72 is fixedly arranged on the lifting platform 74. The nozzle 73 is arranged on the side wall of the lifting platform 74 and is in communication with the spraying pipe 72. The nozzle 73 adopts a fan-shaped nozzle. The side wall of the spraying box 1 is provided with a lifting groove 11. A lead screw 81 is rotatably arranged in the lifting groove 11. One end of the lifting platform 74 is arranged on the lead screw 81. A second motor 8 is arranged on the top of the spraying box 1. The output end of the second motor 8 is connected with the lead screw 81.

[0035] The paint tank 7 stores paint. The connecting pipe 71 serves as a conveying channel to introduce the paint into the spraying pipe 72. When the second motor 8 drives the lead screw 81 to lift the lifting platform 74, the spraying pipe 72 and the nozzle 73 move synchronously. When the nozzle 73 approaches the aluminum bottle, the paint is sprayed from the fan-shaped nozzle under the action of pressure. Due to the special shape of the fan-shaped nozzle, the paint is scattered in a fan shape, covering a large area and being evenly sprayed, thereby realizing comprehensive spraying of the aluminum bottle.

[0036] One side of the recycling box 5 is provided with a flow pipe 51 in communication. The flow pipe 51 is in communication with the paint tank 7.

[0037] The recycling box 5 collects the excess paint flowing from the leakage hole 23 of the return groove 22 by using its own volume. When the paint in the recycling box 5 reaches a certain amount, the paint flows back to the paint tank 7 through the flow pipe 51 under the action of gravity or the assistance of a pump, thereby realizing the recycling of the paint.

[0038] The rotating groove 25 is arranged in the rotating groove 21, and the rotating disc 3 is provided with a plurality of ball bearings 32 arranged at the bottom of the rotating disc 3 and matched with the rotating groove 25.

[0039] The ball bearings 32 are arranged between the bottom of the rotating disc 3 and the rotating groove 25, and when the rotating disc 3 rotates, the ball bearings 32 roll in the rotating groove 25, and the original sliding friction between the rotating disc 3 and the rotating groove 21 is changed into rolling friction. The rolling friction coefficient is much smaller than the sliding friction coefficient, which greatly reduces the resistance of the rotating disc 3, enables the rotating disc 3 to rotate more smoothly and stably, reduces the load of the motor, and prolongs the service life of the equipment.

[0040] The sealing groove 26 is arranged at the bottom of the side wall of the rotating groove 21, and the sealing ring 33 is arranged at the bottom of the rotating disc 3 and arranged in the sealing groove 26.

[0041] The sealing ring 33 is arranged at the bottom of the rotating disc 3 and matched with the sealing groove 26 at the bottom of the side wall of the rotating groove 21, so as to form a sealing barrier and prevent the paint from seeping into the bottom of the rotating groove 21 from the gap between the rotating disc 3 and the rotating groove 21 during the rotation of the rotating disc 3. The sealing ring 33 is matched with the sealing groove 26 under the pressure, and the paint is prevented from seeping out by the sealing characteristics of the elastic material such as rubber.

[0042] The working principle of the present application is as follows: first, the aluminum bottle to be sprayed is placed above the adsorption hole 31 of the rotating disc 3, and the air pump 4 is started to generate negative pressure, so as to tightly adsorb the aluminum bottle through the adsorption hole 31 and ensure the stability of the position of the aluminum bottle in the subsequent processing process. Then, the first motor 6 arranged at the bottom of the partition plate 2 in the spraying box 1 is started to drive the rotating shaft 61 to rotate, and then drive the rotating disc 3 and the air pump 4 to rotate as a whole, so that the aluminum bottle rotates at a constant speed, and conditions for uniform spraying are created. At the same time, the spraying mechanism starts to work, the paint in the paint tank 7 is delivered to the spraying pipe 72 through the hydraulic pump and the connecting pipe 71, and the nozzle 73 arranged on the side wall of the lifting platform 74 is aligned with the rotating aluminum bottle. The second motor 8 arranged at the top of the spraying box 1 drives the screw rod 81 to rotate in the lifting groove 11, drives the spraying pipe 72 and the nozzle 73 on the lifting platform 74 to ascend and descend according to the preset spraying track, and the nozzles 73 of the fan-shaped spray heads uniformly spray the paint on the surface of the aluminum bottle. During the spraying process, the excess paint drops on the top of the partition plate 2, flows into the backflow groove 22 along the guide groove 24, and then is collected into the recycling box 5 through the leakage hole 23. Part of the paint in the recycling box 5 can also flow back to the paint tank 7 through the flow-through pipe 51, so as to realize the recycling of the paint.

[0043] The foregoing description of the disclosed embodiments enables a person skilled in the art to make or use the application. Modifications of these embodiments will occur to persons of skill in the art, and, while certain modifications are discussed, it is desired to be protected in accordance with the spirit and scope of the application.
