Description

Technical Field

[0001] This utility model relates to the field of coating machine technology, specifically a high-efficiency coating machine. Background Technology

[0002] The coating machine mainly consists of a coating pan, a hot air blower, an exhaust fan, and a spray system. Its working principle is as follows: granules are placed inside the pan, where they tumble and mix due to the pan's rapid rotation. During this process, a spray gun mounted above the pan continuously sprays atomized liquid required for coating, while hot air is supplied to the pan under negative pressure, ensuring the liquid sprayed onto the granule surface dries quickly and evenly. Because of the continuous tumbling motion of the granules within the pan, this process is repeated continuously, gradually coating the granule surface with a film.

[0003] CN215274581 U discloses a high-efficiency coating machine, including a housing with an inlet and an outlet. A liquid storage tank is located above the housing, and the liquid storage tank has a spray nozzle. A mixing tank is located inside the housing, hinged to a symmetrically arranged fixed shaft. A driven gear is mounted on the fixed shaft. A self-locking drive motor is fixed inside the housing, and a drive gear is mounted on the self-locking drive motor, meshing with the driven gear. A pulsator is located at the lower end of the mixing tank, and a pulsator motor is mounted on the pulsator and fixed to the lower end of the mixing tank. This high-efficiency coating machine, with its internal mixing tank equipped with a pulsator for coating materials, allows the mixing tank to rotate and discharge the coated material. It features a high degree of automation and provides uniform coating and high efficiency.

[0004] The aforementioned patent addresses the shortcomings of existing coating machines, which lack a mixing function, resulting in uneven coating and low coating efficiency. This technical solution uses a pulsator at the bottom of the mixing tank, which, in conjunction with the tank's rotation, tumbles the tablets. However, this solution involves a deep mixing tank, and the pulsator is located at the bottom. For tablets at the top of the tank, the pulsator's force is insufficient, leading to uneven tablet tumbling and affecting the coating effect. Therefore, a high-efficiency coating machine is proposed to solve these problems. Utility Model Content

It solves the problem that the existing coating machines have a deep mixing tank and the impeller is located at the bottom of the mixing tank. For tablets in the upper part of the tank, the impeller's force is insufficient, resulting in uneven tablet tumbling and affecting the coating effect.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a high-efficiency coating machine, comprising a support frame, wherein a coating mechanism is provided on the support frame;

[0007] The coating mechanism includes a connecting ring fixedly installed on the top of the support. A coating pan is rotatably installed inside the connecting ring.

[0022] 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.

[0023] Please see Figures 1 to 4This embodiment of a high-efficiency coating machine includes a support 1, on which a coating mechanism is provided. The coating mechanism includes a connecting ring 2 fixedly installed on the top of the support 1. A coating pan 3 is rotatably installed inside the connecting ring 2. An annular groove 14 is formed on the inner surface of the connecting ring 2. A sliding ring 15 is fixedly inserted into the annular groove 14 on the side surface of the coating pan 3. The sliding ring 15 is adapted to the annular groove 14 to facilitate the rotation of the coating pan 3 inside the connecting ring 2. Multiple arc-shaped protrusions 4 are fixedly installed inside the coating pan 3. The multiple arc-shaped protrusions 4 are evenly distributed. Distributed on the inner surface of the coating pan 3, multiple electric telescopic rods 5 are fixedly installed on the top of the connecting ring 2. A mounting plate 6 is fixedly installed at the output end of each electric telescopic rod 5. A liquid storage tank 7 is fixedly installed on the upper surface of the mounting plate 6, and a liquid outlet pipe 8 is fixedly installed on the lower surface of the mounting plate 6. An atomizing nozzle 9 and a lever 10 are fixedly installed on the surface of the liquid outlet pipe 8. A rubber rod 11 is fixedly installed on the surface of the lever 10. A liquid supply pump 12 is fixedly installed inside the liquid storage tank 7, and a connecting pipe 13 is fixedly installed at the outlet end of the liquid supply pump 12, penetrating the liquid storage tank 7 and connecting to the liquid outlet pipe 8.

[0024] Among them, there are multiple atomizing nozzles 9 and levers 10, which are evenly distributed on the surface of the liquid outlet pipe 8. Each lever 10 has two rubber rods 11, which are inclinedly arranged on the surface of the lever 10.

[0025] It should be noted that a protective cover 16 is fixedly installed on the lower surface of the mounting plate 6, and the liquid outlet pipe 8 and the atomizing nozzle 9 are located inside the protective cover 16. The protective cover 16 helps to reduce the diffusion of the coating liquid. A hot air blower 17 is fixedly installed on the upper surface of the mounting plate 6, and the air outlet of the hot air blower 17 extends through to the lower surface of the mounting plate 6.

[0026] A rotating assembly is provided between the support 1 and the coating pan 3. The rotating assembly includes a transmission ring 18 fixedly installed on the lower surface of the coating pan 3. The side surface of the transmission ring 18 is provided with an annular tooth groove 19. A fixed support plate 20 is fixedly installed on the surface of the support 1. A motor 21 is fixedly installed on the surface of the fixed support plate 20. A gear 22 that meshes with the annular tooth groove 19 is fixedly installed on the output shaft of the motor 21.

[0027] It should be noted that the bottom surface of the coating pan 3 is inclined, and a discharge pipe 23 connected to the coating pan 3 is fixedly installed at the bottom of the coating pan 3. A sealing cap 24 is threadedly connected to the bottom of the discharge pipe 23. A plunger 25 is fixedly installed on the inner surface of the sealing cap 24, which is inserted into the discharge pipe 23 and aligned with the top surface of the discharge pipe 23. By setting the plunger 25, the internal cavity of the discharge pipe 23 can be filled, which can prevent some tablets from falling into the discharge pipe 23 during the coating process and failing to complete the coating.

[0028] It should be noted that a synchronization controller was used to achieve synchronized operation of multiple electric telescopic poles 5. This controller can monitor the position and speed of multiple electric telescopic poles 5 in real time and ensure that they remain synchronized by adjusting the output parameters of multiple electric telescopic poles 5.

[0029] The working principle of the above embodiments is as follows:

[0030] The tablets to be coated are placed in the coating pan 3. According to the coating requirements, an appropriate amount of coating solution is added to the storage tank 7. The electric telescopic rod 5 drives the mounting plate 6 downwards, causing the lever 10 and rubber rod 11 to contact the tablets in the coating pan 3. The motor 21 is started, driving the gear 22 to rotate. The gear 22 meshes with the annular toothed groove 19, causing the transmission ring 18 to rotate, thus driving the coating pan 3 to rotate stably within the connecting ring 2. The liquid supply pump 12 is started, pumping the coating solution from the storage tank 7 to the outlet pipe 8 through the connecting pipe 13, and then atomized and sprayed from the surface of the outlet pipe 8. The head 9 atomizes the coating solution into fine particles and sprays them evenly onto the surface of the tablets inside the coating pan 3. As the coating pan 3 rotates, the arc-shaped protrusion 4 stirs and pushes the tablets. The lever 10 and the rubber rod 11 simultaneously move the tablets, further promoting the tablets to tumble continuously inside the coating pan 3, ensuring that the tablets can fully contact the atomized coating solution. The hot air blower 17 is started, and the hot air generated by the hot air blown into the coating pan 3 through its air outlet to accelerate the drying of the coating solution. After coating is completed, the sealing cover 24 at the bottom of the discharge pipe 23 is opened. The sloping design at the bottom of the coating pan 3 facilitates the concentrated discharge of the coated tablets from the discharge pipe 23.
