[0034] Liquid inlet pipe 200 with the kettle body 300 is installed on the top surface of the body 100, and the kettle body 300 is rotatably connected to the body 100.

[0035] The liquid inlet pipe 200 is connected to a spray head 400 at one end away from the top surface of the body 100, and the spray head 400 is in communication with the one end of the liquid inlet pipe 200 away from the top surface of the body 100 through a valve.

[0036] The spray head 400 is located inside the kettle body 300, and the spray head 400 is provided with a flow control assembly 500 to adjust the opening degree of the spray head 400.

[0037] In this embodiment, the liquid inlet pipe 200 is used to transport coating agents, the kettle body 300 is used to place tablets to be coated, the kettle body 300 is rotatably connected to the body 100, and the tablets inside the kettle body 300 are uniformly heated and coated by rotating the kettle body 300. The liquid inlet pipe 200 is connected to a spray head 400 at one end close to the kettle body 300, the spray head 400 is arranged inside the kettle body 300, and the spray head 400 is used to uniformly spray the coating agents on the tablets in the kettle body 300 to coat the tablets. The spray head 400 is provided with a flow control assembly 500 to adjust the opening degree of the spray head 400. The greater the opening degree, the more coating agents are sprayed by the spray head 400, and vice versa. The opening degree of the spray head 400 is adjusted according to the size of the tablets in actual use, the flow of the coating agents is adjusted by setting the flow control assembly 500, so that the equipment can adapt to tablets of various sizes, and the thickness and uniformity of the coating layer of tablets of different sizes are guaranteed.

[0038] In one of the embodiments, the spray head 400 includes a first spray head and a second spray head, and the first spray head and the second spray head are in communication with the one end of the liquid inlet pipe 200 away from the top surface of the body 100 through a three-way control valve 600.

[0039] The first spray head and the second spray head are both located inside the kettle body 300, and the first spray head and the second spray head are both provided with a flow control assembly 500.

[0040] In the embodiment, the spray head 400 comprises a first spray head and a second spray head, through the design of the first spray head and the second spray head, the flow of the coating agent can be further increased. The first spray head and the second spray head are connected with the liquid inlet pipe 200 through the three-way control valve 600, the coating agent transported by the liquid inlet pipe 200 flows into the first spray head and the second spray head through the three-way control valve 600, through the three-way control valve 600, the flow of the coating agent into one of the spray heads 400 can be controlled; the first spray head and the second spray head are both provided with the flow control assembly 500 to control the flow of the coating agent.

[0041] In one of the embodiments, as shown in Fig. 2 、 Fig. 3 , the first spray head 400 and the second spray head 400 are the same in structure, both in tubular design. The first spray head 400 and the second spray head 400 both comprise a connecting section 410 and a spraying section 420, one end of the connecting section 410 is connected with the spraying section 420, and the other end is connected with the three-way control valve 600;

[0042] The end of the spraying section 420 away from the connecting section 410 is closed, so that the coating agent flowing into the spraying section 420 cannot directly flow into the kettle body 300; a plurality of through holes 421 are formed in the side of the spraying section 420, a nozzle 422 is arranged in each through hole 421, and the nozzles 422 arranged in each through hole 421 are flush with the side of the spraying section 420, so as to ensure that the flow control assembly 500 can slide normally; a limiting block 423 is arranged on the outer side of the end of the spraying section 420 away from the connecting section 410, the limiting block 423 is designed to limit the sliding range of the flow control assembly 500.

Specifically, when the sleeve 510 is located on the connecting section 410, the flow of the coating machine is the largest, when it is necessary to adjust the spraying flow of the coating agent in the spraying section 420 to be smaller, the sleeve 510 is slid on the connecting section 410, so that the sleeve 510 gradually closes the through holes 421 of the spraying section 420, so that the nozzles on the through holes 421 cannot spray the coating agent, thereby reducing the spraying amount of the coating agent, when the sleeve 510 slides to the limit position, that is, one end of the sleeve 510 abuts against the limiting block 423 at the end of the spraying section 420, at this time, all the through holes 421 are closed. The sealing rubber ring 520 plays a sealing role, and also plays a anti-slip role, preventing the sleeve 510 from sliding automatically when it is not necessary to slide the sleeve 510.

[0044] In one of the embodiments, the body 100 is provided with a control panel 700.

[0045] In the present embodiment, the control panel 700 is used to control the rotation of the pot body 300 and the flow of the coating agent into the liquid inlet pipe 200.

[0046] According to the need, the above-mentioned installation, arrangement, provision or connection mode includes but is not limited to screwing, riveting, welding or sleeving, fixing and the like, and the installation, arrangement or connection mode is selected according to the working situation.

[0047] The above-mentioned is only the preferred embodiment of the present application, and does not limit the patent range of the present application, and any equivalent structural transformation made by using the content of the present application specification and drawings, or direct / indirect application in other related technical fields under the utility model concept of the present application is included in the patent protection range of the present application.
