Description

Technical Field

[0001] The utility model relates to the technical field of coating machines, and more specifically, to a coating machine for producing tablets. Background Art

[0002] A coating machine is a device used to coat pharmaceuticals, foods, and other products. It primarily consists of a main unit, hot air system, and spray gun system. Coating can improve the appearance of pharmaceuticals or foods, making them more aesthetically pleasing and appealing. It also protects them from moisture and oxidation, extending their shelf life. Furthermore, coating can mask unpleasant odors and flavors, making them more acceptable to patients or consumers.

[0003] The core component of the existing coating machine is the coating pot. The drug rotates in the coating pot, and the liquid is covered on the tablets through the mist nozzle to achieve the coating effect. However, when the smaller and larger number of medicine particles roll in the coating pot, some medicine particles will always stay in the middle position and are difficult to be evenly sprayed with the original liquid. Therefore, the outer side of some medicine particles cannot be fully coated by the original liquid. Utility Model Content

The technical problem to be solved by the present invention is that when too many smaller medicine particles roll in the coating pot, some of the medicine particles will always be in the middle position and difficult to be evenly sprayed with the stock solution. Therefore, the outer sides of some medicine particles cannot be fully wrapped by the stock solution.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

The inclined plate supports the tablets, thereby driving the tablets in the coating pot to move upward along the inner wall of the coating pot. Since the inclined plate is installed at an angle, after reaching a certain degree, the tablets will slide down from the inclined plate one by one, forming a thin waterfall shape, and the falling tablets are sprayed by the liquid inlet pipe and the atomizing nozzle, thereby achieving tablet coating.

[0008] In a preferred embodiment, the driving mechanism includes a first motor, and the first motor is fixedly mounted on the side of the mounting base, the output shaft of the first motor is equipped with a driving gear, the outer side of the turntable is equipped with a driven gear, and the driving gear is meshed with the driven gear.

[0009] In a preferred embodiment, the liquid pumping mechanism includes a water pump, and the water pump is fixedly installed on the outside of the liquid storage barrel, and the water pump is connected to the inside of the liquid storage barrel. A connecting pipe is fixed and connected to the outside of the water pump, and the connecting pipe is connected to the liquid inlet pipe. A stirring mechanism is provided in the liquid storage barrel.

[0010] In a preferred embodiment, the stirring mechanism includes a stirring shaft, and the stirring shaft is rotatably connected in the liquid storage barrel, and a plurality of stirring rods are fixedly installed on the outer side of the stirring shaft.

[0014] In a preferred embodiment, two infrared heating plates are symmetrically installed on the outside of the control box, and a discharge pipe is fixed to and connected to the outside of the coating pot.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. The utility model realizes that the driving gear drives the driven gear to rotate, and then the inclined plate is driven to rotate by the rotation of the turntable, so that the inclined plate supports the tablets, thereby driving the tablets in the coating pot to move upward along the inner wall of the coating pot. After reaching a certain angle, the tablets will slide down from the inclined plate in sequence, forming a thin waterfall shape, so that the medicines located in the middle will also fall in sequence in the shape of a waterfall, and will be sprayed with the original liquid through the atomizing nozzle, thereby achieving the purpose of uniform coating of the tablets.

[0017] 2. The utility model realizes the purpose of uniform color of each tablet coating by arranging a stirring rod, a stirring shaft, a second motor and other devices, so that the stirring shaft is driven to rotate by the second motor, and then the liquid storage barrel is stirred by the stirring rod, thereby avoiding the static stratification and precipitation of the original liquid.

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] Reference Figure 1-4 A coating machine for producing tablets includes a base 1, a control box 2 and a liquid storage barrel 3 are respectively installed on the top surface of the base 1, the outer side of the liquid storage barrel 3 is fixed and connected with a pumping mechanism, a coating pot 4 is fixedly installed on the outer side of the control box 2, a mounting seat 8 is fixedly installed in the coating pot 4, a liquid inlet pipe 7 is fixedly installed in the mounting seat 8, and the liquid inlet pipe 7 is connected with the pumping mechanism, one end of the liquid inlet pipe 7 extends into the coating pot 4 and is installed with a plurality of atomizing nozzles 11, the outer side of the liquid inlet pipe 7 is rotatably connected with a turntable 12, and the mounting seat 8 drives the turntable 12 to rotate through a driving mechanism, and a plurality of connecting rods 9 are symmetrically installed on the outer side of the turntable 12, and an inclined plate 10 is fixedly installed on the outer side of each connecting rod 9, and one end of each inclined plate 10 is in contact with the inner wall of the coating pot 4.

[0027] like Figure 1-5 As shown, the specific implementation method is as follows: by setting a driving mechanism and a turntable 12, the turntable 12 rotates slowly, and through the connecting rod 9 and the inclined plate 10, the turntable 12 rotates and the inclined plate 10 is driven to rotate by the connecting rod 9. The inclined plate 10 supports the tablets, thereby driving the tablets in the coating pot 4 to move upward along the inner wall of the coating pot 4. Since the inclined plate 10 is installed at an angle, after reaching a certain degree, the tablets will slide down from the inclined plate 10 one by one, forming a thin waterfall shape, and the falling tablets are sprayed by the liquid inlet pipe 7 and the atomizing nozzle 11, thereby achieving tablet coating.

[0028] The driving mechanism includes a first motor 15 , and the first motor 15 is fixedly mounted on the side of the mounting base 8 , the output shaft of the first motor 15 is mounted with a driving gear 13 , the outer side of the turntable 12 is mounted with a driven gear 14 , and the driving gear 13 is meshed with the driven gear 14 .

[0029] It is worth noting that the mounting seat 8 is fixedly installed in the coating pot 4, but there is a space between the mounting seat 8 and the coating pot 4, through which the tablets can be input into the knife coating pot 4, and the driving gear 13 is driven to rotate by the first motor 15, thereby driving the turntable 12 to rotate.

[0030] The liquid pumping mechanism includes a water pump 19, and the water pump 19 is fixedly installed on the outside of the liquid storage barrel 3, and the water pump 19 is connected to the inside of the liquid storage barrel 3. A connecting pipe 20 is fixed and connected to the outside of the water pump 19, and the connecting pipe 20 is connected to the liquid inlet pipe 7. A stirring mechanism is provided in the liquid storage barrel 3.

[0031] The stirring mechanism includes a stirring shaft 17 , and the stirring shaft 17 is rotatably connected to the liquid storage barrel 3 , and a plurality of stirring rods 18 are fixedly mounted on the outer side of the stirring shaft 17 .

[0032] The stirring rod 18 in the stirring mechanism can stir the stock solution to avoid static sedimentation and stratification, and at the same time make the stock solution evenly mixed to avoid inconsistent color of the stock solution on the tablets.

[0033] The mounting seat 8 is conical in shape, and the tip of the cone points to the opening of the coating pan 4 .

[0034] Since the coating pan 4 is installed at an angle, one end of the mounting seat 8 is tapered, thereby preventing the tablets from staying outside the mounting seat 8 during discharge.

[0035] The pitch circle diameter length of the driving gear 13 is smaller than the pitch circle diameter length of the driven gear 14 .

[0036] The transmission ratio is then increased, causing the driven gear 14 to rotate slowly, and thus the turntable 12 to rotate slowly.

[0037] The second motor 16 is fixedly mounted on the top surface of the liquid storage barrel 3 , and the output shaft of the first motor 15 passes through the top surface of the liquid storage barrel 3 and is connected to the stirring shaft 17 .

[0038] The first motor 15 provides a driving source for the stirring shaft 17 .

[0039] Two infrared heating plates 5 are symmetrically installed on the outside of the control box 2, and a discharge pipe 6 is fixed and connected to the outside of the coating pot 4.

[0040] The coating pot 4 can be heated by the infrared heating plate 5 to facilitate drying of the coated tablets.

[0041] When the utility model is used, first, the tablets are placed into the coating pot 4 through the opening of the coating pot 4, and then the first motor 15 is started, and the driving gear 13 is engaged with the driven gear 14, thereby driving the turntable 12 to rotate, and the inclined plates 10 installed on the sides of the multiple connecting rods 9 are used to support the tablets, thereby driving the tablets in the coating pot 4 to move upward along the inner wall of the coating pot 4. After reaching a certain angle, the tablets will slide down from the inclined plates 10 in sequence, thereby forming a thin waterfall shape;

[0042] At the same time, the second motor 16 is started to drive the stirring shaft 17 to rotate, thereby stirring the original liquid in the liquid storage barrel 3 through the stirring rod 18 to mix it evenly and avoid static sedimentation and stratification. Then, the original liquid in the liquid storage barrel 3 is extracted by the water pump 19, enters the liquid inlet pipe 7 through the connecting pipe 20, and is atomized and sprayed on the falling tablets through the atomizing nozzle 11. At the same time, the multiple inclined plates 10 rotate, so that the tablets are sprayed evenly in turn, so that each tablet is fully coated;

[0043] After the coating is completed, the coating pot 4 is heated and dried by the infrared heating plate 5, and the tablets are discharged through the discharge pipe 6.

[0044] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
