DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Example 1

[0022] refer to Figures 1 to 7 , a shot making device, comprising a shot blasting mechanism 1, a heat drying mechanism 2, the heat drying mechanism 2 is provided with a feed pipe 213 and a discharge pipe 214, the feed pipe 213 is connected to the output end 121 of the shot blasting mechanism 1, and also comprises a heat absorption component 3 and an exhaust mechanism 4, the heat absorption component 3 is installed on both sides of the heat drying mechanism 2, one end of the exhaust mechanism 4 is connected to the heat absorption component 3, and the other end is connected to the shot blasting mechanism 1;

[0023] The heat absorption component 3 is used to absorb the heat from the side of the heat drying mechanism 2 and transport the heat to the shot blasting mechanism 1 through the exhaust mechanism 4.

[0024] Under this design, the operator puts the medicinal materials into the shot blasting mechanism 1, and the shot blasting mechanism 1 drives the medicinal materials to make circular motion by rotating, so that the medicinal materials collide with the inner wall of the shot blasting mechanism 1, and the medicinal materials are processed into spherical shapes. The spherical medicinal materials are referred to as pills below. After processing, the pills are transported to the hot drying mechanism 2 for drying. The hot drying mechanism 2 will also increase the temperature of the hot drying mechanism 2 itself during the drying process. By installing heat absorption components 3 on both sides of the hot drying mechanism 2, the heat from the two sides of the hot drying mechanism 2 can be absorbed, and then the heat is transported to the shot blasting mechanism 1 through the exhaust mechanism 4. After these hot air contacts with the medicinal materials, they will soften the pills to a certain extent, because the surface temperature of the pills will not be very high, and there will be heat loss during the transportation process, so these hot air will only have a slight softening effect and will not melt the pills.

[0025] In this way, the medicinal material can be softened without setting up an additional heating device, so that the medicinal material can be more easily processed into spherical pills by the shot blasting mechanism 1, which helps to improve the molding effect.

[0026] Preferably, the heat absorption component 3 includes heat-insulating cotton 31 and a mounting frame 32 . The heat-insulating cotton 31 is installed on two sides of the heat drying mechanism 2 through the mounting frame 32 , and the exhaust mechanism 4 is connected to the mounting frame 32 .

[0027] Specifically, the thermal insulation cotton 31 is installed on the two sides of the heat drying mechanism 2 through the mounting frame 32, and is in contact with the sides of the heat drying mechanism 2 to ensure that the temperature is transferred to the thermal insulation cotton 31. The exhaust mechanism 4 will allow the outside air to enter the exhaust mechanism 4 through the thermal insulation cotton 31, and take away the heat in the thermal insulation cotton 31, thereby realizing heat transportation, avoiding heat waste, and saving more energy.

[0028] In this embodiment, the exhaust mechanism 4 includes a main pipe 41, a plurality of branch pipes 42 located on the main pipe 41, and an exhaust fan 43 connected to the main pipe 41, one end of the branch pipe 42 is connected to the mounting frame 32, and one end of the main pipe 41 is connected to the shot blasting mechanism 1.

[0029] The exhaust fan 43 will draw the outside air into the branch pipe 42 through the insulation cotton 31, and then transport it to the main pipe 41 through the branch pipe 42, and then transport it to the shot blasting mechanism 1 from the main pipe 41. During the transportation process, heat will be lost in the main pipe 41 and the branch pipe 42, while it can also ensure that the heat entering the shot blasting mechanism 1 will not be too high.

[0030] In this embodiment, the shot blasting mechanism 1 includes a support frame 11, an outer shell 12 connected to the support frame 11, a turntable 13 rotatably connected to the outer shell 12, and a driving motor (not shown in the figure) for driving the turntable 13 to rotate. An output terminal 121 is provided on the side of the outer shell 12, one end of the main pipe 41 is connected to the side of the outer shell 12, and a grid plate 411 is provided at one end of the main pipe 41.

[0031] In actual use, the support frame 11 is only used for supporting and elevating the outer shell 12, the turntable 13, and the drive motor, and the outer shell 12, the turntable 13, and the drive motor are the shot blasting machine. Specifically, the turntable 13 is driven by the drive motor to rotate, so that the medicinal materials on the turntable 13 are constantly moving and collide with the inner wall of the outer shell 12, so as to achieve the purpose of processing into a spherical shape. The hot air input through the main pipe 41 can soften the medicinal materials, so that it is easier to process into a spherical shape. The grid plate 411 can prevent the medicinal materials from entering the main pipe 41.

[0032] Preferably, the heat drying mechanism 2 includes a pill conveying bin 21, a hot air conveying unit 22 connected to the bottom of the pill conveying bin 21, the feed pipe 213 and the discharge pipe 214 are located on the pill conveying bin 21, and the heat absorption component 3 is installed on both sides of the pill conveying bin 21.

[0033] During the processing, the processed pills enter the pill conveying bin 21 from the feed pipe 213, are supported by the pill conveying bin 21 and conveyed to the discharge pipe 214. During the conveying process, the hot air conveying unit 22 will continuously convey hot air into the pill conveying bin 21 to dry the pills in the pill conveying bin 21. Since the hot air is uncontrollable in the pill conveying bin 21, the hot air will also heat the pill conveying bin 21, causing the temperature of the outer side of the pill conveying bin 21 to increase.

[0034] In this embodiment, the pill conveying bin 21 includes a bin body 211 and a conveying plate 212 located in the bin body 211. The feed pipe 213 and the discharge pipe 214 are located on the bin body 211. The conveying plate 212 is provided with a plurality of protrusions 2121 protruding along its surface. The side of the protrusion 2121 is provided with a channel 21213 penetrating the bottom of the conveying plate 212. The heat absorption component 3 is installed on both sides of the bin body 211, and the hot air conveying unit 22 is connected to the bottom of the bin body 211.

[0035] Specifically, after the hot air is conveyed into the bin body 211, it enters into the channel 21213 through the bottom of the conveying plate 212 and is output from the side of the convex portion 2121, so the output of the hot air is horizontal, which can provide power for the pills. The pills on the conveying plate 212 are subjected to the horizontal thrust of the hot air and will continue to move toward the discharge pipe 214. In the process of moving and tumbling, the drying is more uniform.

[0036] Preferably, the convex portion 2121 includes a first convex block 21211 and a second convex block 21212, the first convex block 21211 and the second convex block 21212 are arranged in an array along the length direction of the conveying plate 212, the output end of the channel 21213 is located on the sides of the first convex block 21211 and the second convex block 21212, the first convex block 21211 and the second convex block 21212 are both hemispherical crown structures, and along the conveying direction of the conveying plate 212, the first convex block 21211 and the second convex block 21212 are alternately arranged; in the vertical plane projection along the conveying direction of the conveying plate 212, the second convex block 21212 is located between the two first convex blocks 21211.

[0037] We found that although conveying can be achieved if only the first protrusions 21211 are used, since the first protrusions 21211 are arranged in an array, there will be intervals between the first protrusions 21211 along the length direction of the conveying plate 212, and the smoothness of the pills moving in this interval is poor. Therefore, in order to further optimize the conveying smoothness of the conveying plate 212, a second protrusion 21212 that is exactly the same as the first protrusion 21211 is added, and in the conveying direction of the conveying plate 212, the first protrusions 21211 and the second protrusions 21212 are alternately arranged; in the vertical plane projection along the conveying direction of the conveying plate 212, the second protrusion 21212 is located between the two first protrusions 21211, which can well make up for the intervals between the first protrusions 21211, make the conveying smoother, and avoid the problem of pills getting stuck.

[0038] More preferably, an exhaust duct 215 is provided on the top of the warehouse body 211. The moisture and heat generated during the drying process need to be removed in time to maintain ventilation and air exchange in the drying room, prevent moisture from being retained in the room, and affect the drying effect and product quality; the exhaust duct 215 can effectively discharge moisture and heat to the outside, maintain the dry environment in the drying room, and improve the drying efficiency and product quality; although the hot air will be discharged during the drying process, the exhaust duct 215 still needs to be provided to ensure the circulation of indoor air and the drying effect.

[0039] Moreover, the hot air in the exhaust pipe 215 has many impurities in the gas because of the drying effect. If the hot air with impurities is passed into the shot blasting machine, it will contaminate the medicinal materials.

[0040] Optionally, a discharge plate 216 connected to the conveying plate 212 is further provided in the silo 211, and the discharge plate 216 is arranged at an angle, and is used to guide the pills on the conveying plate 212 to the discharge pipe 214. In order to ensure the smooth discharge of the pills, the discharge plate 216 connected to the conveying plate 212 is provided in the silo 211, and the discharge plate 216 is arranged at an angle, so that the dried pills can fall along the inclination of the discharge plate 216.

[0041] The hot air delivery unit 22 includes a hot air output mechanism (not shown in the figure), a delivery pipe 221 connected to the hot air output mechanism, and multiple hot air output pipes 222 connected to the delivery pipe 221. The hot air output pipe 222 is connected to the bottom of the warehouse body 211, and a control valve 2221 is provided on the hot air output pipe 222.

[0042] Specifically, when in use, the hot air conveying mechanism conveys the hot air into the conveying pipe 221, and then outputs the hot air from the hot air output pipe 222 through the conveying pipe 221, and delivers the hot air into the warehouse body 211. It should also be noted here that during the conveying process, the hot air needs to be pressurized so that the output hot air can drive the movement of the pills.

[0043] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
