Description

Technical Field

[0001] The present application relates to the technical field of granule medicine production, and in particular to a slurry feeding mechanism for granule medicine production. Background Art

[0002] The equipment commonly used in the granulation production process of granular drugs is the spray granulator. Its working principle is to first spray the slurry drug to be processed from the top of the spray granulator into the inside of the granulator tank, and then send the dry and heated air or nitrogen to the bottom of the granulator tank through a pipe. During the rising process, the hot air comes into contact with the slurry particles, absorbs the moisture in the slurry, and is discharged from the top of the granulator tank. The slurry is dehydrated and dried to become granules.

[0003] The patent application with application number CN202320936715.2 discloses a slurry feeding mechanism for the production of granular medicines, including a reduction motor; the output shaft of the reduction motor is connected to a turntable, a bar guide rail is installed on the turntable, and a slider is slidably connected to the inner side of the bar guide rail, and an electric lift is provided on the inner side of the bar guide rail, and the power output end of the electric lift is connected to the slider. The slurry feeding mechanism for the production of granular medicines can raise the raw material barrel to the top of the spray granulator for unloading, effectively avoiding the cleaning difficulties and material sedimentation problems caused by the long feeding pipeline, and at the same time can make the particle size produced by the spray granulator more uniform; the reduction motor is installed on the ground or in an equipment pit on the ground, and the reduction motor can drive the raw material barrel to rotate, so that the raw material barrel can be easily rotated and adjusted, which is convenient for loading and unloading of the slurry; the raw material barrel can be raised to a high unloading station by the electric lift.

[0004] Although the above patent avoids the problems of difficult cleaning and material sedimentation caused by the excessively long feeding pipeline, when adding materials to the raw material barrel, the raw material barrel needs to be lowered, filled with slurry, and then raised, which is very inconvenient. Utility Model Content

[0005] In order to make it more convenient to add raw materials into a raw material barrel, the present application provides a slurry feeding mechanism for the production of granular medicines.

[0006] The above technical objectives of this application are achieved through the following technical solutions:

[0007] A slurry feeding mechanism for producing granular medicines comprises a bracket, a raw material pool is arranged below the bracket, a raw material barrel is arranged above the bracket, the bracket is connected to a lifting structure, the lifting structure is connected to a pouring barrel, and the pouring barrel is connected to a pouring structure for controlling the pouring barrel to pour the raw materials into the raw material barrel.

[0008] By adopting the above scheme, when it is necessary to pour raw materials into the raw material barrel, the pouring barrel is filled with raw materials in the raw material pool, and then the lifting structure raises the pouring barrel to above the raw material barrel, and then the pouring structure pours the raw materials in the raw material barrel into the raw material barrel, thereby realizing automatic addition of raw materials in the raw material barrel.

[0010] By adopting the above technical solution, the driving motor drives the active pulley to rotate, and the active pulley drives the conveyor belt to rotate, thereby driving the pouring bucket to move. When the pouring bucket pours the raw materials into the raw material barrel, the pouring bucket can continue to move with the conveyor belt, so that the pouring bucket returns to the initial position. Therefore, multiple pouring buckets can be set to move continuously at the same time.

[0011] The cam is provided with two cams, and the cam is connected with the bottom plate of the conveyor belt support, and the cam is connected with the bottom plate of the conveyor belt support, and the cam is connected with the bottom plate of the conveyor belt support, and the cam is connected with the bottom plate of the conveyor belt support, and the cam is connected with the bottom plate of the conveyor belt support, and the cam is connected with the bottom plate of the conveyor belt support, and the cam is connected with the bottom plate of the conveyor belt support, and the cam is connected with the bottom plate of the conveyor belt support.

[0012] By adopting the above technical solution, after the pouring barrel is replenished with raw materials in the raw material pool, it moves with the conveyor belt until the pouring barrel reaches the position of the slide bar, and the slide bar slides into the slide groove, thereby driving the guide plate to move away from the side plate, thereby driving the pin to slide out of the card slot, and the pouring barrel may be tilted by gravity at any time, thereby pouring the raw materials into the raw material barrel, thereby completing the automatic filling of the raw materials into the raw material barrel.

[0013] Optionally, the end of the latch facing away from the spring is inclined, and the inclined surface faces away from the bottom plate.

[0014] By adopting the above technical solution, when the pouring barrel starts to move downward, the pouring barrel rotates around the hinge axis due to the influence of gravity, so that the pouring barrel contacts the inclined surface of the pin and presses the pin into the pin groove until the pin is opposite to the slot. The pin is then inserted into the slot, thereby fixing the pouring barrel, allowing the pouring barrel to be filled with raw materials in the raw material pool again, and cyclically pouring the raw materials into the raw material barrel.

[0015] Optionally, the raw material barrel is rectangular.

[0016] By adopting the above technical solution, the rectangular raw material barrel can increase the area that can receive the raw materials, so that it is smoother to fill the raw materials into the raw material barrel by pouring the material barrel.

[0017] Optionally, a stirring structure is provided in the raw material barrel.

[0018] By adopting the above technical solution, a stirring structure is provided to stir the raw materials in the raw material barrel, thereby preventing the raw materials from settling and causing uneven production of granular drugs.

[0019] Optionally, the stirring structure includes a stirring rod, which is rotatably connected to the raw material barrel, and one end of the stirring rod penetrates the raw material barrel and is connected to a stirring motor.

[0020] By adopting the above technical solution, the stirring motor drives the stirring rod to rotate, thereby stirring the raw materials in the raw material barrel, thereby realizing automatic stirring of the raw materials.

[0021] Optionally, a sealing ring is provided at the location where the stirring rod penetrates the raw material barrel.

[0022] By adopting the above technical solution, the raw materials are prevented from flowing out at the point where the stirring rod penetrates the raw material barrel.

[0023] In summary, this application has the following technical effects:

[0024] 1. The lifting structure and the pouring structure make it more convenient to fill the raw materials in the raw material barrel;

[0025] 2. The material dumping barrel is driven up and down by setting a driving pulley, a driven pulley and a conveyor belt;

[0026] 3. A stirring mechanism is provided to stir the raw materials in the raw material barrel, thereby preventing the raw materials in the raw material barrel from settling. BRIEF DESCRIPTION OF THE DRAWINGS

The conveyor belt 43 is sleeved on the outer side of the driving pulley 41 and the driven pulley, and the driving pulley 41 and the driven pulley 42 tighten the conveyor belt 43. Cover plates 431 are arranged on opposite sides of the conveyor belt, and the cover plates 431 are fixedly connected to the bracket 1. A plurality of pouring buckets 5 and pouring structures 6 are arranged, and a plurality of pouring structures 6 and pouring buckets 5 are evenly arranged on the outer surface of the conveyor belt 43. The driving motor 411 drives the active pulley 41 to rotate, and the active pulley 41 drives the conveyor belt 43 to move, thereby driving the driven pulley 42 to rotate, and the conveyor belt 43 drives the pouring barrel 5 to move upward, and then the pouring barrel 5 pours the raw material into the raw material barrel 3, and then the conveyor belt 43 drives the pouring barrel 5 to move downward, so that the pouring barrel 5 returns to its original position, so that the pouring barrel 5 can be recycled, and multiple pouring barrels 5 are set at the same time to increase the filling speed of the raw material barrel 3 with raw materials.

[0036] Reference Figure 2 and Figure 3 The pouring structure 6 includes a bottom plate 61 and a side plate 62. The bottom plate 61 is fixedly arranged on the outer surface of the conveyor belt 43. The bottom of one side surface of the pouring barrel 5 is hinged to the bottom plate 61. Two side plates 62 are provided. The two side plates 62 are respectively arranged on opposite sides of the adjacent side of the pouring barrel 5 and the bottom plate 61, and the side plates 62 are fixedly connected to the bottom plate 61. The pouring barrel 5 is provided with a card slot 51 on both sides near the side plate 62. The side plate 62 is provided with a pin slot 621 at the position opposite to the card slot 51. A card pin 622 is slidably connected in the pin slot 621. In the initial state, part of the card pin 622 is located in the pin slot 621, and the other part is located in the card slot 51, so as to fix the pouring plate. When the card pin 622 is located at one end of the card slot 51, it is inclined, and the inclined surface faces the side away from the bottom plate 61. A spring 624 is provided in the pin slot 621 , one end of the spring 624 is fixedly connected to the bayonet 622 , and the other end of the spring 624 is fixedly connected to the side plate 62 . When the spring 624 is at its original length, part of the bayonet 622 is located in the bayonet slot 51 , and the other part is located in the pin slot 621 .

[0037] Reference Figure 1-4The latch 622 is located in the pin groove 621 and is fixedly connected to a connecting rod 623 on one side. The connecting rod 623 penetrates the side plate 62 at one end away from the latch 622, and the connecting rod 623 is slidably connected to the side plate 62. A guide plate is fixedly connected to the end of the connecting rod 623 passing through the side plate 62. An inclined slide groove 6251 is provided on the side of the guide plate close to the conveyor belt 43. The cover plate 431 is fixedly connected to a slide rod 626, and the slide rod 626 is arranged at a position where the cover plate 431 is located above the raw material barrel 3. When the guide plate 625 passes the slide rod 626, the slide rod 626 slides into the slide groove 6251, and the sliding cover drives the guide plate 625 to move away from the side plate 62. The material barrel 5 moves to the right, thereby driving the latch 622 to slide out of the latch slot 51, and then the pouring barrel 5 is tilted by gravity, thereby pouring the raw materials in the pouring barrel 5 into the raw material barrel 3. After the pouring is completed, the pouring barrel 5 continues to move with the conveyor belt 43, and then the pouring barrel 5 moves downward. The pouring barrel 5 rotates around the hinge shaft under the influence of gravity, so that the pouring barrel 5 contacts the inclined surface of the latch 622, and the latch 622 is completely pressed into the pin slot 621 until the pin slot 621 is opposite to the latch slot 51.

One end of the stirring rod 71 penetrates the raw material barrel 3 and is fixedly connected with the stirring motor 72. The stirring motor 72 is fixedly connected with the bracket 1. A sealing ring 711 for sealing is arranged at the place where the stirring rod 71 penetrates the raw material barrel 3. The stirring motor 72 drives the stirring rod 71 to rotate, thereby stirring the raw materials in the raw material barrel 3 to prevent the raw materials from settling.

[0039] The specific implementation principle of the present application is as follows: the driving motor 411 drives the active pulley 41 to rotate, thereby driving the conveyor belt 43 to move, and the pouring bucket 5 moves upward with the conveyor belt 43 after replenishing the raw materials in the raw material pool 2, until the pouring bucket 5 reaches the position of the slide bar 626, and the slide bar 626 slides into the slide groove 6251, thereby driving the guide plate 625 to move away from the side plate 62, thereby driving the latch to slide out of the card slot 51, and the pouring bucket 5 is tilted by gravity at any time, thereby pouring the raw materials into the raw material barrel 3, and The rear pouring barrel 5 continues to move with the conveyor belt 43. When the pouring barrel 5 moves downward, the pouring barrel 5 rotates around the hinge shaft due to the influence of gravity, so that the pouring barrel 5 contacts the inclined surface of the latch 622 and presses the latch 622 into the pin groove 621 until the latch 622 is opposite to the latch groove 51. Then the latch 622 is inserted into the latch groove 51, thereby fixing the pouring barrel 5, so that the pouring barrel 5 can be filled with raw materials in the raw material pool 2 again, and the raw materials are circulated and poured into the raw material barrel 3, thereby cyclically adding raw materials to the raw material barrel 3.
