Description

Technical Field

[0001] The utility model relates to the technical field of stirring devices, in particular to a raw material stirring device for compressed biscuit production. Background Art

[0002] Compressed biscuits are a kind of convenient food. They are made of wheat flour, sugar, oil, and dairy products as the main raw materials. They are mixed with cold powder, rolled, baked, cooled, crushed, and mixed. Other dried fruits, meat floss and other auxiliary materials can be added, and then compressed to form biscuits. There are many kinds of compressed biscuits on the market, including anti-radiation compressed biscuits. The so-called anti-radiation compressed biscuits are anti-radiation products derived from air radiation, electronic product radiation, ionizing radiation, and nuclear radiation in future wars. Spirulina and kelp powder are added to anti-radiation compressed dry food. These two products have anti-radiation functions. In the production and processing of anti-radiation compressed biscuits, a stirring device is needed to stir them evenly. However, the existing stirring device has a simple structure and low efficiency in mixing raw materials.

[0003] The technical solution disclosed in the Chinese patent with authorization announcement number CN220091090U drives the hanger to rotate through a servo motor, and at the same time drives the stirring shaft to rotate to drive the stirring rod for stirring. First, sugar water, hot water and oil are added from the No. 2 feeding port, and then biscuit crumbs are added from the No. 1 feeding port. When the hanger is running, it will drive the magnetic block 2 to rotate periodically. When it moves to the position of magnetic block 1, the principle of like charges repel each other is used to make the magnetic block 1 drop and drive the other end of the balance plate to rise, further drive the push rod to rise, further press the pressure plate to move up, press the pressure sensor, and send an electrical signal to the controller. The controller controls the cylinder to move periodically once, driving the push block to push a certain amount of biscuit crumbs into the agitator for stirring. After the magnetic block 2 is removed, the slider is driven to drop and reset under the action of the spring, and further drives the pressure plate to return to the starting position to form a cycle. The biscuit crumbs are added periodically for stirring, and the mixing effect is better, which is practical.

[0004] However, the device still has some shortcomings: the mixing efficiency between the bottom layer raw materials and the upper layer raw materials in the device is low and takes a long time, so that the mixing of the raw materials requires more electric energy. Utility Model Content

The frame 1 is rotatably connected to a stirring barrel, and a feeding pipe 5 and a discharging pipe 6 communicating with the inside of the stirring barrel are arranged on the stirring barrel, and a valve for opening and closing the internal passage thereof is arranged in the discharging pipe 6. The stirring barrel comprises a barrel body 2 and an end cover 4, the end cover 4 is sealed and fitted with the opening edge of the barrel body 2, and a fixing ring 3 is sleeved on the outside of the barrel body 2, and two mounting shafts are symmetrically arranged on the fixing ring 3 about the central axis of the barrel body 2, and the mounting shafts on both sides are rotatably connected to the corresponding ends of the frame 1 respectively. A feeding hole is arranged on the barrel body 2, and a feeding pipe 5 is connected to the barrel body 2 and communicated with the feeding hole. A discharging hole communicating with the inside of the barrel body 2 is arranged on the end cover 4, and the lower edge of the discharging hole is fitted with the lower edge of the inner cavity of the barrel body 2, and the discharging pipe 6 is connected to the end of the end cover 4 away from the barrel body 2 and covered on the outside of the discharging hole. The stirring mechanism is located in the stirring barrel, and the stirring mechanism includes a main shaft 7, a motor 8, a secondary shaft 11 and a transmission assembly. The main shaft 7 is located in the barrel body 2 and is rotatably connected to the end of the barrel body 2 and the end cover 4. The main shaft 7 is coaxial with the end cover 4, and a plurality of connecting frames 9 are arranged on the main shaft 7. The connecting frame is a bracket with multiple supporting feet, and each group of supporting feet is respectively connected to a scraper 10. The scraper 10 is slidably connected to the inner wall of the barrel body 2, and the two ends of the scraper 10 are respectively slidably connected to the side wall of the inner cavity of the barrel body 2 and the end surface of the end cover 4. The motor 8 is connected to the outer end surface of the barrel body 2, and the output end of the motor 8 is connected to the end of the main shaft 7. The secondary shaft 11 is rotatably connected to the connecting frame 9 and is parallel to the main shaft 7. A plurality of stirring paddles 12 are arranged on the secondary shaft 11. The secondary shaft 11 is connected to the main shaft 7 through the transmission assembly, so that the secondary shaft 11 is driven to rotate while the main shaft 7 drives the secondary shaft 11 to revolve around the main shaft 7. The transmission assembly includes an outer gear ring 402 and a gear 13. An annular groove 401 coaxial with the barrel body 2 is provided on the side of the end cover 4 facing the barrel body 2, an outer gear ring 402 is located in the annular groove 401 and connected to the end cover 4, a gear 13 is connected to the secondary shaft 11, and the gear 13 is inserted into the annular groove 401 and meshed with the outer gear ring 402. The stirring mechanism stirs the raw materials in the mixing barrel in a working state, and shakes the raw materials after being stirred and lifted. The swing drive assembly includes a first hydraulic cylinder 14, the cylinder barrel of the first hydraulic cylinder 14 and the end of the push rod away from each other are respectively rotatably connected to a group of ear plates, and the two groups of ear plates are respectively rotatably connected to the frame 1 and the mixing barrel, and the swing drive assembly connects the frame 1 and the mixing barrel, and the swing drive assembly drives the mixing barrel to swing around the adapter between it and the frame 1 in a working state.

[0025] In this embodiment, the motor 8 is started, and the motor 8 drives the main shaft 7 to rotate, thereby driving the connecting member 9 and the scraper 10 to rotate. In the process of driving the connecting frame 9 to rotate, the main shaft 7 also drives the secondary shaft 11 to revolve around the main shaft 7. The secondary shaft 11 itself rotates at a relatively high speed under the transmission action of the gear 13 and the outer gear ring 402. At this time, raw materials are added into the barrel body 2 along the feed pipe 5. Driven by the scraper 10, the raw materials are gradually lifted along the inner wall of the barrel body 2.
