Description

Technical Field

[0001] The utility model belongs to the technical field of quick-freezing equipment, and particularly relates to a quick-freezing device for steamed buns. Background Art

[0002] A quick-freezing machine is a high-efficiency freezing device that can freeze a large number of products in a short time. It consists of a refrigeration system, a propulsion system, an electrical control system, a quick-freezing chamber, etc.; Workers form a stable vertical annular low-temperature air flow through the action of a deflector plate on the frozen product tray filled with food to be frozen, and this low-temperature air flow exchanges heat with the frozen food moving horizontally, thereby realizing the rapid cooling and freezing process.

[0003] During the production and processing of instant steamed buns, the steamed buns need to be quick-frozen before packaging. The conveyor belt of the quick-freezing machine, as the transmission mechanism of the quick-freezing machine, plays a crucial role in the conveying process. There will be a certain amount of water residue on the skin of the steamed buns, and the water inside the steamed buns will also volatilize outward during the quick-freezing process and condense when cooled. Therefore, due to the water on the skin, the steamed buns will stick to the conveyor belt during the quick-freezing process, which makes it difficult to take the quick-frozen steamed buns from the conveyor belt, reduces the work efficiency, and increases the risk of the steamed bun skin cracking during taking, affecting the quality of the steamed buns.

[0004] Therefore, the applicant has carried out beneficial exploration and attempts and found a solution to the above problems. The technical solution to be introduced below was generated under this background. Summary of the Utility Model

Detailed implementation mode

[0020] The following is through examples and in combination with the attached Figures 1-4 As shown in the structure, the technical solution of the present utility model will be further specifically described.

[0021] Example: A quick-freezing device for small steamed buns includes a quick-freezing machine 1 and a box body 2. Support rods 3 are fixedly arranged around the bottom of the box body 2. There is an opening at the top of the box body 2. The quick-freezing machine 1 is fixed at the bottom of the box body 2 and communicates with the box body 2 through the opening at the top of the box body 2. A conveyor belt 4 and a transmission belt 5 are installed inside the box body 2. The conveyor belt 4 is a mesh plate conveyor belt. The transmission belt 5 is located above the conveyor belt 4. A plurality of scrapers 6 are fixedly arranged at equal intervals on the transmission belt 5. The scraper 6 is made of a low-temperature flexible rubber material, so as to ensure that the scraper 6 remains flexible at low temperatures, thereby avoiding damaging the small steamed buns during use. A power mechanism is fixedly arranged on the outer wall of one side of the box body 2 and at one end. A first synchronous belt 7 is arranged between the power mechanism and the transmission belt 5 inside the box body 2. The diameters of the two pulleys of the first synchronous belt 7 are different. The diameter of the pulley installed on the power mechanism is larger than the diameter of the pulley installed on the transmission belt 5, so that the transmission speed of the transmission belt 5 is higher than that of the conveyor belt 4, so as to achieve that the scraper 6 can stir the small steamed buns during use and reduce the probability of the small steamed buns sticking to the conveyor belt 4. A vibration mechanism is also arranged on the box body 2. A second synchronous belt 8 is arranged between the vibration mechanism and the power mechanism. The diameters of the two pulleys of the second synchronous belt 8 are the same. The vibration mechanism is located inside the conveyor belt 4 and close to the upper part of the conveyor belt 4.

[0022] The vibration mechanism includes a reset component, a rotating shaft 11, a vibration rod 12, and an eccentric cam 13. Rectangular slots 14 are symmetrically formed on both side walls of the box body 2. The reset components are symmetrically installed in the two rectangular slots 14. The rotating shaft 11 is rotatably installed between the two side walls of the box body 2 and is located below the two rectangular slots 14. Eccentric cams 13 are symmetrically fixed at both ends of the rotating shaft 11. The reset component includes a slide rod 15, a slider 16, and a spring 17. The slide rod 15 is vertically fixed in the rectangular slot 14. The slider 16 is slidably installed on the slide rod 15. A convex block 18 is fixed on the side of the slider 16 facing the outside of the box body 2. An arc surface capable of cooperating with the eccentric cam 13 is provided at the bottom of the convex block 18. The vibration rod 12 is fixed between the sliders 16 of the two groups of reset components. The spring 17 is sleeved on the slide rod 15 and its two ends are respectively fixedly connected to the bottom of the slider 16 and the bottom of the rectangular slot 14. The spring 17 is a tension spring. During use, the rotation of the eccentric cam 13 and the cooperation of the tension spring can repeatedly lift the slider 16 so that the vibration rod 12 can intermittently lift the conveyor belt 4 to generate vibration, and cooperating with the scraper 6 can prevent the small steamed buns from sticking to the conveyor belt 4.

[0023] The power mechanism includes a gearbox 9 and a motor 10. The gearbox 9 is fixed at one end of an outer wall of the box body 2. The motor 10 is fixed on the gearbox 9. The end of the output shaft of the motor 10 is coaxially fixed to the input end of the gearbox 9. The output end of the gearbox 9 is fixedly connected to one end of the conveyor belt 4. The two pulleys of the first synchronous belt 7 are respectively installed on the output end of the gearbox 9 and one end of the transmission belt 5. The two pulleys of the second synchronous belt 8 are respectively installed on the output shaft of the motor 10 and one end of the rotating shaft 11.

[0024] The working principle of the present utility model:

[0025] During use, the operator first starts the quick-freezing machine 1 to pre-cool the inside of the box body 2, and then starts the motor 10. The motor 10 drives the conveyor belt 4 through the gearbox 9. Driven by the first synchronous belt 7 and the second synchronous belt 8, the transmission belt 5 and the vibration mechanism are started simultaneously. The operator places the small steamed buns to be quick-frozen on one end of the conveyor belt 4. The conveyor belt 4 sends the small steamed buns into the box body 2 for freezing. Since the diameters of the two pulleys of the first synchronous belt 7 are different, the running speeds of the transmission belt 5 and the conveyor belt 4 are different, so that the scraper 6 on the transmission belt 5 can stir the small steamed buns. One end of the second synchronous belt 8 is directly connected to the output shaft of the motor 10, so it can drive the eccentric cam 13 to rotate at a high speed. The rotation of the eccentric cam 13 and the cooperation of the tension spring 17 can repeatedly lift the slider 16 so that the vibration rod 12 can intermittently lift the conveyor belt 4 to generate vibration, and cooperating with the scraper 6 can prevent the small steamed buns from sticking to the conveyor belt 4.

[0026] Finally, it should be noted that the above embodiments are only relatively representative examples of the present utility model. Obviously, the present utility model is not limited to the above embodiments and there can be many variations. Any simple modification, equivalent change, and modification made to the above embodiments based on the technical essence of the present utility model shall be considered to fall within the protection scope of the present utility model.
