Abstract
Description
Technical Field
[0001] This utility model relates to the field of powdering device technology, specifically to an automatic powdering device for pastry production. Background Technology
[0002] In the pastry making process, many pastries need to be sprinkled with powdered materials such as powdered sugar and flour on the surface. This layer of flour can prevent the surface of the pastry from browning too much during baking, and at the same time make the pastry look whiter and more beautiful. Automatic powdering devices can precisely control the amount and evenness of powdering, ensuring that each pastry is properly treated and avoiding situations where some pastries are too dark or have no powder in some places due to uneven powdering by manual methods.
[0003] The existing technology has the following problems:
[0004] The existing equipment cannot vibrate the powdering plate simultaneously in all directions. Without omnidirectional vibration, the powder distribution on the powdering plate is prone to unevenness. The powder may not be fully dispersed, resulting in local accumulation and ineffective dispersion to all parts of the pastry surface, affecting the taste and appearance. In addition, the existing equipment cannot pre-screen the raw materials. The raw material powder may contain particles of different sizes. When powder is sprinkled directly without screening, coarse particles will settle first due to gravity, while fine powder will settle later, resulting in "particle accumulation" or "insufficient powder" on the surface of the pastry. Utility Model Content

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0023] To make the technical means, creative features, objectives, and effects of this utility model easier to understand, the following describes this utility model in conjunction with specific embodiments:
[0024] like Figure 1 As shown, this utility model provides an automatic powder-sprinkling device for pastry production, including a base 1, a conveying mechanism 4 fixedly connected to the upper side of the base 1, multiple support legs 2 fixedly connected to the upper side of the base 1, a fixed box 3 fixedly connected to the upper end of the support legs 2, a movable frame 5 slidably connected to the upper side of the fixed box 3, a storage tank 6 fixedly connected to the upper side of the movable frame 5, and a discharge pipe 7 fixedly connected to the lower side of the storage tank 6. The entire device is supported by the base 1. The conveying mechanism 4 is responsible for conveying the pastries to be powdered. The support legs 2 fixedly support the fixed box 3. The movable frame 5 can slide and adjust its position on the fixed box 3. The storage tank 6 is used to store powder raw materials. The raw materials are conveyed to the powder-sprinkling plate 10 through the discharge pipe 7, and finally the powder-sprinkling operation on the pastries on the conveying mechanism 4 is completed. The sliding design of the movable frame 5 can flexibly adjust the relative position of the storage tank 6 and the powder-sprinkling plate 10 to adapt to the powder-sprinkling needs of pastries of different sizes.
[0025] like Figure 2-4As shown, this utility model provides a technical solution: Preferably, an electric telescopic rod 11 is fixedly connected to the rear side of the fixed box 3, a movable block 12 is fixedly connected to the output end of the electric telescopic rod 11, a powder-spreading plate 10 is slidably connected to the front side of the movable block 12, support plates 9 are fixedly connected to both the left and right sides of the powder-spreading plate 10, sliding grooves 8 are provided on both the left and right sides of the fixed box 3, the outer wall of the support plate 9 is movably connected to the sliding groove 8, two guide posts 13 are fixedly connected to the right side of the inner surface of the fixed box 3, two inclined blocks 14 are fixedly connected to the upper side of the powder-spreading plate 10, the outer wall of the guide posts 13 is movably connected to the inclined blocks 14, a limiting block 16 is fixedly connected to the front side of the movable block 12, a limiting groove 15 is provided on the rear side of the powder-spreading plate 10, the outer wall of the limiting block 16 is slidably connected to the limiting groove 15, and a limiting rod 17 is fixedly connected to the inner surface of the limiting groove 15. The outer wall of the limiting rod 17 is slidably connected to the limiting block 16. Two springs 18 are sleeved on the outer wall of the limiting rod 17. One end of the spring 18 is fixedly connected to the powder spreading plate 10, and the other end of the spring 18 is fixedly connected to the limiting block 16. When the electric telescopic rod 11 extends and retracts, it drives the movable block 12 to move back and forth. The movable block 12 is slidably connected to the limiting groove 15 of the powder spreading plate 10 through the limiting block 16, driving the powder spreading plate 10 to vibrate back and forth. At the same time, the inclined block 14 on the powder spreading plate 10 contacts the guide post 13 in the fixed box 3. When the powder spreading plate 10 moves back and forth, the inclined block 14 slides along the inclined surface through the guide post 13, forcing the powder spreading plate 10 to move left and right. The spring 18 on the limiting rod 17 generates an elastic restoring force when the powder spreading plate 10 moves left and right. It works in conjunction with the sliding limit of the support plate 9 in the sliding groove 8 to realize the synchronous vibration of the powder spreading plate 10 in the back and forth and left and right directions, ensuring that the powder is evenly dispersed.
[0026] like Figure 5 As shown, this utility model provides a technical solution: Preferably, a powder feeding pipe 20 is fixedly connected to the outer wall of the storage tank 6, a motor 24 is fixedly connected to the upper side of the storage tank 6, a limiting disk 21 is fixedly connected to the output shaft of the motor 24, a gear ring 22 is fixedly connected to the inner surface of the storage tank 6, the outer wall of the limiting disk 21 is rotatably connected to the storage tank 6, a gear 23 is meshed with the inner surface of the gear ring 22, a rotating shaft 25 is fixedly connected to the lower side of the gear 23, a plurality of stirring rods 26 are fixedly connected to the lower end of the rotating shaft 25, a filter plate 19 is fixedly connected to the inner surface of the storage tank 6, and the outer wall of the rotating shaft 25... The powder raw material is rotatably connected to the limiting plate 21. It is added to the storage tank 6 through the powder adding pipe 20. First, it is screened by the filter plate 19 to remove large particles or lumps. The fine powder that meets the particle size requirements falls to the lower part of the storage tank 6. The motor 24 drives the limiting plate 21 to rotate. The limiting plate 21 drives the gear 23 to revolve around the gear ring 22. At the same time, the gear 23 rotates on its own due to meshing with the gear ring 22. Then, it drives the stirring rod 26 to rotate and stir through the rotating shaft 25, which improves the screening efficiency of the device and ensures that the powder output from the discharge pipe 7 has a uniform particle size, avoiding the problem of particle accumulation or insufficient powder during powdering.
[0027] The working principle of the automatic powder-sprinkling device used in pastry production will be explained in detail below.
[0028] like Figure 1-5 As shown, when the electric telescopic rod 11 extends or retracts, it drives the movable block 12 to move back and forth. The movable block 12 is slidably connected to the limiting groove 15 of the powder-spreading plate 10 through the limiting block 16, driving the powder-spreading plate 10 to vibrate back and forth. At the same time, the inclined block 14 on the powder-spreading plate 10 contacts the guide post 13 in the fixed box 3. When the powder-spreading plate 10 moves back and forth, the inclined block 14 slides along the inclined surface through the guide post 13, forcing the powder-spreading plate 10 to move left and right. The spring 18 on the limiting rod 17 generates an elastic restoring force when the powder-spreading plate 10 moves left and right, which, together with the sliding limit of the support plate 9 in the sliding groove 8, realizes the forward and backward and left and right directions of the powder-spreading plate 10. The synchronous vibration ensures uniform powder dispersion. The powder raw material is added to the storage tank 6 through the powder adding pipe 20. First, it is screened by the filter plate 19 to remove large particles or lumps. Fine powder that meets the particle size requirements falls to the lower part of the storage tank 6. The motor 24 drives the limiting plate 21 to rotate. The limiting plate 21 drives the gear 23 to revolve around the gear ring 22. At the same time, the gear 23 rotates on its own due to meshing with the gear ring 22. Then, it drives the stirring rod 26 to rotate and stir through the rotating shaft 25, which improves the screening efficiency of the device and ensures that the powder output from the discharge pipe 7 has a uniform particle size, avoiding the problem of particle accumulation or insufficient powder during powdering.
[0029] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
