Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of powdering devices, in particular to an automatic powdering device capable of adjusting the granularity of powder. BACKGROUND

[0002] In the process of making cakes, it is necessary to sprinkle powder on the finished cakes, which requires the use of a powdering machine. The powdering machine is a special device for uniformly sprinkling powder (such as flour, sugar powder, cocoa powder, etc.) on the surface of cakes. This device is commonly used in the baking industry and can help producers achieve precise powdering of cakes during the baking process, improving production efficiency and product quality. During the powdering process of cakes, the powdering machine has a wide powdering range. Therefore, after the powder is poured into the powdering machine, it will generally accumulate at the center or one side of the powdering machine. In the case of needing to sprinkle powder on the center of the product on the production line, only the powder at the center of the powdering machine needs to be poured downward, and the powder on both sides does not need to be poured. In the case of needing to uniformly sprinkle powder on the entire surface of the product, the powder at the bottom of the powdering machine needs to be poured downward. In the prior art, most powdering machines have the problem that the powder accumulates at the center or one side during use, which causes the powder to not flow uniformly from the bottom of the powdering machine during the powdering process, resulting in uneven powdering, affecting the quality and appearance of the product, and the range of powdering cannot be adjusted. Therefore, it is not possible to choose the appropriate powdering method according to the specific production requirements and product characteristics, resulting in low production efficiency, high powder waste, and inability to ensure the quality and appearance of the product.

[0031] Secondly, the "one embodiment" or "embodiment" referred to herein means a specific feature, structure or characteristic that can be included in at least one implementation of the present application. "In one embodiment" appearing in different places in the specification does not mean the same embodiment, nor does it mean an embodiment that is separate or alternative to other embodiments.

[0032] Embodiment 1

[0033] Reference Figure 1 - Figure 10 For the first embodiment of the present application, the embodiment provides an automatic powdering device capable of adjusting the particle size of powder, which comprises a main assembly 100 and an auxiliary assembly 200, and the cooperation of the two can improve the quality and appearance of the product.

[0034] The main assembly 100 comprises a shell 101, a rotating roller 102, an insert plate 103 and a screen 104. The rotating roller 102 is arranged in the shell 101, the insert plate 103 is inserted into the shell 101, and the screen 104 is located in the insert plate 103.

[0035] The rotating roller 102 is provided with a brush on the outside, and the rotating roller 102 is connected with an external motor. The bottom of the shell 101 and the insert plate 103 are both provided with a powder falling groove. When the rotating roller 102 rotates, the powder in the shell 101 can be leaked out downward through the screen 104. The screen 104 is movably connected in the insert plate 103. By replacing the screen 104, the particle size of the leaked powder can be adjusted, so that powder of different thickness can be powdered.

[0036] A guide plate is rotatably connected in the shell 101 through a rotating shaft. The guide plate is located above the rotating roller 102 and is inclined. The falling powder will flow to one side of the rotating roller 102 through the guide plate, and will not accumulate on the top of the rotating roller 102.

[0037] The auxiliary assembly 200 is arranged in the shell 101 and comprises a shunt 201, a transmission member 202, a pushing member 203, a connecting member 204, a locking member 205 and a pressing member 206. The shunt 201 is arranged in the shell 101. The transmission member 202 is located in the shunt 201. The pushing member 203 is arranged in the shunt 201. The connecting member 204 is located on the outside of the transmission member 202. The locking member 205 is arranged on the outside of the shunt 201. The pressing member 206 is located on one side of the shell 101.

[0038] By the setting of the shunt 201, the powder poured into the inside of the shell 101 can be transported to both sides, and then the powder can be uniformly discharged from the bottom of the shell 101, and then the powder can be uniformly scattered, and the quality and appearance of the product can be improved. By the setting of the transmission member 202, the transmission member 202 is used to drive the shunt 201 to rotate, so that the shunt 201 does not need to be additionally driven, and then the energy consumption can be reduced. By the setting of the pushing member 203, when the shunt 201 rotates, the pushing member 203 can be driven to move, so that the pushing member 203 opens the bottom of the shunt 201, and then the powder can fall downward.

[0039] By the setting of the connecting member 204, the transmission member 202 is connected with the shunt 201, so that the transmission member 202 can drive the shunt 201 to rotate. When the shunt 201 does not need to rotate, the locking member 205 is used to lock the shunt 201, so that the shunt 201 cannot rotate when it is vibrated. By the setting of the pressing member 206, the connecting member 204 is driven to move, so that the connecting member 204 can connect the transmission member 202 with the shunt 201.

[0040] Embodiment 2

[0041] Reference Figure 1 - Figure 10 This is the second embodiment of the application, which is based on the previous embodiment.

[0042] Specifically, the shunt 201 includes a material falling box 201a, a fixed sleeve 201b, a rotating sleeve 201e, an auger 201c and a material blocking plate 201d.

When the powder is poured into the inside of the material falling box 201a and the auger 201c rotates, the powder can be transported to both sides, and then the powder can be uniformly discharged from the bottom of the shell 101. The conveying efficiency of the auger 201c is greater than the discharging speed of the discharging groove at the bottom of the fixed sleeve 201b, and then the auger 201c can convey the powder to the end of the fixed sleeve 201b.

[0044] The fixed sleeve 201b is fixed with positioning blocks on both sides, the material blocking plate 201d is fixed with a positioning shaft on one side, the positioning shaft is movably connected with the positioning blocks, a torsional spring is fixed outside the positioning shaft, one end of the torsional spring is fixed with the positioning blocks, when the auger 201c rotates, the material blocking plate 201d will open downward, so that the powder can be discharged downward, at this time, the bottom of the shell 101 can be completely discharged downward, thereby the powdering range can be improved, when the auger 201c stops rotating, the torsional spring will exert a rotating force on the positioning shaft, and the positioning shaft drives the material blocking plate 201d to rotate upward, so that the material blocking plate 201d can block the powder in the fixed sleeve 201b, thereby the bottom of the shell 101 can be stopped from discharging on both sides, and only the center can be discharged downward, so that the powdering mode can be selected according to the specific production requirements and product characteristics, thereby the production efficiency is improved, the powder waste is reduced, and the quality and appearance of the product are ensured.

[0064] The connecting rod 206b drives the extrusion rod 206a to move, so that the extrusion rod 206a extrudes the inclined surface of the rotating block 204a. In this way, the rotating block 204a can be pushed to move, and then the tooth block 204b can be engaged with the tooth groove 201e-1.

Through the cooperation of the two limiting holes 206c-1 and the limiting column 206e, the connecting rod 206b can be locked at different positions. The fourth spring 206g is used to exert a downward pulling force on the support plate 206f, and drives the limiting column 206e to move downward through the support plate 206f. In this way, the limiting column 206e can be more tightly engaged with the limiting column 206e.

[0067] In use, when only the bottom center of the shell 101 needs to be discharged, the powder is poured into the discharge box 201a, and the powder is discharged downward through the discharge slot at the bottom of the discharge box 201a. The falling powder flows to one side of the rotating roller 102 through the guide plate. At this time, the rotating roller 102 can discharge the powder in the shell 101 downward through the screen 104.

[0068] When the bottom of the shell 101 needs to be completely discharged, the limiting column 206e is pulled out upward, so that the limiting column 206e is separated from the current limiting hole 206c-1, thereby releasing the limitation of the connecting rod 206b, and the connecting rod 206b is pushed to drive the extrusion rod 206a to move, so that the extrusion rod 206a extrudes the inclined surface of the rotating block 204a, thereby the rotating block 204a is pushed to move, when the rotating block 204a moves to the side of the rotating sleeve 201e, the tooth block 204b is engaged with the gear groove 201e-1, through the cooperation of the two, the rotating block 204a drives the rotating sleeve 201e to rotate, so that the rotating sleeve 201e drives the auger 201c to rotate.

At the same time, when the rotating sleeve 201e rotates, the connecting sleeve 203b is driven to rotate, at this time, under the action of centrifugal force, the induction ball 203e moves to the end of the connecting sleeve 203b, and drives the connecting column 203d and the extrusion plate 203c to move, so that the extrusion plate 203c pushes the push block 203a to move downward, and the push block 203a pushes the blocking plate 201d to move downward, so that the blocking plate 201d is opened downward, and the powder in the fixed sleeve 201b is discharged downward through the discharging groove.
