The term "and / or" used herein includes any and all combinations of one or more of the associated listed items.

[0033] Reference Figures 1-3 , Figure 1 The direction of the arrow is the conveying direction of the baking tray conveying mechanism, and the present application discloses an automatic spreading device, which comprises a base 1, a baking tray conveying mechanism 5, a hopper 2, a spreading mechanism 3 and a baking tray sensor 4. Among them, the baking tray conveying mechanism 5 is arranged on the base 1 for conveying the baking tray. The spreading mechanism 3 comprises a first driving mechanism 31 arranged on the base 1 and a discharging structure 32, the discharging structure 32 is connected with the first driving mechanism 31, the discharging structure 32 is located above the hopper 2, the first driving mechanism 31 is used for driving the discharging structure 32 to move back and forth at a uniform speed along the conveying direction of the baking tray, referring to Figures 4-5and Figure 7 The discharging structure 32 comprises a discharging bin 321, a discharging roller 322 and a second driving mechanism 323. The bottom of the discharging bin 321 is provided with a discharging opening 3211 in the shape of a long strip. The surface of the discharging roller 322 is provided with a plurality of discharging grooves, and the intervals of the discharging grooves in the axial direction of the discharging roller 322 are equal. The discharging roller 322 is located below the discharging opening 3211 and abuts against the discharging bin 321. The second driving mechanism 323 is used to drive the discharging roller 322 to rotate at a constant speed around its own axis. Of course, the rotating speed of the constant speed can be set according to needs. The baking tray sensor 4 is arranged on the base 1 and is used to detect the position of the baking tray. The baking tray conveying mechanism 5 is adapted to control the baking tray to be positioned directly below the hopper 2 according to the position information of the baking tray detected by the baking tray sensor 4. At this time, the lower ends of the respective funnel portions 21 of the hopper 2 are aligned with the mold cavities on the baking tray. It should be noted that the baking tray has a plurality of mold cavities, and each mold cavity is arranged to place the baked food to be sprinkled.

[0034] In use, the required material, which can be granular auxiliary material such as sesame or walnut, is first poured into the discharging bin 321. At this time, due to the blocking effect of the discharging roller 322, the material will not directly leak out of the discharging opening 3211. Only when the discharging roller 322 rotates, the material will fall along the discharging grooves on the surface of the discharging roller 322. Then the baking tray containing the baked food is placed on the baking tray conveying mechanism 5 for conveying. When the baking tray sensor 4 detects that the baking tray moves to the position directly below the hopper 2, the baking tray conveying mechanism 5 stops conveying. At this time, the lower ends of the respective funnel portions 21 of the hopper 2 are aligned with the respective mold cavities on the baking tray. At this time, the first driving mechanism 31 is started to drive the discharging structure 32 to reciprocate along the conveying direction of the baking tray. The second driving mechanism 323 needs to be started when the discharging structure 32 moves. At this time, the material will fall into the hopper 2 from the discharging grooves on the surface of the discharging roller 322 and finally fall onto the baked food in the baking tray through the respective funnel portions 21 of the hopper 2, completing the sprinkling. In the above process, the discharging structure 32 reciprocates once, which can correspond to sprinkling the baked food on two baking trays. Specifically, when the discharging structure 32 moves along the conveying direction of the baking tray, it sprinkles the baked food on one baking tray. After the sprinkling is completed, the baking tray is continuously conveyed by the baking tray conveying mechanism 5, and at the same time, the other baking tray also moves to the position directly below the hopper 2. At this time, the discharging structure 32 moves against the conveying direction of the baking tray, completing the sprinkling of the baked food on the other baking tray. This cycle can realize automatic sprinkling.

[0035] In the above process, since the discharging structure 32 is adapted to move at a constant speed under the drive of the first driving mechanism 31, the discharging roller 322 is adapted to rotate at a constant speed under the drive of the second driving mechanism 323, and the intervals of the plurality of discharging grooves in the axial direction of the discharging roller 322 are equal, the material will be in a relatively uniform state when falling from the discharging grooves to the hopper 2, so that the material will also be in a relatively uniform state when falling from the hopper 2 to the baking food on the baking tray. In addition, by detecting the position of the baking tray through the baking tray sensor 4, it can be ensured that the baking tray is accurately positioned directly below the hopper 2, and at this time the funnel part 21 is aligned with the mold cavity on the baking tray, so that the material scattering range is accurate, thereby improving the qualified rate of the product and reducing the waste of the material.

[0036] As a preferred embodiment, with reference to Figures 1-2 and Figure 6 the connection between the upper ends of the two adjacent funnel parts 21 forms a ridge. That is, the connection of the upper ends of each funnel part 21 does not form a connection plane, so that the material will not accumulate on the connection plane, but directly fall into the funnel part 21 from the ridge, reducing the waste of the material. In this embodiment, the upper end of the funnel part 21 is square, and the lower end is circular.

[0037] Preferably, with reference to Figure 2 the baking tray conveying mechanism 5 comprises a first motor 51, a driving shaft 52 connected with the first motor 51, a driving sprocket 53 arranged on the driving shaft 52, a first driven shaft 54 arranged in the conveying direction of the baking tray and spaced from the driving shaft 52, a driven sprocket 55 arranged on the first driven shaft 54, and a conveying chain plate arranged between the driving sprocket 53 and the driven sprocket 55, the conveying chain plate being located below the baking tray. Specifically, the conveying chain plate has two conveying chain plates, and the baking tray is directly placed on the two conveying chain plates for conveying. The conveying chain plate is used for conveying, which can withstand the high temperature on the baking tray and ensure the reliability of the baking tray conveying.

[0038] Preferably, the first motor 51 is a servo motor. The use of a servo motor can more accurately position the baking tray directly below the hopper 2.

[0039] Preferably, with reference to Figures 2-3The first driving mechanism 31 comprises a guide rail 311 arranged on the base 1, a sliding block 312 in sliding cooperation with the guide rail 311, a second motor 313 arranged on the base 1, a driving shaft 314 connected with the second motor 313, a driving synchronous wheel 317 arranged on the driving shaft 314, a second driven shaft 315 arranged at intervals with the driving shaft 314 along the conveying direction of the baking tray, a driven synchronous wheel 316 arranged on the second driven shaft 315, and a synchronous belt 318 arranged between the driving synchronous wheel 317 and the driven synchronous wheel 316, the movement direction of the synchronous belt 318 is parallel to the direction of the guide rail 311, the blanking structure 32 is supported on the guide rail 311 through the sliding block 312, and the blanking structure 32 is connected with the synchronous belt 318 through a connecting plate 319. Specifically, the number of the guide rails 311 is two, the number of the sliding blocks 312 is also two, and the bottom of the blanking structure 32 is connected to the two sliding blocks 312. In the above arrangement, the forward and reverse rotation of the second motor 313 can drive the synchronous belt 318 to reciprocate, then the connecting plate 319 is connected with the blanking structure 32, and finally the blanking structure 32 is driven to reciprocate along the guide rail 311.

[0040] Preferably, the second motor 313 is a servo motor. Here, the servo motor is adopted, so that the blanking structure 32 can quickly start and end the movement, thereby reducing the uneven scattering of materials caused by the long acceleration and deceleration process when starting and stopping the movement.

[0041] Preferably, when the first driving mechanism 31 drives the blanking structure 32 to reciprocate at a uniform speed along the conveying direction of the baking tray, the plane swept by the blanking roller 322 just covers the upper end surface of the hopper 2. Through such an arrangement, the accuracy of the scattering range can be further ensured, and the possibility of the materials falling outside the baking tray can be reduced.

[0042] Preferably, with reference to Figures 2-5 , Figure 4The arrow direction in the figure is the running direction of the conveying belt 325. The discharging structure 32 further comprises a third motor 324 and a conveying belt 325 arranged below the discharging roller 322. The third motor 324 is used to drive the conveying belt 325 to run at a uniform speed. Of course, the third motor 324 can control the conveying belt 325 to run at different speeds as needed. When the first driving mechanism 31 drives the discharging structure 32 to reciprocate at a uniform speed along the conveying direction of the baking tray, the discharging end of the conveying belt 325 sweeps a plane that just covers the upper end surface of the hopper 2. In this way, the accuracy of the material spreading range can be further ensured, and the possibility of the material falling outside the baking tray can be reduced. In addition, in this arrangement, the material first falls on the conveying belt 325 and then falls into the hopper 2 from the conveying belt 325. Through the impact of the conveying belt 325, the material can be further spread out, especially for some materials that stick together, which can be more evenly arranged on the conveying belt 325, thereby further improving the uniformity of the material spreading.

[0043] It is worth noting that when the conveying belt 325 is added, in addition to controlling the density of the material spreading through the rotating speed of the discharging roller 322, the running speed of the conveying belt 325 can also control the density of the material spreading. That is, the density of the material spreading can be adjusted by the conveying belt 325 and the discharging roller 322 to more levels to meet more requirements of the material spreading density.

[0044] Preferably, referring to Figures 3-4 , the discharging structure 32 further comprises a material blocking plate 326 arranged in front of the discharging end of the conveying belt 325. By arranging the material blocking plate 326 in front of the discharging end of the conveying belt 325, the material can be prevented from flying out of the hopper 2 area from the discharging end of the conveying belt 325, further ensuring the accuracy of the material spreading range.

[0045] Preferably, referring to Figure 1 and Figures 3-4 , the discharging structure 32 further comprises two oppositely arranged blocking plates 327 and an adjusting hand wheel 328 for adjusting the tension of the conveying belt 325. The two oppositely arranged blocking plates 327 are arranged above the conveying belt 325 along the conveying direction of the conveying belt 325. By arranging the two oppositely arranged blocking plates 327, the possibility of the material bouncing after falling on the conveying belt 325 can be reduced, and the waste of the material can be reduced. At the same time, the blocking plates 327 also limit the material falling area, further ensuring the accuracy of the material spreading range. The adjusting hand wheel 328 can adjust the tension of the conveying belt 325, thereby ensuring the reliability of the conveying belt 325 running, and also preventing the conveying belt 325 from deviating when adjusting.

[0046] The above merely illustrates the embodiments of the present application, and does not limit the patent scope of the present application, and any equivalent structure or equivalent process transformation, or direct or indirect application in other related technical fields, which are made by using the content of the present application specification and drawings, are also included in the patent protection scope of the present application.
