Description

Technical Field

[0001] This invention relates to the field of food processing conveyor technology, and in particular to a feeding device for automatic processing of fermented foods. Background Technology

[0002] In actual fermented food processing, such as bread, after the initial mixing and kneading, the dough needs to be transferred to a fermentation tank for further fermentation. This transfer is typically done using a belt conveyor for labor-saving transport, which offers advantages such as high efficiency. However, current automated fermented food processing feeding devices often place the dough directly on the conveyor belt, making it inconvenient to handle. Softer dough can easily get stuck at the conveyor belt edges, hindering transfer via trays. Furthermore, during continuous dough transport, if workers at the retrieval end are not quick enough to pick up the dough, it can easily fall off the conveyor. The dough transport speed also doesn't automatically adapt to the workers' retrieval speed. Summary of the Invention

[0025] In Example 2, based on Example 1, the temporary storage section 5 includes: a temporary storage bracket 501 and a discharge port 5011. The discharge port 5011 is provided at the bottom of the temporary storage bracket 501. The temporary storage bracket 501 is fixedly installed on the feeding roller frame 101 by bolts. The discharge port 5011 is used for conveying and discharging the receiving tray 301. The temporary storage section 5 also includes: guide angle steels 502. Four guide angle steels 502 are fixedly installed on the temporary storage bracket 501, and a row of receiving parts 3 are slidably inserted into the inner side of the four guide angle steels 502. The positioning part 6 includes: a rotating shaft 601, a swing rod 602, and a positioning block 603. The rotating shaft 601 is fixedly installed on the temporary storage bracket 501.

Positioning block 603 is fixedly installed on the upper part 2; positioning block 603 is inserted into the slot on the same side of the receiving plate 301; the temporary storage part 5 allows the staff to temporarily store the receiving plate 301 with dough placed on it in batches at the feeding end of the feeding installation part 1, which can reduce the feeding pressure and make the feeding more flexible. The staff does not need to hold the receiving plate 301 and wait for the placement slot 2011 on the conveyor belt 201 to run into place, which can realize automatic material conveying. In the actual dough conveying operation, this structure, together with the positioning part 6, can flexibly control the normal conveying and pause of the receiving plate 301, further increasing the flexibility of material conveying, and is more suitable for adjusting the production and transportation batches on the production line. The structure is simple to operate.

[0026] The working principle of this embodiment is as follows: First, the support leg 102 is installed on the ground through the through hole and bolted. The worker at the feeding end places the dough into the receiving tray 301, then holds the handle on the crossbeam 304 and inserts the receiving tray 301 between the four guide angle steels 502. The receiving trays 301 can be stacked in batches inside the four guide angle steels 502 for batch feeding. Then, the drive motor 105 is started to drive the conveyor wheel 104, which in turn drives the conveyor belt 201. At this time, the placement groove 2011 on the conveyor belt 201 passes through the receiving tray 301. When the receiving tray 301 falls naturally into the placement trough 2011 under the action of gravity, it is then discharged from the discharge port 5011 at the bottom of the temporary storage bracket 501 as the conveyor belt 201 continues to transport the dough. As the conveyor belt 201 continues to run, a row of receiving trays 301 inside the four guide angle steels 502 can fall automatically into the placement trough 2011 in sequence, realizing automatic feeding. When the receiving tray 301 falls into the placement trough 2011, the inclined structure of the positioning shaft 305 is used to position the dough. The material can be slid into the positioning cylinder 202 through the outer edge for positioning. If it is necessary to pause the falling material discharge of the receiving plate 301 in the four guide angle steels 502, the swing rod 602 can be rotated directly to drive the positioning block 603 to be inserted into the slot on the receiving plate 301 for positioning. As the conveyor belt 201 continues to transport the receiving plate 301, when the receiving plate 301 moves to the material picking position, the worker can manually slide the two crossbars 304 inward to compress the positioning spring 303. At this time, the positioning shaft 305 can be pulled out from the positioning cylinder 202 to release the limit. The worker can then directly lift out the receiving plate 301, and the dough in the receiving plate 301 will undergo subsequent fermentation. If the staff does not pick up the material in time, the receiving tray 301 will continue to be conveyed. When the receiving tray 301 moves close to the end of the feeding roller frame 101, the receiving tray 301 will first squeeze and push the swing plate 402, causing the swing plate 402 to rotate. At this time, the torsion spring 403 will undergo elastic deformation and store force, and then the squeezing groove 4021 can rotate. The inclined surface inside the squeezing groove 4021 will squeeze the pressing end of the micro switch 406. At this time, the micro switch 406 can quickly control the drive motor 105 to stop running. After the staff removes the receiving tray 301, the receiving tray 301 will no longer squeeze the swing plate 402. At this time, the swing plate 402 will automatically reset under the elastic squeezing of the torsion spring 403. The micro switch 406 will no longer be squeezed, and the drive motor 105 can resume normal operation, realizing automatic adaptation to the staff's material picking speed.
