Description

Technical Field

[0001] The invention relates to the field of conveying devices, in particular to a shortbread discharging device with high protection. Background Art

[0002] Shortbread is named after the special fat-fried crispy cake. It is characterized by golden color, clear layers, crisp but not broken, oily but not greasy, fragrant and delicious. Among them, Jinhua shortbread is the most famous. The processing of shortbread in food industrialization requires the assistance of discharging device.

[0003] A common discharging and conveying device is to transport through a conveyor. This discharging method has a major defect for shortbread, because there is puff pastry on the surface of the shortbread, and it is fragile. Conventional conveyors will place more shortbread on the conveyor belt and transport them at the same time. In this method, the shortbread will collide with the side wall or other positions of the conveyor during transportation, or the adjacent puff pastry will be squeezed and collided, causing the puff pastry to fall on the conveying path. For a long discharging line, it is more difficult to clean up the debris, which will also affect the quality of the shortbread to a certain extent. In addition, when delivering the shortbread, it cannot be delivered in an arranged manner. For subsequent packaging, manual sorting and stacking are required, which takes a lot of time and affects the discharging efficiency of the shortbread. Summary of the invention

The four groups of storage frames 54 receiving the shortbreads move away from the upper conveying platform 3 synchronously. After reaching the stacking position, the second electric push rod 42 drives the top plate 43 to descend. At this time, the storage frame 54 and the telescopic plate 51 synchronously descend and approach the placement plate 12. Since the slot 32 has a space for the telescopic plate 51 to move up and down, the lifting and lowering movement of the telescopic plate 51 will not interfere with each other. When the storage frame 54 is close to the placement plate 12, the storage frame 54 is moved away from the upper conveying platform 3.

The stacking position starts from the farthest distance between the placing plate 12 and the upper conveying platform 3, and the upper conveying platform 3 conveys the shortbread in rows. The storage frame 54 After receiving a biscuit, it is sent out. When the storage frame 54 and the telescopic plate 51 descend with the top plate 43, the insertion rods 57 on both sides of the telescopic plate 51 are inserted into the baffle 56 and compress the spring 58. The position of the baffle 56 remains unchanged. At this time, the outlet end of the storage frame 54 is close to the placement plate 12, and the biscuit is sent out by tilting. The sending out is blocked by the baffle 56 and stays at the designated position, thereby completing the stacking of the biscuits in sequence. After the placement plate 12 is fully loaded with biscuits, the lower conveyor table 1 slowly sends it out, and a new placement plate 12 is sent in for the next group of stacking.
