Description
Technical Field
[0001] This utility model relates to the field of baozi skin processing technology, and in particular to a baozi skin pressing device for xiaolongbao production. Background Technology
[0002] A dumpling skin pressing device is a piece of equipment used to make dumpling skins. It is mainly used to automatically press dough into thin skins that meet the requirements for wrapping dumpling fillings. This device is commonly used in the food processing industry.
[0003] Currently, most methods for pressing steamed bun wrappers involve using conveyor belts. While this allows for continuous pressing, the conveyor belt must be stopped while pressing the wrappers, and the next wrapper can only be pressed after the previous one is finished. This process of pressing and changing wrappers wastes time, especially when pressing a large number of wrappers, thus reducing pressing efficiency.
[0004] Therefore, it is necessary to provide a dough pressing device for xiaolongbao production to solve the above-mentioned technical problems. Utility Model Content
[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a steamed bun skin pressing device for the production of xiaolongbao (soup dumplings).

[0014] The rotating assembly includes two fixed blocks fixedly connected to the bottom of an annular plate. A rotating shaft is rotatably connected between the two fixed blocks on opposite sides. The outer surface of the rotating shaft is fixedly connected to a connecting plate. Two torsion springs are sleeved on the outer surface of the rotating shaft. One end of the torsion spring is fixedly connected to the rotating shaft, and the other end is fixedly connected to one of the fixed blocks. When the connecting plate abuts against the guide support plate, the torsion spring is in a torsional state that generates elastic force.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0031] Reference Figure 1-4 The present invention provides a steamed bun skin pressing device for producing steamed buns, comprising: a processing table 1, a controller 12 on the top of the processing table 1, an annular plate 2 rotatably connected to the top of the processing table 1, a motor 13 fixedly installed at the bottom of the processing table 1, the output end of the motor 13 fixedly connected to the bottom end of the annular plate 2, several pressing grooves 3 penetrating through the top of the annular plate 2, several connecting plates 4 and several rotating components arranged on the annular plate 2, an annular plate 5 fixedly connected to the top of the annular plate 2, a reciprocating screw 6 rotatably connected to the annular plate 2, a screw sleeve 7 threadedly connected to the outer surface of the reciprocating screw 6, a pressing plate 8 fixedly connected to the bottom of the screw sleeve 7, the pressing plate 8 being adapted to the pressing grooves 3, a gear 9 fixedly connected to the top end of the reciprocating screw 6, and two arc-shaped racks 1 on the processing table 1. 0. Several guiding components and feeding components are provided. The top of the processing table 1 is fixedly connected to two support frames 18. The bottom of the two support frames 18 is fixedly connected to the top of two arc-shaped racks 10 respectively. The top of the processing table 1 is provided with a feeding groove 11. Through the arrangement of the processing table 1, annular plate 2, pressing groove 3, connecting plate 4, reciprocating screw 6, gear 9 and arc-shaped rack 10, the reciprocating pressing plate 8, in conjunction with the pressing groove 3 and connecting plate 4, can continuously press the dough block. This is convenient and fast, and solves the problem that the process of pressing and changing the dough to be pressed during the pressing of bun skins wastes a certain amount of time. When a large number of bun skins need to be pressed, it is time-consuming and reduces the efficiency of bun skin pressing. This improves the continuity of the bun skin pressing process.
[0032] A guide support plate 14 is fixedly connected to the top of the processing table 1. The top of the guide support plate 14 is movably abutting against the bottom of the connecting plate 4. The rotating component includes two fixed blocks 15 fixedly connected to the bottom of the annular plate 2. A rotating shaft 16 is rotatably connected between the opposite sides of the two fixed blocks 15. The outer surface of the rotating shaft 16 is fixedly connected to the connecting plate 4. Two torsion springs 17 are sleeved on the outer surface of the rotating shaft 16. With the setting of the rotating component and the guide support plate 14, the bun skin can be automatically unloaded after being pressed, avoiding the problem that workers need to manually unload the bun skin after pressing. This improves the automation level of the device and further improves the pressing efficiency of the bun skin.
[0033] The guide assembly includes a guide rod 19, which is fixedly connected to the bottom of the annular plate 5. The guide rod 19 movably passes through the lead screw sleeve 7. By setting the guide assembly, the lead screw sleeve 7 can be limited, so that it drives the pressing plate 8 to move up and down to perform the pressing work.
[0034] The feeding assembly includes a storage tank 20 and a guide frame 21. Both the storage tank 20 and the guide frame 21 are fixedly connected to the top of the processing table 1. The storage tank 20 is equipped with an extrusion mechanism 22, and the guide frame 21 is equipped with a cutting mechanism 23. Through the setting of the feeding assembly, the dough can be extruded, cut and guided for feeding, which makes it easy to feed the dough block into the pressing groove 3.
[0035] Working principle: During operation, first place the bun skin collection frame below the feed trough 11, then add the kneaded dough into the storage tank 20, and the extrusion mechanism extrudes the dough so that it is squeezed out from the feed outlet of the storage tank 20. Then, the cutting mechanism 23 is activated to cut the extruded dough and let it fall onto the guide frame 21 and be guided into one of the pressing grooves 3.
[0036] When the dough is cut into pieces, the controller 12 starts the motor 13, which drives the first ring plate 2 and the second ring plate 5 to rotate synchronously. After one piece of dough falls into the pressing groove 3, the first ring plate 2 drives it to rotate. During the rotation, other cut pieces of dough can fall into other pressing grooves 3 in sequence. At the same time, the corresponding gear 9 meshes with one of the arc-shaped racks 10. Under the action of the arc-shaped rack 10, the gear 9 drives the reciprocating screw 6 to rotate. Under the guidance of the corresponding guide rod 19, the corresponding screw sleeve 7 moves down along the axis of the reciprocating screw 6, which drives the corresponding pressing plate 8 to move down. It works with the connecting plate 4 to press the dough pieces. After pressing, as the first ring plate 2 rotates, when the corresponding connecting plate 4 no longer abuts against the guide support plate 14, the rotating shaft 16 drives the connecting plate 4 to rotate and tilt under the action of the two torsion springs 17. The pressed bun skin falls into the mobile phone frame through the feeding groove 11.
[0037] After the dough for the buns is cut, the connecting plate 4 can be rotated by the rotation of the ring plate 2 and the guide support plate 14. This will cause the torsion spring 17 to rotate again and generate elastic force. With the continued rotation, the pressing plate 8 can be moved up and reset by the action of another arc-shaped rack 10, which will facilitate the subsequent pressing of other dough pieces.
[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
