Description

Technical Field

[0001] The utility model relates to the field of dumpling making machine equipment, in particular to a dough sheet feeding tensioning and adjusting device of a dumpling making machine. Background Art

[0002] As people's living standards improve, the demand for convenient, fast and delicious food is increasing. Dumplings, as a traditional delicacy, are deeply loved by consumers. At the same time, with the development of the fast food industry, the demand for quick-frozen dumplings is also increasing, which provides a broad space for the dumpling machine market. The development trend of the dumpling machine industry is automation and intelligence. Automatic dumpling machines can reduce labor costs and improve production efficiency. The current dumpling machines feed the dough into the mold for extrusion molding. Since the dough feeding equipment is mostly conveyor belt or roller type, this type of feeding structure cannot adjust the feeding speed according to the real-time tension and drooping degree of the dough, which is easy to cause fast feeding speed, tearing and disconnection of the dough, and slow feeding speed, drooping and adhesion of the dough, which is inconvenient to use. Utility Model Content

[0003] The purpose of the utility model is to provide a dough sheet feeding tensioning and adjusting device for a dumpling making machine in order to solve the above-mentioned problem. Dough sheet feeding tensioning and adjusting device are provided between multiple groups of pressure rollers as feeding support components. A dough sheet spreading bucket is provided on the outside of the dough sheet spreading bucket to detect the distance from the dough sheet being conveyed below. The dough sheet feeding speed of the pressure rollers on both sides is changed accordingly by detecting the tightness of the dough sheet, thereby realizing intelligent dough sheet feeding, avoiding dough sheet tension breakage or excessive looseness and drooping and sticking, and making it more convenient to use. Details are described below.

[0004] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0005] The utility model provides a dough sheet feeding tensioning and adjusting device for a dumpling making machine, comprising a machine body and a dough pressing seat, wherein the dough pressing seat is fixed to the top side of the machine body, a plurality of groups of pressing rollers are evenly arranged in the front of the machine body, and a dough spreading bucket fixed to the front side of the dough pressing seat is arranged between two adjacent groups of pressing rollers;
