Description

Technical Field

[0001] The utility model relates to the technical field of packaging equipment, in particular to an automatic packaging machine with a positioning function. Background Art

[0002] my country is a country with a large population and the demand for food is increasing, especially in the steamed bun processing industry. With the development of science and technology, machines are gradually replacing manual labor to realize automated work. Currently, most steamed buns are packaged by packaging machines.

[0003] According to the description of a steamed bun processing and packaging machine disclosed in the patent website (authorization announcement number: CN 219277966U), "The utility model provides a steamed bun processing and packaging machine, which belongs to the technical field of packaging machines. The steamed bun processing and packaging machine includes a conveyor belt, a conveyor roller, a packaging mechanism and a cleaning mechanism. The utility model sets a packaging mechanism to place the steamed buns on the top of the conveyor belt. The length of the steamed buns can be measured by the second displacement sensor, so as to automatically determine the number of steamed buns. After the specified number of steamed buns is reached, the conveyor belt is briefly stopped. After the steamed buns enter the conveyor roller, the conveyor belt is started and continues to convey; the steamed buns enter the packaging bag through the positioning frame. The length of the moving packaging bag can be measured by the first displacement sensor. After reaching the set length, the two heat-sealing knives move close to each other to seal the packaging bag, thereby realizing automatic recognition of the number of steamed buns and automatic sealing. There is no need to manually count the number of steamed buns in each bag before packaging, which reduces the workload of personnel and improves the efficiency of steamed bun packaging."

[0004] In view of the above description, the applicant believes that there are the following problems:

[0005] During the use of the utility model, the second displacement sensor can measure the length of the steamed buns, thereby automatically determining the number of steamed buns. When the specified number of steamed buns is reached, the conveyor belt stops briefly, and after the steamed buns enter the conveying rollers, the conveyor belt starts to continue conveying. However, in actual use, the sizes of the steamed buns are different, and they may not be placed neatly when being transported, so that when the lengths are the same, the numbers of steamed buns are also different, resulting in different numbers of steamed buns in each bag and a lower pass rate. Therefore, it is necessary to improve an automatic packaging machine with a positioning function to solve the above problems. Utility Model Content
