Description

Technical Field

[0001] The present invention relates to the technical field of bread production, and particularly relates to a production line for sandwich bread. Background Art

[0002] Sandwich toast bread and pocket bread are widely loved by people due to their flavors. Mainly, after slicing the bread, sauces are spread between two slices of bread. During the production process of sandwich bread, production quality, efficiency, and equipment costs directly affect the profits of production enterprises. In order to ensure the stable and unified production quality of sandwich bread and improve production efficiency, most sandwich bread manufacturers use production lines to produce sandwich bread. It is found in the actual production process that when slicing the bread in the early stage of the current sandwich bread, the whole bread is cut into multiple slices. Then, sauces are spread between two independent slices of bread. During subsequent transportation and packaging, sauce leakage is likely to occur due to the misalignment of the two slices of bread, seriously affecting the production quality of sandwich bread. At the same time, the last process before packaging for the current sandwich toast bread and sandwich pocket bread is different. The technological process of sandwich toast bread is bread slicing - bread dropping - filling - packaging; the technological process of sandwich pocket bread is slicing - bread dropping - filling - pocket forming - packaging. When producing, a separate production line needs to be set up, resulting in high equipment costs, unable to make full use of the equipment, and wasting equipment resources. Summary of the Invention

At the same time, the pusher component 205 pushes the upright bread slices to make them flat on the surface of the discharging belt conveyor 206, and the opening direction of the bread slices corresponds to the discharging head 308. The discharging belt conveyor 206 conveys the single bread slices, realizing the automatic blanking of single-piece slicing of bread. The bread blanking position is accurate and stable, ensuring the quality of bread production while improving production efficiency and reducing the labor intensity of operators;

[0124] Under the conveyance of the discharging belt conveyor 206, the half-cut bread slices are conveyed to the surface of the sauce spreading belt conveyor 302. As they are conveyed, the opening of the half-cut bread is expanded by the expanding component 304. The sauce spreading and feeding component injects sauce into the inside of the guide pipe 307, and the sauce is spread inside the half-cut bread slices through the discharging head 308, completing the spreading of the sandwich sauce;
