Description

Technical Field

[0001] The invention relates to a bag throwing machine, in particular to a bag throwing production line. Background Art

[0002] At present, due to the irregular and relatively soft surface of broken bag flavoring packets (flavoring packets including pickled cabbage packets, bamboo shoot packets, kelp packets, radish packets, etc. need to be vacuum packed), the flavoring packets of these instant noodles are generally produced by manually placing and placing the ingredients. This production method requires a large amount of labor, the labor intensity of the workers is also relatively high, and the production cost is high, which is increasingly unable to meet the needs of the rapid development of society. In response to this situation, some automatic feeding bag equipment has also appeared on the market. In theory, these devices can realize the function of feeding flavoring bags, but in actual use, due to the defects of their own design, they cannot meet the needs of efficient automatic production.

[0003] The patent document with application number CN201820022735.8 discloses an automatic feeding machine for broken bag material bags, which realizes the automatic feeding operation of broken bag material bags, greatly improves the feeding efficiency and reduces the labor intensity of workers. However, the equipment is only suitable for the feeding production of broken bag material bags of barreled noodles, and is not suitable for the feeding production of bagged noodles. This is mainly because the feeding machine cannot feed continuously and uninterruptedly, while the feeding and packaging production of bagged noodles is carried out continuously. Therefore, the feeding of broken bag material bags of bagged noodles is still completed by manual feeding. Due to the fast speed of the noodle conveyor line and the large number of noodle cakes conveyed per unit time, the manual feeding method not only has a large labor workload, but also has a particularly high labor intensity. Workers who feed can often only work for half an hour before they have to change personnel to perform feeding operations. These problems have seriously affected the development of the enterprise, and it is urgently necessary to develop a production line that can automatically and continuously feed to meet the needs of the company's continuous development.
