Vacuum sealing machine

Abstract

The vacuum sealing machine comprises a machine body, an upper cover, a control device, a vacuum pump body, a heating sealing device, a locking device and a buffering device, a lower vacuum bin is arranged on the machine body, an upper vacuum bin is arranged at the position, corresponding to a lower vacuum cavity, of the upper cover, and the lower vacuum bin communicates with the vacuum pump body; the vacuum pump body and the heating sealing device are electrically connected with the control device, one end of the upper cover is rotatably connected with the machine body, and the other end of the upper cover can cover the lower vacuum bin; a first groove is formed in the bottom of the upper cover, the upper vacuum bin is movably installed in the first groove, and the buffering device is arranged between the upper vacuum bin and the upper cover. The locking device comprises a locking block assembly and a transmission assembly which are matched with each other, the locking block assembly is arranged on the bottom face of the upper cover, an insertion hole is formed in the upper end face of the machine body, and the transmission assembly is arranged in the machine body and located on one side of the insertion hole and electrically connected with the control device. The vacuum sealing machine is good in locking effect, convenient to operate, high in safety, smooth in vacuumizing and high in applicability.

Description

technical field [0001] The invention relates to the field of household electrical appliances, in particular to a vacuum sealing machine. Background technique [0002] Vacuum-packed products use vacuum extraction equipment to remove the air in the vacuum packaging bag, and then cooperate with a hot-melt device to hot-melt the opening of the vacuum packaging bag to achieve the purpose of vacuum sealing in the vacuum packaging bag, so as to keep the food. fresh and hygienic. [0003] The vacuum sealing machine generally includes an upper cover and a lower seat. The rear side of the upper cover is hinged to the lower seat. The upper cover and / or the lower seat are equipped with a vacuum device and a heat sealing assembly, and the upper cover and the lower seat are locked by a locking mechanism. tight. [0004] As shown in the Chinese utility model patent with the application number of 202021305906.1, it discloses a vacuum sealing machine, which includes a lower seat, an upper ...

AI Technical Summary

Problems solved by technology

[0005] As shown in the above-mentioned vacuum sealing machine, the locking mechanism of the vacuum sealing machine currently on the market is generally buckle locking and most of them are manually unlocked and manually locked. The frictional resistance in the process is large, it is easy to damage the locking parts, and the locking force cannot be adjusted, and it is easy to cause the bag to be over-tightened, which will affect the subsequent pumping. Specifically, it may lead to slow pumping, and it is difficult to cool the heating device after working for a long time. Poor sealing effect and other problems
