Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. As shown in fig. 2 and 3, the food vacuum packaging machine according to the present invention includes a rotating disc capable of rotating circumferentially and a plurality of vacuum pumping assemblies uniformly distributed along the periphery of the rotating disc, wherein each vacuum pumping assembly includes an upper cover 2 and a lower cover 1, and an openable structure is provided between the upper cover 2 and the lower cover 1, so as to form a cavity for accommodating food packages after being closed.

Generally, a clamping mechanism is also integrated on the lower cover 1 to evacuate the pipe. The vacuumizing assembly further comprises a driving mechanism for driving the upper cover 2 and the lower cover 1 to open and close, and the driving mechanism is generally a connecting rod assembly driven by an air cylinder.

A bag pressing assembly J is arranged inside the upper cover 2 and comprises a pressing plate 21 and a spring 25, wherein the pressing plate 21 is connected to the inner wall of the upper cover 2 facing the lower cover 1 through the spring. In the length of the spring 25, the surface of the pressing plate 21 is required to be in contact with the inner wall of the lower cover 1 or the distance is less than 1cm in a natural state, and the pressing plate 21 compresses the food under the action of the spring 25 in the vacuum-pumping process.

The distance between the upper surface of the bottom of the pressing plate 21 and the inner wall of the upper cover 2 is larger than the distance between the upper surface of the top of the pressing plate 21 and the inner wall of the upper cover 2. The flow of food from the bottom to the top is facilitated during the compression of the food bag.

The pressing plate 21 is a plate with a right trapezoid cross section, is a plastic plate or an aluminum plate, and has a right-angled side surface facing the inner wall of the upper cover 2. Through the shape of the right trapezoid plate, the distance between the upper surface of the bottom of the pressing plate 21 and the inner wall of the upper cover 2 can be effectively ensured to be larger than the distance between the upper surface of the top of the pressing plate 21 and the inner wall of the upper cover 2 under the condition that one specification is selected by the spring 25. The angle of the lower bottom angle of the other waist of the right trapezoid with the cross section of the pressing plate 21 is 60-80 degrees, the inclination angle of the pressing plate is controlled while the technical effects are achieved, on one hand, the thickness and the weight of the pressing plate 21 can be reduced, and on the other hand, the food packaging bag with smaller thickness after filling can be compatible.

In order to avoid damaging the food packaging bag in the compressing process, the upper surface of the pressing plate 21 is provided with a buffer layer 22, and the buffer layer 22 is a rubber or sponge layer.

In order to avoid the pressure plate 21 from shaking in the pressing process, the side surfaces of the periphery of the pressure plate 21 are provided with sliding protrusions 23 which are matched with grooves 24 arranged on the side surfaces of the inner wall of the upper cover 2, namely, the end parts of the sliding protrusions 23 are inserted into the grooves 24 to limit the lateral movement of the pressure plate 21.

In addition, a pressure sensor 26 can be arranged between the spring 25 at the bottom and the inner wall of the upper cover 2, and at this time, the surface of the pressing plate 21 is required to be in contact with the inner wall of the lower cover 1 in a natural state, that is, when the spring 25 is not pressed or is pressed to be small, that is, when the upper cover 2 and the lower cover 1 are not put into a food bag and are closed. The pressure sensor 26 is electrically connected with the equipment controller, and whether the food bag is filled with the product or not can be determined through the change of the numerical value of the pressure sensor 26, so that the empty bag detection can be carried out.
