Description

Technical Field

[0001] This utility model relates to the field of product processing, and in particular to a vacuum packaging device. Background Technology

[0002] Creating a vacuum environment during product packaging can effectively extend shelf life and improve product quality. Existing vacuum packaging devices mostly use vacuum pumps to extract air from the packaging bag to create a vacuum before sealing. This method suffers from problems such as generating significant noise during vacuuming and requiring a large area for the pump. These issues not only affect the external environment due to noise but also make the vacuum packaging machine inconvenient to move, thus impacting efficiency. Therefore, it is necessary to improve and optimize vacuum packaging devices. Utility Model Content

[0003] The purpose of this invention is to provide a vacuum packaging device to solve the problems of excessive noise affecting the outside world and the large space occupied by the device making it difficult to move.

[0004] This utility model mainly provides a vacuum packaging device, which includes a shell with a accommodating space. A first claw and a second claw are arranged in the accommodating space. The first claw and the second claw are symmetrical about the center line of the shell. The first claw and the second claw are respectively provided with a rotating shaft, so as to control the first claw and the second claw to rotate around their respective center lines to discharge the air absorbed by the air inlet from the air outlet.

[0005] Further technology of this utility model:

[0006] Preferably, the housing includes a bottom, a surrounding plate, and a top. An air inlet is provided on a first side of the surrounding plate, and a plurality of air outlets are provided on a second side of the surrounding plate opposite to the first side. The first claw and the second claw are respectively spaced apart from the surrounding plate.

[0007] Preferably, the top of the shell is provided with a cover plate, and the cover plate is provided with two through holes.

[0008] Preferably, the first claw body includes a first rotating shaft, and the second claw body includes a second rotating shaft.

The power unit is provided with a power switch to provide power to the drive device.

[0009] Preferably, the first claw body and the second claw body are S-shaped. The first rotating shaft and the second rotating shaft are driven by the driving device respectively, so that the first claw body and the second claw body rotate around different directions. During the rotation, a cavity is generated between the first claw body and the second claw body, thereby absorbing the air on the air inlet side and then discharging it from the exhaust port.

[0010] Preferably, the first claw body and the second claw body are respectively provided with a first connecting port and a second connecting port at their centers. A first annular fixing member and a second annular fixing member are respectively provided in the first connecting port and the second connecting port. A first pin and a second pin are respectively provided on the inner side of the first annular fixing member and the second annular fixing member. A first rotating shaft is inserted into the first connecting port and a second rotating shaft is inserted into the second connecting port. One end of the first rotating shaft is provided with a first connecting end and one end of the second rotating shaft is provided with a second connecting end. A first groove and a second groove are respectively provided on the outer side of the first connecting end and the second connecting end. By inserting the first pin into the first groove and the second pin into the second groove, the first rotating shaft is fixed in the first claw body and the second rotating shaft is fixed in the second claw body.

[0011] Preferably, screws are provided in the first connection port and the second connection port respectively, and the bottom of the screws are connected to the first connection end and the second connection end respectively through the first annular fixing member and the second annular fixing member.

[0013] Preferably, the top of the hot melter is provided with a slide rail, and a sliding switch is provided on the slide rail to control the opening and closing of the baffle inside the hot melt port.

[0014] The beneficial effects of this utility model are:

[0015] This invention uses two S-shaped claws to form a claw vacuum pump for suction, creating a vacuum environment inside the packaging bag. Compared to using an air pump to create a vacuum environment, the claw vacuum pump method is quieter and reduces the impact on the outside world. Compared to large-scale air-pumping vacuum equipment, the air-pumping vacuum equipment using the claw vacuum pump is more convenient and faster to move, and the product has higher efficiency.
