Problems solved by technology
[0003] 1. Since multiple bags cannot be packaged at the same time, whether it is a single station or multiple stations, there is a problem of low production efficiency
[0004] 2. The filling and vacuuming of materials are all completed in a plastic mold. If the packaging shape of the article is to be changed, the plastic mold needs to be replaced, which obviously increases the cost of the equipment and also brings inconvenience to use.
However, for this type of mold, the partial opening of the top-opening and side-opening covers of the vacuum chamber previously brought inconvenience to the specific operation, and also restricted the improvement of production efficiency.

Embodiment Construction
[0025] see figure 1 , figure 2 , in the present embodiment, the vacuum chamber is a structural form in which the left half box 1 and the right half box 2 are closed; wherein, the left half box 1 is fixedly arranged on the frame 3, the right half box 2 is a movable part, and the right half box 2 is a movable part. The relative movement of the half box 2 makes the left half box 1 and the right half box 2 or close up to form a closed cavity, or open to be an opening.
[0026] figure 1 as shown, figure 2 As shown, in order to make the opening process light, smooth, and reduce manpower, an opening and closing mechanism can be arranged on the frame. The opening and closing mechanism is a piston rod 5 driven by a cylinder 4, and the piston rod is set in the direction of moving along the right half box 2. Guide rail 6, right half box 2 are fixedly connected on the piston rod 5. In specific implementation, such as figure 2 As shown, the opening and closing mechanism can be arra...

The invention relates to a semi-closed vacuum cavity of a vacuum package machine, which is characterized in that the vacuum cavity is a left-right shut structural form of a left half box and a right half box, wherein, the left half box is fixedly arranged at a frame while the right half box is a movable part, and the relatively movement of the right half box can lead the left half box and the right half box to close to be a closed cavity or to open. The vacuum cavity can lead the vacuum package form of shaping moulds with the retractable left and right formed by a bottom support plate, a left side plate and a right side plate to be applied better, which is very convenient for use and can increase the production efficiency effectively.
Description
technical field [0001] The invention relates to a vacuum chamber of a vacuum packaging machine, more specifically a vacuum chamber used in a vacuum packaging machine for granular and powdery materials. Background technique [0002] Vacuum shaping and sealing devices are widely used in granular or powdery materials such as yeast, rice, and tea. At present, the existing vacuum shaping and sealing devices mainly have the following problems: [0003] 1. Since multiple bags cannot be packaged at the same time, whether it is a single station or multiple stations, there is a problem of low production efficiency. [0004] 2. The filling and vacuuming of the materials are all completed in one plastic mold. If the packaging shape of the article is to be changed, the plastic mold needs to be replaced, which obviously increases the equipment cost and also brings inconvenience in use. [0005] There is a technical solution in which the bottom supporting plate and the left and right side...
