Description

Technical Field

[0001] The utility model relates to the technical field of packaging equipment, in particular to a rolling vacuum packaging machine. Background Art

[0002] The structure of the rolling vacuum packaging machine is divided into a vacuum packaging part and a transportation part. The transportation part is composed of a conveyor belt. Heat sealing strips and stop strips are set on the surface of the conveyor belt to limit the packaging bags and ensure the stability of the packaging bags during vacuuming and hot pressing sealing.

[0003] At present, when a packaging workshop needs to pack bags of different sizes, it is necessary to adjust the position of the stays. However, the existing stays are inconvenient to adjust because the two ends of the stays are usually fixed independently by bolts. When adjusting the position, it is necessary to first loosen the bolts at both ends separately, and then tighten them separately when they are moved to the appropriate position. The adjustment is time-consuming and labor-intensive, and the efficiency is low.

[0004] Therefore, we propose a rolling vacuum packaging machine to solve the above problems. Utility Model Content

[0005] The purpose of the present utility model is to provide a rolling vacuum packaging machine to solve the problems raised in the above background technology.

[0008] In a further embodiment, both ends of the leather strip are fixed to the conveyor belt, and the length direction of the leather strip is parallel to the conveying direction of the conveyor belt.

[0009] In a further embodiment, a lifting motor is installed inside the side of the frame, an eccentric wheel is installed at the output end of the lifting motor through a reducer, and the upper edge of the eccentric wheel is tightly fitted with the bottom end of the lifting platform.

[0010] In a further embodiment, annular ridges are provided at both ends of the eccentric wheel, and the two annular ridges are distributed on the front and rear sides of the lifting platform.

[0011] In a further embodiment, two sets of guide wheels are symmetrically provided on the left and right sides of one end of the lifting platform extending into the side of the frame. The guide wheels are rotatably connected to the frame, and the edges of the guide wheels are in contact with the outer wall of the lifting platform.

[0012] In a further embodiment, a panel is movably mounted on the side of the frame, and a handle is provided on the surface of the panel.

[0013] In a further embodiment, an inclined guide plate is installed on the output side of the frame.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] When the utility model is set to pull the connecting rod, it can simultaneously drive the two insertion rods to draw out the positioning holes of the leather strip and compress the spring to shorten it. At this time, the operating strip can be moved to adjust the distance between it and the heat sealing strip to adapt to packaging bags of different specifications. When the movable sleeve moves to the positioning hole at a suitable position along the length direction of the leather strip, the connecting rod is released, and the insertion rod can be inserted into the positioning hole under the elastic force of the spring to be locked in position, making the adjustment of the entire limiting mechanism more convenient and quick, not only reducing the burden of manual operation, but also effectively shortening the downtime adjustment time occupied by the entire packaging machine.
