Semi-automatic thermal contraction packaging machine

Abstract

The invention discloses a semi-automatic thermal contraction packaging machine. The semi-automatic thermal contraction packaging machine comprises a rack, and a thermal contraction device, a seal cutting seat, a heat sealing knife rest, a first conveyer belt and a second conveyer belt are arranged on the rack; a heat sealing cutter is arranged on the heat sealing knife rest; the heat sealing knife rest rotates, with a hinge part adopted as the axis, so that the heat sealing cutter is made to be close to or away from the seal cutting seat; and the seal cutting seat can move up and down. According to the semi-automatic thermal contraction packaging machine, through changing the up-and-down position of the seal cutting seat, the height of a closed position of the heat sealing cutter and the seal cutting seat relative to the conveyer belts is changed, when the machine is used to package boxes with different heights, the closed position can be adjusted to the middle parts of the boxes and is horizontally positioned in closed lines at the middle parts of the boxes, the stress is uniform after thermal contraction, and the structure is firm.

Description

technical field [0001] The invention relates to a film sealing machine, more specifically to a semi-automatic heat shrink packaging machine. Background technique [0002] Heat shrinking machine, also known as shrinking machine and shrink packaging machine, is one of the more advanced packaging methods in the market. In addition to its own advantages, it can also reduce the possibility of product being disassembled and stolen; it is suitable for tight packaging and pallet packaging of multiple items. Heat shrinking machines are widely used in the packaging of glass bottles, styrofoam, cartons, toys, electronics, electrical appliances, stationery, books, records, hardware tools, daily necessities, medicines, cosmetics, beverages, fruits, souvenir labels, etc. [0003] The heat shrinking machine generally includes two conveyor belts arranged along the front and rear directions, one is used to convey the wrapped objects to be packaged, and a sealing and cutting device is arrang...

AI Technical Summary

Problems solved by technology

However, when the height difference is large, the object to be packaged will incline greatly when it is transferred between the conveyor belts, and it will be dumped. Offset, resulting in the sealing and cutting line of the film after heat shrinking is not in the middle of the object to be packaged, the packaging quality is poor and unsightly
