Packaging machine

Abstract

The invention relates to the technical field of product packaging, and particularly discloses a packaging machine which comprises a support, a clamping mechanism, an air exhausting mechanism and a packaging mechanism. The air exhausting mechanism comprises an air cylinder and a screw rod rotatably connected with the air cylinder; the screw rod comprises an upper screw rod and a lower screw rod with opposite threaded directions; a piston is in threaded connection onto the lower screw rod and is slidably connected with the air cylinder; a vent hole is formed in the air cylinder; a support tableis arranged under the vent hole; a converter plate is hinged to the right end of the support table; a torsional spring is arranged between the support table and the converter plate; a conveyor belt isarranged under the converter plate; the packaging mechanism comprises a connecting rod and a heating block; the connecting rod is in threaded connection with the upper screw rod; the clamping mechanism comprises an elastic telescopic rod and a clamping block connected fixedly; a through hole is formed in the clamping block; a brake rod is fixedly connected onto the elastic telescopic rod; and a fastener is arranged between the connecting rod and the clamping block. By adopting the scheme, a packaging bag can be clamped and straightened so as to be used for packaging, and the occurrence of thephenomenon that a worker is easy to get a burn when carrying out the packaging bag straightening process is avoided.

Description

technical field [0001] The invention relates to the technical field of article packaging, and specifically discloses a packaging machine. Background technique [0002] Vacuum packaging, also known as decompression packaging, is to extract all the air in the packaging container and seal it to maintain a high degree of decompression in the bag. The scarcity of air is equivalent to the effect of low oxygen, so that microorganisms have no living conditions, so as to achieve fresh fruit and no disease. purpose of occurrence. At present, vacuum packaging in plastic bags, aluminum foil packaging, glassware, plastic and its composite material packaging are currently used. Packaging materials can be selected according to the type of items. Some rare handicrafts handed down from generation to generation, such as clay sculptures, must be stored in vacuum during storage. However, the existing vacuum packaging machines generally put the clay sculptures into the packaging bags artificia...

Problems solved by technology

In the prior art, when packaging, it is necessary for people to stack the packaging bags neatly and then hold the packaging bags for packaging, which increases the labor intensity of the workers; when the workers hold the packaging bags for packaging, it is easy to contact with the heating block of the packaging packaging bag and cause burns. Therefore, the risk factor of workers' working environment is high; at the same time, the temperature of the hot-melt part of the packaging bag that has just been hot-melt sealed is relatively high, and workers are prone to burns when they manually pick up the packaging bags.
