Abstract

The invention provides a plastic bag constant-volume inflating device, which comprises a pressure stabilizing inflation device and a plastic bag opening suction opening and heat sealing device. The input end of a inflation control valve is connected with an air inlet pipeline, and the output end of the inflation control valve is connected with a pressure stabilizing device; the output end of the pressure stabilizing device is connected with an electromagnetic valve; the output end of the electromagnetic valve is connected with an inflation device; and the output end of the inflation device isconnected with a plastic bag opening opened through the plastic bag opening suction opening and heat sealing device through a needle tube of a vacuumizing inflation needle tube telescopic device. Theplastic bag opening suction opening and heat sealing device is provided with a plurality of rubber vacuum suction cups through a vacuum generator, the suction cups are sequentially arranged on the upper side and the lower side of the plastic bag opening in a face-to-face mode, and air cylinders are installed on suction cup supports respectively to control the supports to reciprocate. A PLC (Programmable Logic Controller) as well as the pressure stabilizing inflation device and the plastic bag opening sucking opening and heat sealing device which are connected with the PLC are arranged; and thedevice is simple in structure, effectively achieves the purposes of continuously controlling the pressure in the container to be stable, automatically sucking and opening the plastic bag opening, vacuumizing, constant-volume filling and heat sealing, and is safe and reliable in work and high in efficiency.

Description

technical field [0001] The invention relates to a fixed-volume inflation device for plastic bags. Background technique [0002] When the plastic bag in the prior art is inflated, the gas in the gas storage bottle is filled into the plastic bag through the gas pipeline. During this process, not only the volume of the filled gas is difficult to control, but also the filled gas cannot be permanently stored. Contents of the invention [0003] The purpose of the present invention is to provide a constant volume inflation device for plastic bags, which can achieve the purpose of continuous control of the pressure stability in the container and the automatic suction opening of the plastic bag opening, vacuum pumping, constant volume filling and heat sealing. It is not only safe and reliable , and high efficiency. [0004] To achieve the above object, the present invention adopts the following technical solutions: [0005] A constant-volume inflation device for plastic bags comp...
