Description

Flexible packaging bag welding nozzle machine automatic feeding nozzle welding device

[technical field]

The utility model relates to an automatic nozzle feeding and welding device for the soft packaging bag welding nozzle machine used on the flexible packaging bag welding nozzle machine, especially used in the mouth socket of the soft packaging bag and the initial heat sealing station.

[Background technique]

At present, the mouth of the bag is located in the middle of the short side for filling and welding nozzles. The commonly used automatic filling and sealing machine for soft packaging bags is as shown in CN2452893. There is an automatic bagging device on the sealing station, the automatic bagging device includes a bag-taking transmission mechanism, a bag-clamping mechanism and a bagging slider mechanism; The bag is sucked from the bag rack, and then sent to the bag clamping and opening mechanism for clamping, and the opening of the bag is pulled, and the bagging slider mechanism will cover the bag with the opening of the bag on the nozzle, and weld it firmly through the welding nozzle mechanism. However, when the flexible packaging bag has an irregular shape or the opening of the flexible packaging bag is an oblique incision (such as a 45° oblique incision at the corner of the packaging bag), it is difficult for the above-mentioned bag taking and conveying mechanism to complete accurate transmission, and it is difficult for the opening mechanism to be accurate. When the mouth of the bag is pulled open, it is difficult for the bagging slider mechanism to accurately place the mouth of the bag on the nozzle, resulting in an increase in defective products. Therefore it is necessary to design a kind of feeding nozzle and welding nozzle device that can realize accurate socketing and primary heat sealing of the mouth of the flexible packaging bag when the flexible packaging bag is an irregular shape or the opening is an oblique incision.

[utility model content]

The purpose of this utility model is to design an automatic nozzle feeding and welding device for the flexible packaging bag welding nozzle machine used on the soft packaging bag welding nozzle socket socket and the initial heat sealing station, so that the flexible packaging bag When the shape is irregular or the opening is an oblique cut, it can realize accurate socketing and initial heat sealing between the nozzle and the mouth of the flexible package.

A soft packaging bag welding nozzle machine designed by the utility model automatically sends nozzles and welding nozzles. A suction cup is installed on the piston rod of the cylinder; a positioning mechanism is provided with a fixed positioning mold and a movable positioning mold closed with the fixed positioning mold, and the movable positioning mold is connected to the piston rod of a cylinder; There is a nozzle transmission mechanism between the mechanism and the positioning mechanism. The nozzle transmission mechanism is provided with a pneumatic finger connected to the piston rod of a cylinder fixed on the turntable; A welding nozzle mechanism is arranged, and the welding nozzle mechanism is a pair of heat-sealing molds split up and down.

The above-mentioned automatic tip welding device for the flexible packaging bag welding machine is characterized in that an electric heating device is installed in the positioning mold.

The above-mentioned automatic nozzle feeding and welding device for the flexible packaging bag welding machine is characterized in that the pair of heat sealing molds are respectively connected to the piston rods of a pair of split air cylinders.

Working principle and characteristics of the present utility model are described as follows:

On the socket and initial heat sealing station between the mouth of the nozzle and the mouth of the flexible package. The utility model takes the mouth out of the positioning mechanism and sends it into the opened bag mouth through the mouth conveying mechanism, and cancels the bag taking, bag feeding and bagging actions of the traditional welding mouth machine or sealing machine. Put it on the mouth. In the process of feeding the mouth of the bag, the flexible packaging bag is positioned on the pull mouth mechanism, so when the flexible packaging bag has an irregular shape or a diagonally cut opening, the mouth conveying mechanism can still accurately feed the mouth of the mouth; , because the chewing is relatively hard in texture and not easy to deform, so the process of taking the chewing, sending the chewing and sending the chewing into the mouth of the soft packaging bag of the utility model is better than that of the traditional welding nozzle machine or sealing machine. The bag process is much more reliable and easier to control. Therefore, the application range of the welding nozzle machine of the utility model is wider than that of the traditional welding nozzle machine or sealing machine, and it is easy to control and has a higher yield.

As a positioning mechanism, the positioning mold has a built-in heating device, which can achieve the purpose of preheating the nozzle during the clamping and positioning process of the nozzle, so as to ensure the smooth completion of the welding nozzle work of the welding nozzle mechanism.
