Embodiment

[0016] A four-nozzle mouth bonding device for a film-lined packaging bag, including a lateral movement mechanism 1, a longitudinal movement mechanism 2, a hot-melt glue sprayer 3 and a nozzle mechanism 4, such as figure 1 , the lateral movement mechanism 1 includes a servo motor, a synchronous belt pulley group, and a frame bracket. The frame body bracket is provided with a nozzle mechanism 4. The servo motor drives the frame body bracket through the synchronous pulley group, and the lateral movement mechanism 1 drives the nozzle mechanism 4 to move laterally. The distance is the length of the glue path required by the mouth of the bag; the longitudinal movement mechanism 2 includes a longitudinal cylinder, the base of the longitudinal cylinder is connected to the frame support, and the longitudinal movement mechanism 2 is stretched and stretched by the longitudinal cylinder to complete the nozzle mechanism 4 longitudinally extending into the mouth of the bag or exiting Pocket ...

Abstract

The invention provides a four-nozzle mouth adhesion device for a film package bags with a lining. The four-nozzle mouth adhesion device comprises a transverse moving mechanism, a longitudinal moving mechanism, a hot melt adhesive ejection machine and nozzle mechanisms, wherein each nozzle mechanism comprises an aeration one-way valve, an adhesive ejection head body, a nozzle needle tube, a heating rod, a thermal-insulating connecting sleeve, a cylinder mounting rack and a micro-cylinder; compressed air is provided into the aeration one-way valves through air pumps; channels through which an adhesive or compressed air passes are formed in the adhesive ejection head bodies; nozzle needle tube mounting holes are formed in the front parts of the adhesive ejection head bodies; piston holes are formed in the rear parts of the adhesive ejection head bodies; heating rod mounting holes are formed in two sides of the piston holes; the bases of the micro cylinders are arranged on cylinder mounting racks; piston rods of the micro cylinders are connected with the heating rods through the thermal-insulating connecting sleeves. Due to design of a piston mechanism for controlling the surplus adhesives of the nozzle needle tubes when adhesive ejection is started and stopped, the adhesive outlets of the nozzle needle tubes are controlled to prevent the surplus adhesives from overflowing outside bag mouths, the outer layers of the mouths of inner and outer bags can be adhered together, and inner bags can be opened easily.

Description

technical field [0001] The invention relates to a four-nozzle mouth bonding device for film-lined packaging bags. Background technique [0002] Packaging bags make it easy to transport and store goods during production and circulation, and are widely used in daily life and industrial production. As an important type of packaging bag, film packaging bag with inner liner is one of the most commonly used items in production or production. However, in the production of the prior art, when the glue is sprayed, due to the inability to control the residual glue when the needle is started and stopped, more glue will be left on the mouth of the bag, causing the mouth of the bag to stick. , The suction cup of the automatic filling machine cannot suck the opening of the bag and affect the normal filling operation. Contents of the invention [0003] The purpose of the present invention is to provide a four-nozzle mouth bonding device for film-lined packaging bags, which can prevent ...
