Abstract

The invention discloses a film automatic nozzle-adding device which comprises an upper film conveying belt and a lower film conveying belt. The upper film conveying belt comprises a first conveying roll set for conveying a film on the upper portion of a bag body, the lower film conveying belt comprises a second conveying roll set for conveying a film on the lower portion of the bag body, and the first conveying roll set and the second conveying roll set both comprise two conveying rolls at intervals so as to be used for conveying the double-layer films. A tensioning roll set, a punching device and a nozzle-adding heat sealing knife are sequentially arranged on the upper film conveying belt, and the nozzle-adding heat sealing knife is provided with a nozzle cover through an automatic nozzle abutting-against device. The longitudinal automatic nozzle-adding device for the film is adopted, bag making and nozzle-adding separation can be reduced, a working process is simplified, and labor costs are reduced.

Description

Film adds mouth device automatically

Technical field

The present invention relates to a kind of to adding the device of mouth on film.

Background technology

Summary of the invention

For the deficiencies in the prior art, the invention provides the device that longitudinally automatically adds mouth for film, reduced bag and added mouth segregation phenomenon, easy workflow, saves labour costs.

The present invention is achieved through the following technical solutions: film adds mouth device automatically, comprise upper film conveyer belt and lower film conveyer belt, described upper film conveyer belt comprises the first transfer roller group for delivery of bag upper film, described lower film conveyer belt comprises the second transfer roller group for delivery of bag lower film, described the first transfer roller group and described the second transfer roller group all comprise two spaced conveying rollers, for carrying double-deck film, in described the first transfer roller group and described the second transfer roller group rear, be provided with for the thin press roll component of film and the drive roll for delivery of film of closing of bilayer, described drive roll drives by motor, on described upper film conveyer belt, arrange and be disposed with idler roller group, hole punched device, add mouth hot knife, the described mouth hot knife that adds provides mouth lid by the device of automatically answering back, after described upper film conveyer belt, described lower film conveyer belt intersection rear is provided for top and the bottom film to carry out the bag compression framework of press seal one-tenth bag, described idler roller group comprises the first cylinder and the installing plate being connected with described the first cylinder stopper rod, on described installing plate, be arranged at intervals with two groups of guide rollers for leading, also comprise the PLC controller of controlling described the first cylinder, described first is positioned at and adds mouth hot knife rear the sensor that detects film rate of tension is set at described upper film conveyer belt, described PLC controller is connected with described sensor electrical.

In technique scheme, described PLC controller is connected with the motor that drives described drive roll.

In technique scheme, the described device of automatically answering back comprises automatic capstan and adds mouth track, described automatic capstan with described in add mouth track and be connected, by add mouth track with described in add mouth hot knife and be connected.

The present invention has following beneficial effect: the present invention adopts film longitudinally automatically to add the device of mouth, has reduced bag and has added mouth segregation phenomenon, and easy workflow, saves labour costs.

Accompanying drawing explanation

Fig. 1 is structural representation of the present invention.

Fig. 2 is the structural representation that the present invention adds mouth pipeline.

Fig. 3 is the structural representation of the automatic capstan of the present invention.

The specific embodiment

Below the present invention is described in further detail, in the present embodiment, dotted line represents electrical connection, referring to Fig. 1 to Fig. 3, film adds mouth device automatically, comprise upper film conveyer belt and lower film conveyer belt, described upper film conveyer belt comprises the first transfer roller group 1 for delivery of bag upper film, described lower film conveyer belt comprises the second transfer roller group 2 for delivery of bag lower film, described the first transfer roller group 1 and described the second transfer roller group 2 all comprise two spaced conveying rollers, for carrying double-deck film, in described the first transfer roller group 1 and described the second transfer roller group 2 rears, be provided with for the thin press roll component 9 of film and the drive roll 91 for delivery of film of closing of bilayer, described drive roll 91 drives by motor, on described upper film conveyer belt, arrange and be disposed with idler roller group 8, hole punched device 3, add mouth hot knife 5, the described mouth hot knife 5 that adds provides mouth lid by the device 4 of automatically answering back, after described upper film conveyer belt, described lower film conveyer belt intersection rear is provided for top and the bottom film to carry out the bag compression framework 7 of press seal one-tenth bag, described idler roller group 8 comprises the first cylinder 80 and the installing plate 81 being connected with described the first cylinder stopper rod, on described installing plate 81, be arranged at intervals with two groups of guide rollers 82 for leading, when film longitudinally unreels, upper film is carried out to punching by hole punched device 3, after upper film surface is by punching, move to and add mouth hot knife 5 positions, the base 50 that adds mouth hot knife 5 is headed in film circular hole, by the envelope cutter 51 that adds mouth hot knife 5, film and base are heated, realize the connection of mouth lid and upper film.After upper film adds mouth and completes again by the pressure roller 6 in intersection upper film and lower film laminating, then by bag compression framework 7, upper and lower thin films are made to bag.

Also comprise the PLC controller 10 of controlling described the first cylinder 80, described first is positioned at and adds mouth hot knife 5 rears the sensor 11 that detects film rate of tension is set at described upper film conveyer belt, and described PLC controller 10 and described sensor 11 are electrically connected.Described PLC controller is connected with the motor that drives described drive roll 91.In the process of continuous bag, owing to having, add mouth hot knife 5 and heat film to add the technique of mouth, at continuous heating rear film, easily appearing at the hypodynamic problem of tensioning on roller occurs, therefore by sensor 11, judge the tensioning degree of film, when rate of tension is not enough, PLC controller control motor stops driving drive roll 91, and drive the first cylinder 80 piston rods descending, drive the guide roller 82 on installing plate 81 descending again film is carried out to tensioning (tensioning rear motor returns to former driving power), can in the situation that not needing workman to guard, automatically realize the tensioning of film.

The described device 4 of automatically answering back comprises automatic capstan 41 and adds mouth track 40, described automatic capstan 41 with described in add mouth track 40 and be connected, by add mouth track 40 with described in add mouth hot knife 5 and be connected.Automatically capstan utilizes chassis delineation substructure model, and Jiang Zuigai sends into and adds mouth track 40, and the mouth lid adding in mouth track 40 slips in the base 50 that adds mouth hot knife 5 automatically.
