In the utility model, adopting photo-electric control is that Bag Making Machine has improved automaticity, and improved the production efficiency of bag, servomotor and Programmable Logic Controller matches simultaneously, the accurate control long for the plastic film bag bag provides guarantee, the installation of its photocell eye, it is long to control bag, can detect the colour code of making the printing bag again, the setting of welding by both sides cutter, provide convenience for making different bag kinds, four feeding rollers in that cradle is installed have improved the great efficient of upward producing for making a flat mouthful refuse bag, are four times of common Bag Making Machine, the stepper motor of installing at the rolling frame simultaneously is for the rewinding of plastic film bag has also improved automaticity.According to the photo-electric control automatic bag making machine of the utility model design motif made, will bring positive result of use for vast manufacturing plastic film bag industry.

[description of drawings]

The utility model has following accompanying drawing:

Fig. 1 is a structural representation of the present utility model.

Number in the figure 2 is a feeding roller.

[specific embodiment]

Accompanying drawing has been represented structure of the present utility model and embodiment, describes each relevant details of embodiment below more in conjunction with the accompanying drawings in detail.This photo-electric control automatic bag making machine; include frame 13, cradle 15, weldering cutter 4, dancer rools 5, cutting knife 7 and rolling frame 9; described weldering cutter 4 and cutting knife 7 are installed in respectively on the body 13; be to be equipped with on the cradle 15 optoelectronic switch 14; bamboo curtain splint 16 lower ends have or not film on the cradle 15 to detect; if do not detect the film of bamboo curtain splint 16 lower ends, promptly notify Programmable Logic Controller to show shutdown.The frame 13 in described weldering cutter 4 the place aheads is provided with photocell eye 3, this photocell eye 3 is when the production of machinery refuse bag, it is long to be used for the control bag, when on machine, producing various printings bag, be used to detect the colour code of printing bag, the below of described dancer rools 5 is provided with servomotor 11, described servomotor 11 is in transmission connection with drawing material squeegee 6, when machine startup, cooperate to draw and expect that squeegee 6 is used for intermittently being fed to cutting knife 7 and cuts off, described body 13 is provided with the Programmable Logic Controller (not shown), described servomotor 11, optoelectronic switch 14 and photocell eye 3 all are electrically connected with Programmable Logic Controller, produce the refuse plastic bag film, with the omnidistance control of Programmable Logic Controller, its control bag long precision is accurate, when producing the printing bag, can accurately control the colour code position of printing bag, described weldering cutter 4 is the welding by both sides cutter, one side is single bonding wire weldering cutter, and another side is two bonding wire weldering cuttves; Because when making plastic film bag, some bag is planted need be with single bonding wire envelope, some bag is planted need be with two bonding wire envelopes, to weld cutter 4 is made into two-sided, in order to satisfy the demand that different bags are planted, do not need to change weldering cutter 4 in addition, as long as it is fixing with the locking device (not shown) by the direction of rotating shaft Rotate 180 degree to weld cutter 4; Four volume film rollers 1 can be installed on the described cradle 15, the installation of these four volume film rollers 1, be used when producing refuse bag specially, be equipped with two weldering cuttves 4 on the frame 13, to improve the production efficiency of refuse bag, the raising of its efficient is four times of original technology, but when producing the printing bag, only need utilize a volume film roller to produce; Described rolling frame 9 is provided with servomotor 8, and the feeding belt on described servomotor 8 and the rolling frame 9 is in transmission connection, and the setting of this servomotor had replaced the slow rhythm production of artificial rewinding in the past, for the production line of plastic film bag has been saved the rewinding time.When flat mouthful of refuse bag produced in the utility model work, four volume Membrane covers are being rolled up on the film roller, machine, when the optoelectronic switch 14 on the cradle 15 detects the plastic sheeting of bamboo curtain splint 16 ends, the notice Programmable Logic Controller, order main motor 12 to start, when the plastic sheeting bag length below process photocell eye 3 reached and sets value on the Programmable Logic Controller, main motor 12 drove weldering cutter 4 and presses down by machine driving, plastic film bag is carried out envelope, after envelope is finished, intermittently be sent to cutting knife 7 belows by servomotor 11, cutting knife 7 is also because main motor 12 passes through the machine driving incision, plastic film bag is cut off, the finished bag that cuts off send on the rolling frame 9, when running up to a certain degree, drives feeding belt by servomotor 8 finished bag is seen off, whole process is accomplished without any letup, and is very convenient.When producing the printing bag, just utilize in four volume film rollers, photocell eye 3 is used to detect the colour code on the printing bag, and other process is identical with the production refuse bag.The of the present utility model design successfully for the production of plastic film bag has improved great efficient, compared with prior art, has substantive distinguishing features and progress.
