Abstract

The utility model relates to packaging machinery, a full-automatic stretching wrapping machine. A thin film lifting device for lifting motor actuation, an electrical apparatus control cabinet, a thin film pre-stretching device and a rotary disk rotating device for rotary disk motor actuation are arranged on the engine base, wherein the rotary disk is provided with a goods delivery device and a device which can automatically film and slit film. The utility model is added a tray delivery device, a film crush-cutting device, a film fending device, a film drawing device, an adhesive shear device and an adhesive shear heating device on the basis of the prior semi-automatic stretching wrapping machine, and thereby the tray stretching wrapping machine is improved to full-automatic wrapping from the prior semi-automatic wrapping. Therefore, the wrapping efficiency is enhanced without filming and film cutting by labor, manual effort is saved and full-automatic unmanned operation is achieved. The thin film end is bond by heating without tape adhesion, thereby avoiding thin film natural loosing after wrapping and achieving reliable quality.

Description

Full automaticity stretches and twines wrapping machine

Technical field:

The utility model belongs to the package packing machine field, is specifically related to the stretching winding package equipment of pallet class article.

Background technology:

In the packing of pallet class article, owing to be subjected to the restriction of woodwork packing export quarantine and reduce timber resources, the needs of developing a circular economy, wooden case, carton package are stretched gradually and twine and the shrink wrapping technical approach replaces; Promptly having reduced lumber consumption, reduced packing cost again, is domestic and international materials circulation, realizes the commonplace a kind of emerging technology of the package of " door t door " shipping employing.But, twine wrapping machine owing to stretch at present, must manually stretch film be fixed on the packaged object and pack, after packing finishes, also need artificial disconnected film blended rubber band to cement, as the described stretching winding-packing machine of Chinese patent 95232167.x, realized mechanical packaging, but still existing packaging efficiency low, the cost height can not realize packing the shortcoming of full-automatic unmannedization.

Summary of the invention:

The purpose of the present utility model is to overcome above-mentioned stretching to twine the defective that wrapping machine exists, and provides a kind of full automaticity to stretch and twines wrapping machine, realizes full-automatic unmannedization of baling line, improves packaging efficiency, saves manpower, reduces packing cost.

The technical scheme that the utility model is adopted for achieving the above object is: full automaticity stretches and twines wrapping machine, and thin film elevating device, electric control cabinet and film pre-stretching device that lifting motor drives are housed on the support; The dial rotation device that rotary tray motor drives is installed on the support, apparatus for transporting freight is installed on the rotating disk and goes up film, sticking film cutting apparatus automatically.

Described apparatus for transporting freight connects transmission parts for transmitting motor, and transmission parts is transfer roller or transmission parts such as transmission chain or feed belt.

The described film, sticking film cutting apparatus automatically gone up is fixedly press mold cutting knife and two retaining film bars on the rotating disk, and two retaining film bars connect by film and start speed change fork two rollers, starts the speed change fork and is connected with film prestension mechanism big path roller.

On the described dial rotation device rotary brush is installed.

Described bonder is that bonding cutting is contained on the support, and bonding cutting is equipped with the bonding temperature booster of cutting, and bonding cutting with the bonding cylinder of cutting is connected.

Described film prestension assembling device is connected with the membrane cylinder, and the membrane cylinder is installed on the stretch film crane.

The utility model stretches at former S. A. and twines on the basis of wrapping machine, has increased the pallet conveyer; The crush-cutting film device; The retaining film device, film drawing device, bonding device and the bonding heating arrangement of cutting cut, pallet is stretched twining wrapping machine is fully-automatic packaging by the lifting of S. A. packing.Thereby the raising packaging efficiency need not manually to go up film and disconnected film, saves manpower, has realized full-automatic unmannedization operation.The terminal employing of film adds heat bonding, need not to use adhesive tape bonding, avoided the packing rear film to get loose reliable in quality naturally.

The specific embodiment:

Full automaticity pallet as shown in Figure 1, 2, 3 stretches and twines wrapping machine, motor, electric control cabinet 17 and film stretching device are housed on the support, film stretching device 20 is connected with membrane cylinder 7, the membrane cylinder is installed on the stretch film crane, the dial rotation device that rotary tray motor 4 drives is installed on the support, rotary brush 21 also is installed on the dial rotation device, apparatus for transporting freight is installed on the rotating disk 18 and goes up film, film cutting apparatus automatically.Apparatus for transporting freight connects transmission parts 2 for transmitting motor, and transmission parts 2 is illustrated in figure 3 as transfer roller, also can be transmission parts such as transmission chain or feed belt.Automatically go up film, film cutting apparatus and be on the rotating disk 18 fixedly press mold cutting knife 12 and two retaining film bars 14, two retaining film bars and connect and start 5 liang of rollers of speed change forks, start speed change fork and film stretching mechanism by greatly directly roller 8, path roller 9 are connected.Bonder also is housed on the support in addition, and it is cut 16 and is contained on the turntable for bonding, and bonding cutting is equipped with the bonding temperature booster 22 of cutting, and bonding cutting with the bonding cylinder 15 of cutting is connected.

During work, when goods 3 by sign indicating number behind the good buttress, passed by the front end travel line and to come, after Photoelectric Detection, pallet transmits motor 1 and starts, and goods is reached on the rotating disk transfer roller 2, stops on the multiple package position after after testing again; Rotary tray motor 4 begins to start, and drives rotating disk 18 and rotates in the direction of the clock; Press mold cutting knife 12 rotates with rotating disk 18 after the dial rotation, and pulling starts speed change fork 5 simultaneously, starts and puts film change speed motor 6, and prestension mechanism 20 beginning prestretchings over film; This makes film by the width of cloth that broadens in a narrow margin, and carries out the spiral winding by the prior setting number of turns, and 10 beginnings of prestension lifting motor more from top to bottom, are finished the whole winding cycle from bottom to up; Membrane cylinder 7 will be depressed by the wide-range film that prestension mechanism 20 pulls out, and make by the film 19 of prestension in starting 5 liang of rollers of speed change fork, be become in a narrow margin by wide cut again, be rotated further a circle after; Retaining film bar 14 is rotated by retaining film bar motor 13 and lifts, and blocks film in a narrow margin; Electric pushrod 11 lifts, the compacted film in a narrow margin of packing before unclamping; Bondingly cut 16 and under bonding promotion of cutting cylinder 15, move ahead, carry out near the interlude of film in a narrow margin that is blocked by two retaining film bars 14 bonding, will start simultaneously speed change fork 5 bonded assemblys in a narrow margin film push press mold cutting knife 12 stations again to; Electric pushrod 11 is fallen, press mold cutting knife 12 once more will by retaining film bar 14 bonded assemblys in a narrow margin film cut off and compress, for the road packing is ready down; Retaining film motor 13 throw-over catch film bars 14 unclamp the film in a narrow margin that is blocked, and spring back on the pallet, and pallet transmits motor 1 and starts once more, and goods is spread out of multiple package position, finishes full-automatic unmannedization operation.
