Abstract

The utility model discloses a drawing and wrapping type packaging machine, composed of a machine base 21, a motor 10, a motor 11, a turn table 8, a guide rail 20 and a thin film drawing device 18. The motor 10, the motor 11, the turn table 8 and the guide rail 20 are arranged on the machine base, and the thin film drawing device 18 is dragged by the motor 11 and assembled on the guide rail 20. The utility model is characterized in that the structure of the thin film drawing device 18 is that a supporting frame 25 is matched with the guide rail 20, and the supporting frame 25 is provided with a speed transforming transmission 24 and a motor 4 which is used for regulating the rotary speeds of rubber rollers 5 and 6. The utility model can be regulated to the optimum state according to the practical drawing rate of the thin film, and the ultimate potential of the thin film is fully exerted to achieve the optimal drawing effect. The goods can not be damaged, the thin film can not be torn, and the packaging cost of the goods can be reduced.

Description

The stretching winding-packing machine

The utility model has related to a kind of package packing machine, especially a kind of stretching winding-packing machine.

The traditional stretching winding-packing machine of many at present employings: sealed film bobbin braking limits the expansion of film, relies on the power of turntable rotation, the stretching of realization film.As Singapore TANTRACO company, 1500 types that Italy ROBOPAC produces and China Shanghai Charlie company etc., this method, do not allow high elongation, because too high stretching can make cargo rein in bad or the goods displacement, simultaneously, it is that transverse width reduces (as Fig. 1) film stretching rate and can only reach 10～55% that the film between film and the cargo can form under the effect of tensile force that serious fabric width shrinks, can not bring into play the potentiality of the limit of film, reach the optimum stretch effect.

The purpose of this utility model provide a kind of can be according to the actual extensibility of film, equipment is adjusted into the optimum stretch state, give full play to the limit potentiality of film, reach the optimum stretch effect, and make goods rein in bad or the goods displacement when not making film stretching, do not tear film, the minimum stretching winding-packing machine that the packing cost of each goods is fallen.

Technical solution of the present utility model is: a kind of stretching winding-packing machine, comprise: support 21, motor 10 is housed on the support 21, motor 10 connects driving device 22, driving device 22 switches through platform 8, guide rail 20 and motor 11 also are housed on the support 21, motor 11 chain link drivings device 14, chain gearing 14 is connected to film stretching device 18, it is characterized in that: the structure of described film stretching device 18 is: the bearing support 25 and described guide rail 20 couplings affixed with chain on the chain gearing 14, the film platform 16 that can adjust degree of tightness is housed in the bearing support 25, goes back bearing rubber roll 5 and rubber roll 6 are housed, motor 4 is housed on the bearing support 25, motor 4 joins with variable-speed drive 24, the output shaft of variable-speed drive 24 connects with rubber roll 5, and rubber roll 5 is paid with rubber roll 6 usefulness transmissions and joined, and the rotating speed of rubber roll 5 is higher than the rotating speed of rubber roll 6.

The utility model compared with prior art has: can equipment be adjusted into the optimum stretch state according to the actual extensibility of film, give full play to the limit potentiality of film, reach the optimum stretch effect, and goods is not impaired, does not tear film, reduces the advantage of goods packing cost.

Fig. 1 is a prior art stretched portion structural representation;

Fig. 2 is the utility model embodiment stretched portion structural representation;

Fig. 3 is that the utility model embodiment complete machine master looks scheme drawing;

Fig. 4 is the utility model embodiment complete machine schematic top plan view;

Fig. 5 is that scheme drawing is looked on the utility model embodiment complete machine left side.

As Fig. 2,3,4, shown in 5, motor 10 is housed on the support 21, motor 10 drives turntable 8 rotations by chain gearing 22, welding or Bolt Connection guide rail 20 on the support 21, and be fixed with shell, dress electric controller 17 on the shell, Bolt Connection motor 11 on the support 21, motor 11 connects by

sprocket wheel

12,13 and the chain gearing 14 formed of chain, the two ends of chain be welded in film and draw the hinged-support 19 on the refreshing device 18 hinged, the structure of film stretching device 18 is: be welded with the framework of adorning pulley 23 with chain pivotally attached bearing support 25, pulley 23 matches with guide rail 20, the film platform 16 of holddown spring 2 and control hand wheel 1 adjusting degree of tightness is housed in the bearing support 25, bolt is connected to motor 4 on the bearing support 25, motor 4 joins with speed-changing gear box 24, the output shaft of change speed gear box 24 and rubber roll 5 join, rubber roll 5 adopts gear coupling with rubber roll 6, the rotating

speed rubber roll

5 and 6 that the rotating speed of rubber roll 5 is higher than rubber roll 6 all adopts bearing to connect with bearing support 25, on the bearing support 25 collision block is housed, cooperate with the travel switch of control motor 11 on being contained in the guide rail shell, make chain gearing 14 drag film stretching device 18 and on guide rail 20, make straight-line motion up and down reciprocatingly.Continuous pile goods 15 together with various lengths during work places on the turntable 8, film is contained in and makes on the film platform 16 that film is walked around rubber roll 6, rubber roll 5 twines on goods, turn control hand wheel 1 holddown spring 2 produces the spin friction resistance, makes film realize stretching for the first time under the effect of pulling force; The film 3 that is stretched for the first time for the second time stretches 7 through rubber roll 5 and rubber roll 6 generations again, change speed gear box 24 output speed scopes are less than or equal turntable 8 rotating speeds, when rotating speed can be realized stretching 9 for the third time during less than turntable 8 rotating speeds, owing to adopted pulling method three times, 100%～300% extensibility can realize stretching, the electricity of the fabric width of film contraction simultaneously can reduce to minimum, this is because the high strength draw stage only occurs between two rubber rolls that are stretched for the second time, thereby avoided film to tear, goods is shifted and is reined in bad phenomenon, makes film obtain peak use rate.This draws the film of electric rate to have more comformability to tool 200～600%, finishes packing thereby film stretching device 18 rotating speed of straight-line speed and turntable 8 on guide rail is complementary.
