Abstract

The utility model relates to a machine for making bag of plastic film, which comprises a power device, a feed roller, a heat seal wheel and a paper-out wheel. An adjusting wheel which can be used for adjusting the tightness of a strap is arranged between the paper-out wheel, a support strap wheel 9 and the feed roller, a support belt leather wheel 5; a heat sealing wheel is provided with a plurality of nichrome heaters which can carry out intermittent heating and heat-sealing for the plastic film of heaters; a wrapup wheel which can run synchronously is arranged on the back side of the paper-out wheel; the side of the wrapup wheel is provided with a counter and a control switch. The utility model has the advantages of simple structure, large output, high quality, low cost and convenient operation.

Description

A kind of plastic film bag making machine

The utility model belongs to particularly a kind of bag making device that film is sealed of producing device of plastic film bag.Existing plastic film bag making machine, when work with pulling or riding, make a depression bar translation on the plate be depressed into electric hot plate, the book film that is clipped in is between the two sealed, and till this pressure will be maintained to always and seal, the time had been grown, make plastic sheeting fusing and disconnect, time has lacked, and heat-sealing is incessantly sealed blow-by.So the operator is in tension, long-time operation easily makes people's fatigue, and product quality is low, and speed is slow.And use the heat-sealing machine crank rod-type or relay control electromagnetic device, then owing to be to seal one by one to cut, effect and output are all lower.

United States Patent (USP) 3708377 discloses a kind of this machine of Bag Making Machine that is used for heat-sealable material and has constituted by going into material roller, heat-sealing wheel, output roller, transfer roller segmenting device and gathering-device, because of the heat seal process of this Bag Making Machine be by film supports on heat-sealing wheel, though can reach heat-sealing, but film is difficult to evenly with contacting of heating wire, to the higher and inaccessible high speed heat-sealing of the specification requirement of heater element.The segmenting device of this Bag Making Machine is a single layer cut, and also inaccessible high speed is received bag.And the cost of this machine is more expensive than imitating.

In order to overcome the shortcoming that above-mentioned prior art exists, the utility model provides a kind of bag making device of fast automatic heat sealing.

Plastic film bag making machine of the present utility model, comprise power set, feed roller 2, film volume 11, heat-sealing wheel 1, paper output wheel 8, it is characterized in that at paper output wheel 8, back-up belt 9 and feed roller 2, the adjustment wheel 3 that can adjust the belt degree of tightness is set between the back-up belt 5,3-30 bar nickel chromium triangle heating wire 16 is set on heat-sealing wheel, is interrupted heating by the rotor 17 of heat-sealing wheel shaft and the coupling apparatus 15 of lighting a fire, belt 10 tread support membranes are pushed down heat-sealing wheel and are reached the high-speed smooth heat-sealing, the synchronous operated winding wheel 4 of one energy is set in the back of paper output wheel 8, the spring 12 can regulate the film take-up radius is set on winding wheel 4, a counter 13 that can show rolling quantity is set, the driving lever 18 that can stir counter on the termination of winding wheel in a side of winding wheel 4.One relay 19 and one is set on the counter of winding wheel side can controls the controller 14 of power switch.

The utility model improves the structure of existing bag making device, adopt the strap clamp cycle type to carry out heat sealing, and the mode of cutting in the lump of collection synchronously, production efficiency improves, the big good product quality of output, easy and simple to handle, cost is low, this product one puts goods on the market, and will produce huge economic benefit and social benefit.

Below in conjunction with accompanying drawing the utility model is further described:

Fig. 1 is the utility model structure principle chart.

Fig. 2 is the schematic diagram of winding wheel of the present utility model.

Fig. 3 is the schematic diagram of heat-sealing wheel of the present utility model.

Among the figure: the 1st, heat-sealing wheel, the 2nd, feed roller, the 3rd, adjust wheel, the 4th, winding wheel, the 5,6,7, the 9th, the pulley of back-up belt, the 8th, paper output wheel, the 10th, belt, the 11st, film volume, the 12nd, spring, the 13rd, counter, the 14th, power switch controller, the 15th, igniting coupling apparatus, the 16th, the nickel chromium triangle heating wire, the 17th, the rotor that links to each other and continue conduction time between controlling with the heat-sealing wheel shaft, the 18th, driving lever, the 19th, relay.

After power set start, driving heat-sealing wheel and winding wheel rotates synchronously, film paper rolls out through pulley 5 from film, be pressed on feed roller 2 by belt 10, again through pulley 6, enter heat-sealing wheel 1, at this moment seal the wheel shaft upper rotor part and carry out regular energising igniting, make correspondingly heating and cooling of nickel chromium triangle heating wire 12 with igniting coupling apparatus 15.The film that enters heat-sealing wheel is connect one section ground for one section to be sealed, film after the heat-sealing is by pulley 7, enter paper output wheel 8, deliver to winding wheel 4 by pulley 9, pulling force size when at this moment the spring on the winding wheel 12 enters according to the film that has sealed, adjust the radius size of winding wheel, guarantee the heat-sealing line overlap of the heat sealing film that each is all, the driving lever 18 on the while winding wheel 4 is stirred counter 13 and is counted, when reaching certain number of plies, relay 19 automatic touch switch controllers 14 cut off electrical source of power, at this moment will receive the winding wheel of bag film and pull down, carry out cut paper, refill overhead winding wheel simultaneously, closed power switch works on.
