Improved portable plastic film jointing and sealing machine

The utility model relates to a kind of improved plastic wrapping bag sealer.

The sealing-in narrower in width of existing portable plastic film sealing maching when plastic bag sealing, often makes sealing part crumple or break easily, can't print additional on this narrow edge sealing and seal date expression, and this has just limited to the function of sealing maching; Existing sealing maching requirement sealing-in thing thickness can not be blocked up, and blocked up meeting is difficult to reach seal request because of the shortage of heat of machine, and can not the sealing-in laminated film.Because these deficiencies are very restricted the range of use of existing portable plastic film sealing maching.

But the purpose of this utility model is the plastic film packaging bag that will provide a kind of thickness of sealing-in material thicker, seal broad, and seals the novel portable sealing maching that also can print date and printed words.

The utility model is to implement like this:

Relay circuit in the original power supply control casket there are not the triac trigger circuit of mechanical contact instead, to improve its reliability and life-saving;

Change original sealing-in width 1.5-2MM into 8-10MM, and the sealing-in time changes 0.4-2 second second into from 0.2-1.5;

Be 200-400MM because the length of the work recess of this sealing maching increases, its labor aptitude is strengthened, promptly can adapt to the sealing of packaging bag of different size;

For the transient heating power with original machinery is increased to nearly 1KW from 0.3KW, and that body still keeps is small and light, then just make the profile of the voltage transformer of its adapted into strip, and adopt substandand E sections chip, change the diameter of enamel wire into 2.2MM from the 0.8MM of former fork-like farm tool used in ancient China, the efficient of voltage transformer is improved, and cal val descends, its output voltage is reduced to present 15V from the 22V of former fork-like farm tool used in ancient China;

Original sealing-in time rule was brought up to 0.4 second-2 seconds for 0.2-1.5 second.In addition the instantaneous temperature that seals of this machinery improves, then can be with the thickness thickening of plastic sheeting to be sealed, and the thickness of polyethylene foil that can sealing-in thickens to 0.4MM from the 0.03-0.3MM of former fork-like farm tool used in ancient China; To former fork-like farm tool used in ancient China can not sealing-in THIN COMPOSITE touch become can be below the sealing-in 0.2MM laminated film.

Because the improvement of above service conditions and function, make that the structure of this sealing maching is corresponding has done change.

Being about to original size that is located at the pressing plate Baltimore groove in the sealing maching pressure arm suitably enlarges, but make I-shaped cross-section press strip (the silaatic system in the former fork-like farm tool used in ancient China insertion groove, its shore hardness is 70 °) make press strip (the silaatic system of square-section into, its shore hardness is 45 ° ± 5 °), the middle part of this press strip has the type cylindrical hole, can insert the date of need printing and the type cylindrical piece of literal in the cylindrical hole.The elasticity of this kind press strip is very strong, so can directly insert in the pressing plate Baltimore groove, no longer needs to make the press strip of I-shaped cross-section, has also reduced productive costs thus.

Because require the operating temperature of this sealing maching higher, so but two kinds of nickel chromium triangle aluminium of adapted heating wire, its diameter has two kinds: a kind of is that diameter is 2MM, is that 5.4 ohm/meter, another kind are diameter 10MM than resistance, is 1 ohm/meter than resistance.Circular suspension member is mixed at the two ends of this heating wire, and smocking is on the hanging column at support concave shaped portion two ends.These two kinds of heating wire are selected for use during for corresponding different seal, sealing materials and different-thickness film.The heating wire hanging column that this and former machine difference are this machines is connected on two U-shaped spring leafs, when the big adstante febre of electric current can be for the retractility of buffering heating wire; And a U-shaped flat spring is adorned in the rear end of a former machine organic block, and the other end is fixed; So the front end of existing sealing maching be arc and the rear end is square; The two ends of the sealing maching after the improvement all are square.

The handle that former machine is located at the pressure arm upper front end is columniform, and the sealing maching handle after improving is because thickening, increasing of seal just needs the contact surface of swelled handle and palm, and to alleviate the pressure of palmar aspect, therefore newly the hand grip control of machine becomes oblong.

By above-mentioned improvement, this later-model portable plastic film sealing maching still keeps having little, the lightweight characteristics of volume, is applicable to and seals length at 200-400MM, width is in the sealing-in of the plastic sheeting of 2-10MM, and on sealing, can directly print date and literal, become a kind of small-sized multi-functional sealing maching.
