The specific embodiment
As shown in Figure 1 and Figure 2, the utility model bag and capper comprise frame 1, power source special 5 ', nonshared control unit 5, heat sealing device and transmission device 6 and main tie 9, equalizer bar 10; The heat sealing device comprises movable casting die 2, fixedly casting die 3 and heating wire, heating wire chest expander 4; Movable casting die 2 is provided with cutter 11 and blade 7, is provided with pedal frame 8 in the transmission device.
As shown in Figure 3, Figure 4, it discloses labor-saving structure transmission device 6 of the present utility model, and the operation of such machine of prior art is required great effort very much, therefore designs the labor-saving structure of a practicality, is worth very big.Structure of the present utility model is, under the effect of reset tension spring, the angle that total is in 63 of reset mode, stressed member 62 and stressed members probably is 90 degree, the A point is elevated to the extreme higher position, take the movable casting die 2 of heat seal structure to vertex by main tie, make movable casting die 2 and fixing 3 opening-like attitudes of casting die.When the operator steps on pin and steps frame, lower link bar 67 is toward drop-down, by stressed member 66 connecting rod 65 is drawn to the right, along with the application force of connecting rod 65, the angle that stressed member 62 and stressed member are 63 becomes greatly thereupon, when the angle change is spent to about 175 greatly, movable and fixedly casting die be in identical state, at this moment as long as connecting rod 65 has slight pulling force, promptly have powerful expansionary force between A point and locating point B, by main tie drive activity casting die 2 to fixing casting die 3 adequate closures realization heat seal.This is simple and practical, very laborsaving.
Figure 5 shows that fixedly casting die of middle part dimpling that the utility model can adjust the dimpling amount arbitrarily.Its movable casting die 2 general fine aluminum section bars that adopt are made, and its driving surface is the silaatic 13 of lower end; When work movable casting die 2 press down, require whole piece silaatic 13 and fixedly casting die 3 is parallel identical, this is optimal situation.Because the pressure of movable casting die 2 relies on the pull bar 9 on both sides, and need certain pressure, and during the work of historical facts or anecdotes border, the metaboly of the movable casting die more than 2 or the stressed bending that makes progress in the middle part of little the appearance, middle part pressure is diminished, and the result makes the heat seal of product both sides respond well and middle part heat seal effect is bad.Therefore, middle part of this machinery requirement curved fixedly casting die of dimpling that makes progress cooperates with it.
Present fixedly casting die adopts a section bar to break into the middle part bending by manual modes such as hammers and uses.Because it is very high that this dimpling amount requires, for example, when casting die length was 65 centimetres, its dimpling amount required to 30C, so this structure and mode are difficult to reach requirement, and the control of machine difficult quality.What the utility model adopted is fixedly casting die of a normalized middle part micro-convex structure.It can adjust its dimpling amount according to actual needs arbitrarily, and movable casting die 2 and fixing casting die 3 is identical just right when making machine works, obtains good heat seal effect in whole heat seal scope.Also make things convenient for and control the conformability of mechanical product quality by the gross.Structure such as Fig. 5, fixedly casting die 3 adopts two blocks of section bars 31,32 up and down, section bar below it is harder, upper sectional material takes second place, middle part between two section bars is lined with the hard thing 33 of the thickness sheetmetal consistent with requirement dimpling amount, two ends are fastening with two section bars with screw, and fastening back lower sectional material keeps the indeformable upper sectional material of straight flange then to be the camber shape of middle part dimpling.This structure reaches technical requirements easily, controls the conformability of entire block easily.
The utility model also is provided with adjustable time voice prompting tripping device.The pedal frame because the operation of similar machine normally tramps with one's feet down starts fine motion or electronic switch when making movable casting die and fixedly casting die fully coincide automatically, makes the heating wire energising heat the realization heat seal.The process of heating wire energising heating is indicated by indicator lamp, and the operator must supervise and show that this indicator lamp operates.From the angle of production efficiency, wish (indicator lamp just extinguishes) rapid tripping (relieving pedal frame) when heating wire just finishes to switch on certainly, take out sealed bag immediately.But still very high, film heat seal place of its temperature still was in the hot melt state when in fact heating wire had just cut off the power supply, so at this moment immediately tripping and film heat seal place and heating wire are dispelled the heat to the fixedly casting die of aluminium matter manufacturing by the high temperature adhesive plaster can tripping after cooling off, and the length of this " pressurize " time is relevant with the thickness and the operating temperature of film, sometimes need reach 6~7 seconds, need the operator to know what's what, determine at random.If the time is oversize, production efficiency is low, too short then out of reach mass effect.Be difficult to control the conformability of product design.
The utility model has designed the electronics sound tripping prompt facility of an adjustable time.Adjust " pressurize " time before the operation according to actual needs, the operator need not prison and shows indicator lamp, need not to estimate " pressurize " time, only need hear " " just tripping of electronics sound.Make each heat sealed time unanimity, the temperature traverse unanimity has so just guaranteed the conformability of product design.Prompt time is directly adjusted at controller panel, and obtaining preferable heat seal effect with the shortest time during adjustment is foundation.After having been arranged, this function guaranteed that promptly product high-quality, production high efficiency make the best of both worlds, and reduced operator's labour intensity.
Bag Making Machine all adopts manual cutting mode at present, by stirring the cutter that blade is housed poly-bag is made in the bag making film cut-out.Because it is the most convenient and swift that operating process is once dialled left, dialled to the right, so cutter must be equipped with two blades next time.
Empirical evidence, it is parallel with angle and lower end that the installation of two blades needs certain position, any phenomenon that stops mutually must not be arranged, otherwise can not get desirable result of use.Present cutter structure must be installed by user (user) purchase double-edged razor blade (usefulness shaves) voluntarily, because the user differs to the understanding of installation requirement, consciousness to setting accuracy is also different, and the blade that they install is not ideal mostly, and result of use is also undesirable.
The utility model adopts be a kind of with two blades by the integrated bidirectional blade 7 of optimum position fixed angle on a sheetmetal, as Fig. 9, it has quick and easy for installation, the characteristics that result of use is good.
The utility model Bag Making Machine also is provided with spherical guide structure cuts device 11, and cutter 11 is arranged on movable casting die 2 can fix the slide construction that blade about 7 is stirred, and is the indispensable block construction of Bag Making Machine.Present cutter adopts ball bearing of main shaft, and its bearing only plays pulley action.Because L section bar 2 does not have guide rail, stir the skew of process (cutting process) cutter front and back, make the film otch all bad phenomenon occur.
The utility model adopts a kind of spherical guide structure cuts device.Its spherical guide structure is very accurate, and the diastema before and after no matter reaching up and down is all few, and it is very suitable to utilize its good structural behaviour characteristic to make the guide rail and the cutter of this machine.As Fig. 6, outer guide 112,114 is fixed on the L section bar 2 in the whole piece, the centre is provided with ball 111, cutter 11 partly is equipped with metal bin 115, operating handle 113 is stirred effective, in whole cut coverage, cutter 11 remains straight-line motion, without any skew, make the otch of film very straight.
It is elongated to understand deliquescing during general heating silk heating power, make heating wire keep straight, and two ends must be strained with extension spring.The heating wire chest expander of this kind machine is the steel strand exerciser of a simple structure at present, and its performance is not so good.
As Fig. 7~shown in Figure 8, the utility model then adopts a kind of guide rail structure heating wire chest expander, its structure is perfect, accurate, heating wire there is positioning action, pulling force is adjustable, and the heating wire two ends directly are fixed on the metal tongue bars 46, to not needing heat-producing two ends direct thermolysis is arranged, fix by extension spring 41, spacer 42, governing screw 43, check screw 44, nut pulling, spacer 42 can slide on guide rail 45.
Present similar machine does not have equalizer bar.Machine when not stepping on pedal frame, movable casting die 2 and fixing 3 opening-like attitudes of palpus of casting die.Because (effect of adjusting cross bar is to cooperate the length of adjusting main tie for movable casting die 2, adjustment cross bar, make the control position of movable casting die 2 just right), the self gravitation of transmission device and pedal frame etc. is very heavy, need reset tension spring to have corresponding pulling force, the extension spring of so big pulling force is very blunt, therefore want it to have enough Fu Ruliang, otherwise reseting procedure is dumb, and not in place or speed waits slowly.The richness of this pulling force is very important as measuring, it has increased labour intensity to the operator.
Shown in Figure 10-11, the utility model has designed an equalizer bar, and it is a lever principle structure of utilizing the relevant mechanical parts self gravitation of gravitational equilibrium, by the section bar manufacturing; As Figure 11, the one end links with adjusting cross bar 1-1, the other end is gravity end 10-2, the gravity end is a hollow section bar 10-2, be placed with an amount of weights such as iron during manufacturing within it, about 1/3rd places at the past gravity end of cross bar union end are provided with locating point 10-1, and when gravity end 10-2 equated with the mechanical parts own wt, the slight pulling force of 64 need of used reset tension spring got final product other complete machine reliable reset.So just, reduced operator's labour intensity.In addition, owing to move simultaneously at the action drive activity casting die two ends of equalizer bar 10.Therefore, as long as whole equalizer bar has enough mechanical strengths, press down (two ends put in place simultaneously when movable casting die pressed down) for the balance of movable casting die and play a role.
