Abstract
The utility model discloses a punching device of a plastic bag opening punching machine. The punching device comprises a frame, a pneumatic cylinder, a guide rod, a chopping block, a punching knife and a punching knife balance regulating device, wherein the punching knife balance regulating device consists of a regulating plate, a punching knife base plate, an elastic connecting mechanism and four regulating screws, and the elastic connecting mechanism consists of a sliding rod, a spring and a spring base. Elastic connection is formed between the regulating plate and the stamping knife base plate by the elastic connecting mechanism. The four regulating screws are arranged on the regulating plate. The contact angle of the punching knife and the chopping block can be changed as long as the regulating screw in a certain direction is tightened or loosened, and the punching gravity center is accordingly regulated. The punching device has the advantages of simple structure, high stability and reliability and convenience in regulation.
Description
Technical field
The utility model relates to a kind of polybag process equipment.
Background technology
The portable polybag (being convenient bag) that generally uses in people's daily life is all processed by tubular plastic film, earlier by Bag Making Machine the plastic foil two ends are added thermosetting twice involution line, cut out the rectangle plastics film section that is cut into a section again, automatically pile up into one pile after the rectangle plastics film section that all seal mouthful at the two ends of the every output some of Bag Making Machine, and then die-cut through the machine of blurting out, cut into the portable polybag with handle shape at an end of plastic foil.The machine of blurting out in die-cut process, because stamping knife is " W " shape, discontinuity, and center of gravity also can change when changing the model of polybag, needs often to adjust.In addition blanking units in use for some time frame also can correspondingly be out of shape, need often to proofread and correct.Traditional control method is exactly to regulate in the method for cylinder block or stamping knife seat board increase and decrease pad.It is inaccurate, inconvenient to exist adjustment, problems such as job insecurity.
The utility model content
Technical problem to be solved in the utility model be exactly for the polybag machine of blurting out provide a kind of simple in structure, reliable and stable, adjust the blurt out blanking units of machine of polybag easily.
For solving the problems of the technologies described above, the technical solution of the utility model is: blurting out at polybag arranges one and adjusts plate between the cylinder of machine and the stamping knife seat board, the stamping knife seat board is connected by flexible connection mechanism elasticity and adjusts on the plate the following installation stamping knife of stamping knife seat board; Adjust and on the plate adjustment screw to be set respectively all around, adjust the angle that screw changes stamping knife and chopping block by twisting, the adjustment center of gravity.
As optimized technical scheme, cylinder is installed in centre position, described frame top, and the lower end of cylinder rod is installed and adjusted plate, around the adjustment plate flexible connection mechanism is installed respectively, and the inboard of four flexible connection mechanisms arranges four and adjusts screw.
As optimized technical scheme, described flexible connection mechanism is made of compression spring, spring base, slide bar, nut.The lower end of slide bar is installed on the stamping knife seat board, and the adjustment plate of slide bar correspondence is provided with open-work, and slide bar passes mounting spring seat behind the open-work of adjusting plate, compression spring, spring base, and the top of slide bar is provided with nut.Stamping knife be installed in the stamping knife seat board below.
Owing to adopted technique scheme, when tightening or unclamp the adjustment screw of a certain direction, can change the angle of stamping knife and chopping block, change die-cut center of gravity, can increase the weight of or alleviate the die-cut dynamics to this orientation of polybag effectively, adjust efficient and convenient.Because be that elasticity connects between stamping knife seat board and the adjustment plate, screw is difficult for loosening; Even slight deformation appears in frame in the die-cut process, flexible connection mechanism has automatic compensating action, owes slightly under the accurate situation in adjustment, also can play the effect of self adaptation and self-balancing pressure.The present invention is simple in structure, and is practical, reliable and stable.
Description of drawings
Fig. 1 is the structure principle chart of the utility model embodiment;
Fig. 2 is the structural principle vertical view of the utility model embodiment;
The specific embodiment
Further set forth the utility model below in conjunction with accompanying drawing 1, accompanying drawing 2.The blurt out blanking units of machine of polybag described in the present embodiment comprises frame 1, cylinder 3 is installed in the centre position, upper end of described frame, in the lower end of cylinder rod 11 adjustment plate 8 is installed, for limiting adjustment plate 8 and stamping knife 10 with cylinder rod 11 rotations, in the position, the left and right sides of adjusting plate 8 guide rod 2 is installed respectively, be drilled with open-work respectively on four angles adjusting plate 8, four of the installed inside of four open-works are adjusted screw 12; Pass from four open-works adjusting plate 8 in that 7, four slide bars of slide bar are installed respectively on four angles of stamping knife seat board, pass on the slide bar 7 of part mounting spring seat 5, spring 6, spring base 5 respectively, nut 4 is installed in the top of slide bar, and spring 6 is compressed; Below the following installation stamping knife 10 of stamping knife seat board 9, the frame corresponding with stamping knife chopping block 13 is set.
The concrete adjustment process of concrete blanking units is as follows:
Do not get off or die-cut thoroughly the time if the front position of polybag is die-cut, adjust screw 12 for those two that just tighten the front, adjusting pressure that screw 12 can overcome spring faces down before with stamping knife seat 9 and backs down certain distance, changed the contact angle of stamping knife 10 with chopping block 13, the front of stamping knife is contacted earlier with polybag and chopping block earlier, so just can change die-cut center of gravity effectively; If two that just unclamp some fronts when cut to get off the back are adjusted screw, adjust screw for two that perhaps tighten the back; If top that an angle of polybag is die-cut just tightens this angle correspondence when not getting off adjusted screw, perhaps unclamp other three and adjust screws.
