Brief description of the drawings
Fig. 1 and Fig. 2 are three-dimensional structure diagram of the present invention.
Fig. 3 is front view of the present invention.
In figure: 1, the first push rod; 2, the second push rod; 3, set square; 4, cross bar; 5, the first connecting plate; 6, catch bar; 7, promote connecting plate; 8, assistant cylinder; 9, bearing; 91, side plate; 92, mounting blocks; 10, magnetic switch; 11, roller.
Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.
As shown in Figure 1 to Figure 3, the upper cutter thrust unit of the Bag Making Machine of the present embodiment, comprises the catch bar 6 being hinged and promotes connecting plate 7, catch bar 6 is driven by promotion source; Drive source can, for pushing cylinder, push air cylinder driven catch bar 6 and move reciprocatingly; Drive source also can comprise drive motors, and the motor shaft of drive motors connects cam or the eccentric wheel hinged with catch bar 6, and drive motors band moving cam or eccentric wheel rotate and make equally catch bar 6 move reciprocatingly; Drive source is not limited to above-mentioned two kinds, can also can make the reciprocating device of catch bar 6 for other.
Promote connecting plate 7 hinged with the lower end of push rod, the upper end of push rod connects upper cutter frame and (does not draw, see the patent of application on the same day: the upper cutter device of Bag Making Machine), push rod comprises first push rod 1 and second push rod 2 of symmetrical vertically-oriented carriage on upper cutter frame, the hinged set square 3 in lower end of the first push rod 1, hinged first connecting plate 5 in lower end of the second push rod 2, is fixedly connected with cross bar 4 between set square 3 and the first connecting plate 5, and cross bar 4 is affixed with promotion connecting plate 7;
This device also comprises assistant cylinder 8, and on the cylinder body of assistant cylinder 8, device has magnetic switch 10, and magnetic switch 10 is for controlling the piston rod movement stroke of assistant cylinder 8; The cylinder body of assistant cylinder 8 is articulated with in frame by bearing 9, and the end of its piston rod and set square 3 are hinged.Bearing 9 comprises the side plate affixed with frame 91 and the mounting blocks 92 hinged with the cylinder body of assistant cylinder 8, side plate 91 vertical be connected relative to mounting blocks 92.
For preventing from action interference, promote connecting plate 7 being positioned at the inner side of set square 3, assistant cylinder 8 is positioned at the outside of set square 3; The end of cross bar 4 is fixed in the base of set square 3, and the lower end of the first push rod 1 is articulated with drift angle place relative with base on set square 3.
