210, negative pressure cavity 210 is provided only with two and connects extraneous mounting hole, and the left end sealing of transmission sleeve pipe 22 is inserted in the mounting hole, roller
Cylinder 21 is coaxially disposed with transmission sleeve pipe 22, and mounting hole is tightly connected with another for the inner of the suction nozzle 26, the outer end of suction nozzle 26
The outer peripheral face of the roller 21 is protruded from, and suction nozzle 26 is arranged at the close left end of roller 21.The fixing assembling of piston 25 is in this
The left end of pull bar 24, pull bar 24 is set in the transmission sleeve pipe 22, and the two ends of transmission sleeve pipe 22 are assemblied in above-mentioned machine by bearing
On frame 1.The left end of pull bar 24 is extended in the negative pressure cavity 210, and the right-hand member of transmission sleeve pipe 22 is provided with the spacing window axially extended
220, the inner of the mounting rod 30 is fixedly connected through the spacing ground of window 220 with the right-hand member of the pull bar 24, and the road wheel 29 is fixed
The outer end of the mounting rod 30 is assemblied in, the back-moving spring 27 is assemblied in the transmission sleeve pipe 22, and back-moving spring 27 is sheathed on above-mentioned
The right-hand member of pull bar 24, the right-hand member of back-moving spring 27 is abutted with the inwall of above-mentioned transmission sleeve pipe 22.Back-moving spring 27 is used to promote this
Pull bar 24 resets to the left.The fixing assembling of synchromesh gear 23 in the right-hand member of the transmission sleeve pipe 22, two pull open mechanism 2 synchronous gear
23 engaged transmissions are taken turns, the drive mechanism drives the synchromesh gear 23 to rotate.The interference bump 28 is aligned with road wheel 29 and set, should
Interference bump 28 be middle part to right flange structure, during transmission sleeve pipe 22 drives the fixed-axis rotation of road wheel 29, pass through interference
The interference of projection 28 promotes pull bar 24 to walk to the right, and two road wheels 29 for pulling open mechanism 2 are in synchronously along the interference bump 28
In up process, two correspondences of suction nozzle 26 for pulling open mechanism 2 hold the sack of packaging bag 3 and pull open sack.
With continued reference to Fig. 1, in addition, the above-mentioned mechanism 2 that pulls open can also configure orbit ring 31, orbit ring 31 is securely fitted in
State in frame 1.Above-mentioned interference 28 fixing assemblings of projection are on the side wall of the orbit ring 31, and above-mentioned road wheel 29 is along the side of orbit ring 31
Wallflow is walked.Above-mentioned interference projection 28 for both sides are low and round and smooth grading structure that middle part is high, the two ends of interference bump 28 and above-mentioned rail
The side wall rounding off of road ring 31.
With continued reference to Fig. 1, Fig. 2, in use, packaging bag 3 is passed through between two rollers 21, the direction of rotation figure of roller 21
