The specific embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Embodiment based in the utility model, those of ordinary skills are not making all other embodiment that obtain under creative work prerequisite, all belong to the scope of the utility model protection.
As shown in Figure 1, Figure 2 and Fig. 3, what the utility model embodiment provided a kind of bag-feeding type package machine opens zippered bag mechanism, it comprises a framework 1, two drive-connecting shafts 11 are relatively set on described framework 1, pivot joint one first control piece 2 and one second control piece 3 on drive-connecting shaft 11 described in each, the end of described the first control piece 2 has one first contact part 23, and the end of described the second control piece 3 has one second contact part 33, and described the second contact part 33 is positioned at described the first contact part 23 outsides.
Between two relatively described the first control pieces 2, one first pushing block 4 is set, described the first pushing block 4 is wedge shape, and its underpart is slightly less than top, and described the first pushing block 4 is promoted and can be moved up and down by one first cylinder 41.Described the first control piece 2 has one first articulated section 21 that is articulated in described drive-connecting shaft 11, being convenient to described the first control piece 2 rotates around described drive-connecting shaft 11, described the first articulated section 21 is oblique to be descended and one first rake 22 that extends internally, described the first pushing block 4 be arranged at two described in the first rake 22 inner sides, being convenient to described the first rake 22 fully contacts with the left and right side of described the first pushing block 4, described the first contact part 23 extends to form downwards from described the first rake 22, described the first contact part 23 is in order to the one side of butt sack, the outside of described the first contact part 23 has a plurality of the first small embossments, one first extension spring 24 is set between the first rake 22 described in two, a restoring force is provided to the first control piece 2, allow the first control piece 2 get back to initial position.
One turning wheel 36 is set on the second control piece 3 described in each, described turning wheel 36 is positioned at the rear side of described the second control piece 3, one second pushing block 5 is set between turning wheel 36 described in two, the bottom of described the second pushing block 5 is slightly less than the distance between top, the left and right end of described the second pushing block 5 be connected to two respectively described in turning wheel 36, described the second pushing block 5 is promoted and can be moved up and down by one second cylinder 51.Described the second control piece 3 has one second articulated section 31 that is articulated in described drive-connecting shaft 11, being convenient to described the second control piece 3 rotates around described drive-connecting shaft 11, described the second articulated section 31 is oblique to be descended and one second rake 32 that extends internally, described turning wheel 36 is arranged at the top of described the second rake 32, described the second contact part 33 extends to form downwards from described the second rake 32, the inner side of described the second contact part 33 has a plurality of the second small embossments, being convenient to described the second small embossment and described the first small embossment cooperatively interacts and clamps a side of sack, prevent that sack from coming off, the second rake 32 a junction 34 that stretches out described in each, described connecting portion 34 is from the external formation that extends back in the lateral of described the second rake 32, one second extension spring 35 is set between connecting portion 34 described in two, an inside larger tightening force is provided to the second control piece 3.
Arranged outside one suction means 6 of described the second contact part 33, described suction means 6 has four suction nozzles 61, described in each, the outside of the second contact part 33 has two described suction nozzles 61, because sack has two faces that are oppositely arranged, is convenient to four suction nozzles 61 and holds respectively this two faces.
