Mechanism includes institutional framework 1, and the front end of frame is the bag pushing board 101 in face of packaging bag, and bag pushing board 101 is straight when grabbing packaging bag
To being pressed in packaging bag, at least one set of handgrip hole is set, there are two one group of handgrip holes, respectively upper handgrip hole 102 in bag pushing board
With lower handgrip hole 103, two handgrip holes are oppositely arranged up and down, are corresponded to handgrip hole in the frame and are provided with handgrip, the handgrip point
For two upper handgrips 2 and a lower handgrip 3, a lower handgrip is between two upper handgrips or under the handgrip is divided into two
The upper handgrip 2 of handgrip 3 and one, a upper handgrip between two lower handgrips, as shown in figure 3, the upper handgrip and lower handgrip by
Arc-shaped pawl refers to 201,301 and the composition of linear type gripping arm 202,302, as depicted in figs. 1 and 2, a driving device driving is grabbed
The finger tip that armband pawl refers to stretches out the outside for being close in bag pushing board 101 from upper and lower two handgrip holes respectively, or expansion is retracted in
The inside of bag pushing board 101, a shaft 4 refer to that the circular hole 203,303 being arranged gripping arm will across upper handgrip and lower handgrip pawl
Upper handgrip and lower handgrip rotational positioning, shaft 4 are fixedly connected with institutional framework 1, the pawl finger tip of the upper handgrip and lower handgrip
After stretching is closed up in upper and lower two handgrip holes, shown in the enlarged drawing of local A as shown in figure 1,204 He of pawl finger tip of upper handgrip
The pawl finger tip 304 of lower handgrip is interlaced to surmount intersection, and as shown in the enlarged drawing of the local B of Fig. 2, the tip of the finger tip is arrived
Pawl refers to that inner arc surface is one section of straight line plane 205,305, and linear distance length is in 5mm to 10mm, one section of straight line plane and gripping arm
The angle a of central axis is greater than 100 degree, and angle a is most preferably between 100 degree to 130 degree, and the present embodiment is at 115 degree.
The driving device in embodiment includes a pneumatic cylinder or hydraulic cylinder 5, and pneumatic cylinder or hydraulic cylinder 5 are fixed on
In frame, the telescopic arm of pneumatic cylinder or hydraulic cylinder connects a push arm 6, and push arm is rotatablely connected one group of linking arm by connecting shaft 7
One end, one group of linking arm is upper handgrip linking arm 8 and lower 9 two linking arms of handgrip linking arm, two linking arm other ends point
It is not connect with the gripping arm of upper handgrip and the gripping arm of lower handgrip by the hinge of hinge axis 10 and 11, two linking arms and upper handgrip are grabbed
The gripping arm length of arm and lower handgrip unanimously constitutes mutual hinged parallelogram lever, the linear expansion of telescopic arm
Push and pull two linking arms, two linking arms realize finger tip that pawl refers to respectively from upper and lower two handgrips by parallelogram lever
It is stretched out in hole and closes up or be unfolded to withdraw.
It is reliable in order to grab, multiple handgrips can be set, it may be assumed that being horizontally spaced about in the bag pushing board has multiple groups handgrip
Hole, such as 3 shown in fig. 6, or it is more.The setting of multiple groups handgrip hole horizontal interval, corresponds to each group of handgrip hole in the frame
It is respectively arranged with handgrip, when the handgrip hole is two groups, corresponding two handgrips in two groups of handgrip holes are separately connected one group of connection
Arm, and two handgrips are all two upper handgrips 2 and a lower handgrip 3, and a lower handgrip is between two upper handgrips, Huo Zhesuo
It states handgrip and is divided into two lower handgrips 3 and a upper handgrip 2, a upper handgrip is between two lower handgrips.
Wherein: when the handgrip hole is three groups, the gripping arm other end of the upper handgrip of handgrip corresponding to intermediate handgrip hole
It is connected to the gripping arm other end of lower handgrip on the hinge axis of the gripping arm of adjacent upper handgrip and the gripping arm other end of lower handgrip.
And: when the handgrip hole is three groups, the handgrip corresponding to the intermediate handgrip hole is under two upper handgrips and one
When handgrip, then handgrip corresponding to both sides handgrip hole is two lower handgrips and a upper handgrip；Alternatively, as shown in Figure 7, in the middle
Between handgrip corresponding to handgrip hole be two lower handgrips and a upper handgrip, then handgrip corresponding to both sides handgrip hole is on two
Handgrip and a lower handgrip.
To packaging bag not with damage when in order not to make to pick up, as shown in figure 4, adjustment driving device makes the upper handgrip under
When bag pushing board handgrip hole to crawl packaging bag is stretched out in handgrip expansion, described one section of plane of upper handgrip finger tip and one section of handgrip finger tip lower
The angle C of the intersection of 205 305 extended line of straight line plane, intersection is not more than 10 degree.
The handgrip fingertip end of handgrip is designed to 205 line segment of straight line plane with the angle of gripping arm central axis by embodiment.
For handgrip finger tip when around fixing axle rotation, finger tip first penetrates material bag arm in this way, is then referred to material bag push-in pawl with straight flange
Circular arc in, when two pawl finger tips interlock after by two pawls refer to direct material bag arm section with the form encircled enter up and down two
Pawl refers in the gap directly formed, also, the angle of the straight line planar section at the pawl finger tip of handgrip and gripping arm central axis: when
Two stringcourses of two straightways can intersect after extending to the left when two groups of handgrips are opened.When handgrip closure, the angle of two straightways prolongs
Long line cannot intersect after extending.Handgrip not will form when encircling material bag bag wall and cut out power in this way.In this way to material bag bag arm
Form protection well.
The present embodiment is grabbed bag mechanism and is mounted on lever arm, it can uses as a bag arm is grabbed, can also be used as sack
Opening arm uses.
