Detailed Description

The present invention will be described in detail with reference to the drawings, and it should be understood that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

As shown in fig. 1 and 2, the utility model provides a mechanical gripper device, which is particularly suitable for gripping and lifting the special mechanical gripper of woven bags. Because the braided bag is after being equipped with the heavy object, the quality descends, and the last border position of knitting is little, and the braided bag both ends all have the hem seam limit to seal, and the width on hem seam limit is generally about 3-5cm, is difficult for promptly for the difficulty increases at whole in-process of snatching, for this reason, the utility model relates to a new tongs can grab the braided bag fast. The utility model discloses a mechanism 1 that snatchs that can open and shut, the tip of snatching mechanism 1 is installed the structure the same and is gone up tongs 2 and time tongs 3, it includes that last fixed roll 21 and last sawtooth grab 22 to go up tongs 2, tongs 3 includes down fixed roll 31 and lower sawtooth grab 32 down, it grabs 22 and lower sawtooth grab 32 cooperation that opens and shuts to go up the sawtooth, snatchs article.

Further, install drive arrangement on the mechanism 1 that snatchs that can open and shut, the utility model discloses in drive arrangement is piston cylinder 5, in addition, also can be other power provides the device, can help carrying out power and open and shut, and is exemplary, can be the hydro-cylinder also can be the cylinder device.

Specifically, the utility model discloses in, snatch mechanism 1 includes first connecting bolt round pin 4, install lever 41 and lower lever 42 on the first connecting bolt round pin 4, go up tongs 2 and install perpendicularly in the tip of last lever 41, lower tongs 3 installs perpendicularly in the tip of lower lever 42.

The upper fixing roller 21 and the upper saw-tooth grab 22 are connected through an upper support arm connecting bolt 23; the lower fixed roller 31 and the lower serrated jaw 32 are connected by a lower support arm connecting pin 33. The upper fixing roller 21 and the upper saw-tooth grab 22 are respectively provided with a first support arm 6, and the first support arm 6 is arranged on an upper support arm connecting bolt 23; the lower fixing roller 31 and the lower serrated jaw 32 are respectively provided with a second supporting arm 7, and the second supporting arm 7 is mounted on a lower supporting arm connecting bolt 33.

In addition, go up the fixed roll 21 and install the infrared inductor 8 that is used for apart from the response on the fixed roll 31 down. The grabbing mechanism 1 is provided with a counter, and the number of grabbing can be counted.

The utility model discloses a working process does:

the power drive of the whole gripper is provided by a piston cylinder 5 on the upper lever, the tail ends of the upper and lower levers 41 and 42 penetrate through the same rotating shaft and are connected through a first connecting bolt pin 4, the two levers rotate up and down around the rotating shaft to realize the opening and closing of the lever ends, the lever ends are respectively and vertically welded with a supporting arm inwards, the ends of the supporting arms are connected with the gripper which is not more than the width of a seam edge along the lever direction through movable bolt pins, the front end of the gripper is provided with an upper sawtooth gripper 22 and a lower sawtooth gripper 32, and the rear end of the gripper is provided with a cylindrical upper fixed roller 21 and a cylindrical lower fixed roller 31. When the lever is driven by the driving cylinder to close, because the upper and lower saw- tooth grippers 22, 32 and the upper and lower fixed rollers 21, 31 are different from the distance of the connecting bolt of the supporting arm, the upper and lower fixed rollers 21, 31 are closed to fix the sealed edge, then the upper and lower saw- tooth grippers 22, 32 are closed, the folded edge is engaged and gripped by the upper and lower saw- tooth grippers 22, 32, the system is provided with an infrared sensor 8 between the upper and lower fixed rollers 21, 31, once a bag is detected to enter between the upper and lower fixed rollers, the driving cylinder starts to drive the fixed rollers and the saw-tooth grippers to close successively, as shown in figure 3, the bag is successfully gripped, the gripping movement is achieved, the driving cylinder is driven to move upwards to release the lever and the saw-tooth grippers to open sequentially, the process is to ensure that the fixed rollers are in a closed state when the saw-tooth grippers are loosened, and the purpose that the saw-tooth grippers are completely disengaged from the woven bag is achieved, completing one-time circular grabbing. The system can also be provided with counting equipment to achieve the purpose of counting the number of the objects.

Further preferably, the utility model discloses a ensure that the fixed roll is preferred closed, install the spring of a deviation to the fixed roll direction on connecting bolt 23, 33, can guarantee at any time that the angle that opens and shuts of first support arm 6 and second support arm 7 is the outer eight characters shape of the distance that opens and shuts of fixed roll is less than that the sawtooth is grabbed all the time under the spring action of this spring to this reaches the preferred closed preferred mesh of loosening of fixed roll, makes and snatchs more accurate.

It should be apparent to those skilled in the art that the above embodiments are only preferred embodiments of the present invention, and therefore, the modifications and changes that can be made by those skilled in the art to some parts of the present invention still embody the principles of the present invention, and the objects of the present invention are achieved, all falling within the scope of the present invention.
