Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.
Referring to fig. 1-3, a packing device for polyethylene resin production comprises a mounting plate 4, wherein grabbing frame connecting grooves 16 are symmetrically distributed on the mounting plate 4, grabbing frames 11 are hinged inside the grabbing frame connecting grooves 16, connecting buckles 14 are fixedly mounted at the central positions of one sides of the outer walls of the two grabbing frames 11, hydraulic cylinders 5 are arranged at one sides of the outer walls of the grabbing frames 11, ejector rods 15 are fixedly mounted at the output ends of the hydraulic cylinders 5, the hydraulic cylinders 5 are located on the upper surface of the mounting plate 4, movable plates 20 are rotatably mounted at the lower ends of the grabbing frames 11 on the lower surface of the mounting plate 4, suckers 12 are slidably mounted on the movable plates 20 in an evenly distributed manner, a second expansion spring 13 is arranged on the outer wall of each sucker 12, one end of the second expansion spring 13 is fixedly connected with the outer wall of one side where the two grabbing frames 11 are close to each other, and the other end of the second expansion spring 13 is fixedly connected with the sucker 12, one side of the upper surface of the mounting plate 4 is provided with connecting rods 6 in a symmetrical distribution manner along the vertical direction, two connecting rods 6 are fixedly provided with supporting bottom plates 8 at the bottom ends, a limiting block 2 is fixedly provided at the top end of each connecting rod 6, the outer wall of each connecting rod 6 is provided with a first expansion spring 3, two first expansion springs 3 are fixedly connected at the bottom ends and the upper surface of the mounting plate 4, the top ends of the first expansion springs 3 are fixedly connected with the lower surface of the limiting block 2, a sliding groove 18 is formed at the other side of the upper surface of the mounting plate 4 in a symmetrical distribution manner, a supporting rod 19 is arranged in the sliding groove 18 along the vertical direction, a connecting frame 17 is fixedly arranged at the top ends of the two supporting rods 19, and the connecting frame 17 is fixedly connected with one ejector rod, the intermediate position and two of connecting rod 6 the equal fixed mounting in bottom of bracing piece 19 has fixed wainscot 7, the central point of mounting panel 4 puts fixed mounting and has feed inlet 1, two the upper and lower both ends of fixed wainscot 7 all are provided with the fillet, and fixed wainscot 7 is circular-arc, every the equal fixedly connected with trachea of one end of sucking disc 12.
The working principle is as follows: in the using process of the device, firstly, the hydraulic cylinders 5 are started, the mandrils 15 at the output ends of the two hydraulic cylinders 5 push the two grabbing frames 11 to move oppositely or repulsively, in the opposite movement, the lower ends of the two grabbing frames 11 are far away from each other, so that the separation effect is realized, in the repulsing movement, the lower ends of the two grabbing frames 11 are close to each other, so that the compaction effect is realized, because the lower ends of the grabbing frames 11 are rotatably provided with the movable plates, and each movable plate 20 is provided with the sucking disc 12, in the compaction process, the second expansion spring 13 arranged on the outer wall of the sucking disc 12 can reduce the impact force in the movement of the grabbing frames 11, so that the service life of the sucking disc 12 is prolonged, then the sucking disc 12 is attached to the packaging bag, and then the air in the contact area of the sucking disc 12 and the packaging bag is extracted through the air pipe on, produce enough big pressure differential, make sucking disc 12 can be stable adsorb the wrapping bag, thereby have good stability, then, pneumatic cylinder 5 restarts, make even one snatch frame 11 and do the motion in opposite directions, make fly leaf 20 separation of lower extreme, thereby open the department of sealing of wrapping bag, and pour into the resin into to the wrapping bag inside through feed inlet 1, the bottom of wrapping bag is located supporting baseplate 8, and the pneumatic cylinder 5 that is close to bracing piece 19 can pass through link 17, can control bracing piece 19 simultaneously and drive the fixed wainscot 7 of its lower extreme and slowly move to the fixed wainscot 7 department of opposite side, can play the effect of stabilizing the wrapping bag, along with the weight of the inside resin of wrapping bag increases gradually, closer 10 on one of them stopper 2, slowly contact with touch switch 9, then signal, feed inlet 1 stops annotating the material.
After the material filling and packaging operation is finished, the hydraulic cylinder 5 controls the two grabbing frames 11 to move in a repelling manner again, so that the suckers 20 on the two movable plates 20 are pressed to seal the opening, and the fixed waist plate 7 on one side is fixed at the middle part of the packaging bag.
The above, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, the concept of which is equivalent to replace or change, should be covered within the protection scope of the present invention.
