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. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.

Referring to fig. 1-3, an automatic opening machine for plastic packaging bags comprises a pair of negative pressure clamping blocks 1, wherein the structure of each negative pressure clamping block 1 is consistent with that of a clamping block in the prior art, the negative pressure clamping block is hollow, an air suction device (not shown in the figure) is connected with the outside through a tracheal tube so as to form negative pressure suction force and facilitate sucking of a packaging bag opening, and meanwhile, the negative pressure clamping blocks 1 can be driven by a hydraulic rod to stretch and retract so that the two negative pressure clamping blocks 1 are close to or far away from each other so as to clamp the packaging bag when the two negative pressure clamping blocks 1 are close to each other and then far away from each other so as to open the packaging bag opening;

adjust the structure including with negative pressure clamp splice 1 fixed connection's support 3, rotate the lead screw 4 of installing between support 3 and negative pressure clamp splice 1, connect the servo motor 5 at support 3 top, the threaded bush is at nut 6 in the lead screw 4 outside and fix the electric putter 7 at nut 6 outer wall, wherein, servo motor 5's output shaft and lead screw 4 coaxial coupling, so that it is rotatory to drive lead screw 4, electric putter 7's output and splint 2 fixed connection, so that it is close to or keeps away from negative pressure clamp splice 1 to drive splint 2, and then can clip or loosen the wrapping bag mouth, and electric putter 7's axial lead and lead screw 4's axial lead mutually perpendicular.

Further, splint 2 adopts the convex fan-shaped structure of narrow width down for splint 2 expands wrapping bag mouth size when cliping the wrapping bag sack inboard, because splint 2 is the arc structure, makes can play certain water conservancy diversion effect when filling, reduces the problem that the material spills outward.

Further, in order to further improve the firmness that the clamping bag mouth is clamped by the clamping plate 2 and the negative pressure clamping block 1, the outer surface of the lower end of the clamping plate 2 is connected with an anti-skidding spacer 21, and the slipping condition is reduced.

Furthermore, in order to reduce the damage to the mouth of the packaging bag, the material of the anti-slip spacer 21 is made of one of elastic silica gel or elastic rubber, and the anti-slip spacer 21 has certain elasticity, so that when the anti-slip spacer 21 contacts the mouth of the packaging bag, the anti-slip resistance is ensured, the friction to the mouth of the packaging bag is reduced, and the protection effect on the mouth of the packaging bag is achieved.

Further, in order to guarantee the stability of the nut 6 in the lifting process, the sliding groove 31 is formed in the inner surface of the support 3, the sliding block 61 is fixed on one side, close to the sliding groove 31, of the nut 6, the sliding block 61 can stretch into the sliding groove 31 to slide, the sliding effect is utilized, the nut 6 is limited, and the nut 6 is prevented from axially deflecting.

Further, considering that the sliding friction resistance is large when the slider 61 slides in the slide groove 31, the rotatable ball 611 is embedded in the slider 61, the ball 611 is tightly attached to the inner wall of the slide groove 31, and the sliding friction resistance is reduced by the rotation of the ball 611, so that the nut 6 is smoother when moving up and down.

The working principle is as follows: during the use, at first negative pressure clamp splice 1 is cliied and is adsorbed wrapping bag mouth both sides, then start the hydraulic stem and drive negative pressure clamp splice 1 and keep away from each other, make negative pressure clamp splice 1 strut the wrapping bag sack, then start servo motor 5, servo motor 5 drives the relative support 3 rotation of lead screw 4, nut 6 drives splint 2 height that descends through electric putter 7, make splint 2 insert the wrapping bag inboardly, then start electric putter 7, electric putter 7 drives splint 2 and contracts, make splint 2 clip the wrapping bag sack with negative pressure clamp splice 1, the improvement is to the fastness that the wrapping bag sack struts.

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.
