The object of packing machine is collected lifting mechanism
Technical field:
The utility model relates to a kind of packing machine, and the object that is specifically related to a kind of packing machine is collected lifting mechanism.Belong to the packaging facilities technical field.
Background technology:
Before utility model was made, the object of traditional packing machine was collected lifting mechanism and is collected object by cylinder drive windrow platform upward movement, and moving velocity is slow, and collection efficiency is low.And.Be difficult to control with the cylinder action.
Summary of the invention:
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of motion control easily is provided, and the object of the packing machine that collection efficiency is high is collected lifting mechanism.
The purpose of this utility model is achieved in that a kind of object collection lifting mechanism of packing machine, it is characterized in that it comprises: turn-screw, nut, slide block, chute, four-bar linkage, windrow platform, guide pin bushing, guide pillar and frame, described nut and slide block respectively have two, forward and backward each one, described chute and four-bar linkage respectively have two, left and right each one, guide pin bushing and guide pillar respectively have two, and described two chute one left sides, right sides are arranged at the frame two bottom sides; Turn-screw is arranged in the middle of the frame bottom, be shaped on minus thread and right-hand screw thread on the turn-screw respectively, described two forward and backward spiral shells of nut are located on the turn-screw, link to each other with two nuts respectively in the middle of described two slide blocks, and left and right two ends place respectively in left and right two chutes; The two ends of described left and right two four-bar linkages link to each other with the left and right two ends of forward and backward two slide blocks respectively, middle hinge-point links to each other with windrow platform and arranged on left and right sides, and the windrow platform links to each other with guide pin bushing, and guide pin bushing is placed on the guide pillar, forward and backward each one of guide pillar is installed in the middle of the frame.
The object of the utility model packing machine is collected lifting mechanism, and described turn-screw links to each other with power wheel, and power wheel links to each other with servomotor.
Servomotor work drives turn-screw and rotates, and the nut on the leading screw is forward and backward oppositely to be moved, and drives slide block and oppositely moves in left and right chute group, to realize the lifting of four-bar linkage, moves downward thereby drive the sliding guide pillar of windrow platform.
Compare with technology is arranged, the utlity model has following advantage:
1, the windrow platform moves downward and collects object, and moving velocity is fast, the collection efficiency height.
2, adopt servomotor control, the accuracy of positioning height that the windrow platform is every layer, control method is simple.
Description of drawings:
Fig. 1 is a perspective view of the present utility model.
Fig. 2 is the A-A cutaway view of Fig. 1.
Fig. 3 is the lateral plan of Fig. 1.
The specific embodiment:
Referring to Fig. 1~3, the utility model is a kind of collection lifting mechanism.Mainly form by servomotor 1, power wheel 2, turn-screw 3, nut 4, slide block 5, chute 6, four-bar linkage 7, windrow platform 8, guide pin bushing 9, guide pillar 10 and frame 11.
Described nut 4 and slide block 5 respectively have two, forward and backward each one.Described chute 6 and four-bar linkage 7 respectively have two, left and right each one.Described guide pin bushing 9 and guide pillar 10 respectively have two.
Described left and right two chutes 6 are arranged at frame 11 bottom and arranged on left and right sides.Turn-screw 3 is arranged in the middle of frame 11 bottoms.Link to each other with power wheel 2 in the middle of the turn-screw 3, power wheel 2 links to each other with servomotor 1.
Described two nuts, 4 forward and backward spiral shells are located on the turn-screw 3, are shaped on minus thread and right-hand screw thread on the turn-screw respectively.Link to each other with forward and backward two nuts 4 respectively in the middle of two slide blocks 5, left and right two ends place respectively in the left and right chute 6.Left and right four-bar linkage 7 two ends link to each other with the left and right two ends of forward and backward slide block 5 respectively, and middle hinge-point links to each other with windrow platform 8 and arranged on left and right sides are middle.The windrow platform links to each other with two guide pin bushings 9 respectively in the middle of the 8 forward and backward both sides.Two guide pin bushings 9 are placed on respectively on two guide pillars 10.Two forward and backward each parts of guide pillar are installed in the middle of the frame 11.
Among Fig. 1: ground floor object 12, second layer object 13 and the 3rd layer of object 14.
