Upright packing machine automatic clamp film device described in the utility model, can automatically clamp or unclamp packaging film, realizes Automatic change film function, simple, convenient, has improved the work efficiency of wrapping machine.
Accompanying drawing explanation
Fig. 1 is the structural representation of upright packing machine automatic clamp film device described in the utility model;
Fig. 2 is the local enlarged diagram of A shown in Fig. 1;
Fig. 3 is the planar structure schematic diagram of upright packing machine automatic clamp film device described in the utility model.
The specific embodiment
As shown in Figure 1 to Figure 3, upright packing machine automatic clamp film device described in the utility model comprises frame 10, screw mandrel 20, moving guide rail 30, the first shifting board 41, the second shifting board 42 and turbine and worm motor 50.Screw mandrel 20 and moving guide rail 30 are installed in parallel in respectively in frame 10, and turbine and worm motor 50 is arranged on the side of frame 10.Turbine and worm motor 50 is connected in one end of screw mandrel 20, for controlling screw mandrel 20, rotates forward or backwards.
The left end of screw mandrel 20 is provided with right-hand screw thread, and its right-hand member is provided with minus thread.The first shifting board 41 is threaded connection in the left end of screw mandrel 20, and is movably arranged on moving guide rail 30; The second shifting board 42 is threaded connection in the right-hand member of screw mandrel 20, and is movably arranged on moving guide rail 30.30 pairs of the first shifting boards 41 of moving guide rail, the second shifting board 42 fixing, directional taggings.The medial surface of the first shifting board 41 is provided with for clamping the medial surface of the first swivel block 43, the second shifting boards 42 of packaging film and is provided with for clamping the second swivel block 44 of packaging film.On the second shifting board 42, be also provided with back-up ring 45 and approach switch 46, back-up ring 45 is connected with the second swivel block 44 by spring, and approach switch 46 is positioned at the both sides of back-up ring 45 and is connected with turbine and worm motor 50 electricity.
The principle of work of upright packing machine automatic clamp film device described in the utility model is as follows:
When needs are installed packaging film, start turbine and worm motor 50, turbine and worm motor 50 drives screw mandrel 20 to make forward rotation, at the minus thread at screw mandrel 20 two ends, under the directional tagging of the effect of right-hand screw thread and moving guide rail 30, the first shifting board 41 and the second shifting board 42 move inward respectively, and drive the first swivel block 43 and the second swivel block 44 to move inward, thereby engage with the volume core of packaging film.After the first shifting board 41 and the second shifting board 42 clamp packaging film, the second swivel block 44 drives back-up rings 45 outwards to move, and triggers the approach switch 46 in outside, represents to have clamped packaging film, and approach switch 46 indicates turbine and worm motor 50 to stop operating.
When needs unload packaging film, start turbine and worm motor 50, turbine and worm motor 50 drives screw mandrel 20 to rotate backward, at the minus thread at screw mandrel 20 two ends, under the directional tagging of the effect of right-hand screw thread and moving guide rail 30, the first shifting board 41 and the second shifting board 42 are outwards mobile respectively, thereby separated with packaging film.Back-up ring 45 moves inward under the effect of spring, triggers the approach switch 46 of inner side, represents to have decontroled packaging film, and approach switch 46 indicates turbine and worm motor 50 to stop operating.
Upright packing machine automatic clamp film device described in the utility model, can automatically clamp or unclamp packaging film, realizes Automatic change film function, simple, convenient, has improved the work efficiency of wrapping machine.
The above embodiment has only expressed several embodiment of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
