Description
Technical field
The utility model relates to mechanical equipment technical field, particularly relates to Bag Making Machine.
Background technology
Bag Making Machine is the specialized equipment making packaging bag, is widely used in the production of the packaging bag of the materials such as various plastics, papery.Traditional high-speed bag making machine is plastic multiple packaging bag once, its manufacturing process is: conveying of upper film and lower film being led respectively, in correct position, overlap is carried out to upper and lower film, film after overlap forms multiple pouch integrative-structure after longitudinal direction, transversal heat seal, finally cuts pouch and forms multiple pouch.Unwinding device is launched into plane for rolling tubular film, convenient heat-sealing, one-tenth bag.The reel of existing unwinding device is freely placed on spool, front end trailer coupling tracting film is relied on to unreel, when its shortcoming is trailer coupling tracting film, the distortion of film is larger, when reel freely unreels, inertia causes more greatly film easily to extrude overlap together, film easily wanders off, particularly for the conveying of discontinuous film, this unwinding device is more not suitable for.
Utility model content
The applicant, for the above-mentioned shortcoming of existing Bag Making Machine, carries out studying and improving, and provides that a kind of structure is simple, reliable operation, unwinding device with the Bag Making Machine of self-driven self-retention function.
The technical scheme that the utility model adopts is as follows:
A unwinding device for Bag Making Machine, this device comprises the spool of wheel word between two frame plates, and there is brake equipment at the two ends of described spool respectively device, and one end band has actuating device;
Described actuating device comprises the spool drive wheel affixed with spool, and spool drive wheel is connected by meshing transmission by power wheel and motor driving wheel, and motor driving wheel is driven by the motor be fixed on frame plate;
Described brake equipment comprises brake cylinder, cylinder ends and the mounting bracket of brake cylinder are hinged, the affixed U-shaped grip block in end of its piston rod, one end of described U-shaped grip block and slipper is hinged, the middle part of slipper is articulated with on cross bar, described mounting bracket and cross bar are fixedly connected with frame plate respectively, and described slipper is around its rotating middle part under the promotion of brake cylinder, and the wheel hub of its other end and spool drive wheel touches.
Further improvement as technique scheme:
Described electric machine is in the madial wall of described frame plate; The two ends of described slipper are respectively with curved hook portion.
The beneficial effects of the utility model are as follows:
Structure of the present utility model is simple, adopts motor to drive film roll to unreel, reduces the tractive force of follow-up draw gear, thus reduce film tension force, reduce its distortion; Arranging brake equipment avoids the inertia of film roll to unreel, and improves the reliability unreeled, and can regulate the speed of unreeling, and keeps unreeling the tension force of film in process and is in OK range.

Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described.
As shown in Figures 1 to 6, the unwinding device of the Bag Making Machine of the present embodiment, this device comprises the spool 2 of wheel word between two frame plates 1, device film roll (not shown) on spool 2, there is brake equipment 4 at the two ends of spool 2 respectively device, and one end band has actuating device 3;
Actuating device 3 comprises the spool drive wheel 31 affixed with spool 2, spool drive wheel 31 is connected by meshing transmission by power wheel 32 and motor driving wheel 33, motor driving wheel 33 is driven by the motor 34 be fixed on frame plate 1, and motor 34 concealed device is in the madial wall of frame plate 1; Motor 34 drives spool 2 to rotate by motor driving wheel 33, power wheel 32 and spool drive wheel 31, thus drives film roll rotation to unreel, and to reduce the tractive force of follow-up draw gear, reduces deformation of thin membrane;
Brake equipment 4 comprises brake cylinder 42, cylinder ends and the mounting bracket 45 of brake cylinder 42 are hinged, the affixed U-shaped grip block 44 in end of its piston rod, U-shaped grip block 44 is hinged with one end of slipper 43, the middle part of slipper 43 is articulated with on cross bar 41, mounting bracket 45 and cross bar 41 are fixedly connected with frame plate 1 respectively, slipper 43 under the promotion of brake cylinder 42 around its rotating middle part, the wheel hub 35 of its other end and spool drive wheel 31 touches, realize braking function, avoid the inertial rotation of film roll, improve and unreel reliability; For reducing the stroke of brake cylinder 42, the two ends of slipper 43 are respectively with the curved hook portion bending towards the same side.
More than describing is to explanation of the present utility model, and be not the restriction to utility model, the utility model limited range is see claim, and when without prejudice to spirit of the present utility model, the utility model can do any type of amendment.
