Description
Technical field
The utility model belongs to packaging facilities field, and what particularly relate to a kind of volume film send film placing mechanism.
Background technology
Volume film described in the utility model is put film device and can be used for actions such as the film and stopping of veering away of volume film stop.The film placing mechanism that send of volume film generally comprises volume film supporting component, brake assemblies and puts the compositions such as film signal swing arm.Wherein roll up film supporting component to be made up of air-expanding shaft assembly, bearing block assembly and air-expanding shaft mount pad, play support, fixing volume film and put film action; Brake assemblies can be decontroled or stop swelling shaft of stopping the supple of gas or steam.In actual use, need unclamp according to actual needs or swelling shaft of stopping the supple of gas or steam of stopping, make volume film put film or film action is put in stopping.Special on some high efficiency wrapping machine, volume film puts film or stopping, and to put film action more frequent.
In existing technology, mainly contain following several implementation: the film action that veers away of volume film generally adopts damping mode to the film that veers away, namely then walk around brake disc fixing for one end of a belt, finally with an extension spring mode of the other end tensioning of belt hindered and put film, there is a kind of drawback in the film placing mechanism that send of this mode, is exactly that the quality of film is large when film also larger volume, cause inertia when rotating also larger, be difficult to stop at once and there is the situation of putting film more.
Realize veering away with the axle of brake motor Direct driver air-expanding shaft or otherwise tensioning film volume the object of film, this film mode that veers away can reach the object of the film that accurately veers away, but the price of motor can be more expensive than cylinder, the more important thing is the place at some narrow spaces, the volume of motor will be a large problem.Brake assemblies is made up of twin shaft cylinder and brake facing, brake facing is contained in twin shaft air cylinder fixed plate, all by twin shaft cylinder ejector at ordinary times, brake facing is made to be close to action brake disc played and stops putting film, when put the swing arm of film signal provide semaphore request put film time, twin shaft cylinder is retracted with brake facing and is left brake disc, volume film on air-expanding shaft just can put film action, due on some high efficiency wrapping machine, volume film puts film or stopping, and to put film action more frequent, make cylinder frequently be subject to the effect of diametral load, thus greatly shorten cylinder service life.
Utility model content
The purpose of this utility model be a kind of volume film provided for the deficiencies in the prior art send film placing mechanism.
The utility model is achieved by the following technical solution:
A kind of volume film send film placing mechanism, comprise support fixing volume film and put film action volume film supporting component, unclamp and stop stop the supple of gas or steam swelling shaft, make the volume film on air-expanding shaft carry out putting film or stop the brake assemblies of action and control brake assemblies action put film signal swing arm unit, wherein roll up film supporting component and comprise air-expanding shaft assembly, bearing block assembly and air-expanding shaft mount pad, brake assemblies comprises brake disc, brake facing, brake lever, suspension ring and extension spring, put film signal swing arm unit and comprise deep groove ball bearing, swing arm supporting seat, swing arm, drum assembly, air-expanding shaft mount pad is equipped with bearing seat, deep groove ball bearing is had in bearing seat, air-expanding shaft assembly is fixed together through the deep groove ball bearing in bearing seat and brake disc, brake disc is around bearing seat axis rotation, brake facing is fixed in brake lever, one end of brake lever is contained on a little axle on air-expanding shaft mount pad, brake lever is flexibly connected with little axle, the brake lever other end is equipped with suspension ring, suspension ring are equipped with extension spring, brake lever can overcome the pulling force of extension spring and do the swing of certain amplitude with the axle center of axle little on air-expanding shaft mount pad, brake lever pivot shaft is equipped with some deep groove ball bearings, outside deep groove ball bearing, swing arm is housed, a little axle is equipped with in one end of swing arm, little axle is equipped with deep groove ball bearing, when swing arm is with the axis swing of swing arm supporting seat, brake lever can be backed down in the surface of deep groove ball bearing, brake lever is forced to do the swing of certain amplitude, the other end of swing arm is equipped with drum assembly.
Described brake facing profile is circular arc, and radian and the brake disc cylindrical radian of brake facing match.
The beneficial effects of the utility model: the utility model can more effectively, fast speed, frequently start and stop air-expanding shaft, what make volume film veers away film action accurately and reliably, and safety durable, cheap.
