Abstract
The invention discloses an unwinding device and relates to the field of mechanical equipment. The unwinding device comprises a mandrel and a supporting seat; the supporting seat is arranged at one end of the mandrel; a spring is disposed on the mandrel and connected with a taper sleeve; the taper sleeve is fixed to the mandrel through bearings; clamping claws are disposed on the taper sleeve; a sliding sleeve is disposed at the other end of the mandrel; the sliding sleeve is connected with a fastening button; the fastening button is disposed on the end face of the mandrel; the mandrel is connected with a sheave which is provided with a coiled film; when the fastening button is screwed tightly, the sliding sleeve can move rightwards to push the taper sleeve to move axially, the taper surface of the taper sleeve forces the movable clamping claws to perform outward movement in the radial direction, and therefore a packaging material roll is clamped and fastened; when the fastening button is loosened, the sliding sleeve is pushed under the acting force of the spring, the taper sleeve is driven to move leftwards, the clamping claws are made to move inwards in the radial direction to reset, and therefore the material roll is loosened. The unwinding device is in a clamping claw positioning mode, the packaging material roll is fixed through the movable clamping claws, and roll loading and unloading actions are easy and convenient.
Description
Technical field
The present invention relates to technical field of mechanical equipment, be specifically related to a kind of uncoil-stand.
Background technology
The bracing or strutting arrangement of a kind of uncoil-stand and packing volume, flexible rotating on bracing or strutting arrangement is twisted in for installation kit package material, and under the effect of traction rollers, with given speed continuous rotary, pine generate bag, application number is the utility model patent of CN201220239276.1, by arranging a connection piece, drum central axis is connected with motor, realize automatic a kind of debatching of warp knitting cloth, save manpower, again described motor is electrically connected to the frequency converter of described cloth inspecting machine, realize automatic a kind of uncoil-stand and the synchronized rotation of cloth inspecting machine, a kind of debatching better effects if, but, this device is too tight to fixing of material, make handling volume dyskinesia.
Summary of the invention
There is provided a kind of scrolling that loads and unloads to make a kind of uncoil-stand easy easily to solve the problem.
The technical scheme of technical solution problem of the present invention is: a kind of uncoil-stand, comprise mandrel and supporting seat, described pivot shaft is located at one end of mandrel, and described mandrel is provided with spring, described spring is connected with tapered sleeve, described tapered sleeve is fixed on mandrel by bearing, and described tapered sleeve is provided with claw, and the other end of described mandrel is provided with sliding sleeve, described sliding sleeve is connected with tightening button, described tightening button is located on the end face of mandrel, and described mandrel is connected with sheave, and described sheave is provided with volume film.As further improvement, described sheave is connected with locating piece.
The beneficial effect that the present invention has relative to prior art is: in the present invention, movable jaw can insert and give prominence to sleeve surface, when screwing tightening button, sliding sleeve can be made to move right and promote tapered sleeve to move axially, therefore its conical surface forces movable jaw to do the outside shifting movement in footpath, namely radial direction is expanded, thus hold fastening packing volume, when loosening tightening knob, under the force of a spring, promote sliding sleeve, and drive tapered sleeve to be moved to the left, claw footpath is made inwardly to move reset, thus absent-mindedness material webs, adopt a kind of uncoil-stand of claw locate mode, use movable jaw fixing and packaging material webs, handling scrolling is done easy easily, the effect of locating piece makes sleeve axial location.
Accompanying drawing explanation
Fig. 1 is front view of the present invention.
Wherein, 1-locating piece, 2-supporting seat, 3-sheave, 4-spring, 5-rolls up film, 6-mandrel,
7-tapered sleeve, 8-claw, 9-bearing, 10-sleeve, 11-sliding sleeve, 12-tightening knob.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is described in further details.As shown in Figure 1: a kind of uncoil-stand, comprise mandrel 6 and supporting seat 2, described supporting seat 2 is located at one end of mandrel 6, described mandrel 6 is provided with spring 4, described spring 4 is connected with tapered sleeve 7, described tapered sleeve 7 is fixed on mandrel 6 by bearing 9, described tapered sleeve 7 is provided with claw 8, the other end of described mandrel 6 is provided with sliding sleeve 11, described sliding sleeve 11 is connected with tightening button 12, described tightening button 12 is located on the end face of mandrel 6, described mandrel 6 is connected with sheave 3, described sheave 3 is provided with volume film 5, claw 8 can insert and give prominence to sleeve surface, when screwing tightening button 12, sliding sleeve 11 can be made to move right and promote tapered sleeve 7 to move axially, therefore its conical surface forces movable jaw 8 to do the outside shifting movement in footpath, namely radial direction is expanded, thus hold fastening packing volume, when loosening tightening knob 12, under the application force of spring 4, promote sliding sleeve 11, and drive tapered sleeve 7 to be moved to the left, claw 8 footpath is made inwardly to move reset, thus absent-mindedness material webs, adopt a kind of uncoil-stand of claw 8 locate mode, use claw 8 fixing and packaging material webs, handling scrolling is done easy easily.
It should be noted that described sheave 3 is connected with locating piece 1, effect makes sleeve 10 axial location.
Based on above-mentioned, movable jaw can insert and give prominence to sleeve surface, when screwing tightening button, sliding sleeve can be made to move right and promote tapered sleeve to move axially, therefore its conical surface forces movable jaw to do the outside shifting movement in footpath, namely radial direction is expanded, thus hold fastening packing volume, when loosening tightening knob, under the force of a spring, promote sliding sleeve, and drive tapered sleeve to be moved to the left, claw footpath is made inwardly to move reset, thus absent-mindedness material webs, adopt a kind of uncoil-stand of claw locate mode, use movable jaw fixing and packaging material webs, handling scrolling is done easy easily.
The foregoing is only embodiments of the invention; not thereby the scope of the claims of the present invention is limited; every utilize specification sheets of the present invention and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
