Description
Technical Field
The utility model relates to a cutting machine unwinding device technical field, in particular to novel unwinding device.
Background
In aluminium foil paper manufacturing enterprise, the feeding that the tradition was used for the cutting machine unreels adopts and places a pivot on a support frame, then fixes whole roll of material in the pivot, and the blowing as required under the traction action of the winding mechanism that sets up at the other end.
However, in the actual use process, it is found that, because there is no braking measure in the unwinding process, the phenomena of too much unwinding and too fast unwinding often occur due to material inertia, and the too much unwinding and the too fast unwinding may be overstocked together to affect feeding. Moreover, the phenomenon that the diameter of the material roll is smaller and smaller along with the unwinding process, and the phenomenon that the unwinding is too fast and too much is more obvious, influences the normal and orderly operation of the subsequent slitting.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is to provide a novel unwinding device, the phenomenon is put and put soon to the mistake that appears when can effectively solve unreeling.
In order to solve the technical problem, the utility model discloses a technical scheme does:
a novel unwinding device comprises a group of support frames, a rotating shaft and an unwinding roller, wherein the support frames, the rotating shaft and the unwinding roller are arranged in parallel; the top of the support frame is movably provided with a rotating shaft; the outside of the rotating shaft is sleeved with a unreeling roller; the unwinding material is wound outside the unwinding roller; the unwinding brake mechanism is composed of a pressing piece and an elastic piece; the bottom end of the pressing piece is movably hinged to the lower part of the supporting frame, the upper part of the pressing piece is lapped on the outer wall of the unreeled material, and an included angle between the pressing piece and the horizontal plane is an acute angle; one end of the elastic piece is fixedly connected with the pressing piece, and the other end of the elastic piece is fixedly connected with the supporting frame.
Further, the pressing piece is rod-shaped or plate-shaped.
Further, the elastic part is a telescopic spring.
Furthermore, one end of the rotating shaft extends to the outside of the supporting frame, and the end part of the rotating shaft is connected with a power driving mechanism.
Further, the support frame is in an isosceles triangle shape.
The utility model has the advantages that:
by adopting the technical scheme, when the unreeling material is unreeled, the unreeling brake mechanism is arranged, and the pressing piece in the unreeling brake mechanism continuously presses the unreeling material, so that the phenomenon that the unreeling material is too fast and too much due to inertia can be avoided, the orderly unreeling process is ensured, and the unreeling process is more stable.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
In the figure, 1-a support frame, 2-a rotating shaft, 3-an unreeling roller, 4-unreeled materials, 5-a pressing piece and 6-an elastic piece.
Detailed Description
The following describes the present invention with reference to the accompanying drawings. It should be noted that the description of the embodiments is provided to help understanding of the present invention, but the present invention is not limited thereto. In addition, the technical features related to the embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.
As shown in fig. 1, a novel unwinding device includes a group of support frames 1 arranged in parallel, a rotating shaft 2 and an unwinding roller 3; the top of the support frame 1 is movably provided with a rotating shaft 2; the outside of the rotating shaft 2 is sleeved with a unreeling roller 3; an unreeling material 4 is wound outside the unreeling roller 3; the device also comprises an unwinding brake mechanism, wherein the unwinding brake mechanism consists of a pressing piece 5 and an elastic piece 6; the bottom end of the pressing piece 5 is movably hinged to the lower part of the support frame 1, the upper part of the pressing piece 5 is lapped on the outer wall of the unreeled material 4, and an included angle between the pressing piece 5 and the horizontal plane is an acute angle; one end of the elastic piece 6 is fixedly connected with the pressing piece 5, and the other end of the elastic piece is fixedly connected with the support frame 1.
It should be noted that, in practical application, the weight of the pressing member 5 should not be too light and should not be too heavy, and if the weight is too light, the braking effect of the pressing member 5 on the unreeled material is weak, so that the effect can be weakened; if the weight is too heavy, the power consumption of the front winding mechanism is increased. The person skilled in the art can reasonably select the pressing piece 5 with proper weight according to the amount of the unreeled material 4,
further, the pressing member 5 has a rod shape or a plate shape. The pressing piece with the plate-shaped structure has a larger contact area with the unreeling material 4, so that the braking effect is better.
Further, the elastic member 6 is a telescopic spring. The raw materials of the extension spring are easy to obtain and the price is low.
Furthermore, one end of the rotating shaft 2 extends to the outside of the support frame 1, and the end part is connected with a power driving mechanism. A person skilled in the art can drive the rotating shaft 2 to rotate for unreeling by arranging a power driving mechanism according to production requirements.
Further, the support frame 1 is in an isosceles triangle shape. The isosceles triangle-shaped support frame 1 is good in stability and convenient to mount an unwinding brake mechanism.
The utility model discloses a working process:
during the operation, the utility model provides an unreel material 4 by with the utility model discloses in unreel device complex winding mechanism pull and unreel, unreel the in-process, owing to be provided with and unreel arrestment mechanism, unreel among the arrestment mechanism compress tightly 5 and continuously press on unreeling material 4, so can avoid unreeling material 4 owing to inertia leads to unreeling too fast, too much phenomenon to guaranteed the orderly the going on of unreeling, makeed the process of unreeling more stable.
The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. It will be apparent to those skilled in the art that various changes, modifications, substitutions and alterations can be made in the embodiments without departing from the principles and spirit of the invention, and the scope of the invention is to be accorded the full scope of the claims.
