Description

A high stability and high precision metal strip uncoiler

technical field

The utility model relates to an uncoiler, in particular to an uncoiler for wide metal strips.

Background technique

The metal strip uncoiler is the most widely used equipment in the metal strip production and processing industry. The entire metal strip is placed on the reel of the uncoiler. In order to achieve the accuracy of strip unwinding, the absolute support of the reel to the metal coil must be controlled. At present, the reel of the uncoiler mainly adopts the tensioning shaft, which realizes the support, unwinding and changing of the metal coil through the tensioning shaft. Metal strips are different from other coils in that the mass of the entire coil is heavier, and the requirements for the uncoiler are extremely high, and the stability of the uncoiling process is one of the difficulties in technical control.

Utility model content

The technical problem to be solved by the utility model is to provide a metal strip uncoiler for the above-mentioned prior art, aiming at the unwinding operation of the metal strip, improving the unwinding precision and the stability of the equipment operation.

The technical solution adopted by the utility model to solve the above problems is: a high-stability and high-precision metal strip uncoiler, including a box body and a main shaft erected on the box body, the rear end of the main shaft is supported on the box body, and the main shaft The front end is extended, and the front end of the main shaft is set with a tensioning sleeve for supporting the metal strip coil. A speed-regulating motor and a reducer are installed on the box. The reducer drives the main shaft to rotate through a coupling. The outer end of the main shaft An auxiliary support is provided, and a pressing device is arranged above the tensioning sleeve; the auxiliary support includes a first connecting rod, a second connecting rod, several auxiliary connecting rods and a telescopic cylinder, and the front end of the first connecting rod is connected to the The front end of the main shaft is connected, the rear end is connected with the upper end of the second connecting rod, and the lower end of the second connecting rod is used as a connection support with variable angle, and the telescopic cylinder is connected with the second connecting rod through several auxiliary connecting rods; the pressing device It includes a movable nip roller, which can contact and press the metal strip coil supported on the tensioning shaft sleeve.

Specifically, the pressing device includes a swing rod, the rear end of the swing rod is connected to the telescopic cylinder, the front end of the swing rod is provided with the pressing roller, and the swing rod is hinged on the support beam. The telescopic cylinder drives the pendulum, and the pendulum swings with the hinged position as the fulcrum to adjust the nip roller to ensure that the nip roller always presses the metal strip roll during the operation.

Preferably, the lower end of the second connecting rod is shaped as a connecting hook, which is hooked with a mechanism on the work site to provide stable support.

Compared with the prior art, the utility model has the advantages of: providing an uncoiler, by setting a pressing device above the tensioning bushing to ensure the accuracy of uncoiling and avoid loosening, and setting an auxiliary support at the front end of the main shaft to ensure unwinding The stability of the rolling process avoids shaking and provides a guarantee for the high stability and high precision unwinding of wide metal strips.
