Paper-feeding structure in steel coil production

Abstract

The invention provides a paper unloading structure in the production of steel strips, which includes a paper unloading machine, a platform, and a lifting car. The paper unloading machine is located on one side of the platform. On the fixed base, the shaft head mechanism includes a rotating base body and a hanging shaft. The rotating base body is rotatably sleeved on the fixing base and driven to rotate by the rotating mechanism. Both ends protrude relative to each other, and the hanging shaft is provided with a pipe along the axis center, and several groups of air holes are equidistantly distributed on the section where the hanging shaft protrudes relative to the bearing plate, and the lift car is slidably installed on the platform and has a lifting platform . The invention can save the time for changing the paper roll, the paper roll is not easy to rotate relative to the holding shaft, and the roll-up operation is simple and convenient.

Description

technical field [0001] The invention relates to a coiling auxiliary device for steel strip production, in particular to a paper-feeding structure in steel coil production. Background technique [0002] During the coiling process of the steel strip in the winding unit, due to the change of coiling speed and mechanical vibration, etc., the plates of the steel strip will rub against each other, resulting in scratches on the plate surface, which seriously affects the surface quality of the product; Machine mechanism, place and wrap some roll paper on the last few rolls of steel coil materials to prevent the board surface from being bruised. The paper roll is fed through the paper unloading machine. When the paper roll is loaded into the shaft head of the paper unloading machine, there is still some gap between the paper roll and the holding shaft, which will cause the paper roll to be relative to the holding shaft during the paper unloading process.

[0002] During the coiling process of the steel strip in the winding unit, due to the change of coiling speed and mechanical vibration, etc., the plates of the steel strip will rub against each other, resulting in scratches on the plate surface, which seriously affects the surface quality of the product; Machine mechanism, place and wrap some roll paper on the last few rolls of steel coil materials to prevent the plate surface from being bruised

The paper roll is fed through the paper unloading machine. When the paper roll is loaded into the shaft head of the paper unloading machine, there is still some gap between the paper roll and the holding shaft, which will cause the paper roll to be relative to the holding shaft during the paper unloading process. Movement will cause the paper to break easily when unloading the paper. In addition, during the paper unloading process, since the holding shafts of the coiler and the paper unloading machine are always rotating, if the hanging shaft of the paper unloading machine and the roll paper are not tightly installed , it is easy to cause the speed of putting the paper out of sync with the speed of taking the roll, and the paper will break and wrinkle, which will affect the appearance and quality of the board to a certain extent.

[0003] In addition, the current paper unloading machine generally needs to be stopped after a paper roll is placed, and then the paper roll can be reloaded after the paper roll is placed on it. Since the current finished steel coil is very fast, a roll of material will be curled soon. As a result, the speed of changing paper rolls cannot keep up

Moreover, the current design of the paper unwinding machine is to fix the paper unwinding machine on the winder, resulting in a height of 2-3 meters from the shaft head of the paper unloading machine to the ground, and the paper cylinder generally weighs 300-500 kg, which is manually transported to the shaft head It is difficult to install. Generally, the crane is used for hoisting, then aligning the shaft head, and then pushing the paper tube. This operation requires alignment of the shaft head, frequent use of driving and manual assistance. The operation is difficult, the labor intensity is high, and there are certain danger
