Embodiment Construction

[0009] The present invention is described in further detail now in conjunction with accompanying drawing. These drawings are all simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, so they only show the configurations related to the present invention.

[0010] Such as figure 1 The specific embodiment of the shown constant tension unwinding machine of the present invention, it comprises frame 1 and motor speed reducer 2, frame 1 two ends are provided with unwinding shaft 3, unwinding shaft 3 is provided with sprocket 8, puts There is a pinch roller 5 between the reels 3, and the unwinding reel 3 is connected with the motor reducer 2 through a chain transmission. One of the transport rollers 6 is equipped with a pressure sensor 7.

[0011] Cloth rolls are placed on the two unwinding shafts 3, and the two rolls of cloth rolls can be unwound alternately. When one roll of cloth roll is unrolled, the other roll o...

Abstract

The invention relates to an unreeling machine, in particular to a constant-tension unreeling machine. The constant-tension unreeling machine comprises a rack and a motor reducing gear; unreeling shafts are arranged at the two ends of the rack; chain wheels are arranged on the unreeling shafts; a clamping roller is arranged between the unreeling shafts; the unreeling shafts is connected with the motor reducing gear in a transmission way through chains; a transfer roller group is arranged at the position of a base of the rack; a vector frequency converter is arranged on the motor reducing gear; and a pressure sensor is arranged on one transfer roller in the transfer roller group. The unreeling machine solves the technical problem that the conventional unreeling machine cannot conveniently and effectively maintain a constant tension in an unreeling process, controls the linear velocity of materials when unreeling by arranging the vector frequency converter on the motor reducing gear to make the material unreeling linear velocity constant, and ensures the constant tension of the unreeling machine when unreeling.

Description

technical field [0001] The invention relates to an unwinding machine, in particular to a constant tension unwinding machine. Background technique [0002] Coil processing (such as: steel coil, paper roll, fabric roll, etc.) is a method widely used in automation and mass processing, and unwinding is a necessary process. During the unwinding process of the unwinding machine, the tension will also change with the gradual change of the roll diameter. When the tension is not constant, when the winding is unrolled, it will relax due to the tension being too loose or the coil will be extended due to the tension being too tight. In this way, when the unrolled material enters the next process, Surface unevenness. During the unwinding process of the existing unwinding machine, in order to maintain a constant tension, it is necessary to control the tension on the winding through the brake at the unwinding mechanism, so that during the production operation, the staff must constantly a...
