Rolling machine for escalator apron panel

Abstract

The invention discloses an edge roller, which is strong in universality, high in edge rolling precision and free of scratches on surface, for an escalator skirt guard panel. The edge roller comprises a rack (1), and further comprises an integral platform, wherein a drive device is arranged on the rack (1); a drive shaft and a driven shaft above the drive shaft are arranged on the drive device; roller wheels (2) for edge rolling are fixed on the drive shaft and the driven shaft to form edge rolling parts; an opening is formed in one side of the integral platform; the rolling part is positioned in the opening; the integral platform comprises a supporting plate (3), a height adjustable mechanism, a cover plate (4) and a ball unit; the ball unit comprises a ball cover (8), a ball base (9), a ball body (10); the ball body (10) and the ball base (9) are arranged in the ball cover (8); the cover body (4) and the supporting plate (3) are connected up and down for pressing and fixing the ball cover (8) on the supporting plate (3); a through hole for locally expositing the ball body (10) is formed in the ball cover (8).

Description

technical field [0001] The invention relates to the technical field of hemming equipment structure, in particular to a hemming machine for an escalator apron board. Background technique [0002] The escalator is the escalator, which is generally relatively long, so the escalator apron board is not a whole piece, but is made up of multiple boards spliced ​​in sequence. The shape of the multiple boards will change due to the extension of the escalator along its length. There are shapes such as rectangular boards and fan-shaped boards, so when hemming, it is necessary to hem boards of different shapes. The ideal state is a hemming machine, which can be applied to both rectangular boards and fan-shaped boards. However, the existing The hemming machine is not suitable, for example, the Chinese patent plate hemming machine with the authorized announcement number CN202180122 U, in order to be versatile, the simple improvement is to increase the contact area between the board and th...

[0002] The escalator is the escalator, which is generally relatively long, so the escalator apron board is not a whole piece, but is made up of multiple boards spliced ​​in sequence. The shape of the multiple boards will change due to the extension of the escalator along its length. There are shapes such as rectangular boards and fan-shaped boards, so when hemming, it is necessary to hem boards of different shapes. The ideal state is a hemming machine, which can be applied to both rectangular boards and fan-shaped boards. However, the existing The hemming machine is not suitable, for example, the Chinese patent plate hemming machine with the authorized announcement number CN202180122 U, in order to be versatile, the simple improvement is to increase the contact area between the board and the support platform, so that although the board can be well supported, it will not It is well supported and the board is not easy to be pushed. In order to push the board, it is necessary to apply a greater driving force. Larger driving force will make the board prone to deformation and surface scratches. These details are very important. Otherwise, if the board is deformed, it will inevitably affect the binding Accuracy, scratches on the surface will lead to obvious defects in the product, which is also unacceptable. At the same time, the vibration of the board should be controlled as small as possible to facilitate the accuracy of the hemming. Based on the above, if we can develop a universal, At the same time, the hemming machine for escalator apron panels with high hemming precision and no scratches on the surface will be of great significance for reducing production costs and labor intensity and improving production efficiency.
