Description

Technical Field

[0001] The utility model relates to the technical field of embossing equipment, in particular to a synchronous lifting device for an embossing roller. Background Art

[0002] In the production and processing of asphalt damping plates, embossing roller equipment is needed to complete the product coating work. Due to the difference in product thickness, the roller spacing needs to be adjusted when each product is produced. The existing equipment is to install a worm gear lifter on each side of the embossing roller. When adjusting the roller spacing, two people are required to adjust the lifter on both sides of the embossing machine to meet the process requirements. The worm gear lifter usually has an electric motor or a manual device (such as a hand-cranked brake lever) as a power input source to drive the worm gear screw lifter; and the power input source first drives a worm, that is, a spiral-shaped gear; the worm meshes with the worm wheel (a gear with internal teeth) through its linear spiral tooth surface; a screw (also called a screw rod or screw) is fixed at the center of the worm wheel. When the worm wheel rotates, the nut on the screw (or a matching component) will rise or fall according to the rotation direction of the worm wheel. Usually, the screw is fixed and does not rotate, but the nut moves up and down to achieve the lifting and lowering of the load; the linear motion brought by the lifting mechanism is converted into the lifting and lowering of the heavy object through the load-bearing platform or fixture connected to the screw.

[0003] At present, most of the embossing roller equipment used in the production of asphalt damping plates will need to be replaced due to wear or pattern change during long-term use. However, the embossing roller in the existing embossing device is usually fixed by bolts, which makes it inconvenient to disassemble when it needs to be inspected, maintained or replaced, which makes it inconvenient to use and has relatively poor practicality.
