Sander working platform automatic lift adjuster

Abstract

The invention discloses an automatic lifting adjuster of a working platform of a sanding machine. A sanding band center support is arranged at the upper end of a machine frame, a sanding band tensioning roll is arranged at the upper end of the sanding band center support, a sanding band drive shaft is arranged at the lower end of the sanding band center support, a sanding band drive roll is arranged on the sanding band drive shaft, a sanding band is arranged on the sanding band drive roll and the sanding band tensioning roll, the working platform is arranged at the lower end of the sanding band drive roll, a front support is arranged at the front end of the working platform, a back support is arranged at the back end of the working platform, a conveying belt front tensioning roll is arranged on the front support, a conveying belt back drive roll is arranged on the back support, a conveying belt is arranged on the conveying belt front tensioning roll and the conveying belt back drive roll, two front automatic lifting adjusters are arranged at the lower end of the front support, and two back automatic lifting adjusters are arranged at the lower end of the back support. During operation, when thick base plates enter, rubber adjustment pads arranged in the automatic lifting adjusters contract, are thinned and drive the working platform to descend automatically, and a good working gap is constantly reserved between the base plates and sanding bands.

Description

Technical field [0001] The invention relates to a lifting regulator, to be precise, an automatic lifting regulator for a working platform of a sanding machine. Background technique [0002] Plywood is the main material for construction and decoration. With the development of my country’s economic construction and the continuous improvement of people’s living standards, the demand for common plywood for construction and decoration is increasing. The substrate in the middle of the plywood is composed of several veneers after heating. The plywood must be sanded on the surface of the substrate before being laminated. Then glue the panels on the upper and lower surfaces of the substrate. Because the veneer products come from different manufacturers, the thickness of the veneer produced by thousands of manufacturers is different, so the thickness of the substrate produced varies greatly, and the surface of the board is uneven. The work of the existing sanding machine The platform has ...

AI Technical Summary

Problems solved by technology

Since the veneer products come from different manufacturers, thousands of households produce veneers of different thicknesses, so the thickness of the produced substrates varies greatly, and the surface of the board is uneven, while the existing sanding machine works The platform does not have an automatic lifting adjustment function. The gap between the working platform and the sanding belt needs to be adjusted manually. Due to the slow response speed of the manual, the operation often cannot keep up with the change of the thickness of the substrate. When entering a thicker substrate , the resistance suddenly increases, and it is too late to lower the working platform manually, the speed of the sander drops sharply, and even stops or burns the motor. normal operation, reducing the service life of the equipment
