Bottom surface sanding machine

Abstract

The invention belongs to the field of sanding machines, and particularly relates to a bottom surface sanding machine. The bottom surface sanding machine comprises a machine frame, a workbench, sanding racks and sanding rack motors, wherein the workbench, the sanding racks and the sanding rack motors are arranged on the machine frame. The bottom face of the workbench is a working face. A lifting platform capable of moving up and down along the machine frame through a lifting assembly is arranged below the workbench. The sanding racks are fixedly arranged on the lifting platform. The sanding rack motors are erected above the workbench through rack rods with the bottom ends fixedly arranged on the lifting platform. According to the bottom surface sanding machine, the workbench located above is motionless, and the lifting platform located below can drive the sanding racks to move up and down, so that the lifting platform of the sanding machine is directly matched with a workbench located below of an existing top surface sanding machine, and synchronous lifting can be realized; hence, under the premise that there is no need to widen a workshop and to be additionally provided with a transition conveying table, an existing top surface sanding machine manufacturer can achieve direct butt joint with the original top surface sanding machine with low capital investment after the bottom surface sanding machine is additionally arranged, and then the effect of sanding two surfaces with one-time feeding can be achieved.

Description

technical field [0001] The invention belongs to the field of sanding machines, and in particular relates to a bottom sanding machine. Background technique [0002] The existing sanding machines on the market and 90% of the factories are top-surface sanding machines, that is, the sanding machine with the worktable below and the sand frame above. The worktable can be moved up and down to adapt to different thickness of the board. , if double-sided sand is needed during use, it is necessary to first sand the top and then turn over the plate sand, such as a kind of sanding machine disclosed by the authorized announcement number CN 202668274 U, including a frame, which is provided with a workbench and a workbench There is a transmission device for sheet material transmission inside, a dust cover and a dust sweeper are provided on the workbench, and a pressing roller and a grinding device are arranged inside the dust cover. This sander is a traditional existing top surface sander...

AI Technical Summary

Problems solved by technology

[0003] If you want to avoid the process of flipping the plate, you need to add an existing bottom sander. The worktable of the sander is on the top and the sand frame is on the bottom. Also, the worktable moves up and down to adapt to different thicknesses. Plates, but because different plates have different thicknesses and can only be raised and lowered by the workbench, the top sander and bottom sander cannot directly match plates of different thicknesses. It is necessary to add two ends and two machines between the two machines The hinged length is at least longer than the length of the plate (at least two to three meters in length), which not only makes the whole set of equipment occupy a large area, but also greatly increases the cost

Now there are also some integrated whole machine plates that can be directly sanded on both sides, but the cost of this equipment is much higher than the current top sander or bottom sander, and most of the small factories have the original top sander It will be discarded, which not only causes a waste of resources, but also increases the production cost of the enterprise due to the large purchase cost. Generally, small factories will choose to use the original equipment
