Description

Hand pressure sander with height adjusting function

Technical field

It the utility model is related to sheet fabrication field, more particularly to a kind of hand pressure sander with height adjusting function.

Background technology

Sheet material is raw material important in all kinds of Furniture manufacturings, usually requires to beat plate surface after the completion of cutting Grind to meet the surface smoothness required by japanning, welt or welt processing.At present, in the prior art by sander to plate Material surface is polished, and the sander for being polished plate surface is broadly divided into manual sander and automatic sander two Class.Manual sander is polished plate surface mainly by the manual mode of worker, and equipment manufacturing cost is low, is adapted to middle-size and small-size Enterprise uses.

The existing Chinese patent for referring to Publication No. CN205415227U, it discloses a kind of entitled one kind to be used for The manual sander of wardrobe cabinet door, including frame and workbench are processed, is symmetrically arranged with and column phase on the inside of two columns of frame Vertical guide rod, workbench are slidably disposed on guide rod vertically, and mechanism of sanding machine, sanding are provided with above workbench Mechanism includes abrasive band, driving wheel, driven pulley, breast wheel, the motor for driving driving wheel, and driving wheel and driven pulley are symmetrical arranged On two columns of frame, breast wheel is arranged on the entablature of frame, and breast wheel is located at the middle part of entablature, the active Connected, be provided with below entablature for by the working face and workbench in abrasive band by abrasive band between wheel, driven pulley, breast wheel The hold-down mechanism of end contact, the dust shield being connected with dust exhaust apparatus is respectively fixed with two columns of frame, two dust shields Mouth end is opposite, and driving wheel and driven pulley are respectively corresponding in dust shield.It is manually operated by the pressing device of below the crossbeam Pressing device, the working face in abrasive band is contacted with workpiece surface, realize that sanding acts on.Although its low cost, accommodate middle-size and small-size Enterprise uses.

But when the blocked up gap beyond between worktable upper surface and abrasive band of the sheet metal thickness for needing to process, it can not carry out Sanding works, when needing to process than relatively thin workpiece, due to workpiece surface apart from abrasive band working face farther out, sand during pressing Abrasive band is caused to damage with larger deformation is produced, so sander of the prior art and impracticable.

Utility model content
