Abstract
The utility model provides an abrasive belt polisher, and belongs to the technical field of machines. The problems that scraps produced by an existing abrasive belt polisher are scattered in an encloser and easily accumulate in the encloser as the scraps are heavy and cannot be sucked away through a dust chimney are solved. The abrasive belt polisher comprises a rack and a working table arranged on the rack. A driving wheel, a driven wheel and a polishing belt are arranged in the working table, and the driving wheel and the driven wheel are sleeved with the polishing belt. The lower portion of the working table is hinged to the rack and can rotate relative to the rack. The working table is provided with an operating mouth allowing a workpiece to make contact with the polishing belt. The position, below the operating mouth, of the rack is connected with a dust hopper. A baffle mechanism is connected between the working table and the rack, the baffle mechanism can stretch out and draw back freely and can guide dust produced during polishing into the baffle mechanism of the dust hopper. Being provided with the dust hopper and the baffle mechanism, the abrasive belt polisher can effectively prevent scraps from diffusing and scattering. The baffle mechanism can guide the scraps into the dust hopper, and therefore the effects of collecting dust and the scraps are good.
Description
Technical field
The utility model belongs to field of mechanical technique, relates to a kind of belt sander.
Background technology
Dust, chip that existing belt sander produces during to operation all do not do special protective treatment, easily cause air pollution and the injury to operating personnel.More general processing mode is at a polishing wheel outside protective cover of cover or below polishing wheel, arranges one for catching the dust hopper of whereabouts dust; but these two kinds of modes are all relatively backward; treatment effect to dust is limited, can not prevent well dust diffusion.
As the utility model patent [patent No. 200810059165] of the polishing machine of a kind of improvement of Patent Office of the People's Republic of China's announcement, introduce a kind of measure of effective processing dust.This polishing machine comprises a frame and is arranged on the workbench in frame, workbench be provided with driving wheel, driven pulley and be enclosed within driving wheel and driven pulley on sand belt.The lower hinge of workbench, in frame, is provided with the detent mechanism that can prevent that workbench from swinging around its hinged place between workbench and frame.On workbench, be provided with the outer cover with gathering hole, driving wheel, driven pulley and sand belt are all positioned at outer cover, and outer cover bottom is provided with two dust flues that communicate with outer cover, and the entrance point of these two dust flues has the initiative respectively and takes turns and driven pulley place.While carrying out polishing, workpiece is disposed on sand belt by gathering hole, can be stoped the dust producing in polishing process to spread to the external world by outer cover, and siphon away the dust of outer cover inner accumulated by dust flue.The shortcoming of this structure is exactly to clear up heavier chip, and these chips are scattered in outer cover, cannot siphon away by dust flue, so easily accumulation and clear also inconvenient in outer cover because quality is heavy.
