A sand frame device with rotation and revolution

Abstract

The invention provides a sand frame device with rotation and revolution. The sand frame device comprises a flange plate, wherein a rotation driving wheel and a revolution driving wheel are sequentially mounted above the flange plate, the rotation driving wheel is fixedly connected with a rotation shaft, a rotation synchronizing wheel is connected to the lower tail end of the rotation shaft, the rotation synchronizing wheel is connected with a rotation small wheel through a transmission belt, a transmission shaft of the rotation small wheel is connected with a transmission case, the revolution driving wheel is fixedly connected with a revolution cylinder, the rotation shaft can penetrate the interior of the revolution cylinder, and the revolution cylinder is respectively sleeved on a first bearing and a second bearing. In such a way, during the rotation of the rotation driving wheel, the rotation synchronizing wheel on the rotation shaft can be driven to rotate so as to drive the transmission belt to drive the rotation small wheel to rotate, further drive the transmission shaft to rotate and drive a grinding wheel assembly to rotate; and during the rotation of the revolution driving wheel, the revolution cylinder can be driven to rotate independently according to the sequence of the first bearing, the second bearing and a deep groove ball bearing and the grinding wheel assembly can be driven to revolute together, so that multi-direction comprehensive grinding of plates or doors can be effectively realized.

Description

technical field [0001] The invention relates to a woodworking sander, in particular to a sand frame device mounted on the sander that can rotate and revolve independently, and the rotation and revolution are independent of each other, belonging to woodworking machinery processing equipment. Background technique [0002] Sanding machines are widely used to polish the surface of products, including artworks or various furniture, plates, etc. The sand frame device of traditional sanding machines is usually to install disc sand or round roller sand on the output shaft of the motor. , the plate or door passes on the disc sand or roller sand, so as to polish the surface of the plate or door smooth, however, this grinding method can only be in the forward or backward flow direction, for flow operation in a single direction, only It can meet the position of the plate or door industry that is easy to contact with the disc sand or roller sand. If the steps or side edges of the plate o...

[0002] Sanding machines are widely used to polish the surface of products, including artworks or various furniture, plates, etc. The sand frame device of traditional sanding machines is usually to install disc sand or round roller sand on the output shaft of the motor. , the plate or door passes on the disc sand or roller sand, so as to polish the surface of the plate or door smooth, however, this grinding method can only be in the forward or backward flow direction, for flow operation in a single direction, only It can meet the position of the plate or door industry that is easy to contact with the disc sand or roller sand. If the steps or side edges of the plate or door cannot be polished, manual operation is required. Usually, people will use a portable grinder. The above-mentioned places that have not been polished by disc sand or round roller sand are polished one by one. This operation directly causes the problem of time-consuming and labor-intensive, which leads to an increase in production costs.
