Description
Technical Field
[0001] This utility model relates to the field of sprue processing, and in particular to a sand belt grinding device for sprues. Background Technology
[0002] In industrial production, especially in the manufacturing of injection molded parts and castings, sprue marks are excess parts left after product molding. They need to be ground to ensure the product's appearance quality and performance. A belt abrasive sprue grinding device uses the high-speed movement of an abrasive belt to grind the sprue marks, thereby removing them and finishing the product surface.
[0003] Existing belt abrasive sprue grinding devices mostly use a cylinder push-pull method for vertically adjusting the position of the grinding workpiece and the sprue. However, since the grinding workpiece is usually quite heavy, the cylinder must be designed to be large enough to move it vertically. This directly leads to a significant increase in the weight of the entire device, making it inconvenient to transport and install, and placing higher demands on the load-bearing capacity of the placement site. Furthermore, the large cylinder occupies a significant amount of internal space, making the internal component layout crowded. When the device malfunctions and requires maintenance, it is difficult for personnel to access critical internal parts, greatly increasing the difficulty and time cost of maintenance, thus presenting significant limitations.

[0023] In this embodiment, after adjusting the sprue position, the grinding component needs to be adjusted and the grinding operation started.

The vertical sliding of the lead screw will push the rotating plate 34 to rotate around the central rotation point, thereby driving the grinding component at the top of the rotating plate 34 to rise and fall, adjusting the sanding belt 39 to a suitable height for contact with the sprue. Then, the asynchronous motor 35 is started, which drives the first guide wheel to rotate. The first guide wheel drives the second guide wheel to rotate through the transmission belt 36. The sanding belt rotating rubber wheel 38, which is fixed to the second guide wheel, rotates accordingly. The sanding belt 39 moves at high speed under the action of the sanding belt rotating rubber wheel 38 and the transmission wheel to grind the sprue. During the grinding process, the height of the grinding component can be finely adjusted by the servo motor 31, and the position of the sprue can be finely adjusted by the first motor 221 and the second motor 224 to ensure the grinding quality.
