Description

Technical Field

[0001] The utility model relates to the technical field of plate processing, in particular to a plate pre-milling device. Background Art

[0002] The main function of the plate pre-milling equipment is to fine-grind the edge of the plate before edge banding to ensure that the edge of the plate is smooth and burr-free, thereby ensuring the edge banding effect. Because the edge of the plate may not be smooth enough during cutting, causing edge collapse, the pre-milling function can cut the edge of the workpiece to prevent edge collapse. Similarly, if there is glue on the edge of the re-edge-banded plate, you can also mill off a little without affecting the product quality to achieve a better edge banding effect;

[0003] Most of the existing plate pre-milling methods use a pre-milling cutter to process the side of the plate. When the pre-milling cutter is processing, the position of one plate is relatively fixed. When the plate conveying position changes, it is necessary to manually adjust the angle and position of the pre-milling cutter. Secondly, when pre-milling plates of different thicknesses, it is necessary to replace pre-milling cutters of different sizes. The operation is relatively cumbersome and affects the pre-milling efficiency. For this reason, the utility model provides a plate pre-milling device. Utility Model Content

[0020] like Figure 1 and 3 As shown, a top connecting plate 3 is commonly installed at the top ends of the two fixing seats 1, and the fixing seats 1 and the top connecting plate 3 are fixedly connected by screws and bolts, and a fixing cover 4 is installed at the upper end of the top connecting plate 3. Two dust suction ports 5 for sucking pre-milling debris of the plate are opened on the top of the fixing cover 4, and the two dust suction ports 5 correspond to the two driving motors 9 respectively. The top ends of the two dust suction ports 5 are connected to an external dust suction device through a pipe. When the grinding wheel 91 grinds and pre-mills the side of the plate, the debris generated by the grinding can be sucked by the external dust suction device and discharged by the dust suction port 5, thereby improving the waste chip cleaning effect.

[0021] Adjustment grooves 31 are provided on the upper surface of the top connecting plate 3 corresponding to the output ends of the two driving motors 9.

The grinding surfaces of the two grinding wheels 91 and the edge to be pre-milled of the plate are on the same horizontal line. When the adjusting cylinder 7 is extended and retracted to push the driving motor 9 to move forward and backward, the driving motor 9 will drive the grinding wheel 91 to move forward and backward, that is, to approach the edge to be pre-milled of the plate. Therefore, the distance between the grinding wheel 91 and the side of the plate can be adjusted according to the position of the plate to improve the pre-milling effect.

[0022] The working principle of the utility model is as follows: during installation, the fixing seat 1 is installed on the vertical plate of the plate edge banding machine through the cooperation of the mounting plate 2 and the bolts, so that the edge to be pre-milled of the plate and the grinding wheel 91 are in the same horizontal plane, and according to the position of the plate, the adjusting cylinder 7 is started to control its extension and contraction, and the driving motor 9 is pushed to move toward the plate, and the driving motor 9 is stably adjusted through the cooperation of the slide seat 6 and the limit slide bar 8, and its output end drives the grinding wheel 91 to move in the adjusting groove 31 toward the side of the plate, so that the grinding surface of the grinding wheel 91 is close to the edge to be pre-milled of the plate, and then the two driving motors 9 are synchronously controlled to work, and then the two grinding wheels 91 are synchronously driven to work, so as to realize the pre-milling of the side of the plate, remove the burrs on the side of the plate, and improve the subsequent edge banding operation of the plate;

[0023] When the grinding wheel 91 processes the side edge of the plate, the waste chips generated are sucked out through the dust suction port 5, so that the waste chips are processed in time, and the automatic pre-milling process is adopted to improve the work efficiency.
