Technical Field

[0001] The utility model relates to the technical field of furniture production, in particular to a furniture board grinding device. Background Technique

[0002] Furniture refers to various equipment used in families or offices. There are many types of furniture. During the furniture processing process, it is usually necessary to grind the boards, so a grinding device is required.

[0003] A Chinese patent with the publication number CN215036130U discloses a board grinding device for furniture production and processing, including a fixed table. The top of the fixed table is fixedly connected with a support frame. The left side of the support frame is movably connected with a driving wheel. The left side of the support frame and above the driving wheel is movably connected with a driven wheel. The outer surfaces of the driving wheel and the driven wheel are movably connected with a rotating belt. The left side of the driving wheel and the right side of the support frame are both fixedly connected with a first motor. The opposite sides of the two first motors are both fixedly connected with threaded rods; for this board grinding device for furniture production and processing, by fixedly connecting two first motors on both sides of the support frame, two push plates can fix the board on the fixed table, avoiding the situation that the stability of the board during grinding is not high and affecting the grinding efficiency.

[0004] The existing grinding devices usually grind on one side only. After one side is ground, it is necessary to turn over the board to grind the other side. The operation steps are relatively complex, which greatly reduces the grinding efficiency. Moreover, after the grinding wheel is used for a long time, it will be worn or damaged and needs to be replaced. For the existing grinding devices, the process of replacing the grinding wheel is relatively cumbersome and time-consuming, and it is not convenient to quickly replace the grinding wheel, thus greatly reducing the production efficiency; therefore, a furniture board grinding device is proposed to solve the above problems. Content of the Utility Model

[0006] The technical solution adopted by the present utility model to solve its technical problems is as follows: A furniture board grinding device described in the present utility model includes four support plates; a support frame is fixedly connected between every two support plates, the tops of the two support frames are both fixedly connected with fixing plates, chutes are opened on both fixing plates, sliders are arranged in both chutes, a first rotating cylinder is rotatably installed between the two sliders through a first rotating shaft, a first motor is installed on the side wall of one of the sliders, the output end of the first motor is connected to one end of the first rotating shaft, four first fixing seats are fixed on the outer surface of the first rotating cylinder, a first rotating rod is rotatably installed in each first fixing seat, an upper grinding roller is sleeved on each first rotating rod, a second motor is installed on one side wall of each first fixing seat, the output end of the second motor is connected to one end of the first rotating rod, first pneumatic cylinders are installed on the tops of the two fixing plates, the acting end of the first pneumatic cylinder is equipped with a first pneumatic rod, and the bottom end of the first pneumatic rod is fixedly connected to the slider. Since the grinding wheel will be worn or damaged after long-term use and needs to be replaced, when replacing the upper grinding wheel, start the first motor to operate, so that the first rotating cylinder drives the upper grinding roller to rotate. When the upper grinding roller rotates to the lowest position and is perpendicular to the board, the first motor stops operating, so that the upper grinding roller can be replaced in a timely and rapid manner. When replacing the lower grinding wheel, start the third motor to make the second rotating cylinder drive the lower grinding roller to rotate. When the upper grinding roller rotates to the highest position and is perpendicular to the board, the third motor stops operating, so that the lower grinding roller can be replaced in a timely and rapid manner. This structural design facilitates the replacement of the grinding wheel, and the replacement process is simple and fast, reducing the downtime, thereby improving the production efficiency.

[0007] Preferably, second pneumatic cylinders are installed at the bottom ends of the two support frames. The acting ends of the second pneumatic cylinders are equipped with second pneumatic rods.

[0013] 1. When replacing the upper grinding wheel of the present utility model, start the first motor to operate, so that the first rotating cylinder drives the upper grinding roller to rotate. When the upper grinding roller rotates to the lowest position and is perpendicular to the plate, the first motor stops operating, so that the upper grinding roller can be replaced in a timely and rapid manner. When replacing the lower grinding wheel, start the third motor, so that the second rotating cylinder drives the lower grinding roller to rotate. When the upper grinding roller rotates to the highest position and is perpendicular to the plate, the third motor stops operating, so that the lower grinding roller can be replaced in a timely and rapid manner.

[0028] Working principle: Since the existing grinding device usually grinds on one side only. After grinding one side, it is necessary to turn over the workpiece to grind the other side. The operation steps are relatively complex, which greatly reduces the grinding efficiency. And after the grinding wheel is used for a long time, it will be worn or damaged, and the grinding wheel needs to be replaced. In the existing grinding device, the process of replacing the grinding wheel is relatively cumbersome and time-consuming, and it is not convenient to quickly replace the grinding wheel, thus greatly reducing the production efficiency. Therefore, a furniture plate grinding device is proposed to solve the above problems. Before grinding, start the first pneumatic cylinder 12, so that the first pneumatic rod 13 drives the slider 5 to move downward along the chute 4, and then the upper grinding roller 10 also moves downward until the upper grinding roller 10 moves down to contact the top side of the plate. Then start the second pneumatic cylinder 14, so that the second pneumatic rod 15 drives the mounting seat 16 to move upward, and then the lower grinding roller 21 also moves upward until the lower grinding roller 21 moves up to contact the bottom side of the plate. When the upper grinding roller 10 and the lower grinding roller 21 are adjusted to contact the top side and the bottom side of the plate, when grinding, start the second motor 11 and the fourth motor 22 to make the upper grinding roller 10 and the lower grinding roller 21 rotate. When the plate passes between the upper grinding roller 10 and the lower grinding roller 21, the grinding of the upper and lower sides of the plate can be completed at the same time. Through the operation of double-sided grinding, the grinding efficiency is greatly improved.

[0029] Since the grinding wheel will be worn or damaged after long-term use, it is necessary to replace the grinding wheel. When replacing the upper grinding wheel, start the first motor 7 to operate, so that the first rotating cylinder 6 drives the upper grinding roller 10 to rotate. When the upper grinding roller 10 rotates to the lowest position and is perpendicular to the plate, the first motor 7 stops operating, so that the upper grinding roller 10 can be replaced in a timely and rapid manner. When replacing the lower grinding wheel, start the third motor 18 to make the second rotating cylinder 17 drive the lower grinding roller 21 to rotate. When the upper grinding roller 10 rotates to the highest position and is perpendicular to the plate, the third motor 18 stops operating, so that the lower grinding roller 21 can be replaced in a timely and rapid manner. This structural design facilitates the replacement of the grinding wheel, and the replacement process is simple and fast, reducing the downtime and thus improving the production efficiency.
