Description

Technical Field

[0001] The invention relates to the technical field of wood processing, in particular to a wood grinding machine used for producing resin solid wood furniture. Background Art

[0002] Solid wood furniture refers to furniture made of solid wood. Since there will be many burrs in the cutting process, in order to improve the grade of the whole furniture, it is usually necessary to grind the surface of the cut board to remove the burrs on the surface, and then assemble and paint the polished board to make the overall feel and flatness of the solid wood furniture better.

[0003] However, common plate grinders can only grind one side of a plate during use, which has low efficiency. Some grinders also add grinding rollers to improve grinding efficiency and grind multiple sides of a plate at the same time.

[0021] like Figures 1 to 8As shown, an embodiment of the present invention provides a wood sanding machine for the production of resin solid wood furniture, including a frame 100, a conveying mechanism, a bracket, a power mechanism and a sanding belt 130. The frame 100 is fixedly arranged, and the conveying mechanism is arranged on the frame 100, and is used to convey a plate in a first direction, and the first direction is parallel to the horizontal direction; the bracket is arranged on the frame 100, and the plate is arranged in the bracket. The power mechanism includes a power assembly, a first cross bar 101 and a second cross bar 102, the power assembly is arranged on the frame 100, the first cross bar 101 and the second cross bar 102 are arranged on the power assembly, the first cross bar 101 and the second cross bar 102 are respectively located on both sides of the bracket in the first direction, and the first cross bar 101 and the second cross bar 102 both extend in the second direction, and the second direction is a horizontal direction and perpendicular to the first direction; the sanding belt 130 is sequentially wound around the first cross bar 101 and the second cross bar 102, and the sanding belt 130 is sequentially wound around the first cross bar 101 and the second cross bar 102. The first cross bar 101 and the second cross bar 102 are divided into two sides, one of which is wound on the bracket in a positive spiral, and the other is wound on the bracket in a counter-spiral. The spiral axis of the grinding belt 130 wound on the bracket extends along the first direction. Abrasives are provided on both sides of the grinding belt 130. The grinding belt 130 is used to grind the plate in the bracket. The power assembly can drive the grinding belt 130 to circulate on the bracket through the first cross bar 101 and the second cross bar 102 and keep the grinding belt 130 in a taut state.

[0022] A grinding belt 130 is arranged on the bracket. The grinding belt 130 is wound around the bracket by utilizing its flexible characteristics, so that multiple surfaces of the plate can be ground. Through the coordinated arrangement of the first cross bar 101, the second cross bar 102 and the grinding belt 130, the grinding belt 130 circulates on the bracket, thereby improving the uniformity of the grinding of multiple surfaces of the plate by the grinding belt 130; through the bidirectional spiral arrangement of the grinding belt 130 on the bracket, the grinding belt 130 has two relative rotation directions on the bracket, and can perform staggered grinding on the surface of the plate, thereby reducing the residual marks of a single grinding direction on the surface of the plate, and improving the grinding quality of the surface of the plate.

[0023] In this embodiment, the bracket includes a plurality of adjustment components, each of which corresponds to an edge of the plate extending along the first direction, and each of which includes a driving unit, a steering rod 114 and a shrinking unit. The driving unit is arranged on the frame 100, and the steering rod 114 is arranged on the driving unit to rotate around its own axis. The axis of the steering rod 114 extends along the first direction. The grinding belt 130 is rotatably connected to the steering rod 114, and the grinding belt 130 and the shrinking unit are arranged on the driving unit, and the shrinking unit is closer to the center of the plate relative to the steering rod 114, so as to increase the area covered by the grinding belt 130 on the steering rod 114. The driving unit is used to control the steering rod 114 to rotate along its own radial direction. The turning rods 114 in the plurality of adjustment components correspond to the plurality of edges of the plate extending along the first direction one by one, and the grinding belt 130 between two adjacent turning rods 114 can contact the corresponding surface of the plate, so as to grind the plate. The plurality of driving parts can make the corresponding turning rods 114 adjust the size of the rectangle projected by the plurality of turning rods 114 in the first direction according to the size of the plate, thereby having a wider range of uses; and the shrinking part can shorten the distance between the grinding belts 130 on both sides of a turning rod 114, reduce the influence of the size of the turning rod 114 on the edge of the plate, make the grinding belt 130 as close to the edge of the plate as possible, and improve the grinding quality.

[0024] Specifically, the board material of solid wood furniture is generally rectangular, and the number of adjustment mechanisms is set to four, that is, the projections of the four turning rods 114 in the four adjustment mechanisms in the first direction are the four vertices of the rectangle, and the grinding belts 130 are the four sides of the rectangle. In order to reduce the interference of the diameter of the turning rod 114 on the grinding position of the grinding belt 130, the shrinkage part corresponding to each turning rod 114 can make the two adjacent grinding belts 130 on the rectangle have an intersection point that is closer to the edge of the board than the turning rod 114.

[0025] In this embodiment, two driving parts are provided in each adjusting component, each driving part includes a first motor 110, a telescopic rod 111, a second motor 112 and a rotating plate 113, the first motor 110 is fixedly mounted on the frame 100, and the axis of the output shaft of the first motor 110 extends along the first direction, one end of the telescopic rod 111 is fixedly mounted on the output shaft of the first motor 110, the telescopic direction of the telescopic rod 111 is perpendicular to the first direction, the second motor 112 is fixedly mounted on the end of the telescopic rod 111 away from the first motor 110, the output shaft of the second motor 112 is parallel to the output shaft of the first motor 110, and the rotating plate 113 is fixedly mounted on the second motor 112. On the output shaft, both ends of the steering rod 114 are rotatably connected with the rotating plate 113 respectively, and the steering rod 114 is coaxial with the output shaft of the second motor 112. The two rotating plates 113 support one steering rod 114, and the movement of the steering rod 114 is more stable. The extension axis of the telescopic rod 111 intersects with the extension axis of the steering rod 114. Through the rotation of the first motor 110 and the extension and contraction of the telescopic rod 111, the steering rod 114 can move in the horizontal direction and the vertical direction. The cooperation of multiple steering rods 114 enables the grinding belt 130 between the two steering rods 114 to change its position according to the different sizes of the plates, so that the grinding belt 130 can better contact the plates.

[0026] In this embodiment, the shrinking portion includes two guide rods 115, and the two ends of each guide rod 115 are respectively rotatably arranged on two rotating plates 113 around their own axes, and the two guide rods 115 extend along the first direction, and the two guide rods 115 are located on two radial lines of the turning rod 114, and the connecting line distance between the axes of the two guide rods 115 is consistent with twice the thickness of the grinding belt 130. When the grinding belt 130 is wound around the turning rod 114, it passes between the two guide rods 115 and contacts the turning rod 114, and then passes between the two guide rods 115 away from the turning rod 114. The two guide rods 115 on each rotating plate 113 make the grinding belt 130 The vertices of the rectangle formed by the projection in the first direction are far away from the turning rod 114, so that the rectangle surrounded by the grinding belt 130 is smaller than the rectangle surrounded by the four turning rods 114, and the turning rod 114 is not in the rectangle surrounded by the grinding belt 130. The four edges of the plate correspond to the vertices of the rectangle surrounded by the grinding belt 130, respectively, reducing the blind area of ​​the plate and the grinding belt 130, so that the grinding belt 130 can better contact the plate; the second motor 112 drives the rotating plate 113 to rotate, which can adjust the extension direction of the perpendicular midline of the center line of the corresponding two guide rods 115, so that it coincides with the diagonal line corresponding to the plate, so that the grinding belt 130 can adapt to plates of different sizes. When the grinding belt 130 rotates in a cycle, it can drive the corresponding turning rod 114 and guide rod 115 to rotate, reducing the friction between the grinding belt 130 and the turning rod 114 and guide rod 115, and reducing the loss of the grinding belt 130.

[0034] The working principle of a wood sander for producing resin solid wood furniture provided in the above embodiment is: First, the first motor 110 is started through the control panel according to the size of the plate to be polished.
