Description

Technical Field

[0001] The present invention relates to the technical field of wood processing, and particularly to a wood grinding machine for the production of resin solid wood furniture. Background Art

[0002] Solid wood furniture refers to furniture made of solid wood. Since a large number of burrs will be generated during the cutting of the board, 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 its surface, and then assemble and paint the ground board, so that the overall feel and flatness of the solid wood furniture are better.

[0003] However, common board grinding machines can only grind one side of the board during use, with low efficiency. Some grinding machines, in order to improve the grinding efficiency, add grinding rollers to grind multiple sides of the board simultaneously. As the use time of the grinding rollers increases, the wear degrees on the surfaces of multiple grinding rollers are prone to differences, resulting in uneven grinding degrees of multiple grinding rollers on the board, and ultimately affecting the grinding quality of the board. Summary of the Invention

[0029] Such as Figures 1 to 8As shown in the figure, a wood grinding machine for resin solid wood furniture production provided by an embodiment of the present invention includes a frame 100, a conveying mechanism, a bracket, a power mechanism, and a grinding belt 130. The frame 100 is fixedly arranged. The conveying mechanism is arranged on the frame 100 and is used to convey the board along a first direction, and the first direction is parallel to the horizontal direction. The bracket is arranged on the frame 100, and the board is arranged in the bracket. The power mechanism includes a power component, a first cross bar 101, and a second cross bar 102. The power component is arranged on the frame 100, the first cross bar 101 and the second cross bar 102 are arranged on the power component. The first cross bar 101 and the second cross bar 102 are respectively located on both sides of the bracket in the first direction. The first cross bar 101 and the second cross bar 102 both extend along a second direction, and the second direction is the horizontal direction and is perpendicular to the first direction. The grinding belt 130 is sequentially wound around the first cross bar 101 and the second cross bar 102. The grinding belt 130 is divided into two side edges between the first cross bar 101 and the second cross bar 102. One of the side edges is wound around the bracket in a positive spiral, and the other side edge is wound around the bracket in a reverse spiral. The spiral axis of the grinding belt 130 wound around the bracket extends along the first direction. Abrasives are provided on both surfaces of the grinding belt 130. The grinding belt 130 is used to grind the board in the bracket. The power component can drive the grinding belt 130 to rotate cyclically 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.

[0030] By arranging the grinding belt 130 on the bracket and using the flexible characteristic of the grinding belt 130 to wind around the bracket, multiple surfaces of the board can be ground. Through the cooperative arrangement of the first cross bar 101, the second cross bar 102, and the grinding belt 130, the grinding belt 130 rotates cyclically on the bracket, improving the uniformity of grinding the multiple surfaces of the board by the grinding belt 130. By arranging the grinding belt 130 in a bidirectional spiral on the bracket, the grinding belt 130 has two opposite rotation directions on the bracket, enabling the surface of the board to be ground alternately, reducing the residual traces in a single grinding direction on the surface of the board, and improving the grinding quality of the surface of the board.

[0031] In this embodiment, the bracket includes a plurality of adjusting components. Each adjusting component corresponds to an edge of the plate extending in the first direction. Each adjusting component includes a driving part, a steering rod 114, and a edge-reducing part. The driving part is arranged on the frame 100. The steering rod 114 is rotatably arranged on the driving part around its own axis. The axis of the steering rod 114 extends in the first direction. The grinding belt 130 is rotatably connected to the steering rod 114, and the grinding belt 130 and the edge-reducing part are arranged on the driving part. The edge-reducing part is closer to the center of the plate than the steering rod 114, and is used to increase the area of the grinding belt 130 wrapped on the steering rod 114. The driving part is used to control the steering rod 114 to move in its own radial direction. The steering rods 114 in the plurality of adjusting components correspond one by one to the edges of the plate extending in the first direction. The grinding belt 130 between two adjacent steering rods 114 can contact the corresponding surface of the plate, so as to grind the plate. The plurality of driving parts can enable the corresponding steering rods 114 to adjust the size of the rectangle formed by the projections of the plurality of steering rods 114 in the first direction according to the size of the plate, so that the use range is wider; and the edge-reducing part can shorten the distance between the grinding belts 130 on both sides of one steering rod 114, reduce the influence of the size of the steering rod 114 on the edge of the plate, make the grinding belt 130 as close as possible to the edge of the plate, and improve the grinding quality.

[0032] Specifically, the plates of solid wood furniture are generally rectangular. The number of adjusting mechanisms is set to four, that is, the projections of the four steering rods 114 in the four adjusting mechanisms in the first direction are the four vertices of a rectangle, and the grinding belt 130 is the four sides of the rectangle. To reduce the interference of the diameter of the steering rod 114 on the grinding position of the grinding belt 130, the edge-reducing part corresponding to each steering rod 114 can create an intersection point of two adjacent grinding belts 130 on the rectangle that is closer to the edge of the plate than the steering rod 114.

[0033] In this embodiment, there are two driving parts 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 installed 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 installed on the output shaft of the first motor 110, and the telescopic direction of the telescopic rod 111 is perpendicular to the first direction. The second motor 112 is fixedly installed at 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. The rotating plate 113 is fixedly installed on the output shaft of the second motor 112. Both ends of the steering rod 114 are rotatably connected to the rotating plate 113, and the steering rod 114 is coaxial with the output shaft of the second motor 112. 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. By rotating the first motor 110 and telescoping the telescopic rod 111, the steering rod 114 can move in the horizontal and vertical directions. 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 plates of different sizes, so that the grinding belt 130 can better contact the plates.

[0034] In this embodiment, the edge shrinking part includes two guide rods 115. Both ends of each guide rod 115 are rotatably arranged on the two rotating plates 113 around their respective axes, and the two guide rods 115 extend along the first direction. The two guide rods 115 are located on two radial lines of the steering rod 114, and the distance between the axes of the two guide rods 115 is the same as twice the thickness of the grinding belt 130. When the grinding belt 130 is wound around the steering rod 114, it passes between the two guide rods 115 to contact the steering rod 114, and then passes between the two guide rods 115 to move away from the steering rod 114. The two guide rods 115 on each rotating plate 113 make the vertices of the rectangle formed by the projection of the grinding belt 130 in the first direction away from the steering rod 114, so that the rectangle formed by the grinding belt 130 is smaller than the rectangle formed by the four steering rods 114. The steering rod 114 is not within the rectangle formed by the grinding belt 130. The four edges of the plate respectively correspond to the vertices of the rectangle formed by the grinding belt 130, reducing the blind area of contact between the plate and the grinding belt 130, so that the grinding belt 130 can better contact the plate; The rotation of the second motor 112 drives the rotating plate 113 to rotate, which can adjust the extension direction of the perpendicular bisector of the center line connecting the two corresponding guide rods 115 to coincide 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 steering rod 114 and guide rod 115 to rotate, reducing the friction between the grinding belt 130 and the steering rod 114 and guide rod 115, and reducing the loss of the grinding belt 130.

[0035] In this embodiment, a top plate 120 is provided on the frame 100. The top plate 120 is located above the conveying mechanism, the power mechanism, the bracket and the grinding belt 130. The conveying mechanism includes a plurality of upper guide rollers 121 and a plurality of lower guide rollers 122. The plurality of upper guide rollers 121 are slidably arranged on the top plate 120 in the vertical direction, and the plurality of upper guide rollers 121 are arranged in the first direction on the top plate 120. The plurality of lower guide rollers 122 are slidably arranged on the frame 100 in the vertical direction, and the plurality of lower guide rollers 122 are arranged in the first direction on the frame 100. The plurality of upper guide rollers 121 and the plurality of lower guide rollers 122 are located in the same vertical plane. The axes of each upper guide roller 121 and each lower guide roller 122 extend along the second direction. A plurality of telescopic members are provided on the top plate 120 and the frame 100. The telescopic member can be a hydraulic cylinder or an electric push rod. A micro motor is provided on the telescopic member. The plurality of telescopic members on the top plate 120 are rotatably connected to the plurality of upper guide rollers 121 one by one. The micro motor on the telescopic member corresponding to the upper guide roller 121 is fixedly connected to the upper guide roller 121. The micro motor can drive the corresponding upper guide roller 121 to rotate. The plurality of telescopic members on the frame 100 are rotatably connected to the plurality of lower guide rollers 122 one by one. The micro motor on the telescopic member corresponding to the lower guide roller 122 is fixedly connected to the lower guide roller 122. The micro motor can drive the corresponding lower guide roller 122 to rotate. Place the plate between the upper guide roller 121 and the lower guide roller 122. The rotated upper guide roller 121 and lower guide roller 122 can drive the plate to move in the first direction.

[0036] In this embodiment, the lengths of the upper guide roller 121 and the lower guide roller 122 in the second direction are less than the length of the plate in the second direction; the grinding belt 130 wound around the bracket will not contact the upper guide roller 121 and the lower guide roller 122, avoiding the occurrence of movement interference.

[0037] In this embodiment, the first cross bar 101 is located above the bracket, and the second cross bar 102 is located below the bracket. The grinding belt 130 located on the bracket has an intersecting part in the projection on the horizontal plane. The grinding belts 130 between two steering rods 114 on the same horizontal plane intersect, and the number of intersecting parts depends on the number of turns of the grinding belt 130 wound around the bracket. The conveying mechanism further includes a separating part for separating the intersecting grinding belts 130 on the bracket. The separating part includes a plurality of first support rods 123 and a plurality of second support rods 124. The number of first support rods 123 is the same as the number of intersecting parts of the grinding belt 130 between the two upper steering rods 114, and the number of second support rods 124 is the same as the number of intersecting parts of the grinding belt 130 between the two lower steering rods 114. Both the first support rod 123 and the second support rod 124 are U-shaped. The first support rod 123 is located above the bracket. Each first support rod 123 includes two first longitudinal rods and a first connecting rod. The two first longitudinal rods are fixedly installed on the top plate 120, and the two first longitudinal rods are arranged along the first direction. The first connecting rod is arranged between the two first longitudinal rods, and both ends of the first connecting rod are rotatably connected to the two first longitudinal rods. Let the plane where the two upper steering rods 114 are located be the first plane. The first connecting rod is located above the first plane and between the two intersecting grinding belts 130 between the two upper steering rods 114, so as to prevent friction and wear between the intersecting grinding belts 130. The plurality of second support rods 124 are arranged along the first direction.

[0038] The second support rod 124 is located below the bracket. Each second support rod 124 includes two second longitudinal rods and a second connecting rod. The two second longitudinal rods are fixedly installed on the frame 100, and the two second longitudinal rods are arranged along the second direction. The second connecting rod is arranged between the two second longitudinal rods, and both ends of the second connecting rod are rotatably connected to the two second longitudinal rods. Let the plane where the two lower steering rods 114 are located be the second plane. The second connecting rod is located below the second plane and between the two intersecting grinding belts 130 between the two lower steering rods 114.

[0039] In this embodiment, a control panel is provided on the frame 100, and the control panel is used to control the start and stop of the conveying mechanism, the power mechanism, the grinding belt 130 and the driving part respectively.

[0040] In this embodiment, the grinding belts 130 on the first cross bar 101 and the second cross bar 102 are respectively located at the centers of the two steering rods 114 on both sides in the axial directions of the corresponding first cross bar 101 and the second cross bar 102. The spiral angles of the grinding belts 130 wound around the bracket are the same, and the grinding belts 130 are in a relatively stable state during the grinding process.

[0041] In this embodiment, the power assembly includes a first hydraulic rod 103, a third motor 104, a second hydraulic rod 105, a push plate 106, and a fourth motor 107. One end of the first hydraulic rod 103 is fixedly installed on the frame 100, and the first hydraulic rod 103 expands and contracts in the vertical direction. The third motor 104 is fixedly installed at the end of the first hydraulic rod 103 away from the frame 100, and the output shaft of the third motor 104 is connected to the first crossbar 101. There are two first hydraulic rods 103 and two third motors 104, and the two first hydraulic rods 103 and the two third motors 104 are respectively located on both sides of the first crossbar 101 in the second direction. The two third motors 104 rotate together to drive the first crossbar 101 to rotate, which can better support the first crossbar 101. One end of the second hydraulic rod 105 is fixedly installed on the frame 100, and the second hydraulic rod 105 expands and contracts in the first direction. The push plate 106 is fixedly installed at the end of the second hydraulic rod 105 away from the frame 100. The fourth motor 107 is fixedly installed on the push plate 106, and the output shaft of the fourth motor 107 is connected to the second crossbar 102. There are two second hydraulic rods 105 and two fourth motors 107, and the two second hydraulic rods 105 and the two fourth motors 107 are respectively located on both sides of the second crossbar 102 in the second direction. The two fourth motors 107 rotate together to drive the second crossbar 102 to rotate. When multiple steering rods 114 approach or move away from each other to adapt to the size of the board, the amount of the grinding belt 130 wound around the bracket changes. The first crossbar 101 moves adaptively under the action of the first hydraulic rod 103, and the second crossbar 102 moves adaptively under the action of the second hydraulic rod 105, so that the grinding belt 130 is in a tensioned state.

[0042] The working principle of a wood grinding machine for resin solid wood furniture production provided by the above embodiment is as follows:

[0043] First, start the first motor 110 through the control panel according to the size of the board to be ground. The first motor 110 drives the corresponding telescopic rod 111 to rotate. Each telescopic rod 111 drives the corresponding steering rod 114 to rotate through the corresponding second motor 112 and the rotating plate 113. Then, start the four second motors 112 respectively. Taking one of them as an example, the second motor 112 drives the rotating plate 113 to rotate. The rotating plate 113 rotates to drive the two guide rods 115 to rotate. The guide rods 115 rotate to drive the grinding belt 130 at the contact position with them to move until the grinding belt 130 between the two mutually approaching guide rods 115 on the adjacent rotating plates 113 is parallel to the corresponding surface of the board.

[0044] Next, start the telescopic rod 111. The telescopic rod 111 drives the corresponding steering rod 114 to move through the corresponding first motor 110 and the rotating plate 113, so that the grinding belt 130 can be in contact with the surface of the corresponding plate at the same time. The telescopic member controls the movement of the corresponding upper guide roller 121 and the lower guide roller 122, so that the plate can be in full contact with the grinding belt 130 between the upper guide roller 121 and the lower guide roller 122. Then, start the micro motor, the third motor 104 and the fourth motor 107. The micro motor drives the corresponding upper guide roller 121 and the lower guide roller 122 to rotate, driving the plate to move into the grinding area along the first direction. At the same time, the third motor 104 drives the first cross bar 101 to rotate, and the fourth motor 107 drives the second cross bar 102 to rotate. The first cross bar 101 and the second cross bar 102 drive the grinding belt 130 to rotate to grind the plate.

[0045] During the adjustment process of each component in the adjustment assembly, the first hydraulic rod 103 drives the first cross bar 101 to move in the vertical direction through the third motor 104, and the second hydraulic rod 105 drives the fourth motor 107 to move in the first direction through the push plate 106, so that the grinding belt 130 is always tightened to provide a better grinding effect.

[0046] The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0047] The above-described embodiments merely represent several implementation manners of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can be made, and these all belong to the protection scope of the present invention.
