[0042] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0043] Example 1, as Figures 1 to 8 As shown, a furniture manufacturing sanding device includes a worktable 3 equipped with a support frame 1 and a sanding assembly 2, and further includes a translation slide rail 4, a self-locking slide rail 5, a first protective cover 6, a second protective cover 7, a clamping element 8, a limiting support block 9, a support plate 10, and a vacuum cleaner 11. The support rods at both ends of the bottom of the support plate 10 are bolted to the top surface of the support frame 1. A translation slide rail 4 is horizontally embedded on one side of the support frame 1 on the worktable 3. A seat plate 12 is longitudinally arranged on the slider in the translation slide rail 4, and the seat plate 12 has... A hand-cranked locking limit screw 13 is bolted on; two symmetrically arranged clamping parts 8 are sleeved on the screw of the hand-cranked locking limit screw 13; a self-locking slide rail 5 is longitudinally embedded on the workbench 3 between the support frame 1 and the translation slide rail 4; a limit support block 9 is bolted on the self-locking slide rail 5; a first protective cover 6 is provided between the support frame 1 and the self-locking slide rail 5, and a second protective cover 7 is provided on the other side of the support frame 1; the second protective cover 7 is connected to a vacuum cleaner 11 on the bottom surface of the workbench 3 through a vacuum pipe;

[0044] Furthermore, according to Figure 1 Combination Figure 3 It is known that the self-locking slide rail 5 is equipped with two self-locking sliders, and a limiting support block 9 is installed on each of the two self-locking sliders by bolts. The limiting support blocks on the two self-locking slide rails are symmetrically arranged and are used to adaptively adjust the distance between the two limiting support blocks according to the width of the wood board, so as to support and guide the wood board and further prevent the wood board from shifting position during the sanding process.

[0045] Furthermore, such as Figure 2 As shown, a vertical push rod 14 is bolted to the left side of the clamping member 8 on the seat plate 12, which is used to push the seat plate to move linearly; a control box 15 is bolted to the top of the vertical push rod 14, which is used to control the start and stop of the grinding component and the vacuum cleaner; the vacuum cleaner 11 is electrically connected to the control box 15.

[0046] In use, first, insert one end of the wooden board from the left end of the workbench through the rectangular slot with the brush to the right, and into the first protective cover. Next, the operator turns the hand crank to rotate the screw in the hand-cranked locking limit screw, thereby moving the clamping parts to both sides of the wooden board. While gently lifting the wooden board, continue turning the hand crank until the wooden board can be placed on the lower clamping part of the clamping part. Then, turn the handle on the clamping part to move the upper clamping part down until it presses the wooden board firmly. After that, push the limit support block until it contacts the side and bottom of the wooden board, limiting, guiding, and supporting the wooden board. Then, turn the handle on the support plate to lower the sanding assembly to the appropriate position. Finally, the operator controls the motor in the sanding assembly and the vacuum cleaner to start via the controller, and then pushes the vertical push rod along the translation rail to move the wooden board forward for sanding. The operation is convenient, effectively fixing the wooden board and preventing displacement during sanding. It can also absorb and clean the sawdust and dust generated during sanding. It is simple and practical to operate.

[0047] Example 2, as a preferred embodiment of Example 1 above, is as follows: Figure 2 As shown, the support frame 1 is a stainless steel support frame, which is formed by welding together a top plate 101, a bottom plate 102 and two vertical plates 103; the bottom plate 102 is a cross-shaped bottom plate, which is bolted to the middle of the workbench 3.

[0048] like Figure 2 As shown, the sanding assembly 2 consists of a motor 201, a sanding head 202, and a coupling. The motor shaft of the motor 201 passes through the top plate 102 from top to bottom and is connected to a connecting shaft via the coupling. The other end of the connecting shaft is connected to the sanding head 202 via a rotating shaft fixing seat. The motor 201 is connected to the control box 15. The diameter of the sanding head 15 is slightly smaller than the diameter of the horizontal plate in the bottom plate 102 to facilitate one-time sanding and polishing of the wood surface.

[0049] like Figure 1 , Figure 2 and Figure 3 As shown, a sliding sleeve is welded to one side of the housing of the motor 201 in the grinding assembly 2, and an internally threaded sliding sleeve is welded to the other side symmetrically; a sliding rod is inserted into the sliding sleeve, the bottom end of the sliding rod is threaded to the top surface of the support frame 1, and the top end of the sliding rod is inserted into the bottom surface of the support plate 10; a first threaded rod is inserted into the internally threaded sliding sleeve, the bottom end of the first threaded rod is connected to the top surface of the support frame 1 through a bearing seat, and the top end of the first threaded rod is connected to the first crank on the top surface of the support plate 10 through a coupling;

[0050] Utilizing the principle of lead screw transmission, rotating the first crank handle drives the threaded rod to rotate, which in turn causes the internal threaded sleeve to rise or fall, thereby causing the motor to lift and lower, and driving the connecting shaft to extend and retract in the vertical direction. This allows the height of the grinding head to be adjusted according to the thickness of the wood board, making it convenient and practical.

[0051] Example 3, as a preferred embodiment of Example 1 above, is as follows: Figure 2 As shown, the screw in the hand-cranked locking limit screw 13 is a positive and negative thread screw. By rotating the hand crank, the screw is driven to rotate, and the rotation of the screw drives the ball nut to slide on the screw, thereby realizing the left and right opening and closing between the two clamping parts set on the screw.

[0052] like Figure 2 As shown, the clamping member 8 includes an upper clamping plate 801 and a lower clamping plate 802. A second threaded rod equipped with a nut seat is inserted into the middle of the rear side of the upper clamping plate 801. A sliding rod is symmetrically inserted into the upper clamping plate 801 on the left and right sides of the second threaded rod. A limit block is integrally formed at the top of the sliding rod, and the bottom of the sliding rod is connected to the rear side of the lower clamping plate through a fixed seat. A second crank is provided at the top of the second threaded rod through a pin, and the bottom of the second threaded rod is connected to the rear side of the lower clamping plate 802 through a bearing seat.

[0053] Utilizing the screw drive principle, rotating the second crank handle drives the second threaded rod to rotate, which in turn causes the nut seat to rise or fall, thereby raising or lowering the upper clamping plate. This allows for adaptive adjustment of the clamping components according to the thickness of the wooden board. The bottom of the lower clamping plate is equipped with movable rollers, which facilitate movement and provide support.

[0054] It should be noted that, for example Figure 2 As shown, during installation, the nut seat is bolted to the rear side of the lower clamping plate 802; rubber anti-slip pads are adhered to the bottom surface of the upper clamping plate 801 and the upper surface of the lower clamping plate 802 to prevent the wooden board from sliding and to avoid damage to the wooden board due to excessive clamping force; the clamping upper surface of the lower clamping plate 802 is on the same horizontal plane as the base plate; in addition, a ball nut should be embedded (or bolted) in the lower clamping plate to facilitate the interaction with the lead screw in the hand-cranked locking limit screw 13 to achieve transmission; the hand-cranked locking limit screw 13 is an existing structure, which consists of a hand crank, lead screw, ball nut, fixed seat, locking block and locking handle, etc., and the specific settings will not be described in detail here.

[0055] Example 4, as a preferred embodiment of Example 1 above, is as follows: Figure 2As shown, several rotating rollers 16 are evenly distributed longitudinally on the other side of the support frame 1 on the workbench 3. They are used to support the sanded part of the wooden board workpiece and guide the wooden board workpiece to facilitate its movement. Support blocks are provided at both ends of the rotating rollers 16 through rotating bearing seats. The support blocks are installed on the workbench 3 by bolts.

[0056] In this case, the top surface of the rotating roller 16 should be on the same horizontal plane as the base plate 102 so that the wooden board can maintain parallel movement.

[0057] Example 5, as a preferred embodiment of Example 1 above, such as Figure 1 , Figure 2 and Figure 3 As shown, a mounting bracket 17 is bolted to the bottom surface of the workbench 3; the vacuum cleaner 11 is bolted to the base in the mounting bracket 17; as Figure 1 and Figure 6 As shown, the bottom front side of the dust collection chamber in the vacuum cleaner 11 is integrally formed with a discharge funnel, and a nut is threadedly connected to the outer wall of the discharge port at the bottom end of the discharge funnel; a dust collection bag 18 is provided on the bottom surface of the discharge funnel for collecting dust such as wood chips.

[0058] Example 6, as a preferred embodiment of Example 1 above, such as Figure 1 , Figure 3 and Figure 4 As shown, both the first protective cover 6 and the second protective cover 7 have rectangular slots for easy passage of wooden boards; the bottom edge of the rectangular slot is slightly lower than the upper surface of the bottom plate 102 in the support frame 1, and the top edge of the rectangular slot is much higher than the upper surface of the bottom plate 102 in the support frame 1, to facilitate the passage of wood of different thicknesses; as shown Figure 1 , Figure 3 and Figure 5 As shown, brushes 19 are attached to the four side walls of the rectangular through groove to prevent sawdust and other materials from flying out of the protective cover, and at the same time to preliminarily clean the sawdust remaining on the wood surface.

[0059] like Figure 1 As shown, a pipe interface is provided at the through hole position on one side plate of the second protective cover via bolts for easy installation of the vacuum hose; as Figure 3 As shown, a door panel is provided on the other side of the second protective cover via a snap fastener, which is used to facilitate the cleaning of residual wood chips inside the protective cover; both the first and second protective covers are made of transparent plexiglass, or PC or PETG materials, which have stable molecular structures and do not easily adsorb dust, wood chips, etc., making it convenient for staff to observe the sanding process.

[0060] It should be noted that the width of the rectangular through groove should be slightly smaller than the width of the protective cover; the length and height of the first protective cover are the same as those of the second protective cover, and the width of the second protective cover is greater than that of the first protective cover, so as to accommodate a longer sliding rail and allow the wooden board to move forward a greater distance; it should be noted that there is a sealing ring on the door panel, and there is also a sealing ring between the pipe interface and the second protective cover, which serves to ensure a tight connection and prevent wood chips from flying out, and avoid damage to the protective cover caused by excessive installation force;

[0061] During installation, both the first and second protective covers are bolted to the support frame, and the bottoms of both protective covers are bolted to the workbench. Rubber sealing strips are installed between the protective covers and the support frame and workbench to ensure a tight connection between the protective covers and the support frame and workbench.

[0062] Example 7, as a preferred embodiment of Example 1 above, is as follows: Figure 1 , Figure 3 and Figure 7 , Figure 8 As shown, the limiting support block 9 is L-shaped; a first roller 901 is provided in the high side through groove of the limiting support block 9 through a rotating shaft, which is used to contact the side of the wooden board to prevent the wooden board from shifting, and at the same time facilitates the forward movement of the wooden board, thus playing a guiding role; a second roller 902 is evenly distributed in the bottom side groove of the limiting support block 9, which is used to contact the bottom surface of the wooden board, can support the wooden board, and at the same time facilitates the forward movement of the wooden board, thus playing a guiding role;

[0063] Among these, such as Figure 8 As shown, the diameter of the first roller 901 is slightly larger than the length of the high side through groove of the limiting support block, so that the first roller can contact the side of the wooden board; in addition, the top surface of the second roller 902 is on the same horizontal plane as the upper surface of the bottom plate.

[0064] Obviously, the above-described embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
