DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1 A high-precision engraving machine for desks and chairs in this embodiment includes a workbench 1, an installation box 2 is fixed on the upper surface of the workbench 1, a linear module 3 is fixed on the lower surface of the installation box 2, an engraving machine body 4 is slidably connected to the lower surface of the linear module 3, a positioning mechanism 5 for positioning a wooden board is provided on the upper surface of the workbench 1, and filtering mechanisms 6 for filtering dust are provided on the left and right sides of the installation box 2.

[0023] The installation box 2 is in the shape of a rectangular parallelepiped with a hollow interior and a missing front and lower surface. The front of the installation box 2 is hingedly connected to a transparent box door via a door hinge.

[0024] It is understandable that starting the engraving machine body 4 enables it to perform high-precision engraving on the wooden board. When it is necessary to engrave other positions, the position of the engraving machine body 4 can be adjusted by the linear module 3.

[0025] See also Figure 2 In order to position the wooden board, the positioning mechanism 5 in this embodiment includes a bearing platform 501 fixed on the upper surface of the workbench 1, and the left and right ends between the inner top wall and the inner bottom wall of the bearing platform 501 are rotatably connected with threaded rods 502 through bearings. A fixing groove 503 is opened in the middle of the inner bottom wall of the bearing platform 501, and a driving motor 504 is fixed to the inner bottom wall of the fixing groove 503. The output shaft of the driving motor 504 is respectively connected to the two threaded rods 502 through belt transmission, and the outer surface of the threaded rod 502 is threadedly connected with a screw sleeve 505. Place the wooden board on the upper surface of the supporting platform 501, and then start the driving motor 504. The output shaft of the driving motor 504 can rotate to drive the two threaded rods 502 to rotate through two belts. The rotation of the threaded rod 502 causes the screw sleeve 505 threadedly connected on its surface to move. Positioning plates 506 are provided at both ends of the upper surface of the supporting platform 501. A hinged rod 507 is provided between the positioning plate 506 and the side opposite to the screw sleeve 505. The hinged rod 507 is hingedly connected to the positioning plate 506 and the side opposite to the screw sleeve 505 through a hinged seat.

[0026] The left and right side walls of the inner cavity of the support platform 501 are fixed with limit strips on opposite sides, and the two screw sleeves 505 are fixed with limit blocks on opposite sides. The limit blocks are slidably connected with the limit strips.

[0027] In this embodiment, fixed plates are fixed on the left and right ends of the inner top wall of the supporting platform 501, a sliding rod is fixed between the opposite sides of the two fixed plates, a sliding sleeve is fixed on the lower surface of the positioning plate 506, and the sliding sleeve is slidably connected to the outer surface of the sliding rod. The upward movement of the screw sleeve 505 can drive the hinge rod 507 to move through the hinge seat, and the positioning plate 506 can move linearly through the setting of the sliding rod and the sliding sleeve, so that the two positioning plates 506 can move relative to each other, and then the wooden board can be positioned. A guide hole is opened on the upper surface of the supporting platform 501, and the inner diameter of the guide hole is adapted to the outer diameter of the hinge rod 507. The two positioning plates 506 are symmetrically distributed on the left and right ends of the vertical central axis of the supporting platform 501, and the size of the positioning plate 506 is larger than the size of the inner cavity of the guide hole.

[0028] It should be noted that positioning the wood board to be engraved can prevent it from shifting when the engraving machine body 4 is in use, thereby improving the engraving accuracy of the engraving machine body 4 and thus improving the aesthetics of the engraving class chair.

[0029] See also Figures 3 to 4 In order to prevent a large amount of dust from being scattered into the air, the filtering mechanism 6 in this embodiment includes a fixed mesh cover 601 fixed on the left and right sides of the installation box 2, and the inner cavity of the fixed mesh cover 601 is provided with a fan 602. The left and right sides of the installation box 2 are provided with ventilation holes 603, and the inner cavity of the ventilation holes 603 is provided with a filter plate 604. The fan 602 can be started, and the fan 602 can extract the air from the inner cavity of the installation box 2 through the ventilation holes 603. At this time, the dust in the air can be absorbed by the filter plate 604, thereby reducing the emission of dust. The left and right sides of the inner cavity of the installation box 2 are provided with ventilation holes 603. Mounting grooves are provided at the upper and lower ends of the opposite side of the two side walls, and the opposite side of the mounting grooves at the upper and lower ends is hingedly connected with a movable plate 605 through a hinge seat, and springs 606 are fixed to the left and right ends of the opposite side of the movable plates 605 at the upper and lower ends, and plug blocks 607 are fixed to the opposite side of the movable plates 605 at the upper and lower ends and on the rear side of the spring 606. The movable plate 605 is moved toward the side that squeezes the spring 606, so that the angle of the movable plate 605 changes, thereby causing the side away from the spring 606 to rise, so that the plug block 607 can be moved.

[0030] Among them, slots are opened at the upper and lower ends of the filter plate 604, and the size of the inner cavity of the slot is adapted to the size of the plug block 607, so that the plug block 607 can be separated from the slot, the limit of the filter plate 604 can be released, and then the filter plate 604 can be pulled out of the ventilation hole 603 and replaced, so that the filtering effect of the filter plate 604 is better.

[0031] The working principle of the above embodiment is:

[0032] (1) When engraving a wooden board, first place the wooden board on the upper surface of the supporting platform 501, and then start the driving motor 504. The output shaft of the driving motor 504 can rotate to drive the two threaded rods 502 to rotate through two belts. The rotation of the threaded rod 502 causes the screw sleeve 505 threadedly connected to its surface to move. Due to the setting of the limit bar and the limit block, the movement of the screw sleeve 505 can be limited so that it can move in a straight line. The upward movement of the screw sleeve 505 can drive the hinge rod 507 to move through the hinge seat, and the setting of the sliding rod and the sliding sleeve can make the positioning plate 506 move in a straight line, so that the two positioning plates 506 can move relative to each other, thereby positioning the wooden board. Then, the engraving machine body 4 is started to perform high-precision engraving on the wooden board. When it is necessary to engrave other positions, the position of the engraving machine body 4 can be adjusted by the linear module 3.

[0033] (2) When the engraving machine body 4 is engraving, a lot of dust will be generated, so the fan 602 can be started. The fan 602 can draw out the air in the inner cavity of the installation box 2 through the ventilation hole 603. At this time, the dust in the air can be adsorbed by the filter plate 604, thereby reducing the emission of dust; when the filter plate 604 is disassembled and replaced, the movable plate 605 can be moved toward the side of the extrusion spring 606 to change the angle of the movable plate 605, thereby raising the side away from the spring 606, and moving the plug block 607 to separate the plug block 607 from the slot, thereby releasing the limit of the filter plate 604, and then pulling the filter plate 604 out of the ventilation hole 603 for replacement.
