Description

Technical Field

[0001] This utility model relates to the field of wood processing technology, specifically to an automatic dust removal wood sander. Background Technology

[0002] A wood sander is a mechanical device used to sand the surface of wood to make it smooth, clean, or to achieve a specific surface treatment effect. It is an indispensable tool in woodworking. In order to improve environmental protection, some sanders have an automatic dust removal function.

[0003] For example, the patent application number published on the China Patent Network is 202420744181.8, and the patent name is: An automatic dust removal wood sander. It includes a machine body, a processing chamber set on the machine body, an electric lifting cylinder and a polishing structure set in the processing chamber; it also includes: a wood fixing mold set in the processing chamber, a pair of assembly rods set in the port of the wood fixing mold, clamping cylinders connected to the assembly rods on both sides, and clamping rods for fixing the wood on the side of each assembly rod; this utility model uses a power suction pump to provide suction, which can simultaneously suck the dust generated during the polishing of the polishing disc from the dust hood, dust channel and corrugated suction pipe into the barrier filter, effectively avoiding the injury to the surrounding personnel caused by the high temperature debris splashing, and reducing environmental pollution.

[0004] However, existing sanders mainly rely on extraction to pick up wood chips. During the polishing process, the wood chips will be scattered in the surrounding environment. Although they can be extracted, the wood chips will still float and move around near the working environment. Since the wood is mainly fed by manual pushing, operators close to the working environment are prone to inhaling the floating wood chips, causing respiratory damage.

[0005] Therefore, it is necessary to redesign and modify the automatic dust removal wood sander. Utility Model Content

[0006] To address the problems mentioned in the background art, the purpose of this utility model is to provide an automatic dust removal wood sander that has the advantage of replacing manual operation. It solves the problem that existing sanders mainly rely on extraction to pick up wood chips, which are scattered in the surrounding environment during the polishing process. Although they can be extracted, the wood chips still float and move around in the vicinity of the working environment. Since the wood is mainly fed by manual pushing, operators close to the working environment are prone to inhaling floating wood chips, causing respiratory damage.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an automatic dust removal wood sander, including a dust removal box; A grinding wheel assembly is fixedly connected to the top of the dust collection box. An electric vacuum cleaner located on the back of the grinding wheel assembly is connected to the surface of the dust collection box. A transmission roller is installed at the transmission end of the grinding wheel assembly. A sanding belt is sleeved on the surface of the transmission roller. Wood is placed on the top of the sanding belt. Connecting blocks are fixedly connected to both sides of the front of the grinding wheel assembly. A first reciprocating screw is movably connected to the inner side of the connecting block through a bearing. A threaded sleeve is threadedly connected to the surface of the first reciprocating screw. A bracket is fixedly connected to both sides of the threaded sleeve. A pressure plate is movably connected to the side of the bracket away from the threaded sleeve through a pin. The side of the pressure plate away from the bracket extends to the top of the wood and squeezes and fixes the wood to the surface of the sanding belt. A transmission structure is provided on the surface of the threaded sleeve, which can control the squeezing intensity of the pressure plate.

[0008] As a preferred embodiment of this utility model, the transmission structure includes an adjusting screw movably connected to the front end of the screw sleeve via a bearing, a transmission block being threadedly connected to the surface of the adjusting screw, sleeve plates located outside the transmission blocks being fixedly connected to both sides of the bracket, sliding rods located inside the sleeve plates being fixedly connected to both sides of the transmission block, the sliding rods being slidably connected to the sleeve plates, and a rotating wheel being fixedly connected to the front end of the adjusting screw.

[0009] As a preferred embodiment of this invention, both the front end of the transmission roller and the right end of the first reciprocating screw are fixedly connected to a conical wheel, which can control the first reciprocating screw to rotate synchronously when the transmission roller rotates.

[0010] As a preferred embodiment of this utility model, the bottom of the pressure plate is provided with a connecting frame, and the two ends of the connecting frame extend to both sides of the wood.

[0011] As a preferred embodiment of this utility model, the top of the pressure plate is hollowed out, and upright plates are fixedly connected to both sides of the top of the pressure plate. The inner side of the upright plate is movably connected to a second reciprocating screw through a bearing, and the connecting frame is sleeved on the surface of the second reciprocating screw and threadedly connected to the second reciprocating screw.

[0012] In a preferred embodiment of this invention, the rear end of the second reciprocating screw extends through to the rear side of the pressure plate and is fixedly connected to a gear. A toothed plate located at the bottom of the gear is fixedly connected to the surface of the sanding unit, and the toothed plate and the gear mesh with each other.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model connects an electric vacuum cleaner directly to the dust collection box located below the grinding wheel unit and precisely sets it on the back of the grinding wheel unit, enabling direct, efficient, and close-range extraction of wood chips generated at the source of grinding. The pressure plate can replace manual fixation of the wood, allowing the operator to be completely removed from the area where wood chips are generated, thus eliminating the risk of respiratory injury at the source.

[0014] 2. This utility model achieves precise control of the pressure plate angle and pressure by moving the transmission block back and forth through the thread drive and cooperating with the linear guidance of the slide rod inside the sleeve plate. The rotary wheel setting allows the operator to remotely adjust the pressure in a safe area, avoiding contact with dust areas. At the same time, the mechanical adjustment structure is stable and reliable, ensuring that the pressure transmission does not deviate.

[0015] 3. This utility model transmits the power of the transmission roller synchronously to the first reciprocating screw through the meshing of the inclined conical wheel, eliminating the need for an independent drive motor, reducing energy consumption and cost. The mechanical forced synchronization ensures that the moving speed of the pressure plate is strictly matched with the speed of the sanding belt, ensuring uniform feeding of the wood and avoiding uneven surface sanding.

[0016] 4. This utility model uses a connecting frame spanning both sides of the wood to form a U-shaped constraint structure, which effectively prevents the wood from shifting laterally. Its lateral extension design simultaneously prevents wood chips from splashing and escaping from both sides of the workpiece, forming a three-sided enclosed space with the upper pressure plate, thus improving the dust removal coverage.

[0017] 5. This utility model utilizes the threaded engagement between the second reciprocating screw and the connecting frame, and uses the rotation of the second reciprocating screw to drive the connecting frame to move laterally, so that the connecting frame can drive the wood to move horizontally, thereby further improving the polishing effect.

[0018] 6. This utility model converts the horizontal reciprocating motion of the pressure plate into the rotational motion of the second reciprocating screw by meshing the fixed toothed plate and the gear, which can save the operation steps of setting up additional drive equipment and reduce energy consumption.

[0021] 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.

[0022] like Figures 1 to 4 As shown, the present invention provides an automatic dust removal wood sander, which includes a dust removal box 1; A grinding wheel assembly 2 is fixedly connected to the top of the dust collection box 1. An electric vacuum cleaner 3 located on the back of the grinding wheel assembly 2 is connected to the surface of the dust collection box 1. A transmission roller 4 is installed at the transmission end of the grinding wheel assembly 2. A sanding belt 5 is sleeved on the surface of the transmission roller 4. Wood 6 is placed on the top of the sanding belt 5. Connecting blocks 7 are fixedly connected to both sides of the front of the grinding wheel assembly 2. A first reciprocating screw 8 is movably connected to the inner side of the connecting block 7 through a bearing. A threaded sleeve 9 is threadedly connected to the surface of the first reciprocating screw 8. A bracket 10 is fixedly connected to both sides of the threaded sleeve 9. A pressure plate 11 is movably connected to the side of the bracket 10 away from the threaded sleeve 9 through a pin. The side of the pressure plate 11 away from the bracket 10 extends to the top of the wood 6 and presses and fixes the wood 6 to the surface of the sanding belt 5. A transmission structure is provided on the surface of the threaded sleeve 9. The transmission structure can control the pressing intensity of the pressure plate 11.

[0023] refer to Figure 4 The transmission structure includes an adjusting screw 12 movably connected to the front end of the screw sleeve 9 via a bearing. A transmission block 13 is threadedly connected to the surface of the adjusting screw 12. Sleeve plates 14 located outside the transmission block 13 are fixedly connected to both sides of the bracket 10. Slide rods 15 located inside the sleeve plate 14 are fixedly connected to both sides of the transmission block 13. The slide rods 15 are slidably connected to the sleeve plate 14. A rotating wheel 16 is fixedly connected to the front end of the adjusting screw 12.

[0024] As a technical optimization of this utility model, the threaded drive transmission block 13 moves back and forth, and with the linear guidance of the slide rod 15 inside the sleeve plate 14, the angle and pressure of the pressure plate 11 can be precisely controlled. The rotating wheel 16 allows the operator to remotely adjust the pressure in a safe area, avoiding contact with dust. At the same time, the mechanical adjustment structure is stable and reliable, ensuring that the pressure transmission does not deviate.

[0025] refer to Figure 2 Both the front end of the transmission roller 4 and the right end of the first reciprocating screw 8 are fixedly connected to a conical wheel 17, which can control the first reciprocating screw 8 to rotate synchronously when the transmission roller 4 rotates.

[0026] As a technical optimization of this utility model, the power of the transmission roller 4 is synchronously transmitted to the first reciprocating screw 8 through the engagement of the inclined conical wheel 17, eliminating the need for an independent drive motor, reducing energy consumption and cost. The mechanical forced synchronization ensures that the moving speed of the pressure plate 11 is strictly matched with the linear speed of the sanding belt 5, ensuring that the wood 6 is fed at a uniform speed and avoiding uneven surface sanding.

[0027] refer to Figure 3 The bottom of the pressure plate 11 is provided with a connecting frame 18, and the two ends of the connecting frame 18 extend to both sides of the wood 6.

[0028] As a technical optimization of this utility model, the connecting frame 18 is straddling both sides of the wood 6 to form a U-shaped constraint structure, which effectively prevents the wood 6 from shifting laterally. Its lateral extension design simultaneously blocks wood chips from splashing and escaping from both sides of the workpiece, forming a three-sided enclosed space with the upper pressure plate 11, thereby improving the dust removal coverage.

[0029] refer to Figure 3 The top of the pressure plate 11 is hollowed out. Both sides of the top of the pressure plate 11 are fixedly connected to the vertical plate 19. The inner side of the vertical plate 19 is movably connected to the second reciprocating screw 20 through the bearing. The connecting frame 18 is sleeved on the surface of the second reciprocating screw 20 and threadedly connected to the second reciprocating screw 20.

[0030] As a technical optimization of this utility model, the second reciprocating screw 20 is threadedly engaged with the connecting frame 18, and the second reciprocating screw 20 is used to drive the connecting frame 18 to move laterally, so that the connecting frame 18 can drive the wood 6 to move horizontally, thereby further improving the polishing effect.

[0031] refer to Figure 3 The rear end of the second reciprocating screw 20 extends to the rear side of the pressure plate 11 and is fixedly connected to a gear 21. The surface of the sanding unit is fixedly connected to a toothed plate 22 located at the bottom of the gear 21, and the toothed plate 22 and the gear 21 mesh with each other.

[0032] As a technical optimization of this utility model, the horizontal reciprocating motion of the pressure plate 11 is converted into the rotational motion of the second reciprocating screw 20 by the meshing of the fixed tooth plate 22 and the gear 21, which can save the operation steps of setting up additional drive equipment and reduce energy consumption.

[0033] The working principle and usage process of this utility model: The operator places the wood 6 to be sanded on the top of the sanding belt 5. The wood 6 placed on the sanding belt 5 will be pressed down and fixed on the surface of the sanding belt 5 by the connecting frame 18 on the surface of the pressure plate 11. When the wood 6 is installed, the sanding wheel unit 2 starts to work and drives the transmission roller 4 to rotate. The transmission roller 4 drives the abrasive belt 5, which is sleeved on its surface, to rotate in a circular motion. At the same time, the transmission roller 4 drives the first reciprocating screw 8 to rotate synchronously using the inclined conical wheel 17. The rotation of the first reciprocating screw 8 drives the screw sleeve 9 to make a reciprocating linear motion on its surface. Since the bracket 10 is fixed on the screw sleeve 9, the bracket 10 also moves left and right with the screw sleeve 9. This causes the pressure plate 11, which is movably connected to the bracket 10, to move left and right above the wood 6. When the pressure plate 11 moves, the gear 21 fixed at the rear end of the second reciprocating screw 20 will mesh with the rack fixed on the surface of the grinding wheel unit 2. This meshing action will drive the second reciprocating screw 20 to rotate. The rotation of the second reciprocating screw 20 drives the connecting frame 18 to move back and forth relative to the main body of the pressure plate 11 through the thread. In this way, the function of lateral displacement can be added during the horizontal movement of the wood 6, which further improves the polishing effect.

[0034] In summary, this automatic dust-removing wood sander directly connects the electric vacuum cleaner 3 to the dust collection box 1 located below the sander unit 2 and precisely positions it on the back of the sander unit 2. This enables direct, efficient, and close-range extraction of wood chips generated at the source of sanding. The pressure plate 11 can replace manual labor to fix the wood, allowing the operator to completely escape from the area where wood chips are generated, thus eliminating the risk of respiratory injury at the source.
