Description

Technical Field

[0001] This utility model relates to the field of sanding machine technology, and in particular to a dust-free woodworking sanding machine. Background Technology

[0002] A woodworking sander is a type of woodworking machine tool that uses sanding belts or sandpaper to sand the surface of wooden workpieces in order to obtain a surface with an ideal smoothness. Woodworking sanders are divided into three types: roller type, belt type, and disc type.

[0003] Existing sanders generate a lot of dust during operation, making the working environment very harsh. Moreover, conventional sanders only have one sanding belt for processing, resulting in low production efficiency and difficulty in meeting production and processing needs, leaving room for improvement.

[0004] Therefore, we propose a dust-free wood sander to solve the problems in the background technology. Utility Model Content

[0029] Reference Figure 1-4A dust-free wood sander includes a base plate 1, a sanding mechanism, a wooden board 8, and a control panel 14.

[0030] A dustproof box 2 is provided on the base plate 1. Two sanding mechanisms are provided inside the dustproof box 2. The two sanding mechanisms are symmetrical to each other. The same wooden board 8 is provided between the two sanding mechanisms. A control panel 14 is provided on the dustproof box 2. Both sanding mechanisms are connected to the control panel 14.

[0031] The sanding mechanism includes cylinder 3, U-shaped plate 4, transmission roller 5, sanding belt 6, and motor 7. Two cylinders 3 are fixedly installed inside the dust box 2, and the two cylinders 3 are symmetrical to each other. A U-shaped plate 4 is fixedly installed at one end of each cylinder 3. Two transmission rollers 5 are rotatably connected to the U-shaped plate 4. The same sanding belt 6 is connected to the two transmission rollers 5. The sanding belt 6 is in contact with the wooden board 8. Through the coordinated design of the dust box 2, sanding mechanism, baffle 13, threaded rod 12, motor 11, and industrial vacuum cleaner 9, it is possible not only to achieve the effect of sanding both sides of the wooden board 8 at the same time, but also to achieve the effect of automatically adjusting the sanding position of the wooden board 8, and to automatically suck up and collect the dust in the dust box 2.

[0032] In this method, one end of one of the two drive rollers 5 passes through the dustproof box 2. A movable plate 17 is slidably connected to one side of the dustproof box 2. A motor 7 is fixedly installed on the movable plate 17. The output end of the motor 7 is connected to one end of the drive roller 5. Through the drive of the two cylinders 3 and the motor 7, as well as the transmission of the two U-shaped plates 4 and the four drive rollers 5, the two sanding belts 6 contact the two sides of the wooden board 8 respectively and sand the wooden board 8 at the same time. The motor 7 is connected to the control panel 14, and the control panel 14 controls and drives the motor 7.

[0033] In this method, an industrial vacuum cleaner 9 is provided on the base plate 1. One end of the industrial vacuum cleaner 9 is sealed and connected to a suction pipe. The other end of the suction pipe is sealed and connected to the dustproof box 2. Through the driving of the industrial vacuum cleaner 9 and the cooperation of the suction pipe, the dust in the dustproof box 2 can be sucked and collected, thereby further improving the dustproof effect.

[0034] In this method, a guide plate 18 is fixedly sleeved on one of the two cylinders 3. The guide plate 18 corresponds to the suction pipe. The industrial vacuum cleaner 9 is connected to the control panel 14. At the same time, the guide plate 18 facilitates the collection of dust at the position corresponding to the suction pipe, thereby facilitating the industrial vacuum cleaner 9 to suck up the dust.

[0035] In this method, a fixing plate 10 is fixedly connected to the base plate 1, and a second motor 11 is fixedly installed on the fixing plate 10. A threaded rod 12 is fixedly connected to the output end of the second motor 11, and a baffle 13 is threadedly connected to the threaded rod 12. The baffle 13 abuts against the wooden board 8. The second motor 11 is connected to the control panel 14 for controlling and driving the second motor 11. The threaded rod 12 rotates and performs threaded transmission with the baffle 13 through the drive of the second motor 11, so that the baffle 13 slides on the guide rod, thereby achieving the effect of adjusting the distance between the baffle 13 and the dustproof box 2, thereby achieving the effect of sanding different positions of the wooden board 8 and improving convenience.

[0036] In this method, bearings are fixedly sleeved at both ends of the threaded rod 12. The outer walls of the two bearings are fixedly connected to the fixed plate 10 and the dustproof box 2, respectively, so as to facilitate the rotation of the threaded rod 12. The same guide rod is fixedly connected between the fixed plate 10 and the dustproof box 2. The guide rod is slidably connected to the baffle 13, so as to facilitate the sliding of the baffle 13.

[0037] In this method, through holes are provided on both sides of the dustproof box 2. One end of the wooden board 8 passes through two through holes, and two brush plates 15 are fixedly installed in each of the two through holes. All four brush plates 15 are in contact with the wooden board 8. Two sliding grooves are provided on one side of the dustproof box 2. One end of two of the four transmission rollers 5 slides in the two sliding grooves. Brush plates 26 are fixedly installed in each of the two sliding grooves, and the two brush plates 26 are in contact with the two transmission rollers 5 respectively. Through the dense bristles on the four brush plates 15 and the two brush plates 26, the two through holes and the two sliding grooves on the dustproof box 2 can be sealed, thereby preventing dust leakage and further improving the dustproof effect. At the same time, the four brush plates 15 can also clean the surface of the wooden board 8, preventing dust from adhering to the wooden board 8 and improving product quality.

[0038] Working principle: During use, the control panel 14 controls and drives the first motor 7, the industrial vacuum cleaner 9, the second motor 11, and the two cylinders 3.

[0039] First, one end of the wooden board 8 is passed through the two brush plates 15 in the through hole on one side of the dustproof box 2, so that the wooden board 8 is positioned between the two sanding belts 6. Then, driven by the two cylinders 3 and driven by the two U-shaped plates 4 and the four transmission rollers 5, the two sanding belts 6 are brought into contact with the two sides of the wooden board 8 respectively. Then, driven by the two motors 7, the corresponding transmission rollers 5 are rotated on the two U-shaped plates 4, so that the two sanding belts 6 rotate simultaneously and in opposite directions. In this process, the two sanding belts 6 act on the wooden board 8, thereby achieving the effect of sanding both sides of the wooden board 8 at the same time, improving processing efficiency.

[0040] During the interaction between the two sanding belts 6 and the wooden board 8, the friction between them causes one end of the wooden board 8 to come into contact with the baffle 13. At this time, the baffle 13 can block and limit the wooden board 8.

[0041] Then, the threaded rod 12 is rotated by the drive of the motor 11 and performs threaded transmission with the baffle 13, so that the baffle 13 slides on the guide rod, thereby achieving the effect of adjusting the distance between the baffle 13 and the dust box 2, thereby achieving the effect of sanding different positions of the wooden board 8, and improving convenience.

[0042] At the same time, through the driving of the industrial vacuum cleaner 9 and the cooperation of the suction pipe, the dust in the dust box 2 can be sucked up and collected, further improving the dustproof effect. Meanwhile, the guide plate 18 facilitates the dust to be gathered at the position corresponding to the suction pipe, which makes it easier for the industrial vacuum cleaner 9 to suck up the dust.

[0043] At the same time, the dense bristles on the four brush plates 15 and the two brush plates 16 can seal the two through holes and two sliding grooves on the dustproof box 2, thereby preventing dust leakage and further improving the dustproof effect. In addition, the four brush plates 15 can also clean the surface of the wooden board 8, preventing dust from adhering to the wooden board 8 and improving product quality.

[0044] The technological advancements of this invention compared to existing technologies are as follows: through the cooperation of various components, not only can the sanding of both sides of the wooden board 8 be achieved simultaneously, improving processing efficiency, but the sanding position of the wooden board 8 can also be automatically adjusted, and the dust inside the dustproof box 2 can be automatically sucked up and collected, greatly improving convenience and practicality.
