[0002] Wooden door panels are one of the important base materials for wooden doors. During production, the sides of the wooden door panels need to be sanded. Currently, belt sanders are mainly used to sand the sides of the wooden door panels. However, during belt sanding, wood chips are very easy to get embedded in the gaps between the abrasive grains of the belt, which affects the sanding effect of the belt on the door panel. Existing sanders only rely on dust suction ports to remove dust from the belt, so the cleaning effect of the belt is limited. Therefore, necessary improvements are needed. Utility Model Content

[0048] A vacuum cleaner is mounted on the frame 10 and connected to the vacuuming area 40a via a vacuum pipe 41. The vacuum pipe 41 is fixed to the vacuum hood 40 via a support frame 41a.

[0049] The dust hood 40 is equipped with a cleaning structure for cleaning the sander belt 32.

[0050] In this embodiment, the cleaning structure includes:

[0051] The movable seat 50 is slidably connected to the dust cover 40. A linkage block 51 is integrally formed on the movable seat 50, and the linkage block 51 is slidably connected to the first movable port 401.

[0052] The nylon brush wheel 52 is rotatably mounted on the movable base 50 via the shaft 52a. The movable base 50 is equipped with a nylon brush wheel motor 52b, and the bottom of the movable base 50 is also provided with a longitudinal through opening 50a.

[0053] A reciprocating drive device is mounted on the dust cover 40 and is used to control the reciprocating movement of the movable seat 50. In this embodiment, the reciprocating drive device is located in the transmission area 40c.

[0054] In this embodiment, the reciprocating drive device includes:

[0055] The drive wheel 60 is rotatably mounted on the dust cover 40 via a shaft;

[0056] The drive gear 61 is rotatably mounted on the dust cover 40 via a shaft and is spaced apart from the drive wheel 60;

[0057] The driven rack 62 is slidably mounted on the dust cover 40 and meshes with the drive gear 61; in this embodiment, two support blocks 62a are fixedly connected in the transmission area 40c. The support blocks 62a have support openings for the driven rack 62 to slide. The two ends of the driven rack 62 pass through the support openings and are slidably connected to the support blocks 62a.

[0058] The second motor 63 is used to control the rotation of the drive wheel 60;

[0059] The driven rack 62 is connected to the movable seat 50 through the linkage block 51, and an integrally formed drive rod 61a is provided on the drive gear 61. The drive rod 61a has a groove 61b extending along the drive rod 61a, and an eccentric block 600 is eccentrically provided on the drive wheel 60. The eccentric block 600 is inserted into the groove 61b and cooperates with the drive rod 61a.

[0060] In this embodiment, the vacuum cleaner includes:

[0061] The chassis 70 has an internal cavity and an exhaust vent 71;

[0062] Fan 72 is installed at exhaust outlet 71. In this embodiment, the fan is a centrifugal fan.

[0063] The dust collector bag 73 is located in the inner cavity, and the inner cavity is divided into an exhaust chamber 70a and a dust collection chamber 70b.

[0064] The chassis 70 is connected to the dust collection area via a dust collection pipe 41.

[0065] In this embodiment, there are two vacuum cleaners. One vacuum cleaner vacuums the vacuuming area through the suction pipe 41, and the other vacuum cleaner vacuums the cleaning area 40b through the suction pipe 41. The vacuum cover of this embodiment is provided with a plurality of air inlets 80, which are connected to the cleaning area 40b. When the vacuum cleaner fan is started, the air enters the cleaning area through the second movable port or the air inlets and enters the dust collection chamber 70b through the suction pipe.

[0066] In this embodiment, the dust collector bag is installed in the inner cavity via the mounting plate 73a. After the airflow and wood chips enter the dust collection chamber, the wood chips are filtered by the dust collector bag and left in the dust collection chamber, while the airflow passes through the dust collector bag and is discharged by the fan.

[0067] In this embodiment: a door 75 is provided on one side of the chassis 70 by means of bolts, and the dust collection chamber 70b can be cleaned by opening the door.

[0068] In this embodiment, a pressure roller 81 is rotatably connected to the dust collection hood. The pressure roller 81 is located above the conveying roller 20. When the door panel enters the dust collection hood, the pressure roller and the conveying roller 20 cooperate to move the door panel up and down or left and right. At this time, the door panel can only be controlled to move forward by the conveying roller.

[0069] refer to Figures 1-8 The principle of this embodiment is:

[0070] During sanding, the door panel is placed on the conveyor roller and pushed until it moves onto the conveyor roller controlled by the sprocket motor. The conveyor roller then transports the door panel into the dust collection hood. As the door panel moves and passes through the dust collection hood, the sanding belt sands the sides of the door panel. During sanding, two vacuum cleaners in this embodiment start and suck the wood chips generated during sanding into the dust collection chamber through the suction pipe. The nylon brush wheel in the cleaning area in this embodiment can be rotated by a motor. As the nylon brush wheel rotates, it cleans the sanding belt (the rotation direction of the nylon brush wheel is...). (The sanding belt runs in the opposite direction). In addition, this embodiment also includes a reciprocating drive device. When the second motor controls the drive wheel to rotate, the eccentric block controls the drive gear to rotate clockwise or counterclockwise, thereby causing the driven rack to reciprocate and driving the moving seat to reciprocate, thus controlling the nylon brush wheel to reciprocate. The reciprocating nylon brush wheel can prevent impurities from accumulating between the nylon brush wheel and the sanding belt. In other words, the moving nylon brush wheel can facilitate the discharge of impurities, and the discharged impurities are also sucked into the dust collection chamber by the suction pipe.

[0071] Example 2 differs from Example 1 in that:

[0072] refer to Figure 9 This embodiment has two nylon brush wheels 52, spaced apart, and also includes a drive device for driving the nylon brush wheels 52 to rotate, wherein the drive device includes:

[0073] Two pulleys 91 are rotatably connected to the movable seat 60 and are spaced apart;

[0074] The drive belt 92 is connected between the pulleys 91.

[0075] The first motor 93 is used to control the rotation of any pulley 91;

[0076] Each nylon brush wheel 52 corresponds to each pulley 91 and is connected to the pulley 91 via a drive shaft.

[0077] In this embodiment, a first mounting area 94 and a second mounting area 95 are provided on the movable base. The nylon brush wheel 52 is located in the second mounting area, and the drive device is located in the first mounting area. The second mounting area 95 corresponds to the sanding belt.

[0078] refer to Figure 9 In this embodiment, two nylon brush wheels can be set, and the two nylon brush wheels are controlled by a belt pulley drive device. Compared with embodiment 1, this embodiment improves the cleaning effect on the sanding belt by increasing the number of nylon brush wheels.

[0079] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
