[0001] This utility model relates to the field of wood processing technology, and in particular to a wood sanding device. Background Technology

[0002] Wood materials are semi-finished products made from wood. Wood can be processed into products through sanding, cutting, and drilling. Sanding is one of the most common processing methods for wood materials. Nowadays, wood panels need to be sanded during processing. Sanding equipment is used to remove burrs from the surface of the wood panels, making the overall wood panels look smoother and reducing the risk of injury during handling. During the sanding process, workers need to fix the wood panels on the sanding equipment and use the sanding disc to sand one side.

[0003] However, common wood sanding devices are difficult to sand both sides simultaneously, which reduces sanding efficiency. At the same time, it is difficult to adjust the sanding components according to the thickness of the wood, which limits the applicability of the sanding device and reduces its practicality. In view of this, we propose a wood sanding device. Utility Model Content

[0018] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0019] Example

[0020] like Figures 1 to 3 As shown, this utility model proposes a wood sanding device, including a conveying device 1 and a controller 7. A sanding sleeve 2 is fixedly fitted onto the outer surface wall of the conveyor belt of the conveying device 1, facilitating sanding of the bottom surface of the wood board. The controller 7 is fixedly installed on the wall of the conveying device 1 facing forward, and a support cover 3 is fixedly installed on the top wall of the conveying device 1, providing support. The support cover 3 is equipped with a sanding assembly 4 for double-sided sanding of the wood board in conjunction with the sanding sleeve 2. The sanding assembly 4 includes a cylinder 41, an N-shaped frame 42, a sanding roller 43, a guide block 44, and a first small-diameter pulley 45. Two cylinders... 41 is symmetrically installed at two first through holes on the top wall of the support cover 3. The N-shaped frame 42 is set inside the support cover 3. The output ends of the two cylinders 41 pass through the two first through holes respectively and are fixedly connected to the top wall of the N-shaped frame 42, which facilitates the lifting and lowering of the sanding roller 43 set inside the N-shaped frame 42. Due to the lifting and lowering setting of the sanding roller 43, this device can sand wood boards of different thicknesses, improving the practicality of the device. With the sanding roller 43 and the sanding sleeve 2, the purpose of sanding both sides of the wood board at the same time can be achieved. In the automatic conveying state of the conveying device 1, the sanding efficiency of the wood board is improved.

[0021] The two protruding shafts on both sides of the sanding roller 43 are respectively inserted into the second through holes symmetrically opened on the two side walls of the N-shaped frame 42, and the outer ring surface of the protruding shaft is connected to the inner ring surface of the first bearing arranged in the two second through holes. This facilitates the use of the first bearing to assist the sanding roller 43 in rotating on the N-shaped frame 42, without affecting the cylinder 41 in adjusting the height of the sanding roller 43 using the N-shaped frame 42. The third through hole opened on the guide block 44 is provided with a second bearing. The guide block 44 is sleeved on the outer ring surface of the protruding shaft of the sanding roller 43 using the second bearing. A limiting groove is opened on the front wall of the support cover 3. The guide block 44 is set in the limiting groove. The limiting groove guides the N-shaped frame 42 and the sanding roller 43 in the lifting state, which is conducive to the sanding roller 43 maintaining a stable state for height adjustment. The first small diameter pulley 45 is fixedly sleeved on the outer ring surface of the protruding shaft of the sanding roller 43, which facilitates the subsequent rotation of the sanding roller 43.

[0022] Furthermore, a transmission assembly 5 for transmission is installed on the wall facing the front of the conveying device 1 and the grinding assembly 4. The transmission assembly 5 includes a bearing housing 51, a first rotating shaft 52, an auxiliary pulley 53, a belt 54, a second small-diameter pulley 55, and a second rotating shaft 56. The bearing housing 51 is fixedly installed on the wall facing the front of the conveying device 1. The end of the first rotating shaft 52 is connected to the rotating end of the bearing housing 51. The auxiliary pulley 53 is fixedly sleeved on the outer surface wall of the first rotating shaft 52. The bearing housing 51 assists the first rotating shaft 52 in driving the auxiliary pulley 53 to rotate. A third bearing is arranged in the fourth through hole opened on the wall facing the front of the conveying device 1. The end of the second rotating shaft 56 is inserted into the fourth through hole and connected to the drive end of the conveying device 1. With the assistance of the third bearing, the second rotating shaft 56 can drive the second small-diameter pulley 55, which is fixedly sleeved on its outer ring surface, to rotate when the conveying device 1 is started. The transmission is completed by the belt 54 sleeved in the transmission groove of the second small-diameter pulley 55, the first rotating shaft 52 and the first small-diameter pulley 45. Thus, the sanding roller 43 rotates simultaneously with the grinding sleeve 2 under the transmission action. Since the installation of the transmission component 5 and the cooperation of the first small-diameter pulley 45 are in place, there is no need to install a separate drive device for the rotation of the sanding roller 43, thus reducing costs.

[0023] Furthermore, a dust removal assembly 6 is installed on the conveying device 1 to remove dust. The dust removal assembly 6 includes a dust collection hood 61, a suction fan 62, a centralized filter basket 63, and a magnetic plate 64. The dust collection hood 61 is fixedly arranged in an inverted L-shape and is fixedly installed on the conveying device 1. The air inlet end of the dust collection hood 61 is set downwards. The suction fan 62 is fixedly installed at the bottom opening of the vertical structure of the dust collection hood 61, which facilitates the use of the dust collection hood 61 to suck the dust generated during grinding into the dust collection hood 61, thereby achieving dust removal during the grinding process. The purpose is to reduce the workload of subsequent cleaning personnel and reduce dust pollution to the surrounding environment. The magnetic plate 64 is inserted into the side wall opening of the vertical structure of the dust collection hood 61 and is fixedly connected to the outer wall of the centralized filter basket 63 placed inside the dust collection hood 61. The magnetic plate 64 and the dust collection hood 61 are magnetically attracted, which can restrict the position of the centralized filter basket 63. After the dust collection is completed, the magnetic plate 64 can be pulled to move the centralized filter basket 63 out of the dust collection hood 61, so that the staff can clean the impurities in it for subsequent use.

[0024] The above specific embodiments are merely several preferred embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
