Description

Technical Field

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

[0002] During the wood processing, the edges of cut boards often have burrs or unevenness, which require sanding. Traditional sanding equipment relies heavily on manual operation for loading, unloading, and fixing, which is inefficient. Furthermore, the boards are prone to shifting during the sanding process, affecting the sanding quality.

[0003] According to Chinese Patent Publication No. CN223211067U, a rough edge sanding device for wood processing is proposed. The operator can adjust the height of the electric sanding wheel as needed by directly activating the cylinder. The cylinder drives the horizontal plate to slide on the side wall of the long rod through the telescopic rod at the output end, thereby quickly adjusting the height of the electric sanding wheel. When the height is adjusted to the appropriate position, the operator can directly start the motor. The motor drives the reciprocating screw to rotate through the rotating shaft at the output end. When the reciprocating screw rotates, it drives the sleeve block and the electric sanding wheel to move back and forth, thereby achieving better sanding of the board.

[0004] According to the existing technology, in actual use, only the surface of the board can be sanded, but the edges of the board cannot be sanded, and the burrs cannot be completely removed. In addition, according to other existing technologies, in the process of sanding and deburring the edges of the board, after one edge is sanded, the board needs to be removed, the other edge needs to be replaced, and then it needs to be fixed and sanded to remove the burrs. This makes the deburring efficiency of the board low. Therefore, a wood processing edge sanding device is proposed to solve the above problems. Utility Model Content

[0005] (a) Purpose of the utility model To address the technical problems existing in the background art, this utility model proposes a wood processing rough edge sanding device that can automatically position, rotate, and sand boards, and achieve efficient loading and unloading, thereby improving processing efficiency and quality.

[0006] (II) Technical Solution This utility model provides a wood processing edge sanding device, including a base plate, a U-shaped frame on the top of the base plate, a positioning and rotating mechanism inside the U-shaped frame for positioning and rotating the board, a sanding mechanism on the top of the U-shaped frame for sanding the side edges of the board, and a loading and unloading mechanism on the top of the base plate for facilitating loading and unloading of the board.

[0007] The positioning and rotating mechanism includes two displacement blocks located inside a U-shaped frame. A driving assembly is provided on the outer side of the U-shaped frame and is connected to the displacement blocks to drive them to move. A mounting plate is installed on the top of each of the two displacement blocks. A rotating circular plate is provided on one opposite side of each of the two mounting plates.

The output shaft of the servo geared motor is equipped with a rotating shaft extending to the other side of the mounting plate. The rotating shaft is connected to the center of the corresponding rotating circular plate.

[0008] Preferably, the drive assembly includes two first electric push rods mounted on the outside of the U-shaped frame and extending into it. The piston rods of the two first electric push rods are respectively connected to opposite sides of the two displacement blocks. Two first guide rods are mounted on opposite sides of the two displacement blocks. The two first guide rods pass through the U-shaped frame and are slidably connected to it.

[0009] Preferably, the support assembly includes a support ring located on one side of the two mounting plates, four support rods connecting the support ring on the same side to the mounting plate, a fixing ring installed on the opposite side of the two rotating circular plates, and a support groove adapted to the support ring on the inner side of each of the two fixing rings, the support ring being rotatably connected to the corresponding support groove.

[0010] Preferably, the grinding mechanism includes two horizontal plates installed on the left and right side walls of the inner cavity of the U-shaped frame. Each horizontal plate has two sliding rods installed on its top. A lifting plate is slidably connected between the outer sides of the four sliding rods. A second electric push rod extending into the U-shaped frame is installed on its top. The piston rod of the second electric push rod is connected to the top of the lifting plate.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0023] like Figure 1-6 As shown, the present invention proposes a wood processing edge sanding device, including a base plate 1, a U-shaped frame 2 fixedly installed on the top of the base plate 1, a positioning and rotating mechanism 3 provided inside the U-shaped frame 2 for clamping and rotating the board, a sanding mechanism 4 provided on the top of the U-shaped frame 2 for sanding the side edges of the board, and a loading and unloading mechanism 5 provided on the top of the base plate 1 for facilitating automated loading and unloading.

[0024] Example 1, as Figure 2-4 As shown, the positioning and rotating mechanism 3 includes two displacement blocks 31 disposed inside the U-shaped frame 2, and a drive assembly 32 disposed on the outside of the U-shaped frame 2.

[0025] The drive assembly 32 includes two first electric push rods 321 installed on both sides of the U-shaped frame 2 and extending into it. The piston rod of the first electric push rod 321 is connected to the displacement block 31. Two first guide rods 322 are installed on the opposite side of the displacement block 31. The first guide rods 322 pass through the U-shaped frame 2 and are slidably connected to it to ensure that the displacement block 31 moves smoothly. When the first electric push rod 321 is activated, the piston rods of the two first electric push rods 321 will drive the two displacement blocks 31 to move to the opposite side or the opposite side, respectively.

[0026] A mounting plate 33 is fixed to the top of the displacement block 31. A rotating circular plate 34 is provided on the opposite side of the mounting plate 33. A rubber pad 35 is adhered to the opposite side of the rotating circular plate 34 to increase friction and protect the plate.

[0027] A support assembly 36 is provided on the opposite side of the rotating circular plate 34, and the mounting plate 33 is connected to the rotating circular plate 34 through the support assembly 36.

[0028] A servo geared motor 37 is bolted to a mounting plate 33 on one side. The output shaft of the servo geared motor 37 is connected to a rotating shaft 38. The rotating shaft 38 passes through the mounting plate 33 and is fixedly connected to the center of the rotating circular plate 34. When the servo geared motor 37 is started, the output shaft of the servo geared motor 37 will drive the rotating circular plate 34 to rotate.

[0029] The support assembly 36 includes a support ring 361, which is fixedly connected to the mounting plate 33 on the same side by four support rods 362. A fixing ring 363 is fixed on the opposite side of the rotating circular plate 34. A support groove 364 is provided on the inner side of the fixing ring 363. The support ring 361 is embedded in the support groove 364 and can rotate, so that the rotating circular plate 34 can rotate stably under the support of the support assembly 36.

[0030] Specifically, when grinding the board, the board is first lifted by the loading and unloading mechanism 5 and positioned between the two rubber pads 35 on opposite sides. Then, the two first electric push rods 321 are activated simultaneously. Under the action of the support component 36, the two rotating circular plates 34 move to opposite sides. The two rotating circular plates 34 will drive the two rubber pads 35 to move to opposite sides until the opposite sides of the two rubber pads 35 abut against the left and right sides of the board. The board can then be fixed by the two rubber pads 35. Then, the loading and unloading mechanism 5 is reset. The rubber pads 35 increase the friction, which can prevent the board from falling after the loading and unloading mechanism 5 is reset.

[0031] After the board is fixed, the grinding mechanism 4 can grind and deburr the upper edge of the board. After grinding is completed, the grinding mechanism 4 is reset, and then the servo reduction motor 37 is started, so that the rotating circular plate 34 and the rubber pad 35 connected to it rotate. Under the action of the other side support component 36, the rotating circular plate 34 and the rubber pad 35, the board will be rotated. For rectangular boards, after the board rotates 90 degrees, the other edge can be ground by the grinding mechanism 4. For irregularly shaped boards, the angle can be adjusted by rotating the corner of the adjacent side of the board.

[0032] Example 2, as Figure 5 As shown, the grinding mechanism 4 includes a horizontal plate 41, which is fixed to the left and right side walls of the inner cavity of the U-shaped frame 2 by bolts. Two sliding rods 42 are vertically installed on the top of the horizontal plate 41, and lifting plates 43 are slidably connected to the outer sides of the four sliding rods 42.

[0033] A second electric push rod 44 is installed on the top of the U-shaped frame 2. The piston rod of the second electric push rod 44 is connected to the top center of the lifting plate 43. Two second guide rods 45 are installed on the top of the lifting plate 43. The second guide rods 45 pass through the top of the U-shaped frame 2 and are slidably connected thereto to guide the vertical movement of the lifting plate 43.

[0034] A mounting bracket 46 is bolted to the bottom of the lifting plate 43. A belt grinder 47 is bolted to the bottom of the mounting bracket 46. The belt grinder 47 corresponds to the two rubber pads 35 on opposite sides. The specific structure of the belt grinder 47 is the same as that of the belt sander, including a housing, a DC motor, two rotating rollers, and sandpaper. The housing is installed at the bottom of the mounting bracket 46. The two rotating rollers are rotatably connected inside the housing. The sandpaper is connected to the outside of the two rotating rollers. The DC motor is installed on the outside of the housing and is connected to one of the rotating rollers through a reducer. When the DC motor is started, the two rotating rollers drive the sandpaper to perform grinding through the movement of the sandpaper.

[0035] Specifically, after the board is positioned, the second electric push rod 44 and the belt grinder 47 are started. The second electric push rod 44 will drive the lifting plate 43 to move downward. The lifting plate 43 will drive the mounting frame 46 and the belt grinder 47 to move downward. When the sandpaper of the belt grinder 47 comes into contact with the upper edge of the board, the edge can be sanded to remove burrs.

[0036] Example 3, as Figure 6 As shown, the loading and unloading mechanism 5 includes a fixed plate 51, which is fixed to the left and right side walls of the inner cavity of the U-shaped frame 2 by bolts. A third electric push rod 52 is installed at the bottom of the fixed plate 51, and a cross plate 53 is fixed between the piston rods of the two third electric push rods 52. The cross plate 53 is used to lift the plate for loading and unloading.

[0037] Specifically, before sanding the board, the board is placed directly on top of the cross plate 53, so that the board is placed in the direction of the belt sander 47. Then, the two third electric push rods 52 are activated, which will cause the cross plate 53 to move upward, thereby driving the board upward, and further enabling the board to move more quickly between the two rotating circular plates 34.

[0038] When deburring the board, the two third electric push rods 52 need to be activated in reverse to reset the cross plate 53. After the grinding is completed, the two third electric push rods 52 can also be activated to make the cross plate 53 move upward and contact the bottom of the board. At this time, the positioning of the board can be canceled. Then, the two third electric push rods 52 can be activated in reverse to make the board move downward with the cross plate 53, making it easy to remove the board.

[0039] In embodiment four, a PCL controller is installed on the outside of the U-shaped frame 2. The servo geared motor 37, the two first electric push rods 321, the second electric push rod 44, the belt grinder 47, and the two third electric push rods 52 are all electrically connected to the PCL controller. The PCL controller can control the servo geared motor 37, the two first electric push rods 321, the second electric push rod 44, the belt grinder 47, and the two third electric push rods 52.

[0040] It should be noted that the two first electric push rods 321 and the two third electric push rods 52 all adopt synchronous control technology, which enables the two first electric push rods 321 and the two third electric push rods 52 to move synchronously. The synchronous control technology is existing technology and will not be described in detail in this application document.

[0041] Working principle: In use, this woodworking edge-sanding equipment places the board to be sanded on the cross plate 53 of the loading and unloading mechanism 5. The third electric push rod 52 is activated, causing the cross plate 53 to move upwards, thus moving the board upwards and placing it between the two rotating discs 34 of the positioning and rotating mechanism 3. Then, the first electric push rod 321 is activated, pushing the displacement block 31 towards the center, clamping the board through the rotating discs 34 and rubber pads 35. At this point, the third electric push rod 52 can be activated in reverse, causing the cross plate 53 to reset. Next, the second electric push rod 44 and the belt sander 47 are activated. The second electric push rod 44 drives the lifting plate 43 downwards, which in turn drives the mounting frame 46 and the belt sander 47 downwards. When the sandpaper from the belt sander 47 contacts the upper edge of the board, the edge is sanded. After the burrs are removed on one side, the second electric push rod 44 needs to be activated in reverse to reset the belt grinder 47. Then, the servo reducer motor 37 is activated to rotate the connected rotating disc 34 and rubber pad 35. Under the action of the other side support component 36, rotating disc 34, and rubber pad 35, the plate will rotate. After rotating to a certain angle, the second electric push rod 44 can be activated to make the belt grinder 47 contact the edge of the plate and grind the edge. After grinding, the second electric push rod 44 is activated to retract the belt grinder 47. Then, the third electric push rod 52 is activated to rise and drive the cross plate 53 to lift the plate. Next, the first electric push rod 321 is activated in reverse to release the plate. Finally, the third electric push rod 52 is activated in reverse to make the cross plate 53 move the plate downward for easy material removal.

[0042] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
