Description

Technical Field

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

[0002] Wood is processed into planks by external cutting devices. Some planks are made by pressing multiple wood chips together. Planks are the base material for many types of furniture. In order to improve the smoothness of the plank surface and ensure product quality, the surface of the planks needs to be sanded and polished before they leave the factory or before they are further processed (e.g., painted).

[0003] In related technologies, it is generally necessary to use sanding equipment (such as belt sanders) to refine the surface of the wood board. However, this equipment can only sand one side of the wood board during operation. After sanding one side, workers need to flip the wood board over to process the other side. When the wood board is large, multiple workers need to work together. This process not only reduces the processing efficiency of the wood board, but also consumes a lot of manpower. Summary of the Invention

[0028] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0029] The wood sanding apparatus of this application according to the accompanying drawings is described below.

[0030] The wood sanding device provided in this application is mainly used after the wood cutting process to perform fine treatment on the surface of the wood. It can sand both sides and the sides of the wood at the same time, which not only improves the processing efficiency of the wood, but also allows the sanding position of the wood to be changed by the rotation of the sanding mechanism, thereby saving a lot of manpower. In addition, this device is also suitable for sanding square timber of various specifications, and can sand three sides of the square timber at the same time, with high processing efficiency.

[0031] like Figures 1-9 As shown, the wood sanding device of this application embodiment may include: a housing 1 and a sanding mechanism 2.

[0032] The housing 1 is vertically positioned relative to the ground via its legs.

[0033] Understandably, the outriggers can reduce the contact area between the housing 1 and the ground, increase the pressure and force between them, and ensure the stability of the housing 1 during operation.

[0034] The grinding mechanism 2 may include a cylinder 21, two sets of grinding components 22, multiple second grinding parts 23, a drive component 24, and a support component 27.

[0035] One end of the cylinder 21 penetrates the outer wall of the shell 1, and the shell 1 is rotatably connected. The cylinder 21 is used to support the two sets of grinding components 22.

[0036] It should be noted that the cylinder 21 and the shell 1 described in this embodiment are rotatably connected by a first bearing (not shown in the figure).

[0037] The drive assembly 24 is located inside the housing 1 and is connected to the cylinder 21. The drive assembly 24 is used to drive the cylinder 21 and the grinding assembly 22 to rotate.

[0038] Two sets of sanding components 22 are symmetrically fitted on the outside of the cylinder 21. The sanding components 22 are used to sand the top and bottom surfaces of the wooden board simultaneously.

[0039] It should be noted that the minimum distance between the two sets of sanding components 22 described in this embodiment is slightly less than the thickness of the wood board to be sanded, thereby ensuring that the sanding components 22 are in contact with the upper and lower surfaces of the wood board and ensuring the sanding effect.

[0040] The polishing component 22 is arranged in a circular structure.

[0041] Understandably, the sanding component 22 is designed in a circular shape. On the one hand, it can continue the advantages of rotary sanding. On the other hand, it makes it convenient for workers to use the rotation of the sanding component 22 to change the sanding position of the wood board. That is, sanding can be carried out whenever the wood board is moved to any position of the sanding component 22.

[0042] The polishing assembly 22 includes a base 221, a plurality of first polishing elements 222 and a cover 223.

[0043] One cover 223 is connected to the cylinder 21, another cover 223 is movably disposed on the outside of the cylinder 21, the base 221 is rotatably disposed inside the cover 223, and multiple first grinding parts 222 are detachably disposed on the base 221.

[0044] It should be noted that the first grinding element 222 described in this embodiment can be made of one or more of bristles, steel wire, nylon wire or sisal wire. The first grinding element 222 can be mounted on the base 221 using a fastener (e.g., screw). The fastener is easy to disassemble and can be replaced after a period of use.

[0045] Multiple second sanding components 23 are respectively disposed on the outer wall of the cylinder 21 and located between the two sanding components 22. The second sanding components 23 are used to sand the sides of the wooden board.

[0046] It should be noted that the second polishing component 23 described in this embodiment can be made of the same material as the first polishing component 222. The second polishing component 23 and the cylinder 21 can be connected by Velcro (not shown in the figure). The second polishing component 23 and the cylinder 21 can also be connected by the fasteners in the above embodiment.

[0047] A support component 27 is disposed on the housing 1, and the support component 27 is sleeved on the outside of a set of grinding components 22.

[0048] Understandably, the support component 27 can overcome the weight of the wood board itself during the sanding process, so as to ensure that the two sanding components 22 exert equal forces on the wood board.

[0049] It should be noted that the housing 1 described in this embodiment is also equipped with a controller (not shown in the figure). The sanding mechanism 2 is connected to the controller. The controller may include a control panel, and the control panel is equipped with a display screen and function buttons, so that relevant personnel can conveniently view the data of the wood sanding device during operation (e.g., the running direction of the sanding mechanism 2, the rotation speed of the sanding component 22, etc.) through the display screen, and conveniently adjust and modify the data by inputting the buttons.

[0050] Specifically, this device is placed in the wood panel production workshop and used to sand and polish the wood panels. First, the worker places the wood panel to be sanded between two sets of sanding components 22. The support component 27 provides auxiliary support for the wood panel, so that the force between the two sets of sanding components 22 and the wood panel is equal during the sanding process, thereby ensuring the uniformity of sanding on the top and bottom surfaces of the wood panel.

[0051] As a possible solution, to save effort, workers can place the planks on an external moving trolley and use the trolley to move the planks to a predetermined position.

[0052] When the device is started, the drive component 24 drives the cylinder 21 to rotate, and the cylinder 21 drives the polishing component 22 to rotate at a constant speed (clockwise). The first polishing part 222 contacts the surface of the wooden board, and then polishes the upper and lower surfaces of the wooden board.

[0053] The first side of the wooden board abuts against the second polishing part 23. The cylinder 21 drives the second polishing part 23 to rotate, thereby polishing the first side of the wooden board. The worker pulls one end of the wooden board and slowly releases the wooden board according to the polishing time, so that the polishing position on the wooden board changes.

[0054] After a portion of the wooden board is sanded, the worker operates an external remote control device (connected to a controller) to cause the drive assembly 24 to slowly rotate the cylinder 21 and the sanding assembly 22 in the opposite direction (counterclockwise). Under the rotation of the sanding assembly 22, the end of the wooden board is transferred to the sanding assembly 22. The worker then applies force to the wooden board, and the end of the wooden board follows the rotation of the sanding assembly 22, causing the remaining unsanded part of the wooden board to be transferred to the other side of the sanding assembly 22. The drive assembly 24 then drives the cylinder 21 and the sanding assembly 22 to accelerate and continue rotating.

[0055] At the same time, the second side of the wooden board abuts against the second sanding part 23, thereby sanding the second side of the wooden board. The worker pulls one end of the wooden board and slowly releases the wooden board according to the sanding time, so that the sanding position on the wooden board changes, thereby realizing the sanding of both sides and the side of the wooden board. The worker can change the sanding position of the wooden board by rotating the sanding mechanism 2, without the need for multiple people to work together, which not only improves the processing efficiency of the wooden board, but also saves a lot of manpower.

[0056] After the sanding is completed, the worker operates the external remote control device again to make the drive component 24 drive the cylinder 21 and the sanding component 22 to rotate (clockwise), thereby sending out the sanded wooden board and completing the unloading.

[0057] It should be noted that the width of the wood board to be sanded in the above embodiment should be smaller than the diameter of the sanding mechanism 2, so that the surface of the wood board can be completely covered when the wood board is processed on one side of the sanding mechanism 2 and then transferred to the other side of the sanding mechanism 2 for sanding.

[0058] In one embodiment of this application, such as Figure 2 and Figure 6 As shown, the polishing mechanism 2 may also include a purification component 26, which may include an impurity collector 261 and a rotating connector 262.

[0059] The outer wall of the cylinder 21 has multiple through slots 260, the impurity collector 261 is set on the inner bottom wall of the shell 1, and the rotating connector 262 is installed between the open end of the cylinder 21 and the impurity collector 261.

[0060] In one embodiment of this application, such as Figure 2 As shown, a cavity 224 is provided between the base 221 and the cover 223, and a groove 41 is provided on the side of the base 221 near the cavity 224.

[0061] Understandably, groove 41 has a certain collecting function.

[0062] Specifically, during the operation of the sanding component 22, a large number of wood chips are generated in contact with the wooden board. Under the action of the impurity collector 261, a negative pressure zone is formed inside the cylinder 21. External air enters the interior of the cylinder 21 through the cavity 224, groove 41 and through slot 260. This device adopts a relatively closed sanding method to collect the wood chips generated during the sanding process, thereby avoiding environmental pollution in the working area.

[0063] As a possible scenario, in order to ensure the sustainable use of this device, a door can be installed on the impurity collector 261. After the device has been used for a period of time, workers can open the door to remove the wood chips accumulated in the impurity collector 261.

[0064] In one embodiment of this application, such as Figures 2-6 As shown, the grinding mechanism 2 may also include an adjustment component 25, which may include a handwheel 251, a screw 252 and a baffle 253.

[0065] One end of the screw 252 passes through the closed end of the cylinder 21 and is rotatably connected to the cylinder 21. The handwheel 251 is installed at one end of the screw 252. The baffle 253 is set inside the cylinder 21 and is threadedly connected to the screw 252. Multiple support plates 254 are integrally formed on the outer wall of the baffle 253. The multiple support plates 254 pass through the through groove 260 and are connected to another cover 223.

[0066] It should be noted that a pressure sensor (not shown in the figure) may be provided between the first grinding element 222 and the base 221 described in this embodiment, and the pressure sensor is connected to the controller.

[0067] Specifically, during the operation of this device, if the force between the upper grinding component 22 and the wooden board is small, the worker can rotate the handwheel 251. The handwheel 251 drives the screw 252 to rotate. The screw 252 is threadedly connected to the baffle 253, which in turn drives the baffle 253 to move. The baffle 253 drives the base 221 to move, thereby reducing the distance between the two grinding components 22 and increasing the force between the grinding component 22 and the wooden board.

[0068] If the dimensions (thickness) of the wood board changes during the sanding process, workers can adjust it using the methods described above.

[0069] Understandably, the baffle 253 can also seal the upper part of the cylinder 21, so that when the impurity collector 261 is running, air and wood dust particles can only enter the interior of the cylinder 21 through the multiple through slots 260 below the baffle 253, thereby improving the dust collection effect of the impurity collector 261.

[0070] In one embodiment of this application, such as Figure 1 and Figure 9 As shown, the support assembly 27 may include multiple bases 271, multiple hydraulic drive devices 272, a ring 273, and multiple balls 274.

[0071] Multiple bases 271 are respectively disposed on the inner wall of the housing 1, and multiple hydraulic drive devices 272 are installed on the corresponding bases 271. The telescopic ends of the hydraulic drive devices 272 penetrate the inner top wall of the housing 1. A ring 273 is sleeved on the outside of a cover 223 and is connected to the telescopic ends of the hydraulic drive devices 272. Multiple balls 274 are respectively installed on the ring 273.

[0072] Specifically, before operating the device, the relevant technicians set the pressure threshold of the grinding assembly 22 (e.g., 10 N) via the controller. The technicians then place the wooden board between the two grinding assemblies 22. Under gravity, the force exerted by the wooden board on the bottom grinding assembly 22 exceeds the set pressure threshold. At this point, the first pressure sensor (located on the bottom grinding assembly 22) sends a signal to the controller, which in turn sends an operating signal to the hydraulic drive device 272. The hydraulic drive device 272 pushes the ring 273 and the ball bearing 274 upwards. The ball bearing 274 contacts the wooden board and applies a pushing force, thereby reducing the force between the wooden board and its bottom grinding assembly 22 until the pressure value meets the preset requirements. The pressure threshold can be calibrated according to actual conditions.

[0073] If the second pressure sensor (located on the upper grinding assembly 22) detects that the pressure on the upper grinding assembly 22 is greater than the pressure threshold, the worker can adjust the pressure between the two by adjusting the assembly 25.

[0074] If the second pressure sensor detects that the pressure on the upper sanding component 22 is in line with the preset value, but not the same as the pressure on the bottom sanding component 22, the hydraulic drive device 272 can continue to run and repeat the above steps until the force between the two sanding components 22 and the wooden board is the same, thereby ensuring the sanding effect of the wooden board.

[0075] In one embodiment of this application, such as Figure 1 , Figure 2 and Figure 7 As shown, the drive assembly 24 may include a drive motor 241, a fixed plate 242, a rotating rod 243, a drive wheel 244, and a driven wheel 245.

[0076] The drive motor 241 is mounted on the fixed plate 242. One side of the fixed plate 242 is connected to the impurity collector 261. One end of the rotating rod 243 is connected to the output shaft of the drive motor 241, and the other end of the rotating rod 243 is rotatably connected to the inner top wall of the housing 1. The driving wheel 244 is mounted on the rotating rod 243, and the driven wheel 245 is mounted on the cylinder 21. The driving wheel 244 and the driven wheel 245 are meshed together.

[0077] Specifically, during the operation of the drive assembly 24, the drive motor 241 drives the rotating rod 243 to rotate, the rotating rod 243 drives the drive wheel 244 to rotate, the drive wheel 244 meshes with the driven wheel 245, thereby driving the driven wheel 245 to rotate, and the driven wheel 245 drives the cylinder 21 and the grinding assembly 22 to rotate.

[0078] In one embodiment of this application, such as Figure 1 and Figure 8 As shown, it may also include an auxiliary component 3, which may include two sets of adaptive telescopic rods 31, a horizontal plate 32 and a vertical plate 33.

[0079] Two sets of adaptive telescopic rods 31 are respectively installed on the housing 1, a horizontal plate 32 is installed on the telescopic ends of the two sets of adaptive telescopic rods 31, and a vertical plate 33 is installed on the horizontal plate 32.

[0080] It should be noted that the adaptive telescopic rod 31 described in this embodiment is equipped with a tension spring (not shown in the figure). Under the action of the tension spring, the adaptive telescopic rod 31 always remains in the retracted state.

[0081] Understandably, the horizontal plate 32 can assist in the installation of the vertical plate 33.

[0082] As a possible scenario, to further ensure the stability of the wood board during processing, an adjusting bolt (not shown in the figure) can be installed on the horizontal plate 32. During the sanding process, the wood board abuts against the vertical plate 33, and the adjusting bolt provides support from below the wood board.

[0083] In one embodiment of this application, such as Figure 1 and Figure 8 As shown, it may also include two limiting plates 34 and two positioning knobs 36.

[0084] Two limiting plates 34 abut against the horizontal plate 32 and the vertical plate 33 respectively. A rotating part 35 is integrally formed on the limiting plate 34. Two positioning knobs 36 are respectively set on the corresponding rotating part 35 and connected to the vertical plate 33.

[0085] Specifically, during the clockwise rotation of the sanding component 22, the sanding component 22 applies a tendency to move towards the auxiliary component 3 to the wooden board. The worker only needs to push the wooden board so that one end of the wooden board abuts against the vertical plate 33, which can ensure the stability during the sanding process.

[0086] After one side of the wooden board is sanded, the sanding assembly 22 rotates in the opposite direction. At this time, the sanding assembly 22 applies a force to the wooden board, and the adaptive telescopic rod 31 can also provide a force to the wooden board, reducing the use of manpower. The worker pulls the wooden board, and when the end of the wooden board moves onto the sanding assembly 22, the worker pushes the wooden board in the direction of rotation of the sanding assembly 22, so that the wooden board enters the other side of the sanding assembly 22.

[0087] Understandably, the limiting plate 34 can play a certain limiting role in the horizontal direction of the wooden board to ensure that the wooden board will not fall off the sanding component 22 during the sanding process. If the specifications of the wooden board change, the worker can change the position of the limiting plate 34 on the horizontal plate 32 and the vertical plate 33 by rotating the positioning knob 36.

[0088] In summary, the wood sanding device of this application embodiment, through two sets of symmetrically arranged sanding components, can sand both sides and the sides of the wood. Workers can change the sanding position of the wood by means of the rotation of the sanding mechanism, without the need for multiple people to work together. This not only improves the processing efficiency of wood but also saves a lot of manpower.
