Description

Technical Field

[0001] The invention relates to the field of wood board production, specifically to the field of wood board polishing, and particularly to a sanding machine for wood board production and a use method thereof. Background Art

[0002] Sanding is also called polishing, which refers to the use of sandpaper or a polishing machine to polish the wood board smooth to meet the requirements of use. The mechanical equipment with an automatic feeding system that can complete the sanding work is called a sanding machine.

[0003] When the sanding machine is working, it will inevitably produce a large amount of sawdust, dust, etc. These sawdust and dust will not only easily affect the health of the workers in the surrounding environment, but also the sawdust remaining on the grinding medium (such as sandpaper, sanding belt, etc.) will easily have a negative impact on the next sanding. Based on this point, a search was conducted and a Chinese utility model patent was found. Its authorization announcement number is CN214685798U, which discloses a dust suction device for a sanding belt of a wood board sanding machine. By setting a shielding mechanism, dust and debris (equivalent to dust and sawdust) are shielded, and the dust and debris are absorbed and removed by the reciprocating motion of the dust suction pipe. However, when the wood board is sanded, the sanding belt is in close contact with the surface of the wood board. Therefore, among the sawdust remaining on the sanding belt, some will adhere tightly to the surface of the sanding belt. Although the dust and sawdust in the air can be sucked away by the dust suction pipe, it is difficult to suck away the sawdust tightly adhering to the surface of the sanding belt. Therefore, the cleaning effect is poor and needs to be improved.

[0004] In addition, during the production process of wooden boards, there are sometimes high-strength protrusions on the surface of the wooden boards, such as wood tumors. These protrusions can easily hinder the rotation of the sanding belt, and the sanding belt is generally driven by a motor to rotate. Therefore, in this case, it is easy to cause the power transmission parts to idle and be damaged, or directly hinder the rotation of the motor output shaft and cause damage to the motor.

[0005] Based on the above, the present invention proposes a sanding machine for wood board production and a method of using the same. Summary of the invention

[0006] In order to solve the problems mentioned in the above background, the present invention provides a sanding machine for wood board production and a method of using the same.

[0007] In order to achieve the above technical objectives, the technical solution adopted by the present invention is as follows.

[0010] A cleaning component is provided on the rotating bracket, and a driving component is provided on the mounting bracket. When the wooden board is clamped by the entry and exit components, the grinding roller in contact with the wooden board can be driven by the driving component to rotate, thereby achieving grinding of the surface of the wooden board and the position of the grinding roller is named the grinding position. The cleaning component is used to clean the grinding roller except the grinding position.

[0011] As a further improvement and optimization of the present invention, a third motor for driving the rotating shaft to rotate is arranged on the mounting bracket.

[0012] As a further improvement and optimization of the present invention, the cleaning component includes a cleaning tube rotatably arranged on a rotating bracket, the cleaning tube is coaxial with the rotating shaft, a fine notch is provided on the outer circumferential surface of the cleaning tube, a blowing nozzle is provided at the opening of the fine notch, and the airflow output by the blowing nozzle can be blown to the grinding roller except the grinding position;

[0013] The end of the cleaning pipe is connected with an air supply pipeline, and the end of the air supply pipeline is connected with an air compressor.

[0014] As a further improvement and optimization of the present invention, a convex shaft is provided at the end of the cleaning tube, and the convex shaft is connected to the mounting bracket.

[0015] As a further improvement and optimization of the present invention, the driving component includes a driving shaft installed on a mounting bracket, the driving shaft is coaxial with the grinding roller at the grinding position, a driving seat is provided at one end of the driving shaft facing the grinding roller, a magnet one is provided on the end surface of the driving seat facing the grinding roller, a side seat at one end of the grinding roller facing the driving shaft, a magnet two is provided on the side seat facing the end surface of the grinding roller, and the magnetic poles of magnet one and magnet two are opposite.

[0016] As a further improvement and optimization of the present invention, a second motor for driving the drive shaft to rotate is arranged on the mounting bracket.

[0017] As a further improvement and optimization of the present invention, a cover shell covering the sanding component is provided on the mounting bracket, a connector is provided on the outer surface of the cover shell, an end of the connector is connected to an exhaust pipe, and an end of the exhaust pipe is connected to a blower.

[0018] As a further improvement and optimization of the present invention, the in-and-out component includes an in-and-out roller and a first motor installed on a mounting bracket. The first motor is used to drive the in-and-out roller to rotate. The in-and-out roller is parallel to the rotating axis. In-and-out rollers are provided at both ends of the mounting bracket.

[0019] As a further improvement and optimization of the present invention, an input platform is arranged at one end of the mounting bracket located at the bottom, and an output platform is arranged at the other end.

[0020] A method for using a sanding machine for wood board production:

[0021] Step 1: Clamp the wooden board with the in-and-out components and pull the wooden board to move;

[0022] Step 2: while step 1 is occurring, the driving shaft is driven to rotate by the second motor, and based on the magnetic coupling between the first magnet and the second magnet, the grinding roller at the grinding position can be driven to rotate, thereby achieving grinding of the wooden board;

[0023] Step 3: While step 1 is happening, compressed gas enters the cleaning pipe through the air supply pipe and is blown out at high speed through the blowing nozzle to clean the sawdust from the grinding roller except the grinding position;

[0024] Step 4: After the wood board is polished, the in-and-out components clamp the next wood board. At the same time, the rotating bracket rotates so that the polishing roller that has completed the sawdust cleaning is in the polishing position, and then repeat steps 1 to 3 to polish the next wood board.

[0025] Compared with the prior art, the present invention has the following beneficial effects:

[0026] 1. After each board sanding, the sanding roller will be cleaned, so the effect of each board sanding can be improved. On this basis, at least two sanding rollers are provided, one for sanding the board and the other for cleaning the sawdust, which are used alternately. Therefore, the sanding efficiency will not be affected. In addition, the sanding belt or sandpaper used for sanding has a limited service life. The setting of at least two sanding rollers can also extend the cycle of replacing the sanding belt or sandpaper.

[0027] 2. In this scheme, the high-speed airflow blown out by the blowing nozzle drives the grinding roller to rotate at a high speed. On the one hand, the airflow can blow away some wood chips with weak adhesion. On the other hand, the centrifugal force generated by the high-speed rotation of the grinding roller is distributed radially. Therefore, the centrifugal force can directly push the wood chips from the inside to the outside, making it easier to throw the wood chips away. The combination of the two can quickly clean the residual wood chips on the grinding roller, and the cleaning effect is better.

[0028] 3. In this solution, the grinding roller at the grinding position is driven to rotate through the principle of magnetic coupling to achieve the purpose of grinding. The advantage is that it is easy for technical personnel in this field to think of that each grinding roller corresponds to a motor, but in this way, on the one hand, the cost is too high, and the structure and the power supply of the motor are relatively complicated. On the other hand, when cleaning the wood chips on the grinding roller, the rotation of the grinding roller will rotate with the output shaft of the motor. There is damping in the rotation of the motor output shaft. Therefore, part of the energy of the airflow is wasted, and the cleaning effect is relatively poor. On the one hand, there may be high-strength protrusions such as wood tumors on the wooden board, which can easily hinder the rotation of the grinding roller, thereby causing the load on the motor output shaft to increase and be damaged. In contrast, in this solution, on the one hand, the grinding action can be achieved by one motor, which greatly simplifies the structure. On the other hand, the grinding roller is installed on the rotating bracket through a bearing, and part of the energy of the airflow will not be wasted, so the cleaning effect is better. On the one hand, when encountering protrusions such as wood tumors, the rotation of the grinding roller is hindered, but the motor can still drive the drive shaft to rotate normally, so it can protect the motor.

DETAILED DESCRIPTION

[0039] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the specific implementation mode, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0040] In the accompanying drawings of this scheme, a refers to a wooden board.

[0041] Reference Figure 1-Figure 8 A sanding machine for wood board production includes a base 100, two mounting brackets 105 distributed along the vertical direction, and a linear module 101 arranged on the base 100 and used to pull the two mounting brackets 105 to move closer to or away from each other. The linear module 101 can be realized by using existing technology. For example, two electric telescopic rods are used to drive the two mounting brackets 105 to move respectively, or a motor is used to drive a screw rod to rotate. The screw rod is divided into two sections with opposite spiral directions along the axis, and each section is connected to a mounting bracket 105. The mounting bracket 105 is slidably connected to a linear rail vertically arranged on the base 100, so the rotation of the screw rod can drive the two mounting brackets 105 to move closer to or away from each other.

[0042] Each mounting bracket 105 is provided with an entry and exit component 200 and a sanding component 300. The entry and exit components 200 on the two mounting brackets 105 cooperate to pull the wooden board to move and realize the input or output of the wooden board. The sanding components 300 on the two mounting brackets 105 cooperate to realize the sanding of both sides of the wooden board, which has a higher sanding efficiency.

[0043] Inlet and outlet member 200: see Figure 4 and Figure 5 The in-and-out component 200 includes an in-and-out roller 201 and a first motor 202 mounted on the mounting bracket 105 . The first motor 202 is used to drive the in-and-out roller 201 to rotate. The axis of the in-and-out roller 201 is arranged horizontally. The in-and-out rollers 201 are arranged at both ends of the mounting bracket 105 .

[0044] An import stage 203 is provided at one end of the mounting bracket 105 located below, and an export stage 204 is provided at the other end.

[0045] In the two in-and-out components 200, the areas between the in-and-out rollers 201 at the same end of the mounting bracket 105 are respectively named as the input area and the output area. One end of the wooden board is inserted into the input area by a robot arm technology or manually, and then the two mounting brackets 105 are driven to approach each other by the linear module 101, and the wooden board is clamped by the in-and-out rollers 201, and then the in-and-out rollers 201 are driven to rotate by the first motor 202, thereby pulling the wooden board to move. During the movement, the wooden board is polished by the sanding component 300 located between the input area and the output area, and the polished wooden board is gradually inserted into the output area, and the wooden board is gradually inserted into the output area by the output area. The in-and-out roller 201 in the input zone pulls the wood board away. In a preferred embodiment, the thickness of the polished wood board will change. Therefore, a soft layer supported by soft materials such as rubber or silicone needs to be provided on the outer cylindrical surface of the in-and-out roller 201. When the in-and-out roller 201 in the input zone clamps the wood board, the soft layer will undergo elastic deformation. On the one hand, the clamping is more stable. On the other hand, after the polished wood board is inserted into the output zone, it can also be clamped by the in-and-out roller 201 in the output zone. Although the clamping force is slightly smaller, the wood board can still be pulled away. In addition, the input table 203 and the output table 204 are provided to support the wood board.

[0046] Sanding component 300: Reference Figure 5-Figure 8 The sanding component 300 includes a rotating bracket 303 rotatably arranged on the mounting bracket 105, and a rotating shaft formed at the rotating mounting position is parallel to the in-and-out roller 201. The rotating shaft is driven to rotate by a third motor 302 arranged on the mounting bracket 105, thereby rotating with the rotating bracket 303.

[0047] A grinding roller 304 is rotatably arranged on the rotating bracket 303, and the grinding roller 304 is parallel to the rotating axis. A sanding belt or sandpaper is arranged on the outer circumferential surface of the grinding roller 304 for grinding the wooden board. At least two grinding rollers 304 are arranged in an array along the circumferential direction of the rotating axis, and three are shown in the attached figure of this scheme.

[0048] A cleaning component is provided on the rotating bracket 303, and a driving component is provided on the mounting bracket 105. When the wooden board is clamped by the entry and exit member 200, the grinding roller 304 in contact with the wooden board can be driven by the driving component to rotate, thereby achieving grinding treatment on the surface of the wooden board. After completing the grinding of a wooden board, the rotating bracket 303 is driven to rotate by the third motor 302, and the rotation angle is equal to the angle between two adjacent grinding rollers 304. At the same time, the next wooden board is pulled and moved by the entry and exit member 200. The two cooperate, and the next wooden board is grinded by the next grinding roller 304, that is, the outer surface of the grinding roller 304 that grinds the wooden board each time is clean, thereby ensuring the grinding effect of the wooden board. While grinding, the cleaning component is used to clean the grinding roller 304 used for the previous grinding.

[0049] Reference Figure 6 and Figure 8 The cleaning component includes a cleaning tube 305 rotatably arranged on the rotating bracket 303, the cleaning tube 305 is coaxial with the rotating axis, a fine notch is formed on the outer circumferential surface of the cleaning tube 305, a blowing nozzle 3052 is arranged at the orifice of the fine notch, the airflow outputted by the blowing nozzle 3052 can be blown to any one of the grinding rollers 304 except the grinding roller 304 which is performing the grinding action, so that the grinding roller 304 rotates, since the flow rate of the airflow outputted by the blowing nozzle 3052 is relatively fast, and since the grinding roller 304 is rotatably arranged on the rotating bracket 303, for example, in a bearing assembly manner, the grinding roller 304 rotates at a high speed, on the one hand, the airflow can blow away some wood chips with weak adhesion, on the other hand, the centrifugal force generated by the high-speed rotation of the grinding roller 304 is distributed in the radial direction, therefore, the centrifugal force can directly push the wood chips from the inside to the outside, making it easier to throw the wood chips away, the cooperation of the two can quickly clean the residual wood chips on the grinding roller 304, and the cleaning effect is better.

[0050] A convex shaft 3051 is provided at one end of the cleaning tube 305 , and the convex shaft 3051 is connected to the mounting bracket 105 to ensure that the cleaning tube 305 does not move when the rotating bracket 303 rotates.

[0051] The other end of the cleaning tube 305 is connected to the air supply pipe 102 , and the end of the air supply pipe 102 is connected to equipment such as an air compressor. Compressed air is provided to the cleaning tube 305 through the air compressor and other technologies, thereby outputting high-speed airflow through the nozzle 3052 .

[0052] Reference Figure 5-Figure 8 The driving component includes a driving shaft 306 and a second motor 301 installed on the mounting bracket 105. The position of the grinding roller 304 that is grinding the wooden board is named the grinding position. The driving shaft 306 is coaxial with the grinding roller 304 at the grinding position. The second motor 301 is used to drive the driving shaft 306 to rotate.

[0053] A driving seat 3061 is provided at one end of the driving shaft 306 facing the grinding roller 304, a magnet 1 3062 is provided on the end surface of the driving seat 3061 facing the grinding roller 304, a side seat 3041 is provided at one end of the grinding roller 304 facing the driving shaft 306, and a magnet 2 3042 is provided on the end surface of the side seat 3041 facing the grinding roller 304. The magnetic poles of magnet 1 3062 and magnet 2 3042 are opposite, and the magnetic force between the two is a magnetic adsorption force. Therefore, when the second motor 301 drives the driving shaft 306 to rotate, based on the magnetic coupling between magnet 1 3062 and magnet 2 3042, the grinding roller 304 at the grinding position can be driven to rotate to grind the wooden board.

[0054] Preferred embodiment, refer to Figure 1 and Figure 2 A cover shell 103 covering the sanding component 300 is provided on the mounting bracket 105, and the bottom of the cover shell 103 is open to avoid the sanding action. A connector 1031 is provided on the outer surface of the cover shell 103, and the end of the connector 1031 is connected to an exhaust pipe 104, and the end of the exhaust pipe 104 is connected to an air compressor or a vacuum pump, a blower and other equipment. The air in the cover shell 103 is extracted through the exhaust pipe 104, so as to remove the dust and wood chips generated by sanding.

[0055] Working principle of the present invention:

[0056] The wooden board is clamped and pulled to move by the in-and-out member 200;

[0057] At the same time, when the driving shaft 306 is driven to rotate by the second motor 301, based on the magnetic coupling between the first magnet 3062 and the second magnet 3042, the grinding roller 304 at the grinding position can be driven to rotate to grind the wooden board;

[0058] At the same time, compressed gas enters the cleaning tube 305 through the air supply pipe 102 and is blown out at high speed through the blowing nozzle 3052 to the remaining grinding rollers 304 to clean the wood chips;

[0059] After the wood board is polished, the next wood board is inserted into the input area of ​​the in-and-out member 200. At the same time, the third motor 302 drives the rotating bracket 303 to rotate, so that the next polishing roller 304 that has completed the wood chip cleaning is located at the polishing position to polish the next wood board.

[0060] From the above we can know:

[0061] 1. After each board sanding, the sanding roller will be cleaned, so the effect of each board sanding can be improved. On this basis, at least two sanding rollers are provided, one for sanding the board and the other for cleaning the sawdust, which are used alternately. Therefore, the sanding efficiency will not be affected. In addition, the sanding belt or sandpaper used for sanding has a limited service life. The setting of at least two sanding rollers can also extend the cycle of replacing the sanding belt or sandpaper.

[0062] 2. In this scheme, the high-speed airflow blown out by the blowing nozzle drives the grinding roller to rotate at a high speed. On the one hand, the airflow can blow away some wood chips with weak adhesion. On the other hand, the centrifugal force generated by the high-speed rotation of the grinding roller is distributed radially. Therefore, the centrifugal force can directly push the wood chips from the inside to the outside, making it easier to throw the wood chips away. The combination of the two can quickly clean the residual wood chips on the grinding roller, and the cleaning effect is better.

[0063] 3. In this solution, the grinding roller at the grinding position is driven to rotate through the principle of magnetic coupling to achieve the purpose of grinding. The advantage is that it is easy for technical personnel in this field to think of that each grinding roller corresponds to a motor, but in this way, on the one hand, the cost is too high, and the structure and the power supply of the motor are relatively complicated. On the other hand, when cleaning the wood chips on the grinding roller, the rotation of the grinding roller will rotate with the output shaft of the motor. There is damping in the rotation of the motor output shaft. Therefore, part of the energy of the airflow is wasted, and the cleaning effect is relatively poor. On the one hand, there may be high-strength protrusions such as wood tumors on the wooden board, which can easily hinder the rotation of the grinding roller, thereby causing the load on the motor output shaft to increase and be damaged.

On the one hand, when encountering protrusions such as wood tumors, the rotation of the grinding roller is hindered, but the motor can still drive the drive shaft to rotate normally, so it can protect the motor.
