Description

Technical Field

[0001] This utility model relates to the field of sanding machine technology, specifically to an adaptive pressure regulating sanding machine. Background Technology

[0002] During the production and processing of sheet metal, sanding equipment is needed to polish its surface to make it smooth. Traditional sanders usually use a fixed pressure setting to polish the workpiece surface. When dealing with workpieces of different materials, flatness, and hardness, the fixed pressure is difficult to ensure the consistency and high quality of the polishing effect, thus failing to meet production requirements. When sanding sheet metal, sanding equipment generates a large amount of dust and debris. This dust and debris adheres to the surface of the sanding equipment, and with the high-speed rotation of the sanding equipment, it may cause safety hazards such as dust combustion.

[0003] In the prior art, such as the height-adjustable sander described in patent number CN216991294U, a bracket consisting of a mounting plate, legs, side plates, and support plates is provided. The same set of sanding mechanisms is mounted on the two support plates. The bracket includes a sanding cylinder located between the two support plates. A platform is provided below the sanding cylinder, and the platform includes a table surface located between the two side plates. A lifting mechanism is connected to the underside of the table surface. The lifting mechanism consists of a screw shaft, a threaded seat, and a connecting plate. The lower end of the screw shaft is connected to a drive mechanism for rotating the screw shaft. The drive mechanism drives the screw shaft to rotate, causing the screw shaft to move the threaded seat upwards or downwards. This causes the threaded seat to move the connecting plate via a connecting rod, which in turn causes the connecting plate to move upwards or downwards, thereby adjusting the distance between the table surface and the sanding cylinder to meet the processing needs of objects of different thicknesses.

[0004] Although the aforementioned patent can polish objects, it still has some problems. When the sanding cylinder polishes, it generates a lot of dust and debris. This dust and debris adheres to the surface of the polishing equipment and may affect the normal polishing of the sanding cylinder. At the same time, the pressure of the sanding cylinder on the surface of the object cannot be known, which may affect the polishing quality of the object. Therefore, this utility model provides an adaptive pressure adjustment sander. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an adaptive pressure-adjustable sander, which solves the problem that a large amount of dust and debris is generated during sanding with a sanding cylinder. This dust and debris adhering to the surface of the sanding equipment may affect the normal sanding of the sanding cylinder. At the same time, the pressure of the sanding cylinder on the surface of the object cannot be known, which may affect the sanding quality of the object.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: an adaptive pressure regulating sander, including a belt conveyor, a processing chamber fixedly installed above the belt conveyor, a grinding component arranged inside the processing chamber, and cleaning components arranged on both sides of the grinding component;

[0007] The grinding assembly includes a mounting plate, with two sliding rods slidably passing through the top of the mounting plate. A mounting bracket is fixedly installed at the bottom of the two sliding rods. A grinding cylinder is provided on the inner wall of the mounting bracket, and a pressure sensor is fixedly installed at the top of the mounting bracket.

[0008] The cleaning assembly includes two jet pipes, each with a rotating sleeve fixedly installed at both ends of its outer wall. Two of the four rotating sleeves have one end of their outer wall penetrating the outer wall of the processing chamber and are fixedly installed with gears. Each of the two gears has a rack on one side of its outer wall.

[0009] Preferably, a first electric push rod is fixedly installed at the top of the processing chamber. The output end of the first electric push rod is fixedly connected to the mounting plate. Springs are sleeved on the outside of the two slide rods. One end of the two springs is fixedly connected to the mounting plate, and the other end of the two springs is fixedly connected to the mounting frame.

[0010] Preferably, a stop block is fixedly installed at the bottom of the mounting plate, the stop block is fitted with the pressure sensor, the abrasive cylinder is rotatably installed on the inner wall of the mounting frame, and a motor is fixedly installed on the outer wall of the mounting frame. The output end of the motor passes through the outer wall of the mounting frame and is fixedly connected to one end of the outer wall of the abrasive cylinder.

[0011] Preferably, a second electric push rod is fixedly installed on the outer wall of the processing chamber, and a connecting plate is fixedly installed on the output end of the second electric push rod. The connecting plate is fixedly connected to two racks.

[0012] Preferably, an air compressor is fixedly installed at the top of the processing chamber, and a three-way pipe is fixedly installed at the output end of the air compressor. One end of the three-way pipe is connected to the output end of the air compressor, and the other two ends of the three-way pipe are connected to connecting hoses. Both connecting hoses penetrate the top wall of the processing chamber and are fixedly connected to two jet pipes respectively. Each of the two jet pipes has a set of air outlet nozzles on its outer wall.

[0013] Preferably, a dust suction hood is fixedly installed on each of the two opposite side walls of the processing chamber, and the output ends of the two dust suction hoods penetrate through the side walls of the processing chamber. Flexible shielding curtains are fixedly installed on both sides of the outer wall of the processing chamber. A controller is fixedly installed on the outer wall of the processing chamber, and the controller is electrically connected to the pressure sensor, the first electric push rod, and the motor, respectively.

[0014] Beneficial effects

[0015] This invention provides an adaptive pressure-adjustable sander. Compared with the prior art, it has the following advantages:

[0016] (1) During the grinding process of this adaptive pressure regulating sander, some dust and debris may adhere to the surface of the grinding components. In order to prevent these dust and debris from affecting the normal grinding of the grinding cylinder, the air compressor can be turned on. The air compressor generates compressed air, which is delivered to the jet pipe through the three-way pipe and the connecting hose. The air nozzle on the jet pipe sprays out the compressed air to blow away and clean the dust and debris adhering to the surface of the grinding components. At the same time, in order to improve the cleaning effect on the surface of the grinding components, the second electric push rod can be turned on. The second electric push rod drives the two racks to rise and fall through the connecting plate. During the rise and fall of the two racks, the two gears are driven to rotate. When the two gears rotate, they drive the two jet pipes to rotate through the rotating sleeve, so that the jet pipes swing within a certain range, thereby improving the cleaning quality of dust and debris on the surface of the grinding components. At the same time, the high-speed airflow can also cool the surface of the grinding components, reducing the probability of dust combustion and other safety hazards caused by dust and debris accumulating on the surface of the grinding components.

[0017] (2) When the sander needs to use the sanding cylinder to sand the board, the first electric push rod is turned on to drive the sanding cylinder to descend until the sanding cylinder contacts the surface of the board. At this time, the sanding cylinder and the mounting bracket will be subjected to the reaction force of the board, so that the pressure sensor contacts the stop block. The pressure sensor feeds back the pressure signal to the controller to obtain the pressure magnitude of the pressure sensor. If the pressure is too high, the controller controls the first electric push rod to rise a certain distance, thereby reducing the pressure of the sanding cylinder on the board; if the pressure is too low, the controller controls the first electric push rod to continue to push downward to increase the pressure, thereby realizing the adaptive pressure adjustment of the sanding cylinder on the board to adapt to the sanding needs of boards with different materials, flatness and hardness.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] This utility model provides two technical solutions:

[0027] like Figures 1-6 As shown, this utility model provides an adaptive pressure regulating sander, including a belt conveyor 1, a processing chamber 2 fixedly installed above the belt conveyor 1, a grinding component 3 inside the processing chamber 2, and cleaning components 4 on both sides of the grinding component 3. The belt conveyor 1 is the prior art and can drive the board to move.

[0028] The grinding assembly 3 includes a mounting plate 32 with two sliding rods 33. The sliding rods 33 penetrate the mounting plate 32 and are slidably connected to it. The two sliding rods 33 are vertically oriented. A mounting bracket 37 is fixedly mounted at the bottom of each sliding rod 33. A spring 34 is fitted around each sliding rod 33; one end of the spring 34 is fixedly connected to the bottom of the mounting plate 32, and the other end is fixedly connected to the top of the mounting bracket 37. The mounting bracket 37 is U-shaped and contains a grinding cylinder 38. The grinding cylinder 38 is rotatably connected to the inner wall of the mounting bracket 37. A motor 39 is mounted on the outer wall of the mounting bracket 37. The output shaft of the motor 39 penetrates the side wall of the mounting bracket 37 and is fixedly connected to one end of the grinding cylinder 38. The motor 39 can... The grinding cylinder 38 is able to rotate rapidly to polish the surface of the board. A pressure sensor 36 is fixedly installed at the top of the mounting bracket 37, and a stop block 35 is fixedly installed at the bottom of the mounting plate 32. The stop block 35 is fitted to the pressure sensor 36. When the grinding cylinder 38 applies pressure to the board, the grinding cylinder 38 will be subjected to the reaction force caused by the board, which will cause the pressure sensor 36 to rise and be squeezed by the stop block 35, thereby detecting the pressure of the grinding cylinder 38 on the board. The mounting plate 32 is installed on the top of the processing chamber 2 by a first electric push rod 31. The movable end of the first electric push rod 31 is placed inside the processing chamber 2 and fixedly connected to the top of the mounting plate 32. The first electric push rod 31 is existing technology and can drive the mounting plate 32 to move up and down.

[0029] The grinding cylinder 38 is rotatably mounted on the inner wall of the mounting frame 37. The motor 39 is fixedly mounted on the outer wall of the mounting frame 37. The output end of the motor 39 passes through the outer wall of the mounting frame 37 and is fixedly connected to one end of the outer wall of the grinding cylinder 38. The motor 39 can drive the grinding cylinder 38 to rotate quickly, thereby polishing the surface of the board.

[0030] The cleaning component 4 includes two jet pipes 44, which are respectively located on opposite sides of the abrasive cylinder 38. The interior of each jet pipe 44 is hollow, and each of the two jet pipes 44 has a set of air nozzles communicating with the interior on the side closest to each other. Rotating sleeves 45 are fixedly installed on the outer walls of both ends of the jet pipes 44. The rotating sleeve 45 at one end of the jet pipe 44 is rotatably connected to the inner wall of the processing chamber 2, and the rotating sleeve 45 at the other end of the jet pipe 44 passes through the side wall of the processing chamber 2 and can rotate relative to the outer wall of the processing chamber 2. A gear 46 is fixedly installed on the end of the rotating sleeve 45 that passes through the outer wall of the processing chamber 2 and is located outside the processing chamber 2. A second electric push rod 49 is fixedly installed on the side wall of the processing chamber 2 through which the rotating sleeve 45 passes. A connecting plate 48 is fixedly installed on the movable end of the second electric push rod 49. The connecting plate 48 is provided with two racks 47 that mesh with two gears 46 respectively. The second electric push rod 49 is arranged in a vertical direction. The second electric push rod 49 is existing technology. The movement of the movable end of the second electric push rod 49 drives the connecting plate 48 to move, which in turn drives the two racks 47 to rise and fall at the same time. The rise and fall of the two racks 47 drives the two gears 46 to rotate. The rotation of the gears 46 drives the rotating sleeve 45 to rotate, which in turn drives the jet pipe 44 to rotate to achieve multi-angle cleaning.

[0031] An air compressor 41 is fixedly installed at the top of the processing chamber 2. A three-way pipe 42 is fixedly installed at the output end of the air compressor 41. One end of the three-way pipe 42 is connected to the output end of the air compressor 41, and the other two ends of the three-way pipe 42 are connected to connecting hoses 43. Both connecting hoses 43 penetrate the top wall of the processing chamber 2 and are connected to two jet pipes 44 respectively. When the jet pipes 44 rotate within a certain range, the connecting hoses 43 will move accordingly without affecting the normal rotation of the jet pipes 44. The air compressor 41 is existing technology and can compress air and generate a high-speed airflow. The airflow is delivered to the jet pipes 44 through the three-way pipe 42 and the connecting hoses 43, and then the air is sprayed out by the air nozzle, thereby blowing away the dust and debris attached to the surface of the grinding component 3, preventing the accumulation of dust and debris on the surface of the grinding component 3, and reducing the probability of safety hazards such as dust combustion caused by dust and debris accumulation.

[0032] Dust hoods 5 are fixedly installed on the two opposite side walls of the processing chamber 2. The output ends of the two dust hoods 5 penetrate through the side walls of the processing chamber 2 and are used to connect with an external dust collection device. The external dust collection device creates negative pressure in the dust hoods 5, thereby collecting and processing the dust and debris inside the processing chamber 2. A notch is provided at the bottom of the processing chamber 2 corresponding to the position where the board passes, allowing the board to enter and exit the processing chamber 2 normally. A flexible shielding curtain 6 is fixedly installed on the outer wall of the processing chamber 2 at the position corresponding to the notch. The flexible shielding curtain 6 can block the notch and effectively reduce the speed at which dust diffuses from the inside of the processing chamber 2 into the external environment. The flexible shielding curtain 6 will not obstruct the normal conveying of the board. It can swing or deform naturally with the entry and exit of the board, ensuring that the board can pass smoothly through the passage of the processing chamber 2 while blocking dust. A controller 7 is fixedly installed on the outer wall of the processing chamber 2. The controller 7 is electrically connected to the pressure sensor 36, the first electric push rod 31 and the motor 39 respectively. The controller 7 is existing technology and can receive the pressure data transmitted by the pressure sensor 36. It controls the pressure of the abrasive cylinder 38 on the plate by controlling the extension and retraction of the first electric push rod 31. The pressure sensor 36 is existing technology and can be squeezed by the abutment 35 to detect the magnitude of the reaction force on the abrasive cylinder 38 and convert the pressure signal into an electrical signal to feed back to the controller 7.

[0033] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0034] During operation, when the board needs to be sanded, the board is first placed on the surface of the belt conveyor 1. The belt conveyor 1 is then turned on to transport the board. The board then passes through the flexible baffle curtain 6 and enters the processing chamber 2. At this point, the motor 39 is turned on, causing the sanding cylinder 38 to rotate rapidly. The first electric push rod 31 is activated, causing the sanding cylinder 38 to descend until it contacts the surface of the board. At this point, the sanding cylinder 38 and the mounting bracket 37 are subjected to the reaction force of the board, causing the pressure sensor 36 to contact the abutment block 35. The pressure sensor 36 then transmits the pressure signal. The signal is fed back to the controller 7 to determine the pressure received by the pressure sensor 36. If the pressure is too high, the controller 7 controls the first electric push rod 31 to rise a certain distance, thereby reducing the pressure of the sanding cylinder 38 on the board. If the pressure is too low, the controller controls the first electric push rod 31 to continue to push downward, increasing the pressure. This achieves adaptive pressure adjustment of the sanding cylinder 38 on the board to meet the sanding needs of boards with different materials, flatness, and hardness. Then, the output ends of the two dust hoods 5 are connected to the dust collection device, so that the dust hoods 5 generate negative pressure, allowing the dust hoods 5 to suck up... Some dust and debris may adhere to the surface of the grinding component 3 during the grinding process. To prevent this dust and debris from affecting the normal grinding of the grinding cylinder 38, the air compressor 41 can be turned on. The air compressor 41 generates compressed air, which is delivered to the jet pipe 44 through the three-way pipe 42 and the connecting hose 43. The air nozzle on the jet pipe 44 sprays out the compressed air to blow away and clean the dust and debris adhering to the surface of the grinding component 3. At the same time, to improve the cleaning effect on the surface of the grinding component 3, the second electric push rod 49 can be turned on. The second electric push rod 49 drives the two racks 47 to rise and fall through the connecting plate 48. During the rising and falling process, the two racks 47 drive the two gears 46 to rotate. When the two gears 46 rotate, they in turn drive the two air jet pipes 44 to rotate through the rotating sleeve 45, so that the air jet pipes 44 swing within a certain range, thereby improving the cleaning quality of dust and debris on the surface of the grinding component 3. At the same time, the high-speed airflow can also cool the surface of the grinding component 3, reducing the probability of dust combustion and other safety hazards caused by dust and debris accumulating on the surface of the grinding component 3.
