Description

Technical Field

[0001] The invention relates to the field of prefabricated plate processing, in particular to a surface treatment device for a prefabricated plate. Background Art

[0002] Precast panels are floor panels used in early 20th century buildings, that is, modules or panels used in engineering projects. They are called precast panels because they are precast concrete parts produced and processed in precast yards and directly transported to construction sites for installation. During the processing of precast panels, the surfaces of the precast panels need to be polished according to different needs. Existing precast panel polishing devices usually use a polishing motor to drive the polishing roller to rotate. When the precast panel passes through the bottom of the polishing roller, the rotating polishing roller polishes the surface of the precast panel. During the polishing process, the dust suction fan is started, and the dust on the surface of the cement precast panel is sucked into the interior of the dust suction fan through the dust suction hood through the dust suction pipe, thereby avoiding a large amount of dust overflowing and affecting the health of the workers. However, the existing precast panel polishing device needs to use two sets of polishing motors to drive two sets of The grinding roller rotates to grind the front and back sides of the prefabricated board respectively. In order to prevent dust from being generated during grinding, the existing prefabricated board grinding device usually grinds the prefabricated board in a relatively closed grinding box. At the same time, in order to be able to grind prefabricated boards of different thicknesses, the existing prefabricated board grinding device makes a group of grinding motors on the upper surface of the prefabricated board be placed in the grinding box. This causes the dust inside the grinding box to enter the grinding box and block the heat dissipation holes of the grinding motor, resulting in reduced heat dissipation efficiency of the grinding motor, thereby causing overheating problems. Secondly, the dust may adhere to the insulating material of the grinding motor, affecting its insulation performance and increasing the risk of short circuit and leakage. Dust particles may even enter the grinding motor, causing increased wear of the grinding motor components and shortening its service life. For this reason, we propose a surface treatment device for prefabricated boards. Summary of the invention

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] When the present invention is in use, the operation of the industrial vacuum cleaner can not only absorb the dust in the receiving hopper, but also enable the dust hood to generate suction to suck the dust attached to the upper surface of the prefabricated board into the industrial vacuum cleaner. In addition, the air exhausted by the industrial vacuum cleaner can be discharged from the exhaust duct one and the exhaust duct two. Since the aperture of the exhaust duct one gradually decreases from one end close to the air outlet pipe to the other end, the temperature of the air will decrease when the air is discharged from the exhaust duct one, and the gas discharged from the exhaust duct one blows toward the motor one, which can accelerate the air flow around the motor one. At the same time, since the temperature of the gas discharged from the exhaust duct one is relatively low, the heat dissipation of the motor one can be accelerated; since the aperture of the exhaust duct two gradually decreases from one end close to the air outlet pipe to the other end, the temperature of the air will decrease when the air is discharged from the exhaust duct two, and the gas discharged from the exhaust duct two blows toward the motor two, which can accelerate the air flow around the motor two. At the same time, since the temperature of the gas discharged from the exhaust duct two is relatively low, the heat dissipation of the motor two can be accelerated.

[0015] When the present invention is in use, when the surface of the prefabricated board is processed, the position of the grinding roller two can be adjusted upward by the servo oil cylinder one according to whether one side or both sides of the prefabricated board is processed, until the hexagonal rod at the lower end of the rotating part is separated from the hexagonal limiting groove on the inner side of the rotating rod, so that when only one side of the prefabricated board needs to be processed, the motor one will drive the grinding roller one to rotate, and the one side of the prefabricated board will be processed, and the grinding roller two will not be driven to rotate, thereby reducing the driving burden of the motor one. If both sides of the prefabricated board need to be processed, the position of the grinding roller two can be adjusted downward by the servo oil cylinder one, so that the hexagonal rod at the lower end of the rotating part is inserted into the hexagonal limiting groove on the inner side of the rotating rod. At this moment, the motor one can drive the grinding roller one and the grinding roller two to rotate at the same time, thereby processing both sides of the prefabricated board, and the servo oil cylinder one drives the grinding roller two to adapt to prefabricated boards of different thicknesses within a certain range; in addition, the motor one is located outside the grinding cover and will not be affected by the dust in the grinding cover, and the air discharged through the exhaust pipe one can accelerate the heat dissipation of the motor one.

[0016] When the present invention is in use, the servo cylinder three is started to drive the lifting frame two to move, so that the multiple groups of limiting rollers two contact the top of the prefabricated board, which can limit the prefabricated board to prevent the prefabricated board from bouncing up and down during the grinding process. The up and down movement of the lifting frame two will simultaneously drive the dust hood to move up and down, so that the distance between the dust hood and the prefabricated board is always appropriate, ensuring that the dust hood can effectively absorb the dust on the upper surface of the prefabricated board.

[0032] Both ends of the grinding cover 5 are open, and both ends of the grinding cover 5 are installed with dust blocking curtains 24; both ends of the grinding cover 5 are open, so that the prefabricated plate can pass through the grinding cover 5; dust blocking curtains 24 are installed at the open ends of the grinding cover 5 to prevent dust generated by grinding from overflowing in large quantities from the open ends of the grinding cover 5.

[0033] A set of supporting legs 25 are fixedly installed at the four corners of the bottom of the frame 1; the frame 1 is stably supported by the four sets of supporting legs 25.

[0034] A mounting frame 26 is fixedly installed on the top of the polishing cover 5, and a servo cylinder 1 603, a servo cylinder 27 and a servo cylinder 3 28 are fixedly installed on the mounting frame 26.

The top of the lifting frame 2 33 is fixedly connected to two groups of guide rods 2 35, and the guide rods 2 35 are slidably penetrated through the inner side of the grinding cover 5. The lifting frame 2 33 is fixedly connected to the dust cover 36, and the dust cover 36 is connected to one end of the spring tube 37. One end of the dust tube 2 38 penetrates the inner side of the grinding cover 5 and is connected to the other end of the spring tube 37. , one end of the dust suction pipe 38 away from the spring pipe 37 is connected to the dust suction pipe 9; when in use, according to the thickness of the prefabricated board, the servo cylinder 3 28 is started to drive the lifting frame 33 to move, so that the multiple groups of limiting rollers 34 contact the top of the prefabricated board, which can limit the prefabricated board; and the lifting frame 33 moves up and down, which will simultaneously drive the dust hood 36 to move up and down, so that the distance between the dust hood 36 and the prefabricated board is always appropriate; the lifting frame 33 can move up and down stably through the two groups of guide rods 35.

[0037] Working principle of the present invention: when the device is used, the prefabricated board whose surface needs to be processed is placed on the transmission roller 12 at one end of the frame 1 away from the motor 2 17, and then the motor 2 17 is started to drive the multiple groups of transmission rollers 12 to rotate, and then the prefabricated board placed on the top of the transmission roller 12 is driven to move; and during the operation of the device, according to the thickness of the prefabricated board, the servo cylinder 2 27 is started to drive the lifting frame 1 30 to move up and down, so that the multiple groups of limiting rollers 1 31 contact the top of the prefabricated board, and the prefabricated board can be limited, and the servo cylinder 3 28 is started to drive the lifting frame 2 33 to move, so that the multiple groups of limiting rollers 2 34 contact the top of the prefabricated board, and the prefabricated board can be limited to avoid the prefabricated board from jumping up and down during the grinding process, and the lifting frame 2 33 moves up and down, which simultaneously drives the dust hood 36 to move up and down, so that the distance between the dust hood 36 and the prefabricated board is always appropriate;

[0038] In the process of processing the surface of the prefabricated board, the servo cylinder 1 603 is started to drive the grinding frame 602 to move up and down. The up and down movement of the grinding frame 602 will drive the grinding roller 2 601 to move up and down to a suitable position until the grinding roller 2 601 contacts the upper surface of the prefabricated board. In the process of the up and down movement of the grinding frame 602, the L-shaped plate 604 will be driven to move up and down. The up and down movement of the L-shaped plate 604 will drive the hexagonal rod at the lower end of the rotating member 608 to slide up and down along the hexagonal limiting groove on the inner side of the rotating rod 611; it should be noted that the top end of the grinding roller 2 is flush with the top end of the transmission roller 12, so that when the prefabricated board moves on the transmission roller 12, the grinding roller 2 can grind the lower surface of the prefabricated board; when the formal grinding is processed, the motor 3 is started. The grinding roller 2 is driven to rotate. The rotating grinding roller 2 can grind the lower surface of the precast plate. At the same time, the grinding roller 2 rotates and drives the rotating rod 611 to rotate under the transmission action of the two sets of mutually meshing bevel gears 613. Since the hexagonal rod at the lower end of the rotating member 608 is inserted into the hexagonal limiting groove on the inner side of the rotating rod 611, the rotation of the rotating rod 611 drives the rotating member 608 to rotate. The rotating member 608 rotates and drives the rotating shaft 606 under the transmission action of the two sets of sprockets 609 and the chain 610. The rotating shaft 606 rotates and drives the grinding roller 601 to rotate under the transmission action of the two sets of mutually meshing bevel gears 607. The rotating grinding roller 601 drives the upper surface of the precast plate to grind.

[0039] If only one side of the prefabricated board to be processed needs to be polished, the servo cylinder 1 603 is started to drive the polishing frame 602 to move upward, so that the rotating member 608 moves upward until the hexagonal rod at the lower end of the rotating member 608 is disengaged from the hexagonal limit groove inside the rotating rod 611. At this time, starting the motor 13 will only drive the polishing roller 12 to rotate, and will not drive the polishing roller 2 601 to rotate, thereby reducing the driving burden of the motor 13. When the prefabricated board is placed on the transmission roller 12, the side of the prefabricated board to be processed faces downward to contact the transmission roller 12.

[0040] During the grinding process, most of the dust generated by grinding will fall directly into the receiving hopper 7 through the gap between the transmission rollers 12, and some of the dust will remain on the upper surface of the prefabricated board. The industrial vacuum cleaner 8 is started and the dust in the receiving hopper 7 is absorbed by the industrial vacuum cleaner 8 through the dust suction pipe 1 9. When the industrial vacuum cleaner 8 is in operation and under the action of the dust suction pipe 1 9, the dust suction pipe 2 38 and the spring pipe 37, the dust suction hood 36 will generate suction, and then the dust remaining on the surface of the prefabricated board can also be sucked into the industrial vacuum cleaner 8 through the dust suction hood 36; when the industrial vacuum cleaner 8 is in operation, the exhaust is carried out through the air outlet pipe 10, and then the air exhausted by the industrial vacuum cleaner 8 can be discharged from the exhaust pipe 1 11 and the exhaust pipe 2 18. The aperture gradually decreases from one end close to the air outlet pipe 10 to the other end. When the air is discharged from the exhaust pipe 11, the temperature of the air will decrease, and the gas discharged from the exhaust pipe 11 blows toward the motor 13, which can accelerate the air flow around the motor 3. At the same time, since the temperature of the gas discharged from the exhaust pipe 11 is relatively low, the heat dissipation of the motor 3 can be accelerated. Since the aperture of the exhaust pipe 2 18 gradually decreases from one end close to the air outlet pipe 10 to the other end, when the air is discharged from the exhaust pipe 2 18, the temperature of the air will decrease, and the gas discharged from the exhaust pipe 2 18 will blow toward the motor 2 17, which can accelerate the air flow around the motor 2 17. At the same time, since the temperature of the gas discharged from the exhaust pipe 2 18 is relatively low, the heat dissipation of the motor 2 17 can be accelerated.

[0041] When the precast plate is transported out of the sanding cover 5 after the processing and sanding are completed, the staff can take the precast plate off the transport roller 12 .

[0042] It should be noted that when the device is used, an external suitable power supply is required, and motor 13, motor 2 17, industrial vacuum cleaner 8, servo cylinder 1 603, servo cylinder 2 27 and servo cylinder 3 28 need to be connected to an external suitable controller, and the external power supply is used to provide power for the operation of motor 13, motor 2 17, industrial vacuum cleaner 8, servo cylinder 1 603, servo cylinder 2 27 and servo cylinder 3 28, and the operation of motor 13, motor 2 17, industrial vacuum cleaner 8, servo cylinder 1 603, servo cylinder 2 27 and servo cylinder 3 28 is controlled by the external controller; and motor 2 17 uses a servo motor.
