Description

Technical Field

[0001] This utility model belongs to the field of inorganic fiberboard production technology, specifically relating to an inorganic fiberboard thickness fixing and polishing system. Background Technology

[0002] Inorganic fiberboard is a new type of building material, made from mineral fibers and resin, with a production process similar to traditional wood fiberboard. In the field of wood fiberboard production, existing technologies typically employ a rotating belt sander in a step-by-step process to process the surface quality. However, this technology is directly applied to inorganic fiberboard. Because inorganic fibers are made of glass, their hardness is far greater than wood, leading to extremely rapid belt wear during the thickness setting stage. This results in high belt consumption and costs, and if belt wear is not detected promptly, it can easily damage equipment. Furthermore, the internal structure of inorganic fiberboard differs from that of traditional wood fiberboard, making it difficult to guarantee consistent quality when using traditional sanding methods. Specifically, the traditional method uses belt sanding for the first thickness setting stage, which wears extremely quickly, affecting sanding stability and significantly reducing production efficiency. Moreover, surface defect detection is treated as an independent process, requiring frequent transfer of boards between different equipment or workstations, increasing the floor space required.

[0003] More importantly, defect detection on the board surface mostly relies on offline vision systems or manual visual inspection, which cannot provide real-time feedback to the preceding process. This results in long feedback times for defective products, leading to material waste and increased rework costs. Furthermore, the lack of data linkage between processes, such as the inability to dynamically optimize sanding parameters based on thickness results, further limits the overall level of intelligent manufacturing. Sanding efficiency and this fragmented processing mode have become major bottlenecks in improving the production efficiency and quality consistency of inorganic fiberboard. Utility Model Content

[0004] This invention provides an inorganic fiberboard thickness fixing and polishing system to address the above-mentioned problems.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: An inorganic fiberboard thickness control and polishing system includes a housing. A board inlet is located on the right side wall of the housing, and a board outlet is located on the left side wall. A lifting and conveying device is located inside the housing. Above the lifting and conveying device, from right to left, are a roller device and multiple dust-collecting devices. A sanding device is located between two adjacent dust-collecting devices. A board surface blower is located between one of the dust-collecting devices and the sanding device. A laser thickness gauge is located above each end of the lifting and conveying device. A vision recognition device is located on one side of the laser thickness gauge at the left end. The system also includes a controller wirelessly connected to the lifting and conveying device, the roller device, the board surface blower, the laser thickness gauge, and the vision recognition device.

[0006] Furthermore, the lifting and conveying device includes a conveying platform, one end of which has a rotating shaft passing through the rear side wall of the housing and is rotatably connected to the hydraulic lifting device, and the controller is wirelessly connected to the hydraulic lifting device.

[0007] Furthermore, the roller device includes a passive roller and an active roller. One end of the passive roller passes through the rear side wall of the housing and is rotatably connected to the second hydraulic lifting device. Both ends of the passive roller are provided with fixed blocks. A spring is fixedly installed on the upper surface of the fixed block. The other end of the spring is connected to a slider. A lead screw is provided on the slider. The upper end of the lead screw is fixedly installed on the inner wall of the top of the housing. A limit block is provided at the lower end of the lead screw. The two sliders are fixedly connected by a connecting rod. One of the sliders is connected to a micro motor through a gear. The micro motor drives the lead screw to achieve micro-adjustment of the passive roller. A sliding groove is provided on the rear side wall of the housing. The sliding groove corresponds to the moving track of the micro motor. The active roller is located to the right of the passive roller. The rotating shaft of the active roller passes through the rear side wall of the housing and is connected to the first motor through a coupling. The first motor is fixedly installed on the outer side wall of the housing through a frame. One end of the active roller is rotatably connected to the third hydraulic lifting device. The controller is wirelessly connected to the micro motor, the first motor, the second hydraulic lifting device, and the third hydraulic lifting device.

[0008] Furthermore, the vacuuming device includes a vacuum pipe that passes through the upper side wall of the housing and connects to the external vacuum main pipe. The distance between the nozzle of the vacuum pipe and the conveying platform is set to 50-70cm.

[0009] Furthermore, the sanding device includes two pulleys connected by a sanding belt, and the rotating shaft of one of the pulleys passes through the rear side wall of the housing and is connected to the second motor via a coupling. The controller is wirelessly connected to the second motor.

[0010] Furthermore, the passive roller is configured as a rubber passive roller, and the outer surface of the active roller is provided with silicon carbide abrasive.

[0011] Compared with the prior art, the present invention has the following advantages: This invention replaces the traditional first thickness determination process for wood fiberboard with a high-hardness, high-wear-resistant roller thickness determination. By setting high-hardness silicon carbide abrasive on the surface of the roller, the service life of the roller is greatly increased.

[0012] The new type of wood sanding system incorporates a board surface blowing and compressed air pulse cleaning structure for cleaning the sanding belt. The main reason for this is that traditional wood sanding dust has a low density, and the dust can be easily sucked away by the dust removal system. However, inorganic fiber dust has a high density and the fibers are fine, making it easy for the dust to adhere to the sanding belt and the surface of the board. Therefore, these two structures are added to turbulent the airflow and create conditions for dust removal.

[0013] This invention integrates a roller device, a sanding device, a laser thickness gauge, and a vision recognition device into one unit. First, the laser thickness gauge scans the plate at the inlet and transmits the scanned data to the controller. The controller sets the height of the roller device, and once set, the roller device contacts the plate to determine the thickness. Then, the sanding device sands the plate that has been thicknessed. After sanding, the plate is inspected by the vision recognition device and the laser thickness gauge to determine whether the thickness determination is complete and whether there is any damage. Finally, the plate passes through the plate outlet via a conveyor platform, completing the process. This optimizes the overall intelligent level of the process and improves the yield rate.

[0014] This invention employs intelligent inspection equipment. A laser thickness gauge is installed at the board inlet to detect the thickness of the incoming board. If the thickness exceeds the standard, the laser thickness gauge will automatically alarm. A laser thickness gauge is installed at the board outlet to detect whether the thickness of the finished board is up to standard. At the same time, a vision recognition device is used to detect whether there are defects on the board surface, thus realizing fully automatic inspection of board quality and greatly saving manpower.

A controller is wirelessly connected to the first hydraulic lifting device 402. Above the lifting and conveying device 4, from right to left, are a roller device 5 and multiple dust collection devices 6. Each dust collection device 6 includes a dust collection pipe 601, which passes through the upper side wall of the housing 1 and connects to an external dust collection main pipe. The opening of the dust collection pipe 601 is connected to the conveying platform 4. The distance between 01 is set to 50-70cm. A sanding device 7 is set between two adjacent dust collection devices 6. A board blower 8 is set between one of the dust collection devices 6 and the sanding device 7. A laser thickness gauge 9 is set above both ends of the lifting and conveying device 4. A vision recognition device 10 is set on one side of the laser thickness gauge 9 on the left end. It also includes a controller. The controller is wirelessly connected to the lifting and conveying device 4, the roller device 5, the board blower 8, the laser thickness gauge 9 and the vision recognition device 10. The sanding device 7 includes two pulleys 701. The two pulleys 701 are connected by a sanding belt 702. The rotation shaft of one of the pulleys 701 passes through the rear side wall of the housing 1 and is connected to the second motor 703 through a coupling. The controller is wirelessly connected to the second motor 703.

[0018] like Figure 4As shown, the roller device 5 includes a passive roller 501 and an active roller 502. The passive roller 501 is a rubber passive roller, and the outer surface of the active roller 502 is provided with silicon carbide abrasive. One end of the passive roller 501 passes through the rear side wall of the housing 1 and is rotatably connected to the second hydraulic lifting device 503. Fixed blocks 504 are provided at both ends of the passive roller 501. A spring 505 is fixedly installed on the upper surface of the fixed block 504. The other end of the spring 505 is connected to a slider 506. A lead screw 507 is provided on the slider 506. The upper end of the lead screw 507 is fixedly installed on the inner wall of the top of the housing 1. A limit block 512 is provided at the lower end of the lead screw 507. The two sliders 506 are fixedly connected by a connecting rod 508. The slider 506 is connected to a micro motor 509 via gears. The micro motor 509 drives the lead screw 507 to achieve micro-adjustment of the passive roller 501. The rear side wall of the housing is provided with a sliding groove, which corresponds to the moving track of the micro motor 509. The active roller 502 is located to the right of the passive roller 501. The rotating shaft of the active roller 502 passes through the rear side wall of the housing 1 and is connected to the first motor 510 via a coupling. The first motor 510 is fixedly mounted on the outer side wall of the housing 1 via a frame. One end of the active roller 502 is rotatably connected to the third hydraulic lifting device 511.

[0019] Workflow: First, the inorganic fiberboard enters the housing 1 through the board inlet 2 and is placed on the conveying platform 401. The conveying platform 401 then rotates at a constant speed, transporting the inorganic fiberboard to the roller device 5. Before entering the roller device 5, the inorganic fiberboard is measured by a laser thickness gauge 9. After the laser thickness gauge completes its measurement, if the thickness does not meet the requirements, it will sound an alarm; if the thickness meets the requirements, the laser thickness gauge 9 will transmit the thickness signal of the inorganic fiberboard to the controller. The controller analyzes and processes the thickness signal and controls the second hydraulic lifting device 503 and the third hydraulic lifting device 511 to lift to the corresponding height, thereby driving the active roller 502 and the passive roller 501 to move up and down. The controller then sequentially activates one... After confirming their positions, motors 510 and 703, along with the controller, fine-tune the passive roller 501 via micro motor 509 to achieve initial thickness determination of the inorganic fiberboard. Next, the initially thickness-determined inorganic fiberboard enters the dust collection device 6 and sanding device 7. Due to the spaced arrangement of the dust collection device 6 and sanding device 7, the inorganic fiberboard undergoes a cycle of dust collection, sanding, dust collection again, sanding again, and dust collection again, achieving post-processing of the inorganic fiberboard. Simultaneously, a board surface blower 8 cleans impurities from the inorganic fiberboard. Finally, the inorganic fiberboard is inspected for thickness using a laser thickness gauge 9 on the left, and a vision detector 10 checks for defects on the board surface. The board is then conveyed to the board outlet 3 via a conveyor platform 401.
