Description

Technical Field

[0001] The present invention relates to the technical field of composite insulation board production, and particularly relates to a measuring device for detecting the length of a composite insulation board. Background Art

[0002] The composite insulation board uses additives, cement, sand, and mortar as bonding materials; fiberglass mesh cloth and steel bars as reinforcing materials; wood fibers and fly ash as fillers; and polyethylene foam board as the insulation material. The composite insulation board is produced in a factory through a reasonable material ratio and a scientific production process, and can be used in newly built buildings, connecting buildings, renovation of old buildings, conversion of flat roofs to pitched roofs, villas, factory buildings, and rural buildings.

[0003] In the prior art, during the production process of the composite insulation board, it is often necessary to measure its length. The traditional measurement method generally uses a tape measure for measurement. However, when the length of the composite insulation board is relatively long, due to the limited length of the tape measure, when the measurer conducts the measurement, the measurer needs to measure it in segments, and only by calculating the sum of the data can the overall length of the composite insulation board be known. During this process, since the tape measure needs to be recalibrated at the starting point when measuring in segments, there will be a certain error. Then, when measuring in multiple segments, the measurement error will be gradually accumulated and increased, which will affect the measurement accuracy of the composite insulation board. Summary of the Invention

[0004] Aiming at the deficiencies of the prior art, the present invention provides a measuring device for detecting the length of a composite insulation board to solve the problems raised in the above background art.

[0005] The above technical object of the present invention is achieved through the following technical solutions: A measuring device for detecting the length of a composite insulation board includes a base. A mounting frame is fixedly installed on the top surface of the base. A control box is fixedly installed on one side of the base. A mounting plate is arranged inside the mounting frame. A laser generator is arranged on the bottom surface of the mounting plate. The laser generator is electrically connected to the control box. A laser receiver is arranged on the bottom surface of the mounting plate. The laser receiver is electrically connected to the control box. An air compressor is arranged inside the control box. A lifting assembly is arranged inside the mounting frame and is used to drive the mounting plate to lift for measuring composite insulation boards of different heights. A guiding assembly is arranged inside the base and is used to guide the composite insulation board into the mounting frame for measurement. An adjusting assembly is arranged on the bottom surface of the mounting plate and is used to adjust the use distance between the laser generator and the laser receiver to adapt to laser measurement of composite insulation boards of different lengths. The top surface of the base is provided with a limiting component, which is used to limit and fix the composite heat preservation board after it is guided into the interior of the base.

[0006] By adopting the above technical solution, during use, the staff pushes the composite heat preservation board to the top of the base through the guiding component, and then the staff limits and fixes the composite heat preservation board through the limiting component. After the above steps are completed, the staff uses the lifting component through the control box to lower the height of the installation plate and make it located on the top of the composite heat preservation board. Then the staff uses the adjusting component through the control box to adjust the use distance between the laser generator and the laser receiver, so that the laser generator and the laser receiver are respectively located on one side of the composite heat preservation board. Then the staff starts the laser generator and the laser receiver through the control box. At this time, when the laser generator emits a laser beam, the control box measures the time of it. Then when the laser receiver receives the laser beam, the laser receiver feeds back the signal to the control box to stop the timing. Then the control box measures the time difference Δt of the laser pulse from emission to return after being reflected by the target. Using the speed of light c and the atmospheric refraction coefficient n, the overall length of the composite heat preservation board can be obtained according to the time-of-flight calculation formula, thereby achieving the effect of completing the length measurement of the composite heat preservation board with high precision at one time.

Subsequently, under the connection action of the coupling, the two rotating shafts will rotate simultaneously. At this time, the two rotating shafts will drive the driving gear and the driven gear to rotate. Then, under the meshing transmission of the driven gear, the driving gear and the rack, the two racks will drive the mounting plate to move downward and compress a plurality of return springs. Then, when the first pressure sensor at the bottom of the mounting plate contacts the top of the composite heat-insulating board, the first pressure sensor will feedback an electrical signal to the control box to stop the rotation of the driving shaft of the driving motor, thereby achieving the effect of facilitating the lifting and use of the mounting plate.

Two sliding seats are slidably connected inside the base. One side of the base is fixedly provided with a guiding seat, and one side of the guiding seat is an acute-angled inclined surface.

[0010] By adopting the above technical solution, when the staff measures the composite heat-insulating board, the staff pushes a corner of the composite heat-insulating board to the surface of the sliding seat through the inclined surface of the guiding seat. Then, the bottom of the composite heat-insulating board can be supported by the two sliding seats. Subsequently, the rotation of the plurality of first rollers inside the base can drive the two sliding seats and the composite heat-insulating board on their tops to move, thereby achieving the effect of guiding the composite heat-insulating board to the top of the base and facilitating the subsequent measurement of it.

[0011] Preferably, the adjustment assembly includes: a mounting block fixedly installed on the bottom surface of the mounting plate. Air storage grooves are respectively formed on both sides of the mounting block.

A second pressure sensor is fixedly installed on one side of the mounting plate, and the second pressure sensor is electrically connected to the control box.

[0012] By adopting the above technical solution, while the staff uses the lifting component to adjust the use height of the installation plate, the staff uses the air compressor inside the control box to convey compressed air into the two air storage tanks of the installation block. Then, under the action of air pressure, the two connecting columns will drive the two connecting heads and the two transmission boxes to move away from each other and open. Then, when the installation plate touches the top of the composite heat-insulating board, the staff reversely uses the air compressor inside the control box to extract the air inside the two air storage tanks. Then, under the action of negative-pressure air, the two connecting columns will drive the two transmission boxes to retract.

Then, under the thread transmission action of the adjusting screws and the positioning plates, the plurality of pressing plates will displace and press the composite heat-insulating board so that its side edges are attached to the plurality of first limiting plates. In this way, the composite heat-insulating board can be limited and fixed through the plurality of first limiting plates and the plurality of pressing plates, preventing the displacement of the composite heat-insulating board from affecting the measurement effect during measurement.

A plurality of second rollers 16 are rotatably connected inside the guiding seat 15, a conveyor belt 17 is arranged inside the guiding seat 15, and the inner wall surface of the conveyor belt 17 is movably sleeved with the plurality of second rollers 16, which is convenient for reducing the friction between the composite heat-insulating plate and the guiding seat 15 when the composite heat-insulating plate is guided into the top of the base 1, thereby preventing the composite heat-insulating plate from being damaged when it is guided into the top of the base 1. An adjusting hole 14 is opened on one side of the base 1, positioning columns 13 are fixedly installed on one side of the two sliding seats 12, the positioning columns 13 are slidably connected with the adjusting hole 14, and the positioning columns 13 are installed and fixed on the base 1 through nuts. The staff can limit a single sliding seat 12 through the nuts. Furthermore, when the staff uses the sliding seat 12 to receive the composite heat-insulating plate, one sliding seat 12 can first receive a corner of the composite heat-insulating plate, and then after the sliding seat 12 slides the composite heat-insulating plate to a certain position, the staff can release the limit of the other sliding seat 12 to make it slide, so as to improve the position accuracy of the two sliding seats 12 when guiding and receiving the composite heat-insulating plate.

[0034] Working principle: Please refer to Figure 3 As shown, during use, the staff releases the nut limit of one sliding seat 12 far away from the guiding seat 15. Furthermore, the staff lifts a corner of the composite heat-insulating plate and places it on the surface of the conveyor belt 17. Then the staff can push the composite heat-insulating plate to make a corner of it enter the inside of the sliding seat 12. Then the staff continues to push the composite heat-insulating plate to make the sliding seat 12 drive the composite heat-insulating plate to displace. Then when the other corner of the composite heat-insulating plate enters the inside of the other sliding seat 12, the staff releases the limit of the other sliding seat 12, so as to guide the composite heat-insulating plate to the top of the base 1; Referring to Figure 2As shown, after the above steps are completed, the staff rotates multiple handwheels. At this time, the multiple handwheels will drive multiple adjusting screws 8 to rotate. Then, under the screw drive of the adjusting screws 8 and the positioning plates 5, multiple pressing plates 9 will be displaced, and the composite insulation board will be extruded so that its side fits against multiple first limiting plates 6. In this way, the composite insulation board can be limited and fixed by the multiple first limiting plates 6 and the multiple pressing plates 9; Reference Figure 1 , Figure 4 , Figure 5 and Figure 6 As shown, at this time, the staff starts the driving motor 44 through the control box 3. Then, the rotation of the driving shaft of the driving motor 44 will drive the rotating shaft 18 to rotate. Then, under the connection of the coupling 19, the two rotating shafts 18 will rotate simultaneously. At this time, the two rotating rotating shafts 18 will drive the driving gear 22 and the driven gear 21 to rotate. Then, under the gear meshing drive of the driven gear 21, the driving gear 22 and the rack 23, the two racks 23 will drive the mounting plate 4 to move downward and squeeze multiple reset springs 25. Then, when the first pressure sensor 26 at the bottom of the mounting plate 4 contacts the top of the composite insulation board, the first pressure sensor 26 will feedback an electrical signal to the control box 3 to stop the rotation of the driving shaft of the driving motor 44; Reference Figure 1 , Figure 7 , Figure 8 , Figure 9 and Figure 10 , at this time, the staff uses the air compressor inside the control box 3 to deliver compressed air into the two air storage tanks 30 of the mounting block 27. Then, under the action of air pressure, the two connecting columns 32 will drive the two connecting heads 33 and the two transmission boxes 28 to move away from each other and open. Then, when the mounting plate 4 contacts the top of the composite insulation board, the staff reversely uses the air compressor inside the control box 3 to extract the air inside the two air storage tanks 30. Then, under the action of negative pressure air, the two connecting columns 32 will drive the two transmission boxes 28 to retract. Then, the two transmission boxes 28 can be fixed on both sides of the composite insulation board through the two second limiting plates 38 at the bottom of the two transmission boxes 28. After the above steps are completed, the staff starts two electric motors 48 through the control box 3. Then, the rotation of the driving shafts of the electric motors 48 will drive the lead screws 46 to rotate. Then, under the screw drive of the lead screws 46 and the threaded seats 40, the threaded seats 40 will drive the mounting plate 50 to move. Then, when the inner side surface of the mounting plate 50 contacts the composite insulation board, the second pressure sensor 51 will feedback an electrical signal to the control box 3. At this time, the control box 3 controls to stop the driving of the two electric motors 48. Then, the laser generator 7 and the laser receiver 49 can be started through the control box 3 to measure the length of the composite insulation board, thereby achieving the adjustment of the use distance between the laser generator 7 and the laser receiver 49; ReferenceFigure 10 and Figure 11 , at this time, the staff starts the laser generator 7 and the laser receiver 49 through the control box 3. At this time, when the laser generator 7 emits a laser beam, the control box 3 measures the time thereof. Then, when the laser receiver 49 receives the laser beam, the laser receiver 49 feeds back a signal to the control box 3 to stop the timing. Then, the control box 3 measures the time difference Δt of the laser pulse from emission to return after being reflected by the target, and uses the speed of light c and the atmospheric refraction coefficient n. According to the time-of-flight method calculation formula, the overall length of the composite insulation board can be obtained, thereby achieving the effect of completing the length measurement of the composite insulation board with high precision at one time.
