[0045] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0046] The present invention will be further described below in conjunction with the embodiments.

[0047] Example:

[0048] A fiberboard quality inspection device with an intelligent quality inspection system, such as Figure 1-8 As shown, it includes a feeding conveyor belt 100, which is used to measure the fiberboard and then send it into the quality inspection system. It is worth noting that the staff can perform quality inspection on the board spots or foreign matter on the fiberboard during the sampling process of the fiberboard, and there is no need to perform it again in the quality inspection system. After the fiberboard is sent to the feeding conveyor belt 100, it is only necessary to measure its length, width and thickness, and upload the measured data to the terminal of the intelligent quality inspection system. After the system recognizes and analyzes the data, it adjusts the load of the corresponding loading roller during quality inspection and the positioning of the fiberboard by the subsequent positioning conveyor belt 200 according to the data of the fiberboard;

[0049] Two positioning conveyor belts 200 are respectively arranged at 90 degrees on the left and right sides of the feeding conveyor belt 100, and the intersection of the feeding conveyor belt 100 and the two positioning conveyor belts 200 about the central axis of the three ( Figure 8 The two positioning conveyor belts 200 are respectively used to position the fiberboard and then transfer it to the elastic modulus quality inspection equipment and the static bending strength quality inspection equipment; it is worth noting that the two positioning conveyor belts 200 are centrally symmetrically distributed on both sides of the feeding conveyor belt 100, which facilitates the unified dispatch of the steering mechanism to transfer the fiberboard to the positioning conveyor belts 200 respectively;

[0050] The discharging conveyor belt 300 is arranged opposite to the feeding conveyor belt 100 and its installation height is lower than that of the feeding conveyor belt 100, and is used to feed the fiberboard into the water absorption and expansion quality inspection equipment; it should be noted that the installation height of the discharging conveyor belt 300 is lower than that of the feeding conveyor belt 100 to facilitate the dispatching of the steering mechanism;

[0051] It should be further explained that the technologies for the elastic modulus quality inspection, water absorption expansion quality inspection and static bending strength quality inspection of fiberboard are all mature, and the corresponding equipment are all existing intelligent equipment, which will not be described in detail here. The intelligent quality inspection system in this scheme can adjust the parameters of the above equipment to classify and inspect fiberboards with different values;

[0052] The arc guide rail 400 is formed at the intersection of the extension line of one end of the feed conveyor belt 100 and the positioning conveyor belt 200 ( Figure 8Point A in the figure is the center of the circle), the radius is from the intersection to the guide rail on the far side of the conveyor belt, and the arc length is greater than 85° and less than 90°. It should be noted that the arc of the arc guide rail 400 can not only ensure the effectiveness of the fiberboard transfer, but also avoid collision with the feed conveyor belt 100 and the positioning conveyor belt 200 when switching the working gear, so as to ensure the stability of the device operation; the arc guide rail 400 is divided into ab segment, bc segment and cd segment, the bc segment is perpendicular to the ab segment and the cd segment, and the bc segment is a through hole, one end of the ab segment of the arc guide rail 400 is fixedly connected to a support block 402, and a connecting shaft 403 is connected to a rotating shaft on one side of the support block 402, and the connecting shaft 403 is located at the central axis of the bc segment, and the connecting shaft 403 is connected to the external rotating shaft It is worth noting that the discharging conveyor belt 300 is installed at a lower height than the feeding conveyor belt 100, that is, lower than the height of the arc guide rail 400, so the external rotating driving device connected thereto will not conflict with the position of the discharging conveyor belt 300. The bc segment is perpendicular to the ab segment and the cd segment and the bc segment is a through hole, that is, when the fiberboard is transferred from the feeding conveyor belt 100 to the discharging conveyor belt 300, it passes through the bc segment of the arc guide rail 400, and when the fiberboard is transferred from the feeding conveyor belt 100 to the positioning conveyor belt 200, it only needs to pass through the inner track of the ab segment and the cd segment of the arc guide rail 400. In addition, the external rotating driving device will drive the arc guide rail 400 to move repeatedly within a 180° fan-shaped area, such as Fig. 9 The working gears 1, 2 and 3 in the embodiment can be understood as the cd section of the arc guide rail 400 will not point upwards, and the ab section will not point downwards, so that the arc guide rail 400 will not conflict with the position of the receiving platform 500;

[0053] It also includes a receiving platform 500, which is located between the feeding conveyor belt 100, the discharging conveyor belt 300 and the two positioning conveyor belts 200. The top of the receiving platform 500 is provided with evenly distributed receiving balls 501 for carrying the turning movement of the fiberboard. Specifically, the receiving balls 501 can transport the fiberboard in any direction.

[0054] Furthermore, length measuring components are provided at both the front and rear ends of the feed conveyor 100 bracket, and a supporting gantry 101 is fixedly connected to the middle of the feed conveyor 100 bracket, and a width measuring component and a thickness measuring component are respectively provided on the supporting gantry. Specifically, the length measuring components are divided into two groups and are respectively arranged at the front and rear ends of the feed conveyor 100. The measuring components at the front and rear ends include a hydraulic push rod 111 fixed to the feed conveyor 100 bracket, and the output end of the hydraulic push rod 110 is fixedly connected to a supporting frame 112, and the middle bottom end of the supporting frame 111 of the rear end length measuring component is fixedly connected to an intercepting block 114, and the supporting frame of the front end length measuring component The middle bottom end is fixedly connected with a first electric push rod 112. The length measuring assembly also includes a length contact probe 113, which are respectively arranged at the output end of the first electric push rod 112 and one side of the interception block 114. It is worth noting that the hydraulic push rod 110 is used to control the up and down movement of the support frame 111, so as to intercept the fiberboard through the interception block 114, which is convenient for measuring the fiberboard. The first electric push rod 112 on the rear end length measuring assembly can drive the length contact probe 113 thereon to touch the fiberboard, and the length of the fiberboard is calculated through the contact sensing of the two length contact probes 113 on the fiberboard and the length of the extension of the first electric push rod 112. And send the data to the system terminal; the width measurement components are divided into two groups and are respectively arranged on both sides of the supporting gantry 101. The width measurement components on both sides include a second electric push rod 120 fixedly connected to one end of the supporting gantry 101, and the output ends of the two second electric push rods 120 are fixedly connected to the width contact probe pieces through the connecting plate; it should be noted that after the interception block 114 intercepts the fiberboard, the second electric push rods 120 on both sides extend at the same time, and the extension length is the same, so that the width contact probe piece 121 on the connecting plate can position the fiberboard in the middle while contacting the fiberboard, so that the fiberboard is located in the middle position of the feeding conveyor belt 100, The thickness measuring component detects it and facilitates the subsequent transmission guidance. The width of the fiberboard is calculated and uploaded to the system terminal through the elongation of the two second electric push rods 112; the thickness measuring component includes a pneumatic push rod 130 fixed at the middle position of the supporting gantry 101, and the output end of the pneumatic push rod 130 is fixedly connected to a thickness contact probe piece through a connecting block. It is worth noting that the thickness contact probe piece is not shown. The pneumatic push rod 130 is used to drive the thickness contact probe piece to contact the fiberboard. Compared with hydraulic transmission and electric transmission, it has the characteristics of high speed, which speeds up work efficiency. The thickness of the fiberboard is calculated according to the elongation of the starting push rod and uploaded to the system terminal;

[0055] The entrance end of the positioning conveyor 200 bracket is fixedly connected with a gantry, and the two ends of the gantry are rotatably connected with positioning connecting rods 220 through rotating shafts. The positioning conveyor 200 is processed with a cavity, and the cavity of the positioning conveyor 200 is rotatably connected with uniformly distributed positioning rollers 221. One end of the positioning connecting rod 220 is rotatably connected with a positioning rotating shaft 222. The positioning conveyor 200 bracket is fixedly connected with an electric guide rail 210, and the electric slider of the electric guide rail 210 is fixedly connected with a limited baffle 211. The two positioning rotating shafts 222 It is worth noting that the electric slider of the electric guide rail 210 can move with the limit baffle 211, so as to adjust the position of the positioning shaft 222 in the limit baffle 211, and then change the angle of the two positioning links 220, so that it can finally limit the position of the fiberboard transmitted on the positioning conveyor belt 200, and then complete the positioning of the fiberboard, which is convenient for the subsequent fiberboard to enter the static bending strength quality inspection equipment and the elastic modulus quality inspection equipment, and ensure the stable and effective quality inspection process;

[0056] Fixed brackets 301 are fixedly connected to both sides of the inlet end of the discharging conveyor belt 300 bracket, and a buffer arc plate 302 is fixedly connected between the two fixed brackets 301. It is worth noting that the buffer arc plate 302 can buffer the fiberboard sliding down from top to bottom to prevent it from being bumped and damaged. The conveyor belt is subjected to the immersion test, so there is no need to position the fiberboard;

[0057] Furthermore, the inner sides of the ab and cd sections of the arc guide rail 400 are fixedly connected with a base 411, and a spring 412 is arranged inside the base 411. One end of the spring 412 is fixedly connected with a telescopic seat 413. The telescopic seat 413 is slidably connected to the inner wall of the base 411 on all sides, and the outer end of the telescopic seat 413 is rotatably connected to the guide roller 410 through a bracket. It should be noted that the spring 412 and the telescopic seat 413 enable the guide roller 410 to have a telescopic function, so that in the process of turning the fiberboard, the fiberboard will not be stuck between adjacent guide rollers 410. Specifically, when the fiberboard is pressed against the guide roller 410, the spring 412 inside it is compressed, so that the guide roller 410 has a tendency to extend outward, thereby pushing the fiberboard to move; the inner wall of the bc section of the arc guide rail 400 close to the cd section is rotatably connected to a guide rotating plate 420 through a hinge, and one end of the guide rotating plate 420 The inner wall is rotatably connected to a guide roller 421, and a spare roller 422 is provided on the side of the guide rotating plate 420 close to the CD section. It should be noted that when working gears are one and three, the guide rotating plate 420 is in an open state, and the spare roller 422 thereon is located on the same arc line as the spare roller 422 and the guide roller 410. At this time, the BC section of the arc guide rail 400 is in a closed state, and the fiberboard can turn on the arc guide rail 400 without being stuck by the BC section. When working gear is two, the guide rotating plate 420 is in a closed state, and the BC section of the arc guide rail 400 is in an open state, so that the fiberboard can pass through it; the CD section of the arc guide rail 400 is rotatably connected on both sides with evenly distributed guide shafts 401. It is worth mentioning that the guide shafts 401 provide support for the fiberboard when it moves downward, so as to prevent the fiberboard from tipping over when moving on the arc guide rail 400.

[0058] In this scheme: the staff randomly samples the fiberboards of the same batch, takes out three fiberboards, and puts them into the system in turn, that is, on the feeding conveyor belt 100. When the fiberboard is transmitted to the vicinity of the length measuring component, the length measuring component at the rear end moves downward under the drive of the corresponding hydraulic push rod 110, and makes the interception block 114 intercept the fiberboard, so that the fiberboard stops on the feeding conveyor belt. Then the length measuring component at the front end also moves downward under the drive of its corresponding hydraulic push rod 110, and then the first electric push rod 112 of the front end measuring component extends until it contacts the fiberboard. At this time, the two length contact probes 113 clamp the fiberboard to calculate the length and send the length to the system terminal. Then the first electric push rod 112 on both sides of the supporting gantry 101 is extended. The second electric push rod 120 is extended, so that the width contact probe 121 on it contacts the fiberboard and performs intermediate limit processing on the fiberboard. The fiberboard is located in the middle position of the feeding conveyor 100. The thickness of the fiberboard is calculated by the induction of the two width contact probes 121 and uploaded to the system terminal. At this time, the pneumatic push rod 130 operates, so that the thickness contact probe on its output end touches the fiberboard, thereby calculating the thickness of the fiberboard and uploading it to the system terminal; after the measurement is completed, the hydraulic push rod 110 at the rear end is first started to lift the corresponding support frame 111, and the second electric push rods 120 on both sides are also retracted. At this time, the fiberboard continues to be transmitted, and after the hydraulic push rod 110 at the front end rises upward, the next fiberboard is transmitted to the middle and the above operation is repeated;

[0059] When the first fiberboard passes the measurement, the working gear in the system is one, at this time, the arc guide rail 400 points to the positioning conveyor belt 200 at the elastic modulus quality inspection location, and the guide turn plate 420 of the arc guide rail 400bc section is in an open state, that is, the arc guide rail 400bc section is in a closed state, and the fiberboard first crosses the feed conveyor belt 100, and moves along the track of the arc guide rail 400 under the support of the receiving platform 500. When the fiberboard moves along the arc guide rail 400, it first contacts the guide roller 410 and squeezes the guide roller 410, so that the spring 412 moves with the telescopic seat 413 to the inside of 411. At this time, the spring 412 has a tendency to extend outward, thereby pushing the fiberboard to turn, and the turned fiberboard is on the guide roller 410, the guide roller 421 and the spare Under the guidance of the roller 422, the fiberboard enters the positioning conveyor belt 200. At this time, the system adjusts the position of the electric slider in the electric guide rail 210 on the positioning conveyor belt 200 according to the length and width of the received fiberboard, so that the upper limit baffle 211 of the electric slider moves to the specified position with the positioning shaft 222, causing the positioning link 220 to rotate, thereby making the distance between the tails of the two positioning links 220 equal to the width of the fiberboard. When the fiberboard enters the positioning fiberboard 200, it first contacts the positioning roller 221 in the positioning link 220. Under the guidance of the positioning roller 221, the fiberboard passes through the positioning link 220 at the current angle to realize the function of transmission in the middle position of the positioning conveyor belt 200, so that it is convenient for it to enter the elastic modulus quality inspection equipment for quality inspection. After the quality inspection is completed, the data is uploaded to the system terminal;

[0060] When the second fiberboard passes the measurement, the system controls the external rotary drive device to rotate the arc guide rail 400 90°, and the working gear in the system is changed to two. At this time, the guide turn plate 420 of the bc section of the arc guide rail 400 is in a closed state, and the bc section is in a connected state. The fiberboard enters the bc section of the arc guide rail 400 through the receiving platform 500. At this time, the guide roller on the guide turn plate 420 supports and transmits the fiberboard, so that the fiberboard passes through the bc section of the arc guide rail 400 and moves downward along the cd section of the arc guide rail 400. At this time, the guide shaft 401 supports and transmits the fiberboard. The fiberboard finally crosses the arc guide rail 400 and enters the buffer arc plate 302 on the discharge conveyor belt 300 and then enters the discharge conveyor belt 300, and finally enters the water absorption and expansion quality inspection equipment through the discharge conveyor belt 300. After the quality inspection is completed, the data is uploaded to the system terminal;

[0061] When the third fiberboard passes the measurement, the system controls the external rotary drive device to rotate the arc guide rail 400 again by 90°, and the working gear in the system is changed to three. The guide rotating plate 420 of the arc guide rail 400bc section is in an open state, that is, the arc guide rail 400bc section is in a closed state. The third fiberboard repeats the movement direction of the first fiberboard but with a different direction and finally enters the static bending strength quality inspection equipment. After the quality inspection is completed, the data is uploaded to the system terminal;

[0062] Staff can view the quality inspection data of the batch of fiberboard through the terminal.

[0063] An online quality inspection method for fiberboard quality inspection equipment of an intelligent quality inspection system, such as Fig. 9 , Fig.10 As shown, including:

[0064] S1: A staff member selects three samples from the same batch of fiberboards and puts them on the feeding conveyor belt 100 in sequence;

[0065] S2: The fiberboard is transported on the feed conveyor 100, and the length, thickness and width of the fiberboard are measured, and the measurement data are sent to the system terminal for analysis;

[0066] S3: The fiberboard leaves the feeding conveyor belt 100 and arrives at the receiving platform 500, and is guided by the arc guide rail 400, and is respectively transferred to the positioning conveyor belt 200, the discharging conveyor belt 300, and another positioning conveyor belt 200 at the first, second, and third working gears, and the fiberboard is positioned and transferred on the positioning conveyor belt 200;

[0067] S4: The fiberboard enters the elastic modulus quality inspection device, the water absorption and expansion quality inspection device, and the static bending strength quality inspection device in turn. The system adjusts the load of the loading rollers in the elastic modulus quality inspection device and the static bending strength quality inspection device according to the measurement data, and adjusts the immersion time of the fiberboard in the water absorption and expansion quality inspection device;

[0068] S5: After the quality inspection is completed, each quality inspection data is sent to the terminal.
