[0008] Preferably, two first electric lifting rods are installed on both side walls of the workbench. The lifting ends of the first electric lifting rods face upward. The two first electric lifting rods on each side of the workbench form a group. The lifting ends of the two first electric lifting rods in each group are both connected to a lifting plate, and one end of the moving rod close to the lifting plate is movably connected to the lifting plate.

[0009] Preferably, moving sliding grooves are formed on the sides of the two lifting plates close to each other.

[0014] Preferably, a rotating motor is embedded at one end of the rotating rod, and the installation end of the rotating motor is connected to the inner wall of the mounting member.

[0015] Compared with the prior art, the beneficial effects of the present invention are: In the present invention, by providing a lifting block and clamping rods, when the cardboard is conveyed to the end for blanking on the conveyor belt and there is a situation where the cardboard is stuck and cannot be blanked normally, the clamping rods move to the position where the cardboard is stuck. The two clamping rods move towards each other and complete the clamping of both sides of the stuck cardboard. Subsequently, the second electric lifting rod drives the lifting block to rise. Combining with the movement of the clamping rods on the workbench, the auxiliary blanking of the stuck cardboard can be completed. When the cardboard is conveyed to the clamping rod, if it is detected that the cardboard is not placed properly on the conveyor belt, at this time, the clamping rod is driven to expand and contract by the electric telescopic rod, so that the two clamping rods complete the clamping of the edge of the cardboard. Subsequently, by driving the lifting block to rotate through the second rotating motor, the cardboard on the conveyor belt can be straightened, which is convenient for the subsequent measurement of the cardboard and other functional operations of the device; When the device detects the surface flatness of the cardboard, by clamping the cardboard with the clamping plate, the placement stability of the cardboard during the flatness detection of the cardboard can be increased, thereby ensuring the accuracy of the flatness detection result of the cardboard; When the clamping rod abuts against the side of the cardboard, the electric telescopic rod extends with a preset force, so that the clamping rod can squeeze the side of the cardboard. During the squeezing process, the change of the cardboard is photographed by the camera. Through this operation method, the anti-extrusion ability of the cardboard edge can be detected; When detecting the anti-extrusion ability of the cardboard edge, at this time, the rotating roller can be controlled to abut against the surface of the cardboard. Through the continuous pressing of the cardboard by the clamping rod, when the surface of the cardboard deforms, the pressure value detected by the pressure sensor will change. Through this operation method, it can be detected how much extrusion force the cardboard edge can withstand before deforming.

[0016] In the present invention, by providing a movable plate and a sliding block, when detecting the surface flatness of the cardboard, the rotating roller abuts against the surface of the cardboard, and the sliding block slides into the sliding groove, so that the spring telescopic rod squeezes the pressure sensor. The pressure sensor transmits the measured pressure value to the background control system. The rotating roller rolls on the surface of the cardboard. During the rolling process of the rotating roller, the pressure sensor transmits the measured pressure value to the background control system. The background control system compares the change of the pressure value during the rolling process of the rotating roller with the change of the standard pressure value. If the change of the pressure value exceeds the change of the standard pressure value, it means that the surface of the cardboard is uneven.

[0017] In the present invention, by providing a rotating rod, when the cardboard is conveyed on the conveyor belt and moves to the position below the moving rod, the fan in the air groove starts, and at this time, the air outlet blows outwards, so that when the cardboard passes through the bottom of the air outlet, the dust on the surface of the cardboard is removed, so that when the cardboard is conveyed to the next process for processing, there will be no large amount of dust attached to the surface, preventing the dust and debris on the surface of the cardboard from affecting the subsequent detection.

[0023] As a technical optimization solution of the present invention, a second rotating motor 30 is embeddedly installed at the bottom of the lifting block 6. The installation end of the second rotating motor 30 faces downward, and the installation end of the second rotating motor 30 is connected to the lifting end of the second electric lifting rod 5. An electric telescopic rod 8 is embeddedly installed on the lifting block 6. The telescopic end of the electric telescopic rod 8 faces the clamping rod 7, and the telescopic end of the electric telescopic rod 8 is connected to the clamping rod 7. By the second rotating motor 30, the lifting block 6 can be driven to rotate, so that the clamping rod 7 can be adjusted in angle according to different usage requirements. The second electric lifting rod 5 can drive the clamping rod 7 to adjust the height, and the electric telescopic rod 8 can drive the clamping rod 7 to adjust the usage position.

[0024] As a technical optimization solution of the present invention, two first electric lifting rods 3 are installed on both side walls of the workbench 1. The lifting ends of the first electric lifting rods 3 face upward. The two first electric lifting rods 3 on each side of the workbench 1 form a group. The lifting ends of the two first electric lifting rods 3 in each group are both connected to a lifting plate 4. One end of the moving rod 11 close to the lifting plate 4 is movably connected to the lifting plate 4. The first electric lifting rod 3 can drive the lifting plate 4 to adjust the usage height position, so as to adjust the usage height position of the moving rod 11. The moving rod 11 can move on the lifting plate 4 according to the usage requirements.

[0025] As a technical optimization solution of the present invention, moving chutes 9 are provided on the sides of the two lifting plates 4 close to each other. A moving electric slider 10 is installed at one end of the moving rod 11 close to the moving chute 9. The moving electric slider 10 is slidably installed inside the moving chute 9. By sliding the moving electric slider 10 in the moving chute 9, the moving rod 11 can move on the lifting plate 4.

[0026] As a technical optimization solution of the present invention, a displacement chute 16 is provided at the bottom of the moving rod 11. A displacement electric slider 17 is slidably installed inside the displacement chute 16. A first rotating motor 24 is embedded at the top of the movable plate 13, and the installation end of the first rotating motor 24 faces upward. The installation end of the first rotating motor 24 is connected to the bottom of the displacement electric slider 17. By the sliding of the displacement electric slider 17 in the displacement chute 16, the movable plate 13 can move on the moving rod 11, and the first rotating motor 24 can drive the movable plate 13 to rotate on the moving rod 11.

[0027] As a technical optimization solution of the present invention, the detection mechanism includes a sliding block 14 and a rotating roller 15. A plurality of sliding grooves 25 are evenly provided at the bottom of the movable plate 13. A pressure sensor 28 is installed at the top end of the inner wall of the sliding groove 25. A sliding block 14 is slidably installed inside the sliding groove 25. A spring telescopic rod 29 is installed at one end of the sliding block 14 close to the pressure sensor 28. One end of the spring telescopic rod 29 close to the pressure sensor 28 abuts against the pressure sensor 28. A rotating roller 15 is rotatably installed at the end of the sliding block 14 away from the pressure sensor 28. The rotating roller 15 abuts against the surface of the cardboard, and the sliding block 14 slides into the sliding groove 25, so that the spring telescopic rod 29 presses the pressure sensor 28. The pressure sensor 28 transmits the measured pressure value to the background control system. Subsequently, by the sliding of the moving electric slider 10 in the moving chute 9, the moving rod 11 moves on the lifting plate 4, so that the rotating roller 15 rolls on the surface of the cardboard. During the rolling of the rotating roller 15, the pressure sensor 28 transmits the measured pressure value to the background control system. The background control system compares the change in the pressure value during the rolling of the rotating roller 15 with the change in the standard pressure value. If the change in the pressure value exceeds the change in the standard pressure value, it indicates that the surface of the cardboard is uneven.

[0028] As a technical optimization solution of the present invention, stable chutes 26 are provided on both inner walls of the sliding groove 25. A stable slider 27 is slidably installed inside the stable chute 26. One side of the stable slider 27 close to the sliding block 14 is connected to the sliding block 14. By the way that the stable slider 27 slides in the stable chute 26, the sliding stability of the sliding block 14 in the sliding groove 25 can be increased.

[0029] As a technical optimization solution of the present invention, the auxiliary mechanism includes a mounting member 18 and a rotating rod 20. A mounting member 18 is installed on one side of the movable plate 13. A rotating rod 20 is rotatably installed inside the mounting member 18. An air groove 31 is formed inside the rotating rod 20. An opening 21 is formed through one side wall of the air groove 31. A plurality of air outlet holes 23 are uniformly formed through the bottom end of the inner wall of the air groove 31. A blower 22 is installed inside the air groove 31. When the blower 22 inside the air groove 31 is started, the air outlet holes 23 blow air outwards at this time. When the cardboard passes through the bottom of the air outlet holes 23, the dust on the surface of the cardboard is removed, so that when the cardboard is transported to the next process for processing, there will be no large amount of dust attached to the surface, preventing the dust and debris on the surface of the cardboard from affecting the subsequent detection.

[0030] As a technical optimization solution of the present invention, a rotary motor 19 is embedded at one end of the rotating rod 20. The mounting end of the rotary motor 19 is connected to the inner wall of the mounting member 18. The rotary motor 19 drives the rotating rod 20 to rotate, so that the air outlet direction of the air outlet holes 23 can be adjusted according to the use requirements.

[0031] When the present invention is in use, the device is used for the production of agricultural product packaging cartons. The electrical equipment used in the device is powered by connecting to an external power supply through wires. The electrical equipment in the device is controlled by presetting a control system. The conveyor belt 2, pressure sensor 28, camera 12 and blower 22 used in the device are all existing mature technologies, so no more elaboration will be made on them here. The air inlet of the blower 22 is connected to the opening 21 through a conduit.

[0032] Before cutting, the cardboard is placed on the conveyor belt 2 manually by workers or by a manipulator. The cardboard is transported to the cutting equipment at the rear end of the device through the conveyor of the conveyor belt 2. The cutting equipment is an existing mature technology, so no more elaboration will be made on it here. When the cardboard is transported to the clamping rod 7 through the conveyor of the conveyor belt 2, it is photographed by the camera 12, and the photographed data is transmitted to the background control system for graphic comparison. If it is detected that the cardboard is not placed properly on the conveyor belt 2, at this time, the electric telescopic rod 8 drives the clamping rod 7 to expand and contract, so that the two clamping rods 7 complete the clamping of the edge of the cardboard. Subsequently, by driving the lifting block 6 to rotate through the second rotating motor 30, the cardboard on the conveyor belt 2 can be straightened, which is convenient for the subsequent measurement and other functional operations of the device on the cardboard.

[0033] When the cardboard is conveyed to the end of the conveyor belt 2 for discharging, if the camera 12 detects that the cardboard is jammed and cannot be discharged normally, at this time, the auxiliary electric slider 34 slides in the auxiliary chute 33, so that the auxiliary slider 35 drives the clamping rod 7 to the position where the cardboard is jammed. Subsequently, the two clamping rods 7 move closer to each other and complete the clamping of both sides of the jammed cardboard. Then, the second electric lifting rod 5 drives the lifting block 6 to rise. Combining with the movement of the clamping rod 7 on the workbench 1, the auxiliary discharging of the jammed cardboard can be completed.

[0034] When the cardboard is conveyed on the conveyor belt 2 and moves to the position below the moving rod 11, at this time, the first electric lifting rod 3 drives the lifting plate 4 to move to the preset height for use. Subsequently, the rotating motor 19 drives the rotating rod 20 to rotate, and the fan 22 inside the air groove 31 starts. At this time, the air outlet 23 blows air outwards, so that when the cardboard passes through the bottom of the air outlet 23, the dust on the surface of the cardboard is removed, so that when the cardboard is conveyed to the next process for processing, there will be no large amount of dust attached to the surface, preventing the dust and debris on the surface of the cardboard from affecting the subsequent detection.

[0035] This device adopts the method of randomly inspecting the cardboard for quality inspection. When detecting the surface flatness of the cardboard, when the cardboard moves below the moving rod 11, the conveyor belt 2 stops conveying. Subsequently, the two clamping rods 7 move closer to each other to complete the clamping and fixing of the cardboard. Then, the lifting plate 4 moves downward until the rotating roller 15 abuts against the surface of the cardboard, and the sliding block 14 slides into the inside of the sliding groove 25, so that the spring telescopic rod 29 presses the pressure sensor 28. The pressure sensor 28 transmits the measured pressure value to the background control system. Subsequently, by sliding the moving electric slider 10 in the moving chute 9, the moving rod 11 moves on the lifting plate 4, so that the rotating roller 15 rolls on the surface of the cardboard. During the rolling process of the rotating roller 15, the pressure sensor 28 transmits the measured pressure value to the background control system. The background control system compares the change in the pressure value during the rolling process of the rotating roller 15 with the change in the standard pressure value. If the change in the pressure value exceeds the change in the standard pressure value, it indicates that the surface of the cardboard is uneven; The first rotating motor 24 drives the movable plate 13 to rotate, so that the length direction of the movable plate 13 is perpendicular to the length direction of the moving rod 11 in the use state. Subsequently, when the rotating roller 15 abuts against the surface of the cardboard, by sliding the displacement electric slider 17 in the displacement chute 16, the rotating roller 15 can slide horizontally on the surface of the cardboard. Subsequently, according to the above detection method, the secondary detection of the surface flatness of the cardboard in different directions can be completed. Combining the above detection steps, the accuracy of the detection result of the surface flatness of the cardboard by the device can be increased.

[0036] When it is necessary to detect the surface anti-extrusion ability of the cardboard, the second electric lifting rod 5 drives the clamping rod 7 to move upward to the preset use height position. At this time, the bottom of the clamping rod 7 is at the use position above the top of the cardboard. Subsequently, the electric telescopic rod 8 drives the clamping rod 7 to move to the preset use position. Then, under a preset force, the second electric lifting rod 5 causes the clamping rod 7 to squeeze the surface of the cardboard downward. Subsequently, the clamping rod 7 makes a reset movement. The camera 12 takes pictures of the squeezed part of the cardboard for detection. Combining the method of the rotating roller 15 rolling on the squeezed part of the cardboard, finally, through the method of graphic comparison and pressure value change comparison in the background control system, the detection of the surface anti-extrusion ability of the cardboard can be completed.

[0037] When the clamping rod 7 abuts against the side of the cardboard, the electric telescopic rod 8 extends with a preset force, so that the clamping rod 7 can squeeze the side of the cardboard. During the squeezing process, the camera 12 takes pictures of the changes of the cardboard. Through this operation method, the detection of the edge anti-extrusion ability of the cardboard can be completed; When detecting the edge anti-extrusion ability of the cardboard, at this time, the rotating roller 15 can be controlled to abut against the surface of the cardboard. Through the continuous pressing of the clamping rod 7 on the cardboard, when the surface of the cardboard deforms, the pressure value detected by the pressure sensor 28 will change. Through this operation method, it can be detected how much extrusion force the cardboard edge can withstand before it deforms.

[0038] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
