Description

Technical Field

[0001] The invention belongs to the technical field of cardboard detection equipment and relates to a cardboard production process detection and control device. Background Art

[0002] In the cardboard production sector, as packaging, logistics, and other industries increasingly demand higher quality, traditional production processes are facing increasingly prominent challenges: limited testing methods, low automation, and lagging quality control. Existing technologies often rely solely on single-dimensional inspections of cardboard thickness or appearance, lacking comprehensive capabilities for assessing printed image water resistance, print quality stability, and physical strength (such as flat crush strength and puncture resistance). Furthermore, test data cannot be fed back to the production line in real time for dynamic adjustments, making it difficult to quickly identify and remove substandard products.

[0003] Therefore, we propose a cardboard production process detection and control equipment that can automatically sample and handle the cardboard during the production process, perform multi-dimensional detection, and provide real-time data control feedback to ensure the stability of product quality. Summary of the Invention

[0006] The working principle of the present invention is as follows: when in use, the device is docked on one side of the cardboard production line, the transport component randomly extracts the cut cardboard and transports it to the power conveyor belt, the cardboard moves backward with the power conveyor belt, the thickness detection component detects the thickness of the cardboard and transmits the detection result to the control unit, then the visual detection unit detects the length, width and appearance of the cardboard and transmits the detection result to the control unit, then the adsorption and grasping component adsorbs the cardboard and moves the cardboard to the detection position of the strength detection component, performs flat compression strength detection or puncture strength detection on the cardboard, and transmits the detection result to the control unit. The control unit then uses the suction and grabbing components to put the waste back into the power conveyor belt, and the waste enters the waste bin along the power conveyor belt. For cardboard that needs to be tested for water resistance and printing quality stability, after thickness testing, the spray coating component sprays water on the printing on the cardboard. After the power conveyor belt stops for a period of time, the cardboard that has been sprayed with water is transferred to the visual inspection unit for visual inspection. The power conveyor belt then moves the cardboard back to the bottom of the spray coating component, and the spray coating component coats the printing before visual inspection, so as to understand the water resistance and printing quality stability of the printing, and then it enters the waste bin directly.

[0007] The frame is door-shaped, and long strip-shaped through holes are opened on both side walls of the frame in the up and down directions.

At this time, the pressure rod squeezes the pressure sensing unit 1, the power transmission belt drives the cardboard to move, and the rotating wheel rotates. If the thickness of the cardboard changes, the rotating wheel and the pressure rod move up and down, and the value of the pressure sensing unit 1 changes.

[0050] The working principle of the present invention is as follows: when in use, the device is docked on one side of the cardboard production line, the electric screw member 10 drives the suction cup 13 to move forward and backward, the electric screw member 2 11 drives the suction cup 13 to move up and down, when the suction cup 13 contacts the cardboard on the production line, under the action of the vacuum pump, the cardboard is adsorbed, and driven by the electric screw member 10 and the electric screw member 2 11, the cardboard is moved to the top of the power transmission belt 2, the suction cup 13 contacts and adsorbs, and the cardboard is placed on the power transmission belt 2, and the cardboard moves backward with the power transmission belt 2, the electric push rod 16 drives the cross-link telescopic frame 15 to extend and retract, and changes the distribution position of the rotating wheel 19, and the pneumatic push rod 14 drives the cross-link telescopic frame 15 to descend until the rotating wheel 19 contacts the cardboard, at which time the pressure Rod 18 squeezes pressure sensing unit 1 21, power transmission belt 2 drives cardboard to move, rotating wheel 19 rotates, if the thickness of cardboard changes, rotating wheel 19 and pressure rod 18 move up and down, the value of pressure sensing unit 1 21 changes, the control unit detects the abnormal value, and can feed back the problem to the cardboard production line, then visual inspection unit 8 detects the length, width and appearance of cardboard, and transmits the inspection result to control unit, then electric screw part 3 25 drives square track 29 to descend, when circular block 38 disengages from a set of guide plates 39 located above, sector gear 36 and rack 37 engage, and drive shaft 27 and square track 29 to rotate 180 degrees, support plate 40 flips downward, at this time sector gear 36 and rack 37 When the cardboard is disengaged, the circular stopper 38 enters between a group of guide plates 39 located below, and the electric screw rod part 3 25 continues to drive the square track 29 to move downward. The motor 35 drives the power wheel 34 to rotate, driving the movable plate 31 and the supporting plate 40 to move above the cardboard. When the suction cup 2 41 contacts the cardboard, it adsorbs the cardboard, resets the adsorption grabbing component, and moves the cardboard to the corresponding strength detection position. When the cardboard is in the flat pressure strength detection position, the pneumatic push rod 3 42 drives the pressure plate 44 to descend, and performs a flat pressure strength test on the cardboard. The pressure sensing unit 2 43 transmits the data to the control unit in real time. When the cardboard is in the puncture strength detection position, the avoidance port on the supporting plate 40 is aligned with the puncture cone 48, and the pneumatic push rod 4 46 drives the puncture cone 48 to descend, and the cardboard is punctured. The pressure sensing unit 3 47 transmits the data to the control unit in real time. After the strength test is completed, the cardboard waste is put back into the power transmission belt 2, and the waste enters the waste box 9 along the power transmission belt 2. For the cardboard that needs to be tested for water resistance and printing quality stability of the printed picture, after the thickness test, the pneumatic push rod 22 drives the mounting plate 23 and the atomizing nozzle 24 to descend, and the water pump pumps water to the atomizing nozzle 24 to spray the cardboard. After the power transmission belt 2 stops for a period of time, the cardboard sprayed with water is transferred to the visual inspection unit 8 for visual inspection. The power transmission belt 2 then moves the cardboard back to the bottom of the spray coating component 5. After the spray coating component 5 coats the printed picture, a visual inspection is performed to understand the water resistance and printing quality stability of the printed picture.Then it directly enters the waste box 9. The four electric universal wheels 49 can drive the frame 1 to move under the control of the control unit.
