Before placement, the negative pressure pipe is connected to the negative pressure equipment through the rotary joint and is always in a vacuum state, and then the adsorption holes are sucked through the connecting pipe, air pipe and hollow shaft, so that the multiple adsorption holes on both sides generate a strong negative pressure to adsorb the bottom of both sides of the EPS packaging box.

[0035] Reference Figure 1-8 A multi-state size detection platform for EPS packaging molding materials includes a base 1, mounting frames 18 fixed on both sides of the base 1, and further includes:
[0036] The driving shaft 10 is rotatably connected to a mounting frame 18 on one side, and a plurality of connecting arms 12 are circumferentially fixedly installed on its end. A flippable placement plate 17 is installed at the end of the connecting arm 12. A mounting port is provided at the end of the connecting arm 12. A flip arm 26 is rotatably connected to the mounting port through a rotating shaft. The end of the flip arm 26 is fixedly connected to the end of the corresponding placement plate 17. A notch for adapting the flip arm 26 is provided at the opening of the sealed chamber 13. A flip mechanism that can drive the flip arm 26 to flip is also installed in the mounting port. The flip mechanism includes a driving assembly and a transmission assembly. The driving assembly is installed on the corresponding mounting frame 18, and the transmission assembly is installed in the mounting port. The driving shaft 10 can drive the EPS packaging box 16 in different states to rotate to the detection port 32.
[0037] Specifically, the transmission assembly includes a first gear 20 fixedly connected to the rotating shaft, and a first rack 19 meshing with the first gear 20 is slidably installed on the inner bottom of the mounting opening, and a guide cylinder 21 is fixed to the end side wall of the connecting arm 12. One end of the first rack 19 extends into the guide cylinder 21 and is elastically connected to a spring 22. The other end of the first rack 19 extends out of the mounting opening, and the driving assembly includes a first cylinder 5 fixedly mounted on the left mounting frame 18. The position of the first cylinder 5 corresponds to the detection port 32, and the other end of the first rack 19 is fixed with a counter plate 30 cooperating with the first cylinder 5. The first cylinder 5 is started to push the counter plate 30, and the first gear 20 and the rotating shaft are driven to rotate through the first rack 19, and then the placement plate 17 is driven to flip 90° through the flip arm 26. At this time, the laser emitted by the laser ranging head 4 on the right passes through the light-transmitting strip opening 27 for measurement, and the left side is measured normally, so that the height value of the EPS packaging box 16 can be obtained.
[0038] A turntable 28 is embedded on the placement plate 17, and a hollow shaft 25 is rotatably connected to the bottom of the placement plate 17. The upper end of the hollow shaft 25 is fixedly connected to the bottom of the turntable 28, and a second gear 24 is fixed on the hollow shaft 25. A second cylinder 6 is installed on the right mounting frame 18, and the telescopic end of the second cylinder 6 is fixedly connected to the second rack 7 that cooperates with the second gear 24. The position of the second cylinder 6 corresponds to the detection port 32. The hollow shaft 25 is a damping shaft. Start the second cylinder 6 to push the second rack 7, and drive the turntable 28 to rotate 90° through the second gear 24 and the hollow shaft 25. The same method can be used to measure the width value.
[0039] The two side surfaces of the turntable 28 are provided with multiple adsorption holes 29 for adsorbing the EPS packaging box 16. The bottom of the turntable 28 and the placement plate 17 are provided with corresponding light-transmitting strip openings 27. The multiple adsorption holes 29 are all connected to the hollow shaft 25. The lower end of the hollow shaft 25 is connected to the air pipe 23 through a rotating joint. The air pipe 23 is fixedly installed on the flip arm 26. A negative pressure pipe 11 is installed in the drive shaft 10. The negative pressure pipe 11 extends out of the end of the drive shaft 10. The air pipe 23 is connected to the negative pressure pipe 11 through a connecting pipe. The negative pressure pipe 11 is connected to the negative pressure equipment through a rotating joint and is always in an exhaust state. The adsorption holes 29 are then sucked through the connecting pipe, the air pipe 23 and the hollow shaft 25, so that the multiple adsorption holes 29 on both sides generate a strong negative pressure to adsorb the bottom of both sides of the EPS packaging box 16.
[0040] The left annular sealing cover 8 and the right annular sealing cover 9 are installed between a pair of mounting frames 18 and can be merged and separated. The facing surfaces of the left annular sealing cover 8 and the right annular sealing cover 9 are circumferentially provided with a plurality of relative sealing chambers 13, and the plurality of sealing chambers 13 are respectively a low-temperature chamber, a low-temperature humidification chamber, a high-temperature chamber, a high-temperature humidification chamber and a normal-temperature humidification chamber. The bottoms of the left annular sealing cover 8 and the right annular sealing cover 9 are provided with detection ports 32.
[0041] Furthermore, the multiple sealed chambers 13 of the right annular sealing cover 9 are all connected to the air inlet pipe 14. The air inlet pipes 14 corresponding to the low-temperature chamber, low-temperature humidification chamber, high-temperature chamber, high-temperature humidification chamber and normal-temperature humidification chamber respectively transport dry cold air, humidified cold air, dry hot air, humidified hot air and normal-temperature moisture. Multiple pairs of sealed chambers 13 are in a combined sealed state, and multiple EPS packaging boxes 16 are respectively in the low-temperature chamber, low-temperature humidification chamber, high-temperature chamber, high-temperature humidification chamber, normal-temperature humidification chamber and detection port 32. Dry cold air, humidified cold air, dry hot air, humidified hot air and normal-temperature moisture are respectively transported through the air inlet pipe 14, so that the EPS packaging boxes 16 reach different detection states respectively, and the detection process is integrated.
[0042] A pair of mounting frames 18 are fixed with mounting side plates 15 on the front and rear sides, and a horizontal double-headed hydraulic cylinder 31 is installed on the mounting side plates 15. The two telescopic ends of the double-headed hydraulic cylinder 31 are fixed with connecting plates, and the two connecting plates are respectively fixedly connected to the side walls of the left annular sealing cover 8 and the right annular sealing cover 9 for realizing merging and separation.
[0043] A pair of laser ranging heads 4 are respectively installed on the side walls of a pair of mounting frames 18 corresponding to the detection ports 32 facing each other. A processor 2 is installed on the base 1. The processor 2 is electrically connected to the pair of laser ranging heads 4 and is used to process the data of the laser ranging heads 4. The pair of laser ranging heads 4 simultaneously emit lasers to both ends of the EPS packaging box 16 to obtain two data. Since the distance between the pair of laser ranging heads 4 is constant, the subtraction of the two data is the length value of the EPS packaging box 16.
[0044] Furthermore, a vertical electric push rod 3 is mounted on the right side of the base 1. This push rod 3 is used to raise and lower the right laser rangefinder 4. The laser beam from the right laser rangefinder 4 passes through the light-transmitting strip opening 27. Activating the push rod 3 causes the laser rangefinder 4 to raise and lower the right side. The distance to the bottom of the EPS packaging box 16 is measured at different locations, generating multiple data points. By comparing the data differences, the flatness of the bottom of the EPS packaging box 16 can be determined. A smooth EPS packaging material provides better contact with the packaged product, providing uniform support and protection. An uneven surface can lead to localized pressure concentration, increasing the risk of product damage and compromising the aesthetics of the packaging.
[0045] Before the EPS packaging box 16 is placed, the left annular sealing cover 8 and the right annular sealing cover 9 are in a separated state. The EPS packaging box 16 is placed on multiple turntables 28 in sequence. Before placement, the negative pressure pipe 11 is connected to the negative pressure device through the rotary joint and is always in a vacuum state. Then, the suction holes 29 are sucked through the connecting pipe, the air pipe 23 and the hollow shaft 25, so that the multiple suction holes 29 on both sides generate a strong negative pressure to adsorb the bottom of both sides of the EPS packaging box 16. After multiple EPS packaging boxes 16 are placed, the double-head hydraulic system is started. The cylinder 31 drives the left annular sealing cover 8 and the right annular sealing cover 9 to move toward each other and merge through the connecting plate. The notch is adapted to the flip arm 26, so that multiple pairs of sealing chambers 13 are in a merged and sealed state. Multiple EPS packaging boxes 16 are respectively in the low-temperature chamber, low-temperature humidification chamber, high-temperature chamber, high-temperature humidification chamber, normal temperature humidification chamber and detection port 32. Dry cold air, humidified cold air, dry hot air, humidified hot air and normal temperature moisture are respectively transported through the air inlet pipe 14, so that the EPS packaging boxes 16 reach different detection states respectively, integrating the detection process.
[0046] The EPS packaging box 16 in a normal state in the detection port 32 can be detected first, and a pair of laser ranging heads 4 simultaneously emit lasers to both ends of the EPS packaging box 16 to obtain two data. Since the distance between the pair of laser ranging heads 4 is constant, the two data obtained by subtracting them are the length value of the EPS packaging box 16. The second cylinder 6 is started to push the second rack 7, and the turntable 28 is driven to rotate 90° through the second gear 24 and the hollow shaft 25. The width value can be measured by the same method. Then the first cylinder 5 is started to push the plate 30, and the first gear 20 and the rotating shaft are driven to rotate through the first rack 19, and then the placement plate 17 is driven to flip 90° through the flip arm 26. At this time, the laser emitted by the laser ranging head 4 on the right side passes through the light-transmitting strip opening 27 for measurement, and the left side is measured normally, so that the height value of the EPS packaging box 16 can be obtained. The EPS packaging boxes 16 in different states are turned to the detection port 32 in turn, and the automated size detection process in different states can be completed with high efficiency.
[0047] Since the light-transmitting strip opening 27 is arranged radially, the electric push rod 3 can be started to drive the right laser ranging head 4 to rise and fall, and the distance to the bottom of the EPS packaging box 16 can be measured at different positions. Multiple data can be obtained, and the flatness of the bottom of the EPS packaging box 16 can be detected by comparing the data difference.
[0048] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
