Description

Technical Field

[0001] The present invention relates to the technical field of corrugated cardboard pressing and forming processing, and specifically provides a corrugated cardboard pressing and forming processing method. Background Art

[0002] Corrugated cardboard is a multi-layer laminate composed of at least one layer of corrugated core paper sandwiched between and one layer of cardboard. It usually has relatively high mechanical strength and can withstand collisions and drops during handling. In the prior art, after corrugated cardboard is pressed and formed, it is usually necessary to detect its mechanical properties such as puncture resistance, tensile resistance, and edge compression resistance to ensure the quality of the formed corrugated cardboard.

[0003] However, the traditional methods for detecting the mechanical properties of corrugated cardboard have the following problems: 1. In the prior art, when detecting the mechanical properties such as puncture resistance, tensile resistance, and edge compression resistance of formed corrugated cardboard, since the equipment required for each detection is different, the number of equipment required for detecting multiple mechanical properties of formed corrugated cardboard is large and each piece of equipment needs to be operated separately, resulting in a large overall space occupied by the detection equipment, high overall space cost and equipment maintenance cost, and the overall steps of operating multiple pieces of equipment separately are cumbersome and the detection efficiency is low; 2. In the prior art, when detecting the mechanical properties of corrugated cardboard specimens through detection equipment, it is usually necessary to manually position the corrugated cardboard specimens during feeding and clean and discharge the damaged corrugated cardboard specimens later. When a large number of corrugated cardboard specimens need to be detected, it will result in a heavy overall operation burden on the manual labor, high labor cost, and low overall feeding and discharging efficiency of the corrugated cardboard specimens.

Detailed implementation manners

[0036] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0037] Please refer to Figure 1 , a corrugated cardboard pressing and forming processing method, which includes the following steps:

[0038] Step 1, raw material preparation: Prepare the face paper as the outer layer and the inner layer of the corrugated cardboard, and prepare the core paper for making the corrugated structure.

[0039] Step 2, corrugation forming: First, pass the heated core paper through corrugating rolls to press it into a corrugated shape, and then bond the face paper on both sides of the core paper with glue to form a double-sided corrugated cardboard.

[0040] Step 3, performance testing: Cut the formed corrugated cardboard into specimens required for testing. The specimen sizes corresponding to different mechanical properties are different, and use testing equipment to conduct mechanical tests on the corresponding specimens.

[0041] Step 4, transportation and storage: After all the mechanical property tests of the corrugated cardboard specimens are qualified, stack the formed corrugated cardboard and transport it to a dry and well-ventilated warehouse for storage.

[0042] Please refer to Figure 2 and Figure 3 In the above Step 3, a testing equipment is used to test multiple mechanical properties of the formed corrugated cardboard. The testing equipment includes a testing table 1. On the upper side of the testing table 1, a bursting strength mechanism 2, a tensile mechanism 3, and an edge crush mechanism 4 are sequentially arranged from left to right. A driving mechanism 5 for driving the bursting strength mechanism 2, the tensile mechanism 3, and the edge crush mechanism 4 is also arranged on the testing table 1.

[0043] Please refer to Figure 2 and Figure 3 The bursting strength mechanism 2 includes a first support table 21 and a second support table 23 fixedly arranged on the upper side of the testing table 1 front and back. An upper feeding assembly 22 is arranged on the upper side of the first support table 21. A first hole slot is opened on the second support table 23. A first testing assembly 24 is arranged above the second support table 23.

[0044] Please refer to Figure 4 The upper feeding assembly 22 includes a limiting frame 221 that moves back and forth. A rotating plate 222 is rotatably arranged on the lower side of the limiting frame 221. The right end of the limiting frame 221 is hinged to the right end of the lower rotating plate 222. A second hole slot that penetrates up and down is opened on the rotating plate 222. A first flat support plate 223 that moves left and right is arranged on the lower right side of the rotating plate 222. A first baffle plate 224 is fixedly arranged on the front side of the limiting frame 221. A first feeding box 225 fixedly connected to the testing table 1 through a left connecting frame 1 is arranged above the limiting frame 221. The lower end of the first feeding box 225 is aligned with the limiting frame 221. A first specimen 226 is arranged horizontally up and down in the first feeding box 225.

[0045] Please refer to Figure 4 The first testing assembly 24 includes a downward pressing rod 241 that moves up and down. A conical head 242 is fixedly arranged at the lower end of the downward pressing cylinder. A first pressure sensor is installed in the conical head 242. An elastic cover 243 is elastically slidably arranged on the outside of the conical head 242. A positioning plate 244 is fixedly arranged on the lower side of the elastic cover 243. A third hole slot for the conical head 242 to pass through is opened on the positioning plate 244.

[0046] When the puncture resistance of the formed corrugated cardboard is to be detected, under the drive of the drive mechanism 5, first align the lower end of the limit frame 221 with the lower end of the first blanking box 225. Then, the lowermost first sample 226 in the first blanking box 225 stably falls into the limit frame 221 under the action of gravity and fits on the upper surface of the rotating plate 222. At this time, the first support table 21 can limit the lower surface of the rotating plate 222 to prevent the rotating plate 222 from flipping downward. Then, move the first flat support plate 223 to the left to fit on the lower surface of the rotating plate 222 and also limit the rotating plate 222. Then, drive the limit frame 221 and the rotating plate 222 to drive the first sample 226 inside to move backward synchronously. The first flat support plate 223 moves backward synchronously and always limits the rotating plate 222. The first baffle plate 224 also moves backward synchronously and blocks and limits the remaining first samples 226 in the first blanking box 225 to prevent the first samples 226 from sliding downward from the first blanking box 225. As the limit frame 221 and the rotating plate 222 continue to move backward until the second hole groove on the rotating plate 222 is aligned with the first hole groove on the second support table 23 and the third hole groove on the positioning plate 244. At this time, drive the pressing rod 241 to drive the cone head 242 and the elastic cover 243 to move downward synchronously. The positioning plate 244 then presses and positions on the upper surface of the first sample 226 positioned in the limit frame 221. As the pressing rod 241 continues to move downward, the cone head 242 extends downward out of the third hole groove and applies a downward pressure on the upper surface of the first sample 226 until the cone head 242 completely punctures the first sample 226. Thus, the puncture resistance of the first sample 226 can be obtained through the first pressure sensor installed in the cone head 242. The first hole groove and the second hole groove can allow the cone head 242 to pass through to avoid damaging the cone head 242.

[0047] When the damaged first sample 226 is to be discharged, under the drive of the drive mechanism 5, move the rotating plate 222 forward until it disengages from the second support table 23. At this time, move the first flat support plate 223 to the right to release the limit on the rotating plate 222. The rotating plate 222 then rotates downward, and the first sample 226 inside the limit frame 221 automatically falls and is discharged under the action of gravity. When the discharging of the first sample 226 is completed, move the first flat support plate 223 to the left again to gradually contact the lower surface of the rotating plate 222 until it drives the rotating plate 222 to rotate upward again to return to the horizontal state. Finally, move the limit frame 221 and the rotating plate 222 forward to return to the upper side of the first support table 21. At this time, the lower end of the limit frame 221 is aligned with the lower end of the first blanking box 225 again. Then, the lowermost first sample 226 in the first blanking box 225 can stably fall into the limit frame 221 under the action of gravity and fit on the upper surface of the rotating plate 222.

[0048] Please refer to Figure 2 and Figure 3, the stretching mechanism 3 includes a bottom plate 31 fixedly arranged on the upper side of the detection table 1 from front to back and a fixing frame 33. On the upper side of the bottom plate 31, a second feeding component 32 is arranged. On the fixing frame 33, a second detection component 34 is arranged. A linkage component 35 is jointly arranged on the second feeding component 32 and the second detection component 34.

[0049] Please refer to Figure 5 , the second feeding component 32 includes an aggregate box 321 that moves back and forth. A through groove that penetrates up and down is formed in the aggregate box 321. An L-shaped baffle 322 is fixedly arranged at the upper end of the aggregate box 321. A U-shaped frame one 323 with an opening facing left is fixedly arranged on the right side of the aggregate box 321. Two rods are symmetrically arranged in the front and back on the U-shaped frame one 323 and slide. The left ends of the two rods symmetrically arranged in the front and back are jointly fixedly provided with a clamping plate one 324 that slides left and right through the aggregate box 321. The right ends of the two rods symmetrically arranged in the front and back are jointly fixedly provided with a connecting plate one 325. Above the aggregate box 321, there is a second feeding box 326 fixedly connected to the first feeding box 225 through a left connecting frame two. The bottom surface of the inner surface of the second feeding box 326 is an inclined surface, and the first discharge port on the second feeding box 326 is located at the lower end of the inclined surface. A second specimen 327 is arranged in the second feeding box 326 in a vertical and left-right manner along the inclined surface. On the lower side of the second feeding box 326 and symmetrically fixed on both sides of the first discharge port are two plate members.

[0050] Please refer to Figure 6 and Figure 7 , the second detection component 34 includes guide rods 341 symmetrically fixed on the fixing frame 33 from left to right. A clamping table 342 that moves up and down is jointly arranged and slides on the guide rods 341 symmetrically fixed on the left and right. A second pressure sensor is installed in the clamping table 342. A clamping plate two 343 is fixedly arranged on the front side of the clamping table 342. A guide rail 344 is fixedly arranged on the front side of the clamping table 342 and on the right side of the clamping plate two 343. A clamping plate three 345 that moves left and right slides on the guide rail 344. A T-shaped sliding column 346 is fixedly arranged on the right side of the clamping plate three 345. A first rack 347 is fixedly arranged on the rear side of the clamping table 342. On the rear side of the fixing frame 33 and behind the first rack 347, a gear 348 meshing with the first rack 347 is rotatably arranged through a support one. A second rack 349 that moves up and down is meshed and connected to the rear side of the gear 348.

[0051] Please refer to Figure 5 , Figure 6 and Figure 7, the linkage assembly 35 includes an L-shaped bracket 351 fixedly arranged on the right side of the first connecting plate 325. The upper end of the vertical section of the L-shaped bracket 351 is fixedly provided with a first wedge block 352 with an inclined surface at the rear end. The right side of the fixed bracket 33 is elastically and slidably provided with a first spring rod 353 symmetrically up and down through a second support. The right ends of the symmetrically arranged first spring rods 353 up and down are fixedly provided with a second wedge block 354 with an inclined surface at the front side. The left ends of the symmetrically arranged first spring rods 353 up and down are fixedly provided with a limiting platform 355. A linear groove 356 slidably connected to the T-shaped sliding column 346 is opened on the left side of the limiting platform 355. Among them, anti-friction balls are symmetrically arranged in the front and rear directions on the contact surface between the third clamping plate 345 and the limiting platform 355 to reduce the friction force.

[0052] When the anti-tensile performance of the formed corrugated cardboard needs to be detected, under the drive of the drive mechanism 5, first move the aggregate box 321 to the upper side of the bottom plate 31, and align the through groove inside the aggregate box 321 with the first discharge port of the second discharge box 326. The leftmost second sample 327 in the second discharge box 326 then falls into the aggregate box 321 and is supported by the bottom plate 31 below it. The remaining second samples 327 in the second discharge box 326 will then slide synchronously to the left along the inclined surface at the bottom of the second discharge box 326 to make up the position. Then, drive the first connecting plate 325 to drive the first clamping plate 324 to move leftward through the second rod until the lower end of the second sample 327 in the aggregate box 321 is clamped and fixed. The L-shaped bracket 351 synchronously drives the first wedge block 352 to move leftward by a certain distance and aligns the inclined surface at the rear end of the first wedge block 352 with the inclined surface at the front end of the second wedge block 354. Then, drive the aggregate box 321 to drive the second sample 327 inside it to move backward between the second clamping plate 343 and the third clamping plate 345. The L-shaped baffle 322 synchronously moves backward and closes the first discharge port on the second discharge box 326. The first wedge block 352 also synchronously moves backward and drives the limiting platform 355 and the third clamping plate 345 to move leftward along the guide rail 344 through the pressing cooperation with the second wedge block 354, so that when the second sample 327 inside the aggregate box 321 moves between the second clamping plate 343 and the third clamping plate 345, its upper end is just clamped and fixed. At this time, move the second rack 349 downward to engage with the gear 348 for transmission. The gear 348 also simultaneously engages with the first rack 347 for transmission. The first rack 347 drives the clamping table 342 to move upward along the guide rod 341 and applies an upward pulling force to the clamped second sample 327 through the second clamping plate 343 and the third clamping plate 345 until the second sample 327 is completely broken. Thus, the anti-tensile performance of the second sample 327 can be obtained through the second pressure sensor installed in the clamping table 342. Among them, when the third clamping plate 345 moves upward, the T-shaped sliding column 346 synchronously moves upward along the linear groove 356, and the friction resistance between the third clamping plate 345 and the limiting platform 355 can be reduced by the anti-friction balls.

[0053] When blanking the damaged specimen two 327, move the aggregate box 321 forward. Consequently, the first wedge block 352 disengages from the second wedge block 354, and the limiting platform 355 moves to the right to reset under the action of the first spring rod 353. Simultaneously, it drives the T-shaped sliding column 346 and the third clamping plate 345 to move to the right along the guide rail 344 to release the clamping of the upper half of the damaged specimen two 327, enabling this part to automatically fall for blanking. Then, move the first clamping plate 324 to the right to release the clamping of the lower half of the damaged specimen two 327 in the aggregate box 321, allowing this part to automatically slide down and fall from the lower end of the aggregate box 321. After completing the blanking of the specimen two 327, move the aggregate box 321 forward again until it aligns with the first blanking port. The leftmost specimen two 327 in the second blanking box 326 then falls into the aggregate box 321. Since the first clamping plate 324 and the first flat supporting plate 223 move synchronously, and the first flat supporting plate 223 needs to move to the left again before the rotating plate 222 moves forward and resets to the upper side of the first supporting platform 21 to press and reset the downwardly flipped rotating plate 222, the first clamping plate 324 is at the leftmost end and inside the aggregate box 321 at this time. Finally, after the horizontally positioned rotating plate 222 resets to the upper side of the first supporting platform 21, move the first flat supporting plate 223 and the first clamping plate 324 synchronously to the right, causing the first clamping plate 324 to move out of the aggregate box 321. At this time, the specimen two 327 that has fallen into the aggregate box 321 continues to fall until it is supported by the bottom plate 31 below it.

[0054] Please refer to Figure 2 and Figure 8 As shown in FIGS. and, the edge pressing mechanism 4 includes a third feeding component 41 and a limiting component 42 arranged on the upper side of the detection table 1, and a pressing plate 43 that moves up and down behind the third feeding component 41 and the limiting component 42. A third pressure sensor is installed inside the pressing plate 43.

[0055] Please refer to Figure 8 and Figure 9, the feeding component three 41 includes a U-shaped frame two 411 that moves back and forth and has an opening facing right. A fixed platform one 412 is fixedly arranged on the upper side of the U-shaped frame two 411. Spring rods two 413 are symmetrically and elastically slidably arranged on the fixed platform one 412 in the front and back directions. The right ends of the front and back symmetric spring rods two 413 are jointly fixedly provided with a side baffle one 414. A baffle plate two 415 is fixedly arranged on the front side of the U-shaped frame two 411. The baffle plate two 415 is composed of an inclined plate at the rear and a horizontal plate at the front. Above the U-shaped frame two 411, there is a feeding box three 416 fixedly connected to the feeding box two 326 through a left connecting frame three. The right side of the feeding box three 416 is fixedly connected to the detection table 1 through a connecting frame four. The bottom surface of the inner surface of the feeding box three 416 is an inclined surface, and the second feeding port on the feeding box three 416 is located at the lower end of the inclined surface. A sample three 417 is arranged in the feeding box three 416 in a vertical and left-right arrangement along the inclined surface. On the lower side of the feeding box three 416 and symmetrically fixedly arranged on both sides of the second feeding port are plate members three.

[0056] Please refer to Figure 8 and Figure 9 , the limiting component 42 includes a fixed platform two 421 fixedly arranged on the upper side of the detection table 1 and located on the right side of the U-shaped frame two 411. Spring rods three 422 are symmetrically and elastically slidably arranged on the fixed platform two 421 in the front and back directions. The right ends of the front and back symmetric spring rods three 422 are jointly fixedly provided with an L-shaped support plate 423 located under the U-shaped frame two 411. The rear end of the horizontal section of the L-shaped support plate 423 is an inclined surface. A side baffle two 424 that moves left and right is arranged on the right side of the L-shaped support plate 423 and the U-shaped frame two 411. A flat support plate two 425 located under the U-shaped frame two 411 is fixedly arranged on the left side of the side baffle two 424.

[0057] When detecting the edge compressive performance of the formed corrugated cardboard, driven by the driving mechanism 5, first move the second U-shaped frame 411 to the upper side of the horizontal section of the L-shaped support plate 423, and align the second U-shaped frame 411 with the second material discharge port of the third material discharge box 416. The leftmost sample three 417 in the third material discharge box 416 then falls into the inner side of the second U-shaped frame 411 and is supported by the L-shaped support plate 423 below it. The remaining samples three 417 in the third material discharge box 416 will then slide synchronously to the left along the inclined plane at the bottom of the third material discharge box 416 to fill the position. Next, move the second side baffle 424 to the left to fit the sample three 417 inside the second U-shaped frame 411, and make the second side baffle 424 and the first side baffle 414 only limit the left and right positions of the sample three 417 instead of tightly fitting and clamping it, so as to avoid the clamping force of the second side baffle 424 and the first side baffle 414 affecting the final detection result of the edge compressive performance of the sample three 417. The second flat support plate 425 then moves synchronously to the left and pushes the L-shaped support plate 423 to the left until the second flat support plate 425 replaces the L-shaped support plate 423 to support the sample three 417. Then, drive the second U-shaped frame 411 and the second flat support plate 425 to move the sample three 417 backward synchronously until the sample three 417 is directly below the pressing plate 43. The second material blocking plate 415 then closes the second material discharge port through the front horizontal plate. At this time, move the pressing plate 43 downward to apply a downward pressure to the upper edge of the sample three 417 until a significant deformation is pressed out on the upper edge of the sample three 417, so that the edge compressive performance of the sample three 417 can be obtained through the third pressure sensor installed in the pressing plate 43. Among them, the first side baffle 414 can displace to the left through the third spring rod 422 to avoid hindering the compressive deformation of the sample three 417, thus ensuring the accuracy of the detection result of the edge compressive performance of the sample three 417.

[0058] When discharging the damaged sample three 417, move the second side baffle 424 and the second flat support plate 425 synchronously to the right until the second flat support plate 425 no longer supports the sample three 417, and the sample three 417 then automatically falls and discharges. When the discharging of the sample three 417 is completed, move the second U-shaped frame 411 and the second side baffle 424 forward again to reset. Since the second side baffle 424 and the second flat support plate 425 also move synchronously with the first flat support plate 223, the second flat support plate 425 is also at the leftmost end at this time. And at this time, the L-shaped support plate 423 is reset to the rightmost end under the action of the third spring rod 422. The forward-moving second flat support plate 425 then cooperates with the inclined plane at the rear end of the horizontal section of the L-shaped support plate 423, so that the L-shaped support plate 423 moves to the left again. Finally, move the first flat support plate 223 and the second flat support plate 425 synchronously to the right. At this time, the second U-shaped frame 411 is aligned with the second material discharge port, and the leftmost sample three 417 in the third material discharge box 416 falls into the inner side of the second U-shaped frame 411 and is supported by the L-shaped support plate 423.

[0059] Please refer toFigure 2 and Figure 3 The driving mechanism 5 includes a first driving component 51 and a second driving component 52 which are arranged front and back on the detection table 1.

[0060] Please refer to Figure 2 、 Figure 4 、 Figure 5 、 Figure 8 and Figure 9 The first driving component 51 includes a pneumatic cylinder 511 fixedly arranged on the lower side of the detection table 1 through a third support. The telescopic end of the pneumatic cylinder 511 is fixedly provided with a connecting plate 512 that moves back and forth through a fourth plate member. On the rear side of the connecting plate 512, a third rod connecting the connecting limit frame 221, a fourth rod connecting the aggregate box 321, and a fifth rod connecting the second U-shaped frame 411 are fixedly arranged in sequence from left to right. On the right side of the connecting plate 512, a third connecting plate 513 is fixedly arranged. On the right side of the third connecting plate 513, a pneumatic cylinder 514 is fixedly arranged. The telescopic end of the pneumatic cylinder 514 is fixedly provided with a connecting plate 515 that moves left and right. The left side of the connecting plate 515 is fixedly connected to the second side baffle 424 through symmetric front and rear sixth rods. The front side of the connecting plate 515 is fixedly provided with a first straight connecting rod 516 to fixedly arrange a total connecting rod 517 that extends left and right. On the rear side of the total connecting rod 517, a second straight connecting rod 518 fixedly connected to the front end of the first connecting plate 325 and an L-shaped connecting rod 519 fixedly connected to the front end of the first flat support plate 223 are fixedly arranged in sequence from right to left.

[0061] Please refer to Figure 3 、 Figure 4 and Figure 7 The second driving component 52 includes a third U-shaped frame 521 fixedly arranged on the upper side of the detection table 1 with an opening facing downwards. On the upper side of the horizontal section of the third U-shaped frame 521, a pneumatic cylinder 522 is fixedly arranged. The telescopic end of the pneumatic cylinder 522 is fixedly provided with a connecting plate 523 that moves up and down. The right end of the connecting plate 523 is fixedly connected to the pressing plate 43 through a seventh rod. The left end of the connecting plate 523 is fixedly connected to the upper end of the lower pressing rod 241. On the rear side of the connecting plate 523, a sixth connecting plate 524 is fixedly arranged. The rear end of the sixth connecting plate 524 is fixedly connected to the second rack 349 through an eighth rod.

[0062] When corresponding tests need to be carried out on different corrugated cardboard specimens synchronously, first, the air cylinder 511 drives the connecting plate 512 to move to the forefront. At this time, the specimen 226 at the lowermost side in the blanking box 225 falls into the limiting frame 221 and fits on the upper surface of the rotating plate 222. The specimen 227 at the leftmost side in the blanking box 326 falls into the aggregate box 321 and is supported by the bottom plate 31 below it. The specimen 227 at the leftmost side in the blanking box 416 falls into the inner side of the U-shaped frame 411 and is supported by the L-shaped support plate 423 below it. Then, the air cylinder 514 drives the connecting plate 515 to move leftward. The connecting plate 515 drives the side baffle 424 and the straight connecting rod 516 to move leftward accordingly. The main connecting rod 517 drives the connecting plate 325 and the flat support plate 223 to move leftward synchronously through the straight connecting rod 518 and the L-shaped connecting rod 519 respectively, so that the flat support plate 425 supports the specimen 417, the clamping plate 324 clamps the specimen 327, and the flat support plate 223 limits the rotating plate 222. Then, the air cylinder 511 drives the connecting plate 512 to move to the rearmost end, aligning the hole groove 2 with the hole groove 1 and the hole groove 3, enabling the clamping plate 343 and the clamping plate 345 to clamp the upper end of the specimen 327, and making the specimen 417 located below the pressing plate 43. Then, the air cylinder 522 drives the pressing rod 241, the rack 349, and the pressing plate 43 to move downward synchronously until all the corresponding specimens 226, 327, and 417 are damaged and the corresponding mechanical property test results are obtained. The above detection method can realize the synchronous detection of multiple mechanical properties such as puncture resistance, tensile resistance, and edge compression resistance of corrugated cardboard by one device, reducing the number of detection devices and the space occupied by the overall equipment, thus reducing the overall space cost and the maintenance cost of the equipment, and greatly simplifying the operation steps required for multiple detections, improving the overall detection efficiency of corrugated cardboard.

[0063] When cutting materials for different damaged corrugated cardboard specimens, first, the air cylinder 511 drives the limit frame 221, the aggregate box 321, and the U-shaped frame II 411 to move forward, and the air cylinder 514 drives the flat support plate I 223, the clamping plate I 324, and the flat support plate II 425 to move to the right, so as to synchronously cut the materials of the damaged specimen I 226, specimen II 327, and specimen III 417. Then, the air cylinder 514 drives the flat support plate I 223 to move to the left to limit the rotating plate 222, and the clamping plate I 324 and the flat support plate II 425 move to the left synchronously. Then, the air cylinder 511 drives the limit frame 221, the aggregate box 321, and the U-shaped frame II 411 to move forward and reset to the front end. Finally, the air cylinder 514 drives the flat support plate I 223, the clamping plate I 324, and the flat support plate II 425 to move to the right and reset again. At this time, the lowermost specimen I 226 in the material cutting box I 225 falls into the limit frame 221 and fits on the upper surface of the rotating plate 222, the leftmost specimen II 327 in the material cutting box II 326 falls into the aggregate box 321 and is supported by the bottom plate 31 below it, and the leftmost specimen III 417 in the material cutting box III 416 falls into the inner side of the U-shaped frame II 411 and is supported by the L-shaped support plate 423 below it. The above operation method can realize the synchronous automatic feeding and stable positioning of the corrugated cardboard specimens required for various mechanical property tests, and can automatically clean and cut the materials uniformly after the damage of each corrugated cardboard specimen. Therefore, when detecting a large number of corrugated cardboard specimens, the overall burden of manual operation is greatly reduced, the labor cost is reduced, and the efficiency of the overall feeding and cutting of the corrugated cardboard specimens is improved.
