Description

Technical Field

[0001] The present invention belongs to the technical field of corrugated board detection, and specifically relates to a detection device for corrugated board processing. Background Art

[0002] A corrugated board is a multi-layer adhesive body, which is composed of at least one layer of corrugated core paper sandwich and two layers of paper panels. After production, the corrugated board needs to have high mechanical strength so that the corrugated board can withstand collisions and drops during the handling process after being made into a carton. Therefore, a certain number of samples need to be selected for strength detection after the corrugated board is produced.

[0003] In the prior art, the strength detection of corrugated board samples is mostly achieved by means of a pressure mechanism, that is, the corrugated board samples are manually placed under the pressure mechanism in sequence, and the edge of the corrugated board sample is clamped by means of a clamping mechanism. Subsequently, the pressure mechanism applies a predetermined pressure to the central position of the clamped corrugated board sample. If the corrugated board does not crack or crease under this pressure, it means that the strength of the cardboard sample meets the requirements. On the contrary, if the corrugated board cracks or creases under this pressure, it means that the strength of the cardboard sample does not meet the requirements. The above-mentioned strength detection method of corrugated board samples is relatively traditional, and the detection process requires too much manual intervention. If the number of cardboard samples is small, it is okay. However, once the number of cardboard samples is large, this detection method will affect the detection efficiency to a certain extent.

[0021] Please refer to Figure 1 and Figure 2, this embodiment provides a detection device for corrugated cardboard processing, including a bottom plate 10, a driving component 20, a horizontal pushing component 30, a first elastic pressing component 40, a pressing component 50, a vertical pushing component 60 and a second elastic pressing component 70. A support plate 101 is fixedly arranged on the upper part of the bottom plate 10. The vertical pushing component 60 is arranged on one side of the support plate 101 and is used to drive a plurality of vertically stacked corrugated cardboard to move upward intermittently. The horizontal pushing component 20 is arranged inside the support plate 101 and is used to horizontally push the topmost corrugated cardboard so that the topmost corrugated cardboard is misaligned with the lower corrugated cardboard. The pressing component 50 is arranged outside the vertical pushing component 60. The driving component 20 is installed on the side wall of the support plate 101 and is used to drive the pressing component 50 to rotate up and down. When the pressing component 50 rotates upward, it drives the misaligned topmost corrugated cardboard to stand upright inside the support plate 101. The first elastic pressing component 40 is installed on the inner wall of the support plate 101. The second elastic pressing component 70 is arranged on one side of the pressing component 50. After the topmost corrugated cardboard stands upright inside the support plate 101, the second elastic pressing component 70 cooperates with the first elastic pressing component 40 to press the edge of the corrugated cardboard, so that the pressing component 50 can smoothly apply pressure to the middle position of the corrugated cardboard.

[0022] When it is necessary to perform strength detection on several corrugated papers, several corrugated papers to be detected can be stacked vertically on the vertical pushing component 60. Subsequently, the horizontal pushing component 30 is used to horizontally push the topmost corrugated paper, so that the topmost corrugated paper is misaligned with the corrugated papers below. Then, the driving component 20 drives the pressing component 50 to rotate upward. When the pressing component 50 rotates upward, it acts on the bottom of the misaligned topmost corrugated paper, thereby driving the topmost corrugated paper to rotate. When the topmost corrugated paper rotates to the vertical state, it can enter the inner side of the support plate 101. At this time, the second elastic pressing component 70 presses the edge of the topmost corrugated paper against the first elastic pressing component 40 to realize the clamping and fixing of the topmost corrugated paper. Subsequently, the pressing component 50 continues to rotate to apply pressure to the central position of the topmost corrugated paper. After the pressing is completed, the first elastic pressing component 40 deforms and is misaligned with the second elastic pressing component 70. The pressing component 50 pushes the topmost corrugated paper and makes the topmost corrugated paper flip out from the other side of the support plate 101. Then, the driving component 20 drives the pressing component 50 to reverse downward, the vertical pushing component 60 drives the subsequent several corrugated papers to move up by the thickness of one paperboard, the horizontal pushing component 30 horizontally pushes the second topmost corrugated paper again, so that the second topmost corrugated paper is misaligned with the corrugated papers below again. Then, the driving component 20 drives the pressing component 50 to rotate upward again. The pressing component 50 acts on the bottom of the second topmost corrugated paper and drives the second topmost corrugated paper to rotate to the inner side of the support plate 101 and keep it in the vertical state. Subsequently, the second elastic pressing component 70 and the first elastic pressing component 40 cooperate again to clamp the edge of the second topmost corrugated paper again. The pressing component 50 applies pressure to the central position of the second topmost corrugated paper. Then, the first elastic pressing component 40 deforms again and is misaligned with the second elastic pressing component 70. The pressing component 50 pushes the second topmost corrugated paper to the other side of the support plate 101. In this way, through repeated cycles, the continuous and automatic detection of the strength of several corrugated papers can be realized.

[0023] Please refer to Figure 1 and Figure 2 In one embodiment, the driving component 20 includes a motor 201 and a rotating shaft 202. The motor 201 is fixedly installed on the side wall of the support plate 101. The rotating shaft 202 is arranged at the output end of the motor 201. The pressing component 50 includes a support rod 501, a pressing rod 502 and a pressing block 503. One end of the support rod 501 is fixedly connected to the rotating shaft 202, and the other end extends to the side of the vertical pushing component 60. The support rod 501 is perpendicular to the rotating shaft 202. The pressing rod 502 is fixedly installed at the end of the support rod 501 away from the rotating shaft 202. The pressing rod 502 is parallel to the rotating shaft 202. There are several groups of pressing blocks 503. Several pressing blocks 503 are fixedly arranged on the side wall of the pressing rod 502 and are distributed at intervals along the length direction of the pressing rod 502.

[0024] After the horizontal pushing component 30 pushes the top corrugated cardboard to make the top corrugated cardboard offset from the lower corrugated cardboard, a part of the offset top corrugated cardboard extends into the upward rotation path of the pressing rod 502. At this time, the motor 201 drives the rotating shaft 202 to rotate forward, thereby driving the support rod 501, the pressing rod 502 and a plurality of pressing blocks 503 to rotate upward. When the plurality of pressing blocks 503 rotate upward, they act on the bottom of the top corrugated cardboard, thereby pushing the top corrugated cardboard to gradually stand up. When the top corrugated cardboard rotates to the vertical state, it enters the inner side of the support plate 101. At this time, the second elastic pressing component 70 and the first elastic pressing component 40 cooperate to clamp the edge position of the top corrugated cardboard. After the top corrugated cardboard is clamped, as the rotating shaft 202 continues to rotate, the plurality of pressing blocks 503 act on the center position of the top corrugated cardboard, thereby pressing the top corrugated cardboard, so as to realize the strength detection of the top corrugated cardboard.

[0025] Please refer to Figure 3 , in one embodiment, the second elastic pressing component 70 includes a pressing wheel 701, a rotating rod 702, a fourth elastic member 704 and a second guide rod 705. The second guide rod 705 penetrates through the pressing rod 502 and is movably matched with the pressing rod 502. A stop block 703 is fixedly arranged on the second guide rod 705. One end of the fourth elastic member 705 is connected to the pressing rod 502, and the other end is connected to the stop block 703, which is used to provide elastic support for the second guide rod 705. The rotating rod 702 is fixedly arranged at one end of the second guide rod 705, and the pressing wheel 701 is rotatably arranged at one end of the rotating rod 702.

[0026] When the motor 201 drives the rotating shaft 202 to rotate forward, thereby driving the support rod 501, the pressing rod 502 and a plurality of pressing blocks 503 to rotate upward, the pressing rod 502 can drive the pressing wheel 701 to rotate upward synchronously through the second guide rod 705 and the rotating rod 702. The pressing wheel 701 acts on the bottom edge position of the uppermost corrugated board in advance, and then drives the uppermost corrugated board to gradually stand up. When the uppermost corrugated board stands inside the support board 101, the pressing wheel 701 presses the edge of the uppermost corrugated board against the first elastic pressing assembly 40 to clamp the uppermost corrugated board. As the rotating shaft 202 continues to rotate, the pressing wheel 701 is stressed and then drives the second guide rod 705 to move relative to the pressing rod 502 through the rotating rod 702, and the fourth elastic member 704 is stressed and compressed. A plurality of pressing blocks 503 on one side of the pressing rod 502 then act on the uppermost corrugated board, and then press the uppermost corrugated board to detect the strength of the corrugated board; through the above setting of the pressing wheel 701, when the uppermost corrugated board is pushed to stand up, the pressing wheel 701 can rotate relative to the rotating rod 702, and then adaptively roll along the bottom wall of the uppermost corrugated board, thereby reducing the friction force received by the uppermost corrugated board and preventing the friction force received by the uppermost corrugated board from being too large and then moving relative to the lower corrugated board, resulting in the uppermost corrugated board being unable to stand up smoothly.

[0027] Please refer to Figure 4 and Figure 5 , in one embodiment, the first elastic pressing assembly 40 includes a pressing block 401, a first guide rod 402 and a second elastic member 404. The first guide rod 402 penetrates through the support board 101 and is movably matched with the support board 101. The pressing block 401 is fixedly arranged at one end of the first guide rod 402 located inside the support board 101. One end of the second elastic member 404 is connected to the inner wall of the support board 101, and the other end is connected to the pressing block 401 for providing elastic support for the pressing block 401. A slope 403 is arranged on one side of the pressing block 401 away from the first guide rod 402.

[0028] After the pressing wheel 701 acts on the bottom wall of the corrugated cardboard and drives the corrugated cardboard to stand upright inside the support plate 101, the pressing wheel 701 can press the edge of the corrugated cardboard against the inclined surface 403 on one side of the pressing block 401, thereby realizing the clamping of the edge of the corrugated cardboard. As the rotating shaft 202 continues to rotate, the pressing rod 502 drives a plurality of pressing blocks 503 to act on the central position of the corrugated cardboard, and then presses the corrugated cardboard to realize the strength detection of the corrugated cardboard. During the strength detection of the corrugated cardboard, the pressing wheel 701 continuously presses against the inclined surface 403, thereby driving the pressing block 401 to continuously approach the inner wall direction of the support plate 101, causing the second guiding rod 402 to continuously move outward from the support plate 101, and at the same time causing the second elastic member 404 to be continuously compressed. When the inclined surface 403 on one side of the pressing block 401 is separated from the pressing wheel 701, the strength detection of the corrugated cardboard is completed. At this time, the pressing wheel 701 can push the corrugated cardboard so that the edge of the corrugated cardboard crosses over the pressing block 401, so that the corrugated cardboard after the strength detection is turned out from the other side of the support plate 101; after the current corrugated cardboard is turned out, the motor 201 drives the rotating shaft 202 to rotate in the reverse direction, and then drives the support rod 501, the pressing rod 502, a plurality of pressing blocks 503 and the pressing wheel 701 to rotate downward in reverse to realize the reset of the plurality of pressing blocks 503 and the pressing wheel 701. When the pressing wheel 701 rotates downward in reverse, the second elastic member 404 pushes the pressing block 401 to make the pressing block 401 away from the inner wall of the support plate 101, thereby realizing the reset of the pressing block 401.

[0029] Please refer to Figure 2 In one embodiment, an eccentric wheel 203 is further fixedly arranged on the rotating shaft 202. The transverse pushing assembly 30 includes a pushing plate 301, a first elastic member 302, a stop rod 303 and an extension rod 304. The pushing plate 301 is arranged inside the support plate 101 and can slide horizontally relative to the inner wall of the support plate 101. The stop rod 303 is arranged on one side of the pushing plate 301, and the end of the stop rod 303 is fixedly connected to the inner wall of the support plate 101. One end of the first elastic member 302 is connected to the stop rod 303, and the other end is connected to the pushing plate 301 for providing elastic support to the pushing plate 301. One end of the extension rod 304 is fixedly connected to the bottom wall of the pushing plate 301, and the other end extends to one side of the eccentric wheel 203 and is in contact with the circumferential side wall of the eccentric wheel 203.

[0030] When the motor 201 drives the rotating shaft 202 to rotate reversely, thereby driving the support rod 501, the pressing rod 502, several pressing blocks 503 and the pressing wheel 701 to rotate downward reversely, the rotating shaft 202 drives the eccentric wheel 203 to rotate synchronously reversely. At this time, the first elastic member 302 can push the push plate 301, causing the push plate 301 to slide horizontally along the inner wall of the support plate 101. When the pressing rod 502, several pressing blocks 503 and the pressing wheel 701 move to the position below the outer side of the uppermost corrugated cardboard, the push plate 301 can act on one side of the uppermost corrugated cardboard, thereby pushing the uppermost corrugated cardboard to cause a dislocation phenomenon between the uppermost corrugated cardboard and the lower corrugated cardboard. After the uppermost corrugated cardboard is dislocated, the motor 201 drives the rotating shaft 202 to rotate forward, thereby driving the eccentric wheel 203, the support rod 501, the pressing rod 502, several pressing blocks 503 and the pressing wheel 701 to rotate upward. At this time, the eccentric wheel 203 pushes the extension rod 304, thereby driving the push plate 301 to slide reversely along the inner wall of the support plate 101. The first elastic member 302 is compressed under force. When the push plate 301 slides reversely, it moves away from the uppermost corrugated cardboard, realizing the reset of the push plate 301.

[0031] Please refer to Figure 6 , in one embodiment, a slide rail 102 is fixedly arranged on the inner wall of the support plate 101, and a slider 305 that slides with the slide rail 102 is fixedly arranged on the side wall of the push plate 301.

[0032] Please refer to Figure 1 and Figure 7 , in one embodiment, the vertical pushing assembly 60 includes a lifting plate 601, a first telescopic rod 602, a first telescopic cylinder 603, a second telescopic rod 604, a second telescopic cylinder 605, a connecting pipe 606 and a third elastic member 608. The first telescopic cylinder 603 and the second telescopic cylinder 605 are fixedly installed on the upper part of the bottom plate 10. The lower end of the first telescopic rod 602 extends into the first telescopic cylinder 603 and is telescopically matched with the first telescopic cylinder 603, and the upper end extends above the first telescopic cylinder 603 and is fixedly connected with the lifting plate 601. The lower end of the second telescopic rod 604 extends into the second telescopic cylinder 605 and is telescopically matched with the second telescopic cylinder 605, and the upper end extends below the support rod 501. The third elastic member 608 is arranged inside the second telescopic cylinder 605 and is used to provide elastic support for the second telescopic rod 604. One end of the connecting pipe 606 is communicated with the inner cavity of the first telescopic cylinder 603, and the other end is communicated with the inner cavity of the second telescopic cylinder 605. An air supplement pipe 607 is further arranged on the side wall of the second telescopic cylinder 605. Check valves (not shown in the figure) are arranged inside both the air supplement pipe 607 and the connecting pipe 606.

[0033] When the motor 201 drives the rotating shaft 202 to rotate forward and backward, thereby driving the support rod 501 to rotate up and down, the support rod 501 can repeatedly press down the second telescopic rod 604. With the elastic support of the third elastic member 608 for the second telescopic rod 604, the second telescopic rod 604 can move up and down inside the second telescopic cylinder 605. When the second telescopic rod 604 moves down, the one-way valve inside the air supply pipe 607 closes, and the one-way valve inside the connecting pipe 606 opens. Then, the air inside the second telescopic cylinder 605 is pressed through the connecting pipe 606 into the first telescopic cylinder 603, thereby pushing the first telescopic rod 602, the lifting plate 601, and several corrugated papers on the upper part of the lifting plate 601 to move up by the thickness of one corrugated paper, so that several topmost corrugated papers are always at the height position where the pushing plate 301 is located. When the second telescopic rod 604 moves up, the one-way valve inside the air supply pipe 607 opens, and the one-way valve inside the connecting pipe 606 closes. Then, the outside air is drawn into the second telescopic cylinder 605 through the air supply pipe 607 to achieve air replenishment.

[0034] In one embodiment, the first elastic member 302, the second elastic member 404, the third elastic member 608, and the fourth elastic member 704 can be springs or metal shrapnel, and there is no limitation here.

[0035] In one embodiment, an air release pipe is further provided on the side wall of the first telescopic cylinder 603, and an air release valve is provided inside the air release pipe.

[0036] After all the corrugated papers on the upper part of the lifting plate 601 are detected, the staff can open the air release valve inside the air release pipe to release the air inside the first telescopic cylinder 603 through the air release pipe, so that the first telescopic rod 602 and the lifting plate 601 descend, thereby realizing the reset of the lifting plate 601 to continue to support several subsequent corrugated papers.

[0037] In one embodiment, the support plate 101 has a U-shaped frame structure.

[0038] In the embodiment of the present invention, when it is necessary to perform strength detection on several corrugated paperboards, several corrugated paperboards to be detected can be vertically stacked on the vertical pushing assembly 60. Subsequently, the horizontal pushing assembly 30 is used to horizontally push the topmost corrugated paperboard, so that the topmost corrugated paperboard is displaced relative to the lower corrugated paperboards. Then, the driving assembly 20 drives the pressing assembly 50 to rotate upward. When the pressing assembly 50 rotates upward, it acts on the bottom of the displaced topmost corrugated paperboard, thereby driving the topmost corrugated paperboard to rotate. When the topmost corrugated paperboard rotates to the vertical state, it can enter the inner side of the support plate 101. At this time, the second elastic pressing assembly 70 presses the edge of the topmost corrugated paperboard against the first elastic pressing assembly 40 to realize the clamping and fixing of the topmost corrugated paperboard. Subsequently, the pressing assembly 50 continues to rotate to apply pressure to the central position of the topmost corrugated paperboard. After the pressing is completed, the first elastic pressing assembly 40 deforms and is displaced from the second elastic pressing assembly 70. The pressing assembly 50 pushes the topmost corrugated paperboard and causes the topmost corrugated paperboard to flip out from the other side of the support plate 101. Then, the driving assembly 20 drives the pressing assembly 50 to rotate downward in reverse, and the vertical pushing assembly 60 drives the subsequent several corrugated paperboards to move up by the thickness of one paperboard. The horizontal pushing assembly 30 horizontally pushes the second topmost corrugated paperboard again, so that the second topmost corrugated paperboard is displaced relative to the lower corrugated paperboards again. Then, the driving assembly 20 drives the pressing assembly 50 to rotate upward again. The pressing assembly 50 acts on the bottom of the second topmost corrugated paperboard to drive the second topmost corrugated paperboard to rotate into the inner side of the support plate 101 and keep it in a vertical state. Subsequently, the second elastic pressing assembly 70 and the first elastic pressing assembly 40 cooperate again to clamp the edge of the second topmost corrugated paperboard again. The pressing assembly 50 applies pressure to the central position of the second topmost corrugated paperboard. Then, the first elastic pressing assembly 40 deforms again and is displaced from the second elastic pressing assembly 70. The pressing assembly 50 pushes the second topmost corrugated paperboard towards the other side of the support plate 101... Compared with the prior art, it can realize the continuous and automatic detection of the strength of several corrugated paperboards, and there is no need for too much manual intervention during the detection process, which has the advantages of good detection effect and high detection efficiency.

Within the scope of knowledge possessed by those of ordinary skill in the art, various changes can be made without departing from the purpose of the present invention.
