[0046] See also Figure 1 、 Figure 2 as well as Figure 3, this embodiment provides a cardboard cutting device for producing medicine packaging boxes, including side panels 10, a storage box 20, a conveyor belt 30, a horizontal pushing assembly 40, a barrier assembly 50, an elastic pushing assembly 60, a vertical pushing assembly 70 and a driving assembly 80. The side panels 10 are provided with two groups, and the two groups of side panels 10 are relatively distributed. The conveyor belt 30 is arranged between the two groups of side panels 10. The storage box 20 is arranged at the left end position above the conveyor belt 30 for storing a plurality of cardboards. The upper and right sides of the storage box 20 are both open. The elastic pushing assembly 60 is arranged inside the storage box 20 for applying a rightward thrust to a plurality of cardboards. The vertical pushing assembly 70 is arranged below the storage box 20 for The cardboard at the rightmost position is pushed up so that the upper end of the rightmost cardboard is misaligned with the rest of the cardboards. The horizontal pushing assembly 40 is arranged at the right end position above the storage box 20. After the rightmost cardboard is pushed up, the horizontal pushing assembly 40 is used to push the rightmost cardboard horizontally so that the rightmost cardboard is dumped onto the conveyor belt 30, and then the conveyor belt 30 transports the cardboard to the cutting station. The barrier assembly 50 is arranged on the right side of the storage box 20 for blocking several cardboards. The drive assembly 80 is installed below the storage box 20. When the vertical pushing assembly 70 pushes up the rightmost cardboard, the drive assembly 80 is used to drive the barrier assembly 50 to be removed from the right side of the storage box 20, thereby releasing the blocking state of the cardboard.

[0047] When it is necessary to cut the cardboards continuously, several cardboards with cut sheets can be placed inside the storage box 20, so that the cardboards are vertically distributed in sequence along the length direction of the storage box 20, and then the elastic pushing assembly 60 applies a rightward thrust to the cardboards so that the cardboards are pressed against the barrier assembly 50, and then the vertical pushing assembly 70 and the horizontal pushing assembly 40 are started. The vertical pushing assembly 70 continuously pushes up the cardboard at the rightmost position so that the upper end of the rightmost cardboard is misaligned with the other cardboards, and the horizontal pushing assembly 40 continuously pushes the dislocated rightmost cardboard horizontally so that the cardboards are continuously dumped onto the conveyor belt 30 , and then the conveyor belt 30 continuously transports the cardboard to the cutting station, and then is cut and continuously cut; when the vertical pushing component 70 continuously pushes up the rightmost cardboard, the driving component 80 drives the blocking component 50 to move, thereby releasing the blocking state of the cardboard, so that when the horizontal pushing component 40 pushes the dislocated cardboard horizontally, the cardboard can be smoothly dumped onto the conveyor belt 30, and as the vertical pushing component 70 and the horizontal pushing component 40 continuously push the rightmost cardboard, the subsequent cardboard continues to move to the right along the inside of the storage box 20 under the action of the elastic pushing component 60, thereby realizing automatic supply of cardboard.

[0048] See also Figure 2In one embodiment, the elastic pushing assembly 60 includes a pushing block 601 and a second elastic member 602. The pushing block 601 is movably arranged inside the storage box 20. One end of the second elastic member 602 is connected to the left side wall inside the storage box 20, and the other end is connected to the pushing block 601, which is used to provide elastic support for the pushing block 601.

[0049] Initially, the staff can push the push block 601 to compress the second elastic member 602, and then place several cardboards to be cut inside the storage box 20 to the right of the push block 601, so that the cardboards are vertically distributed in sequence along the length direction of the storage box 20, and then release the push block 601. The second elastic member 602 pushes the push block 601 to move to the right along the inside of the storage box 20, and the push block 601 acts on the leftmost cardboard, thereby pressing the cardboards against one side of the barrier assembly 50.

[0050] See also Figure 3 as well as Figure 7 In one embodiment, a second support 206 is fixedly provided on the bottom wall of the storage box 20, and the vertical pushing assembly 70 includes a motor 701, a rotating shaft 702 and a push rod 704. The rotating shaft 702 passes through the second support 206 and rotates with the second support 206. The motor 701 is fixedly installed at the bottom of the storage box 20, and the output shaft of the motor 701 is connected to the rotating shaft 702. The push rod 704 is fixedly provided on the side wall of the rotating shaft 702 and is perpendicular to the rotating shaft 702. A slot 205 is provided on the right side of the bottom of the storage box 20 for the push rod 704 to extend into the inner side of the storage box 20.

[0051] After the push block 601 presses several cardboards against one side of the barrier assembly 50, the motor 701 is started, and the motor 701 drives the rotating shaft 702 to rotate, thereby driving the push rod 704 to rotate. When the push rod 704 rotates, it enters the storage box 20 from the slot 205, and then acts on the bottom of the rightmost cardboard to push the rightmost cardboard upward, so that the rightmost cardboard moves up compared to the other cardboards. When the rightmost cardboard moves up, its upper end is misaligned with the other cardboards, and then the horizontal pushing assembly 40 pushes horizontally for the upper end of the rightmost cardboard, so that the rightmost cardboard is dumped onto the conveyor belt 30, and then is transported to the cutting station by the conveyor belt 30 to realize the cutting of the cardboard; after the current rightmost cardboard is pushed horizontally onto the conveyor belt 30, as the rotating shaft 702 continues to move, Continuing to rotate, the push rod 704 rotates out from the inside of the storage box 20, and the second elastic member 602 pushes the push block 601 to move right along the inside of the storage box 20, thereby pushing several subsequent cardboards to move right, and the subsequent rightmost cardboard is again pressed to the side of the barrier component 50, and then the push rod 704 is rotated from the slot 205 into the storage box 20 again to push the subsequent rightmost cardboard up again, so that the upper end of the subsequent rightmost cardboard is again misaligned with the other cardboards, and then the horizontal pushing component 40 pushes the subsequent rightmost cardboard horizontally again, so that the subsequent rightmost cardboard is dumped onto the conveyor belt 30 again, and then is transported to the cutting station again by the conveyor belt 30... Such a reciprocating cycle can realize continuous automatic transportation and continuous automatic cutting of several cardboards.

[0052] See also Figure 5 as well as Figure 7 In one embodiment, the baffle assembly 50 includes an L-shaped baffle 501 and a guide rod 502. One end of the L-shaped baffle 501 extends to the right side of the storage box 20, and the other end extends to the front side of the storage box 20. One end of the guide rod 502 is fixedly connected to the outer wall of the storage box 20, and the other end passes through the L-shaped baffle 501 and movably cooperates with the L-shaped baffle 501. An end block 504 is fixedly provided on the end of the guide rod 502 away from the storage box 20. The end block 504 is connected to the L-shaped baffle 50 1 are connected by a first elastic member 503, and the first elastic member 503 is used to provide elastic support for the L-shaped baffle 501. The driving assembly 80 includes a second rack rod 801 and an incomplete gear 802, and the incomplete gear 802 is fixedly arranged on the outside of the rotating shaft 702. One end of the second rack rod 801 extends to one side of the incomplete gear 802 and can engage with the incomplete gear 802, and the other end extends to the front side of the storage box 20 and is fixedly connected to the L-shaped baffle 501.

[0053] When the second elastic member 602 applies an elastic supporting force to the push block 601, the push block 601 presses several cardboards against the side wall of the L-shaped baffle 501 to limit the position of several cardboards. When the motor 701 drives the rotating shaft 702 to rotate and then drives the push rod 704 to rotate to push the rightmost cardboard upward, the rotating shaft 702 can also drive the incomplete gear 802 to rotate, and the meshing action of the incomplete gear 802 and the second rack rod 801 drives the second rack rod 801 to move. When the second rack rod 801 moves, it pulls the L-shaped baffle 501, so that the L-shaped baffle 501 moves. When the L-shaped baffle 501 moves, it drives the first elastic member 503 to be compressed. When the push rod 704 moves, the L-shaped baffle 501 moves. After 704 has pushed up the rightmost cardboard, one end of the L-shaped baffle 501 is removed from the right side of the storage box 20, thereby releasing the blocking state for the cardboard. At this time, the horizontal pushing component 40 pushes the rightmost cardboard horizontally, so that the rightmost cardboard is smoothly dumped onto the conveyor belt 30; when the rightmost cardboard is dumped onto the conveyor belt 30, the push rod 704 rotates out from the inside of the storage box 20, the incomplete gear 802 is disengaged from the second rack rod 801, and the first elastic member 503 pushes the L-shaped baffle 501 to make the L-shaped baffle 501 move in the opposite direction. When the L-shaped baffle 501 moves in the opposite direction, one end thereof re-extends to the right side of the storage box 20 to continue to block the subsequent cardboards.

[0054] See also Figure 4 as well as Figure 5 In one embodiment, a support plate 201 is fixedly provided on the upper part of the storage box 20, and a first support 203 is fixedly provided on the upper part of the support plate 201. The horizontal pushing assembly 40 includes a gear 401, a threaded sleeve 402, a first rack rod 403 and a screw 404. The threaded sleeve 402 is rotatably set on one side of the first support 203, one end of the screw 404 extends to the inside of the threaded sleeve 402 and is threadedly engaged with the threaded sleeve 402, and the other end extends to the outside of the threaded sleeve 402. The gear 401 is fixedly provided on the outside of the threaded sleeve 402, one end of the first rack rod 403 extends to one side of the gear 401 and meshes with the gear 401, and the other end extends to the front side of the storage box 20 and is fixedly connected to the second rack rod 801.

[0055] When the incomplete gear 802 is engaged with the second rack rod 801 and thus drives the second rack rod 801 to move, the second rack rod 801 drives the L-shaped baffle 501 to move, so that the L-shaped baffle 501 is removed from the right side of the storage box 20 to release the blocking state of the cardboard. On the other hand, the second rack rod 801 drives the first rack rod 403 to move, and the meshing action of the first rack rod 403 and the gear 401 drives the threaded sleeve 402 to rotate. When the threaded sleeve 402 rotates, it cooperates with the thread of the screw 404 and drives the screw 404 to move to the outside of the threaded sleeve 402, thereby targeting the dislocated rightmost cardboard. The first gear 403 is engaged with the second rack rod 801 and the second rack rod 403 is engaged with the second rack rod 801, and the first gear 403 is engaged with the second rack rod 801 and the second rack rod 403. When the first rack rod 403 moves in the opposite direction, it engages with the gear 401 in the opposite direction and drives the threaded sleeve 402 to rotate in the opposite direction. The reverse thread of the threaded sleeve 402 and the screw rod 404 cooperate to drive the screw rod 404 to move toward the inside of the threaded sleeve 402, thereby resetting the screw rod 404.

[0056] See also Figure 4 In one embodiment, a guide rail 202 is fixedly provided on the upper portion of the support plate 201 , and a slider 405 is fixedly provided on the bottom of the screw rod 404 , and the slider 405 is slidably engaged with the guide rail 202 .

[0057] Through the sliding cooperation between the slider 405 and the guide rail 202, the threaded sleeve 402 can smoothly drive the screw 404 to move when rotating, thereby smoothly pushing the dislocated rightmost cardboard horizontally.

[0058] When the push rod 704 rotates into the inner side of the storage box 20 to push the rightmost cardboard upward, the cardboards are in a compressed state, so the rightmost cardboard is difficult to be pushed upward smoothly, which makes it difficult for the rightmost cardboard to be misaligned with the other cardboards and thus cannot be pushed horizontally smoothly. Figure 3 as well as Figure 6 In one embodiment, a slide groove 204 is provided at the bottom of the storage box 20 along the length direction, and the slide groove 204 is located above the rotating shaft 702 and parallel to the rotating shaft 702. An extension rod 603 is fixedly provided at the bottom of the push block 601, and the extension rod 603 extends from the slide groove 204 to the bottom of the storage box 20. A plurality of oblique push bars 703 are fixedly provided on the side wall of the rotating shaft 702, and the plurality of oblique push bars 703 are distributed in sequence along the length direction of the rotating shaft 702.

[0059] When the rotating shaft 702 drives the push rod 704 to rotate so that the push rod 704 rotates into the storage box 20 to push the rightmost cardboard upward, the oblique push strip 703 outside the rotating shaft 702 can act on the extension rod 603 as the rotating shaft 702 rotates, so that the extension rod 603 is pushed and drives the push block 601 to move left along the storage box 20. When the push block 601 moves left, the pressing state of the cardboard can be released, thereby ensuring that the rightmost cardboard can be smoothly pushed by the push rod 704, and then smoothly moved up and aligned with it. The remaining cardboards are smoothly dislocated, and when the push block 601 moves to the left, the compressed state of several cardboards is released, so that several subsequent cardboards will not be removed from the right side of the storage box 20 due to the L-shaped baffle 501 being removed from the right side of the storage box 20 and then pressed out from the right end of the storage box 20, thereby ensuring the orderly transportation of the cardboards; after the rightmost cardboard is smoothly pushed up, the extension rod 603 slides away from one end of the oblique push bar 703, and at this time the second elastic member 602 pushes the push block 601, causing the push block 601 to move right along the inside of the storage box 20 to re-compress the several cardboards.

[0060] In one embodiment, the oblique push bar 703 has a spiral structure.

[0061] In one embodiment, the first elastic member 503 and the second elastic member 602 may be springs or metal springs, which are not limited here.

[0062] See also Figure 1 as well as Figure 2 In one embodiment, a plurality of bracket plates 101 are fixedly provided on the upper portion of the side plate 10 , and the plurality of bracket plates 101 extend to the side of the storage box 20 and are fixedly connected to the storage box 20 to provide support for the storage box 20 .

[0063] The working principle of the present invention is as follows:

[0064] First, the staff pushes the push block 601 so that the push block 601 is located near the left side of the storage box 20. At this time, the second elastic member 602 is compressed. Then, several cardboards are placed in the storage box 20 at the right side of the push block 601, so that the cardboards are vertically distributed in sequence along the length direction of the storage box 20. Then, the staff releases the push block 601, and the second elastic member 602 pushes the push block 601 to move to the right. The push block 601 acts on the leftmost cardboard, thereby pressing the cardboards against the side wall of the L-shaped baffle 501. Then, the motor 701 is started. 1 drives the rotating shaft 702 to rotate, thereby driving the incomplete gear 802 and the push rod 704 to rotate. When the push rod 704 rotates, it is rotated from the notch 205 into the storage box 20 and acts on the bottom of the rightmost cardboard, thereby pushing the rightmost cardboard upward, so that the upper end of the rightmost cardboard is misaligned with the other cardboards. When the incomplete gear 802 rotates, it drives the L-shaped baffle 501 and the first rack rod 403 to move through the meshing action with the second rack rod 801. When the first rack rod 403 moves, it drives the threaded sleeve 401 through the meshing action with the gear 401. 2 rotates, and the screw 404 is driven to move by the threaded sleeve 402 and the threaded action of the screw 404. After the upper end of the rightmost cardboard is misaligned with the other cardboards, one end of the L-shaped baffle 501 is removed from the right side of the storage box 20. At the same time, the screw 404 acts on the rightmost cardboard to push the rightmost cardboard onto the conveyor belt 30, and then is transported to the cutting station by the conveyor belt 30, so that it is cut by the cutting mechanism at the cutting station; when the push rod 704 is rotated out of the storage box 20, the incomplete gear 802 is disengaged from the second rack rod 801, and the first elastic Component 503 pushes the L-shaped baffle 501 so that the L-shaped baffle 501 and the second rack rod 801 move in the opposite direction. One end of the L-shaped baffle 501 acts on the right side of the storage box 20 again to continue to block the subsequent cardboard. When the second rack rod 801 moves in the opposite direction, it drives the first rack rod 403 to move in the opposite direction synchronously. The reverse meshing action of the first rack rod 403 and the gear 401 drives the threaded sleeve 402 to rotate in the opposite direction. The reverse thread cooperation of the threaded sleeve 402 and the screw rod 404 drives the screw rod 404 to move in the opposite direction, thereby realizing the reset of the screw rod 404.
