[0047] The present utility model will be further described below by way of embodiments, but the present utility model is not limited to the scope of the described embodiments.

[0048] As Figures 1-5 shown, a corrugated cardboard cutting and feeding device includes a workbench plate 1; and further includes: a loading frame 2, the loading frame 2 is used for stacking and placing corrugated cardboard a; the loading frame 2 is fixedly installed on the top surface of the workbench plate 1, and a discharge slot 201 for the corrugated cardboard a to leave is opened at the bottom of one side of the loading frame 2; a side slot 202 is opened on the side of the loading frame 2 away from the discharge slot 201; a linear moving mechanism 5, the linear moving mechanism 5 is installed at the bottom of the workbench plate 1, and the output end of the linear moving mechanism 5 is fixedly connected with a pushing strip 11 for pushing the lowermost corrugated cardboard a in the loading frame 2 to leave from the discharge slot 201; a supporting flat plate 3, the supporting flat plate 3 is fixedly connected with the pushing strip 11, the supporting flat plate 3 penetrates through the side slot 202, and the supporting flat plate 3 is magnetically connected with a movable loading block 4 located outside the loading frame 2 and slidably arranged on the workbench plate 1; the movable loading block 4 is connected with a positioning and blocking part to block the movement of the movable loading block 4 to the side slot 202.

[0049] As Figure 2 shown, the linear moving mechanism 5 includes a first end frame 501, a screw rod 502, a second end frame 503, a nut 504, a motor 505 and a guide block 506; the first end frame 501 and the second end frame 503 are both fixedly connected to the bottom surface of the workbench plate 1, the screw rod 502 is rotatably installed between the first end frame 501 and the second end frame 503, the nut 504 is threadedly connected to the screw rod 502, and the top surface of the nut 504 is fixedly connected with the guide block 506, the guide block 506 is fixedly connected with the bottom of the pushing strip 11; the guide block 506 is slidably connected with a first guide groove 101 opened on the workbench plate 1, and a motor 505 is fixedly installed on the side surface of the first end frame 501 away from the screw rod 502, and the output shaft end of the motor 505 is fixedly connected with the end of the screw rod 502.

[0050] In the linear moving mechanism 5, the screw 502 is driven to rotate by the motor 505. Under the guiding action of the guide block 506 and the first guide groove 101, the nut 504 and the guide block 506 move along the length direction of the first guide groove 101, thereby driving the pushing bar 11 to move. By the pushing bar 11, the lowermost corrugated board a is pushed, so that the corrugated board a leaves from the discharge chute 201 for feeding.

[0051] As shown in Figures 2-3 At this time, it is the initial state for pushing the corrugated board a to move. The pushing bar 11 is located in the side groove 202 and not in the loading frame 2.

[0052] Among them, the motor 505 is preferably a servo motor 505. When the whole device is in use, the motor 505 needs to be externally connected to a power supply and a controller.

[0053] As shown in Figure 3 The top surface of the pushing bar 11 is flush with the top surface of the material supporting flat plate 3; the top surface of the material supporting flat plate 3 is flush with the top surface of the movable loading block 4.

[0054] During the process of pushing out the lowermost corrugated board a, at the beginning, the positions of the pushing bar 11, the material supporting flat plate 3, and the movable loading block 4 are in the state as shown in Figure 3 By driving the pushing bar 11 to approach the discharge chute 201, the pushing bar 11 pushes the corrugated board a, and the material supporting flat plate 3 moves with the pushing bar 11. The material supporting flat plate 3 drives the movable loading block 4 to move through magnetic attraction; when the movable loading block 4 moves to the side groove 202, a part of the movable loading block 4 is located inside the loading frame 2. Due to the action of the in-place block, it separates from the material supporting flat plate 3. After the corrugated board a is completely pushed out, the material supporting flat plate 3 is located at the discharge chute 201, and a part of the material supporting flat plate 3 is located inside the loading frame 2; the material supporting flat plate 3 and the movable loading block 4 are used to carry other corrugated boards a to be discharged, providing a position for the pushing bar 11 to reset without being blocked.

[0055] A terminal strip 6 is fixedly connected to one side of the material supporting flat plate 3 away from the pushing bar 11. At least one permanent magnet 7 is fixedly installed on the terminal strip 6, and the permanent magnet 7 is magnetically connected to the end of the movable loading block 4. The permanent magnet 7 is used to provide magnetic attraction.

[0056] As shown in Figures 3-4 The in-place blocking part includes a guide rod 8 and a guide sleeve 9; a second guide groove 102 is formed on the top surface of the workbench plate 1; the guide rod 8 is fixedly installed in the second guide groove 102, the inner wall of the guide sleeve 9 is in clearance fit with the rod surface of the guide rod 8, and the guide sleeve 9 is slidably installed in the second guide groove 102. The top surface of the guide sleeve 9 is fixedly connected to the bottom surface of the movable loading block 4.

[0057] When the movable loading block 4 moves, the guide sleeve 9 slides on the guide rod 8, as shown in Figures 3-4As shown, when the pusher bar 11 is located within the side groove 202, the guide sleeve 9 is in contact with the left side wall of the second guide groove 102. When the pusher bar 11 approaches the discharge groove 201 to push the corrugated cardboard a for discharging, the movable carrier block 4 is subjected to magnetic suction force and moves together with the material supporting flat plate 3 until the guide sleeve 9 is in contact with the right side wall of the second guide groove 102 and is blocked. At this time, the movable carrier block 4 cannot continue to move together with the material supporting flat plate 3, that is, it moves into place. At this time, the movable carrier block 4 moves to the side groove 202, and the right side of the movable carrier block 4 passes through the side groove 202 and enters the inside of the material loading frame 2.

[0058] During the reset process of the pusher bar 11, the material supporting flat plate 3 resets together with the pusher bar 11 and moves to the left. When the material supporting flat plate 3 approaches the movable carrier block 4 and contacts it, the material supporting flat plate 3 pushes the movable carrier block 4 to move until the guide sleeve 9 is in contact with the left side wall of the second guide groove 102, and it returns to the state as Figures 3-4 shown, and the pusher bar 11 returns to the side groove 202.

[0059] Furthermore, as Figures 4-5 shown, an inner groove 401 is formed inside the movable carrier block 4. A first guide hole 402 and a second guide hole 403 are respectively formed on one side of the movable carrier block 4 close to the end bar 6 and the top of the movable carrier block 4. One side and the top of the inner groove 401 are respectively communicated with the first guide hole 402 and the second guide hole 403. A positioning mechanism 10 is installed inside the movable carrier block 4. The positioning mechanism 10 includes a second inclined block 1003 that can move vertically. A positioning hole 203 for inserting the top end of the second inclined block 1003 is formed on the top surface of the side groove 202. The positioning mechanism 10 further includes an iron rod 1001, a first inclined block 1002, a second inclined block 1003, and a spring 1005. The first inclined block 1002 is arranged in the inner groove 401, and an iron rod 1001 is fixedly connected to one side of the first inclined block 1002. The iron rod 1001 is connected to the first guide hole 402 with a clearance fit, and the iron rod 1001 is aligned with the permanent magnet 7. The second inclined block 1003 is connected to the second guide hole 403 with a clearance fit, and the bottom surface of the second inclined block 1003 is in contact with the top surface of the first inclined block 1002. One side of the first inclined block 1002 away from the iron rod 1001 is elastically connected to the inner groove 401 wall through a spring 1005. The top surface of the first inclined block 1002 and the bottom surface of the second inclined block 1003 are both provided with mutually adapted inclined surfaces. A stopper 1004 is fixedly connected to one side of the second inclined block 1003, and the stopper 1004 is located in the inner groove 401.

[0060] Among them, in order to improve the stability of the movable carrier block 4 when moving to the side groove 202 and prevent the movable carrier block 4 from detaching, a positioning mechanism 10 that can automatically position and automatically release the positioning is added.

[0061] Among them, as Figures 4-5As shown, at this time, the material supporting flat plate 3 and the movable carrier block 4 are in a fitting state. The permanent magnet 7 is close to the iron rod 1001 and magnetically attracts the iron rod 1001. The iron rod 1001 abuts against the permanent magnet 7. Among them, the spring 1005 is in a stretched state, and the second inclined block 1003 is stuck in the second guide hole 403.

[0062] When the movable carrier block 4 moves to the side groove 202 and is blocked, the second inclined block 1003 is aligned with the positioning hole 203. At this time, the material supporting flat plate 3 continues to move to the right, separating the permanent magnet 7 from the iron rod 1001. The iron rod 1001 loses the magnetic attraction force. Through the elastic force of the spring 1005, the first inclined block 1002 and the iron rod 1001 are driven to move together. By the inclined surface of the first inclined block 1002 squeezing the second inclined block 1003, the second inclined block 1003 moves upward until the stop block 1004 abuts against the top wall of the inner groove 401. The second inclined block 1003 extends out of the second guide hole 403 and is inserted into the positioning hole 203 for automatic positioning.

[0063] Subsequently, the material supporting flat plate 3 moves in a reset manner and approaches the movable carrier block 4. Through the magnetic attraction of the permanent magnet 7, the iron rod 1001 and the first inclined block 1002 move together. The iron rod 1001 abuts against the permanent magnet 7, and at the same time, the spring 1005 is stretched. During the reset movement of the first inclined block 1002, the second inclined block 1003 falls back into the second guide hole 403 due to gravity and separates from the positioning hole 203, automatically releasing the positioning.

[0064] The utility model is not limited to the above embodiments. No matter what changes are made in its shape or structure, they all fall within the protection scope of the utility model. The protection scope of the utility model is defined by the appended claims. Those skilled in the art can make various changes or modifications to these embodiments without departing from the principle and essence of the utility model, but these changes and modifications all fall within the protection scope of the utility model.
