[0002] Corrugated board is also known as corrugated paperboard. Corrugated board is composed of at least one layer of corrugated paper and one layer of liner board (also called case board paper) bonded together, and has good elasticity and extensibility. Corrugated board is mainly used for manufacturing cartons, the sandwich of cartons, and other packaging materials for fragile goods. It is mainly made by using native straw pulp and waste paper through beating to make a base board similar to yellow board paper, then mechanically processed into a corrugated shape, and then bonded with case board paper on its surface with adhesives such as sodium silicate.

[0003] When producing corrugated board, first heat the corrugated paper, prepare a corrugated shape through a corrugating roll, then bond the prepared corrugated paper and the inner paper together with glue, and then bond the upper and lower layers of kraft paper together with glue. Heat and dry the formed corrugated board through an arc-shaped hot plate, and then cut it. Finally, stack the products.

[0004] When bundling and stacking the products, it is necessary to take out a few layers of corrugated paper, and then stack them together after bundling.

The blocking and aligning assembly 41 is used to block the movement of the corrugated paper and cooperate with the transfer conveyor belt 403 to drive the corrugated paper horizontally, so that the corrugated paper is sorted and aligned.

[0068] Among them, referring to Figure 3 , the blocking and aligning assembly 41 includes two blocking brackets 411 symmetrically arranged on both sides of the transfer conveyor belt 403. The bottom of the blocking bracket 411 is connected to the transfer and conveying table 401. A blocking chute 412 is vertically provided on the side of the blocking bracket 411 facing the transfer conveyor belt 403. A blocking slider 413 is movably arranged up and down in the blocking chute 412. A linear motor is provided on the blocking bracket 411, and the linear motor is connected to the blocking slider 413 and drives the blocking slider 413 to move vertically.

When the blocking slider 413 moves to the top of the blocking chute 412, the blocking plate 414 is located above the moving track of the corrugated paper and does not affect the movement of the corrugated paper. When the blocking slider 413 moves to the bottom of the blocking chute 412, the blocking plate 414 is located on the moving track of the corrugated paper to block the movement of the corrugated paper.

[0069] Further, referring to Figure 5, the separation and pushing mechanism 5 of this embodiment includes a separation component 51 and a lifting component 53. The separation component 51 is used to separate the corrugated paper in the uppermost area from the corrugated paper in the lower area. The separation component 51 includes a separation groove 511 provided at the top of the right side surface of the first receiving plate 311. A separation conveyor belt 512 is provided in the separation groove 511, and the separation conveyor belt 512 is flush with the surface of the first receiving plate 311. The lifting component 53 is used to push the remaining corrugated paper upward, so that the corrugated paper in the topmost area moves to the action area of the separation component 51, facilitating the re-separation of the corrugated paper. The lifting component 53 includes two lifting chutes 531 provided on the right side surface of the first receiving plate 311. The two lifting chutes 531 are parallel to each other.

[0070] When using the product automatic loading equipment of this embodiment, first, stack the corrugated paper on the second receiving plate 312 in a horizontal state. Second, the output end of the flipping hydraulic cylinder 323 contracts, driving the first receiving plate 311 and the second receiving plate 312 to flip leftward until the first receiving plate 311 fits against the left inclined platform of the rectangular installation frame 322. Third, the output end of the lifting cylinder 534 extends, pushing the corrugated paper upward, so that the corrugated paper in the topmost area moves to the area where the separation component 51 is located. Then, the separation conveyor belt 512 operates, driving the corrugated paper in the area of the separation component 51 to separate from the corrugated paper below, and driving the separated upper part of the corrugated paper to move onto the transfer conveyor belt 403. After that, the transfer conveyor belt 403 cooperates with the separation component 51 to receive the separated corrugated paper and convey it to the bundling machine 1. Finally, the bundling machine 1 bundles the stacked corrugated paper and then transfers it to the subsequent work section.

[0071] It should be noted that when the transfer conveyor belt 403 conveys the corrugated paper, first, the blocking and aligning component 41 operates.

Second, the transfer conveyor belt 403 stops conveying, and at the same time, the blocking and aligning component 41 resets, and the blocking plate 414 moves above the corrugated paper. Finally, the transfer conveyor belt 403 starts again to convey the corrugated paper until the corrugated paper is received by the bundling machine 1.

[0073] S1. The corrugated paper is stacked and placed on the second receiving plate 312 in a horizontal state;

[0074] S2. The output end of the flipping hydraulic cylinder 323 contracts, driving the first receiving plate 311 and the second receiving plate 312 to flip to the left until the first receiving plate 311 fits against the left inclined platform of the rectangular mounting frame 322;

[0075] S3. The output end of the lifting cylinder 534 extends, pushing the corrugated paper upward so that the corrugated paper in the uppermost area moves to the area where the separation assembly 51 is located;

[0076] S4. The separation conveyor belt 512 operates, driving the corrugated paper in the area of the separation assembly 51 to separate from the corrugated paper below, and driving the separated upper corrugated paper to move onto the transfer conveyor belt 403;

[0078] S6. The bundling machine 1 bundles the stacked corrugated paper and then transfers it to the subsequent work section.

[0079] It should be noted that in step S5, the specific process of the transfer conveyor belt 403 conveying the corrugated paper is as follows:

[0080] First, the blocking and aligning assembly 41 operates. The linear motor on the blocking bracket 411 drives the blocking slide 413 to move downward, and then drives the blocking plate 414 to move downward to the corrugated paper movement trajectory. The corrugated paper is blocked and intercepted after moving to the blocking plate 414, so as to be sorted and aligned;

[0081] Secondly, the transfer conveyor belt 403 stops conveying, and at the same time the blocking and aligning assembly 41 resets, and the blocking plate 414 moves above the corrugated paper;

[0082] Finally, the transfer conveyor belt 403 starts again to convey the corrugated paper until the corrugated paper is received by the bundling machine 1.

The penetrating direction of the pushing chute 522 is perpendicular to the conveying direction of the separation conveyor belt 512. A pushing slider 523 is movably arranged in the pushing chute 522. The moving direction of the pushing slider 523 is the same as the conveying direction of the separation conveyor belt 512.

[0085] It should be noted that a linear motor is arranged on the pushing plate 521. The linear motor is connected to the pushing slider 523 and drives the pushing slider 523 to move along the pushing chute 522. A horizontal insertion cylinder 524 is arranged on the outer side of the pushing slider 523. When the output end of the horizontal insertion cylinder 524 is in the fully extended state, the output end of the horizontal insertion cylinder 524 passes through the pushing slider 523 and extends to the area where the corrugated paper is located.

[0086] Due to the arrangement of the pushing component 52, when the product automatic feeding device is used, after the separation component 51 drives the corrugated paper in the area of the separation component 51 to be separated from the corrugated paper below, the output end of the horizontal insertion cylinder 524 extends out and is inserted into the separation gap between the upper corrugated paper and the lower corrugated paper. Then, the linear motor on the pushing plate 521 acts to drive the pushing slider 523 to move obliquely upward along the pushing chute 522, thereby driving the upper corrugated paper to move onto the transfer conveyor belt 403. Then, the transfer conveyor belt 403 cooperates with the movement of the pushing component to receive the separated corrugated paper. Finally, the bundling machine 1 bundles the stacked corrugated paper in multiple layers and then transfers it to the subsequent working section.
