Description

Technical Field

[0001] This invention relates to the field of paperboard production technology, and in particular to a paper conveying device and a paper conveying method. Background Technology

[0002] Corrugated paper is a type of packaging material mainly used in the manufacture of cartons, carton fillings, and for fragile goods, with a wide range of applications. The conventional structure of corrugated paper typically consists of a face liner, a back liner, and a corrugated core liner. The corrugated core liner usually extends along the wavy path in the length direction, making it difficult for the corrugated paper to bend along its length, but easier to bend along its width. Therefore, in the production process, the width direction of the corrugated paper is usually aligned with the conveying direction to reduce bending due to gravity. However, in actual production, the size of the factory floor space often limits the size of corrugated paper production lines. Placing the corrugated paper straight in the factory along the same direction requires a bending and turning design for the corrugated paper production line. However, after transferring the corrugated paper from the original conveyor belt to the next conveyor belt with a conveying direction perpendicular to the original conveyor belt, the length direction of the corrugated paper will be set in the same direction as the conveying direction. At this time, the corrugated paper is easy to bend under the action of gravity, causing the corrugated paper to get stuck between the two conveyor belts, affecting the normal conveying process. In addition, the dimensions of corrugated paper of different specifications are often different. After the paper conveying direction is changed, it is difficult to control the paper of each specification to be conveyed to the next processing station in the middle of the conveyor line, making it difficult to complete the subsequent processing of the paper. Summary of the Invention

[0003] The present invention aims to at least solve one of the technical problems existing in the prior art. To this end, the present invention proposes a paper conveying device that can improve the problem that it is difficult for papers of various sizes to continue moving in the middle of the conveying line when the conveying direction changes.

[0004] This application also proposes a paper conveying method for use in paper conveying equipment.

[0005] According to a first aspect of the present invention, a paper conveying device includes: a first conveying component disposed on a paper movement path; the conveying direction of the first conveying component is a first direction; a second conveying component disposed on the paper movement path; the second conveying component includes a third conveying line, a fourth conveying line, a paper lifting component, and a pressing component, wherein the conveying directions of the third conveying line and the fourth conveying line are both in the second direction, the fourth conveying line is located at the tail side of the third conveying line, the third conveying line is located below the tail side of the first conveying component, and the first direction and the second direction are perpendicular to each other; the pressing component is disposed above the fourth conveying line, and... There is a gap between the paper and the fourth conveyor line for paper to pass through. Two paper lifting members are provided, both of which are located on the fourth conveyor line and are respectively located on both sides of the pressing member along the first direction. The top of the paper lifting member is provided with a paper lifting surface, which intersects with the conveying surface of the fourth conveyor line and forms an angle between them. The height of the paper lifting surface gradually increases along the second direction. A second adjusting component is connected to the fourth conveyor line and can drive the fourth conveyor line to move along the second direction. A fifth conveyor line is provided on the paper's movement path and is located below the tail side of the fourth conveyor line. The conveying direction of the fifth conveyor line is the first direction.

[0006] The paper conveying device according to the present invention has at least the following beneficial effects:

[0007] In an embodiment of the present invention, the corrugated core paper interlayer of the corrugated paper extends along the corrugated path in the length direction. The corrugated paper can be placed on a first conveying member, with the width direction of the corrugated paper being a first direction. The first conveying member can convey the corrugated paper along the first direction and output the corrugated paper from the tail side of the first conveying member, so that the corrugated paper falls from the first conveying member onto a third conveying line. The third conveying line can receive the corrugated paper output from the first conveying member. Since the corrugated paper is difficult to bend around its width, the first conveying member can output the corrugated paper to the third conveying line with high safety. The third conveying line outputs the corrugated paper from the tail side of the third conveying line to a fourth conveying line. There is a gap between the pressing member and the fourth conveying line. When the corrugated paper passes through the gap, the middle part of the corrugated paper can be pressed down by the pressing member. Since the paper lifting members are respectively arranged on both sides of the pressing member along the first direction, the paper lifting members can lift the two sides of the corrugated paper through the paper lifting surface, so that the two sides of the corrugated paper bend towards the middle part of the corrugated paper. The corrugated paper is folded, forming a crease extending along the second direction on the corrugated paper. After the fourth conveyor line outputs the corrugated paper from the output end, the folded corrugated paper reduces the degree to which the corrugated paper bends downwards due to gravity along its length. It also reduces the degree of bending of the portion of the corrugated paper outside the fourth conveyor line relative to the portion inside the fourth conveyor line. When the fourth conveyor line transports the corrugated paper to the fifth conveyor line located below the tail of the fourth conveyor line, it reduces the possibility of the corrugated paper getting stuck between the fourth and fifth conveyor lines, enabling the paper conveying equipment to smoothly turn and transport the corrugated paper. Furthermore, when the fourth conveyor line transports corrugated paper of different specifications to the fifth conveyor line, the second adjusting component can control the fourth conveyor line to move along the second direction to adjust the length of the fourth conveyor line extending directly above the fifth conveyor line, so that the corrugated paper of each specification falls to the middle position of the fifth conveyor line, thereby improving the problem that the paper of each specification is difficult to continue moving in the middle of the conveyor line when the conveying direction changes.

[0008] According to some embodiments of the present invention, the two paper lifting members are arranged symmetrically to each other, and the paper lifting surfaces of the two paper lifting members are inclined toward the direction of the pressing member.

[0010] According to some embodiments of the present invention, a second limiting component is further included. The second limiting component includes a second limiting plate and a second adjusting structure. The second limiting plate is disposed on the side of the fifth conveyor line away from the fourth conveyor line and is used to limit the paper output from the fourth conveyor line to control the position of the paper falling on the fifth conveyor line. The second adjusting structure is drivenly connected to the second limiting plate and is capable of driving the second limiting plate to move in a second direction.

[0011] According to some embodiments of the present invention, a first adjusting component is further included; the first conveying component includes a first conveying line and a second conveying line, the second conveying line being located at the tail side of the first conveying line, and the third conveying line being located below the second conveying line; the first adjusting component is connected to the second conveying line and is capable of driving the second conveying line to move along a first direction.

[0012] According to some embodiments of the present invention, a first limiting component is further included. The first limiting component includes a first limiting plate and a first adjusting structure. The first limiting plate is disposed on the side of the third conveyor line away from the second conveyor line and is used to limit the paper output from the second conveyor line to control the position of the paper falling on the third conveyor line. The first adjusting structure is drivenly connected to the first limiting plate and can drive the first limiting plate to move along a first direction.

[0013] According to some embodiments of the present invention, a blocking component is further included, the blocking component comprising a first blocking plate, a second blocking plate, a third blocking plate, and a fourth blocking plate. The first blocking plate and the second blocking plate are both disposed above the first conveyor line, and the third blocking plate is disposed on the first side of the first conveyor line. A paper stack storage area is defined between the first blocking plate, the second blocking plate, the third blocking plate, and the first conveyor line. The first blocking plate is located on the front side of the paper stack storage area, the second blocking plate is located on the left or right side of the paper stack storage area, and the third blocking plate is located on the rear side of the paper stack storage area. The fourth blocking plate is disposed below the first blocking plate and forms a channel between itself and the first conveyor belt for allowing multiple sheets of paper to pass through. The height of the channel gradually decreases along a first direction.

[0014] According to some embodiments of the present invention, the blocking component further includes a position adjustment assembly, which is drivenly connected to the first blocking plate and the second blocking plate and is capable of driving the first blocking plate and the second blocking plate to move along a first direction and a second direction.

[0015] According to some embodiments of the present invention, a feeding component is further included, which is disposed on one side of the first conveyor line and is used to feed the paper stack to the paper stack storage area.

[0016] The paper conveying method according to a second aspect of this application is applied to the paper conveying device of the first aspect embodiment. The paper conveying method includes the following steps:

[0017] The corrugated paper is placed on the first conveying component, and the width direction of the corrugated paper is aligned with the first direction.

[0018] The corrugated paper is conveyed along a first direction by the first conveying component, and the corrugated paper is output from the first conveying component to a third conveying line located below the tail side of the first conveying component;

[0019] The corrugated paper is conveyed along the second direction via the third conveyor line and output to the fourth conveyor line located at the tail side of the first conveyor component.

[0020] The corrugated paper on the fourth conveyor line is pressed down by the pressing component, and the left and right sides of the corrugated paper on the fourth conveyor line are lifted by the two lifting components, so that the left and right sides of the corrugated paper are bent towards the middle.

[0021] The fourth conveyor line is controlled to move along the second direction by the second adjustment component;

[0022] The corrugated paper is conveyed along the second direction via the fourth conveyor line and output from the fourth conveyor line to the fifth conveyor line located at the tail of the fourth conveyor line.

[0023] Corrugated paper is conveyed along the first direction via the fifth conveyor line.

[0024] The paper feeding method according to the embodiments of this application can achieve at least the following beneficial effects:

[0025] In an embodiment of the present invention, the corrugated core paper interlayer of the corrugated paper extends along the corrugated path in the length direction. The corrugated paper can be placed on a first conveying member, with the width direction of the corrugated paper being a first direction. The first conveying member can convey the corrugated paper along the first direction and output the corrugated paper from the tail side of the first conveying member, so that the corrugated paper falls from the first conveying member onto a third conveying line. The third conveying line can receive the corrugated paper output from the first conveying member. Since the corrugated paper is difficult to bend around its width, the first conveying member can output the corrugated paper to the third conveying line with high safety. The third conveying line outputs the corrugated paper from the tail side of the third conveying line to a fourth conveying line. There is a gap between the pressing member and the fourth conveying line. When the corrugated paper passes through the gap, the middle part of the corrugated paper can be pressed down by the pressing member. Since the paper lifting members are respectively arranged on both sides of the pressing member along the first direction, the paper lifting members can lift the two sides of the corrugated paper through the paper lifting surface, so that the two sides of the corrugated paper bend towards the middle part of the corrugated paper. The corrugated paper is folded, forming a crease extending along the second direction on the corrugated paper. After the fourth conveyor line outputs the corrugated paper from the output end, the folded corrugated paper reduces the degree to which the corrugated paper bends downwards due to gravity along its length. It also reduces the degree of bending of the portion of the corrugated paper outside the fourth conveyor line relative to the portion inside the fourth conveyor line. When the fourth conveyor line transports the corrugated paper to the fifth conveyor line located below the tail of the fourth conveyor line, it reduces the possibility of the corrugated paper getting stuck between the fourth and fifth conveyor lines, enabling the paper conveying equipment to smoothly turn and transport the corrugated paper. Furthermore, when the fourth conveyor line transports corrugated paper of different specifications to the fifth conveyor line, the second adjusting component can control the fourth conveyor line to move along the second direction to adjust the length of the fourth conveyor line extending directly above the fifth conveyor line, so that the corrugated paper of each specification falls to the middle position of the fifth conveyor line, thereby improving the problem that the paper of each specification is difficult to continue moving in the middle of the conveyor line when the conveying direction changes.

[0041] The following is for reference. Figures 1 to 7 A paper conveying device and a paper conveying method according to embodiments of the present invention are described.

[0042] According to a first aspect embodiment of the paper conveying device, the paper conveying device includes a first conveying component 100, a second conveying component 200, a second adjusting component, and a fifth conveying line 300; the first conveying component 100 is disposed on the paper's movement path; the conveying direction of the first conveying component 100 is a first direction; the second conveying component 200 is disposed on the paper's movement path; the second conveying component 200 includes a third conveying line 210, a fourth conveying line 220, a paper lifting component 230, and a pressing component 240, the conveying directions of the third conveying line 210 and the fourth conveying line 220 are both the second direction, the fourth conveying line 220 is located at the tail side of the third conveying line 210, and the third conveying line 210 is located below the tail side of the first conveying component 100, the first direction being the same as the first conveying line 200. The two directions are perpendicular to each other; the pressing member 240 is disposed above the fourth conveyor line 220 and has a gap between it and the fourth conveyor line 220 for paper to pass through; two paper lifting members 230 are disposed, both on the fourth conveyor line 220, and respectively disposed on both sides of the pressing member 240 along the first direction; the top of the paper lifting member 230 is provided with a paper lifting surface, which intersects with the conveying surface of the fourth conveyor line 220 and has an included angle between them; the height of the paper lifting surface gradually increases along the second direction; the second adjusting component is connected to the fourth conveyor line 220 and can drive the fourth conveyor line 220 to move along the second direction; the fifth conveyor line 300 is disposed on the paper moving path and located below the tail side of the fourth conveyor line 220; the conveying direction of the fifth conveyor line 300 is the first direction.

[0043] In an embodiment of the present invention, the corrugated core paper layer of the corrugated paper extends along a wavy path in the length direction. The corrugated paper can be placed on the first conveying member 100, with the width direction of the corrugated paper being a first direction. The first conveying member 100 can convey the corrugated paper along the first direction and output the corrugated paper from the tail side of the first conveying member 100, so that the corrugated paper falls from the first conveying member 100 onto the third conveying line 210. The third conveying line 210 can receive the corrugated paper output from the first conveying member 100. Since the corrugated paper is difficult to bend around its width direction... This design ensures high safety when the first conveying component 100 outputs corrugated paper to the third conveying line 210. The third conveying line 210 outputs the corrugated paper from its tail side to the fourth conveying line 220. A gap exists between the pressing component 240 and the fourth conveying line 220. When the corrugated paper passes through the gap, the pressing component 240 can press down the middle portion of the corrugated paper. Since the lifting component 230 is positioned on both sides of the pressing component 240 along the first direction, it can lift both sides of the corrugated paper, ensuring that both sides face the corrugated paper. The middle part of the corrugated paper is bent, forming a crease extending along the second direction on the corrugated paper. After the fourth conveyor line 220 outputs the corrugated paper from the output end, the bent corrugated paper can reduce the degree of downward bending of the corrugated paper due to gravity around the length direction of the corrugated paper, and can also reduce the degree of bending of the part of the corrugated paper outside the fourth conveyor line 220 relative to the part of the corrugated paper inside the fourth conveyor line 220. When the fourth conveyor line 220 conveys the corrugated paper to the fifth conveyor line 300 located below the tail side of the fourth conveyor line 220, it can reduce the corrugated paper getting stuck on the fourth conveyor line 220 and the fifth conveyor line 300. The possibility of five conveyor lines 300 is provided to enable the paper conveying equipment to smoothly turn and convey corrugated paper; and when the fourth conveyor line 220 conveys corrugated paper of different specifications to the fifth conveyor line 300, the second adjustment component can control the fourth conveyor line 220 to move along the second direction to adjust the length of the fourth conveyor line 220 extending directly above the fifth conveyor line 300, so that the corrugated paper of each specification falls to the middle position of the fifth conveyor line 300, thereby improving the problem that the paper of each specification is difficult to continue moving in the middle of the conveyor line when the conveying direction changes.

[0044] Reference Figure 1 and Figure 5 In some embodiments of the present invention, the two paper lifting components 230 are arranged symmetrically to each other, and the paper lifting surfaces of the two paper lifting components 230 are inclined toward the downward pressing component 240.

[0045] Specifically, there are two paper lifting components 230, which are respectively arranged on both sides of the pressing component 240 along the first direction. The two paper lifting surfaces are inclined and symmetrically arranged towards the pressing component 240, and the height of the paper lifting surfaces gradually increases along the second direction, so that the paper lifting surfaces are inclined towards the middle part of the pressing component 240. This allows the two sides of the corrugated paper to bend towards the middle part of the corrugated paper, and the size and degree of bending of the bent parts on both sides of the corrugated paper are approximately equal, reducing the degree of tilting of the corrugated paper to both sides, thereby further improving the stability of the conveying.

[0046] Reference Figure 1 and Figure 5 In some embodiments of the present invention, the pressing member 240 includes a first elastic member and a pressing roller 241. The first elastic member is connected to the pressing roller 241 and has an elastic restoring force that pushes the pressing roller 241 toward a direction close to the fourth conveyor line 220. The pressing roller 241 is used to abut against the paper on the fourth conveyor line 220.

[0047] The pressure roller 241 can press down the portion of the corrugated paper located on the fourth conveyor line 220 to compress the corrugated paper and prevent it from slipping. It can also work with the paper lifting component 230 to bend the corrugated paper. When the corrugated paper moves on the fourth conveyor line 220, the pressure roller 241 can rotate relative to the fourth conveyor line 220 to reduce the friction between the corrugated paper and the pressure roller 241, thereby reducing the difficulty of the corrugated paper moving on the fourth conveyor line 220. Specifically, an annular structure for contacting the corrugated paper is fitted on the pressure roller 241. The annular structure is elastic to reduce the damage caused by the collision between the corrugated paper and the pressure roller 241, and it can also compress corrugated paper of different thicknesses, improving the adaptability of the pressure roller 241.

[0048] Specifically, the pressing member 240 also includes a mounting plate, a rotating rod, and a rotating shaft. The rotating shaft passes through the middle part of the rotating rod and the mounting plate. The rotating rod can rotate relative to the mounting plate through the rotating shaft. The pressing wheel 241 is rotatably disposed at one end of the rotating rod. The two ends of the first elastic member are respectively connected to the end of the rotating rod away from the pressing wheel 241 and the mounting plate. The first elastic member has an elastic restoring force that pushes the end of the rotating rod with the pressing wheel 241 to rotate in a direction closer to the fourth conveyor line 220.

[0049] Both the middle part of the rotating rod and the mounting plate are provided with connecting holes. The rotating shaft passes through the connecting holes on the mounting plate and the rotating rod, so that the rotating rod can rotate along the axis of the rotating shaft. One end of the rotating rod is rotatably connected to the lower pressure wheel 241, and the lower pressure wheel 241 is located below the mounting plate. Since different corrugated papers have different thicknesses, and when conveying corrugated papers arranged in a fish-scale pattern, the corrugated paper is stacked on top of each other. By rotating the rotating rod relative to the mounting plate, the position of the lower pressure wheel 241 can be adjusted. The first elastic element can push the end of the rotating rod with the lower pressure wheel 241 to rotate towards the direction close to the fourth conveyor line 220 until the lower pressure wheel 241 abuts against the corrugated paper on the fourth conveyor line 220, so that the lower pressure wheel 241 can stably press down corrugated papers of different thicknesses and corrugated papers arranged in a fish-scale pattern. The elastic structure can be a tension spring.

[0050] Specifically, multiple pressure rollers 241 are provided, and multiple rotating rods, first elastic elements and rotating shafts are provided correspondingly. Multiple pressure rollers 241 extend along the direction from the input end to the output end of the paper lifting assembly to improve the stability of pressing the corrugated paper. There may be two or more pressure members 240 to further improve the stability of pressing the corrugated paper.

[0051] Reference Figure 1 , Figure 5 and Figure 6 In some embodiments of the present invention, a second limiting component 500 is further included. The second limiting component 500 includes a second limiting plate 520 and a second adjusting structure 510. The second limiting plate 520 is disposed on the side of the fifth conveyor line 300 away from the fourth conveyor line 220 and is used to limit the paper output from the fourth conveyor line 220 to control the position of the paper falling on the fifth conveyor line 300. The second adjusting structure 510 is drivenly connected to the second limiting plate 520 and can drive the second limiting plate 520 to move in a second direction.

[0052] The second limiting plate 520 is disposed on the side of the fifth conveyor line 300 away from the fourth conveyor line 220. The second limiting plate 520 is used to limit the corrugated paper output from the fourth conveyor line 220 so that the corrugated paper falls into the middle of the fifth conveyor line 300. The second limiting component 500 is disposed on the left edge of the fifth conveyor line 300. The fourth conveyor line 220 can convey the corrugated paper along the second direction. Under the action of the second limiting component 500, the corrugated paper conveyed by the fourth conveyor line 220 can be limited by the second limiting component 500 so that it falls into the middle of the fifth conveyor line 300.

[0053] Furthermore, the second limiting component 500 includes a second adjusting structure 510 and a second limiting plate 520. The second limiting plate 520 is located above the fifth conveyor line 300 and extends along the first direction. The second adjusting structure 510 is connected to the second limiting plate 520, and the second adjusting structure 510 can drive the second limiting plate 520 to move along the second direction. A limiting area is formed between the tail side of the fourth conveyor line 220 and the second limiting plate 520. When the fourth conveyor line 220 conveys corrugated paper, the second adjusting structure 510 can drive the second limiting plate 520 to move along the second direction, and the second adjusting component can drive the fourth conveyor line 220 to move along the second direction to control the distance between the second limiting plate 520 and the fourth conveyor line 220. This allows the limiting area to be located directly above the middle of the fifth conveyor line 300, thereby improving the accuracy of the corrugated paper output from the fourth conveyor line 220 falling into the middle of the fifth conveyor line 300.

[0054] Specifically, the second limiting component 500 further includes a second mounting bracket 511, which includes a second guide rod 512. A second adjusting structure 510 is disposed on the second mounting bracket 511, and the second adjusting structure 510 includes a second driver 513 and a second lead screw 514. The output end of the second driver 513 is connected to the second lead screw 514. Both the second lead screw 514 and the second guide rod 512 extend along a first direction. Both the second lead screw 514 and the second guide rod 512 pass through the second limiting plate 520, and the second lead screw 514 is threaded to the second limiting plate 520. The second guide rod 512 is slidably connected to the second limiting plate 520. The second driver 513 may include a second motor and a second transmission chain. The second motor is mounted on the second mounting bracket 511, and the second transmission chain is connected to both the second motor and the second lead screw 514. Both the second guide rod 512 and the second lead screw 514 extend along a second direction and pass through the second limiting plate 520. The second guide rod 512 is slidably connected to the second limiting plate 520, and the second lead screw 514 is threadedly connected to the second limiting plate 520. The second motor can drive the second lead screw 514 to rotate through the chain transmission structure, thereby enabling the second lead screw 514 to drive the second limiting plate 520 to move along the axial direction of the second guide rod 512.

[0055] In some embodiments of the present invention, the second adjustment component includes a second adjustment motor, a second gear, and a second rack. The second rack extends along a second direction, and the second gear and the second rack mesh with each other. The second gear is connected to the output end of the second adjustment motor, and the second rack is connected to the fourth conveyor line 220. The second gear and the second rack mesh with each other, and under the drive of the second adjustment motor, the second gear can rotate, thereby driving the second rack to move along the second direction, so as to realize the movement of the fourth conveyor line 220 along the second direction.

[0056] In some embodiments of the present invention, a first adjustment component is further included; the first conveying component 100 includes a first conveying line 110 and a second conveying line 120, the second conveying line 120 being located at the tail side of the first conveying line 110, and a third conveying line 210 being located below the second conveying line 120; the first adjustment component is connected to the second conveying line 120 and is capable of driving the second conveying line 120 to move along a first direction.

[0057] The first conveyor line 110 and the second conveyor line 120 can convey corrugated paper along a first direction, and the third conveyor line 210 can convey corrugated paper along a second direction. The second conveyor line 120 is located at the tail side of the first conveyor line 110 in the first direction, and the tail end of the second conveyor line 120 can extend directly above the third conveyor line 210. The first adjustment component can be installed on the first conveyor line 110 and is connected to the second conveyor line 120.

[0058] When the paper conveying equipment is in operation, the first conveyor line 110 transports the corrugated paper along the first direction to the second conveyor line 120, the second conveyor line 120 transports the corrugated paper along the first direction to the third conveyor line 210, and the third conveyor line 210 transports the corrugated paper along the second direction.

[0059] When the second conveyor line 120 conveys corrugated paper onto the third conveyor line 210, for larger corrugated paper, the first adjusting component can drive the second conveyor line 120 to move closer to the first conveyor line 110 along the first direction, away from the center of the third conveyor line 210, so that the larger corrugated paper can fall into the center of the third conveyor line 210; for smaller corrugated paper, the first adjusting component can drive the second conveyor line 120 to move away from the first conveyor line 110 along the first direction, closer to the center of the third conveyor line 210, so that the smaller corrugated paper can fall into the center of the third conveyor line 210.

[0060] Furthermore, the first adjustment component can adjust the length of the second conveyor line 120 extending to the middle of the third conveyor line 210 according to the specifications of the corrugated paper, so that the corrugated paper conveyed by the second conveyor line 120 can fall into the middle of the third conveyor line 210.

[0061] In some embodiments of the present invention, the first adjustment component includes a first adjustment motor, a first gear, and a first rack. The first rack extends along a first direction, and the first gear and the first rack mesh with each other. The first gear is connected to the output end of the first adjustment motor, and the first rack is connected to the second conveyor line 120. The first gear and the first rack mesh with each other, and under the drive of the first adjustment motor, the first gear can rotate, thereby driving the first rack to move along the first direction, so as to realize that the second conveyor line 120 moves along the first direction.

[0062] Furthermore, the paper conveying equipment also includes a first guide assembly, and the second conveyor line 120 includes a second side plate. A first rack is disposed on the second side plate, and the second side plate is connected to the first guide assembly. The first guide assembly guides the second side plate to move along a first direction. The first guide assembly can be installed on the first conveyor line 110, and the first rack can be installed on the second side plate. The second side plate is slidably connected to the first guide assembly, so that under the drive of the first adjusting motor, the first rack can drive the second side plate to move along the first direction. By setting the first guide assembly, the first guide assembly can provide support and guidance for the first rack.

[0063] Specifically, the first conveyor line 110 includes a first side plate, and the first guide assembly includes two sets of first roller groups. Each first roller group includes multiple first rollers arranged along a first direction. The first rollers are rotatably mounted on the first side plate. The second side plate is located between the two sets of first roller groups and abuts against a portion of the first rollers. For example, as shown in Figures 1 and 2, the first side plate has two sets of first roller groups distributed along the vertical direction. Each set of first roller groups includes multiple first rollers arranged at intervals along the first direction. The second side plate is located between the two sets of first roller groups, and the upper end face of the second side plate abuts against the first rollers of the upper first roller group, while the lower end face of the second side plate abuts against the first rollers of the lower first roller group. Driven by the first adjusting motor, the second side plate can move left and right relative to the first rollers. By setting two sets of first roller groups, the first rollers and the second side plate experience rolling friction, reducing the ease of movement of the second side plate.

[0064] Furthermore, two sets of the first guide assembly can be arranged side by side in the front-back direction. In this case, two first gears, two first racks, and two second side plates are arranged side by side in the front-back direction. The two first gears can be located at both ends of the first drive shaft, and the first drive shaft is connected to the output end of the first regulating motor.

[0065] The first conveyor line 110, the second conveyor line 120, the third conveyor line 210, the fourth conveyor line 220 and the fifth conveyor line 300 are all conveyor belt conveying structures; among them, the fourth conveyor line 220 is composed of two conveyor belt conveying structures spliced ​​together, and the paper lifting component 230 and the pressing component 240 are both set on one of the conveyor belt conveying structures.

[0066] Reference Figures 1 to 3In some embodiments of the present invention, a first limiting component 400 is further included. The first limiting component 400 includes a first limiting plate 420 and a first adjusting structure 410. The first limiting plate 420 is disposed on the side of the second conveyor line 120 away from the first conveyor line 110 and is used to limit the paper output from the second conveyor line 120 to control the position of the paper falling on the third conveyor line 210. The first adjusting structure 410 is drivenly connected to the first limiting plate 420 and can drive the first limiting plate 420 to move along a first direction.

[0067] The first limiting plate 420 is disposed on the side of the third conveyor line 210 away from the second conveyor line 120. The first limiting plate 420 is used to limit the corrugated paper output from the second conveyor line 120 so that the corrugated paper falls into the middle of the third conveyor line 210. The first limiting component 400 is disposed on the left edge of the third conveyor line 210. The second conveyor line 120 can convey the corrugated paper along the first direction. Under the action of the first limiting component 400, the corrugated paper conveyed by the second conveyor line 120 can be limited by the first limiting component 400 so that it falls into the middle of the third conveyor line 210.

[0068] Furthermore, the first limiting component 400 includes a first adjusting structure 410 and a first limiting plate 420. The first limiting plate 420 is located above the third conveyor line 210 and extends along the second direction. The first adjusting structure 410 is connected to the first limiting plate 420, and the first adjusting structure 410 can drive the first limiting plate 420 to move along the first direction. A limiting area is formed between the tail side of the second conveyor line 120 and the first limiting plate 420. When the second conveyor line 120 conveys corrugated paper, the first adjusting structure 410 can drive the first limiting plate 420 to move along the first direction, and the first adjusting component can drive the second conveyor line 120 to move along the first direction to control the distance between the first limiting plate 420 and the second conveyor line 120. This allows the limiting area to be located directly above the middle of the third conveyor line 210, thereby improving the accuracy of the corrugated paper output from the second conveyor line 120 falling into the middle of the third conveyor line 210.

[0069] Specifically, the first limiting component 400 further includes a first mounting bracket 411, which includes a first guide rod 412. A first adjusting structure 410 is disposed on the first mounting bracket 411, and the first adjusting structure 410 includes a first driver 413 and a first lead screw 414. The output end of the first driver 413 is connected to the first lead screw 414. Both the first lead screw 414 and the first guide rod 412 extend along a first direction and pass through the first limiting plate 420. The first lead screw 414 is threaded to the first limiting plate 420. The connection is as follows: the first guide rod 412 is slidably connected to the first limiting plate 420; the first driver 413 may include a first motor and a first transmission chain. The first motor is mounted on the first mounting bracket 411, and the first transmission chain is connected to both the first motor and the first lead screw 414. Both the first guide rod 412 and the first lead screw 414 extend along a second direction and pass through the first limiting plate 420. The first guide rod 412 is slidably connected to the first limiting plate 420, and the first lead screw 414 is threadedly connected to the first limiting plate 420. The first motor can drive the first lead screw 414 to rotate through the chain transmission structure, thereby enabling the first lead screw 414 to drive the first limiting plate 420 to move along the axial direction of the first guide rod 412.

[0070] Reference Figure 1 , Figure 2 and Figure 4 In some embodiments of the present invention, a blocking component 600 is further included. The blocking component 600 includes a first blocking plate 610, a second blocking plate 620, a third blocking plate 630, and a fourth blocking plate 640. The first blocking plate 610 and the second blocking plate 620 are both disposed above the first conveyor line 110, and the third blocking plate 630 is disposed on the first side of the first conveyor line 110. A paper stack storage area 601 is defined between the first blocking plate 610, the second blocking plate 620, the third blocking plate 630, and the first conveyor line 110. The first blocking plate 610 is located on the front side of the paper stack storage area 601, the second blocking plate 620 is located on the left or right side of the paper stack storage area 601, and the third blocking plate 630 is located on the rear side of the paper stack storage area 601 to define the position of the paper stack on the first conveyor line 110. The fourth blocking plate 640 is disposed on the lower side of the first blocking plate 610 and forms a channel between it and the first conveyor belt for allowing multiple sheets of paper to pass through. The height of the channel gradually decreases along a first direction.

[0071] Specifically, the first conveyor line 110 includes a first conveyor belt 111 located below the paper stack storage area 601, and the first conveyor belt 111 is provided with a plurality of adsorption holes 112; a first baffle plate 610 is located on the front side of the paper stack storage area 601, and a channel is formed between the fourth baffle plate 640 and the first conveyor belt 111, the channel allowing multiple sheets of paper to pass through; the adsorption end of the vacuum adsorption assembly abuts against the lower surface of the first conveyor belt 111 at the paper stack storage area 601.

[0072] The first conveyor line 110 can move the paper along the first direction. The first conveyor belt 111 is provided with adsorption holes 112 and a paper stack storage area 601 is provided on the first conveyor belt 111. The paper stack storage area 601 can hold paper stacks. When the paper conveying mechanism is working, the paper stack storage area 601 contains paper stacks. Due to the obstruction of the first baffle plate 610, the paper stack can be restricted within the paper stack storage area 601. Under the action of the first conveyor belt 111, the first paper at the bottom of the paper stack can move forward with the first conveyor belt 111. After the first paper moves, the rear end of the second paper above the first paper comes into contact with the first conveyor belt 111 due to gravity. Then, under the action of the vacuum adsorption component, the rear end of the second paper can be firmly attached to the first conveyor belt 111. Under the action of the first conveyor belt 111, the second paper can move forward. At this time, the front end of the second paper is located above the rear end of the first paper. Furthermore, under the action of the vacuum adsorption component, the front end of the paper at the rear can be positioned above the rear end of the paper at the front, thereby achieving a stable fish-scale pattern of paper arrangement and output on the first conveyor belt 111.

[0073] In some embodiments of the present invention, in order to facilitate the passage of paper through the channel, the fourth baffle plate 640 is inclined and a channel is formed between the fourth baffle plate 640 and the first conveyor belt 111, and the height of the channel gradually increases along the direction close to the paper stack storage area 601.

[0074] A second elastic element, which can be a spring, is provided between the first stop plate 610 and the fourth stop plate 640. Furthermore, when dealing with thicker sheets of paper, the spring can contract upwards upon contact with the paper, allowing the fourth stop plate 640 to move upwards, increasing the height of the passage and ensuring that at least two sheets of paper can pass through simultaneously.

[0075] In some embodiments of the present invention, the blocking component 600 further includes a position adjustment component, which is drivenly connected to the first blocking plate 610 and the second blocking plate 620, and is capable of driving the first blocking plate 610 and the second blocking plate to move along a first direction and a second direction.

[0076] For paper of different sizes, the position adjustment component can control the first blocking plate 610 to move along the first direction and the second direction, and can adjust the first blocking plate 610 to move closer to or further away from the third blocking plate 630, so that the paper stack storage area 601 can accommodate paper stacks of different sizes, thereby expanding the applicability of the paper conveying mechanism; the second blocking plate 620 is located on the left side of the paper stack storage area 601. Under the action of the position adjustment component, the second blocking plate 620 can be controlled to move along the first direction and the second direction, thereby adjusting the size of the paper stack storage area 601 to accommodate paper stacks of different sizes, and improving the applicability of the paper conveying mechanism.

[0077] Specifically, the position adjustment assembly can consist of two lead screw and slider drive structures, which are respectively connected to the first stop plate 610 and the second stop plate 620.

[0078] Reference Figure 1 In some embodiments of the present invention, a feeding component 700 is also included. The feeding component 700 is disposed on one side of the first conveyor line 110 and is used to feed the paper stack to the paper stack storage area 601.

[0079] The feeding component 700 is used to feed paper stacks to the paper stack storage area 601 on the first conveyor line 110. The feeding component 700 can be located on the first side of the first conveyor line 110. The feeding component 700 can automatically feed paper stacks to the paper stack storage area 601 on the conveyor belt, saving time and effort.

[0080] Reference Figures 1 to 7 The paper feeding method according to the second aspect of this application, applied to the paper feeding device of the first aspect embodiment, includes the following steps:

[0081] S100: Place the corrugated paper on the first conveying component 100, and set the width direction of the corrugated paper in the same direction as the first direction;

[0082] S200, the corrugated paper is conveyed along the first direction by the first conveying component 100, and the corrugated paper is output from the first conveying component 100 to the third conveying line 210 located below the tail side of the first conveying component 100;

[0083] S300, the corrugated paper is conveyed along the second direction via the third conveyor line 210 and output to the fourth conveyor line 220 located at the tail side of the first conveyor component 100;

[0084] S400, the corrugated paper located on the fourth conveyor line 220 is pressed down by the pressing member 240, and the left and right sides of the corrugated paper located on the fourth conveyor line 220 are lifted by the two lifting members 230, so that the left and right sides of the corrugated paper are bent towards the middle.

[0085] S500, the fourth conveyor line 220 is controlled to move in the second direction by the second adjustment component;

[0086] S600, the corrugated paper is conveyed along the second direction through the fourth conveyor line 220, and the corrugated paper is output from the fourth conveyor line 220 to the fifth conveyor line 300 located at the tail side of the fourth conveyor line 220;

[0087] S700, corrugated paper is conveyed along the first direction via the fifth conveyor line 300.

[0088] Using the method of the second aspect embodiment described above, corrugated paper can be placed on the first conveying member 100, and the corrugated core paper interlayer of the corrugated paper is arranged to extend along the corrugated path in the length direction, so that the width direction of the corrugated paper is the first direction. The first conveying member 100 can convey the corrugated paper along the first direction and output the corrugated paper from the tail side of the first conveying member 100, so that the corrugated paper falls from the first conveying member 100 onto the third conveying line 210. The third conveying line 210 can receive the corrugated paper output from the first conveying member 100. Since corrugated paper is difficult to transport... The bending around the width ensures high safety when the first conveying component 100 outputs corrugated paper to the third conveying line 210. The third conveying line 210 outputs the corrugated paper from its tail side to the fourth conveying line 220. A gap exists between the pressing member 240 and the fourth conveying line 220. When the corrugated paper passes through the gap, the pressing member 240 can press down the middle portion of the corrugated paper. Since the lifting member 230 is positioned on both sides of the pressing member 240 along the first direction, the lifting member 230 can lift both sides of the corrugated paper through its lifting surface, thus ensuring that the two sides of the corrugated paper... The corrugated paper is bent laterally towards the middle portion, forming a crease extending along the second direction on the corrugated paper. After the fourth conveyor line 220 outputs the corrugated paper from the output end, the bent corrugated paper can reduce the degree of downward bending of the corrugated paper due to gravity along its length direction, and can also reduce the degree of bending of the portion of the corrugated paper outside the fourth conveyor line 220 relative to the portion inside the fourth conveyor line 220. When the fourth conveyor line 220 conveys the corrugated paper to the fifth conveyor line 300 located below the tail side of the fourth conveyor line 220, it can reduce the risk of the corrugated paper getting stuck on the fourth conveyor line. The second adjustment component can control the fourth conveyor 220 to move along a second direction when conveying different sizes of corrugated paper to the fifth conveyor 300, thereby adjusting the length of the fourth conveyor 220 extending directly above the fifth conveyor 300 so that the corrugated paper of each size falls to the middle position of the fifth conveyor 300, thereby improving the problem that the paper of each size is difficult to continue moving in the middle of the conveyor line when the conveying direction changes.
