The carton transverse pressing processing technology includes: when the paperboard is transported to a predetermined position, the paperboard is kept transporting, the mounting frame is translational rotated, and the transverse pressing cutter is kept facing the paperboard, the mounting frame drives the transverse pressing cutter to move towards the paperboard, and simultaneously drives the transverse pressing cutter to move along the transporting direction of the paperboard; when the transverse pressing cutter is pressed on the paperboard to a predetermined depth, the paperboard is kept transporting, the mounting frame is kept translational rotating, the transverse pressing cutter is moved away from the paperboard relative to the mounting frame, and the transverse pressing cutter is kept static relative to the paperboard.

[0005] Further, the translational rotation speed of the mounting frame is positively correlated with the transporting speed of the paperboard.

[0008] Further, the carton transverse pressing process further comprises: after the mounting frame moves and rotates in the direction away from the paperboard for a predetermined time, the transverse pressing knife separates from the paperboard, the mounting frame continues to rotate, and the next transverse pressing mark is processed in a cycle.

[0009] Further, the carton transverse pressing process further comprises: after the mounting frame moves to the position closest to the paperboard, the mounting frame moves and rotates in the direction away from the paperboard, and the transverse pressing knife moves away from the paperboard, the transverse pressing knife separates from the paperboard, the mounting frame continues to rotate, and the next transverse pressing mark is processed in a cycle.

[0010] Further, the paperboard is kept to be conveyed, and the movement speed of the transverse pressing knife in the conveying direction of the paperboard is the same as the conveying speed of the paperboard.

[0011] Further, the mounting frame is multiple, and at least two mounting frames are arranged in an up-down manner, and the carton transverse pressing process further comprises: the two mounting frames arranged in an up-down manner are arranged symmetrically in the plane where the paperboard is located and move symmetrically, so that the two mounting frames arranged in an up-down manner always maintain an up-down alignment relationship.

[0012] Further, the transverse pressing knife is multiple, and the two transverse pressing knives arranged in an up-down manner are arranged on the two mounting frames arranged in an up-down manner, and the carton transverse pressing process further comprises: the two transverse pressing knives arranged in an up-down manner are arranged symmetrically in the plane where the paperboard is located and move symmetrically, so that the two transverse pressing knives arranged in an up-down manner always maintain an up-down alignment relationship.

[0013] According to another aspect of the present application, a carton processing process is provided, which adopts a carton processing device, and the carton processing device comprises a feeding device, a transverse pressing device, a longitudinal pressing device, a transverse slotting device and a longitudinal cutting device, and the carton processing process comprises: transverse pressing mark processing, longitudinal pressing mark processing, transverse slotting processing and longitudinal cutting processing, and the transverse pressing mark processing is the above-mentioned carton transverse pressing process.

[0014] Further, the carton processing process further comprises: the feeding device conveys the paperboard to the transverse pressing device and performs the carton transverse pressing process to process the transverse pressing mark; the paperboard processed with the transverse pressing mark is conveyed to the longitudinal pressing device to process the longitudinal pressing mark; the paperboard processed with the longitudinal pressing mark is conveyed to the transverse slotting device to process the transverse slotting; and the paperboard processed with the transverse slotting is conveyed to the longitudinal cutting device to process the longitudinal cutting.

[0015] According to another aspect of the present application, there is provided a cross pressing device for a carton processing apparatus, for performing the carton cross pressing processing method as described above, the cross pressing device comprising: a frame; a driving assembly arranged on the frame, the driving assembly having a rotatable output; a mounting frame movably arranged relative to the frame, the mounting frame being drivingly coupled to the output, a geometric axis of the mounting frame being arranged eccentrically relative to a rotation axis of the mounting frame, the rotation axis of the mounting frame being coaxially arranged with the rotation axis of the output, the mounting frame being pivotally rotated about the rotation axis of the mounting frame; and a cross pressing assembly arranged on the mounting frame, the cross pressing assembly comprising a cross pressing blade, the cross pressing blade being kept with a blade edge thereof facing a paperboard to be processed when the mounting frame is pivotally rotated, the cross pressing blade being movable relative to the mounting frame towards or away from the paperboard.

[0016] By the processing method as described above, the paperboard does not need to be stopped when being cross pressed, continuous processing can be realized, thus greatly improving the processing efficiency, and the processing quality and processing quality of the cross pressing mark can be improved. Specifically, when cross pressing, the paperboard does not need to be stopped during conveying, the mounting frame is pivotally rotated during the conveying of the paperboard, the pivotally rotation of the mounting frame can be divided into two directions of transverse and longitudinal directions, the direction of the transverse direction is the same as the conveying direction of the paperboard, thus the transverse direction can make the mounting frame drive the cross pressing blade to move together with the paperboard, thus the mounting frame, the cross pressing blade and the paperboard keep synchronous movement along the conveying direction of the paperboard, and the three are relatively static, while the longitudinal direction can make the mounting frame drive the cross pressing blade to move towards the paperboard, thus the cross pressing blade can be pressed on the paperboard to form a cross pressing mark. Meanwhile, when the cross pressing blade presses the required cross pressing mark, the mounting frame continues to pivotally rotate, thus the cross pressing blade is moved upwards relative to the mounting frame to avoid further pressing, the upward movement of the cross pressing blade offsets the longitudinal movement of the mounting frame, thus the upward and downward positions of the cross pressing blade relative to the paperboard are unchanged, the cross pressing blade keeps static relative to the paperboard by the transverse movement of the mounting frame, thus the cross pressing blade keeps cross pressing for a period of time, and the mounting frame continues to pivotally rotate to drive the cross pressing blade to separate from the paperboard to complete the processing of the cross pressing mark. The above arrangement realizes continuous processing of the cross pressing of the paperboard, thus improving the processing efficiency, and the processing quality and processing quality of the cross pressing mark can be improved, and the overall structure of the device is simple, and the device is easy to use and operate.

DETAILED DESCRIPTION

[0024] It should be noted that the embodiments and the features in the embodiments in the present application can be combined with each other without conflict. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0025] It should be noted that, unless otherwise specified, all the technical and scientific terms used in the present application have the same meaning as that generally understood by the ordinary skilled in the art to which the present application belongs.

[0026] In the present application, unless otherwise specified, the orientation words such as "upper", "lower", "top", "bottom" are generally directed to the directions shown in the drawings, or are directed to the vertical, perpendicular or gravity directions of the components themselves; similarly, for the convenience of understanding and description, "inner" and "outer" refer to the inner and outer relative to the contour of the components themselves, but the above orientation words are not used to limit the present application.

[0027] In order to solve the problem of low processing and production efficiency of the carton in the prior art, the present application provides a carton transverse pressing processing process, a carton processing process and a transverse pressing device.

[0028] As Figure 1The paper box transverse pressing processing process adopts a transverse pressing device, the transverse pressing device comprises a mounting frame 30 capable of rotating in a horizontal translation around an eccentric axis and a transverse pressing cutter 51 movably arranged on the mounting frame 30, and the paper box transverse pressing processing process comprises the following steps: when the paperboard is conveyed to a predetermined position, the paperboard is kept conveying, the mounting frame 30 is rotated in a horizontal translation, and the transverse pressing cutter 51 is kept facing the paperboard; the mounting frame 30 drives the transverse pressing cutter 51 to move towards the paperboard, and simultaneously drives the transverse pressing cutter 51 to move along the conveying direction of the paperboard; when the transverse pressing cutter 51 is pressed on the paperboard to a predetermined depth, the paperboard is kept conveying, the mounting frame 30 is kept rotating in a horizontal translation, the transverse pressing cutter 51 is moved away from the paperboard relative to the mounting frame 30, and the transverse pressing cutter 51 is kept stationary relative to the paperboard.

[0029] The mounting frame 30 rotates in a horizontal translation during the conveying of the paperboard, the horizontal translation of the mounting frame 30 can be divided into horizontal-directional and longitudinal-directional sub-motions, the horizontal-directional sub-motion is in the same direction as the conveying direction of the paperboard, so that the horizontal-directional sub-motion can drive the mounting frame 30 to drive the transverse pressing cutter 51 to move together with the paperboard, so that the mounting frame 30, the transverse pressing cutter 51 and the paperboard keep synchronous motion in the conveying direction of the paperboard, and the three are kept stationary relative to each other, and the longitudinal-directional sub-motion can drive the mounting frame 30 to drive the transverse pressing cutter 51 to move towards the paperboard, so that the transverse pressing cutter 51 can be pressed on the paperboard to form a transverse pressing mark. Meanwhile, when the transverse pressing cutter 51 presses the required transverse pressing mark, the mounting frame 30 continues to rotate in a horizontal translation, so that the transverse pressing cutter 51 is driven to move upwards relative to the mounting frame 30 to avoid further pressing of the transverse pressing cutter 51, the upward motion of the transverse pressing cutter 51 offsets the longitudinal-directional sub-motion of the mounting frame 30, so that the upward and downward positions of the transverse pressing cutter 51 relative to the paperboard are kept unchanged, the horizontal-directional sub-motion of the mounting frame 30 keeps the transverse pressing cutter 51 stationary relative to the paperboard, so that the transverse pressing cutter 51 keeps pressing for a period of time, and the mounting frame 30 continues to rotate in a horizontal translation to drive the transverse pressing cutter 51 to move away from the paperboard to complete the processing of the transverse pressing mark. The above arrangement realizes continuous processing of the transverse pressing of the paperboard, so that the processing efficiency is improved, and the processing quality and processing quality of the transverse pressing mark are improved, and the overall structure of the device is simple, and the device is convenient to use and operate.

[0030] It should be noted that the transverse pressing in the embodiment refers to pressing a mark on the surface of the paperboard, and the length direction of the mark is perpendicular to the length direction of the paperboard and parallel to the width direction of the paperboard. Since the conveying direction of the paperboard is generally the same as the length direction of the paperboard, the length direction of the mark is perpendicular to the conveying direction of the paperboard. Considering that the paperboard is generally conveyed in a flat transverse manner, the transverse pressing knife 51 in the embodiment is arranged to move up and down relative to the paperboard, so that the transverse pressing knife 51 can form a transverse pressing mark on the surface of the paperboard. For ease of explanation, the transverse pressing knife 51 above the paperboard is taken as an example for description, and the transverse pressing knife 51 forms a transverse pressing mark on the paperboard by moving downward. Of course, the transverse pressing knife 51 can also be arranged below the paperboard, and the upward and downward movement directions of the transverse pressing knives 51 above and below are opposite.

[0031] For the translational rotation of the mounting frame 30, the geometric axis of the mounting frame 30 is not consistent with the rotation axis thereof, so that the rotation of the mounting frame 30 is essentially eccentric rotation, and the translation refers to that the overall state of the mounting frame 30 remains unchanged during the rotation movement, and does not tilt, twist or the like, that is, the rotation of the mounting frame 30 is not overall overturning, but is translational rotation that maintains the state of the mounting frame 30. Since the mounting frame 30 in the embodiment mainly adopts a standing plate-shaped member, the translation is that the mounting frame 30 maintains the standing state during rotation, and does not tilt or bend or the like. For the rotation track of the mounting frame 30, the rotation track line at most positions thereof is not a true circle, but is similar to an ellipse. The geometric axis of the mounting frame 30 in the embodiment refers to the geometric center line in the length direction of the mounting frame 30, that is, the horizontal geometric center line, and the geometric axis of the eccentric wheel refers to the geometric center line parallel to the rotation axis of the eccentric wheel.

[0032] In the embodiment, the translational rotation speed of the mounting frame 30 is positively correlated with the conveying speed of the paperboard. The faster the translational rotation speed of the mounting frame 30, the faster the horizontal component movement speed, so that the translational rotation of the mounting frame 30 can match the conveying speed of the paperboard, and the reliability of the horizontal relative static state between the transverse pressing knife 51 and the paperboard is ensured.

[0033] Similarly, the speed of the movement of the cross-cutting knife 51 relative to the mounting frame 30 is positively correlated with the translational rotation speed of the mounting frame 30. Here, the movement of the cross-cutting knife 51 relative to the mounting frame 30 refers to the up-and-down movement of the cross-cutting knife 51 itself. The faster the translational rotation speed of the mounting frame 30, the faster the longitudinal component movement of the mounting frame 30, and the faster the movement of the cross-cutting knife 51 relative to the mounting frame 30 needs to be, so as to ensure that the upward movement of the cross-cutting knife 51 is offset by the downward longitudinal component movement of the mounting frame 30, thereby ensuring the reliability of the longitudinal relative static state between the cross-cutting knife 51 and the paperboard. The specific movement parameters of the mounting frame 30, the cross-cutting knife 51, and the like can be adjusted according to the attribute parameters of the paperboard, as long as the effect of keeping the cross-cutting knife 51 relatively static with the paperboard during cross-cutting can be achieved.

[0034] In the embodiment, the carton cross-cutting process further includes: after the mounting frame 30 moves to the position closest to the paperboard, the mounting frame 30 is translational rotated in a direction away from the paperboard, the cross-cutting knife 51 is moved relative to the mounting frame 30 in a direction close to the paperboard, and the cross-cutting knife 51 is static relative to the paperboard. Specifically, as the mounting frame 30 is continuously translational rotated, the mounting frame 30 is translational rotated to the lowest position, at which time the cross-cutting knife 51 is moved upward to the highest position relative to the mounting frame 30, and then the mounting frame 30 is continuously translational rotated in a direction upward, which drives the cross-cutting knife 51 to move in a direction away from the paperboard. In order to further ensure the quality of the cross-cutting mark, the cross-cutting knife 51 is moved downward relative to the mounting frame 30 when the mounting frame 30 is translational rotated upward, so that the downward movement of the mounting frame 30 is offset by the upward longitudinal component movement of the mounting frame 30, and the cross-cutting knife 51 continues to be pressed on the paperboard and keeps static relative to the paperboard for a period of time. This can effectively prolong the pressing time and improve the processing quality of the cross-cutting mark.

[0035] In the embodiment, the carton cross-cutting process further includes: after the mounting frame 30 is translational rotated in a direction away from the paperboard for a predetermined time, the cross-cutting knife 51 is separated from the paperboard, the mounting frame 30 is continuously rotated, and the next cross-cutting mark is processed in a cycle. The specific value of the predetermined time can be set according to the needs and the movement range of the mounting frame 30. In this way, during the entire processing process, the paperboard is continuously conveyed for continuous processing, and the mounting frame 30 is continuously translational rotated in one direction without reciprocating movement. After the mounting frame 30 passes through the highest position of the movement, the mounting frame 30 can be moved in a direction close to the paperboard, and then the mounting frame 30 can be moved in a direction transverse to the conveying direction of the paperboard after passing through the horizontal plane where the rotation axis is located, so that the mounting frame 30 can repeat the previous actions to process the next cross-cutting mark on the paperboard, and the processing of the cross-cutting mark can be continuously and efficiently performed in a cycle, thereby greatly improving the processing efficiency and achieving high-speed processing.

[0036] In an embodiment not shown, the above-mentioned mode can not be adopted, and after the mounting frame 30 is horizontally rotated to pass the lowest position, it directly drives the transverse pressing knife 51 to move upward to make the transverse pressing knife 51 separate from the paperboard to complete the transverse pressing. At this time, the carton transverse pressing processing technology further comprises the following steps: after the mounting frame 30 moves to the position closest to the paperboard, i.e. the lowest position, the mounting frame 30 is horizontally rotated to move away from the paperboard, and drives the transverse pressing knife 51 to move away from the paperboard, the transverse pressing knife 51 separates from the paperboard, and the mounting frame 30 continues to rotate, and the position of the transverse pressing knife 51 relative to the mounting frame 30 is adjusted and reset during the horizontal rotation of the mounting frame 30, so that the next transverse pressing mark can be processed in circulation.

[0037] In this embodiment, the paperboard is always conveyed during the whole process, and the movement speed of the transverse pressing knife 51 along the conveying direction of the paperboard, i.e. the speed of the horizontal movement of the mounting frame 30, is the same as the conveying speed of the paperboard, so as to ensure that the movement speed of the transverse pressing knife 51 and the paperboard in the conveying direction of the paperboard is matched.

[0038] Optionally, the mounting frame 30 is provided in multiple numbers, and at least two mounting frames 30 are arranged above and below, and in this embodiment, two mounting frames 30 are arranged above and below in alignment, and are respectively located on the upper and lower sides of the paperboard. The carton transverse pressing processing technology further comprises the following steps: the two mounting frames 30 arranged above and below are arranged symmetrically with respect to the plane where the paperboard is located and are symmetrically moved, i.e. when the mounting frame 30 above the paperboard moves downward, the mounting frame 30 below the paperboard moves upward, the moving directions of the longitudinal movements of the two are opposite, and the speeds are the same, and the horizontal movements are the same due to the same conveying direction of the paperboard, so that the directions and speeds of the horizontal movements of the two are the same, thereby making the two mounting frames 30 arranged above and below always maintain the alignment relationship.

[0039] In addition to the mounting frame 30 being provided in multiple numbers, the transverse pressing knife 51 of this embodiment is also provided in multiple numbers, and the two mounting frames 30 arranged above and below are each provided with a transverse pressing knife 51. Since this embodiment is provided with two mounting frames 30, the transverse pressing knife 51 is also provided in two numbers, and the two transverse pressing knives 51 are respectively arranged on the two mounting frames 30 arranged above and below, so as to form a one-to-one corresponding relationship between the mounting frame 30 and the transverse pressing knife 51. Based on the above-mentioned arrangement mode, the carton transverse pressing processing technology of this embodiment further comprises the following steps: the two transverse pressing knives 51 arranged above and below are arranged symmetrically with respect to the plane where the paperboard is located and are symmetrically moved, i.e. when the transverse pressing knife 51 above the paperboard moves downward, the transverse pressing knife 51 below the paperboard moves upward, the moving directions of the longitudinal movements of the two are opposite, and the speeds are the same, and the horizontal movements are driven by the mounting frame 30, so that under the condition that the horizontal movements of the two mounting frames 30 are the same, the moving directions and speeds of the two transverse pressing knives 51 are also the same, thereby making the two transverse pressing knives 51 arranged above and below always maintain the alignment relationship, and both can be conveyed together with the paperboard, and can also realize the processing of the transverse pressing mark.

[0040] Of course, the arrangement and movement of the mounting frames 30 and the arrangement and movement of the cross-cutting knives 51 are not limited to the above-mentioned manners in the embodiment, and the mounting frames 30 and the cross-cutting knives 51 can also be arranged and moved alternately, for example, the mounting frames 30 are not aligned vertically but staggered along the conveying direction of the paperboard, and the vertical movement speeds of the two mounting frames 30 can be different, so that the two mounting frames 30 can be kept in cooperation during the cross-cutting of the cross-cutting knives 51. Moreover, the movement speeds of the mounting frames 30 and the cross-cutting knives 51 are not necessarily the same throughout the movement, and the movement speeds of the mounting frames 30 and the cross-cutting knives 51 can be adjusted in different states, for example, the speed of the mounting frames 30 during the horizontal movement and rotation is matched with the conveying speed of the paperboard, and the mounting frames 30 can rotate faster during the subsequent rotation after the cross-cutting is completed, so that the processing of two close cross-cutting marks can be realized.

[0041] The embodiment also provides a carton processing technology, which adopts the carton processing device, and the carton processing device includes a feeding device, a cross-cutting device, a longitudinal-cutting device, a horizontal slotting device, a longitudinal-cutting device, and a punching device. The carton processing technology includes cross-cutting mark processing, longitudinal-cutting mark processing, horizontal slotting processing, and longitudinal-cutting processing, and the cross-cutting mark processing is the above-mentioned carton cross-cutting processing technology.

[0042] The above-mentioned carton processing technology specifically includes that the feeding device conveys the paperboard to the cross-cutting device and performs the above-mentioned carton cross-cutting processing technology to perform the cross-cutting mark processing; the paperboard on which the cross-cutting mark processing is completed is conveyed to the longitudinal-cutting device to perform the longitudinal-cutting mark processing; the paperboard on which the longitudinal-cutting mark processing is completed is conveyed to the horizontal slotting device to perform the horizontal slotting processing; the paperboard on which the horizontal slotting processing is completed is conveyed to the longitudinal-cutting device to perform the longitudinal-cutting processing; and the paperboard on which the longitudinal-cutting processing is completed is conveyed to the punching device to perform the punching processing. The carton processing technology of the embodiment sequentially performs the cross-cutting mark processing, the longitudinal-cutting mark processing, the horizontal slotting processing, the longitudinal-cutting processing, and the punching processing, and the paperboard is continuously conveyed during the whole process to realize high-speed processing. Of course, the sequence of the above-mentioned cross-cutting mark processing, longitudinal-cutting mark processing, horizontal slotting processing, longitudinal-cutting processing, and punching processing is not specially required, and the sequence can be adjusted, and the specific selection of the processing technology can also be adjusted as required, and part of the processing can be omitted or other processing processes can be added, for example, the horizontal-cutting processing is added, and the longitudinal-cutting processing is omitted.

[0043] As Figures 2 to 4As shown, the embodiment also provides a cross pressing device for a carton processing equipment, for performing the cross pressing processing procedure of the above, the cross pressing device comprises a frame 10, a driving assembly 20, a mounting frame 30 and a cross pressing assembly 50, the driving assembly 20 is arranged on the frame 10, the driving assembly 20 has a rotatable output 25; the mounting frame 30 is movably arranged relative to the frame 10, the mounting frame 30 is drivingly matched with the output 25, a geometric axis of the mounting frame 30 is arranged eccentric to a rotation axis of the mounting frame 30, the rotation axis of the mounting frame 30 is coaxially arranged with the rotation axis of the output 25, the mounting frame 30 rotates in translation around the rotation axis of the mounting frame 30; the cross pressing assembly 50 is arranged on the mounting frame 30, the cross pressing assembly 50 comprises a cross pressing knife 51, the mounting frame 30 rotates in translation to keep a blade of the cross pressing knife 51 facing the paperboard to be processed, the cross pressing knife 51 is movable relative to the mounting frame 30 towards or away from the paperboard.

[0044] The above arrangement can make the mounting frame 30 rotate in translation around the rotation axis eccentric to the geometric axis, on one hand, the rotating mode in translation can ensure that the cross pressing knife 51 on the mounting frame 30 can always face the paperboard, thereby ensuring the pressing effect of the cross pressing knife 51 on the paperboard, on the other hand, the mounting frame 30 can drive the cross pressing knife 51 to move, thereby making the cross pressing knife 51 not only continuously approach the paperboard to form a cross pressing mark on the paperboard, but also move with the paperboard to continuously process the carton without stopping. Meanwhile, the cross pressing knife 51 can also move relative to the mounting frame 30, so that the cross pressing knife 51 can adjust its position while being driven by the mounting frame 30 to move, i.e. when the mounting frame 30 drives the cross pressing knife 51 to press on the paperboard, the continuous rotation of the mounting frame 30 can cause the cross pressing knife 51 to have an excessively deep pressing mark, so that the cross pressing knife 51 can adjust its position relative to the mounting frame 30 at this time, i.e. the cross pressing knife 51 moves away from the paperboard, while the mounting frame 30 continues to move towards the paperboard, the two movements cancel each other out, so that the cross pressing knife 51 can remain stationary relative to the paperboard, thereby making the cross pressing knife 51 remain pressed on the paperboard for a period of time, thereby ensuring the cross pressing effect, and since the rotation of the mounting frame 30 has a component along the conveying direction of the paperboard, the paperboard can be continuously processed without stopping, thereby realizing continuous production.

[0045] As Figure 3As shown, in the present embodiment, the output member 25 is a first rotating wheel, the mounting frame 30 comprises an intermediate member, the first rotating wheel has a transmission surface, and the intermediate member is in contact with the transmission surface. Since the distances from different positions of the transmission surface to the rotating axis of the first rotating wheel are not completely same, as the first rotating wheel rotates, the intermediate member is in contact with different positions of the transmission surface, so that the intermediate member performs a translational rotation, which can generate horizontal and vertical component motions, thereby driving the horizontal pressure cutter 51 to perform horizontal and vertical component motions.

[0046] In the present embodiment, the intermediate member is a wheel sleeve 31, which is sleeved on the outside of the first rotating wheel, and the intermediate member is in the same axial direction as the first rotating wheel. The first rotating wheel is a first eccentric wheel, and the outer circumferential surface thereof serves as the transmission surface. The rotating axis of the first eccentric wheel is eccentrically arranged relative to the geometric axis of the first eccentric wheel. In this way, when the first eccentric wheel drives the intermediate member to rotate, the mounting frame 30 can be driven by the intermediate member to perform a translational rotation. Specifically, when the geometric axis of the first eccentric wheel rotates below the rotating axis of the first eccentric wheel, the wheel sleeve 31 drives the mounting frame 30 to rotate to the closest distance from the paperboard, and the processing of the horizontal pressure mark is completed. The first eccentric wheel continues to rotate, so that the wheel sleeve 31 drives the horizontal pressure cutter 51 to move away from the paperboard, and the processed paperboard is kept to be conveyed forward.

[0047] The horizontal pressure assembly 50 in the present embodiment is multiple. In the present embodiment, two horizontal pressure assemblies 50 are provided, which are a first horizontal pressure assembly 50 and a second horizontal pressure assembly 50. The first horizontal pressure assembly 50 and the second horizontal pressure assembly 50 are basically the same in structure except that the structures of the ends of the horizontal pressure cutter 51 are different. Therefore, the following description about the horizontal pressure driving part 52, the second rotating wheel 53, and the horizontal pressure transmission part 54 will not be described again.

[0048] As shown in FIG. 6, the horizontal pressure driving part 52 comprises a horizontal pressure driving motor 521, a horizontal pressure driving belt 522, and a horizontal pressure driving pulley 523. The horizontal pressure driving motor 521 is arranged on the mounting frame 30, and the horizontal pressure driving belt 522 is arranged on the horizontal pressure driving pulley 523. The horizontal pressure driving belt 522 is in contact with the horizontal pressure driving pulley 523 and the second rotating wheel 53. Figure 4As shown, the cross-pressure assembly 50 of the embodiment further comprises a cross-pressure driving part 52, a second rotating wheel 53, and a cross-pressure transmission part 54. The cross-pressure driving part 52 is fixed on the mounting rack 30 by a seat or the like structure, thereby achieving the mounting and fixing of the whole assembly. The second rotating wheel 53 is drivingly connected with the cross-pressure driving part 52, and has a connection with the cross-pressure driving part 52. The distance from different positions on the outer circumferential surface of the second rotating wheel 53 to the connection is not completely the same. The connection between the second rotating wheel 53 and the cross-pressure driving part 52 is the rotation center of the second rotating wheel 53. The cross-pressure transmission part 54 abuts against the outer circumferential surface of the second rotating wheel 53, thereby enabling the cross-pressure transmission part 54 to move up and down under the driving of the second rotating wheel 53. The cross-pressure transmission part 54 is connected with the first cross-pressure knife 51, thereby enabling the second rotating wheel 53 to drive the first cross-pressure knife 51 to move up and down. Specifically, with the rotation of the second rotating wheel 53, different positions on the outer circumferential surface of the second rotating wheel 53 abut against the cross-pressure transmission part 54. When the position on the second rotating wheel 53 abutting against the cross-pressure transmission part 54 is farthest from the rotation center of the second rotating wheel 53, the distance between the first cross-pressure knife 51 and the second cross-pressure knife 51 is smallest, and the cross-pressure mark processing is completed. After the processing is completed, the second rotating wheel 53 continues to rotate, the position on the second rotating wheel 53 abutting against the cross-pressure transmission part 54 changes, the distance between the abutting position and the rotation center of the second rotating wheel 53 decreases, the cross-pressure transmission part 54 of the first cross-pressure assembly 50 moves upward, the cross-pressure transmission part 54 of the second cross-pressure assembly 50 moves downward, and the gap between the first cross-pressure knife 51 and the second cross-pressure knife 51 becomes larger.

[0049] In the embodiment, the second rotating wheel 53 is a second eccentric wheel, and the connection between the second eccentric wheel and the cross-pressure driving part 52 is eccentrically arranged relative to the geometric center of the second eccentric wheel. In this way, the cross-pressure driving part 52 drives the second eccentric wheel to rotate. When the geometric center of the second eccentric wheel of the first cross-pressure knife 51 rotates to the lower side of the rotation center of the second eccentric wheel thereof, and the geometric center of the second eccentric wheel of the second cross-pressure knife 51 rotates to the upper side of the rotation center of the second eccentric wheel thereof, the distance between the geometric centers of the two second eccentric wheels is smallest, thereby the gap between the first cross-pressure knife 51 and the second cross-pressure knife 51 is smallest, and the cross-pressure knife 51 extrudes the paperboard, and the cross-pressure mark processing is completed.

[0050] In the embodiment, the cross-pressure driving part 52 comprises a cross-pressure driving member 521 and a cross-pressure transmission shaft 522. The cross-pressure driving member 521 can be a motor. The cross-pressure transmission shaft 522 extends along the length direction of the first cross-pressure cutter 51. The cross-pressure transmission shaft 522 is drivingly connected with the cross-pressure driving member 521. The second rotating wheel 53 is sleeved outside the cross-pressure transmission shaft 522 and is synchronously driven with the cross-pressure transmission shaft 522. In this way, the motor can drive the second rotating wheel 53 to perform eccentric rotation through the cross-pressure transmission shaft 522. The cross-pressure transmission part 54 comprises a cross-pressure wheel sleeve 541 and a cross-pressure connecting member 542. The cross-pressure wheel sleeve 541 is sleeved outside the second rotating wheel 53. The inner diameter of the cross-pressure wheel sleeve 541 is substantially the same as the outer diameter of the second rotating wheel 53. In this way, the second rotating wheel 53 can drive the cross-pressure wheel sleeve 541 to perform up-down movement when the second rotating wheel 53 rotates. The cross-pressure wheel sleeve 541 is connected with the first cross-pressure cutter 51 or the second cross-pressure cutter 51 through the cross-pressure connecting member 542. Therefore, the cross-pressure wheel sleeve 541 can drive the first cross-pressure cutter 51 or the second cross-pressure cutter 51 to perform up-down movement when the cross-pressure wheel sleeve 541 performs up-down movement, thereby realizing the cross-pressure effect of the cross-pressure cutter 51 on the paperboard. Considering that the cross-pressure wheel sleeve 541 can also move laterally in addition to up-down movement, in order to avoid the lateral movement of the cross-pressure wheel sleeve 541 causing the lateral movement of the cross-pressure cutter 51, the cross-pressure connecting member 542 is provided with a guide rail between the mounting frame 30. The guide rail extends upward and downward, thereby enabling the cross-pressure connecting member 542 to only move up and down, and further ensuring that the cross-pressure cutter 51 can only move up and down. Meanwhile, the embodiment is also provided with a protruding section on the outer circumferential side of the cross-pressure wheel sleeve 541. The protruding section is hingedly connected with the cross-pressure connecting member 542, thereby enabling the protruding section and the cross-pressure connecting member 542 to relatively rotate. In this way, the cross-pressure wheel sleeve 541 can only drive the cross-pressure connecting member 542 to move up and down, thereby ensuring the stable and reliable movement of the cross-pressure cutter 51.

[0051] In the embodiment, considering that the length of the cross-pressure transmission shaft 522 is relatively long, the embodiment is also provided with a support member. The support member can be connected with the mounting frame 30. The cross-pressure transmission shaft 522 is sleeved and supported on the support member, thereby realizing the support of the transmission shaft. Bearings or other components can be arranged between the cross-pressure transmission shaft 522 and the support member as needed, thereby ensuring the smooth rotation of the cross-pressure transmission shaft 522. At this time, in addition to being matched with the mounting frame 30 through the guide rail, the cross-pressure connecting member 542 can also be matched with the support member through the guide rail, thereby also being able to limit the cross-pressure connecting member 542 to only move up and down.
