Description

Technical Field

[0001] The invention relates to a corrugated paper conveying device and method, and in particular to a corrugated paper precise conveying device and method. Background Art

[0002] In the automatic production process of corrugated paperboard, an automatic conveying device is required to convey corrugated paper. For example, the Chinese invention patent with the authorization announcement number CN109292488B discloses a multi-specification paperboard transmission and feeding device for a corrugated paperboard printing machine. The device includes a belt feeding mechanism and a suction feeding mechanism that synchronously and cooperatively convey the paperboard. The belt feeding mechanism is provided with a gap adjustment component, and the lower parts of the belt feeding mechanism and the suction feeding mechanism are provided with a distance adjustment mechanism. The device can minimize the damage of corrugated paperboard, ensure the quality of subsequent printing, and effectively reduce energy consumption and save printing costs.

[0003] However, the above-mentioned paper feeding device still has the following shortcomings:

[0004] Although a suction paper feeding mechanism is provided between the two belt paper feeding mechanisms for supporting and conveying, for larger-sized corrugated paper, a larger portion is still suspended in the air, namely, the portion between the suction paper feeding mechanism and the belt paper feeding mechanism; and the two belt paper feeding mechanisms are only responsible for conveying forward and cannot adjust the posture of the corrugated paper, so during the conveying process, this portion may bulge or collapse, thereby reducing the accuracy of conveying and affecting the quality of subsequent printing. Summary of the invention

[0005] The purpose of the present invention is to overcome the above-mentioned problems and provide a corrugated paper precision conveying device, which can flatten the corrugated paper during the conveying process to prevent the occurrence of arching or collapsing, which is conducive to improving the accuracy of conveying and obtaining better printing quality.

[0006] Another object of the present invention is to provide a method for accurately conveying corrugated paper.

[0007] The purpose of the present invention is achieved through the following technical solutions:

[0008] A corrugated paper precision conveying device, comprising a belt paper feeding mechanism, a suction paper feeding mechanism, a distance adjustment mechanism, and a straightening power mechanism for causing the belt paper feeding mechanism to pull the corrugated paper away from the suction paper feeding mechanism;

[0009] The distance adjustment mechanism includes an adjustment drive motor and an adjustment transmission assembly; the adjustment transmission assembly includes an adjustment screw and an adjustment screw nut; the adjustment screw is connected to the adjustment drive motor through an axially movable follower connection structure;

[0010] The straightening power mechanism comprises a straightening drive motor and a straightening transmission assembly; the straightening transmission assembly comprises a cam, a straightening transmission plate, a straightening spring, a straightening push plate and a screw rod assembly; the axis of the cam is vertically arranged, and the cam is connected to the straightening drive motor; the straightening push plate is connected to the frame of the suction paper feeding mechanism through a transverse guide structure; the straightening transmission plate is provided with a sliding portion which is laterally movably connected to the straightening push plate; the straightening spring is sleeved on the sliding portion, and the two ends of the straightening spring are respectively pressed against the straightening transmission plate and the straightening push plate; the screw rod assembly comprises a straightening screw and a straightening screw rod nut which cooperates with the straightening screw rod, one end of the straightening screw rod is rotatably connected to the straightening push plate; the straightening screw rod nut is fixedly arranged at the bottom of the belt paper feeding mechanism; the straightening screw rod is parallel to the adjusting screw rod, and the rotation direction of the straightening screw rod is opposite to that of the adjusting screw rod; a linkage structure is provided between the straightening screw rod and the adjusting screw rod.

[0011] A preferred embodiment of the present invention, wherein the follower connection structure is connected to the adjusting drive motor via a reversing transmission structure, the reversing transmission structure comprises a driving bevel gear and a driven bevel gear; the driving bevel gear is coaxially fixedly connected to the output shaft of the adjusting drive motor; the driven bevel gear is fixedly connected to the follower connection structure.

[0012] Further, the follower connection structure includes a mounting plate, a follower seat and a follower spring;

[0013] The mounting plate is fixedly connected to the driven bevel gear; the mounting plate is provided with a mounting inner cavity, and a plurality of mounting parts are provided in the mounting inner cavity;

[0014] The follower seat is arranged in the mounting inner cavity, and the follower seat is slidably connected to the mounting portion; one end of the adjusting screw rod is fixedly connected to the follower seat, and the axis of the adjusting screw rod is parallel to the sliding direction of the follower seat;

[0015] The follower spring is sleeved on the mounting portion, and two ends of the follower spring are respectively pressed against the follower seat and the outer end of the mounting portion.

[0016] Through the above structure, in the process of conveying, in order to avoid interference, the belt paper feeding mechanism will pull the adjusting screw rod to move horizontally, and the adjusting screw rod will drive the follower seat to move, thereby compressing the follower spring to achieve movement compensation; after the conveying work is completed, the follower spring releases potential energy to restore the deformation and drives the follower seat to reset. In this way, it can ensure the smooth completion of the straightening work without hindering the adjustment work, which is very clever.

[0017] Furthermore, the driven bevel gears are provided with two and are arranged opposite to each other; the adjusting screw rods are provided with two groups and are arranged opposite to each other; the belt paper feeding mechanism is provided with two groups and is respectively located on both sides of the air suction paper feeding mechanism;

[0018] The adjusting transmission assembly and the straightening transmission assembly are each provided with two groups which are arranged opposite to each other; the two groups of straightening transmission assemblies share a cam.

[0019] Furthermore, each group of adjusting screw rods includes two adjusting screw rods, and the two adjusting screw rods in the same group are connected via a synchronous transmission structure.

[0020] Further, the straightening drive motor is composed of an adjustment drive motor;

[0021] The straightening power mechanism also includes a lifting drive mechanism, which includes a lifting plate and a lifting drive cylinder, the adjusting drive motor is arranged on the lifting plate, the cylinder body of the lifting drive cylinder is fixed on the frame of the air suction and paper feeding mechanism, and the telescopic rod of the lifting drive cylinder is fixedly connected to the lifting plate. Through the above structure, under the drive of the lifting drive cylinder, the working mode is switched, so that the active bevel gear is meshed with the driven bevel gear, or the cam is moved to the front of the straightening transmission plate, so that one motor can be shared, which is conducive to simplifying the structure and reducing costs.

[0022] A preferred embodiment of the present invention, wherein the transverse guide structure includes a transverse guide column and a first transverse guide sleeve; one end of the transverse guide column is fixedly connected to the straightening push plate; the first transverse guide sleeve is fixedly arranged on the frame of the suction paper feeding mechanism.

[0023] Furthermore, the belt paper feeding mechanism is provided with a second transverse guide sleeve; the transverse guide post cooperates with the second transverse guide sleeve.

[0024] In a preferred embodiment of the present invention, the linkage structure comprises a linkage belt and a linkage pulley, two linkage pulleys are provided and are respectively arranged on the straightening screw and the adjusting screw, and the linkage belt is connected between the two linkage pulleys.

[0025] Furthermore, a limit sliding structure is provided between the straightening screw and the corresponding linkage pulley, the limit sliding structure comprising a limit sliding part and a limit sliding groove cooperating with the limit sliding part, the limit sliding part is provided on the linkage pulley; the limit sliding groove is provided on the straightening screw, and the limit sliding groove extends in a direction parallel to the axis of the straightening screw. Through the above structure, not only can the straightening screw slide relative to the corresponding linkage pulley during the straightening process to complete the straightening work, but also the circumferential direction limit can be provided for the straightening screw during the distance adjustment work, so as to drive the straightening screw to rotate.

[0026] A method for accurately conveying corrugated paper comprises the following steps:

[0027] The corrugated paper is conveyed synchronously by the belt paper feeding mechanism and the air suction paper feeding mechanism;

[0028] The cam is driven to rotate by the straightening drive motor; when the protruding part of the cam contacts the straightening transmission plate, the straightening transmission plate is driven to move in the direction of the straightening push plate, at which time the straightening spring is compressed and deformed, and the force generated by the compression directly acts on the straightening push plate;

[0029] If the corrugated paper on the belt paper feeding mechanism is arched or collapsed, the force generated by the compression of the straightening spring will adaptively drive the straightening push plate close to the belt paper feeding mechanism, so that the straightening screw drives the belt paper feeding mechanism to move slightly and adaptively horizontally to straighten the corrugated paper;

[0030] If the corrugated paper on the belt paper feeding mechanism does not bulge or collapse, and the tensile stress of the corrugated paper is greater than the force generated by the compression of the straightening spring, the straightening spring cannot drive the straightening push plate to move, but remains in a compressed state, causing the straightening push plate to have a tendency to move toward the belt paper feeding mechanism;

[0031] During the conveying process, the straightening drive motor keeps driving the cam to rotate cyclically; when the corrugated paper comes onto the current belt paper feeding mechanism, the protruding part of the cam just presses against the straightening transmission plate; when the corrugated paper leaves the current belt paper feeding mechanism, the protruding part of the cam also moves away from the straightening transmission plate, and at this time the straightening transmission plate is reset under the action of the straightening spring;

[0032] When the belt paper feeding mechanism moves laterally, the adjusting screw rod is pulled to move synchronously, and the follower connection structure provides lateral movement compensation.

[0033] A preferred embodiment of the present invention is that when the distance is adjusted, the adjusting screw is driven to rotate by the adjusting drive motor, and the power is transmitted to the straightening screw through the linkage structure. The straightening screw rotates in the opposite direction to avoid the belt paper feeding mechanism, so that the belt paper feeding mechanism moves along the straightening screw to complete the distance adjustment.

[0034] Compared with the prior art, the present invention has the following beneficial effects:

[0035] 1. The accurate corrugated paper conveying device of the present invention can flatten the corrugated paper during conveying to prevent the corrugated paper from bulging or collapsing, which is beneficial to improving the conveying accuracy and obtaining better printing quality.

[0036] 2. The adjusting screw is connected to the adjusting drive motor through an axially movable follower connection structure. When the belt paper feeding mechanism moves laterally, it will pull the adjusting screw to move synchronously. The follower connection structure provides lateral movement compensation, which allows the straightening work to proceed smoothly without affecting the distance adjustment. It is very clever.

[0037] 3. When adjusting the distance, the adjusting screw will drive the straightening screw to rotate synchronously through the linkage structure to prevent the straightening screw from blocking the belt paper feeding mechanism, so that the belt paper feeding mechanism can move along the straightening screw to ensure that the distance adjustment work is completed smoothly.

[0055] See also Figure 2-3 The linkage structure includes a linkage belt 18 and a linkage pulley 19 .

[0057] See also Figure 1-5 The method for accurately conveying corrugated paper in this embodiment comprises the following steps:

[0058] The corrugated paper is conveyed synchronously by the belt paper feeding mechanism 1 and the air suction paper feeding mechanism 2.

[0059] The cam 6 is driven to rotate by the straightening drive motor 5; when the protruding part of the cam 6 contacts the straightening transmission plate 7, the straightening transmission plate 7 is driven to move in the direction of the straightening push plate 9, and the straightening spring 8 is compressed and deformed at this time, and the force generated by the compression directly acts on the straightening push plate 9. If the corrugated paper on the belt paper feeding mechanism 1 is arched or collapsed, the force generated by the compression of the straightening spring 8 will adaptively drive the straightening push plate 9 to approach the belt paper feeding mechanism 1, so that the straightening screw 10 drives the belt paper feeding mechanism 1 to move slightly and adaptively in the lateral direction, thereby adaptively straightening the corrugated paper to prevent the occurrence of arching or collapsing, which is conducive to improving the accuracy of transportation and obtaining better printing quality. If the corrugated paper on the belt paper feeding mechanism 1 does not arch or collapse, that is, the posture of the corrugated paper is straight, and the tensile stress of the corrugated paper is greater than the force generated by the compression of the straightening spring 8, then the straightening spring 8 cannot drive the straightening push plate 9 to move, but remains in a compressed state, causing the straightening push plate 9 to generate a tendency to move toward the direction of the belt paper feeding mechanism 1, thereby achieving flexible straightening without damaging the corrugated paper.

[0060] During the conveying process, the straightening drive motor 5 will keep driving the cam 6 to rotate in a cycle. When the corrugated paper comes to the current belt paper feeding mechanism 1, the protruding part of the cam 6 just hits the straightening transmission plate 7; when the corrugated paper leaves the current belt paper feeding mechanism 1, the protruding part of the cam 6 also moves away from the straightening transmission plate 7, and the straightening transmission plate 7 is reset under the action of the straightening spring 8. Further, in practical applications, the rotation speed of the cam 6 can be adjusted according to the conveying speed of the corrugated paper, so that the rotation of the cam 6 and the conveying of the corrugated paper are just in sync, forming a one-to-one corresponding conveying rhythm; or a sensor for detecting the corrugated paper can be set. When it is detected that the corrugated paper is about to be conveyed to the current belt paper feeding mechanism 1, the straightening drive motor 5 starts to drive the cam 6 to rotate, realizing synchronous action, thereby forming a push-and-pull cycle working state, thereby ensuring that each corrugated paper can be conveyed in a straight posture.

[0061] At the same time, since the adjusting screw 4 is connected to the adjusting drive motor 3 through an axially movable follower connection structure, if the belt paper feeding mechanism 1 moves laterally, it will pull the adjusting screw 4 to move synchronously, and the follower connection structure will provide lateral movement compensation, which can not only make the straightening work proceed smoothly, but also will not affect the distance adjustment, which is very clever.

[0062] When adjusting the distance, the adjusting drive motor 3 is used to drive the adjusting screw 4 to rotate, thereby adjusting the distance between the belt paper feeding mechanism 1 and the suction paper feeding mechanism 2; wherein, since the screw assembly is also connected to the bottom of the belt paper feeding mechanism 1, that is, the belt paper feeding mechanism 1 is connected to two sets of different screws; then when the adjusting screw 4 is rotated, the straightening screw 10 will be driven to rotate through the linkage structure, and since the rotation direction of the straightening screw 10 is opposite to that of the adjusting screw 4, it will rotate in the opposite direction to avoid the belt paper feeding mechanism 1, so that the belt paper feeding mechanism 1 can move along the straightening screw 10, ensuring that the distance adjustment work is completed smoothly.

[0063] Example 2

[0064] See also Figure 7 , which is different from the first embodiment, the straightening drive motor 5 of the present embodiment is composed of an adjusting drive motor 3; the straightening power mechanism also includes a lifting drive mechanism, which includes a lifting plate 20 and a lifting drive cylinder 21, the adjusting drive motor 3 is arranged on the lifting plate 20, the cylinder body of the lifting drive cylinder 21 is fixed on the frame of the air suction and paper feeding mechanism 2, and the telescopic rod of the lifting drive cylinder 21 is fixedly connected to the lifting plate 20. Through the above structure, under the drive of the lifting drive cylinder 21, the working mode is switched, so that the active bevel gear 11 is meshed with the driven bevel gear 12, or the cam 6 is moved to the front of the straightening transmission plate 7, so that one motor can be shared, which is conducive to simplifying the structure and reducing costs.

[0065] The above is a preferred embodiment of the present invention, but the embodiment of the present invention is not limited to the above content. Any other changes, modifications, substitutions, combinations, and simplifications made without departing from the spirit and principles of the present invention should be equivalent replacement methods and are included in the protection scope of the present invention.
