Description

TECHNICAL FIELD

[0001] The utility model relates to corrugated board flatness processing equipment technical field especially relates to a kind of mechanical mechanism for adjusting the flatness of corrugated board. BACKGROUND

[0002] In the production preparation process of corrugated board, internal moisture distribution is uneven and production heat is unstable, which will seriously affect the flatness of corrugated board. Once the flatness of corrugated board is poor, the quality of subsequent processes such as paper feeding, printing and spraying cannot be guaranteed.

[0003] Currently, the methods to improve the flatness of corrugated board mainly include the following: first, stacking and pressing. The paperboard is stacked and pressed alternately by artificial water spraying, and then left for a period of time. Second, contact the paperboard supplier to adjust the production process. Third, distinguish between curved paperboard and flat paperboard, pick out the curved paperboard, and complete the production in two times by reducing the speed.

[0004] However, these methods have certain disadvantages. The artificial water spraying operation of stacking and pressing not only consumes manpower, but also requires higher experience of the operator. The alternately stacking and long time standing greatly increases the time cost. The adjustment of the paperboard supplier requires high communication and coordination cost, and the adjustment of the supplier may take a certain period of time and delay the production progress. As for the method of picking out the curved paperboard and feeding in two times, reducing the speed will slow down the overall production efficiency and increase the manual sorting work of paperboard, which also increases the time cost and labor cost.

[0005] Although the existing methods to improve the flatness of corrugated board can solve the problem to some extent, they significantly increase the time cost and labor cost, and it is urgent to explore more efficient and low-cost solutions to ensure the smooth production and subsequent processing of corrugated board. UTILITY MODEL CONTENTS

[0006] Therefore, the utility model wants to solve the technical problem: how to provide a mechanical mechanism for adjusting the flatness of corrugated board to uniformly coat water on the surface of corrugated board and improve the overall flatness of corrugated board.

[0007] To achieve the above purpose, the utility model provides a mechanical mechanism for adjusting the flatness of corrugated board, which comprises a paper feeding unit and a water coating unit. The paper feeding unit mainly comprises a rack, a paper feeding workbench and a paper separator. The water coating unit mainly comprises a paper feeding roller, a water scraping roller, a water feeding roller, a first adjusting mechanism, a second adjusting mechanism and a water tank.

[0008] The paper feeding roller, the water scraping roller and the water feeding roller are connected to the frame, and the paper feeding roller and the water feeding roller are rotatably connected to the frame, and the water scraping roller is fixedly connected to the frame.

[0009] The paper feeding roller and the water feeding roller are vertically spaced apart, and the paper feeding roller is located above the water feeding roller.

[0010] The water scraping roller and the water feeding roller are horizontally spaced apart, and the outer wall of the water scraping roller is in contact with or spaced apart from the outer wall of the water feeding roller, and the water scraping roller scrapes the excess water on the outer wall of the water feeding roller in rotation.

[0011] The water tank is used for containing water, and the water feeding roller is at least partially contained in the water tank, and the outer wall of the water feeding roller is in contact with the water contained in the water tank.

[0012] The water feeding roller coats part of the water in the water tank on the surface of the corrugated paper between the water feeding roller and the paper feeding roller in rotation, and the outer wall of the water feeding roller is in contact with or spaced apart from the water scraping roller in rotation, and the water scraping roller scrapes the excess water on the outer wall of the water feeding roller.

[0013] The first adjusting mechanism is connected to the paper feeding roller, and is used for adjusting the gap size of the paper feeding roller and the water feeding roller in the vertical direction, and the second adjusting mechanism is connected to the water scraping roller, and is used for adjusting the gap size of the water scraping roller and the water feeding roller in the horizontal direction.

[0014] Further, the paper feeding workbench supports the corrugated paper, and the water scraping roller is located between the paper feeding workbench and the water feeding roller.

[0015] Further, the first adjusting mechanism and the second adjusting mechanism are connecting shafts, and the first adjusting mechanism and the second adjusting mechanism are respectively connected to the shaft center of the paper feeding roller and the shaft center of the water scraping roller.

[0016] Further, the outer diameter of the water feeding roller is larger than the outer diameter of the water scraping roller.

[0017] Further, the rear end of the paper feeding workbench is provided with a supporting mechanism, and the supporting mechanism supports the bottom of the corrugated paper.

[0018] Further, the paper separator is arranged on the paper feeding table and close to the paper feeding roller, and is used for limiting the number of paper sheets at the gap between the paper feeding table and the paper feeding roller.

[0019] Compared with the related art, the mechanical mechanism for adjusting flatness of corrugated paper has the advantages that:

[0020] The water feeding roller is at least partially immersed in the water tank, and the outer wall of the water feeding roller carries water in the water tank during rotation. When the corrugated paper moves forward between the gap between the paper feeding roller and the water feeding roller and is driven by the paper feeding roller and the water feeding roller, the water feeding roller can uniformly coat the water carried on the corrugated paper, and the water feeding roller continuously rotates, and each part of the water feeding roller in contact with the corrugated paper can in turn transfer the water to the corrugated paper, thereby realizing more uniform water coating operation.

[0021] The water scraping roller and the water feeding roller are arranged in the horizontal direction, and the water scraping roller can scrape off the excess water on the outer wall of the water feeding roller.

BRIEF DESCRIPTION OF DRAWINGS

[0023] Figure 1 The figure is a structural schematic view of the mechanical mechanism for adjusting flatness of corrugated paper in the embodiments of the present application. DETAILED DESCRIPTION

[0024] The present application will be further described in detail below in combination with the drawings and specific embodiments.

[0025] Please see Figure 1 As shown in the figure, the present application provides a mechanical mechanism for adjusting flatness of corrugated paper, and the paper feeding unit mainly includes a rack 11, a paper feeding table 12 and a paper separator 13, and the water coating unit mainly includes a paper feeding roller 21, a water scraping roller 22, a water feeding roller 23, a first adjusting mechanism 31, a second adjusting mechanism 32 and a water tank 15.

[0026] The paper feeding roller 21, the water wiping roller 22 and the water feeding roller 23 are connected to the frame 11, the paper feeding roller 21 and the water feeding roller 23 are rotatably connected to the frame 11, and the water wiping roller 22 is fixedly connected to the frame 11.

[0027] The paper feeding roller 21 and the water feeding roller 23 are arranged in a vertical direction with a gap A between them, and the paper feeding roller 21 is arranged above the water feeding roller 23. The corrugated board 1 moves forward through the gap A between the paper feeding roller 21 and the water feeding roller 23 under the joint clamping and driving of the paper feeding roller 21 and the water feeding roller 23.

[0028] The corrugated board is supported on the paper feeding table 12, and the water wiping roller 22 is arranged between the paper feeding table 12 and the water feeding roller 23. The rear end of the paper feeding table 12 is provided with a supporting mechanism 14 which supports the bottom of the corrugated board.

[0029] The paper separator 13 is arranged on the paper feeding table 12 and close to the paper feeding roller 21. The paper separator 13 is used to limit the number of paper sheets moving towards the gap between the paper feeding roller 21 and the water feeding roller 23 from the paper feeding table 12. The paper separator 13 can effectively avoid the situation that multiple paper sheets enter the gap between the rollers at the same time, and ensure that only a single paper sheet or a specified number of paper sheets are fed at a time. Specifically, a driving component such as a hand wheel or a motor is arranged on the top of the paper separator 13 to drive the baffle to move in a vertical direction. The number of paper sheets to be fed is limited by adjusting the distance between the bottom of the baffle and the table top of the paper feeding table 12.

[0030] The frame 11 serves as the support body of the entire mechanism and provides a stable mounting basis for the paper feeding roller 21, the water wiping roller 22, the water feeding roller 23 and other components. The paper feeding table 12 is arranged horizontally on the frame 11 and mainly serves to support and feed the corrugated board, ensuring the stability of the corrugated board during the feeding process. The supporting mechanism 14 is arranged at the rear end of the paper feeding table 12 and supports the bottom of the corrugated board, further reducing the shaking and unnecessary friction of the corrugated board during the feeding process, so that the corrugated board can smoothly pass through the gap between the paper feeding roller 21 and the water feeding roller 23.

[0031] The water wiping roller 22 and the water feeding roller 23 are arranged in a horizontal direction with a gap between them, and the outer wall surface of the water wiping roller 22 is in contact with or spaced apart from the outer wall of the water feeding roller.

[0032] The water tank 15 is used to contain water, and the water feeding roller 23 is at least partially contained in the water tank 15, and the outer wall of the water feeding roller 23 is in contact with the water contained in the water tank 15.

[0033] The water feeding roller 23 is in contact with or spaced from the water scraping roller 22 during rotation, and the water scraping roller 22 scrapes the excess water on the outer wall of the water feeding roller 23. The outer diameter of the water feeding roller 23 is larger than that of the water scraping roller 22.

[0034] The water feeding roller 23 and the water scraping roller 22 are installed on the frame 11 through rotating connection, and are flexible in rotation. The water scraping roller 22 is fixedly installed on the frame 11. The water feeding roller 23 is located above the water scraping roller 22, and the two are spaced in the vertical direction.

[0035] When the water feeding roller 23 is driven to rotate, the corrugated paper is driven to move forward by the friction between the water feeding roller 23 and the corrugated paper, and the water feeding roller 23 is also driven to rotate. The water feeding roller 23 is at least partially immersed in the water tank 15, and the water tank 15 contains sufficient water. During rotation of the water feeding roller 23, the outer wall of the water feeding roller 23 adheres to the water in the water tank 15, and uniformly coats the water on the surface of the corrugated paper passing through the gap between the water feeding roller 23 and the water scraping roller 22.

[0036] Since the water feeding roller 23 continuously rotates, each part in contact with the corrugated paper sequentially transfers water to the corrugated paper, achieving relatively uniform water coating and laying a foundation for subsequent improvement of the flatness of the corrugated paper.

[0037] The water scraping roller 22 and the water feeding roller 23 are spaced in the horizontal direction, and the outer wall surface of the water scraping roller 22 and the outer wall of the water feeding roller 23 can be adjusted to be in contact or spaced according to actual needs. When the water on the surface of the water feeding roller 23 is excessive, the water scraping roller 22 can scrape off the excess water.

[0038] During rotation of the water feeding roller 23, the water scraping roller 22 uniformly scrapes the water on the surface of the water feeding roller 23, ensuring that the water feeding roller 23 is always in contact with the corrugated paper with an appropriate amount of water, avoiding excessive water coating on the corrugated paper due to excessive water on the water feeding roller 23, and further ensuring the stability and uniformity of water coating of the water feeding roller 23, thereby improving the consistency of the flatness of the corrugated paper.

[0039] The first adjusting mechanism 31 is connected to the water feeding roller 23, and is used to adjust the gap size of the water feeding roller 23 and the water scraping roller 23 in the vertical direction. The second adjusting mechanism 32 is connected to the water scraping roller 22, and is used to adjust the gap size of the water scraping roller 22 and the water feeding roller 23 in the horizontal direction.

[0040] The first adjusting mechanism 31 and the second adjusting mechanism 32 are connecting shafts, and the first adjusting mechanism 31 and the second adjusting mechanism 32 are connected to the shafts of the paper feeding roller 21 and the water scraping roller 22 respectively.

[0041] The first adjusting mechanism 31 is connected to the paper feeding roller 21, and the second adjusting mechanism 32 is connected to the water scraping roller 22.

[0042] Similarly, the second adjusting mechanism 32 is connected to the shaft of the water scraping roller 22, and by adjusting the position of the second adjusting mechanism 32 on the rack 11, the gap size between the water scraping roller 22 and the water feeding roller 23 in the horizontal direction can be adjusted.

[0043] In addition, the outer diameter of the water feeding roller 23 is larger than that of the water scraping roller 22.

[0044] Finally, it should be noted that the above examples are only used to illustrate the technical solutions of the present application, and are not limited thereto; although the present application has been described in detail with reference to the foregoing examples, those skilled in the art should understand that the technical solutions described in the foregoing examples can still be modified, or some technical features can be replaced by equivalents; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application.
