Description

Technical Field

[0001] This utility model relates to the field of corrugated paper processing technology, and in particular to a device for uniformly coating corrugated base paper with glue. Background Technology

[0002] Corrugated paper, with its good cushioning and cost advantages, has become a widely used packaging material. It is made of flat facing paper and corrugated paper with a wave-like structure bonded together. As the core raw material for producing corrugated paperboard, the corrugated base paper must be glued together with the help of a glue coating device in the production process to achieve a firm bond between the multiple layers of paper. This requires the glue to be applied evenly and precisely to the surface of the corrugated base paper to fundamentally ensure the bonding quality and overall physical properties of the corrugated paper.

[0003] The corrugated base paper gluing uniform device consists of four main modules: glue supply, gluing execution, base paper conveying, and control. Glue is stored in a glue tank and precisely delivered to the gluing roller by a glue pump. The roller rotates, picks up the glue, and transfers it onto the base paper, while a doctor blade simultaneously removes excess glue. The base paper moves forward at a uniform speed on the conveyor belt to ensure comprehensive gluing. Meanwhile, the control system adjusts parameters such as the glue pump flow rate and the gluing roller speed based on the base paper thickness and material, ensuring uniform gluing from all angles.

[0004] Currently, corrugated base paper coating uniform devices have significantly improved the coating quality of corrugated base paper and promoted the development of the industry. However, in actual production, some coating devices still have shortcomings. During coating, the base paper is subjected to uneven force in the conveying and coating process. Due to the unbalanced pressure distribution of the coating roller and the unstable operation of the conveyor belt, the base paper will have wrinkles, warping and other unevenness. These problems not only affect the coating uniformity, but also reduce the quality of corrugated board and limit the full play of the advantages of the coating device. Therefore, a corrugated base paper coating uniform device is proposed to solve the above problems. Utility Model Content

[0023] 1. In this utility model, when the motor starts running, its output shaft drives the support rod to swing. During the swinging process, the pull rod closely connected to it is driven to swing. The swinging of the pull rod further pushes the connecting rod, causing the connecting rod to move up and down reciprocally. The pressure plate installed at the bottom of the connecting rod then continuously squeezes the raw paper material towards the glue leveling table according to the preset rhythm, thereby effectively improving the unevenness of the paper.

The profile curve of the cam changes continuously, and it continuously applies a periodic force to the push rod. With the cooperation of the push rod and the spring, the push rod performs regular reciprocating motion. In this process, the push rod pushes the raw paper material on the storage plate, allowing it to enter the next position in an orderly manner, so as to achieve efficient and stable automatic material discharge.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figures 1 to 3 This utility model provides an embodiment of a corrugated base paper adhesive uniform coating device, including an adhesive leveling table 1. A conveyor belt is installed inside the adhesive leveling table 1. A support block 2 is fixedly connected to one side of the top of the adhesive leveling table 1. A motor 3 is fixedly connected to one side of the support block 2, serving as one of the main power sources. A rotating column 4 is fixedly connected to the drive end of the motor 3. A support rod 6 is fixedly connected to the other side of the rotating column 4, allowing the driving force of the motor 3 to be transmitted. A pull rod 7 is rotatably connected to the side of the support rod 6 away from the rotating column 4, allowing the motor... The driving force of 3 is transmitted again, and the other side of the pull rod 7 is movably connected to the connecting rod 8. The bottom of the connecting rod 8 is fixedly connected to the pressure plate 9, so that the pressure plate 9 can squeeze and fix the raw paper material during operation. The outer wall of the rotating column 4 is fixedly connected to the glue-equalizing column 5, so that the glue-equalizing column 5 can rotate evenly. The side of the glue-equalizing table 1 is fixedly connected to the feeding table 10, so that the raw paper material can enter the glue-equalizing table 1 through the feeding table 10. The other side of the feeding table 10 is fixedly connected to the feeding component, and the inside of the feeding component is fixedly connected to the pushing component.

[0033] Reference Figures 1 to 3The feeding assembly includes two bases 11, which support the entire assembly. The two bases 11 are fixedly connected to both sides of the feeding platform 10, making the entire device more stable. One side of one base 11 is fixedly connected to a motor 12, which serves as one of the main driving forces. The driving end of the motor 12 is fixedly connected to a rotating column 13, and the other side of the rotating column 13 is fixedly connected to a drive wheel 15, which allows the driving force of the motor 12 to be transmitted. A connecting plate 16 is fixedly connected to the adjacent side of the two bases 11. Two rotating plates 17 are rotatably connected to one side of the connecting plate 16, so that the rotating plates 17 have support points when rotating. A connecting column 18 is rotatably connected to the adjacent side of the two rotating plates 17. A roller 19 is fixedly connected to the outer wall of the connecting column 18. The roller 19 contacts the cam 14, so that the cam 14 will have a distance difference with the roller 19 when rotating.

[0034] Reference Figures 2 to 4 The feeding assembly includes a cam 14, the inner wall of which is fixedly connected to the outer wall of the rotating column 13, so that the cam 14 moves in a circular motion synchronously with the rotating column 13. A storage plate 24 is fixedly connected to one side of each of the two adjacent bases 11, allowing the raw paper material to be placed on the storage plate 24. A base 25 is fixedly connected to the bottom of the storage plate 24, and a limit post 26 is fixedly connected inside the base 25. A push rod 28 is slidably connected to the outer wall of the limit post 26, allowing the push rod 28 to move horizontally. A spring 27 is sleeved on the outer wall of the limit post 26. The two sides of the push rod 28 are respectively fixedly connected to one side of each of the two rotating plates 17, allowing the push rod 28 to be received by the rotating plates. The force of 17 is used for movement. One side of spring 27 is in contact with one side of base 25, and the other side of spring 27 is in contact with one side of push rod 28. This allows push rod 28 to return to its original position by the elastic deformation of spring 27 when no force is applied, thus achieving reciprocating motion. Both base 25 and storage plate 24 have through holes. Push rod 28 slides in the through holes, allowing push rod 28 to touch and push the raw paper material. Support block 23 is fixedly connected to one side of the top of the glue leveling table 1. One side of rotating column 1 4 is in contact with the inside of support block 23. The side of connecting rod 8 away from pull rod 7 slides on the side of support block 23, making the whole device more stable.

[0035] Reference Figure 1 A driven wheel 21 is fixedly connected to one side of another base 11, and a driving wheel 15 is fixedly connected to one side of another base 11. The driving wheel 15 and the driven wheel 21 are coupled together by a belt 20, so that the driving force received by the driving wheel 15 can be transmitted. Two rollers 22 are rotatably connected to adjacent sides of the two bases 11. One side of one roller 22 is fixedly connected to one side of the driven wheel 21, so that one roller 22 can rotate with the rotation of the driven wheel 21.

[0036] Working principle: When it is necessary to apply glue to the corrugated base paper, the base paper material is placed in the storage plate 24, and the motor 12 is turned on. The driving force of the motor 12 causes the rotating column 13 to drive the drive wheel 15 and the cam 14 to rotate. Since the pressure plate 9 is in contact with the cam 14, and the cam 14 is convex, the rotating plate 17 drives the push rod 28 to slide inside the base 25 and at the bottom of the storage plate 24, so that the base paper material is pushed away from the bottom of the storage plate 24. Due to the rotation of the drive wheel 15, the driven wheel 21 drives a roller 22 to rotate. When the push rod 28 pushes the raw paper material between the two rollers 22, it will be pushed to the feeding table 10 and enter the glue leveling table 1 by the rotation of one of the rollers 22, and the uneven raw paper material can be flattened. After the raw paper material enters the glue leveling table 1, it will be transported by its built-in conveyor belt. The motor 3 is turned on, so that the driving force of the motor 3 drives the support rod 6 to drive the pull rod 7, so that the connecting rod 8 can perform up and down reciprocating motion, so that the pressing plate 9 can press the raw paper material downward towards the glue leveling table 1. The raw paper material is glued evenly by the action of the glue leveling column 5.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
