Abstract
Description
Technical Field
[0001] This utility model relates to the field of corrugated cardboard lamination technology, and more specifically, to a high-speed corrugated cardboard composite lamination device. Background Technology
[0002] Corrugated cardboard is a type of sheet material made of multiple layers of paper, commonly used for packaging and transportation. Its structure typically consists of a corrugated core sandwiched between two layers of flat paper (face paper). This design gives corrugated cardboard good strength and pressure resistance. Corrugated cardboard laminating equipment is used to bond different types of paper or cardboard together into composite materials using adhesives and pressure. This equipment plays a crucial role in the production of corrugated cardboard.
[0003] Corrugated cardboard laminating equipment is divided into flat plate laminating equipment and roller laminating equipment. Flat plate laminating equipment usually consists of two pressure plates, which laminate the paper by pressure. It can be operated manually or semi-automatically and is suitable for small-scale production or sample making. Roller laminating equipment consists of a set of rollers arranged vertically or laterally. The paper is laminated by the pressure of the rollers. It is mostly fully automatic and suitable for large-scale production lines. Due to its continuous feeding and laminating characteristics, it can achieve high-efficiency production.
[0004] Existing high-speed corrugated cardboard laminating equipment, such as roller presses, while capable of continuous feeding and laminating for high-efficiency production, suffers from several drawbacks. First, glue is applied to the surface of the paper or cardboard before laminating. During lamination, the glue easily overflows from the edges of the cardboard and sticks to the surface of the laminating rollers, hindering the lamination process. Even with scraping devices such as scrapers, glue tends to accumulate on the scraper during continuous scraping, causing it to flow everywhere, affecting the lamination process and polluting the working environment. Therefore, to solve the above technical problems, this application proposes a high-speed corrugated cardboard laminating equipment. Utility Model Content
[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a high-speed corrugated cardboard laminating and pressing equipment to solve the technical problem of poor glue scraping function of the existing high-speed corrugated cardboard laminating and pressing equipment.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-speed corrugated cardboard composite pressing device, comprising...
[0007] A frame, wherein a first pressing roller and a second pressing roller are rotatably mounted on the inner side wall of the frame;
[0008] The first elastic scraping component is installed on the inner side wall of the frame and the scraping end abuts against the outside of the first pressing roller;
[0009] The second elastic scraper assembly is installed on the inner side wall of the frame and the scraper end abuts against the outside of the second pressing roller. The structure of the second elastic scraper assembly is the same as that of the first elastic scraper assembly, both of which include a glue storage tank. The glue storage tank is V-shaped and the opening faces upward.
[0010] A glue extraction box is installed on the outer wall of the frame. The glue extraction box includes a sealed box. The glue inlet inside the sealed box is connected to a glue storage tank through a hose. A piston plate is slidably connected to the inner side wall of the sealed box. A one-way air outlet valve is installed on the piston plate.
[0011] The drive assembly is located on the outer wall of the frame and can drive the first pressing roller, the second pressing roller and the piston plate to move.
[0012] Furthermore, the second elastic glue scraping assembly also includes a fixed frame that is fixedly installed on the inner side wall of the frame, a guide rod that is slidably connected to the fixed frame, and a glue storage tank that is fixed to the end of the guide rod.
[0013] Furthermore, the guide rod is fitted with a spring, and a flexible scraper strip is installed on the outer wall of the glue storage tank.
[0014] Furthermore, the drive assembly includes a first gear fixed to the end of the first pressing roller, the power input end of the first gear is connected to an electric motor, the first gear is externally meshed with a second gear, and the second gear is fixed to the end of the second pressing roller.
[0015] Furthermore, the outer wall of the second gear is rotatably connected to a connecting rod via a rotating assembly, and the bottom end of the connecting rod is hinged to the top of the piston plate via a hinge assembly.
[0016] Compared with the prior art, the present invention has the following beneficial effects:
[0017] The high-speed corrugated cardboard laminating equipment disclosed in this utility model can continuously scrape the glue off the rollers during the operation of the pressing rollers through the first elastic scraping component and the second elastic scraping component.

[0027] like Figure 1-4 As shown, this utility model provides a high-speed corrugated cardboard composite pressing equipment, including a frame 1, with a first pressing roller 2 and a second pressing roller 3 rotatably mounted on the inner side wall of the frame 1;
[0028] The first elastic scraping component 4 is installed on the inner side wall of the frame 1 and the scraping end abuts against the outside of the first pressing roller 2;
[0029] The second elastic scraping component 5 is installed on the inner wall of the frame 1 and the scraping end abuts against the outside of the second pressing roller 3. The structure of the second elastic scraping component 5 is the same as that of the first elastic scraping component 4. Both include a glue storage tank 504, which is V-shaped and has an upward opening. The second elastic scraping component 5 also includes a fixed frame 501 fixedly installed on the inner wall of the frame 1. A guide rod 502 is slidably connected to the fixed frame 501. The glue storage tank 504 is fixed at the end of the guide rod 502. A spring 503 is sleeved on the guide rod 502. A flexible scraping strip 505 is installed on the outer wall of the glue storage tank 504. The guide rod 502 and the spring 503 cooperate with the glue storage tank 504 and the flexible scraping strip 505 to give the flexible scraping strip 505 a certain elastic displacement space along the sliding direction of the guide rod 502. This facilitates scraping while preventing rigid collision with the pressing roller and damage to the pressing roller.
[0030] The glue extraction box 7 is installed on the outer wall of the frame 1. The glue extraction box 7 includes a sealed box 701. The glue inlet inside the sealed box 701 is connected to the glue storage tank 504 through a hose 8. A piston plate 702 is slidably connected to the inner wall of the sealed box 701. A one-way air valve 703 is installed on the piston plate 702. When the piston plate 702 moves downward in the sealed box 701, the air in the sealed box 701 is discharged from the one-way air valve 703. When the piston plate 702 moves upward in the sealed box 701, the one-way air valve 703 is in a blocked state, so that the sealed box 701 is in a negative pressure state. The viscous glue is drawn from the glue storage tank 504 into the sealed box 701 through two hoses 8.
[0031] The drive assembly 6 is located on the outer wall of the frame 1 and can drive the first pressing roller 2, the second pressing roller 3 and the piston plate 702 to move. The high-speed corrugated cardboard composite pressing equipment disclosed in this utility model can continuously scrape the glue on the rollers when the pressing rollers are working through the first elastic glue scraping assembly 4 and the second elastic glue scraping assembly 5. When the drive assembly 6 drives the pressing rollers to work continuously, it can simultaneously drive the piston plate 702 to mechanically move up and down in the sealed box 701. With the cooperation of the one-way air valve 703, the glue in the glue storage tank 504 is continuously extracted during the glue scraping operation, and the glue spillage prevention effect is excellent.
[0032] Furthermore, the drive assembly 6 includes a first gear 601 fixed to the end of the first pressing roller 2. The power input end of the first gear 601 is connected to a motor 603. The first gear 601 is externally meshed with a second gear 602. The second gear 602 is fixed to the end of the second pressing roller 3. The outer wall of the second gear 602 is rotatably connected to a connecting rod 605 through a rotating assembly 604. The bottom end of the connecting rod 605 is hinged to the top of the piston plate 702 through a hinge assembly 606 to facilitate synchronous drive. While the motor 603 drives the first gear 601 and the first pressing roller 2 to rotate at high speed, the second gear 602 and the second pressing roller 3 also rotate synchronously in the opposite direction at high speed because the first gear 601 is externally meshed with the second gear 602. When the second gear 602 rotates, it drives the connecting rod 605 to drive the piston plate 702 to reciprocate up and down, drawing out the viscous glue in the glue storage tank 504.
[0033] Working Principle: The high-speed corrugated cardboard laminating equipment disclosed in this utility model continuously scrapes the glue off the rollers during the operation of the pressing rollers through the first elastic scraping component 4 and the second elastic scraping component 5. Powered by an external power supply, the motor 603 is turned on via an external switch. The motor 603 drives the first gear 601 and the first pressing roller 2 to rotate at high speed. Simultaneously, since the first gear 601 is externally meshed with the second gear 602, the second gear 602 and the second pressing roller 3 also rotate synchronously in opposite directions at high speed. Through the cooperation of the first pressing roller 2 and the second pressing roller 3, the corrugated cardboard is pressed together. At the same time, the flexible scraping strips 505 of the first elastic scraping component 4 and the second elastic scraping component 5 respectively abut against the first pressing roller 2 and the second pressing roller 3, scraping the glue off. The scraped glue flows into the corresponding "V"-shaped glue storage tank 504 with its opening facing upwards under its own gravity, initially storing the glue. The guide rod 502 and spring 50... 3. The adhesive storage tank 504 and the flexible adhesive scraper 505 work together to provide the flexible adhesive scraper 505 with a certain elastic displacement space along the sliding direction of the guide rod 502. This facilitates adhesive scraping while preventing rigid collisions with the pressing roller that could damage it. Furthermore, when the driving assembly 6 drives the pressing roller to work continuously, it can simultaneously drive the piston plate 702 to mechanically move up and down within the sealed box 701. Combined with the one-way vent valve 703, this continuously draws adhesive from the storage tank 504 during the adhesive scraping process. When the piston plate 702 moves downward within the sealed box 701, the air inside the sealed box 701 is discharged through the one-way vent valve 703. When the piston plate 702 moves upward within the sealed box 701, the one-way vent valve 703 is in a blocked state, creating a negative pressure state inside the sealed box 701. The viscous glue is then drawn from the glue storage tank 504 into the sealed box 701 through two hoses 8, resulting in excellent glue spillage prevention (the motor 603 is a commercially available product and is connected to an external switch and external power supply).
