Description

Technical Field

[0001] The utility model relates to the technical field of glue dipping equipment, in particular to a transmission mechanism for dipping paper into glue. Background Art

[0002] In the modern furniture manufacturing and decoration industry, impregnated paper is an important surface decoration material and is widely used in the surface decoration of cabinets, wardrobes, floors and other products. The production process of impregnated paper involves several key steps, among which dipping is a crucial link. The dipping production line usually adopts advanced technology and equipment to evenly coat the adhesive such as amino resin on the surface of solid color base paper or printed decorative paper to form a solid adhesive film, thereby improving its physical properties and aesthetics.

[0003] The gluing production line usually includes multiple processes such as raw material preparation, gluing, drying, cooling, cutting, etc. During the gluing process, the paper passes through the gluing tank and is fully in contact with the adhesive, and then is quickly dried in the drying equipment to form a uniform adhesive film. In this process, the paper transmission speed and the amount of adhesive applied have an important impact on the product quality. Therefore, the transmission mechanism of the gluing production line must accurately control the paper transmission speed and position to ensure uniform coating of the adhesive.

[0004] Deficiencies of existing technology:

[0005] During the gluing process, a thicker adhesive is coated on the surface of the paper. These adhesives have a certain fluidity before drying. When the paper moves on the transmission mechanism, it is affected by vibration or tension changes, and the surface adhesive is easy to drip or flow to the sides of the conveyor roller, forming glue stains that are difficult to clean. In addition, the dripping adhesive will also contaminate the floor of the production workshop, increasing the difficulty and cost of cleaning. Utility Model Content

[0037] See also Figure 1-5 As shown, the utility model provides a technical solution of a transmission mechanism for impregnating paper with glue: a transmission mechanism for impregnating paper with glue, comprising a frame 1, and a glue basin 2 installed at the bottom of the frame 1, a feeding transmission roller 3 and a discharging transmission roller 4 are fixed on the side walls of the frame 1, a plurality of positioning rollers 5 are installed inside the glue basin 2, and a dipping scraping structure 6 is arranged on the side of the discharging transmission roller 4;

[0038] The glue scraping structure 6 includes a fixed plate 601, a locking mechanism 605, a scraping sleeve 606, and a drainage mechanism 609. The fixed plate 601 is fixedly connected to the two side walls of the frame 1. A movable hole 602 is opened inside the fixed plate 601. The first scraping roller 603 and the second scraping roller 604 are respectively installed inside the movable hole 602. The locking mechanism 605 is arranged at both ends of the first scraping roller 603 and the second scraping roller 604. The locking mechanism 605 is used to lock the first scraping roller 603 and the second scraping roller The relative position and state of the scraping roller 604, the scraping sleeve 606 is arranged on the outer side wall of the first scraping roller 603 and the second scraping roller 604, the scraping sleeve 606 includes an annular portion 607 and an extension portion 608 extending outward from the annular portion 607, the extension portion 608 is arc-shaped, and its thickness gradually increases at one end close to the annular portion 607, the drainage mechanism 609 is arranged at both ends of the scraping sleeve 606, the drainage mechanism 609 is used to guide the scraped adhesive to flow back into the glue basin 2, and during the dipping process. During the impregnation, the impregnated paper passes through the feed conveying roller 3 from the raw material conveying section into the glue basin 2, and is conveyed to the drying equipment by the discharge conveying roller 4 for drying after the impregnation. In this process, in order to prevent the excess adhesive from dripping and affecting the environment and reduce the outflow of the adhesive, the impregnation scraping structure 6 is designed. When the impregnated paper passes through the first scraping roller 603 and the second scraping roller 604, the excess adhesive on its surface will be scraped off by the scraping sleeve 606 on the surface of the roller body, and the scraped adhesive will be drained at both ends. Under the guidance of the mechanism 609, it flows into the glue basin 2 again and is recycled. In this design, the arc design of the extension part 608 can keep the contact surface with the impregnated paper smooth after adjusting it at multiple angles to avoid damaging the impregnated paper. The thickened design at the connection between the annular part 607 and the extension part 608 can improve the supporting force of the extension part 608. In addition, the closer to the connection between the annular part 607 and the extension part 608, the higher the clamping force that can be achieved, which is convenient for scraping off the residual material of different impregnated papers.

[0039] The drainage mechanism 609 includes a guide part 6091 and a guide rope 6092. The guide part 6091 is arranged at both ends of the scraper sleeve 606. The guide rope 6092 is fixedly connected to the bottom of the guide part 6091. The other end of the guide rope 6092 is fixedly connected to the inner wall of the glue basin 2. During the guiding and reflux process of the adhesive, the scraped adhesive will flow along the bottom of the scraper sleeve 606, and then be concentrated to the tip part under the guidance of the guide part 6091, and finally flow back to the glue basin 2 under the guidance of the guide rope 6092.

[0040] The scraper sleeve 606 is made of rubber. By designing the scraper sleeve 606 to be made of rubber, the scraper sleeve 606 can fit closely to the surface of the impregnated paper, thereby accurately scraping off excess adhesive. In addition, rubber has excellent flexibility and elasticity, which can avoid damaging the impregnated paper during the scraping process.

[0041] The locking mechanism 605 includes a first threaded portion 6051 and a second threaded portion 6053. The first threaded portion 6051 is arranged at both ends of the first scraping roller 603 and the second scraping roller 604. An inner clamping ring 6052 is arranged on the first threaded portion 6051. The second threaded portion 6053 is arranged at both ends of the first scraping roller 603 and the second scraping roller 604 and is located on the outside of the first threaded portion 6051. An outer clamping ring 6054 is arranged on the second threaded portion 6053. During the adjustment process of the first scraping roller 603 and the second scraping roller 604, it is necessary to unlock the inner clamping ring 6052 and the outer clamping ring 6054 first. At this time, the two scraping rollers can be adjusted in position and angle. After the adjustment is completed, the two clamping rings can be clamped to fix the plate 601.

[0042] A rubber interlayer 7 is provided on the side of the inner clamping ring 6052. This design can significantly enhance the friction between the clamping ring and the fixing plate 601, which helps to maintain the stability of the scraper roller during the operation of the equipment and prevent it from accidentally sliding or unlocking.

[0043] The length of the movable hole 602 is 1.5 times greater than the center distance between the first scraping roller 603 and the second scraping roller 604. This design can ensure that there is enough movable space between the first scraping roller 603 and the second scraping roller 604 for adjustment to meet different work requirements.

[0044] The working principle of the utility model is as follows:

[0045] In the transmission process of the transmission mechanism for impregnated paper of the present embodiment, the scraping sleeve 606 on the surface of the first scraping roller 603 and the second scraping roller 604 will scrape off excess adhesive. Since the scraping sleeve 606 is made of rubber, its excellent flexibility and elasticity ensure that the scraping process will not damage the impregnated paper, and the scraped adhesive will flow along the bottom of the scraping sleeve 606 and then gather at the tip of the guide part 6091. The guide rope 6092 connects the guide part 6091 with the inner wall of the glue basin 2 to form a guiding path, so that the scraped adhesive can smoothly flow back to the glue basin 2, preventing the adhesive from dripping during the transmission process and affecting the environment, while also realizing the recycling of the adhesive.
