Description

Technical Field

[0001] This utility model relates to the field of base fabric sizing technology, and in particular to a base fabric sizing device for a coating and bonding machine. Background Technology

[0002] A coating and laminating machine is a device used for coating and laminating materials. It can evenly coat adhesives, coatings, and other substances onto base fabrics and other materials, and can tightly bond multiple layers of materials together. It is widely used in packaging, electronics, and textile industries. The core component of a coating and laminating machine is the sizing device, which plays a crucial role in evenly applying a specific sizing agent to the base fabric. This device mainly consists of a sizing tank, a sizing roller, a pressure roller, and a guide roller. The sizing tank serves as a storage container for the sizing agent, providing raw materials for the entire sizing process. The sizing roller is partially immersed in the sizing tank, adsorbing the sizing agent through its surface properties, and then transferring it to the base fabric upon contact. The pressure roller works in conjunction, precisely controlling the amount of sizing agent absorbed by the base fabric by adjusting the pressure, ensuring a uniform sizing layer. The guide roller guides the base fabric smoothly, ensuring the sizing process proceeds in an orderly manner. However, during use, if the sizing roller experiences friction, it will cause uneven adsorption and distribution of the sizing agent on its surface, requiring replacement.

[0003] The existing sizing roller replacement mechanism mainly consists of a slide rail, a slider, a drive unit, and a fixing clamp. The slide rail is generally installed on both sides of the machine frame in a horizontal straight line, providing guidance for the entire replacement process. The slider fits tightly with the slide rail, allowing it to slide smoothly along the slide rail. The fixing clamp is installed on the slider to firmly hold the sizing roller. The drive unit is the power source for the entire mechanism, commonly an electric push rod or a hydraulic cylinder. When the sizing roller needs to be replaced, the drive unit is activated, pushing the slider to move along the slide rail, thereby removing the old sizing roller from its working position and accurately delivering the new sizing roller to the designated position. This sizing roller replacement mechanism has significant advantages. However, after prolonged use, the slide rail is prone to being clogged by foreign objects and dust, making the replacement of the sizing roller more cumbersome, time-consuming, and labor-intensive. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a base fabric sizing device for a coating and bonding machine, which aims to improve the existing technology where the method of replacing the sizing roller is prone to blockage by foreign objects and dust after long-term use. In this case, replacing the sizing roller is more cumbersome, time-consuming and labor-intensive.

[0011] A connecting plate two is fixedly connected to the left front end of the frame. A circular hole is opened inside the connecting plate two, and the inner wall of the circular hole is slidably connected to the outer wall of the fixing rod.

[0012] As a further description of the above technical solution:

[0013] The frame has a slurry groove inside, and a slurry roller is fixedly connected to the inner wall of the slurry groove.

[0014] As a further description of the above technical solution:
