Description

Technical Field

[0001] This utility model relates to a sizing and calendering device for high wear-resistant composite PE jute fabric, belonging to the technical field of fabric processing equipment. Background Technology

[0002] Jute fabric is a natural fiber that is environmentally friendly but may be rough and requires processing to improve its feel and appearance. It may also be not durable enough, so it needs to be reinforced with PE.

[0003] In the production of jute fabric, to improve the fabric's performance, PE is traditionally coated onto the fabric surface. However, double-sided coating increases the complexity of the process, and issues such as coating breaks, uneven coating, and excessive coating thickness may occur. The fabric sizing process needs further improvement. In addition, the fabric after sizing requires final calendering and setting. If the production temperature is too high, the PE will melt and stick together, and the fibers will melt. If the temperature is too low, the calendering effect will be affected, resulting in poor fabric smoothness and luster. Furthermore, the pressure applied during calendering needs to be further optimized. Throughout the entire production process, it is necessary to ensure the feasibility of the process and the finished product effect.

[0004] To address this, we propose a sizing and calendering device for high abrasion-resistant composite PE jute fabric. Summary of the Invention

[0033] The working principle of this utility model is as follows: The sizing and calendering device for high wear-resistant composite PE jute fabric shown in this utility model includes a device body 1, a base 2, a raw material roller 3, a sizing device 4, a squeezing device 5, a drying device 6, a calendering device 7, a take-up roller 8, a sizing replenishment device 9, a conveying device 10, a stirring device 11, and a control device 12. During the sizing and calendering process, the raw fabric is conveyed to various production and processing steps on the raw material roller 3 through the conveying device 10. First, it is sizing by soaking in the sizing liquid in the sizing device 4, and the sizing is evenly applied to the fabric. The sizing fabric is squeezed out of excess sizing liquid by the squeezing device 5, and the sizing liquid flows into the original sizing liquid. The squeezed sizing fabric is then conveyed to the drying device 6. After it is almost dried, it is conveyed to the calendering device 7 for calendering. The pressure and temperature are controlled to ensure that the calendering is smooth, the composite PE jute fabric is squeezed firmly, and the structural performance is good.

[0034] The sizing device 4 includes a sizing tank 4-1, a connecting rod 4-2, and a sizing guide roller 4-3. A water level sensor 41-1 is installed inside the sizing tank 4-1 to observe the amount of liquid in the tank and add sizing liquid in a timely manner to ensure that the fabric is completely submerged when passing through the sizing liquid, resulting in fast and uniform sizing. The squeezing device 5 includes at least two sets of squeezing rollers 5-1 and a drip trough 5-2. The bottom of the drip trough 5-2 is inclined and connected to the sizing tank 4-1 of the sizing device 4 to facilitate the flow and collection of sizing liquid and prevent waste. The squeezing rollers consist of a central roller shaft, The heating layer and fabric layer together provide compression, water absorption, and heating. During the liquid extraction process, it also ensures excellent smoothness of the sized fabric, making sizing easy and of high quality. The drying device 6 includes a drying chamber, several drying conveyor rollers, a heating assembly, and multiple air outlets. It rapidly heats and dries the sized fabric with air, ensuring uniform drying and good drying results. It further provides a certain shaping effect on the composite fabric, achieving plasticization and stability. The calendering device 7 includes an upper calendering roller group 7-1, an upper connecting frame 7-2, an upper connecting seat 7-3, and a hydraulic rod 7- 4. Hydraulic cylinder 7-5, lower calendering roller group 7-6, lower connecting frame 7-7, lower support seat 7-8, pressure sensor 7-9, and belt 7-10. Belt 7-10 is set on the roller group of lower calendering roller group 7-6, serving as a calendering platform to lay the shaped composite fabric flat on the platform. While being calendered by upper calendering roller group 7-1, it minimizes wrinkles and ensures stable calendering temperature, preventing heat dissipation. It also avoids excessively high or low temperatures, which are monitored by a temperature sensor. The calendering pressure value is controlled by hydraulic rod 7-4 and hydraulic cylinder 7-5 via pressure sensor 7-9, ensuring consistency in calendering temperature and pressure intensity. This results in high smoothness and gloss of the calendered fabric, improving fabric performance and providing certain waterproof, abrasion-resistant, and tear-resistant properties. Control device 12 includes a display, controller, and central processing unit. The touchscreen on the display allows setting sizing, drying, and calendering parameters, providing a comprehensive understanding of the entire production process and monitoring of fabric production.
