Description

Technical Field

[0001] This utility model belongs to the field of textile processing, and specifically relates to a calendering device for textile fabrics. Background Technology

[0002] Textile calendering is a processing method that uses heating and pressure to give textiles specific properties and finishing effects. Its main functions include improving the appearance and feel of fabrics, adjusting the physical properties of fabrics, giving them functions such as waterproofing, stain resistance, and flame retardancy, and achieving special surface effects.

[0003] Patent application CN202022864427.X discloses a calendering device for nonwoven fabric production, including a fabric output machine. One side of the output machine has a calendering structure for pressing the woven fabric, another side has a cleaning structure for removing dust from the fabric surface, and a third side has a winding structure for winding the fabric together. A first and second calendering bar, in conjunction with a heating plate, makes the fabric calendered more compact and durable, resulting in better calendering performance. When the fabric passes through the cleaning plate, soft bristles remove dust from the fabric surface. However, the cleaning structure is located after the calendering structure, and dust and other impurities become more difficult to remove after calendering. Relying solely on soft bristles results in poor cleaning effectiveness. Furthermore, heating the fabric by placing the heating plate on the calendering bar is a single, ineffective method that fails to stretch the fabric's wrinkles, affecting the calendering effect. Additionally, the high temperature after calendering necessitates cooling and setting to prevent springback deformation, but the lack of a cooling structure reduces the calendering quality. Utility Model Content

[0004] To address the problems mentioned in the background art, this utility model provides a calendering device for textile fabrics, which can quickly perform cleaning, heating, calendering and cooling processes. It has a compact and reliable structure, improves the calendering effect and increases work efficiency.

[0005] To achieve the above objectives, the specific technical solution of this utility model is as follows:

[0006] A calendering device for textile fabrics includes a calendering box. A cleaning device is provided at the left feed inlet of the calendering box, and a cooling device is provided at the right discharge outlet of the calendering box. Inside the calendering box, near the left feed inlet, there is a support roller that is rotatably connected in a front-to-back direction. Inside the calendering box, near the right discharge outlet, there is a lower pressure roller device that is rotatably connected. Two fixed heating rollers are rotatably connected at the middle position between the support roller and the lower pressure roller device. The central axes of the support roller, the fixed heating roller, and the lower pressure roller device are parallel to each other and are in the same horizontal plane. A tension heating roller device is provided directly below the two fixed heating rollers, and a parallel, liftable upper pressure roller device is provided directly above the lower pressure roller device.

[0007] As a further feature of the above scheme, a fixed bracket is provided on the upper end plate of the calender box, and a hydraulic cylinder device is fixedly connected to the fixed bracket. The lower end of the hydraulic cylinder device is fixedly connected to the upper pressure roller device. Vertical grooves are symmetrically arranged on the front and rear side plates of the calender box.

[0008] As a further feature of the above scheme, the upper pressure roller device includes a guide vertical plate, which is slidably connected to the upper end plate of the calender box. An mounting plate is fixedly connected to the upper end of the guide vertical plate, and a rotating bracket is fixedly connected to the lower end of the guide vertical plate. An upper pressure roller is rotatably connected to the rotating bracket. Buffer spring devices are symmetrically arranged on both sides of the guide vertical plate and the lower end of the mounting plate. The lower end of the buffer spring device is fixedly connected to the upper end plate of the calender box.

[0009] As a further provision of the above solution, the cleaning device includes a cleaning box that runs through the left and right sides. A cleaning brush with symmetrical upper and lower sides is provided at the left opening of the cleaning box, and a scraper device with symmetrical upper and lower sides is provided at the right opening of the cleaning box.

A limiting plate is provided at the upper end of the guide rod, and a blade holder plate is fixedly connected to the lower end of the guide rod. A scraper is fixedly connected to the blade holder plate. A pressure spring is sleeved on the guide rod. One end of the pressure spring is fixedly connected to the blade holder plate, and the other end is fixedly connected to the inner wall of the cleaning box.

[0010] As a further feature of the above solution, an air inlet is provided on the front side panel of the cleaning box, and an exhaust device is provided on the front side panel of the cleaning box. The air inlet and the exhaust device are located at both ends of the scraper.

[0011] As a further provision of the above scheme, the cooling device includes a cooling box that runs through the left and right sides. Air blowing devices are symmetrically installed on the upper and lower plates of the cooling box.

[0013] This utility model has the following beneficial effects:

[0014] Cleaning and cooling devices are installed on both sides of the calendering box. Before calendering, the cleaning brush performs an initial cleaning of the textile fabric, and the scraper device performs a secondary cleaning of the rough edges and loose threads on the textile fabric. At the same time, the exhaust device ventilates and removes dust from the inside of the cleaning box, further improving the cleaning effect. After calendering, the blowing device blows cold air evenly onto the textile fabric through the jet nozzle, quickly completing the cooling and shaping process, preventing springback deformation, greatly improving the calendering quality, and increasing work efficiency.

[0015] The textile fabric passes over the support roller, the left fixed heating roller, the moving heating roller, and the lower pressure roller. The two fixed heating rollers heat the bottom of the textile fabric, while the moving heating roller heats the top of the textile fabric, ensuring uniform heating. At the same time, the tensioning device tightens the textile fabric to remove wrinkles, improving the calendering effect. Attached Figure Description
