Description

Geotextile hot roller ironing device

technical field

The invention relates to the technical field of geotextile ironing and flattening devices, in particular to a geotextile hot roller ironing device.

Background technique

Geotextile, also known as geotextile, is a permeable geosynthetic material made of synthetic fibers through needle punching or weaving. Geotextiles need to be ironed and flattened during processing. And most of the existing ironing and flattening devices use heating rollers or heating plates to iron and flatten the geotextile.

The patent "Hot Roller Ironing Mechanism for Geotextile Production" (application number: 2019223125315) discloses a hot roller ironing mechanism for geotextile production. The device transports the geotextile through a belt conveyor. And set water mist spraying to cooperate with heating plate heating, so as to realize automatic and fast ironing, save time and effort, and ironing efficiency is high. However, there are still some defects in this device in actual use. For example, in the above-mentioned patent, the heating plate is located above the geotextile. When in use, the heating plate is pressed on the top of the geotextile by the cylinder, although the telescopic rod and the spring provide a certain elastic force, so that The heating plate has a certain degree of elasticity and will not crush the geotextile. However, since the entire heating plate is pressed on the geotextile, the contact area between the geotextile and the heating plate is relatively large during the movement process, and the heating plate force application device, if the force exerted by the heating plate is large, the geotextile will be damaged during the transportation process. , easy to tear; if the force exerted by the heating plate is small, it is difficult to achieve the effect of ironing and flattening.

However, other ironing devices use a separate heating roller to work. Although the contact area between the heating roller and the geotextile is small, it is difficult to complete the ironing and flattening of the geotextile with a single heating roller. If multiple sets of heating rollers are used , it is not easy to adjust the downward pressure of multiple sets of heating rollers on the geotextile, and it is also easy to cause the geotextile to tear.
