Description

TECHNICAL FIELD

[0001] The utility model belongs to the tarpaulin roll cloth exhaust technology field, especially related to a tarpaulin roll cloth exhaust device. BACKGROUND

[0002] The existing tarpaulin roll cloth equipment lacks effective exhaust structure when rolling cloth, which mainly reflects that gas cannot be effectively exhausted in the rolling process, thereby causing the problem of tight wrapping. The generation of these shortcomings is due to the fact that the internal air cannot be released in time during the rolling process of the tarpaulin, causing local gas accumulation, so that the cloth is subjected to uneven pressure during winding, and wrinkles and bubbles are formed during the stress process, ultimately affecting the storage of the tarpaulin.

[0003] In order to solve this problem, the conventional method is to try to install exhaust holes on the cloth rolling equipment or to improve the design of the rolling shaft, so as to enhance the exhaust capacity of air. However, the disadvantages of these solutions are that the newly added exhaust holes may affect the strength and sealing of the whole equipment, causing dirt or moisture to enter during the production process, thereby affecting the durability and waterproof performance of the tarpaulin. Although the improved design of the rolling shaft can improve the gas exhaust to some extent, it often involves large-scale modification of the equipment, which requires high time and economic cost, and may also make the operation process more complex and increase the use difficulty. Therefore, we hope to design a tarpaulin roll cloth exhaust device with a new structure to solve this problem. UTILITY MODEL CONTENTS
