Hot air non-woven fabric setting machine with automatic deviation correction function for net curtain

Abstract

A hot air non-woven setting machine with a paired held net curtain automatic correction function comprises a machine frame, an upper held net curtain driving mechanism, a lower held net curtain driving mechanism, upper hot air boxes, lower hot air boxes, an upper hot air box lifting adjusting mechanism, an upper held net curtain and a lower held net curtain, wherein the upper held net curtain driving mechanism and the lower held net curtain driving mechanism correspond to the right side of the machine frame and are connected with the machine frame; the upper hot air boxes and the lower hot air boxes are arranged along the upper portion and the lower portion of the length direction of the machine frame from left to right; the upper hot air box lifting adjusting mechanism is arranged on the upper portion of the machine frame and connected with the upper hot air boxes. The setting machine is characterized by further comprising an upper held net curtain correction mechanism and a lower held net curtain correction mechanism, the upper held net curtain correction mechanism corresponds to the left side of the machine frame and is connected with the machine frame, the lower held net curtain correction mechanism corresponds to the lower portion of the upper held net curtain correction mechanism and is connected with the left side of the machine frame, one end of the upper held net curtain is arranged on the upper held net curtain correction mechanism in a sleeving mode, the other end of the upper held net curtain is arranged on the upper held net curtain driving mechanism in a sleeving mode, one end of the lower held net curtain is arranged on the lower held net curtain correction mechanism in a sleeving mode, and the other end of the lower held net curtain is arranged on the lower held net curtain driving mechanism in a sleeving mode. Friction, caused by deflection of the upper held net curtain and the lower held net curtain, of the setting machine and a wallboard is avoided.

Description

technical field [0001] The invention belongs to the technical field of non-woven product processing machinery, and in particular relates to a hot-air non-woven fabric setting machine with the function of automatically correcting the deviation of a net curtain. Background technique [0002] The non-woven fabric produced by the hot air method is usually called a through-hot airbording nonwoven fabric (English name: through-hot airbording nonwoven). It is a hot air non-woven fabric forming machine (also known as a hot air non-woven fabric forming machine). For the standard definition, technical requirements and test methods of air-through non-woven fabrics, please refer to China Textile Standard FZ / T64046-2014. [0003] As known in the industry, fiber webs made of thermoplastic synthetic fibers can usually be reinforced by thermal bonding, such as polyester, nylon, polypropylene, ES fibers, etc. commonly used in nonwoven production. Furthermore, as is known in the art, since ...

AI Technical Summary

Problems solved by technology

Due to the long length of the shaping cavity, the length of the upper and lower mesh curtains is also relatively long, so the upper and lower mesh curtains will inevitably appear in the process of moving round and round between the entrance side and the exit side of the shaping cavity. In the case of deviation, if the deviation cannot be corrected in time, it will undoubtedly affect the operation effect, and even damage the upper and lower mesh curtains, such as the edge of the upper and / or lower mesh curtains and the edge of the deviation. The friction of the wallboard makes the setting work of the hot air non-woven fabric unsustainable (forced to stop)
