DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a spinning nozzle cleaning device used for cleaning a nozzle surface having a plurality of spinning holes for spinning a synthetic resin filament such as a polyester filament or a nylon filament.

[0002]

2. Description of the Related Art Conventionally, as shown in FIG. 5, a spinning nozzle cleaning device has a spatula Da and a handle which is formed into a single flat plate and is used to scrape off the deposits attached to the nozzle surface Na. Some parts are integrated with the part Dc. The cleaner grasps the support portion Dc and places the blade edge Db of the spatula portion Da on the nozzle surface Na.
To move the hand to scrape off the deposits on the nozzle surface Na.

[0003]

In order to surely scrape off the blade, it is necessary to slide the blade edge Db in line contact with the nozzle surface Na, which requires skill. However,
Since the worker does not touch the spun yarn at a high temperature spun from the nozzle N, it is very difficult for even a skilled person to bring the blade edge Db of the spatula into line contact with the nozzle surface Na. . In particular, since the spinning nozzle N is installed at a high place, it becomes even more difficult in a high place cleaning operation.

[0004] Therefore, an object of the present invention is to provide a spinning nozzle cleaning device capable of reliably scraping off without requiring skill.

[0005]

In order to be able to reliably scrape off without requiring skill, claim 1 is provided.
Means adopted by the present invention described above is a spinning nozzle cleaning device provided with a spatula for cleaning a nozzle surface having an opened spinning hole, and a support for supporting the spatula. That is, they are swingably connected. According to the present invention, even when the angle of the support portion changes during cleaning performed by pressing the blade edge of the spatula portion against the nozzle surface, the spatula portion can swing to bring the blade edge into linear contact with the nozzle surface. In the above-mentioned means, a bifurcated portion may be provided on the support portion, and a spatula portion for rough scraping and a scraper for finish scraping may be connected to the bifurcated portion so as to swing freely.

[0006] The means adopted by the present invention according to the second aspect of the present invention is intended to protect the hand and the like moved inside the region where the spun yarn flows down so as to be able to reliably scrape the work.
In the spinning nozzle cleaning device described above, a protective device for receiving the spun yarn is provided on the support portion. According to the present invention, even if the hand moves into the region where the spun yarn flows down, the spun yarn that flows down can be received by the protective device so as not to come into contact with the hand or the like gripping the support portion.

The means adopted by the present invention according to the third aspect of the present invention is such that it can be easily and reliably scraped off even at a high place cleaning operation. In the above, the support portion and the rotational drive source are connected by a flexible rotational force transmission cable, and the spatula portion is rotationally driven via the support portion. According to the present invention, the spatula can be forcibly rotated while the cutting edge is in line contact with the nozzle surface simply by pressing the spatula against the nozzle surface.
