Abstract

PURPOSE:To enable complete removal of fly waste, dust, etc., sticking to top rollers or bottom rollers of a drafting device and scraping off of the fly waste, dust, etc., captured with a felt belt. CONSTITUTION:The subject device is composed of an endless felt belt 6, brought into pressure contact with respective top rollers or bottom rollers (1a), (2a), (3a), (4a) and (5a) and subjected to continuous normal or reverse rotation and a comb kept in pressure contact with the felt belt 6.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cleaning device for removing dust and dust adhered to a top roller and a bottom roller of a drafting device such as a spinning machine.

[0002]

2. Description of the Related Art An endless felt belt, which is wound around in contact with the bottom side of each bottom roller which constitutes a draft device, is moved in one direction so that a relative speed can be obtained with respect to each bottom roller. There is already known a device that removes the cotton dust, dust, and the like adhering to the felt belt, and scrapes off the cotton dust, dust, and the like trapped on the felt belt with a comb arranged in contact with the felt belt.

[0003]

In the above-mentioned known bottom roller cleaning device, the moving direction of the felt belt is one direction, and removal of cotton wool, dust and the like adhering to each bottom roller and the wind captured by the felt belt. The scrapes of cotton, dust, etc. are not perfect, and dissatisfaction remains.

The present invention provides a roller cleaning device for a draft device, which can completely remove fly dust and dirt adhering to the top roller or bottom roller and scrape away fly dust and dust caught on the felt belt. The purpose is to do.

[0005]

In order to achieve the above object, a roller cleaning device of a draft device of the present invention comprises an endless felt belt pressed against each top roller or bottom roller, and a comb pressed against it. And the felt belt is continuously positive and reverse.

[0006]

[Operation] In the roller cleaning device of the draft device configured as described above, even the fibers wound around the top roller or the bottom roller are disentangled when the felt roller is reversed and the wind firmly adhered to the felt belt surface. Cotton and dust can also be effectively stripped by repeated rubbing against the comb.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment in which the roller cleaning device of the draft device of the present invention is applied to the bottom roller of the draft device will be described with reference to FIGS. In addition,
A substantially similar configuration can be adopted for the top roller.

This cleaning device is used in, for example, a spinning machine, each bottom of a super high draft device including a front roller 1, a second roller 2 with an apron, a third roller 3, a force roller 4 with an apron, and a back roller 5. Rollers 1a, 2a, 3
a, 4a, 5a, an endless felt belt 6 hung around, a comb 7 arranged in contact with the felt belt 6 and having a blade-like tip, and an air suction device arranged near the lower side of the comb 7. It is composed of 8 and.

The felt belt 6 is stretched between the driving pulley 9 and the driven pulley 10 and is pressed by the pressing member 11 fixed to the machine frame to form the bottom rollers 1a and 2b.
It is pressed against the a, 3a, 4a, and 5a sides. This keeps a positive contact with the bottom roller.

The comb 7 is biased toward the pressing member 11 side via the felt belt 6 by a leaf spring 12 having one end fixed to the machine frame. Therefore, the comb 7 moves up and down according to the change in the thickness of the felt belt 6, and the blade edge always comes into contact with the felt belt 6. In addition, 13 in FIG. 2 is a guide bar of the comb 7 fixed to the pressing member 11.

This bottom roller cleaning device is characterized in that the felt belt 6 is continuously and alternately rotated in a forward direction indicated by a long arrow and a reverse direction indicated by a short arrow opposite thereto. As indicated by the length of each arrow, the amount of movement in the forward direction is set larger than the amount of movement in the opposite direction.

In this way, the felt belts 6 are alternately positive,
When it is reversed, each bottom roller 1a, 2a, 3a, 4
In 5a and 5a, even the fibers wound around the bottom roller are disentangled when the felt roller 6 is rotated in the reverse direction, and between the felt belt 6 and the comb 7, the cotton wool and dust firmly adhered to the surface of the felt belt 6 Etc. are effectively peeled off by reciprocating rubbing with the comb 7, and sucked into the air suction device 8.

[0013]

Since the present invention is constructed as described above, it has the following effects.

That is, not only the cotton wool and dust attached to the top roller or the bottom roller but also the wound fibers are effectively disentangled, and the cotton wool and dust adhered firmly to the felt belt surface are also effective. Stripped off.
