Therefore, conventionally, a filter box having a different exhaust hole position is prepared in advance, and the filter box is used in accordance with the specifications. Therefore, it is necessary to prepare a plurality of types of filter boxes in advance, and it is necessary to secure an extra storage space. Further, when the specifications of the exhaust duct are changed, it is necessary to change the entire filter box, and the filter box used up to that point is wasted.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and has as its object to collect cotton in a textile machine in which cotton boxes having different positions of exhaust holes can be manufactured using the same parts. An object of the present invention is to provide a cotton collection box.

[0008]

In order to achieve the above object, according to the first aspect of the present invention, a negative pressure is applied to an intake passage connected to an intake passage for sucking fiber waste generated by a textile machine. What is claimed is: 1. A cotton collection box having a built-in filter for trapping fiber waste conveyed in an intake passage, comprising: a first frame on an exhaust side having an exhaust hole formed therein; and a second frame on an intake side connected to the intake passage. The frame and the frame were formed separately, and both frames were integrally assembled.

According to the second aspect of the present invention, the first frame can be assembled upside down with respect to the second frame. According to a third aspect of the present invention, in the first or second aspect, a fan is housed on the first frame side.

According to the first aspect of the present invention, the fiber waste is conveyed in the intake passage by the action of the negative pressure generated in the cotton collecting box, reaches the cotton collecting box, and is captured by the filter. Since the first frame on the exhaust side in which the exhaust hole is formed and the second frame on the intake side connected to the intake passage are formed separately, the mounting position of the first frame on the second frame is changed. Thereby, the position of the exhaust hole is changed.

According to the second aspect of the present invention, the position of the exhaust hole is set to either the upper side or the lower side of the cotton collecting box by changing the position where the first frame is attached to the second frame.

According to the third aspect of the present invention, in the first or second aspect of the present invention, since the fan is housed in the first frame side room provided with the exhaust hole, Exhaust is performed efficiently.
