Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a carding sheet gauge adjustment device for adjusting the gap between a carding sheet needle and a cylinder needle incorporated in, for example, a flat card.

[Conventional technology]

For example, as shown in FIG. 3, a carding sheet 1 incorporated into a flat card includes a sheet main body 2 whose inner surface is a curved surface larger than the diameter of a cylinder (not shown), and a plurality of carding sheets fixed to the inner surface of this sheet main body 2. and a metallic clothing unit 3,
Further, curved surfaces 4, 4 corresponding to the contact surfaces of the cylinder bends are formed at both ends of the inner surface of the seat body 2. The curved surface 4 is provided with two bolt holes 5, 5 through which mounting bolts are inserted, and four screw holes 6 surrounding each bolt hole 5.

To adjust the gauge when fixing the carding sheet 1 on a flat card, as shown in FIG. Screw the mounting bolt 8 into a screw hole (not shown) provided on the contact surface of the cylinder bend, then turn the screw 7 screwed into the screw hole 6 with a screwdriver so that the tip of the screw 7 hits the cylinder bend. This is done by bringing it into contact with a surface.

[Problem that the invention attempts to solve]

However, in the above-mentioned type of gauge adjustment device for carding seats, the four adjustment screws surrounding the mounting bolts inserted into the bolt holes are connected to the line connecting the two adjustment screws located on the outside and on the inside. Since the lines connecting the two adjusting screws are arranged to have the same length, it is difficult to adjust the gauge accurately.This invention was developed in view of the above points.
To provide a gauge adjustment device for a carding sheet, which allows accurate gauge adjustment by specifying the positional relationship of four adjustment screws provided so as to surround a mounting bolt inserted into a bolt hole. With the goal.

[Means for Solving the Problems] The carding seat gauge adjustment device of the present invention replaces the four adjustment screws provided so as to surround the mounting bolts inserted into the bolt holes with the two screws located on the outside. The line connecting the two adjustment screws located on the inside and the line connecting the two adjustment screws located on the inside are parallel to the metallic clothing piece fixed to the carding sheet, and the distance between the two adjustment screws located on the outside is It is characterized by being set wider than the interval between the two adjustment screws located on the inside.

[Effect]

In the carding sheet gauge adjustment device of the present invention, first, the gauges of the needle surface of the carding sheet and the needle surface of the cylinder are adjusted using two adjustment screws located on the outside. As a result, the gauge on the side of the carding sheet is set to a predetermined gauge. In this case, the gauge at the center of the carding sheet is wider than the gauge at the sides, so
Adjust the gauge in the center by adjusting the gauge in the outer 2
This is done using the two inner adjustment screws that are set narrower than the spacing between the adjustment screws on the book. This sets the center gauge to a value close to the side gauge.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings.

In FIG. 1, the same members as in FIG. 4 are given the same reference numerals.

In FIG. 1, the reference numeral 10 indicates the outer
A line parallel to the metal cloth piece fixed to the carding sheet connecting the adjustment screws 7, 7 is shown, and the distance between the adjustment screws 7, 7 on this outer line 10 is several times the diameter of the bolt hole. It is set to L1.

On the other hand, the distance L2 between the adjustment screws 7, 7 on the line 11 parallel to the metal cloth piece fixed to the carding sheet connecting the two adjustment screws 7, 7 located on the inside is set to a value smaller than the above distance L1. has been done.

In other words, the bolt hole 5 is provided so as to surround the bolt hole 5.
As shown in FIG. 2, the screw holes 6 of the book are arranged so as to have a trapezoidal shape as a whole.

Therefore, in order to attach the carding sheet to the cylinder bend and adjust the gauge of the carding sheet, first attach the carding sheet 1 to the bolt hole 5.
is placed on the cylinder bend so that it matches the screw hole of the cylinder bend, and the mounting bolt 8 is screwed into the screw hole through the bolt hole 5 to temporarily attach the carding sheet to the cylinder bend. Next, the gauge between the needle face of the carding sheet and the needle face of the cylinder is adjusted using two adjustment screws 7, 7 located outside the carding sheet 1 using a gauge plate. As a result, the gauge on the side of the carding sheet 1 is set to a predetermined gauge. When the sides of the carding sheet 1 are set to a predetermined value, the gauge at the center of the carding sheet is usually wider than the gauge at the sides, so adjust the gauge at the center to the outside. This is done using the two inner adjustment screws that are set narrower than the distance between the two adjustment screws. Gauge adjustment using two closely spaced inner adjustment screws is effective in correcting longitudinal bends in the carding sheet, and allows the center gauge to be set to a value close to the side gauges. That will happen.

[Effect of idea]

As described above, according to the present invention, the four adjustment screws arranged to surround the mounting bolts inserted into the bolt holes provided in the carding sheet are adjusted so that the distance between the two adjustment screws located on the outside is Since the distance is set wider than the distance between the two adjustment screws located on the inside, it is possible to accurately adjust the gauge of the carding sheet, and therefore carding can be performed under optimal conditions, and the yarn quality can be improved. play.
