Brush of flat knitting machine

Abstract

The utility model discloses a brush of a flat knitting machine, which comprises a base provided with bristles arranged in a horizontal row. Nylon bristles are arranged in the middle of the horizontal row, and hog bristle bristles are arranged on two sides of the horizontal row. The total length of the bristles is L, the lengths of the bristle bristles on the two sides are A, the length of the nylon bristles in the middle is B, B is 1 / 6-1 / 2 of L, and the length of the A on the two sides is averagely distributed to the rest part. According to the utility model, two kinds of bristles are reasonably combined and used, so that the brush can achieve a better use effect.

Description

Technical Field

[0001] The utility model belongs to parts of a flat knitting machine, in particular to a brush of the flat knitting machine. Background Art

[0002] The brush is one of the commonly used parts in knitting machines. It cooperates with the knitting needles to open the needle tongue. The brush achieves this function by contacting the knitting needles with the bristles on its head and applying pressure. The existing brush bristle materials are generally pig bristle and nylon. The pig bristle is relatively hard and has a good effect of brushing open the needle tongue, but the knitting needle has a relatively large resistance when passing through the brush. When using ultra-fine knitting needles, they are easily deformed by the brush; while nylon bristles are just the opposite. Summary of the invention

[0003] The purpose of the utility model is to overcome the above defects and provide a brush with better effect.

[0004] After careful research, the applicant found that the action of the brush opening the needle tongue can be divided into two stages. In the first half of the relative movement of the two, the brush is used to open the needle tongue from a closed state, while in the second half, the brush is used to keep the needle tongue in an open state to prevent it from rebounding and closing again. Based on this research, the technical solution of the utility model is proposed.

[0005] The technical solution adopted by the utility model is as follows: the brush of the knitting machine comprises a base with bristles arranged in horizontal rows; the characteristic is that the middle part of the horizontal row is softer bristles, and the two sides are harder bristles.

[0006] Furthermore, assuming that the total length of the bristles is L, the lengths of the harder bristles on both sides are A, and the length of the softer bristles in the middle is B, then B is 1 / 6 to 1 / 2 of L, and the remaining part is evenly distributed as the length of A on both sides.

[0007] The aforementioned softer and harder are relative, that is, the hardness of the bristles on both sides is greater than that of the bristles in the middle.

[0008] Furthermore, the harder bristles are pig bristle bristles, and the softer bristles are nylon bristles.

[0009] During the movement of the brush, the bristles on both sides always touch the knitting needles first. Therefore, the utility model uses harder bristle bristles on both sides to ensure the opening of the needle tongue; and uses nylon bristles in the middle. Although softer, it is enough to keep the needle tongue open and will not affect the deflection of the knitting needle itself. As for the specific length distribution of A\B, it needs to be determined according to the specific model, and it is generally within the aforementioned range.

[0010] It can be seen that the utility model reasonably combines and uses two types of bristles, so that the brush can achieve better use effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] See the attached drawings. The brush of this embodiment includes a base 10 and a horizontal row of bristles 1 fixed on the base, wherein the bristles on both sides are pig bristles and the bristles in the middle are nylon bristles. The needle movement track used in this embodiment is 2. The knitting needle enters from the left or right side. It can be seen that the track is obviously upward after a certain stroke, which means that the needle tongue has been opened at this time. The function of the brush is to prevent the needle tongue from rebounding; accordingly, the brush is switched to nylon bristles here. In this embodiment, the length B of the nylon bristles is 30% of the total length L, and the length A of the pig bristles on both sides is 35% of the total length L.

[0014] Another implementation form of the present invention is to first manufacture small brushes with different bristles, and then assemble their bases together in a transverse arrangement, which is also within the scope of the present invention.

Claims

1. A brush for a flat knitting machine, comprising a base with bristles arranged in horizontal rows; characterized in that: The middle part of the horizontal row has softer bristles, and the sides have harder bristles.

2. The brush for a flat knitting machine according to claim 1, characterized in that: Suppose the total length of the bristles is L, the length of the harder bristles on both sides is A, and the length of the softer bristles in the middle is B.
