Auxiliary Roller Device of Computerized Flat Knitting Machine

Abstract

The invention provides an assistant roller device of a computer-controlled flat-bed knitting machine, and belongs to the technical field of knitting machines. The assistant roller device comprises a roller body, a transition roller, a support member and a cloth holding sleeve. The lower portion of the support member is supported by the roller body, the upper portion of the support portion cooperates with the transition roller, the transition roller and the roller body are sleeved by the cloth holding sleeve, and the cloth holding sleeve wraps the support member. The assistant roller device is characterized by further comprising a central support mechanism of the roller body, the central support mechanism of the roller body is fixed to a needle bed of a computer-controlled flat-bed knitting machine. The roller body is composed of a first roller body segment and a second roller body segment which are the same in length. The cloth holding sleeve is composed of a first cloth holding sleeve unit and a second cloth holding sleeve unit, the first cloth holding sleeve unit corresponds to the first roller body segment, and the second cloth holding sleeve unit corresponds to the second roller body segment. The central support mechanism of the roller body is arranged between the first roller body segment and the second roller body segment and connected to the first roller body segment and the second roller body segment at the same time. The assistant roller device can provide a uniform drawing force to a whole broad-width braided fabric to smoothly draw the braided fabric downwards from an opening of a needle bed of a computer-controlled flat-bed knitting machine.

Description

technical field [0001] The invention belongs to the technical field of knitting machinery, and in particular relates to an auxiliary roller device of a computerized flat knitting machine. Background technique [0002] A computerized flat knitting machine is usually equipped with a main roller device and an auxiliary roller device. The specific position of the sub-roller device on the computerized flat knitting machine corresponds to the lower part of the center of a pair of front and rear needle beds (also called front and rear needle plates) distributed in a figure-eight (or herringbone) shape, and As close as possible to the barrel mouth, that is to say, the position of the auxiliary roller device is required to be as close to the barrel mouth as possible. For the concept of the barrel mouth, please refer to the third paragraph on page 7 of the description of the Chinese invention patent application publication number CN101225576A. The aforementioned main roller device i...

Problems solved by technology

Although reasonably increasing the diameter and rigidity of the roller body can avoid deflection to a certain extent, as mentioned above, due to the very limited space at the mouth of the cylinder, the diameter of the roller body is objectively restricted, because the direct increase will inevitably increase accordingly. The larger the distance between it and the cylinder mouth, the greater the distance away from the cylinder mouth, the worse the pulling effect on the braid, and increasing the diameter of the roller body will increase the power consumption of the aforementioned power transmission mechanism, which is not conducive to energy saving

[0007] The utility model patent authorization announcement number CN2890114Y recommended "Computerized Flat Knitting Machine Integral Semi-circular Supporting Auxiliary Roller" is changed from two-section connection to an integral pull rod compared with the prior art, and an integral pull rod Although the cloth rod can reduce the number of parts, it is prone to deflection

However, since the cross-sectional shape of the two-stage connected cloth rod (the patent is called the auxiliary cloth rod) is quincunx and directly contacts the fabric in the cloth state, it is not the structural system of the aforementioned auxiliary roller device. Therefore, when a pair of pull rods that cooperate with each other is easy to form tooth marks on the cloth surface when pulling the cloth, it is not suitable for the traction of fabrics with high grade requirements.

In addition, the computerized flat knitting machine auxiliary cloth structure mentioned in the background technology column of the patent is composed of two auxiliary cloth rods, two connecting small shafts and a bearing. The bearings correspond to the two auxiliary cloth rods and the two Connect the joints of the small shafts, specifically, fix the opposite joint ends of the two auxiliary pull rods with the outer ring (rotatable) of the bearing, and fix the opposite joint ends of the two small shafts with the inner ring of the bearing (non-rotating) fixed, so since the length of the two connecting small shafts needs to be equal to the length of the two auxiliary pull rods, on the one hand, the entire auxiliary roller device is cumbersome and is not conducive to saving the power used to drive the auxiliary pull rods. The power consumption of the transmission mechanism, on the other hand, causes an increase in manufacturing costs

Therefore, the aforesaid structure introduced in the background technology column of this CN2890114Y has no substantive inspiration for solving the deflection of the roller body in the structural system of the auxiliary pull device mentioned above
