AI Technical Summary

Problems solved by technology

The above-mentioned structure has the defect that the clamping force to the braid is insufficient, because the cloth clamping covers 34 of a pair of braid pulling devices 3 configured in a figure-eight shape are in a line contact (the two are tangent) to each other in the length direction, that is, the two The contact is extremely limited, and the pulling force on the braid is obviously lacking, so that the Baotou needle forms a phenomenon of false tuck (that is, false tucking). However, it cannot be turned over completely, which will affect the quality of the braid, causing the braid to show uneven texture and unstable size, etc.

Embodiment 1

[0027] Please refer to figure 1 , provides a preferred but not absolutely limited power transmission device 1, which is composed of a gear case 11 and a case cover 12, and the case cover 12 is fixed on the opening or the mouth of the gear case 11 by a set of fixing screws. Since the internal structure of the gear box 11 is completely the same as that described by the applicant in the invention patent authorization announcement number CN100554556Y mentioned above and applied by the applicant (the 4th line from the bottom of the 4th page of the specification to the 1st paragraph of the 5th page), Therefore no more detailed description will be given. A pair of power output shafts 111 of the gearbox 11 are in drive connection with the braid pulling device 3 to be described below, and each power output shaft 111 is provided with a tongue and groove 1111 .

[0028] see you later figure 1 , the number of parts and the installation relationship of a pair of braided fabric traction...

Embodiment 2

[0033] please see figure 2 and combine figure 1 As a preferred tensioning device 321 for the cloth sleeve, a semi-arc groove 3211 and a tensioning roller 3212 arranged in the semi-arc groove 3211 are recessed on the corresponding two sides of the upper part of the transition rod support member 32, Preferably, the depth of the semicircular groove 3211 is half of the diameter of the tension roller 321 . This program can make the surface of cloth cover 34 and braid 8 ( Figure 4 Shown) form an angle α of about 3-5°. All the other are the same as the description to embodiment 1.

Embodiment 3

[0035] please see image 3 , as another preferred structure of the tensioning device 321 for the cloth sleeve, half arc protrusions 3213 protrude outward on the corresponding two sides of the upper part of the transition rod support member 32, and the structure of this embodiment can be abandoned in Embodiment 2. The tension roller 321 (also called the small shaft), more precisely, this embodiment has the same effect as embodiment 2. All the other are the same as the description to embodiment 1.

[0036] Please refer to figure 2 , the present invention consists of figure 1 The sub-roller mechanism shown is installed on the inside upper part of a pair of needle beds 6 that generally form a figure-eight and is close to the bottom of the barrel mouth 7 of the knitting mechanism. Specifically, the gear box is fixed by screws 11. The support 2 and the needle bed 6 are fixed.

[0037] applicant combined figure 1 and figure 2 Briefly describe the application of the present ...

Abstract

The invention relates to a paired roller mechanism of a computer flat knitting machine, belonging to the technical field of knitting machines. The mechanism comprises a power transmission device consisting of a gear case and a case cover, a supporting seat and a pair of knitted fabric traction devices which are arranged between the power transmission device and the supporting seat and in parallel to each other, wherein the pair of the knitted fabric traction devices respectively comprise a roller, a transition rod supporting member arranged on the roller, a transition rod arranged at the top of the transition rod supporting member and a holding cloth sleeve movably coated and sleeved outside the roller, the transition rod supporting member and the transition rod; and one end of each roller is in transmission connection with the power transmission device, while the other end is supported on the supporting seat. The mechanism is characterized in that the upper part of each transition rod supporting member and two corresponding sides along the length direction of the transition rod supporting member are respectively provided with a holding cloth sleeve tensioning device used for expanding the holding cloth sleeve towards the direction back to the transition rod supporting member. The invention has the advantages that the traction force to the knitted fabric is obviously improves, the phenomenon of false doubling stitches of the kitting mechanism is avoided, the lines of the knitted fabric are guaranteed to be uniform, and the quality of the kitted fabric is improved.

Description

technical field [0001] The invention belongs to the technical field of knitting machinery, and in particular relates to an auxiliary roller mechanism of a computerized flat knitting machine. Background technique [0002] The effect of secondary roller mechanism has been described in detail in the background technology column of the (application proposed by the applicant) disclosed in the Chinese invention patent authorization announcement number CN100554556C, and this patent is to previously disclosed CN2905846Y (the application proposed by the applicant) application), CN2910975Y and CN1928182A have been systematically and objectively evaluated. For details, please refer to line 6 on page 1 of the description of CN100554556C to line 15 on page 2 of the description. [0003] The technical solution provided by the above-mentioned patent (CN100554556C) is useful for reducing the power transmission loss of the power transmission device used to drive the braid traction device of ...
