Abstract

The utility model relates to a short gauge type spring cradle of spinning machine, wherein, the center distance M of the front compression bar arranged inside a front press part is less than or equal to 90 mm; the length N of a pressure regulating lever is less than or equal to 39 mm; when a handle is pressed down, the distance L between the press center B of a middle press part and the press center A of the front press part is more than or equal to 35 mm and is less than or equal to 38 mm.The utility model only changes the center distance between the middle press part and the front press part with other parts of structure and connection size being identical to those of traditional YJ2-142 series spring cradle, thereby, the cradle can realize association application with double short apron small gauge drafting apparatus of cotton spinning machine and can complete alteration of cotton spinning machine of models such as FA502, FA 503 and FA507 etc.; test shows that adopting the utility model on cotton spinning machine provided with double short apron drafting apparatus can reduce snicks of pure cotton spun yarn spun by the spinning machine by 30 percent with 0.3 percent to 0.5 percent drop in CV evenness value.

Description

The short type fine spining machine Spring cradle that spaces

Technical field:

The utility model relates to the Spring cradle that a kind of cotton spinning frame is used.

Background technology:

At present, drafting system in the domestic cotton spinning frame, its pressurization form adopts Spring cradle to pressurize mostly.In the Spring cradle that uses now, the distance at the pressurization center of forward press parts to the pressurization center of middle pressure part is between 46～73mm, adapt with the drafting system in the existing cotton spinning frame, because the centre-to-centre spacing in the drafting system of existing cotton spinning frame between front roller and the middle roller is too big, cause district pressurization on, following apron radial effect power is too little, control ability to thick cotton yarn is relatively poor, make cotton spinning frame when the textile spun yarn of spinning, the details of cotton yarn, slubbing, parameters such as the dried value of CV bar all do not reach requirement, the high-quality textile spun yarn of the incompatible weaving of the drafting system of existing cotton spinning frame and spring, therefore the applicant has done improvement to the drafting system of cotton spinning frame, and declared national inventing patent, the utility model also is that existing cotton spinning frame is had not enough improvement.

Summary of the invention:

Goal of the invention of the present utility model provides a kind of weak point type fine spining machine Spring cradle that spaces.

The fine spining machine Spring cradle that weak point described in the utility model spaces comprises preceding pressure part, middle pressure part, back pressure part, reel cage pedestal and rocking arm and base, preceding pressure part, middle pressure part and back pressure part are installed on the reel cage body, the reel cage body is connected with rocking arm and base, in preceding pressure part, comprise forward press and pressure regulation lever, it is characterized in that: the centre-to-centre spacing M≤90mm of the forward press before described in the pressure part, length N≤the 39mm of pressure regulation lever, when handle was in depressed state, the center that the presses down B of middle pressure part apart from the distance L between the center that the presses down A of preceding pressure part was: 35mm≤L≤38mm.

Because the utility model has only changed the centre-to-centre spacing between middle pressure part and the preceding pressure part, other structure and size for connection all the YJ2-142 series Spring cradle with traditional are identical, therefore, this reel cage can with the supporting use of cotton spinning frame double-short leather-ring close setting drafting system, can be to cotton spinning frame FA502, FA503, types such as FA507 are transformed, use this Spring cradle in conjunction with double-short leather-ring close setting drafting system, can improve the textile quality of existing cotton spinning frame, through test, this weak point type fine spining machine Spring cradle that spaces is used to be provided with the cotton spinning frame of double short belt drafting device, the details of the textile spun yarn that is woven by this Spinning Frame descends about 30%, and the CV bar is done value and descended 0.3%～0.5%.

Description of drawings:

Fig. 1 is the structural representation of existing YJ2-142 series reel cage; Fig. 2 is a structural representation of the present utility model;

Fig. 3 is the part instance graph of pressure regulation lever among Fig. 2; Fig. 4 is the part instance graph of forward press among Fig. 2.

Among the figure: 1-clearer spring; Pressing spring before the 2-; 3-pressure regulation push rod; Pressing spring among the 4-; The 5-bracket screw; The 6-medium-height trestle; The 7-handle; The 8-after-poppet; 9-reel cage body; The 10-rocking arm and base; 11-locks backing pin; The 12-lock-screw; The 13-adjustment screw; Pressing spring behind the 14-; Depression bar among the 15-; 16-pressure regulation lever; 17-presss from both sides spring; The 18-forward press; The 19-top stem casing; The 20-spring compressor.

The specific embodiment:

Below in conjunction with accompanying drawing the specific embodiment of the present utility model is elaborated:

The fine spining machine Spring cradle that weak point described in the utility model spaces comprises preceding pressure part, middle pressure part, back pressure part, reel cage body 9 and rocking arm and base 10, preceding pressure part, middle pressure part and back pressure part are installed on the reel cage body 9, reel cage body 9 is connected with rocking arm and base 10, the centre-to-centre spacing M=89mm of the forward press 18 of preceding pressure part, other size is same as the prior art; Length N=the 37.5mm of pressure regulation lever 16, overall structure of the present utility model is identical with existing YJ2-142 series Spring cradle, when handle 7 is in depressed state, the center that the presses down B of middle pressure part is apart from the distance L=37mm between the center that the presses down A of preceding pressure part, and the pressure of preceding pressing spring 2 also should be made accommodation.
