Abstract

The utility model discloses a hosiery machine density adjusting device. The hosiery machine density adjusting device comprises a main body, a slide block and a density triangle, wherein the density triangle comprises a density needle pressing triangle and a density needle withdrawing triangle; the density needle pressing triangle is fixed on the slide block; the density needle withdrawing triangle is fixed on the main body of the density adjusting device; the slide block can slide up and down in the main body; the hosiery machine density adjusting device further comprises an upper limiting bolt and a lower limiting bolt; the upper limiting bolt and the lower limiting bolt are both fixed on the main body; one part of the slide block is positioned below the upper limiting bolt; and the other part of the slide block is positioned above the lower limiting bolt and overlapped with projections of the two limiting bolts on a horizontal plane. According to the utility model, by using the additionally arranged limiting bolts, the slide block is effectively prevented from sliding beyond a set range so that fault is avoided between the two parts of the density triangle; therefore, the stability of the needle track of a knitting needle is guaranteed and the knitting quality is improved.

Description

The hosiery machine density regulating apparatus

Technical field

The utility model relates to technical field of knitting machinery, relates in particular to a kind of hosiery machine density regulating apparatus.

Background technology

Density triangular is a vitals in the hosiery knitting machines; It has determined the part Cam Track of hosiery knitting machines knitting needle in the braided fabric process, and the job stability of density triangular has determined the quality of the fabric quality that circular knitting machine knit out to a great extent.Density triangular comprises density depressing cam and density rise cam; Change the distance between two triangles through density regulating apparatus; To change density triangular is the Cam Track that knitting needle provides, thereby tackles different braiding needs, and general density rise cam is fixed on the body of density regulating apparatus; And the density depressing cam is fixed on the slide block in the density regulating apparatus, is moved up and down in density regulating apparatus by slide block to reach the purpose that changes density triangular two interblock distances.But find in the practical application; The slide block of density regulating apparatus usually can make the scope that is moved beyond setting of density depressing cam owing to a variety of causes shifts out the setting range of movement when sliding; Cause the decline of weaving quality, even can cause the damage of knitting needle or some other part.

Summary of the invention

The utility model aims to provide a kind of hosiery machine density regulating apparatus, can prevent that limited slip block is moved beyond the scope of setting.

For this reason, the technical scheme of its problem of the utility model solution is such: the hosiery machine density regulating apparatus comprises body, slide block, density triangular; Density triangular comprises density depressing cam and density rise cam, and the density depressing cam is fixed on the slide block, and the density rise cam is fixed on the body of density regulating apparatus; Slide block can slide up and down in body; Also comprise upper limit screw and lower limit screw, upper limit screw and lower limit screw all are fixed on the body, and some is positioned at the below of upper limit screw slide block; Some is positioned at the top of lower limit screw, and all has overlapping with two projections of stop screw on horizontal plane.

In the hosiery machine running, when slide block upwards slid into upper limit position, the overlapping part of projection was touched mutually on horizontal plane; Receive the restriction of upper limit screw, can't continue to slide, same; When slide block slides down to the lower position, receive the idle of lower limit screw, also can't continue to slide; Thereby make the moving range of density depressing cam can not exceed setting, make the spacing of density depressing cam and density rise cam keep normal.

The utility model is through increasing stop screw, effectively anti-limited slip block slide past setting range, and then prevent to cooperate between two parts of density triangular and break down, thereby ensured the stablizing of Cam Track of knitting needle, improved weaving quality.

Description of drawings

Below in conjunction with accompanying drawing and embodiment the utility model is described further.

Fig. 1 is the utility model front view.

Fig. 2 is the utility model vertical view.

The specific embodiment

Referring to accompanying drawing, have slide block 2 on the body 1 of density regulating apparatus, and density rise cam 3 fixedly is housed, slide block 2 can slide up and down in body 1, and density depressing cam 4 fixedly is housed on the slide block 2.Also have upper limit screw 5 and lower limit screw 6 on the body 1, slide block 2 has step surface 7 at upper limit screw 5 places, and step surface 7 is below upper limit screw 5, and slide block 2 has short slot 8 at lower limit screw 6 places, and the end face of short slot 8 is above lower limit screw 6.

When slide block 2 upwards slides; If touching 5 slide blocks 2 of upper limit screw, step surface 7 can't continue upwards to slide; When slide block 2 during to lower slider; Can't continue if the end face of short slot 8 touches 6 slide blocks 2 of lower limit screw, thereby the motion that guarantees density depressing cam 4 can not surpass the scope of setting, make the spacing of density depressing cam 4 and density rise cam 3 keep normal to lower slider.

Claims

1. the hosiery machine density regulating apparatus comprises body, slide block, density triangular, and density triangular comprises density depressing cam and density rise cam; The density depressing cam is fixed on the slide block; The density rise cam is fixed on the body, and slide block can slide up and down in body, it is characterized in that: also comprise upper limit screw and lower limit screw; Upper limit screw and lower limit screw all are fixed on the body; Some is positioned at the below of upper limit screw slide block, and some is positioned at the top of lower limit screw, and all has overlapping with two projections of stop screw on horizontal plane.
