Description

Negative pressure process piece of three-primary color compact spinning T-shaped symmetrical groove of ring spinning frame

Technical Field

The utility model belongs to ring spinning frame field, concretely relates to ring spinning frame three primary colors compact spins T shape symmetrical groove negative pressure technology piece.

Background

With the development of textile industry, the three-primary-color compact spinning technology of the existing ring spinning frame uses a single-yarn compact spinning single-chute negative-pressure process piece 8 (as shown in fig. 5) due to the previous recognition deficiency, and the negative-pressure process piece is found in the actual spinning process and is only suitable for the situation of spinning spun yarns by single roving, the single roving is not related to the arrangement problem of fibers in a drafting zone, and an inclination angle is formed between the compact trough and a vertical line, so that the fibers move forward under the driving of a grid ring and air negative pressure and have the action of overturning, and the purpose is to enable the fibers to be well compacted. The siro-spun double-chute negative pressure process piece 6 (shown in figure 5) used for siro spinning can solve the problem of arrangement of two pieces of rough yarn, but cannot be applied to ternary spinning. However, when the three-way color spinning is performed, three rovings with different colors are arranged at different positions in the left, middle and right directions through overturning or left and right jumping, so that the colors of the coupled spun yarns are different, the phenomena of overturning and left and right jumping cannot occur when the roving fiber passes through the gathering area, the colors of the spun yarns in all spindle positions are ensured to be consistent, and the arrangement sequence of the three rovings in all spindle positions cannot be changed irregularly when the three rovings in all spindle positions pass through the drafting area.

Disclosure of Invention

The to-be-solved technical problem of the utility model is to provide a ternary color gathers spins T shape symmetric groove negative pressure technology piece, guarantees three roving fiber according to the order of arranging of the preset left side of spinning technology in the right side from mechanical structure, reachs through the draft district and gathers and spins the district after, when gathering, three roving fiber's the left side in the right side order of arranging can not produce the state of irregular change and influence the spun yarn, avoids appearing the unstable problem of spun yarn colour.

Moreover, the three thick yarns are gathered together under the action of the negative air pressure, so that the style of the spun yarn is unique.

The utility model adopts the technical proposal that: a negative pressure process piece of a T-shaped symmetrical groove for triple color compact spinning of a ring spinning frame comprises a main body in an arc sheet structure, an upper clamping strip is arranged on the upper edge of the main body, a lower clamping strip is arranged on the lower edge of the main body, and a compact negative pressure groove in a T-shaped symmetrical structure is formed in the radial direction of the main body.

The ring spinning frame three-color compact spinning T-shaped symmetrical groove negative pressure process piece is clamped with a compact spinning special-shaped pipe of a compact spinning device through an upper clamping strip and a lower clamping strip respectively, so that the ring spinning frame three-color compact spinning T-shaped symmetrical groove negative pressure process piece is fixed on the compact spinning device, the head end and the notch of the compact spinning negative pressure groove are in streamline closing smooth transition, and the compact spinning negative pressure groove is arranged in the middle of the main body.

Furthermore, the ring spinning frame three-primary color compact spinning T-shaped symmetrical groove negative pressure process piece is made of stainless steel with good wear resistance and small friction coefficient with the grid ring.

Compared with the prior art, the utility model its beneficial effect is: the utility model provides a ring spinning frame ternary gathers spins T shape symmetrical groove negative pressure technology piece, on the basis that does not change current ring spinning and joins in marriage to gather and spin the technique, does not need redesign to gather spins the negative pressure mechanical tubes, when assembling for ternary ring spinning frame and gather and spin, only need with "ternary gather spins T shape symmetrical groove negative pressure technology piece" replace "single yarn and gather spins single chute negative pressure technology piece" can. The assembly method and the assembly tool do not need to be replaced, and the very simple improvement ensures that the left, middle and right arrangement sequence of the roving is consistent when the compact spinning technology is used in the ternary spinning, thereby realizing correct spinning. When the three-component color spinning is carried out, three types of roving fibers enter the gathering region after being drafted in the back region and the front region, and correct spinning of a ring spinning frame with a three-channel back roller can be realized while effective gathering is carried out. Each spindle corresponds to one process sheet, and the device is simple in structure, convenient to install and low in cost. The arrangement sequence of all spindle rough yarns is ensured to be consistent mainly from the shape of the negative pressure notch, the wrapping sequence of fiber batting strips in a twisting triangular area in front of the aggregation spinning roller is the same, and the appearance quality of spun yarns is consistent.
