Description

Yarn guide roller tensioning structure and doubling machine

Technical Field

The utility model belongs to the technical field of the weaving and specifically relates to a guide roll tensioning texture and doubling machine are related to.

Background

The guide rollers of a doubling machine tend to loosen after a long time of use, which results in too much fluffiness/tightness when introducing the yarn, thereby affecting the quality of the subsequently doubled yarn.

SUMMERY OF THE UTILITY MODEL

The utility model discloses a solve present yarn guide roll and produce the problem that influences the elasticity of yarn easily after long-time the use, for this reason provide a yarn guide roll tensioning texture, including yarn guide roll body and roller, still include the regulating plate, seted up a fore-and-aft slot hole on the regulating plate, even there is a threaded rod behind the rear end of roller passes yarn guide roll body, and still be equipped with back spacing lug in the junction of roller and threaded rod, the threaded rod passes behind the slot hole and nut threaded connection. Through loosening the nut, can make the threaded rod remove in order to realize the regulation of yarn tensioning in the slot hole, remove the back that targets in place, it can be with the fixed position of thread guide roller to tighten the nut again. And because the rear limiting convex block and the nut are respectively positioned at two sides of the adjusting plate, when the nut is screwed up, the adjusting plate can be clamped by the rear limiting convex block at the front side and the nut at the rear side, and the yarn guide roller body can be effectively ensured not to be inclined downwards due to gravity to influence the tensioning of yarns after being used for a long time. Even if the yarn guide roller body is deformed in a downward inclined manner, the tensioning can be ensured by loosening the nut, moving the threaded rod to a proper position and locking.

Preferably, the front end of the roll shaft is provided with a front limiting lug after penetrating through the yarn guide roll body, and the front limiting lug and the rear limiting lug can limit the yarn guide roll body to avoid loosening and falling after long-time use.

Preferably, the diameters of the rear limiting lug and the nut are larger than the width of the long hole, so that the adjusting plate can be firmly clamped.

Preferably, a bearing is further provided between the yarn guide roller body and the roller shaft in order to smoothly rotate the yarn guide roller body.

The utility model also provides a doubling frame, it includes above-mentioned thread guiding roller straining structure.

The utility model has the advantages that:

the utility model discloses a nut and back spacing lug can make the difficult slope of yarn guide roller body, even take place to incline, also can adjust the position of yarn guide roller body through the cooperation of slot hole on nut, screw rod and the regulating plate to there is suitable tensioning when guaranteeing to lead yarn.

Drawings

The invention will be described by way of example and with reference to the accompanying drawings, in which:

FIG. 1 is a perspective view of the front portion of the present invention;

fig. 2 is a perspective view of the rear part of the present invention;

fig. 3 is a partial sectional view of the present invention.

Detailed Description

The present invention will now be described in further detail with reference to the accompanying drawings. The drawings are simplified schematic drawings, which illustrate the basic structure of the present invention in a schematic manner, and thus show only the components related to the present invention.

In the description of the present invention, it should be noted that the terms "upper", "lower", "inner", "outer", "front end", "rear end", "both ends", "one end", "the other end", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention.

In the description of the present invention, it should be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "provided," "connected," and the like are to be construed broadly, such as "connected," which may be fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; the two components can be directly connected or indirectly connected through an intermediate medium, and the two components can be communicated with each other; the fixed connection can be welding or gluing. The specific meaning of the above terms in the present invention can be understood according to specific situations by those skilled in the art.

Example 1

The yarn guide roller tensioning structure shown in the figures 1-3 comprises a yarn guide roller body 1, a roller shaft 2 and an adjusting plate 4, a bearing is arranged between the yarn guide roller body 1 and the roller shaft 2, a longitudinal long hole 5 is formed in the adjusting plate 4, a front limiting lug 8 is arranged at the front end of the roller shaft 2 after the front end of the roller shaft passes through the yarn guide roller body 1, a threaded rod 3 is connected to the rear end of the roller shaft 2 after the rear end of the roller shaft passes through the yarn guide roller body 1, a rear limiting lug 7 is arranged at the joint of the roller shaft 2 and the threaded rod 3, and the front limiting lug and the rear limiting lug can limit the yarn guide roller body to avoid loosening and falling after long-time use. The threaded rod 3 penetrates through the long hole 5 and then is in threaded connection with the nut 6. The diameters of the rear limiting convex block 7 and the nut 6 are both larger than the width of the long hole 5. Through loosening the nut, can make the threaded rod remove in order to realize the regulation of yarn tensioning in the slot hole, remove the back that targets in place, it can be with the fixed position of thread guide roller to tighten the nut again. And because the rear limiting convex block and the nut are respectively positioned at two sides of the adjusting plate, when the nut is screwed up, the adjusting plate can be clamped by the rear limiting convex block at the front side and the nut at the rear side, and the yarn guide roller body can be effectively ensured not to be inclined downwards due to gravity to influence the tensioning of yarns after being used for a long time. Even if the yarn guide roller body is deformed in a downward inclined manner, the tensioning can be ensured by loosening the nut, moving the threaded rod to a proper position and locking.

Example 2

This embodiment is a doubling machine including the guide roller tensioning structure described in embodiment 1.

In light of the above, the present invention is not limited to the above embodiments, and various changes and modifications can be made by the worker without departing from the scope of the present invention. The technical scope of the present invention is not limited to the content of the description, and must be determined according to the scope of the claims.
