Description

Swelling device

Technical field

The utility model relates to a kind of swelling device, the stamper swelling device that especially a kind of textile industry is used.

Background technology

Traditional stamper that is wound with bus on tricot machine is all generally to be mounted on installation shaft, then unreel, by the yarn divider dividing sinker, the mode of this extension volume is the meeting radial-play in the stamper rotation process, and stamper is generally axially over against the sub-wire machine, so just cause the torsion phenomenon of female silk on stamper, affected sub-wire.

Summary of the invention

The purpose of this utility model is to provide the swelling device that a kind of tensioner is reliable, prevent the stamper end float misalignment.

In order to achieve the above object, the technical solution of the utility model is: a kind of swelling device, comprise tension shaft, sleeve pipe, the first back-up ring, the second back-up ring, spring coil, fastener and plural T shape tensioner sheet, one end of tension shaft is provided with radially backstop, the first back-up ring, sleeve pipe and the second back-up ring are sleeved on tension shaft successively, and an end of the first back-up ring offsets with backstop radially, one end of the other end and sleeve pipe offsets, the periphery of sleeve pipe is provided with the axial limiting groove more than two, plural tensioner sheet is contained in respectively on the axial limiting groove, the periphery of the first back-up ring and the second back-up ring is circular cone, the conical surface at tensioner sheet two ends offsets with the circular cone of the first back-up ring and the second back-up ring periphery respectively, and make the other end of sleeve pipe and an end of the second back-up ring there is gap S, spring coil is sleeved on sleeve pipe, and offset with plural tensioner sheet, fastener is threaded with the other end of tension shaft, and offset with the second back-up ring.

One end of described the second back-up ring is provided with annular protrusion, and the other end of sleeve pipe is provided with the circular pit coordinated with annular protrusion, and annular protrusion stretches in circular pit.

Described tensioner sheet has six, and sleeve pipe is provided with six axial limiting grooves.

Described tensioner sheet is provided with two positioning grooves, and spring coil has two, and spring coil is contained in positioning groove respectively.

Described fastener is hexagonal nut.

After adopting said structure, because the periphery of sleeve pipe is provided with the axial limiting groove more than two, plural tensioner sheet is contained in respectively on the axial limiting groove, the periphery of the first back-up ring and the second back-up ring is circular cone, the conical surface at tensioner sheet two ends offsets with the circular cone of the first back-up ring and the second back-up ring periphery respectively, and make the other end of sleeve pipe and an end of the second back-up ring there is gap S, spring coil is sleeved on sleeve pipe, and offset with plural tensioner sheet, fastener is threaded with the other end of tension shaft, and offset with the second back-up ring, therefore in the tensioner process, pass through tightening fastener parts, make the second back-up ring move to the sleeve pipe direction, because the first back-up ring and the second back-up ring and tensioner sheet are cone match, just can be by tensioner sheet radially outward swelling along sleeve pipe slowly, by the stamper tensioner, therefore tensioner is firm, prevent the radial-play of stamper, drive tension shaft by servomotor again, just can realize initiatively unreeling.

The accompanying drawing explanation

Fig. 1 is complete section figure of the present utility model;

Fig. 2 is the A-A cutaway view in Fig. 1.

The specific embodiment

The embodiment provided below in conjunction with accompanying drawing is described in further detail the utility model.

Referring to Fig. 1, shown in 2, a kind of swelling device, comprise tension shaft 1, sleeve pipe 2, the first back-up ring 3, the second back-up ring 4, spring coil 5, fastener 6 and plural T shape tensioner sheet 7, one end of tension shaft 1 is provided with radially backstop 1-1, the first back-up ring 3, sleeve pipe 2 and the second back-up ring 4 are sleeved on tension shaft 1 successively, and an end of the first back-up ring 3 offsets with backstop 1-1 radially, one end of the other end and sleeve pipe 2 offsets, the periphery of sleeve pipe 2 is provided with the axial limiting groove 2-1 more than two, plural tensioner sheet 7 is contained in respectively on axial limiting groove 2-1, the periphery of the first back-up ring 3 and the second back-up ring 4 is circular cone, the conical surface at tensioner sheet 7 two ends offsets with the circular cone of the first back-up ring 3 and the second back-up ring 4 peripheries respectively, and make the other end of sleeve pipe 2 and an end of the second back-up ring 4 there is gap S, spring coil 5 is sleeved on sleeve pipe 2, and offset with plural tensioner sheet 7, fastener 6 is threaded with the other end of tension shaft 1, and offset with the second back-up ring 4.

Shown in Figure 1, one end of described the second back-up ring 4 is provided with annular protrusion 4-1, the other end of sleeve pipe 2 is provided with the circular pit 2-2 coordinated with annular protrusion 4-1, annular protrusion 4-1 stretches in circular pit 2-2, like this in the tensioner process, the second back-up ring 4 just can be spacing in movement, can not radially wobble, and stuck phenomenon occurs.

Shown in Fig. 1,2, described tensioner sheet 7 has six, and sleeve pipe 2 is provided with six axial limiting groove 2-1, for better tensioner stamper.

Shown in Figure 1, described tensioner sheet 7 is provided with two positioning groove 7-1, and spring coil 5 has two, and spring coil 5 is contained in respectively in positioning groove 7-1, and the effect of spring coil 5 is to guarantee that tensioner sheet 7 can not drop.

Shown in Figure 1, described fastener 6 is hexagonal nut, and like this with regard to convenient disassembly, tensioner is also convenient.

Referring to Fig. 1, shown in 2, when the utility model is used, by the first back-up ring 3, sleeve pipe 2 and the second back-up ring 4 are sleeved on tension shaft 1 successively, then by fastener 6, with tension shaft 1, be threaded, tensioner sheet 7 is contained on the axial limiting groove 2-1 of sleeve pipe 2, and by spring coil 5 bandings, make tensioner sheet 7 can not drop, when the needs tensioner, as long as tighten firmware 6, make the second back-up ring 4 move to sleeve pipe 2 directions, because the first back-up ring 3 and the second back-up ring 4 are cone match with tensioner sheet 7, just can be by tensioner sheet 7 radially outward swelling along sleeve pipe 2 slowly, by the stamper tensioner, therefore tensioner is firm, prevent the radial-play of stamper, fill servomotor again on tension shaft 1, drive tension shaft 1 by servomotor, just can realize initiatively unreeling, and after employing the utility model, stamper does not need axis over against leaser, can axis and the leaser vertical direction install and get final product, not there will be the female silk torsion phenomenon on stamper, the sub-wire successful.
