Abstract

The utility model relates to a metal underlay rubber roller of a spinning middleupper roller, which is used in a drawing apparatus of a spinning machine and belongs to the technical field of parts of the spinning machine. The utility model stabilizes the rotation of spinning aprons, effectively controlling the motion state of the yarn fibre. Mainly, the rubber material is coated around the outer layer of a metal liner. The inner diameter of the metal liner is 18-21mm, and the wall thickness is 0.8-1.2mm. The thickness of the rubber material is 2-5mm. The utility model has the advantages of simple, compact and reasonable structure, rust resistance under the condition of high temperature and high humidity, guarantee of the stable running of sprinning aprons, enlarged coating of spinning aprons on the yarn fibre strand, increased gripping performance, effective reduction of frequent yarn faults and increased yarn quality.

Description

The metal liner rubber rollers of spinning middle top roller

Technical field:

The utility model relates to a kind of metal liner rubber rollers of the middle top roller that spins, and is used for drafting device for spinning machine, makes the stable revolution of spinning apron, effectively controls the motion state of yarn fiber, belongs to the workshops accessory technical field.

Background technology:

The core component of drafting device for spinning machine by before, during and after three pairs of upper and lower rollers form.Before the utility model was made, in prior art, middle top roller was a bearing work heart iron roll, is combined into one with last pin, last cushion rubber, and middle bottom roller is an annular knurl shape roller, is combined into one with downside pin, following cushion rubber.Cushion rubber plane contact up and down, bottom roll is an active body, top roller is pressurization.Draw zone before and after upper and lower middle roller and forward and backward, upper and lower roller are formed respectively carries out drawing-off to fiber strip.During spinning, fiber strip passes through between upper and lower cushion rubber, the process middle top roller is to the pressurization of cushion rubber and the friction of cushion rubber, fiber strip is produced grasping force, form different drafting multiples, make that fibre weight reduces gradually in the yarn yarn at forward and backward draw zone, while controlling fiber motion speed change point, form speed difference, hooked fibre is stretched, roving-drafting is the spun yarn with certain mass state the most at last.The stability of middle top roller running, rotating steadily to cushion rubber, resultant yarn often the property sent out yarn defect how many significant effects arranged.

The heart iron roll alive of middle top roller in use has the following disadvantages:

1. the heart iron roll hardness height alive of metal, the cushion rubber thin thickness that is attached to the iron roll apparent motion only has 0.9-1.0mm.The elasticity of rubber bodies is relevant with thickness, and thin thickness then flexibility decrease is low.Cushion rubber is little to the coating face that yarn spins bar, and is little with the frictional contact surface of fiber, and a little less than the gripping control just to fiber, often the property sent out yarn defect rises, and influences the quality of resultant yarn.

2. the workshop moisture temperature height spins, throughout the year general temperature is about 30 degree, relative humidity reaches 55-60%, the heart iron roll of living easily gets rusty under hot and humid condition, and rust staining protrudes iron roll surface and very coarse again, makes the cushion rubber revolution dumb, pressure between cushion rubber running speed and the last bottom roll, the generating period fluctuation causes into the dried mechanical wave of sliver, and quality is reduced.

Summary of the invention:

The purpose of this utility model is to overcome above-mentioned weak point, thereby provides a kind of simple, compact and reasonable for structure; At high temperature non-corrosive under the super-humid conditions can make the spinning apron running steadily, can enlarge the coating of cushion rubber to the yarn yarn, can effectively control the motion of fiber in the yarn yarn, and can reduce the metal liner rubber rollers of the spinning middle top roller of the normal property sent out yarn defect.

Main solution of the present utility model is achieved in that

It is mainly by metal liner 1, and rubber bodies 2 is formed.At metal liner 1 outer rubber-coated body 2.

Compared with the prior art the utility model has the following advantages:

The utility model is simple, compact and reasonable for structure; Non-corrosive under hot and humid condition can make the spinning apron running steadily, can enlarge the coating of cushion rubber to the yarn yarn; Can improve the gripping performance, can effectively reduce the normal property yarn defect of sending out, improve yarn quality, under different condition, the yarn quality level can improve 2-8%.

Description of drawings:

Fig. 1 is the utility model structural front view;

The specific embodiment:

Embodiment during following the utility model is incited somebody to action in conjunction with the accompanying drawings is further described:

The utility model middle top roller metal liner rubber rollers is formed by two layers, and internal layer adopts the metal tube 1 with certain ductility, and its tube wall internal diameter is 18-21mm, and pipe thickness is 0.8-1.2mm.At the outer rubber-coated body 2 of metal tube 1 tube wall.Rubber bodies thickness is pressed spun yarn, and the requirement of rove different process generally is controlled at 2-5mm, and rubber hardness can be according to using needs to select Shao Shi A80-98 degree, and its width can need decision by the difference type that spins.Rubber bodies has antistatic behaviour, prevents to adhere to colorful clothes.Rubber surface tempers, and is bright and clean smooth, packs on front upper roller, use as middle top roller,

The utility model middle top roller metal liner rubber rollers in use, should select standard compliant upper roller bearing, adopt vertical cover roller machine, the last item of cover roller machine during the cover system, the metal liner rubber rollers, it is vertical with one heart that the upper roller bearing three must keep, casing pressure puts in place successively, on the rubber roll grinding machine, finish grind external diameter then, outside dimension control: be used for spun yarn 25-25.1mm, being used for rove is 29-29.1mm, with two top roller diameter difference＜0.02mm of shelves, metal liner rubber rollers surface should be bright and clean smooth, and with conventional rubber roll surface conditioning agent A: B=1: 2-5 handles once, also can not carry out surface treatment.

Claims

1. the metal liner rubber rollers of the middle top roller that spins is characterized in that at the outer rubber-coated body of metal liner (1) (2).

2, the metal liner rubber rollers of a kind of middle top roller that spins according to claim 1 is characterized in that described metal tube (1) tube wall internal diameter is 18-21mm, and pipe thickness is 0.8-1.2mm.。
