Abstract
The utility model discloses a kind of constant speed wrap-up, including the preliminary roller and back roller rotate in same direction, for driving the wind-up roll being arranged between the preliminary roller and back roller to rotate.Gap between preliminary roller and back roller is less than the diameter of wind-up roll.Preliminary roller and the diameter of back roller are equal, and preliminary roller rotates linear velocity and is more than back roller rotation linear velocity.The utility model drives wind-up roll to rotate by rotating in same direction for front and rear roller, carries out the winding of fabric.Tension force is produced by the speed difference of front and rear roller to control the elasticity of winding.Ensure the elasticity of reel by fixed rotating ratio, keep the uniformity of product.
Description
Technical field
The utility model belongs to equipment for dyeing and finishing technical field, more particularly to a kind of constant speed wrap-up.
Background technology
Winder is indispensable equipment in fabric production process, its main function is to receive the fabric after the completion of manufacture
It is rolled into the structure of a tubular.Winding tension difference has large effect for the diameter of last tubular fabric.The tune of tension force
It is whole that certain difference is also had for different operating personnel, finished product as a result can be caused elastic inconsistent, influence product
Uniformity.
The content of the invention
The defects of the utility model aim is to be directed to existing constant speed wrap-up, there is provided one kind can ensure to wind elastic
The constant speed wrap-up of degree.
The utility model to achieve the above object, adopts the following technical scheme that：
A kind of constant speed wrap-up, including the preliminary roller and back roller rotate in same direction, the preliminary roller is arranged on after for driving
Wind-up roll between roller rotates, it is characterised in that：The rotation linear velocity of the preliminary roller and back roller is unequal.
It is further characterized by：The preliminary roller rotates linear velocity and is more than back roller rotation linear velocity.
Further：The preliminary roller rotates linear velocity, back roller rotates linear velocity fixed setting.
Preferably：It is 1.3 that the preliminary roller, which rotates linear velocity with back roller rotational line speed ratio,：1.
The preliminary roller and rear roller diameter are equal.
Gap between the preliminary roller and back roller is less than the diameter of the wind-up roll.
The beneficial effects of the utility model：
The utility model drives wind-up roll to rotate by rotating in same direction for front and rear roller, carries out the winding of fabric.By preceding
The speed difference of back roller produces tension force to control the elasticity of winding.Ensure the elasticity of reel by fixed rotating ratio, protect
Hold the uniformity of product.
Brief description of the drawings
Fig. 1 is utility model diagram.
Embodiment
A kind of constant speed wrap-up as shown in Figure 1, including the preliminary roller 1 and back roller 2 rotate in same direction, institute is arranged on for driving
The wind-up roll 3 stated between preliminary roller 1 and back roller 2 rotates.Gap between preliminary roller 1 and back roller 2 is less than the diameter of wind-up roll 3.Preliminary roller 1
Equal with the diameter of back roller 2, preliminary roller 1 rotates linear velocity and is more than the rotation linear velocity of back roller 2.
Preferably：1 rotating speed of preliminary roller is 1.3 in 2 rotating speed rotating ratio of back roller：1.
During utility model works, drive wind-up roll 3 to rotate by rotating in same direction for front and rear roller, carry out the receipts of fabric 4
Volume.Tension force is produced by the speed difference of front and rear roller to control the elasticity of winding.Reel is ensured by fixed rotating ratio
Elasticity, keeps the uniformity of product.
