Description

The air bag roll

[technical field]

The utility model relates to a kind of rubber roller, particularly a kind of air bag roll.

[background technology]

Rubber roller is widely used in various dyeing machines, effect such as play conveying, clamping, roll.When being used for destarch scouring machine and oxygen bleaching machine, rubber roller and fabric guide roll need be pressed on the positive and negative surface of fabric mutually, make fabric have certain reaction liquid, float effect to guarantee destarch, oxygen.If rubber roller and selvage guide roll gap pressure are excessive, rubber layer deformation is near the limit, and the reactant liquor between fabric fibre is extruded in a large number, and then the webbing liquid measure is not enough, and destarch, oxygen float reaction not exclusively; If the too small then webbing of pressure liquid measure is inhomogeneous, local fabric desizing, that oxygen floats response difference is big.Fabric all can not reach good destarch under the above-mentioned situation, oxygen floats effect, makes that wool effect of the fabric is low, feel is poor, directly influences dye-uptake, the level-dyeing property of fabric, and finished product coloured light withers secretly, so the pressure between the control roll body becomes the important step of technology.Existing rubber roller, for the roll body surface is coated with rubber layer, two ends are connected with solid spindle nose, and destarch, oxygen bleaching process change pressure between rubber roller and the fabric guide roll by the elasticity of the position that changes roll body and rubber layer, thereby guarantee that the reactant liquor between fabric fibre is evenly an amount of.Because rubber layer deformation amplitude is limited, deformation is inhomogeneous and rely on the high and low position realization adjusting of change rubber roller and the moderate pressure operation inconvenience between fabric guide roll, the degree of accuracy is wayward, influences the quality of fabric.

[utility model content]

The technical assignment of the technical problems to be solved in the utility model and proposition is to overcome the defective that existing rubber roller exists, provide a kind of self elasticity amplitude big, deformation is even, does not change the air bag roll that pressure between rubber roller and the fabric guide roll just can be adjusted in the roll body position.

For this reason, the utility model adopts following technical scheme:

The air bag roll, comprise dough deformation layer, the spindle nose that is positioned at the roll body two ends that hollow roll body, roll body outer surface cover, be placed on spindle nose and be connected the capping at roll body two ends, it is characterized in that having pore on the hollow roll body, the outer end of one spindle nose is provided with the gas joint, the centre is provided with the communicating pipe that links to each other with the gas joint, and the inner socket periphery of described two spindle noses has the end cap of through hole.The hollow roll body is the rigidity roll body, and it can guarantee the intensity of air bag roller, and the pore on it helps the air pressure stepless action in the dough deformation layer.The space that capping, spindle nose, roll body and dough deformation layer surround forms sealed gas chamber, one spindle nose is provided with gas joint and communicating pipe, can be to air chamber inflation pressurization, gas can be dispersed in roll body inside by the through hole on the end cap, and evenly exert pressure for its outer dough deformation layer that covers by the pore on the roll body, realize changing the flexible purpose of air bag roll by changing gas pressure.Even do not change the hollow roller body position, also can make pressure fine setting between air bag roll and the fabric guide roll to evenly moderate, satisfy destarch, kiering, oxygen and float evenly an amount of requirement of webbing liquid in the operation.

Described dough deformation layer is a rubber layer, and this layer two ends are nested with the anchor ear that is fixed on the roll body.This not only can be affixed the two, also help airtight between roll body two ends and the rubber layer.

Described spindle nose outer end is provided with annular boss, and capping is connected with boss.Boss is set increases the contact area of capping and spindle nose, and it is fixedly connected to be convenient to both, helps the airtight of air chamber.

Described spindle nose the inner is provided with annular recessed portion, and end cap is connected with recess.Recess is set increases the contact area of end cap and spindle nose, is convenient to end cap is fixed on the spindle nose.

Described capping and boss, roll body seal welding; End cap and recess welding.The capping seal welding guarantees that air chamber is a confined space on spindle nose and roll body, be convenient to adjust the pressure in the air chamber, thereby increases the elasticity of air bag roll; End cap and recess welding, it is fixedly connected to be convenient to both, and end cap plays the effect of supporting the roll body middle part again to a certain extent simultaneously.

Of the present utility model by being adjusted at the deformation amplitude that the gas pressure that forms sealed gas chamber in the roll body changes rubber layer, make its deformation even, under the situation that does not change the air bag roll location, adjust to the pressure between itself and the fabric guide roll moderate easily according to different fabrics, easy to operate, the degree of accuracy is easy to control, makes reactant liquor between fabric fibre uniform an amount of, and it is outstanding that destarch, kiering, oxygen float effect.

[specific embodiment]

Below in conjunction with specification drawings and specific embodiments substantive distinguishing features of the present utility model is further described.

As shown in Figure 1, roll body of the present utility model is a seamless steel pipe, and having the equally distributed diameter of intersection on it is about 12860 pores 9 of 6mm.Roll body, two spindle noses 4 and capping 3 form air chambers 11.The end that two spindle noses 4 are positioned at the roll body outside is provided with annular boss 2, capping 3 is an annular, its interior diameter is just satisfied to be placed on spindle nose and to be limited in boss 2, the end that seal welding between the two, two spindle noses 4 stretch in the roll body has annular recess 8, and end cap 6 be annular, its overall diameter is identical with the roll body inner diameter, interior diameter just satisfies the requirement that is placed on recess 8, and is welded in recess 8, evenly has some through holes 7 on the periphery of end cap 6; The overall diameter of capping 3 is identical with the roll body inner diameter, both seal weldings.A spindle nose 4 wherein, the axle center has communicating pipe 5, and the outside end of roll body is provided with gas joint 1, and communicating pipes 5, gentle joint 1 was communicated with, and extraneous gas can be by gas joint 1 and communicating pipe 5 entering into air chamber 11, and gas evenly divides in air chamber 11 by the through hole on the end cap 67.The roll body outside is coated with the rubber layer 10 that material is the nitrile rubber of anti-highly basic, anchor ear 12 closely is fixed on rubber layer 10 on the roll body, make air chamber 11 become sealed gas chamber, can be by replenishing or discharge the method for gas pressure in the gas and changing air chamber 11, make rubber layer extend out uniformly or shrink, reaching increases the flexible purpose of air bag roll, easily that the pressure between air bag roll and the fabric guide roll is fine-tuning to evenly moderate, satisfies destarch, kiering, oxygen and floats evenly an amount of requirement of webbing liquid in the operation.
