detailed description

The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

Referring to the multi-stage roller copper strip degreasing device shown in Figure 1, it is used to degrease the copper strip products obtained from the finishing mill, and can be installed at the exit of the finishing mill to directly perform online degreasing treatment on the copper strip.

The degreasing device includes a base 1 , a first degreasing assembly 2 and a second degreasing assembly 3 arranged along the front and rear directions of the base 1 .

The first degreasing assembly 2 includes a lower degreasing roller 21 arranged on the base 1, an upper degreasing roller 22 which can be lifted up and down on the base 1, and is used to drive the upper degreasing roller 22 up and down to remove the oil relative to the lower degreasing roller. The first driving device 23 for the movement of the oil roller 21 may be a hydraulic cylinder. The length extension direction of the last degreasing roller 23 and the following degreasing roller 22 is consistent with the width direction of the copper strip, and the upper degreasing roller 22 cooperates with the following degreasing roller 21 and is extruded on the upper and lower surfaces of the copper strip respectively to The copper strip is degreased.

The second degreasing assembly 3 includes a lower support base 31 that can be elastically moved up and down on the base 1, a first degreasing roller 32 that is located on the lower support base 31, and a roller that can be lifted up and down on the base 1. The second degreasing roller 34, is used to drive the second degreasing roller 34 lifting to move relative to the second driving device 35 of the first degreasing roller 32, here, the second degreasing roller 34 is installed on the upper supporting seat 33 and Driven by the second driving device 35, the second driving device 35 may be a hydraulic cylinder.

Between the bottom of the lower support seat 31 and the base 1, a plurality of elastic parts that can provide elastic restoring force in the up and down direction are provided. Here, what the elastic parts adopt is a spring 37, so that the lower support seat 31 and the first divider The oil roller 34 as a whole lifts elastically in the vertical direction, so that the first oil removal roller 32 cooperates with the second oil removal roller 34 and squeezes on the upper and lower surfaces of the copper strip to realize the degreasing treatment of the copper strip. Damage to the surface of the copper strip caused by excessive extrusion force can be avoided. Here, two support rollers 36 are also provided on the lower support base 31, and the first degreasing roller 36 is supported above the two support rollers 36 rollingly, and there is a gap between the two support rollers 36 along the front-rear direction. In this way, the oil after degreasing the copper strip through the cooperation of the first degreasing roller 32 and the second degreasing roller 34 will flow out through the gap.

When setting, the diameter of the upper degreasing roller 22 and the lower degreasing roller 21 in the first degreasing assembly 2 is greater than the diameter of the first degreasing roller 32 and the second degreasing roller 34 in the second degreasing assembly 3. In this embodiment, the former is twice as much as the latter. In this way, most of the rolling oil can be removed when the copper strip is deoiled by the first deoiling assembly 2 , and then removed by the second deoiling assembly 3 . In addition, when the copper strip passes through the first degreasing assembly 2 and the second degreasing assembly 3, it is preferable to extend along the same straight line.

Referring to Fig. 1, the degreasing device also includes a purge nozzle assembly 4 arranged behind the second degreasing assembly 3, the purge nozzle assembly 4 includes an upper purge nozzle 41 and a lower purge nozzle 42, the upper purge nozzle The nozzle 41 is fixedly installed on the upper support seat 33 and is located above the copper strip, and is aligned with the position where the second degreasing roller 34 contacts the copper strip; the lower purge nozzle 42 is fixedly installed on the lower support seat 31 and is located on the copper strip. below, which is aligned with the position where the first degreasing roller 32 is in contact with the copper strip. This further purges away residual oil on the copper strip surface.

Referring to shown in Fig. 1, this degreasing device also comprises the mobile nozzle assembly that is located at the rear of the second degreasing assembly 3, and this mobile nozzle assembly comprises a plurality of mobile purge nozzles 5 that can move along the width direction of copper strip, and this mobile The purge nozzle 5 is aimed at the upper surface or the lower surface of the copper strip after degreasing treatment by the second degreasing assembly 3 and the purge nozzle assembly 4, so as to realize further degreasing.

Before the degreasing process, the heights of the upper degreasing roller 22 and the second degreasing roller 34 are adjusted respectively by the first driving device 23 and the second driving device 35, so that the height between the upper degreasing roller 22 and the lower degreasing roller 21 The spacing between the first degreasing roller 32 and the second degreasing roller 34 can allow the copper strip to fit through. The copper strip obtained by the rolling production of the finishing mill is first degreased through the extrusion of the lower degreasing roller 21 and the upper degreasing roller 22 of the first degreasing assembly 2, and this step can remove most of the rolled copper strip. Oil removal; the copper strip continues to be sent to the second oil removal assembly 3, and the second oil removal is realized through the elastic extrusion of the first oil removal roller 32 and the second oil removal roller 34, and the blowing nozzle assembly 4 works simultaneously. The movement of the oil on the surface of the copper strip is accelerated to improve the effect of the secondary degreasing; the copper strip after the secondary degreasing is then purged through a plurality of mobile purge nozzles 5 for further degreasing, further improving the degreasing efficiency Effect.

To sum up, the degreasing device of the present invention has a simple structure, can make the copper strip obtain a good degreasing effect, and can ensure that the surface of the copper strip is not damaged during the degreasing process, and obtain a good standard quality, and the production cost is low , Excellent degreasing effect.
