[0017] The present invention will be further described below in conjunction with the accompanying drawings.

[0018] As attached Figure 1 and attached Figure 2 As shown, an automatic copper strip cleaning device based on thermal contact of the strip surface comprises a cleaning container 1, in which the copper strip 4 passing through the cleaning container 1 is immersed in the cleaning liquid for transportation; comprises a hot roller 2 and a reciprocating brush 3 located in the cleaning container 1; a plurality of the hot rollers 2 are arranged side by side along the conveying direction of the copper strip 4, and the copper strip 4 is conveyed in turn around a plurality of hot rollers 2 in a curve shape with crests and troughs, so that the roller surface of the hot roller 2 is in thermal contact with the strip surface of the copper strip 4; the reciprocating brush 3 corresponds to the hot roller 2 one by one, and the two cooperate to clamp the copper strip 4 passing through, and the reciprocating brush 3 is arranged parallel to the axis of the hot roller 2 in the reciprocating motion direction, so that the reciprocating brush 3 reciprocates in a direction perpendicular to the conveying direction of the copper strip 4 to wash the strip surface. The present invention achieves thermal contact between the hot roller 2 and the copper belt 4 and utilizes a reciprocating brush to reciprocate in a direction perpendicular to the conveying direction to wash the belt surface, thereby quickly loosening or dissolving dirt nodes on the belt surface and making it easier to be washed and removed. When the copper belt 4 is wrapped around the hot roller 2, the belt surface contacts the roller surface, thereby transferring the heat of the hot roller 2 to the copper belt 4. This is direct contact heat transfer without an intermediate medium, thereby quickly loosening or dissolving dirt nodes on the belt surface. Not only can the belt surfaces on both sides achieve thermal contact, but the contact area between the roller surface and the belt surface is relatively large, and heat conduction is more guaranteed. The reciprocating motion of the reciprocating brush 3 can wash and remove dirt on the belt surface. The direction of the reciprocating motion is perpendicular to the conveying direction of the copper belt 4, which has the effect of brushing off dirt more easily and quickly, thereby improving the cleaning efficiency and cleanliness of the copper belt 4 as a whole.

[0019] Since the heat roller 2 can rotate, its electrical connection must provide power to generate heat while taking into account the rotation action. Figure 2 As shown, the present invention includes a rotary contact type electrical connector 5; Figure 4 As shown, the hot roller 2 is rotatably connected to the cleaning container 1; a heating body 20 is arranged in the roller body of the hot roller 2, and the conductor 22 led out from the heating body 20 axially passes through the roller shaft and extends to the axial end of the roller body, and the conductor 22 is connected to the power supply through the rotating contact type electrical connector 5 installed on the cleaning container 1. The heating body 20 is a heating resistor, and the heating body 20 is distributed in a circumferential array in the roller body. More specifically, as shown in the attached Figure 3As shown, the rotary contact type electrical connector 5 includes a rotary electrical contact 51 and a feed type electrical contact 53 corresponding to the axial direction of the heat roller 2; the rotary electrical contact 51 connected to the conductor 22 is rotatably matched and arranged on the corresponding fixed contact seat 50, specifically, the fixed contact seat 50 is provided with an insulating bearing 54, and the rotary electrical contact 51 is rotatably connected to the fixed contact seat 50 through the insulating bearing 54, and the fixed contact seat 50 is fixedly mounted on the cleaning container 1; the feed type electrical contact 53 connected to the power supply is fixedly mounted on the corresponding elastic movable contact seat, and the feed type electrical contact 53 is elastically arranged on the fixed contact seat 50 through the elastic movable contact seat, so that the feed type electrical contact 53 maintains a state of elastic electrical contact with the rotary electrical contact 51 through elastic force, so that the electrical connection of the heat roller 2 can generate heat while taking into account the rotation action, thereby ensuring the rationality of the structure and the feasibility of functional perfection.

[0021] Since the rotating electric contact 51 rotates along with the hot roller 2, friction loss will be generated between it and the feeding electric contact 53. In order to reduce such friction, in the contact surface where the feeding electric contact 53 and the rotating electric contact 51 are in contact with each other, the contact surface of the feeding electric contact 53 is a planar structure, and the contact surface of the rotating electric contact 51 is a dome surface structure.

[0022] The roller shaft of the heat roller 2 has a conductor cavity corresponding to the conductor 22. The conductor 22 is arranged in the conductor cavity and forms an insulating protection gap between the cavity wall. The insulating protection gap is filled with an insulating layer to insulate the conductor 22 from the roller shaft.

[0023] In order to prevent the copper belt 4 from being tilted from the hot roller 2 by the reciprocating brush 3, it is necessary to limit the copper belt 4 in the width direction to ensure that it is in a good conveying posture without tilting.

The present invention includes a reciprocating drive mechanism 6 corresponding to the reciprocating brush 3; the reciprocating brush 3 is movably sealed with the wall of the cleaning container 1 through the push-pull shaft 30 at the reciprocating motion direction end thereof, and the reciprocating drive mechanism 6 drives the push-pull shaft 30 to drive the reciprocating brush 3 to reciprocate.

[0025] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
