Description

Technical Field

[0001] The invention relates to the technical field of cleaning, and in particular to a device for cleaning the surface of a wire without pickling and a method for using the device. Background Art

[0002] Generally, there is an oxide layer on the surface of the raw metal wire of welding wire. Rust on the surface of the wire will cause wire loss, and the wire with rust on the surface cannot be used directly. In the process of processing the raw material into welding wire, due to the oxide layer on the surface of the raw material, and due to storage and transportation reasons, the surface of the raw material may be rusted, oily and other defects, which require surface cleaning.

[0003] The original process of removing oxide scale in the industry mainly uses chemical methods, including sulfuric acid, hydrochloric acid, hydrofluoric acid, nitric acid and other acidic reagents. Generally, two processes are adopted: centralized whole-piece acid treatment and online automatic electrolytic acid treatment. Regardless of which process is used, acid mist will pollute the air and endanger the health of workers when the material surface is treated. A large amount of clean water is needed for subsequent cleaning, which will produce a large amount of acid-containing wastewater. After one stage of use, the acid solution needs to be scrapped and updated. The waste acid produced contains a large amount of iron salts and sludge. The waste acid needs to be treated by a qualified environmental protection department, and the overall environmental protection cost is very high. Therefore, a surface oxide layer cleaning method that has no impact on the environment is needed.

[0004] At present, some industries are developing a process to use a sanding machine to remove the oxide scale on wires. This process uses two sets of sanding belts to rotate at high speed to grind the oxide scale on the surface of the wire. When the sanding machine is grinding, the sanding belt is a consumable part. Rapid friction leads to a short service life, especially on rainy days. Due to high humidity in the air, the sanding belt paper and wire are damp, the sanding belt is more prone to wear and tear, and the service life is reduced. Due to wear and tear, the sanding belt needs to be replaced frequently, resulting in reduced work efficiency. When replacing the sanding belt, the sanding belt tension needs to be adjusted. Loose tension cannot achieve the required effect, and high tension can easily wear the machine's own parts. The sanding machine only has two sets of sanding belts rotating. When the wire is pulled in, there will be parts that cannot be rubbed during rotation and movement, and there will be residual oxide layers that are not completely removed, thus affecting subsequent production operations. Summary of the invention

[0005] The technical problem to be solved by the present invention is: in order to solve the problem of using a sanding belt machine to remove wire oxide scale in some industries, the process uses two sets of sanding belts to rotate at high speed to grind the oxide scale on the surface of the wire. When the sanding belt machine is grinding, the sanding belt is a consumable part, and the rapid friction leads to a short service life, especially on rainy days, due to the high humidity in the air, the sanding belt paper and the wire are damp, the sanding belt is more prone to wear and tear, and the service life is reduced. Due to wear and tear, the sanding belt needs to be replaced frequently, resulting in reduced work efficiency. When replacing the sanding belt, the tension of the sanding belt needs to be adjusted. Loose tension cannot achieve the required effect, and high tension is easy to wear the parts of the machine itself. The sanding belt machine has only two sets of sanding belts rotating. When the wire is pulled in, there will be parts that cannot be rubbed during rotation and movement, and there will be residual oxide layers that are not completely removed, thus affecting subsequent production operations. A non-acid-washing wire surface rust removal and cleaning device is now provided.

[0006] The technical solution adopted by the present invention to solve the technical problem is: a non-pickling wire surface rust removal and cleaning device, comprising a shelling mechanism arranged on a frame for twisting the wire, the shelling mechanism comprising a first guide wheel group and a second guide wheel group rotatably arranged on the frame, the first guide wheel group comprising a plurality of first guide wheels rotatably arranged on the frame, the plurality of first guide wheels being arranged parallel to each other, the second guide wheel group comprising a plurality of second guide wheels rotatably arranged on the frame, the plurality of second guide wheels being arranged parallel to each other, the central axis of the first guide wheel and the central axis of the second guide wheel being arranged staggered with each other, and a descaling mechanism for rust removal and cleaning of the twisted wire is arranged on one side of the shelling mechanism on the frame. The wire is twisted in two directions in one plane by the first guide wheel group, and then twisted in two directions in one plane by the second guide wheel group. Since the central axis of the first guide wheel and the central axis of the second guide wheel are staggered with each other, that is, the plane where the wire is twisted in the first guide wheel group and the plane where the wire is twisted in the second guide wheel group are staggered with each other, the wire is twisted in four directions, so that the oxide layer on the surface of the wire is loosened for shelling.

[0007] In order to be able to descale the wire, the descaling mechanism further includes a connecting rod, a tension spring and a rotating shaft. The rotating shaft is rotatably set on the frame, one end of the connecting rod is rotatably set and hinged on the frame, and the other end of the connecting rod is provided with a cleaning head for descaling the wire. One end of the tension spring is set on the connecting rod, and the other end of the pull rod is set on the rotating shaft. The conveying direction of the wire, the central axis of the rotating shaft and the rotation center axis of the connecting rod are arranged parallel to each other, and a limiting mechanism for limiting the rotation of the rotating shaft is provided on the frame.

[0008] In order to prevent the rotating shaft from rotating, the limiting mechanism further comprises a ratchet wheel mounted on the rotating shaft, and a thorn is mounted on the frame, and the thorn is clamped in the tooth groove of the ratchet wheel. By mounting the ratchet wheel on the rotating shaft and cooperating with the thorn on the frame, the rotating shaft is prevented from rotating in the opposite direction, so that the rotating shaft can maintain a certain tension on the tension spring to prevent the tension spring from loosening.

[0009] In order to drive the rotating shaft to rotate, a motor is provided on the frame, and the motor is connected to the rotating shaft through a pulley. The motor and the rotating shaft are connected through a pulley, so that the rotating shaft can rotate on the frame.

[0010] In order to remove scale from the outer circumference of the wire, further, there are a plurality of descaling mechanisms, which are distributed around the circumference of the wire. The descaling mechanisms are distributed circumferentially on the frame, that is, the connecting rods of the descaling mechanisms on the frame are distributed along the circumference of the wire, so that the cleaning heads at one end of the connecting rods surround the wire.

[0011] In order to facilitate the maintenance of the cleaning head, further, one end of the connecting rod is provided with a groove for placing the cleaning head, one end of the cleaning head matches the groove, one end of the connecting rod is provided with a screw, a through hole connected to the groove is provided on the connecting rod, one end of the cleaning head is placed in the groove, and the screw passes through the through hole and is threadedly connected to the nut, thereby fixing the cleaning head on the connecting rod. In a detachable manner, the cleaning head can be quickly installed on the connecting rod, thereby facilitating the later maintenance of the cleaning head.

[0012] A method for using the above-mentioned non-acid-washing wire surface rust removal and cleaning device is characterized in that: the method for using is as follows:

[0013] First, after the wire is unwound, the wire enters between the first guide wheel and the second guide wheel for shelling. After the wire is shelled, the wire passes through the descaling mechanism behind the frame, and the cleaning head is controlled to descale and clean the surface of the wire, thereby completing the surface rust removal of the wire.

[0014] The beneficial effects of the present invention are as follows: when the pickling-free wire surface rust removal and cleaning device of the present invention is in use, the wire is twisted in two directions in one plane by the first guide wheel group, and then twisted in two directions in one plane by the second guide wheel group. Since the central axis of the first guide wheel and the central axis of the second guide wheel are staggered, that is, the plane in which the wire is twisted in the first guide wheel group and the plane in which the wire is twisted in the second guide wheel group are staggered, the wire is twisted in four directions, so that the oxide layer on the surface of the wire is loosened for peeling, avoiding the current process of using a sanding machine to remove the oxide skin of the wire developed by some industries, which uses two groups of sanding belts to rotate at high speed to grind the oxide skin on the surface of the wire. When the sanding machine is grinding, the sanding belt is a consumable part, and the rapid friction leads to a short service life, especially on rainy days, due to the high humidity in the air, the sanding belt paper and the wire are damp, the sanding belt is more easily worn, and the service life is reduced. Due to the wear and tear, the sanding belt needs to be replaced frequently, resulting in reduced work efficiency. The sanding belt tension needs to be adjusted when the sanding belt is replaced. Loose tension cannot achieve the required effect, and high tension is easy to wear the parts of the machine itself. The belt sander only has two sets of belts rotating. When the wire is pulled in, there will be areas where there is no friction during rotation and movement, and there will be residual oxide layers that are not completely removed, thus affecting subsequent production operations.
