[0065] Among them, the dust extraction chamber is connected with a dust extraction pump (not shown in the figure) through a dust extraction pipe. The first cleaning part 321 and the second cleaning part 322 can be controlled by a driving structure to reciprocate and clean the copper rod.

[0066] In this embodiment, the driving structure includes:

[0067] A driving chamber, which is formed on the cleaning body 30 and consists of a first driving chamber 41 and a second driving chamber 42 located on both sides of the dust extraction chamber 30a;

[0068] A driving port 43, which is formed on the cleaning body 30 and is communicated with the driving chamber;

[0069] A transmission shaft 44, which is rotatably arranged in the first driving chamber 41 and the second driving chamber 42;

[0070] Driving wheels 45, which are spacedly arranged on the transmission shaft 44;

[0071] A support rod, which has a transmission port 46a for the transmission shaft 44 to pass through and one end passes out of the driving port 43. In this embodiment, a slide rail 46b for the support rod 46 to slide is further provided at the bottom of the driving chamber;

[0072] The return spring 47 is disposed in the driving port 43, and its two ends are respectively against the support rod 46 and the inner wall of the driving port 43;

[0073] Wherein, the cleaning part is mounted on the support rod, and each driving wheel 45 has a protruding driving surface 45a on one side close to the support rod;

[0074] One end of each transmission shaft 44 passes through the cleaning body 30 and is connected to a sprocket 21 that can be driven by a motor 21a. A chain 22 is connected between the sprockets. That is to say, the rotation of the transmission shaft 44 is also controlled by the motor 21a. When the motor 21a drives the sprocket to move.

[0075] In this embodiment, a dust collecting groove 50a which is gradually recessed from both sides to the center is formed on the top of the cleaning body 30, and the dust inlet 31 is arranged at the bottom of the dust collecting groove 50a. The arrangement of the dust collecting groove 50a facilitates the collection of impurities and dust extraction.

[0076] The support rod in this embodiment includes a rod body 460, a support seat 461, an internal threaded hole and a fixing bolt 462; the support seat 461 is arranged on the rod body 460, the internal threaded hole is arranged at the top of the rod body 460, and the fixing bolt 462 cooperates with the internal threaded hole and fixes the cleaning part on the rod body 460.

[0077] In this embodiment, in order to ensure the stability of the movement of the rod body 460, a mutually adaptable limit slider 50 and a limit groove 51 are provided between the rod body 460 and the inner wall of the driving port 43. The limit groove 51 is provided on the inner wall of the driving port 43, and the limit slider 50 is provided on the rod body 460.

[0081] refer to Figures 1-4 When the present embodiment is in use, the copper rod is pulled and passed through the groove of the straightening roller, and after the straightening is completed, it passes over the cleaning body. When passing through the cleaning body, the first cleaning part and the second cleaning part are controlled by the driving structure to reciprocate and wipe the copper rod (i.e., reciprocate in the y direction). At the same time, the dust extraction pump is started, and the dust inlet is used to extract the impurities dropped during the wiping process, thereby completing the cleaning of the copper rod;

[0082] More specifically: The drive structure of this embodiment is driven by a sprocket and a chain. When the transmission shaft rotates and drives the drive wheel to rotate, the convex surface on the drive wheel contacts the rod body and drives the rod body to compress the return spring, causing the rod body to move. When the convex surface of the drive wheel separates from the rod body, the rod body is reset by the return spring, thereby achieving the purpose of the reciprocating movement of the rod body;

[0083] It is worth mentioning that the first cleaning part and the second cleaning part of this embodiment can be disassembled during replacement, which is convenient for cleaning the first cleaning part and the second cleaning part.

[0084] Moreover, the transmission shaft and the lower straightening roller in this embodiment can share a sprocket set, that is to say, this can make the two processes of straightening and cleaning highly synchronous.

[0086] As Figure 5 shown, a cleaning port 70 communicating the dust extraction chamber 30a and the drive chamber is provided on the cleaning body 30 of this embodiment, and a solenoid valve is provided at the cleaning port 70. Among them, the solenoid valve includes:

[0087] A valve seat 71, which is installed on the cleaning body 30;

[0088] A valve plate 72, which is arranged at the cleaning port 70;

[0089] A piston shaft 73, which telescopically moves in the valve seat 71, and a support spring 74 connected to the piston shaft 73 is installed in the valve seat 71;

[0090] An electromagnet 75, which is arranged in the valve seat 71 and generates magnetism when energized to attract the piston shaft 73 to descend.

[0091] In this embodiment, in order to better clean the drive chamber (especially the drive port and the slide rail), a cleaning port is opened on the cleaning body. When the movement of the support rod is abnormal, the electromagnet can be energized, and the valve plate can fall to open the cleaning port. When the dust extraction pump is started, foreign objects in the drive chamber can enter the dust extraction chamber through the cleaning port and be evacuated, thereby ensuring the smooth operation of the cleaning body of this embodiment.

[0092] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
