[0017] The beneficial effects of the present invention are as follows:

[0018] 1. In the present invention, when installing the metal wire, the pressure roller moves up and down. First, start the motor. When the motor starts, it drives the rotation of the threaded rod. When the threaded rod rotates, it drives the rotation of another threaded rod through the transmission of the first pulley group, so that the two threaded rods rotate synchronously. The rotation of the threaded rod drives the movement of the first connecting plate, and the movement of the first connecting plate drives the movement of the pressure roller, so that the pressure roller slides out of the washing liquid in the washing tank. Then, place the metal wire at the bottom of the pressure roller. Finally, start the motor again to move the pressure roller downward, press the metal wire into the washing liquid, and clean it. During the operation process, it avoids the contact between the worker's hand and the washing liquid, which not only improves the safety during operation but also improves the convenience during operation.

[0019] 2. With the provision of the limit plate in the present invention, when installing the metal wire, first move the pressure roller and the feeding roller upward. When the wedge block moves upward to the bottom end of the limit plate and contacts it, the wedge block slides into the first connecting plate under the force. The movement of the wedge block drives the movement of the sliding rod, causing the sliding rod to slide to the corner of the chute. The first connecting plate continues to move upward, driving the sliding rod to move upward inside the chute. At the same time, after the wedge block slides into the first connecting plate, the limit block moves to the bottom of the limit plate. The limit plate limits the limit block, causing the second connecting plate to stop moving upward, thereby causing the feeding roller to stop moving and the pressure roller to continue moving upward. The pressure roller and the feeding roller are separated to leave a distance, facilitating the installation or removal of the metal wire and further improving the convenience during operation.

[0020] 3. With the rotation of the feeding roller in the present invention, during the water washing process, the PLC can be used to control the motor to start. When the motor starts, it drives the rotation of the fourth rotating shaft. The rotation of the fourth rotating shaft drives the rotation of the third rotating shaft through the transmission of the second pulley group. The rotation of the third rotating shaft drives the rotation of the second gear. The rotation of the second gear drives the rotation of the first gear. The rotation of the first gear drives the rotation of the second rotating shaft. The rotation of the second rotating shaft drives the rotation of the feeding roller, causing the cleaning cotton to rotate and contact the metal wire, further improving the cleaning effect on the metal wire.

Detailed implementation manners

[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0030] As Figures 1 to 7 shown, in the embodiment of the present invention, the metal wire pretreatment equipment includes a water washing tank 1. A pressing roller 2 is arranged inside the water washing tank 1. One end of each of the two pressing rollers 2 is provided with a first connecting plate 3, and the two first connecting plates 3 are slidably installed inside the water washing tank 1;

[0031] Threaded rods 4 are threadedly connected inside the two first connecting plates 3, and the two threaded rods 4 are drivingly connected through a first pulley group 5. A motor 6 is installed at the bottom of one of the first pulley groups 5.

[0032] When installing the metal wire, first start the motor 6. When the motor 6 starts, it drives the rotation of the threaded rod 4. When the threaded rod 4 rotates, it drives the rotation of the other threaded rod 4 through the transmission of the first pulley group 5, so that the two threaded rods 4 rotate synchronously. The rotation of the threaded rod 4 drives the movement of the first connecting plate 3, and the movement of the first connecting plate 3 drives the movement of the pressing roller 2, so that the pressing roller 2 slides out of the washing liquid in the water washing tank 1. Then, place the metal wire at the bottom of the pressing roller 2. Finally, start the motor 6 again to move the pressing roller 2 downward and press the metal wire into the washing liquid for cleaning. During the operation process, it is avoided that the worker's hand contacts the washing liquid, which not only improves the safety during the operation, but also improves the convenience during the operation.

[0033] As Figures 1 to 4As shown in the figure, a feeding roller 7 is provided at the bottom end of the pressure roller 2. One end of the feeding roller 7 is provided with a second connecting plate 8. The second connecting plate 8 is arranged on the outer wall of the first connecting plate 3. Wedge blocks 9 are embedded in the inner walls on both sides of the first connecting plate 3. Slide bars 10 are fixedly installed on both sides of the wedge blocks 9. The slide bars 10 are embedded in the inner walls of the sliding grooves 11. The sliding grooves 11 are opened in the second connecting plate 8.

[0034] When installing the metal wire, place the metal wire between the pressure roller 2 and the feeding roller 7, and the two limit the metal wire.

[0035] When it is necessary to take out the metal wire, the pressure roller 2 and the feeding roller 7 move up synchronously, which is convenient for taking out the metal wire from the water washing tank 1.

[0036] As Figure 1 and Figure 2 shown, a limiting plate 13 is provided above the wedge block 9. The limiting plate 13 is fixedly installed on the inner wall of the water washing tank 1. A limiting block 14 is provided on one side of the bottom of the wedge block 9. The limiting block 14 is fixedly installed on the side wall of the second connecting plate 8.

[0037] The top end of the wedge block 9 is set as an inclined surface;

[0038] The sliding groove 11 is set as an L shape;

[0039] When installing the metal wire, first move the pressure roller 2 and the feeding roller 7 upward. When the wedge block 9 moves upward to the bottom end of the limiting plate 13 and contacts it, the wedge block 9 is forced to slide into the first connecting plate 3. The movement of the wedge block 9 drives the movement of the slide bar 10, so that the slide bar 10 slides to the corner of the sliding groove 11. The first connecting plate 3 continues to move upward to drive the slide bar 10 to move upward inside the sliding groove 11;

[0040] At the same time, when the wedge block 9 slides into the first connecting plate 3, the limiting block 14 moves to the bottom of the limiting plate 13. The limiting plate 13 limits the limiting block 14 to stop the second connecting plate 8 from moving upward, so that the feeding roller 7 stops moving and the pressure roller 2 continues to move upward. The pressure roller 2 and the feeding roller 7 are separated to leave a distance, which is convenient for installing or taking out the metal wire and further improves the convenience during operation.

[0041] As Figure 4 and Figure 5 shown, the wedge block 9 is slidably installed inside the first connecting plate 3. A spring 12 is arranged between the wedge block 9 and the first connecting plate 3.

[0042] During the upward movement of the first connecting plate 3, when the wedge block 9 contacts the limiting plate 13 and slides into the second connecting plate 8, the spring 12 is deformed by force and stores elastic potential energy;

[0043] During the downward movement of the first connecting plate 3, when the wedge block 9 separates from the limiting plate 13, the elastic potential energy is released by the spring 12 to drive the wedge block 9 to move outward, so that the first connecting plate 3 and the second connecting plate 8 are connected and move together.

[0044] As Figure 1 , Figure 2 and Figure 3 shown, grooves 15 are formed on the outer walls of the pressure roller 2 and the feeding roller 7, and the grooves 15 are evenly distributed.

[0045] The arrangement of the grooves 15 facilitates the limitation of the metal wire, and multiple metal wires can be installed in the multiple grooves 15, which helps to improve the pretreatment efficiency of the metal wire.

[0046] As Figure 1 , Figure 2 and Figure 3 shown, cleaning cotton 16 is installed on the inner wall of the groove 15.

[0047] During the water washing process of the metal wire, one end of the metal wire is installed on the take-up roller, and the rotation of the take-up roller pulls the metal wire to move for continuous cleaning (this is a common technical means and is not shown in the figure);

[0048] When the metal wire is being wound, the outer wall of the metal wire contacts the cleaning cotton 16, which helps to remove stains, impurities and residues on the surface of the metal wire, thus ensuring the cleanliness of the metal wire.

[0049] As Figure 4 and Figure 5 shown, one end of the pressure roller 2 is fixedly connected with a first rotating shaft 17, and the first rotating shaft 17 is rotatably installed inside the first connecting plate 3.

[0050] As Figure 6 and Figure 7 shown, one end of the feeding roller 7 is fixedly installed with a second rotating shaft 21, the second rotating shaft 21 is rotatably installed inside the second connecting plate 8, a first gear 22 is fixedly installed on the outer wall of the second rotating shaft 21, a second gear 23 is meshed and connected to the bottom end of the first gear 22, a third rotating shaft 24 is fixedly installed inside the second gear 23, a fourth rotating shaft 26 is arranged below the third rotating shaft 24, the third rotating shaft 24 and the fourth rotating shaft 26 are driven by a second pulley group 25, and a motor 27 is arranged at one end of the fourth rotating shaft 26.

[0051] During the water washing process, the motor 27 can be controlled by the PLC to start. When the motor 27 starts, it drives the rotation of the fourth rotating shaft 26. The rotation of the fourth rotating shaft 26 drives the rotation of the third rotating shaft 24 through the transmission of the second pulley group 25. The rotation of the third rotating shaft 24 drives the rotation of the second gear 23. The rotation of the second gear 23 drives the rotation of the first gear 22. The rotation of the first gear 22 drives the rotation of the second rotating shaft 21. The rotation of the second rotating shaft 21 drives the rotation of the material feeding roller 7, causing the cleaning cotton 16 to rotate and contact the metal wire, further improving the cleaning effect on the metal wire.

[0052] As Figure 6 and Figure 7 shown, through holes 18 are evenly formed inside the material feeding roller 7, and filter plates 19 are arranged inside each through hole 18. Each filter plate 19 is connected by a connecting shaft 20.

[0053] During the rotation of the material feeding roller 7, the material feeding roller 7 stirs the water washing liquid inside the water washing tank 1. The water washing liquid flows through the through holes 18 and contacts the filter plates 19. The filter plates 19 filter the impurities in the water washing liquid, which can extend its service life, reduce the frequency of replacing the cleaning liquid, thereby helping to reduce production costs and improve production efficiency.

[0054] As Figure 6 and Figure 7 shown, one end of the connecting shaft 20 is embedded inside the material feeding roller 7, and the other end of the connecting shaft 20 is rotatably connected to a mounting plate 28. The mounting plate 28 is embedded at one end of the material feeding roller 7.

[0055] The mounting plate 28 and the material feeding roller 7 are connected by internal and external thread cooperation, which is convenient for removing the filter plate 19 for maintenance and cleaning.

[0056] Working principle and usage process:

[0057] When installing the metal wire, first start the motor 6. When the motor 6 starts, it drives the rotation of the threaded rod 4. When the threaded rod 4 rotates, it drives the rotation of another threaded rod 4 through the transmission of the first pulley group 5, causing the two threaded rods 4 to rotate synchronously. The rotation of the threaded rod 4 drives the movement of the first connecting plate 3. The movement of the first connecting plate 3 drives the movement of the pressure roller 2, causing the pressure roller 2 to move out of the water washing liquid in the water washing tank 1.

[0058] At the same time, the movement of the first connecting plate 3 drives the movement of the wedge block 9. The movement of the wedge block 9 drives the movement of the slide bar 10. The movement of the slide bar 10 is limited by the chute 11 to drive the second connecting plate 8 to move upward. The movement of the second connecting plate 8 drives the movement of the material feeding roller 7, causing the material feeding roller 7 and the pressure roller 2 to move upward simultaneously out of the water washing liquid in the water washing tank 1.

[0059] When the wedge block 9 moves upward to the bottom end of the limit plate 13 and contacts it, the wedge block 9 is forced to slide into the first connecting plate 3. The movement of the wedge block 9 drives the movement of the slide bar 10, causing the slide bar 10 to slide to the corner of the chute 11. The first connecting plate 3 continues to move upward, driving the slide bar 10 to move upward inside the chute 11.

[0060] Meanwhile, after the wedge block 9 slides into the first connecting plate 3, the limit block 14 moves to the bottom of the limit plate 13. The limit plate 13 limits the limit block 14, causing the second connecting plate 8 to stop moving upward. As a result, the feeding roller 7 stops moving, and the pressing roller 2 continues to move upward, separating from the feeding roller 7 to leave a distance.

[0061] Then, place the metal wire in the groove 15 at the bottom of the pressing roller 2.

[0062] Finally, start the motor 6 again to make the pressing roller 2 move downward. After the wedge block 9 moves away from the limit plate 13, the elastic potential energy is released by the spring 12, driving the wedge block 9 to move outward. As a result, the first connecting plate 3 and the second connecting plate 8 are connected and move downward together, pressing the metal wire into the washing liquid.

[0063] During the washing process, the PLC can be used to control the start of the motor 27. When the motor 27 starts, it drives the rotation of the fourth rotating shaft 26. The rotation of the fourth rotating shaft 26 is transmitted through the second pulley set 25 to drive the rotation of the third rotating shaft 24. The rotation of the third rotating shaft 24 drives the rotation of the second gear 23. The rotation of the second gear 23 drives the rotation of the first gear 22. The rotation of the first gear 22 drives the rotation of the second rotating shaft 21. The rotation of the second rotating shaft 21 drives the rotation of the feeding roller 7, causing the cleaning cotton 16 to rotate and contact the metal wire for cleaning.

[0064] During the rotation of the feeding roller 7, the feeding roller 7 agitates the washing liquid in the washing tank 1. The washing liquid flows through the through hole 18 and contacts the filter plate 19. The filter plate 19 filters the impurities in the washing liquid.

[0065] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
