Description

Technical Field

[0001] This invention relates to the field of steel wire production equipment technology, specifically to galvanized steel wire surface treatment equipment and cleaning components. Background Technology

[0002] Due to its excellent corrosion resistance, galvanized steel wire is widely used in many fields such as building components, bridge cables, and power communications. During the production process of galvanized steel wire, the hot-dip galvanizing process and cooling environment can cause zinc liquid to drip and clump, excessively thick zinc layer in some areas, or granular zinc dross protrusions on the surface of the steel wire. In order to ensure that the galvanized steel wire has good dimensional consistency and surface smoothness, it is usually necessary to use surface treatment equipment to scrape and trim the formed steel wire.

[0003] Chinese patent application number 202422956950.3 discloses a steel wire surface cleaning device, including a drive wheel, a cleaning brush, a bracket, and a base. The bracket is fixed on the base, the drive wheel is rotatably connected to the bracket, and the cleaning brush is slidably connected to the bracket, with the cleaning brush located on one side of the drive wheel. A cam is fixedly connected to one side of the drive wheel, and the bottom end of the cleaning brush contacts the outer surface of the cam. A baffle is fixedly connected to the side of the drive wheel away from the cam. The baffle is circular, with its axis coinciding with the axis of the drive wheel, and its diameter is larger than the diameter of the drive wheel. However, conventional galvanized steel wire surface treatment equipment often uses fixed rigid scraping rings or drawing dies to directly scrape off the excess zinc layer on the steel wire surface, resulting in poor cleaning effect and easy damage to the galvanized steel wire.

[0004] When the surface of galvanized steel wire has hard, large granular protrusions or excessively thick zinc layers in some areas, it can cause traction jamming, increasing the risk of wire breakage. It can also cause the protruding parts, along with the normal zinc layer at the bottom, to crack and peel off under stress, damaging the normal zinc layer of the galvanized steel wire and resulting in product defects. In addition, during the cleaning process, the detached zinc shavings can easily adhere to the surface of the steel wire or the cleaning parts, causing secondary scratches on the zinc layer surface. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the existing defects and provide a surface treatment equipment and cleaning components for galvanized steel wire. By adaptively converting rigid scraping into rotary grinding, the large-volume zinc layer protrusions are avoided from causing the scraper ring to jam and the zinc layer to crack.

[0011] As a further embodiment of the present invention, the limiting module further includes a positioning seat, which is staggered vertically along the length of the slot seat. The positioning seat corresponds to the fixed seat and is detachably connected to the slot seat. Positioning pins are threaded through both sides of the positioning seat, and the ends of the positioning pins on both sides abut against the ends of the mounting seat. Locking nuts are threaded onto the positioning pins.

[0012] On the other hand, the present invention also provides a cleaning component, which includes a processing module and a trimming module; The processing module includes: a suspension seat, a movable seat rotatably embedded in the middle of the suspension seat, a scraper ring detachably connected to one side of the movable seat facing the rotation shaft, transmission teeth arranged in a ring array on the other side of the movable seat, a friction ring embedded in the side of the scraper ring, and abrasive adhering to the side of the friction ring; it also includes a guide rod, a sliding seat slidably sleeved on the guide rod, and an elastic telescopic bladder sleeved between the end of the guide rod and the sliding seat. The trimming module includes: a rotating seat, a ring seat detachably connected to the center of the rotating seat, a grinding part on the inner side of the ring seat, and a tooth groove on the side of the ring seat that corresponds to the transmission teeth.

[0013] As a further embodiment of the present invention, the suspension seat and the scraper ring are both sleeved on the outside of the galvanized steel wire, and the inner diameter of the center hole of the scraper ring is the same as the diameter of the galvanized steel wire; the guide rod is located at the end of the groove seat, and the bottom end of the sliding seat is fixedly connected to the suspension seat.

The two air nozzles correspond to the scraping ring and the grinding part, respectively.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. When encountering high hardness or large volume protrusions and thick zinc layers, the steel wire generates a thrust on the scraping ring, causing the movable seat to overcome the elastic force of the elastic expansion bladder and slide backward until the transmission teeth mesh with the tooth groove of the trimming module. At this time, the rotating shaft drives the movable seat and the friction ring to rotate synchronously in both directions, transforming rigid scraping into rotary grinding, effectively avoiding scraping ring jamming or zinc layer cracking, and protecting the steel wire and zinc layer from damage. 2. This invention utilizes an elastic telescopic bladder to pressurize the internal air during reciprocating expansion and contraction, and then sprays it through an air nozzle onto the working area of ​​the scraper ring and grinding section. The high-pressure airflow blows off the zinc dust generated during operation in real time, preventing the debris from adhering and causing secondary scratches on the steel wire surface. This achieves simultaneous surface treatment and pneumatic dust blowing, keeping the inner cavity of the equipment clean. Attached Figure Description

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Example 1: Please see Figure 1-5 This embodiment provides a technical solution: a galvanized steel wire surface treatment device, including two correspondingly arranged bases 1. A fixed shaft 101 is fixedly connected to one base 1, and a rotating shaft 102 is rotatably connected to the other base 1. Both the fixed shaft 101 and the rotating shaft 102 have through holes in their middle parts, and the diameter of the through holes is larger than the diameter of the galvanized steel wire. The through holes are used to allow the galvanized steel wire to enter from the rotating shaft 102 at one end, pass through the limiting module 2 in the slot 107, and exit from the fixed shaft 101.

[0021] A slot 107 is provided between the fixed shaft 101 and the rotating shaft 102. One end of the slot 107 is fixedly connected to the fixed shaft 101, and the other end of the slot 107 is rotatably sleeved on the rotating shaft 102. This allows the rotating shaft 102 to rotate independently while the slot 107 is fixed. A distance sensor is provided on the inner wall of the perforation of the rotating shaft 102. The distance sensor is used to monitor in real time whether the position of the galvanized steel wire deviates from the center of the perforation during the rotation of the rotating shaft 102. If it deviates, the machine is stopped in time for correction to prevent the processing module 3 and the trimming module 4 from having a negative effect on the galvanized steel wire.

[0022] A drive mechanism is provided at the end of the rotating shaft 102 to drive the rotating shaft 102 to rotate. The drive mechanism includes a secondary pulley 103 and a drive motor 104. The secondary pulley 103 is located at the end of the rotating shaft 102, and the drive motor 104 is located on the base 1. The output shaft of the drive motor 104 is provided with a main pulley 105. The main pulley 105 and the secondary pulley 103 are connected by a transmission belt 106. During operation, the drive motor 104 is preferably configured to rotate in both directions, so that the secondary pulley 103 and the rotating shaft 102 are driven to rotate in both directions by the transmission belt 106 through the main pulley 105, so that the distance sensor rotates in both directions around the steel wire, thereby ensuring that the distance sensor has a wide detection range.

[0023] A limiting module 2 is provided on the side of the slot 107 near the fixed shaft 101, and a galvanized steel wire is threaded through the limiting module 2. A cleaning component is provided on the side of the slot 107 near the rotating shaft 102.

[0024] The bottom of the tank 107 is equipped with a negative pressure adsorption module 5, which corresponds to the processing module 3 and the trimming module 4, such as... Figure 3 As shown, the negative pressure adsorption module 5 includes a collection frame, a filter element inside the collection frame, an adsorption pipe at the bottom of the collection frame, and a negative pressure fan on the adsorption pipe. The negative pressure adsorption module 5 is used to adsorb and collect the debris and dust generated by the adsorption and treatment module 3 and the trimming module 4 during the trimming of galvanized steel wire, and to prevent the diffusion of these debris and dust.

[0025] The limiting module 2 includes a U-shaped fixed seat 201, which is staggered vertically along the length of the slot seat 107. The fixed seat 201 is detachably connected to the slot seat 107. An installation seat 202 is fitted inside the fixed seat 201. A limiting wheel 208 is rotatably connected inside the installation seat 202. A limiting groove for cooperating with the galvanized steel wire is opened on the circumferential surface of the limiting wheel 208. A positioning rod 203 is threaded through the middle of the fixed seat 201. A locking nut 204 is threaded on the positioning rod 203. The end of the positioning rod 203 abuts against the end face of the installation seat 202. The locking nut 204 is used to fix and lock the positioning rod 203. The positioning rod 203 abuts against one end of the installation seat 202, thereby positioning one end of the installation seat 202. The limiting groove on the circumferential surface of the limiting wheel 208 is used to limit the galvanized steel wire axially.

[0026] The limiting module 2 also includes a positioning seat 205, which is staggered vertically along the length of the slot seat 107. The positioning seat 205 corresponds to the fixed seat 201 and is detachably connected to the slot seat 107. Positioning pins 206 are threaded through both sides of the positioning seat 205. The ends of the positioning pins 206 on both sides abut against the ends of the mounting seat 202. Locking nuts 207 are threaded onto the positioning pins 206. The locking nuts 207 are used to lock and fix the positioning pins 206 on both sides. The positioning pins 206 abut against the other end of the mounting seat 202 to achieve overall positioning of the mounting seat 202, so that the limiting wheel 208 is staggered vertically along the direction of the slot seat 107, thereby using the limiting wheel 208 to limit the galvanized steel wire in the vertical direction.

[0027] This embodiment also discloses a cleaning component, which includes a processing module 3 and a trimming module 4. The galvanized steel wire passes through the rotating shaft 102 in sequence, then passes through the processing module 3, the trimming module 4, and the limiting module 2 in sequence, and is led out through the hole of the fixed shaft 101. It is then conveyed under the traction of an external traction device. The processing module 3 is used to remove the granular protrusions generated on the galvanized steel wire or to eliminate areas with thicker zinc layers.

[0028] The processing module 3 includes a suspension seat 301, a movable seat 302 is rotatably embedded in the middle of the suspension seat 301, and a scraper ring 303 is detachably connected to the side of the movable seat 302 facing the rotating shaft 102. Both the suspension seat 301 and the scraper ring 303 are sleeved on the outside of the galvanized steel wire. The inner diameter of the center hole of the scraper ring 303 is the same as the diameter of the galvanized steel wire. When the granular protrusions and thick zinc layer on the galvanized steel wire pass through the scraper ring 303, the galvanized steel wire can be removed by the edge of the scraper ring 303. The scraper ring 303 adopts a detachable connection design, which is convenient for later replacement and maintenance.

[0029] The processing module 3 also includes a guide rod 305, which is located at the end of the slot seat 107. A sliding seat 306 is slidably sleeved on the guide rod 305. The bottom end of the sliding seat 306 is fixedly connected to the suspension seat 301. An elastic expansion bladder 307 is sleeved between the end of the guide rod 305 and the sliding seat 306. The elastic expansion bladder 307 is embedded with a spring. The overall elastic expansion and contraction is achieved by utilizing the characteristics of the spring, thereby buffering when high-hardness granular protrusions and thick zinc layers pass by, preventing the zinc layer from being damaged by strong removal.

[0030] Furthermore, during actual operation, when the protruding particles and thick zinc layer pass through the scraper ring 303, they will cause the movable seat 302 and the suspension seat 301 to slide towards one side of the rotating seat 401, and the elastic expansion bladder 307 will be compressed. At the same time, the compressed elastic expansion bladder 307 provides a reverse driving force for the scraper ring 303. Therefore, under normal circumstances, the protruding particles and thick zinc layer can be removed after the elastic expansion bladder 307 is compressed to a certain length. Meanwhile, the elastic expansion bladder 307 will intermittently and irregularly reciprocate elastic expansion and contraction.

[0031] The trimming module 4 includes a rotating seat 401, which is mounted on the end of the rotating shaft 102 via a support arm 402. A ring seat 403 is detachably connected to the center of the rotating seat 401. The ring seat 403 is fitted over the galvanized steel wire. A grinding part 404 is provided on the inner side of the ring seat 403. The grinding part 404 is in contact with the surface of the galvanized steel wire. The rotating shaft 102 can rotate the rotating seat 401 via the support arm 402, which in turn drives the grinding part 404 to rotate. The contact surface between the grinding part 404 and the galvanized steel wire is coated with abrasive, which has a smaller particle size and higher density than the abrasive on the side of the friction ring 304. This allows for fine grinding of the zinc layer on the outer side of the galvanized steel wire, trimming the treated zinc layer and ensuring the smoothness of the galvanized steel wire. Since the grinding part 404 is a consumable part, the ring seat 403 and the rotating seat 401 are detachably connected for easy replacement later.

[0032] During operation, the galvanized steel wire passes through the perforation in the middle of the rotating shaft 102 and enters the slot 107. After passing through the processing module 3, the trimming module 4, and the limiting module 2 in sequence, it exits through the perforation in the middle of the fixed shaft 101 and continues to feed. At the same time, the drive motor 104 is started to drive the main pulley 105 to rotate in both directions. The main pulley 105 transmits power to the auxiliary pulley 103 through the transmission belt 106, which in turn drives the rotating shaft 102 to rotate in both directions. The distance sensor installed in the rotating shaft 102 rotates synchronously with the rotating shaft 102 to monitor the coaxiality of the galvanized steel wire with the center of the perforation in real time. When the galvanized steel wire is detected to deviate from the center threshold, the equipment triggers an early warning program to prevent the processing module 3 and the trimming module 4 from damaging the zinc layer of the galvanized steel wire.

[0033] During the feeding process of galvanized steel wire, the vertically staggered limiting modules 2 in the slot seat 107 provide vertical and axial limiting guidance for the galvanized steel wire. In each set of limiting modules 2, the positioning rod 203 feeds along the threaded hole in the middle of the fixed seat 201 and abuts against the end face of the mounting seat 202. It cooperates with the positioning pins 206 on both sides to limit the abutment on both sides of the other end of the mounting seat 202. After the locking nut 204 and the locking nut 207 are locked and fixed respectively, the position of the mounting seat 202 can be fixed, so that the limiting groove of the limiting wheel 208 cooperates with the galvanized steel wire. The vertically staggered limiting wheels 208 can limit the radial runout and axial displacement of the galvanized steel wire, ensuring the stable transmission of the galvanized steel wire and providing precise position conditions for the work of the processing module 3 and the trimming module 4.

[0034] When the galvanized steel wire passes through the processing module 3, the scraper ring 303 contacts the surface of the galvanized steel wire through the sharp edge of the central hole. If the zinc layer on the surface of the galvanized steel wire is qualified, it can pass smoothly through the scraper ring 303. When there are granular protrusions or local zinc layer thickness exceeding the standard on the surface of the galvanized steel wire, the edge of the scraper ring 303 scrapes off the protrusions and thick zinc layer, realizing the primary cleaning of the surface of the galvanized steel wire. When there are high-hardness protruding particles or thick zinc layer on the galvanized steel wire, it will generate a pushing force on the scraper ring 303, causing the movable seat 302 and the suspension seat 301 to slide along the guide rod 305 towards the trimming module 4. This causes the sliding seat 306 to compress the elastic expansion bladder 307. The reverse elastic force generated by the pressure on the elastic expansion bladder 307 provides continuous scraping pressure for the scraper ring 303. At the same time, it absorbs the impact load through elastic deformation, avoiding rigid scraping that would damage the galvanized steel wire substrate or normal zinc layer, thereby realizing adaptive buffering in the processing process.

[0035] When the galvanized steel wire processed by processing module 3 passes through trimming module 4, the rotating shaft 102 rotates forward and backward, driving the rotating seat 401 to rotate synchronously forward and backward through the support arm 402, which in turn drives the ring seat 403 and the inner grinding part 404 to rotate around the galvanized steel wire. The friction surface of the grinding part 404 is in close contact with the surface of the galvanized steel wire. Through the circumferential forward and reverse rotation, the zinc layer surface of the galvanized steel wire is finely ground and trimmed, eliminating the scratches left by the scraping ring 303, and ensuring the smoothness of the galvanized steel wire surface and the uniformity of the zinc layer thickness.

[0036] Example 2: This embodiment is another preferred implementation of the galvanized steel wire surface treatment equipment. Please refer to [link / reference]. Figure 4-5 The purpose of this improvement is to enhance the equipment's adaptability to handling high-hardness and large-volume granular zinc layer protrusions, avoid zinc layer cracking and jamming problems caused by rigid scraping, and simultaneously achieve real-time cleaning of zinc dust during processing, further ensuring the surface treatment quality of galvanized steel wire and the cleanliness of the working environment. Specific improvements are as follows: A friction ring 304 is embedded on the side of the scraper ring 303. Abrasive is adhered to the side of the friction ring 304. When rotating, the friction ring 304 can grind and remove the high-protrusion zinc layer and thick zinc layer on the galvanized steel wire.

[0037] The other side of the movable seat 302 is provided with a circular array of transmission teeth 312. The side of the ring seat 403 is provided with a tooth groove 405 that corresponds to and engages with the transmission teeth 312. After the suspension seat 301 slides to a position close to the rotating seat 401, the transmission teeth 312 will mesh with the tooth groove 405. Thus, the forward and reverse rotation of the rotating seat 401 will drive the movable seat 302 to rotate in both directions. In this way, the forward and reverse rotation of the friction ring 304 is used to grind and remove protruding particles and thick zinc layers.

[0038] When the galvanized steel wire has high hardness and large granular protrusions or local zinc layer thickness exceeds the standard, the galvanized steel wire cannot pass through the processing module 3 normally and will generate a thrust on the scraper ring 303. After the thrust overcomes the elastic force of the elastic expansion bladder 307, it pushes the movable seat 302 and the suspension seat 301 to slide along the guide rod 305 towards the rotating seat 401. The sliding seat 306 simultaneously compresses the elastic expansion bladder 307 until the transmission teeth 312 on the end face of the movable seat 302 and the tooth grooves 405 on the end face of the ring seat 403 are fully engaged.

[0039] When the drive motor 104 drives the rotating shaft 102 to rotate in both directions via the drive mechanism, the rotating shaft 102 drives the rotating seat 401 and the ring seat 403 to rotate in both directions synchronously via the support arm 402. The ring seat 403 drives the movable seat 302 to rotate in both directions synchronously via the meshing of the tooth groove 405 and the transmission tooth 312, thereby driving the scraper ring 303 and the friction ring 304 on the side to rotate around the galvanized steel wire.

[0040] The abrasive adhering to the side of the friction ring 304 continuously rubs against and grinds the raised side of the galvanized steel wire as it rotates in both directions. Combined with the scraping action of the inner edge of the scraper ring 303, it removes the high-hardness or highly raised zinc layer, thereby avoiding rigid contact between the scraper ring 303 and the zinc layer of the galvanized steel wire, which could lead to jamming or zinc layer cracking, thus improving the surface treatment effect.

[0041] Furthermore, the upper part of the elastic telescopic bladder 307 is provided with an air inlet one-way valve 308, and the bottom of the elastic telescopic bladder 307 is provided with an air guide pipe 309 through an exhaust one-way valve. The bottom of the air guide pipe 309 is provided with two branch pipes 310, and the bottom of the two branch pipes 310 is provided with an air nozzle 311 at an angle. The two air nozzles 311 correspond to the scraper ring 303 and the grinding part 404, respectively.

[0042] The irregular intermittent reciprocating expansion and contraction of the elastic expansion bladder 307 causes changes in the internal air pressure. High-pressure airflow is discharged through the exhaust one-way valve and airflow is drawn in through the intake one-way valve 308. The high-pressure airflow enters the branch pipes 310 and the air nozzles 311 on both sides respectively, and is sprayed towards the grinding section 404 and the scraper ring 303 respectively.

[0043] During the removal of protrusions and thick zinc layers, the axial thrust on the scraper ring 303 fluctuates due to the irregular distribution of the thickness of the zinc layer, the size of the protrusions, and the hardness of the protrusions on the galvanized steel wire surface. This causes the elastic expansion bladder 307 to intermittently and irregularly expand and contract with the reciprocating movement of the sliding seat 306. When the elastic expansion bladder 307 is compressed, the internal air is compressed to form a high-pressure airflow, which flows into the air guide pipe 309 through the exhaust one-way valve at the bottom. After being split by two branch pipes 310, it is sprayed by the air nozzle 311 to the working positions of the scraper ring 303 and the grinding section 404 respectively, so as to blow away the zinc dust generated during the grinding and scraping process from the surface of the galvanized steel wire in time, and avoid the secondary damage to the zinc layer on the surface of the galvanized steel wire caused by the adhesion of the debris.

[0044] When the elastic expansion bladder 307 rebounds and resets, it is under negative pressure inside. It draws in outside air through the upper one-way valve 308 to reserve airflow for the next compressed exhaust. This process is repeated to achieve continuous purging. The zinc dust blown off by the air nozzle 311 falls downward into the bottom space of the slot 107 and is uniformly adsorbed and collected by the negative pressure adsorption module 5 below the slot 107, which prevents dust from accumulating inside the equipment or spreading outward, thus ensuring a clean working environment.

[0045] Once the raised areas on the surface of the galvanized steel wire are completely removed, the axial thrust on the scraper ring 303 disappears, and the rebound force of the elastic telescopic bladder 307 pushes the sliding seat 306 back to its initial position along the guide rod 305. The transmission gear 312 and the tooth groove 405 disengage, the movable seat 302 stops rotating circumferentially, and the equipment automatically returns to the conventional scraping and fine finishing working state of Example 1.

[0046] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural or procedural transformations made based on the content of the present invention specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present invention.
