Description

Technical Field

[0001] This invention belongs to the field of high-speed wire processing technology, and particularly relates to a high-speed wire cooling and winding mechanism. Background Technology

[0002] In the current field of high-speed wire rod processing technology, high-speed wire rod is a type of wire rod, usually referring to coiled wire rod rolled using a "high-speed twist-free rolling mill". High-speed wire rod needs to be rolled by a hot rolling mill, and after hot rolling, it needs to be cooled by a cooling bed and then wound up using a winding mechanism. Utility model patent CN212424948U discloses a metal wire winding device, relating to the field of metal wire winding technology. The metal wire winding device is mounted on a frame, which is fixed to the ground. The device includes a guide rod wire laying device, a winding device, and a transmission device, all mounted on the frame. The winding device includes a rotating shaft, a positioning sleeve fixedly connected to the rotating shaft, a winding reel detachably connected to the rotating shaft, and a locking nut threadedly connected to the rotating shaft. The winding reel is located between the locking nut and the positioning sleeve, thus ensuring sufficient clamping of the winding reel. The transmission device controls both the guide rod wire laying device and the winding device. This utility model has the advantages of enabling uniform metal wire distribution and sufficient clamping of the winding reel.

[0003] However, the aforementioned patents have the following shortcomings: 1. In the above patent, the metal wire is wound by a take-up reel. When the take-up reel rotates, the metal wire is easily wound in the same position on the take-up reel and cannot be evenly distributed on the take-up reel. This results in uneven weight distribution on the take-up reel, which can easily cause accidents when disassembling the take-up reel and has low safety. 2. In the aforementioned patents and commonly used winding devices, when winding rolled high-strength wire, impurities such as shell dust are easily left on the surface of the cooled high-strength wire. Direct winding will easily cause these impurities to be mixed into the wire roll, reducing the winding quality of the high-strength wire. Summary of the Invention

[0004] This invention provides a high-strength wire cooling and winding mechanism, which aims to solve the problems mentioned in the background above, such as high-strength wire easily getting tangled in the same position on the take-up reel, making it impossible to distribute evenly on the take-up reel, resulting in uneven weight distribution on the take-up reel, which can easily lead to accidents and low safety when disassembling the take-up reel. At the same time, impurities such as the outer sheath of the high-strength wire can easily get mixed into the wire roll, reducing the winding quality of the high-strength wire.

[0005] The present invention is implemented as follows: a high-strength wire cooling and winding mechanism includes a winding assembly for collecting high-strength wire, the winding assembly including a "U"-shaped support frame, the bottom wall of which is fixedly mounted with a base; An adjustment component for adjusting the winding position of the high wire, the adjustment component being fixedly mounted on the support frame; A cleaning component for cleaning high lines, the cleaning component being fixedly mounted on the base.

A bevel gear is installed at the output end of the geared motor that meshes with the bevel gear. In this scheme, the geared motor drives the drive shaft to rotate through gear transmission, which in turn drives the take-up roller to rotate, and the take-up roller is used to take up the high-strength wire.

[0007] Preferably, clamping devices are fixedly installed at the ends of both the drive shaft and the driven shaft; The clamping device includes clamping discs, and two clamping discs are respectively fixedly installed at the ends of the drive shaft and the driven shaft; A bidirectional threaded rod is rotatably mounted inside the clamping disc. Two sliders are threadedly connected to the bidirectional threaded rod, and clamping plates are provided on the two sliders. A drive motor is fixedly mounted on the clamping disc, and the drive motor is driven by the bidirectional threaded rod. In this scheme, the drive motor drives the bidirectional threaded rod to rotate, and the position of the two sliders is adjusted by the rotation of the bidirectional threaded rod. The clamping plates move with the sliders, and the end of the take-up roller is clamped by the two clamping plates.

[0008] Preferably, the two clamping devices clamp the two ends of the take-up roller respectively, and the take-up roller is provided with two baffles, and both ends of the two baffles are provided with slots; Two hydraulic push rods are fixedly installed on the base. Each of the two hydraulic push rods has a support seat fixedly installed at its telescopic end. The two support seats correspond to the two slots. In this scheme, the height of the two support seats is adjusted by telescopically extending the telescopic ends of the two hydraulic push rods. Both support seats are provided with arc-shaped surfaces. The slots are viewed through the arc-shaped surfaces, which in turn support the unwound take-up roller and drive the take-up roller to move longitudinally, facilitating subsequent hoisting or moving of the take-up roller.

[0009] Preferably, the adjustment assembly includes an adjustment frame, which is fixedly mounted on the support frame; A drive screw is rotatably mounted on the adjusting frame, and a sliding nut is threaded onto the drive screw. A second drive motor is fixedly mounted on the side wall of the adjusting frame, and the second drive motor is driven by the drive screw. In this scheme, the second drive motor drives the drive screw to rotate, thereby causing the sliding nut to move laterally.

[0010] Preferably, an "L"-shaped mounting bracket is fixedly installed on the lower surface of the sliding nut. A support wheel is rotatably installed inside the mounting bracket, and a limiting groove is formed on the support wheel. In this solution, the high wire is received by the limiting groove on the support wheel, and the high wire passes through the limiting groove. The mounting bracket moves horizontally following the sliding nut, thereby driving the high wire to move horizontally during winding, so that the high wire is evenly wound on the winding roller.

[0011] Preferably, two sliding seats are fixedly installed on the inner wall of the adjusting frame. Lifting frames are slidably connected inside both sliding seats. A connecting spring is fixedly installed inside the sliding seats. One end of the connecting spring is fixedly connected to the sliding seat, and the other end is fixedly connected to the lifting frame. A pressure roller is rotatably installed on the two lifting frames. In this solution, the connecting spring applies a force to the lifting frame through its own spring, thereby applying a force to the pressure roller, and applying a force to the high wire during winding through the pressure roller, improving the stability during winding.

[0012] Preferably, the cleaning component includes a gantry, which is fixedly installed on the base, and the gantry is arranged on one side of the support frame.

A second reduction motor is fixedly installed on the outer wall of the gantry, and the second reduction motor is drivingly connected to the brush roller. In this solution, the second reduction motor drives the brush roller to rotate. When the high wire passes through the brush hair layer on the brush roller, the skin and impurities on the surface of the high wire are cleaned through the brush hair layer.

[0013] Preferably, a plurality of cooling fans are fixedly installed on the top wall inside the gantry, and the plurality of cooling fans are arranged above the brush roller. And a collection trough is slidably installed on the gantry, and the collection trough is arranged below the brush roller.

At the same time, two hydraulic push rod electric support seats are installed on the base, and the support seats are used to support the wound winding roller. 2. A driving lead screw driven by a motor is rotatably installed on the adjusting frame. The rotation of the driving lead screw drives the sliding nut to move. The lower end of the sliding nut is rotatably connected to a support wheel through a mounting bracket. The high wire passes through the limiting groove on the support wheel. The support wheel uses the limiting groove to drive the high wire to move horizontally during winding, so that the high wire is evenly wound on the winding roller, making its distribution more uniform, facilitating disassembly and transportation, and having higher safety. 3. A gantry frame is fixedly installed on the base. A motor-driven brush roller is rotatably installed on the gantry frame. The brush layer on the brush roller cleans the passing high wire, removing the outer shell and dust from the high wire.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0021] Please see Figure 1-7 The present invention provides a technical solution: a high-strength wire cooling and winding mechanism, including a winding assembly 1 for collecting high-strength wire. The winding assembly 1 includes a U-shaped support frame 11. A base 111 is fixedly installed on the bottom wall of the support frame 11. A drive shaft 12 and a driven shaft 13 are rotatably installed on the inner walls of both sides of the support frame 11, respectively. A bevel gear 121 is fixedly installed on the drive shaft 12. A geared motor 14 is fixedly installed on the outer wall of the support frame 11. A bevel gear 141 that meshes with the bevel gear 121 is installed at the output end of the geared motor 14. A clamping device 15 is fixedly installed at the ends of both the drive shaft 12 and the driven shaft 13.

[0022] Among them, the geared motor 14 drives the bevel gear 141 to rotate, which in turn drives the drive shaft 12 to rotate through gear transmission, and then the driven shaft 13 rotates accordingly.

[0023] The clamping device 15 includes a clamping plate 151. Two clamping plates 151 are fixedly installed at the ends of the drive shaft 12 and the driven shaft 13, respectively. A bidirectional threaded rod 152 is rotatably installed inside the clamping plate 151. Two sliders 153 are threadedly connected to the bidirectional threaded rod 152. Clamping plates 154 are provided on the two sliders 153. A drive motor 155 is fixedly installed on the clamping plate 151. The drive motor 155 is connected to the bidirectional threaded rod 152.

[0024] In this process, the drive motor 155 drives the bidirectional threaded rod 152 to rotate. When the bidirectional threaded rod 152 rotates in the forward direction, the two sliders 153 move closer to each other, and the two clamping plates 154 move closer to each other, clamping both ends of the take-up roller 16. When the bidirectional threaded rod 152 rotates in the reverse direction, the two sliders 153 move further away from each other, and the two clamping plates 154 move further away from each other, releasing both ends of the take-up roller 16. Both clamping plates 154 are provided with arc-shaped surfaces, and the surfaces of the arc-shaped surfaces are provided with anti-slip textures to improve the clamping force of the clamping plates 154.

[0025] Two clamping devices 15 clamp the two ends of the take-up roller 16 respectively. The take-up roller 16 is provided with two baffles 162. Both ends of the two baffles 162 are provided with slots 161. Two hydraulic push rods 17 are fixedly installed on the base 111. The telescopic ends of the two hydraulic push rods 17 are fixedly installed with support seats 171. The two support seats 171 correspond to the two slots 161.

[0026] In addition, the two support seats 171 are provided with arc-shaped surfaces. The telescopic ends of the two hydraulic push rods 17 extend and drive the support seats 171 to rise. The arc-shaped surfaces on the support seats 171 engage with the slots 161, thereby supporting the winding roller 16 and preventing the winding roller 16 from falling off after the clamping device 15 is released. This facilitates subsequent hoisting and moving of the winding roller 16.

[0027] Adjustment component 2 is used to adjust the winding position of the high-strength wire. Adjustment component 2 is fixedly installed on support frame 11. Adjustment component 2 includes adjustment frame 21, which is fixedly installed on support frame 11. Drive screw 22 is rotatably installed on adjustment frame 21. Sliding nut 221 is threadedly connected to drive screw 22. Drive motor 222 is fixedly installed on the side wall of adjustment frame 21. Drive motor 222 is driven by drive screw 22. "U"-shaped mounting bracket 23 is fixedly installed on the lower surface of sliding nut 221. Support wheel 24 is rotatably installed in mounting bracket 23. Limit groove 241 is opened on support wheel 24.

[0028] In addition, the high wire passes through the support wheel 24 and the movement position of the high wire is restricted by the limiting groove 241. At the same time, the drive motor 222 drives the drive screw 22 to rotate, causing the sliding screw nut 221 to move laterally. The lateral movement of the support wheel 24 drives the high wire to move laterally, so that the high wire is evenly wound on the take-up roller 16, making the take-up roller 16 more evenly stressed and safer.

[0029] Two sliding seats 26 are fixedly installed on the inner wall of the adjusting frame 21. Lifting frames 25 are slidably connected to each of the two sliding seats 26. A connecting spring 261 is fixedly installed inside the sliding seat 26. One end of the connecting spring 261 is fixedly connected to the sliding seat 26, and the other end is fixedly connected to the lifting frame 25. Pressure rollers 251 are rotatably installed on the two lifting frames 25.

[0030] Furthermore, the lifting frame 25 can be slidably connected to the sliding seat 26 via the sliding rods on both sides, and the connecting spring 261 abuts against the lifting frame 25, thereby applying force to the pressure roller 251. The pressure roller 251 is used to limit the position of the high line, so that the high line can be closely attached to the outer wall of the take-up roller 16.

[0031] Cleaning component 3 is used to clean high lines. Cleaning component 3 is fixedly installed on base 111. Cleaning component 3 includes gantry frame 31, which is fixedly installed on base 111 and is located on one side of support frame 11. Brush roller 32 is rotatably installed on the inner wall of gantry frame 31. Brush layer 321 is provided on the outer wall of brush roller 32. Gear reducer motor 322 is fixedly installed on the outer wall of gantry frame 31. Gear reducer motor 322 is connected to brush roller 32 for transmission.

[0032] Specifically, the high-strength wire passes through the brush layer 321 on the brush roller 32. The brush layer 321 is composed of brush bristles. The second gear motor 322 drives the brush roller 32 to rotate, thereby using the brush layer 321 to clean the surface coating and dust and other impurities of the high-strength wire.

[0033] Multiple cooling fans 33 are fixedly installed on the top wall inside the gantry frame 31. The multiple cooling fans 33 are located above the brush roller 32, and a collection groove 311 is slidably installed on the gantry frame 31, which is located below the brush roller 32.

[0034] It should be noted that multiple cooling fans 33 provide secondary cooling for the high-strength wire to prevent residual heat from damaging the take-up roller 16, and blow away the cleaned-out impurities such as the casing, causing them to fall into the collection tank 311 for centralized processing.

[0035] The working principle and usage process of this invention: Please refer to [link / reference]. Figure 1-7The high-strength wire passes sequentially through the brush roller 32 and the support wheel 24 before winding onto the take-up roller 16. The end of the high-strength wire can be fixed to the surface of the take-up roller 16 with bolts. The first reduction motor 14 drives the second bevel gear 141 to rotate, which in turn drives the drive shaft 12 to rotate via gear transmission. The driven shaft 13 then follows suit, driving the take-up roller 16 to rotate and wind up the high-strength wire. The movement of the high-strength wire is limited by the limiting groove 241. Simultaneously, the second drive motor 222 drives the drive screw 22 to rotate, causing the sliding... The nylon 221 moves laterally, and the support wheel 24 moves laterally, which in turn drives the high-strength yarn to move laterally, so that the high-strength yarn is evenly wound on the take-up roller 16, making the take-up roller 16 more evenly stressed. The high-strength lifting frame 25 can be slidably connected to the sliding seat 26 through the sliding rods on both sides. The connecting spring 261 abuts against the lifting frame 25, which in turn applies force to the pressure roller 251. The pressure roller 251 restricts the position of the high-strength yarn, so that the high-strength yarn can be closely attached to the outer wall of the take-up roller 16. The yarn passes through the brush layer 321 on the brush roller 32. 321 consists of bristles. A geared motor 322 drives the brush roller 32 to rotate, thereby using the bristle layer 321 to clean the surface coating and dust and other impurities of the high-strength wire. Multiple cooling fans 33 provide secondary cooling for the high-strength wire to prevent residual heat from damaging the take-up roller 16, and blow away the cleaned coating and other impurities, causing them to fall into the collection trough 311. After winding, two support seats 171 are provided with arc-shaped surfaces. The telescopic ends of two hydraulic push rods 17 extend, driving the support seats 171 to rise, using the support... The arc-shaped surface on the support 171 engages with the slot 161, thereby supporting the take-up roller 16 and preventing the take-up roller 16 from falling off after the clamping device 15 is released. The drive motor 155 drives the bidirectional threaded rod 152 to rotate. The bidirectional threaded rod 152 rotates in the opposite direction, and the two sliders 153 move away from each other. The two clamping plates 154 move away from each other, releasing the two ends of the take-up roller 16. Both clamping plates 154 are provided with arc-shaped surfaces, and the surface of the arc-shaped surfaces is provided with anti-slip textures to improve the clamping force of the clamping plates 154.

[0036] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
