Description

Technical Field

[0001] The invention belongs to the technical field of metal wire processing in metal mesh production, and in particular relates to a metal wire annealing device for metal mesh. Background Art

[0002] Currently, during the production and processing of metal mesh, the metal wires used require annealing to enhance their properties and ensure that the quality of the produced metal mesh meets the required standards. The principle of wire annealing involves heating the wire to a specific temperature, holding it for a period of time, and then slowly cooling it. This eliminates stress within the wire, improves its ductility or toughness, refines its internal grain structure, and improves its mechanical properties and processing performance. However, during the simultaneous annealing of multiple wires, the wires can experience jitter and vibration when unwound from the unwinding drum. Without appropriate measures, the wires can easily become intertwined or tangled, affecting annealing efficiency. Furthermore, after annealing, the wires must be reeled simultaneously, with each wire reeled onto its corresponding reel. However, during the rewinding process, without external intervention, the wires can easily become too loose. Moreover, generally, after annealing, the ductility of the metal wire is improved, so the metal wire can be drawn, that is, the thicker metal wire is gradually drawn into thinner pieces. In this way, corresponding wire drawing equipment is required, and the drawing range of the existing wire drawing equipment is mostly not adjustable. It can be seen that in order to achieve the purpose of wire drawing, the cost of equipment investment is increased, and different types of wire drawing equipment are equipped according to the requirements of different thicknesses.

DETAILED DESCRIPTION

[0038] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention and are not used to limit the present invention.

[0039] The present invention discloses a metal wire annealing device for metal mesh, such as Figures 1 to 19As shown, the wire laying and guiding mechanism 100, the electric heating cabinet 500, the multi-stage cooling trough 600, and the self-tensioning winding mechanism 800 are sequentially arranged along the conveying direction of the metal wire. Among them, one or more adjustable wire-managing mechanisms 300 are arranged between the wire laying and guiding mechanism 100 and the electric heating cabinet 500, and one or more adjustable wire-managing mechanisms 300 are also arranged between the multi-stage cooling trough 600 and the self-tensioning winding mechanism 800. The present invention uses multiple parallel wire guide tubes 400 arranged in the electric heating cabinet 500 and the multi-stage cooling trough 600. Each wire guide tube 400 passes through the electric heating cabinet 500 and the multi-stage cooling trough 600 along the conveying direction of the metal wire, and each metal wire passes through the corresponding wire guide tube 400. Multiple unwinding drums 200 are arranged in an array below the wire laying and guiding mechanism 100. The operating principle and advantages of the present invention are as follows: Multiple unwinding drums 200 unwind multiple wires, which are then guided and preliminarily arranged by a wire routing and guiding mechanism 100. Furthermore, before the wires enter the self-tensioning reeling mechanism 800, they are combed by multiple adjustable wire-straightening mechanisms 300, preventing loosening and tangling during wire transportation and processing. The present invention heats the portion of the wire guide tube 400 into which it extends, heating the wire as it passes through this heated portion of the tube. Furthermore, multi-stage cooling troughs 600 cool the portion of the wire guide tube 400 into which it extends, cooling the wire stepwise as it passes through this cooled portion of the tube. This prevents the wire from cooling too quickly, which could affect the annealing effect, or too slowly, which could affect efficiency. The present invention uses a self-tensioning winding mechanism 800 to wind the annealed metal wire. During the winding process, the self-tensioning winding mechanism 800 elastically tensions the metal wire so that the metal wire is always in a tensioned state, thereby preventing the wound metal wire from becoming loose. Moreover, the present invention can adjust the self-tensioning winding mechanism 800 so that the metal wire being wound is tensioned according to a predetermined tension, thereby achieving the purpose of wire drawing; and the fineness of the wire drawing can be adjusted by adjusting the tension of the metal wire. In summary, the present invention can effectively avoid situations such as the metal wire being scattered, intertwined, and knotted, thereby preventing the efficiency of annealing from being affected, and ensuring that the annealed metal wire is wound in a tensioned state; at the same time, the metal wire can be stably drawn by steplessly adjusting the radial length of the metal wire according to the requirements.

[0040] As a preferred embodiment of the present invention, Figure 2 、 Figure 3 、 Figure 4As shown, the wire routing and guiding mechanism 100 includes a mounting frame 101, a second transverse rod 105, and a plurality of first transverse rods 102. The first transverse rods 102 are spaced apart at the upper end of the mounting frame 101 along the direction of wire feeding. Each first transverse rod 102 is fixedly connected to a plurality of first connecting sleeves 103, each of which is detachably connected to the upper end of the mounting frame 101. A plurality of first guide rollers 104 are rotatably mounted on each first transverse rod 102, and are spaced apart along the length of the first transverse rod 102. A second transverse rod 105 is disposed on the mounting frame 101 near one end of the electric heating cabinet 500. A plurality of second connecting sleeves 106 are fixedly connected to the second transverse rod 105, each of which is detachably connected to the upper end of the mounting frame 101. A plurality of second guide rollers 107 are rotatably mounted on the second transverse rod 105, and are spaced apart along the length of the second transverse rod 105. The metal wire is unwound through the unwinding drum 200, and passes through the corresponding multiple first wire guide wheels 104 in sequence, and then passes through the corresponding second wire guide wheel 107. The function of the first wire guide wheel 104 is to guide the metal wire and perform preliminary sorting. The second wire guide wheel 107 is used to smoothly transition the metal wire to the adjacent adjustable wire management mechanism 300 to ensure that the metal wire is stably transported. The specific structure of the first wire guide wheel 104 in this embodiment is that the first wire guide wheel 104 includes a guide wheel body 1041 and an elastic rubber sleeve 1043, and the inner peripheral wall of the elastic rubber sleeve 1043 is coaxially fixed with a metal sleeve, and the metal sleeve is rotatably sleeved outside the first transverse rod 102, and the guide wheel body 1041 is fixedly sleeved outside the elastic rubber sleeve 1043. A first wire guide groove 1042 is constructed on the outer peripheral surface of the guide wheel body 1041, and the axis of the first wire guide groove 1042 coincides with the axis of the guide wheel body 1041. When the metal wire is conveyed through the first wire guide groove 1042, due to the metal wire being subjected to biased force or changes in force, the guide wheel body 1041 transmits the external force transmitted by the metal wire to the elastic rubber sleeve 1043. The elastic rubber sleeve 1043 absorbs this external force and undergoes a certain elastic deformation, causing the guide wheel body 1041 to tilt to a certain extent, thereby offsetting the additional force borne by the metal wire and preventing the metal wire from being subjected to excessive force and thus causing its performance to deteriorate. In addition, the guide wheel body 1041 can accommodate metal wires coming from multiple angles, eliminating the need to precisely align the metal wire with the guide wheel body 1041, thereby reducing the difficulty of calibration. In this embodiment, a second wire guide groove 108 is constructed on the outer peripheral surface of the second wire guide wheel 107. The axis of the second wire guide groove 108 coincides with the axis of the second wire guide wheel 107, and the diameter of the second wire guide groove 108 gradually expands outward along the radial direction of the second wire guide wheel 107.When the metal wire passes through the second wire guide groove 108 and enters the adjustable wire management mechanism 300, the opening of the second wire guide groove 108 gradually expands outward, so that the metal wire can enter multiple positions of the adjustable wire management mechanism 300 within a certain angle range; that is, the number of metal wires passing through the same second wire guide groove 108 is multiple, and these metal wires can enter the adjustable wire management mechanism 300 smoothly in a dispersed form when leaving the second wire guide groove 108.

[0041] As a preferred embodiment of the present invention, Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 、 Figure 9As shown, the unwinding drum 200 includes a drive seat 205 and a winding drum body 201. The winding drum body 201 is detachably mounted on the drive seat 205. The metal wire to be annealed is wound on the winding drum body 201. The winding drum body 201 is arranged vertically. In this embodiment, a fixing ring 203 is detachably connected to the upper end of the winding drum body 201. A plurality of metal damping wires 204 are installed between the fixing ring 203 and the winding drum body 201. These metal damping wires 204 are evenly arranged along the circumference of the winding drum body 201, and each metal damping wire 204 extends radially outward from the winding drum body 201. A lifting ring 202 is fixed at the center of the upper end of the winding drum body 201 to facilitate the lifting and transfer of the winding drum body 201. The operating principle and advantages of this embodiment are as follows: By controlling the movement of the drive seat 205, it drives the winding drum 201 to rotate and unwind the metal wire to be annealed. The metal wire is diverted vertically by the adjacent first godet 104 and moves along the length of the mounting frame 101. As the metal wire leaves the winding drum 201, it contacts the metal damping wire 204. The metal damping wire 204 effectively offsets the large fluctuations of the metal wire. Specifically, the metal damping wire 204 acts as a limiter and energy dissipator for the metal wire, improving the stability of the metal wire's upward movement and preventing the metal wire from escaping from the corresponding first godet 104. The drive seat 205 of this embodiment includes a fixed seat 2051, a vertical shaft 2052, a pneumatic impeller 2055, an assembly sleeve 2056, and two mounting plates 2054. Among them, the fixed seat 2051 is fixedly installed on the ground, the lower end of the vertical shaft 2052 is rotatably installed on the fixed seat 2051, the two mounting plates 2054 are fixedly installed on the vertical shaft 2052 at intervals in the vertical direction, the pneumatic impeller 2055 is fixed between the two mounting plates 2054, the assembly sleeve 2056 is rotatably set outside the two mounting plates 2054, and the assembly sleeve 2056 is connected and fixed to the fixed seat 2051 through the fixing ear 2059, and the air inlet pipe 2057 and the exhaust pipe 2058 are connected to the assembly sleeve 2056, and the axes of the fixed seat 2051, the vertical shaft 2052, the pneumatic impeller 2055, the assembly sleeve 2056 and the two mounting plates 2054 coincide. In this embodiment, a plug connector 2053 is constructed at the upper end of the vertical shaft 2052, and a plug slot 206 is coaxially constructed at the lower end of the winding drum 201. When the winding drum 201 is assembled on the drive seat 205, the plug connector 2053 is inserted into the plug slot 206. An air intake manifold 900 is provided below the wire routing and guiding mechanism 100. Multiple air intake branch pipes 901 are connected to the air intake manifold 900 in parallel, and each air intake branch pipe 901 is connected to multiple corresponding air intake pipes 2057.The working principle and advantages of this embodiment are as follows: pressurized gas enters each intake branch pipe 901 through the intake main pipe 900, and then directly drives the pneumatic impeller 2055 to rotate through each intake pipe 2057. In this way, the pneumatic impeller 2055 drives the vertical shaft 2052, the two mounting plates 2054 and the wire winding drum 201 to rotate, so that the wire winding drum 201 can unwind the metal wire thereon. After the metal wire on the wire winding drum 201 is unwound, the wire winding drum 201 can be removed and replaced with a new one. In this embodiment, the wire winding drum 201 is connected to the drive seat 205 in a plug-in manner, which facilitates the replacement operation. Moreover, all the drive seats 205 can be driven by pressurized gas to operate, so that all the wire winding drums 201 can unwind synchronously, avoiding deviations due to different unwinding rates.

[0042] As a preferred embodiment of the present invention, Figure 10 、 Figure 11 、 Figure 12As shown, the adjustable wire-managing mechanism 300 includes a transverse vertical plate 301, a wire-managing assembly, and two first vertical lead screws 312. The wire-managing assembly is mounted on one end face of the transverse vertical plate 301, and a plurality of strip-shaped wire-managing holes 302 are spaced along the extension direction of the transverse vertical plate 301, each of which extends vertically. A plurality of connecting ears 304 are configured at the lower end of the transverse vertical plate 301, and these connecting ears 304 are connected to the mounting frame 101 or to the support frame. The two first vertical lead screws 312 are rotatably connected to the upper ends of both sides of the wire-managing assembly, and each first vertical lead screw 312 is threadedly connected to an adapter plate 311, and the adapter plate 311 is detachably connected to the transverse vertical plate 301. The specific structure of the wire-manipulating assembly of this embodiment is as follows: the wire-manipulating assembly includes two vertical seats 305 and multiple pairs of wire-manipulating rods 308. The two vertical seats 305 are symmetrically arranged on both sides of the horizontal vertical plate 301. Vertical slides 303 are respectively provided on both sides of the horizontal vertical plate 301. A vertical slide 306 is constructed on each vertical seat 305. The vertical slide 306 is slidably assembled in the corresponding vertical slide 303, thereby achieving the purpose of vertical sliding connection between the vertical seat 305 and the horizontal vertical plate 301. In this embodiment, multiple strip-shaped mounting holes 307 are spaced apart in the vertical direction on the vertical seat 305, and each strip-shaped mounting hole 307 extends in the vertical direction. The two wire-manipulating rods 308 in each pair of wire-manipulating rods 308 are spaced apart in the vertical direction, and a connector 309 is constructed at both ends of each wire-manipulating rod 308. In this embodiment, multiple pairs of wire rods 308 are installed at each strip-shaped mounting hole 307. A connector 309 at the end of each wire rod 308 passes through the corresponding strip-shaped mounting hole 307. A fastening nut 310 is threadedly connected to the connector 309. By tightening the fastening nut 310, the end of the wire rod 308 is detachably connected to the corresponding vertical seat 305. In this embodiment, the distance between the two wire rods 308 in each pair of wire rods 308 is adjustable, so that the vertical displacement of the metal wire is limited when passing through the horizontal vertical plate 301. Under the constraints of the strip-shaped wire holes 302, multiple metal wires can smoothly pass through the horizontal vertical plate 301 in a predetermined arrangement. In this embodiment, a first operating handwheel 313 is installed at the upper end of each first vertical screw 312. By synchronously rotating the two first operating handwheels 313, the two first vertical screws 312 drive the two vertical seats 305 to move vertically, and then drive the multiple pairs of wire rods 308 thereon to move in the vertical direction, thereby realizing synchronous adjustment of the angle, height, etc. of the metal wire passing through the horizontal vertical plate 301, ensuring that the metal wire passes through the horizontal vertical plate 301 smoothly.

[0043] As a preferred embodiment of the present invention, Figure 13As shown, the multi-stage cooling trough 600 includes a cooling trough body 601 with an open top. Multiple partitions 602 are spaced apart within the cooling trough body 601 along the direction of wire transport. These partitions 602 divide the interior of the cooling trough body 601 into multiple independent cooling chambers 603. Water inlet connectors 604 and drain connectors 605 are located on the outer wall of the cooling trough body 601, located at the positions of each cooling chamber 603. The drain connector 605 is located above the water inlet connector 604. Cooling water of different temperatures enters each cooling chamber 603, resulting in a gradual decrease in the temperature of the cooling water along the direction of wire transport. This results in a gradual and smooth cooling of the wire, preventing excessive or slow cooling that could affect wire performance and annealing efficiency.

[0044] As a preferred embodiment of the present invention, in order to ensure that the metal wire can smoothly transition to the self-tensioning winding mechanism 800, the measures taken are as follows: Figure 1 、 Figure 14 As shown, a transition mechanism 700 is provided at the inlet of the self-tensioning winding mechanism 800. This transition mechanism 700 comprises at least two parallel transition rollers 702. These transition rollers 702 are arranged so that the wire can smoothly transition from the adjustable wire-arranging mechanism 300 to the self-tensioning winding mechanism 800. Two lateral arms 701 are rotatably mounted on either side of these transition rollers 702. After passing through each transition roller 702, the wire smoothly enters the self-tensioning winding mechanism 800.

[0045] As a preferred embodiment of the present invention, Figure 15 、 Figure 16 、 Figure 17 、 Figure 18 、 Figure 19As shown, the self-tensioning winding mechanism 800 includes a plurality of self-tensioning units 802 and a plurality of adjustable wire drawing units 805. The plurality of self-tensioning units 802 are installed between two first longitudinal beams 801 arranged side by side. These self-tensioning units 802 are spaced apart along the length of the first longitudinal beams 801, and the height of these self-tensioning units 802 decreases in the direction away from the multi-stage cooling trough 600. Two second longitudinal beams 803 are arranged side by side below the self-tensioning units 802. The adjustable wire drawing units 805 are installed between the two second longitudinal beams 803. These adjustable wire drawing units 805 are spaced apart along the length of the second longitudinal beams 803. A winding unit 806 is provided below each adjustable wire drawing unit 805, and the adjustable wire drawing units 805 are arranged one-to-one with the self-tensioning units 802. In this embodiment, since the height of the self-tensioning unit 802 is set in a gradient, multiple metal wires are divided into multiple batches and supplied to the corresponding adjustable wire drawing unit 805 respectively, avoiding interference between the metal wires. In addition, the self-tensioning unit 802 can effectively tension the multiple metal wires passing through, avoiding the occurrence of shaking, jumping, etc. due to changes in the force of the metal wires being pulled. The specific structure of the self-tensioning unit 802 in this embodiment is that the self-tensioning unit 802 includes a wire guide rod 8022, a first self-tensioning rod 8023 and a second self-tensioning rod 8024, the axes of the three are parallel, and the wire guide rod 8022, the first self-tensioning rod 8023 and the second self-tensioning rod 8024 are arranged in sequence in a vertical direction downward, and the metal wires pass through the wire guide rod 8022, the first self-tensioning rod 8023 and the second self-tensioning rod 8024 in sequence. Among them, the two ends of the guide rod 8022 are respectively connected to the adapter seat 8021, and the second vertical screw 8027 is rotatably connected to each adapter seat 8021. The second vertical screw 8027 is threadedly connected to the corresponding first longitudinal beam 801, and a second operating handwheel 8028 is installed at the upper end of the second vertical screw 8027. The guide rod 8022 and the same side end of the first self-tensioning rod 8023 are connected through the first connecting arm 8025, and the first self-tensioning rod 8023 and the second self-tensioning rod 8024 are connected through the second connecting arm 8026. A torsion spring is provided at the connection between the first connecting arm 8025 and the adapter seat 8021, and a torsion spring is also provided at the connection between the first connecting arm 8025 and the second connecting arm 8026. In this embodiment, by synchronously rotating the two second operating hand wheels 8028, the two second vertical screws 8027 drive the guide wire rod 8022, the first self-tensioning rod 8023 and the second self-tensioning rod 8024 to rise or fall synchronously, thereby adjusting the self-tensioning unit 802 to a suitable guide wire and self-tensioning height.In this embodiment, a vertical plate 804 is provided on each second longitudinal beam 803 and at the end of each adjustable wire drawing unit 805, wherein the vertical plate 804 includes a vertical plate body 8041, a strip-shaped movable hole 8042 extending in the vertical direction is provided on the vertical plate body 8041, an assembly opening 8043 is provided at the lower end of the vertical plate body 8041, an assembly block 8044 is provided at the lower end of the assembly opening 8043, and assembly ears 8045 are constructed on both sides of the assembly block 8044, respectively. The assembly ears 8045 are detachably connected to both sides of the assembly opening 8043, and the assembly block 8044 extends into the assembly opening 8043. The winding unit 806 of this embodiment includes a winding rod 8061, on which a plurality of winding drums 8062 are mounted at intervals along its length. The ends of the winding rod 8061 are respectively assembled into corresponding assembly openings 8043 and are rotatably connected to the riser body 8041 via assembly blocks 8044. A transmission wheel is coaxially mounted at one end of the winding rod 8061. By driving the transmission wheel to rotate, the transmission wheel drives the winding drums 8062 to rotate via the winding rod 8061, thereby winding the metal wire. The adjustable wire drawing unit 805 of this embodiment includes two wire drawing rollers 8051, which are spaced apart in the vertical direction. A plurality of wire drawing guide grooves 8052 are spaced apart along the length of each wire drawing roller 8051 on its outer circumference. The wire drawing guide grooves 8052 coincide with the axis of the wire drawing roller 8051. Adapter joints 8053 are coaxially constructed at each end of the wire drawing roller 8051. The upper drawing roller 8051 is rotatably connected to the two vertical plates 804 via two adapter joints 8053 thereon. The adapter joints 8053 at each end of the lower drawing roller 8051 flexibly extend through corresponding strip-shaped movable holes 8042. A vertical drive member 8054, typically a hydraulic cylinder, is mounted at the lower end of each second longitudinal beam 803. The drive end of the vertical drive member 8054 is rotatably connected to the corresponding end of the lower drawing roller 8051. The metal wire is wound between the two drawing rollers 8051 (not around each individual drawing roller 8051, but rather around the two drawing rollers 8051 as a single unit, which is wound as a whole). After generally 2-5 turns, it is wound onto the corresponding winding drum 8062. The arrangement of the wire winding around the drawing rollers 8051 prevents the metal wire from becoming slack at a certain point on the winding drum 8062 after passing through the self-tensioning unit 802. In this embodiment, the spacing between the two drawing rollers 8051 can be adjusted by controlling the movement of the vertical drive member 8054. Thus, the metal wire wound between the two drawing rollers 8051 is stretched according to a predetermined tension, gradually thinning the metal wire. Furthermore, in this embodiment, the tension of the metal wire wound between the two drawing rollers 8051 can be adjusted by driving the vertical drive member 8054, thereby producing a metal wire of a corresponding fineness.Since the tensioning force is steplessly adjusted by the vertical drive member 8054, metal wires of any fineness can be obtained, and there will be no situation where some fineness cannot be obtained by tensioning.
