Description

Technical Field

[0001] The invention belongs to the technical field of deep processing of metal wires, and in particular relates to a metal mesh fixing nail processing system. Background Art

[0002] In the process of fixing the metal mesh on the surface of the target area, fixing nails are generally used to fix it. Most of the existing fixing nails are made of hard metal wire, that is, the metal wire is cut and then bent into a U-shaped structure. However, when fixing the metal mesh, the two fixed ends of the fixing nails are not in a pointed cone shape, and it is more difficult to insert them into the surface of the target area. Moreover, during processing, in order to ensure the smoothness of the entire process, a metal wire coil is generally used, and the metal wire coil is unwound and straightened. However, the existing unwinding is generally passive unwinding, which is very easy to unwind too slowly or too quickly, causing the unwound metal wire to be too tight or too loose. When the metal wire is too tight, the metal wire coil is forced to be passively tightened, causing the curled metal wires that make up the metal wire coil to be excessively intertwined and tightened, making the metal wire coil disordered, and at the same time affecting the straightening operation of the metal wire by the straightening equipment; when the metal wire is too loose, the unwound metal wire will become tangled; and the smoothness of the metal wire cannot be ensured when it is unwound, making straightening more difficult and causing the quality of the prepared fixing nails to be reduced. Summary of the Invention

[0003] The present invention provides a metal mesh fixing nail processing system, which is used to unwind a metal wire roll at a uniform speed, perform smoothness adjustment on the metal wire before straightening, suppress the shaking caused by unwinding the metal wire, avoid the situation where the metal wire is too tight or too loose, reduce the difficulty of straightening the metal wire, and perform end processing on both ends of the cut metal wire so that the prepared fixing nail can be smoothly anchored on the surface of the target area.

[0004] To achieve the above object, the technical solutions adopted by the present invention are as follows:

The self-pressure plate presses on the upper end of the wire roll, and the vertical center rod is transmission-connected to the first drive assembly.

[0007] Furthermore, a plurality of first strip holes are evenly opened on the bottom wall of the support frame along its circumference, and each of the first strip holes extends radially along the vertical center rod; a plurality of second strip holes are opened on the self-pressure plate, and the second strip holes extend radially along the vertical center rod; the lower end of each vertical support rod is detachably connected to the support frame through the first strip hole, and the upper end of the vertical support rod is movably extended out of the corresponding second strip hole.

[0008] Furthermore, the secondary elastic wire adjustment mechanism includes a coaxially arranged base disk and an assembly ring, and a plurality of mounting rails are evenly fixed along the circumference of the base disk between the base disk and the assembly ring. Each of the mounting rails extends radially along the base disk, and a wire adjustment seat is movably connected to each mounting rail, and an elastic adjustment component is arranged between the wire adjustment seat and the assembly ring.

[0009] Furthermore, the wire adjusting seat includes a seat body slidably assembled on the mounting rail, a second strip mounting hole extending along the guide of the mounting rail is opened on the seat body, two second vertical shafts are installed in the second strip mounting hole at intervals along its length direction, and a second rolling wheel is coaxially connected to each of the second vertical shafts, and a second rolling gap is formed between the two second rolling wheels, and the metal wire passes through the second rolling gap.

[0010] Furthermore, the elastic adjustment component includes an adjustment screw extending radially along the assembly ring and threadedly connected to the assembly ring, and a buffer spring is rotatably connected to one end of the adjustment screw close to the wire adjustment seat. The buffer spring extends along the length direction of the adjustment screw and is fixedly connected to the wire adjustment seat.

[0011] Furthermore, the straightening mechanism includes an upper rolling assembly and a lower rolling assembly that are relatively arranged up and down. The lower rolling assembly is transmission-connected to the second drive assembly. Vertical screws are rotatably connected at both ends of the upper end of the upper rolling assembly, and each of the vertical screws is threadedly connected to a transfer seat.

[0012] Furthermore, the wire cutting mechanism includes two wire pressing seats arranged at intervals along the length direction of the straightened metal wire, the two wire pressing seats are located above the inlet end of the cooling conveying mechanism, a transverse beam is elastically connected above the two wire pressing seats, a vertical driving member is installed at the upper end of the transverse beam, and a vertical cutting component is elastically connected to one end of the transverse beam close to the straightening mechanism.

[0013] Furthermore, the cooling conveying mechanism includes two connecting shafts connected to the machine body and rotating at intervals along the conveying direction of the cut metal wire.

During this process, the secondary elastic wire adjustment mechanism elastically stretches the passing metal wire, on the one hand, ensuring that the metal wire maintains a uniform motion state through the process, and on the other hand, due to the action of the elastic external tension, the secondary elastic wire adjustment mechanism adjusts the smoothness of the metal wire more evenly and smoothly, thereby avoiding the occurrence of metal wire jamming, bouncing, etc. After the metal wire is adjusted by the straightening mechanism, it is cut into a predetermined length by the wire cutting mechanism, and then gradually transported to the bending equipment by the cooling conveying mechanism; during the transportation process, the end grinding mechanism and the cooling conveying mechanism cooperate to synchronously grind the two ends of the cut metal wire, so that the two ends of the cut metal wire are ground into a pointed cone shape, thereby facilitating the fixing nail formed after bending to be smoothly anchored on the surface of the target area; at the same time, the cooling conveying mechanism heat exchanges the heat generated by grinding the end of the metal wire when conveying the cut metal wire, thereby avoiding the situation where the temperature of the grinding area is too high. In summary, the present invention can effectively unwind the metal wire roll at a uniform speed, adjust the smoothness of the metal wire before straightening it, suppress the shaking of the metal wire caused by unwinding, avoid the situation where the metal wire is too tight or too loose, reduce the difficulty of straightening the metal wire, and perform end processing on the two ends of the cut metal wire so that the fixing nail can be smoothly anchored on the surface of the target area.

DETAILED DESCRIPTION

[0036] 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.

[0037] The present invention discloses a metal mesh fixing nail processing system, such as Figure 1-17As shown, it includes an adjustable self-pressure unwinding mechanism 100, a first-level wire adjustment mechanism 200, a second-level elastic wire adjustment mechanism 300, a straightening mechanism 400, a wire cutting mechanism 500 and a cooling conveying mechanism 600, which are arranged in sequence along the processing direction of the metal wire. An end grinding mechanism 700 is arranged above the cooling conveying mechanism 600. The metal wire coil is sheathed outside the adjustable self-pressure unwinding mechanism 100, and the straightened metal wire is cut by the wire cutting mechanism 500, and then passed through the gap between the cooling conveying mechanism 600 and the end grinding mechanism 700 in a row. The two ends of each cut metal wire are polished into a pointed cone shape by the end grinding mechanism 700. The working principle and advantage of the present invention are: the present invention actively unwinds the metal wire coil through the adjustable self-pressure unwinding mechanism 100. During the unwinding process, due to the limitation of the adjustable self-pressure unwinding mechanism 100, the metal wire coil is prevented from vertical movement, thereby ensuring the purpose of smooth and uniform unwinding. The unwound metal wire passes through the primary wire adjusting mechanism 200 and the secondary elastic wire adjusting mechanism 300 in sequence. The primary wire adjusting mechanism 200 performs primary adjustment on the uneven parts of the metal wire, that is, the metal wire enters the secondary elastic wire adjusting mechanism 300 after wrapping around the primary wire adjusting mechanism 200 for one circle; the secondary elastic wire adjusting mechanism 300 performs secondary elastic adjustment on the smoothness of the metal wire, that is, the metal wire enters the straightening mechanism 400 after wrapping around the secondary elastic wire adjusting mechanism 300 for one circle. During this process, the secondary elastic wire adjusting mechanism 300 elastically stretches the passing metal wire, on the one hand, to ensure that the metal wire maintains a uniform motion state through, and on the other hand, due to the action of the elastic external tension, the secondary elastic wire adjusting mechanism 300 adjusts the smoothness of the metal wire more evenly and smoothly, avoiding the occurrence of metal wire jamming, bouncing, etc. After the metal wire is adjusted by the straightening mechanism 400, it is cut into a predetermined length by the wire cutting mechanism 500, and then gradually conveyed to the bending equipment by the cooling conveying mechanism 600; during the conveying process, the end grinding mechanism 700 and the cooling conveying mechanism 600 cooperate to synchronously grind the two ends of the truncated metal wire passing through, so that the two ends of the truncated metal wire are ground into a pointed cone shape, thereby facilitating the fixing nails formed after bending to be smoothly anchored on the surface of the target area; at the same time, when conveying the truncated metal wire, the cooling conveying mechanism 600 also exchanges heat with the heat generated by grinding the ends of the metal wire to avoid excessive temperature in the grinding area. In summary, the present invention can effectively unwind the wire roll at a uniform speed, perform smoothness adjustment before straightening the wire, suppress the shaking caused by unwinding the wire, avoid the situation where the wire is too tight or too loose, reduce the difficulty of straightening the wire, and perform end processing on both ends of the cut wire so that the obtained fixing nail can be smoothly anchored on the surface of the target area.

[0038] As a preferred embodiment of the present invention, Figure 2 、 3As shown, the adjustable self-pressing unwinding mechanism 100 includes a fixed seat 101, a vertical center rod 102, a support frame, a self-pressing plate 109, a first drive assembly and a plurality of vertical support rods 106. Among them, the vertical center rod 102 is coaxially rotatably mounted on the fixed seat 101, the support frame is coaxially fixed on the vertical center rod 102, and the above-mentioned plurality of vertical support rods 106 are evenly mounted on the support frame along the circumference of the support frame. The self-pressing plate 109 is arranged above the support frame, and the self-pressing plate 109 is movably connected to the vertical center rod 102 and each vertical support rod 106, and the axis of the self-pressing plate 109 coincides with the axis of the vertical center rod 102. The wire roll is placed in the support frame, and each vertical support rod 106 is supported on the inner circumferential wall of the wire roll. The self-pressing plate 109 is movably pressed on the upper end of the wire roll, and the vertical center rod 102 is transmission-connected to the first drive assembly. The specific structure of the first drive assembly is as follows: the first drive assembly includes a first drive motor 111, a driving wheel 112, and a driven wheel 113. The first drive motor 111 is mounted on the fixed base 101, the driving wheel 112 is coaxially mounted on the output shaft of the first drive motor 111, and the transmission wheel 608 is coaxially mounted on the vertical center rod 102. The working principle and advantages of this embodiment are as follows: this embodiment controls the operation of the first drive motor 111 so that it drives the vertical center rod 102 to rotate and drive the support frame to rotate, so that the wire roll rotates accordingly and the wire roll can be unwound continuously and at a uniform speed; at the same time, the self-pressing plate 109 is pressed on the upper end of the wire roll under the action of gravity, thereby preventing the wire roll from vertically moving. Moreover, the wire roll of this embodiment, supported by the vertical support rod 106, ensures that the wire roll and the support frame rotate synchronously, thereby improving the stability of unwinding.

[0039] As a preferred embodiment of the present invention, Figure 2 、 3As shown, the support frame includes a fixed ring 104 and multiple adapter plates 103. These adapter plates 103 are evenly arranged along the circumference of the fixed ring 104, and the fixed ring 104 coincides with the axis of the vertical center rod 102. The adapter plates 103 of this embodiment are bent, having a horizontal connecting portion and a curved portion that extends outward. The connecting portion is fixedly connected to the vertical center rod 102, and the curved portion is connected to the fixed ring 104. Each connecting portion is provided with a first strip-shaped hole 105, which extends radially along the vertical center rod 102. The self-pressing plate 109 is provided with multiple second strip-shaped holes 110, each of which extends radially along the vertical center rod 102. A connector 107 is constructed at the lower end of each vertical support rod 106. This connector 107 vertically passes through the corresponding first strip hole 105. A connecting nut 108 is threadedly connected to the connector 107. This connecting nut 108 fastens the connector 107 to the corresponding connection portion, thereby achieving the purpose of detachable connection between the lower end of the vertical support rod 106 and the support frame. The upper end of the vertical support rod 106 movably extends out of the corresponding second strip hole 110. In this embodiment, the connection position of the vertical support rod 106 and the support frame can be adjusted according to the inner diameter of the wire coil, thereby ensuring that the vertical support rod 106 supports the inner circumferential wall of the wire coil.

[0040] As a preferred embodiment of the present invention, Figure 4 、 5As shown, the primary wire adjustment mechanism 200 includes an annular seat 201, with a plurality of first strip-shaped mounting holes 202 uniformly formed along its circumference. Each first strip-shaped mounting hole 202 extends radially from the annular seat 201. Two first vertical shafts 203 are disposed at each first strip-shaped mounting hole 202, spaced apart along the length of the first strip-shaped mounting hole 202. A first rolling wheel 204 is rotatably connected to each first vertical shaft 203, and a first fastening nut 205 is threadedly connected to the first vertical shaft 203, securing the first vertical shaft 203 to the annular seat 201. A first rolling gap is formed between the two first rolling wheels 204, through which the metal wire passes in an annular shape through each first rolling gap before being introduced into the secondary elastic wire adjustment mechanism 300. As the metal wire passes through the first rolling gap, it is rolled by the two opposing first rolling wheels 204, thereby rolling the deformed portions of the metal wire into a smooth state. Furthermore, the spacing between the two opposing first rolling wheels 204 can be adjusted according to the radial length of the metal wire, thereby adjusting the size of the first rolling gap. In this embodiment, the positions of the two first vertical axes 203 located at the first strip-shaped mounting hole 202 can be adjusted at the first strip-shaped mounting hole 202, thereby adjusting the curvature of the metal wire passing through the first-stage wire adjustment mechanism 200. In this way, the smoothness of metal wires with different hardness and rigidity can be adjusted in a targeted manner; that is, when processing a metal wire with greater rigidity, it is necessary to adjust the first-stage wire adjustment mechanism 200 so that the curvature of the metal wire is reduced during the process of passing through the first-stage wire adjustment mechanism 200; when processing a metal wire with less rigidity, it is necessary to adjust the first-stage wire adjustment mechanism 200 so that the curvature of the metal wire is increased during the process of passing through the first-stage wire adjustment mechanism 200, and the length of the metal wire passing through the first-stage wire adjustment mechanism 200 is reduced, that is, the passing distance of the metal wire is shortened to prevent the metal wire from being twisted, vibrating, deformed, etc. due to being too long.

[0041] As a preferred embodiment of the present invention, Figure 6-9As shown, the secondary elastic wire adjustment mechanism 300 includes a base plate 301, an assembly ring 302, and multiple wire adjustment seats 304. The base plate 301 is coaxially disposed within the assembly ring 302. Multiple mounting rails 303 are fixedly disposed uniformly along the circumference of the base plate between the base plate 301 and the assembly ring 302. Each mounting rail 303 extends radially along the base plate 301. The multiple wire adjustment seats 304 are movably mounted on the mounting rails 303 in a one-to-one correspondence. An elastic adjustment assembly 305 is disposed between the assembly ring 302 and each wire adjustment seat 304. The wire adjustment seat 304 of this embodiment includes a seat body 3041, which is slidably assembled on the mounting rail 303. A second strip-shaped mounting hole 3043 is formed in the seat body 3041 and extends along the guide of the mounting rail 303. Two second vertical shafts 3044 are mounted in the second strip-shaped mounting hole 3043. The two second vertical shafts 3044 are spaced apart along the length of the second strip-shaped mounting hole 3043. A second rolling wheel 3045 is coaxially connected to each second vertical shaft 3044 for rotation. A second fastening nut 3046 is threadedly connected to the second vertical shaft 3044, and the second fastening nut 3046 secures the second vertical shaft 3044 to the seat body 3041. A second rolling gap is formed between the two second rolling wheels 3045, through which the metal wire passes. The metal wire passes through each second rolling gap in a circular shape, and the winding direction of the metal wire at the secondary elastic wire adjustment mechanism 300 is opposite to the winding direction at the primary wire adjustment mechanism 200, that is, one is clockwise and the other is counterclockwise, thereby ensuring that the uneven parts of the metal wire are fully rolled smooth. In the process of passing through the second rolling gap, the metal wire is rolled by two opposing second rolling wheels 3045, thereby rolling the deformed parts of the metal wire into a smooth shape. In addition, the spacing between the two opposing second rolling wheels 3045 can be adjusted according to the radial length of the metal wire, thereby adjusting the size of the second rolling gap. Its operation method, principle, and advantages are the same as those of the adjustment of the first rolling wheel 204 on the primary wire adjustment mechanism 200, and will not be repeated here. The elastic adjustment component 305 of this embodiment includes an adjusting screw rod 3051, a spring seat 3052 and a buffer spring 3053, wherein a connecting ear 3042 is constructed on the adjusting screw rod 3051, the adjusting screw rod 3051 is threadedly connected to the assembly ring 302, and a first operating handwheel 3054 is installed at the end of the adjusting screw rod 3051 away from the base disk 301, the spring seat 3052 is rotatably connected to the other end of the adjusting screw rod 3051, and the adjusting screw rod 3051 extends radially along the assembly ring 302, one end of the buffer spring 3053 is fixedly connected to the spring seat 3052, and the other end of the buffer spring 3053 is fixedly connected to the connecting ear 3042, and the buffer spring 3053 extends along the length direction of the adjusting screw rod 3051.The working principle and advantages of this embodiment are as follows: due to the provision of the elastic adjustment component 305, the position of the wire adjustment seat 304 on the mounting rail 303 can be adjusted by rotating the adjustment screw rod 3051, thereby significantly adjusting the curvature of the metal wire passing through the wire adjustment seat 304. Moreover, when smoothly adjusting the metal wire with greater rigidity, the external force generated by the metal wire contacting the two second rolling wheels 3045 is absorbed by the buffer spring 3053, thereby avoiding damage to the metal wire and the wire adjustment seat 304 caused by the inability to remove the force generated by the hard contact between the metal wire and the two second rolling wheels 3045. In the process of adjusting the metal wire through the secondary elastic wire adjustment mechanism 300, a dynamic balance state is formed between the metal wire and each wire adjustment seat 304, making the entire adjustment operation smoother; and the secondary elastic wire adjustment mechanism 300 can adapt to the adjustment operation of metal wires with different rigidity and hardness; under different traction forces on the metal wire, the secondary elastic wire adjustment mechanism 300 also performs self-adjustment through the deformation of the buffer spring 3053.

[0042] As a preferred embodiment of the present invention, Figure 10 、 11As shown, the straightening mechanism 400 includes an upper rolling assembly and a lower rolling assembly, which are arranged in a vertically opposed relationship. The lower rolling assembly is connected to a second drive assembly, and the upper rolling assembly can also be connected to another second drive assembly as needed. Vertical screws 413 are rotatably connected at both ends of the upper end of the upper rolling assembly. Each vertical screw 413 is threadedly connected to an adapter 412. A second operating handwheel 414 is mounted at the upper end of the vertical screws 413, and the adapter 412 is detachably connected to the frame. The wire passes through the straightening gap between the upper and lower rolling assemblies. Driven by the second drive assembly, the lower rolling assembly is activated, or the lower and upper rolling assemblies operate synchronously, thereby continuously rolling and straightening the wire. By adjusting the vertical screws 413, they drive the upper rolling assembly to move vertically, thereby adjusting the size of the straightening gap to facilitate straightening of wires of different radial lengths. The lower rolling assembly of this embodiment includes a lower assembly seat 401, on which a plurality of first shafts 403 are connected for rotation at intervals along the direction of movement of the metal wire, and a lower adjustment straight wheel 405 is coaxially mounted on each first shaft 403. The upper rolling assembly of this embodiment includes an upper assembly seat 402, on which a plurality of second shafts 404 are connected for rotation at intervals along the direction of movement of the metal wire, and an upper adjustment straight wheel 406 is coaxially mounted on each second shaft 404, and the upper adjustment straight wheels 406 and the lower adjustment straight wheels 405 are arranged in a one-to-one correspondence. In this embodiment, the transmission connection between the second drive assembly and the lower rolling assembly is taken as an example. The second drive assembly includes a second drive motor 411, which is installed on the lower assembly base 401. A first wheel body 408 is coaxially installed on each first shaft 403. A transfer shaft 407 is provided between two adjacent first shafts 403. Each transfer shaft 407 is rotationally connected to the lower assembly base 401. A second wheel body 409 is installed on the transfer shaft 407.
