Description

Technical Field

[0001] The invention relates to the technical field of metal mesh production, and in particular to a metal mesh wire feeding rack and a working method thereof. Background Art

[0002] Hexagonal twisted wire mesh, also known as hexagonal wire mesh or gabion wire mesh, is widely used in water conservancy, roads, gardens, construction, environmental protection, agriculture and other fields due to its unique hexagonal structure and excellent performance. It is mainly used for slope protection, retaining walls, foundation reinforcement, ecological restoration, breeding fences and other projects.

[0003] Before the hexagonal twisted mesh is woven by the twisting machine, the weft wire needs to be made into spring rods by a spring-beating machine, and the spring rods are then loaded into the vertical tube of the twisting machine for weaving the hexagonal mesh. In order to improve efficiency, the spring-beating machine often makes multiple spring rods at the same time, so multiple wire storage racks are required to release the wires to the guide plate of the spring-beating machine. Most of the existing wire storage racks use vertically set steel bar welding racks, which need to guide the steel wires upward. In order to smoothly guide multiple steel wires, current hexagonal twisted mesh manufacturers often use simple heightened wire pay-off racks set above multiple wire storage racks, and use transverse steel beams for bending and guiding, and then transport them to the guide plate. However, the guide plate also moves back and forth on the spring-beating machine, and multiple steel wires lack limit and guide structures on the transverse steel beams. Sometimes they will be entangled and knotted with each other, and the machine needs to be stopped for sorting, which affects the efficiency of the spring-beating work.

[0004] In order to overcome the above problems, a metal mesh wire feeding rack and a working method thereof are needed. Summary of the invention

[0005] The purpose of the present invention is to provide a metal mesh wire feeding rack and a working method thereof, which adopts a transverse roller shaft and a front support plate to guide and convey the steel wire, thereby reducing the winding and knotting of the steel wire and improving the efficiency of the spring making operation.

[0006] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0014] Furthermore, an annular groove is formed on the inner side wall of the disk edge, and an outward-facing protrusion is provided on the cantilever end of the support arm, and the protrusion extends into the annular groove.

[0015] Furthermore, the four groups of guide components are staggered in height and left and right on the front support plate.

[0016] Furthermore, the guiding assembly includes a wire slider and a slide rail groove, the slide rail groove is a long hole horizontally opened on the front support plate, the outer contour of the cross-section of the wire slider is H-shaped and can slide left and right in the slide rail groove, and a guide hole for passing the steel wire is opened in the middle of the wire slider.

[0017] Furthermore, the guiding assembly also includes a dripping assembly, which includes a cover plate, a liquid storage tank and a filler.

[0019] The present invention also discloses a working method of a metal mesh wire feeding rack, which uses any of the metal mesh wire feeding racks described above to feed a plurality of steel wires to a reciprocating guide plate of the spring beating machine.

[0020] Compared with the prior art, the beneficial technical effects of the present invention are:

[0021] The metal mesh wire feeding rack of the present invention can rotate with the bending and guiding of the steel wire by the transverse roller shaft, which greatly reduces the sliding friction resistance and avoids scratching the surface of the steel wire; the steel wire is laterally limited by the edge of the protective disc, which reduces the contact between adjacent steel wires and reduces the winding of the steel wires; through the arrangement of the front support plate and the guide assembly, each steel wire can be guided and spaced above the front side wall of the bracket body, and mutual interference between them is avoided. The metal mesh wire feeding rack of the present invention uses a transverse roller shaft and a front support plate to guide and convey the steel wire, which reduces the winding and knotting of the steel wire and improves the efficiency of the spring making operation.

[0022] In addition, by setting two transverse roller shafts with staggered heights, more than two of the disc guard groups are set on each transverse roller shaft to guide the steel wire, so that the height space can be fully utilized to separate the steel wires, and the wire entry position of the guide plate of the spring-setting machine is also staggered, that is, it has good adaptability with the guide plate. The sleeve portion can be slidably sleeved on the transverse roller shaft and locked by the first top wire, so that the opening size of the disc guard group can be adjusted, which is suitable for wire release of wire storage racks of different sizes. In other words, the transverse roller shaft, the disc edge, the support arm and the square tube crossbeam enclose a closed square opening area, and the steel wire passes through the square opening area. Even if the steel wire is too loose when it is led out from the wire storage rack, it will not be separated from the square opening area, thus avoiding the contact and interference between adjacent steel wires. At the same time, the arm guard is also sleeved on the square tube crossbeam through the square tube sleeve, and can move axially, so that the disc guard groups of different opening sizes can be adapted. By probing the protrusion into the annular groove, the straight seam gap between the support arm and the edge of the disk is completely closed, and even if the wire is thinner, it will not escape from the square mouth area. The four groups of guide components arranged in a staggered manner in height and left and right are used to guide between the horizontal roller shaft and the guide plate of the spring-making machine, which has good adaptability and spacing, and minimizes the mutual interference between the steel wires. Through the vertical guide cooperation of the vertical sleeve and the vertical rod, the height of the front support plate can be adjusted as a whole, and it is convenient to remove or lower the front support plate as a whole to carry out maintenance of the guide component. By sliding the wire slider left and right in the slide rail groove, the applicability of the left and right reciprocating movement of the guide plate of the spring-making machine can be adjusted, and the left and right bending angles of the steel wire can be reduced. By arranging the drip assembly nearby on the wire slider, the lubricating liquid can be supplied to the chamber of the filler nearby, and the filler coats the surface of the steel wire to reduce the microcracks on the surface of the steel wire during the later twisting and weaving, thereby increasing the service life of the hexagonal mesh. Moreover, the drip assembly increases the deadweight of the wire slider, preventing the wire slider from vibrating at high frequencies with the loose steel wire. Through the cooperation of the push rod and the bridge-shaped protrusion, as the guide plate drives the steel wire from one end of the spring-beating machine to the other end, it will also drive the wire slider from one end of the slide rail groove to the other end in one stroke, so that the rear end of the push rod can pass over the bridge-shaped protrusion once, the push rod pushes the valve plate once, the bottom end of the valve plate briefly leaves the liquid outlet slope once, and the liquid outlet pipe outputs a stream of lubricating liquid to the filler, ensuring that the filler is continuously infiltrated with the lubricating liquid and evenly coated on the surface of the steel wire. Moreover, when the equipment is paused, the wire slider stops at a position outside the bridge-shaped protrusion, and the liquid outlet slope is in a state of being closed by the valve plate, avoiding the waste of lubricating liquid during the downtime period. By welding a counterweight block on the side wall of the bottom end of the valve plate away from the rubber pad, the rubber pad can effectively seal the liquid outlet slope under the deadweight pressure of the valve plate and the counterweight block.

[0034] In a specific embodiment, Figures 1 to 5 As shown, the metal mesh wire feeding rack of the present invention conveys the steel wire 10 to the spring beating machine, comprising:

[0035] The support body 1 is a frame structure welded with square tube steel. The support body 1 is arranged across a plurality of wire storage racks 8 for leading out the wires 10. A plurality of vertically arranged wire storage racks 8 are placed at the bottom of the support body 1. The bundled wires 10 are stored flat on the wire storage racks 8, and the leading ends of the wires 10 are led out upward. A top longitudinal beam 101 with a lower front and a higher rear tilted setting is fixed on the top of the support body 1, and the two top longitudinal beams 101 are arranged in parallel. The transverse roller shaft 2 is horizontally arranged on the top of the support body 1. The transverse roller shaft 2 is a round roller. Both ends of the transverse roller shaft 2 are supported on the top surface of the top longitudinal beam 101 through a bearing seat 201, that is, the transverse roller shaft 2 can rotate.

[0036] The disc guard group includes two disc guards 3 used in pairs, and the disc guards 3 are sleeved on the transverse roller shaft 2. The number of the disc guard groups is consistent with the number of the wire storage racks 8 and they are arranged one by one. The steel wire 10 guided upward and forward passes through a group of the disc guard groups and contacts the outer wall of the transverse roller shaft 2, and the guided steel wire 10 is laterally limited by the disc edge 301 of the disc guard 3.

[0037] The front support plate 5 is vertically arranged above the front side wall of the bracket body 1, and a guiding component is arranged on the front support plate 5. The number of the guiding components is consistent with the number of the protective plate groups and is arranged one by one. The guiding component guides the steel wire 10 to the guiding plate of the spring-making machine.

[0038] Compared with the prior art that only uses a transverse steel beam to bend and guide the steel wire 10, the transverse roller shaft 2 in the present invention can rotate while bending and guiding the steel wire 10, which greatly reduces the sliding friction resistance and avoids scratching the surface of the steel wire 10; the steel wire 10 is laterally limited by the edge 301 of the protective plate 3, which reduces the contact between adjacent steel wires 10, thereby reducing the winding of the steel wire 10; through the arrangement of the front support plate 5 and the guiding assembly, each steel wire 10 can be guided and spaced above the front side wall of the bracket body 1, and mutual interference between them is also avoided. The metal mesh wire feeding rack of the present invention uses a transverse roller shaft and a front support plate to guide and convey the steel wire, which reduces the winding and knotting of the steel wire and improves the efficiency of the spring making operation.

[0039] In a specific embodiment of the present invention, Figure 1 As shown, there are two transverse roller shafts 2, which are staggered front and back and arranged in a staggered manner. The two transverse roller shafts 2 are arranged in parallel.

[0040] In fact, the spring beating machine often processes four spring rods at the same time, so it is necessary to guide more than four steel wires 10 synchronously. By setting two transverse roller shafts 2 with staggered heights, more than two guard disc groups are set on each transverse roller shaft 2 to guide the steel wires 10. In this way, the height space can be fully utilized to separate each steel wire 10, and the wire entry position of the guide plate of the spring beating machine is also staggered, that is, it has good adaptability to the guide plate.

[0041] In a specific embodiment of the present invention, Figure 1 and Figure 2 As shown, the protective disc 3 also includes a sleeve portion and a first top screw 302, the sleeve portion can be slidably sleeved on the transverse roller shaft 2, and the disc edge 301 is fixedly connected to the inner end of the sleeve portion. The protective disc 3 is an injection-molded plastic part, and the sleeve portion and the disc edge 301 are integrally formed. A round table with a threaded hole is provided on the side wall of the sleeve portion, and the threaded hole here is threadedly connected to the first top screw 302, and the inner end of the first top screw 302 can be tightly pressed against the outer wall of the transverse roller shaft 2.

[0042] Specifically, if Figure 1 and Figure 2 As shown, the metal mesh wire feeding rack of the present invention also includes a square tube cross beam 4 and an arm guard group. The square tube cross beam 4 is arranged in parallel behind the horizontal roller shaft 2, and the two ends of the square tube cross beam 4 are installed on the top longitudinal beam 101 through the support seat 401. The number of the arm guard group is consistent with the number of the disc guard group and is arranged one by one; the arm guard group includes two arm guards 9 used in pairs, and the arm guard 9 includes a square tube sleeve 901 and a support arm 902. The square tube sleeve 901 is sleeved on the square tube cross beam 4 and locked with a top screw. The root of the support arm 902 is welded on the inner end of the square tube sleeve 901, and the cantilever end of the support arm 902 protrudes into the inner side wall of the disc edge 301.

[0043] Specifically, if Figure 1 and Figure 2 As shown, the support seat 401 is installed with the end of the square tube beam 4 in a sleeve manner and is locked with a top screw to prevent axial movement.

[0044] Specifically, if Figure 1 and Figure 2 As shown, an annular groove is formed on the inner side wall of the disk edge 301, and an outward-facing protrusion is provided at the cantilever end of the support arm 902, and the protrusion is inserted into the annular groove.

[0045] The sleeve portion can be slidably sleeved on the cross roller shaft 2 and locked by the first top wire 302, so that the opening size of the disc guard group can be adjusted, which is suitable for the wire storage racks 8 of different sizes. In other words, the cross roller shaft 2, the disc edge 301, the support arm 902 and the square tube cross beam 4 enclose a closed square opening area, and the steel wire 10 passes through the square opening area. Even if the steel wire 10 is too loose when it is led out from the wire storage rack 8, it will not be separated from the square opening area, thus avoiding the contact and interference between adjacent steel wires 10. At the same time, the arm 9 is also sleeved on the square tube cross beam 4 through the square tube sleeve 901, and can move axially, so that the disc guard groups of different opening sizes can be adapted. The protrusion is inserted into the annular groove, and the straight seam gap between the support arm 902 and the disc edge 301 is completely closed, so that even if the wire 10 is thinner, it will not fall out of the square opening area.

[0046] In a specific embodiment of the present invention, Figure 1 and Figure 3 As shown, most spring-making machines wind four steel wires 10 at the same time. The four groups of guide components are staggered in height and left and right on the front support plate 5. Because the wire entry position of the guide plate of the spring-making machine is also staggered in height, the four groups of guide components are adaptively staggered in height on the front support plate 5. Because the wire storage rack 8 is staggered in left and right, and the disc guard group is also staggered in left and right on the transverse roller shaft 2, the four groups of guide components are adaptively staggered in left and right on the front support plate 5.

[0047] The four groups of guide components which are staggered in height and left and right are used to guide between the transverse roller shaft 2 and the guide plate of the spring beating machine, and have good adaptability and spacing, thereby minimizing mutual interference between the steel wires 10.

[0048] Specifically, if Figure 1 and Figure 3As shown, two vertically arranged vertical rods 501 are fixedly connected at both ends of the front support plate 5, and a vertical sleeve 102 is fixedly connected to the front side wall of the bracket body 1. The vertical rod 501 is vertically guided and inserted into the vertical sleeve 102, and the side wall threaded hole of the vertical sleeve 102 is threadedly connected with a second top screw 502, and the inner end of the second top screw 502 abuts against the outer side wall of the vertical rod 501.

[0049] Through the vertical guide cooperation between the vertical sleeve 102 and the vertical rod 501, the height of the front support plate 5 can be adjusted as a whole, and it is convenient to remove or lower the front support plate 5 as a whole to carry out maintenance of the guide assembly.

[0050] Specifically, if Figure 1 , 3 and Figure 4 As shown, the guide assembly includes a wire slider 6 and a slide rail groove 503. The slide rail groove 503 is a long hole horizontally opened on the front support plate 5. The cross-sectional outer contour of the wire slider 6 is H-shaped and can slide left and right in the slide rail groove 503. The bottom and top edges of the wire slider 6 are clamped to the upper and lower wall plates of the long hole. A guide hole 601 is opened in the middle of the wire slider 6 for passing the steel wire 10.

[0051] Specifically, the wire slider 6 is made of cast iron or tin bronze with good wear resistance.

[0052] By sliding the wire slider 6 left and right in the slide rail groove 503, the adaptability of the left and right reciprocating movement of the guide plate of the spring beating machine can be adjusted to reduce the left and right bending angle of the steel wire 10.

[0053] In a specific embodiment of the present invention, Figure 1 and Figures 3 to 5 As shown, the guide assembly also includes a drip assembly 7, which includes a cover plate 701, a liquid storage tank 702 and a filler 703. The guide hole 601 is a bidirectional speaker channel structure with a small middle and large ends. The filler 703 is pressed into the front speaker hole cavity of the guide hole 601 by the cover plate 701. The filler 703 is made of wear-resistant sponge and can absorb lubricating liquid. The cover plate 701 is fixed to the front side wall of the wire slider 6 by screws at four corners. The cover plate 701 and the guide hole 601 are coaxially provided with a clearance hole 7011 with an increased diameter. The liquid storage tank 702 for storing lubricating liquid is installed on the upper part of the front side wall of the cover plate 701. The liquid storage tank 702 is connected to the chamber of the filler 703 through the liquid outlet pipe 7021 and the liquid guide channel 602. The liquid guide channel 602 is opened on the front side wall of the wire slider 6, and a sealing gasket is used to seal the liquid guide channel 602 and the outer end of the liquid outlet pipe 7021.

[0054] The applicant has been engaged in the production and manufacturing of hexagonal twisted mesh for a long time. During the production process of three-twist or five-twist hexagonal mesh using low-carbon steel wire or galvanized steel wire, it was found that microcracks are prone to appear on the surface of the steel wire 10 at the twisted position, especially when the coating adhesion of the galvanized steel wire is not strong. The reason is that when the steel wire is twisted and braided, it is subjected to mechanical stress such as bending and stretching, which may cause the galvanized layer to peel off or crack, which will affect the corrosion protection of the wire mesh in the later stage and reduce the service life of the wire mesh. The applicant tried to coat the warp wire and the weft wire with a lubricating liquid before weaving, which would reduce the friction resistance and temperature during twisting and braiding, thereby improving the situation where microcracks are prone to appear on the surface of the steel wire 10. The lubricating liquid used here is the cutting fluid for machine tool metal processing.

[0055] By placing the drip assembly 7 near the wire slider 6, the lubricating liquid can be supplied to the chamber of the filler 703 nearby, and the filler 703 coats the surface of the steel wire 10, thereby reducing the occurrence of micro cracks on the surface of the steel wire 10 during the later twisting and braiding, and improving the service life of the hexagonal mesh. In addition, the drip assembly 7 increases the deadweight of the wire slider 6, preventing the wire slider 6 from vibrating at high frequencies along with the loose steel wire 10.

[0056] Specifically, the guide assembly also includes a push rod 705, a valve plate 706 and a compression spring 708. The liquid outlet pipe 7021 is horizontally fixedly connected to the bottom of the liquid storage tank 702, and the liquid outlet pipe 7021 is welded on the side wall of the bottom of the liquid storage tank 702. The inner end of the liquid outlet pipe 7021 is set as a liquid outlet slope with a lower front and a higher rear. The valve plate 706 is tiltedly set in the cavity of the liquid storage tank 702, and the top pin of the valve plate 706 is connected to the inner rear side wall of the liquid storage tank 702. The bottom end of the valve plate 706 can be attached to and closed. The push rod 705 is horizontally sealed and guided on the rear side wall of the liquid storage tank 702 through the sealing sleeve 704, that is, the push rod 705 can be guided and slid in the hole of the sealing sleeve 704. The compression spring 708 is sleeved on the push rod 705 and can push the push rod 705 backward. The compression spring 708 is connected with a compression spring sleeve 707. The compression spring sleeve 707 is installed on the rear side wall of the liquid storage tank 702 through flange screws. The two ends of the compression spring 708 are respectively abutted on the rear side wall of the liquid storage tank 702 and the ring platform at the rear end of the push rod 705. The rear end head of the push rod 705 abuts on the side wall of the front support plate 5. The front end head of the push rod 705 located in the cavity of the liquid storage tank 702 can push the valve plate 706 forward, so that the bottom end of the valve plate 706 temporarily leaves the liquid outlet slope, and the liquid outlet pipe 7021 discharges the lubricating liquid. A bridge-shaped protrusion 504 is provided on the side wall of the front support plate 5, and a slide rail groove 503 is provided above each slide rail groove 503. The rear end head of the push rod 705 can pass over the bridge-shaped protrusion 504. Once the bridge-shaped protrusion 504 passes, the push rod 705 pushes the valve plate 706 once.

[0057] Specifically, if Figure 4As shown, a rubber pad is compounded on the bottom wall of the valve plate 706 that is attached to close the liquid outlet slope, and a counterweight is welded on the side wall of the bottom end of the valve plate 706 that is away from the rubber pad.

[0058] Through the cooperation of the push rod 705 and the bridge-shaped protrusion 504, as the guide plate drives the steel wire 10 from one end of the spring-setting machine to the other end, the wire slider 6 will also be driven from one end of the slide rail groove 503 to the other end in one stroke, so that the rear end of the push rod 705 can pass over the bridge-shaped protrusion 504 once, the push rod 705 pushes the valve plate 706 once, the bottom end of the valve plate 706 briefly leaves the liquid outlet slope once, and the liquid outlet pipe 7021 outputs a stream of lubricating liquid to the filler 703, ensuring that the filler 703 is continuously infiltrated with the lubricating liquid and is evenly coated on the surface of the steel wire 10. In addition, when the equipment is suspended, the wire slider 6 stops at a position outside the bridge-shaped protrusion 504, and the liquid outlet slope is in a state of being closed by the valve plate 706, avoiding the waste of lubricating liquid during the downtime period. By welding a counterweight to the side wall of the bottom end of the valve plate 706 facing away from the rubber pad, the rubber pad can effectively seal the liquid outlet slope under the deadweight pressure of the valve plate 706 and the counterweight.

[0059] The working process of the metal mesh wire feeding rack of the present invention is as follows: the four wire storage racks 8 arranged below the bracket body 1 respectively guide the steel wires 10 upward, and the steel wires 10 pass through the square opening area between the guard plate group and the guard arm group, and are bent forward on the transverse roller shaft 2 and conveyed to the front support plate 5. Two steel wires 10 are bent and conveyed on each transverse roller shaft 2, and synchronously drive the transverse roller shaft 2 to rotate. The steel wires 10 conveyed forward pass through the guide hole 601 in the middle of the wire slider 6, and the steel wires 10 are coated with lubricating liquid when passing through the filler 703. The steel wires 10 continue to be conveyed forward to the guide plate of the spring punching machine, and the four steel wires 10 are correspondingly guided by four wire sliders 6 of different heights to the four wire entry stations of the guide plate with staggered heights. The guide plate will reciprocate left and right when performing the spring punching operation, and will also drive the wire slider 6 to reciprocate in the slide rail groove 503. As the guide plate drives the steel wire 10 from one end of the spring-making machine to the other end, it will also drive the wire slider 6 from one end of the slide rail groove 503 to the other end in one stroke, so that the rear end head of the push rod 705 can pass over the bridge-shaped protrusion 504 once, the push rod 705 pushes the valve plate 706 once, and the bottom end of the valve plate 706 briefly leaves the liquid outlet slope once, and the liquid outlet pipe 7021 outputs a stream of lubricating liquid through the liquid guide channel 602 to the upper part of the trumpet mouth where the filler 703 is located, ensuring that the filler 703 is continuously infiltrated with the lubricating liquid and is evenly coated on the surface of the steel wire 10.

[0060] In summary, the metal mesh wire feeder of the present invention can rotate with the cross roller shaft 2 while bending and guiding the steel wire 10, which greatly reduces the sliding friction resistance and avoids scratching the surface of the steel wire 10; the steel wire 10 is laterally limited by the edge 301 of the protective plate 3, which reduces the contact between adjacent steel wires 10, thereby reducing the winding of the steel wire 10; through the arrangement of the front support plate 5 and the guide assembly, each steel wire 10 can be guided and spaced above the front side wall of the bracket body 1, and mutual interference between them is avoided. The metal mesh wire feeder of the present invention uses a cross roller shaft and a front support plate to guide and convey the steel wire, which reduces the winding and knotting of the steel wire and improves the efficiency of the spring making operation. In addition, by setting two transverse roller shafts 2 with staggered heights, more than two of the disc guard groups are set on each transverse roller shaft 2 to guide the steel wire 10, so that the height space can be fully utilized to separate each steel wire 10, and the wire entry position of the guide plate of the spring-making machine is also staggered, that is, it has good adaptability with the guide plate. The sleeve portion can be slidably sleeved on the transverse roller shaft 2 and locked by the first top wire 302, that is, the adjustment of the opening size of the disc guard group is realized, which is suitable for the release of steel wire storage racks 8 of different sizes. In other words, the transverse roller shaft 2, the disc edge 301, the support arm 902 and the square tube crossbeam 4 enclose a closed square opening area, and the steel wire 10 passes through the square opening area. Even if the steel wire 10 is too loose when it is led out from the steel wire storage rack 8, it will not detach from the square opening area, thus avoiding the contact and interference between adjacent steel wires 10. At the same time, the arm guard 9 is also sleeved on the square tube crossbeam 4 through the square tube sleeve 901, which can move axially, so that the disc guard group with different opening sizes can be adapted. The protrusion is inserted into the annular groove to completely close the straight seam gap between the arm 902 and the disc edge 301, so that even if the thinner wire 10 is released, it will not escape from the square mouth area. The four groups of guide components arranged in a staggered manner in height and left and right are used to guide between the horizontal roller shaft 2 and the guide plate of the spring beating machine, which has good adaptability and spacing, and minimizes the mutual interference between the steel wires 10. Through the vertical guide cooperation of the vertical sleeve 102 and the vertical rod 501, the height of the front support plate 5 can be adjusted as a whole, and it is convenient to remove or lower the front support plate 5 as a whole to carry out maintenance of the guide component. By sliding the wire slider 6 left and right in the slide rail groove 503, the applicability of the left and right reciprocating movement of the guide plate of the spring beating machine can be adjusted, and the left and right bending angles of the steel wire 10 can be reduced. By placing the drip assembly 7 near the wire slider 6, the lubricating liquid can be supplied to the chamber of the filler 703 nearby, and the filler 703 coats the surface of the steel wire 10, thereby reducing the occurrence of micro cracks on the surface of the steel wire 10 during the later twisting and braiding, and improving the service life of the hexagonal mesh. In addition, the drip assembly 7 increases the deadweight of the wire slider 6, preventing the wire slider 6 from vibrating at high frequencies along with the loose steel wire 10.Through the cooperation of the push rod 705 and the bridge-shaped protrusion 504, as the guide plate drives the steel wire 10 from one end of the spring-setting machine to the other end, the wire slider 6 will also be driven from one end of the slide rail groove 503 to the other end in one stroke, so that the rear end of the push rod 705 can pass over the bridge-shaped protrusion 504 once, the push rod 705 pushes the valve plate 706 once, the bottom end of the valve plate 706 briefly leaves the liquid outlet slope once, and the liquid outlet pipe 7021 outputs a stream of lubricating liquid to the filler 703, ensuring that the filler 703 is continuously infiltrated with the lubricating liquid and is evenly coated on the surface of the steel wire 10. In addition, when the equipment is suspended, the wire slider 6 stops at a position outside the bridge-shaped protrusion 504, and the liquid outlet slope is in a state of being closed by the valve plate 706, avoiding the waste of lubricating liquid during the downtime period. By welding a counterweight to the side wall of the bottom end of the valve plate 706 facing away from the rubber pad, the rubber pad can effectively seal the liquid outlet slope under the deadweight pressure of the valve plate 706 and the counterweight.
