Description

Technical Field

[0001] This utility model relates to the field of automatic wire feeding technology, specifically an automatic wire feeding device for a nail making machine. Background Technology

[0002] Automatic wire feeding devices generally consist of multiple sets of lower guide wheels and upper guide wheels. When the wire enters the wire feeding device, the wire passes between the lower guide wheels and the upper guide wheels to guide the wire. However, existing devices have certain drawbacks. For example, the wire feeding mechanism for a nail making machine described in announcement number CN222058716U includes a base plate, a mounting frame, and a support column connected to the top of the base plate. The top of the base plate is provided with a support frame for fixing the mounting frame. Two sets of mounting seats are slidably arranged on one side of the mounting frame. Several wire feeding wheels are rotatably mounted on the side of the mounting seats away from the mounting frame. The ends of the mounting seats are connected to the mounting frame through sliding parts.

[0003] Although the above-mentioned device can drive the movement of several wire feeding wheels installed on it, and the wire feeding wheels on the two sets of mounting bases cooperate to make the center point of steel wires of different diameters consistent, which is beneficial to the wire feeding of the nail making machine, impurities are easily adhered to the surface of the steel wire when it is placed. When the steel wire with impurities passes through the wire feeding roller, it will generate greater friction and may even cause wire jamming, affecting the wire feeding efficiency. Utility Model Content

[0004] The purpose of this invention is to provide an automatic wire feeding device for nail making machines to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An automatic wire feeding device for a nail making machine includes a worktable, a mounting base fixedly connected to the upper surface of the worktable, two conveying seats fixedly connected to the upper surface of the worktable, a servo motor fixedly connected to the front surface of the conveying seats, wire feeding rollers rotatably connected to adjacent surfaces of the two conveying seats, a sliding block slidably connected to adjacent surfaces of the two conveying seats, and a pressure roller rotatably connected to the outer surface of the sliding block.

[0007] A cleaning module is fixedly connected to the side surface of the first mounting base. The cleaning module includes an L-shaped base, a first servo motor, a conveyor roller, and a cleaning belt. The L-shaped base is fixedly connected to the side surface of the first mounting base, the first servo motor is fixedly connected to the side surface of the L-shaped base, the conveyor roller is rotatably connected to the other side surface of the L-shaped base, and there are two of them. The cleaning belt is nested and connected to the outer surface of the conveyor roller.

[0008] Furthermore, an outer sleeve is fixedly connected to the lower surface of the workbench near the four corners, a threaded rod is threaded inside the outer sleeve, a hexagonal column is fixedly connected to the outer surface of the threaded rod, and a wear-resistant seat is fixedly connected to the lower end of the hexagonal column.

[0009] Furthermore, the cleaning module also includes an exhaust fan and a connecting sleeve. The exhaust fan is embedded in the upper surface of the L-shaped base, and the connecting sleeve is fixedly connected to the other side surface of the L-shaped base. A fastening knob is threaded onto the outer surface of the connecting sleeve, and the output end of the first servo motor is fixedly connected to one of the conveying rollers.

[0010] Furthermore, a limiting groove is formed on the outer surface of the conveyor seat, and the slide seat and the limiting groove are slidably connected.

[0011] Furthermore, the number of the wire feeding rollers is multiple, and the output end of the second servo motor is fixedly connected to one of the wire feeding rollers.

[0012] Furthermore, a screw is rotatably connected to the upper surface of the conveyor seat, and a handwheel is fixedly connected to the upper end of the screw, with the handwheel and the slide being threadedly connected.

[0013] Furthermore, an electric push rod is fixedly connected to the upper surface of the workbench, a connecting plate is fixedly connected to the output end of the electric push rod, and a second mounting base is fixedly connected to the side surface of the connecting plate.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. Start the exhaust fan to ventilate and dissipate heat along with the cleaning belt. The output of the No. 1 servo motor drives the conveyor roller to rotate, which in turn drives the cleaning belt. This changes the contact position between the cleaning belt and the steel wire, reducing frictional heat and minimizing its impact. During wire feeding, the two cleaning belts wipe the surface of the steel wire, reducing the amount of debris adhering to the wire surface. The output of the electric push rod moves the connecting plate upward, which in turn moves the No. 2 mounting base upward, changing the distance between the two cleaning modules. This allows the cleaning modules to be used with steel wires of different thicknesses, solving the problem that impurities easily adhere to the surface of the steel wire when it is placed. Steel wires with impurities experience greater friction when passing through the wire feeding roller, which may even cause wire jamming and affect wire feeding efficiency.

[0016] 2. By changing the position of the threaded rod in the outer sleeve under the push of the thread, the device can not only be leveled, but also the overall height of the device can be changed. This allows the center position of the wire cross-section to be adjusted when the device conveys steel wires of different diameters, so that the steel wire can be matched with the wire inlet of the nail making machine.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-5 In this embodiment of the utility model, an automatic wire feeding device for a nail making machine includes a workbench 1. A first mounting base 3 is fixedly connected to the upper surface of the workbench 1. Two conveying seats 5 are fixedly connected to the upper surface of the workbench 1. A second servo motor 502 is fixedly connected to the front surface of the conveying seats 5. Wire feeding rollers 506 are rotatably connected to the adjacent surfaces of the two conveying seats 5. A slide block 504 is slidably connected to the adjacent surfaces of the two conveying seats 5. A lower pressure roller 505 is rotatably connected to the outer surface of the slide block 504.

[0025] A cleaning module 2 is fixedly connected to the side surface of the first mounting base 3. The cleaning module 2 includes an L-shaped base 201, a first servo motor 202, a conveyor roller 207, and a cleaning belt 203. The L-shaped base 201 is fixedly connected to the side surface of the first mounting base 3. The first servo motor 202 is fixedly connected to the side surface of the L-shaped base 201. The conveyor roller 207 is rotatably connected to the other side surface of the L-shaped base 201, and there are two of them. The cleaning belt 203 is nested and connected to the outer surface of the conveyor roller 207. The output end of the first servo motor 202 is fixedly connected to one of the conveyor rollers 207.

[0026] An electric push rod 4 is fixedly connected to the upper surface of the workbench 1. A connecting plate 401 is fixedly connected to the output end of the electric push rod 4. A second mounting base 301 is fixedly connected to the side surface of the connecting plate 401.

[0027] Specifically, there are two cleaning modules 2. The second cleaning module 2 is installed on the side surface of the second mounting base 301. The first servo motor 202 is started, and its output drives the conveyor roller 207 to rotate. The conveyor roller 207 then drives the cleaning belt 203, changing the contact position between the cleaning belt 203 and the steel wire so that it is not limited to a single point, reducing the impact of frictional heat on the cleaning belt 203. During wire feeding, the two cleaning belts 203 wipe the surface of the steel wire, reducing the amount of debris adhering to the surface. The first mounting base 301... Both mounting base 3 and mounting base 301 are used to mount L-shaped base 201. When the electric push rod 4 is started, the output end of the electric push rod 4 drives the connecting plate 401 to move upward, which in turn drives mounting base 301 to move upward. By changing the distance between the two cleaning modules 2, the cleaning module 2 can be adapted to steel wires of different thicknesses. When the second servo motor 502 is started, the output end of the second servo motor 502 drives one of the wire feeding rollers 506 to rotate. The wire feeding roller 506, together with the position-adjustable lower pressure roller 505, clamps and feeds the steel wire, thus completing the automatic wire feeding operation.

[0028] Example 1

[0029] like Figures 1-4 As shown, an outer sleeve 101 is fixedly connected to the lower surface of the workbench 1 near the four corners. A threaded rod 102 is threadedly connected to the inside of the outer sleeve 101. A hexagonal column 103 is fixedly connected to the outer surface of the threaded rod 102. A wear-resistant seat 104 is fixedly connected to the lower end of the hexagonal column 103.

[0030] In this embodiment, by using an external wrench in conjunction with the hexagonal column 103 to rotate the threaded rod 102, the position of the threaded rod 102 in the outer sleeve 101 can be changed under the push of the thread. This not only allows for leveling of the device but also changes the overall height of the device. This makes the center position of the wire cross-section adjustable when the device feeds wires of different diameters, so that the wire can match the wire inlet of the nail making machine.

[0031] like Figures 1-5 As shown, the cleaning module 2 also includes an exhaust fan 204 and a connecting sleeve 205. The exhaust fan 204 is embedded and connected to the upper surface of the L-shaped base 201, and the connecting sleeve 205 is fixedly connected to the other side surface of the L-shaped base 201. A fastening knob 206 is threadedly connected to the outer surface of the connecting sleeve 205.

[0032] In this embodiment, the exhaust fan 204 is activated to perform exhaust operation and dissipate heat along with the cleaning belt 203. For the connecting sleeve 205, an external limiting rod can be placed inside one of the connecting sleeves 205, and the limiting rod is fixed by rotating the fastening knob 206. At this time, the limiting rod and the connecting sleeve 205 on the other cleaning module 2 are slidably connected, guiding the electric push rod 4 when adjusting the spacing of the cleaning modules 2.

[0033] Example 2

[0034] Based on Example 1, in order to overcome the problem of inconvenience in conveying steel wires of different diameters in Example 1.

[0035] like Figures 1-5 As shown, a limiting groove 503 is provided on the outer surface of the conveyor seat 5, the slide seat 504 and the limiting groove 503 are slidably connected, there are multiple wire feeding rollers 506, and the output end of the second servo motor 502 is fixedly connected to one of the wire feeding rollers 506.

[0036] In this embodiment, the slide block 504, in conjunction with the limiting groove 503, is used to limit the up-and-down sliding of the slide block 504. The distribution of the wire feeding roller 506 and the lower pressure roller 505 is as follows: Figure 2 and Figure 3 As shown.

[0037] like Figures 1-5 As shown, a screw 507 is rotatably connected to the upper surface of the conveyor seat 5, and a handwheel 508 is fixedly connected to the upper end of the screw 507. The handwheel 508 and the slide 504 are threaded together.

[0038] In this embodiment, the screw 507 is rotated manually with the handwheel 508. Under the push of the screw, the position of the slide block 504 is changed, and the position of the lower pressure roller 505 is further changed, so that the wire feeding roller 506 and the lower pressure roller 505 can clamp and convey steel wires of different diameters.
