Description

Technical Field

[0001] This utility model relates to the technical field of nail making machine wire feeding mechanism, specifically a nail making wire feeding buffer and speed stabilization mechanism. Background Technology

[0002] As the construction, furniture, and hardware industries continue to demand higher quality and production efficiency for nail products, upgrading the performance of nail-making equipment has become a key aspect of industry development. It directly determines the continuity, stability, and finished product qualification rate of the nail-making process. Wire piling or speed fluctuations during the wire feeding process can directly lead to production line shutdowns, scrapped finished products, and even increased equipment maintenance costs.

[0003] A Chinese patent with publication number CN222058716U discloses a wire feeding mechanism for a nail-making machine. This mechanism adjusts the mounting height of the mounting frame on the support frame according to the mechanism's installation position within the nail-making machine. A motor drives a lead screw to rotate, thereby adjusting the relative movement of two sets of moving blocks. This allows for synchronous adjustment of the two mounting seats and the position of the wire feeding wheels, ensuring that the center point of wires of different diameters is aligned, facilitating wire feeding at the nail-making machine's processing area. The wire can pass through the wire feeding hole and then be conveyed between the wire feeding wheels, ensuring that the center point of wires of different diameters is aligned, thus facilitating wire feeding at the nail-making machine's processing area. The wire feeding blocks assist in conveying the wire to the wire feeding wheels. A spring allows the wire feeding blocks to float according to the wire's feeding position. The mounting frame is easily adjustable on the support frame, allowing for adjustment based on the mechanism's installation position within the nail-making machine.

[0004] In the aforementioned literature, the existing nail-making machine wire feeding mechanism is prone to stretching deformation or breakage due to excessive tension on the nail-making wire, resulting in poor wire feeding stability. Furthermore, the vibration during equipment operation can cause fluctuations in the wire feeding speed of the wire feeding wheel, leading to wire accumulation or untimely wire feeding, resulting in unstable wire feeding speed, which in turn can affect product quality and damage the equipment. Therefore, a nail-making wire feeding buffer and speed stabilization mechanism is proposed to address the above problems. Utility Model Content

[0005] To overcome the shortcomings of existing technologies, and to address the problems of poor wire feeding stability and the inability to monitor and adjust the wire feeding speed, which easily leads to speed fluctuations and affects normal production, this utility model proposes a nail-making wire feeding buffer and speed stabilization mechanism.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: The nail making wire feeding buffer speed stabilizing mechanism of this utility model includes a base, a sliding seat is slidably arranged on the base, a fixed plate is fixed on the sliding seat, a plurality of support shafts are horizontally arranged and rotatably installed on the side of the fixed plate, a drive wheel is fixedly connected to the end of each of the plurality of support shafts, an infrared speed measuring instrument is fixed on the side of the fixed plate, and the working end of the infrared speed measuring instrument is directly facing the rotation surface of one of the drive wheels.

[0007] The sliding seat has multiple tension springs on one side facing the wire feeding direction. A drive shaft is rotatably mounted on the side of the fixed plate. A drive disk is fixedly connected to the end of the drive shaft. Rollers are evenly distributed on the curved surface of the side of the drive disk, and the central axis of each roller is perpendicular to the center line of the drive disk. The drive shaft is connected to multiple support shafts via belts.

[0008] The sliding seat has two sliders that are raised and lowered. A rotating shaft is rotatably mounted between the two sliders. A spline shaft is fixed on the rotating shaft and located between the two sliders. A conical block is slidably engaged on the spline shaft. The centerline of the conical block is parallel to the centerline of the transmission disk and located directly below the transmission disk. The conical surface of the conical block is in contact with the roller located on the lower side of the transmission disk.

[0009] Preferably, the fixed plate has a sliding groove on its side, and a lifting rod is slidably arranged in the sliding groove. Multiple driven wheels are horizontally arranged and rotatably installed on the side of the lifting rod, and the multiple driven wheels are respectively arranged above multiple driving wheels. A threaded sleeve is fixed through the fixed plate, and a lead screw is threaded through and connected to the threaded sleeve. The bottom end of the lead screw is rotatably installed on the lifting rod, and a turntable is fixed to the top end of the lead screw.

[0010] Preferably, two upright plates are fixed on the base, and multiple guide rods are horizontally fixed between the two upright plates. The sliding seat is slidably disposed on the multiple guide rods. Multiple tension springs are respectively sleeved on the multiple guide rods, and the active ends of the tension springs are respectively connected to the side wall of the upright plate and the side wall of the sliding seat on the corresponding side.

[0013] Preferably, each slider has a baffle fixed to its top, and each spring is located below the slider.

[0014] Preferably, the end of the rotating shaft is connected to a motor, and the motor is fixed on the slider on the corresponding side.

[0015] The advantages of this utility model are:

[0016] This invention addresses the issue that when the nail-making machine encounters resistance at high speed, the sliding seat slides on the guide rod to the opposite side of the tension spring, pulling the spring to extend. This buffers the change in tension, allowing the nail-making wire to continue to be fed stably. When the wire feeding direction encounters resistance and the wire feeding speed changes, the control terminal adjusts the transmission ratio between the conical block and the transmission disc based on the detection data from the infrared velocimeter to adjust the wire feeding speed, ensuring that the wire feeding speed remains stable within the set range.

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 scope of protection of the present utility model.

[0026] Please see Figure 1-6 As shown, a nail-making wire feeding buffer and speed-stabilizing mechanism includes a base 1, a sliding seat 4 slidably disposed on the base 1, a fixed plate 6 fixed on the sliding seat 4, a plurality of support shafts 28 horizontally arranged and rotatably mounted on the side of the fixed plate 6, a drive wheel 10 fixedly connected to the end of each of the plurality of support shafts 28, and an infrared speed meter 14 fixed on the side of the fixed plate 6, the working end of the infrared speed meter 14 facing the rotation surface of one of the drive wheels 10;

[0027] The sliding seat 4 is provided with multiple tension springs 5 ​​on one side facing the wire feeding direction. The fixed plate 6 is rotatably mounted with a drive shaft 25. The end of the drive shaft 25 is fixedly connected to a drive disk 26. The side surface of the drive disk 26 is rotatably mounted with evenly distributed rollers 27, and the central axis of each roller 27 is perpendicular to the center line of the drive disk 26. The drive shaft 25 is connected to multiple support shafts 28 via belts.

[0028] The sliding seat 4 is provided with two sliders 16 that are raised and lowered. A rotating shaft 18 is rotatably mounted between the two sliders 16. A spline shaft 19 is fixed on the rotating shaft 18 and located between the two sliders 16. A conical block 20 is slidably engaged on the spline shaft 19. The center line of the conical block 20 is parallel to the center line of the transmission disk 26 and is located directly below the transmission disk 26. The conical surface of the conical block 20 is in contact with the roller 27 located on the lower side of the transmission disk 26.

[0029] The fixed plate 6 has a sliding groove 7 on its side, and a lifting rod 8 is slidably arranged in the sliding groove 7. Multiple driven wheels 9 are horizontally arranged and rotatably installed on the side of the lifting rod 8, and the multiple driven wheels 9 are respectively arranged above multiple driving wheels 10. A threaded sleeve 11 is fixed through the fixed plate 6, and a lead screw 12 is threaded through and connected to the threaded sleeve 11. The bottom end of the lead screw 12 is rotatably installed on the lifting rod 8, and a turntable 13 is fixedly connected to the top end of the lead screw 12.

[0030] Two upright plates 2 are fixed on the base 1. Multiple guide rods 3 are horizontally fixed between the two upright plates 2. The sliding seat 4 is slidably disposed on the multiple guide rods 3. Multiple tension springs 5 ​​are respectively sleeved on the multiple guide rods 3. The active end of the tension spring 5 is respectively connected to the side wall of the upright plate 2 and the side wall of the sliding seat 4 on the corresponding side.

[0031] Two uprights 15 are fixedly connected to the sliding seat 4 and below the two sliders 16 respectively, and the sliders 16 are slidably mounted on the two uprights 15 below them. Each upright is fitted with a spring 17.

[0032] One of the sliders 16 has hydraulic rods 21 fixed on its upper and lower sides respectively. The working ends of the hydraulic rods 21 are fixed to a positioning ring 22. A sliding ring 23 is slidably disposed inside the positioning ring 22 and the sliding ring 23 is fixed to the end face of the conical block 20.

[0033] Each slider 16 has a baffle 24 fixedly attached to its top, and each spring 17 is located below the slider 16.

[0034] The end of the rotating shaft 18 is connected to a motor 29, and the motor 29 is fixed on the slider 16 on the corresponding side.

[0035] During operation, the existing nail-making machine's wire feeding mechanism is prone to stretching deformation or breakage due to excessive tension on the nail-making wire, resulting in poor wire feeding stability. Furthermore, the vibration during equipment operation can cause fluctuations in the wire feeding speed of the wire feeding wheel, leading to wire accumulation or untimely wire feeding, resulting in unstable wire feeding speed. This can easily affect product quality and damage the equipment. In this solution, in the initial state, the tension spring 5 will always pull the sliding seat 4 to the side with the same wire feeding direction, so that the sliding seat 4 slides on the guide rod 3 in the wire feeding direction. The spring 17 will always push the slider 16 upward, so that the conical surface of the conical block 20 is in close contact with the rolling surface of the roller 27 located below the transmission disk 26, so as to maintain the drive connection to the transmission disk 26.

[0036] In use, the nail-making wire is passed through multiple driven wheels 9 and multiple drive wheels 10, and the first turntable 13 is rotated. Under the threaded connection between the threaded sleeve 11 and the lead screw 12, the lead screw 12 rotates, causing the lifting rod 8 to slide up and down in the sliding groove 7. This, in turn, causes multiple driven wheels 9 located on the side of the lifting rod 8 to descend, so that the nail-making wire is clamped between the driven wheels 9 and the drive wheels 10 for transport. By controlling the operation of the motor 29, the motor 29 drives the spline shaft 19 through the rotating shaft 18. Under the meshing transmission action of the tapered block 20 and the spline shaft 19, the spline shaft 19 rotates. When the cone block 20 rotates, it drives the transmission disk 26 to rotate through the roller 27. Since the center line of the roller 27 is perpendicular to the transmission disk 26, the roller 27 will not rotate when the cone block 20 and the transmission disk 26 are in transmission, thus ensuring the driving transmission effect. When the transmission disk 26 rotates, it drives the transmission shaft 25 to rotate. When the transmission shaft 25 rotates, it drives multiple support shafts 28 to rotate synchronously through the belt, thereby driving multiple drive wheels 10 to rotate. The wire is fed in the state of clamping the nail wire between the driven wheel 9 and the drive wheel 10, and the wire feeding direction is located on the side of the sliding seat 4 where the tension spring 5 is provided.

[0037] When the nail-making machine encounters resistance while operating at high speed, the instantaneous tension of the nail-making wire increases, and the direction of resistance is opposite to the direction of wire feeding. Due to the clamping and conveying of the nail-making wire by the driven wheel 9 and the drive wheel 10, the sliding seat 4 will slide on the guide rod 3 to the side opposite to the tension spring 5 and pull the tension spring 5 to extend, thereby buffering the change in tension. When the resistance disappears, the tension spring 5 will contract and return to its original state, pulling the sliding seat 4 to reset, so that the nail-making wire can continue to be fed stably.

[0038] When the wire feeding direction encounters resistance and the wire feeding speed changes, the rotational speed of the drive wheel 10 decreases while the driven wheel 9 and drive wheel 10 are clamping the nail-holding wire. The rotational speed of the drive wheel 10 is detected in real time by the infrared tachometer 14. When the rotational speed of the drive wheel 10 fluctuates, the control terminal adjusts the transmission ratio between the conical block 20 and the transmission disk 26 based on the detection data from the infrared tachometer 14. This is achieved by controlling the extension and retraction of the hydraulic rod 21. When the hydraulic rod 21 extends and retracts, it causes the conical block 20 to slide on the spline shaft 19. As the conical block 20 slides, it causes the roller 27 that is in contact with it to roll, thereby adjusting the transmission position between the transmission disk 26 and the conical block 20. When the conical block 20 moves to the opposite side of the transmission disk 26, the transmission ratio between the conical block 20 and the transmission disk 26 decreases, thereby reducing the rotational speed of the drive wheel 10 and the driven wheel 9 so that the front-end nail-making wire is cut off to eliminate resistance. Conversely, when the transmission ratio between the conical block 20 and the transmission disk 26 increases, the rotational speed of the drive wheel 10 and the driven wheel 9 increases to increase the wire feeding speed, ensuring that the wire feeding speed is always stable within the set range, thus ensuring the stability of the nail-making process and the quality of the nail. When the conical block 20 moves, the slider 16 is squeezed upward under the action of the spring 17 to maintain the transmission action between the conical block 20 and the transmission disk 26.

[0039] It effectively achieves the function of feeding wire in a nail-making machine, and can adjust the resistance changes and wire feeding speed fluctuations in real time during the wire feeding process, thereby improving processing accuracy and product quality.
