Description

Technical Field

[0001] This utility model belongs to the field of coil nail production, and in particular, a fully automatic coil nail production line. Background Technology

[0002] Coil rivets consist of a group of identical, equidistantly arranged individual nails and connectors. The connectors can be made of copper-plated iron wire, etc. The connectors connect to the nails, stringing them together and then rolling them into a coil. Threaded coil rivets are popular due to their high strength and resistance to bending, and as a commonly used production part, they are widely used in industry with huge demand. The production process typically involves first using a nail-making machine to form nails from coiled steel wire, then using a thread-rolling machine to roll the threads onto the nails, followed by a coiling machine connecting the nails to the connectors to form a coil rivet, and finally sending the coil rivet to a rubber band-attaching machine to complete the coil rivet production. In the current coil rivet production process, each of these steps is performed separately, with manual handling in between. This process is time-consuming and labor-intensive, resulting in high worker fatigue and low production efficiency, failing to meet demand. Furthermore, existing coil rivets are not resistant to long-term storage and are prone to rusting, affecting their subsequent use. Utility Model Content

[0003] To overcome the shortcomings of the existing products mentioned above, this utility model provides a fully automated production line for coil nails that has a high production speed and can automatically paint the coil nails.

Next to the main nail conveyor line 1, several nail making machines 10 are arranged. The output end of the nail making machine 10 is connected to the main nail conveyor line 1 through the first conveyor line 11 for feeding material onto the main nail conveyor line 1. The first magnetic lifting conveyor line 2 and the second magnetic lifting conveyor line 4 have the same structure, including a frame 21 and a rotary chain magnetic suction device 25 driven by a motor and tilted on the frame 21. Each link of the rotary chain magnetic suction device 25 is provided with a bar permanent magnet 26. On the frame 21, close to the outside of the rotary chain magnetic suction device 25, a metal plate 22 covering the rotary chain magnetic suction device is fixedly installed. Closely matching the metal plate 22, a vibrating feed hopper 23 for feeding is provided next to the bottom of the metal plate 22, and next to the top of the metal plate 22... A scraper discharge trough 24 for discharging material is provided on one side. The vibrating feed hopper 23 and the scraper discharge trough 24 are located on different sides of the metal plate 22. The nails can be continuously attracted from the vibrating feed hopper 23 to the outer surface of the metal plate 22 by the magnetism generated by the rotary chain magnetic attraction device 25. When the rotary chain magnetic attraction device 25 rotates, it carries the nails and lifts them up along the outer surface of the metal plate 22. When the nails are lifted to the highest point of the metal plate 22 and continue to move forward, the scraping action of the scraper discharge trough 34 can scrape the nails off the outer surface of the metal plate, thus achieving smooth material discharge.

The tops of the two vertical rods 78 are also connected by a connecting plate 79. The width of the connecting plate 79 is greater than the width of the vertical guide groove 77, so that the pressure roller 75 can be raised by lifting the connecting plate 79 for quick material feeding. When painting is required, the pressure roller 75 presses onto the paint roller 74 by its own weight to achieve automatic painting of the coil nails.

Through the magnetism generated by the rotary chain magnetic attraction device 25, the nails can be continuously attracted from the vibrating feed hopper 23 to the outer surface of the metal plate 22. When the rotary chain magnetic attraction device 25 rotates, it carries the nails upwards along the outer surface of the metal plate 22. When the nails are lifted to the highest point of the metal plate 22 and continue to move forward, the scraping action of the scraper discharge trough 34 can scrape the nails off the outer surface of the metal plate, thus achieving smooth material discharge.

[0019] The high-frequency coil heating device 6 is a high-frequency heating coil.

[0020] The automatic paint coating and even coating device 7 includes a paint coating mechanism 71 located at the front and a paint even coating mechanism 72 located at the rear.

Above the paint coating roller 74, there is also a pressure roller 75 whose height and position are adjustable and can cooperate with it.

[0021] The inner wall of the paint tank 73 has two symmetrical support bars 76 with vertical guide grooves 77. The two ends of the paint roller 74 are rotatably mounted on the bottom of the two vertical guide grooves 77 of the two support bars 76.

The tops of the two vertical rods 78 are also connected by a connecting plate 79. The width of the connecting plate 79 is greater than the width of the vertical guide groove 77, so that the pressure roller 75 can be raised by lifting the connecting plate 79 to facilitate material feeding. When paint is needed, the pressure roller 75 presses onto the paint roller 74 by its own weight to achieve automatic painting of the coil nails.

[0028] Production process: In the production of coiled nails, each nail-making machine 10 first uses steel wire coils to form nails. The formed nails are then collected and transported to the main nail conveyor line 1 via the first conveyor line 11. The main nail conveyor line 1 then transports the nails to the vibrating feed hopper 23 of the first magnetic lifting conveyor line 2. The lifting function of the first magnetic lifting conveyor line 2 then smoothly feeds the nails into the feed port of the thread rolling machine 3, i.e., the vibrating feeding mechanism 31 of the thread rolling machine. The thread rolling machine 3 then rolls the nails with threads. After the thread rolling is completed, the nails are then transported to the main feed hopper 23 of the first magnetic lifting conveyor line 2. The nails are smoothly fed into the feeding port of the nail coiling machine 5, i.e., the vibrating feeding mechanism 51 of the nail coiling machine, by the lifting function of the second magnetic lifting conveyor line 4. Then, the nail coiling machine 5 sorts and welds the nails onto the connector to form nail coils. The nail coils are then heated by the high-frequency coil heating device 6 and then automatically coated and evenly coated by the automatic paint coating and paint spreading device 7. Finally, after the tension is adjusted by the tension adjusting device 8, the material is fixed by the rubber band wrapping and unloading device 9 before being unloaded, thus completing the production of the nail coils.

[0029] Therefore, it can be seen that the fully automatic coil nail production line of this utility model has an ingenious structure, which can realize the simultaneous feeding of materials to the back end by multiple nail making machines, and the nails can flow quickly and smoothly between the various equipment at different heights. This allows the high-speed thread rolling machine, coil nail machine, and coiled rubber band feeding device to operate efficiently and continuously, greatly improving the overall production efficiency of coil nails. In particular, the addition of an automatic paint coating and even coating device allows the coil nails to be automatically painted before feeding, improving their anti-corrosion performance. Furthermore, the painting is done after passing through a high-frequency coil heating device, which can further improve the paint adhesion, enhance their rust prevention ability, broaden their application range, extend their undamaged preservation time, and make the equipment easier to maintain. It is highly practical and worthy of promotion.
