Description

Technical Field

[0001] This utility model belongs to the field of coil nail production, and in particular, it relates to an automatic painting device for coil nails. Background Technology

[0002] Coil rivets consist of a group of individual nails of the same shape arranged at equal intervals and a connector. The connector can be made of copper-plated iron wire, etc. The connector connects to each nail, stringing the nails together and then rolling them into a coil. Among coil rivets, threaded coil rivets are popular due to their high strength and resistance to bending. As a commonly used production part, they are widely used in industry and in 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 on the nails, followed by a coil rivet machine connecting the nails to the connector to form a row of nails. Finally, the row of nails is sent to a rubber band-attaching machine to form coil rivets, completing the manufacturing process. However, coil rivets produced in this way are not durable for long-term storage and are prone to rusting, affecting their subsequent use. Utility Model Content

That is, unless specifically stated otherwise, each feature is merely one example of a series of equivalent or similar features.

[0016] like Figure 1-6As shown, the automatic painting device for coil nails is installed after the coil nail machine 50 and before the coiled material sleeve rubber band feeding device. It includes a high-frequency coil heating device 60 and an automatic paint coating and even painting device 70 arranged in sequence. The feeding end of the high-frequency coil heating device 60 is connected to the discharging end of the coil nail machine 50, and the discharging end of the high-frequency coil heating device 60 is connected to the feeding end of the automatic paint coating and even painting device 70. The automatic paint coating and even painting device 70 includes a painting mechanism 71 arranged in front and a paint even painting mechanism 72 arranged in the rear. The painting mechanism 71 includes a paint tank 73 and a painting roller 74 rotatably arranged above the paint tank 73. Above the painting roller 74, there is also a pressure roller 75 with adjustable height that can cooperate with it.

[0017] The high-frequency coil heating device 60 is a high-frequency heating coil.

[0018] 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 two ends of the pressure roller 75 are rotatably connected to a vertical rod 78. The vertical rod 78 can be vertically inserted into the vertical guide groove 77. 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.

[0019] The paint spreading mechanism 72 includes a paint receiving trough 81 and a paint spreading roller 82 rotatably disposed above the paint receiving trough 81. The roller passes under the paint spreading roller 81 to achieve automatic paint spreading.

[0020] Above the automatic paint coating and even coating device 70, there is also a liftable protective cover 83. The top surface of the protective cover 83 is provided with at least one fan 84 that can blow air into the protective cover 83. The side of the protective cover 83 is provided with several ventilation holes 85. By blowing air into the coil nail, the drying speed of the paint on the coil nail can be accelerated.

[0024] Production process: After the nail coiling machine 50 produces a row of nails by vibrating, sorting, and welding the nails to the connectors, the row of nails is first fed into the high-frequency coil heating device 60 for heating. The heated row of nails is then quickly fed into the automatic paint coating and even coating device 70 for automatic paint coating and even coating, thus completing the paint coating of the row of nails. Finally, the painted coiled nails are tensioned by the tension adjusting device 80 and then fixed by the rubber band unloading device before being unloaded, thus completing the overall production of the coiled nails.

[0025] During the painting process, the nails pass sequentially through the painting mechanism 71 and the paint spreading mechanism 72 located behind it. Specifically, they pass between the painting roller 74 and the pressure roller 75 and below the paint spreading roller 82. While painting, the fan above the protective cover blows air onto the nails to make them dry quickly.

[0026] Before the initial painting production begins, the pressure roller 75 is lifted by the connecting plate 79, and then the material is threaded through the nail rack.

[0027] Therefore, the automatic painting device for coiled nails of this utility model has an ingenious structure. By adding an automatic painting and leveling device after the coiling machine and before the coiled material and rubber band feeding device, the coiled nails can be automatically painted before feeding, greatly improving their corrosion resistance. The painting speed is fast and the paint is even. Furthermore, the high-frequency coil heating device further enhances paint adhesion and strengthens the overall rust resistance of the coiled nails, making them more versatile and extending their shelf life. In addition, the cleverly designed adjustment structure of the pressure rollers ensures structural simplicity while facilitating easy feeding of the coiled nails into the automatic painting and leveling device. The protective cover with a top fan and side ventilation holes on the automatic painting and leveling device allows the coiled nails to dry quickly after painting, improving production efficiency. The equipment is also easier to maintain, highly practical, and worthy of promotion.
