Description

Technical Field

[0001] This utility model relates to the field of wire technology, specifically a wire surface coating device. Background Technology

[0002] Electrical wires are conductors that transmit electrical energy. They are classified into bare wires, magnetized wires, and insulated wires. Bare wires have no insulation layer and include copper and aluminum flat wires, overhead stranded wires, and various profiles. They are mainly used in outdoor overhead lines and indoor busbars and switch boxes. Magnetized wires are insulated conductors that generate a magnetic field when energized or induce a current in a magnetic field. They are mainly used in motor and transformer windings and other related electromagnetic equipment.

[0003] Utility model patent CN211757062U provides a wire powdering machine, including a horizontally arranged outer cylinder and an inner cylinder. The inner cylinder contains a high-frequency vibration unit and is located within the outer cylinder. A filling layer filled with a highly elastic material is provided between the inner and outer cylinders. This utility model has a simple structure. The cable passing through the inner cylinder vibrates along with the inner cylinder, causing talcum powder trapped between the wire cores to fall off. The talcum powder is then adsorbed by an electrostatic dust removal mesh. After the process is completed, a suction fan operates to clean away the talcum powder.

[0004] To improve the efficiency of wire production, a layer of powder is sprayed onto the surface of the wire to prevent it from sticking together. Although the powder coating machine in the aforementioned patent can perform powder coating on the wire, the amount of wire coated at one time is small, which reduces the efficiency of wire coating. Therefore, we provide a wire surface powder coating device to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a device for coating the surface of electrical wires to solve the problems mentioned in the prior art.

[0007] Preferably, the surface of the toner box is provided with a wire threading port, and two sets of support rollers are rotatably connected inside the toner box. The support rollers are located on the upper and lower sides of the wire threading port. The support rollers reduce the friction between the wire and the wire threading port and improve the stability of wire transmission.

[0008] Preferably, a negative pressure pump is fixedly connected to the surface of the powder-passing box, and the output end of the negative pressure pump is located at the bottom of the powder-passing box. The output end of the negative pressure pump is fixedly connected to the dryer. The negative pressure pump extracts the talc powder from the bottom of the powder-passing box and dries the talc powder through the dryer, thereby improving the stability of the powder-passing process for wires.

[0009] Preferably, the output end of the dryer is fixedly connected to a conveying pipe, the top end of the conveying pipe passes through the powder box and is fixedly connected to the conveying chamber, and the conveying pipe is fixedly connected to the powder box. Through the conveying pipe, the talc powder inside the dryer is conveyed to the conveying chamber.

[0010] Preferably, a telescopic sleeve is fixedly connected to the surface of the vibration frame, and the top end of the telescopic sleeve is fixedly connected to the lifting plate. A telescopic spring is sleeved on the outside of the telescopic sleeve, and the two ends of the telescopic spring are fixedly connected to the vibration frame and the lifting plate respectively. Through the telescopic spring, the vibration frame is driven to vibrate up and down, shaking off excess talcum powder from the surface of the wire.

[0011] Preferably, a limiting slide rod is fixedly connected to the surface of the lifting plate, and a fixed slide frame is slidably connected to the surface of the limiting slide rod.

The power shaft is rotatably connected to the powder conveying box and is fixedly connected to an eccentric rod. The electric motor controls the rotation of the power shaft, thereby driving the eccentric rod to rotate.

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

[0015] 1. This application uses a conveying bin and a powder spraying head to spray talc powder onto the surface of the wire. The conveying bin can wrap the wire in all directions, so that the talc powder is evenly and comprehensively sprayed onto the surface of the wire. The talc powder is dried by a dryer to prevent it from getting damp and clumping, thereby improving the powdering effect on the wire. The two sliding rollers are fixed by a vibrating frame. The lifting plate moves up and down, causing the vibrating frame to drive the sliding rollers to vibrate, which prevents too much talc powder from adhering to the surface of the wire and improves the stability of the powdering process.

[0016] 2. This application facilitates the transmission of electrical wires through the wire threading port. The support roller reduces friction between the wire and the wire threading port, improving the stability of wire transmission. The negative pressure pump extracts talcum powder from the bottom of the powder box and dries it through a dryer, improving the stability of wire powder transmission. The dried talcum powder is then transported to the conveying chamber through a conveying pipe, improving the stability of talcum powder spraying. The telescopic sleeve limits the vertical movement of the vibrating frame, improving the stability of the vertical sliding of the vibrating frame.

[0017] 3. This application uses a telescopic spring to provide thrust to the vibrating frame, causing the vibrating frame to vibrate up and down, shaking off excess talcum powder and improving the efficiency of powder passing through the wire. By fixing the slide frame, the limiting slide rod is fixed, making the movement of the lifting plate more stable. By rotating the eccentric rod, the sliding block controls the up and down sliding of the power frame, thereby controlling the up and down movement of the lifting plate. By controlling the rotation of the power shaft through the motor, the eccentric rod is driven to rotate. Attached Figure Description

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] like Figure 1 - Figure 4 As shown, this utility model provides a technical solution for a wire surface powdering device, including a powdering box 1. The surface of the powdering box 1 is provided with a wire threading port 2. Two sets of support rollers 3 are rotatably connected inside the powdering box 1, and the support rollers 3 are located on the upper and lower sides of the wire threading port 2. The wire is conveniently transmitted through the wire threading port 2, and the friction between the wire and the wire threading port 2 is reduced by the support rollers 3, thereby improving the stability of wire transmission.

[0025] The powder coating box 1 is equipped with a powder spraying mechanism 4. The powder spraying mechanism 4 includes a conveying chamber 401 and a dryer 405 that are fixedly connected to the powder coating box 1. The inner wall of the conveying chamber 401 is fixedly connected with powder spraying heads 402 arranged at equal intervals. Through the conveying chamber 401 and the powder spraying heads 402, talc powder is sprayed onto the surface of the wire. The conveying chamber 401 can wrap the wire in all directions, so that the talc powder is evenly and in all directions sprayed onto the surface of the wire. The dryer 405 dries the talc powder to prevent it from getting damp and clumping, thereby improving the powder coating effect of the wire.

[0026] A negative pressure pump 403 is fixedly connected to the surface of the powder-passing box 1, and the output end of the negative pressure pump 403 is located at the bottom of the powder-passing box 1. The output end of the negative pressure pump 403 is fixedly connected to the dryer 405. The negative pressure pump 403 extracts the talc powder at the bottom of the powder-passing box 1 and dries the talc powder through the dryer 405 to improve the stability of the powder-passing of the wire.

[0027] The output end of the dryer 405 is fixedly connected to the conveying pipe 404. The top end of the conveying pipe 404 passes through the powder box 1 and is fixedly connected to the conveying chamber 401. The conveying pipe 404 is fixedly connected to the powder box 1. The talc powder is dried by the dryer 405 and then conveyed to the inside of the conveying chamber 401 through the conveying pipe 404, thereby improving the stability of talc powder spraying.

[0028] The powder-passing box 1 is equipped with a vibration mechanism 5, which includes a vibration frame 501 and a lifting plate 503. The vibration frame 501 is rotatably connected to two sliding rollers 502. The vibration frame 501 fixes the two sliding rollers 502. The lifting plate 503 moves up and down, causing the vibration frame 501 to drive the sliding rollers 502 to vibrate, thus avoiding excessive talcum powder adhering to the surface of the wire and improving the stability of the powder-passing process.

[0029] A telescopic sleeve 504 is fixedly connected to the surface of the vibrating frame 501, and the top end of the telescopic sleeve 504 is fixedly connected to the lifting plate 503. A telescopic spring 505 is sleeved on the outside of the telescopic sleeve 504, and the two ends of the telescopic spring 505 are fixedly connected to the vibrating frame 501 and the lifting plate 503 respectively. The telescopic sleeve 504 limits the up and down movement of the vibrating frame 501, thereby improving the stability of the up and down sliding of the vibrating frame 501. The telescopic spring 505 provides a thrust to the vibrating frame 501, causing the vibrating frame 501 to vibrate up and down, thereby shaking down excess talcum powder and improving the efficiency of powdering the wire.

[0030] A limiting slide rod 511 is fixedly connected to the surface of the lifting plate 503. A fixed slide 512 is slidably connected to the surface of the limiting slide rod 511, and the top of the fixed slide 512 is fixedly connected to the powder box 1. The limiting slide rod 511 is fixed by the fixed slide 512, so that the limiting slide rod 511 drives the lifting plate 503 to move up and down more stably.

[0031] A power frame 506 is fixedly connected to the surface of the lifting plate 503. A sliding block 507 is slidably connected inside the power frame 506. An eccentric rod 508 is rotatably connected to the surface of the sliding block 507. By rotating the eccentric rod 508, the sliding block 507 controls the power frame 506 to slide up and down, thereby controlling the lifting plate 503 to move up and down.

[0032] An electric motor 510 is fixedly connected inside the powder conveying box 1. A power shaft 509 is fixedly connected to the output end of the electric motor 510. The power shaft 509 is rotatably connected to the powder conveying box 1 and is fixedly connected to the eccentric rod 508. The electric motor 510 controls the rotation of the power shaft 509, which in turn drives the eccentric rod 508 to rotate.

[0033] The negative pressure pump 403, dryer 405 and motor 510 are existing technologies, and their detailed parameters and models will not be described in detail in this application.

[0034] In use, this invention facilitates the transmission of wires via the threading port 2 and support roller 3. A negative pressure pump 403 extracts talc powder from the bottom of the powder-passing box 1, which is then dried by a dryer 405. The conveying pipe 404 transports the talc powder to the conveying chamber 401, where it is sprayed onto the surface of the wire via a powder spraying head 402. The conveying chamber 401 can completely enclose the wire, ensuring even and comprehensive spraying of the talc powder. A motor 510 controls the rotation of the power shaft 509, and an eccentric rod 508 controls the rotation of the sliding block 507, causing the power frame 506 to move the lifting plate 503 up and down. A telescopic spring 505 provides thrust to the vibrating frame 501, causing it to vibrate up and down, dislodging excess talc powder from the wire surface and improving powder-passing efficiency. Multiple wires can be transmitted through the threading port 2, allowing the device to simultaneously perform powder-passing operations on multiple wires, improving wire production efficiency and preventing surface adhesion during production, thus enhancing the stability of wire production.
