Description

Technical Field

[0001] This application relates to the field of talc powder application equipment, and more particularly to a talc powder application equipment for wire production. Background Technology

[0002] Electrical wires generally consist of wire cores and an insulation layer. Each wire core includes a copper core and an outer sheath. During wire production, several wire cores are twisted together, and then an insulation layer is applied to the surface of each wire core using an extruder. To prevent the wire cores from sticking to the insulation layer, a thin layer of talcum powder is applied to the surface of the wire cores using a talcum powder coating device.

[0003] Existing talc powder application devices have a simple structure but suffer from uneven powder application. Therefore, improvements are being made to the talc powder application devices used in wire production. Utility Model Content

[0004] In view of the shortcomings of the prior art, this application provides a talc powder application device for wire production, which overcomes the shortcomings of the prior art and aims to solve the problem that some talc powder application devices have simple structure and uneven powder application.

[0005] To achieve the above objectives, this application provides the following technical solution: a talc powder application device for wire production, comprising an application box, wherein an inlet and an outlet are respectively provided on both sides of the application box, a limiting unit is fixedly installed on one side of the inlet, two partitions are fixedly installed inside the application box, and the application box divides its internal space into an application trough and two collection troughs through the two partitions, a rotating rod is provided inside the application trough, and a spiral blade is fixedly connected to the outer surface of the rotating rod inside the application trough, and a drive unit for driving the rotating rod to rotate is fixedly installed on one side of the application box.

[0006] By adopting the above technical solution and setting a limiting unit at the inlet, the wire can be prevented from swinging randomly, ensuring that the wire can stably extend into the powder box from the inlet and extend out through the outlet. The drive unit drives the rotating rod to rotate so that the spiral blades can rotate synchronously. Through the rotation and conveying of the spiral blades, the talc powder inside the powder box can be evenly coated on the surface of the wire, avoiding local accumulation or missed coating.

[0007] As a preferred technical solution of this application, the drive unit includes a drive motor fixedly installed on the upper powder box support leg, a main rotating wheel fixedly installed at the output end of the drive motor, a driven wheel arranged above the main rotating wheel, and the driven wheel fixedly connected to one end of the rotating rod, and a belt arranged between the main rotating wheel and the driven wheel.

[0008] By adopting the above technical solution, the rotating rod can rotate under the drive of the drive motor through the transmission cooperation between the main rotating wheel, the driven rotating wheel and the belt.

[0009] As a preferred technical solution of this application, two bearing seats are symmetrically arranged on the outer surface of the rotating rod on both sides of the spiral blade. The bearing seats are fixedly installed inside the partition, and the rotating rod passes through the partition through the bearing seats and is movably connected to the partition.

[0010] By adopting the above technical solution, it is ensured that the rotating rod can rotate flexibly. At the same time, the connection between the bearing seat and the partition plate ensures that the rotating rod can remain stable during rotation, reducing friction and wear.

[0011] As a preferred technical solution of this application, a protective cover is fixedly installed on one side of the outer wall of the powder box, and the main rotating wheel, the driven rotating wheel and the belt are all located inside the protective cover.

[0012] By adopting the above technical solution, protective covers are installed to protect the main rotating wheel, the driven rotating wheel, and the belt, preventing grinding powder from adhering to the outer surfaces of the main rotating wheel, the driven rotating wheel, and the belt.

[0013] As a preferred technical solution of this application, the limiting unit includes a mounting frame fixedly installed on the outer wall of one side of the powder box. Two vertical guide rollers are rotatably mounted on the upper surface of the mounting frame. A connecting plate is fixedly mounted on the upper surface of the mounting frame on one side of the vertical guide rollers. Two transverse guide rollers are rotatably mounted on the outer surface of the connecting plate.

[0014] By adopting the above technical solution, the wire is limited and guided by the cooperation between the vertical guide roller and the horizontal guide roller, preventing the wire from swinging randomly and ensuring that the wire can move stably.

[0015] As a preferred technical solution of this application, both partitions have notches at their tops, and the bottom of the notches is higher than the top of the spiral blades.

[0016] By adopting the above technical solution, it is ensured that the wires will not come into contact with the spiral blades when the powder box moves, thus preventing the spiral blades from causing unnecessary damage to the wires.

[0017] As a preferred technical solution of this application, the two collection troughs are symmetrically distributed on both sides of the powder trough, and the inner bottom wall of the two collection troughs is provided with through holes. The bottom of the powder box is fixedly installed below the through holes, and a collection box is provided below the outlet of the collection pipe.

[0018] By adopting the above technical solution, the talc powder in the powder loading tank can easily overflow and fall out of the tank under the rotation of the spiral blades. The collection tank can collect the overflowing talc powder and transport it to the collection box through the cooperation between the through hole and the collection pipe, which is convenient for later reuse.

[0019] As a preferred technical solution of this application, an extension section is fixedly connected to one side of the outlet, and the extension section is inclined, and a sealing cover is rotatably installed on one side of the upper surface of the powder box.

[0020] By adopting the above technical solution, after the wire passes through the powder loading trough, due to vibration and other reasons, excess talcum powder on the wire will fall onto the extension section, which will collect it. The sealing cover helps to ensure the airtightness of the powder loading box and prevent powder leakage. At the same time, it also facilitates the addition or cleaning of powder.

[0021] The beneficial effects of this application are:

[0022] In this invention, by setting a limiting unit at the inlet, the wire can be prevented from swinging randomly, ensuring that the wire can stably extend into the powder box from the inlet and extend out through the outlet. The drive unit drives the rotating rod to rotate so that the spiral blades can rotate synchronously. Through the rotation and conveying of the spiral blades, the talc powder inside the powder box can be evenly coated on the surface of the wire, avoiding local accumulation or missed coating.

[0023] With reference to the following description and accompanying drawings, specific embodiments of the present invention are disclosed in detail, indicating the ways in which the principles of the present invention can be adopted. It should be understood that the scope of the embodiments of the present invention is not limited thereto. Attached Figure Description

A drive unit 8, which drives the rotating rod 6 to rotate, is fixedly installed on the side. During use, a limiting unit 9 is set at the inlet 101 to prevent the wire from swinging randomly, ensuring that the wire can stably extend into the powder box 1 from the inlet 101 and extend out through the outlet 102. The drive unit 8 drives the rotating rod 6 to rotate so as to drive the spiral blade 7 to rotate synchronously. Through the rotation and conveying of the spiral blade 7, the talc powder inside the powder tank 4 can be evenly coated on the surface of the wire, avoiding local accumulation or missed coating.

[0031] In this embodiment, as Figure 3As shown, the drive unit 8 includes a drive motor 801 fixedly mounted on the support leg of the upper powder box 1. A main rotating wheel 802 is fixedly mounted on the output end of the drive motor 801.

A belt 804 is arranged between the main rotating wheel 802 and the driven wheel 803. In use, the rotating rod 6 can rotate under the drive of the drive motor 801 through the transmission cooperation between the main rotating wheel 802, the driven wheel 803 and the belt 804.

[0032] In this embodiment, as Figure 3 As shown, two bearing seats 12 are symmetrically arranged on the outer surface of the rotating rod 6 on both sides of the spiral blade 7. The bearing seats 12 are fixedly installed inside the partition plate 3. The rotating rod 6 passes through the partition plate 3 through the bearing seats 12 and is movably connected to the partition plate 3. In use, this ensures that the rotating rod 6 can rotate flexibly. At the same time, the connection between the bearing seats 12 and the partition plate 3 ensures that the rotating rod 6 can remain stable during rotation, reducing friction and wear.

[0033] In this embodiment, as Figure 1 and 3 As shown, a protective cover 10 is fixedly installed on one side of the outer wall of the powder box 1. The main rotating wheel 802, the driven rotating wheel 803 and the belt 804 are all located inside the protective cover 10. In use, the protective cover 10 protects the main rotating wheel 802, the driven rotating wheel 803 and the belt 804, preventing the outer surfaces of the main rotating wheel 802, the driven rotating wheel 803 and the belt 804 from being contaminated with grinding powder.

[0034] In this embodiment, as Figure 4 As shown, the limiting unit 9 includes a mounting bracket 901 fixedly installed on the outer wall of one side of the powder box 1. Two vertical guide rollers 902 are rotatably mounted on the upper surface of the mounting bracket 901. A connecting plate 903 is fixedly mounted on the upper surface of the mounting bracket 901 on one side of the vertical guide rollers 902. Two horizontal guide rollers 904 are rotatably mounted on the outer surface of the connecting plate 903. In use, the wire is limited and guided by the cooperation between the vertical guide rollers 902 and the horizontal guide rollers 904 to prevent the wire from swinging randomly and ensure that the wire can move stably.

[0035] In this embodiment, as Figure 2 As shown, both partitions 3 have openings 13 at their tops, and the bottom of the openings 13 is higher than the top of the spiral blades 7. During use, this ensures that the wires do not come into contact with the spiral blades 7 when the powder box 1 moves, thus preventing the spiral blades 7 from causing unnecessary damage to the wires.

[0036] In this embodiment, as Figure 2As shown, two collecting troughs 5 are symmetrically distributed on both sides of the upper powder trough 4, and the inner bottom wall of both collecting troughs 5 is provided with through holes 14. The bottom of the upper powder box 1 is fixedly installed below the through holes 14. A collection box 16 is provided below the outlet of the collecting pipe 15. When in use, the talc powder in the upper powder trough 4 is easily overflowed and dropped from the upper powder trough 4 under the rotation of the spiral blades 7. The collecting troughs 5 can collect these overflowing and dropped talc powders, and transport the talc powder to the collection box 16 through the cooperation between the through holes 14 and the collecting pipe 15, so as to facilitate the reuse in the later stage.

[0037] In this embodiment, as Figure 1 As shown, an extension section 11 is fixedly connected to one side of the outlet 102, and the extension section 11 is inclined. A sealing cover 2 is rotatably installed on one side of the upper surface of the powder box 1. During use, after the wire passes through the powder trough 4, due to vibration and other reasons, excess talcum powder on the wire will fall onto the extension section 11 and be collected by the extension section 11. The sealing cover 2 helps to ensure the airtightness of the powder box 1 and prevent powder leakage. At the same time, it also facilitates the addition or cleaning of powder.

[0038] Working principle: By setting a limiting unit 9 at the inlet 101, the wire can be prevented from swinging randomly, ensuring that the wire can stably extend into the powder box 1 from the inlet 101 and extend out through the outlet 102. The drive unit 8 drives the rotating rod 6 to rotate so as to drive the spiral blade 7 to rotate synchronously. Through the rotation and conveying of the spiral blade 7, the talc powder inside the powder tank 4 can be evenly coated on the surface of the wire, avoiding local accumulation or missed coating.
