Description

Technical Field

[0001] This utility model relates to the technical field of enameled wire production equipment, and in particular to a wire cooling and traction device for enameled wire coating. Background Technology

[0002] Enamelled wire typically has a dozen or more coating layers. During production, each coating layer requires baking and curing before the next layer can be applied, necessitating cooling after baking. In existing technology, each coating machine is equipped with a wire cooling device, such as the cooling device disclosed in CN116313291A for enamelled wire production. This device features multiple hollow guide wheels connected in series on the bottom inner wall of the cooling box. The enamelled wire passes through these guide wheels, with cooling water flowing between them to achieve cooling. However, in enamelled wire production plants, multiple coating machines are typically equipped with separate wire cooling devices. Each device requires maintenance and repair, and the limited installation space next to the coating machines results in small heat exchangers, limiting their cooling effect on the heated coolant and leading to poor overall cooling of the enamelled wire.

Detailed Implementation

[0030] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0031] The following is combined with Figures 1 to 6This invention describes a wire cooling and traction device for enameled wire coating according to an embodiment of the present invention.

[0032] In this embodiment, multiple wire cooling traction devices 02 are respectively connected to a centralized cooling system 01 within the factory. The cooling water for the wire cooling traction devices 02 originates from the centralized cooling system 01. Compared to the small cooling devices for the enameled wires 03 on each coating machine, the centralized cooling system 01 has better heat exchange efficiency and can effectively reduce the cooling water temperature. For example, the centralized cooling system 01 is a cooling tower, specifically a spray cooling tower. The centralized cooling system 01 can not only provide cooling water for the enameled wires 03 but also provide cold cooling water for other equipment with cooling requirements, greatly simplifying the configuration of cooling equipment and reducing maintenance difficulty.

[0033] The wire cooling traction device 02 includes a cooling traction roller shaft 1 and multiple guide wheels, the multiple guide wheels being used to guide the enameled wire 03 around the cooling traction roller shaft 1;

[0034] The cooling traction roller shaft 1 is provided with a coolant chamber. One end of the cooling traction roller shaft 1 is provided with a rotary joint 3. The coolant chamber is connected to the rotary joint 3. The rotary joint 3 is connected to a cooling water inlet pipe 33 and a water outlet pipe 34. The cooling water inlet pipe 33 and the water outlet pipe 34 are respectively connected to the centralized cooling equipment 01 in the plant.

[0035] In this invention, multiple enameled wires 03 are simultaneously cooled by the cooling traction roller shaft 1, in conjunction with a sufficiently low-temperature cooling water supply, which greatly improves the cooling efficiency of the enameled wires 03. It is understood that the cooling traction roller shaft 1 is connected to a drive motor.

[0036] In order to achieve the circulation of cooling water in the cooling traction roller 1, in one embodiment of the present invention, the cooling liquid chamber is respectively inlet chamber 11 and return chamber 12. The inlet chamber 11 is arranged around the return chamber 12. The first end of the inlet chamber 11 is connected to the first end of the return chamber 12. The second end of the inlet chamber 11 is connected to the cooling water inlet pipe 33 through the rotary joint 3. The second end of the return chamber 12 is connected to the outlet pipe 34 through the rotary joint 3.

[0037] The outer wall of the liquid inlet chamber 11 is the outer wall of the cooling traction roller shaft 1.

[0038] By equipping the cooling traction roller shaft 1 with an inlet chamber 11 and a return chamber 12, cooling water enters the inlet chamber 11 through the rotary joint 3 and exchanges heat with the enameled wire 03. Then, it flows from the end of the inlet chamber 11 to the return chamber 12 and is discharged through the rotary joint 3 to the outlet pipe 34, thus limiting the flow direction of the cooling water and achieving a reliable cooling effect on the enameled wire 03.

[0039] Specifically, the cooling traction roller 1 includes a hollow roller 13 and a return pipe 14 located in the hollow roller 13, and the hollow roller 13 and the return pipe 14 are coaxially arranged.

[0040] The cavity between the hollow roller 13 and the return pipe 14 is the liquid inlet cavity 11, and the inner cavity of the return pipe 14 is the return cavity 12.

[0041] One end of the return pipe 14 is positioned at one end of the hollow roller 13 by the sealing plate 15. The other end of the hollow roller 13 is provided with a connecting component 2. The liquid inlet chamber 11 and the return chamber 12 are connected to the rotary joint 3 through the connecting component 2. The sealing plate 15 and the connecting component 2 are rotatably mounted on the frame 4.

[0042] The inlet chamber 11 and return chamber 12 of the cooling traction roller shaft 1 are formed by a hollow roller 13 and a return pipe 14. The sealing plate 15 and connecting assembly 2 are used to close the inlet chamber 11 and return chamber 12 and connect them to the rotary joint 3, simplifying the structure of the cooling traction roller shaft 1. For example, the end of the return pipe 14 away from the rotary joint 3 has multiple through holes for connecting the inlet chamber 11 and return chamber 12. In other embodiments, the end of the return pipe 14 is connected to the sealing plate 15 via a metal mesh to connect the inlet chamber 11 and return chamber 12. The return pipe 14 and the sealing plate 15 can be connected by a sleeve or a snap-fit ​​connection.

[0043] To achieve communication between the cooling traction roller shaft 1 and the rotary joint 3, the connecting assembly 2 further includes a connecting plate 21 and a connecting shaft 24 connected to each other. The connecting plate 21 is provided with an annular hole 22 and a central hole 23. The annular hole 22 is connected to the liquid inlet chamber 11, and the central hole 23 is connected to the return chamber 12. The middle hole of the connecting shaft 24 is connected to the central hole 23 and the water outlet of the rotary joint 3, respectively. The eccentric holes of the connecting shaft 24 are distributed to connect the annular hole 22 and the water inlet of the rotary joint 3. The connecting shaft 24 is mounted on the frame 4 via bearings.

[0044] The connecting assembly 2 consists of a connecting plate 21 and a connecting shaft 24, which not only enables the connection between the cooling traction roller shaft 1 and the rotary joint 3, but also allows the cooling traction roller shaft 1 to be rotatably mounted on the frame 4 via the connecting shaft 24. For example, the connecting plate 21 and the connecting shaft 24 are connected by welding.

[0045] Furthermore, the rotary joint 3 includes a rotating tube 31 and a fixed tube 32, with a bearing disposed between the rotating tube 31 and the fixed tube 32; the end of the rotating tube 31 is fixedly connected to the end of the connecting shaft 24, and the fixed tube 32 is connected to the cooling water inlet pipe 33 and the water outlet pipe 34. For example, the end of the rotating tube 31 is connected to the end of the connecting shaft 24 via a flange. The rotating tube 31 has a central through hole and an outer through hole; the outer through hole communicates with the cooling water inlet pipe 33 through the fixed tube 32, and the central through hole communicates with the water outlet pipe 34 through the fixed tube 32; the central through hole communicates with the central hole of the connecting shaft 24, and the outer through hole communicates with the eccentric hole of the connecting shaft 24. The number of outer through holes and eccentric holes can be multiple.

[0046] In one embodiment of this utility model, the plurality of guide rollers are divided into an upper guide roller group 5, a lower guide roller group 6, and an inlet guide roller group 7. The upper guide roller group 5 and the lower guide roller group 6 are respectively located on the upper and lower sides in front of the cooling traction roller shaft 1, and the inlet guide roller group 7 is located at the rear and lower part of the cooling traction roller shaft 1. The enameled wire 03 passes through the upper guide roller group 5, the lower guide roller group 6, and the inlet guide roller group 7 in sequence before passing through the cooling traction roller shaft 1.

[0047] The arrangement of multiple guide wheel sets allows for a large contact length between the enameled wire 03 and the cooling traction roller shaft 1, resulting in a good cooling effect.

[0048] Preferably, the cooling traction roller shaft 1 has multiple separating mechanisms 8; the separating mechanism 8 includes a separating line 81, a guide wheel 82 and a separating wheel 83, the guide wheel 82 is used to guide the separating line 81 to pass around the cooling traction roller shaft 1, a separating wheel 83 is provided between two separating lines 81, and the separating wheel 83 is in contact with the roller surface of the cooling traction roller shaft 1; multiple enameled wires 03 are provided between the two sets of separating mechanisms 8.

[0049] Understandably, slight vibrations of the guide wheel or roller and minor shrinkage deformation during cooling may cause the enameled wire 03 to shift position during operation. To prevent the positional shift of the enameled wire 03 from interfering with the operation of adjacent enameled wires 03, a separating mechanism 8 is provided in the cooling traction roller 1 in this invention. More preferably, the surface of the separating wheel 83 is rubber-coated, and the separating line 81 is a flat line with a width greater than that of the enameled wire 03.
