Description

Technical Field

[0001] This utility model relates to a paint recovery device, and more particularly to a paint recovery device for enameled wire. Background Technology

[0002] Enameled wire is a major type of winding wire, consisting of a conductor and an insulation layer. The bare wire is annealed and softened, then undergoes multiple coatings and baking processes. However, producing products that meet both standard requirements and customer specifications is not easy. It is affected by factors such as raw material quality, process parameters, production equipment, and environment. Therefore, the quality characteristics of various enameled wires differ, but they all possess four major properties: mechanical, chemical, electrical, and thermal properties. Currently, enameled wire is typically coated with enamel using spray painting equipment. During the coating process, some enamel is lost, and excessive enamel can easily lead to enamel nodules on the surface, affecting the quality of the enameled wire. Utility Model Content

[0003] The purpose of this invention is to provide a device for recovering enamel from enameled wire. It enables effective recovery of the enamel and avoids the impact on recovery efficiency caused by fibers falling off during the enamel scraping process using felt.

[0004] The technical solution of this utility model is as follows: A device for recovering enameled wire varnish includes a workbench, a paint spraying box on the upper side of the workbench, a paint spraying chamber inside the paint spraying box, an inlet hole and an outlet hole on the front and rear sides of the paint spraying chamber, a conical collection hopper at the bottom of the paint spraying chamber, a felt scraper on the upper side of the conical collection hopper, a filter plate assembly on the conical collection hopper, a cleaning component on the filter plate assembly, and a paint tank located below the workbench at the bottom of the conical collection hopper connected to the paint tank located below the workbench via a conduit. In the aforementioned enameled wire varnish recovery device, the filter plate assembly includes an annular upper platform, an upwardly positioned baffle on the outer edge of the upper platform, a downwardly positioned guide plate on the inner edge of the upper platform, a filter plate with a circular cross-section at the lower end of the guide plate, and a fixedly positioned toothed ring at the lower part of the upper platform.

[0005] In the aforementioned enameled wire varnish recovery device, the conical collection hopper includes a conical part, and a horizontally arranged mounting plate is provided on the upper end of the conical part. The mounting plate is provided with a drive gear corresponding to the gear ring, and multiple sets of evenly distributed support columns are provided on the mounting plate. The upper end of the support columns is provided with ball bearings.

[0006] In the aforementioned enameled wire varnish recovery device, the cleaning component includes a mounting column connected to the top of the spraying chamber, and horizontally arranged cleaning brushes on both sides of the lower end of the mounting column.

[0007] Compared with the prior art, the present invention has the following advantages: This application uses a conical collection hopper for paint recovery during the painting process. Since the felt fibers can easily enter the recovered paint when scraping off excess paint from the surface of the enameled wire, this application uses a rotating filter plate assembly to clean the filter plate surface, preventing the filter plate surface from being clogged by the falling felt fibers, resulting in good recovery effect.

Detailed Implementation

[0010] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.

[0011] Example. A device for recovering enamel from enameled wire, configured as follows: Figure 1-2 As shown, the system includes a workbench 1, a paint spray box 2 on the upper side of the workbench 1, a paint spray chamber 3 inside the paint spray box 2, an inlet hole 4 and an outlet hole 5 on the front and rear sides of the paint spray chamber 3 respectively, a conical collection hopper 6 at the bottom of the paint spray chamber 3, a felt scraper 7 on the upper side of the conical collection hopper 6, a filter plate assembly 8 on the conical collection hopper 6, a cleaning component 11 on the filter plate assembly 8, and a paint tank 10 located on the lower side of the workbench 1 connected to the lower part of the conical collection hopper 6 via a conduit 9.

[0012] The filter plate assembly 8 includes an annular upper platform 8.1, an upwardly positioned retaining edge 8.2 on the outer edge of the upper platform 8.1, a downwardly positioned guide plate 8.3 on the inner edge of the upper platform 8.1, a filter plate 8.4 with a circular cross-section at the lower end of the guide plate 8.3, and a fixedly positioned toothed ring 8.5 at the lower part of the upper platform 8.1.

[0013] The conical collection hopper 6 includes a conical part 6.1. A horizontally arranged mounting plate 6.2 is provided on the upper end of the conical part 6.1. A drive gear 6.3 corresponding to the gear ring 8.5 is provided on the mounting plate 6.2. A plurality of evenly distributed support columns 6.4 are provided on the mounting plate 6.2. A ball bearing 6.5 is provided on the upper end of the support column 6.4.

[0014] The cleaning component 11 includes a mounting post 12 connected to the top of the paint spraying chamber 3, and horizontally arranged cleaning brushes 13 on both sides of the lower end of the mounting post 12.

[0015] The principle of this utility model is as follows: the enameled wire enters the spraying chamber 3 through the inlet hole 4, is sprayed with paint in the spraying chamber 3, and is sent out through the outlet hole 5. After being sent out, it will be further dried and then wound up by the final winding mechanism. During the painting process, the enameled wire is coated with paint by setting up a paint spray head. The paint spray head can be set on the upper and lower sides of the enameled wire and located in the middle of the spraying chamber. The paint is drawn into the paint spray head by a pump. The enameled wire is further scraped by a felt scraper 7 to remove surface paint. The felt scraper 7 includes a horizontally arranged mounting beam, with both ends connected to the inner walls of the spray booth 2. The mounting beam has multiple sets of mounting holes corresponding to the number of enameled wires, and felt is placed inside the mounting holes. This application is used for enameled wires with relatively low processing precision. The scraped paint is collected through a conical collecting hopper, and the paint splashed during the spraying process is also collected through a conical collecting hopper 6. The collected paint contains impurities such as fibers from the felt scraper 7, so it needs to be filtered through a filter plate. However, due to the high viscosity of the paint, the filter plate surface is easily clogged. This application uses a motor... The drive gear 6.3 rotates, engaging with the gear ring 8.5 to drive the filter plate assembly 8 to rotate. The upper end of the support column 6.4 has ball bearings 6.5 that support the upper platform 8.1. Further, a guide groove corresponding to the ball bearings can be provided on the lower part of the upper platform 8.1. The bottom inner side of the paint spray box 2 has a mounting bracket corresponding to the filter plate assembly 8. The baffle 8.2 of the filter plate assembly can engage with the mounting groove of the paint spray chamber 3, and the paint flows to the filter plate 8.4 via the guide plate 8.3. During the rotation of the filter plate assembly 8, the filter plate 8.4 rotates relative to the cleaning brush 13, which cleans the surface of the filter plate 8.4. This prevents impurities from accumulating on the filter plate surface and causing blockage. When there are many impurities on the cleaning brush, replacing the cleaning brush can improve the cleaning effect.
