Description

Technical Field

[0001] This utility model relates to the field of coil coating technology, specifically to an electromagnetic wire coating device with adjustable adhesive film thickness. Background Technology

[0002] Applying adhesive is the core step in the entire cable coating process. Commonly used coating methods include cold-press coating, hot-melt coating, and curing coating. However, existing coating methods involve applying cured adhesive to the cable surface through a coating head, which makes it difficult to control the coating thickness. Furthermore, excessive adhesive can drip onto the work surface, soiling the work environment. Additionally, manual replenishment of adhesive is required during the coating process. Therefore, a coating device for electromagnetic wires was designed. This device uses an outer and inner adhesive box to collect excess adhesive from the electromagnetic wires, preventing drips onto the work surface. A pump is also used to circulate the adhesive, maintaining the adhesive level in the boxes, reducing worker workload, and ensuring uniform adhesive distribution on the electromagnetic wires. Utility Model Content

[0003] The purpose of this invention is to provide an electromagnetic wire coating device with adjustable adhesive film thickness. An inner adhesive box is located at the center of the outer adhesive box. An electromagnetic wire passes through the inner adhesive box, allowing adhesive to be applied to the wire, thus completing the coating process. The overflow of adhesive from the inner adhesive box ensures a consistent adhesive level. Simultaneously, a pump returns adhesive from the outer box to the inner box, further ensuring the correct adhesive level. This reduces the need for refilling adhesive, lowers labor intensity, and ensures the electromagnetic wire is completely submerged in adhesive, guaranteeing uniform adhesive distribution on the wire surface.

[0004] This utility model provides the following technical solution: an electromagnetic wire coating device with adjustable film thickness, including a mounting base plate, a glue box assembly fixed in the middle of the mounting base plate, a front guide assembly and a rear guide assembly fixed on both sides of the glue box assembly on the mounting base plate respectively, and a coating mold provided between the glue box assembly and the rear guide assembly. The coating mold is fixed on the mounting base plate by a mold bracket. The coating mold is used to control the thickness of the applied glue. The electromagnetic wire passes through the front guide assembly, the glue box assembly, the mold and the rear guide assembly in sequence to complete the coating of the electromagnetic wire.

[0005] The glue box assembly includes an outer glue box and an inner glue box. The inner glue box is fixed at the center of the outer glue box, and a gap is formed between the inner glue box and the outer glue box. The inner glue box is used to fill glue. The outer glue box is connected to a pump for delivering the glue from the outer glue box to the inner glue box.

[0006] Furthermore, a first semi-circular hole is provided on the opposite end faces of the outer glue box, and a second semi-circular hole is provided on the opposite end faces of the inner glue box. Both the first and second semi-circular holes are used to pass electromagnetic wires. The bottom surface of the second semi-circular hole is lower than the bottom surface of the first semi-circular hole. The glue in the inner glue box will flow from the second semi-circular hole into the outer glue box. The glue in the outer glue box will be pumped back into the inner glue box by a pump to realize the return flow of glue and ensure the liquid level of glue.

[0007] Furthermore, the front-end guide assembly includes a front-end vertical bracket, the lower end of which is rotatably connected to two left and right distributed front-end vertical guide rollers to limit and guide the left and right positions of the electromagnetic wire.

[0008] Furthermore, the front-end guide assembly also includes a front-end horizontal bracket, on the side of which are rotatably connected front-end horizontal guide rollers distributed vertically to limit and guide the vertical position of the electromagnetic wire.

[0009] Furthermore, the rear-end guide assembly includes a rear-end horizontal support, on which two rear-end horizontal guide rollers distributed vertically are rotatably connected to roll the adhesive layers on the upper and lower sides of the electromagnetic wire.

[0010] Furthermore, the rear-end guide assembly also includes a rear-end vertical bracket, on which two rear-end vertical guide rollers are rotatably connected to be distributed on the left and right sides to roll the adhesive layer on the left and right sides of the electromagnetic wire.

[0011] Furthermore, the front horizontal bracket and the rear horizontal bracket are respectively set on both sides of the outer glue box to keep the electromagnetic wire horizontal, thereby ensuring uniform glue distribution and avoiding quality problems.

[0012] Furthermore, the front vertical bracket, the front horizontal bracket, the rear horizontal bracket, and the rear vertical bracket are all provided with waist holes on their surfaces. The waist holes are used to move the position of the front vertical guide roller, the front horizontal guide roller, the rear horizontal guide roller, or the rear vertical guide roller, adjust the gap between the guide rollers, and roll the adhesive layer on the electromagnetic wire through the guide rollers to improve the adhesive coating quality.

[0013] Furthermore, both the front horizontal guide roller and the rear horizontal guide roller include screws, washers, roller support shafts, and roller support bearings. The roller support shaft has a clamping plate. Tightening the screws positions the roller support shaft. The roller support bearings are sleeved on the roller support shaft. The screws, washers, and clamping plates are used to position the front or rear horizontal guide rollers and adjust the distance between the guide rollers.

[0014] Furthermore, the adhesive coating mold includes molds with various aperture specifications, used to control the thickness of the adhesive on electromagnetic wires of different sizes.

[0015] Compared with the prior art, the beneficial effects achieved by this utility model are:

[0016] (1) By setting an inner box in the center of the outer box, the electromagnetic wire passes through the inner box and the glue is applied to the electromagnetic wire to complete the glue application. The overflow of glue inside the inner box ensures the glue level. At the same time, the glue in the outer box is returned to the inner box by the pump, which further ensures the glue level, reduces the glue replenishment process, reduces labor intensity, and further ensures that the electromagnetic wire is completely immersed in the glue, ensuring the uniformity of glue distribution on the surface of the electromagnetic wire.

[0017] (2) At the same time, the outer glue box can collect excess glue on the electromagnetic wire, preventing glue from dripping onto the workbench.

[0018] (3) The thickness of the adhesive layer on the surface of the electromagnetic wire is controlled by using an adhesive coating mold;

[0019] (4) Roll the adhesive layers on the upper and lower sides of the electromagnetic wire and the left and right sides of the electromagnetic wire with horizontal guide rollers and vertical guide rollers respectively to further control the thickness of the adhesive layer.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0027] Please see Figures 1 to 4 The present invention provides a technical solution: an electromagnetic wire coating device with adjustable film thickness, comprising a mounting base plate 1, a glue box assembly fixed in the middle of the mounting base plate 1, the glue box assembly being used to fill glue, a front guide assembly and a rear guide assembly respectively fixed on both sides of the glue box assembly on the mounting base plate 1, the front guide assembly and the rear guide assembly being used to guide the electromagnetic wire 16 to keep the electromagnetic wire horizontal, and a coating mold 9 is also provided between the glue box assembly and the rear guide assembly, the coating mold 9 being fixed on the mounting base plate 1 by a mold bracket 8, the coating mold 9 being used to control the thickness of the glue applied, the electromagnetic wire 16 passing through the front guide assembly, the glue box assembly, the mold and the rear guide assembly in sequence to complete the coating of the electromagnetic wire 16;

[0028] The glue box assembly includes an outer glue box 6 and an inner glue box 7. The inner glue box 7 is fixed at the center of the outer glue box 6, forming a gap between them. The inner glue box 7 is used to fill the glue. The outer glue box 6 is connected to a pump to transport the glue from the outer glue box 6 to the inner glue box 7. The pump also allows the glue in the outer glue box 6 to flow back into the inner glue box 7, ensuring the liquid level in the inner glue box 7. This allows the electromagnetic wire 16 to pass through the glue, evenly covering it. The electromagnetic wire 16 passes through the inner glue box 7, where the glue completely wraps around it. Simultaneously, the outer glue box 6 collects any excess glue dripping from the electromagnetic wire 16, preventing it from dripping onto the mounting base plate 1. Compared to existing brush-type glue application methods, this method is more uniform and eliminates the need for manual glue replenishment. It completely covers the electromagnetic wire 16 with glue, improving the quality of the glue application and preventing glue from dripping onto the outside and soiling the working environment.

[0029] The outer glue box 6 has a first semi-circular hole 61 on each of its opposite ends, and the inner glue box 7 has a second semi-circular hole 71 on each of its opposite ends. Both the first semi-circular hole 61 and the second semi-circular hole 71 are used to pass through the electromagnetic wire 16. The bottom surface of the second semi-circular hole 71 is lower than the bottom surface of the first semi-circular hole 61. The glue in the inner glue box 7 overflows from the second semi-circular hole 71 and flows into the outer glue box 7. The glue in the outer glue box 7 is pumped back into the inner glue box 7 to achieve glue circulation and ensure the liquid level. At the same time, excess glue on the electromagnetic wire 16 will also drip into the outer glue box 6.

[0030] The front-end guide assembly includes a front-end vertical bracket 2. The lower end of the front-end vertical bracket 2 is connected to two front-end vertical guide rollers 3 distributed on the left and right. The electromagnetic wire 16 is located between the two front-end vertical guide rollers 3. The two front-end vertical guide rollers 3 guide and limit the left and right sides of the electromagnetic wire 16.

[0031] The front-end guide assembly also includes a front-end horizontal support 4, on the side of which are rotatably connected front-end horizontal guide rollers 5 distributed vertically, which guide and limit the upper and lower sides of the electromagnetic wire 16.

[0032] The rear guide assembly includes a rear horizontal support 10, on which two rear horizontal guide rollers 11 are rotatably connected. When the rear horizontal guide rollers 11 limit the upper and lower sides of the electromagnetic wire 16, they can also press and roll the adhesive layer on the upper and lower surfaces of the electromagnetic wire 16 to ensure the thickness of the adhesive layer.

[0033] The rear guide assembly also includes a rear vertical support 12, on which two rear vertical guide rollers 13 are rotatably connected. The rear vertical guide rollers 13 press and roll the adhesive layer fixed on the left and right sides of the electromagnetic wire 16 to ensure the thickness of the adhesive layer.

[0034] The front horizontal support 4 and the rear horizontal support 10 are respectively set on both sides of the outer glue box 6, so that the electromagnetic wire 16 on the outside of the outer glue box 6 and the electromagnetic wire 16 inside the glue assembly are on the same horizontal plane, so that the electromagnetic wire 16 is kept horizontal and avoids the electromagnetic wire 16 from being completely exposed during the glue coating process, which would affect the uniformity of the glue coating layer.

[0035] like Figure 1 As shown, the front vertical support 2, the front horizontal support 4, the rear horizontal support 10, and the rear vertical support 12 are all provided with waist holes. The waist holes are used to move the position of the front vertical guide roller 3, the front horizontal guide roller 5, the rear horizontal guide roller 11, or the rear vertical guide roller 13, and adjust the gap between the guide rollers, so as to guide the electromagnetic wires 16 of different thicknesses and meet the applicable range of the equipment.

[0036] like Figure 4 As shown, both the front horizontal guide roller 5 and the rear horizontal guide roller 11 include screws 19, pads 17, roller support shafts 14 and roller support bearings 15. A clamping plate 18 is formed on the roller support shaft 14. When the screws 19 are tightened, the pads 17 and clamping plates 18 are distributed on both sides of the front horizontal support 4 or the rear horizontal support 10 to position the roller support shaft 14. The roller support bearings 15 are sleeved on the roller support shaft 14. By tightening the screws 19, the position of the rollers is controlled, and the gap between the rollers is further controlled to meet the usage requirements of electromagnetic wires 16 of different thicknesses.

[0037] The glue-coating mold 9 includes molds with different aperture specifications, which are used to control the thickness of the glue for electromagnetic wires of different specifications and sizes. Different specifications of glue-coating mold 9 are selected for electromagnetic wires of different sizes, and different molds are also selected for different glue thicknesses, so as to ensure the thickness of the glue.

[0038] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
