Description

Technical Field

[0001] This utility model relates to the field of cable spraying technology, and specifically to a spraying device for spraying cable surface. Background Technology

[0002] After cables are manufactured and put into use, the insulation sheath covering the wire core will age rapidly due to long-term exposure to complex environments such as ultraviolet radiation and acid and alkali corrosion. In order to effectively extend the service life of cables, it is necessary to perform surface protective spraying on cables in use regularly, which requires the use of spraying equipment.

[0003] Current technology typically involves manually spraying cables with a handheld spray gun. This method has several drawbacks: limited by the operator's field of vision and arm range of motion, a single spray can only cover a portion of the cable's surface. To achieve uniform 360-degree coverage, the operator must frequently adjust the spray gun's angle and position, resulting in low efficiency. Furthermore, handheld shaking and unstable grip can cause fluctuations in the spray pattern, increasing paint waste and potentially introducing safety hazards. Utility Model Content

[0028] 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.

[0029] As mentioned earlier, existing technologies typically involve manually spraying cables with a handheld spray gun. This method has several drawbacks: limited by the operator's field of vision and arm range of motion, a single spray can only cover a portion of the cable's surface. To achieve uniform 360-degree coverage, the operator must frequently adjust the spray gun's angle and position, resulting in low efficiency. Furthermore, handheld shaking and unstable grip can cause fluctuations in the spray trajectory, increasing paint waste and potentially introducing safety hazards.

[0030] In view of this, the present invention provides a spraying device for spraying coating on the surface of cables, which solves the above problems. The present invention solves the problem in the following way.

[0031] Example 1:

[0032] Please refer to the instruction manual appendix. Figure 1-4 As shown in the figure, this embodiment provides a spraying device for coating cable surfaces. The spraying device includes at least a spray gun 1, a roller 2, and a spraying section 3. The spray gun 1 is connected to an air source and a paint source, and a high-speed spray of paint is output from the paint source to the nozzle of the spray gun 1 via a switch. The spraying section 3 is located at the nozzle of the spray gun 1 and includes an arc-shaped component 31 with a notch 311, and a first nozzle 32 and a second nozzle 33 fixed to the arc-shaped component 31. Five first nozzles 32 are provided, evenly distributed and fixedly connected to the side of the arc-shaped component 31 near the cable (e.g., ...). Figure 2 On the inner side shown, two second nozzles 33 are provided, and the second nozzles 33 are also fixedly connected to the side of the arc-shaped member 31 near the cable (as shown). Figure 2 On the inner side shown, the second nozzle 33 is positioned near the notch 311.

[0033] In this first embodiment, the arc-shaped component 31 has a channel inside that accommodates the paint. This channel is connected to the nozzle of the spray gun 1, the first nozzle 32, and the second nozzle 33. The first nozzle 32 and the second nozzle 33 are respectively provided with a first spray chamber 321 and a second spray chamber 331 (e.g., Figure 3 and Figure 4 As shown), the first spray chamber 321 is symmetrically opened inside the first nozzle 32. The paint is sprayed out from the first spray chamber 321 to form a fan-shaped, symmetrical first spray area 322. Since the nozzle of the first nozzle 32 is facing the surface of the cable (i.e., the extension line of the symmetrical center of the first spray chamber 321 passes through the center of the cable), the paint sprayed from the first nozzle 32 into the first spray area 322 can be evenly divided into two symmetrical parts on the surface of the cable.

[0034] Meanwhile, the second spray chamber 331 is asymmetrically opened within the second nozzle 33 (e.g. Figure 4As shown), the asymmetrical second spray chamber 331 has a steep slope 3311 and a gentle slope 3312, with the steep slope 3311 located on the side closer to the first nozzle 32 (i.e., the gentle slope 3312 located on the side closer to the notch 311). Therefore, the paint is sprayed out from the second spray chamber 331, which is an asymmetrical second spray chamber 331. The second spray domain 332 it sprays is also an asymmetrical second spray domain 332. The second spray domain 332 is divided into two parts, namely the part where the gentle slope 3312 is located and the part where the steep slope 3311 is located. The part where the steep slope 3311 is located has the same area as the symmetrical part of the first spray domain 322 (that is, the area covered by the steep slope 3311 is half of the area of ​​the first spray domain 322), while the area of ​​the part where the gentle slope 3312 is located is larger than the area of ​​the part where the steep slope 3311 is located. This allows the extension line of the surface where the gentle slope 3312 is located to extend to the bottom of the cable (the bottom is the part of the cable corresponding notch 311) and cover the surface of the cable in that part.

[0035] Ultimately, as Figure 2 As shown, all the first spray areas 322 and all the second spray areas 332 are grouped together to form a circular spraying area. The cable surface within this area can be coated with paint without any blind spots. This allows the operator to spray the cable surface with the equipment designed in this embodiment without frequently changing the equipment position, thus improving the efficiency of spraying and the coverage effect.

[0036] The size of the notch 311 (i.e., the distance between the two adjacent end faces of the notch 311) is larger than the diameter of the cable, such as... Figure 2 As shown, the distance β (i.e., the size of the notch 311) is greater than the distance α (i.e., the diameter of the cable). Therefore, in the specific implementation of this embodiment, the operator passes the arc-shaped component 31 through the cable at the notch 311 to the predetermined position and then opens the spray gun 1 to spray. The paint passes through the spray gun 1, the arc-shaped component 31, the first nozzle 32, and the second nozzle 33, and is finally sprayed onto the outer surface of the cable, thus achieving coating. At this time, moving the position of the spray gun 1 allows for all-around spraying of the outer surface of the cable according to its length. After the coating is completed, the spray gun 1 and the arc-shaped component 31 are retracted from the notch 311, completing the operation.

[0037] Example 2:

[0038] Based on the above embodiments, in order to further clarify and completely explain the technical solutions therein, this utility model also provides an embodiment two. For example... Figures 5 to 6 As shown, in this second embodiment, four rollers 2 are provided on both sides of the spray gun 1 (two rollers on one side are configured to cooperate with each other), and the rollers 2 have an arc surface 21 (such as...). Figure 6As shown, the curved surface 21 is attached to the surface of the cable. Therefore, during use, the operator places the roller 2 against the surface of the cable, then moves the spray gun 1, and the roller 2 moves accordingly to perform the aforementioned spraying. As the roller 2 rolls along the surface of the cable, the distance between the spray gun 1 and the curved part 31 and the surface of the cable remains constant, which increases the stability of the spraying process and further improves the efficiency of the spraying.

[0039] Example 3:

[0040] Based on the above embodiments, in order to further clarify and completely explain the technical solutions therein, this utility model also provides Embodiment Three. For example... Figure 5 As shown, in this third embodiment, the roller 2 is connected to the side of the spray gun 1 via an adjustment mechanism 4. The adjustment mechanism 4 includes a fixing plate 41 fixed to the spray gun 1, and an adjustment plate 42 with several adjustment holes 421 is rotatably connected to the fixing plate 41, and is fastened or adjusted by screws and nuts. A support plate 43 is rotatably connected to one of the adjustment holes 421, and is fastened or adjusted by screws and nuts.

[0041] A fixed shaft 44 is inserted into the end of the support plate 43 away from the adjusting plate 42. The fixed shaft 44 is also fastened by screws and nuts. Both ends of the fixed shaft 44 have rotating balls 441. A ball seat is rotatably connected to the side of the roller 2 near the rotating ball 441. A cover is provided on the ball seat. The cover is screwed onto the ball seat to form a space for accommodating the rotating ball 441. By screwing the cover, the tightness and rotation degree between the ball seat and the rotating ball 441 can be adjusted, thereby adjusting the orientation of the roller 2 to better adapt to the surface of the cable.

[0042] Therefore, in summary, the spraying device for coating cable surfaces and its various embodiments of this utility model have the following advantages, including but not limited to, compared with the prior art:

[0043] The spray gun 1 of this utility model is provided with an arc-shaped component 31, on which a plurality of first nozzles 32 and second nozzles 33 are fixed. The paint is sprayed out from the first nozzles 32 and second nozzles 33 through the spray gun 1, forming a first spray area 322 and a second spray area 332 respectively. The first spray area 322 and the second spray area 332 together form a circular spraying area, which can effectively cover the outer surface of the cable duct, so that the operator can achieve full spraying without frequently changing the position of the spray gun.

[0044] Furthermore, the present invention also provides rollers 2 on both sides of the spray gun 1. The rollers 2 roll in contact with the surface of the cable, so that when the operator operates the spray gun 1 to spray, the first nozzle 32 and the second nozzle 33 can always maintain a fixed distance from the cable, which makes the spraying more stable.

[0045] Finally, the positions of roller 2 and spray gun 1 can also be adjusted by adjusting the gap between the roller 42 and the adjusting hole 421 thereon, so that the gap between the spray gun 1 and the arc-shaped part 31 and the cable surface can be adjusted in a timely manner according to actual use.

[0046] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of this utility model and its equivalents, this utility model also intends to include these modifications and variations.
