Description

Technical Field

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

[0002] A cable is a rope-like cable made of several or several groups of conductors twisted together. Each group of conductors is insulated from each other and is often twisted around a central core. The entire cable is covered with a highly insulating outer layer. During the cable production process, special coatings are sprayed onto its outer surface to meet its use under special conditions.

[0003] Chinese Patent No. CN222775059U discloses a spraying device for cable wrapping processing, relating to the field of cable wrapping processing technology. This invention includes: a base plate; two support plates symmetrically distributed and fixedly installed on the top of the base plate, each support plate having a fixedly installed pushing component for driving the cable forward; and a support frame fixedly installed on the top of the base plate. This invention uses ring-shaped nozzles to spray the cable onto its outer surface for comprehensive coating. After coating, the cable is further advanced into a dryer for rapid drying. The dried cable continues to move, propelled by a second pushing component, thus completing the coating of a single cable. The operation is simple and convenient, with a simple structure, shortened spraying time, greatly improving the efficiency of cable coating, reducing processing costs, and facilitating user convenience.

[0004] However, in the above technical solution, the coating is sprayed onto the outer surface of the cable only through the ring-shaped nozzles for comprehensive coating. Although the coating can be sprayed through the nozzles on the ring cylinder, its ring structure means that the sprayed coating can splash from both ends and contaminate the surrounding working environment. Utility Model Content

Each annular cylinder 4 is connected to a delivery pipe 6, one end of which is connected to an external liquid supply device. The sealing assembly is connected to both ends of the annular cylinder 4 and includes a telescopic device 7, a moving ring 8, a guide ring 9, a movable part 10, and a sealing part 11. Two telescopic devices 7 are connected to the annular cylinder 4; the telescopic devices 7 are selected, but are not limited to, electric push rods; the telescopic ends of the two telescopic devices 7 are respectively connected to two movable rings 8 located at both ends of the annular cylinder 4; the guide ring 9 is provided with radial sliding grooves 12 distributed in a circumferential array; multiple movable parts 10 are slidably connected in the sliding grooves 12; one end of the movable part 10 is connected to the sealing part 11; the axis of the movable ring 8 moves so that the movable part 10 is pushed radially through its inclined surface, so that multiple sealing parts 11 together surround the annular cylinder 4 to form a sealed space; the partition assembly is connected to the support frame 3; when the partition assembly is in use, the partition assembly sprays gas to form an air curtain to divide the frame 1 into two spaces.

[0022] Example 2

[0023] like Figures 3-4 As shown, this utility model proposes a spraying device for cable processing. Compared with Embodiment 1, this embodiment describes the detailed structure of the sealing component.

[0024] In an optional embodiment, the movable member 10 consists of an elastic member 13 and a movable block 14. The shape of the movable block 14 fits the sliding groove 12, and the elastic member 13 is disposed between the movable block 14 and the sliding groove 12. The elastic member 13 is a spring, and its two ends are respectively connected to the inner wall of the movable block 14 and the sliding groove 12.

[0025] In an optional embodiment, the seal 11 includes an arc-shaped block 15 and a sealing brush 16. The arc-shaped block 15 is connected to the movable block 14, and the sealing brush 16 is connected to the arc-shaped block 15. The sealing brush 16 can prevent paint from flying out through its fine bristles, and can conform to the outer wall of the cable through the deformable characteristics of its bristles.

[0026] In an optional embodiment, the sealing brushes 16 on adjacent arc blocks 15 are staggered; the arc blocks 15 need to be close to each other and far apart, and the staggered arrangement of the sealing brushes 16 can reduce the gaps that are generated when they are joined together.

[0027] In an optional embodiment, at least one of the two adjacent arc-shaped blocks 15 has a double-layered sealing brush 16; when the single-layer and double-layered sealing brushes 16 of the arc-shaped block 15 are spliced ​​together, a maze-like effect or a multi-layered sealing effect can be produced, reducing paint leakage.

[0028] In an optional embodiment, a sealing gasket 17 is connected to the arc plate and is disposed inside the sealing brush 16; the sealing gasket 17 is made of, but is not limited to, fluororubber, and its cross-sectional area is set to a lip-shaped structure to enhance the sealing effect.

[0029] Example 3

[0030] like Figure 2 As shown, this utility model proposes a spraying device for cable processing. Compared with Embodiment 2, this embodiment describes the detailed structure of the separating component. The separating component includes an air curtain machine 18, an air inlet hood 19, and an air outlet pipe 20. The air curtain machine 18 is connected to a notch in the support frame 3, and the air outlet of the air curtain machine 18 discharges air horizontally. The air inlet hood 19 is symmetrically arranged with the air curtain machine 18 and is connected to a notch in the support frame 3. The air inlet hood 19 is connected to the air outlet pipe 20, which is connected to external processing equipment. The air blown out by the air cup of the air curtain machine 18 is attracted by the air inlet hood 19 to form an air wall to prevent the sprayed dye from passing through, thus avoiding the danger when adding a drying structure on one side of the frame 1.

[0031] In summary, when using this utility model, the operator inserts the cable to be sprayed into one end of the equipment, allowing it to pass sequentially through the sealing assembly at one end, the inside of the annular cylinder 4, and the sealing assembly at the other end, connecting it to the external traction equipment. Both sealing assemblies are in the open state (i.e., the moving ring 8 is in the initial position, and the moving part 10 and the sealing part 11 are radially retracted). The operator activates the telescopic ends of the telescopic devices 7 at both ends through the controller or control equipment, pushing the moving ring 8 to move along the axial direction of the annular cylinder 4. The moving ring 8 is provided with inclined surfaces that contact the moving block 14. The axial movement of the moving ring 8 is achieved through the interaction of the inclined surfaces. The function is transformed into the synchronous radial movement of the moving block 14 along the radial sliding groove 12 on the guide ring 9. The moving block 14 compresses the elastic element 13, causing the arc-shaped block 15 and the sealing brush 16 to converge towards the center until they flexibly and tightly adhere to the outer surface of the cable. This forms two dynamic, adaptive sealing barriers at both ends of the annular cylinder 4, which together with the annular cylinder 4 constitute a nearly enclosed spraying space. After the sealed space is formed, the external liquid supply equipment delivers paint into the annular cylinder 4 through the delivery pipe 6, and sprays the cable surface evenly in all directions through multiple circumferentially distributed nozzles 5. Since the spraying process is carried out in a closed space, the overspray paint mist generated is effectively confined inside, fundamentally preventing the paint from polluting the working environment. At the same time, the air curtain machine 18 blows out a high-speed, uniform horizontal airflow, while the air inlet hood 19 generates negative pressure suction through the connection with the external equipment via the air outlet pipe 20. The two work together to form an effective air curtain barrier between the spraying area and the subsequent work station, physically isolating the spraying area from other potential areas.

[0032] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
