[0032] A reflux cavity 6 is provided in the middle of the roller body 1, one end of the reflux cavity 6 is connected to the second cavity 4, and the other end of the reflux cavity 6 passes through the first cavity 3 and is connected to the connecting component. The first cavity 3 and the reflux cavity 6 are isolated from each other.

[0033] The present invention discloses a silicone cooling roller for a wire harness tape coating machine, which consists of a roller body 1 and a roller shaft 2. A cooling component is arranged in the roller body 1, and an external component is arranged on the roller shaft 2. External cooling water is connected to the roller body 1 through the external component, so that the cooling water circulates in the cooling component in the roller body 1 to realize water cooling circulation, cools and solidifies the wire harness tape passing through the roller body 1, and improves the cooling quality and cooling efficiency; a first cavity 3 and a second cavity 4 at both ends of the cooling component are arranged in a ring shape, and the external cooling water enters the first cavity 3, and then flows along the cooling cavity 5 in the first cavity 3 after being evenly distributed, so as to reduce the temperature of the roller body 1 and improve the cooling efficiency. Efficiency; after absorbing heat, the cold water enters the second cavity 4, and then flows back to the external component through the reflux cavity 6, realizing the circulation of cooling water; the cooling cavity 5 is arranged in a plurality of pieces, which are arranged around the side of the roller body 1 close to the outer wall, expanding the heat exchange area between the cooling cavity 5 and the roller body 1, and improving the heat exchange efficiency; at the same time, the high-temperature reflux cavity 6 is arranged in the middle position of the roller body 1, reducing the influence of the cooling water after absorbing heat on the cooling effect of the roller body 1; a number of interfering flow components are arranged in the cooling cavity 5, which affect the flow of cooling water, so that the flow of cooling water in the cooling cavity 5 is turbulent, improving the heat exchange effect, thereby maintaining the cooling of the roller body 1 and improving the cooling efficiency. The present invention has a simple structure and is easy to use; the cooling cavity 5 is divided into multiple pieces, increasing the heat exchange area, and at the same time, the cooling water is turbulent in the cooling cavity 5, improving the heat exchange efficiency between the cooling water and the roller body 1, improving the cooling effect of the roller body 1 on the wiring harness tape, and improving production efficiency and production quality.

[0034] Furthermore, an isolation layer 34 is applied to the outer wall of the roller body 1 of the present embodiment, and a plurality of heat-transmitting holes 35 are provided on the isolation layer 34 to prevent the wire harness tape from directly contacting the roller body 1 , and the heat-transmitting holes 35 facilitate heat transfer.

[0035] Further optimization scheme, a plurality of cooling chambers 5 are arranged in a plurality of coaxial rings, and a plurality of cooling chambers 5 surround the reflux chamber 6 and are arranged coaxially with the reflux chamber 6. A plurality of cooling chambers 5 are arranged in a plurality of layers of rings, and the cooling chambers 5 of adjacent layers are arranged in a staggered manner, which increases the heat exchange area, improves the heat exchange efficiency, and ensures the heat exchange efficiency of the roller body 1; at the same time, the ring formed by the cooling chamber 5 surrounds the reflux chamber 6, so that the cooling water after heat exchange is collected in the reflux chamber 6 and discharged, and the heated cooling water is located at the center of the roller body 1, which reduces the influence of the heated cooling water on the outer edge of the roller body 1.

[0036] Further optimization scheme, the spoiler assembly includes a fixed block 7 arranged in the cooling cavity 5, the fixed block 7 is provided with a spoiler hole 8 facing the flow direction of the cooling water, a spoiler block 9 is slidably connected in the spoiler hole 8, and an elastic spoiler 10 is arranged between the spoiler block 9 and the bottom of the inner cavity of the spoiler hole 8. The spoiler block 9 moves telescopically under the drive of the elastic spoiler 10; when the cooling water flows through, the water pressure pushes the spoiler block 9 to move in the spoiler hole 8, compressing the elastic spoiler 10, and the elastic spoiler 10 pushes the spoiler block 9 to rebound after being compressed to the limit, thereby causing the passing cooling water to be disturbed, forming turbulence, and stirring the cooling water at the same time, so that the cooling water is mixed evenly, and it is no longer just the cooling water on the outer wall that contacts the wall surface of the cooling cavity 5, thereby improving the heat exchange efficiency.

[0037] Furthermore, the side of the spoiler block 9 facing the incoming water flow and the side of the fixed block 7 away from the spoiler block 9 are both inclined to avoid the vertical section affecting the flow, reduce the kinetic energy loss of the water flow, and reduce the wear of the roller body 1 and the cooling chamber 5.

The through holes 11 are arranged so that the front and rear of the spoiler hole 8 are connected, and when water flows into the spoiler hole 8, it can be discharged through the through holes 11, thereby avoiding the energy loss of the cooling water by the spoiler hole 8.

The water inlet box 12 and the water outlet box 13 are respectively rotatably connected to the roller shaft 2 and are sealed. The water inlet box 12 is connected to the cooling water through the water inlet pipe 14, and the reflux water in the water outlet box 13 is discharged from the water outlet pipe 15 to realize the circulation of cooling water; when in use, the external cooling water enters the water inlet box 12, then enters the water inlet cavity 16 from the water inlet hole 18, then flows into the first cavity 3 through the water inlet channel 27, and then enters the cooling cavity 5 from the first cavity 3; the cooling water in the cooling cavity 5 exchanges heat with the roller shaft 2, and then gathers into the reflux cavity 6, the cooling water in the reflux cavity 6 enters the cooling cavity 5 in the roller shaft 2 from the water outlet channel 28, then enters the water outlet box 13 from the water outlet hole 19, and finally is discharged from the water outlet pipe 15 to realize the circulation of cooling water.

[0041] Furthermore, a connecting ring 30 is threadedly connected to the roller shaft 2 of the present embodiment, and the connecting ring 30 connects the roller shaft 2 to the roller shaft 2 to facilitate maintenance and overhaul. When connected, the water inlet chamber 16 and the water inlet channel 27 are aligned, and the water outlet chamber 17 and the water outlet channel 28 are aligned. This connection method is a conventional form and will not be repeated.

[0042] Further optimization scheme, the roller body 1 is embedded with an annular heat insulation layer 20, the heat insulation layer 20 is arranged between the cooling cavity 5 and the reflux cavity 6, and the heat insulation layer 20 and the reflux cavity 6 are arranged coaxially.
