Description

Technical Field

[0001] This utility model relates to the field of hose processing technology, and in particular to a spraying device for processing release agents in hoses. Background Technology

[0002] In hose processing, the main purpose of spraying release agents (or mold release agents) is to prevent adhesion between different rubber layers or components during hose molding, vulcanization, or storage, while improving process performance and product quality.

[0003] In practical applications, since the hose is extruded, it needs to be cooled before the release agent is applied. In the prior art, it can be directly immersed in a cleaning water tank for cooling. However, after cooling with water, a water film will form on the surface of the hose. This water film will carry water into the release agent spray tank after passing through it, which will easily dilute the release agent in the tank and affect its effectiveness. Utility Model Content

[0004] The purpose of this invention is to provide a spraying device for processing release agent in rubber hoses, and to solve the problem of how to avoid the water on the surface of the rubber hose easily diluting the concentration of the release agent before spraying the release agent.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] This utility model provides a spraying device for processing release agent in rubber hoses, including a cleaning water tank for cleaning the rubber hoses and a release agent spraying tank for spraying release agent onto the surface of the rubber hoses; wherein a spray pipe is provided on the release agent spraying tank facing the rubber hoses;

[0007] A drying mechanism is provided between the cleaning water tank and the release agent spray tank;

[0008] The air-drying mechanism includes an annular seat that facilitates the passage of the hose and an air pump that supplies air into the annular seat through an air supply pipe.

[0009] In this embodiment, an air supply cavity is integrally formed inside the annular seat, and air slits or holes are uniformly opened on the inner peripheral wall of the annular seat to blow air onto the outer surface of the hose; wherein the air slits or holes can be used to uniformly blow air onto the surface of the hose, so as to achieve the purpose of drying the hose before it enters the spraying of the release agent.

[0010] Furthermore in this embodiment, the air pump is connected to the air supply chamber from multiple side wall positions of the annular seat through multiple air supply pipes; thereby achieving positive pressure air with uniform pressure at all parts of the air supply chamber.

[0011] Furthermore, in this embodiment, at least one guide roller is provided in the cleaning water tank to press the hose below the liquid surface, so that the hose can be immersed in water to achieve the purpose of cooling it, so as to better adhere the release agent.

[0012] Furthermore, in this embodiment, a release agent is injected into the release agent spray tank, and a circulation pump is connected to the bottom of the release agent spray tank through an inlet pipe. The circulation pump is connected to the spray pipe through a delivery pipe, so as to achieve uniform circulation of the release agent in the release agent spray tank.

[0013] Furthermore, in this embodiment, reserved passage slots are respectively opened on both ends of the release agent spray tank to facilitate the passage of the rubber tube. The side walls and bottom of the reserved passage slots can also be designed as arc-shaped to avoid scratching the rubber tube.

[0014] Furthermore in this embodiment, the spray pipe is a universal bamboo joint pipe or a nozzle, so as to adjust the direction and position of the spray pipe as needed.

[0015] Compared with the prior art, the beneficial technical effects of this utility model are as follows:

[0016] In this invention, a drying mechanism is installed between the cleaning water tank and the release agent spray tank. The drying mechanism dries the water film on the surface of the hose before it enters the release agent spray tank, thereby avoiding dilution of the release agent and ensuring the quality of subsequent hose vulcanization.

[0025] However, since the hose 7 is extruded, it needs to be cooled before the release agent is applied. In the prior art, it can be directly immersed in the cleaning water tank 8 for cooling. However, after cooling with water, a water film will form on the surface of the hose 7. This water film will carry water into the release agent spray tank 1 after passing through the release agent spray tank 1, which will easily dilute the release agent 4 in the release agent spray tank 1 and affect the effectiveness of the release agent.

[0028] In another embodiment, the air pump 6 can be connected to the air supply chamber 51 from multiple side wall positions of the annular seat through multiple air supply pipes 61, so as to achieve uniform air pressure in all parts of the air supply chamber 51.

[0029] refer to Figure 2A release agent 4 is injected into the release agent spray tank 1. A circulation pump 2 is connected to the bottom of the release agent spray tank 1 through an inlet pipe 21. The circulation pump 2 is connected to the spray pipe 3 through an inlet pipe 22. Reserved passage slots 11 are provided at both ends of the release agent spray tank 1 to facilitate the passage of the rubber hose 7. The spray pipe 3 is a universal bamboo-joint pipe or a nozzle.
