Technical Field

[0001] The present application relates to the technical field of hot melt hoses, and more particularly to a hot melt hose that can avoid breaking. Background Art

[0002] Hot melt hoses are also known as transfer hoses, hot melt adhesive transfer hoses, and heating hoses. The inner liner of the hot melt hose is made of imported Teflon tubing, which offers excellent flexibility, anti-stick properties, and high-temperature resistance (up to 250°C), significantly reducing carbonization. The heating element utilizes heating wire and high-temperature resistant wire, evenly wrapped around the outer wall of the hose, providing excellent insulation, uniform thermal conductivity, and high-temperature resistance. High-quality insulation materials are used to ensure the hose's thermal insulation performance.

[0003] Hot melt hoses all have a certain bending fatigue value. Bending the hot melt hoses for a long time and repeatedly beyond their maximum limit will make the hot melt hoses easy to bend during subsequent use, causing the hoses to break and cause leakage affecting the use of equipment.

[0030] Example:

[0031] The present application embodiment discloses a hot melt hose that can avoid breaking. Figure 1 、 Figure 2 、 Figure 3 and Figure 4 , including a hose body 1, both ends of the hose body 1 are symmetrically covered with shells 2, and iron joints 3 are symmetrically provided at the opposite ends of the two shells 2. The middle part of the hose body 1 is covered with a protective bag 8, and the outer wall of the protective bag 8 is made of rubber material, and the interior is filled with buffering particles to play a buffering and protective role. Polyurethane foam plastic is used here, which has the advantages of good resilience, good buffering performance and a wide applicable temperature range. Protective components are symmetrically provided at both ends of the protective bag 8.

[0032] See also Figure 1 and Figure 2 The protective assembly includes an outer plate 4, a splint 5, a threaded rod 6 and a knob 7. The two outer plates 4 are symmetrically mounted on both ends of the protective bag 8.

[0033] Through the mutual cooperation between the internal structures of the protection components, the protection bag 8 can be fixed to the outside of the hose body 1, and the hose body 1 is protected by the protection bag 8.

[0034] See also Figure 1 and Figure 2 Threaded holes that match the threaded rod 6 are symmetrically opened on both sides of the outer plate 4, and the threaded rod 6 is rotatably connected to the inside of the threaded hole.

[0035] When the threaded rod 6 rotates, it can move telescopically inside the outer plate 4.

[0036] See also Figure 1 and Figure 2 A plurality of splints 5 are symmetrically arranged at both ends of the protective bag 8 , one end of the threaded rod 6 is rotatably connected to the outer wall of the splint 5 , and the other end of the threaded rod 6 is fixedly connected to one side of the knob 7 .

[0037] When the threaded rod 6 moves, it can drive the clamping plate 5 to move synchronously, and then fix the protective bag 8 to the outside of the hose body 1.

[0038] See also Figure 3 and Figure 4 The hose body 1 is composed of a metal hose 101, a steel wire mesh 102, a heating wire 103, a glass fiber tape 104, thermal insulation cotton 105 and a woven mesh 106. The steel wire mesh 102 is sleeved on the outside of the metal hose 101.

[0039] The hose body 1 utilizes a steel mesh 102 as its skeleton, enhancing corrosion resistance. This improves the shear strength of the bond between the steel wire and the hot-melt adhesive, as well as the wettability of the hot-melt adhesive to the steel wire, thereby enhancing the overall performance of the pipe and preventing damage caused by stress concentration. This enhanced shear strength of the bond between the steel wire and the hot-melt adhesive enhances the overall performance of the pipe, making it more durable and reliable. Furthermore, the improved wettability of the hot-melt adhesive to the steel wire optimizes stress conduction between the composite layers, preventing damage caused by stress concentration and thus protecting the pipe from damage.

[0040] See also Figure 3 and Figure 4 The glass fiber tape 104 is sleeved on the outside of the steel mesh 102. A slot adapted to the heating wire 103 is opened inside the glass fiber tape 104, and the heating wire 103 is arranged inside the slot.

[0041] The heating wire 103 can be used for heating to increase the internal temperature of the hose body 1. The heating wire and the high-temperature resistant wire are evenly wound around the outer wall, and have good insulation, uniform heat conduction and high-temperature resistance.

[0042] See also Figure 3 and Figure 4 The thermal insulation cotton 105 is sleeved on the outside of the glass fiber tape 104 , and the woven mesh 106 is sleeved on the outside of the thermal insulation cotton 105 .

[0043] High-quality thermal insulation materials are used to ensure the thermal insulation performance of the hose. Rubber-plastic materials are used here. They are a mixed foam material made of high-quality rubber and polyvinyl chloride as the main materials, which is mixed, mixed, continuously extruded, heated and foamed, and cooled and cut. The rubber-plastic thermal insulation material is an elastic closed-cell foam material with the advantages of low thermal conductivity, fire retardancy, moisture resistance, vibration reduction and noise reduction, environmental protection and health, and long service life. By setting the thermal insulation cotton 105, the interior of the hose body 1 can be insulated.

[0044] The implementation principle of this embodiment is: when in use, hold the splint 5 with one hand and turn the knob 7 clockwise with the other hand to drive the threaded rod 6 to rotate. Since a threaded hole that is compatible with the threaded rod 6 is provided inside the outer plate 4, when the threaded rod 6 rotates, it will move toward the inside of the outer plate 4, and then drive the splint 5 to move, thereby driving the splint 5 to clamp the protective bag 8 and fix it to the outside of the hose body 1.

[0045] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
