Description

Technical Field

[0001] The utility model relates to the field of hose repair, and more specifically to a glue coating machine head for double-sided adhesive fiber reinforced hose molding. Background Art

[0002] The hose is made of resin as the main raw material, with appropriate amount of fillers, color enhancers, etc. added, and is extruded by a plastic extruder and injection molded by an injection molding machine. The production of pipes and fittings is completed through processes such as cooling, curing, shaping, inspection, and packaging. The interfaces need to be coated with glue when connecting.

[0003] In the prior art, the coating thickness is achieved by adjusting the extrusion volume, rotation speed, temperature control temperature, pulling speed, etc. of the extruder, which is relatively cumbersome and difficult to control the coating thickness. Utility Model Content

[0004] The utility model aims to solve the problem that it is inconvenient to adjust the coating thickness and provides a glue coating machine head for double-sided adhesive fiber reinforced hose molding.

[0005] The technical solution of the utility model is:

[0006] A glue coating machine head for forming a double-sided adhesive fiber reinforced hose comprises a machine head body, wherein a flow channel, a core mold and a core rod are sequentially arranged in the machine head body, a mouth mold is sleeved on the head of the core mold, and the mouth mold is connected to the machine head body through a flange, and the head of the core mold is conical.

[0007] Furthermore, 1 / 4 of the length of the core mold head is tapered.

[0008] Furthermore, the inner hole of the die is a conical surface, and the degree of conicity matches that of the core die head.

[0009] Furthermore, the gap between the mouth die and the core die decreases along the advancing direction of the core die.

[0010] Beneficial effects of the utility model:

[0011] The utility model discloses a glue coating machine head for forming a double-sided adhesive fiber reinforced hose. When the core mold moves forward, the gap at the conical position of the head portion is reduced, and the coating becomes thinner. When the core mold moves backward, the gap is increased, and the coating becomes thicker. The coating thickness can be easily adjusted.

[0012] Other features and advantages of the present invention will be described in detail in the subsequent specific implementation section. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] The above and other objects, features and advantages of the present invention will become more apparent through a more detailed description of exemplary embodiments of the present invention in conjunction with the accompanying drawings, wherein the same reference numerals generally represent the same components in the exemplary embodiments of the present invention.

[0014] Figure 1 The utility model is shown in the structural diagram. DETAILED DESCRIPTION

[0015] The preferred embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although the preferred embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein.

[0016] like Figure 1 As shown, a gluing machine head for forming a double-sided adhesive fiber-reinforced hose comprises a machine head body 1, in which a flow channel 2, a core mold 3 and a core rod 4 are sequentially arranged, the head of the core mold 3 is provided with a mouth mold 5, and the mouth mold 5 is connected to the machine head body 1 through a flange 6, the head of the core mold 3 is conical; 1 / 4 of the length of the head of the core mold 3 is conical; the inner hole of the mouth mold 5 is a conical surface, and matches the degree of conicity of the head of the core mold 3.

[0017] The gap between the mouth die 5 and the core die 3 decreases along the advancing direction of the core die.

[0018] In this embodiment, the gap at the conical position of the head of the core mold is reduced when the core mold moves forward, and the coating becomes thinner, and the gap at the conical position of the head of the core mold is increased when the core mold moves backward, and the coating becomes thicker, so that the coating thickness can be easily adjusted.

[0019] The above description of various embodiments of the utility model is exemplary, not exhaustive, and is not limited to the disclosed embodiments. Many modifications and changes will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments.
