An extrusion head for cable tube production is designed, including a machine head, a molding mold, a lead pipe and a heating device. The glass fiber passes through the molding channel through the guide tube. The heating of the guide tube makes the glass fiber heat. The molten raw material wraps the glass fiber tightly during molding to form a cable tube with glass fiber arranged internally.
By tightly wrapping glass fibers into the cable tube, the bending resistance of the cable tube is significantly improved.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of cable tubes, in particular to an extrusion head for producing cable tubes. Background Art
[0002] The manufacturing process of cable protection tube usually includes the following main steps:
[0003] Raw material preparation: Select suitable raw materials, usually plastic materials such as polyethylene (PE) or polyvinyl chloride (PVC).
[0004] Extrusion molding: The raw materials are melted through an extruder and then extruded through an extrusion die.
[0005] Cooling and cutting: The extruded protective tube needs to be quickly cooled in a cooling device to solidify the plastic material. After cooling, the protective tube can be cut into the required length using a cutting machine.
[0006] However, the cable tube produced in this way has poor bending resistance, and therefore an extrusion head is urgently needed to arrange glass fibers into the cable tube to enhance the bending resistance of the cable tube. Utility Model Content
[0007] In order to solve the above technical deficiencies, the utility model provides an extrusion head for producing a cable tube, which can arrange glass fibers into the cable tube to enhance the bending resistance of the cable tube.
[0008] The utility model discloses an extrusion head for producing a cable tube, comprising a machine head, a forming die, a material guide tube and a heating device. The forming die is arranged in the machine head, a forming channel is formed between the machine head and the forming die, mounting holes are evenly arranged along the circumference at positions corresponding to the forming channel on the machine head, the mounting holes are inclined toward the material outlet direction of the forming channel, one end of the material guide tube is arranged in the mounting hole and the end portion of the material guide tube is located in the middle position of the forming channel, and a heating device is sleeved on the outer side of the end of the material guide tube away from the machine head.
[0009] When in use, the above-mentioned head is installed on the extruder, and the glass fiber is passed through the guide tube and then out of the molding channel. The diameter of the glass fiber should match the inner diameter of the guide tube, so that the glass fiber can be transported in the guide tube and the overflow of the raw material in the head can be prevented. The installation hole is inclined toward the discharge port of the molding channel, which is also conducive to preventing the overflow of the raw material in the head. The heating device heats the guide tube to heat the glass fiber entering the guide tube. Therefore, when the molten raw material is molded in the molding channel, the glass fiber can be better wrapped by the raw material and more tightly combined with the raw material. The raw material wrapped with the glass fiber is cooled on the outside to form a cable tube with glass fiber arranged inside, thereby enhancing the bending resistance of the cable tube.
[0010] In order to prevent the glass fiber from being scratched, the edges of both ends of the guide tube are rounded.
[0011] Preferably, the inner diameter of the guide tube is 1.5 mm.
[0012] The utility model provides an extrusion head for producing a cable tube, which has the beneficial effect that when the cable tube is formed, the glass fibers can be arranged in the cable tube and tightly combined with the raw materials, so that after the cable tube is cooled, a cable tube with stronger bending resistance can be obtained. BRIEF DESCRIPTION OF THE DRAWINGS
[0013] Figure 1 It is a three-dimensional diagram of embodiment 1 of the utility model;
[0014] Figure 2 This is the front view of Example 1 of the utility model. DETAILED DESCRIPTION
[0015] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

The molding die 2 is installed in the machine head 1, and a molding channel is formed between the machine head 1 and the molding die 2. Mounting holes are evenly arranged along the circumference at positions corresponding to the molding channel on the machine head 1, and the mounting holes are inclined toward the discharge direction of the molding channel. One end of the material guide tube 3 is installed in the mounting hole and the end portion is located in the middle position of the molding channel, and a heating device 4 is provided on the outer side of the end of the material guide tube 3 away from the machine head 1.
[0018] When in use, the head 1 is installed on the extruder, and the glass fiber is passed through the guide tube 3 and then out of the molding channel. The diameter of the glass fiber and the inner diameter of the guide tube 3 are both 1.5 mm, which can not only enable the glass fiber to be transported in the guide tube 3, but also prevent the overflow of the raw materials in the head 1. The heating device 4 heats the guide tube 3 to heat the glass fiber entering the guide tube 3. Therefore, when the molten raw material is molded in the molding channel, the glass fiber can be better wrapped by the raw material and more tightly combined with the raw material. The raw material wrapped with the glass fiber is cooled on the outside to form a cable tube with glass fibers arranged inside, thereby enhancing the bending resistance of the cable tube.
[0019] In order to prevent the glass fiber from being scratched, the edges of both ends of the material guide tube 3 are rounded.
