Description

Technical Field

[0001] This utility model relates to the field of PVC steel wire hose production and manufacturing technology, specifically a high-efficiency extrusion molding machine for PVC steel wire hose. Background Technology

[0002] PVC steel wire hoses are widely used in industry, construction, agriculture and other fields due to their good flexibility, pressure resistance and corrosion resistance.

[0003] Traditional PVC steel wire hose production typically employs a segmented process: first, PVC raw materials are extruded into hoses using an extruder, and then steel wire is wound around the hose's outer wall using separate equipment. This production method has several drawbacks. For example, it requires multiple machines to work together, necessitating frequent material transfers between machines, increasing production time and labor costs. Due to segmented processing, the dimensional accuracy of the hose and the quality of the steel wire winding are difficult to guarantee, leading to problems such as loose steel wire and hose deformation. The complex production process is also detrimental to space utilization and production management for enterprises. Therefore, a high-efficiency integrated extrusion molding machine for PVC steel wire hoses is needed to improve upon these issues. Utility Model Content

[0004] To address the shortcomings of traditional PVC steel wire hose production, which typically employs a segmented process—first extruding PVC raw materials into hoses using an extruder, and then winding steel wire around the hose's outer wall using separate equipment—this method suffers from several drawbacks. For instance, it requires multiple machines working in tandem, necessitating frequent material transfers between them, increasing production time and labor costs. Furthermore, due to segmented processing, the dimensional accuracy of the hose and the quality of the steel wire winding are difficult to guarantee, leading to problems such as loose steel wire and hose deformation.

All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0025] For examples, please refer to Figures 1-4 This utility model provides a technical solution:

[0026] A high-efficiency extrusion molding machine for PVC steel wire hoses includes a main body 1, with an extrusion assembly 2 and a steel wire winding and cooling assembly 3 disposed on the top of the main body 1.

[0027] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, the extrusion assembly 2 includes a support plate 201, a driver 202 is mounted on the top of the support plate 201, a twin-screw extruder 203 is fixedly connected to the output end of the driver 202, and a molding die 204 is fixedly connected to the side of the twin-screw extruder 203. The wire winding cooling assembly 3 includes a wire winding box 301, an electronic tension controller 302 is fixedly connected to the side of the wire winding box 301, a cooling water tank 304 is provided on the side of the electronic tension controller 302, and a temperature sensor 306 is installed on the side of the cooling water tank 304. The twin-screw extruder 203 can efficiently and uniformly transport PVC raw materials, and the electronic tension controller 302 can monitor and adjust the tension of the wire in real time to ensure the uniformity and stability of the wire winding. The cooling water tank 304 and the air cooler 305 can quickly cool and shape the extruded hose. The circulating water pump 303 and the temperature sensor 306 can ensure that the temperature of the cooling water is constant and improve the cooling effect.

[0028] The forming die 204 has a multi-layer structure, with an inner layer for hose forming and an outer layer for wire winding. A hopper 205, made of aluminum alloy, is fixedly connected to the top of the twin-screw extruder 203. An air cooler 305 is installed on the side of the cooling water tank 304, and a circulating water pump 303 is installed inside the cooling water tank 304. The multi-layer structure of the forming die 204, with an inner layer for hose forming and an outer layer for wire winding, simultaneously meets the needs of hose forming and wire winding. The spiral design of the inner channel of the forming die 204 ensures that the PVC raw material receives uniform shear force during extrusion, improving the forming quality of the hose. By integrating extrusion forming and wire winding into the same equipment, automation and integration of the production process are achieved, greatly improving production efficiency, ensuring forming quality, simplifying the equipment structure, and reducing production costs, demonstrating broad application prospects.

[0029] In this embodiment, as Figure 1 and Figure 4 As shown, the main body 1 includes a support frame 101. A PLC controller 104 is fixedly connected to the side of the support frame 101. A touch screen operation interface 105 is fixedly connected inside the PLC controller 104. An adjustment key 106 is provided on the side of the PLC controller 104. A support frame 102 is fixedly connected to the bottom of the support frame 101. A pad 103 is fixedly connected to the bottom of the support frame 102.

By using the PLC controller 104 and the touch screen operation interface 105, precise control of parameters such as extrusion speed, wire winding speed, and cooling temperature can be achieved.

[0030] The working process of this utility model is as follows: When the high-efficiency PVC steel wire hose extrusion molding integrated machine designed in this scheme is working, the twin-screw extruder 203 conveys the PVC raw material from the hopper 205 to the inner channel of the molding die 204. Through the spiral-designed inner channel, the PVC raw material is subjected to uniform shear force during the extrusion process, forming a hose with a certain size and shape. The steel wire winding box 301 evenly winds the steel wire on the outer wall of the extruded hose in the outer channel of the molding die 204. The electronic tension controller 302 monitors and adjusts the tension of the steel wire in real time to ensure the uniformity and stability of the steel wire winding. After molding, the hose enters the cooling water tank 304. With the cooperation of the circulating water pump 303 and the temperature sensor 306, the cooling water maintains a constant temperature to quickly cool and shape the hose. At the same time, the air cooler 305 provides auxiliary cooling for the hose surface to further improve the cooling effect. Through the PLC controller 104 and the touch screen operation interface 105, the extrusion speed, steel wire winding speed, cooling temperature and other parameters can be precisely controlled.
