Description

Technical Field

[0001] This utility model relates to the technical field of cable processing, and in particular to a mixing and stirring device for cable sheathing materials. Background Technology

[0002] The mixing and blending of cable sheathing materials is a crucial step in cable production, determining the quality of the sheath. In this process, basic resin particles such as polyethylene and polyvinyl chloride are mixed with various additives, including calcium carbonate fillers, plasticizers, and lubricants. Thoroughly mixed sheathing materials ensure that cables possess good mechanical strength, flexibility, and insulation under different environments, providing a solid foundation for safe and stable transmission in power, communications, and other fields.

[0003] Although existing mixing devices can mix cable sheathing materials, for materials of different densities added to the cable sheathing materials, such as high-density fillers and low-density additives, stratification may occur during the mixing process due to factors such as centrifugal force and gravity, affecting the uniformity of mixing. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a mixing and stirring device for cable sheathing materials.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A cable sheathing material mixing and stirring device includes a tank, a stirring rod rotatably connected to the tank, a first pipe connected to one end of the tank, a cylinder connected to the other end of the first pipe, the cylinder being connected to the tank via a second pipe, an auger rotatably connected inside the cylinder, a frame connected to the tank, the frame being rotatably connected to the stirring rod, a motor installed on the frame, the motor being connected to the stirring rod, and synchronous pulleys connected to both the stirring rod and the auger, with multiple sets of synchronous pulleys driven by a synchronous belt.

[0007] Preferably, the cylinder has an opening, a baffle is placed at the opening, and a handle is connected to the baffle.

[0008] Preferably, the bottom of the tank is machined with a slope, and the lowest end of the slope faces the first tube.

[0009] Preferably, the tank body is connected to a feed inlet, and the tank body is provided with a window.

[0010] Preferably, a sliding groove is provided at one end and the other end of the opening, and a slider is connected to one end and the other end of the baffle, and the slider is slidably connected to the corresponding sliding groove.

[0011] Preferably, a rubber strip is adhered to the contact point between the baffle and the opening.

[0012] Preferably, a slide is connected to the cylinder.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. Through the coordinated arrangement of the tank, stirring rod, first pipe, cylinder, auger, second pipe, motor, synchronous pulley, and synchronous belt, when the motor drives the stirring rod to rotate within the pipe, the auger in the cylinder rotates synchronously due to the transmission between the synchronous pulley and the synchronous belt. This allows material at the bottom of the tank to enter the cylinder through the first pipe, and then be conveyed by the auger and second pipe, re-injected into the tank from the top. This cycle repeats, allowing materials of different densities to exchange positions and make full contact, reducing the likelihood of natural stratification due to gravity. For example, high-density fillers will not remain at the bottom but will continuously mix with lower-density additives above, ensuring uniform mixing.

[0015] 2. Through the cooperation between the set cylinder, opening, baffle, chute and slider, a baffle is inserted in the opening at the cylinder. When it is necessary to discharge the material in the tank, the baffle is pulled out. Because the opening position is lower than the second pipe, the material can be discharged directly at the opening during the normal material conveying process of the auger, without the need for an additional discharge device or complicated operation process, thus improving the efficiency of material discharge.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Example 1, referring to Figures 1 to 5 A mixing device for cable sheathing materials includes a tank 1, with a stirring rod rotatably connected to the tank 1. One end of the tank 1 is connected to a first pipe 3, which serves as a material conveying channel. The other end of the first pipe 3 is connected to a cylinder 4, which is connected to the tank 1 via a second pipe 6. The second pipe 6 is also an important material conveying channel, ensuring that the material conveyed from the cylinder 4 can be smoothly reinjected into the top of the tank 1, forming a material circulation flow and enhancing the mixing effect. An auger 5 is rotatably connected inside the cylinder 4. When the auger 5 rotates, it can draw material from the first pipe... Material entering cylinder 4 from body 3 is conveyed upward along the spiral blades, achieving material lifting and further mixing. A frame 7 is connected to tank 1, and the frame 7 is rotatably connected to the stirring rod 2. A motor 8 is installed on the frame 7. The model of motor 8 is selected according to actual working requirements. Motor 8 is connected to stirring rod 2. Both stirring rod 2 and auger 5 are connected to synchronous pulleys 9. Multiple sets of synchronous pulleys 9 are driven by synchronous belts 10. The transmission system composed of synchronous pulleys 9 and synchronous belts 10 can ensure that stirring rod 2 and auger 5 rotate synchronously, ensuring the coordination of material mixing and conveying process.

[0024] In this embodiment, an opening 11 is provided at the cylinder 4 for material discharge. The opening 11 is positioned lower than the second pipe 6, so that during material discharge, the auger 5 can directly discharge the material at the opening 11 during normal material conveying and rising, without the need for additional discharge devices or complex operating procedures, greatly improving the efficiency of material discharge. A baffle 12 is placed at the opening 11 to control material discharge. A handle 17 is connected to the baffle 12. A ramp 20 is machined at the bottom of the tank 1, with the lowest point of the ramp 20 facing the first pipe 3. The design of the ramp 20 helps guide the material at the bottom of the tank 1 into the first pipe 3, ensuring that the material can accurately enter the first pipe 3, providing convenient conditions for material circulation and mixing. A feed inlet 18 is connected to the tank 1, and a window 19 is provided at the tank 1. The window 19 allows the operator to observe the mixing of the material in the tank, so as to adjust the stirring parameters or perform other operations in a timely manner. Window 19 can be made of transparent high-strength glass, which has good wear resistance and corrosion resistance, ensuring the safety of the equipment without affecting observation. Both ends of opening 11 are provided with grooves 13, and both ends of baffle 12 are connected to sliders 14. Sliding sliders 14 are slidably connected to corresponding grooves 13. This cooperative design of grooves 13 and sliders 14 makes the baffle 12 more stable during opening and closing, accurately controlling the opening and closing state of opening 11. A rubber strip 15 is adhered at the contact point between baffle 12 and opening 11. The rubber strip 15 enhances the sealing between baffle 12 and opening 11. The rubber strip 15 has good elasticity and sealing properties, effectively preventing material leakage from opening 11 during stirring, ensuring a clean working environment for the stirring device, and avoiding material waste. Slides 16 are connected to the cylinder 4 to guide the material discharged from opening 11.

[0025] The working principle of this embodiment is as follows: During use, cable sheath material and various additives are added through the feed inlet 18. After addition, the motor 8 is connected to an external power source and driven to rotate. The motor 8 will drive the stirring rod 2 to rotate, and the stirring rod 2 can mix the cable sheath material with the multiple additives. At this time, with the cooperation of the synchronous pulley 9 and the synchronous belt 10, the stirring rod 2 and the auger 5 can rotate synchronously. Using the ramp 20 below the tank 1, the material at the bottom can be guided into the first pipe 3 and then into the cylinder 4. In this way, the rotation of the auger 5 can pass through the second pipe 6 and be injected again above the tank 1, which can avoid stratification and ensure the uniformity of mixing. After the mixing is completed, the handle 17 is used to lift the baffle 12, and the baffle 12 will remove the obstruction of the opening 11. When the auger 5 is conveying the material, it will flow from the opening 11 to the slide 16 for discharge.

[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
