Description

Technical Field

[0001] The present invention belongs to the technical field of mixing treatment of molded plastics, and particularly relates to a mixer for producing cables. Background Art

[0002] Cable sheath material is the raw material for the outer skin of cables, used to wrap around the outer part of the cable core to prevent the core from being damaged by the external environment. The production process of cable sheath material is as follows: First, raw materials such as plastic particles, rubber particles, stabilizers, and modified substances are mixed evenly in a certain proportion, then put into a mixer for heating and melting, and finally extruded into particles through an extruder.

[0003] In the prior art, most of the mixing and stirring devices for cable raw materials adopt vertical stirring machinery. The problem with vertical stirring machinery is that during the stirring process, materials with a large density will sink to the bottom and materials with a small density will float upward. The greater the density difference between different materials, the more significant this phenomenon will be. And most of the vertical stirring machinery discharges materials from the bottom, which leads to differences in the specific cost content of the mixed materials discharged in the early stage and the mixed materials discharged in the later stage when the stirring machinery transports materials to the mixer, making it difficult to ensure uniformity and not conducive to ensuring the consistency of product quality. Summary of the Invention

[0025] Please refer to Figures 1 to 7 together, and a mixer for producing cables provided by an embodiment of the present invention will be described below.

[0026] An embodiment of the present invention provides a mixer for producing cables, including a box body 10, a first spiral stirring rod 20, a second spiral stirring rod 30, and a first driving assembly 40. A stirring cavity 11 is formed inside the box body 10. The top of the stirring cavity 11 is open. One side wall of the box body 10 is provided with a discharge pipe 12 in the horizontal direction. One end of the discharge pipe 12 communicates with the stirring cavity 11, and the other end of the discharge pipe 12 is provided with a downward discharge port 13. The first spiral stirring rod 20 is a spiral stirring shaft disposed in the stirring cavity 11 and parallel to the length direction of the discharge pipe 12. The second spiral stirring rod 30 is disposed in the stirring cavity 11 and coaxially corresponds to the discharge pipe 12. The second spiral stirring rod 30 includes a first body 31, a telescopic member 32, and a second body 33 that are coaxially arranged in sequence. The first body 31 and the second body 33 have the same outer shape, except for the difference in length dimensions. Both are spiral stirring shafts, and the second body 33 is disposed adjacent to the discharge pipe 12. The telescopic member 32 is connected between the first body 31 and the second body 33 and is used to drive the second body 33 to axially extend and contract along the first body 31. When the telescopic member 32 is in a contracted state, the second body 33 is completely received in the stirring cavity 11. When the telescopic member 32 is in an extended state, the end of the second body 33 away from the first body 31 is received in the discharge pipe 12. The first driving assembly 40 is disposed on the box body 10 and is used to drive the first spiral stirring rod 20 and the second spiral stirring rod 30 to rotate around their respective central axes. During stirring, the rotation direction of the first spiral stirring rod 20 is opposite to the rotation direction of the second spiral stirring rod 30.

[0027] Compared with the prior art, the beneficial effects of a mixer for producing cables provided by an embodiment of the present invention are as follows: A mixer for producing cables provided by an embodiment of the present invention includes a box body 10, a first spiral stirring rod 20, a second spiral stirring rod 30, and a first driving assembly 40. The box body 10 has a stirring cavity 11, and a discharge pipe 12 is arranged on the side wall of the box body 10. The first spiral stirring rod 20 and the second spiral stirring rod 30 are rotatably arranged in the stirring cavity 11 and can stir the materials. After the stirring is completed, the telescopic member 32 extends, and the second spiral stirring rod 30 extends into the discharge pipe 12. At this time, the second spiral stirring rod 30 can play a role in conveying the materials, and can convey the materials in the stirring cavity 11 to the discharge pipe 12 and discharge them from the discharge port 13.

[0028] The box body 10 in the embodiment of the present invention adopts a horizontal design, and the discharge pipe 12 is located on one side of the box body 10. In this way, on the one hand, compared with vertical stirring machinery, the height of the box body 10 can be set lower, reducing the distribution difference of materials with different densities in height. On the other hand, the first spiral stirring rod 20 and the second spiral stirring rod 30 are used for stirring, and the disturbance effect on the materials is good, which also helps to mix the materials with different densities evenly. On the other hand, the side discharge method is adopted, and the proportion of each component of the materials in the front and back batches will not change greatly during discharging, and the consistency of the products produced in the front and back batches is higher.

[0029] The box body 10 adopts a horizontal box body 10, which is relatively low in height and long in axial length. The cross-section of the box body 10 can be square, semi-cylindrical, trapezoidal, etc. The discharge pipe 12 is located at one end of the box body 10. During stirring, the discharge port 13 is closed to prevent material leakage. When discharging is required after stirring, the discharge port 13 is opened, and the second spiral stirring rod 30 extends into the discharge pipe 12. As the second spiral stirring rod 30 extends, when the second spiral stirring rod 30 rotates, it can convey the materials from the stirring cavity 11 to the discharge pipe 12 and discharge them from the discharge port 13. The discharged materials can be conveyed to subsequent processes for operations such as heating and granulation.

[0030] The first spiral stirring rod 20, the first body 31, and the second body 33 can be spiral blades, and a steel pipe is used as the shaft body in the center of the spiral blades. The first driving assembly 40 is used to drive the first spiral stirring rod 20 and the second spiral stirring rod 30 to rotate at an appropriate speed and direction. The first driving assembly 40 can include a plurality of motors corresponding to the first spiral stirring rod 20 and the second spiral stirring rod 30 one by one, or the first driving assembly 40 can also include one motor, and one motor drives the first spiral stirring rod 20 and the second spiral stirring rod 30 to rotate simultaneously through a gear transmission group.

[0031] Please refer to Figures 1 to 3 and Figure 6, in some possible embodiments, the mixer for producing cables further includes a dust-proof cover plate 50. The dust-proof cover plate 50 is disposed on the opening of the mixing chamber 11. An inlet 51 is formed on the dust-proof cover plate 50, and a closable cover 52 is provided on the inlet 51.

[0032] During stirring, the cover 52 is in a closed state, which can prevent impurities from entering. When raw materials need to be added, the cover 52 is opened, and the raw materials are added through the inlet 51.

[0033] In actual production, the raw materials may be affected by factors such as air humidity, the materials provided by suppliers, and the storage environment and become damp. After the damp raw materials enter the internal mixer, the evaporation of moisture will cause bubbles, and the compactness of the raw material mixture and the product quality of the outer wall of the wire and cable cannot be guaranteed.

[0034] To solve the problem that the raw materials may contain moisture, please refer to Figures 1 to 3 , and Figure 6 , in some possible embodiments, an electric heating wire is provided on the inner wall of the mixing chamber 11. The box body 10 is provided with a water receiving tray 14 around the mixing chamber 11. The water receiving tray 14 is annular and is provided with a water storage tank along its circumferential direction. The opening of the water storage tank faces upward, and at least one drain hole communicating with the outside is formed on the water storage tank; the dust-proof cover plate 50 has a spire shape with a higher middle and lower sides. The lower end of the dust-proof cover plate 50 is located above the water storage tank.

[0035] During the stirring process, due to the friction between the materials and the heat generated by the electric heating wire, the moisture that may be contained in the materials will evaporate. After the water vapor rises in the mixing chamber 11 and contacts the dust-proof cover plate 50, it will be liquefied into liquid water and slide down along the inclined plane into the water storage tank. The drain hole of the water storage tank is communicated with a drain pipe 141, which can drain the water in time. One or more drain holes and drain pipes 141 can be provided according to needs.

[0036] Please refer to Figures 1 to 3 , in some possible embodiments, a condensate water pipe 53 is provided on the dust-proof cover plate 50. The condensate water pipe 53 is coiled and covers the surface of the dust-proof cover plate 50. One end of the condensate water pipe 53 is communicated with a water source, and the other end is communicated with the drain pipe 141. The condensate water pipe 53 is used to reduce the temperature of the dust-proof cover plate 50 so that the water vapor can be liquefied in time. [[ID=!22]]

On the one hand, the support seat 34 can seal the discharge pipe 12 to prevent the unmixed materials from entering the discharge pipe 12, and on the other hand, it also plays a supporting role to support the end of the second body 33; when discharging, the telescopic member 32 is in an extended state, and the support seat 34 is located on the side of the discharge port 13 away from the second body 33, and the materials can be smoothly discharged.
