Description

Technical Field

[0001] This utility model relates to the technical field of cable pipe processing, specifically a raw material mixing device for flame-retardant cable pipes. Background Technology

[0002] Traditional cable conduits are easily combustible and release toxic fumes in fires, exacerbating the spread of fire and increasing the risk of casualties. With breakthroughs in flame-retardant material technology, new flame-retardant cable conduits have achieved self-extinguishing, low-smoke, and non-toxic properties by adding highly efficient flame retardants such as aluminum hydroxide and nitrogen and phosphorus compounds, combined with high-temperature resistant polymer substrates.

[0003] When mixing raw materials, uneven mixing can easily occur due to large differences in particle size, resulting in the finished product being prone to stratification or failing to meet performance standards. On the other hand, the discharge ports of traditional equipment are flat, which leads to residues in dead corners during discharge, resulting in material waste. Utility Model Content

[0004] The technical problem to be solved by this utility model is: to provide a raw material mixing device for flame-retardant cable pipes, which can crush raw materials that cannot pass through the filter frame through the crushing component and improve the screening efficiency of the filter frame. Through the anti-blocking component, the motor b can drive the stirring rod to mix the raw materials and drive the rubber column to impact the inclined plate, so that the mixed raw materials slide into the discharge frame.

[0005] The technical problem to be solved by this utility model is achieved by the following technical solution:

[0006] A raw material mixing device for flame-retardant cable pipes includes: a mixing chamber with two feed frames connected to the top of the mixing chamber; two crushing rollers inside the mixing chamber; baffles and inclined plates inside the mixing chamber; a crushing component inside the mixing chamber for crushing raw materials with larger particle sizes to improve mixing efficiency; the crushing component includes: crushing rollers, a motor, and a cam; and an anti-blocking component inside the mixing chamber for preventing blockage of raw materials during discharge, which could lead to equipment failure; the anti-blocking component includes: a stirring rod, a rubber column, and an inclined plate.

[0007] Preferably, a filter frame is installed inside the mixing chamber, a spring damper a is connected to the bottom of the filter frame, a discharge port is opened inside the filter frame, a vibrating rod is connected to one side of the filter frame, a mounting plate is connected to one side of the mixing chamber, a motor a is installed on the top of the mounting plate, a gear a is connected to one side of the motor a via a drive shaft, a gear b is meshed with one side of the gear a, both gear a and gear b are connected to corresponding crushing rollers via connecting rods, a gear c is meshed with one side of the gear a, a rotating rod is connected to one side of the gear c, one end of the rotating rod extends into the interior of the mixing chamber and is rotatably connected to the interior of the mixing chamber via a bearing, and a cam is installed on the outer side of the rotating rod.

[0008] Preferably, a motor b is installed at the bottom of the mixing chamber, and a rotating rod is driven and connected to the top of the motor b. A reciprocating screw is provided on the outside of the rotating rod. The rotating rod passes through the inclined plate and the baffle in sequence, extends into the mixing chamber and is connected to multiple stirring rods.

[0018] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0019] The present application will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0020] like Figures 1-5 As shown, a raw material mixing device for flame-retardant cable pipes includes a mixing box 1 with two feed frames 101 connected to the top. Two crushing rollers 102 are installed inside the mixing box 1, along with baffles 103 and inclined plates 104. A crushing assembly inside the mixing box 1 is used to crush raw materials with larger particle sizes, improving mixing efficiency. The crushing assembly includes crushing rollers 102, a motor 301, and a cam 402. An anti-blocking assembly inside the mixing box 1 is used to prevent blockage of raw materials during discharge, which could lead to equipment malfunction. The anti-blocking assembly includes a stirring rod 503, a rubber column 602, and an inclined plate 104.

[0021] In this process, the crushing roller 102, motor a301, and cam 402 in the crushing assembly are used. Motor a301 drives gears a302 and b303 to rotate, thereby driving the crushing roller 102 to rotate and crush the raw materials that cannot pass through the filter frame 2. At the same time, gear a302 drives gear c4 to rotate, causing cam 402 to continuously impact the vibrating rod 203, improving the screening efficiency of the filter frame 2. Secondly, the stirring rod 503, rubber column 602, and inclined plate 104 in the anti-clogging assembly are used. Motor b5 drives the stirring rod 503 to rotate, while the threaded block 6 moves up and down along the axial direction of the reciprocating screw 502, thereby causing the rubber column 602 to impact the inclined plate 104, causing the mixed raw materials to slide into the discharge frame 702.

[0022] The mixing chamber 1 is equipped with a filter frame 2. A spring damper a201 is connected to the bottom of the filter frame 2. A discharge port 202 is opened inside the filter frame 2. A vibrating rod 203 is connected to one side of the filter frame 2. A mounting plate 3 is connected to one side of the mixing chamber 1. A motor a301 is installed on the top of the mounting plate 3. A gear a302 is connected to one side of the motor a301 through a drive shaft. A gear b303 is meshed with one side of the gear a302. Both gear a302 and gear b303 are connected to the corresponding crushing roller 102 through connecting rods. A gear c4 is meshed with one side of the gear a302. A rotating rod 401 is connected to one side of the gear c4. One end of the rotating rod 401 extends into the mixing chamber 1 and is rotatably connected to the inside of the mixing chamber 1 through a bearing. A cam 402 is installed on the outside of the rotating rod 401.

[0023] When mixing raw materials, uneven mixing can easily occur due to large differences in particle size, resulting in stratification of the finished product or substandard performance. Motor a301 drives gear a302 to rotate. Since gear a302 meshes with gear b303, the two crushing rollers 102 rotate in opposite directions. Large particles of raw material that have not passed through the filter frame 2 fall from the feed port 202 between the two crushing rollers 102 for repeated crushing. At the same time, gear a302 drives the rotating rod 401 to rotate through meshing gear c4. The cam 402 on the rotating rod 401 periodically strikes the vibrating rod 203 as it rotates, causing the filter frame 2 to vibrate at high frequency under the elastic support of the spring damper a201, which accelerates the screening of raw materials and prevents the feed port 202 from clogging.

[0024] The mixing chamber 1 is equipped with a motor b5 at the bottom, and a rotating rod 501 is connected to the top of the motor b5. A reciprocating screw 502 is provided on the outside of the rotating rod 501. The rotating rod 501 passes through the inclined plate 104 and the baffle 103 in sequence, and extends into the mixing chamber 1 and is connected to multiple stirring rods 503. A threaded block 6 is provided on the outside of the reciprocating screw 502. A limit rod 601 is connected inside the mixing chamber 1. One end of the limit rod 601 passes through the threaded block 6. A rubber column 602 is connected to the top of the threaded block 6. The top of the rubber column 602 corresponds to the bottom of the inclined plate 104. A discharge port 7 is opened inside the baffle 103. A solenoid valve is provided inside the discharge port 7. Multiple spring dampers b701 are connected to the bottom of the inclined plate 104. A discharge frame 702 is connected to one side of the mixing chamber 1.

[0025] Working principle:

[0026] When mixing raw materials, uneven mixing can easily occur due to large differences in particle size, resulting in stratification of the finished product or substandard performance. Motor a301 drives gear a302 to rotate. Since gear a302 meshes with gear b303, the two crushing rollers 102 rotate in opposite directions. Large particles of raw material that have not passed through the filter frame 2 fall from the feed port 202 between the two crushing rollers 102 for repeated crushing. At the same time, gear a302 drives the rotating rod 401 to rotate through meshing gear c4. The cam 402 on the rotating rod 401 periodically strikes the vibrating rod 203 as it rotates, causing the filter frame 2 to vibrate at high frequency under the elastic support of the spring damper a201, which accelerates the screening of raw materials and prevents the feed port 202 from clogging.

[0027] Because the discharge ports of traditional equipment are flat during discharge, residues remain in dead corners, resulting in material waste. When the raw material falls to the stirring rod 503, the motor b5 drives the rotating rod 501, which in turn drives the stirring rod 503 to stir the raw material. After stirring, the solenoid valve inside the discharge port 7 is opened, allowing the mixed raw material to fall from the discharge port 7 onto the inclined plate 104. While the motor b5 drives the rotating rod 501 to rotate, it also drives the reciprocating screw 502 to rotate. Due to the threaded engagement between the threaded block 6 and the reciprocating screw 502, the rotation of the reciprocating screw 502 causes the threaded block 6 to move up and down along the axial direction of the reciprocating screw 502. This causes the rubber column 602 to periodically impact the bottom of the inclined plate 104. The vibration generated by the impact causes the raw material attached to the surface of the inclined plate 104 to fall off and slide into the discharge frame 702 through the tilt angle.

[0028] The above provides a detailed description of the raw material mixing equipment for flame-retardant cable pipes provided in the embodiments of this application. Specific examples have been used to illustrate the principles and implementation methods of this application. The description of the above embodiments is only for the purpose of helping to understand the technical solutions and core ideas of this application. Those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. These modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
