Abstract
Description
Technical Field
[0001] This utility model relates to the field of cable material preparation technology, specifically to a mixing and extrusion device for preparing cable materials. Background Technology
[0002] Cable materials (such as polyethylene, polyvinyl chloride, flame-retardant polyolefins, etc.) need to be uniformly plasticized through mixing and extrusion processes. Cable materials are generally manufactured into granules by extrusion, using a auger disc for extrusion to improve plasticization quality.
[0003] According to the patent application CN214871907 U, "A mixing and extrusion device for preparing fire-retardant cable material is described, wherein an extrusion tube is provided on one side of the feed pipe and the extrusion tube and the feed pipe are integrated into one structure; a leveling tube is provided on one side of the extrusion tube and the leveling tube and the extrusion tube are integrated into one structure; a secondary shaft is installed inside the leveling tube and the secondary shaft and the leveling tube are rotatably connected through a bearing seat; an extrusion auger is provided on the outside of the secondary shaft and the extrusion auger is welded to the secondary shaft; and an extrusion tube is installed below the leveling tube and the extrusion tube is fixedly connected to the leveling tube."
[0004] Regarding the above description, the applicant believes the following issues exist:
[0005] In the process of using this utility model, the flame-retardant additive of the production raw material is fed into the inside of the feeding pipe through the feeding hopper. The first motor is started, and the first motor drives the main shaft to rotate after being reduced in speed by the first reducer. This drives the extrusion auger to rotate, thus conveying the material from the feeding pipe to the inside of the extrusion pipe. The material is then extruded through the extrusion pipe to complete the mixing of all the raw materials. The extruded material is then extruded into the inside of the uniform material pipe. However, in actual use, this device directly feeds the raw material from the feeding hopper into the inside of the feeding pipe. During the long feeding process, since cable raw materials are composed of multiple components with large differences in density and mass, uneven mixing is likely to occur during the long feeding process. This can affect the extrusion quality during the extrusion process. Therefore, it is necessary to improve the mixing and extrusion device for cable material preparation. Utility Model Content

However, during prolonged feeding, the cable raw material contains multiple components with significant differences in density and mass, leading to uneven mixing and potentially affecting extrusion quality.

[0031] The mixing and feeding mechanism 6 includes a feeding component 61 and a mixing component 62. The mixing component 62 is located inside the feeding component 61.

[0036] Furthermore, holes are provided at corresponding positions of the slide 628 and the stirring rack 629, and the stirring rack 629 is rotatably connected in the holes, and the bevel gear 623 is rotatably connected to the inner side of the bottom of the fixed frame 622, so as to synchronously drive the stirring rack 629 to rotate.
[0037] Example 2:
[0038] Given the current limitations of existing technologies that require cutting the raw materials for extruded cables, please refer to [link / reference]. Figure 6 Furthermore, in conjunction with Embodiment 1, the cutting mechanism 8 includes a support frame 81, which is fixedly connected to the right side of the extrusion tube 7. A motor 82 is fixedly connected to the bottom of the support frame 81, and a rotary table 83 is fixedly connected to the output end of the motor 82. A pull rod 84 is rotatably connected to the top of the rotary table 83, and a cutter 85 is rotatably connected to the end of the pull rod 84 away from the rotary table 83, which facilitates the rapid cutting of the extruded cable material after extrusion.
[0039] Furthermore, a groove is provided at the position corresponding to the extrusion tube 7 and the cutter 85, and the cutter 85 is slidably connected in the groove, which facilitates the left and right movement of the cutter 85 back and forth.
[0040] In actual operation, when the device is in use, and the control systems of motors 1 (3), 2 (5), 3 (613), 4 (621), and 5 (82) are existing technologies, they can be microprocessors, programmable logic controllers (PLCs), microcontrollers, motion controllers, etc. First, before feeding, the cable raw material is transported into the insulation chamber. Then, through the set stirring and feeding mechanism 6, motor 4 (621) is started. Motor 4 (621) drives bevel gear 1 (623) to rotate, which in turn synchronously drives the limit rod 624 to rotate. This process of rotating the limit rod 624... The mixing rack 629 rotates synchronously, causing it to mix the internal cable raw materials. During mixing, the first bevel gear 623 synchronously drives the second bevel gear 625 to rotate, which in turn drives the turntable 626 to rotate. The turntable 626 then pushes the push rod 627 to move, which in turn pushes the slide 628 to move. The slide 628 then moves the mixing rack 629 downwards. As the second bevel gear 625 continues to rotate, it synchronously drives the mixing rack 629 to move up and down repeatedly, thus mixing the internal cable raw materials. 9. During the rotary stirring process, it can also move up and down reciprocally, thereby further improving the mixing effect of the internal cable raw materials. This prevents uneven mixing of the cable raw materials during subsequent long-term feeding. After mixing is completed, motor 613 is started, which synchronously drives the trapezoidal screw 614 to rotate. During the rotation of the trapezoidal screw 614, the baffle 615 moves along the guide post 616, thereby opening the bottom feed port of the insulation chamber 611. This allows the cable raw materials to fall into the extrusion tube 1 under the action of gravity. Then, motor 5 is started synchronously. Motor 25 synchronously drives the spiral conveyor blade 210 to rotate, squeezing the raw material into the extrusion tube 1. At the same time, motor 13 is started synchronously, driving the spiral conveyor blade 9 to rotate, thus evenly squeezing the extruded raw material into the outlet of the extrusion tube 1. Subsequently, it is discharged from the extrusion tube 7. During the discharge process, the cutting mechanism 8 is set up, and motor 582 is started. Motor 582 drives the rotating disk 83 to rotate, and the rotating disk 83 pulls the pull rod 84 to move. The pull rod 84 is synchronously driven, and the cutter 85 moves back and forth, thus quickly cutting the falling cable raw material.
