Description

Technical Field

[0001] The invention relates to the technical field of cable material production, and in particular to a feeding device and a homogeneous mixing process for producing low-smoke halogen-free flame-retardant cable material. Background Art

[0002] Low-smoke halogen-free flame-retardant cable material is a special cable material widely used in the fields of electricity, communications, rail transit, etc. It is characterized by low smoke production during combustion and the absence of toxic halogen compounds. Therefore, it has the advantages of environmental protection and safety. In practical applications, the production of low-smoke halogen-free flame-retardant cable materials usually requires mixing multiple raw materials in a certain proportion, including polymer substrates, flame retardants, fillers and other functional additives. These raw materials are of many types and have high requirements for the proportion. In the production process, it is necessary to ensure uniform mixing to achieve excellent electrical properties, mechanical properties and flame retardant effects.

[0003] In the prior art, a Chinese patent document with publication number CN216400158U proposes a raw material mixing device for low-smoke halogen-free flame-retardant insulation materials for cables, including a storage mechanism, a mixing mechanism and a cleaning mechanism. The storage mechanism includes a storage cylinder, and a feeding port is opened at the top of the storage cylinder. Although the technology further limits the position of the connecting rod by using a limit block and a limit groove in combination, so that the raw material mixing device for low-smoke halogen-free flame-retardant insulation materials for cables does not affect the production speed and reduce the workload of the staff, the technology is consistent with the traditional method in that before the traditional equipment mixes the materials, the feeding process needs to be completed first. However, due to the wide variety of raw materials for low-smoke halogen-free flame-retardant cable materials and strict requirements on the ratio, the traditional feeding process usually relies on manual measurement and batching, which is prone to inaccurate raw material ratios due to operational errors, thereby affecting the performance stability of the cable materials and the consistency of product quality. In addition, manual batching is inefficient and has high operating costs, making it difficult to meet the needs of efficient production. At the same time, raw materials often stick to the wall and remain inside the equipment during the mixing process, which not only increases the complexity and cost of cleaning work, but also leads to waste of raw materials, further reducing the economic efficiency of production and limiting process improvements and overall efficiency improvements. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a feeding device and a homogeneous mixing process for producing low-smoke halogen-free flame-retardant cable materials to solve the problems of inaccurate proportions during feeding and easy attachment of raw materials to the wall during mixing in the existing devices.

[0013] A homogeneous mixing process for producing low-smoke halogen-free flame-retardant cable materials, using the above-mentioned feeding device for producing low-smoke halogen-free flame-retardant cable materials, comprises the following steps: S1: First, multiple raw material particles are placed inside the storage cylinder. At this time, multiple raw materials will be input into the expansion cylinder through the output cylinder for pre-storage. At this time, when the rotating disk drives the expansion cylinder to rotate to one side of the arc groove, the bottom cover will be away from the bottom of the expansion cylinder to enable multiple raw materials to be quantitatively input into the alignment cylinder; S2: Then the rotating motor is started to drive the propeller to rotate, so that the various raw materials are mixed. During the mixing process, the various raw materials fall to the top of the conical plate by gravity for accumulation. At this time, the raw materials press the conical plate down by gravity, and the bolt will be stuck in the positioning hole for positioning. At this time, the conical plate is just away from the inside of the mixing cylinder. At this time, the mixed raw material particles will flow out from the gap between the conical plate and the mixing cylinder to the inside of the regulating cylinder; S3: Then, by rotating the screw rod, the movable ring is moved up and down to adjust the size of the gap between the disc and the bottom of the regulating cylinder, thereby adjusting the size of the output flow of the raw material particles from the regulating cylinder; S4: Finally, the mixed raw material particles fall into the interior of the collecting barrel and are output from the interior of the discharging box. At the same time, when a part of the raw materials are mixed and output, the pull rope is pulled to cause the trapezoidal block to squeeze the latch, causing the rebound spring to pull the conical plate back to the interior of the mixing barrel for next use.

[0014] Compared with the prior art, the present invention has at least the following beneficial effects: In the above scheme, by setting up an output component, through the combination of a metering cylinder and a rotating disk, a variety of raw materials can be accurately measured and output, ensuring that the ratio of each raw material meets the process requirements, greatly improving the accuracy of the ingredients, thereby effectively ensuring the consistency and stability of product quality. At the same time, by equipping multiple independent storage cylinders, various types of raw materials can be processed at the same time to meet the needs of different cable material production processes. It has a wide range of applicability, especially in the production of complex formulas. The device can simplify the operating process and improve production efficiency.

[0015] By setting up a mixing component, a propeller-type mixing component is used inside the mixing barrel, combined with a conical plate design, the uniformity of the raw materials during the mixing process is ensured. At the same time, the raw materials are rotated downward when they are mixed, and the problem of dead corner accumulation inside the mixing barrel is avoided, making the mixing more thorough, and effectively improving the efficiency of subsequent production processes. At the same time, when the raw materials accumulate on the top of the conical plate, the conical plate presses down, causing the raw materials to flow out from the gap between the conical plate and the mixing barrel, and the conical plate automatically rebounds using a rebound spring, causing the raw materials on the top of the conical plate to be bounced off. At the same time, when the cleaning barrel rebounds, the raw materials stuck to the inner wall of the mixing barrel are scraped upward through the diamond holes, thereby avoiding the problem of raw materials accumulating on the inner wall of the mixing barrel that is difficult to clean.

[0016] By setting an adjustment component and rotating the screw, the movable ring can shrink or expand the disc, and the gap between the disc and the adjustment cylinder can be expanded or reduced, so as to flexibly adjust the output flow of the mixed raw materials to meet different production needs, so that the user can adjust the output speed according to the actual production situation, improve the versatility and adaptability of the equipment, and at the same time, the disc is made of rubber. When the mixed material falls to the top of the disc, the elasticity is used to make the raw materials jump, so as to promote the secondary mixing of the raw materials, and promote the mixing of the raw materials more evenly.

[0022] like Figures 1 to 9As shown, an embodiment of the present invention provides a feeding device for producing low-smoke halogen-free flame-retardant cable materials, including an adjusting cylinder 1, a mixing cylinder 27 is fixedly connected to the top of the adjusting cylinder 1, an output assembly for quantitatively outputting a variety of raw materials is arranged on the top of the mixing cylinder 27, the output assembly includes a plurality of material storage cylinders 2, a support frame 3 is fixedly connected to one side of the plurality of material storage cylinders 2, an output end of the material storage cylinder 2 is connected to an output cylinder 4, the output ends of the plurality of output cylinders 4 are in contact with the top of a rotating disk 5, a rotating rod 13 is fixedly connected to the bottom of the middle of the rotating disk 5, a plurality of quantitative cylinders 6 are fixedly connected to the outer edge of the bottom of the rotating disk 5 in a circular shape, a connecting column 14 is slidably connected to the outside of the top of the rotating rod 13, and the top of the connecting column 14 rotates An adjusting disk 8 is clamped, and the interior of the adjusting disk 8 is circular and fixedly connected with multiple expansion cylinders 7, the bottom of the expansion cylinder 7 is movably connected with a bottom cover 9, the top of the connecting column 14 is externally fixedly connected with a chassis 15, and the interior of the chassis 15 is provided with an arc groove 16, the bottom end of the rotating rod 13 is rotatably connected to the top of the adjusting cylinder 1, the interior of the mixing cylinder 27 is provided with a mixing component for mixing multiple raw materials and preventing the raw materials from hanging on the wall, the interior of the adjusting cylinder 1 is provided with an adjusting component for adjusting the output flow rate of the mixed raw materials, and a collecting cylinder 66 is installed at the bottom of the adjusting cylinder 1, the diameter of the top opening of the collecting cylinder 66 is larger than the diameter of the bottom opening of the adjusting cylinder 1, and one side of the collecting cylinder 66 is connected to a discharge box 45.

[0023] By setting up an output component, through the combination of a metering cylinder 6 and a rotating disk 5, a variety of raw materials can be accurately measured and output, ensuring that the ratio of each raw material meets the process requirements, greatly improving the accuracy of the ingredients, and thus effectively ensuring the consistency and stability of product quality. At the same time, by equipping a plurality of independent storage cylinders 2, various types of raw materials can be processed at the same time to meet the needs of different cable material production processes. It has a wide range of applicability, especially in the production of complex formulas. The device can simplify the operating process and improve production efficiency.

[0024] like Figures 1 to 5As shown, a plurality of alignment holes are provided inside the rotating disk 5, and the positions of the alignment holes correspond to the positions of the output ports of the output cylinder 4, the number of the plurality of output cylinders 4 is equal to the number of the plurality of quantitative cylinders 6, the positions of the output ports of the output cylinder 4 correspond to the positions of the input ports of the quantitative cylinder 6, the number of the plurality of quantitative cylinders 6 is equal to the number of the plurality of expansion cylinders 7, and the inner parts of the tops of the plurality of expansion cylinders 7 are slidably connected to the outer parts of the bottoms of the quantitative cylinders 6, the diameter of the bottom cover 9 is adapted to the diameter of the expansion cylinder 7, one side of the bottom of the expansion cylinder 7 is fixedly connected to an L-shaped plate 10, and one side of the bottom cover 9 is fixedly A lever plate 11 is fixedly connected thereto, one end of the L-shaped plate 10 away from the expansion cylinder 7 is rotatably connected to the middle part of the lever plate 11 through an axis, and a sliding bolt 12 is fixedly connected to the top of one end of the lever plate 11 away from the bottom cover 9, and the top of the sliding bolt 12 is slidably connected to the bottom of the chassis 15, and the top of the mixing cylinder 27 is connected to the alignment cylinder 25, and the position of the alignment cylinder 25 is located at the bottom of one side of the arc groove 16. When the bottom cover 9 rotates to one side of the arc groove 16, the position of the bottom cover 9 corresponds to the position of the alignment cylinder 25, and the diameter of the top opening of the alignment cylinder 25 is larger than the diameter of the bottom cover 9.

[0025] By means of the metering cylinder 6 and the expansion cylinder 7, when quantitatively outputting a variety of raw materials, the various raw materials are first placed in the storage cylinder 2, and then the various raw materials will be input from the inside of the output cylinder 4 into the inside of the metering cylinder 6, and stored in the inside of the expansion cylinder 7. At this time, the raw materials will fill the inside of the metering cylinder 6 and the expansion cylinder 7, and then the rotating rod 13 is rotated to cause the rotating disk 5 to rotate with the metering cylinder 6, and at the same time, the expansion cylinder 7 will rotate with the adjusting disk 8, and at this time, the sliding bolt 12 on one side of the bottom cover 9 will slide at the bottom of the chassis 15, and then when the sliding bolt 12 rotates to the arc groove 16 inside the chassis 15, the raw materials will press the bottom cover 9 by gravity, causing the bottom cover 9 to move downward away from the bottom of the expansion cylinder 7, and at the same time, the other end of the bottom cover 9 The sliding bolt 12 is inserted into the interior of the arc groove 16, and the raw material will be output from the interior of the expansion cylinder 7. At the same time, when the metering cylinder 6 and the expansion cylinder 7 are away from the output port of the output cylinder 4, the alignment hole inside the rotating disk 5 will be away from the output port of the output cylinder 4, thereby enabling the quantity inside the metering cylinder 6 and the expansion cylinder 7 to be controlled, while avoiding the problem of continuous output of the output cylinder 4, thereby achieving the effect of quantitative output of raw materials. At the same time, when multiple expansion cylinders 7 are rotated to one side of the arc groove 16 in turn, they are output in this way, thereby achieving the effect of quantitative output of multiple raw materials in turn. It should be noted here that the size of the metering cylinder 6 and the expansion cylinder 7 can be changed according to the required proportion of each raw material, thereby achieving the effect of accurately controlling the proportion of each raw material.

[0026] like Figures 1 to 5As shown, a support column 17 is fixedly connected to the top of the adjusting cylinder 1, one side of the top of the supporting column 17 is rotatably connected to the outside of the rotating rod 13, and a fixed block 18 is fixedly connected to the other side of the top of the supporting column 17. A rack 19 is internally slidably engaged with one side of the fixed block 18, and the top of the rack 19 is fixedly connected to one side of the bottom of the connecting column 14, and one side of the rack 19 is meshed with a gear 20. One side of the gear 20 is fixedly connected to a first adjusting wheel 23 through an axis, and the gear 20 is connected to the first adjusting wheel 23. The first bracket 21 is rotatably connected to the outside of the axis, and a first positioning disk 22 is fixedly connected to one side of one end of the first bracket 21, and the other end of the first bracket 21 is fixedly connected to one side of the fixing block 18. The interior of the first positioning disk 22 is circular and equidistantly provided with a plurality of jacks, and the interior of the first adjusting wheel 23 is slidably connected with a first plug rod 24, and the position of the first plug rod 24 corresponds to the position of the jack, and the diameter of the first plug rod 24 matches the diameter of the jack.

[0027] By setting the rack 19 and the connecting column 14, the internal capacity of the expansion cylinder 7 and the quantitative cylinder 6 can be adjusted. When adjusting, by rotating the first adjusting wheel 23, the gear 20 drives the rack 19 to move downward. At this time, by setting the bottom of the adjusting disk 8 and the top of the connecting column 14 to rotate and engage, the connecting column 14 will move the adjusting disk 8 downward, and the expansion cylinder 7 will move the bottom cover 9 downward, thereby increasing the internal capacity of the quantitative cylinder 6 and the expansion cylinder 7, so that more raw materials can be placed in the quantitative cylinder 6 and the expansion cylinder 7. At the same time, by setting the adjusting disk 8 and the connecting column 14, the internal capacity of the quantitative cylinder 6 and the expansion cylinder 7 can be increased. The top of the connecting column 14 is rotated and locked, so that the adjusting disk 8 can move with the movement of the connecting column 14, so that the sliding bolt 12 can always fit the bottom of the chassis 15, and it is also convenient for the rotation of the adjusting disk 8. After the adjustment is completed, the first plug 24 is passed through the inside of the first adjusting wheel 23 and connected to the jack inside the first positioning disk 22, so that the position of the connecting column 14 is fixed. At the same time, it should be noted that in the later stage, when the capacity of the metering cylinder 6 and the expansion cylinder 7 is larger, it can be adjusted by the motor driving gear 20, thereby avoiding the trouble of manual adjustment.

[0028] like Figures 1 to 5As shown, the outside of the bottom end of the rotating rod 13 is fixedly connected with a driven wheel 53, one side of the driven wheel 53 is meshedly connected with a driving wheel 54, the bottom of the driving wheel 54 is rotatably connected to the top of the adjusting cylinder 1 through an axis, the top of the driving wheel 54 is fixedly connected with a second adjusting wheel 57 through an axis, the outside of the axis connecting the driving wheel 54 and the second adjusting wheel 57 is rotatably connected with a second bracket 55, one side of one end of the second bracket 55 is fixedly connected with a second positioning disk 56, the other end of the second bracket 55 is fixedly connected to the top of the adjusting cylinder 1, an azimuth hole is provided on the top of the second positioning disk 56, the inside of the second adjusting wheel 57 is slidably connected with a second plug rod 58, the position of the second plug rod 58 corresponds to the position of the azimuth hole, and the diameter of the second plug rod 58 matches the diameter of the azimuth hole.

[0029] By means of the second positioning disk 56 and the azimuth hole, when the rotating disk 5 is rotated, the second adjusting wheel 57 is rotated first, prompting the second adjusting wheel 57 to rotate with the driving wheel 54, and at the same time the driving wheel 54 prompts the driven wheel 53 to rotate with the rotating rod 13, thereby prompting the metering cylinder 6 and the expansion cylinder 7 to rotate and output the raw materials quantitatively. At the same time, by means of the azimuth hole, repeated output of different raw materials can be avoided. The azimuth hole serves as a reference point. After the second adjusting wheel 57 rotates one circle, the second insertion rod 58 will return to the position of the azimuth hole again, thereby avoiding the problem of repeated output of different raw materials. It should be noted here that when the capacity of the metering cylinder 6 and the expansion cylinder 7 becomes larger in the later stage, a motor can be used to drive the driving wheel 54 to rotate, thereby avoiding the problem of the capacity of the metering cylinder 6 and the expansion cylinder 7 being difficult to control manually.

[0030] like Figures 1 to 9 As shown, the mixing assembly includes a rotating shaft 28 rotatably connected to the middle of a mixing barrel 27, a propeller 29 is fixedly connected to the outside of the rotating shaft 28, a rotating motor 26 is fixedly connected to the top of the mixing barrel 27, an output end of the rotating motor 26 penetrates the top of the mixing barrel 27 and is fixedly connected to the top of the rotating shaft 28, a cleaning barrel 30 is slidably connected to the inside of the mixing barrel 27, the inside of the cleaning barrel 30 is penetrated by a plurality of rhombus-shaped holes, and the plurality of rhombus-shaped holes are arranged in a ring-shaped manner, two by two, and equidistantly distributed throughout the inside of the cleaning barrel 30, and the outside of the cleaning barrel 30 is connected to the mixing barrel 27. The inner wall of the cylinder 27 fits together, and a plurality of rebound springs 65 are fixedly connected to the top of the cleaning cylinder 30. The top of the rebound spring 65 is fixedly connected to the bottom of the top of the mixing cylinder 27. The bottom of the cleaning cylinder 30 is circular and equidistantly fixedly connected with a plurality of arc blocks 32. The bottom of the arc blocks 32 is fixedly connected with a conical plate 31. The diameter of the bottom of the conical plate 31 is adapted to the specification size of the internal space of the mixing cylinder 27. A slip ring 33 is fixedly connected to the middle of the conical plate 31. The inside of the slip ring 33 is slidably connected to the outside of the bottom of the rotating shaft 28.

[0031] By setting the mixing component, the propeller 29 type mixing component is adopted inside the mixing barrel 27, and the design of the conical plate 31 is combined to ensure the uniformity of the raw materials during the mixing process. At the same time, the raw materials are rotated downward when the raw materials are mixed, and the problem of dead corner accumulation inside the mixing barrel 27 is avoided, so that the mixing is more thorough, and the efficiency of the subsequent production process is effectively improved. At the same time, when the raw materials are accumulated on the top of the conical plate 31, the conical plate 31 is pressed down, and the raw materials are caused to flow out from the gap between the conical plate 31 and the mixing barrel 27. After that, the conical plate 31 automatically rebounds by using the rebound spring 65, so that the raw materials on the top of the conical plate 31 are bounced off. At the same time, when the cleaning barrel 30 rebounds, the raw materials stuck to the inner wall of the mixing barrel 27 are scraped upward through the diamond holes, thereby avoiding the problem of raw materials accumulating on the inner wall of the mixing barrel 27 and being difficult to clean. When multiple raw materials are output from the inside of the expansion barrel 7, the raw materials will fall into the inside of the alignment barrel 25 in turn, and enter the inside of the mixing barrel 27 at the same time. At this time, by starting the rotating motor 26, the rotating shaft 28 is caused to carry the spiral The propeller 29 rotates, thereby causing the propeller 29 to mix the various raw materials. At the same time, the mixed raw materials will move downward due to gravity and the rotation of the propeller 29, and fall onto the top of the conical plate 31 for accumulation. When a certain amount of mixed materials are accumulated on the top of the conical plate 31, the conical plate 31 will pull the cleaning cylinder 30 and the rebound spring 65 downward. When the cleaning cylinder 30 descends, the raw materials stuck to the inside of the mixing cylinder 27 will be scraped off. At the same time, when the conical plate 31 moves downward, the slip ring 3 3 will drive the placement cylinder 38 to move downward. At this time, when the bolt 40 moves to one side of the positioning hole 37, the bolt 40 automatically rebounds using the positioning spring 39, prompting one end of the bolt 40 to be stuck in the positioning hole 37. At this time, the position of the conical plate 31 is fixed, and the conical plate 31 is away from the bottom of the mixing cylinder 27. At this time, the mixed material will flow out from the gap between the conical plate 31 and the mixing cylinder 27. At the same time, the arc block 32 is set to be an arc, which can avoid the problem of the mixed material being stuck at the arc block 32.

[0032] like Figures 1 to 9As shown, the outer rotation clamp at the bottom of the rotating shaft 28 is connected with a connecting ring, one side of the connecting ring is fixedly connected with a positioning box 34, the top of the positioning box 34 passes through the inside of the conical plate 31, one side of the slip ring 33 is fixedly connected with a placing cylinder 38, the outside of the placing cylinder 38 is fixedly connected with a baffle 35, the outside of the baffle 35 is slidably connected with one side of the positioning box 34, and the length of the baffle 35 is greater than the length of the positioning box 34, the inside of the placing cylinder 38 is fixedly connected with a positioning spring 39, one end of the placing cylinder 38 is slidably connected with a clamping bolt 40, and the positioning spring One end of 39 away from the placement tube 38 is fixedly connected to one end of the bolt 40, the interior of the alignment box 34 is fixedly connected to the abutment plate 36, and a positioning hole 37 is provided inside the bottom of the abutment plate 36. A trapezoidal block 42 is slidably connected between the alignment box 34 and the abutment plate 36, and a return spring 41 is fixedly connected to the top of the trapezoidal block 42. The top of the return spring 41 is fixedly connected to the top of the alignment box 34, and a pull rope 43 is fixedly connected to the bottom of the trapezoidal block 42. The other end of the pull rope 43 is fixedly connected to the outside of the collecting tube 66 through a plurality of pulleys.

[0033] By setting the trapezoidal block 42 and the pull rope 43, when the mixed material is output later, the pull rope 43 can be pulled to cause the trapezoidal block 42 to move downward. When one side of the trapezoidal block 42 moves to one side of the positioning hole 37, the trapezoidal block 42 will squeeze the bolt 40 to shrink. At the same time, the cleaning cylinder 30 and the conical plate 31 will automatically rebound through the rebound spring 65, thereby causing the conical plate 31 to return to the inside of the mixing cylinder 27 again. At the same time, when the cleaning cylinder 30 returns to its position, the diamond holes inside the cleaning cylinder 30 will scrape the inner wall of the mixing cylinder 27 again, thereby achieving the effect of cleaning the inner wall of the mixing cylinder 27.

[0034] like Figures 6 to 9As shown, the adjustment assembly includes a positioning column 46 rotatably clamped at the bottom end of the rotating shaft 28, a fixing rod 47 is fixedly connected to one side of the positioning column 46, and one end of the fixing rod 47 away from the positioning column 46 is fixedly connected to the inner wall of the adjusting cylinder 1, and a disk 48 is fixedly connected to the outside of the positioning column 46, and the material of the disk 48 is rubber. A screw 49 is rotatably clamped at the bottom end of the positioning column 46, and the external thread of the screw 49 is connected to a movable ring 50. The outside of the movable ring 50 is rotatably connected to a plurality of connecting rods 51 through an axis in a circular and equidistant manner. The outside of the bottom of the positioning column 46 is rotatably connected to a plurality of support rods 52 through an axis in a circular and equidistant manner. The end of the connecting rod 51 away from the movable ring 50 is rotatably connected to the middle part of the support rod 52 through an axis, and the top of the support rod 52 is fixedly connected to the bottom of the disk 48. The diameter of the bottom of the disk 48 is smaller than the specification size of the internal space of the adjusting cylinder 1. The screw 49 When rotating, the movable ring 50 expands or shrinks the disc 48, and the bottom end of the screw 49 passes through the bottom of the collecting cylinder 66 and is fixedly connected to the first pulley 44. One side of the first pulley 44 is connected to the second pulley 61 through a belt drive. The bottom of the second pulley 61 is rotatably connected to a fixing column 59, and the bottom end of the fixing column 59 is installed on the ground. The top of the second pulley 61 is fixedly connected to a third adjusting wheel 63 through an axis. The third adjusting wheel 63 is connected to the second pulley 61 and is rotatably connected to the third bracket 60 on the outside of the axis. The top of one end of the third bracket 60 is fixedly connected to a third positioning disk 62, and the other end of the third bracket 60 is fixedly connected to the outside of the fixing column 59. A plurality of adjusting holes are provided on the top of the third positioning disk 62, and the inside of the third adjusting wheel 63 is slidably connected to a third plug rod 64, and the diameter of the third plug rod 64 matches the diameter of the adjusting hole.

[0035] By means of the setting adjustment component, the screw 49 is rotated to cause the movable ring 50 to contract or expand with the disc 48, thereby causing the gap between the disc 48 and the adjustment barrel 1 to be expanded or reduced, thereby achieving the output flow rate of the mixed raw materials to be flexibly adjusted, thereby adapting to different production needs, enabling users to adjust the output speed according to actual production conditions, and improving the versatility and adaptability of the equipment. At the same time, the disc 48 is set to be made of rubber material. When the mixed material falls to the top of the disc 48, the elasticity is used to cause the raw material to jump, thereby causing the raw material to be mixed for the second time, thereby causing the raw material to be mixed more evenly. When adjusting the flow rate, when the mixed material flows out from the bottom of the mixing barrel 27, it will fall into the interior of the adjustment barrel 1. At this time, by rotating the third adjustment The wheel 63 rotates with the second pulley 61, and the first pulley 44 will rotate with the screw 49, thereby prompting the movable ring 50 to move using the threaded action. At this time, when the movable ring 50 moves downward, the connecting rod 51 will move downward with the support rod 52, and at this time, multiple support rods 52 will move downward with the disc 48, thereby increasing the distance between the disc 48 and the bottom of the adjusting cylinder 1, thereby increasing the flow rate of the mixed material output, thereby adapting to different production needs. At the same time, through the third positioning disk 62, when the position adjustment of the disc 48 is completed, the third insertion rod 64 is passed through the interior of the third adjusting wheel 63 and connected to the adjustment hole on the top of the third positioning disk 62, thereby prompting the position of the disc 48 to be fixed, thereby facilitating the output of the mixed material.

[0036] The embodiment of the present invention further provides a homogeneous mixing process for producing low-smoke halogen-free flame-retardant cable materials, which uses the above-mentioned feeding device for producing low-smoke halogen-free flame-retardant cable materials, and includes the following steps: S1: First, multiple raw material particles are placed inside the storage barrel 2. At this time, multiple raw materials will be input into the expansion barrel 7 through the output barrel 4 for pre-storage. At this time, when the rotating disk 5 drives the expansion barrel 7 to rotate to one side of the arc groove 16, the bottom cover 9 will move away from the bottom of the expansion barrel 7 to enable multiple raw materials to be quantitatively input into the alignment barrel 25; S2: Then the rotating motor 26 is started to drive the propeller 29 to rotate, so that the various raw materials are mixed. During the mixing process, the various raw materials fall to the top of the conical plate 31 by gravity and are accumulated. At this time, the raw materials press the conical plate 31 down by gravity, and the bolt 40 will be stuck in the positioning hole 37 for positioning. At this time, the conical plate 31 is just away from the inside of the mixing barrel 27. At this time, the mixed raw material particles will flow out from the gap between the conical plate 31 and the mixing barrel 27 to the inside of the regulating barrel 1; S3: Then, by rotating the screw 49, the movable ring 50 moves up and down to adjust the size of the gap between the disc 48 and the bottom of the regulating cylinder 1, thereby adjusting the size of the output flow of the raw material particles from the regulating cylinder 1; S4: Finally, the mixed raw material particles fall into the interior of the collecting barrel 66 and are output from the interior of the discharging box 45. At the same time, when a part of the raw materials are mixed and output, the pull rope 43 is pulled to cause the trapezoidal block 42 to squeeze the latch 40, causing the rebound spring 65 to pull the conical plate 31 back to the interior of the mixing barrel 27 for the next use.

[0037] Compared with the prior art, the present invention adopts the above-mentioned homogeneous mixing process: the present invention ensures the uniform distribution of raw materials during the mixing process through the combination of the propeller 29-type mixing component and the conical plate 31 design, avoiding the uneven mixing phenomenon that may exist in the traditional mixing method, which helps to ensure the consistency of the composition of each batch of cable materials, thereby improving the consistency and stability of product quality. At the same time, in the traditional mixing process, the raw materials accumulate in the dead corners or inner walls of the mixing barrel 27, resulting in cleaning difficulties and waste of raw materials. The present solution effectively avoids raw material residues through the rebound design of the conical plate 31 and the scraping function of the cleaning barrel 30, reduces waste in the production process, and optimizes the utilization rate of raw materials.
