Description

Technical Field

[0001] This utility model belongs to the technical field of stirring devices, and specifically relates to an auxiliary stirring device for the production and processing of high molecular cross-linked low smoke halogen-free cable materials. Background Technology

[0002] Polymer cross-linked low-smoke halogen-free cable material is a new type of cable material obtained by combining polymer cross-linking technology with low-smoke halogen-free cable material. This material not only has the environmental protection characteristics of low-smoke halogen-free cable material, but also improves the material's physical properties such as heat resistance, creep resistance, and stress cracking resistance through polymer cross-linking technology. A stirring device is required to form polymer cross-linked low-smoke halogen-free cable material.

[0003] For example, Chinese patent CN212283675U discloses a device for uniformly mixing cable material, including a mixing tank, a mixing shaft, a motor, connecting rods, and a first scraper. The mixing tank has a discharge gate at the bottom of its wall. A mixing shaft coaxial with the mixing tank is installed inside the mixing tank. The mixing shaft passes through the bottom wall of the mixing tank and is connected to the motor located at the bottom of the mixing tank. A mixing paddle is provided on the mixing shaft. Several connecting rods are fixed at the top of the mixing shaft. The first scraper is fixed at the end of the connecting rods and is in close contact with the wall of the mixing tank.

[0004] The aforementioned patent addresses the problem that some raw materials tend to adhere to the side wall of the mixing tank during mixing in existing mixing devices, which is detrimental to the uniform mixing of raw materials. However, some defects still exist and need to be improved. The current mixing device's feed inlet design is relatively basic and lacks an effective mechanism to pre-disperse the incoming raw materials. It is difficult to ensure that the raw materials reach a relatively uniform state when entering the mixing device, resulting in the difficulty of efficiently and uniformly mixing raw material particles of different sizes during the mixing process. This not only prolongs the mixing time and increases energy consumption, but also affects the final quality of the product and production efficiency. Utility Model Content

[0005] In view of the problems mentioned in the background art, the purpose of this utility model is to provide an auxiliary stirring device for the production and processing of polymer cross-linked low-smoke halogen-free cable materials, so as to solve the problems mentioned in the background art.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] An auxiliary mixing device for the production and processing of cross-linked low-smoke halogen-free cable materials includes a mixing tank. A first driving assembly is located at the top of the mixing tank. A stirring rod is rotatably connected to the inside of the mixing tank via the first driving assembly. Stirring blades are fixedly connected to both sides of the stirring rod. A spiral blade is fixedly connected to the side of the stirring rod away from the stirring blades. A feed pipe is fixedly connected to one side of the mixing tank. A second driving assembly is located on one side of the feed pipe.

A first drive gear is fixedly connected to the output end of the first motor, and a first driven gear is meshed with one side of the first drive gear. The first driven gear is fixedly connected to the stirring rod.

[0010] As a preferred technical solution, the second drive assembly includes a second motor, which is fixedly connected to one side of the feed pipe. The output end of the second motor is fixedly connected to a first transmission rod. The side of the feed pipe away from the first transmission rod is rotatably connected to a second transmission rod. The crushing blades are respectively fixedly connected to the first transmission rod and the second transmission rod. A second drive gear is fixedly connected to one side of the first transmission rod, and a second driven gear is fixedly connected to one side of the second transmission rod. The second drive gear and the second driven gear are meshed together.

[0011] As a preferred technical solution, the transmission assembly includes a cam plate, which is fixedly connected to the second transmission rod. An arc-shaped block is movably connected to one side of the cam plate, and a connecting block is fixedly connected to the side of the arc-shaped block away from the cam plate.

A baffle plate is fixedly connected to the side of the connecting block away from the arc-shaped block, and one side of the baffle plate slides into the side of the sliding groove.

[0012] As a preferred technical solution, guide rods are fixedly connected to both sides of the bottom end of the barrier net, and the guide rods are located inside the spring. One side of the guide rod is slidably connected to the support plate.

[0013] As a preferred technical solution, a discharge pipe is fixedly connected to the bottom of the mixing tank, and a control valve is provided on one side of the discharge pipe.

[0014] In summary, the present invention has the following main advantages:

[0015] First, in this utility model, by installing a second drive assembly on the feed pipe, the crushing blades are driven to rotate by the second drive assembly, which can crush the incoming raw materials. The crushed raw materials fall into the mixing tank through the baffle. The raw materials can be homogenized to a certain extent before entering the mixing device, which will greatly promote the mixing efficiency in the subsequent mixing process. Raw material particles of different sizes can be more quickly and evenly distributed, thereby shortening the mixing time and improving the production efficiency of cable raw materials.

[0016] Secondly, in this utility model, the second driving component drives the transmission component to work, so that the transmission component drives the baffle to move. Multiple springs are installed under the baffle, and the springs are connected to the support plate, so that the baffle can vibrate inside the mixing tank. This allows the raw materials that have not passed through the baffle to rise and be crushed by the crushing blades. It can also prevent the baffle from blocking and affecting the normal falling of the raw materials, thereby facilitating the subsequent mixing of the cable raw materials. Attached Figure Description

A feed pipe 6 is fixedly connected to one side of the mixing tank 1. A second drive assembly 8 is provided on one side of the feed pipe 6. A crushing blade 7 is rotatably connected inside the feed pipe 6 through the second drive assembly 8. A transmission assembly 9 is provided on one side of the feed pipe 6. A support plate 12 is fixedly connected inside the feed pipe 6 below the crushing blade 7. Springs 11 are fixedly connected to both sides of the top of the support plate 12. A baffle 10 is fixedly connected to the top of the springs 11. The baffle 10 is located below the crushing blade 7.

[0024] refer to Figure 4 A scraper 31 is fixedly connected to one side of the stirring blade 3, and one side of the scraper 31 is in close contact with the inner wall of the mixing tank 1. By setting the scraper 31, the inner wall of the mixing tank 1 can be scraped to avoid the raw materials from adhering to the inner wall of the mixing tank 1, which would cause waste of raw materials and insufficient mixing.

[0025] refer to Figure 4 The first drive assembly 5 includes a first motor 51, which is fixedly connected to the top of the mixing tank 1. A first drive gear 52 is fixedly connected to the output end of the first motor 51. A first driven gear 53 is meshed with one side of the first drive gear 52. The first driven gear 53 is fixedly connected to the stirring rod 2. By setting the first drive assembly 5, the first motor 51 drives the first drive gear 52 to rotate, the first drive gear 52 drives the first driven gear 53 to rotate, and the first driven gear 53 drives the stirring rod 2 to rotate, thus providing power for the rotation of the stirring rod 2.

[0026] refer to Figure 1-2The second drive assembly 8 includes a second motor 81, which is fixedly connected to one side of the feed pipe 6. A first transmission rod 82 is fixedly connected to the output end of the second motor 81. A second transmission rod 85 is rotatably connected to the side of the feed pipe 6 away from the first transmission rod 82. The crushing blades 7 are respectively fixedly connected to the first transmission rod 82 and the second transmission rod 85. A second drive gear 83 is fixedly connected to one side of the first transmission rod 82, and a second driven gear 84 is fixedly connected to one side of the second transmission rod 85. The second drive gear 83 and the second driven gear 84 are meshed together. By setting up the second drive assembly 8, the second motor 81 drives the first transmission rod 82 to rotate, the first transmission rod 82 drives the second drive gear 83 to rotate, the second drive gear 83 drives the second driven gear 84 to rotate, and the second driven gear 84 drives the second transmission rod 85 to rotate, thereby driving the crushing blades to rotate and crush the incoming electrical raw materials.

[0027] refer to Figure 1-2 The transmission assembly 9 includes a cam plate 91, which is fixedly connected to the second transmission rod 85. An arc-shaped block 92 is movably connected to one side of the cam plate 91. A connecting block 93 is fixedly connected to the side of the arc-shaped block 92 away from the cam plate 91.

One side of the baffle plate 94 slides into the inside of one side of the chute 95. By setting the transmission component 9, when the second drive component 8 is working, the second drive rod drives the cam plate 91 to rotate. One side of the cam plate 91 intermittently contacts the arc block 92, pushing the arc block 92 to move, causing the arc block 92 to drive the connecting block 93 to move, and the connecting block 93 to drive the baffle 10 to move, so that the raw material on the baffle 10 can move. The baffle plate 94 slides in the chute 95 to play a certain role in blocking the material and prevent the material from falling out.

[0028] refer to Figure 3 Guide rods 13 are fixedly connected to both sides of the bottom end of the baffle 10, and the guide rods 13 are located inside the spring 11. One side of the guide rod 13 is slidably connected to the support plate 12. By setting the guide rods 13, the vibration position of the baffle 10 can be suppressed when the spring 11 vibrates, avoiding deviation and facilitating the reset of the baffle 10.

[0029] refer to Figure 1 The bottom end of the mixing tank 1 is fixedly connected to a discharge pipe 14, and a control valve 15 is provided on one side of the discharge pipe 14. The discharge pipe 14 is used to discharge the material inside the mixing tank 1, and the control valve 15 can open or close the discharge pipe 14.

[0030] Operating principle and advantages: Cable raw materials enter through the opening of the feed pipe 6. The second motor 81 drives the first transmission rod 82 to rotate, which in turn drives the second drive gear 83 to rotate. The second drive gear 83 drives the second driven gear 84 to rotate, which in turn drives the second transmission rod 85 to rotate. This drives the crushing blades to rotate and crush the incoming cable raw materials. The crushed materials fall through the baffle 10, while the uncrushed materials remain on the baffle 10. The second transmission rod 85 drives the two cam plates 91 to rotate. One side of the cam plate 91 intermittently contacts the arc-shaped block 92, pushing the arc-shaped block 92 to move, causing the arc-shaped block 92 to drive the connecting block 93. The moving connecting block 93 drives the baffle 10 to move. The spring 11 connected to the lower part of the baffle 10 vibrates on the support plate 12, thereby causing the baffle 10 to vibrate. The raw material that does not pass through the baffle 10 is then crushed upward by the crushing blades. This also prevents the baffle 10 from blocking and affecting the normal falling of the raw material, thus facilitating the subsequent mixing of the cable raw material. After the raw material enters the mixing tank 1, the first motor 51 drives the first drive gear 52 to rotate. The first drive gear 52 drives the first driven gear 53 to rotate. The first driven gear 53 drives the stirring rod 2 to rotate. The stirring rod 2 drives the stirring blade 3 and the scraper 31 to rotate, which can accelerate the mixing of the cable raw material inside the mixing tank 1.
