Abstract
Description
Technical Field
[0001] This utility model relates to the field of cable production equipment technology, and in particular to a high-efficiency stirring device for mixing halogen-free flame-retardant cable materials. Background Technology
[0002] Cable is a conductive wire used to transmit electrical energy or electrical signals. Halogen-free flame-retardant cable material refers to cable insulation and sheath materials that do not contain halogens and have flame-retardant properties. It is mainly used in applications requiring environmental protection, low toxicity, and low smoke.
[0003] In the production process of halogen-free flame-retardant cable materials, it is necessary to fully mix various raw materials to ensure the performance of the cable materials. The mixing device is the key equipment to achieve this mixing process. When the existing mixing device mixes the cable materials, the mixing paddle in the center usually mixes the materials inside the mixing drum. This mixing method results in the materials far away from the rotation range of the mixing paddle not being fully mixed, which easily creates mixing dead zones. At the same time, the existing mixing paddles mostly adopt a unidirectional mixing method, which makes the movement trajectory of the mixing paddle fixed, resulting in uneven mixing of materials and the problem of mixing dead zones.
[0004] Therefore, we provide a high-efficiency mixing device for mixing halogen-free flame-retardant cable materials. Utility Model Content

[0019] Example: A high-efficiency mixing device for mixing halogen-free flame-retardant cable materials, such as... Figures 1-4 As shown, the device includes a stirring drum 1, a stirring support cover 2 inserted into the upper end of the stirring drum 1, a motor 3 inserted into the upper end of the stirring support cover 2, a support connecting block 4 installed at the output end of the motor 3, a first gear 5 and a second gear 6 installed at the lower end of the support connecting block 4, a first fixed gear tooth 10 and a second fixed gear tooth 11 simultaneously provided on the outside of the first gear 5 and the second gear 6, a third fixed gear tooth 13 and a fourth fixed gear tooth 14 provided between the first gear 5 and the second gear 6, a rotating column 15 installed at the lower end of the first gear 5 and the second gear 6, and a plurality of stirring paddles 16 evenly installed on the outer surface of the rotating column 15.
[0020] The lower end of the stirring support cover 2 is provided with a connecting groove, the output end of the motor 3 is inserted through the connecting groove, the support connecting block 4 rotates inside the connecting groove, and the first gear 5 and the second gear 6 are symmetrically distributed.
[0021] The size, tooth size, and tooth spacing of the first gear 5 and the second gear 6 are the same. The teeth on the first gear 5 are located in the lower half of the outer surface of the first gear 5, and the teeth on the second gear 6 are located in the upper half of the outer surface of the second gear 6.
[0022] A support ring 9 is installed on the inner wall of the connecting groove. The first fixed gear tooth 10 and the second fixed gear tooth 11 are both fixedly installed on the inner side of the support ring 9. The first fixed gear tooth 10 and the second fixed gear tooth 11 are both semi-fan-shaped. The first fixed gear tooth 10 and the second fixed gear tooth 11 are symmetrically staggered. The first fixed gear tooth 10 is located in the upper half of the inner side of the support ring 9, and the second fixed gear tooth 11 is located in the lower half of the inner side of the support ring 9.
[0023] The support ring 9 has a fixed plate 12 inside, and a fixed column is installed at the lower end of the fixed plate 12. The fixed plate 12 is fixedly connected to the inner wall of the mixing cylinder 1 through the fixed column. The third fixed tooth 13 and the fourth fixed wheel tooth 14 are both fixedly installed on the outer surface of the fixed plate 12.
[0024] Both the third fixed tooth 13 and the fourth fixed tooth 14 are arranged in a semi-fan shape. The third fixed tooth 13 and the fourth fixed tooth 14 are symmetrically staggered. The third fixed tooth 13 is located on the upper half of the outer surface of the fixed disk 12, and the fourth fixed tooth 14 is located on the lower half of the outer surface of the fixed disk 12. The first gear 5 and the second gear 6 are both movable between the support ring 9 and the fixed disk 12. The first gear 5 is meshed with the second fixed tooth 11 and the fourth fixed tooth 14, and the second gear 6 is meshed with the first fixed tooth 10 and the third fixed tooth 13.
[0025] All components inside the mixing drum 1 are made of high-strength alloy steel. When the cable material is being mixed, the motor 3 is activated, which drives the support connecting block 4 to rotate. During the rotation of the support connecting block 4, the first gear 5 and the second gear 6 below it revolve. Connected by the rotating column 15, the first gear 5 and the second gear 6 respectively drive the stirring paddle 16 to revolve along the inner wall of the mixing drum 1. During the revolve of the first gear 5 and the second gear 6, since the gears are symmetrically distributed, when the first gear 5 meshes with the second fixed gear 11, the second gear 6 meshes with the first fixed gear 10. During the movement of the first gear 5 and the second gear 6, the first gear 5 and the second gear 6 rotate. The cable material located below the first fixed gear 10 and the second fixed gear 11 is stirred in the forward direction by the rotation of the stirring paddle 16. When the first gear 5 disengages from the second fixed gear 11, the first gear 5 meshes with the fourth fixed gear 14. At this time, the first gear 5 and the second gear 6... It is a reverse rotation motion. Based on the consistent area below the first fixed gear 10 and the fourth fixed gear 14, the second fixed gear 11 and the third fixed gear 13, the cable material inside the mixing drum 1 is stirred in the forward direction and then stirred in the reverse direction by the stirring paddle 16. The stirring paddle 16 repeats the above operation until the cable material inside the mixing drum 1 is fully mixed. Driven by the motor 3, the stirring paddle 16 can make a circular revolution inside the mixing drum 1. Relative to the central position, it can further reduce the stirring dead angle and improve the fullness of the mixing of the cable material. With the meshing of the first gear 5 with the second fixed gear 11 and the fourth fixed gear 14, and the meshing of the second gear 6 with the first fixed gear 10 and the third fixed gear 13, the stirring paddle 16 can rotate in both directions during the revolution, which can fully mix the material inside the mixing drum 1. With the revolution and forward and reverse rotation of the stirring paddle 16, the material inside the mixing drum 1 can be stirred in all directions and at multiple angles, avoiding the occurrence of stirring dead angles and improving the uniformity of material mixing.
[0026] like Figures 1-4As shown, a limiting groove 18 is formed on the upper surface of the mixing drum 1, and a limiting block 19 is inserted into the limiting groove 18. The limiting block 19 is fixedly connected to the outer surface of the mixing support cover 2. A limiting ring 17 is installed on the inner wall of the upper half of the mixing drum 1, and the upper end of the limiting ring 17 is tightly fitted to the lower end of the mixing support cover 2.
[0027] When the impeller 16 is installed inside the mixing drum 1, the limiting block 19 on the mixing support cover 2 is aligned with the limiting groove 18 on the mixing drum 1 and inserted until the lower end of the mixing support cover 2 is in contact with the limiting ring 17, thus completing the installation and positioning of the impeller 16. Under the action of the limiting ring 17, the limiting block 19 and the limiting groove 18, firstly, the installation of the impeller 16 can be positioned to ensure the accuracy of the position between the first fixed gear 10 and the third fixed gear 13, and between the second fixed gear 11 and the fourth fixed gear 14, thus ensuring the stability of the impeller 16 during operation. Secondly, the position of the mixing support cover 2 can be limited to prevent the mixing support cover 2 from rotating during the operation of the impeller 16, further ensuring the stability of the impeller 16 during operation.
[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
