Description

Technical Field

[0001] The utility model relates to the technical field of stirring and mixing, and specifically, to a production device for low-smoke and halogen-free high-voltage cable materials. Background Art

[0002] Various raw materials such as polyethylene resin, flame retardant, antioxidant, etc. are rapidly mixed to make them evenly dispersed. During the mixing process, through the high-speed rotating stirring paddle and the specific mixing chamber structure, it is ensured that the materials reach a uniform mixing state in a short time, with advantages such as high mixing efficiency and good mixing uniformity. Different mixing times and speeds can be set to meet different formula requirements. The stirring blades or stirring rods in the existing mixing devices can only rotate in one direction, resulting in insufficient stirring of the materials, low stirring efficiency, and affecting the production efficiency. At the same time, there are large particle substances in the materials, and it is necessary to screen out the large particle substances from the materials. Therefore, a production device for low-smoke and halogen-free high-voltage cable materials is proposed. Summary of the Utility Model

The first helical gear drives the second helical gear and the third helical gear to rotate towards each other. At the same time, the rotating housing and the rotating shaft rotate towards each other.

[0006] As a further improvement of the technical solution, one end of the extrusion spring is fixedly connected to one side of the feed hopper, and the other end of the extrusion spring is fixedly connected to one side of the first extrusion block. The extrusion spring is used to drive the sliding rod to slide on the feed hopper.

[0010] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0011] In the low-smoke and halogen-free high-voltage cable material production equipment, the first helical gear in the stirring assembly drives the second helical gear and the third helical gear to rotate towards each other. At the same time, the rotating shell and the rotating shaft rotate towards each other, and the two first stirring plates on the outer side of the rotating shell and the two second stirring plates on the outer side of the rotating shaft rotate towards each other, so that the first stirring plates and the second stirring plates are staggered, thereby achieving the effect of rapid stirring. At the same time, the second extrusion block on the outer side of the rotating shell squeezes the first extrusion block, and then the first extrusion block drives the sliding rod and the filter plate to move in the feed hopper.

[0020] Embodiment 1

[0021] Please refer to Figures 1-4As shown in the figure, this embodiment provides a production device for low-smoke and halogen-free high-voltage cable materials, including a housing 1. A discharge pipe 2 is fixedly installed on the bottom side of the housing 1 and is in communication with the inside of the housing 1. A valve 3 is fixedly installed on the outside of the discharge pipe 2. The valve 3 is used to control the discharge of the materials in the housing 1, facilitating the staff to discharge the materials in the housing 1. A stirring assembly 4 is arranged in the housing 1. Through the stirring assembly 4, the materials can be fully stirred together, which is convenient for cable production. The stirring assembly 4 includes a rotating shell 41. The rotating shell 41 is rotatably installed on the top side of the housing 1 and penetrates the housing 1. Two first stirring plates 42 are fixedly installed on the outside of the rotating shell 41 and the first stirring plates 42 are located inside the housing 1. Through the rotating shell 41, the two first stirring plates 42 can be driven to rotate in the housing 1. The outer sides of the two first stirring plates 42 are in contact with the inner wall of the housing 1. The first stirring plates 42 scrape off the materials remaining on the inner wall of the housing 1, so as to achieve a cleaning effect. A rotating shaft 43 is rotatably installed in the rotating shell 41. Two second stirring plates 44 are fixedly installed on the outside of the rotating shaft 43 and are located inside the housing 1. Through the rotating shaft 43, the two second stirring plates 44 can be driven to rotate in the housing 1. A driving motor 45 is fixedly installed on the top side of the housing 1. The output shaft of the driving motor 45 is fixedly connected to a first helical gear 46. A second helical gear 47 is fixedly connected to the outside of the rotating shell 41 and is located outside the housing 1. A third helical gear 48 is fixedly connected to the outside of the rotating shaft 43 near the top end. The first helical gear 46 meshes with both the second helical gear 47 and the third helical gear 48. The first helical gear 46 drives the second helical gear 47 and the third helical gear 48 to rotate towards each other. At the same time, the rotating shell 41 and the rotating shaft 43 rotate towards each other, so that the first stirring plates 42 and the second stirring plates 44 are staggered, thus achieving a rapid stirring effect.

[0022] The top side of the housing 1 is provided with a feeding assembly 5. Through the feeding assembly 5, large particle substances in the material can be screened, and the yield rate of the produced cables can be increased. The feeding assembly 5 includes a feeding hopper 51. The feeding hopper 51 is fixedly installed on the top side of the housing 1 and is communicated with the inside of the housing 1. A filter plate 52 is slidably installed in the feeding hopper 51. A sliding rod 53 is fixedly installed at the middle position on one side of the filter plate 52 and slides on the feeding hopper 51. One end of the sliding rod 53 is fixedly connected with a first extrusion block 54. The sliding rod 53 is used to connect the filter plate 52 and the first extrusion block 54. By driving the filter plate 52 to move in the feeding hopper 51 by the sliding rod 53, an extrusion spring 55 is sleeved outside the sliding rod 53. A second extrusion block 56 is fixedly installed outside the rotating shell 41. One end of the extrusion spring 55 is fixedly connected to one side of the feeding hopper 51, and the other end of the extrusion spring 55 is fixedly connected to one side of the first extrusion block 54. The extrusion spring 55 is used to drive the sliding rod 53 to slide on the feeding hopper 51. Through the cooperation of the extrusion spring 55 and the first extrusion block 54, the filter plate 52 can reciprocate in the feeding hopper 51, so as to achieve the effect of screening the material. Under the cooperation of the second extrusion block 56 outside the rotating shell 41 and the first extrusion block 54, when the rotating shell 41 rotates clockwise, the second extrusion block 56 extrudes the first extrusion block 54, so that the first extrusion block 54 drives the filter plate 52 on the sliding rod 53 to vibrate in the feeding hopper 51. The second extrusion block 56 outside the rotating shell 41 extrudes the first extrusion block 54, and the first extrusion block 54 drives the sliding rod 53 and the filter plate 52 to move in the feeding hopper 51. At the same time, through the action of the extrusion spring 55, the filter plate 52 reciprocates in the feeding hopper 51, so as to achieve the effect of screening out large particle substances in the material.

[0023] When the low-smoke and halogen-free high-voltage cable material production equipment of this embodiment is specifically used, first, the power is turned on and the material is injected from the feeding hopper 51. The first helical gear 46 on the driving motor 45 drives the second helical gear 47 and the third helical gear 48 to rotate towards each other. At the same time, the rotating shell 41 and the rotating shaft 43 rotate towards each other, and the two first stirring plates 42 outside the rotating shell 41 and the two second stirring plates 44 outside the rotating shaft 43 rotate towards each other, so that the first stirring plate 42 and the second stirring plate 44 are staggered, so as to achieve the effect of rapid stirring. Then, the second extrusion block 56 outside the rotating shell 41 extrudes the first extrusion block 54, and the first extrusion block 54 drives the sliding rod 53 and the filter plate 52 to move in the feeding hopper 51. At the same time, through the action of the extrusion spring 55, the filter plate 52 reciprocates in the feeding hopper 51, so as to achieve the effect of screening out large particle substances in the material. Finally, the stirred material in the housing 1 is discharged from the discharge pipe 2.
