Description

Technical Field

[0001] This utility model relates to the field of mixing device technology, and in particular to a mixing device for flame-retardant cable materials. Background Technology

[0002] A flame-retardant cable material mixing device is a specialized device for preparing flame-retardant cable sheath or insulation materials. Its core function is to fully blend the base resin (such as PVC, PE), flame retardant (such as aluminum hydroxide, nitrogen and phosphorus compounds), smoke suppressant, filler and other additives in a specific ratio through an efficient and uniform mixing process, so as to ensure that the material has uniform flame retardancy, heat resistance and mechanical properties.

[0003] Regarding the above and existing related technologies, the inventors believe that the following defects often exist: when mixing raw materials, most of the time a separate stirring device is used for mixing. However, the mixing efficiency of a separate stirring device is poor, and it is impossible to quickly and evenly mix the raw materials, resulting in uneven dispersion of flame retardant, which affects the flame retardant performance of the finished cable. Utility Model Content

[0004] The technical problem to be solved by this utility model is that the existing flame retardant cable material mixing device cannot quickly and evenly mix the raw materials, resulting in poor mixing efficiency. Therefore, we propose a flame retardant cable material mixing device.

[0005] To achieve the above objectives, this application adopts the following technical solution: a flame-retardant cable material mixing device, comprising a bracket, a drive motor fixedly connected to one side of the bracket, a drive rod fixedly connected to the output end of the drive motor, a placement frame fixedly connected to one end of the drive rod, limit rods fixedly connected to both sides of the inner cavity of the placement frame, a sliding plate slidably connected to the surface of the limit rod, a tension spring sleeved on the bottom of the surface of the limit rod, a mixing box fixedly connected to one side of the sliding plate, a rotating rod rotatably connected to the bottom of the inner cavity of the placement frame, a gear fixedly connected to one side of the rotating rod, a toothed plate fixedly connected to the bottom of one side of the bracket, the top of the gear meshing with the bottom of the toothed plate, and a cam fixedly connected to the other side of the rotating rod.

[0006] Preferably, the bracket has limit grooves on both sides of its inner wall, and the placement frame has support rods fixedly connected to both sides. One end of each support rod is fixedly connected to a limit plate, and both the support rod and the limit plate are slidably connected inside the limit groove.

[0007] Preferably, a sliding groove is provided on one side of the bracket, and the rotating rod is slidably connected inside the sliding groove.

[0008] Preferably, the top of the mixing chamber is connected to a feed pipe, and the bottom of one side of the mixing chamber is connected to a discharge pipe.

[0009] Preferably, the top of the placement frame has a through groove, and the feed pipe is slidably connected inside the through groove.

[0010] Preferably, the two ends of the tension spring are fixedly connected to the bottom of the slide plate and the bottom of the inner cavity of the placement frame, respectively, and the tension spring is used to assist in the resetting of the mixing box.

[0011] Preferably, a damper is fixedly connected to the bottom of the inner cavity of the support, and the damper is used to reduce the impact of vibration on the mixing box.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] In this invention, the operation of the drive motor enables the drive rod to drive the support to swing, thereby mixing the raw materials inside the mixing box. With the addition of the support rod, limiting plate, and limiting groove, the weight of the placement frame and mixing box can be distributed to the drive motor, reducing the burden on the drive motor. Furthermore, the swing range of the support can be precisely limited to ensure a stable mixing process.

[0014] In this invention, the gears and toothed discs are designed to make the mixing box vibrate vertically while moving horizontally back and forth, thereby enhancing the convection diffusion and shear mixing of the powder raw materials. Furthermore, the use of cams in different directions can prevent synchronous movement when the mixing box swings, ensuring the normal operation of the mixing process. Attached Figure Description

[0020] The present invention will now be described in further detail with reference to the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0021] Reference Figure 1 As shown, this utility model provides a technical solution: a flame-retardant cable material mixing device, including a bracket 1, characterized in that: a drive motor 2 is fixedly connected to one side of the bracket 1, a drive rod 3 is fixedly connected to the output end of the drive motor 2, a placement frame 4 is fixedly connected to one end of the drive rod 3, limit rods 5 are fixedly connected to both sides of the inner cavity of the placement frame 4, a sliding plate 6 is slidably connected to the surface of the limit rod 5, a tension spring 7 is sleeved on the bottom of the surface of the limit rod 5, a mixing box 8 is fixedly connected to one side of the sliding plate 6, a rotating rod 9 is rotatably connected to the bottom of the inner cavity of the placement frame 4, a gear 10 is fixedly connected to one side of the rotating rod 9, a toothed plate 11 is fixedly connected to the bottom of one side of the bracket 1, the top of the gear 10 meshes with the bottom of the toothed plate 11, and the rotating rod 9... A cam 12 is fixedly connected to the other side. The user starts the drive motor 2 through an external controller. The drive motor 2 drives the placement frame 4 to swing through the drive rod 3. The placement frame 4 drives the mixing box 8 to swing through the limit rod 5, thereby mixing the raw materials. At the same time, when the placement frame 4 swings, it also drives the rotating rod 9 to swing. The rotating rod 9 drives the gear 10 to swing. Since the gear 10 and the toothed plate 11 are meshed with each other, the gear 10 will move along the bottom surface of the toothed plate 11 while swinging, thereby causing the gear 10 to rotate. The rotation of the gear 10 can drive the rotating rod 9 to rotate. The rotating rod 9 can then drive the mixing box 8 to vibrate vertically through the cam 12.

[0022] Reference Figure 1 As shown in this embodiment: Limiting grooves 13 are provided on both sides of the inner wall of the bracket 1, and support rods 14 are fixedly connected to both sides of the placement frame 4. One end of the support rod 14 is fixedly connected to a limiting plate 15. The support rod 14 and the limiting plate 15 are slidably connected inside the limiting grooves 13. The support rod 14 and the limiting plate 15 are fixed to both sides of the placement frame 4, and the support rod 14 and the limiting plate 15 can distribute the weight of the drive motor 2 from the placement frame 4 and the mixing box 8 through the limiting grooves 13.

[0023] Reference Figure 1 As shown in this embodiment: a sliding groove is provided on one side of the bracket 1, and the rotating rod 9 is slidably connected inside the sliding groove. The sliding groove is arc-shaped, which can provide space for the rotating rod 9 to swing during the swinging and mixing process, ensuring that it can smoothly swing back and forth and vibrate vertically during the mixing process.

[0024] Reference Figure 1As shown in this embodiment: the top of the mixing tank 8 is connected to the feed pipe 16, and the bottom of one side of the mixing tank 8 is connected to the discharge pipe 17. The feed pipe 16 and the discharge pipe 17 can be used for feeding and discharging.

[0025] Reference Figure 1 As shown in this embodiment: a through groove is provided at the top of the placement frame 4, and the feed pipe 16 is slidably connected inside the through groove. The through groove can provide space for the feed pipe 16 to move vertically, ensuring that the subsequent vibration mixing can operate normally.

[0026] Reference Figure 1 As shown in this embodiment: the two ends of the tension spring 7 are fixedly connected to the bottom of the slide plate 6 and the bottom of the inner cavity of the placement frame 4, respectively. The tension spring 7 is used to assist the mixing box 8 in resetting. The elastic return function of the tension spring 7 can reduce the shaking of the mixing box 8 after swinging, so that it returns to the initial position more accurately and improves the stability of the mixing process.

[0027] Reference Figure 1 As shown in this embodiment: a damper 18 is fixedly connected to the bottom of the inner cavity of the bracket 1. The damper 18 is used to reduce the impact of vibration on the mixing box 8. The damper 18 can reduce the impact of vibration on the mixing box 8 when the mixing box 8 is reset.

[0028] Working principle: The user starts the drive motor 2 through the external controller. The drive motor 2 drives the drive rod 3 to rotate, and the drive rod 3 drives the placement frame 4 to swing. The placement frame 4 drives the mixing box 8 to swing through the limit rod 5 and the slide plate 6, thereby achieving the purpose of mixing materials. At the same time, when the placement frame 4 swings, it also drives the rotating rod 9 to swing, and the rotating rod 9 drives the gear 10 to swing. Since the gear 10 and the toothed plate 11 are meshed with each other, the gear 10 will move along the bottom of the toothed plate 11 while swinging, so that the gear 10 will complete its rotation. Then the gear 10 will drive the rotating rod 9 to rotate, and the rotating rod 9 will drive the cam 12 to rotate. When the cam 12 contacts the bottom of the mixing box 8, the mixing box 8 will move upward, and the mixing box 8 will move through the slide plate 6 pulling the tension spring 7. When the cam 12 separates from the mixing box 8, the tension spring 7 will reset the mixing box 8 through its own elasticity. With the setting of the damper 18, the vibration generated during the reset of the mixing box 8 can be effectively suppressed, reducing the impact of the impact force on the mixing box 8, thereby achieving the purpose of increasing the mixing efficiency.

[0029] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
