Description

Technical Field

[0001] This utility model relates to the technical field of rubber mixing equipment, specifically a rapid rubber mixing device. Background Technology

[0002] A rubber mixing plant is a piece of equipment used in the rubber processing industry to mix raw rubber with various compounding agents and then plasticize it. It effectively improves production efficiency, shortens mixing time, ensures product quality, and helps reduce energy consumption and environmental pollution.

[0003] During rubber compounding, the rubber compounder repeatedly presses the rubber through the rollers of the mixing machine. According to the production process requirements, the compounding agent powder is added to the surface of the pressed rubber in sequence using a material tray. By rotating the rollers, the compounding agent powder is mixed and pressed with the rubber. Through repeated rolling, the rubber and compounding agents are mixed evenly to obtain a rubber product that meets the requirements for use.

[0004] However, when rubber compounders add compounding agent powder to the rubber during the rubber compounding process, they usually rely on experience to sprinkle the compounding agent powder onto the surface of the rubber on the rollers. This can easily lead to a large amount of compounding agent powder accumulating in one place, resulting in a large amount of compounding agent powder being mixed in a small area of ​​the rubber. It is necessary to repeatedly press the rubber with rollers for a long time in order to evenly mix these compounding agent powders into the rubber being compounded, thus delaying the rubber compounding process. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides a rapid rubber mixing device that improves the efficiency of mixing and refining rubber with compounding agent powders.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a rapid rubber mixing device, comprising a mixing mill and two rollers installed inside the mixing mill, a powder hopper connected between the inner walls of the two sides at the front end of the mixing mill, the powder hopper being inclinedly arranged above the adjacent rollers, the smaller end of the powder hopper facing the rollers, and a discharge component connected to the inner wall of the smaller end of the powder hopper.

[0007] Furthermore, the discharge assembly includes a discharge roller and a discharge motor. The discharge motor is embedded in the inner wall of the smaller end of the powder hopper. The output end of the discharge motor passes through the inner wall of the powder hopper and is fixedly connected to one end of the discharge roller. The other end of the powder hopper is rotatably connected to the inner wall of the other side of the powder hopper through a rotating shaft.

[0008] Furthermore, several brush bristles are fixedly connected to the outer wall of the discharge roller, and these brush bristles abut against the inner wall of the top of the powder hopper.

[0009] Furthermore, a scraper is fixedly connected to the inner wall of the smaller end of the powder hopper, and the scraper abuts against the brush bristles.

[0010] Furthermore, a vibrator is fixedly connected to the bottom center of the powder hopper.

[0011] Furthermore, a packing frame is fixedly connected to the larger end of the powder hopper, and connecting components are connected to both sides of the packing frame. Extension rods are fixedly connected to both sides of the front end of the mixer. T-shaped grooves are opened on the inner side of the two extension rods adjacent to the mixer. The two connecting components are respectively connected to the T-shaped grooves on both sides.

[0012] Furthermore, the connecting assembly includes a limiting block and a pulley. The limiting block is fixedly connected to the side wall of the packing frame, and the pulley is fixedly connected to the limiting block via a rotating shaft. The limiting block is slidably connected to the narrower end of the T-slot, and the pulley is located inside the wider end of the T-slot and slidably connected to the T-slot.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] This type of rapid rubber mixing device can more evenly add compounding agent powder from the powder hopper to the rubber on the lower roller through the discharge component. This makes the compounding agent powder and rubber mix more evenly under the pressure of the roller, avoiding the powder accumulation problem that may be caused by manually adding compounding agent powder, and making the uniform mixing of compounding agent powder and rubber faster and more efficient.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Please see Figures 1 to 5 A rapid rubber mixing device includes a mixer 1 and two rollers 2 installed inside the mixer 1. A powder hopper 3 is connected between the inner walls of the two sides at the front end of the mixer 1. The powder hopper 3 is inclined and arranged above the adjacent rollers 2. The smaller end of the powder hopper 3 faces the roller 2. A discharge component is connected to the inner wall of the smaller end of the powder hopper 3.

[0023] like Figures 1 to 5 As shown, the rubber rapid mixing device of this utility model is similar in structure to existing rubber mixing devices. The main improvement of this utility model is that it can mix compounding agent powder with rubber more quickly and evenly, thereby improving the rubber mixing efficiency. Figures 1 to 5 As shown, in the rubber rapid mixing device of this utility model, when in use, the rubber mixing worker can put the compounding agent powder that needs to be mixed and mixed into the powder hopper 3. During the mixing process, the compounding agent powder inside the powder hopper 3 can be added to the rubber on the roller 2 at a uniform speed through the internal discharge component, so that the compounding agent powder and the rubber can be initially and uniformly mixed, thereby improving the rubber mixing and mixing efficiency.

[0024] like Figure 3 and Figure 4 As shown, the discharge assembly includes a discharge roller 4 and a discharge motor 5. The discharge motor 5 is embedded in the inner wall of the smaller end of the powder hopper 3. The output end of the discharge motor 5 passes through the inner wall of the powder hopper 3 and is fixedly connected to one end of the discharge roller 4. The other end of the powder hopper 3 is rotatably connected to the inner wall of the other side of the powder hopper 3 via a rotating shaft. By starting the discharge motor 5, the discharge roller 4 is driven to rotate outward at the discharge port of the powder hopper 3, thereby causing the powder at the bottom of the discharge roller 4 to gradually move outward and fall onto the rubber on the lower roller 2, achieving a uniform feeding and mixing operation.

[0025] like Figures 3 to 5 As shown, several bristles 6 are fixedly connected to the outer wall of the discharge roller 4, and these bristles 6 abut against the inner wall of the top of the powder hopper 3. The bristles 6 on the outer side of the discharge roller 4 can better carry the compounding agent powder inside the powder hopper 3 out of the powder hopper 3, making the discharge of the compounding agent powder more stable. At the same time, the bristles 6 can fill the gap between the discharge roller 4 and the inner wall of the powder hopper 3, thus ensuring that the compounding agent powder inside the powder hopper 3 will not slip out of the powder hopper 3 when the discharge roller 4 is not rotating.

[0026] like Figures 3 to 5As shown, a scraper 7 is fixedly connected to the inner wall of the smaller end of the powder hopper 3, and the scraper 7 abuts against the brush bristles 6. When the discharge roller 4 rotates and carries the compounding agent powder inside the powder hopper 3 to the outside of the powder hopper 3 through the brush bristles 6, some of the compounding agent powder may adhere to the brush bristles 6. With the scraper 7, the powder adhering to the brush bristles 6 can be scraped off and fallen off when the discharge roller 4 rotates, thereby improving the discharge effect of the compounding agent powder.

[0027] like Figure 2 As shown, a vibrator 8 is fixedly connected to the bottom center of the powder hopper 3. When the compounding agent powder in the powder hopper 3 clumps or accumulates, the vibrator 8 can be activated to drive the powder hopper 3 to vibrate, thereby vibrating off the compounding agent powder adhering to the inner wall of the powder hopper 3, and then letting it fall onto the rubber on the roller 2 for mixing and rubber compounding.

[0028] like Figures 1 to 3 As shown, a packing frame 9 is fixedly connected to the larger end of the powder hopper 3. Connecting components are connected to both sides of the packing frame 9. Extension rods 12 are fixedly connected to both sides of the front end of the mixer 1. T-shaped grooves 101 are opened on the inner side of the two extension rods 12 adjacent to the mixer 1. Two connecting components are connected to the T-shaped grooves 101 on both sides respectively. Through the packing frame 9 and the connecting components on both sides, the powder hopper 3 can be moved from the T-shaped grooves 101 on both sides of the mixer 1 to the T-shaped grooves 101 of the extension rods 12, thus moving the powder hopper 3 slightly away from the roller 2. At this time, the rubber mixer can add the compounding agent powder from the packing frame 9 into the powder hopper 3. Because there is a distance between the powder hopper 3 and the roller 2, the rubber mixer's clothing will not be stirred into the roller 2, improving the safety of the compounding agent powder filling operation.

[0029] like Figures 1 to 5 As shown, the connecting assembly includes a limiting block 10 and a pulley 11. The limiting block 10 is fixedly connected to the side wall of the packing frame 9, and the pulley 11 is fixedly connected to the limiting block 10 via a rotating shaft. The limiting block 10 is slidably connected to the narrower end of the T-slot 101, and the pulley 11 is located inside the wider end of the T-slot 101 and slidably connected to it. The movement of the limiting block 10 within the T-slot 101 prevents the powder hopper 3 from swaying. Simultaneously, the rolling and sliding of the pulley 11 within the T-slot 101 facilitates smoother movement of the powder hopper 3 on the mixer 1.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention.
