Description

Technical Field

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

[0002] The main purpose of rubber compounding is to improve the physical and mechanical properties of rubber products, improve processing and molding processes, and reduce production costs. By adding various compounding agents, such as fillers, reinforcing agents, accelerators, vulcanizing agents, antioxidants, and scorching inhibitors, to raw rubber or plastic rubber, the performance of rubber products can be significantly improved.

[0003] As disclosed in publication number "CN217729285U", a rubber mixing tank includes a mixing drum. The mixing drum has a central shaft inside its cavity, and spiral blades arranged in an S-shape around the central shaft. A servo motor is mounted on the top of the central shaft, and a sedimentation tank in a funnel shape is located at the bottom of the mixing drum. The sedimentation tank at the bottom of the mixing drum further settles impurities in the rubber, ensuring the quality of the refined rubber. Pressing the pressing shaft allows a rubber suction cup to slide up and down through a circular hole in the inner cavity of the pressurizing device. The buffer spring provides cushioning, making pressing easier and allowing control over the rubber discharge speed and increasing the equipment's production efficiency. Because the spiral blades are S-shaped, and the mixing drum has a heating and preheating effect, it effectively melts the rubber and improves agitation, resulting in higher-quality refined rubber.

[0004] The inventors believe that the above-mentioned rubber mixing tank can be used for mixing operations in rubber processing. Therefore, the rubber mixing tank is a mixing device for rubber processing. However, when the rubber mixing tank is discharging material, because the rubber material has strong adhesion after melting, some material will stick to the inside of the mixing tank and sedimentation tank, which will prevent these materials from being discharged and utilized normally, thus resulting in a waste of resources.

[0005] Therefore, this utility model provides a mixing device for rubber processing to solve the above problems. Utility Model Content

[0008] To facilitate the movement of the mixing device, as a preferred embodiment of the mixing device for rubber processing according to this utility model, the moving mechanism includes: a movable groove, a movable block, a pulley, a sliding plate, a chute, a mounting plate, and an electric push rod. The bottom surface of the support column has a movable groove, the inner surface of the movable groove is connected to the movable block, the bottom surface of the movable block is connected to the pulley, and one side surface of the top of the movable block is connected to the sliding plate. One end of the sliding plate passes through the chute opened on one end surface of the support column, the inner surface of the support column is connected to the mounting plate, and the top surface of the mounting plate is connected to the electric push rod. The movable end of the electric push rod passes through the mounting plate and connects to the top surface of the sliding plate.

[0009] In order to achieve normal operation control of the motor and drive the rotating shaft to rotate, as a preferred embodiment of the mixing device for rubber processing according to this utility model, the motor and the electric push rod are electrically connected to an external power source through a control switch, and the output end of the motor is fixedly connected to the rotating shaft.

[0010] In order to facilitate the assembly and disassembly of the first scraper, in a preferred embodiment of the mixing device for rubber processing according to this utility model, the positioning block is slidably connected to the connecting rod through the positioning groove, and the first bolt is threadedly connected to the first fixing hole through the connecting rod.

[0023] Please see Figures 1-4 This utility model provides the following technical solution: a mixing device for rubber processing, including a mixing barrel 1, a barrel lid 2 screwed onto the top surface of the mixing barrel 1, and a sedimentation tank 3 provided at the bottom end of the mixing barrel 1.

Connecting rods 10 are connected to the outer surfaces of both ends of the rotating shaft 7. A positioning groove 11 is opened on one side surface of the connecting rod 10, and the inner side of the positioning groove 11... A positioning block 12 is connected to the surface of the connecting rod 10. A first bolt 13 is connected through one end of the surface of the connecting rod 10. One end of the first bolt 13 extends into a first fixing hole 14 opened on one end of the surface of the positioning block 12. A connecting plate 15 is connected to one side of the surface of the positioning block 12. A first scraper 16 is connected to one side of the surface of the connecting plate 15. A slot 17 is opened on the bottom surface of the rotating shaft 7. An insert block 18 is connected to the inner surface of the slot 17. A second bolt 19 is connected through one end of the surface of the rotating shaft 7. One end of the second bolt 19 extends into a second fixing hole 20 opened on one end of the surface of the insert block 18. A rotating rod 21 is connected to the bottom surface of the insert block 18. A second scraper 22 is connected to the outer surface of the rotating rod 21. A moving mechanism is also provided on the bottom surface of the support column 5.

[0024] Preferably, the moving mechanism includes: a movable groove 23, a movable block 24, a pulley 25, a sliding plate 26, a slide groove 27, a mounting plate 28, and an electric push rod 29. The bottom surface of the support column 5 is provided with a movable groove 23. The inner surface of the movable groove 23 is connected to the movable block 24. The bottom surface of the movable block 24 is connected to the pulley 25. The top surface of the movable block 24 is connected to one side of the top surface of the movable block 24. One end of the sliding plate 26 passes through the slide groove 27 opened on one end surface of the support column 5. The inner surface of the support column 5 is connected to the mounting plate 28. The top surface of the mounting plate 28 is connected to the electric push rod 29. The movable end of the electric push rod 29 passes through the mounting plate 28 and is connected to the top surface of the sliding plate 26.

[0025] In practical use, the electric push rod 29 is activated, causing the movable end of the electric push rod 29 to drive the sliding plate 26 to slide in the slide groove 27. This allows the sliding plate 26 to drive the movable block 24 to move in the movable groove 23, causing the movable block 24 to move the pulley 25 out of the movable groove 23. The pulley 25 then contacts the ground and supports the equipment. At this point, the mixing device can be easily moved using the pulley 25. When the mixing device is moved to the designated position, the pulley 25 can be controlled to move upward again, causing the pulley 25 to retract into the movable groove 23. This allows the support column 5 to contact the ground again and support the equipment, ensuring the stability of the mixing device during use.

[0026] Preferably, the motor 6 and the electric push rod 29 are electrically connected to an external power source via a control switch, and the output end of the motor 6 is fixedly connected to the rotating shaft 7.

[0027] In practical use, the motor 6 and the electric push rod 29 can be controlled by a switch. The output end of the motor 6 can drive the rotating shaft 7 to rotate in the sealed bearing 8.

[0028] Preferably, the positioning block 12 is slidably connected to the connecting rod 10 through the positioning groove 11, and the first bolt 13 is threadedly connected to the first fixing hole 14 through the connecting rod 10.

[0029] In practical use, the positioning block 12 is slidably placed into the positioning groove 11, and then the first bolt 13 is screwed through the connecting rod 10 into the first fixing hole 14, so that the position of the positioning block 12 is fixed in the positioning groove 11, and the connecting plate 15 on one side of the first scraper 16 is connected to the connecting rod 10.

[0030] Preferably, the insert 18 is slidably connected to the rotating shaft 7 via the slot 17, and the second bolt 19 is threadedly connected to the second fixing hole 20 via the rotating shaft 7.

[0031] In practical use, slide the insert 18 into the slot 17, and then use the second bolt 19 to pass through the rotating shaft 7 and screw it into the second fixing hole 20. This will fix the insert 18 in the slot 17 and connect the rotating rod 21 to the rotating shaft 7.

[0032] Preferably, the movable block 24 is slidably connected to the support column 5 through the movable groove 23, and the sliding plate 26 is slidably connected to the support column 5 through the sliding groove 27.

[0033] In actual use, when the sliding plate 26 slides in the sliding groove 27, it will drive the movable block 24 to slide in the movable groove 23.

[0034] Working principle: When using this rubber processing mixing device, the operator feeds the rubber material into the mixing drum 1 through the feed inlet. The output of the motor 6 drives the spiral blades 9 at the bottom of the rotating shaft 7 to rotate. Because the mixing drum 1 has a heating and preheating effect, it effectively melts the rubber. Therefore, the spiral blades 9 can stir the material in the mixing drum 1, allowing the rubber material to be mixed. After the rubber material in the mixing drum 1 and settling tank 3 is discharged, some rubber material will adhere to the inner walls of the mixing drum 1 and settling tank 3. At this time, the motor 6 is started again, and the output of the motor 6 drives the rotating shaft 7 to rotate within the sealed bearing 8. The rotating shaft 7 then drives the first scraper 16 and the second scraper 22 through the connecting rod 10 and the rotating rod 21. The rotation of the first scraper 16 and the second scraper 22 allows the rubber material adhering to the inner walls of the mixing drum 1 and the settling tank 3 to be scraped off, so that the material can slide down to the bottom of the mixing device and be discharged normally through the discharge pipe, thereby reducing resource waste. Secondly, when the mixing device needs to be moved, the electric push rod 29 is activated, and the movable end of the electric push rod 29 drives the sliding plate 26 to slide in the slide groove 27. The sliding plate 26 then drives the movable block 24 to move in the movable groove 23, so that the movable block 24 moves the pulley 25 out of the movable groove 23, so that the pulley 25 contacts the ground and supports the equipment. At this time, the mixing device can be easily moved by the pulley 25, avoiding the need for operators to manually move the mixing device, thus bringing convenience to the movement of the mixing device.

[0035] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the 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.
