Description

Technical Field

[0001] The utility model relates to the technical field of rubber accelerator stirring and mixing, in particular to a rubber accelerator stirring and mixing device. Background Art

[0002] The rubber vulcanization accelerator NS has a white or light yellow appearance and exists in the form of powder or granules. In the production process of existing synthetic rubber, a special accelerator NS needs to be added to the rubber material to accelerate the reaction rate between sulfur and rubber. To mix the accelerator NS and the rubber material, a stirring and mixing device is required.

[0003] A Chinese patent with the publication number CN217855585U discloses a raw material mixing and stirring device for rubber accelerators, including a mixing box. The upper end surface of the mixing box is communicated with a feeding box, the upper end surface of the feeding box is communicated with a feeding hopper, the bottom of the feeding hopper is communicated with a telescopic pipe, and the other end of the telescopic pipe is communicated with a material distribution box; a first motor is installed on the right side wall of the feeding box, and the output end of the first motor penetrates through the right side wall of the feeding box and is fixedly installed with a screw rod. Pour the raw materials of the rubber accelerator into the feeding hopper. By starting the first motor, the slider drives the material distribution box to move left or right, and then drives the feeding pipe to move left or right. During this process, the raw materials of the rubber accelerator are evenly sprinkled in the mixing box. By starting the second motor, when the stirring rod rotates, the raw materials of the rubber accelerator can be quickly mixed, effectively preventing material accumulation and achieving the effect of quickly mixing the raw materials of the rubber accelerator evenly.

[0004] During the mixing process of the existing stirring and mixing device for the rubber vulcanization accelerator NS and the rubber material, the rubber vulcanization accelerator NS is usually directly poured into the rubber material in its entirety. The rubber vulcanization accelerator NS is likely to accumulate in the rubber material and is prone to insufficient stirring, resulting in poor mixing uniformity. Therefore, a rubber accelerator stirring and mixing device is proposed for the above problems. Content of the Utility Model

[0005] In order to make up for the deficiencies of the existing technology and solve the problems existing in the existing technology, the utility model proposes a rubber accelerator stirring and mixing device.

[0006] The technical solution adopted by the present utility model to solve its technical problems is as follows: A stirring and mixing device for rubber accelerators of the present utility model includes a footrest, on which a tank body is installed. A control panel is installed on the side wall of the tank body. A first feed port is opened on the top plate of the tank body, and a feed hopper is installed at the first feed port on the top plate of the tank body. A rolling groove is opened on the inner wall of the feed hopper, and a rotating rod is rotatably installed on the inner wall of the feed hopper. A rotating wheel is fixedly sleeved on the rotating rod, and the rotating wheel is assembled in the rolling groove. A material guiding groove is opened on the rotating wheel. One end of the rotating rod is welded with a first gear. A first motor is installed on the top plate of the tank body through a machine base. A second gear is installed on the output shaft of the first motor, and the second gear meshes with the first gear. A feed pipe is installed on the top plate of the tank body. A second motor is installed on the top plate of the tank body through a machine base. A stirring rod is installed on the output shaft of the second motor, and a spiral blade and a stirring frame are installed on the stirring rod. By pouring rubber vulcanization accelerator NS into the feed hopper, the rubber vulcanization accelerator NS pours into the material guiding groove. Then the rotating wheel rotates, and the rotating wheel pours the rubber vulcanization accelerator NS in the material guiding groove into the tank body. Since the rubber vulcanization accelerator NS is poured into the rubber compound in small amounts and multiple times, the rubber vulcanization accelerator NS is dispersed and evenly distributed in the rubber compound, which is beneficial to improving the uniformity of the mixing of the rubber vulcanization accelerator NS and the rubber compound.

[0007] Preferably, a discharge hopper is installed at the bottom side of the tank body, a discharge pipe is installed on the discharge hopper, and a valve is installed on the discharge pipe. An annular groove is opened on the inner wall of the tank body. A pulse electromagnet is fixedly installed on the top side of the inner wall of the annular groove, and the pulse electromagnet is connected to the control panel through an internal circuit. A plurality of connecting grooves are opened on the inner wall of the annular groove, a connecting bar is assembled in the connecting groove, and an inner cylinder is installed on the connecting bar. The inner cylinder is slidably assembled in the annular groove. An iron sheet is fixedly installed on the inner cylinder, and the iron sheet is located below the pulse electromagnet. A plurality of springs are installed on the bottom side of the inner cylinder and the inner wall of the annular groove. By the instantaneous attraction of the magnetic force generated by the pulse electromagnet, the iron sheet drives the inner cylinder to move vertically upward. Then the magnetic force disappears, and the spring pulls the inner cylinder to move vertically downward. Since the switching frequency of the occurrence and disappearance of the magnetic field is extremely high, the inner cylinder generates high-frequency vibration. Under the action of the high-frequency vibration, the rubber compound on the inner wall of the inner cylinder falls downward, realizing the rapid discharging of the rubber compound, which is beneficial to improving the discharging efficiency.

[0008] The advantages of the present utility model are as follows:

[0009] 1. In this utility model, rubber vulcanization accelerator NS is poured into the feed hopper, and then into the material guiding groove. After that, the rotating wheel rotates, and the rotating wheel pours the rubber vulcanization accelerator NS in the material guiding groove into the tank body. Since the rubber vulcanization accelerator NS is poured into the rubber compound in small amounts and multiple times, the rubber vulcanization accelerator NS is dispersed and evenly distributed in the rubber compound, which is beneficial to improving the uniformity of the mixing of the rubber vulcanization accelerator NS and the rubber compound.

[0010] 2. In this utility model, when the pulsed electromagnet generates magnetic force, it instantaneously attracts the iron sheet to move towards the pulsed electromagnet. The iron sheet drives the inner cylinder to move vertically upward. Then, when the magnetic force disappears, the spring pulls the inner cylinder to move vertically downward. Since the switching frequency of the occurrence and disappearance of the magnetic field is extremely high, the inner cylinder generates high-frequency vibration. Under the action of the high-frequency vibration, the rubber compound on the inner wall of the inner cylinder falls downward, realizing the rapid feeding of the rubber compound, which is beneficial to improving the feeding efficiency.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts fall within the protection scope of the present utility model.

[0019] Please refer to Figures 1-4As shown in the figure, a stirring and mixing device for rubber accelerators includes a tripod 1, on which a tank body 2 is installed. A control panel 3 is installed on the side wall of the tank body 2. A first feed port 4 is opened on the top plate of the tank body 2. A feed hopper 5 is installed at the position of the first feed port 4 on the top plate of the tank body 2. A rolling groove 6 is opened on the inner wall of the feed hopper 5. A rotating rod 7 is rotatably installed on the inner wall of the feed hopper 5. A rotating wheel 8 is fixedly sleeved on the rotating rod 7. The rotating wheel 8 is assembled in the rolling groove 6. A material guiding groove 9 is opened on the rotating wheel 8. One end of the rotating rod 7 is welded with a first gear 10. A first motor 11 is installed on the top plate of the tank body 2 through a machine base. A second gear 12 is installed on the output shaft of the first motor 11. The second gear 12 meshes with the first gear 10. A feed pipe 13 is installed on the top plate of the tank body 2. A second motor 14 is installed on the top plate of the tank body 2 through a machine base. A stirring rod 15 is installed on the output shaft of the second motor 14. A spiral blade 16 and a stirring frame 17 are installed on the stirring rod 15; during operation, in the existing stirring and mixing device, when mixing rubber vulcanization accelerator NS and rubber materials, the rubber vulcanization accelerator NS is usually directly poured into the rubber materials completely. The rubber vulcanization accelerator NS is likely to accumulate in the rubber materials and is prone to insufficient stirring, resulting in poor mixing uniformity. By pouring sulfur and rubber into the tank body 2 from the feed pipe 13, through the operation of the second motor 14, the stirring rod 15 is driven to rotate. The stirring rod 15 drives the spiral blade 16 and the stirring frame 17 thereon to rotate. The spiral blade 16 and the stirring frame 17 stir sulfur and rubber, enabling the reaction between sulfur and rubber. Then, the rubber vulcanization accelerator NS is poured into the feed hopper 5. Through the operation of the first motor 11, the second gear 12 is driven to rotate. The second gear 12 drives the first gear 10 to rotate. The first gear 10 drives the rotating rod 7 to rotate. The rotating rod 7 drives the rotating wheel 8 to rotate. When the material guiding groove 9 of the rotating wheel 8 rotates to the upper side, the rubber vulcanization accelerator NS is poured into the material guiding groove 9. Then, the rotating wheel 8 rotates in the rolling groove 6, and the rotating wheel 8 pours the rubber vulcanization accelerator NS in the material guiding groove 9 into the tank body 2. The addition of the rubber vulcanization accelerator NS to the rubber compound can promote the activation of the vulcanizing agent, thereby accelerating the cross-linking reaction between the vulcanizing agent and rubber molecules and accelerating the reaction rate between sulfur and rubber. Each time the rotating wheel 8 rotates one circle, a volume of the rubber vulcanization accelerator NS equal to the volume of the material guiding groove 9 is added to the tank body 2. At the same time, the spiral blade 16 and the stirring frame 17 stir the rubber vulcanization accelerator NS and the rubber compound, enabling a volume of the rubber vulcanization accelerator NS equal to the volume of the material guiding groove 9 to be fully mixed with the rubber compound. By controlling the feeding amount and feeding speed of the rubber vulcanization accelerator NS, the rubber vulcanization accelerator NS is poured into the rubber compound in small amounts and multiple times, enabling the rubber vulcanization accelerator NS to be dispersed and evenly distributed in the rubber compound, avoiding excessive accumulation of the rubber vulcanization accelerator NS inside the rubber compound, which is beneficial to improving the mixing uniformity of the rubber vulcanization accelerator NS and the rubber compound.

[0020] Please refer to Figure 5As shown in the figure, a discharge hopper 18 is installed on the bottom side of the tank body 2. A discharge pipe 19 is installed on the discharge hopper 18, and a valve 20 is installed on the discharge pipe 19. An annular groove 21 is formed on the inner wall of the tank body 2. A pulse electromagnet 22 is fixedly installed on the top side of the inner wall of the annular groove 21. The pulse electromagnet 22 is connected to the control panel 3 through an internal circuit. A plurality of connecting grooves 23 are formed on the inner wall of the annular groove 21. A connecting bar 24 is assembled in the connecting groove 23. An inner cylinder 25 is installed on the connecting bar 24. The inner cylinder 25 is slidably assembled in the annular groove 21. An iron sheet 26 is fixedly installed on the inner cylinder 25. The iron sheet 26 is located below the pulse electromagnet 22. A plurality of springs 27 are installed on the bottom side of the inner cylinder 25 and the inner wall of the annular groove 21. During operation, after the existing stirring and mixing device finishes mixing the rubber vulcanization accelerator NS and the rubber compound, the rubber compound needs to be poured out. Since the rubber compound is easily attached to the inner wall of the device, the discharging efficiency of the rubber compound is relatively low. By opening the valve 20, the rubber compound is poured out from the discharge pipe 19. A sinusoidal current is passed through the pulse electromagnet 22 through a wire by the control panel 3, so that the pulse electromagnet 22 is magnetized. The sinusoidal current will switch between positive and negative half-cycles. Every time the sinusoidal current switches between positive and negative half-cycles, the current disappears. The switching frequency of the positive and negative half-cycles of the sinusoidal current is very high. Therefore, the magnetic field frequency generated by the pulse electromagnet 22 is also very high. The magnetic force generated by the pulse electromagnet 22 is also instantaneous. The iron sheet 26 is attracted by the magnetic force generated by the pulse electromagnet 22 to move towards the pulse electromagnet 22. The iron sheet 26 drives the inner cylinder 25 to move towards the pulse electromagnet 22, that is, the inner cylinder 25 moves vertically upward. Then the magnetic force disappears. Under the downward pulling force of the spring 27, the spring 27 pulls the inner cylinder 25 to move away from the pulse electromagnet 22, that is, the inner cylinder 25 moves vertically downward. Since the switching frequency of the generation and disappearance of the magnetic field is extremely high, the inner cylinder 25 generates high-frequency vibration. Under the action of the high-frequency vibration, the rubber compound on the inner wall of the inner cylinder 25 falls off downward, realizing the rapid discharging of the rubber compound, which is beneficial to improving the discharging efficiency.

[0021] Working principle: In the process of mixing rubber vulcanization accelerator NS with rubber materials by existing stirring and mixing devices, rubber vulcanization accelerator NS is usually directly poured entirely into the rubber materials. Rubber vulcanization accelerator NS is prone to accumulate in the rubber materials and is likely to cause insufficient stirring, resulting in poor mixing uniformity. By pouring sulfur and rubber into the tank body 2 from the feed pipe 13, through the operation of the second motor 14, the stirring rod 15 is driven to rotate. The stirring rod 15 drives the spiral blades 16 and the stirring frame 17 on it to rotate. The spiral blades 16 and the stirring frame 17 stir sulfur and rubber, enabling the reaction between sulfur and rubber. Then, rubber vulcanization accelerator NS is poured into the feed hopper 5. Through the operation of the first motor 11, the second gear 12 is driven to rotate. The second gear 12 pushes the first gear 10 to rotate. The first gear 10 drives the rotating rod 7 to rotate. The rotating rod 7 drives the rotating wheel 8 to rotate. When the material guiding groove 9 of the rotating wheel 8 rotates above, rubber vulcanization accelerator NS is poured into the material guiding groove 9. Then, the rotating wheel 8 rotates in the rolling groove 6, and the rotating wheel 8 pours the rubber vulcanization accelerator NS in the material guiding groove 9 into the tank body 2. Adding rubber vulcanization accelerator NS to the rubber compound can promote the activation of the vulcanizing agent, thereby accelerating the cross-linking reaction between the vulcanizing agent and rubber molecules and accelerating the reaction rate between sulfur and rubber. Each time the rotating wheel 8 rotates one circle, a volume of rubber vulcanization accelerator NS equal to the volume of the material guiding groove 9 is added to the tank body 2. At the same time, the spiral blades 16 and the stirring frame 17 stir the rubber vulcanization accelerator NS and the rubber compound, enabling a volume of rubber vulcanization accelerator NS equal to the volume of the material guiding groove 9 to be fully mixed with the rubber compound. By controlling the feeding amount and feeding speed of rubber vulcanization accelerator NS, rubber vulcanization accelerator NS is poured into the rubber compound in small amounts and multiple times, making rubber vulcanization accelerator NS disperse and evenly distribute in the rubber compound, avoiding excessive rubber vulcanization accelerator NS from accumulating inside the rubber compound, which is beneficial to improving the mixing uniformity of rubber vulcanization accelerator NS and the rubber compound;After the existing stirring and mixing device finishes mixing rubber vulcanization accelerator NS with the rubber compound, it is necessary to pour out the rubber compound. Since the rubber compound is easily attached to the inner wall of the device, the discharging efficiency of the rubber compound is relatively low. By opening the valve 20, the rubber compound is poured out from the discharging pipe 19. A sine current is passed through the wire into the pulsed electromagnet 22 through the control panel 3, causing the pulsed electromagnet 22 to be magnetized. The sine current will switch between positive and negative half-cycles. Every time the sine current switches between positive and negative half-cycles, the current disappears. The switching frequency of the positive and negative half-cycles of the sine current is very high. Therefore, the magnetic field frequency generated by the pulsed electromagnet 22 is also very high. The magnetic force generated by the pulsed electromagnet 22 is also instantaneous. The pulsed electromagnet 22 generates a magnetic force that instantaneously attracts the iron sheet 26 to move towards the pulsed electromagnet 22. The iron sheet 26 drives the inner cylinder 25 to move towards the pulsed electromagnet 22, that is, the inner cylinder 25 moves vertically upward. After that, the magnetic force disappears. Under the downward pulling force of the spring 27, the spring 27 pulls the inner cylinder 25 to move away from the pulsed electromagnet 22, that is, the inner cylinder 25 moves vertically downward. Since the switching frequency of the occurrence and disappearance of the magnetic field is extremely high, the inner cylinder 25 generates high-frequency vibration. Under the action of the high-frequency vibration, the rubber compound on the inner wall of the inner cylinder 25 falls off downward, realizing the rapid discharging of the rubber compound, which is beneficial to improving the discharging efficiency.
