Abstract

This utility model discloses a heating device for a kneading machine, which includes an L-shaped fixed base. A mixing hopper is fixedly connected to the outer surface of the L-shaped fixed base, and a motor is fixedly connected to the right surface of the L-shaped fixed base. A first rotating shaft is fixedly connected to the output end of the motor, and a first stirring blade is fixedly connected to the outer surface of the first rotating shaft. By setting up a circulating pump, a water inlet pipe, a spiral tube, a thermostat, and an electric heating tube, the interior of the mixing hopper can be heated as needed, thereby improving practicality.

Description

Technical Field

[0001] This utility model relates to the field of kneading machine technology, and in particular to a kneading machine heating device. Background Technology

[0002] Kneaders, as key equipment for mixing and kneading materials in industrial production, are widely used in industries such as carbon, rubber, and plastics. They use stirring components to forcibly mix powders, granules, and binders to form uniform aggregates. Heating devices, as an important component of kneaders, must provide a stable heat source to promote material softening, reaction, or shaping.

[0003] However, existing kneading machine heating devices still have certain defects. For example, the heat source of traditional kneading machine heating devices is usually located in a fixed position, which will cause the temperature of the area near the heat source to be higher and the temperature of the area far from the heat source to be lower, which can easily cause local overheating or insufficient softening of the material. Utility Model Content

[0004] The purpose of this invention is to provide a heating device for a kneading machine, which can heat the interior of the mixing hopper as needed, thereby improving its practicality. It can also drive the first and second stirring blades to stir the water in the water storage chamber, thereby breaking up the temperature stratification of the water and making the hot water flow evenly in the spiral tube. This ensures that the heat transferred to the mixing hopper is evenly distributed, thus avoiding the occurrence of material mass deviation due to temperature fluctuations. Furthermore, the rotation of the first and second stirring blades and the first and second stirring paddles only needs to be driven by a single motor, thereby reducing equipment costs and further improving practicality.

[0005] To achieve the above objectives, a heating device for a kneading machine is provided, comprising: An L-shaped mounting base has a mixing hopper fixedly connected to its outer surface. A motor is fixedly connected to the right surface of the L-shaped mounting base. A first rotating shaft is fixedly connected to the output end of the motor. A first stirring paddle, a first gear, and a first stirring blade are fixedly connected to the outer surface of the first rotating shaft. A second rotating shaft is rotatably connected to the inner surface of the mixing hopper. A second stirring paddle, a second gear, and a second stirring blade are fixedly connected to the outer surface of the second rotating shaft. A circulation pump is fixedly connected to the outer surface of the mixing hopper. A water inlet pipe is fixedly connected to the input end of the circulation pump. A spiral tube is fixedly connected to the output end of the circulation pump. A thermostat is fixedly connected to the right surface of the L-shaped mounting base. An electric heating element is fixedly connected to the inner surface of the L-shaped mounting base. A water storage chamber is provided inside the L-shaped mounting base. A water injection pipe is provided on the upper surface of the water storage chamber. A pipe cap is threaded onto the outer surface of the water injection pipe.

[0006] According to the heating device of the kneader, the outer surface of the first rotating shaft is rotatably connected to the L-shaped fixed seat, and the outer surface of the first rotating shaft is rotatably connected to the mixing hopper.

[0007] According to the heating device of the kneader, the first gear meshes with the second gear.

[0008] According to the heating device of the mixing machine, the outer surface of the second rotating shaft is rotatably connected to the L-shaped fixed seat.

[0009] According to the heating device of the kneader, the end of the water inlet pipe away from the circulating pump extends into the interior of the water storage chamber, and the end of the spiral tube away from the water inlet pipe extends into the interior of the water storage chamber.

[0010] According to the heating device of the kneader, the outer surface of the spiral tube is in contact with the mixing hopper.

[0011] According to the heating device of the kneading machine, the temperature controller is electrically connected to the electric heating tube.

[0012] According to the heating device of the kneading machine, the motor, circulating pump, temperature controller, and electric heating tube are all electrically connected to an external power source.

[0013] The above-mentioned solution has the following beneficial effects: By incorporating a circulating pump, inlet pipe, spiral tube, thermostat, and electric heating element, the interior of the mixing hopper can be heated as needed, thus enhancing its practicality. Furthermore, the inclusion of a motor, first rotating shaft, first gear, second rotating shaft, and second gear allows the first and second stirring blades to agitate the water in the storage chamber, breaking down temperature stratification and ensuring uniform heat distribution within the spiral tube. This prevents material quality deviations caused by temperature fluctuations. Moreover, the rotation of the first and second stirring blades, as well as the first and second stirring paddles, requires only a single motor drive, reducing equipment costs and further enhancing practicality.

[0014] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0018] Reference Figure 1-4The heating device for a kneading machine according to this utility model embodiment includes: an L-shaped fixed base 1, a mixing hopper 2 fixedly connected to the outer surface of the L-shaped fixed base 1, a motor 3 fixedly connected to the right surface of the L-shaped fixed base 1, a first rotating shaft 4 fixedly connected to the output end of the motor 3, a first stirring paddle 5 fixedly connected to the outer surface of the first rotating shaft 4, a first gear 6 fixedly connected to the outer surface of the first rotating shaft 4, and a first stirring blade 7 fixedly connected to the outer surface of the first rotating shaft 4; a second rotating shaft 8 rotatably connected to the inner surface of the mixing hopper 2, a second stirring paddle 9 fixedly connected to the outer surface of the second rotating shaft 8, a second gear 10 fixedly connected to the outer surface of the second rotating shaft 8, and a second stirring blade 11 fixedly connected to the outer surface of the second rotating shaft 8; a circulation pump 12 fixedly connected to the outer surface of the mixing hopper 2, a water inlet pipe 13 fixedly connected to the input end of the circulation pump 12, and a spiral tube 14 fixedly connected to the output end of the circulation pump 12; and a temperature controller 15 fixedly connected to the right surface of the L-shaped fixed base 1. The temperature controller 15 is a mature existing technology component and will not be described in detail. An electric heating tube 16 is fixedly connected to the inner surface of the L-shaped fixed base 1. A water storage chamber 17 is provided inside the L-shaped fixed base 1. A water injection pipe 18 is provided on the upper surface of the water storage chamber 17. A pipe cap 19 is threaded onto the outer surface of the water injection pipe 18. The outer surface of the first rotating shaft 4 is rotatably connected to the L-shaped fixed base 1 and to the mixing hopper 2. The first gear 6 meshes with the second gear 10. The outer surface of the second rotating shaft 8 is rotatably connected to the L-shaped fixed base 1. The water inlet pipe 13 is located away from the circulating pump 12. The end of the spiral tube 14 extends into the water storage chamber 17, and the end of the spiral tube 14 away from the water inlet pipe 13 extends into the water storage chamber 17 to facilitate the flow of water. The outer surface of the spiral tube 14 is in contact with the mixing hopper 2 to facilitate the heating of the material inside the mixing hopper 2. The thermostat 15 is electrically connected to the electric heating tube 16 to control the temperature of the electric heating tube 6. The control circuits of the two are well known in the field, so they will not be described in detail. The motor 3, the circulating pump 12, the thermostat 15, and the electric heating tube 16 are all electrically connected to an external power source.

[0019] Working principle: During operation, the material is poured into the mixing hopper 2, and then the motor 3 is started. The first rotating shaft 4, under the meshing action of the first gear 6 and the second gear 10, drives the first stirring paddle 5 and the second stirring paddle 9 to rotate in opposite directions through the second rotating shaft 8, thus mixing the material. If necessary, the pipe cap 19 can be loosened and removed, and water can be poured into the water storage chamber 17 through the water injection pipe 18 for storage. Subsequently, the electric heating element 16 is controlled by the thermostat 15 to heat the water. Finally, the circulation pump 12 is started, and the hot water inside the water storage chamber 17 is absorbed through the water inlet pipe 13 and then sent into the spiral tube 14. Finally, the water flows back to the water storage chamber 17 and is heated again by the electric heating element 16. When hot water passes through the spiral tube 14, it heats the material in the mixing hopper 2, thus achieving simultaneous heating and stirring. Simultaneously, the rotation of the first rotating shaft 4 and the second rotating shaft 8 drives the first stirring blade 7 and the second stirring blade 11 to rotate in opposite directions, ensuring uniform flow of hot water within the spiral tube 14 and consistent heat distribution within the mixing hopper 2. This prevents material quality deviations caused by temperature fluctuations. Furthermore, the rotation of the first stirring blade 7, the second stirring blade 11, and the first stirring paddle 5 and the second stirring paddle 9 only requires a single drive unit, the motor 3, reducing equipment costs and further enhancing practicality.

[0020] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
