Description

Technical Field

[0001] This utility model relates to the field of kneading machine technology, specifically an enhanced kneading machine for color masterbatch production. Background Technology

[0002] The reinforced kneader for color masterbatch production is a device specifically designed for the efficient mixing of pigments and plastic base materials. Through a powerful shearing, stirring, and heating system, pigments or additives are uniformly dispersed in plastic resin to form color masterbatches with consistent color and stable performance. This equipment features uniform mixing, precise temperature control, and automated operation, and is widely used in the color masterbatch preparation process in industries such as plastic products, coatings, and rubber.

[0003] When the kneader first starts working, the materials are not fully mixed and the interaction between particles is strong, especially for powders or high-viscosity materials that are not fully wetted, which exhibit high cohesion and rigidity. Therefore, the shear force is usually high in the initial stage. At this time, the materials are subjected to strong stretching, tearing and friction in the kneader, and the shear stress is large, which is conducive to breaking up particle agglomeration and promoting dispersion. As the kneading time increases, the materials gradually hydrate, soften and mix evenly. The friction and cohesion between particles decrease, the shear force will gradually decrease, and the fluidity of the materials will increase. The shear stress in the system tends to stabilize, and the mixing process enters the uniform dispersion stage.

[0004] Existing technology adjusts the shearing force according to the type of material and controls it through a frequency converter. Although the frequency converter controls the shearing force of the kneader with the advantages of flexible adjustment and strong adaptability, the motor output torque will drop significantly when the frequency converter is running at low frequency. This may result in insufficient power for the kneader when starting up or processing high-viscosity materials, affecting the shearing effect and mixing uniformity. Therefore, in order to address the above problems, an enhanced kneader for color masterbatch production is proposed. Utility Model Content

A drive assembly 4 and a transmission assembly 5 are fixedly connected to the upper end of the base plate 1. The drive assembly 4 includes a first support platform 41. The right side of the first support platform 41 is fixedly connected to the housing of a servo motor 42. A screw 43 is fixedly connected to the end of the main shaft of the servo motor 42. A guide column 44 is fixedly connected to the upper end of the first support platform 41. A movable frame plate 45 is spirally connected to the outside of the screw 43. The upper end of the movable frame plate 45 is fixedly connected to the housing of a stepper motor 46. A second gear 47 is fixedly connected to the end of the main shaft of the stepper motor 46. The transmission assembly 5 includes a second support platform 51. A vertical plate 52 is fixedly connected to the top of the second support platform 51. The inner side of the vertical plate 52 is rotatably connected to a transmission column 54 through a ball bearing 53. A second pulley 55 and a third gear 57 are fixedly connected to the outside of the transmission column 54. A transmission belt 56 is sleeved on the outside of the second pulley 55.

[0030] As a further implementation of this solution, the top of the base plate 1 is fixedly connected to the kneader 2, the first support platform 41 and the second support platform 51. The drive component 4 is located at the front end of the transmission component 5, and the transmission component 5 is located at the front end of the kneader 2. Through the above arrangement, this layout makes the overall structure of the device more compact and the coordination between the components stronger, providing a stable structural foundation for achieving efficient kneading, while facilitating the installation and maintenance of the equipment.

[0031] As a further implementation of this solution, the kneading assembly 3 includes a shaft 31, with a kneading blade 32, a first gear 33, and a first pulley 34 fixedly connected to the outside of the shaft 31. The shaft 31 is rotatably connected to the baffle plate 35 via a bearing. The shaft 31 extends into the interior of the kneader 2 and is rotatably connected to the kneader 2. The rear end of the baffle plate 35 is fixedly connected to the kneader 2. A transmission belt 56 is sleeved on the outside of the first pulley 34, and the first pulley 34 is rotatably connected to the second pulley 55 via the transmission belt 56. Through the above arrangement, power can be transmitted efficiently to realize the kneading operation of materials. The use of bearings reduces the friction during rotation, improves transmission efficiency and equipment service life, and ensures the stability and reliability of the kneading process.

[0032] As a further implementation of this solution, the inner side of the movable frame plate 45 is provided with threaded holes and straight holes. The inner side of the movable frame plate 45 is slidably connected to the guide column 44. The rear end of the movable frame plate 45 is provided with a through hole. The main shaft of the stepper motor 46 is rotatably connected to the movable frame plate 45 through bearings. Through the above settings, the torque can be adjusted. By moving the position of the movable frame plate 45, the third gear 57 of different diameters can be selected, thereby changing the magnitude of the torque after linkage. This flexible torque adjustment mechanism enables the device to adapt to different types of materials and enhances the adaptability of the equipment under different material processing conditions.

[0033] As a further implementation of this solution, the transmission column 54 is embedded inside the vertical plate 52. There are multiple transmission columns 54 and multiple third gears 57. The bottom ends of the multiple third gears 57 are flush with each other. The outer sides of the multiple transmission columns 54 are equipped with second pulleys 55 and transmission belts 56. Through the above settings, the device can flexibly adjust the torque as needed to achieve efficient kneading of different materials.

[0034] Workflow: When kneading the masterbatch material, the stepper motor 46 controls the speed via an existing frequency converter, thus controlling the shearing force on the material inside the kneader 2. To control the kneading torque based on the material type, the servo motor 42 is activated, driving the screw 43 to rotate. The screw 43 then moves the helically connected movable frame plate 45, which slides on the outside of the guide column 44. The movable frame plate 45 drives the stepper motor 46 and the second gear 47 to move. There are multiple third gears 57, each with a different diameter. The larger the diameter of the third gear 57, the greater the torque on the shaft column 31 after linkage. When the second gear 47 moves to the lower end of the designated third gear 57, the stepper motor 46 is activated, driving the second gear 47 to rotate. The second gear 47 then drives the corresponding third gear 57 to rotate. After the third gear 57 rotates, it drives the transmission column 54 and the second pulley 55 to rotate. The transmission column 54 rotates inside the vertical plate 52 through the corresponding ball bearing 53, which can reduce the friction when the transmission column 54 rotates. The transmission belt 56 rotates and drives the shaft column 31, the kneading blade 32 and the first gear 33 to rotate through the corresponding first pulley 34. Through the two shaft columns 31, the kneading blade 32 and the first gear 33, the kneading effect of the material inside the kneader 2 is achieved. During this period, although other transmission columns 54 will rotate, it will not affect the kneading of the material inside the kneader 2. Based on the above principles, the device can change the torque when kneading the material according to the type of material to be kneaded. This can ensure the convenience of kneading high-viscosity materials, ensure that the shearing effect and mixing uniformity are not affected, and improve the practical flexibility of the device.

[0035] 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, the scope of which is defined by the appended claims and their equivalents.
