Description

Technical Field

[0001] The utility model relates to the field of masterbatch processing, in particular to a stirring device for masterbatch. Background Art

[0002] In today's highly competitive manufacturing landscape, masterbatch production requires not only precise color matching but also product stability and consistent quality. Traditional mixing devices are often limited by inefficient mixing methods and uneven heating conditions, resulting in large fluctuations in the moisture content of finished masterbatch, seriously affecting the performance and aesthetics of the final product. Utility Model Content

[0003] In view of this, the utility model provides a stirring device for masterbatch. The design highlight lies in the hot air channel arranged in the shaft seat. The warm air generated by the hot air blower enters through the inlet of the hot air channel, passes through the entire shaft seat, and is finally released from the outlet of the stirring chamber, in close contact with the masterbatch, completely avoiding the inconsistency of water evaporation, thereby improving the moisture content of the finished masterbatch.

[0004] The purpose of the utility model is achieved through the following technical solutions:

[0005] A stirring device for masterbatch includes a base, a shaft seat fixed to the base, an outer cavity portion that can rotate relative to the shaft seat and forms a stirring chamber with the shaft seat, and a driving unit that drives the outer cavity portion to rotate. The shaft seat is provided with a hot air channel, the inlet of the hot air channel is connected to a hot air blower, and the outlet is connected to the stirring chamber.

[0006] The highlight of the design lies in the hot air channel built into the shaft seat. The warm air generated by the hot air blower enters through the inlet of the hot air channel, passes through the entire shaft seat, and is finally released from the outlet of the mixing chamber, where it comes into close contact with the masterbatch. This innovative layout realizes the directional transmission of thermal energy, greatly promoting the uniform heating of the masterbatch during the mixing process, eliminating local overheating or cold spots that may be caused by traditional heating methods, and ensuring that each masterbatch enjoys consistent temperature treatment. The precise guidance of the hot air completely avoids the inconsistency of water evaporation, thereby achieving an unprecedented stability in the moisture content of the finished masterbatch. The dynamic rotation of the outer cavity combined with the assistance of hot air stimulates the activity of the masterbatch molecules, accelerates the mutual penetration between particles, and significantly improves the mixing rate and uniformity. Thanks to the perfect combination of heating and mixing, each masterbatch can grow under the same conditions, ensuring a high degree of consistency in the quality of masterbatch between batches, meeting the stringent requirements of the high-end application market.

[0007] Preferably, the axle seat is placed horizontally.

[0008] The layout of the transverse shaft seat helps to evenly distribute the material throughout the mixing chamber, avoiding material accumulation due to center of gravity offset, thereby promoting uniform heating and mixing of the masterbatch during the mixing process, ensuring the stability of the finished product quality.

[0009] Compared with vertical installation, the horizontally arranged shaft seat bears a more uniform radial load, effectively reducing the wear of transmission components, extending the service life of the equipment and reducing maintenance costs.

[0010] Preferably, a first annular groove is dug around the left and right sides of the shaft seat respectively, and a second annular groove is dug in the outer cavity to cooperate with the first annular groove. The first annular groove and the second annular groove together enclose a ball space, and a plurality of balls are arranged in the ball space.

[0011] A first annular groove is cut on the left and right sides of the shaft seat, while a second annular groove is designed in the corresponding position of the outer chamber. The two grooves fit together to form a closed ball bearing space, which is embedded with multiple balls. The presence of the balls greatly reduces the friction during the rotation of the outer chamber, ensuring smooth and efficient mixing operation, even when handling large quantities of materials. Due to the even distribution of the balls, the outer chamber can achieve smooth rotation in both high-speed and low-speed mixing scenarios, avoiding unnecessary vibration and noise, and creating a more comfortable working environment.

[0012] Preferably, the driving unit includes a motor and a roller driven by the motor, wherein the roller contacts the outer surface of the outer cavity and can drive the outer cavity to rotate relative to the shaft seat.

[0013] The rollers adhere closely to the outer surface of the outer chamber, transmitting power through direct contact, causing the outer chamber to rotate about the shaft seat. This direct coupling between the motor and rollers eliminates the need for additional drive chains or gear mechanisms, simplifying the power transmission path, reducing energy loss, and improving overall power conversion efficiency. The motor speed can be adjusted according to actual operating conditions. Combined with a sophisticated control system, the outer chamber's rotational speed can be precisely controlled, ensuring rapid response during startup, acceleration, and deceleration, meeting diverse mixing needs.

[0014] Preferably, the cross-sections of the first annular groove and the second annular groove are semicircular.

[0015] The semicircular cross-section of the first and second annular grooves maximizes the contact area between the balls and the groove walls, ensuring the balls remain stable during movement. This effectively prevents deviation from their trajectory even at high speeds, thus ensuring smooth operation of the mixing chamber. The semicircular grooves, in conjunction with the balls, act as a barrier, effectively isolating them from external impurities, preventing dust or fine particles from disrupting the proper operation of the ball bearing system. They also help maintain a clean and dry interior, promoting uniform mixing and heating of materials.

[0016] Preferably, the hot air channel includes a main air channel and a plurality of branch air channels connected to the main air channel. The inlet of the hot air channel is arranged at the end of the main air channel, and the outlet of the hot air channel is arranged at the end of the branch air channel.

[0017] The hot air channel is not only the core of the heating mechanism but also a key factor in determining the final product quality. Our multi-stage hot air channel design consists of a main air channel and multiple branch air channels connected vertically to it. The main air channel guides the hot air into the mixing chamber and distributes it evenly to every corner using vertically arranged branch air channels. This multi-stage diffusion pattern significantly enhances the heat energy coverage, ensuring temperature uniformity during the masterbatch heating process and avoiding local overheating or cold spots. The multi-stage hot air channel design allows for independent control of the airflow and temperature of each branch, making it possible to adapt to the characteristics and process requirements of different masterbatches and enabling operators to flexibly adjust parameters based on actual conditions to achieve the optimal heating effect.

[0018] Preferably, the plurality of branch air ducts are perpendicular to the main air duct.

[0019] The vertical connection between the branch air duct and the main air duct not only shortens the time for hot air to reach the mixing chamber, but also reduces heat energy loss and speeds up the heating speed of masterbatch, which has a direct positive impact on improving production efficiency and reducing costs.

[0020] Preferably, there are two hot air channels, and the two hot air channels are symmetrically arranged.

[0021] Symmetrically arranged dual hot air channels ensure comprehensive heat coverage within the mixing chamber, effectively avoiding localized overheating or insufficient heating that can occur with a single channel. This ensures consistent masterbatch temperature throughout the heating process, thereby improving product quality. The dual-channel layout increases the contact area between the hot air and the masterbatch, promoting rapid heat transfer and shortening heating time. This not only improves production efficiency but also contributes to energy conservation and carbon reduction, supporting sustainable development goals.

[0022] Preferably, a fixing seat is provided on the base, and the shaft seat is embedded in the fixing seat.

[0023] The embedded design strengthens the connection between the shaft seat and the base, effectively resisting vibration and impact even during high-speed mixing, ensuring the overall stability of the device and reducing potential safety risks. The stable shaft seat foundation further improves the accuracy and repeatability of the mixing process, which is crucial for masterbatch production, which requires strict control of process parameters and helps maintain a consistently high level of product quality.

[0024] Preferably, the inner surface of the outer cavity is provided with stirring ridges.

[0025] The addition of the stirring ridges creates a series of "obstacles" during the stirring process, forcing the masterbatch to tumble and collide repeatedly within the cavity. This significantly increases the frequency of contact between particles and promotes deeper fusion. The presence of the ridges not only stirs the masterbatch but also disrupts the flow of the hot air, allowing it to better penetrate the masterbatch layer, further enhancing the hot air's heating effect and ensuring that the masterbatch reaches the ideal temperature in a short period of time.

[0026] Compared with the prior art, the present invention has the following beneficial effects:

[0027] The highlight of the masterbatch mixing device of this invention lies in the hot air channel built into the shaft base. The warm air generated by the hot air blower enters through the hot air channel's inlet, traverses the entire shaft base, and is finally released from the outlet of the mixing chamber, where it comes into close contact with the masterbatch. This innovative layout achieves directional transmission of thermal energy, greatly promoting uniform heating of the masterbatch during the mixing process, eliminating local overheating or cold spots that may result from traditional heating methods, and ensuring that each batch of masterbatch receives consistent temperature treatment. The precise guidance of the hot air completely avoids inconsistencies in water evaporation, thereby achieving unprecedented stability in the moisture content of the finished masterbatch. The dynamic rotation of the outer cavity, combined with the assistance of hot air, stimulates the activity of the masterbatch molecules, accelerates the mutual penetration between particles, and significantly improves the mixing rate and uniformity. Thanks to the perfect combination of heating and mixing, each masterbatch grows under the same conditions, ensuring high consistency in masterbatch quality between batches and meeting the stringent requirements of the high-end application market.

[0034] The technical solution in this application will be described below with reference to the accompanying drawings.

[0035] This embodiment provides a stirring device for masterbatch, including a base 100, a shaft seat 200 fixed to the base 100, an outer cavity 400 that can rotate relative to the shaft seat 200 and form a stirring chamber 300 with the shaft seat 200, and a driving unit 500 that drives the outer cavity 400 to rotate. The shaft seat 200 is provided with a hot air channel 210, the inlet of the hot air channel 210 is connected to the hot air blower 430, and the outlet is connected to the stirring chamber 300.

[0036] A key design feature is the hot air channel 210 within the shaft base 200. Warm air generated by the hot air blower enters through the inlet of the hot air channel 210, traverses the entire shaft base 200, and is finally released through the outlet of the mixing chamber 300, where it comes into close contact with the masterbatch. This innovative layout achieves targeted heat transfer, significantly promoting uniform heating of the masterbatch during mixing. This eliminates localized overheating or cold spots that can occur with traditional heating methods, ensuring consistent temperature treatment for every batch of masterbatch. The precise guidance of the hot air completely eliminates uneven water evaporation, resulting in unprecedented moisture stability in the finished masterbatch. The dynamic rotation of the outer chamber 400, combined with the assistance of hot air, stimulates the activity of the masterbatch molecules, accelerates interpenetration between particles, and significantly improves mixing speed and uniformity. Thanks to the seamless integration of heating and mixing, each masterbatch is grown under identical conditions, ensuring highly consistent quality from batch to batch, meeting the stringent requirements of the high-end application market.

[0037] In this embodiment, the shaft seat 200 is placed horizontally.

[0038] The layout of the transverse shaft seat 200 helps to evenly distribute the material in the entire mixing chamber 300, avoiding material accumulation due to center of gravity shift, thereby promoting uniform heating and mixing of the masterbatch during the mixing process, and ensuring the stability of the finished product quality.

[0039] Compared with vertical installation, the horizontally arranged shaft seat 200 bears a more uniform radial load, effectively reducing the wear of transmission components, extending the service life of the equipment, and reducing maintenance costs.

[0040] In this embodiment, a first annular groove 220 is dug around the left and right sides of the shaft seat 200, and a second annular groove 410 is dug in the outer cavity 400 to cooperate with the first annular groove 220. The first annular groove 220 and the second annular groove 410 are jointly enclosed to form a ball space, and a plurality of balls are arranged in the ball space.

[0041] A first annular groove 220 is excavated on the left and right sides of the shaft seat 200, and a second annular groove 410 is designed at the corresponding position of the outer cavity 400. The two grooves fit together to form a closed ball space with multiple balls embedded inside. The presence of the balls greatly reduces the friction during the rotation of the outer cavity 400, ensuring the smoothness and efficiency of the stirring operation, even when handling large quantities of materials. Due to the uniform distribution of the balls, the outer cavity 400 can achieve smooth rotation in both high-speed and low-speed stirring scenarios, avoiding unnecessary vibration and noise, and creating a more comfortable working environment.

[0042] In this embodiment, the driving unit 500 includes a motor 510 and a roller 520 driven by the motor 510 . The roller 520 contacts the outer surface of the outer cavity 400 and can drive the outer cavity 400 to rotate relative to the shaft seat 200 .

[0043] Roller 520 is in close contact with the outer surface of outer chamber 400, transmitting power through direct contact, causing outer chamber 400 to rotate about shaft seat 200. The direct coupling between motor 510 and roller 520 eliminates the need for additional transmission chains or gear mechanisms, simplifies the power transmission path, reduces energy loss, and improves overall power conversion efficiency. Motor 510 can adjust its speed according to actual operating conditions. Combined with a sophisticated control system, it achieves precise control of the rotation speed of outer chamber 400, enabling rapid response during startup, acceleration, and deceleration to meet diverse stirring needs.

[0044] In this embodiment, the cross-sections of the first annular groove 220 and the second annular groove 410 are semicircular.

[0045] The semicircular cross-sections of first and second annular grooves 220 and 410 maximize the contact area between the balls and the groove walls, ensuring the balls remain stable during movement. This effectively prevents deviation from their trajectory even at high speeds, thereby ensuring smooth operation of mixing chamber 300. The semicircular grooves, in conjunction with the balls, act as a barrier, effectively isolating them from external impurities and preventing dust or fine particles from disrupting the proper operation of the ball bearing system. They also help maintain a clean and dry interior, facilitating uniform mixing and heating of materials.

[0046] In this embodiment, the hot air channel 210 includes a main air channel 211 and multiple branch air channels 212 connected to the main air channel 211. The inlet of the hot air channel 210 is located at the end of the main air channel 211, and the outlet of the hot air channel 210 is located at the end of the branch air channels 212. The outlet of the hot air channel 210 is provided with a blocking net 213.

[0047] The hot air channel 210 is not only the core of the heating mechanism but also a key factor in determining the final product quality. Our multi-stage hot air channel 210 design comprises a main air channel 211 and multiple branch air channels 212 connected vertically thereto. Hot air is guided into the mixing chamber 300 through the main air channel 211 and evenly distributed to every corner by means of the vertically arranged branch air channels 212. This multi-stage diffusion pattern significantly enhances the heat coverage, ensuring temperature uniformity during the masterbatch heating process and avoiding localized overheating or cold spots. The multi-stage hot air channel 210 design allows for independent control of the airflow and temperature of each branch, enabling adaptation to the characteristics and process requirements of different masterbatches. This allows operators to flexibly adjust parameters based on actual conditions to achieve the optimal heating effect.

[0048] In this embodiment, the plurality of branch air ducts 212 are perpendicular to the main air duct 211 .

[0049] The vertical connection between the branch air duct 212 and the main air duct 211 not only shortens the time for the hot air to reach the mixing chamber 300, but also reduces heat energy loss and speeds up the heating speed of the masterbatch, which has a direct positive impact on improving production efficiency and reducing costs.

[0050] In this embodiment, there are two hot air channels 210 , and the two hot air channels 210 are symmetrically arranged.

[0051] The symmetrical arrangement of dual hot air channels 210 ensures comprehensive heat coverage within the mixing chamber 300, effectively avoiding localized overheating or insufficient heating that can occur with a single channel. This ensures consistent temperature of the masterbatch throughout the heating process, thereby improving product quality. The dual-channel layout increases the contact area between the hot air and the masterbatch, promoting rapid heat transfer and shortening heating time. This not only improves production efficiency but also contributes to energy conservation and carbon reduction, supporting sustainable development goals.

[0052] In this embodiment, a fixing seat 110 is provided on the base 100 , and the shaft seat 200 is embedded in the fixing seat 110 .

[0053] The embedded design strengthens the connection between the shaft base 200 and the base 100, effectively resisting vibration and impact even during high-speed mixing, ensuring the overall stability of the device and reducing potential safety risks. The stable foundation of the shaft base 200 further improves the accuracy and repeatability of the mixing process, which is crucial for masterbatch production, which requires strict control of process parameters and helps maintain a consistently high level of product quality.

[0054] In this embodiment, stirring ridges 420 are provided on the inner surface of the outer cavity 400 .

[0055] The addition of the stirring ridges 420 creates a series of "obstacles" during the stirring process, forcing the masterbatch to tumble and collide repeatedly within the chamber. This significantly increases the frequency of contact between particles and promotes deeper fusion. The ridges not only agitate the masterbatch but also disrupt the flow of the hot air, allowing it to better penetrate the masterbatch layer, further enhancing the hot air's heating effect and ensuring that the masterbatch reaches the desired temperature in a short period of time.

[0056] Although the 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 variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
