Description

Technical Field

[0001] This utility model relates to mixing equipment, specifically a multi-cylinder dispersive mixing mechanism and mixing equipment with counterweight. Background Technology

[0002] Referring to the transmission structure of the multi-cylinder dispersion mixer disclosed in the utility model patent with announcement number CN218166889U, this solution relies on the main shaft for lifting and lowering, and the platform is rotated by the rotating mechanism on the main shaft, thereby adjusting the position of the mixer. A motor is also installed on the platform to drive the mixer to rotate. However, since the mixer needs to stir the medium in the container from a relatively far position, it will cause a difference in lever arm. At this time, the motors and mixers on both sides of the main shaft will have a mismatch in weight. During long-term use, the main shaft is prone to uneven force, which will affect its service life. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a multi-cylinder dispersion stirring mechanism and stirring equipment with counterweight, which can alleviate the technical problem of uneven force on both sides of the main shaft and the shortened service life of the main shaft with long-term use.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a multi-cylinder dispersing and stirring mechanism with counterweight, comprising a lifting main shaft, a transmission platform mounted on the lifting main shaft, a stirrer mounted on the transmission platform, and a driver mounted on the transmission platform. The stirrer and the driver are respectively located on both sides of the lifting main shaft. A first extension module is also provided on the transmission platform between the stirrer and the lifting main shaft. A second extension module is provided on the transmission platform at a position between the lifting main shaft and the driver or at a position corresponding to the driver. The weight of the first extension module is less than that of the second extension module, and the two work together to reduce the weight difference between the two sides of the lifting main shaft on the transmission platform. The first extension module and the second extension module form a functional cooperation.

[0005] As a further improvement of this utility model, the transmission platform includes a transmission belt for connecting the driver and the stirrer, and a housing that at least covers the upper and lower sides of the transmission platform; the first expansion module is installed on the upper or lower side of the housing corresponding to the transmission platform.

[0006] As a further improvement of this utility model, the transmission platform includes a transmission belt for connecting the driver and the stirrer, and a housing that at least covers both sides of the transmission platform; the first expansion module is mounted on the housing.

[0007] As a further improvement of this utility model, a connector is provided on the housing. The connector is located on the upper or lower side of the transmission belt and extends from the housing to the other side of the housing corresponding to the transmission belt, and is used to connect the first expansion module.

[0008] As a further improvement of this utility model, a top-opening mechanism is also provided in the transmission platform at the position between the first expansion module and the lifting main shaft and / or between the first expansion module and the stirrer. The top-opening mechanism is used to push the transmission belt open to both sides to increase the installation space of the first expansion module.

[0009] As a further improvement of this utility model, the transmission belt is a belt, and the stirrer and the driver are both connected to the belt through pulleys to form a transmission. The opening mechanism includes at least two pulleys, which are used to open the belt to the sides away from the belt.

[0010] As a further improvement of this utility model, the first expansion module includes one or more of the following: a metering component for metering feed, a feeding component for guiding feed, and a heating component for heating the feed medium; the second expansion module includes a drive module corresponding to the metering component for supplying power or controlling the metering component, and a drive module corresponding to the feeding component for opening and closing the feeding component.

[0011] The beneficial effects of this utility model are as follows: by setting a first expansion module between the stirrer and the lifting spindle on the transmission platform, and adding a second expansion module on the other side, the weight difference between the two sides of the lifting spindle on the transmission platform is reduced, thereby alleviating the problem of uneven force on the lifting spindle caused by weight difference in the prior art. On the one hand, it can avoid deformation and wear caused by the lifting spindle being under unbalanced force for a long time, significantly extending the service life of the lifting spindle and ensuring long-term stable operation of the equipment. On the other hand, the first expansion module and the second expansion module can work together to integrate metering, feeding, heating and other functions, enriching the functions of the stirring mechanism while achieving weight balance, improving the integration and practicality of the equipment, and expanding the scope of application scenarios of the equipment.

[0018] The present invention will now be described in further detail with reference to the embodiments shown in the accompanying drawings.

[0019] Reference Figure 1-5 As shown, a multi-cylinder dispersing and stirring mechanism with counterweight in this embodiment includes a lifting main shaft 1, a transmission platform 2 mounted on the lifting main shaft 1, a stirrer 3 mounted on the transmission platform 2, and a driver 4 mounted on the transmission platform 2. The stirrer 3 and the driver 4 are respectively located on both sides of the lifting main shaft 1. A first expansion module 51 is also provided on the transmission platform 2 between the stirrer 3 and the lifting main shaft 1. A second expansion module 52 is provided on the transmission platform 2 at the position between the lifting main shaft 1 and the driver 4. The weight of the first expansion module 51 is less than that of the second expansion module 52, and the two cooperate to reduce the weight difference between the two sides of the lifting main shaft 1 on the transmission platform 2. The first expansion module 51 and the second expansion module 52 form a functional cooperation.

[0020] The lifting spindle 1 is vertically installed, and its lower end can be connected to the equipment frame via a bearing seat. The upper end is as described above. Figure 1 As shown, the connection can be made through a rotating mechanism, that is, the end of the lifting spindle 1 is connected to the rotating platform through a swivel support, ensuring that the transmission platform 2 can rise and rotate synchronously with the lifting spindle 1; the agitator 3 is installed on one side of the transmission platform 2 through a bearing seat and a fixed bracket combination, and the agitator shaft of the agitator 3 extends vertically downward for insertion into the mixing cylinder for operation; the driver 4 is a motor, which is fixed to the other side of the transmission platform 2 by a motor seat bolt, and the installation positions of the agitator 3 and the driver 4 are symmetrical about the axis of the lifting spindle 1 or distributed at a preset distance; the first expansion module 51 is installed on the transmission platform 2 through bolt connection to the preset installation area between the agitator 3 and the lifting spindle 1, and the second expansion module 52 is installed on the transmission platform 2 at the position between the lifting spindle 1 and the driver 4. The weight of the first expansion module 51 and the second expansion module 52 is calculated and determined according to the actual weight difference and lever arm difference between the driver 4 and the agitator 3, so that the total weight moment on both sides of the lifting spindle 1 tends to be balanced.

[0021] When the equipment is started, the lifting spindle 1, driven by a hydraulic cylinder or a motor screw drive, rises and falls vertically, thereby driving the transmission platform 2 and the agitator 3, driver 4, first extension module 51, and second extension module 52 mounted on it to rise and fall synchronously, adjusting the relative height of the agitator 3 and the mixing cylinder below. After the agitator 3 is lowered to a suitable mixing position, the driver 4 is powered on, and its output shaft transmits power to the input shaft of the agitator 3 through a preset transmission structure (such as a transmission belt 21 or gears), driving the agitator 3's mixing blades to rotate at high speed, achieving the dispersion and mixing of materials. During this process, due to the weight cooperation of the first extension module 51 and the second extension module 52, the forces on both sides of the lifting spindle 1 are kept as balanced as possible, alleviating the stress on the lifting spindle 1. To prevent bending deformation and shoulder wear caused by excessive force on one side over a long period of time, the service life of the lifting spindle 1 is extended. At the same time, the first expansion module 51 and the second expansion module 52 work together. For example, when the first expansion module 51 is a feeding component, the second expansion module 52 can be a corresponding opening and closing drive module, which improves the integration of the equipment while achieving weight balance. The transmission platform 2 will not tilt or shake due to weight imbalance during lifting and stirring, ensuring that the agitator 3 can be stably inserted into the mixing cylinder for operation, avoiding collision between the agitator and the inner wall of the mixing cylinder, improving the safety and reliability of the stirring operation. Moreover, the setting of the first and second expansion modules does not affect the normal operation of the agitator 3 and the driver 4, ensuring stirring efficiency and making full use of the space of the transmission platform 2.

[0022] In one optional embodiment, the transmission platform 2 includes a transmission belt 21 for connecting the driver 4 and the stirrer 3, and a housing 22 that covers at least the upper and lower sides of the transmission platform 2; the first expansion module 51 is installed on the housing 22 on the upper or lower side of the transmission platform 2.

[0023] The transmission belt 21 of the transmission platform 2 is a rubber synchronous belt with a toothed structure on its inner side. It is respectively fitted onto the driving synchronous pulley on the output shaft of the driver 4 and the driven synchronous pulley on the input shaft of the agitator 3, forming a toothed belt transmission structure to ensure that the power of the driver 4 is transmitted to the agitator 3 without slippage. The housing 22 includes an upper housing 22 and a lower housing 22. The upper housing 22 is bolted to the top frame of the transmission platform 2, covering the upper area of ​​the transmission platform 2. The lower housing 22 is bolted to the bottom frame of the transmission platform 2, covering the lower area of ​​the transmission platform 2. In the transmission belt 21 area, the edge of the housing 22 is provided with a flanged structure to improve the structural strength and prevent dust, material debris and other impurities from entering the area. If the first expansion module 51 is installed on the upper side of the corresponding transmission platform 2 of the housing 22, a threaded hole can be opened at the preset installation position of the upper housing 22, and the base of the first expansion module 51 is fastened to the threaded hole by an internal hex bolt. If it is installed on the lower housing 22, a nut seat can be welded on the lower housing 22, and the first expansion module 51 is connected to the nut seat by bolts, and the weight of the first expansion module 51 is evenly transmitted to the transmission platform 2 through the housing 22.

[0024] In another embodiment, the transmission platform 2 includes a transmission belt 21 for connecting the driver 4 and the stirrer 3, and a housing 22 that covers at least both sides of the transmission platform 2; the first extension module 51 is mounted on the housing 22.

[0025] In addition, a connector 23 is provided on the housing 22. The connector 23 is located on the upper or lower side of the transmission belt 21 and extends from the housing 22 to the other side of the housing 22 corresponding to the transmission belt 21, and is used to connect the first expansion module 51.

[0026] The connector 23 is made of a rectangular steel plate. One end of the connector 23 is fixedly connected to the inner wall of the housing 22 by welding (taking the housing 22 as the left housing 22 as an example, one end of the connector 23 is welded to the upper part of the inner wall of the left housing 22). The other end extends to the other side (i.e., the right side) of the housing 22 corresponding to the transmission belt 21. The extension length is determined according to the width of the transmission belt 21, ensuring that the extension end of the connector 23 can cross over the top of the transmission belt 21 (the connector 23 is located on the upper side of the transmission belt 21) and protrude. The extension end of the connector 23 has two symmetrically distributed mounting holes with internal threads for connecting with the expansion module 5. The base of the expansion module 5 has through holes corresponding to the mounting holes. Bolts are threaded through the through holes and connected to the mounting holes of the connector 23 to fix the expansion module 5 to the connector 23, thereby installing the expansion module 5 in the right area of ​​the transmission belt 21. The connector 23 allows the expansion module 5 to cross the transmission belt 21 and be installed in an area that was originally inaccessible.

[0027] To make the installation of the first expansion module 51 more convenient, a top-opening mechanism 6 is also provided in the transmission platform 2 at the position between the first expansion module 51 and the lifting spindle 1 and / or between the first expansion module 51 and the agitator 3. The top-opening mechanism 6 is used to push the transmission belt 21 to both sides to increase the installation space of the first expansion module 51.

[0028] When the space inside the transmission platform 2 is compact and the gap between the transmission belt 21 and the lifting spindle 1 and the agitator 3 is small, the opening mechanism 6 actively opens the transmission belt 21 to provide sufficient installation space for the first expansion module 51, avoiding friction or collision between the first expansion module 51 and the transmission belt 21. The opening mechanism 6 is installed inside the transmission platform 2 and does not affect the external structure of the equipment. While achieving weight balance, it ensures that the transmission belt 21 can transmit power normally, and the driver 4 can still stably drive the agitator 3 to operate, ensuring the continuity and reliability of the mixing operation, and further improving the practicality and operability of the equipment.

[0029] Preferably, the transmission belt 21 is a belt, and both the agitator 3 and the driver 4 are connected to the belt via pulleys to form a transmission. The opening mechanism 6 includes at least two pulleys, which are used to open the belt to positions away from each other on both sides.

[0030] The transmission belt 21 is a rubber V-belt. A driven V-belt pulley is installed on the input shaft of the agitator 3, and a driving V-belt pulley is installed on the output shaft of the driver 4. The V-belt is fitted onto the driving and driven pulleys to form a V-belt transmission structure. The two pulleys of the opening mechanism 6 are both V-shaped guide pulleys. The grooves of the pulleys are adapted to the cross-section of the V-belt. The two guide pulleys are installed on both sides of the installation area of ​​the first expansion module 51 in the transmission platform 2 through the pulley axle and the fixed bracket. The fixed bracket is fixed to the frame of the transmission platform 2 by bolts. The pulley axles of the two guide pulleys are arranged in parallel and are located on the inner side of the V-belt (closer to the center of the transmission platform 2). The guide pulleys can rotate freely around the pulley axle. During installation, the grooves of the two guide pulleys fit against the inner side of the V-belt, and the distance between the two guide pulleys is greater than the distance between the driving and driven pulleys in this area, thereby opening the V-belt to both sides (away from each other), so that the belt forms an outward tension in this area, expanding the installation space inside the belt.

[0031] In an optional embodiment, the first expansion module 51 includes one or more of the following: a metering component for metering feed, a feeding component 7 for guiding feed, a heating component 8 for heating the feed medium, and a storage component for storing the medium; the second expansion module 52 includes a power supply or control drive module corresponding to the metering component, an opening and closing drive module corresponding to the feeding component 7, a temperature control module corresponding to the heating component 8, and a discharge control module corresponding to the storage component, etc., and its weight is greater than that of the first expansion module 51. The two work together to reduce the weight difference on both sides of the lifting spindle 1 and form a functional cooperation.

[0032] When the first expansion module 51 is a metering component: the metering component uses a miniature weighing sensor, which is mounted on the transmission platform 2 above the feed inlet of the mixer 3 via a bracket. A feed funnel is placed on the weighing platform of the weighing sensor. During operation, the material is poured into the feed funnel, and the weighing sensor detects the weight of the material in real time and transmits the weight signal to the control system. When the weight of the material reaches the preset value, the control system sends a signal to prompt the operator to stop feeding, ensuring that the amount of material entering the mixer 3 each time is accurate and controllable. During this process, the weight of the weighing sensor (i.e., the weight of the first expansion module 51) and the second expansion module 52 (such as the power supply control module) work together to compensate for the weight difference on both sides of the lifting main shaft 1, while accurately measuring the feed amount, ensuring the accurate proportion of the mixed material and improving the consistency of the quality of the mixed product.

[0033] When the first expansion module 51 is the feeding assembly 7: The feeding assembly 7 includes a stainless steel feeding pipe and a funnel-shaped feeding port. One end of the feeding pipe is welded and fixed to the feeding port, and the other end is bolted to the feeding port of the agitator 3 through a flange. During operation, the material is poured in through the feeding port and guided directly into the container through the feeding pipe, avoiding spillage of material during feeding, reducing material waste, and improving feeding efficiency. The weight of the feeding assembly 7 can be designed according to balance requirements and cooperates with the second expansion module 52 (such as a pneumatic valve module) to compensate for the weight difference on both sides of the lifting main shaft 1 while realizing the feeding guidance function, ensuring the main shaft is balanced. The feeding assembly 7 is directly connected to the feeding port of the agitator 3, with a compact structure that does not occupy extra space and improves the integration of the equipment.

[0034] When the first expansion module 51 is the heating component 8: the heating component 8 is an electric heating tube, which is wrapped around the outside of the stirring shaft of the stirrer 3 by a metal bracket; when the material to be stirred requires a specific temperature environment, the temperature control system (second expansion module 52) controls the electric heating tube to be energized and heated, and the heat is transferred to the stirring shaft, thereby heating the material near the stirring shaft, so that the material temperature reaches the preset value; the weight of the heating component 8, in conjunction with the second expansion module 52 (temperature control module), can effectively compensate for the weight difference on both sides of the lifting main shaft 1, while meeting the high temperature stirring requirements and expanding the applicable range of the equipment (such as heating and dissolving certain solid materials). Of course, the heating component 8 can also heat the feed hopper, heat and melt the medium, and then introduce the medium into the container through the hopper.

[0035] The second expansion module 52 can also be a storage component: the storage component is a small stainless steel storage tank, which is fixed on the transmission platform 2 by a bracket. The bottom outlet of the storage tank is connected to a hose through a valve, and the other end of the hose is connected to the first expansion module (hopper). Before operation, sufficient material can be pre-loaded into the storage tank. During the mixing operation, the valve of the storage component can be opened to transport the material through the hose and the first expansion module, reducing the waiting time for frequent feeding and improving the continuity of the mixing operation. The weight of the storage tank can be selected according to the balance requirements. While realizing the material storage function, it balances the weight on both sides of the lifting main shaft 1 to avoid uneven force on the main shaft. The capacity of the storage tank can be designed according to the mixing requirements, further improving the practicality and flexibility of the equipment.

[0036] The above describes a multi-cylinder dispersing and stirring mechanism with counterweight, which can be applied in stirring equipment.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
