Description

Technical Field

[0001] The present invention relates to the technical field of transmission belt production, and particularly to an integrated production equipment for continuous mixing and refining of transmission belts with switchable process modes. Background Art

[0002] As a core component of the mechanical transmission system, in the manufacturing process of transmission belts, the mixing and refining links directly determine the material uniformity and finished product performance. The traditional production mode generally adopts a split equipment design, where the mixer and the refiner operate independently, and the material needs to be transferred in the middle to complete the two-stage processing. This design causes the high-temperature material after mixing to rapidly cool down due to exposure to the external environment during the transfer process, leading to heat loss problems. This not only affects the plasticizing effect of the subsequent refining process but also may cause a decrease in the stability of the material molecular chain structure, ultimately reducing the fatigue resistance and service life of the product. In addition, the split equipment requires an independent drive system, which has high energy consumption and complex coordinated control. The process switching relies on manual intervention, and frequent shutdown adjustments seriously restrict the production efficiency.

[0003] In the prior art, some improvement schemes attempt to improve the efficiency through structural integration. For example, the patent with publication number CN213035013U discloses an integrated equipment with two mixing pipes, which adopts a single motor to drive a two-stage mixing structure. Although the mixing cycle is shortened, its design is still limited to a single process stage and does not solve the problem of continuous connection between mixing and refining. In addition, the transmission structure of this equipment is fixed, unable to flexibly switch the operation mode according to the process requirements, and lacks the ability to monitor the material state in real time and dynamically adjust. Summary of the Invention

[0004] Aiming at the problems of heat loss, high energy consumption, and poor process flexibility caused by split equipment in the traditional transmission belt production process, the present invention provides an integrated production equipment for continuous mixing and refining of transmission belts with switchable process modes.

[0013] Preferably, the automatic batching system includes a batching and metering device. A vibrating feeder is provided inside the batching and metering device. An electronic scale metering system is provided at the bottom of the vibrating feeder.

[0014] Preferably, a programmable logic controller and a human-machine interface are provided inside the bracket.

The programmable logic controller dynamically adjusts the mixing and refining process parameters according to the sensor feedback data and realizes seamless switching of the process mode through the integrated transmission mechanism.

[0015] Working principle: The working principle of the present invention is based on the synergistic effect of the integrated transmission mechanism and the intelligent closed-loop control system to realize the continuous and efficient operation of the mixing and refining processes in the production process of the transmission belt. The raw materials and additives are stored in the first storage tank and the second storage tank respectively. After being accurately proportioned by the vibrating feeder and the electronic scale metering system of the automatic batching system, they enter the mixing device for preliminary mixing. The mixed material directly falls into the feed inlet of the mixer to start the processing process.

[0016] The power of the driving motor is transmitted to the connecting pipe through the transmission shaft. The fourth gear and the first gear fixed at both ends of the connecting pipe can slide along the axial direction of the transmission shaft, and their positions are controlled by the electric push rod, so as to realize the flexible switching of the three modes of mixing, blending and refining. In the mixing mode, the electric push rod pushes the fourth gear to mesh with the third gear of the mixer, and the power of the driving motor is transmitted to the second rotating shaft of the mixer through the transmission shaft and the fourth gear, and the material is subjected to high-temperature shear mixing; at this time, the first gear is separated from the second gear, and the refiner is suspended. When mixing and refining need to be performed simultaneously, the electric push rod adjusts the position to keep the fourth gear meshing, and the first gear slides to mesh with the second gear. The power of the driving motor is transmitted in two ways: one way drives the mixer through the fourth gear, and the other way drives the first sprocket of the refiner through the first gear, the second sprocket and the chain, so as to realize dual process parallel. In the refining mode, the electric push rod pulls the fourth gear out of the third gear, and the first gear is completely meshed with the second gear. The power of the driving motor completely drives the refiner through the sprocket chain assembly, and the mixed material is roller-pressed and refined.

[0017] The intelligent closed-loop control system collects process data in real time through multiple sensors: temperature sensors monitor the material temperature in the mixer and refiner, pressure sensors feedback material pressure changes, online viscometers detect material fluidity, and online component analyzers verify the additive ratio. After integrating the above data, the programmable logic controller (PLC) dynamically adjusts the speed of the drive motor to optimize the mixing intensity and refining effect, controls the stroke of the electric push rod to switch the transmission mode, and links the batching system to correct the raw material ratio. After the mixing is completed, the PLC automatically triggers the electric push rod to switch to the refining mode, and the material falls directly onto the surface of the refiner roller through the vertical layout of the equipment, avoiding heat loss caused by intermediate transfer and ensuring seamless process connection.

[0018] The refined finished product is exported through the receiving plate to complete the continuous production process. The PLC adjusts the motor load according to the real-time working conditions to reduce energy consumption in the standby or low-load stage; the vertical layout of the mixer and refiner combined with the heat insulation design further reduces heat loss.

[0019] The beneficial effects of the present invention are:

[0020] By vertically integrating and directly connecting the mixer and refiner, the significant heat loss generated by traditional split equipment during material transfer is completely eliminated, and the optimal temperature required for material processing is effectively maintained, which not only improves the plasticizing effect in the refining stage, but also helps to stabilize the molecular chain structure of the material, thereby significantly improving the fatigue resistance and service life of the final drive belt product. At the same time, the use of a single drive motor with a switchable integrated transmission mechanism not only simplifies the drive system and reduces the total installed power of the equipment, but also combines the intelligent adjustment of the motor load according to the real-time working conditions of the PLC, which can effectively reduce energy consumption in the standby or low-load stage, achieving significant energy-saving effects. The equipment can quickly and automatically switch between mixing, refining and mixing and refining synchronous modes through the combination of gears and sprockets controlled by electric push rods, greatly improving the flexibility of the production process, being able to adapt to the production needs of products with different formulas and specifications, reducing the downtime caused by mode switching, and significantly improving production efficiency.

[0021] In addition, the integrated automatic batching system and the temperature, pressure, viscosity and composition sensors at key nodes constitute a precise closed-loop control system that can monitor the material status in real time and dynamically adjust the process parameters by PLC, ensuring the accuracy of the raw material ratio and the stability of the processing process, greatly improving the homogeneity and quality consistency of the product, and reducing the defective rate. Automated operation reduces manual intervention, reduces the risk of operational errors, and improves the safety and reliability of the production process. Finally, the overall structure of the equipment is compact, and the vertical layout effectively saves floor space and facilitates the overall planning and integration of the production line.

The two are vertically arranged in the support 4 to eliminate heat loss during the material transportation process. A receiving plate 8 is arranged at the bottom of the refining machine 7. A support structure is arranged at the bottom of the receiving plate 8.

[0031] Specifically, the support 4 can play a role in supporting the internal structure. The first storage tank 1 can store the basic rubber materials.

This vertical integrated layout is one of the key structural features of the present invention, aiming to solve the heat loss problem caused by the transfer of split equipment in the background technology.

[0032] Please refer to the attached Figure 1 - attachedFigure 2 , the support structure includes a support bar 9, and the outer wall of the support bar 9 is fixedly connected to the bottom inner wall of the bracket 4.

[0033] Specifically, the support bar 9 can play a role in supporting the material receiving plate 8.

[0034] The core innovation of the present invention is that the internal mixer 6 and the refining machine 7 are connected by an integrated transmission mechanism. The integrated transmission mechanism is the key to realizing the switching of different process modes, and it includes a switchable gear meshing assembly and a sprocket chain assembly, which are used to realize the continuous, independent or synchronous operation modes of the mixing and refining processes under the drive of a single drive motor 5.

[0035] Specifically, a transmission shaft 11 is fixedly arranged at the output end of the drive motor 5. The transmission shaft 11 is rotatably connected to the inside of the bracket 4, and a rack is arranged on the outer wall of the transmission shaft 11. A connecting pipe 12 is movably sleeved on the outer wall of the transmission shaft 11, and a fourth gear 21 and a first gear 13 are fixedly connected to both ends of the connecting pipe 12. Tooth grooves meshing with the rack on the outer wall of the transmission shaft 11 are opened inside the fourth gear 21, the connecting pipe 12 and the first gear 13, so that the connecting pipe 12 and the gears at both ends thereof can slide along the axial direction of the transmission shaft 11.

[0036] A chute 25 is opened on the side wall of the first gear 13. Through holes 26 are opened inside the fourth gear 21 and the chute 25, and the through holes 26 are communicated with the internal holes of the connecting pipe 12, allowing the transmission shaft 11 to pass through.

[0037] To realize the axial sliding of the connecting pipe 12 to switch the transmission mode, an electric push rod 10 is arranged on the upper part of the transmission shaft 11. One side of the electric push rod 10 away from the output end is fixedly connected to the inner wall of the bracket 4, and its output end is fixedly connected to a fixed frame 23. A top column 24 is fixedly connected to the bottom inside of the fixed frame 23, and the end of the top column 24 is clamped into the chute 25 of the first gear 13. By controlling the telescopic movement of the electric push rod 10 through the PLC, the connecting pipe 12 and the first gear 13 and the fourth gear 21 can be accurately driven to move to a predetermined position along the transmission shaft 11, realizing the meshing or separation of different gears and sprockets.

[0038] A second rotating shaft 17 is arranged inside the internal mixer 6. The second rotating shaft 17 is rotatably connected to the outer wall of the bracket 4 or the body of the internal mixer, and a third gear 15 is fixedly connected to the outer wall of the second rotating shaft 17. In the mixing or synchronous mode, the electric push rod 10 pushes the connecting pipe 12, so that the tooth ends of the fourth gear 21 and the third gear 15 are meshed with each other, and the power of the drive motor 5 is transmitted to the third gear 15 through the transmission shaft 11, the connecting pipe 12 and the fourth gear 21, and then drives the second rotating shaft 17 to rotate, driving the internal mixer 6 to carry out mixing work.

[0039] Inside the refining machine 7, a third rotating shaft 20 is provided. The third rotating shaft 20 is rotatably connected to the outer wall of the support 4 or the refining machine body. A first sprocket 19 is fixedly connected to the outer wall of the third rotating shaft 20.

[0040] Specifically, the third rotating shaft 20 can play a role in connecting the rotating structure of the refining machine 7, such as a roller. Through the first sprocket 19, power can be transmitted to the third rotating shaft 20, thereby driving the refining machine 7 to perform the refining work.

[0041] To transmit power to the refining machine 7, an intermediate transmission assembly is provided. A second gear 14 is provided on the side of the third gear 15 away from the mixing machine 6. The middle of the second gear 14 is rotatably connected to the outer wall of the first rotating shaft 16. One end of the first rotating shaft 16 away from the second gear 14 is fixedly connected to the inner wall of the support 4. A second sprocket 22 is fixedly connected to the side of the second gear 14 away from the third gear 15. The first sprocket 19 and the second sprocket 22 are connected by a chain 18.

[0042] Specifically, when refining or synchronous operation is required, the electric push rod 10 controls the movement of the connecting pipe 12, so that the first gear 13 meshes with the second gear 14. At this time, the power of the driving motor 5 can be transmitted to the second gear 14 through the transmission shaft 11, the connecting pipe 12, and the first gear 13. The second gear 14 drives the coaxial second sprocket 22 to rotate. The second sprocket 22 transmits the power to the first sprocket 19 of the refining machine 7 through the chain 18, thereby driving the refining machine to work.

[0043] To achieve intelligent control and precise monitoring of the production process, this equipment integrates an advanced sensing system and a control system. An automatic batching system is provided inside the second storage tank 3 and the first storage tank 1. This system includes a batching metering device, which is internally provided with a vibrating feeder and an electronic scale metering system at the bottom to ensure that the raw materials and additives are accurately proportioned according to the preset formula.

[0044] A variety of sensors are provided at key process points: temperature sensors are provided inside the screw, on the barrel wall, and at the material outlet of the mixing machine 6, and on the surface of the rollers of the refining machine 7 to detect the temperature of the material and key parts of the equipment in real time; pressure sensors are provided between the material inlet and outlet of the mixing machine 6 and between the rollers of the refining machine 7 to monitor the pressure change of the material during the processing in real time; an on-line material composition analyzer is provided at the outlet of the mixing machine 6 to detect the components of the material and the dispersion uniformity of the additives in real time or periodically; an on-line viscometer is installed in the material pipeline of the mixing machine 6 and near the outer wall or the discharge port of the refining machine 7 to detect the viscosity change of the material in real time and reflect the degree of plasticization.

[0045] The support 4 is provided with a core control unit including a programmable logic controller PLC and a human-machine interface. The PLC is electrically connected and communicates data with the automatic batching system, all the temperature sensors, pressure sensors, online material component analyzers, online viscometers, drive motors 5 and electric push rods 10 through wires or buses.

[0046] Specifically, the PLC constitutes the intelligent closed-loop control core of the equipment. It receives real-time data from various sensors, and dynamically adjusts the speed of the drive motor 5 to affect the shear rate and energy input according to the preset process parameter model and control algorithm, controls the stroke of the electric push rod 10 to achieve automatic switching of mixing, refining and synchronization modes, and can be linked to the automatic batching system for fine-tuning. The human-computer interaction interface is used for operators to set process parameters, monitor production status and receive alarm information.

[0047] Working principle:

[0048] The working principle of the present invention is based on the synergy of the integrated transmission mechanism and the intelligent closed-loop control system, so as to realize the continuous, automatic, intelligent and efficient operation of the mixing and refining processes in the production process of the transmission belt.

[0049] The raw materials and additives are stored in the first storage tank 1 and the second storage tank 3 respectively. After the accurate proportioning is completed by the vibrating feeder of the automatic batching system and the electronic scale metering system, they enter the mixing device 2 for preliminary mixing. The mixed materials fall directly into the feed port of the mixer 6 below by gravity, and the processing process begins.

[0050] After the drive motor 5 is started, the power is transmitted through the transmission shaft 11. The PLC controls the action of the electric push rod 10 according to the preset program or real-time instructions, pushes or pulls the connecting tube 12 to move axially along the transmission shaft 11, and accurately locates the positions of the first gear 13 and the fourth gear 21, thereby realizing flexible switching of the three main process modes:

[0051] Mixing mode: The electric push rod 10 pushes the connecting tube 12 to make the fourth gear 21 mesh with the third gear 15 of the mixer 6, while ensuring that the first gear 13 is separated from the second gear 14. At this time, all the power of the drive motor 5 is used to drive the mixer 6 to perform high-temperature shear mixing on the material. The refiner 7 does not operate.

[0052] Mixing and refining synchronous mode: the electric push rod 10 adjusts the connecting pipe 12 to the middle position, so that the fourth gear 21 is kept meshing with the third gear 15, and the first gear 13 is also slid to mesh with the second gear 14. At this time, the power of the driving motor 5 is divided into two ways: one way drives the mixer 6 through gear transmission, and the other way drives the refiner 7 through gear chain transmission, so that the mixing and refining processes can be carried out simultaneously to maximize production efficiency.

[0053] Refining mode: The electric push rod 10 pulls the connecting pipe 12 to completely disengage the fourth gear 21 from the third gear 15, while ensuring that the first gear 13 is fully meshed with the second gear 14. At this time, the power of the drive motor 5 completely drives the refining machine 7 to operate through the chain drive system, which is used to refine the material that has been kneaded or to perform a separate refining operation.

[0054] During the entire processing process, the intelligent closed-loop control system continuously operates: Temperature, pressure, viscosity, and composition sensors throughout the equipment continuously collect key process parameters and transmit the data to the PLC. The PLC compares these real-time feedback data with the preset process target values and dynamically adjusts the speed of the drive motor 5 through advanced control algorithms such as PID control to precisely control the shear rate, energy input, and material temperature during the kneading and refining processes; at the same time, the PLC may also, based on the material composition or viscosity feedback, instruct the automatic batching system to fine-tune the formula for subsequent batches to achieve adaptive optimization of the process.

[0055] For the kneaded material, since the kneading machine 6 and the refining machine 7 are vertically arranged and directly connected, the material directly falls into the rolls of the refining machine 7 by gravity or short-distance conveying for refining, almost completely avoiding the significant heat loss and potential pollution caused by intermediate transfer in the traditional process, ensuring the continuity of the process and the stability of the material temperature. An insulating cover can be installed outside the equipment to further reduce heat dissipation.

[0056] The refined finished rubber compound is exported through the receiving plate 8 at the bottom, completing the entire continuous and integrated production process. The PLC can also intelligently adjust the motor energy consumption according to real-time working conditions such as load and mode, reducing power consumption during standby or low-load stages to achieve energy-saving operation.

[0057] Although the embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions, and variations can 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.
