Description

Technical Field

[0001] This invention relates to the field of antioxidant delivery technology, and more specifically to a feeding device for antioxidant production. Background Technology

[0002] In the production process of antioxidants, the feeding device is a key link in conveying various raw materials to the reactor or mixing equipment according to process requirements. There are many types of raw materials for antioxidants, which can be mainly divided into three categories according to their physical forms: solid powders, such as butylated hydroxyanisole, dibutyl hydroxytoluene, tert-butylhydroquinone, etc.; granular materials, such as compound granules, carrier granules, etc.; and liquid raw materials, such as solvents, liquid additives, etc. These three forms of raw materials need to be introduced into the reaction system in a precise ratio and sequence to ensure the final quality and reaction efficiency of the antioxidant.

[0003] Currently, for the feeding operations of the above three different forms of raw materials, large-scale production enterprises generally adopt a split and independently configured feeding mode, that is: solid powder and granular materials are transported by screw conveyors, belt conveyors or bucket elevators, while liquid raw materials are transported through pumping systems and independent pipelines. This traditional feeding method with multiple devices in parallel and decentralized control has the following technical defects in practical applications: In the production of antioxidants, solid and liquid raw materials must enter the reactor in a strict sequence to ensure premixing effect and reaction uniformity. However, traditional split feeding is driven by multiple motors, and the start-up, stop and running speed of each device depends on complex PLC program coordination control. In actual production, due to program response delay, signal interference or equipment inertia differences, the solid material has reached the end while the liquid has not yet arrived, or the liquid has been drained while the solid is still being conveyed. This asynchronous start-up and stop phenomenon directly causes the timing of material entering the reactor to be disordered, affecting the accuracy of the ratio and the reaction effect. Some liquid raw materials contain undissolved solid additives or functional powders, such as anti-caking agents and stabilizers. These particles will gradually sink due to gravity when left to stand, resulting in a thinner upper liquid composition and particle accumulation in the lower layer. At the same time, some liquid raw materials are water-oil two-phase emulsions, which are prone to demulsification or stratification if left to stand for too long, with the upper layer being the light phase and the lower layer being the heavy phase, resulting in uneven component distribution. In traditional feeding devices, liquid raw materials are usually directly extracted by a pumping system. If the liquid raw materials are not continuously stirred and the upper or lower liquid is directly extracted for feeding, the composition of the liquid raw materials entering the reactor will deviate from the formulation requirements, ultimately affecting the reaction uniformity of the antioxidant and the consistency of the product. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a feeding device for antioxidant production, thereby solving the problems mentioned in the background section.

[0005] The above-mentioned technical objective of the present invention is achieved through the following technical solution: A feeding device for antioxidant production includes: a feeding rack with a conveyor belt inside, and an operating frame fixedly mounted on the top surface of the feeding rack; a feeding assembly disposed inside the feeding rack for synchronous feeding of different antioxidant production raw materials, the feeding assembly including: a rotating shaft movably sleeved inside the feeding rack, a drive shaft, a tensioning column, and a driven shaft movably sleeved inside the feeding rack, the conveyor belt being wound around the outside of the rotating shaft, the drive shaft, the tensioning column, and the driven shaft, a servo motor fixedly mounted on the bottom surface of the feeding rack, and pulleys fixedly mounted on one end of the drive shaft of the servo motor and one end of the drive shaft, respectively. A V-shaped belt is wound around the outer circular wall of the pulley. A partition plate is fixedly installed on the inner top surface of the operating frame. An inclined block is fixedly installed on one side of the partition plate and one side of the inner surface of the operating frame. A raw material shell is fixedly installed on the top surface of the operating frame. Heating grooves are opened on both sides of the partition plate and both sides of the inner surface of the operating frame. Heating wires and heat-conducting plates are fixedly installed inside the heating grooves. A stirring assembly for agitating liquid raw materials used in antioxidant production is provided inside the raw material shell. A connecting assembly for simultaneously feeding different raw materials is provided on one side of the feeding rack. A tapping assembly for breaking up agglomerated raw materials is provided on the top surface of the operating frame.

[0006] By adopting the above technical solution, the partition plate, due to the different types of raw materials used in antioxidant production (solid powder, granules, and liquid raw materials), divides the internal space of the operating frame into two independent spaces. Therefore, the surface space of the conveyor belt is also divided into two spaces. Workers can then place solid powder and granules onto the top surface of the conveyor belt through these two independent spaces. A servo motor drives the pulleys, which rotate synchronously via a V-belt. This rotation, in turn, drives the drive shaft, causing the conveyor belt to move across the surfaces of the rotating shaft, drive shaft, and driven shaft, allowing for the synchronous feeding of solid powder and granules. Simultaneously, workers can place liquid raw materials into the raw material shell for feeding. When the ambient humidity is high, the solid powder and granules become damp and clump together. In this case, workers use a heating wire; the heat generated by the wire is conducted to a heat-conducting plate, and then diffuses within the operating frame, facilitating the drying of the damp solid powder and granules.

[0007] Preferably, the stirring assembly includes: a central column, which is movably sleeved inside the raw material shell, stirring blades are fixedly sleeved on the outer circular wall of the central column, and a liquid inlet pipe is fixedly installed on the top surface of the raw material shell, the liquid inlet pipe extending into the interior of the raw material shell.

[0008] By adopting the above technical solution, after the liquid raw material is placed into the inside of the raw material shell by the set stirring blades, the liquid raw material is temporarily stored in the shell. In order to prevent the suspended matter in the liquid raw material from settling or the emulsion from separating, and to ensure that the composition is uniform and stable, the rotating central column drives the stirring blades to rotate continuously, so as to continuously stir the liquid raw material in the raw material shell.

[0009] Preferably, the connecting assembly includes: a fixed plate, the fixed plate being fixedly installed on one side of the feeding rack, a rotating sleeve being fixedly installed on the side of the feeding rack near the fixed plate, a rotating column being movably sleeved inside the rotating sleeve, first transmission wheels being fixedly sleeved on the outer circular walls of the drive shaft and the rotating column respectively, a first transmission belt being wound around the outer circular walls of the two first transmission wheels, a first bevel gear being fixedly installed at the end of the rotating column away from the feeding rack, a movable column being movably sleeved inside the fixed plate, a second bevel gear being fixedly installed at the end of the movable column near the first bevel gear, the second bevel gear meshing with the first bevel gear, sprockets being fixedly sleeved on the outer circular walls of the central column and the movable column respectively, and a chain being meshed on the outer circular walls of the two sprockets.

[0010] By adopting the above technical solution, through the set sprocket, when the drive shaft of the servo motor rotates, it drives the pulley and V-belt to rotate. The pulley drives the drive shaft to rotate, so that the conveyor belt moves on the surface of the rotating shaft, drive shaft and driven shaft. At the same time, the rotation of the drive shaft drives the first transmission wheel to rotate. Then, the two first transmission wheels will rotate synchronously through the first transmission belt. Then, the first transmission wheel will drive the rotating column and the first bevel gear to rotate. The rotation of the first bevel gear meshes with and drives the second bevel gear to rotate. The rotation of the second bevel gear drives the movable column and the sprocket to rotate. Then, the two sprockets rotate synchronously through the connection of the chain. When the sprocket rotates, it drives the central column and the stirring blade to rotate. At this time, the rotation of the conveyor belt and the stirring blade starts at the same time, so that solid powder, granular material and liquid raw materials can be moved and fed synchronously.

[0011] Preferably, a humidity sensor is fixedly mounted on the top surface of the operating frame and extends into the interior of the operating frame.

[0012] By adopting the above technical solution, a humidity sensor is installed to detect the humidity inside the operating frame.

[0013] Preferably, the feeding rack has two support frames fixedly installed externally, the two support frames are symmetrically arranged, a linear motor is fixedly installed on the top surface of the support frame, a stabilizing frame is fixedly installed on the top surface of the two linear motor slides, two connecting rods are fixedly installed on the side of the stabilizing frame near the feeding rack, a push plate is fixedly installed on the end of the connecting rod away from the stabilizing frame, two movable holes are opened on the side of the operating frame near the stabilizing frame, the movable holes are movably connected to the connecting rods, the two connecting rods are of different lengths, and the two push plates are respectively located on both sides of the partition plate.

[0014] By adopting the above technical solution, when the humidity sensor detects that the humidity inside the operating frame is high, the operator uses a linear motor. After the linear motor is started, its slide will drive the stabilizer to move towards the position of the operating frame. Then the stabilizer will push the connecting rod and the push plate to move. At this time, the push plate moves inside the operating frame and pushes the solid powder and granules closer to the heating wire and heat conduction plate, so that the solid powder and granules can be brought closer to the heat source in a high humidity environment, so that they can be dried quickly.

[0015] Preferably, the striking assembly includes: a drive motor, which is fixedly mounted on the top surface of the operating frame. The top surface of the operating frame has two pre-reserved openings, and a mounting bracket is fixedly mounted inside the pre-reserved openings. A linkage rod is provided between the two mounting brackets. The linkage rod movably passes through the mounting bracket and is fixedly mounted to the drive shaft of the drive motor. A cam is fixedly sleeved on the outer circular wall of the linkage rod. A support column is fixedly mounted inside the mounting bracket. An L-shaped column is movably sleeved on the outer circular wall of the support column. A force-bearing plate is fixedly mounted on the top surface of the L-shaped column. An extension rod is fixedly mounted on one side of the L-shaped column. A striking hammer is fixedly mounted on the end of the extension rod away from the force-bearing plate.

[0016] By adopting the above technical solution, and through the setting of the tapping hammer, after the solid powder and granules are dried, the operator uses a drive motor. The drive shaft of the drive motor rotates, which drives the linkage rod to rotate. In turn, the linkage rod drives the cam to rotate. When the protruding end of the cam rotates to the position of the force plate, the cam presses down on the force plate. In turn, the force plate drives the top of the L-shaped column to move downward. At this time, the L-shaped column rotates around the support column. The end of the L-shaped column connected to the extension rod and the tapping hammer will tilt upward, and the tapping hammer will also lift upward away from the surface of the conveyor belt. When the protruding position of the cam moves away from the position of the force plate, the pressure on the force plate is released, and the tapping hammer drives the natural extension rod to fall. In turn, the tapping hammer will hit the surface of the conveyor belt. Through the continuous rotation of the cam, the tapping hammer is continuously raised and lowered, which facilitates the tapping of the dried solid powder and granules, so as to disperse the clumps of solid powder and granules.

[0017] Preferably, the top surface of the operating frame is provided with a connecting pipe, the connecting pipe is fixedly installed with the raw material shell and extends into the interior of the raw material shell, a metering pump is fixedly installed on the top surface of the operating frame, the connecting pipe is fixedly sleeved with the water inlet of the metering pump, a liquid outlet pipe is fixedly installed on the top surface of the operating frame, the liquid outlet pipe is fixedly sleeved with the water outlet of the metering pump, a PLC controller is fixedly installed on one side of the feeding rack, the PLC controller is electrically connected to the servo motor, the PLC controller is electrically connected to the metering pump, and the PLC controller is electrically connected to the humidity sensor and the heating wire respectively.

[0018] By adopting the above technical solution, when the liquid raw material inside the raw material shell reaches the end through the liquid outlet pipe, the liquid raw material will be discharged through the connecting pipe and enter the metering pump. The metering pump can determine the amount of liquid raw material discharged, and then discharge it through the liquid outlet pipe, thereby facilitating the control of the amount of liquid raw material discharged.

[0019] Preferably, a premixing hopper is fixedly installed on the side of the feeding rack away from the rotating shaft, a stirring column is movably sleeved inside the premixing hopper, a plurality of mixing blades are fixedly installed on the outer circular wall of the stirring column, a second drive wheel is fixedly installed on one end of the driven shaft and one end of the stirring column, a second drive belt is wound around the outer circular wall of the two second drive wheels, and a feeding hose is fixedly installed on the side of the premixing hopper away from the feeding rack, the feeding hose extending into the interior of the premixing hopper.

[0020] By adopting the above technical solution, through the premixing hopper, when solid powder and granular materials pass through the inside of the operating frame, they will fall into the premixing hopper simultaneously with the liquid raw materials. While the conveyor belt is rotating and conveying, the drive shaft, rotating shaft, and driven shaft will continue to rotate. When the driven shaft rotates, it will drive the second drive wheel to rotate. Then, the two second drive wheels will rotate simultaneously through the second drive belt. The rotation of the second drive wheel will drive the stirring column and mixing blades to rotate, thereby facilitating the premixing of the solid powder, granular materials, and liquid raw materials that enter the premixing hopper simultaneously. When the solid powder, granular materials, and liquid raw materials are conveyed simultaneously, the stirring column and mixing blades will rotate and mix synchronously. When the solid powder, granular materials, and liquid raw materials stop being conveyed, the stirring column and mixing blades will also stop mixing simultaneously.

[0021] In summary, the present invention has the following main beneficial effects: 1. This invention uses partition plates to divide the conveyor belt into sections, and with independent liquid conveying channels and raw material shells, one device can complete the synchronous conveying of solid powder, granular material and liquid raw materials, replacing the traditional three independent devices. In traditional separate conveying, there is a time difference in the start and stop of each device, which leads to inconsistent timing of material entering the reactor and affects the accuracy of proportioning. This device uses the same servo motor to drive the conveyor belt and metering pump to run synchronously, ensuring that solid and liquid raw materials start, are conveyed and arrive at the end at the same time, laying the foundation for subsequent accurate proportioning and mixing. The partition plates strictly separate solid powder and granular material on the conveyor belt to avoid mixing of different solid materials during the conveying process and ensure the purity of raw materials.

[0022] 2. This invention achieves mechanical linkage between the sprocket and transmission assembly and the conveyor belt carrying solid powder and granules. When the servo motor drives the conveyor belt, power is transmitted to the central column via the first transmission wheel, the first bevel gear, the second bevel gear, and the sprocket, causing the stirring blades to start, run, and stop synchronously with the conveyor belt. As the solid powder and granules are conveyed forward on the conveyor belt, the stirring blades simultaneously stir the liquid material inside the raw material shell, ensuring that the liquid material remains uniform during the waiting period. Through the continuous rotation of the stirring blades, the liquid material remains in a flowing state inside the raw material shell, the granules are uniformly suspended, and the emulsion remains stable, ensuring that each portion of liquid material extracted has a uniform composition. This achieves active homogenization maintenance of the liquid material during the waiting stage and is mechanically linked with the conveying rhythm of the solid materials. Finally, through precise extraction by the metering pump, the process goal of synchronous feeding of all three materials is achieved.

[0023] 3. This invention uses a humidity sensor to monitor ambient humidity in real time. When the humidity exceeds the standard, the heating wire is automatically activated for drying. In conjunction with the pusher plate, the material is pushed to the vicinity of the heat source for uniform heating. After drying, the tapping hammer continuously strikes and disperses the agglomerated material, forming a closed-loop process of detection, drying, pushing, and dispersing. This ensures that the material is always in a loose and conveyable state, avoiding blockage. During the drying process, the surface moisture of the material evaporates, but there may still be false agglomerates inside due to static electricity or compression. The continuous tapping of the tapping hammer can effectively disperse the agglomerated material and restore its original particle state, creating conditions for subsequent accurate metering and mixing. The lifting and lowering action of the tapping hammer is designed as an intermittent light tap to avoid continuous heavy pressure damage to the conveyor belt and extend the service life of the conveyor belt.

[0024] 4. In traditional feeding devices, the flow rate of liquid raw materials is often roughly controlled by valve opening or pump speed, which has limited accuracy. This device accurately measures the discharge of liquid raw materials through a metering pump, and can provide real-time feedback and control to ensure accurate and stable ratio of solid and liquid raw materials, thereby improving the consistency of antioxidant product quality.

[0025] 5. This invention obtains the stirring power of the premixing hopper from the driven shaft of the conveyor belt, so that it can rotate when there is material and stop when there is no material, thus avoiding energy waste and meeting the requirements of green manufacturing.

[0026] 6. In traditional separate conveying, solids and liquids enter the reactor separately and require a long time for the agitator inside the reactor to mix evenly, which prolongs the production cycle. This device premixes the materials before they enter the reactor through a premixing hopper, so that the solids and liquids are initially fused together, which greatly shortens the mixing time in the subsequent reactor and improves production efficiency.

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Example: Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6A feeding device for antioxidant production includes a feeding rack 1, a conveyor belt 2 inside the feeding rack 1, an operating frame 3 fixedly mounted on the top surface of the feeding rack 1, and a feeding assembly inside the feeding rack 1 for synchronous feeding of different antioxidant production raw materials. The feeding assembly includes a rotating shaft 4, which is movably sleeved inside the feeding rack 1. A drive shaft 5, a tensioning column 6, and a driven shaft 7 are movably sleeved inside the feeding rack 1. The conveyor belt 2 is wound around the outside of the rotating shaft 4, drive shaft 5, tensioning column 6, and driven shaft 7. A servo motor 8 is fixedly mounted on the bottom surface inside the feeding rack 1. The drive shaft of the servo motor 8 and the main... One end of the moving shaft 5 is fixedly installed with a pulley 9. A V-belt 10 is wound around the outer circular wall of the two pulleys 9. A partition plate 12 is fixedly installed on the inner top surface of the operating frame 3. An inclined block 13 is fixedly installed on one side of the partition plate 12 and one side of the inner surface of the operating frame 3. A raw material shell 11 is fixedly installed on the top surface of the operating frame 3. Heating grooves 44 are opened on both sides of the partition plate 12 and both sides of the inner surface of the operating frame 3. A heating wire 45 is fixedly installed inside the heating groove 44. A heat-conducting plate 46 is fixedly installed inside the heating groove 44. A humidity sensor 43 is fixedly installed on the top surface of the operating frame 3 and extends into the interior of the operating frame 3. Based on the above embodiments, refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 8 , Figure 10 and Figure 11 The raw material shell 11 is equipped with a stirring assembly for agitating liquid raw materials used in the production of antioxidants. The stirring assembly includes a central column 14, which is movably fitted inside the raw material shell 11. Stirring blades 15 are fixedly fitted on the outer circular wall of the central column 14. An inlet pipe 16 is fixedly installed on the top surface of the raw material shell 11 and extends into the interior of the raw material shell 11. A connecting pipe 47 is provided on the top surface of the operating frame 3. The connecting pipe 47 is fixedly installed with the raw material shell 11 and extends into the interior of the raw material shell 11. A metering pump 48 is fixedly installed on the top surface of the operating frame 3. The connecting pipe 47 is fixedly fitted with the inlet of the metering pump 48. An outlet pipe 49 is fixedly installed on the top surface of the operating frame 3 and is fixedly fitted with the outlet of the metering pump 48. A PLC controller is fixedly installed on one side of the feeding rack 1. The PLC controller is electrically connected to the servo motor 8, the metering pump 48, and the humidity sensor 43 and the heating wire 45, respectively. Due to the different types of raw materials used in antioxidant production (solid powder, granules, and liquid), the device has a partition plate 12 inside the operating frame 3. This partition plate 12 divides the internal space of the operating frame 3 into two independent areas. Correspondingly, the surface of the conveyor belt 2 is also divided into two independent spaces. Operators can place solid powder and granules into the two independent spaces on the top surface of the conveyor belt 2 respectively, achieving synchronous conveying of the two solid materials on the same conveyor belt. After the servo motor 8 starts, its drive shaft drives the pulley 9 to rotate. The two pulleys 9 achieve synchronous transmission through the V-belt 10, which in turn drives the drive shaft 5 to rotate. The rotation of the drive shaft 5 drives the conveyor belt 2 to circulate on the surfaces of the rotating shaft 4, drive shaft 5, and driven shaft 7, achieving synchronous conveying of solid powder and granules. Simultaneously, the liquid raw material is conveyed through an independent raw material shell 11. The raw material shell 11 is equipped with a central column 14 and stirring blades 15. The rotation of the central column 14 drives the stirring blades 15 to rotate, continuously stirring the liquid raw material inside the raw material shell 11 to prevent suspended matter in the liquid raw material from settling or... Emulsion stratification ensures uniform and stable composition. Traditional methods require multiple sets of equipment, such as screw conveyors, belt conveyors, and pumping systems, for solid powders, granules, and liquid raw materials. This device uses a separator plate 12 to divide the same conveyor belt into two sections, along with an independent liquid conveying channel and raw material shell 11, enabling simultaneous conveying of multiple materials from a single power source. This significantly reduces the number of equipment required. In traditional separate conveying, there is a time difference between the start and stop of each piece of equipment, resulting in inconsistent material entry into the reaction vessel and affecting the accuracy of the proportioning. This device addresses this issue through the stirring action of the stirring blades 15. The sprocket 25 and transmission components are mechanically linked with the conveyor belt 2 for solid powder and granules. When the servo motor 8 drives the conveyor belt 2, the power is transmitted to the central column 14 through the first transmission wheel 20, the first bevel gear 22, the second bevel gear 23 and the sprocket 25, so that the stirring blade 15 starts, runs and stops synchronously with the conveyor belt 2. That is, when the solid powder and granules are conveyed forward on the conveyor belt 2, the stirring blade 15 simultaneously stirs the liquid raw material in the raw material shell 11 to ensure that the liquid raw material remains in a uniform state during the conveying period. Some liquid raw materials contain undissolved solid additives or functional powders, such as anti-caking agents and stabilizers. These particles will gradually sink due to gravity when left to stand, resulting in a thinner upper liquid and particle accumulation in the lower layer. Additionally, some liquid raw materials are water-oil two-phase emulsions, which are prone to demulsification or stratification if left to stand for too long, with the upper layer being the lighter phase and the lower layer the heavier phase, leading to uneven component distribution. If the liquid raw materials are not continuously stirred and the upper or lower layer is directly drawn for feeding, the composition of the liquid raw materials entering the premixing hopper will deviate from the formulation requirements, ultimately affecting the reaction uniformity of the antioxidant and the consistency of the product. The quantitative delivery of the liquid raw materials is independently completed by metering pump 48. The inlet of metering pump 48 is connected to the outlet of raw material shell 11, and the outlet leads to the premixing hopper 50. This can be controlled simultaneously by a PLC controller. The start-up of the servo motor 8 and the metering pump 48 enables the liquid raw material conveying of the metering pump 48 to be linked with the solid powder and granular material conveying of the conveyor belt 2. The flow rate of the metering pump 48 can be set by the PLC controller to achieve synchronous start-up and stop and flow matching with the solid material conveying. When the conveyor belt 2 is running, the metering pump 48 draws out the uniformly stirred liquid raw material from the raw material shell 11 at the set flow rate and simultaneously conveys it to the premixing hopper 50. When the conveyor belt 2 stops, the metering pump 48 also stops. This device realizes the synchronous feeding of solid powder, granular material and liquid raw material: solid material is continuously conveyed on the conveyor belt 2, liquid material is continuously stirred in the raw material shell 11 and accurately drawn out by the metering pump 48, and the three are synchronously merged into the premixing hopper 50, providing a uniform and synchronous material basis for the subsequent premixing process. The core design of this device is the synchronous feeding of solid powder, granular material, and liquid raw materials. Solid materials are continuously conveyed on conveyor belt 2, and the conveying rhythm is controlled by servo motor 8. Liquid raw materials need to be drawn into the premixing hopper at a matching flow rate during the same time period of solid material conveying. When metering pump 48 is started, the first liquid drawn may be the upper clear liquid with uneven composition. As the liquid level drops, the bottom sediment is drawn out, causing the liquid composition to change over time and making it impossible to maintain the synchronous ratio stability with the solid material. Through mechanical linkage, the stirring blade 15 and conveyor belt 2 are synchronized to ensure that the liquid raw material is always in a uniform state throughout the solid material conveying process. The composition of each liquid drawn by metering pump 48 is consistent with that at startup, thus achieving true synchronous feeding, not only in time but also in composition.

[0031] Based on the above embodiments, refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 7 and Figure 10A connecting assembly for simultaneously feeding different raw materials is provided on one side of the feeding rack 1. The connecting assembly includes a fixing plate 17, which is fixedly installed on one side of the feeding rack 1. A rotating sleeve 18 is fixedly installed on the side of the feeding rack 1 near the fixing plate 17. A rotating column 19 is movably sleeved inside the rotating sleeve 18. First transmission wheels 20 are fixedly sleeved on the outer circular walls of the drive shaft 5 and the rotating column 19, respectively. A first transmission belt 21 is wound around the outer circular walls of the two first transmission wheels 20. A first bevel gear 22 is fixedly installed at the end of the rotating column 19 away from the feeding rack 1. A movable column 24 is movably sleeved inside the fixing plate 17. A second bevel gear 23 is fixedly installed at the end of the movable column 24 near the first bevel gear 22. The second bevel gear 23 meshes with the first bevel gear 22. A sprocket 25 is fixedly sleeved on the outer circular walls of the central column 14 and the movable column 24, respectively. A chain 26 meshes with the outer circular walls of the two sprockets 25. Through the sprocket 25, the drive shaft of the servo motor 8 rotates, driving the pulley 9 and V-belt 10 to rotate. The pulley 9 drives the drive shaft 5 to rotate, driving the conveyor belt 2 to move. At the same time, the rotation of the drive shaft 5 drives the first transmission wheel 20 to rotate. The two first transmission wheels 20 rotate synchronously through the first transmission belt 21. The first transmission wheel 20 drives the rotating column 19 and the first bevel gear 22 to rotate. The first bevel gear 22 meshes and drives the second bevel gear 23 to rotate. The second bevel gear 23 drives the movable column 24 and the sprocket 25 to rotate. The two sprockets 25 are connected by the chain 26 to achieve synchronous rotation. The sprocket 25 drives the central column 14 and the stirring blade 15 to rotate. Thus, the conveyor belt 2 and the stirring blade 15 achieve power linkage, start and run synchronously. Synchronous transmission ensures that solid and liquid materials start, stop and run at the same speed at the same time, avoiding material accumulation caused by the lag of one side, such as solids reaching the end but liquids not reaching, or liquids being drained but solids still being transported, ensuring accurate proportioning and smooth process connection.

[0032] Based on the above embodiments, refer to Figure 1 , Figure 2 , Figure 5 , Figure 6 and Figure 9 The external of the feeding rack 1 is fixedly installed with two support frames 27, which are symmetrically arranged. A linear motor 28 is fixedly installed on the top surface of the support frame 27. A stabilizing frame 29 is fixedly installed on the top surface of the slide table of the two linear motors 28. Two connecting rods 30 are fixedly installed on the side of the stabilizing frame 29 near the feeding rack 1. A push plate 31 is fixedly installed on the end of the connecting rod 30 away from the stabilizing frame 29. Two movable holes 32 are opened on the side of the operating frame 3 near the stabilizing frame 29. The movable holes 32 are movably connected to the connecting rods 30. The two connecting rods 30 are of different lengths. The two push plates 31 are located on both sides of the partition plate 12. The operating frame 3 is equipped with a humidity sensor 43 through the push plate 31, which is used to monitor the ambient humidity in real time. In the production process of antioxidants, solid powder and granules are usually not used as soon as they arrive, but are purchased in advance and stored in large quantities in the raw material warehouse in the form of bags or barrels. Due to the long storage period and the difficulty in accurately controlling the humidity of the warehouse environment, these materials will be continuously exposed to the air during the long-term storage. Solid powder and granules usually have a large specific surface area and a certain degree of hygroscopicity. When in contact with humid air for a long time, they will gradually absorb moisture from the environment, causing the surface of the granules to become wet and stick together. As the degree of moisture absorption increases, the originally loose powder and granules will gradually form lumps of different sizes, or even clump together. When these damp and clumped materials are taken out of the warehouse and put into production, if they are directly fed into the conveyor belt 2, the clumped materials are prone to problems such as poor flowability and poor rolling during the transportation process. At best, this will block the channel of the operating frame 3, and at worst, it will cause the conveyor belt 2 to jam and the motor to overload. More importantly, when the clumped materials enter the subsequent metering stage, the uneven volume and density changes will cause the metering pump 48 or metering equipment to be unable to accurately control the amount of feed, resulting in an inaccurate ratio of solid and liquid raw materials, which will ultimately affect the reaction efficiency of antioxidants and the consistency of product quality. To address the aforementioned issues, this device uses a humidity sensor 43 to monitor humidity changes inside the operating frame 3 in real time. When excessive humidity is detected and the material is at risk of becoming damp and clumping, the operator activates the linear motor 28. After the linear motor 28 is activated, its slide moves the stabilizing frame 29 toward the operating frame 3. The stabilizing frame 29 pushes the connecting rod 30 and the push plate 31 to move. As the push plate 31 moves inside the operating frame 3, it actively pushes the damp and clumped solid powder and granular materials closer to the heating wire 45 and the heat-conducting plate 46, bringing the material closer to the heat source, accelerating moisture evaporation, achieving rapid drying, and restoring the material to its loose state.

[0033] Based on the above embodiments, refer to Figure 1 , Figure 2 , Figure 7 , Figure 8 , Figure 10 , Figure 11 , Figure 12 and Figure 13The top surface of the operating frame 3 is provided with a beating component for breaking up agglomerated raw materials. The beating component includes a drive motor 33, which is fixedly installed on the top surface of the operating frame 3. The top surface of the operating frame 3 has two reserved openings 34. A mounting frame 35 is fixedly installed inside the reserved openings 34. A linkage rod 36 is provided between the two mounting frames 35. The linkage rod 36 movably passes through the mounting frame 35 and is fixedly installed with the drive shaft of the drive motor 33. A cam 37 is fixedly sleeved on the outer circular wall of the linkage rod 36. A support column 38 is fixedly installed inside the mounting frame 35. An L-shaped column 39 is movably sleeved on the outer circular wall of the support column 38. A force plate 40 is fixedly installed on the top surface of the L-shaped column 39. An extension rod 41 is fixedly installed on one side of the L-shaped column 39. A beating hammer 42 is fixedly installed at the end of the extension rod 41 away from the force plate 40. After the drive motor 33 starts via the set striking hammer 42, its drive shaft drives the linkage rod 36 to rotate. The linkage rod 36 drives the cam 37 to rotate. When the protruding end of the cam 37 rotates to the position of the force plate 40, it presses the force plate 40 downward. The force plate 40 drives the top of the L-shaped column 39 to move downward. The L-shaped column 39 rotates around the support column 38, and the end of it connected to the extension rod 41 and the striking hammer 42 tilts upward. The striking hammer 42 moves upward away from the surface of the conveyor belt 2. When the protruding end of the cam 37 moves away from the position of the force plate 40, the force plate 40... Released from compression, the hammer 42, under the action of gravity, drives the extension rod 41 to fall and impact the surface of the conveyor belt 2. The cam 37 continues to rotate, and the hammer 42 repeats the lifting and falling action to continuously beat the solid powder and granular materials on the conveyor belt 2, so that any lumps that may exist after drying are dispersed. During the drying process, the surface moisture of the material evaporates, but there may still be pseudo-lumps formed by static electricity or compression inside. The continuous knocking of the hammer 42 can effectively shake the lumps apart and restore their original granular state, creating conditions for subsequent accurate metering and mixing.

[0034] Based on the above embodiments, refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 8 A premixing hopper 50 is fixedly installed on the side of the feeding rack 1 away from the rotating shaft 4. A stirring column 51 is movably connected inside the premixing hopper 50. Several mixing blades 52 are fixedly installed on the outer circular wall of the stirring column 51. A second drive wheel 53 is fixedly installed on one end of the driven shaft 7 and the stirring column 51 respectively. A second drive belt 54 is wound around the outer circular wall of the two second drive wheels 53. A feeding hose 55 is fixedly installed on the side of the premixing hopper 50 away from the feeding rack 1. The feeding hose 55 extends into the interior of the premixing hopper 50. The premixing hopper 50 is located below the end of the operating frame 3. When the solid powder and granules conveyed by the conveyor belt 2 and the liquid raw materials conveyed by the raw material shell 11 arrive at the end simultaneously, they fall into the premixing hopper 50. The driven shaft 7 rotates continuously during the operation of the conveyor belt 2, driving the second drive wheel 53 to rotate. The two second drive wheels 53 are synchronously driven by the second drive belt 54, which in turn drives the stirring column 51 and the mixing blades 52 to rotate. The stirring column 51 and the mixing blades 52 react with the solid powder, granules and liquid raw materials that enter the premixing hopper 50 simultaneously. The materials are premixed. When solid powder, granular material and liquid raw materials are conveyed simultaneously, the stirring column 51 and mixing blades 52 rotate synchronously to mix. When the material is stopped from being conveyed, the stirring column 51 and mixing blades 52 automatically stop mixing. In traditional separate conveying, after the solid and liquid enter the reactor separately, the stirrer in the reactor needs to run for a long time to mix evenly, which prolongs the production cycle. This device premixes the materials before they enter the reactor through the premixing hopper 50, so that the solid and liquid are initially fused, which greatly shortens the mixing time in the subsequent reactor and improves production efficiency.

[0035] Working principle: Please refer to Figures 1-13 As shown, the partition plate 12 separates the internal space of the operating frame 3 into two independent spaces due to the different types of raw materials used in antioxidant production, namely solid powder, granules, and liquid raw materials. Therefore, the surface space of the conveyor belt 2 is also divided into two spaces. Workers can then place solid powder and granules onto the top surface of the conveyor belt 2 through these two independent spaces. The servo motor 8 drives the pulleys 9 to rotate, and the two pulleys 9 rotate synchronously via a V-belt 10. The pulley 9 then drives the drive shaft 5 to rotate, which allows the conveyor belt 2 to move on the surfaces of the rotating shaft 4, drive shaft 5, and driven shaft 7, so as to feed solid powder and granules synchronously. At the same time, the operator can put liquid raw materials into the inside of the raw material shell 11 for conveying. When the humidity in the environment is high, the solid powder and granules become damp and clump together. At this time, the operator uses the heating wire 45. The heat generated by the heating wire 45 is conducted to the heat conduction plate 46, and then the heat diffuses inside the operating frame 3, which facilitates the drying of the damp solid powder and granules.

[0036] After the worker puts the liquid raw material into the raw material shell 11 through the set stirring blades 15, the liquid raw material is temporarily stored in the shell. In order to prevent the suspended matter in the liquid raw material from settling or the emulsion from separating, and to ensure that the composition is uniform and stable, the rotating central column 14 drives the stirring blades 15 to rotate continuously, and continuously stirs the liquid raw material in the raw material shell 11.

[0037] When the drive shaft of the servo motor 8 rotates via the sprocket 25, it drives the pulley 9 and the V-belt 10 to rotate. The pulley 9 drives the drive shaft 5 to rotate, causing the conveyor belt 2 to move on the surfaces of the rotating shaft 4, the drive shaft 5, and the driven shaft 7. Simultaneously, the rotation of the drive shaft 5 drives the first transmission wheel 20 to rotate. The two first transmission wheels 20 then rotate synchronously via the first transmission belt 21. The first transmission wheel 20 then drives the rotating column 19 and the first bevel gear 22 to rotate. The rotation of the first bevel gear 22 meshes with and drives the second bevel gear 23 to rotate. The rotation of the second bevel gear 23 drives the movable column 24 and the sprocket 25 to rotate. The two sprockets 25 then rotate synchronously via the connection of the chain 26. When the sprocket 25 rotates, it drives the central column 14 and the stirring blade 15 to rotate. At this time, the rotation of the conveyor belt 2 and the stirring blade 15 starts simultaneously, allowing solid powder, granular material, and liquid raw materials to move and be fed synchronously.

[0038] When the humidity sensor 43 detects high humidity inside the operating frame 3 via the push plate 31, the operator uses the linear motor 28. After the linear motor 28 is started, its slide will drive the stabilizer 29 to move towards the position of the operating frame 3. Then the stabilizer 29 will push the connecting rod 30 and the push plate 31 to move. At this time, the push plate 31 moves inside the operating frame 3 and pushes the solid powder and granules closer to the heating wire 45 and the heat-conducting plate 46 so that the solid powder and granules can be brought closer to the heat source in a high humidity environment so that they can be dried quickly.

[0039] After the solid powder and granular materials are dried, the workers use the drive motor 33 to rotate the drive shaft of the drive motor 33, which in turn drives the linkage rod 36 to rotate. The linkage rod 36 then drives the cam 37 to rotate. When the protruding end of the cam 37 rotates to the position of the force plate 40, the cam 37 presses down on the force plate 40. This causes the force plate 40 to move the top of the L-shaped column 39 downwards. At this time, the L-shaped column 39 rotates around the support column 38. The L-shaped column 39, along with the extension rod 41 and the beater... One end of the hammer 42 will tilt upwards, and the hammer 42 will also lift upwards away from the surface of the conveyor belt 2. When the protruding part of the cam 37 moves away from the position of the force plate 40, the pressure on the force plate 40 is released, and the hammer 42 drives the natural extension rod 41 to fall. Then the hammer 42 will hit the surface of the conveyor belt 2. As the cam 37 continues to rotate, the hammer 42 will continuously rise and fall, which facilitates the beating of the dried solid powder and granules, so as to disperse the clumps of solid powder and granules.

[0040] Through the premixing hopper 50, solid powder and granules fall into the premixing hopper 50 along with liquid raw materials after passing through the inside of the operating frame 3. While the conveyor belt 2 is rotating, the drive shaft 5, the rotating shaft 4, and the driven shaft 7 will continue to rotate. When the driven shaft 7 rotates, it will drive the second drive wheel 53 to rotate. Then, the two second drive wheels 53 will rotate simultaneously through the second drive belt 54. The rotation of the second drive wheels 53 will drive the stirring column 51 and the mixing blades 52 to rotate, thereby facilitating the premixing of the solid powder, granules, and liquid raw materials that enter the premixing hopper 50 simultaneously. When the solid powder, granules, and liquid raw materials are conveyed simultaneously, the stirring column 51 and the mixing blades 52 will rotate and mix synchronously. When the solid powder, granules, and liquid raw materials stop being conveyed, the stirring column 51 and the mixing blades 52 will also stop mixing simultaneously.
