Description

Technical Field

[0001] This invention relates to the field of wet mixing processing equipment, and more particularly to a coagulation device based on filler-latex wet mixing processing. Background Technology

[0002] Filler-latex wet compounding is an important processing method for preparing raw materials for high-performance natural rubber products. Its basic principle involves mixing fillers and latex to form a mixture, then reacting the mixture with acid to solidify it, resulting in a rubber product containing fillers. This method enables uniform dispersion of fillers within the rubber matrix, significantly improving the mechanical properties of rubber products.

[0003] In existing processing, the filler-latex mixture is typically sprayed into the acid reaction tank through a nozzle, where it rapidly solidifies upon contact with the acid. However, the solidified rubber product has a certain weight and quickly sinks to the bottom of the acid tank after molding. In continuous production, the settled rubber product tends to accumulate at the bottom, affecting the subsequent solidification reaction of the mixture. Currently, the production line mainly relies on manual periodic retrieval or removal of the accumulated rubber product from the acid tank. This method has significant drawbacks: firstly, manual material removal is inefficient and difficult to adapt to the needs of continuous production; secondly, operators are exposed to an acidic environment for extended periods, posing a safety risk of skin and respiratory burns from acidic substances.

[0004] Therefore, in order to solve the above problems, we propose a coagulation device based on filler-latex wet mixing process. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies, such as the low efficiency of relying mainly on manual periodic retrieval or discharge of accumulated rubber products from acid pools, and to propose a coagulation device based on filler-latex wet mixing process.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: Design a coagulation device based on filler-latex wet mixing process, including an acid reaction tank and a conveying mechanism installed in the acid reaction tank; Several glue spraying heads are fixedly installed on the inner side of the acid reaction tank, and a frame for supporting the end of the conveying mechanism is provided on the outer side of the acid reaction tank. The frame is equipped with an air-cooling mechanism and a reflux frame. The air-cooling mechanism is located inside the conveying mechanism, and the reflux frame is located below the conveying mechanism and connected to the acid reaction tank. A cleaning mechanism that fits into the bottom of the conveying mechanism is also installed inside the frame.

[0007] Furthermore, the air-cooling mechanism includes; A wind-cooled frame fixed within the aforementioned frame; The air-cooled frame is placed between the upper and lower layers of the annular conveyor belt of the conveying mechanism. Multiple air ducts are fixedly installed on the inner side of the air-cooled frame, and air holes are opened on the end face of the air ducts facing the upper side of the conveying mechanism.

[0008] Furthermore, the ends of the multiple air ducts are connected by a main pipe, and an air valve assembly is also provided inside the air-cooled frame.

[0009] Furthermore, the damper assembly includes; Multiple valve plates are rotatably connected to the air-cooled frame; The valve plate's shaft end extends through to the outside of the air-cooled frame and is fixedly mounted with a swing arm. A drive shaft is fixedly mounted on the outside of the middle valve plate's shaft end, and a drive rod is fixedly mounted on the outside of the drive shaft. A connecting rod is pinned between the drive rod and the swing arm.

[0010] Furthermore, a shaft is fixedly installed on the upper rotating shaft of the conveying mechanism. A first slide is slidably connected to the outer side of the shaft, and a second slide is fixedly installed thereon. An offset rod is pinned to the outer side of both the first and second slides. A counterweight is pinned between the ends of the two opposing offset rods. A compression spring is also provided between the first and second slides.

[0011] Furthermore, a transverse rod is fixedly installed on the side of the first slide block, and a toggle post is fixedly installed at the end of the transverse rod. A Z-shaped groove is provided on the outside of the drive shaft, and the toggle post slides in the Z-shaped groove.

[0012] Furthermore, a pneumatic motor is fixedly installed on the side of the air-cooled frame, and two guide rods are movably inserted into the side of the air-cooled frame. A striking block is fixedly connected between the bottoms of the two guide rods. A guide frame is fixedly installed on the upper end of the striking block, and an eccentric shaft is fixedly installed on the shaft end of the pneumatic motor. The eccentric shaft slides in the guide frame.

[0013] Furthermore, a ball valve is fixedly installed on the side of the air-cooled frame. The ball valve is connected to the pneumatic motor pipeline, and the valve stem of the ball valve is pinned to the connecting rod.

[0014] Furthermore, the cleaning mechanism includes; A mounting bracket fixed to the frame; A lifting rod is movably inserted into the fixed base, a brush plate is fixedly connected between the top ends of the lifting rod, and a spring is fixedly connected between the lifting rod and the fixed base.

[0015] Furthermore, the conveying mechanism is a Z-type conveyor.

[0016] The present invention proposes a coagulation device based on filler-latex wet mixing, which has the following advantages: The invention utilizes a conveying mechanism to achieve continuous automatic output of the coagulated product, completely solving the problem of manual material discharge. Through the conveying mechanism located in the acid reaction tank, the filler-latex mixture is sprayed from the nozzle and directly coagulated on the conveying mechanism, then continuously lifted and conveyed to the outer area of ​​the frame.

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0020] Reference Figures 1-10 In one embodiment of the present invention, a coagulation device based on filler-latex wet compounding is disclosed. Specifically, the coagulation device includes an acid reaction tank 1 and a conveying mechanism 2 installed in the acid reaction tank 1. The acid reaction tank 1 contains a reactive acid solution for rapidly coagulating the filler-latex mixture. A portion of the conveying mechanism 2 is submerged below the acid solution to receive and convey the coagulated rubber product upwards. Reference Figure 1 Several spray nozzles 3 are fixedly installed inside the acid reaction tank 1, with the outlet of each spray nozzle 3 facing the receiving section of the conveying mechanism 2. When the filler-latex mixture is sprayed out through the spray nozzles 3, it comes into contact with the acid and solidifies in a very short time, falling directly onto the conveyor belt of the conveying mechanism 2, thus avoiding the problem of solidified products directly settling and accumulating at the bottom in the traditional process. In an optional embodiment, multiple spray nozzles 3 are evenly arranged along the width of the conveying mechanism 2, and the spray angle of each spray nozzle 3 can be adjusted independently. By adjusting the spray angle of the spray nozzles 3, the mixture can fall onto the conveyor belt at different incident angles, thereby controlling the contact time and contact area between the mixture and the acid. For filler-latex mixtures with higher viscosity, a larger spray angle can be used to make the mixture spread out in a fan shape, accelerating the coagulation reaction; for mixtures with lower viscosity, a smaller spray angle can be used to concentrate the mixture and prevent splashing.

[0021] The outer side of the acid reaction tank 1 is provided with a frame 4 for supporting the end of the conveying mechanism 2. The frame 4 is used to support the output end of the conveying mechanism 2. The conveying mechanism 2 lifts the solidified product from the acid solution and transports it to the outer area where the frame 4 is located, so as to realize continuous automatic discharge. Reference Figure 2 The frame 4 is equipped with an air-cooling mechanism 5 and a return frame 6. The air-cooling mechanism 5 is located inside the conveying mechanism 2, and the return frame 6 is located below the conveying mechanism 2 and is connected to the acid reaction tank 1. A cleaning mechanism 7 is also installed inside the frame 4 and is attached to the bottom of the conveying mechanism 2.

[0022] As a further improvement, a filter screen can be installed inside the return frame 6. The dripping acid solution, after being filtered by this screen, flows back to the acid reaction tank 1, effectively trapping incompletely coagulated latex particles and filler debris, preventing impurities from returning to the acid tank and affecting subsequent coagulation reactions, while also avoiding blockage of the return pipeline. Preferably, the filter screen is detachable for easy daily cleaning and maintenance.

[0023] Specifically, the present invention employs a conveying mechanism 2, which enables continuous and automatic output of the solidified product, completely solving the problem of manual material discharge. Through the conveying mechanism 2 located in the acid reaction tank 1, the filler-latex mixture is sprayed from the spray nozzle 3 and directly solidifies on the conveying mechanism 2, then continuously lifted and conveyed to the outer area where the frame 4 is located. This eliminates the need for manual retrieval from the bottom of the tank, removing the risk of corrosion and burns from the acidic environment, while significantly improving production efficiency. Secondly, the forced air cooling of the product during the conveying process by the air cooling mechanism 5 accelerates the evaporation and dripping of acid on the product surface, reduces the product temperature, avoids adhesion or deformation caused by high temperature, and improves product quality. The air cooling mechanism 5 is located inside the conveying mechanism 2, that is, between the upper and lower layers of the conveyor belt, and can blow air upward from the inside, so that the airflow can fully penetrate the product layer, and the cooling effect is uniform and efficient.

[0024] Reference Figure 2 Preferably, in this embodiment, the conveying mechanism 2 is a Z-type conveyor with a mesh conveyor belt. The mesh structure allows acid to quickly leak from the bottom of the product during the conveying process, reducing the amount of acid carried out by the product and reducing the burden on subsequent deacidification. Secondly, the mesh provides an airflow channel for the air-cooling mechanism 5, allowing the cooling air blown out by the air duct 52 to penetrate the conveyor belt and directly act on the bottom and interior of the product, significantly improving the air-cooling efficiency. In addition, the mesh reduces the contact area between the conveyor belt and the product, reducing the product's adhesion tendency and making it easier for the product to fall off at the discharge end.

[0025] In an optional embodiment, the conveyor belt of the conveying mechanism 2 is made of acid-resistant stainless steel mesh belt or engineering plastic chain plate, with a mesh aperture of 2-8 mm and an opening ratio of 40%-60%. This aperture range ensures rapid acid leakage while providing sufficient support area for the solidified product, preventing small pieces of product from falling through the mesh. The preferred range of opening ratio balances the mechanical strength of the conveyor belt with the air-cooling penetration effect, allowing airflow to fully act on the bottom of the product while maintaining the long-term durability of the conveyor belt in acidic environments.

[0026] Reference Figure 4 In some embodiments, the air-cooling mechanism 5 of the present invention includes; The air-cooled frame 51 is fixed in the frame 4; The air-cooled frame 51 is placed between the upper and lower layers of the annular conveyor belt of the conveying mechanism 2. Multiple air ducts 52 are fixedly installed on the inner side of the air-cooled frame 51. The end face of the air duct 52 is provided with an air hole 53 facing the upper side of the conveying mechanism 2.

[0027] In this embodiment, by blowing air from inside the conveyor belt outward, the normal operation of the conveyor belt is not disturbed, and the cooling air can be applied to the solidified products carried on the conveyor belt to the maximum extent.

[0028] Multiple air ducts 52 are arranged along the conveying direction inside the air-cooled frame 51. Each air duct 52 has an air hole 53 on its end face, and the air hole 53 faces the upper side of the conveying mechanism 2, i.e., the upper layer of the conveyor belt carrying the product. When compressed air or cooling air is sent in through the air duct 52, the air hole 53 concentrates the airflow upward and sprays it through the mesh conveyor belt, directly impacting the bottom and interior of the product. Compared with the traditional method of blowing air from above or the side, this bottom-penetrating airflow can more efficiently remove residual acid and heat from the product, while using the buoyancy of the airflow to help the product remain stable on the conveyor belt, so that subsequent products can be removed from the conveyor belt.

[0029] In other words, this embodiment achieves efficient and uniform penetrating air cooling of the solidified product by embedding the air-cooled frame 51 between the upper and lower layers of the conveyor belt and adopting the structure of the air duct 52 and air hole 53 facing the upper side of the conveyor belt, which significantly improves the deacidification efficiency and product shaping quality.

[0030] Reference Figure 4 Based on the above embodiments, in this embodiment, the ends of multiple air ducts 52 are connected together by a main pipe 54, and an air valve assembly 55 is also provided inside the air-cooled frame 51. Of course, in this embodiment, the main pipe 54 should be connected to an external positive pressure device. This method is a conventional method for those skilled in the art and will not be elaborated here.

[0031] In an optional embodiment, the bottom of the air-cooled frame 51 is provided with a drainage hole or is directly hollowed out. Since some acid mist will condense and accumulate on the inner wall of the air-cooled frame 51 during the air-cooling process, or water will be left behind when cleaning the equipment, the drainage hole can allow the accumulated liquid to be discharged in time, avoiding long-term immersion and corrosion of the air-cooled frame 51 and the air duct 52 by acid. A drip tray can be installed below the drainage hole and led to the return frame 6 to prevent acid from dripping onto the ground and causing pollution.

[0032] Reference Figure 5 , Figure 7 In an optional embodiment, the damper assembly 55 of the present invention includes; Multiple valve plates 551 are rotatably connected in the air-cooled frame 51; The valve plate 551 has its shaft end extending to the outside of the air-cooled frame 51 and is fixedly mounted with a swing rod 552. A drive shaft 553 is fixedly mounted on the outside of the shaft end of the middle valve plate 551. A drive rod 554 is fixedly mounted on the outside of the drive shaft 553. A connecting rod 555 is pinned between the drive rod 554 and the swing rod 552.

[0033] Through the above structure, multiple valve plates 551 can adjust the air outlet cross-sectional area of ​​the air duct 52. In specific operation, when the drive shaft 553 is driven to rotate by external force, the drive rod 554 swings accordingly, and through the connecting rod 555, it drives all the swing rods 552 to rotate synchronously, so that each valve plate 551 opens and closes in linkage.

[0034] Setting the drive shaft 553 at the shaft end of the central valve plate 551 facilitates the symmetrical transmission of force, ensuring that the force on both sides of the swing rod 552 is evenly distributed, and reducing the torsional deformation of the connecting rod 555. The connecting rod 555 is connected to the swing rod 552 and the drive rod 554 by a pin connection. This air valve assembly 55 realizes centralized linkage control of the air volume of multiple air ducts 52. Only one rotational driving force needs to be applied to the drive shaft 553 to synchronously adjust the opening of all valve plates 551.

[0035] Reference Figure 8 , Figure 9 In some embodiments, a shaft 21 is fixedly installed on the upper rotating shaft of the conveying mechanism 2 of the present invention. A first slide block 22 is slidably connected to the outer side of the shaft block 21, and a second slide block 23 is fixedly installed thereon. An offset rod 24 is pinned to the outer side of both the first slide block 22 and the second slide block 23. A counterweight block 25 is pinned between the ends of the two opposing offset rods 24. A compression spring 26 is also provided between the first slide block 22 and the second slide block 23.

[0036] Specifically, when the drive shaft of the conveying mechanism 2 rotates, the shaft 21 rotates accordingly, and the counterweight 25 is thrown outward by centrifugal force. The force of the throw pulls the first slide 22 through the offset rod 24, causing the first slide 22 to slide along the shaft 21 towards the second slide 23, while compressing the compression spring 26. At this time, the faster the conveying speed, the more the counterweight 25 is thrown outward, and the greater the distance the first slide 22 moves. When the conveying speed slows down, the centrifugal force decreases, and the compressed spring 26 pushes the first slide 22 back. Thus, the level of the conveying speed becomes the back-and-forth movement of the position of the first slide 22, which facilitates subsequent control.

[0037] In an optional embodiment, the mass of the counterweight 25 can be selected according to the normal operating speed range of the conveying mechanism 2. For applications with higher conveying speeds, a smaller counterweight 25 can be used to make changes in centrifugal force more sensitive; for applications with lower conveying speeds, a larger counterweight 25 can be used to ensure that sufficient centrifugal force can still be generated to drive the first slide 22 to move at low speeds. By selecting the mass of the counterweight 25, the response range of the centrifugal sensing mechanism can be matched with the actual operating speed of the conveying mechanism to adapt to different working conditions.

[0038] Reference Figure 8 Based on the above embodiments, in this invention, a transverse rod 27 is fixedly installed on the side of the first slide block 22, and a toggle post 28 is fixedly installed at the end of the transverse rod 27. A Z-shaped groove 29 is provided on the outside of the drive shaft 553, and the toggle post 28 slides in the Z-shaped groove 29.

[0039] In other words, in this invention, when the first slide block 22 moves axially along the shaft 21, the transverse rod 27 drives the actuating column 28 to move synchronously. The actuating column 28 slides in the Z-shaped groove 29, and the linear motion is converted into the rotational motion of the drive shaft 553 by the inclined guide effect of the Z-shaped groove. Specifically, as the conveying speed of the conveying mechanism 2 increases, the distance that the first slide block 22 moves towards the second slide block 23 increases, and the angle through which the actuating column 28 pushes the drive shaft 553 to rotate in the Z-shaped groove 29 increases accordingly, thereby increasing the opening of the valve plate 551 of the air valve assembly 55 and increasing the air volume of the air duct 52; conversely, when the conveying speed decreases, the first slide block 22 retracts under the action of the compression spring 26, the actuating column 28 moves in the opposite direction, the drive shaft 553 rotates in the opposite direction, the opening of the valve plate 551 decreases, and the air volume decreases.

[0040] The design of this structure aims to make the air volume change in the same direction as the conveying speed: when the speed is high, the product residence time is short and the output is large, requiring a large air volume for rapid cooling and deacidification; when the speed is slow, the product residence time is long and the output is small, and a small air volume can meet the process requirements, thereby avoiding energy waste and excessive cooling.

[0041] Reference Figure 7 In an optional embodiment, a pneumatic motor 56 is fixedly installed on the side of the air-cooled frame 51 of the present invention, and two guide rods 57 are movably inserted into the side of the air-cooled frame 51. A striking block 58 is fixedly connected between the bottoms of the two guide rods 57. A guide frame 59 is fixedly installed on the upper end of the striking block 58, and an eccentric shaft 561 is fixedly installed on the shaft end of the pneumatic motor 56. The eccentric shaft 561 slides in the guide frame 59.

[0042] In an optional embodiment, the striking block 58 is made of a metal block coated with nylon or polyurethane. The outer elastic material can buffer the impact force when striking the conveyor belt, avoiding mechanical damage to the conveyor belt and reducing striking noise. The inner metal block ensures sufficient mass to produce an effective shaking effect.

[0043] In addition, a muffler may be installed on the exhaust pipe of the pneumatic motor 56. The pneumatic motor 56 produces significant exhaust noise when operating at high speeds; the muffler can significantly reduce this noise and improve the noise level of the working environment. The muffler is preferably made of polytetrafluoroethylene (PTFE) or stainless steel to resist corrosion from acidic mists and to facilitate regular disassembly and cleaning of accumulated impurities.

[0044] When the pneumatic motor 56 operates, the eccentric shaft 561 rotates eccentrically and slides back and forth within the guide frame 59, thereby driving the guide frame 59 and the striking block 58 fixed thereto to move up and down reciprocally. The striking block 58 periodically strikes the bottom surface of the conveyor belt of the conveyor mechanism 2. The guide rod 57 is slidably inserted into the side of the air-cooled frame 51 to guide the striking block 58 and ensure its vertical lifting. Through this striking mechanism, acid and small particle residues adhering to the mesh and surface of the conveyor belt can be shaken off, preventing mesh blockage, while accelerating the separation of acid at the bottom of the product and improving the deacidification effect. The striking frequency is determined by the rotational speed of the pneumatic motor 56.

[0045] Specifically, in this embodiment, a ball valve 510 is also fixedly installed on the side of the air-cooled frame 51. The ball valve 510 is connected to the pneumatic motor 56 pipeline, and the valve stem of the ball valve 510 is pin-connected to the connecting rod 555.

[0046] Link 555 in the air valve assembly 55 is used to synchronize the movement of each swing rod 552, and its swing angle corresponds to the opening of the valve plate 551. Since the valve stem of the ball valve 510 is pin-connected to the link 555, when the conveying speed changes and causes the link 555 to swing, the valve stem of the ball valve 510 rotates accordingly, thereby adjusting the opening of the ball valve 510 and controlling the flow of compressed air into the pneumatic motor 56. The faster the conveying speed, the larger the opening of the valve plate 551, the larger the swing angle of the link 555, the larger the opening of the ball valve 510, the greater the air intake volume of the pneumatic motor 56, the higher its speed, and the faster the knocking frequency; conversely, when the conveying speed decreases, the opening of the ball valve 510 decreases, and the knocking frequency decreases. Thus, the linkage control of airflow regulation and knocking frequency regulation is realized simultaneously through a single link 555, so that both change in the same direction with the conveying speed, resulting in a simple structure.

[0047] In other words, this invention achieves synchronous control of airflow adjustment and tapping frequency adjustment, both of which change in the same direction as the conveying speed of the conveying mechanism 2. Specifically: when the conveying speed increases, the rotational speed of the shaft 21 increases, the centrifugal force of the counterweight 25 increases, pulling the first slide block 22 to slide towards the second slide block 23, and the transverse rod 27 and the actuating column 28 move accordingly. The actuating column 28 pushes the drive shaft 553 to rotate in the Z-shaped groove 29. The drive shaft 553 drives each swing rod 552 to rotate through the drive rod 554 and the connecting rod 555, thereby increasing the opening of the valve plate 551 and increasing the airflow of the air duct 52, thus achieving enhanced cooling and deacidification of the products on the conveyor belt. At the same time, the swing of the connecting rod 555 drives the valve stem of the ball valve 510 pinned to it to rotate, which increases the opening of the ball valve 510, increases the flow of compressed air into the pneumatic motor 56, and increases the speed of the pneumatic motor 56. Through the cooperation of the eccentric shaft 561 and the guide frame 59, the striking block 58 is driven to move up and down reciprocally, and the striking frequency increases accordingly, shaking off the product and acid and residue in the conveyor belt mesh.

[0048] Conversely, when the conveying speed decreases, the centrifugal force decreases, the compression spring 26 pushes the first slide 22 to reset, the valve plate 551 opening decreases, the air volume decreases, and at the same time, the ball valve 510 opening decreases, the pneumatic motor 56 speed decreases, and the knocking frequency decreases. This linkage control is achieved entirely through mechanical transmission, without any sensors or electronic control components, allowing the air volume and knocking intensity to automatically adapt to the production line speed. This ensures that the product is fully cooled and deacidified at high speeds and that the mesh is not clogged, while avoiding energy waste and excessive impact at low speeds.

[0049] Reference Figure 10 In an optional embodiment, the cleaning mechanism 7 of the present invention includes; The fixing seat 71 is fixed to the frame 4; A lifting rod 72 is movably inserted into the fixed base 71, and a brush plate 73 is fixedly connected between the top ends of the lifting rod 72. A spring 74 is fixedly connected between the lifting rod 72 and the fixed base 71.

[0050] Under the elastic force of the spring 74, the brush plate 73 maintains elastic contact with the bottom surface of the conveyor belt, continuously scraping away residue as the conveyor belt operates. The sliding fit between the lifting rod 72 and the fixed seat 71 ensures that the height of the brush plate 73 can automatically adjust with the movement of the conveyor belt, and the spring 74 provides constant contact pressure, which ensures both cleaning effect and avoids excessive wear on the conveyor belt caused by rigid contact.

[0051] In an optional embodiment, the bottom of the frame 4 is provided with height-adjustable foot supports. By adjusting the height of the foot supports, the entire frame 4, along with the discharge end of the conveying mechanism 2, the air-cooling mechanism 5, and the cleaning mechanism 7 mounted on it, can be kept horizontal or have an appropriate tilt angle, making it easy to adapt to different site foundation conditions. Rubber vibration damping pads can be installed at the bottom of the foot supports to further absorb the vibrations generated during equipment operation and reduce the impact on the ground.

[0052] When this device is in operation, the reaction acid is first injected into the acid reaction tank 1 to the predetermined level, the conveying mechanism 2 is started and its conveying speed is set according to the production process requirements. The drive shaft of the conveying mechanism 2 drives the Z-shaped mesh conveyor belt to run continuously, while an external compressed air source supplies air to the air duct 52 and pneumatic motor 56 of the air-cooling mechanism 5.

[0053] The filler-latex mixture is continuously sprayed from several spray nozzles 3 onto the receiving section of the conveyor belt of the conveying mechanism 2, which is submerged below the acid solution surface. Upon contact with the acid solution, the mixture rapidly coagulates, forming a rubber product containing the filler that adheres to the surface of the conveyor belt. Due to the mesh structure of the conveyor belt, the acid solution can leak through the mesh, while the coagulated product is lifted upwards by the conveyor belt and carried away from the acid solution surface.

[0054] When the conveyor belt carries the product into the air-cooling area, the air duct 52 in the air-cooling frame 51 sprays cooling air upward through the air hole 53. The airflow penetrates the mesh conveyor belt and acts directly on the bottom and inside of the product, accelerating the evaporation and dripping of residual acid on the product surface, while reducing the product temperature and allowing it to quickly set. The airflow is controlled by the opening of the valve plate 551 of the air valve assembly 55, which is automatically adjusted according to the conveying speed via a mechanical linkage mechanism: the drive shaft drives the shaft 21 to rotate, and the counterweight 25 is thrown outward under the action of centrifugal force, pulling the first slide 22 against the elastic force of the compression spring 26 towards the second slide 23 via the offset rod 24; the faster the conveying speed, the greater the moving distance of the first slide 22, and the transverse rod 27 and the actuating column 28 fixed on it move synchronously. The actuating column 28 slides in the Z-shaped groove 29 of the drive shaft 553, converting linear motion into rotational motion, causing the drive shaft 553 to rotate, which in turn drives each swing rod 552 and the valve plate 551 to rotate synchronously via the drive rod 554 and the connecting rod 555, increasing the opening of the valve plate 551 and increasing the airflow. Conversely, when the conveying speed slows down, the centrifugal force decreases, the compression spring 26 pushes the first slide 22 to reset, the opening of the valve plate 551 decreases, and the airflow decreases. This achieves mechanical linkage between air volume and conveying speed, ensuring that a large air volume is obtained for rapid cooling when the product residence time is short, and automatically reducing the air volume to avoid waste when the residence time is long.

[0055] Simultaneously, the oscillation of connecting rod 555 also drives the valve stem of ball valve 510, which is pinned to it, to rotate, adjusting the opening of ball valve 510 and controlling the flow of compressed air into pneumatic motor 56. The faster the conveying speed, the larger the opening of ball valve 510, and the higher the speed of pneumatic motor 56. The eccentric shaft 561, fixed to its shaft end, rotates eccentrically within guide frame 59, driving striking block 58 to reciprocate up and down along guide rod 57, increasing the striking frequency, and periodically striking the bottom surface of the conveyor belt, shaking off acid and fine particles adhering to the mesh and the bottom of the product. When the conveying speed slows down, the striking frequency automatically decreases.

[0056] The dripping acid and the liquid shaken off by the impact fall into the return frame 6, where solid impurities are intercepted by the filter screen and then returned to the acid reaction tank 1 for recycling. As the conveyor belt continues to run to the discharge end, the dried rubber product falls off by gravity into the receiving hopper to complete the discharge. During the return journey of the conveyor belt, the brush plate 73 of the cleaning mechanism 7 maintains elastic contact with the bottom surface of the conveyor belt under the action of the spring 74, continuously scraping away residues and preventing the mesh from clogging.

[0057] The entire production process requires no manual intervention. Once the conveying speed is set, the air volume and tapping frequency are automatically matched, realizing continuous, stable, safe and automated operation of filler-latex wet mixing.

[0058] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
