Description

Technical Field

[0001] This utility model relates to the technical field of rubber mixing equipment, and in particular to a novel rubber mixing machine. Background Technology

[0002] As the most critical link in rubber production, the performance of the rubber mixing mill directly affects the uniformity and mechanical properties of the product. In the development of my country's rubber industry, the two-roll horizontal mixing structure has long held a dominant position. This structure, since its industrial application, continues to be widely used due to its simple structure and intuitive operation. However, it also suffers from the significant limitation of a single curing technology.

[0003] The existing double-roll horizontal rubber mixing mill mainly uses a pair of rollers with opposite directions and different speeds to generate shear force to complete the refining process of rubber. However, its inherent structural defects have led to prominent technical bottlenecks in multiple dimensions: First, the existing equipment is difficult to meet the requirements of precise temperature control; second, the production process relies on manual intervention, requiring operators to continuously perform manual operations such as pushing and turning materials, which not only results in low production efficiency but also poses mechanical injury safety hazards.

[0004] As my country's rubber industry transforms towards high-quality and sustainable development, especially with the urgent need for "high-quality, efficient, energy-saving, and environmentally friendly" production in the reclaimed rubber industry, the technological shortcomings of traditional two-roll horizontal mixing mills have become a key bottleneck restricting industry upgrading. How to break through the limitations of a single technological route and develop mixing equipment that combines high precision, intelligence, and stability has become a pressing technical problem to be solved in the field of rubber processing equipment. Summary of the Invention

[0005] The purpose of this utility model is to provide a novel rubber mixing machine to solve the problems mentioned in the background. To achieve this purpose, this utility model adopts the following technical solution:

[0020] A set of bearing protection baffles are installed at both ends of the roller in the radial direction and are in contact with the outer end face of the roller. They are used to prevent the rubber material from being squeezed to both sides of the roller during the pressing process, so as to prevent the rubber material from contacting the bearings connected at both ends of the roller.

[0021] A set of conveyor anti-drop baffles are connected to both sides of the extrusion plate, the two sides being the edge sides of the extrusion plate perpendicular to the conveyor belt conveying direction, used to prevent the rubber material from falling off the conveyor belt.

[0029] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0030] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0031] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0032] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0033] In the description of this embodiment, the term "multiple" means at least two.

[0034] like Figure 1 and Figure 2As shown, this embodiment provides a novel rubber mixing mill that replaces the traditional line-contact mixing mill, achieving single-roll planar mixing. This results in a large mixing contact area, high mixing efficiency, and a high rubber yield, meeting the demands of modern large-scale production and driving the industry to develop new equipment. The novel rubber mixing mill includes a frame 1, a conveying assembly 2, rollers 3, and an extrusion plate 4. The frame 1 is constructed from welded metal materials to form a frame structure, with multiple horizontal mounting surfaces on the top for mounting various functional components. The conveying assembly 2 is mounted on the frame 1. The conveying assembly 2 includes a conveyor belt 21 for carrying and conveying the rubber compound, and the conveying assembly 2 can convey the rubber compound through transmission. A roller 3 is rotatably positioned directly above the conveyor belt 21, and the rotation direction of the roller 3 is consistent with the conveying direction of the conveyor belt 21. This ensures that when the rubber particles to be processed are stably conveyed by the conveyor belt 21 to the area below the roller 3, the rotation of the roller 3 and the conveying direction of the conveyor belt 21 form a synergistic force in the same direction, preventing the rubber particles from accumulating or slipping below the roller 3. It also promotes the smooth discharge of the rubber compound from the side of the roller 3 away from the feed, effectively reducing the retention of the rubber compound in the processing area. The extrusion plate 4 is located below the upper half of the conveyor belt 21, and the top surface of the extrusion plate 4 is in contact with the lower surface of the conveyor belt 21. The part of the extrusion plate 4 near the roller 3 is set as a concave surface, and the curvature of the concave surface is consistent with the curvature of the roller 3 below. This changes the contact between the rubber material and the roller 3 from the traditional line contact to the arc surface contact, which greatly increases the contact area of ​​rubber mixing, increases the amount of rubber material processed per unit time, and improves the quality of rubber mixing, making the quality more stable. At the same time, the coordinated design of the roller 3 and the conveyor belt 21 moving in the same direction avoids the accumulation of rubber material in the processing area, ensures that the rubber material can be smoothly transported, and further improves the continuity of rubber mixing.

[0035] In this embodiment, to further illustrate the advantages of the present invention in rubber mixing efficiency, it is compared with a traditional line-contact two-roll mixing mill: the traditional line-contact two-roll mixing mill achieves rubber compounding through extrusion by two parallel rollers. Due to the limited roller structure, the contact surface between the two rollers and the rubber compound is only a narrow rectangular surface with a width of about 10 mm. In contrast, the mixing mill of the present invention adopts a 'roller 3 + concave surface of extrusion plate 4' structure. The diameter of roller 3 can be adjusted according to the rubber mixing requirements (e.g., using a roller with a diameter of 560 mm), and the width of the contact surface between the outer circumference of roller 3 and the concave surface of extrusion plate 4 increases synchronously with the increase of roller 3 diameter. In this embodiment, when a roller 3 with a diameter of 560 mm is selected, the contact surface width can reach approximately 200 mm. Based on the above difference in contact surface dimensions, under the same rubber mixing temperature (e.g., 60℃~70℃) and the same roller 3 rotation speed, the rubber mixing efficiency of the present invention (measured by the weight of rubber compound processed per unit time) can reach approximately 20 times that of a traditional line-contact two-roll mixing mill.

[0036] Specifically, in this embodiment, such as Figure 1The conveying assembly 2 includes a conveyor belt 21 and two parallel drive wheels 22 spaced apart. The axes of the two drive wheels 22 are aligned, and each drive wheel 22 is rotatably connected to the frame 1. The conveyor belt 21 surrounds the outer periphery of the two drive wheels 22, and the conveying direction of the conveyor belt 21 is perpendicular to the axes of the two drive wheels 22, thus forming a closed annular conveying structure. The conveyor belt 21 can move along an axis perpendicular to the axis of the drive wheels 22 by the rotation of at least one drive wheel 22. This embodiment, through the structural design of "dual drive wheels + annular conveyor belt", can achieve stable tension and precise guidance of the conveyor belt 21 by relying on the parallel and aligned drive wheels 22, avoiding the conveyor belt 21 from deviating or loosening during the conveying process. It can also achieve continuous cyclic conveying of the rubber material by means of the closed annular structure, greatly improving the conveying efficiency and operational stability. At the same time, it simplifies the overall structure of the transmission assembly 2 and reduces the difficulty of installation and maintenance.

[0037] In this embodiment, one or more rollers 3 are used to flexibly adapt to different rubber mixing process requirements: when a single roller 3 is used, the equipment structure is simplified and the operating energy consumption is reduced, which is suitable for preliminary calendering or small-batch processing of rubber materials; when multiple rollers 3 are used, the rubber materials can be finely processed through multiple continuous calendering passes (such as gradually adjusting the thickness and improving homogeneity), thereby improving the rubber mixing efficiency and the stability of the finished product quality, thus making the equipment more widely applicable and meeting the needs of diverse production scenarios.

[0038] like Figure 2 As shown, in this embodiment, the lowest point of the concave surface of the extrusion plate 4 is located on the radial extension line of the roller 3 (i.e., the straight line extending directly downward from the center of the roller 3 passes through the lowest point of the concave surface). This structural design ensures that the pressure of the roller 3 and the supporting force of the extrusion plate 4 on the rubber compound during the rolling process are on the same straight line, avoiding the problem of uneven rolling caused by force deviation, improving the uniformity of rubber compound rolling, and ensuring the stability of rubber compound quality.

[0039] In this embodiment, the novel rubber mixing mill also includes a rotating shaft assembly 5 and a drive assembly. The rotating shaft assembly 5 is arranged along the axial direction of the roller 3, and its radial ends are rotatably supported on the frame 1 by bearings. The middle part of the rotating shaft assembly 5 is fixedly connected to the center of the roller 3, and the radial ends of the rotating shaft assembly 5 are flush with or extend beyond the radial ends of the roller 3. The rotating shaft assembly 5 can drive the roller 3 to rotate synchronously by its own rotation. The rotating shaft assembly 5 provides stable rotational support for the roller 3, ensuring that the roller 3 remains stable even when rotating at high speed or bearing a rolling load, reducing the problem of uneven rubber thickness caused by roller 3 shaking. At the same time, the rotating shaft structure facilitates the installation and disassembly of the roller 3, reducing the difficulty of equipment maintenance. The drive assembly is connected to the rotating shaft assembly 5 and directly drives the roller 3 to rotate through the rotating shaft assembly 5. The drive assembly has high transmission efficiency and can accurately control the rotation speed of the roller 3, ensuring the matching of the rotation speed of the roller 3 with the conveyor belt 21. This design reduces power loss and improves the energy utilization efficiency of the equipment.

[0040] The new rubber mixing mill also includes a temperature control component 6, which is located on the frame 1 near the roller 3. It is used to adjust the temperature of the roller 3 so that the rubber material is always kept at a suitable temperature for rolling, thereby improving the plasticity and mixing uniformity of the rubber material.

[0041] In this embodiment, the temperature control component 6 includes a main inlet and outlet water pipe and multiple branch inlet and outlet water pipes. The main inlet and outlet water pipe is connected to the outside, and its end branches to form multiple branch inlet and outlet water pipes. One branch inlet and outlet water pipe penetrates the inside of the roller 3, while the other multiple branch inlet and outlet water pipes penetrate the inside of the extrusion plate 4. Cold water is delivered to the branch inlet and outlet water pipes through the main inlet and outlet water pipes, and the heat-exchanged hot water is collected back to the main inlet and outlet water pipes through the branch inlet and outlet water pipes and finally discharged to the outside, thereby realizing the temperature control of the roller 3 and the extrusion plate 4. This design offers multiple advantages: Firstly, the multiple sets of pipes branching from the main inlet and outlet water pipes directly penetrate the core areas of roller 3 and extrusion plate 4, allowing cold water to fully contact roller 3 and extrusion plate 4, forming efficient heat exchange. This enables precise temperature regulation of the roller 3 surface and extrusion plate 4, effectively preventing the processing quality of the rubber compound from being affected by excessively high local temperatures. Secondly, the dispersed layout of the multiple branch inlet and outlet water pipes achieves full coverage of the temperature control area, ensuring uniform temperature across all parts of roller 3 and extrusion plate 4, and eliminating interference from local temperature differences on the rubber mixing effect. Furthermore, the structure of the main inlet and outlet water pipes directly connecting to the outside facilitates the circulation operation of cold water input and hot water discharge, greatly simplifying the temperature control process. This allows for stable adaptation to the continuous temperature control requirements in continuous production scenarios, ensuring the stability and consistency of the rubber mixing process.

[0042] In this embodiment, the conveyor belt 21 is a metal conveyor belt 21, such as stainless steel or alloy material. The metal conveyor belt 21 has a hardness that matches the hardness of the roller 3, as well as higher wear resistance and ductility, and can withstand long-term rolling of the roller 3 without easily deforming, thus extending the service life of the equipment; at the same time, the metal material has better high-temperature resistance, which can be adapted to rubber mixing processes that require heat treatment, thus expanding the applicability of the equipment.

[0043] Specifically, in this embodiment, the conveyor belt 21 has a material hardness of 55~65HRC (matching the surface hardness of the roller 3), a tensile strength of not less than 500 MPa, and an elongation of not less than 20%. The metal conveyor belt 21 may be selected from one or more of the following categories: (a) stainless steel (such as 304, 316, etc.), (b) carbon steel, or (c) other alloys (such as Hastelloy, etc.), with stainless steel being preferred. The selection of materials and the design of performance parameters ensure that, on the one hand, the hardness of 55~65HRC ensures that the conveyor belt 21 is not prone to surface scratches or deformation when conveying rubber materials. Combined with a tensile strength of not less than 500 MPa, it can withstand tensile stress under long-distance conveying or heavy-load conditions, preventing the conveyor belt 21 from breaking. On the other hand, an elongation of not less than 20% gives the conveyor belt 21 a certain degree of toughness, adapting to the circular bending motion driven by the drive wheel 22, reducing bending fatigue damage. Moreover, the preferred stainless steel (such as 304, 316) has rust resistance and can adapt to harsh conveying environments such as humidity and acid and alkali, extending the service life of the metal conveyor belt 21, while reducing the frequency of maintenance and replacement under different working conditions.

[0044] In this embodiment, the width of the roller 3 along the axial direction is less than or equal to the width of the extrusion plate 4, and the width of the extrusion plate 4 is less than or equal to the width of the conveyor belt 21. This design ensures that the rubber compound does not overflow from the sides during conveying and compaction, reducing material waste. At the same time, it avoids the problem of incomplete compaction caused by width mismatch, ensuring that the edge parts of the rubber compound are also fully compacted, further guaranteeing the uniformity of the rubber compound quality.

[0045] In this embodiment, the novel rubber mixing mill also includes a baffle assembly 7, which is installed on the frame 1. The baffle assembly 7 includes a set of bearing protection baffles 71 and a set of conveyor anti-drop baffles 72. The bearing protection baffles 71 are installed at both ends of the roller 3 in the radial direction and are in contact with the outer end face of the roller 3. They are used to prevent the rubber material from being squeezed to both sides of the roller 3 during the pressing process, so as to prevent the rubber material from contacting the bearings connected at both ends of the roller 3. The conveyor anti-drop baffles 72 are connected to both sides of the extrusion plate 4. The two sides are the edge sides of the extrusion plate 4 perpendicular to the conveying direction of the conveyor belt 21. They are used to prevent the rubber material from falling off the conveyor belt 21. The design of the conveyor anti-drop baffles 72 can effectively prevent the rubber material from scattering from both sides during the conveying and crushing process, further reducing material waste and avoiding pollution of the environment around the frame 1. At the same time, the conveyor anti-drop baffles 72 form a lateral constraint on the rubber material, so that the rubber material is crushed within a limited range, avoiding uneven thickness caused by rubber material deviation and improving the stability of rubber mixing.

[0046] In this embodiment, the bearing protective baffle 71 is an engineering plastic bearing protective baffle, preferably made of nylon 6 or nylon 66. On the one hand, the bearing protective baffle 71 made of engineering plastic can suppress frictional heating and ensure stable operation of the equipment; on the other hand, it can enhance wear resistance, withstand the continuous friction caused by the rotation of the roller 3, and extend its service life.

[0047] In this embodiment, the novel rubber mixing mill also includes a scraper assembly 8, which is arranged parallel to one side of the roller 3. The scraper assembly 8 consists of a scraper seat and a scraper 81. The scraper seat is fixedly connected to the frame 1, and the scraper 81 is mounted on the scraper seat. Its scraping working surface is always in contact with the outer circumferential surface of the roller 3, and its position can be adjusted according to the wear degree of the scraper 81 to ensure that this contact state is continuously stable. The core function of this design is to effectively prevent the rubber material after rolling from sticking to the surface of the roller 3 and failing to fall off completely due to excessive temperature of the roller 3 during the rubber mixing process, thus affecting the quality of the rubber material. The position adjustment function of the scraper 81 can flexibly adapt to the wear condition of the scraper 81, and ensure the long-term stability of the contact effect through precise adjustment, thereby adapting to the continuous rubber mixing needs of different viscosity rubber materials.

[0048] In this embodiment, lifting adjustment components 9 are installed on both sides of the roller 3. The lifting adjustment components 9 are fixed on the frame 1, and the lifting adjustment components 9 can drive the roller 3 to rise and fall in the vertical direction to adjust the distance between the roller 3 and the conveyor belt 21. Specifically, the lifting and adjusting assembly 9 includes two sets of symmetrical units (corresponding to both ends of the roller 3). Each set has a fixed base 91, a driving component 92 (hydraulic cylinder / pneumatic cylinder / screw jack), and a connecting component 93. The fixed base 91 is connected to the frame 1. The driving component 92 is vertically mounted on the fixed base 91, and its output end is connected to the end of the roller 3 through the connecting component 93 (with a bearing between it and the roller 3 to ensure its rotation). When the driving component 92 is working, the two sets of units extend and retract synchronously, driving the roller 3 to rise and fall vertically to precisely adjust the distance between the roller 3 and the conveyor belt 21 and adapt to different processes. This setting is convenient for maintenance (raising the roller 3 increases the operating space, reduces difficulty, and shortens downtime), and can flexibly adjust the gap according to the rubber characteristics and process to stabilize quality. It can also comprehensively improve the rubber mixing efficiency by reducing repeated processing and ensuring production continuity.

[0049] In this embodiment, the novel rubber mixing mill also includes a PLC control component, which is mounted on the frame 1 and electrically connected to the conveying component 2, the drive component, the temperature control component 6, and the scraper component 8. By centrally controlling the conveying component 2, the drive component, the temperature control component 6, and the scraper component 8 through the PLC control component, precise and coordinated adjustment of the operating parameters of each component (such as the speed of the conveyor belt 21, the rotational speed of the roller 3, the temperature of the roller 3, and the pressure of the scraper 81) can be achieved, improving the automation level of the rubber mixing process. Simultaneously, it facilitates rapid switching of preset parameters according to the type of rubber compound, reducing human error, ensuring the consistency of rubber compound quality across different batches, and improving production efficiency.

[0050] In this embodiment, the novel rubber mixing mill also includes a lubrication component, which is installed on the frame 1 near the concave surface of the extrusion plate 4. This lubrication component continuously lubricates the contact area between the upper surface of the concave surface of the extrusion plate 4 and the lower surface of the conveyor belt 21. This arrangement effectively reduces the frictional resistance between the extrusion plate 4 and the conveyor belt 21, minimizing wear caused by long-term contact. Simultaneously, the stable lubrication ensures the smooth operation of the conveyor belt 21, preventing material conveying deviation or surface damage due to abnormal friction.

[0051] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here.
