DETAILED DESCRIPTION
[0024] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all embodiments.
[0025] Embodiment:
[0026] Please refer to Figure 1 , Figure 2 , Figure 5 , a rubber extrusion mechanism, comprising a base frame 1 and two mounting rods 2 integrally formed on both sides of the top end of the base frame 1; a funnel bin 7 is integrally formed at one end of the top of the cylinder pipe 45, and a feeding port is provided at the top of the cylinder pipe 45; the outer end of the cylinder pipe 45 is provided with a shaping component 8; the shaping component 8 comprises a shaping head 81, an external thread 82 and an internal thread 83.
[0027] Among them, the base frame 1 is the basic support structure of the whole extrusion mechanism, which is welded by high-strength steel to ensure the stability and load-bearing capacity of the overall structure. The base frame 1 is designed as a rectangular frame, which is convenient for installation and fixation on other components.
[0028] Among them, two mounting rods 2 are respectively welded on both sides of the top end of the base frame 1, which are made of high-quality alloy steel to ensure sufficient rigidity and precision. The surface of the mounting rod 2 is precisely machined to facilitate the installation of subsequent components.
[0029] Among them, at one end of the top of the cylinder pipe 45, a feeding port of appropriate size is provided. The design of this feeding port not only ensures that the rubber can smoothly enter the inside of the cylinder pipe 45, but also avoids leakage during extrusion. The shape and size of the feeding port are customized according to the characteristics of the rubber and the extrusion requirements. The funnel bin 7 is designed as an inverted conical shape, with a larger opening at the top and gradually narrowing at the bottom to communicate with the feeding port at the top of the cylinder pipe 45. The material of the funnel bin 7 is the same as or similar to that of the cylinder pipe 45 to ensure the overall strength and corrosion resistance. The design of the funnel bin 7 helps to concentrate the addition of rubber raw materials and smoothly flow into the inside of the cylinder pipe, reducing the splashing and waste of raw materials during the addition process.
[0030] The design of the shaping component 8 allows the operator to easily replace different shaped and sized shaping heads 81 as needed, thereby meeting the diverse extrusion requirements of the rubber compound product. The shaping head 81 is the main part of the shaping component 8, with an internal thread 83 designed to match the external thread 82 of the cylinder tube 45. The outlet end of the shaping head 81 is customized according to the required shape and size of the rubber compound product, such as round, square, irregular, etc. The external thread 82 is located at the end of the cylinder tube 45, while the internal thread 83 is located on the inner wall of the shaping head 81. The two are connected by threads, achieving a tight fixation of the shaping component 8 with the cylinder tube 45. This connection not only facilitates the replacement and cleaning of the shaping component 8, but also ensures the stability and accuracy of the extrusion process. During the rubber compound extrusion process, when the shape or size of the rubber compound product needs to be changed, the operator can first unscrew the current shaping component 8, and then replace it with a shaping head 81 with the desired outlet shape. The new shaping head 81 is tightly connected with the external thread 82 of the cylinder tube 45 through its internal thread 83, ensuring the continuity and stability of the extrusion process. Subsequently, the rubber compound is extruded into the desired shape through the outlet of the shaping head 81 under the push of the rubber compound output component 4.
[0031] Please refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 , a rubber compound extrusion mechanism, two mounting rods 2 surface one end bolted with drive motor 3, and the other end is provided with rubber compound output component 4, drive motor 3 drive end and rubber compound output component 4 inner end fixed connection, rubber compound output component 4 outer wall is provided with heating component 5, and the bottom is integrally made into fixed component 6, heating component 5 electric connection through fixed component 6 inside and outside power supply, fixed component 6 bottom end two ends are respectively locked with two mounting rods 2 surface; Rubber compound output component 4 includes shaft coupling 41, rotating shaft 42, conical head 43, spiral blade 44 and cylinder tube 45; Heating component 5 includes threaded ring groove 51, heating wire ring 52, first locking head 53, second locking head 54 and two connecting wires 55; Fixed component 6 includes fixed seat 61, two grooves 62 and two groups of locking bolts 63.
[0032] Among them, the drive motor 3 selects high-performance three-phase asynchronous motor, bolted and installed on one end of the two mounting rods 2. The power and speed of the drive motor 3 are selected according to the extrusion requirements of the rubber compound, ensuring smooth and efficient extrusion process.
[0033] The mixing rubber output component 4 is designed to extrude the mixing rubber. The coupling 41 serves as a key component connecting the driving motor 3 and the rotating shaft 42, ensuring a stable and reliable connection between the two. The two ends of the coupling 41 are fixedly connected with the driving end of the driving motor 3 and one end of the rotating shaft 42, respectively, thereby achieving the transmission of driving force. The rotating shaft 42 is responsible for transmitting the rotating power of the driving motor 3 to the spiral blade 44, thereby pushing the mixing rubber to advance in the cylinder pipe 45. The other end of the rotating shaft 42 is integrally formed with a conical head 43, which helps to reduce the accumulation of materials at the outlet and improve the smoothness of extrusion. At the same time, the outer wall of the rotating shaft 42 is provided with spiral blades 44, which closely fit the inner wall of the cylinder pipe 45, ensuring uniform mixing and transmission of the mixing rubber during extrusion. The design of the conical head 43 is to optimize the extrusion effect of the mixing rubber. Its gradually narrowing outlet helps to reduce the accumulation of rubber at the outlet, improve the smoothness of extrusion, and make the extruded mixing rubber product have more uniform shape and size. The spiral blades 44 are an important part of the rotating shaft 42, which closely fit the inner wall of the cylinder pipe 45, pushing the mixing rubber from one end to the other end of the cylinder pipe 45 through rotation. The design of the spiral blades 44 not only ensures the uniform mixing and transmission of the mixing rubber, but also improves the extrusion efficiency. The cylinder pipe 45 is the main part of the mixing rubber output component 4, which provides a closed space for the transmission and extrusion of the mixing rubber. The inner wall of the cylinder pipe 45 is seamlessly fitted with one end of the outer wall of the rotating shaft 42, ensuring that the mixing rubber does not leak during extrusion. At the same time, the outer wall of the cylinder pipe 45 is provided with heating components 5 and fixing components 6, which together ensure the temperature control and stability of the mixing rubber during extrusion.
[0034] The design of the heating component 5 is responsible for the temperature of the cylinder tube 45. The thread ring groove 51 is opened on the outer wall of the cylinder tube 45, and its shape and size are designed to accommodate the heating wire ring 52. The opening position and number of the thread ring groove 51 can be customized according to the heating requirements to ensure that the rubber inside the cylinder tube 45 can be uniformly heated. The heating wire ring 52 is a resistance heating element installed inside the thread ring groove 51, which generates heat through the action of electric current to heat the cylinder tube 45 and the rubber inside it. The material and specifications of the heating wire ring 52 need to be selected according to the heating requirements and working environment. The first locking head 53 and the second locking head 54 are respectively installed at both ends of the heating wire ring 52, which are fixed on the cylinder tube 45 by fastening to ensure the stable installation of the heating wire ring 52 in the thread ring groove 51. At the same time, the first locking head 53 and the second locking head 54 also play the role of electrical connection, connecting the two ends of the heating wire ring 52 with the connecting line 55. One end of the two connecting lines 55 is respectively fixedly connected with the first locking head 53 and the second locking head 54, and the other end penetrates the side wall of the fixed component 6 and is electrically connected with the external power supply. The material of the connecting line 55 needs to have good electrical conductivity and high temperature resistance to ensure the stability and safety of the heating process. During the extrusion of the rubber, the heating component 5 starts to work. The external power supply supplies power to the heating wire ring 52 through the connecting line 55, and the heating wire ring 52 generates heat to heat the cylinder tube 45 and the rubber inside it. During the heating process, the first locking head 53 and the second locking head 54 ensure the stable installation of the heating wire ring 52 in the thread ring groove 51, avoiding its loosening or falling off due to thermal expansion. At the same time, the fixed component 6 supports and protects the heating component 5 to ensure the stability and safety of the heating process.
[0035] The design of the fixing component 6 is responsible for fixing the rubber mixing output component 4 on the two mounting rods 2; the fixing seat 61 is the main part of the fixing component 6, and its top end is integrally formed with the bottom of the cylinder pipe 45, ensuring the stable connection between the two. The design of the fixing seat 61 provides support for the cylinder pipe 45; the grooves 62 are opened at both ends of the bottom of the fixing seat 61, and their shape and size are designed for sliding connection with the outer wall of the mounting rod 2. This design allows the fixing component 6 to slide along the mounting rod 2 during installation to adjust its position, and is fixed by the locking bolt 63. The locking bolt 63 is connected in the threaded hole in the side wall of the fixing seat 61 by threads, and the inner end is fixed on the side wall of the mounting rod 2. The tightening action of the locking bolt 63 ensures the stable connection between the fixing component 6 and the mounting rod 2, preventing the fixing component 6 from moving or falling off during installation. During the installation of the cylinder pipe 45, the fixing component 6 is slid along the mounting rod 2 to the appropriate position. Then, by rotating the locking bolt 63, its inner end is fixed on the side wall of the mounting rod 2, thereby achieving a stable connection between the fixing component 6 and the mounting rod 2. This installation method not only ensures the stability and safety of the rubber mixing output component 4, but also facilitates subsequent maintenance and adjustment.
[0036] The working principle of the rubber mixing extrusion mechanism: During the rubber mixing extrusion process, the driving motor 3 serves as the power source for the entire extrusion mechanism, accurately transmitting rotational power to the rotating shaft 42 through the shaft coupling 41. This transmission process ensures the continuity and stability of the power, providing a solid foundation for subsequent rubber extrusion. Then, the helical blade 44 on the rotating shaft 42 begins to rotate at a stable speed. The design of the helical blade 44 cleverly utilizes the centrifugal force and friction of the rubber during rotation, effectively pushing the rubber in the cylinder pipe 45 from one end to the other. In this process, the rubber is not only uniformly delivered, but also further mixed and plasticized under the action of the helical blade 44, thereby improving the quality and uniformity of the product. At the same time, the heating component 5 precisely controls the heating of the cylinder pipe 45. The heating component 5 generates heat through the built-in heating wire coil 52, which is transmitted to the internal rubber through the wall of the cylinder pipe 45. As the temperature rises, the viscosity of the rubber gradually decreases, becoming more fluid and easier to extrude. This heating process not only improves the efficiency of extrusion, but also ensures the stability and controllability of the rubber during extrusion. Finally, the design of the conical head 43 further optimizes the extrusion effect. The gradually narrowing outlet of the conical head 43 helps to reduce the accumulation and blockage of rubber at the outlet, making the extruded rubber product have a more uniform shape and size. At the same time, the conical head 43 also plays a role in further compressing and plasticizing the rubber, thereby improving the density and quality of the product.
[0037] It should be noted that the specific model of the driving motor 3 and the heating wire coil 52 needs to be determined according to the actual specifications of the device, and the specific selection calculation method adopts the existing technology in the field, so it will not be described in detail.
[0038] The power supply and principle of the driving motor 3 and the heating wire coil 52 are clear to those skilled in the art, and will not be described in detail here.
[0039] It is obvious to those skilled in the art that the present application is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or essential characteristics of the present application. Therefore, the embodiments should be regarded as exemplary and non-limiting, and the scope of the present application is defined by the appended claims rather than the above description, and therefore all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present application.
