Description

Technical Field

[0001] This utility model relates to the field of polymer material processing, and in particular to an electrode strip material mixing extruder. Background Technology

[0002] With the rapid development of the new energy industry, the demand for various types of batteries is increasing day by day. The improvement of battery performance has put forward higher requirements for the performance of electrode strip materials. It is necessary to use compounding extruders to produce electrode strip materials with better performance and more stable quality. For example, lithium-ion batteries are widely used in electric vehicles, consumer electronics and other fields. In order to improve the energy density, cycle life and safety of batteries, electrode strip materials need to have good conductivity, flexibility and stability. This has prompted compounding extruders to be continuously improved and innovated to meet the needs of producing high-quality electrode strip materials. As a result, a compounding extruder for electrode strip materials has emerged.

[0003] The screw is equipped with a conveying section, a compression section, and a homogenization section. The structural differences of each section enable material processing. The conveying section uses a threaded feed to quickly deliver material. The compression section has a decreasing screw groove depth to form an extrusion and shearing field. The homogenization section uses a shallow and narrow screw groove to enhance the uniformity of the melt. During mixing, the three sections work together to generate strong shear force, breaking up the agglomeration of conductive fillers and forming a conductive network in the matrix, thereby improving conductivity and strength. Vacuum degassing ports are provided in the barrel and at the tail end to extract moisture and other substances volatilized during mixing through negative pressure, preventing air bubbles from appearing after the electrode strip is formed, avoiding breakage of conductive paths or deterioration of mechanical properties, and ensuring stable product performance.

[0004] Current electrode strip material compounding extruders have significantly promoted the optimization of industry technology and material properties, especially in achieving breakthroughs in conductive filler dispersion and extrusion precision. However, prolonged opening of the extruder nozzle can cause high-temperature materials to cool and solidify at the die, forming material deposits and clogging the flow channel, interfering with melt flow, and leading to electrode strip thickness deviations or surface defects. Repeated heating and carbonization of the deposits can also exacerbate screw and die wear, causing equipment pollution and mechanical failures, increasing the frequency of downtime maintenance, and affecting production continuity and product consistency. Therefore, an electrode strip material compounding extruder is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an electrode strip material mixing extruder, which aims to improve the problem of the extruder opening for a long time in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An electrode strip material mixing extruder includes a housing, a motor fixedly connected to one side of the housing, a mixing assembly fixedly connected to the drive end of the motor, a feeding groove inside the housing, a base fixedly connected to the side of the housing away from the motor, a limit groove and a locking groove on the inner wall of the base, a sliding column slidably connected to the inner wall of the base, a fixing block fixedly connected to one side of the sliding column, a push cover fixedly connected to one side of the fixing block, a convex plate fixedly connected to the outer wall of the sliding column, a spring sleeved on the outer wall of the sliding column, a connecting column fixedly connected to the outer wall of the sliding column, a slider movably connected to the side of the connecting column away from the sliding column, and a feeding assembly fixedly connected to one side of the housing.

[0008] As a further description of the above technical solution:

[0009] The feeding assembly includes a housing, one side of which is fixedly connected to another side of the shell. A hydraulic cylinder is rotatably connected to the inner wall of the housing. A material frame is rotatably connected to one end of the hydraulic cylinder. Two protruding pillars are fixedly connected to both sides of the material frame. Positioning grooves and guide grooves are provided on the inner walls of both sides of the housing. A connecting block is fixedly connected to one side of the housing.

[0010] As a further description of the above technical solution:

[0011] The mixing assembly includes an auger frame one, one side of which is fixedly connected to the drive end of the motor, and a mixing disc is fixedly connected to the other side of the auger frame one. A baffle is fixedly connected to the side of the mixing disc away from the auger frame one, and an auger frame two is fixedly connected to the other side of the baffle.

[0012] As a further description of the above technical solution:

[0013] One side of the spring is fixedly connected to the inner wall of the base, the other side of the spring is fixedly connected to one side of the convex plate, and the outer wall of the slider is slidably connected to the inner wall of the limiting groove.

[0014] As a further description of the above technical solution:

[0015] The outer walls of the two protruding pillars are slidably connected to the inner walls of the positioning groove and the guide groove, respectively, and the outer wall of the material frame is in contact with the inner wall of the outer shell;

[0016] As a further description of the above technical solution:

[0017] A hopper is fixedly connected to the top of the housing, and multiple liquid injection pipes are fixedly connected to the top of the housing. The side of the auger frame away from the baffle is rotatably connected to the inner wall of the housing.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, by sliding the slider along the limiting groove and the connecting column driving the sliding column, the fixed block pushes the cover away from the feeding groove. At the same time, the convex plate compresses the spring to store energy. The slider slides to the intersection of the limiting groove and the slot, rotates and presses down to embed into the slot. The gap difference between the slot and the slot triggers the spring to release energy, pushing the convex plate through the connecting column to make the slider engage the slot, ensuring that the push cover and the feeding groove are stably separated. After feeding is completed, the reverse operation makes the slider slide in the opposite direction, and the push cover resets and fits into the feeding groove. This design allows the feeding groove to be opened and closed as needed, avoiding equipment contamination caused by long-term exposure of the feeding port, reducing mechanical failures and maintenance frequency, and extending equipment life.

[0024] 2. In this utility model, when feeding material into the electrode strip material mixing extruder, after the raw material is poured into the material frame, the hydraulic cylinder is activated to push the material frame upward along the positioning groove. The protrusion cooperates with the positioning groove and the guide groove to ensure stability. After the material frame reaches the top of the positioning groove, the hydraulic cylinder makes it move in an arc with the top as the center and the distance between the positioning groove and the guide groove as the radius, until one corner of the material frame fits against the top of the connecting block and connects with the hopper. The raw material flows into the shell smoothly. This design reduces manual intervention through automated feeding, avoids feeding interruption, and improves the continuity of operation and production efficiency of the mixing extruder.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figure 1 , Figure 3 and Figure 4 This utility model provides an embodiment of an electrode strip material mixing extruder, including a housing 1. The housing 1 serves as the main body of the equipment, providing a stable installation space and operating environment for the internal components, ensuring the stable operation of the mixing extrusion. A motor 2 is fixedly connected to one side of the housing 1. The motor 2 serves as the power core, outputting a stable driving force to provide power support for the operation of the mixing components. The driving end of the motor 2 is fixedly connected to the mixing components, which mix and refine the raw materials under the drive of the motor 2. A feeding groove 6 is provided inside the housing 1. The feeding groove 6 is the output channel for the mixed material, facilitating the extrusion of the material into the housing 1. A base 7 is fixedly connected to the side of the housing 1 away from the motor 2, serving as a support and limiting function. A limiting groove 8 and a locking groove 9 are provided on the inner wall of the base 7. The limiting groove 8 and the locking groove 9 cooperate with each other. A sliding column 12 is slidably connected to the inner wall of the base 7, and the sliding column 12 can slide within the base 7.

[0033] A fixing block 15 is fixedly connected to one side of the sliding column 12, and a push cover 16 is fixedly connected to one side of the fixing block 15. The fixing block 15 drives the push cover 16 to move, controlling the opening and closing state of the feeding trough 6. A convex plate 14 is fixedly connected to the outer wall of the sliding column 12, and a spring 13 is sleeved on the outer wall of the sliding column 12. The spring 13 stores elastic potential energy when it is subjected to force, and releases it at the appropriate time to push the sliding column 12 to reset, thereby achieving stable control of the feeding trough 6. A connecting column 11 is fixedly connected to the outer wall of the sliding column 12, and a slider 10 is movably connected to the side of the connecting column 11 away from the sliding column 12. The slider 10 moves and engages in the limiting groove 8 and the slot 9 to achieve convenient control of the opening and closing state of the feeding trough 6. A feeding assembly is fixedly connected to one side of the housing 1. The feeding assembly is responsible for stably conveying the raw materials into the housing 1 to ensure that the mixing work continues.

[0034] The feeding assembly includes a housing 17, which provides an installation frame for the feeding assembly. One side of the housing 17 is fixedly connected to one side of the housing 1 to ensure a stable connection between the feeding assembly and the main equipment. A hydraulic cylinder 18 is rotatably connected to the inner wall of the housing 17. The hydraulic cylinder 18 serves as the power source for the feeding assembly. One end of the hydraulic cylinder 18 is rotatably connected to a material frame 19, which is used to load raw materials and completes the feeding process under the push of the hydraulic cylinder 18. Two protruding pillars 20 are fixedly connected to both sides of the material frame 19. Positioning grooves 21 and guide grooves 22 are provided on the inner walls of both sides of the housing 17. The positioning grooves 21 and guide grooves 22 together guide the material frame 19 to move along a predetermined trajectory to achieve stable feeding. A connecting block 23 is fixedly connected to one side of the housing 17. The cross-sectional shape of the connecting block 23 is U-shaped.

[0035] Reference Figures 2 to 4 The mixing assembly includes an auger frame 3, which rotates under the drive of motor 2, driving components such as mixing disc 4 to perform preliminary mixing and conveying of raw materials. One side of the auger frame 3 is fixedly connected to the drive end of motor 2, transmitting the power of motor 2 to other parts of the mixing assembly. The other side of the auger frame 3 is fixedly connected to the mixing disc 4, which stirs and mixes the raw materials during rotation, improving the mixing effect. The side of the mixing disc 4 away from the auger frame 3 is fixedly connected to a baffle 5, which prevents raw materials from splashing randomly during the mixing process and ensures that the mixing work is carried out in an orderly manner. The other side of the baffle 5 is fixedly connected to an auger frame 26, which works in conjunction with the auger frame 3 to further mix and convey the raw materials.

[0036] One side of the spring 13 is fixedly connected to the inner wall of the base 7, and the other side is fixedly connected to one side of the cam 14, so that the spring 13 can effectively store and release elastic potential energy under the action of the cam 14. The outer wall of the slider 10 is slidably connected to the inner wall of the limiting groove 8, ensuring that the slider 10 moves along a predetermined path and realizing the control of the feeding groove 6. The outer walls of the two protrusions 20 are respectively slidably connected to the inner walls of the positioning groove 21 and the guide groove 22, ensuring that the material frame 19 moves stably and the path is accurate. The outer wall of the material frame 19 is in contact with the inner wall of the outer shell 17, ensuring that the material frame 19 will not deviate when it moves. The top of the shell 1 is fixedly connected to the hopper 24, which receives the raw materials conveyed by the material frame 19 and guides them smoothly into the interior of the shell 1. Multiple injection pipes 25 are fixedly connected to the top of the shell 1. The injection pipes 25 can inject liquid materials into the shell 1 to meet different mixing requirements. The side of the auger frame 26 away from the baffle 5 is rotatably connected to the inner wall of the shell 1 to ensure that the auger frame 26 rotates stably and continuously participates in the mixing work. The top of the hopper 24 is fixedly connected to the bottom of the connecting block 23 so that the raw materials in the material frame 19 can smoothly enter the shell 1 through the hopper 24. The outer wall of the convex plate 14 is slidably connected to the inner wall of the base 7 to ensure that the convex plate 14 moves smoothly and cooperates with the spring 13 to realize the control of the feeding trough 6. One side of the push cover 16 is slidably connected to the inner wall of the base 7, and the other side is in contact with the outer wall of the shell 1. The opening and closing operation of the feeding trough 6 is realized by moving it.

[0037] Working principle: The motor 2 located on one side of the housing 1 is turned on, causing the driving force of the motor 2 to drive the auger frame 3, mixing disc 4, baffle 5, and auger frame 26 in a circular motion, pouring a certain amount of raw material into the material frame 19. The hydraulic cylinder 18 is then activated, pushing the material frame 19 upwards. With the cooperation of the protrusion 20, positioning groove 21, and guide groove 22, the material frame 19 is pushed by the hydraulic cylinder 18 along the path of the positioning groove 21. When it reaches the top end of the positioning groove 21, the hydraulic cylinder 18 continues to act on the material frame 19, causing the material frame 19 to move with the top end of the positioning groove 21 as the reference point. The distance between the center, positioning groove 21, and guide groove 22 forms a radius for the circular arc motion, causing one corner of the material frame 19 to fit against the top of the connecting block 23. This allows the raw material inside the material frame 19 to stably enter the interior of the shell 1 through the hopper 24, thereby significantly improving the continuity of the entire mixing extruder's operation and thus greatly increasing its operating efficiency. When the raw material inside the shell 1, after processing, needs to be extruded from the shell 1 through the feeding groove 6, the slider 10 slides along the path of the limiting groove 8. Due to the transmission of the connecting column 11, the sliding column 12 drives the cam 14 and the fixing block 15 to move with the slider 10. The movement causes the fixed block 15 to move the push cover 16, thereby separating the push cover 16 from the feeding groove 6, making the feeding groove 6 open. At the same time, the convex plate 14 compresses the spring 13, causing the spring 13 to undergo elastic deformation, generating and storing elastic potential energy. When the slider 10 slides to the intersection of the limiting groove 8 and the slot 9, the slider 10 is pushed outward and rotated at a right angle. Then it is pressed, causing the outer wall of the slider 10 to fit against the inner wall of the slot 9. The external force acting on the slider 10 is released. At this time, the distance difference created by the gap inside the slot 9 causes the elastic potential energy of the spring 13 to be released instantaneously. This causes the spring 13 to push the cam 14, which in turn moves the slide column 12. Due to the transmission of the connecting column 11, the slider 10 moves with the slide column 12, thereby achieving the effect of the slider 10 being firmly locked by the slot 9. This achieves the effect of stable separation between the push cover 16 and the feeding trough 6. When the feeding trough 6 is no longer extruding raw materials, the push cover 16 and the feeding trough 6 can be brought into contact by simply reversing the order. This allows the feeding trough 6 to be opened and closed as needed, thereby significantly reducing the frequency of mechanical failures and downtime for maintenance, and greatly extending the service life of the entire mixing extruder.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
