Description

Technical Field

[0001] This utility model relates to the field of conductive silicone rubber filtration and impurity removal technology, and in particular to a conductive silicone rubber filtration and impurity removal device. Background Technology

[0002] In the production process of conductive silicone rubber, impurity removal is a crucial step in ensuring product performance and stability. Traditional impurity removal methods typically employ static filtration or simple sieving. However, after prolonged use, the softened rubber becomes viscous and has poor flowability, easily accumulating and clogging on the filter screen, leading to production interruptions and requiring cleaning. Currently, the filter screens are installed inside the discharge pipe, requiring complete disassembly, which severely impacts production efficiency and is extremely inconvenient. This also creates significant difficulties for cleaning and replacing the filter screens, as well as for routine equipment maintenance, increasing maintenance costs and downtime. Therefore, a conductive silicone rubber filtration and impurity removal device is needed. Utility Model Content

[0003] Based on the existing technical problems, this utility model proposes a conductive silicone rubber filtration and impurity removal device.

[0004] The present invention proposes a conductive silicone rubber filtration and impurity removal device, including support legs, and a device base plate is installed on the top of each of the four support legs. A drive motor and a support plate are respectively installed on the top right end of the device base plate. The support plate is located at the left end of the drive motor. A spiral discharge mechanism and a filtration and impurity removal mechanism are provided on the left end of the support plate. The spiral discharge mechanism realizes the action of discharging softened rubber in a spiral shape. The filtration and impurity removal mechanism enables the filtration and impurity removal of softened rubber discharge.

[0005] Preferably, the spiral discharge mechanism includes discharge pipes, and the three discharge pipes are arranged linearly in a horizontal state. The surface of the right discharge pipe is fixedly installed with the opposite surface of the support plate. The left end surface of the support plate is also rotatably connected to a spiral shaft through a bearing. The right end of the spiral shaft passes through and extends to the right end of the support plate, and is fixedly installed with the output end of the drive motor through a coupling. A feed pipe is installed at the top of the discharge pipe at the left end of the support plate. The feed pipe is connected to the softening discharge end of the rubber softening equipment. The left end of the spiral shaft is located inside the three discharge pipes.

[0006] Preferably, a spiral blade is fixedly installed on the arc surface of the spiral shaft, and the arc surface of the spiral blade contacts the inner wall of the discharge pipe. A discharge pipe is installed on the leftmost surface of the discharge pipe, and a discharge guide pipe is installed on the inner wall of the discharge pipe. Spiral discharge grooves are opened on the inner walls of multiple discharge pipes, and the spiral discharge grooves are correspondingly arranged with the spiral blades. A guide seat is installed on the left end of the spiral shaft by screws, and the guide seat is located inside the discharge guide pipe.

[0007] Preferably, the filtration and impurity removal mechanism includes a filtration and impurity removal tube, the right end of which is connected to the left end of the discharge pipe. A clamping groove is provided on the surface of the right end of the filtration and impurity removal tube, and a filter screen is installed on the inner wall of the clamping groove.

[0008] Preferably, the opposing surfaces of each pair of discharge pipes are interlocked, and each pair of interlocking arc surfaces of the discharge pipes, the arc surfaces where the discharge pipe and the discharge pipe meet, and the arc surfaces where the discharge pipe and the filter pipe meet are all fitted with clamping components. The clamping components enable the interlocking, sealing, and locking operation of the two interlocking discharge pipes, the discharge pipe and the discharge pipe, and the discharge pipe and the filter pipe.

[0009] Preferably, the clamping assembly consists of an upper clamping ring and a lower clamping ring. The inner ring surfaces of the upper clamping ring and the lower clamping ring are both inclined. When the upper clamping ring and the lower clamping ring engage with the arc surface of the discharge pipe, the discharge pipe is clamped by pressing the inclined inner ring surfaces.

[0010] Preferably, both ends of the upper retaining ring and the lower retaining ring are provided with U-shaped grooves, and a clamping screw is sleeved on the inner wall of the U-shaped groove. The limiting bottom end of the clamping screw is located at the bottom of the lower retaining ring, and a locking screw is threaded to the top end of the clamping screw, which is located at the top of the upper retaining ring.

[0011] The beneficial effects of this utility model are as follows: First, the filtration and impurity removal function ensures that the softened rubber is effectively filtered during the discharge process, removing impurities and insoluble substances to guarantee the purity of the final discharged rubber. This not only improves the performance of the rubber but also ensures the smooth operation of subsequent processing stages.

Finally, the modular and disassembly design makes maintenance and cleaning easier. The easy-to-disassemble design allows for quick operation in case of equipment failure or when cleaning is needed, reducing downtime and improving production efficiency. Simultaneously, the design of the filter screen and clamping components results in low maintenance costs and more stable system operation. Attached Figure Description

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0015] Reference Figures 1-4 A conductive silicone rubber filtration and impurity removal device includes four support legs 1, each topped with a base plate 2. A drive motor 3 and a support plate 4 are respectively mounted on the right side of the top of the base plate 2. The support plate 4 is located to the left of the drive motor 3. A spiral discharge mechanism 5 and a filtration and impurity removal mechanism 6 are arranged on the left side of the support plate 4. The spiral discharge mechanism 5 enables the softened rubber to be discharged in a spiral shape. The spiral discharge mechanism 5 includes three discharge pipes 51, all arranged horizontally in a linear fashion. The surface of the discharge pipe 51 at the right end of the cloth is fixedly installed on the opposite surface of the support plate 4. The middle of the left end surface of the support plate 4 is also rotatably connected to the spiral shaft 52 through the bearing. The right end of the spiral shaft 52 passes through and extends to the right end of the support plate 4, and is fixedly installed to the output end of the drive motor 3 through the coupling. The top of the discharge pipe 51 at the left end of the support plate 4 is equipped with a feed pipe 53, which is connected to the softening discharge end of the rubber softening equipment. The left end of the spiral shaft 52 is located inside the three discharge pipes 51.

[0016] Specifically, the filtration and impurity removal mechanism 6 is combined with the screw discharge mechanism 5 to effectively remove impurities from the rubber, ensuring the purity of the final discharged rubber. Removing impurities through appropriate filtration ensures the stable performance of the rubber during use; the screw discharge mechanism 5 ensures that the softened rubber is discharged uniformly and continuously in a spiral shape, thereby improving discharge efficiency. The screw shaft 52 is driven by the drive motor 3, realizing an automated and stable discharge process, reducing manual intervention and improving production efficiency.

[0017] Spiral blades 54 are fixedly installed on the arc surface of the spiral shaft 52. The arc surface of the spiral blades 54 is in contact with the inner wall of the discharge pipe 51. The discharge pipe 55 is installed on the surface of the leftmost discharge pipe 51. The discharge guide pipe 56 is installed on the inner wall of the discharge pipe 55. Spiral discharge grooves 57 are opened on the inner walls of multiple discharge pipes 51. The spiral discharge grooves 57 and the spiral blades 54 are spaced at corresponding intervals. The guide seat 58 is installed on the left end of the spiral shaft 52 by screws. The guide seat 58 is located inside the discharge guide pipe 56.

[0018] Specifically, the spiral blade 54 is fixed to the arc surface of the spiral shaft 52 and contacts the inner wall of the discharge pipe 51, effectively propelling the softened rubber evenly forward along the discharge pipe 51. Through the action of the spiral blade 54, the rubber can pass through the discharge pipe 51 more smoothly, reducing friction and making the discharge more stable and efficient. The guide seat 58 is fixed to the left end of the spiral shaft 52 with screws and is located inside the discharge guide pipe 56, helping to accurately guide the flow direction of the softened rubber, reducing material stagnation in the middle of the pipe, and reducing rubber loss caused by uneven flow.

[0019] The filtration and impurity removal mechanism 6 realizes the filtration and impurity removal action in the softened rubber discharge; the filtration and impurity removal mechanism 6 includes a filtration and impurity removal pipe 61, the right end of the filtration and impurity removal pipe 61 is connected to the left end of the discharge pipe 55, the right end surface of the filtration and impurity removal pipe 61 is provided with a clamping groove 62, and a filter screen 63 is installed on the inner wall of the clamping groove 62.

[0020] Specifically, the design of the filtration and impurity removal pipe 61 and the filter screen 63 installed in the clamping groove 62 effectively remove impurities such as particulate matter, foreign objects, or insoluble substances from the softened rubber. This design helps improve the purity of the rubber, thereby ensuring the quality of the finished product and the smooth progress of subsequent processing. The filter screen 63 is fixed by the clamping groove 62, which facilitates cleaning and replacement of the filter screen 63. Regular cleaning or replacement of the filter screen 63 helps maintain the long-term efficient operation of the system and reduces maintenance costs.

[0021] The opposing surfaces of each pair of discharge pipes 51 are interlocked, and clamping components 7 are snapped onto the arc surfaces of each pair of interlocking discharge pipes 51, the arc surfaces where discharge pipe 51 and discharge pipe 55 meet, and the arc surfaces where discharge pipe 55 and filter pipe 61 meet. The clamping components 7 realize the sealing and locking operation of the two connecting discharge pipes 51, discharge pipe 55 and discharge pipe 51, and discharge pipe 55 and filter pipe 61.

[0022] Specifically, the clamping assembly 7 ensures a tight connection between all connecting parts through snap-fit ​​and sealing locking, preventing leakage of materials or liquids during transportation. The design of the clamping assembly 7 also allows for easy disassembly and replacement of each connecting component. Disassembly can be completed quickly when cleaning or maintenance is required, reducing downtime and maintenance costs, and improving production efficiency.

[0023] The clamping assembly 7 consists of an upper retaining ring 71 and a lower retaining ring 72. The inner ring surfaces of the upper retaining ring 71 and the lower retaining ring 72 are both inclined. When the upper retaining ring 71 and the lower retaining ring 72 engage with the arc surface of the discharge pipe 51, the discharge pipe 51 is clamped by pressing through the inclined inner ring surfaces.

[0024] Specifically, this is achieved through the inclined inner ring surface design of the upper retaining ring 71 and the lower retaining ring 72. When the retaining ring engages with the arc surface of the discharge pipe 51, the inclined structure generates a stronger clamping force. This squeezing action effectively enhances the sealing performance of the pipe connection, clamping the sealing rings between the connected pipes and preventing material leakage. Especially under high pressure and high flow rate conditions, it can significantly reduce the risk of leakage.

[0025] Both ends of the upper retaining ring 71 and the lower retaining ring 72 are provided with U-shaped grooves 73. The inner wall of the U-shaped groove 73 is fitted with a clamping screw 74. The limiting bottom end of the clamping screw 74 is located at the bottom of the lower retaining ring 72. The top end of the clamping screw 74 is threadedly connected with a locking screw 75, which is located at the top of the upper retaining ring 71.

[0026] Specifically, the clamping screw 74 engages with the retaining ring via a U-shaped groove 73, ensuring the upper retaining ring 71 and lower retaining ring 72 are securely fixed during assembly. The locking screw 75 further reinforces the connection via a threaded connection, ensuring the entire clamping assembly 7 will not loosen during operation, thus improving the stability and safety of the connection. The combination of the clamping screw 74 and the locking screw 75 allows for adjustment of the clamping force, enabling operators to precisely adjust the extrusion pressure according to the material, diameter, and operating conditions of the discharge pipe 51 or the unloading pipe 55. This ensures a sealed connection while preventing excessive extrusion that could deform or damage the pipe.

[0027] First, the filtration and impurity removal function ensures that the softened rubber is effectively filtered during the discharge process, removing impurities and insoluble substances to guarantee the purity of the final discharged rubber. This not only improves the performance of the rubber but also ensures the smooth operation of subsequent processing steps. The filter screen 63 is designed for more efficient impurity removal and is easy to clean and replace, maintaining the system's long-term high-efficiency operation. Second, the spiral discharge mechanism 5, through the cooperation of the spiral blades 54 and the spiral shaft 52, allows the softened rubber to be uniformly and continuously propelled along the discharge pipe 51, greatly improving discharge efficiency. This spiral discharge method not only reduces friction between the rubber and the pipe, making discharge more stable and smooth, but also improves discharge stability and automation, reducing manual intervention and lowering operational risks and human error. Furthermore, the sealing and locking clamping assembly 7, through the inclined structure of the upper and lower retaining rings 71 and 72, achieves a tight lock at the pipe connection, preventing material leakage during transportation and ensuring the safety and reliability of the entire device. The combination of clamping screw 74 and locking screw 75 allows for easy adjustment of clamping force according to different working conditions, ensuring not only a good seal but also preventing excessive compression that could deform the pipes, thus extending the equipment's lifespan. Finally, the modular and disassembly design makes maintenance and cleaning easier. The easy-to-disassemble design allows for quick operation in case of equipment failure or when cleaning is needed, reducing downtime and improving production efficiency. Meanwhile, the design of the filter screen 63 and clamping assembly 7 results in low maintenance costs and more stable system operation.

[0028] Working Principle: Drive motor 3 starts, driving the screw shaft 52 to rotate at high speed via a coupling. Softened conductive silicone rubber enters the rightmost discharge pipe 51 from the discharge end of the rubber softening equipment through the feed pipe 53. The spiral blades 54 on the screw shaft 52 are in close contact with the inner wall of the discharge pipe 51. When the screw shaft 52 rotates, the spiral blades 54 generate axial thrust on the rubber inside the pipe. This acts like a "screw pump," continuously and evenly pushing the rubber from right to left. Because the three discharge pipes 51 are linearly connected, the rubber passes through these three pipes sequentially, ensuring the continuity and stability of the conveying path. When the rubber is continuously pushed by the screw shaft 52 to the end of the leftmost discharge pipe 51, pressure is created at the connection between the discharge pipe 51 and the discharge pipe 55 due to the continuous influx of subsequent material. The pressurized rubber is pushed into the discharge pipe 55 and then into the connected filter and impurity removal pipe 61. When the rubber flows through the filter screen 63 in the clamping groove 62 at the right end of the filter and impurity removal pipe 61, solid impurities in the rubber, such as undispersed particles and foreign objects, are effectively intercepted by the filter screen 63 under pressure. The pure rubber that has passed through the filter screen 63 is then smoothly pushed by the spiral shaft 52 and guided by the guide seat 58 into the discharge guide pipe 56, and is finally discharged as a qualified product.

[0029] During equipment assembly, the operator fastens the upper retaining ring 71 and the lower retaining ring 72 to the joints of the two pipes to be connected, such as between the discharge pipe 51 and between the discharge pipe 51 and the discharge pipe 55. The clamping screw 74 is passed through the U-shaped grooves 73 of the upper and lower retaining rings 72, and then the top locking screw 75 is tightened. As the locking screw 75 is pressed down, the upper retaining ring 71 and the lower retaining ring 72 are pulled together. Because the inner surfaces of the upper and lower retaining rings 72 are inclined, this inclined structure generates a strong radially inward compressive wedge effect when they move towards the center. This force presses tightly against the joint surfaces of the two pipes, not only firmly "clamping" the pipes together, but more importantly, compressing the sealing ring between them, thereby achieving a reliable seal under high pressure and preventing leakage of the high-temperature, softened rubber during transportation.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
