Description

Technical Field

[0001] This utility model belongs to the field of overhead chain crosslinking extruders, and specifically relates to a flange structure for overhead chain crosslinking extruders. Background Technology

[0002] In existing catenary crosslinking extruders, flanges, as crucial components connecting the extruder body, die head, guide tube, and filter screen, do exhibit design flaws in practical applications. Specifically, after approximately 7-8 hours of operation, small bulges appear on the surface of the crosslinked wire core, and these bulges gradually enlarge as production time increases. These problems primarily stem from the following design defects in the flange structure:

[0003] 1. Unreasonable heating distribution: In the current design, dead corners or gaps are easily formed at the connection between the flange and the guide tube, especially when the quick clamp on the outer edge of the flange is narrow and there is no heating coil. This leads to uneven heat conduction, which not only affects the flowability of the material, but also easily forms local supercooled points in these areas, causing material accumulation and stagnation.

[0004] 2. The mesh area of ​​the filter plate is too large: The mesh area of ​​the filter plate in the traditional flange is large, and the feed angle is also very large (about 570°), which increases the resistance when the rubber material passes through, causing the material to be blocked and resulting in accumulation problems.

[0005] 3. Improper design of the flange and adhesive guide tube interface: The ball joint between the flange and the adhesive guide tube is difficult to align with the center during installation, which can easily lead to adhesive leakage. This design not only increases the difficulty of operation, but may also cause material leakage, pollute the working environment, and increase the waste of raw materials. Utility Model Content

[0006] In view of the above-mentioned shortcomings of the existing technology, the technical problem to be solved by this utility model is to propose a flange structure for a catenary crosslinking extruder that is simple in overall structure, convenient and quick to install, and increases the flow rate of rubber material to avoid material accumulation.

[0007] The technical solution adopted by this utility model to solve its technical problem is to propose a flange structure for a catenary crosslinking extruder, comprising: a flange and a filter plate and a guide tube connecting its two ends; wherein,

[0008] The filter plate is used to connect the extruder, and a first feed cone hole and a second feed cone hole are respectively opened in the filter plate and the flange, which are interconnected. The minor diameter of the first feed cone hole is the same as the major diameter of the second feed cone hole, and the feed angle of the first feed cone hole for the rubber material is greater than that of the second feed cone hole for the rubber material, so as to increase the flow rate of the rubber material and prevent the rubber material from being blocked and accumulating.

[0009] The outer wall of the flange connecting with the glue guide pipe is connected with a heating ring;

[0010] The end of the flange away from the filter plate is provided with a tapered pipe interface, and the glue guide pipe can adjust the coaxiality of the glue guide pipe and the second feeding tapered hole through the tapered pipe interface, so that the glue leakage is prevented when the glue guide pipe is connected with the flange.

[0011] In the flange structure for the catenary crosslinking extruder, the flange is also provided with a temperature measuring hole for installing a temperature measuring device to detect the temperature in the second feeding tapered hole.

[0012] In the flange structure for the catenary crosslinking extruder, the side wall of the filter hole on the filter plate away from the first feeding tapered hole has a surface finish of 0.8 μm.

[0013] In the flange structure for the catenary crosslinking extruder, the heating ring can be connected to the outer wall of the flange through a fastener.

[0014] In the flange structure for the catenary crosslinking extruder, the end of the glue guide pipe is also formed with a tapered connector, and the tapered connector is movably abutted against the tapered pipe interface and connected to the flange.

[0015] In the flange structure for the catenary crosslinking extruder, the glue guide pipe is also formed with a limiting block extending in the radial direction of the glue guide pipe, and the limiting block is connected with the tapered connector and used for limiting the installation position of the glue guide pipe relative to the flange.

[0016] In the flange structure for the catenary crosslinking extruder, the distance between the limiting block and the tapered connector is greater than the depth of the tapered pipe interface in the flange.

[0017] In the flange structure for the catenary crosslinking extruder, a plurality of filter holes for connecting the first feeding tapered hole and the second feeding tapered hole are formed in the filter plate.

[0018] In the flange structure for the catenary crosslinking extruder, the small diameter of the first feeding tapered hole is Φ102.

[0019] In the flange structure for the catenary crosslinking extruder, the feeding angle of the glue material in the second feeding tapered hole is 40°.

[0020] Compared with the prior art, the flange structure for the catenary crosslinking extruder has the following beneficial effects:

[0021] (1) The flange structure for the catenary crosslinking extruder effectively increases the flow rate of the rubber material, reduces the accumulation of rubber material caused by the blocking of the rubber material, and simultaneously changes the spherical interface between the flange and the rubber guide pipe into a conical interface, so that the alignment during installation is easier, and the glue leakage phenomenon is effectively prevented; in cooperation with the added heating ring, the temperature inside and outside the flange is more uniform, and the hard block phenomenon is avoided.

[0022] (2) The design of the temperature measuring hole provides great convenience for the installation of the temperature measuring device, and on the other hand, the temperature can be monitored and adjusted in real time to ensure that the rubber material is always in the best flow state, effectively reducing the production instability phenomenon caused by temperature fluctuations, helping to prolong the continuous production time and improve the production efficiency.

[0023] (3) The design of the conical connector makes the connection between the rubber guide pipe and the flange more closely and smoothly, reduces the risk of glue leakage caused by misalignment, and further ensures the accurate alignment of the two during installation by using the limiting block, improving the overall assembly precision.

[0029] The following is a specific embodiment of the present application and further describes the technical solutions of the present application in combination with the drawings, but the present application is not limited to these embodiments.

[0030] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present application are only used to explain the relative positional relationship, movement condition, etc. between the components in a certain posture (as shown in the drawings), and if the certain posture changes, the directional indications also change accordingly.

[0031] As Figures 1 to 2 shown, the flange structure 1 for the catenary crosslinking extruder 1 comprises a flange 1, a filter plate 2 connected to both ends of the flange 1, and a rubber guide pipe 3.

[0032] Specifically, the filter plate 2 is used to connect the extruder, and a first feeding taper hole 20 and a second feeding taper hole 10 are respectively formed in the filter plate 2 and the flange 1 and are communicated with each other, the small diameter of the first feeding taper hole 20 is the same as the large diameter of the second feeding taper hole 10, and the feeding angle of the first feeding taper hole 20 for the rubber material is greater than the feeding angle of the second feeding taper hole 10 for the rubber material, so as to increase the flow rate of the rubber material and prevent the rubber material from being blocked and accumulated; the outer wall of the connection between the flange 1 and the rubber guide pipe 3 is connected with a heating ring 12; the end of the flange 1 away from the filter plate 2 is provided with a tapered pipe interface 11, and the rubber guide pipe 3 can adjust the coaxiality of the rubber guide pipe 3 and the second feeding taper hole 10 through the tapered pipe interface 11, so as to prevent the rubber guide pipe 3 from leaking rubber when the rubber guide pipe 3 is connected with the flange 1.

[0033] As shown in Figures 1 to 2 , during the operation of the extruder, the rubber material first enters the first feeding taper hole 20 of the filter plate 2 (for reference to the arrow of the rubber material extrusion direction shown in Figure 1 ), and the flow rate of the rubber material is increased by the design that the small diameter of the first feeding taper hole 20 is the same as the large diameter of the second feeding taper hole 10, so as to reduce the risk of accumulation of the material at the feeding port and ensure that the material can smoothly transition from the filter plate 2 to the flange 1; because the outer wall of the connection between the flange 1 and the rubber guide pipe 3 is provided with the heating ring 12, the heating ring 12 starts to work when the equipment is running, providing uniform heat inside and outside the flange 1, preventing the material from solidifying or sticking due to local cooling, ensuring that the rubber material flows in the best state, avoiding the problems of bulging or hard block caused by uneven temperature, and improving the stability of quality and consistency of products; as for the installation of the rubber guide pipe 3 and the flange 1 in the embodiment, the end of the flange 1 away from the filter plate 2 is provided with the tapered pipe interface 11, which simplifies the connection process of the rubber guide pipe 3 and the flange 1, effectively prevents the occurrence of the rubber leakage phenomenon, and reduces the risk of material waste and environmental pollution.

[0034] The flange 1 is also provided with a temperature measuring hole 13 for installing a temperature measuring device to detect the temperature in the second feeding taper hole 10.

[0035] As shown in Figure 1As shown, in this embodiment, a temperature measuring hole 13 is provided at a specific position on the flange 1. This temperature measuring hole 13 is preferably a threaded hole. A high-precision temperature detector / sensor can be inserted through this hole to a position close to the second feed cone hole 10, ensuring good sealing between the temperature measuring device and the flange 1 to prevent material leakage or external interference from affecting the measurement results. It should be noted that the temperature measuring device continuously monitors the temperature changes within the flange 1 (second feed cone hole 10) and feeds the data back to the control system. The control system performs real-time analysis and processing based on this data to ensure that the rubber compound maintains its optimal temperature state throughout the processing. That is, when the detected temperature is lower than the set value, the control system automatically increases the power output of the heating coil 12 to raise the temperature; if the temperature is too high, the power of the heating coil 12 is reduced to prevent the material from overheating and causing deterioration or performance degradation. Real-time monitoring and temperature adjustment ensures that the rubber compound is always in an optimal flow state, effectively reducing production instability caused by temperature fluctuations, helping to extend continuous production time and improve production efficiency.

[0036] The filter plate 2 also has several filter holes 21 for connecting the first feed cone hole 20 and the second feed cone hole 10.

[0037] Furthermore, such as Figure 1 As shown, the rubber compound passing through the filter hole 21 is further conveyed to the second feed cone hole 10. Here, due to the smaller feed angle (relative to the first feed cone hole 20), the flow rate of the rubber compound increases, reducing the possibility of clogging and improving the overall flowability. The filter hole 21 is designed to remove impurities and unmelted particles from the rubber compound, ensuring that only pure rubber compound can pass smoothly and enter the second feed cone hole 10. This ensures that impurities are effectively filtered without causing excessive flow resistance, thereby guaranteeing the smooth flow of the rubber compound.

[0038] It should be noted that in the traditional flange 1 structure, the mesh area of ​​the filter plate 2 is relatively large, and the feed angle of the filter plate 2 is also relatively large. This embodiment, however, relies on reducing the feed angle, that is, reducing the angle of the second feed cone 10 from 57° to 40°. This change increases the flow rate of the rubber material when entering the second feed cone 10 and reduces the possibility of material obstruction; at the same time, the contact hole diameter of the rubber material (refer to...) Figure 1 The diameter is also changed simultaneously (from the traditional Φ126.9 to Φ102). This not only helps to increase the speed of the adhesive material passing through, but also effectively reduces the contact area between the adhesive material and the wall surface, thereby reducing the risk of material accumulation due to friction. Preferably, in this embodiment, the first feed cone hole 20 (i.e., the inner wall of Φ102) is close to the inner wall of the outermost filter hole 21 of the filter plate 2. This design helps to prevent the adhesive material from accumulating along the filter plate 2. Figure 1The arrow direction extrusion process appears to accumulate material, to ensure that the rubber can smoothly through the filter hole 21 into the second feeding cone hole 10, to ensure the smoothness and stability of the extruder operation process.

[0039] Preferably, the embodiment increases the width of the quick clamp outside the flange 1, and adjusts the width of the outer wall of the flange 1 from the traditional 34mm to 42.7mm, so as to pre-design the fixed position for installing the heating ring 12, ensure that the surface of these positions is flat, clean, without any obstacles or foreign matters, and provide a guarantee for the accuracy of the heating ring 12 aligning with the predetermined position on the outer wall of the flange 1. It should be noted that the heating ring 12 is usually designed to closely match the shape of the outer wall of the flange 1, so as to ensure that heat can be efficiently transferred to the inside of the flange 1. Fasteners such as bolts, clamps, etc. are used to firmly fix the heating ring 12 on the outer wall of the flange 1, to ensure that the fasteners are evenly distributed and exert sufficient force to make the heating ring 12 closely contact with the flange 1, reducing the energy loss in the heat conduction path and improving the heating efficiency. After mechanical fixation, electrical connection of the heating ring 12 is carried out to ensure that the power supply line is safely and reliably connected to the terminal of the heating ring 12, and necessary insulation protection measures are taken to prevent short circuit or other electrical faults.

[0040] The end of the glue guide pipe 3 is also formed with a tapered connector 30, which is movably abutted against the tapered pipe interface 11 and connected to the flange 1.

[0041] Further preferably, before installation, the tapered connector 30 of the glue guide pipe 3 and the tapered pipe interface 11 of the flange 1 are ensured to be clean and free of foreign matters. At this time, the worker can align the tapered connector 30 of the glue guide pipe 3 with the tapered pipe interface 11 on the flange 1, noting that the tapers of the two should match to ensure that they can closely match. By rotating or moving the glue guide pipe 3, the tapered connector 30 is completely matched with the tapered pipe interface 11. This design allows a certain flexibility, so that even in the case of slight misalignment, a good sealing effect can be achieved. The matching design of the two simplifies the installation steps, while providing high assembly accuracy, effectively avoiding the risk of glue leakage due to misalignment, and ensuring the safety and stability of the equipment operation.

[0042] Further preferably, as shown in Figure 1 and Figure 2 The embodiment also forms a limiting block extending in the radial direction of the glue guide pipe 3, which is connected with the tapered connector 30, and limits the position of the glue guide pipe 3 to ensure that it is closely connected with the flange 1 in sufficient space, providing convenience for quick disassembly, while also enhancing the rigidity of the overall structure and providing the reliability of the equipment.

[0043] Further preferably, as shown in Figure 2As shown, the distance between the limiting block and the conical connector 30 in the embodiment is greater than the depth of the conical pipe interface 11 in the flange 1, which ensures that the glue guide pipe 3 can be accurately positioned at the optimal position, avoiding the problems of misalignment or poor sealing caused by excessive insertion. This design improves the assembly accuracy and also ensures the overall sealing performance.

[0044] Further preferably, the side wall finish of the filter hole 21 on the filter plate 2 away from the first feeding tapered hole 20 is 0.8 μm, that is, the surface roughness of the first feeding tapered hole 20, the second feeding tapered hole 10 and the surface of the filter plate 2 close to the second feeding tapered hole 10 (in other words, the finish of the rubber contact surface) in the embodiment is adjusted from the conventional 1.6 μm to 0.8 μm, which effectively improves the machining accuracy by machining, helps to increase the flow rate of the rubber, and avoids the accumulation of rubber.
