Description

Technical Field

[0001] This invention relates to the field of cable sheath extrusion equipment technology, and in particular to a torque-optimized twin-screw grouting extruder and its control system. Background Technology

[0002] Cables, as key components for power transmission and signal transmission, occupy a crucial position in modern society's infrastructure. In traditional cable manufacturing processes, the screw extruder is the core equipment, and its performance directly affects the cable's forming quality, production efficiency, and energy consumption. However, existing screw extruders generally suffer from high energy consumption, uneven material mixing, and low temperature control precision, which limit the improvement of cable product quality and further increases in production efficiency.

[0003] Especially on high-speed production lines, the lack of effective torque monitoring and dynamic adjustment mechanisms leads to large fluctuations in motor load, which not only increases energy consumption but may also trigger a series of chain reactions such as accelerated equipment wear and increased maintenance costs. Therefore, developing a screw extruder and its control system capable of real-time torque optimization and control is of great significance for improving the technological level and market competitiveness of the cable manufacturing industry.

[0004] Chinese Patent CN210940369U discloses a twin-screw extruder for producing PVC cable sheath material, including a gearbox, a power distribution box, and a worktable. The gearbox includes a feed hopper, a control panel, a barrel, a die head, a support frame, a geared motor, an infrared detector, a rotating plate, and a screw. The power distribution box includes a movable door, a drive motor, wires, a reserve battery, and an insulating inner wall. An infrared detector and a feeder are installed inside the gearbox. Before each operation, the infrared detector automatically checks for abnormalities in the parts inside the device, replacing early manual inspection, saving time, and reducing the error rate. Secondly, the feeder can adjust the feeding speed to avoid material accumulation in the barrel and damage to the device. A reserve battery is installed in the power distribution box. When there is a power outage, the reserve battery starts to supply power, which will not affect the work process and improves work efficiency.

[0005] However, the sheath thickness in the above technical solutions cannot be automatically adjusted according to the cable diameter, requiring manual adjustment, which is complicated and delays production. At the same time, the torque of the twin screw cannot be optimized according to the extrusion speed, making it difficult to maintain a stable output rate. The feeding speed cannot be automatically matched with the cable blank feeding speed, resulting in uneven or poor continuity of the extruded sheath thickness, low level of production intelligence, and low production efficiency. Summary of the Invention

[0006] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the invention.

[0033] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0034] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0035] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0036] Example 1

[0037] Reference Figures 1-8 This is the first embodiment of the present invention. This embodiment provides a torque-optimized twin-screw grouting extruder, including an extrusion assembly, a coating assembly and a detection assembly. The extrusion rate of the extrusion assembly is adjusted according to the feeding speed of the cable blank 202 to ensure the sheath thickness and continuity, ensure the processing accuracy of the cable, reduce processing errors, and automatically identify cable blanks 202 of different specifications and thicknesses to match the corresponding sheath thickness.

[0038] Specifically, a torque-optimized twin-screw slurry extruder includes:

[0039] The extrusion assembly includes a support platform 100, a drive motor 101 on the support platform 100, a transmission screw 102 at the output end of the drive motor 101, a hollow cylinder 103 on the support platform 100, and two transmission screws 102.

[0040] The encapsulation assembly includes a sheath shell 200 located at the end of the hollow cylinder 103, a conical block 201 slidably disposed inside the sheath shell 200, a cable blank 202 slidably disposed inside the conical block 201, and the cable blank 202 being pulled by an external force to slide and feed along the axis of the conical block 201.

[0041] The detection assembly includes rollers 300 that are attached to the surface of the cable blank 202. When the rollers 300 rotate, they measure the feeding speed of the cable blank 202. There are at least two rollers 300. When the outer diameter of the cable blank 202 changes, the rollers 300 are driven to roll and rise, thereby driving the conical block 201 to move.

[0042] The sheath 200 has a conical cavity 2001 inside, the end of the hollow cylinder 103 is perpendicularly connected to the axis of the conical cavity 2001, and the hollow cylinder 103 is also provided with a feed inlet 2002.

[0043] The raw materials required for the cable sheath enter the hollow cylinder 103 through the feed inlet 2002. Two transmission screws 102 are arranged in parallel inside the hollow cylinder 103. The transmission screws 102 include crushing tooth sections and mixing tooth sections, which are used to crush and mix the sheath raw materials and continuously convey them forward. A heating ring is provided on the outer sleeve of the hollow cylinder 103 to heat and melt the sheath raw materials.

[0044] More preferably, the conical cavity in the conical cavity 2001 is perpendicularly connected to the cylindrical cavity in the hollow cylinder 103. As the conical block 201 slides in the conical cavity 2001 in a direction away from the outlet of the conical cavity 2001, the communication area between the hollow cylinder 103 and the conical cavity 2001 increases, thereby increasing the rate at which the molten sheathing material enters the sheath shell 200.

[0045] Preferably, the conical cavity 2001 and the end of the conical block 201 are conically engaged. As the conical block 201 moves away from the outlet position of the conical cavity 2001, the annular gap between them increases uniformly, thereby increasing the thickness of the extruded sheath. The cable blanks 202 of different specifications and thicknesses are automatically identified and matched with the corresponding sheath thickness.

[0046] More preferably, while the cable blank 202 is being slidably fed, the feeding speed of the cable blank 202 is measured by the fitted roller 300 and the data is recorded. The drive motor 101 optimizes the torque according to the feeding speed of the cable blank 202, so that the extrusion rate of the extrusion assembly matches the feeding speed of the cable blank 202. As the feeding speed of the cable blank 202 changes, the extrusion rate automatically adjusts with the torque, reducing the unevenness of the sheath thickness, ensuring the processing accuracy of the cable, and reducing processing errors.

[0047] Example 2

[0048] Reference Figures 1-8 This is the second embodiment of the present invention. This embodiment is based on the previous embodiment, but the difference is that the gap between the conical block 201 and the conical cavity 2001 is changed by moving the roller 300, thereby changing the thickness of the extruded sheath and adapting it to cable blanks 202 of different diameters.

[0049] Specifically, the sheath 200 is provided with a base 1001, a lifting rod 1002 is slidably provided on the base 1001, a ramp 1003 is provided on the end face of the lifting rod 1002, and a support arm 1004 is rotatably provided on the base 1001.

[0050] Among them, the lifting rod 1002 is provided with rollers 300 at one end near the cable blank 202 and at both ends of the support arm 1004. The roller 300 at the end near the cable blank 202 rolls and fits against the surface of the cable blank 202, and its axis is perpendicular to the axis of the conical cavity 2001.

[0051] More preferably, the roller 300 at the other end of the support arm 1004 is arranged parallel to the axis of the cable blank 202, and it is rolled and attached to the surface of the slope 1003. In this embodiment, the slope 1003 is a right triangle attached to the lifting rod 1002, and the end of the right angle is far away from the cable blank 202.

[0052] Among them, the support arm 1004 is a broken bar with an obtuse angle opening. The opening of the support arm 1004 is close to the cable blank 202. The three rollers 300 close to the cable blank 202 are arranged in a circumferential array on the surface of the cable blank 202. There are two bases 1001, which are spaced apart on the outer wall of the cable blank 202.

[0053] Preferably, a rack 1005 is slidably provided on the sheath 200, a gear 1006 is meshed on the rack 1005, an adjusting shaft 1007 is coaxially provided on one end face of the gear 1006, and a universal joint 1018 is provided at the end of the adjusting shaft 1007.

[0054] Among them, the end of the lifting rod 1002 away from the cable blank 202 is connected in parallel with the rack 1005 and slides synchronously, and the two racks 1005 are arranged in parallel to each other.

[0055] Furthermore, the universal joint 1018 is provided with a groove 1008 at the end away from the adjustment shaft 1007, and a slider 1009 is slidably provided in the groove 1008, with a slider rod 1011 on the slider 1009.

[0056] Among them, the slide rod 1011 slides through the slide groove 1008 and is provided with a first elastic element 1012 at one end. The slider 1009 is provided with a turntable 1013. The turntable 1013 is rotatably provided with a clamp 1014. The inner wall of the clamp 1014 is slidably fitted with a driven block 1015. A connecting plate 1016 is provided between the driven block 1015 and the conical block 201.

[0057] More preferably, in this embodiment, the driven block 1015 is a square block, the inner wall of the clamp 1014 is a waist-shaped groove, the driven block 1015 is fitted into the inner wall of the clamp 1014 and slides along it, and the connecting plate 1016 slides in the sheath shell 200 along the axial direction of the cable blank 202.

[0058] In summary, when the diameter of the incoming cable blank 202 changes, it simultaneously pushes the rollers 300 on the two bases 1001 to move outward. At the same time, all three rollers 300 clamp the outer wall. When the speed sensor detects that the rotation speed of each roller 300 changes in a step-like manner, it determines that a change in diameter has occurred. The lifting rod 1002 moves downward and simultaneously drives the support arm 1004 to swing through the slide 1003. Each roller 300 continues to clamp the cable blank 202 simultaneously to prevent the cable blank 202 from swaying or becoming misaligned.

[0059] Meanwhile, as the diameter increases, the lifting rods 1002 move away from each other, causing the two racks 1005 to move away from each other. As a result, the gear 1006 rotates and drives the turntable 1013 to rotate through the universal joint 1018. The clamp 1014 on the turntable 1013 moves accordingly, causing the driven block 1015 to move towards the cable inlet of the sheath shell 200. This increases the gap between the conical block 201 and the conical cavity 2001, increasing the thickness of the extruded sheath and adapting to cable blanks 202 of different diameters.

[0060] Example 3

[0061] Reference Figures 1-8 This is the third embodiment of the present invention. This embodiment is based on the previous embodiment, but the difference is that the gear 1006 can move up and down. When a fault or defect occurs in the cable blank 202, the conical block 201 and the conical cavity 2001 are automatically closed to prevent the sheath from continuing to be produced. This realizes automatic detection and alarm of defects, reduces product defects, and improves the quality of cable production.

[0062] Specifically, a buffer groove 3001 is provided on the sheath shell 200, and a buffer block 3002 is slidably provided in the buffer groove 3001. The adjusting shaft 1007 rotates through the buffer block 3002, and a second elastic element 3003 is provided between the buffer block 3002 and the inner wall of the buffer groove 3001.

[0063] Among them, the second elastic element 3003 is a spring and two are symmetrically arranged, so that the buffer block 3002 is always located in the center of the buffer groove 3001. The buffer block 3002 can move up and down under the drive of the gear 1006 and the adjusting shaft 1007, and automatically reset after losing resistance.

[0064] More preferably, the end of the adjusting shaft 1007 away from the buffer block 3002 is provided with a lever 3004 vertically, and the universal joint 1018 also includes an arc-shaped ring 3005 sleeved on the outer wall of the lever 3004, and the arc-shaped ring 3005 is provided with a movable groove 3006.

[0065] In the initial state, both ends of the lever 3004 are simultaneously movable in the movable groove 3006, the other end of the universal joint 1018 is connected to the slider 1009, the first elastic element 1012 is a spring, and the generated elastic force is used to keep the slider 1009 at the center of the turntable 1013 at all times.

[0066] More preferably, a magnet is provided at one end of the slide bar 1011 extending outside the slide groove 1008, and an electromagnet is provided around the outer wall of the turntable 1013. When the gear 1006 slides up and down, the current in the electromagnet changes, thereby changing the magnetic strength, attracting the magnet and the slide bar 1011 to move closer to or away from the electromagnet.

[0067] In summary, when the cable blank 202 is bent or damaged, the contact height between the cable blank 202 and the roller 300 is inconsistent. The lifting rods 1002 on the two bases 1001 are relatively displaced, which causes the rack 1005 on one side to slide relative to the rack 1005 on the other side. At the same time, the gear 1006 starts to slide and move away from the balance position. The sliding rod 1011 and the slider 1009 are off-center, so the turntable 1013 reaches the off-center position, which increases the sliding stroke of the driven block 1015 in the clamp 1014.

[0068] At this time, as gear 1006 moves upward, it will also rotate along the relatively stationary rack 1005, causing turntable 1013 to rotate as well. This causes driven block 1015 to reach the maximum sliding stroke position, and conical block 201 and conical cavity 2001 slide into each other, preventing the sheath from continuing to be produced. This achieves automatic detection and alarm of defects, reduces product defects, and improves the quality of cable production.

[0069] Example 4

[0070] Reference Figures 1-8 This is the fourth embodiment of the present invention. This embodiment provides a control system. The method is applied to the above-mentioned torque-optimized twin-screw extruder. The roller 300 determines the operating status of the cable blank 202 and adapts to different input power of the drive motor 101, thereby optimizing the torque of the two transmission screws 102, achieving the best extrusion effect, and improving production intelligence and efficiency.

[0071] Specifically, a control system includes an information acquisition unit and a processing unit. The information acquisition unit is used to monitor the rotational speed data of each roller 300 in real time and record and generate statistical charts. The processing unit receives the rotational speed data and statistical charts, analyzes the rotational speed change trend, and finally matches different working states and generates different processing signals accordingly.

[0072] It also includes an execution unit, which is used to receive and process signals and control the rotation parameters of the drive motor 101 according to the processing signals, thereby controlling the rotation torque of the two transmission screws 102 respectively.

[0073] In this embodiment, there are six rollers 300, which are spaced apart at one end of the cable blank 202 entering the sheath shell 200. There are two transmission screws 102, which are controlled by two drive motors 101 to rotate. At the same time, the raw material feeding rate of the feed port 2002 changes synchronously with the drive motors 101, thereby ensuring the continuity of sheath extrusion and preventing intermittent or material shortage situations.

[0074] More preferably, the information acquisition unit arranges the speed values ​​measured by the speed sensor according to time and synchronously compares the rotational speed statistics of each roller 300. When the values ​​of each roller 300 are all 0, a stop signal is output to the processing unit. The processing unit matches the stop working state and controls the drive motor 101 to be in standby state.

[0075] Preferably, when the rotational speed values ​​of the roller 300 are not all 0, the rotational speed statistics and position information corresponding to the roller 300 are output to the processing unit, and the processing unit compares the rotational speed of the roller 300.

[0076] There are two positions on the cable blank 202, located on both sides of the sheath shell 200, namely the feeding position and the discharging position. When the rotation speed of the roller 300 at the corresponding position meets the speed requirement, the corresponding processing signal is output.

[0077] When the three rollers 300 at the same position along the axis of the cable blank 202 rotate at the same speed, the feeding or discharging processing signal is matched, and the discharging or feeding processing signal is determined according to the position information of the three rollers 300 that meet the speed requirements.

[0078] Among them, when the three rollers 300 at the same position in the axial direction of the cable blank 202 rotate at different speeds, a fault processing signal for the cable blank 202 is output.

[0079] Furthermore, when the rotational speed values ​​of rollers 300 are not all zero, the processing unit compares the rotational speed statistics of each roller 300.

[0080] Among them, when the speed difference between the three rollers 300 at the same position exceeds the set maximum difference, a fault processing signal for cable blank 202 is output.

[0081] When the speed comparison does not exceed the set threshold, a processing signal with a corresponding value is output based on the average speed value.

[0082] Furthermore, when the execution unit receives a stop signal or a fault handling signal for the cable blank 202, the drive motor 101 stops working;

[0083] Upon receiving the processing signal of the feeding position, the feed inlet 2002 is controlled to start feeding, and the drive motor 101 is controlled to start preheating and rotate at low speed.

[0084] Upon receiving the processing signal from the discharge position, the feeding at the inlet 2002 is stopped, and the drive motor 101 is controlled to rotate at low speed to discharge excess molten material, facilitating the later cleaning of the hollow cylinder 103.

[0085] When a fault handling signal is received for cable blank 202, the rotation of drive motor 101 and feeding of feed inlet 2002 are stopped, and an alarm signal is issued to prompt maintenance personnel to resolve the issue.

[0086] When a processing signal corresponding to the average rotational speed is received, the output power parameters of the drive motor 101 are adjusted according to the set parameters, and the output torque of the drive motor 101 to the transmission screw 102 is adjusted respectively. The output torque of the two transmission screws 102 is optimized to achieve the best extrusion effect, ensuring that the thickness and continuity parameters of the extruded cable sheath meet the production quality requirements. At the same time, the sheath thickness is automatically adapted to cables of different diameters and thicknesses, improving production intelligence and production efficiency.
