Description

Technical Field

[0001] The invention relates to the technical field of cable sheath extrusion equipment, in particular to a twin-screw grouting extruder based on torque optimization and a control system thereof. Background Art

[0002] As key components for power and signal transmission, cables play a vital role in modern infrastructure. In traditional cable production processes, screw extruders are key equipment, and their performance directly impacts cable molding quality, production efficiency, and energy consumption. However, existing screw extruders commonly suffer from high energy consumption, uneven material mixing, and low temperature control precision. These issues hinder improvements in cable product quality and further enhance 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 can also trigger a series of chain reactions such as increased equipment wear and increased maintenance costs. Therefore, the development of a screw extruder and its control system that can optimize and control torque based on real-time conditions is of great significance for improving the technical level and market competitiveness of the cable production industry.

[0004] The existing Chinese patent with authorization announcement number CN210940369U discloses a twin-screw extruder for producing PVC cable sheath material, including a reduction gear box, a distribution box and a workbench. The reduction gear box includes a feed hopper, a control panel, a barrel, a head, a support frame, a reduction motor, an infrared detector, a rotating plate and a screw. The distribution box includes a movable door, a drive motor, a wire, a reserve battery and an insulating inner wall. An infrared detector and a feeder are installed inside the reduction gear box. Before each work starts, the infrared detector can automatically detect whether there is any abnormality in the parts in the device, replacing the early manual inspection, saving time and reducing the error rate. Secondly, the feeder can adjust the feeding speed to avoid damage to the device caused by accumulation of raw materials in the barrel. A reserve battery is installed in the distribution box. When the power outage occurs, the reserve battery starts to supply power, which will not affect the work progress and improve work efficiency.

[0005] However, since the sheath thickness in the above technical solution cannot be automatically adjusted according to the cable diameter, manual adjustment is required, which complicates the process and delays production. At the same time, the torque of the twin-screw cannot be optimized according to the extrusion speed, and it is difficult to maintain a stable output rate. The feeding speed cannot automatically match the cable blank feeding speed, resulting in uneven or poor continuity of the extruded sheath, low production intelligence and low production efficiency.

DETAILED DESCRIPTION

[0021] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0022] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0023] Secondly, the term "one embodiment" or "embodiment" 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 various places throughout this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive of other embodiments.

[0024] Example 1 Reference Figures 1 to 8 , which is the first embodiment of the present invention, provides a twin-screw grouting extruder based on torque optimization, including an extrusion assembly, a coating assembly and a detection assembly. The extrusion rate of the extrusion assembly is adjusted according to the feed speed of the cable embryo 202 to ensure the thickness and continuity of the sheath, ensure the processing accuracy of the cable, reduce processing errors, and automatically identify cable embryos 202 of different specifications and thicknesses to match the corresponding sheath thickness.

[0025] Specifically, a twin-screw grouting extruder based on torque optimization includes: The extrusion assembly includes a carrier 100, a driving motor 101 is provided on the carrier 100, a transmission screw 102 is provided at the output end of the driving motor 101, a hollow cylinder 103 is also provided on the carrier 100, and two transmission screws 102 are provided; The covering assembly includes a sheath shell 200 provided at the end of the hollow cylinder 103. A conical block 201 is slidably provided in the sheath shell 200. A cable embryo 202 is slidably provided in the conical block 201. The cable embryo 202 is pulled by an external force to slide along the axis of the conical block 201 for feeding; The detection assembly includes a roller 300 that is attached to the surface of the cable embryo 202. When the roller 300 rotates, the feeding speed of the cable embryo 202 is measured. There are at least two rollers 300. When the outer diameter of the cable embryo 202 changes, the roller 300 is driven to roll and rise, thereby driving the conical block 201 to move.

[0026] A conical cavity 2001 is provided inside the sheath shell 200 , and the end of the hollow cylinder 103 is vertically connected to the axis of the conical cavity 2001 . A feed port 2002 is also provided on the hollow cylinder 103 .

[0027] Among them, the raw materials required for the cable sheath enter the hollow cylinder 103 from the feed port 2002, and two transmission screws 102 are arranged in parallel in the hollow cylinder 103. The transmission screw 102 includes a crushing tooth segment and a mixing tooth segment, which are used to crush and mix the sheath raw materials while continuously transmitting them forward. A heating ring is provided on the outer shell of the hollow cylinder 103 to heat and melt the sheath raw materials.

[0028] More preferably, the conical cavity in the conical cavity 2001 and the cylindrical cavity of the hollow cylinder 103 are vertically connected to each other, so that as the conical block 201 slides in the conical cavity 2001 in the direction away from the outlet of the conical cavity 2001, the connection area between the hollow cylinder 103 and the conical cavity 2001 increases, thereby increasing the rate at which the molten sheath raw material enters the sheath shell 200.

[0029] Preferably, the conical cavity 2001 is movably engaged with the end conical portion of the conical block 201. As the conical block 201 moves away from the exit of the conical cavity 2001, the annular gap between the two becomes evenly larger, thereby increasing the thickness of the extruded sheath. Cable blanks 202 of different specifications and thicknesses can be automatically identified and matched to the corresponding sheath thickness.

[0030] More preferably, while the cable embryo 202 is sliding and feeding, the feed speed of the cable embryo 202 is measured by the fitted roller 300 and the data is recorded at the same time. The drive motor 101 optimizes the torque according to the feed speed of the cable embryo 202, so that the extrusion rate of the extrusion assembly matches the feed speed of the cable embryo 202, and as the feed speed of the cable embryo 202 changes, the extrusion rate automatically adjusts following the torque, reducing the uneven thickness of the sheath, ensuring the processing accuracy of the cable, and reducing processing errors.

[0031] Example 2 Reference Figures 1 to 8 , which is the second embodiment of the present invention. This embodiment is based on the previous embodiment, but differs in that the gap between the conical block 201 and the conical cavity 2001 is changed by moving the roller 300, so that the thickness of the extruded sheath is changed to adapt to cable embryos 202 of different diameters.

[0032] Specifically, the sheath shell 200 is provided with a base 1001 , a lifting rod 1002 is slidably provided on the base 1001 , a sliding slope 1003 is provided on the end surface of the lifting rod 1002 , and a support arm 1004 is rotatably provided on the base 1001 .

[0033] Among them, the lifting rod 1002 is provided with a roller 300 at one end close to the cable embryo 202 and both ends of the support arm 1004. The roller 300 at the end close to the cable embryo 202 is rolled and fitted on the surface of the cable embryo 202, and the axis is perpendicular to the axis of the conical cavity 2001.

[0034] More preferably, the roller 300 at the other end of the support arm 1004 is arranged parallel to the axis of the cable embryo 202, and is rolled and fitted on the surface of the landslide 1003. In this embodiment, the landslide 1003 is a right triangle fitted on the lifting rod 1002, and the end where the right angle is located is away from the cable embryo 202.

[0035] Among them, the support arm 1004 is a broken line rod with an obtuse opening. The opening position of the support arm 1004 is close to the cable embryo 202. The three rollers 300 close to the cable embryo 202 are distributed in a circular array on the surface of the cable embryo 202. There are two bases 1001 in total and they are distributed at intervals on the outer wall of the cable embryo 202.

[0036] Preferably, a rack 1005 is slidably provided on the sheath shell 200 , a gear 1006 is meshed with the rack 1005 , an adjustment 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 adjustment shaft 1007 .

[0037] One end of the lifting rod 1002 away from the cable embryo 202 is connected in parallel with the rack 1005 and slides synchronously, and the two racks 1005 are arranged parallel to each other.

[0038] Furthermore, a sliding groove 1008 is provided at one end of the universal joint 1018 away from the adjustment shaft 1007 , a slider 1009 is slidably provided in the sliding groove 1008 , and a sliding rod 1011 is provided on the slider 1009 .

[0039] Among them, a first elastic member 1012 is provided at one end of the sliding rod 1011 that slides through the sliding groove 1008, a turntable 1013 is provided on the slider 1009, a clamp 1014 is rotatably provided on the turntable 1013, a follower block 1015 is slidably engaged with the inner wall of the clamp 1014, and a connecting plate 1016 is provided between the follower block 1015 and the conical block 201.

[0040] 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 embedded in 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 embryo 202.

[0041] In summary, when the diameter specification of the incoming cable embryo 202 changes, the rollers 300 on the two bases 1001 are pushed outward at the same time, and the three rollers 300 are clamped with the outer wall at the same time. When the speed sensor detects that the rotation speed of each roller 300 changes synchronously in a step-like manner, it is determined that a change in the diameter specification has occurred. The lifting rod 1002 moves downward and drives the support arm 1004 to swing through the slide 1003. The rollers 300 continue to clamp the cable embryo 202 at the same time to prevent the cable embryo 202 from swinging and dislocating.

[0042] At the same time, when the diameter becomes larger, the lifting rods 1002 move away from each other, driving the two racks 1005 to move away from each other, so that the gear 1006 rotates and drives the turntable 1013 to rotate through the universal joint 1018, and the clamp 1014 located on the turntable 1013 moves accordingly, driving the driven block 1015 to move toward the cable entrance of the sheath shell 200, thereby increasing the gap between the conical block 201 and the conical cavity 2001, and increasing the thickness of the extruded sheath to adapt to cable blanks 202 of different diameters.

[0043] Example 3 Reference Figures 1-8 This is the third embodiment of the present invention. This embodiment is based on the previous embodiment, but differs in that the gear 1006 can move up and down. When a fault defect occurs in the cable embryo 202, the conical block 201 and the conical cavity 2001 are automatically closed to prevent the sheath from continuing to be produced, thereby realizing automatic detection and alarm of defects, reducing product defects, and improving cable production quality.

[0044] Specifically, a buffer groove 3001 is opened on the sheath shell 200 , a buffer block 3002 is slidably provided in the buffer groove 3001 , the adjustment shaft 1007 rotates and passes through the buffer block 3002 , and a second elastic member 3003 is provided between the buffer block 3002 and the inner wall of the buffer groove 3001 .

[0045] Among them, the second elastic member 3003 is a spring and two are symmetrically provided, 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 driven by the gear 1006 and the adjustment shaft 1007, and automatically reset after losing resistance.

[0046] More preferably, a lever 3004 is vertically provided at one end of the adjustment shaft 1007 away from the buffer block 3002 , and the universal joint 1018 further includes an arcuate ring 3005 sleeved on the outer wall of the lever 3004 , and a movable groove 3006 is formed on the arcuate ring 3005 .

[0047] Among them, 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, and the first elastic member 1012 is a spring, and the elastic force generated is used to maintain the slider 1009 at the center position of the turntable 1013 at all times.

[0048] More preferably, a magnet block is provided at one end of the slide rod 1011 extending outside the slide groove 1008, and electromagnets are 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 block and the slide rod 1011 to move closer to or away from the electromagnet.

[0049] In summary, when the cable embryo 202 is bent or damaged, the contact heights of the cable embryo 202 with the roller 300 are inconsistent, and the lifting rods 1002 on the two bases 1001 are relatively displaced, thereby driving the rack 1005 on one side to slide relative to the other rack 1005, and at the same time driving the gear 1006 to start sliding and deviate from the equilibrium position, the sliding rod 1011 and the slider 1009 are eccentric to the center position, so that the turntable 1013 reaches the eccentric position, which increases the sliding stroke of the driven block 1015 in the clamp 1014.

[0050] At this time, the gear 1006 moves upward and rotates along the relatively stationary rack 1005, so that the turntable 1013 also rotates, causing the driven block 1015 to reach the maximum sliding stroke position, and the conical block 201 slides and engages with the conical cavity 2001, preventing the sheath from continuing to be produced, realizing automatic detection and alarm of defects, reducing product defects, and improving cable production quality.

[0051] Example 4 Reference Figures 1-8 , which is the fourth embodiment of the present invention, provides a control system. This method is applied to the above-mentioned twin-screw grouting extruder based on torque optimization. The roller 300 is used to judge the operating status of the cable embryo 202, and the different input powers of the drive motor 101 are adapted to optimize the torque of the two transmission screws 102, thereby achieving the best extrusion effect and improving production intelligence and production efficiency.

[0052] Specifically, a control system includes an information acquisition unit and a processing unit. The information acquisition unit is used to monitor the speed data of each roller 300 in real time and record and generate statistical graphs. The processing unit receives the speed data and statistical graphs, and analyzes the speed change trend. Finally, it matches different working states and generates different processing signals accordingly.

[0053] The system further includes an execution unit for receiving a processing signal and controlling the rotation parameters of the driving motor 101 according to the processing signal, thereby controlling the rotation torques of the two transmission screws 102 respectively.

[0054] Among them, in this embodiment, there are six rollers 300, which are spaced apart and arranged at one end of the cable embryo 202 entering the sheath shell 200. There are two transmission screws 102, which are respectively controlled to rotate by two drive motors 101. At the same time, the raw material feeding rate of the feed port 2002 changes synchronously with the drive motor 101, thereby ensuring the continuity of the sheath extrusion and preventing intermittent or material shortage.

[0055] More preferably, the information acquisition unit arranges the speed values ​​measured by the speed sensor according to time, and synchronously compares the speed statistics of each roller 300. When the values ​​of each roller 300 are 0, a shutdown signal is output to the processing unit. The processing unit matches the shutdown working state and controls the drive motor 101 to be in standby state.

[0056] Preferably, when the rotation speed values ​​of the roller 300 are not all 0, the rotation speed statistics and position information corresponding to the roller 300 are output to the processing unit, and the processing unit compares the rotation speed comparison of the roller 300; There are two positions on the cable embryo 202, located on both sides of the sheath shell 200, which are the feeding position and the discharging position respectively. When the rotation speed of the roller 300 at the corresponding position meets the rotation speed requirement, the corresponding processing signal is output.

[0057] Among them, when the three rollers 300 at the same position in the axial direction of the cable embryo 202 have the same rotation speed, the processing signal of feeding or discharging is matched, and the output processing signal of feeding or discharging is determined according to the position information of the three rollers 300 that meet the rotation speed requirements.

[0058] When the three rollers 300 at the same position in the axial direction of the cable embryo 202 rotate at different speeds, a processing signal indicating a fault in the cable embryo 202 is output; Furthermore, when the rotation speed values ​​of the rollers 300 are not all zero, the processing unit compares the rotation speed statistics of the rollers 300; When the rotation speed comparison between the three rollers 300 at the same position exceeds the set maximum difference, a processing signal indicating a cable embryo 202 failure is output; When the speed comparison does not exceed the set threshold, a processing signal of a corresponding numerical value is output according to the average speed value.

[0059] Furthermore, when the execution unit receives a shutdown signal and a processing signal indicating a failure of the cable embryo 202 , the driving motor 101 stops working; After receiving the processing signal of the feeding position, the feeding port 2002 is controlled to start feeding, and the driving motor 101 is controlled to start preheating and rotate at a low speed; When the processing signal of the discharge position is received, the feeding of the feed port 2002 is stopped, and the driving motor 101 is controlled to rotate at a low speed to discharge the excess molten material, so as to facilitate the later cleaning of the hollow cylinder 103; When receiving the processing signal of the cable embryo 202 failure, the rotation of the driving motor 101 and the feeding of the feed port 2002 are stopped, and an alarm signal is issued to prompt the operation and maintenance personnel to solve the problem; When a processing signal of a numerical value corresponding to the average 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, and 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 automatically adapts to cables of different diameters and thicknesses, thereby improving production intelligence and production efficiency.
