Description

Technical Field

[0001] This utility model belongs to the technical field of internal support and fixing of plastic flat wire winding drums, specifically relating to an elastic internal support and fixing device for plastic flat wire winding drums. Background Technology

[0002] Plastic flat yarn is a key material used in circular looms to weave tubular plastic base fabric. It requires the combination of warp and weft plastic flat yarns to form a tubular plastic base fabric. The formation process of plastic flat yarn is as follows: polypropylene granular raw material is melted at high temperature through a drawing machine and extruded into a plastic film through a die. Then, it is cooled, shaped, and cut into plastic flat yarns. After the plastic flat yarn is formed, it needs to be wound onto a take-up drum as either the weft or the warp. The wound plastic flat yarn weft or warp take-up drum is then installed on a circular loom, and the tubular plastic base fabric is formed through the circular loom.

[0003] Because the take-up drum needs to rotate when winding plastic flat yarn, centrifugal force is generated during the rotation. Therefore, securing the take-up drum itself is crucial, as it affects whether the plastic flat yarn can be wound smoothly. Patent application number CN202421202011.3, entitled "A Yarn Inlet Frame for a Water Jet Loom," specifically discloses that "multiple support rods are installed along the axial direction on the frame. One end of each support rod is provided with a clamping assembly for clamping both ends of the yarn bobbin. The side wall of each support rod has a long groove, and an installation cavity is formed on the support rod. A clamping assembly is installed inside the installation cavity to press against the inner wall of the yarn bobbin." To clamp both ends of the yarn bobbin and prevent it from slipping and jumping, the clamping assembly includes clamping blocks and baffles. The clamping blocks are movably mounted on the support rod at the end away from the bracket. The clamping blocks slide radially along the support rod via sliding strips on both sides. The clamping blocks are arranged in pairs, with the two clamping blocks near each other fixedly connected to the two ends of a spring, and the two clamping blocks away from each other forming an inclined plane on the left side towards the axis of the support rod. The baffles slide on a long groove and abut against the inner wall of the mounting cavity and the outer surface of the support rod, respectively. An elastic telescopic rod is arranged along the axial direction of the support rod in the mounting cavity. The elastic telescopic rod is located near the bracket, and its two ends are fixedly connected to the support rod and the baffle, respectively. The baffle has a clamping block groove near the clamping block, which matches the clamping block. A pressure block is fixedly mounted on the right side of the clamping block. A limiting block is provided at the end of the sliding strip. An anti-slip plate is provided on the left side of the clamping block, and an anti-slip ring is provided on the right side of the baffle.

[0004] In the aforementioned prior art, when replacing the yarn spool, simply squeeze the two clamping blocks to move them towards the axis of the support rod. At this time, the right side of the yarn spool is no longer obstructed, and the clamping block disengages from the inner wall of the yarn spool, retracting the support rod. The elastic telescopic rod pushes the yarn spool to the right side of the support rod through the baffle, allowing the worker to easily remove the yarn spool. The main technical problem with the aforementioned prior art is that the yarn spool (take-up drum) is fixed manually, resulting in low automation and failing to meet the automated coordination requirements of a robotic arm for changing take-up drums. Therefore, the inventor has developed an elastic internal support and tightening fixing device for plastic flat yarn take-up drums to quickly achieve internal support and tightening fixation of the take-up drum, while simultaneously unlocking the fixation, thus meeting the requirements for automated coordination with a robotic arm for changing take-up drums. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides an elastic internal support and fixing device for flat yarn weft winding drums. This utility model has a simple structure and a scientific and reasonable design.

[0006] The technical solution adopted in this utility model is as follows: an elastic internal support and fixing device for a plastic flat wire winding drum, including a bracket, a mounting frame, and a control system. The bracket is T-shaped, and the mounting frame is fixedly installed at the center of the left side of the bracket. The control system is fixedly installed at the upper front of the left side of the bracket. A drive device is installed at the rear of the mounting frame and is rotatably and fixedly connected to the bracket through the mounting frame. A pneumatic push rod is fixed at the center of the left side of the mounting frame, and the telescopic rod of the pneumatic push rod extends through the mounting frame to the right side of the mounting frame. The pneumatic push rod and the drive device are arranged in a front-rear correspondence. A shaft cylinder is installed in the inner ring of a rotary bearing, and a driven gear is fixedly installed on the left side of the shaft cylinder. The shaft is a hollow cylindrical tube, with its left end extending to the middle of the mounting bracket and its right end flush with the right side of the inner ring of the slewing bearing. The slewing bearing is mounted in the center of the bracket, with end caps fixedly installed at both ends. The linkage rod is fixedly connected to the right end of the pneumatic push rod extension rod, which extends through the center of the shaft to the right side of the slewing bearing. The elastic inner support device is fixedly installed on the right side of the slewing bearing, with its internal center fixedly connected to the right end of the linkage rod. The pneumatic push rod extension rod drives the linkage rod to extend and retract, thereby driving the sliding elastic inner support action of the elastic inner support device to achieve elastic inner support and fixation of the inner wall of the winding drum.

[0007] The mounting frame is hollow and consists of fixed columns and fixed plates.

[0008] The control system includes a housing, which is square in shape. A display screen is fixedly installed in the middle of the left side of the housing. A PLC control module is fixedly installed in the middle of the upper right side inside the housing. A storage module is fixedly installed behind the PLC control module. A high-speed counter is fixedly installed in the lower rear side of the storage module. The display screen is fixedly connected to the PLC control module via signal lines. The PLC control module and the storage module are fixedly connected via signal lines. The high-speed counter is fixedly connected to the PLC control module via signal lines. The PLC control module is fixedly connected to the motion control module of the winding drum gripping robot via signal lines.

[0009] The drive device includes a servo motor, which is fixedly mounted on the rear side of the mounting bracket. The power output shaft of the servo motor extends through the mounting bracket to the right side of the mounting bracket. A rotating shaft is fixedly connected to the right end of the power output shaft of the servo motor. A drive gear is fixedly mounted on the rotating shaft near the left end. A bearing is fixedly mounted in the bracket, and the rotating shaft is mounted in the inner ring of the bearing. The rotating shaft extends through the inner ring of the bearing to the right side of the bearing seat on the right side of the bracket and is fixed by the bearing seat. An encoder is fixedly mounted on the right end face of the rotating shaft. The encoder is fixedly connected to the PLC control module and the high-speed counter respectively through signal lines.

[0010] The driving gear and the driven gear are arranged horizontally in a front-to-back manner, and the driving gear meshes with the driven gear for transmission.

[0011] The pneumatic actuator includes a pneumatic actuator body, which is installed at the center of the left side of the mounting bracket. Magnetic switch one is fixedly installed at the front left end of the pneumatic actuator body, and magnetic switch two is fixedly installed at the front right end of the pneumatic actuator body. Magnetic switch one and magnetic switch two are respectively fixedly connected to the PLC control module via signal lines. The pneumatic actuator body is fixedly connected to the air source solenoid valve via an air pipe, and the air source solenoid valve is fixedly connected to the PLC control module via a signal line.

[0012] The elastic internal support device includes a support shaft, which is fixedly mounted on the right end face of the inner ring of the slewing bearing. The support shaft is hollow, with an open left end and a closed right end. A sliding column is located at the inner center of the support shaft. An elastic internal support mechanism is evenly arranged around the left and right ends of the sliding column in the circumference of the sliding column. The elastic internal support mechanism is slidably mounted on the inner wall of the support shaft. The left end of the sliding column is fixedly connected to the right end of the linkage rod.

[0013] The tensioning shaft includes a cylindrical body. A connecting ring is fixedly installed at the left end of the cylindrical body. The diameter of the connecting ring is larger than the diameter of the cylindrical body. The connecting ring is fixed to the right end face of the inner ring of the slewing bearing. Four sliding grooves are formed at equal angles around the inner wall of the cylindrical body. The sliding grooves pass through the left end of the cylindrical body and the connecting ring and extend to the right end of the cylindrical body. The sliding grooves are arc-shaped grooves. Four strip-shaped openings are formed at equal angles around the left and right ends of the cylindrical body. The strip-shaped openings pass through the body of the cylindrical body.

[0014] The elastic inner support mechanism includes a base, the bottom of which is fixed to the surface of the sliding column. Springs are symmetrically arranged on the upper part of the base. The inner support body is a cuboid with an arc surface at the top and a cuboid shape at the bottom.

[0015] The upper arc surface of the inner support body is slidably installed in the arc-shaped groove of the sliding groove.

[0016] The working process of this elastic internal support and fixing device for plastic flat yarn take-up drums is as follows: First, the operator presses the automatic mode on the control system's display screen. At this time, the PLC control module sends a start control command to the robot's motion control module. The robot grabs the take-up drum (without weft or warp plastic flat yarn) and installs it on the tensioning shaft of the elastic internal support device. After placement, the robot's motion control module sends a signal to the PLC control module that the take-up drum is installed. Upon receiving the signal, the PLC control module sends an open control command to the pneumatic push rod's air source solenoid valve. At this time, the pneumatic push rod's telescopic rod begins to extend. Magnetic switches one and two sense the extension distance of the telescopic rod in real time through the magnetic ring on the pneumatic push rod's telescopic rod. When the pneumatic push rod's telescopic rod extends to the extension distance preset in the PLC control module, the magnetic... The second switch senses the limit signal of the magnetic ring and transmits its position signal to the PLC control module. After receiving the position signal, the PLC control module sends a closing control command to the air source solenoid valve of the pneumatic push rod, and the pneumatic push rod stops moving. At this time, under the extension and retraction of the pneumatic push rod, the linkage rod moves to the right through the center of the shaft cylinder, and at the same time drives the sliding column to move to the right. During the movement of the sliding column to the right, the inner support body of the elastic inner support mechanism, which is evenly arranged on both ends of the sliding column, slides to the right along the sliding groove of the support shaft. At this time, due to the squeezing action of the sliding groove and the inner support body, the spring is in a compressed state. When it slides to the position of the strip opening, the elastic pressure of the spring begins to be released, and the spring bounces the inner support body up. At this time, the inner support body protrudes from the surface of the strip opening and elastically tightens and fixes the inner wall of the winding drum.Then, the PLC control module sends an start control command to the servo motor of the drive unit. The rotational power of the servo motor is transmitted to the rotating shaft through its power output shaft. The rotation of the rotating shaft drives the drive gear to rotate. Through the meshing transmission between the drive gear and the driven gear, the shaft cylinder rotates. The shaft cylinder drives the cylinder body supporting the shaft to rotate, thereby winding the plastic flat wire onto the take-up drum. As the take-up drum winds the plastic flat wire, the rotation of the rotating shaft drives the encoder disk to rotate. The encoder transmits the detected rotational pulse signals of the rotating shaft to the PLC control module and the high-speed counter. The high-speed counter records the number of pulse signals for the number of rotations of the rotating shaft and saves the data through the storage module. When the plastic flat wire is wound to the number of turns set by the PLC control module, the PLC control module sends a stop control command to the servo motor of the drive unit. At the same time, the PLC control module sends an start control command to the air source solenoid valve of the pneumatic push rod. The push rod retracts. When the magnetic switch detects the retraction position signal of the magnetic ring of the push rod, it sends the position signal of the push rod detected by the magnetic switch to the PLC control module. The PLC control module sends a closing control command to the air source solenoid valve of the pneumatic push rod (at the same time, the PLC control module sends a starting control command to the motion control module of the robot). Under the retraction action of the pneumatic push rod, the linkage rod moves to the left. The linkage rod drives the sliding column of the elastic inner support device to move to the left. At this time, the inner support body of the elastic inner support mechanism, which is evenly distributed on both ends of the sliding column, slides to the left along the sliding groove of the support shaft. When the inner support body leaves the strip opening, the inner support body of the elastic inner support mechanism contacts the sliding groove, forcing the spring to compress, thereby causing the inner support body to leave the strip opening. At this time, the inner support body loses its inner support and fixing effect on the inner wall of the winding drum. The robot can then remove the winding drum with the plastic flat wire wound on it.

[0017] The beneficial effects of this utility model are as follows: 1. Through the coordinated operation of the PLC control module, storage module, high-speed counter, and encoder of the drive device in the control system, the number of turns of plastic flat yarn wound on the take-up drum can be detected in real time, and the completion of the plastic flat yarn winding operation can be accurately determined. 2. Through the setting of the PLC control module, pneumatic push rod, magnetic switch one, magnetic switch two, linkage rod, and elastic internal support device in the control system, the functions of internal support fixing and internal support fixing of the inner wall of the take-up drum are realized. At the same time, the automatic control of the drive device and pneumatic push rod, as well as the intelligent linkage control with the take-up drum gripping robot, are realized, achieving automatic installation of the take-up drum and automatic removal after winding plastic flat yarn.

[0024] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0025] This utility model provides an elastic internal support and fixing device for flat yarn weft winding drum:

[0026] like Figure 1 and 2 As shown, the control system 3 is fixedly installed on the upper left front side of the support 1; the control system 3 includes a housing 31, which is square in shape; a display screen 32 is fixedly installed on the middle left side of the housing 31; a PLC control module 33 is fixedly installed on the middle upper right side inside the housing 31; a storage module 34 is fixedly installed on the rear side of the PLC control module 33; and a high-speed counter 35 is fixedly installed on the lower rear side of the storage module 34; the display screen 32 is fixedly connected to the PLC control module 33 via signal lines; the PLC control module 33 and the storage module 34 are fixedly connected via signal lines; and the high-speed counter 35 is fixedly connected to the PLC control module 33 via signal lines; the PLC control module is fixedly connected to the motion control module of the take-up drum 12 gripping robot via signal lines.

[0027] The aforementioned display screen 32 allows operators to automatically control the elastic internal support and fixing device via the display screen 32. Furthermore, operators can set the extension distance of the pneumatic push rod 5 via the display screen 32 (the extension distance of the extension rod is determined based on the distance between the inner support body 1133 of the elastic internal support mechanism 113 of the elastic internal support device 11 and the strip opening 114), and simultaneously set the number of turns of the plastic flat wire wound on the winding drum 12.

[0028] The above-mentioned configuration of PLC control module 33, storage module 34 and high-speed counter 35 enables encoder 46 to detect the rotation pulse signal of the rotating shaft 42 of drive device 4 in real time. The encoder 46 transmits the detected rotation pulse signal to PLC control module 33. At the same time, with the cooperation of high-speed counter 35, the number of rotations of tension shaft 111 is recorded and saved by storage module 34. When the take-up drum 12 rotates to the number of rotations set by PLC control module 33, it proves that the winding of plastic flat wire by take-up drum 12 is completed.

[0029] In addition, through the settings of PLC control module 33, on the one hand, automatic control of servo motor 41 of drive device 4 is realized; on the other hand, automatic control of telescopic rod of pneumatic push rod 5 is realized.

[0030] like Figure 1 As shown, the drive device 4 is installed at the rear of the mounting bracket 2, and is rotatably and fixedly connected to the bracket 1 through the mounting bracket 2. The drive device 4 includes a servo motor 41, which is fixedly installed at the rear of the mounting bracket 2. The power output shaft of the servo motor 41 extends through the mounting bracket 2 to the right side of the mounting bracket 2. The rotating shaft 42 is fixedly connected to the right end of the power output shaft of the servo motor 41. The drive gear 43 is fixedly installed near the left end of the rotating shaft 42. The bearing 44 is fixedly installed in the bracket 1, and the rotating shaft 42 is installed in the inner ring of the bearing 44. The rotating shaft 42 extends through the inner ring of the bearing 44 to the right side of the right bearing seat 45 of the bracket 1 and is fixed by the bearing seat 45. The encoder 46 is fixedly installed on the right end face of the rotating shaft 42. The encoder 46 is fixedly connected to the PLC control module 33 and the high-speed counter 35 respectively through signal lines. The drive gear 43 and the driven gear 7 are arranged horizontally front and back, and the drive gear 43 meshes with the driven gear 7 for transmission.

[0031] The aforementioned configuration of the drive device 4, servo motor 41, rotating shaft 42, drive gear 43, bearing 44, and bearing seat 45 enables the drive gear 43 to rotate under the rotational drive of the servo motor 41. Through the meshing transmission with the driven gear 7, the shaft cylinder 6 and the rotary bearing 9 are driven to rotate, thereby ultimately realizing the rotation of the tensioning shaft 111 of the elastic inner tensioning device 11. By utilizing the rotation of the tensioning shaft 111 and the inner tensioning body 1133 of the elastic inner tensioning mechanism 113 to fix the inner wall of the winding drum 12, the plastic flat wire can be wound onto the winding drum 12.

[0032] The aforementioned setup of the drive device 4 and encoder 46, with the rotating shaft 42 rotating, drives the code disk of the encoder 46 to rotate, using the encoder 46 to acquire the rotation pulse signal of the rotating shaft 42 and transmit this rotation pulse signal to the PLC control module 33. At the same time, the high-speed counter 35 is used to count the number of rotations of the rotating shaft 42. The PLC control module 33 uses a preset setting for the number of turns of the take-up drum 12 to wind the plastic flat wire. When the take-up drum 12 rotates to the preset number of turns, the PLC control module 33 sends a control command to the servo motor 41 to stop rotating, and the winding operation of the plastic flat wire is completed.

[0033] like Figure 1 , 3 As shown in Figure 4, the pneumatic push rod 5 is fixed at the center of the left side of the mounting frame 2. The telescopic rod of the pneumatic push rod 5 extends through the mounting frame 2 to the right side of the mounting frame 2. The pneumatic push rod 5 and the drive device 4 are arranged in a front-to-back correspondence. The pneumatic push rod 5 includes a pneumatic push rod body 51, which is installed at the center of the left side of the mounting frame 2. Magnetic switch 1 52 is fixedly installed at the front left end of the pneumatic push rod body 51, and magnetic switch 2 53 is fixedly installed at the front right side of the pneumatic push rod body 51. Magnetic switch 1 52 and magnetic switch 2 53 are respectively fixedly connected to the PLC control module 33 through signal lines. The pneumatic push rod body 51 is fixedly connected to the air source solenoid valve through an air pipe, and the air source solenoid valve is fixedly connected to the PLC control module 33 through a signal line.

[0034] The main purpose of the above-mentioned setup is that, by setting up magnetic switch 52 and magnetic switch 53, on the one hand, the position signal of the pneumatic push rod 5 telescopic rod can be located and tracked; on the other hand, the telescopic distance of the pneumatic push rod 5 telescopic rod can be controlled, thereby achieving precise control of the sliding distance of the elastic inner support mechanism 113 on the sliding column 112 of the elastic inner support device 11 in the sliding groove 1113, thus realizing the positioning of the inner support body 1133 and the strip opening 1114 during the telescopic sliding process.

[0035] like Figure 3As shown, the shaft cylinder 6 is installed in the inner ring of the slewing bearing 9, and the driven gear 7 is fixedly installed at the left end of the shaft cylinder 6. The shaft cylinder 6 is a hollow cylindrical shape, and the left end of the shaft cylinder 6 extends to the middle position of the mounting bracket 2. The right end of the shaft cylinder 6 is flush with the right end face of the inner ring of the slewing bearing 9. The slewing bearing 9 is installed at the center position of the bracket 1, and end caps 8 are fixedly installed at both ends of the slewing bearing 9. The tensioning shaft 111 includes a cylinder 1111, and a connecting ring 1112 is fixedly installed at the left end of the cylinder 1111. The diameter of the connecting ring 1112 is larger than the diameter of the cylinder 1111, and the connecting ring 1112 is fixed to the right end face of the inner ring of the slewing bearing 9.

[0036] The aforementioned arrangement of the shaft cylinder 6, driven gear 7, slewing bearing 9, tensioning shaft 111, cylinder body 1111, and connecting ring 1112, under the meshing transmission of the drive gear 43 and driven gear 7 of the drive device 4, drives the slewing bearing 9 and tensioning shaft 111 to rotate through the shaft cylinder 6, thereby driving the take-up drum 12 to rotate and providing rotational power for the take-up drum 12 to rotate and wind the plastic flat filament.

[0037] like Figure 3 As shown, the linkage rod 10 is fixedly connected to the right end of the telescopic rod of the pneumatic push rod 5, and the linkage rod 10 extends through the center of the shaft cylinder 6 to the right side of the rotary bearing 9; the left end of the sliding column 112 is fixedly connected to the right end of the linkage rod 10.

[0038] The main purpose of the above configuration is to use the telescopic movement of the pneumatic push rod 5 to drive the telescopic movement of the linkage rod 10, thereby realizing the telescopic sliding movement of the sliding column 112 in the elastic internal support device 11. Under the telescopic sliding action of the sliding column 112, the internal support body 1133 of the elastic internal support mechanism 113 is driven to slide along the sliding groove 1113.

[0039] like Figure 3 , 4 As shown in Figure 5, the elastic inner support device 11 is fixedly installed on the right side of the rotary bearing 9. The center of the elastic inner support device 11 is fixedly connected to the right end of the linkage rod 10. The pneumatic push rod 5 drives the linkage rod 10 to extend and retract, driving the sliding elastic inner support device 11 to achieve elastic inner support and fixation of the inner wall of the winding drum 12. The elastic inner support device 11 includes a support shaft 111, which is fixedly installed on the right end face of the inner ring of the rotary bearing 9. The support shaft 111 is hollow with an open left end and a closed right end. The sliding column 112 is installed at the center of the support shaft 111. The elastic inner support mechanism 113 is evenly arranged around the left and right ends of the sliding column 112. The elastic inner support mechanism 113 is slidably installed on the inner wall of the support shaft 111. The left end of the sliding column 112 is fixedly connected to the right end of the linkage rod 10.

[0040] The above-mentioned elastic internal support device 11, as well as the support shaft 111, sliding column 112 and elastic internal support mechanism 113 are arranged so that the elastic internal support mechanism 113 slides along the sliding groove 1113 of the support shaft 111 under the telescopic sliding action of the sliding column 112. When the elastic internal support mechanism 113 slides to the position of the strip opening 1114, the internal support body 113 bounces up under the elastic action of the spring 1132 of the elastic internal support mechanism 113, thereby realizing the internal support and fixation of the inner wall of the winding drum 12.

[0041] like Figure 3 , 4 As shown in Figure 5, the tensioning shaft 111 includes a cylindrical body 1111. Four sliding grooves 1113 are equally spaced around the inner wall of the cylindrical body 1111. The sliding grooves 1113 pass through the left end of the cylindrical body 1111 and the connecting ring 1112, and extend to the right end of the cylindrical body 1111. The sliding grooves 1113 are arc-shaped grooves. Four strip-shaped openings 1114 are equally spaced around the left and right ends of the cylindrical body 1111. The strip-shaped openings 1114 pass through the body of the cylindrical body 1111. The elastic inner support mechanism 113 includes a seat 1131. The bottom of the seat 1131 is fixed to the surface of the sliding column 112. Springs 1132 are symmetrically arranged on the upper part of the seat 1131. The inner support tensioning body 1133 is a cuboid with an arc surface at the top and a bottom. The upper arc surface of the inner support tensioning body 1133 is slidably installed in the arc-shaped groove of the sliding groove 1113.

[0042] The main purpose of this arrangement is as follows: Under the telescopic sliding action of the sliding column 112, the elastic inner support mechanism 113 slides along the sliding groove 1113 of the tensioning shaft 111. When the elastic inner support mechanism 113 slides to the right to the position of the strip opening 1114, the inner support tensioning body 113 springs up under the elastic action of the spring 1132 of the elastic inner support mechanism 113, thereby achieving an inner support and tight fixation of the inner wall of the take-up drum 12. When the inner support tensioning body 113 disengages from the strip opening 1114 due to the sliding of the sliding column 112 to the left, the inner support and tight fixation of the inner wall of the take-up drum 12 can be released. On the one hand, it serves to provide an inner support and tight fixation for the inner wall of the take-up drum 12; on the other hand, it serves to release the inner support and tight fixation of the inner wall of the take-up drum 12.

[0043] like Figure 1-5As shown, the working process of this elastic internal support and fixing device for plastic flat yarn take-up drum is as follows: First, the operator presses the automatic mode on the display screen 32 of the control system 3. At this time, the PLC control module 33 sends a start control command to the motion control module of the robot arm. The robot arm grabs the take-up drum 12 (without weft or warp plastic flat yarn) and installs it on the tensioning shaft 111 of the elastic internal support device 11. After placement, the motion control module of the robot arm sends a signal to the PLC control module 33 that the take-up drum 12 is installed. After receiving the signal, the PLC control module 33 sends an open control command to the air source solenoid valve of the pneumatic push rod 5. At this time, the telescopic rod of the pneumatic push rod 5 begins to extend. Magnetic switch one 52 and magnetic switch two 53 sense the extension distance of the telescopic rod in real time by sensing the magnetic ring on the telescopic rod of the pneumatic push rod 5. When the telescopic rod of the pneumatic push rod 5 extends to the extension distance preset in the PLC control module, magnetic switch two 53 senses the limit signal of the magnetic ring and sets its position. The signal is transmitted to the PLC control module 33. After receiving the position signal, the PLC control module 33 sends a closing control command to the air source solenoid valve of the pneumatic push rod 5, and the pneumatic push rod 5 stops moving. At this time, under the extension and retraction of the telescopic rod of the pneumatic push rod 5, the linkage rod 10 moves to the right through the center of the shaft cylinder 6, and at the same time drives the sliding column 112 to move to the right. During the process of the sliding column 112 moving to the right, the elastic inner support mechanism 1, which is evenly arranged on both the left and right ends of the sliding column 112, is activated. The inner support body 1133 of 13 slides to the right along the sliding groove 1113 of the support shaft 111. At this time, due to the squeezing action of the sliding groove 1113 and the inner support body 1133, the spring 1132 is in a compressed state. When it slides to the position of the strip opening 1114, the elastic pressure of the spring 1132 begins to be released, and the spring 1132 bounces up the inner support body 1133. At this time, the inner support body 1133 protrudes from the surface of the strip opening 1114 and elastically supports and fixes the inner wall of the winding drum 12.Then, the PLC control module 33 sends an start control command to the servo motor 41 of the drive device 4. The rotational power of the servo motor 41 is transmitted to the rotating shaft 42 through its power output shaft. The rotation of the rotating shaft 42 drives the drive gear 43 to rotate. Through the meshing transmission between the drive gear 43 and the driven gear 7, the shaft cylinder 6 is driven to rotate. The shaft cylinder 6 drives the cylinder 1111 of the tensioning shaft 111 to rotate, thereby winding the plastic flat wire onto the take-up drum 12. As the take-up drum 12 winds the plastic flat wire, the rotation of the rotating shaft 42 drives the encoder 46 to rotate. The encoder 46 transmits the detected rotation pulse signals of the rotating shaft 42 to the PLC control module 33 and the high-speed counter 35. The high-speed counter 35 records the number of pulse signals corresponding to the number of rotations of the rotating shaft 42 and saves this information through the storage module 34. When the plastic flat wire winds to the number of turns set by the PLC control module 33, the PLC control module 33 sends a stop control command to the servo motor 41 of the drive device 4. At the same time, the PLC control module 33 sends an open control command to the air source solenoid valve of the pneumatic push rod 5, causing the telescopic rod of the pneumatic push rod 5 to retract. When the magnetic switch 52 senses the retracted position signal of the telescopic rod magnetic ring, it sends the telescopic rod position signal sensed by the magnetic switch 52 to the PLC control module 33. The PLC control module 33 sends a closing control command to the air source solenoid valve of the pneumatic push rod 5 (at the same time, the PLC control module 33 sends a starting control command to the motion control module of the robot arm). Under the retracted telescopic rod action of the pneumatic push rod 5, the linkage rod 10 is driven to move to the left. The linkage rod 10 drives the sliding column 112 of the elastic inner support device 11 to move to the left. At this time, the sliding column 112 of the elastic inner support device 11 is set to move to the left. The inner support body 1133 of the elastic inner support mechanism 113, which is evenly arranged on both the left and right ends of the moving column 112, slides to the left along the sliding groove 1113 of the support shaft 111. When the inner support body 1133 leaves the strip opening 1114, the inner support body 1133 of the elastic inner support mechanism 113 contacts the sliding groove 1113, forcing the spring 1132 to compress, thereby causing the inner support body 1133 to leave the strip opening 1114. At this time, the inner support body 1133 loses its inner support and fixing effect on the inner wall of the winding drum 12; the robot arm can then remove the winding drum 12 with the plastic flat wire wound on it.
