Technical Field
[0001] This utility model relates to the field of pull-rope sensor technology, and in particular to a stainless steel rope winding device. Background Technology
[0002] Due to their compact structure and wide measurement range, draw-wire sensors are widely used in precision equipment such as miniature robotic arms and portable surveying instruments. To meet the long-distance measurement needs of miniaturized equipment, a stroke of 8 to 20 meters needs to be achieved through multi-layer winding, which places stringent requirements on the accuracy of the wire arrangement.
[0003] Most existing stainless steel rope take-up devices for pull-rope sensors use a single guide wheel structure, which causes the stainless steel rope to stack when repeatedly pulled back, resulting in inaccurate measurement data and affecting production efficiency. Utility Model Content
[0004] To overcome the above shortcomings, this utility model provides a stainless steel rope take-up device, which aims to improve the problem that existing stainless steel rope take-up devices, due to their single guide wheel structure, cause the stainless steel rope to stack up when repeatedly pulled back, resulting in inaccurate measurement data and affecting production efficiency.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a stainless steel rope take-up device, comprising an outer cover second, a servo motor fixedly installed inside the outer cover second, a lead screw fixedly connected to the output end of the servo motor, a limit block symmetrically rotating on one side of the lead screw, one side of the limit block fixedly connected inside the outer cover second, a guide block threadedly connected to the outer wall of the lead screw, a stainless steel rope wire slidably connected to the top of the guide block, a pull head fixedly connected to one end of the stainless steel rope wire, a sliding column symmetrically slidably connected inside the guide block, one side of the sliding column fixedly connected inside the limit block, a tension sensor provided on the outer wall of the stainless steel rope wire, one side of the tension sensor fixedly installed inside the outer cover second, a take-up structure fixedly connected to one side of the stainless steel rope wire, and a cleaning structure fixedly connected to one side of the outer cover second.
[0006] By adopting the above technical solution, when the stainless steel rope is pulled by the pull head, the tension sensor senses the tension data of the stainless steel rope, and the servo motor drives the lead screw to rotate, so that the guide block moves as needed to limit the sliding of the stainless steel rope. This achieves smooth and uniform pulling or retraction of the stainless steel rope, and improves the problem that existing stainless steel rope take-up devices, which use a single guide wheel structure, cause the stainless steel rope to stack when repeatedly pulled and retracted, resulting in inaccurate measurement data.
[0007] Preferably, the take-up structure includes a spool, one side of which is fixedly connected to one side of a stainless steel wire. A rotating shaft is rotatably connected inside the spool, and the outer wall of the rotating shaft is rotatably connected to the inside of an outer cover. A layer height laser sensor is fixedly installed on one side of the spool. A displacement encoder is fixedly connected to one end of the rotating shaft, and a spiral spring is fixedly connected to the other end of the rotating shaft. One end of the spiral spring is fixedly connected to an outer cover, and one side of the outer cover is fixedly connected to one side of the outer cover.
[0008] Preferably, the cleaning structure includes a mounting box, one side of which is fixedly connected to one side of the outer cover, a bracket is symmetrically fixedly connected inside the mounting box, and a dust collection box is fixedly connected inside the mounting box.
[0009] Preferably, a second spool is fixedly connected to one side of the first bracket, and a first spool is fixedly connected to one side of the second spool.
[0010] Preferably, an anti-static dust removal mesh is fixedly connected inside the second spool, and nylon ring brushes are uniformly fixedly arranged inside the anti-static dust removal mesh. A dust outlet pipe is fixedly connected to the other side of the second spool. Silicone scrapers are uniformly fixedly connected inside the first spool. An oil outlet pipe is fixedly connected to one side of the first spool, and a wire tube is fixedly connected to the other side of the first spool. The wire tube is slidably connected to one side of a stainless steel wire.
[0011] Preferably, the dust collection box has a slidably connected ash hopper inside, one side of the ash hopper is fixedly connected to one side of the mounting box, one side of the dust collection box is fixedly connected to one side of the dust outlet pipe, and the other side of the dust collection box is fixedly connected to one side of the oil outlet pipe.
[0012] Preferably, one side of the stainless steel rope is slidably connected to a second conduit, and one side of the second conduit is fixedly connected to the inside of the outer cover.

[0014] This utility model has the following beneficial effects: 1. In this utility model, when the stainless steel rope is pulled by the pull head, the tension sensor senses the tension data of the stainless steel rope and drives the lead screw to rotate through the servo motor, so that the guide block moves as needed and limits the sliding of the stainless steel rope. This achieves smooth and uniform pulling or retraction of the stainless steel rope, and improves the problem that the existing stainless steel rope take-up device uses a single guide wheel structure, which causes the stainless steel rope to stack when repeatedly pulled and retracted, resulting in inaccurate measurement data.
[0015] 2. In this utility model, when retracting the stainless steel rope, an automatic rebound is first achieved through a spiral spring. The spiral spring causes the rotating shaft to rotate, which in turn causes the reel to rotate automatically and retract the stainless steel rope. When the layer height laser sensor detects the start of layering, it prompts the control servo motor to control an appropriate speed and retract the rope at a uniform speed to prevent misalignment and inaccurate measurement.
[0016] 3. In this utility model, by pulling the stainless steel rope wire while it slides or retracts inside the second spool, the first spool, and the first tube, the oil stains are scraped off by the silicone scraper and the dust is brushed off by the nylon ring brush. This improves the problem of existing stainless steel rope take-up devices having no cleaning structure, which causes the stainless steel rope to adhere to oil stains and dust, resulting in diameter changes, inaccurate parameters, and shortened lifespan, thus affecting production efficiency.

[0019] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0020] Reference Figures 1-6 This utility model provides an embodiment of a stainless steel rope take-up device, comprising an outer cover 8, a servo motor 26 fixedly installed inside the outer cover 8, a lead screw 28 fixedly connected to the output end of the servo motor 26, a limit block 27 symmetrically rotating on one side of the lead screw 28, one side of the limit block 27 fixedly connected inside the outer cover 8, a guide block 16 threadedly connected to the outer wall of the lead screw 28, a stainless steel rope 7 slidably connected to the top of the guide block 16, a pull head 3 fixedly connected to one end of the stainless steel rope 7, a sliding column 29 symmetrically slidably connected inside the guide block 16, one side of the sliding column 29 fixedly connected inside the limit block 27, a tension sensor 17 provided on the outer wall of the stainless steel rope 7, one side of the tension sensor 17 fixedly installed inside the outer cover 8, a take-up structure fixedly connected to one side of the stainless steel rope 7, and a cleaning structure fixedly connected to one side of the outer cover 8.
[0021] Specifically, when the stainless steel rope 7 is pulled by the pull head 3, the tension sensor 17 senses the tension data of the stainless steel rope 7 and feeds it back to the servo motor 26 for judgment. The servo motor then controls the speed in real time to drive the lead screw 28 in both directions and make it rotate. The rotation of the lead screw 28 causes the guide block 16 to move evenly in both directions. This even bidirectional movement of the guide block 16 allows the stainless steel rope 7 to be smoothly and evenly pulled or retracted to the take-up structure, achieving precise wire arrangement and preventing stacking. The take-up structure enables automatic retraction of the stainless steel rope 7 and precise wire arrangement, and facilitates cleaning. The structure allows for the cleaning of oil or dust adhering to the surface of the stainless steel rope 7 after use and during retraction, ensuring measurement accuracy. The sliding column 29 and the limiting block 27 enable the guide block 16 to move smoothly and control its movement range, ensuring the precision of the stainless steel rope 7. The outer cover 28 effectively protects the internal cleanliness of the device, improving the problem that existing stainless steel rope take-up devices, which use a single guide wheel structure, cause the stainless steel rope to stack when repeatedly pulled and retracted, resulting in inaccurate measurement data and affecting production efficiency.
[0022] Reference Figures 3-5The winding structure includes a coil 9, one side of which is fixedly connected to one side of a stainless steel rope 7. A rotating shaft 10 is rotatably connected inside the coil 9. The outer wall of the rotating shaft 10 is rotatably connected to the inside of the outer cover 8. A layer height laser sensor 25 is fixedly installed on one side of the coil 9. A displacement encoder 6 is fixedly connected to one end of the rotating shaft 10. A spiral spring 21 is fixedly connected to the other end of the rotating shaft 10. One end of the spiral spring 21 is fixedly connected to the outer cover 5. One side of the outer cover 5 is fixedly connected to one side of the outer cover 8.
[0023] Specifically, when retracting the stainless steel rope 7, the spiral spring 21 first achieves automatic rebound. The spiral spring 21 causes the rotating shaft 10 to rotate, which in turn causes the reel 9 to rotate automatically and retract the stainless steel rope 7. During retraction, when the layer height laser sensor 25 detects the start of layering, it prompts the servo motor 26 to control the appropriate speed and retract at a uniform speed to prevent misalignment and inaccurate measurements. The displacement encoder 6 can accurately measure the distance of the stainless steel rope 7 when it is retracted or pulled out. The outer cover 5 can restrict the spiral spring 21 from tightening and releasing inside, and also prevent dust and other foreign objects from entering the interior and affecting use. The reel 9 can achieve winding and retraction, and the rotating shaft 10 can tighten or release the spiral spring 21. Through the action of the spiral spring 21, the reel 9 can automatically tighten the stainless steel rope 7, which improves the problem of existing winding devices not being able to accurately measure the pulling distance data, resulting in frequent errors in production data.
[0024] Reference Figure 1 and Figure 6The cleaning structure includes a mounting box 2, one side of which is fixedly connected to one side of an outer cover 8. A bracket 14 is symmetrically fixedly connected inside the mounting box 2. A dust collection box 18 is fixedly connected inside the mounting box 2. A wire spool 13 is fixedly connected to one side of the bracket 14. A wire spool 11 is fixedly connected to one side of the wire spool 13. An anti-static dust removal mesh 24 is fixedly connected inside the wire spool 13. Nylon ring brushes 23 are evenly fixedly arranged inside the anti-static dust removal mesh 24. A dust outlet pipe 19 is fixedly connected to the other side of the wire spool 13. Silicone scrapers 22 are evenly fixedly connected inside the wire spool 11. An oil outlet pipe 20 is fixedly connected to one side of the wire spool 11. One side is fixedly connected to a conduit 12, and the inside of the conduit 12 is slidably connected to one side of the stainless steel wire 7. The inside of the dust collection box 18 is slidably connected to a dust hopper 4, one side of the dust hopper 4 is fixedly connected to one side of the mounting box 2, one side of the dust collection box 18 is fixedly connected to one side of the dust outlet pipe 19, and the other side of the dust collection box 18 is fixedly connected to one side of the oil outlet pipe 20. One side of the stainless steel wire 7 is slidably connected to a conduit 15, one side of the conduit 15 is fixedly connected to the inside of the outer cover 28, one side of the outer cover 28 is fixedly connected to an L-shaped bracket 1, one side of the stainless steel wire 7 is slidably connected to the inside of the reel 11, and the other side of the stainless steel wire 7 is slidably connected to the inside of the reel 2 13.
[0025] Specifically, by pulling the pull head 3, the stainless steel wire 7 slides or retracts simultaneously inside the second spool 13, the first spool 11, and the first conduit 12. When passing through the first spool 11, the silicone scraper 22 effectively removes oil adhering to the surface of the stainless steel wire 7, and the removed oil is discharged through the oil outlet pipe 20. When passing through the second spool 13, the nylon ring brush 23 removes dust adhering to the surface of the stainless steel wire 7, and the anti-static dust removal net 24 and the dust outlet pipe 19 work together to discharge the brushed dust. The anti-static dust removal net 24 prevents static electricity from being generated during the pulling or retraction of the stainless steel wire 7, which could affect sensor components. The waste collection structure can collect the removed oil and dust. The automatic winding structure can automatically wind up the stainless steel rope 7. The support 14 fixes the spool 2 13. The dust collection box 18 can collect the oil and dust removed from the surface of the stainless steel rope 7 to prevent contamination of the device. The collected oil and dust can be quickly emptied by manually pulling the ash hopper 4, realizing quick maintenance and improving production efficiency. The L-shaped bracket can realize multi-directional and multi-angle installation, improving installation efficiency. It improves the problem of existing stainless steel rope winding devices where the stainless steel rope is covered with oil and dust due to the lack of a cleaning structure, which leads to diameter changes, inaccurate parameters, and shortened lifespan, affecting production efficiency.
[0026] Working Principle: During use, when the stainless steel rope 7 is pulled by the pull head 3, the tension sensor 17 senses the tension data of the stainless steel rope 7 and feeds it back to the servo motor 26 for judgment. The servo motor 26 then controls the speed in real time to drive the lead screw 28 in both directions and rotate it. The rotation of the lead screw 28 causes the guide block 16 to move evenly in both directions. This even bidirectional movement of the guide block 16 allows the stainless steel rope 7 to be smoothly and evenly pulled or retracted to the take-up structure. The sliding column 29 and the limit block 27 ensure the smooth movement of the guide block 16 and control its range of movement. The spiral spring 21 causes the rotating shaft 10 to rotate, which in turn causes the coil 9 to automatically rotate and retract the stainless steel rope 7. When the layer height laser sensor 25 detects the start of layering, it prompts the servo motor 26 to control the appropriate speed and retract the rope evenly. The displacement encoder 6 accurately measures the distance. The outer cover 5 restricts the tightening and releasing of the spiral spring 21 within its enclosure. The coil 9... To achieve winding and retraction, the rotating shaft 10 allows the spiral spring 21 to be tightened or released. By pulling the cable puller 3, the stainless steel wire 7 slides or retracts simultaneously inside the second spool 13, the first spool 11, and the first tube 12. When passing through the inside of the first spool 11, the silicone scraper 22 effectively removes the oil adhering to the surface of the stainless steel wire 7, and then discharges the scraped oil through the oil outlet pipe 20. When passing through the inside of the second spool 13, the nylon ring brush 23 removes the stainless steel wire. Dust adhering to the surface of the steel wire rope 7 is brushed off, and then discharged through the cooperation of the anti-static dust removal net 24 and the dust discharge pipe 19. The anti-static dust removal net 24 can prevent static electricity generated when the stainless steel wire rope 7 is pulled or retracted. The wire spool 13 is fixed by the bracket 14. The removed oil and dust are collected by the dust collection box 18. The collected oil and dust are quickly emptied by manually pulling the ash hopper 4. The L-shaped bracket can realize multi-directional and multi-angle installation.
