Description

Technical Field

[0001] The present invention relates to the technical field of winding disc winding, and particularly to a winding disc that can be tightened. Background Art

[0002] A winding disc is a kind of disc tool. Winding discs are divided into two types: large and small. The diameter of a large winding disc exceeds one meter, and some even reach more than five meters. The typical representatives are mostly wooden large-scale transportation and logistics wire discs. The diameter of a small winding disc is only between 30 cm and 100 cm. The typical representatives are winding discs made of ABS flame-retardant materials and high-temperature-resistant materials. The enameled wires wound on them also have various sizes, ranging from relatively thin wires to cables with a diameter greater than 30 cm. Winding discs are also widely used in the coil winding process during transformer production;

[0003] During the winding process of traditional winding discs, they usually do not have the uniformity of winding and only have the winding function. There is already a kind of winding disc. In order to make the winding uniform, a reciprocating screw is added in front of the winding disc, and a lead wire cylinder is added on the reciprocating screw for winding guidance. This method solves the problem of uneven winding to a certain extent, and it is also the method adopted by most winding components to ensure the winding uniformity. However, according to the use experience, it is found that this method can obtain a tight winding when the wire diameter is small, but when the enameled wire has a certain diameter, since the lead wire cylinder mostly corresponds to the inner wall position of the wire disc when it is at the end of the reciprocating screw, and the lead wire cylinder will turn after moving to this position, this will cause gaps for the enameled wire at the inner wall position of the winding disc. This situation can be ignored for thin wires, but when facing enameled wires with a certain size, the gaps are large. At the same time, as the number of winding layers increases, the length of the wire that can be wound in a single layer of the wire disc will be correspondingly affected, which will also affect the final winding length and tightness. That is to say, as the winding process progresses for traditional winding discs, there will be space at the edge of the wire disc. Especially when winding wires with a certain size, there is still room for improvement in terms of tightness and the length that can be wound. Summary of the Invention

The rack row is slidably connected with the inner wall of the slider. The inner wall of the slider is fixedly connected with two groups of connecting collar ones.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] First, considering that most traditional uniform winding devices adopt the form of a reciprocating screw, there will be a certain area of voids at the winding edge in this way. This situation is more obvious when the diameter of the enameled wire being wound is thicker. Through the cooperation of structures such as the pressing plate, the moving frame, and the limiting shaft, the present invention realizes that during the winding process of the cable, the sorting is neat and it is not easy to knot. At the same time, there will be a pause at the edge of the winding path. Through the pause, the cable wound at the edge of the roller shaft can wind and supplement most of the remaining space area, and then turn to carry out the second-layer winding work, so that the winding is tighter;

[0017] Meanwhile, the pause time increases with the winding time. Therefore, as the winding thickness increases, the length of the cable that can be wound in a single pass by this device is greatly improved. At the same time, compared with some devices that increase the path length of the reciprocating screw, the present invention will not cause bending at the edge during the winding of the cable, providing good protection for the product.

[0018] Second, through the cooperation of structures such as the connecting collar one, gear one, and traveling track, the present invention first rotates and cleans the cable surface with the brush rings on both sides during the guiding and winding process, and the brush ring in the middle performs reciprocating deflection cleaning when it pauses briefly on both sides, realizing the function of removing substances such as dust and soil attached to the cable surface, preventing the formation of voids at the winding part due to the attachment of dust and soil on the surface after being wound into a roll, which affects the tightness of winding.

[0019] At the same time, when the slider pauses, this device can still ensure the progress of the treatment process and will not stop with the pause. By setting three brush rings to cooperate with each other, when it pauses on both sides, since the length of the cable wound on other areas is relatively short, the work of one brush ring can meet the requirements. During the moving and winding process, through the cooperation of two brush rings, the treatment is more targeted, avoiding the situation where the brush ring is overused and its lifespan is reduced.

[0020] Third, through the cooperation of structures such as the binding belt box, inserting rod group, and tightening groove, after all the winding is completed, the operator can pull the binding belt in the binding belt box to perform final limiting on the last section of the cable, further improving the fastening performance.

[0021] At the same time, after the hook is connected to the hanging ring on the binding belt, the inserting rod group can be moved, making the binding belt located at the gap between the inserting rod group and the second disk. Since the distance between the inserting rod group and the second disk is less than the thickness of the hanging ring at the end of the binding belt on the binding belt box, it avoids the failure of the hook connection and the dangerous situation of the rapid reset of the binding belt under the condition of the spiral spring assembly, and further provides guarantee for the tightness of winding.

[0033] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0034] Embodiment 1:

[0035] Please refer to Figures 1 to 10 , the present invention provides a retractable wire reel, including a bracket 1, the inner wall of the bracket 1 is rotatably connected with a wire reel 2 and a threaded rod 3, the wire reel 2 includes a disk body 1 201, a roller shaft 203 and a disk body 2 202, the inner wall of the bracket 1 is fixedly connected with a winding motor 4 and a driving motor 5 respectively, the winding motor 4 is fixedly connected with the surface of the disk body 1 201, and the driving motor 5 is fixedly connected with the end of the threaded rod 3;

[0036] The inner wall of the bracket 1 is fixedly connected to two sliding rods 6, and the rod walls of the two sliding rods 6 are slidably connected to a slider 7. Two gears 1 8 and a gear 2 9 are arranged below the slider 7. The inner walls of the two gears 1 8 and one gear 2 9 are fixedly connected to a brush ring 10. The tightenable winding drum is specially used for winding and transporting products such as cables, ropes, enameled wires, etc. with a certain size. When in use, the device is set up on a transport carrier such as a ship. Taking the transfer cable as an example, the cable is passed through the brush ring 10 between the two gears 1 8 and one gear 2 9, and is wound on the roller 203. By starting the winding motor 4 to drive the drum 2 to rotate, the cable winding and winding work can be completed.

[0037] It also includes a winding component, a cleaning component and an anti-drop component arranged on the bracket 1. The winding component causes the slider 7 to move back and forth horizontally, and stops intermittently when turning. The stop time increases with the increase of the thickness of the winding wire on the roller 203. The cleaning component is connected to the winding component in a transmission manner, so that when the slider 7 moves back and forth, the two gears 1 8 continue to rotate, and when the slider 7 stops intermittently at both ends of the path, the two gears 1 8 stop synchronously and switch to the rotation of the gear 2 9.

[0038] The winding component includes a sleeve 11 and an adaptable plate 22. The inner wall of the sleeve 11 is threadedly connected to the rod wall of the threaded rod 3. The outer wall of the sleeve 11 is rotatably connected to the inner wall of the slider 7. Through grooves are provided on both sides of the slider 7. The groove walls of the two through grooves are slidably connected to a moving frame 12. Both sides of the moving frame 12 are fixedly connected to a pressure plate 13. The opposite sides of the two pressure plates 13 are fixedly connected to a pressure spring 14. The ends of the two pressure springs 14 are fixedly connected to the surface of the slider 7. The inner wall of the moving frame 12 is fixedly connected to a fixed shaft 15. The inner wall of the slider 7 Four limiting shafts 16 are fixedly connected, and the shaft walls of the four limiting shafts 16 are slidably connected with a slide plate 17. The top surface of the slide plate 17 is connected to the inner wall of the slider 7 through a return spring 18. The bottom surface of the slide plate 17 is fixedly connected with a synchronization plate 19. The surface of the synchronization plate 19 is provided with a V-shaped groove 20. The shaft wall of the fixed shaft 15 is slidably connected with the groove wall of the V-shaped groove 20. The outer wall of the sleeve 11 is provided with a socket for inserting the synchronization plate 19. The opposite sides of the inner wall of the bracket 1 are fixedly connected with a clamping block 21 adapted to the slider 7, and a sensing element is arranged in the clamping block 21.

[0039] The inner wall of the bracket 1 is symmetrically fixedly connected with two sliding frames 23, the two ends of the adaptation plate 22 are respectively slidably connected to the inner walls of the two sliding frames 23, the inner walls of the two sliding frames 23 are fixedly connected with adaptation springs 24, the ends of the two adaptation springs 24 are respectively fixedly connected to the two ends of the adaptation plate 22, and the bottom of the inner walls of the two sliding frames 23 are provided with distance sensors. The inner wall of the bracket 1 is provided with a central control component 25, and the central control component 25 is electrically signal-connected with the distance sensor, the winding motor 4 and the drive motor 5.

[0040] More specifically, in this embodiment: during the process of winding up, in order to ensure that the cable is wound tightly without knotting, the driving motor 5 can be started synchronously. The driving motor 5 drives the threaded rod 3 to rotate, thereby giving the sleeve 11 a tendency to rotate synchronously. At this time, since the synchronous plate 19 is inserted into the socket on the sleeve 11, and since the synchronous plate 19 is synchronously constrained and adjusted with the four limiting shafts 16, that is, the slider 7, and the slider 7 is constrained by the two slide rods 6, it will not rotate around the threaded rod 3. Therefore, during the rotation of the threaded rod 3, only the sleeve 11 will move along the rod wall of the threaded rod 3. During this process, the structure inside the slider 7 and the three brush rings 10 below will be synchronously driven to move, so that as the cable is wound on the wire reel 2, the cable will move along the surface of the wire reel 2, so that the winding order is regular and it is not easy to knot;

[0041] When it moves close to the inner wall of the bracket 1, at this time, the pressing plate 13 on one side will first contact the clamping block 21. As the slider 7 continues to move, the pressing plate 13 will be squeezed and no longer move with the slider 7. Combining Figure 8 with Figure 10 , at this time, a relative displacement will be generated between the pressing plate 13 and the slider 7. At this time, the moving frame 12 will be driven to move synchronously, and then the fixed shaft 15 will move synchronously, that is, a relative movement will be generated between the fixed shaft 15 and the synchronous plate 19, so that the fixed shaft 15 slides along the groove wall of the V-shaped groove 20. In this way, the synchronous plate 19 can be pushed to move upward through the V-shaped groove 20, so that it is disengaged from the socket on the sleeve 11. At this time, the return spring 18 is squeezed. Since the sleeve 11 loses the synchronous limit constraint of the synchronous plate 19 on it, during the rotation of the threaded rod 3 thereafter, the sleeve 11 will be driven to rotate continuously synchronously. Since the slider 7 is in contact with the clamping block 21, it cannot move forward any more. At this time, the slider 7 is at the end of the threaded rod 3, and at the same time, the cable winding is in contact with the disk body one 201 or the disk body two 202, that is, at the end of the winding area;

[0042] During the above process, the induction element in the clamping block 21 is induced, so that the distance sensor in the sliding frame 23 is started to measure the distance between it and the adaptor plate 22. The thicker the winding on the roller shaft 203, the smaller the distance. The current winding degree is judged by the distance measurement, and the data is transmitted to the central control component 25 for judgment, so as to determine the remaining rotation time of the driving motor 5 next. After reaching the time, its output end starts to reverse. Before it starts to reverse, since the slider 7 remains in this position and the wire reel 2 continues to wind, the wound cable will wind the end, and there will be no space left here due to an immediate turn. The setting of converting the distance measurement into time in the above process can be easily realized through the existing controller. This embodiment only uses this process, and the specific principle will not be elaborated;

[0043] When the output end of the driving motor 5 flips, at this time, the sleeve 11 is re-engaged with the synchronization plate 19. At the same time, the rotation of the threaded rod 3 gives the slider 7 a tendency to shift reversely. As a result, after the synchronization plate 19 is engaged into the sleeve 11, it will not come out again, and the reset spring 18 gradually returns, thereby causing the slider 7 to translate reversely;

[0044] In the above manner, first, the cable can be neatly sorted during the winding process, and it is not easy to knot, so the winding is tight. At the same time, a pause will be generated at the edge of the winding path. Through the pause, the cable wound at the edge of the roller 203 can wind and supplement most of the remaining space area, and then turn to perform the second-layer winding work. In this way, the tightness of the cable winding is improved, and it is in close contact with the disk body one 201 or the disk body two 202 at the edge. Moreover, the pause time increases with the winding time, and as the winding thickness increases, the length of the cable that can be wound by this device at one time is greatly improved;

[0045] It should be noted that considering that most traditional devices use the form of a reciprocating screw, during the winding process, since this method directly turns at the edge, there will be a certain area of voids at the winding edge. This phenomenon is more obvious when the diameter of the wound cable is thicker. There are also some devices that avoid the void area at the edge by increasing the path length of the reciprocating screw, but this method will cause the cable to bend at this point. This device has no such defects.

[0046] Embodiment 2, on the basis of the above embodiment:

[0047] Please refer to Figures 6 to 10 , the cleaning component includes two arc grooves 26, both of which are opened on both sides of the sleeve 11. The groove walls of the two arc grooves 26 are both slidably connected with cleaning shafts 27. The ends of the two cleaning shafts 27 are fixedly connected together with a rack row 28. The rack row 28 is slidably connected with the inner wall of the slider 7. The inner wall of the slider 7 is fixedly connected with two groups of connecting collar one 29. The outer walls of two gears one 8 are respectively rotatably connected with the inner walls of the two groups of connecting collar one 29. The opposite sides of the two groups of connecting collar one 29 are fixedly connected together with a connecting collar two 30 through a fixing rod group. The gear two 9 is rotatably connected with the inner wall of the connecting collar two 30. The teeth of the rack row 28 are meshed with the teeth of the gear two 9. The bottom surfaces of the two sliding rods 6 are both provided with traveling tracks 31. The teeth of the two gears one 8 are respectively meshed with the two traveling tracks 31.

[0048] More specifically, in this embodiment: Since the cable passes through the three brush rings 10, during the translation of the slider 7, two sets of connecting collar ones 29 will be driven to move synchronously, so that the two gears one 8 move, and then cooperate with the two traveling tracks 31 respectively, causing the two gears one 8 to rotate during the movement. In this way, the brush rings 10 provided thereon rotate. When the slider 7 is on both sides and does not move, the two gears one 8 stop rotating at this time. Since the sleeve 11 rotates continuously at this time, it will drive the two cleaning shafts 27 to perform reciprocating displacement through the two arc grooves 26. Thus, through the transmission of the two cleaning shafts 27, the rack row 28 performs reciprocating displacement, so that the gear two 9 performs reciprocating deflection;

[0049] By adopting the above method, first, the brush rings 10 on both sides rotate and clean during the guiding and winding process, and the brush ring 10 in the middle performs reciprocating deflection cleaning when stopping briefly on both sides, realizing the function of removing substances such as dust and soil attached to the surface of the cable, preventing voids from occurring at the winding place due to the attachment of dust and soil on the surface after being wound into a shape, and affecting the tightness of winding;

[0050] At the same time, when the slider 7 of this device pauses, the processing process can still be guaranteed to proceed and will not stop with the pause. At the same time, this device uses three brush rings 10 in cooperation. When pausing on both sides, since the length of the cable wound on the relatively other area is shorter, the work of one brush ring 10 can also meet the requirements. During the moving and winding process, by using two brush rings 10 in cooperation, the processing is more targeted, avoiding the situation that the brush rings 10 are overused and the service life is reduced.

[0051] Embodiment 3, on the basis of the above embodiment:

[0052] Please refer to Figures 1 to 4 , the anti-falling component includes: a restraint tape box 32 and a hook 33 fixedly connected to the bracket 1. A spiral spring component is arranged in the restraint tape box 32. The end of the restraint tape on the restraint tape box 32 is provided with a hanging ring that can be adapted to the hook 33. Six tightening grooves 34 are opened on the surfaces of the disk one 201 and the disk two 202, and six groups of protection components are correspondingly arranged on the surface of the disk two 202;

[0053] The protection component includes a protection groove opened on the surface of the disk two 202. The slot wall of the protection groove is slidably connected with a group of insertion rods 35. The group of insertion rods 35 is connected to the slot wall of the protection groove through a protection spring 36. The distance between the group of insertion rods 35 and the disk two 202 is less than the thickness of the hanging ring at the end of the restraint tape on the restraint tape box 32.

[0054] More specifically, in this embodiment: when all the winding is completed, the end section of the cable will fall on the wound spool 2. At this time, the operator can pull the binding strap in the binding strap box 32, pass it through the tightening groove 34, and pull it to the hook 33 behind the second disk body 202. The cable is finally limited by the binding strap, further improving the fastening property. At the same time, after the hook 33 is connected to the hanging ring on the binding strap, the plug rod group 35 can be moved so that the binding strap is located at the gap between the plug rod group 35 and the second disk body 202. Since the distance between the plug rod group 35 and the second disk body 202 is less than the thickness of the hanging ring at the end of the binding strap on the binding strap box 32, it avoids the risk of the connection at the hook 33 failing and the binding strap quickly resetting under the condition of the spiral spring assembly, and further ensures the tightness of the winding.

[0055] Working principle: When the retractable wire reel is in use, the cable is passed through the brush ring 10 between the two first gears 8 and the second gear 9 and wound around the roller shaft 203. By starting the winding motor 4 to drive the spool 2 to rotate, the winding and winding work of the cable can be completed. During the process of winding, in order to ensure the tightness of the cable winding and prevent knotting, the drive motor 5 can be started synchronously to drive the threaded rod 3 to rotate, so that the slider 7 makes a horizontal reciprocating displacement and pauses on both sides of the displacement path. Thus, during the winding process of the cable, the arrangement is neat and knotting is not likely to occur. Through the pause, the cable wound at the edge of the roller shaft 203 can wind and supplement most of the remaining space area, and then turn to carry out the winding work of the second layer;

[0056] During the winding process, when the slider 7 moves, the brush rings 10 on both sides rotate for cleaning, and when the slider 7 stops briefly, the brush ring 10 in the middle makes a reciprocating deflection cleaning, realizing the function of removing substances such as dust and soil attached to the surface of the cable, preventing the formation of voids at the winding due to the attachment of dust and soil on the surface after being wound into a roll, which affects the tightness of the winding;

[0057] When all the winding is completed, the end section of the cable will fall on the wound spool 2. At this time, the operator can pull the binding strap in the binding strap box 32, pass it through the tightening groove 34, and pull it to the hook 33 behind the second disk body 202. The cable is finally limited by the binding strap, further improving the fastening property. At the same time, after the hook 33 is connected to the hanging ring on the binding strap, the plug rod group 35 can be moved so that the binding strap is located at the gap between the plug rod group 35 and the second disk body 202. Since the distance between the plug rod group 35 and the second disk body 202 is less than the thickness of the hanging ring at the end of the binding strap on the binding strap box 32, it avoids the risk of the connection at the hook 33 failing and the binding strap quickly resetting under the condition of the spiral spring assembly, and further ensures the tightness of the winding.

[0058] Although embodiments of the present invention have been shown and described, those of ordinary skill in the art will appreciate that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
