[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] See also Figures 1 to 4The winding device of the present invention includes a winding mechanism 1 having a reel 10 and a winding disk 12 mounted on the reel 10 so as to rotate therewith, a rotating drive mechanism 2 detachably connected to the first end of the reel 10 to drive the reel 10 to rotate, and a disassembly and assembly limiting mechanism 3 detachably connected to the second end of the reel 10 to cooperate with the rotating drive mechanism 2 to suspend the winding mechanism 1; the second end of the reel 10 has a limiting hole 101, and the disassembly and assembly limiting mechanism 3 includes a supporting seat 31, a top 32 arranged at the top of the supporting seat 3 at a position corresponding to the reel 10, and a top push-pull mechanism 33 arranged on the supporting seat 31, which can pull the top 32 back into the supporting seat 3 and push the top 32 out of the supporting seat 3 to push it into the limiting hole 101 of the reel 10. Preferably, the winding device further comprises a guide mechanism 4 for introducing the strip into the winding disk 12 of the winding mechanism 1. The winding mechanism 1 is arranged on the back side of the winding mechanism 1. The strip enters the winding disk 12 under the guidance of the guide mechanism 4, and the strip is wound in the winding disk 12 under the rotation of the winding disk 12. In the winding device of this solution, the rotary drive mechanism 2 and the disassembly and assembly limiting mechanism 3 are respectively arranged at both ends of the winding mechanism 1. The winding mechanism 1 is suspended between the rotary drive mechanism 2 and the disassembly and assembly limiting mechanism 3, so that the winding mechanism does not need to be provided with a separate mounting bracket, so that the structure is simpler, the layout is more compact, and the manufacturing cost is reduced. The first end of the reel 10 is detachably connected to the rotary drive mechanism 2, and the second end of the reel 10 is limitedly matched with the retractable top 32 through the limiting hole 101. During installation, the first end of the reel 10 is connected to the rotary drive mechanism 2, and then the top 32 is extended into the limiting hole 101. The top 32 applies a force in the direction of the rotary drive mechanism 2, so that the reel 10 abuts against the output end of the rotary drive mechanism 2, thereby clamping the reel 10 from both ends of the reel 10 without restricting the rotation of the reel 10. This seemingly non-connected abutment method is very convenient for installing and disassembling the winding mechanism 1, and jumps out of the traditional thinking of screw connection, riveting and other detachable connection methods. The loading and unloading are very convenient and quick, which greatly improves the winding efficiency and reduces the manufacturing cost.

[0021] In this embodiment, lead strips are taken as an example for description.

[0022] In order to make the rotating drive mechanism 2, winding mechanism 1, guiding mechanism 4 and disassembly and limiting mechanism 3 of the winding device more integrated and complete, the winding device also includes a base 5, and the rotating drive mechanism 2, winding mechanism 1 and disassembly and limiting mechanism 3 are arranged on the base 5 in sequence from the first end (the left end in this embodiment) to the second end (the right end) of the base 5, and the guiding mechanism 4 is arranged on the base 5 at a position on the back side of the winding mechanism 1.

[0023] The rotary drive mechanism 2 includes a reduction box 21 and a reducer 22 connected to the reduction box 21, the reduction box 21 has a first output end 211 connected to the first end of the reel 10, the reduction box 21 also has a second output end 212 connected to the first end of the guide mechanism 4, and the second output end 212 is located above and behind the first output end 211.

[0024] In this embodiment, a clutch structure is used between the first end of the reel 10 and the first output end 211 of the reduction box 21. That is, the first output end 211 has a limiting groove 213 with an opening toward the direction of the reel 10, and the first end of the reel 10 has a limiting protrusion 102 corresponding to the position of the limiting groove 213, which is concave-convexly matched with the limiting groove 213. The first end of the reel 10 is concavely matched with the limiting groove 213 through the limiting protrusion 102, and the second end is pushed into the limiting hole 101 through the top 32 to apply a pushing force from the second end. Preferably, the limiting protrusion 102 is a conical protrusion, and the limiting groove 213 is a conical groove. The matching mode of the conical protrusion and the limiting groove 213 can play a guiding role and ensure easy disengagement.

[0025] In this embodiment, the reel 10 is a stepped shaft, a section close to the rotating drive mechanism 2 is a large diameter section, and a section close to the disassembly and assembly limiting mechanism 3 is a small diameter section. One end of the winding disk 12 close to the rotating drive mechanism 2 abuts against the end surface of the large diameter section, so that the winding disk 12 can be positioned, so that after each installation of the winding disk 12, the position of the winding disk 12 corresponds to the position of the fixed structure such as the guide mechanism 4. Further, the reel 10 includes a reel body 103 and a pressure cap 104 threadedly engaged with the second end of the reel body 103, and the limiting hole 101 is opened on the pressure cap 104 at a position corresponding to the top 32. The second end of the reel body 103 has an external thread, and the pressure cap 104 has an internal thread hole. When installing the pressure cap 104, the pressure cap 104 is screwed onto the external thread of the second end of the reel body 103.

[0026] The winding disk 12 has a drum that is inserted into the reel 10. A threaded hole (not shown) for fixing the drum is provided on the reel 10. A through hole is provided on the drum at a position corresponding to the threaded hole. When fixing the drum, a bolt is used to pass through the through hole on the drum from the outside to the inside and then locked to the threaded hole.

[0027] About disassembly and assembly limit mechanism 3

[0028] The disassembly and assembly limiting mechanism 3 includes a support seat 31, a tip 32 disposed at the top of the support seat 3 at a position corresponding to the position of the reel 10, and a tip push-pull mechanism 33 disposed on the support seat 31, which can pull the tip 32 back into the support seat 3 and push the tip 32 out of the support seat 3 to push into the limiting hole 101 of the reel 10. In this embodiment, in order to facilitate the installation and removal of the winding mechanism 1 and reduce labor costs, the disassembly and assembly limiting mechanism 3 also includes a disassembly and assembly disk auxiliary mechanism 34 disposed below the reel. Specifically:

[0029] The support seat 31 is erected on the base 5 at a position on the left end side of the winding mechanism 1. The upper end of the support seat 31 has an installation cavity 311 with an opening facing the direction of the reel 10, and the tip 32 is installed in the installation cavity 311 through a mounting seat 3213. Preferably, the installation cavity 311 transversely penetrates the support seat 31 along the left-right direction of the support seat 31, and a cover plate 312 is detachably connected to the second end of the support seat 31 (the end away from the winding mechanism 1).

[0030] The tip push-pull mechanism 33 includes a spring 331 and a pull handle 332. The fixed end of the spring 331 is fixed to the end of the mounting cavity 311 away from the reel 10. The free end of the spring 331 is connected to the mounting seat 321. The pull handle 332 has a connecting handle 3321 and a handle 3322 connected to the connecting handle 3321 in a bent shape. The connecting end of the connecting handle 3321 is pivoted to the outer periphery of the tip 32. The intersection of the connecting handle 3321 and the handle 3322 is pivoted to the side wall of the support seat 3 to form a fulcrum. In this embodiment, a first pivot 351 perpendicular to the tip 32 is provided on the outer side of the tip 32. The first pivot 351 and the tip 32 are located at the same horizontal position. The upper end of the connecting handle 3321 is pivoted to the first pivot 351, and the lower end of the connecting handle 3321 is connected to the handle 3322. A second pivot 352 parallel to the first pivot 351 is provided on the support seat 31 at a position corresponding to the intersection of the connecting handle 3321 and the gripping handle 3322. The intersection is pivotally connected to the second pivot 352 to serve as a lever fulcrum.

[0031] In this embodiment, the tip push-pull mechanism 33 further includes a handle limiting structure, which is used to limit the handle 332 to prevent the handle 332 from returning to its original position after the handle 332 pulls the tip 32 back into the installation cavity 311. The handle limiting structure includes a limiting plate support 334 fixed to one end of the support seat 3 away from the reel 10 and a limiting plate 335, one end of the limiting plate 335 support 334 is fixed to the support seat 31, and the other end extends in a direction away from the winding mechanism 1, the lower end of the limiting plate 335 is pivotally connected to the limiting plate 335 support 334, and a hook 336 is provided on the limiting plate 335 for hooking the handle 3322 to prevent it from moving upward, and the horizontal position of the hook 336 corresponds to the position of the handle 3322 when the tip 32 is pulled back into the installation cavity 311. The limiting plate 335 can flip forward or backward. When the pull handle 332 moves downward, the limiting plate 335 flips upward and forward so that its hook 336 hooks the upper part of the pull handle 332. When returning to its original position, the limiting plate 335 flips backward and downward so that the hook 336 leaves the pull handle 332. When the top point 32 is not limited by the pull handle 332 and the limiting plate 335, the restoring force of the spring 331 causes the top point 32 to push outward (toward the reel 10) into the limiting hole 101 of the reel 10.

[0032] The above structure is very convenient for installing the winding mechanism 1, and there is no need to destroy the structure of the winding mechanism 1, punch holes, or use complicated connection methods such as threaded connection. It is only necessary to first press the pull handle 332 downward to retract the end of the winding mechanism 1 (or the rotary drive mechanism 2) away from the installation cavity 311 into the installation cavity 311, and then flip the limit plate 335 upward so that its hook 336 hooks the handle 3322 to prevent the handle 3322 from moving upward and resetting. In this way, the hands of the installer can be freed, so that the installer can better and more conveniently insert the first end of the reel 10 into the limit recess. When the first end of the reel 10 completely falls into the limit groove 213, the second end of the reel 10 is basically aligned with the top 32, and then the limit plate 335 is lowered. At this time, the top 32 can be pushed into the limit hole 101 at the second end of the reel 10 by the restoring force of the spring 331 in the installation cavity 311. It is understandable that in order to make the top 32 better push into the limiting hole 101, the tip is a conical structure, and the limiting hole 101 is also a matching conical hole, and its diameter gradually increases toward the top 32.

[0033] In this embodiment, in order to initially position and support the winding device during installation and facilitate the installer to better install the winding mechanism 1, the disassembly and assembly disk auxiliary mechanism 34 includes a reel support plate 341, a tension spring mounting seat 342, a tension spring 343 and an inclined plate 344 arranged on a support seat 31. The tension spring mounting seat 342 is arranged at the lower end of the support seat 31, the lower end of the tension spring 343 is fixed to the tension spring mounting seat 342, and the upper end is connected to the lower end of the reel support plate 341 away from the reel. The middle part of the reel support plate 341 is pivotally connected to the position corresponding to the reel on the support seat 31 through a pivot, and the upper end is suspended. The upper inclined end of the inclined plate 344 is fixed to the lower end of the support seat 31 and is located directly below the reel, and the lower inclined end has a flat plate extending horizontally forward. When installing the winding mechanism 1, after the staff inserts the first end of the winding mechanism 1 into the limiting groove, the bottom of the winding drum of the winding reel 12 without the lead strip wound can be placed on the reel support plate 341 for rough positioning support, and then the operator loosens the limiting plate 335, and the top 32 is pushed into the limiting hole 101 to complete the installation of the winding mechanism 1. With such a structure, the number of installation personnel can be reduced, and only one installation personnel is needed to install the winding mechanism 1, which saves labor costs and improves installation efficiency.

[0034] In order to facilitate the introduction of the lead strip into the winding drum 12, a lead-introducing mechanism 4 is also included, which is arranged on the back side of the winding mechanism 1. The lead-introducing mechanism 4 includes a sheave support 41 installed on the base 5 and located on the back side of the winding mechanism 1, a sheave assembly 42 installed on the upper end of the sheave support 41, a guide wheel assembly 43 arranged on the sheave assembly 42 and located on the back side of the sheave assembly 42 for introducing the lead strip into the reel, and a positioning guide sleeve 44 arranged on the sheave assembly 42 and located above the sheave assembly 42. The first end of the sheave assembly 42 is connected to the second output end 212 of the reduction box 21 to rotate therewith.

[0035] Both ends of the sheave assembly 42 are respectively mounted on the upper end of the sheave support 41 through bearing seats, and the sheave assembly 42 includes a sheave 421 mounted in two bearing seats and connected to the second output end 212 at the first end, and a sliding ring 422 sleeved on the outside of the sheave 421 and capable of reciprocating along its axial direction when the sheave 421 rotates. The length direction of the sheave 421 is consistent with the length direction of the reel 10, and the positioning guide sleeve 44 and the guide wheel assembly 43 are both arranged on the sliding ring 422.

[0036] The groove wheel 421 is located directly above and behind the winding disk 12, and the length of the groove wheel 421 matches the axial length of the winding disk. A guide groove belt 423 is arranged on the outer circumference of the groove wheel 421 along its length direction. A slider seat 424 is arranged outwardly on the inner circumference of the sliding ring 422, and a slider 425 is fixed in the slider seat 424, and the inwardly protruding end of the slider 425 is inserted into the guide groove belt 423. When the groove wheel 421 rotates, the slider 425 reciprocates in the guide groove belt 423 along the length direction of the groove wheel 421, thereby driving the sliding ring 422 to reciprocate along the length direction of the groove wheel 421, so as to evenly wind the lead strip on the winding disk 12. After adopting this guiding mechanism 4, there is no need for special personnel to guide the lead, which once again reduces the labor cost.

[0037] The guide wheel assembly 43 includes a guide wheel support 431 and a guide wheel 432 (two guide wheels in this embodiment) arranged on the guide wheel support 431. The guide sleeve is a U-shaped structure as a whole. The guide wheel support 431 includes a connecting arm and a guide wheel mounting arm erected on the connecting arm, one end of the connecting arm is fixed to the back of the sliding ring 422 away from the winding disk 12, and the guide wheel is installed on the guide wheel mounting wall, and its axial direction is consistent with the axial direction of the reel 10. The lead strip is wound on the winding disk 12 after passing through the guide wheel and the guide sleeve.

[0038] In this embodiment, the speed ratio between the reel of the winding disk 12 and the groove wheel 421 is i, and the groove wheel 421 travels S1 / 2 for each sliding circle 422, where S1 is the width of the groove wheel, S1=S2*2, where S2 is the width of the sliding circle, and the reel needs to rotate i circles, that is, for each rotation of the reel, the corresponding sliding circle 422 carries the lead strip with a horizontal displacement of m=S1 / 2 / i, where m is approximately equal to the diameter of the lead strip. Therefore, the sliding circle 422 performs a reciprocating motion, and the lead strip is laid on the reel, thereby realizing the lead strip winding.

[0039] It is understandable that in other embodiments, the groove wheel 421 can be changed to a screw rod, a screw rod nut is arranged on the screw rod, the guide sleeve is arranged on the screw rod nut, a guide rod parallel to the screw rod is arranged below the screw rod, a guide sleeve is arranged on the guide rod, and the screw rod nut is connected to the guide sleeve. In this way, the guide sleeve can be moved left and right to evenly wind the lead strip on the winding drum 12.

[0040] When installing the winding mechanism 1 of the winding device of the present invention, the pull handle 332 is first pulled downward to retract the tip 32 into the installation cavity 311, and then the first end of the reel 10 of the winding mechanism 1 is inserted into the first limiting groove. At this time, the winding mechanism 1 is supported by the suspended end of the reel support plate 341 to facilitate the staff to operate the pull handle 332, and then the pull handle 332 is returned to its original position, so that the tip 32 is pushed outward to push into the limiting hole 101 at the second end of the reel 10, and the installation of the winding mechanism 1 is completed. During winding, the groove wheel 421 is driven to rotate by the second output end 212 of the first reduction box 21, so that the sliding ring 422 arranged outside the groove wheel 421 and slidingly matched with the guide groove belt 423 can reciprocate along the length direction of the groove wheel 421, so that the lead strip passing through the guide sleeve on the sliding ring 422 can be reciprocated and evenly wound on the winding disk 12 along the axial direction of the winding mechanism 1, completely replacing manual work and solving the problem of uneven manual winding. When disassembling the winding mechanism, first pull the handle 332 downward to retract the top 32 into the installation cavity 311, and then move the reel 10 toward the second end to disengage from the limiting groove. The winding mechanism 1 with the lead strip rolled on it presses down the suspended end of the reel support plate 341 by its own weight to make it move downward, and the winding mechanism 1 rolls onto the ground with the inclined plate 344, without the need for manual transportation to the ground, saving manpower and facilitating disassembly. The winding device of the present invention replaces the boring manual labor, and can quickly adjust its matching rotation speed according to the size of the discharge speed, which is easy to operate, saving time and labor; the manufacturing cost of the device is low and it can be realized without overly complicated control.

[0041] The above are only implementation modes of the present invention, and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
