[0038] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0039] like Figures 1 to 6As shown, the utility model provides a spunbond nonwoven fabric winding mechanism, including an L-shaped bottom plate 1 and a vertical rod 14 fixedly arranged on the upper end of the bottom plate 1, a protrusion on one side of the upper end of the vertical rod 14 is fixed to the mounting end of the servo motor 6 by screws, the output shaft of the servo motor 6 is fixedly connected to the connecting shaft 16 by a coupling, a bearing is embedded in the upper end of the vertical rod 14 and the upper end of the vertical rod 14 is in a through state, the connecting shaft 16 is inserted into the inner ring of the bearing and is interference fit, one end of the connecting shaft 16 is fixed to the fixed end of the electromagnetic clutch 2 18 by screws, the movable end of the electromagnetic clutch 2 18 is fixed to the mounting plate 19 by screws, and the mounting plate 19 is away from the bottom plate 1. The surface of the side of the mounting plate 19 is equally spaced and surrounded by a first winding assembly 2, a second winding assembly 3, a third winding assembly 4 and a fourth winding assembly 5;

[0040] The first winding component 2 includes a main bearing 22 embedded in the mounting disk 19, and the main shaft 28 is inserted into the inner ring of the main bearing 22 and has an interference fit. The end face of the main bearing 22 facing the winding roller 21 is flush with the end face of the mounting disk 19, so that the end face of the winding roller 21 abuts against the end face of the mounting disk 19, and the end of the main shaft 28 away from the bottom plate 1 is movably connected with the winding roller 21 for winding and winding. A plurality of steel needles are fixedly provided on the surface of the winding roller 21, and the length of the steel needles is set at 0.2mm~0.5mm, which can be pasted with non-woven fabrics, and each steel needle is provided with a barb, which is similar to the barb of a fish hook.

[0041] The above structural action can realize the winding and reeling of the nonwoven fabric without stopping the device. The wound reel 21 can be rotated to the collection position, and a new reel 21 can be reeled, thereby improving the working efficiency of the winding device.

[0042] The main shaft 28 is located at one end of the bottom plate 1 and is fixed to the fixed end of the electromagnetic clutch 24. The first winding assembly 2, the second winding assembly 3, the third winding assembly 4 and the fourth winding assembly 5 have the same structure and size except that the length of the main shaft 28 is different. The toothed rings on the outer side of the movable end of the electromagnetic clutch 24 of the first winding assembly 2, the second winding assembly 3, the third winding assembly 4 and the fourth winding assembly 5 are respectively engaged with different toothed rings 17 on the surface of the connecting shaft 16 through a toothed belt 23. The main shaft 28 is located on one side of the bottom plate 1 and is fixed with four toothed rings 17 respectively adapted to the first winding assembly 2, the second winding assembly 3, the third winding assembly 4 and the fourth winding assembly 5. The arrangement method (such as Figure 4 As shown), the four toothed belts 23 of the first winding assembly 2, the second winding assembly 3, the third winding assembly 4 and the fourth winding assembly 5 are arranged in an array, and a fixing ring for limiting the toothed belt 23 is fixed between the two gear rings 17 (as shown in FIG. Figure 4 shown).

[0043] Because the electromagnetic clutch 2 18 is in the power-off state, the mounting disk 19 does not rotate, and the connecting shaft 16 drives the four gear rings 17 to rotate, and the gear ring 17 drives the electromagnetic clutch 1 24 of the third winding component 4 to rotate through the toothed belt 23. Because the electromagnetic clutch 1 24 of the third winding component 4 is controlled by the controller and energized, the two movable ends are connected as a whole to realize power transmission, thereby driving the main shaft 28 to rotate rapidly in the inner ring of the main bearing 22, and the main shaft 28 drives the winding roller 21 of the third winding component 4 to rotate through the cross rod 25, thereby winding the non-woven fabric.

[0044] A cross rod 25 is fixedly provided at the middle of one end of the main shaft 28 away from the electromagnetic clutch 24. The cross rod 25 is provided with an inclined surface inclined toward the axis of the cross rod 25 on one side of the fastening nut 27 to facilitate the insertion of the winding roller 21 onto the cross rod 25. A cross groove 26 is provided in the middle of the winding roller 21 for movably interlacing with the cross rod 25. The inner wall of the cross groove 26 abuts against the surface of the cross rod 25 to form a clearance fit. The end of the cross rod 25 is located at the inner opening of the cross groove 26, and a threaded rod fixed at the middle of one end of the cross rod 25 is screwed with a fastening nut 27 abutting against the end face of the winding roller 21. A handle for easy rotation is fixed on the surface of the fastening nut 27, and the fastening nut 27 fixes the winding roller 21.

[0045] The user removes the fastening nut 27, and then uses a forklift or other tool to pull out the winding roller 21 from the cross-shaped rod 25, and then inserts a new winding roller 21 to install and fasten it with the fastening nut 27 to complete the cycle.

[0046] Specifically, a bracket 11 is fixedly provided on one side of the base plate 1 at the laser cutter 10. The bracket 11 is arranged between the non-woven fabric production equipment and the mounting plate 19. The bracket 11 is rotatably arranged with a rotating shaft in the middle of the guide roller 12. The end face of one end of the guide roller 12 is flush with the end face of the mounting plate 19.

[0047] The bracket 11 props up the guide roller 12, and the staff passes the non-woven fabric through the upper end of the guide roller 12 and then fixes it on the upper end of the winding roller 21 of the third winding component 4. The non-woven fabric is fixed by passing several steel needles on the surface of the winding roller 21 through the non-woven fabric. When the winding roller 21 of the fourth winding component 5 contacts the non-woven fabric, the steel needles on its surface are inserted into the non-woven fabric, and the barbs limit the non-woven fabric to avoid separation. The linear drive mechanism 29 receives the signal and is energized. The active end of the linear drive mechanism 29 quickly drives the laser cutter 10 to quickly cut the non-woven fabric on the lower end surface of the winding roller 21 of the fourth winding component 5. It should be noted that the position for cutting the non-woven fabric is a position that does not contact the steel needles.

[0048] Furthermore, a linear drive mechanism 3 13 is fixedly provided on the upper end of the base plate 1 near the bracket 11, and a support rod 8 is fixedly provided on the movable end of the linear drive mechanism 3 13, and a linear drive mechanism 2 9 is fixedly provided on the side of the support rod 8 facing the mounting disk 19. The movable end of the linear drive mechanism 2 9 can move a distance greater than the length of the winding roller 21. In order to enable the laser cutter 10 to completely cut the non-woven fabric, the movable end of the linear drive mechanism 2 9 is fixed to the mounting end of the laser cutter 10, and the laser cutter 10 is located directly below the winding roller 21 when cutting the non-woven fabric.

[0049] The movable end of the linear drive mechanism three 13 drives the support rod 8 to move, thereby driving the laser cutter 10 through the linear drive mechanism two 9 to move to just below the expected moving position of the winding roller 21 of the fourth winding assembly 5. Subsequently, the linear drive mechanism one 71 receives the signal and is energized, and its movable end drives the limit tooth 72 to move downward and separate from the limit groove 15 of the mounting disk 19, thereby making the mounting disk 19 in a movable state.

[0050] Furthermore, a limiting mechanism 7 is fixedly provided at the upper end of the base plate 1 below the mounting disk 19. The limiting mechanism 7 includes a linear driving mechanism 71 fixedly provided at an oblique lower portion of the mounting disk 19. A limiting tooth 72 for limiting is fixedly provided at the movable end of the linear driving mechanism 71. A plurality of limiting grooves 15 that fit with the limiting teeth 72 are provided around the surface of the mounting disk 19.

[0051] The movable end of the linear drive mechanism 71 drives the limit tooth 72 to move upward, so that the limit tooth 72 is inserted into the limit groove 15 of the mounting disk 19, and the mounting disk 19 is fixed to prevent the mounting disk 19 from shaking when the non-woven fabric is rolled up, thereby affecting the flatness of the rolling.

[0052] The nonwoven fabric is always wound around the winding roller 21 directly below the mounting plate 19, and the nonwoven fabric is in contact with the upper end of the guide roller 12. Figure 1 shown.

[0053] Among them, the servo motor 6, the electromagnetic clutch 1 24, the electromagnetic clutch 2 18, the linear drive mechanism 1 71, the linear drive mechanism 2 9, the laser cutter 10 and the linear drive mechanism 3 13 are all prior art, and their structural principles are not described in detail. At the same time, the device also includes a compiler, a switch, a power supply and other devices adapted to the servo motor 6, which are not described in detail because they are not the main technology. After the assembly of this device is completed, it needs to be debugged to work without stopping. The laser cutter 10 is matched with a numerical control system, a voltage-stabilized power supply and other devices.

[0054] Principle and process of this utility model:

[0055] The device has three working steps: Step 1, the reel 21 rotates to wind the non-woven fabric; Step 2, the reel 21 after collection is rotated to replace it; Step 3, while the new reel 21 rotates, the laser cutter 10 cuts the non-woven fabric; the details are as follows:

[0056] Step 1: The staff passes the nonwoven fabric through the upper end of the guide roller 12 and then fixes it on (such as Figure 1 The upper end of the winding roller 21 of the third winding assembly 4 is fixed by passing a plurality of steel needles on the surface of the winding roller 21 through the non-woven fabric. Then, the staff turns on the switch and transmits the signal to the servo motor 6 through the compiler. The output shaft of the servo motor 6 drives the connecting shaft 16 to rotate through the coupling, and the connecting shaft 16 drives one end of the electromagnetic clutch 18 to rotate;

[0057] It should be noted that, except for the third winding assembly 4, the first winding assembly 2, the second winding assembly 3, the fourth winding assembly 5 and the electromagnetic clutch 2 18 are all in the power-off state, and the two ends of the electromagnetic clutch 2 18 and the electromagnetic clutch 1 24 can rotate freely;

[0058] Because the electromagnetic clutch 2 18 is in the power-off state, the mounting disk 19 does not rotate, and the connecting shaft 16 drives the four gear rings 17 to rotate, and the gear ring 17 drives the electromagnetic clutch 1 24 of the third winding component 4 to rotate through the toothed belt 23. Because the electromagnetic clutch 1 24 of the third winding component 4 is controlled by the controller and energized, the two movable ends are connected as a whole to realize power transmission, thereby driving the main shaft 28 to rotate rapidly in the inner ring of the main bearing 22, and the main shaft 28 drives the winding roller 21 of the third winding component 4 to rotate through the cross rod 25, thereby winding the non-woven fabric.

[0059] Step 2, when the winding roller 21 of the third winding assembly 4 is about to be wound, the electromagnetic clutch 2 18 is energized to transmit the force of the servo motor 6, and the output shaft of the servo motor 6 drives the connecting shaft 16 and the electromagnetic clutch 2 18 to rotate, so that the mounting plate 19 rotates a certain angle, which needs to be determined according to the number of winding assemblies set. The ultimate goal is to make the winding roller 21 of the fourth winding assembly 5 contact with the non-woven fabric. During this process, the winding roller 21 of the third winding assembly 4 is still rotating;

[0060] Step 3, before the mounting plate 19 rotates, the controller transmits signals and electricity through the wires to make the linear drive mechanism 3 13 work, and the movable end of the linear drive mechanism 3 13 drives the support rod 8 to move, thereby driving the laser cutter 10 to move to the right below the expected moving position of the winding roller 21 of the fourth winding assembly 5 through the linear drive mechanism 2 9. Since the angles and positions of these movements are pre-set, they can be moved accurately. Subsequently, the linear drive mechanism 1 71 receives the signal and is energized, and its movable end drives the limit tooth 72 to move downward and separate from the limit groove 15 of the mounting plate 19, so that the mounting plate 19 is in a movable state;

[0061] When the winding roller 21 of the fourth winding component 5 contacts the non-woven fabric and the steel needle on its surface is inserted into the non-woven fabric, the barb limits the non-woven fabric to prevent separation, and the linear drive mechanism 29 receives the signal and is energized. The active end of the linear drive mechanism 29 quickly drives the laser cutter 10 to quickly cut the non-woven fabric on the lower end surface of the winding roller 21 of the fourth winding component 5. It should be noted that the position for cutting the non-woven fabric is a position that does not contact the steel needle. After the cutting is completed, the electromagnetic clutch 24 of the fourth winding component 5 is immediately energized, and the operation of "step one" is repeated to wind up the non-woven fabric.

[0062] At the same time, the electromagnetic clutch 24 of the third winding assembly 4 is powered off after a delay of 0.5 seconds, so that the winding roller 21 of the third winding assembly 4 loses power, and the excess non-woven fabric can be wound around the winding roller 21 in 0.5 seconds to complete the winding;

[0063] Afterwards, the movable end of the linear drive mechanism 3 13 drives the laser cutter 10 to move to the original position to avoid interference with the subsequent winding roller 21 .

[0064] With the continuous winding and wrapping, the winding roller 21 of the first winding will move to a higher place. At this time, the user removes the fastening nut 27, and then uses a forklift or other tools to pull the winding roller 21 out of the cross rod 25, and then inserts a new winding roller 21 to install and fasten it through the fastening nut 27 to complete the cycle.

[0065] By repeating the above "step one, step two, step three", the device can wind and reel the non-woven fabric without stopping. The wound reel 21 can be rotated to the collection position, and a new reel 21 can be used for winding, thereby improving the working efficiency of the winding device.

[0066] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
