DETAILED DESCRIPTION

[0039] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0040] See also Figure 1-4 The utility model provides a technical solution: a wool opening mechanism for loosening wool before feeding the wool into an opener, comprising:

[0041] A machine body 1 and a conveying device 2 connected to the machine body 1 and used for conveying wool, wherein the conveying device 2 has a conveying surface for placing the wool;

[0042] The opening mechanism further comprises at least one loosening assembly for loosening the wool, the loosening assembly comprising:

[0043] a bowstring 20 provided at the upper end of the conveying surface;

[0044] A rotating body 14 and an elastic bar 16 provided on the outside of the rotating body 14;

[0045] A driving component for driving the rotating body 14 to rotate, thereby driving the elastic bar 16 to intermittently drag the bowstring 20 to cause it to elastically deform, thereby imparting a vibrating elastic force to the bowstring 20;

[0046] The above technical solution can be used to loosen the wool before feeding it into the opener. When in use, the wool is placed on the conveying surface of the conveying device 2, and the conveying device 2 feeds the wool to the feeding port of the opener. When the wool passes directly under the bowstring 20, the driving component drives the rotating body 14 to rotate, thereby driving the elastic bar 16 on the surface of the rotating body 14 to intermittently drag the bowstring 20 to cause it to undergo elastic deformation, thereby giving the bowstring 20 a vibrating elastic force. When the elastic bar 16 is separated from the bowstring 20, the bowstring 20 is ejected onto the wool, thereby breaking up the wool. The breaking process is also beneficial to separate hard impurities in the wool, such as gravel, agglomerated soil particles, etc., so that the wool can be pre-loosened before entering the opener.

[0047] like Figure 2 As shown, in this embodiment, an end shaft 17 is provided at one end of the elastic bar 16, and the end shaft 17 is rotatably connected to the inner groove 15 opened in the rotating body 14. A spring 18 is provided in the inner groove 15, and one end of the spring 18 is connected to the elastic bar 16;

[0048] The above technical solution can ensure that the elastic bar 16 can stably pull the bowstring 20, so that the bowstring 20 can undergo elastic deformation and accumulate kinetic energy for the bowstring 20. When the rotating body 14 drives the elastic bar 16 to rotate, the elastic bar 16 collides with the bowstring 20. As the rotating body 14 rotates, the dragging force of the elastic bar 16 on the bowstring 20 will increase. The dragging force will produce a reaction force on the elastic bar 16, thereby compressing the spring 18, and then causing the elastic bar 16 to rotate in the inner groove 15. After the rotation, the elastic bar 16 disengages from the bowstring 20, and the bowstring 20 is ejected onto the wool to break it up.

[0049] like Figure 2 As shown, in this embodiment, the opening mechanism further includes a frame 19 fixedly connected to both ends of the bowstring 20;

[0050] The above technical solution can maintain the tension of the bowstring 20. Since the frame 19 is used to fix the two ends of the bowstring 20, the bowstring 20 is in a taut state, ensuring that the bowstring 20 can hit the wool powerfully.

[0051] like Figure 4 As shown, in this embodiment, the opening mechanism also includes a clamping assembly for fixing the frame 19, and the clamping assembly includes at least two clamping parts to fix the two ends of the frame 19; specifically, the clamping part includes: a first fixed clamping plate 22 connected to the machine body 1 at one end; a first movable clamping plate 23, one end of which is slidably matched with a slide groove 25 provided in the first fixed clamping plate 22, and a clamping space for clamping the frame 19 is formed between the first fixed clamping plate 22 and the first movable clamping plate 23; a threaded rod 26 rotatably provided in the slide groove 25 at one end, and the threaded rod 26 is matched with a threaded groove 27 provided in the first movable clamping plate 23; a positioning protrusion 24 is provided at the upper end of the first fixed clamping plate 22, and the positioning protrusion 24 is engaged with the positioning hole 21 provided in the frame 19;

[0052] The above technical solution can facilitate the disassembly of the frame 19 and the bowstring 20. When the bowstring 20 is aged or broken, a new bowstring 20 needs to be replaced. At this time, the handle at the outer end of the threaded rod 26 is rotated to drive the threaded rod 26 to rotate. The threaded rod 26 cooperates with the threaded groove 27 to drive the first movable splint 23 to rise, and the first movable splint 23 is fully separated from the first fixed splint 22. At this time, the positioning hole 21 of the frame 19 can be pulled out from the positioning protrusion 24 at the upper end of the first fixed splint 22 to complete the disassembly. Then, the positioning hole 21 on the surface of the new frame 19 is aligned with the positioning protrusion 24 and inserted. The threaded rod 26 is rotated to drive the first movable splint 23 and the first fixed splint 22 to close together, thereby clamping the frame 19.

[0053] like Figure 1As shown, in this embodiment, a first rotating shaft 13 is provided on the side of the rotating body 14, and the body 1 is provided with a support structure for rotatably connecting to the first rotating shaft 13; specifically, the support structure includes: a second fixed clamping plate 8 connected to the body 1 at one end; a second movable clamping plate 9 hingedly connected to the second fixed clamping plate 8, a rotating groove 10 for limiting the first rotating shaft 13 is defined between the second fixed clamping plate 8 and the second movable clamping plate 9, a bolt hole 12 is defined at one end of the second fixed clamping plate 8 and the second movable clamping plate 9; and a bolt 11 is disposed in the bolt hole 12;

[0054] The above technical solution can facilitate the disassembly of the rotating body 14. When maintenance of the rotating body 14 is required, the bolt 11 is unscrewed from the bolt hole 12, and the second movable clamping plate 9 is rotated to disengage it from the first rotating shaft 13, so that the first rotating shafts 13 at both ends of the rotating body 14 can be removed from the rotating groove 10.

[0055] like Figure 1 As shown, in this embodiment, the loosening mechanism further includes: a hopper 3 provided with a discharge chute 4; a second rotating shaft 5 rotatably provided on the machine body 1; a plurality of levers 6 provided on the outer circumferential surface of the second rotating shaft 5, the levers 6 extending into the discharge chute 4 and contacting the wool inside the hopper 3; a driving motor 7 provided on one side of the machine body 1, the output shaft of the driving motor 7 being connected to the second rotating shaft 5; a driving component including: a belt pulley 28 provided at one end of the first rotating shaft 13 and the second rotating shaft 5 respectively; a belt 29 sleeved on the two belt pulleys 28;

[0056] The above technical solution can be used to further loosen the wool. Since the wool is tightly bundled before being loosened, it may not be enough to fully loosen it by simply hitting its surface with the bowstring 20. Therefore, a discharge chute 4 is provided at the bottom of the hopper 3. The discharge chute 4 is preferably a strip-shaped hole structure. When the driving motor 7 drives the second rotating shaft 5 to rotate, the second rotating shaft 5 will synchronously drive the lever 6 on its surface to rotate. When the lever 6 rotates, it will partially extend into the discharge chute 4, thereby pulling the wool inside the hopper 3 out of the discharge chute 4. Since the wool passes under the bowstring 20, combined with the bouncing of the elastic strip 16, the wool can be pre-loosened more effectively, and the pulled wool falls onto the conveying surface of the conveying device 2. When the wool passes under the bowstring 20, since the second rotating shaft 5 is connected to the other end of the first rotating shaft 13 through the belt pulley 28 and the belt 29, when the second rotating shaft 5 rotates, it will drive the first rotating shaft 13 to rotate synchronously, and then drive the rotating body 14 and the elastic strip 16 on its surface to pull the bowstring 20, giving the bowstring 20 elastic force, and the bowstring 20 will loosen the wool.

[0057] Working principle: When in use, first start the driving motor 7. When the driving motor 7 drives the second rotating shaft 5 to rotate, the second rotating shaft 5 will synchronously drive the lever 6 on its surface to rotate. When the lever 6 rotates, it will partially extend into the discharge trough 4, thereby pulling the wool inside the hopper 3 out of the discharge trough 4. In this way, combined with the beating of the elastic bar 16, the wool can be pre-loosened more effectively, and the pulled-out wool falls onto the conveying surface of the conveying device 2. When the wool passes under the bowstring 20, since the second rotating shaft 5 is connected to the other end of the first rotating shaft 13 through the belt pulley 28 and the belt 29, when the second rotating shaft 5 rotates, it will drive the first rotating shaft 13 rotates synchronously, thereby driving the rotating body 14 and the elastic strip 16 on its surface to pull the bowstring 20. When the rotating body 14 drives the elastic strip 16 to rotate, the elastic strip 16 conflicts with the bowstring 20. As the rotating body 14 rotates, the dragging force of the elastic strip 16 on the bowstring 20 will increase, and the dragging force will produce a reaction force on the elastic strip 16, thereby compressing the spring 18, and then the elastic strip 16 rotates in the inner groove 15. After the rotation, the elastic strip 16 is separated from the bowstring 20, and the bowstring 20 is ejected onto the wool to break it up. The breaking process is also beneficial to separate hard impurities in the wool, such as gravel, agglomerated soil particles, etc., so that the wool can be pre-loosened before entering the opener.
