Specific implementation mode

[0024] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] To further understand the content of the present utility model, the present utility model will be described in detail with reference to the accompanying drawings.

[0026] Please refer to Figures 1-4 , the present utility model provides a technical solution: a needle plate rack for a needle-punched non-woven fabric production line, including two support frames 1. Two support legs 15 are fixedly installed at the bottom of the two support frames 1. Rotating wheels 16 are rotatably connected inside the four support legs 15. Fixing frames 17 are fixedly installed on the opposite sides of the two support frames 1. Connecting rods 18 are slidably connected inside the two fixing frames 17. The two connecting rods 18 are arranged in a cross shape. The other ends of the two connecting rods 18 are respectively rotatably connected to the two support frames 1. A bolt is rotatably connected inside one of the fixing frames 17. The surface of the bolt is threadedly connected to one end of a connecting rod 18.

[0027] Rotate the bolt to make the connecting rod 18 on one side slide inside the fixing frame 17, thereby adjusting the distance between the two support frames 1.

[0028] Slideways 4 are opened on the opposite sides of the support frames 1. Sliders 11 are slidably connected inside the two slideways 4. Collecting hoppers 2 are fixedly installed on the two sliders 11. Connecting plates 3 are slidably connected inside the two collecting hoppers 2. The shapes of the two sliders 11 are both T-shaped.

[0029] When the two support frames 1 move away from each other, the two sliders 11 will be pulled to move away from each other, thereby making the two collecting hoppers 2 slide on the connecting plate 3, so as to facilitate adjusting the width of the two collecting hoppers 2 according to the distance between the two support frames 1, which is convenient for the user to use.

[0030] A rotating shaft 5 is rotatably connected to the inside of each of the two support frames 1. A pulling rope 6 is wound around the surface of each of the two rotating shafts 5. The lower ends of the two pulling ropes 6 are fixedly connected to the two sliders 11 respectively. The two rotating shafts 5 both rotatably penetrate through the support frames 1 and extend to the outside of the two support frames 1. A rotating handle 10 is fixedly installed at one end of each of the two rotating shafts 5 extending to the outside of the support frames 1.

[0031] Rotate the rotating handle 10 to drive the rotation of the rotating shaft 5, so that the pulling rope 6 is wound around the rotating shaft 5, and then pull the slider 11 to slide inside the slideway 4, so as to facilitate the adjustment of the heights of the two collection hoppers 2 and the connecting plate 3, and facilitate the adjustment according to the usage requirements, so as to facilitate the collection of broken needles and improve the convenience of broken needle collection.

[0032] A fixed box 7 is fixedly sleeved on each of the two rotating shafts 5. The two fixed boxes 7 are both fixedly connected to the support frames 1. A ratchet 12 is fixedly sleeved on one end of each of the two rotating shafts 5 located inside the two fixed boxes 7. A rotating rod 9 is rotatably connected to the inside of each of the two fixed boxes 7. A ratchet pawl 13 is fixedly sleeved on each of the two rotating rods 9. The two ratchet pawls 13 are respectively engaged with the two ratchets 12. A torsion spring 14 is movably sleeved on each of the two rotating rods 9. One end of each of the two torsion springs 14 close to the two ratchet pawls 13 is fixedly connected to the two ratchet pawls 13 respectively. One end of each of the two torsion springs 14 away from the two ratchet pawls 13 is fixedly connected to the inner wall of the two fixed boxes 7 respectively. The two rotating rods 9 rotatably penetrate through the fixed boxes 7 and extend to the outside of the fixed boxes 7. A handle 8 is fixedly installed at one end of each of the two rotating rods 9 extending to the outside of the fixed boxes 7.

[0033] When rotating the rotating handle 10, the rotating shaft 5 rotates, and then the rotating shaft 5 drives the ratchet 12 to rotate, so that the ratchet 12 presses the ratchet pawl 13, and then the rotating rod 9 rotates inside the fixed box 7, so that the torsion spring 14 deforms. Then when the ratchet pawl 13 coincides with another ratchet tooth, the ratchet pawl 13 will be reset by the torsion of the torsion spring 14, so as to fix the ratchet 12, and then fix the rotating shaft 5, so as to facilitate the fixing of the height to which the collection hopper 2 is raised.

[0034] Working principle:

[0035] Rotate the rotary handle 10 to drive the rotation of the rotating shaft 5, causing the pulling rope 6 to wind around the rotating shaft 5, and then pulling the slider 11 to slide inside the slideway 4, thereby facilitating the adjustment of the heights of the two collecting hoppers 2 and the connecting plate 3. When rotating the rotary handle 10, the rotating shaft 5 rotates, and then the rotating shaft 5 drives the ratchet wheel 12 to rotate, causing the ratchet wheel 12 to squeeze the pawl 13, and then causing the rotating rod 9 to rotate inside the fixed box 7, causing the torsion spring 14 to deform. Then, when the pawl 13 coincides with another ratchet tooth, the pawl 13 will be reset by the torsion force of the torsion spring 14, thereby fixing the ratchet wheel 12, and then fixing the rotating shaft 5, thereby facilitating the fixing of the height to which the collecting hopper 2 is raised.

[0036] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
