Detailed Implementation

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] Please see Figures 1 to 6This utility model provides a technical solution: a jute carding machine with adjustable spacing, including a carding machine body 1. A mounting plate 2 is fixedly connected to one side of the carding machine body 1. A support frame 3 is installed at the bottom of the mounting plate 2. A support plate 4 is fixedly connected to the bottom of the support frame 3. Brackets 5 are fixedly connected to corresponding sides of the support plate 4. Carding frames 6 are installed at the bottom of the two brackets 5. A convex groove 7 is provided on corresponding sides of the inner side of the carding frame 6. A first convex slider 8 and a second convex slider 9 are slidably connected inside the convex groove 7. A first adjusting frame 10 is fixedly connected between the two first convex sliders 8. A second adjusting frame 11 is fixedly connected between the two second convex sliders 9. A scissor-type telescopic mechanism is provided between the first adjusting frame 10 and the second adjusting frame 11. The frame 12 supports the scissor-type telescopic frame 12. The scissor-type telescopic frame 12 extends as the first adjusting frame 10 and the second adjusting frame 11 push. The scissor-type telescopic frame 12 includes multiple first support rods 121 and multiple second support rods 122. The first support rods 121 and multiple second support rods 122 located on both sides are slidably connected to the first adjusting frame 10 and the second adjusting frame 11, respectively. The multiple first support rods 121 are rotatably connected to the multiple second support rods 122. A support bar 13 is rotatably connected to the cross joint of the first support rods 121 and the second support rods 122. Multiple threaded grooves 14 are opened at the bottom of the support bar 13. Threaded posts 15 are threadedly connected inside the multiple threaded grooves 14. A needle core 16 is fixedly connected to the bottom of the threaded post 15. Through the threaded post 1... 5. The threaded connection with the threaded groove 14 facilitates the installation and removal of the needle core 16. The support frame 3 includes a first frame 31 and a second frame 32. The first frame 31 has multiple threaded holes 33 inside. The corresponding sides of the second frame 32 are respectively rotatably connected to threaded rods 34 and knobs 35. The threaded rods 34 and knobs 35 are fixedly connected. The threaded rods 34 are threadedly connected to one of the threaded holes 33, so that the threaded rods 34 can rotate with the rotation of the knobs 35. Under the action of the threaded connection with the threaded holes 33, it can be fixed with the threaded holes 33 at the required position, which facilitates the installation and removal of the second frame 32 and adjusts the length of the support frame 3 and the height of the comb frame 6. Limiting positions are provided inside the first frame 31 and on one side of the multiple threaded holes 33. Hole 36, the second frame 32 is fixedly connected to a limiting rod 37 on one side of the threaded rod 34. The limiting rod 37 passes through one of the limiting holes 36. The limiting rod 37 is limited by the limiting hole 36, which helps to prevent the second frame 32 from tilting when the knob 35 and the threaded rod 34 are rotated. Inside the comb frame 6, at the bottom of the two convex sliding grooves 7, there are first convex limiting grooves 17 and second convex limiting grooves 18 respectively. Multiple first convex limiting blocks 19 and multiple second convex limiting blocks 20 are slidably connected inside the first convex limiting grooves 17 and the multiple second convex limiting blocks 20 respectively. The multiple first convex limiting blocks 19 and multiple second convex limiting blocks 20 are fixedly connected to both ends of multiple support bars 13 respectively, which facilitates the limiting of multiple support bars 13.One of the convex grooves 7 is rotatably connected to a bidirectional lead screw 21 via a bearing. The bidirectional lead screw 21 passes through one of the first convex sliders 8 and one of the second convex sliders 9, and is threadedly engaged with them. This causes the first and second convex sliders 8 and 9 to rotate with the bidirectional lead screw 21, displacing the first adjusting frame 10 and the second adjusting frame 11. The scissor-type telescopic frame 12 between the first and second adjusting frames 10 and 11 then unfolds, causing multiple support bars 13 at the bottom of the scissor-type telescopic frame 12 to shift equidistantly, facilitating adjustment of the spacing of the cores 16 below the support bars 13. A self-locking motor 22 is installed on one side of the combing frame 6. The self-locking motor 22 is a motor with a locking function. The output end of the self-locking motor 22 is fixedly connected to one end of the bidirectional lead screw 21 via a coupling, providing power for the rotation of the bidirectional lead screw 21. A controller 24 is installed on the outer wall of the combing machine body 1, and a conveyor belt assembly 23 is installed inside the combing machine body 1, located at the bottom of the combing frame 6.

[0018] In summary, when using this jute carding machine with adjustable spacing, the threaded rod 34 and the limiting rod 37 on one side of the second frame 32 are inserted into the threaded holes 33 and the limiting holes 36 at the desired positions in the first frame 31, respectively. The threaded rod 34 is rotated by the fixed connection of the knob 35 to the threaded rod 34, thus fixing the second frame 32. The carding frame 6 below the second frame 32 is positioned above the conveyor belt assembly 23. At this time, the self-locking motor 22 drives the bidirectional lead screw 21 in the convex groove 7 inside the carding frame 6 to rotate. Since the bidirectional lead screw 21 is threadedly connected to the first convex slider 8 and the second convex slider 9, it drives the first convex slider 8 and the second convex slider 9 to rotate. The displacement of the first adjusting frame 10 and the second adjusting frame 11 on the side pushes the scissor-type telescopic frame 12 between the first adjusting frame 10 and the second adjusting frame 11 to extend. Similarly, since multiple cross nodes inside the scissor-type telescopic frame 12 are connected to support bars 13, the multiple support bars 13 are displaced at equal intervals, adjusting the spacing of the needle cores 16 at the bottom of the multiple support bars 13. When it is necessary to replace a single needle core 16, rotate the needle core 16. Through the threaded connection between the threaded post 15 at the top of the needle core 16 and the threaded groove 14 at the bottom of the support bar 13, the threaded post 15 rotates and separates from the threaded groove 14, disassembling the needle core 16. Then, reverse the operation to install a new needle core 16.

[0019] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
