Description

Technical Field

[0001] This application relates to the field of ramie carding technology, and in particular to a ramie carding machine. Background Technology

[0002] Ramie is a natural fiber crop unique to my country, commonly known as "Chinese grass," and is a perennial herbaceous plant. Currently, ramie cultivation is mainly concentrated in my country, accounting for over 90% of the world's planting area and output. In the ramie processing, a ramie carding machine is required to comb the ramie fibers.

[0003] A search revealed that CN217997439U discloses a ramie carding machine. When ramie slivers are fed into the carding box through one feed inlet, they are conveyed to the outer surface of the cylinder by two conveying rollers on the same side. The cylinder performs carding on the ramie slivers. During carding, shorter fibers break and fall off. A fan blows the fallen fibers to the bottom of the carding box. At the same time, two conveying rollers on the other side send the carded ramie slivers out through another feed inlet. The fibers that fall to the bottom of the carding box are then pumped through two pipes from the inside of the carding box to the inside of the collection box for collection.

[0004] Regarding the aforementioned technologies, the inventors believe that the following technical defects exist and require improvement:

[0005] The fibers on the cylinder are carried to the working area of ​​the cylinder and doffer, where they are further combed. Some fibers are transferred to the doffer. The design of the cylinder usually takes into account the arrangement of the needles and the material of its surface. However, ramie may indeed become entangled on the surface of the cylinder of the ramie carding machine during the carding process, thereby reducing the carding efficiency. Utility Model Content

The stepper motor 63 is installed on the outer side of the sliding frame 62. The locking gear 64 is sleeved on the outer side of the output end of the stepper motor 63. The rack seat 65 is installed on the inner side of the arc-shaped bracket 61 and meshes with the outer teeth of the locking gear 64.

[0042] The lifting assembly 5 includes a hollow plate 51, an electric telescopic rod 52, an adjusting plate 53, and a horizontal frame 54. The hollow plate 51 is fixedly connected to the outside of the sliding frame 62. The electric telescopic rod 52 is installed on the inside of the hollow plate 51. The adjusting plate 53 is fixedly connected above the output end of the electric telescopic rod 52. The horizontal frame 54 is installed on the top of the adjusting plate 53 and fixedly connected to the bottom of the embedded pin teeth 4.

[0043] The embedded needle teeth 4 are provided in several groups, and the several groups of embedded needle teeth 4 are arranged at equal intervals inside the tooth gap of the rotating cylinder 3.

[0044] The impurity separation assembly 7 includes a support frame 71, a push cylinder 72, a connecting frame 73, and a needle roller 74.

[0047] A fine toothed roller 13 is also rotatably connected to the side of the combing platform 1 near the U-shaped frame 81.

[0048] The usage process of the ramie carding machine in this embodiment is roughly as follows:

[0049] One end of the ramie fiber wound on the unwinding roller 2 is removed. Then, the DC motor 14 on the outside of the rotating cylinder 3 is started to drive the rotating cylinder 3. The rotating cylinder 3 straightens and evenly cuts the ramie fiber by combing and peeling it. During this process, the stepper motor 63 on the inside of the combing platform 1 can be started simultaneously. Its motor shaft drives the locking gear 64 to rotate. Under the meshing transmission of the locking gear 64 and the rack seat 65, the outer sliding frame 62 can slide back and forth along the outer surface of the arc-shaped support 61. At the same time, the electric telescopic rod 52 on the inside of the hollow plate 51 can be started to push the adjusting plate 53. The adjusting plate 53 drives the upper horizontal frame 5 4. The embedded needles 4 move upward and approach the rotating cylinder 3, so that the embedded needles 4 can be embedded inside the gaps between the sharp teeth of the rotating cylinder 3. Under the effect of repeated rotation, the short fibers hooked inside the sharp teeth of the rotating cylinder 3 are cleared out. Then, the suction fan 9 is turned on, and the cleaned short fibers can be sucked in through the suction pipe 10 and discharged into the material box 12 through the discharge pipe 11 for subsequent collection. On the other hand, the push cylinder 72 above the electrically started support frame 71 pushes the connecting frame 73. The connecting frame 73 drives the bottom needle roller 74 to approach the rotating cylinder 3. The fine needles on the needle roller 74 touch the surface of the rotating cylinder 3, thereby removing the impurities embedded in the sharp teeth of the rotating cylinder 3. After carding, the ramie is output along the outside of the rotating cylinder 3 and passes through a single set of fine tooth rollers 13 to complete the impurity re-cleaning effect. At the same time, the stepper motor 82 is started to wind the carded ramie onto the take-up roller 83, completing the carding and synchronous winding effect.

[0050] The beneficial technical effects of the ramie carding machine according to the embodiments of this application are roughly as follows:

[0051] The impurity separation component 7 removes impurities such as dust and grass clippings embedded in the cylinder teeth, ensuring fiber purity, which is crucial for subsequent processing and the quality of the final product. The embedded needle teeth 4 cleverly solve the short fiber problem. It removes short fibers hooked inside the rotating cylinder teeth 3, preventing their accumulation and interference during the combing process and ensuring combing effectiveness. The lifting component 5 engages with the embedded needle teeth 4 and abuts them against the inner side of the gap between the rotating cylinder teeth 3. This design allows the equipment to adjust according to the type and state of the fibers to achieve the best combing effect.

[0052] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
