The utility model discloses a kind of bundling devices for traditional Chinese medicinal materials, it is related to traditional Chinese medicine bundling technical field, including support frame, machine case and bundling table are installed in order above support frame, machine case inside is hollow, and its bottom and top are kept connection with support frame and bundling table respectively, located on the surface of machine case is installed with binding rope platform, corresponding vertical height with binding rope platform is installed with winding mechanism, winding mechanism is composed of winding ring, wire tube, bracing piece, coil, wherein winding ring is set as open ring and wire tube is connected in symmetry on the bottom of winding ring close to opening position, bracing piece is connected on the bottom of intermediate position of winding ring and penetrates coil, the flower of worm grass is operated by half-automatic operation in the application, so that bundling efficiency is effectively improved, while medicine cartridge can effectively help worker to evenly comb worm grass flower, it is shown by practice that the worm grass flower of the device is more uniform and compact, and the overall appearance and appearance of finished product are also better.

The invention relates to the technical field of pre-oxidized fibers, and particularly discloses a cotton spinning pre-oxidized fiber and a preparation method thereof. The preparation method comprises the following steps: mixing a polyacrylonitrile precursor with a first modified oil agent to obtain a pretreated precursor; the first modified oil agent comprises polytetrafluoroethylene dispersion liquid, nano aluminum oxide and a silane coupling agent; carrying out gradient pre-oxidation on the pre-treated precursor in an air atmosphere under the conditions that the temperature is 215-255 DEG C and the tension is 1650-2100 cN, so as to obtain a pre-oxidized fiber; immersing the pre-oxidized fiber into a second modified oiling agent for oiling and curling to obtain a cotton spinning pre-oxidized fiber; the second modified oiling agent comprises an antistatic agent, a bundling agent and a moisture absorption friction increasing agent. According to the invention, the structural stability and antistatic property of the fiber are improved by controlling the condition parameters of pre-oxidation and optimizing the components and proportion of the first modified oil agent and the second modified oil agent, so that the spinnability of the cotton spinning pre-oxidized fiber is improved, and high-quality and large-scale cotton spinning processing of the pre-oxidized fiber is realized.
