Problems solved by technology

[0004] The present invention provides a belt-type rubbing method and device for replacing silk sheaths, which mainly solves the problem of wet raw silk aggregation in silk reeling production in the prior art. The effect of this method is to achieve the aggregation of wet raw silk. The non-uniform structure of the silk sheath between threads brought about by this method affects the quality of raw silk, and the technical problems of complex operation and low labor productivity; The technical problem of uneven aggregation caused by periodic changes

Embodiment 1

[0022] Example 1: In this example, a belt friction method to replace the silk sheath, according to the requirements of raw silk specifications, such as figure 1 , figure 2 , image 3 , A number of cocoon filaments 15 pass through the thread connecting wing 1 and rotate at a high speed to form a wet raw silk 16. The wet raw silk 16 containing a large amount of water passes through the thread collector 2, through the lower guide wire hook 3 and the upper guide wire hook 4, around On the upper and lower two-layer reverse-moving transmission belt 5 that can be used to replace the silk sheath to gather cocoon filaments, a wire-pressing guide roller 21 is arranged in the middle of the upper and lower two-layer reverse-moving transmission belts to counter the wet raw silk 16 wound on the transmission belt. Play the role of compacting and increasing the wrap angle. The wet raw silk and the transmission belt move relative to each other. When the transmission belt is driven at a constant...

Embodiment 2

[0026] Example 2: A belt friction device that replaces the silk sheath in this example, such as Figure 4 , The transmission belt 5 is located on the outside of the wet raw silk 16, and the thread pressing guide roller is located on the inside of the wet raw silk 16, and the rest is the same as in embodiment 1.

Abstract

The invention relates to a silk reeling method and a silk reeling device, in particular to a band friction method and a band friction device for replacing a silk sheath. The method and the device mainly solve the technical problems that a wet raw silk gathering method during silk reeling production in the prior art forms a silk sheath structure by adopting a manual mode, and gathers wet raw silk through a silk sheath effect, and the quality of the raw silk is influenced, operation is complicated, and labor productivity is low due to the nonuniformity of the silk sheath structure between threads brought by the method, or solve the technical problem that gathering is nonuniform due to periodical change of the speed when back-and-forth friction is conducted by adopting reciprocating movement. According to the method and the device, upper and lower layers of driving bands which can be used for replacing silk sheath gathering cocoon silk and move reversely are wound with the wet raw silk; silk pressing guide rolls are arranged between the driving bands; a winding movement direction of the wet raw silk is perpendicular to movement directions of the driving bands relative to the raw silk; friction is generated between the wet raw silk and the driving bands; and tiny sections on the surface of the cocoon silk can be removed after rotation and kneading.

Description

Technical field [0001] The invention relates to a silk reeling method and device, in particular to a belt friction method and device that replaces the silk sheath. Background technique [0002] In the silk reeling process, the thread of the cocoon under the thread in the reeling process cannot be directly wound into shape after being collected by the thread collector. This is because: (1) The cocoon filaments that make up the raw silk during the silk reeling process contain a lot of moisture. If they are directly wound into shape, not only is it difficult to dry, which affects the color of the silk, but also the sericin glues to each other to form a hard rubber sheet. When re-shaking into a skein, the thread is not easy to unwind, and it is easy to cause cutting. (2) The multiple cocoon filaments that make up the raw silk are loosely bonded to each other and fail to be tightly held together. Such filaments have poor strength and are easy to split. (3) There are still various ti...
