Description

A Wet Raw Silk Aggregation Method and Special Device

technical field

The invention relates to a silk reeling method and device, in particular to a method for gathering raw silk in a wet state and a special device.

Background technique

In the silk reeling process, after the threads of the cocoons in the silk reeling are collected by the thread collecting device, they cannot be directly wound into shape. This is because: (1) During the silk reeling process, the cocoon silk strips that make up the raw silk contain a lot of water. If they are directly wound and formed, not only is it not easy to dry, but it will affect the color of the silk, and the sericin is glued to each other to form a hard glue silk sheet. When reshaping into skeins, the thread is not easy to unwind, and it is easy to cause cutting. (2) The multiple cocoon threads that make up raw silk are loosely bonded to each other and cannot be tightly entangled. Such threads are weak in strength and easy to split. (3) There are still various tiny knots on the surface of the cocoon silk after passing through the thread collector, and these knots should be eliminated or reduced as much as possible before winding. Therefore, in the silk reeling process, it is necessary to use the artificial twisting sheath method to form a silk sheath for wet raw silk containing a large amount of moisture.

For a long time, the silk sheath used in silk reeling has been manually operated. The cocoon silk thread passed through the thread collector is wound around the upper drum and the lower drum. Formed by positioning the drum. Through the high-speed rotation, mutual extrusion and friction of the two sections of the silk sheath, it can diverge the moisture of the wet raw silk strips, strengthen the aggregation and cohesion of each cocoon between the raw silks, and remove some small knots. After the action of the silk sheath It reduces the moisture content of the raw silk, enhances the cohesion of the silk sliver, improves the roundness of the raw silk and the smoothness of the sliver surface. Due to the manual operation to form the silk sheath structure, the length and shape of the silk sheaths formed by different silk reelers or the same silk reeler will be different each time, and the functions of different silk sheaths will be different. Affect raw silk quality. More importantly, this traditional silk reeling process that relies on manual operations seriously restricts the improvement of labor productivity in silk reeling.

Contents of the invention

The present invention provides a wet-state raw silk gathering method and a special device, which mainly solves the wet-state raw silk gathering method existing in the prior art in silk reeling production. The silk sheath structure is formed manually, and the function of the silk sheath To achieve the aggregation of raw silk in wet state, the non-uniform silk sheath structure between threads brought by this method affects the quality of raw silk, and the technical problems of complicated operation and low labor productivity.

Above-mentioned technical problem of the present invention is mainly solved by following technical scheme:

A method for gathering raw silk in a wet state according to the present invention, said method comprising: after the cocoon silk containing a large amount of water passes through the threading wing and the thread collector, passes through the lower guide wire hook, and then winds on a guide wire that can be used for gathering raw silk in a wet state. On the silk roll, the winding movement direction of the wet raw silk is perpendicular to the moving direction of the godet roller relative to the raw silk. The wet raw silk and the godet roll reciprocate in a straight line relative to each other. When the godet roller touches, it can be dried to reduce the moisture content of the raw silk. The wet raw silk rubs against the godet roller, and the surface of the cocoons that make up the wet raw silk is covered with sericin. The sericin is rubbed around the raw silk, so that the wet raw silk gathers tightly; at the same time, due to the friction between the godet roller and the raw silk, the silk sliver rotates, and the upper and lower sections of the silk sliver that are in contact with the godet roller rotate in different directions. The raw silk goes around the godet roller and then rotates in the opposite direction. In this way, the raw silk obtained after passing through the upper guide hook does not rotate, and the raw silk with the same characteristics as the traditional processing technology is maintained. During this rotation, the moisture in the silk sliver Distributed due to extrusion, and the tiny knots on the surface of the cocoon silk can be eliminated after being rotated and rubbed.

The godet roller of the invention can rotate slowly, actively drives the wet raw silk to move during the rotation, and plays the role of actively feeding the wire to reduce the tension of the thread and increase the elongation of the wet raw silk. The raw silk processed by this method has the advantages of smooth surface, round cross section, good elongation and tight cohesion.

After adopting the technology of the present invention, it can be realized that the wet raw silk of each thread maintains the same twisting result, and the obtained silk sliver also has the same quality, which eliminates the quality difference of each thread sliver caused by manual operation in the past.

There are several small holes with a diameter of 3-6mm on the surface. Above the upper godet hook, there is an upper godet wheel and a winding hook. The crossing hook is connected on the crossing rod, and the raw silk winding drum is arranged at the raw silk outlet of the crossing hook. The upper and lower guide wire hooks have an open induction structure, the yarn can be easily put in, and the operation is convenient to form wet raw silk and keep in contact with the guide wire roller. The interlacing hook is fixed on the interlacing rod, and the interlacing rod reciprocates left and right during silk reeling, thereby forming an online silk sheet. The godet roller adopts a hollow pipe structure, which can be fed with hot air to heat the godet roller. At the same time, a large amount of hot air is blown out from the small hole. When the raw silk sliver is in contact with the godet roller, it can dry and reduce the moisture content of the raw silk. The role of raw silk winding and forming has positive significance.

As a preference, the godet roller with a hollow structure can use a vacuum suction device to suck away the moisture on the surface of the raw silk produced when it is closely attached to the surface of the godet roller and moves back and forth, which can also reduce the moisture content of the raw silk. .

The wet raw silk and the godet roller move relative to each other. When the godet roller moves left and right, the wet raw silk between the upper guide hook 4 and the lower guide hook 3 twists and squeezes the yarn. At this time, several cocoon silk sericins that make up the raw silk are rubbed around the raw silk, so that the wet raw silk gathers tightly, thereby removing a large amount of water contained in the silk strips and the cocoon silk knots on the surface of the silk strips. The feature is that the BC segment and the AC segment rotate in the opposite direction. When the wet raw silk reaches the C position of the godet roller from the A position of the lower guide hook, it is fixed on it due to the left and right movement of the godet roller or the drive of the support rod 14. The lower guide wire hook and the upper guide wire hook reciprocate left and right, so that the AC section of the thread is twisted, and the cocoon thread is squeezed under the action of winding tension and torsional tension to form a tight raw silk, and the thread passes through the guide roller. Reverse twist occurs after C, so that the yarn eliminates the twist produced in the known AC section, and becomes a yarn without twisting characteristics, but the tight raw silk formed after passing through the AC section is due to the effect of cocoon silk sericin. It will not be dispersed due to canceling the twist, so the raw silk produced by the technology of the invention not only has a smooth surface, but also gathers cocoons well.

The netting hook 7 is fixed on the netting bar 8, and the netting bar reciprocates left and right when the silk is reeled, thereby forming a silk sheet on the net.

A special device for gathering raw silk in a wet state in this example, as shown in Figures 1 and 2, includes a plurality of connecting wings 1 through which cocoon threads 15 can pass through, and a thread collecting device 2 and a lower guide wire hook are successively arranged above the connecting wings 3. The upper guide wire hook 4, the lower guide wire hook and the upper guide wire hook are fixed on the support 13, and the support is fixed on the support rod 14. There is a godet roller 5 between the upper and lower godet hooks. The godet roller adopts a hollow pipe structure that can pass hot air. There are several small holes with a diameter of 3-6mm on the surface. The godet roller is connected with a vacuum suction device. . The outer surface of the godet roller is covered with a layer of wear-resistant and non-slip rubber.
