Description

Technical Field

[0001] The present application relates to the technical field of fabric production technology, and in particular to the production technology of high-density knitted fabrics. Background Art

[0002] Knitted fabric is a kind of grey fabric formed by knitting yarns on a knitting machine. Among them, the higher the knitting density of the fabric, the higher the durability and stability. In order to prepare high-density knitted fabrics, operators often size the yarns to form a layer of anti-fission film on the surface of the yarns to increase the tensile strength of the yarns, so that multiple yarns are easier to connect stably and less likely to break during the assembly process, thereby obtaining high-density knitted fabrics.

[0003] Most existing sizing devices include a traction mechanism, a slurry storage box, and multiple groups of yarn guide rollers. The traction mechanism is arranged on one side of the slurry storage box, and multiple groups of yarn guide rollers are arranged in the side wall of the slurry storage box at intervals, and the adjacent yarn guide rollers are at different levels. The inner cavity of the slurry storage box is loaded with slurry for coating the surface of the yarn. The traction mechanism guides the yarn to enter and pass through the inner cavity of the slurry storage box. During this process, the yarn contacts all the yarn guide rollers in turn, and then is fully stained with slurry to ensure that the yarn can be coated with slurry at all places on the surface after passing through the slurry.

[0004] However, when the yarn passes through the slurry, there is a phenomenon that the exposed wool on the surface of the yarn falls off and accumulates inside the slurry. Over time, the slurry is very likely to become locally adhered and clumped due to the mixing of a large amount of wool, which greatly affects the fluidity of the slurry and the wrapping properties of the subsequent yarn, so it needs to be improved. Summary of the invention

[0047] Reference Figure 2 The yarn guide mechanism 12 includes a yarn guide shaft 121, and one end of the yarn guide shaft 121 close to the operating table 11 is rotatably arranged on the top wall of the operating table 11. When the yarn abuts against the side wall of the yarn guide shaft 121 and passes through, the yarn guide shaft 121 can rotate with the displacement of the yarn.

[0048] Reference Figure 2In this embodiment, two sets of yarn skimming mechanisms 13 are respectively located at two radial ends of the yarn guide shaft 121, wherein each set of yarn skimming mechanism 13 includes a driving member 131, a yarn skimming brush 132 and a positioning frame 133.

The yarn passes through between the yarn guide shaft 121 and the yarn-skimming brush 132. During this process, the yarn migrates through the traction mechanism to abut against the side wall of the yarn guide shaft 121. The yarn-skimming brush 132 rotates through the output end of the driving member 131 to clean the impurities and exposed wool on the yarn, so that the impurities and broken exposed wool are separated from the yarn.

The airflow in the inner cavity of the suction guide tube 22 can pass through the attached yarn mesh plate 243, and the impurities and exposed wool sucked by the suction guide tube 22 are adhered to the attached yarn mesh plate 243, thereby reducing the phenomenon that the impurities and exposed wool enter the adsorbent 21 and damage the adsorbent 21.

[0056] Reference Figure 1 and Figure 3Yarn finishing: After the yarn is skimmed, it is subjected to a roller pressing process by a roller pressing device 3. The roller pressing device 3 includes two side plates 31, a bottom roller group 32 and a top roller group 33, wherein the two side plates 31 are parallelly welded to the top wall of the operating table 11, and the yarn guide shaft 121 and all the yarn skimming brushes 132 are located between the two side plates 31.

In order to reduce the exposed wool remaining on the yarn, in this embodiment, each first roller 331 is located between two adjacent second rollers 321. The yarn passes through the gap between a first roller 331 and two second rollers 321, and a first roller 331 and two second rollers 321 perform roller treatment on the yarn at the same time, and then the exposed wool that has not fallen off in the skimming step of the yarn is further removed by applying pressure and friction to the surface of the yarn. Then, the adsorbent 21 continuously sucks air above the operating table 11 through the suction guide 22 with the expansion cover 23 to adsorb the free exposed wool and impurities in the air.

[0059] Reference Figure 1 and Figure 4 , Sizing: The yarn is passed through the slurry through the yarn introduction device 4, wherein the yarn introduction device 4 is used to guide the displacement of the yarn and to collect the woolen yarn dropped on the yarn. The yarn introduction device 4 includes a slurry box 41 and a plurality of yarn introduction mechanisms 42. The slurry box 41 is fixed to the ground by bolts, and the slurry box 41 is located on one side of the operating table 11.

In this embodiment, the top arc plate 61 and the bottom arc plate 5 are semicircular arc plates adapted to each other, and after the side walls of the top arc plate 61 and the bottom arc plate 5 facing each other abut against each other, the top arc plate 61 and the bottom arc plate 5 jointly form a cylinder, and a circulation channel 8 is formed between the top arc plate 61 and the bottom arc plate 5, and the circulation channel 8 is used for the yarn to pass through.

[0062] Reference Figure 5 and Figure 6 The plug-in block 62 is integrally formed on the side wall of the top arc plate 61 facing the bottom arc plate 5. The bottom arc plate 5 is provided with an embedded groove 51, and the inner diameter of the embedded groove 51 is matched with the outer circumference of the plug-in block 62. After the plug-in block 62 is inserted into the inner cavity of the embedded groove 51, the top arc plate 61 is quickly positioned on the bottom arc plate 5.

At this time, the operator screws the retaining nut 73 on the positioning screw 72 to position the outer plate 71 on the positioning screw 72, so that the top arc plate 61 is tightly pressed against the bottom arc plate 5.

[0064] Reference Figure 4 The top arc plate 61 is provided with a reserved channel 611, which is used to allow the slurry in the slurry box 41 to enter the inner cavity of the circulation channel 8, so that the slurry can infiltrate the yarn and coat the yarn. The slurry filter screen 63 is welded to the side wall of the reserved channel 611 to allow the slurry to flow freely between the circulation channel 8 and the slurry box 41, and to reduce the phenomenon that the large-sized exposed wool yarn falls off the yarn and enters the inner cavity of the slurry box 41 through the reserved channel 611.

[0065] Reference Figure 5 , the connecting strip 64 is welded to the side wall of the pulp filter screen plate 63 facing the circulation channel 8, the arc filter plate 65 is welded to the end of the connecting strip 64 away from the pulp filter screen plate 63, and the outer circumference of the arc filter plate 65 is greater than the outer diameter of the connecting strip 64. In this embodiment, the arc filter plate 65 can be a bowl-shaped arc plate, and the adjacent arc filter plates 65 are together under the pulp filter screen plate 63 to abut against the exposed wool yarns that fall off in the circulation channel 8, thereby helping to reduce the phenomenon that the exposed wool yarns pass through the pulp filter screen plate 63 and enter the inner cavity of the pulp box 41, ensuring the fluidity of the pulp in the inner cavity of the pulp box 41, and reducing the phenomenon that the pulp is locally adhered to and agglomerated due to the addition of external wool yarns.

[0066] Weaving: The yarn after starching is heat-dried in a heat dryer, and then the heat-dried yarn is woven by a knitting machine to be compiled into grey cloth.

[0067] The implementation principle of the production process of high-density knitted fabrics in the embodiment of the present application is as follows: in the skimming and adsorption step, the yarn passes through the gap between the skimming brush 132 and the yarn guide shaft 121, and the skimming brush 132 can skim out impurities and exposed wool on the surface of the yarn. Then, the adsorption member 21 uses the suction pipe 22 with the expansion cover 23 to absorb the impurities and exposed wool on the operating table 11, thereby reducing the phenomenon of impurities and exposed wool circulating in the air.

[0068] In the yarn straightening step, a first pressing roller 331 and two second pressing rollers 321 simultaneously apply pressure and friction to the yarn surface layer, so that the exposed wool threads that failed to fall off in the skimming step of the yarn further fall off. At the same time, the suction member 21 continues to suck the exposed wool threads that fall off the yarn.

[0069] In the sizing step, the circulation channel 8 between the top arc plate 61 and the bottom arc plate 5 is used for the yarn to pass through, and the slurry in the slurry box 41 is freely circulated in the inner cavity of the circulation channel 8 and the inner cavity of the slurry box 41 through the reserved channel 611 to ensure the slurry coating effect on the yarn. In this process, the external wool yarn that falls off the yarn is blocked in the inner cavity of the circulation channel 8 by the arc filter plate 65 and the slurry filter mesh plate 63 to reduce the phenomenon of the external wool yarn entering the inner cavity of the slurry box 41 to combine with the slurry. When a certain amount of external wool yarn accumulates in the circulation channel 8, the operator removes the top arc plate 61 by screwing the retaining nut 73 to clean the external wool yarn in the circulation channel 8.

[0070] Weaving: The yarn after starching is heat-dried in a heat dryer, and then the heat-dried yarn is woven by a knitting machine to be compiled into grey cloth.

[0071] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
