Description

Technical Field

[0001] The present application relates to the field of knitting equipment, and in particular to a double-sided high-speed weft knitting circular machine. Background Art

[0002] Double-sided high-speed weft knitting circular machine is widely used in textile, clothing, shoes and hats, luggage and other industries. It is an important equipment for producing high-quality double-sided knitted fabrics.

[0003] In the related technology, a Chinese patent with authorization announcement number CN114000259B discloses an automatic dust-removing double-sided knitting circular machine, which is provided with a fan for blowing out the flying catkins on the yarn on the outer wall of the machine body, and a disc arranged around the outer circumference of the machine body and a plurality of shielding components for collecting the flying catkins; a brush for cleaning the shielding component is installed inside the cavity of the shielding component, and the shielding component is a filter plate. During the operation of the circular machine, the fan inside the machine body blows dust, flying catkins and other impurities on the yarn to the shielding component, so that the impurities enter the interior of the shielding component, and then the brush is driven by the driving device to clean the impurities in the cavity of the shielding component to improve the dust removal efficiency.

[0004] Regarding the above-mentioned related technologies, there are the following defects: when using a filter plate as a shielding component to collect impurities, a brush is required to continuously clean the filter plate to maintain the adsorption capacity of the filter plate, and the brush realizes the cleaning function by rotating around a disc.

[0026] The following is combined with Figure 1-2 This application is described in further detail.

[0027] The present application embodiment discloses a double-sided high-speed weft knitting circular machine, referring to Figure 1 and Figure 2 , including a body 1, a spray mechanism 5, and a blower mechanism 2 installed in the body interior 11. The blower mechanism 2 includes a plurality of fans, which are installed on the circumference of the body interior 11 in a circumferentially distributed manner through a support frame, and blow flying catkins on the yarn in the body interior 11 to the outside.

[0028] A support plate 4 is fixedly mounted on the outer wall of the machine body 1. The support plate 4 is annular and surrounds the outer peripheral surface of the machine body 1. An annular baffle 3 is fixed on the support plate 4, wherein the axis of the annular baffle 3 coincides with the axis of the support plate 4. The annular baffle 3 is arranged around the outside of the air blowing mechanism 2. The spray mechanism 5 is used to spray water on the inner wall of the annular baffle 3 to form a water curtain. The air blowing mechanism 2 blows the yarn flying catkins to the inner wall of the annular baffle 3. The spray mechanism 5 cooperates with the annular baffle 3 so that the interior 11 of the machine body is surrounded by the annular water curtain, and under the action of the air blowing mechanism 2, the yarn flying catkins floating in the interior 11 of the machine body are blown to the annular water curtain, so that the flying catkins and other debris are melted in the water flow. The flowing water curtain can continuously capture impurities, which is conducive to improving the impurity collection efficiency. The inner side of the annular baffle 3, the surface of the support plate 4 and the cylindrical wall of the interior 11 of the machine body constitute an annular water trough to collect water flowing down from the inner wall of the annular baffle 3. The support plate 4 is provided with a plurality of circumferentially distributed drainage holes 41 along its thickness direction. The plurality of drainage holes 41 are close to the inner side of the annular baffle 3 . Water flowing down from the inner side of the annular baffle 3 can be discharged to the outside of the annular baffle 3 through the drainage holes 41 .

[0029] In this embodiment, the spray mechanism 5 includes a water storage tank 51 disposed below the support plate 4 and a spray assembly 52 connected to the water storage tank 51. The water storage tank 51 is annular and the top is connected to a plurality of drainage holes 41. The water flowing down from the inner side of the annular baffle 3 can be discharged into the water storage tank 51 through the drainage holes 41, thereby recycling the water so that the water storage tank 51 can continuously supply water to the spray assembly 52. ​​In addition, an annular support plate 12 is fixed to the outer wall of the body 1, and the annular support plate 12 is arranged around the outer wall of the body 1 and supports the bottom of the water storage tank 51. This is conducive to improving the stability of the water storage tank 51 and improving the deformation of the bottom of the water storage tank 51.

[0030] In this embodiment, the spray assembly 52 is installed on the top of the annular baffle 3. Specifically, the spray assembly 52 includes a water pump 521 connected to the water storage tank 51, a connecting pipe 522 connected to the output end of the water pump 521, an annular pipe 523 connected to the connecting pipe 522, and a plurality of nozzles 524 connected to the annular pipe 523. The annular pipe 523 is installed around the inner side of the top of the annular baffle 3. The plurality of nozzles 524 are spaced and distributed along the surrounding direction of the annular pipe 523 and are arranged downwardly and tilted toward the inner wall of the annular baffle 3. Under the action of the water pump 521, the water in the water storage tank 51 is pumped to the connecting pipe 522 and the annular pipe 523, and finally sprayed out through a plurality of nozzles 524, so that the spray area of ​​the spray assembly 52 surrounds the inner side of the annular baffle 3. In addition, since there is an angle between the nozzle 524 and the annular baffle 3, the situation of vertical impact on the annular baffle 3 is avoided, which is conducive to improving the problem of water mist drifting and affecting the normal weaving work of the equipment.

[0031] In this embodiment, a shielding plate 31 is fixedly mounted on the top of the annular baffle 3. The shielding plate 31 is annular and bent toward the inner side of the annular baffle 3. A shielding groove 32 with an opening facing downward is formed between the shielding plate 31 and the annular baffle 3, and the annular tube 523 and a plurality of nozzles 524 are all accommodated in the shielding groove 32. Thus, the splashing water mist can be physically blocked, further improving the problem of water mist drifting and affecting the normal weaving work of the equipment. The water flow finally flows down the notch of the shielding groove 32, which is conducive to improving the flow stability of the water curtain.

[0032] In this embodiment, a filter assembly 6 is installed in the water storage tank 51, and the filter assembly 6 is located below the drain hole 41. The water flow with impurities passes through the drain hole 41 and then falls to the filter assembly 6. The filter assembly 6 filters the return water to filter out the impurities in the water flow, which is beneficial to reduce the probability of impurities blocking the spray assembly 52. ​​Specifically, the outer wall of the water storage tank 51 is provided with a plurality of circumferentially distributed sliding grooves 522, and the filter assembly 6 includes a plurality of arc-shaped filter plates 61, and the plurality of arc-shaped filter plates 61 correspond to the plurality of sliding grooves 522 one by one. The arc-shaped filter plates 61 are horizontally inserted into the water storage tank 51 through the corresponding sliding grooves 522. The plurality of arc-shaped filter plates 61 cooperate with the corresponding sliding grooves 522, which can facilitate the taking and placing of the arc-shaped filter plates 61. At the same time, the arc-shaped filter plates 61 can be replaced and cleaned one by one while the equipment is working, so that the filter assembly 6 can be cleaned without stopping the machine. It should be noted that the connecting pipe 522 of the spray assembly 52 needs to be made of a hose material to facilitate the extraction of the arc-shaped filter plate 61 adjacent to the connecting pipe 522 .

[0033] The implementation principle of a double-sided high-speed weft knitting circular knitting machine in the embodiment of the present application is: This application adopts a high-precision 36G double-sided high-speed weft knitting circular machine with a back-off height of 11mm and a back-off point scale of 102, which can ensure that the air level performance, fabric texture clarity, fabric specification stability and feel of the produced clothing fabric can achieve good results.

[0034] In terms of dust removal, when the machine body 1 is working, by starting the blowing mechanism 2 and the spraying mechanism 5 at the same time, the water pump 521 of the spraying mechanism 5 sends the water in the water tank 51 to the connecting pipe 522 and the annular pipe 523, and finally sprays it out through multiple nozzles 524. The nozzles 524 spray water on the top position of the inner wall of the annular baffle 3, and the water flows down along the inner wall of the annular baffle 3. At the same time, an annular water curtain is formed around the interior 11 of the machine body. The blowing mechanism 2 blows the yarn flying catkins to the water curtain on the inner wall of the annular baffle 3, and the flying catkins and other debris are melted in the water flow. The flowing water curtain can continuously capture impurities, which is beneficial to improving the impurity collection efficiency.

[0035] The water flowing down from the inner wall of the annular baffle 3 is collected in the annular water trough formed by the inner side of the annular baffle 3, the surface of the support plate 4 and the cylindrical wall of the body 11, and is discharged into the water storage tank 51 through the drainage hole 41, so that the water is recycled. The water storage tank 51 continuously supplies water to the spray assembly 52 to realize the water circulation function, thereby achieving the purpose of reducing energy consumption.

[0036] The water flow with impurities passes through the drainage hole 41 and falls to the arc filter plate 61 of the filter assembly 6, thereby filtering the return water to filter out the impurities in the water flow, which is beneficial to reduce the probability of impurities clogging the spray assembly 52. ​​When the equipment is in continuous operation, the arc filter plates 61 are regularly replaced and cleaned piece by piece to complete the cleaning work of the filter assembly 6 without stopping the machine.

[0037] 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.
