[0024] The present invention will be further described below with reference to specific embodiments and accompanying drawings.

[0025] See Figure 1-8As shown, an improved dust removal and fluff blowing device for a knitting machine is provided, which includes a support shaft 5, a casing 6 rotatably mounted on the support shaft 5, a plurality of dust removal fans 7 mounted on the outside of the casing 6 and used for dust removal, and a driving mechanism 8 for driving the casing 6 to rotate relative to the support shaft 5. A plurality of air jet pipes 9 are also provided on the outside of the casing 6, and a rotatable air jet nozzle 100 for blowing fluff is provided at the end of the air jet nozzle 100, and the air jet nozzle 100 has an air jet hole 21 with at least one outlet 212 which is not at the rotation axis. When the present invention is working, the support shaft 5 is used to hang and install the present invention, and the driving mechanism 8 drives the casing 6 to rotate relative to the support shaft 5, and the dust removal fan 7 performs a circular motion with the support shaft 5 as the center, so that the dust removal fan 7 can achieve large-area dust removal; at the same time, the air jet pipe 9 also performs a circular motion with the support shaft 5 as the center, and the high-pressure gas input by the air jet pipe 9 is ejected through the air jet hole 21 of the air nozzle 100, and the air jet nozzle 100 also rotates with the end of the air jet pipe 9 as the axis, and the air jet hole 21 does not rotate at the axis, so that the air nozzle 100 can also achieve 360-degree rotation to spray air over a large area, thereby blowing away the broken cotton wool on the fabric to clean it, and the cleaning area is large and the cleaning efficiency is high. At the same time, the air jet nozzle 100 also performs a circular motion to blow cotton wool over a large area of ​​fabric to meet production needs.

[0026] An air intake seat 51 is also fixed on the support shaft 5, and the air intake seat 51 has an L-shaped air intake hole 511, and the upper part of the casing 6 has an air cavity 61, the lower part of the air intake seat 51 extends into the casing 6 and forms a sealed contact, and the lower end of the air intake hole 511 is connected to the air cavity 61, and the upper end of the air intake hole 511 is connected to the air joint, and the outside of the casing 6 is provided with an air outlet 62 connected to the air cavity 61, and the injection pipe 9 is connected to the air outlet 62, wherein sealing rings are provided between the upper and lower ends of the air intake seat 51 and the upper and lower inner walls of the air cavity 61 to ensure the sealing of the air cavity 61, and also to ensure that when the casing 6 and the air intake seat 51 rotate relative to each other, the air cavity 61 is also a closed chamber. During air supply, the air connector and air pipe are connected to the air supply device, which supplies high-pressure gas. This high-pressure gas enters the air cavity 61 in the upper portion of the housing 6 through the air inlet hole 511, then passes through the air injection pipe 9 and is ejected from the air injection hole 21 of the air injection nozzle 100. Even if the housing 6 rotates relative to the support shaft 5, the air connector and air pipe do not rotate with the housing 6, and the air cavity 61 remains connected to the air inlet hole 511 of the air inlet seat 51, thereby ensuring the normal supply of high-pressure gas and preventing the air supply from being disconnected due to rotation.

[0027] The air outlet 62 is provided with an internal thread, and the front end of the air injection pipe 9 is provided with an external thread. The air injection pipe 9 and the air outlet 62 are fixedly connected by the external and internal threads, and the assembly structure is simple and stable.

[0028] The air injection pipe 9 includes a non-flexible connecting pipe 91 and a flexible and deformable deformable pipe 92 fixedly connected to the connecting pipe 91. The connecting pipe 91 is connected to the air outlet 62. The air injection nozzle 100 is mounted at the end of the flexible deformable pipe 92. The flexible deformable pipe 92 allows the relative position or orientation of the air injection nozzle 100 to be adjusted to meet different usage requirements.

[0029] The air nozzle 100 comprises a connector 1 having an air passage 10, and an air nozzle 2 that is sleeved on the exterior of the connector 1 and rotatable relative to the connector 1. The connector 1 is connected to the air pipe 9. A gap 20 is formed between the front end of the connector 1 and the bottom of the inner cavity of the air nozzle 2. The front end of the air nozzle 2 is provided with an air jet hole 21 that communicates with the gap 20. The inlet 211 and outlet 212 of the air jet hole 21 are not coaxial, and the outlet 212 of the air jet hole 21 is not located at the axis of rotation. As a result, the air jet hole 21 does not eject gas horizontally and directly. The air nozzle 100 has few parts, low cost, simple structure, and a reduced overall length. It occupies less space, making it more convenient to use and more conducive to meeting user requirements. When the air nozzle 100 is working, the high-pressure gas passes through the air jet pipe 9, enters along the air channel 10 of the connector 1, first enters the gap 20 formed between the front end of the connector 1 and the bottom of the inner cavity of the air jet cylinder 2, and finally is ejected through the air jet hole 21. During this process, since the air jet cylinder 2 can rotate relative to the connector 1, when the high-pressure gas passes through the gap 20 and enters the air jet hole 21 where the inlet 211 and the outlet 212 are not on the same axis, it can drive the air jet cylinder 2 to rotate relative to the connector 1, thereby enabling the air jet hole 21 of the air jet cylinder 2 to achieve 360-degree rotation to spray air over a large area, thereby more effectively cleaning the broken cotton wool on the fabric, and the cleaning area is large and the cleaning efficiency is high to meet production needs.

[0030] The jet hole 21 is an inclined straight hole, or an inclined Z-shaped hole. As an effective embodiment, the solution adopted in this embodiment is that the jet hole 21 is an inclined straight hole, and the outlet 212 of the jet hole 21 is not at the center of the front end surface of the jet cylinder 2, but at a non-center position, that is, not on the rotation axis.

[0031] The specific assembly structure of the air jet cylinder 2 and the connector 1 is as follows:

[0032] The jet tube 2 is rotatably mounted on the connector 1 via a bearing 11, wherein the connector 1 is fixedly sleeved with a bearing 11, the jet tube 2 is sleeved and fixed outside the bearing 11, and the jet tube 2 covers the outside of the connector 1, and the assembly mechanism is extremely stable.

[0033] In order to more effectively prevent the jet tube 2 from falling off, the following design is also made: the rear end of the jet tube 2 is also connected to a limiting sleeve 3, which is placed on the rear side of the bearing 11 and forms a rotatable gap with the outer surface of the connector 1. The inner diameter of the limiting sleeve 3 is smaller than the outer diameter of the bearing 11, and the limiting sleeve 3 can cooperate with the bearing 11 to limit the position of the jet tube 2, which can effectively prevent the jet tube 2 from falling off the connector 1; at the same time, the limiting sleeve 3 also plays a certain role in blocking gas, that is, a small amount of high-pressure gas is ejected in the reverse direction along the gap between the limiting sleeve 3 and the connector 1 after contacting the bottom of the inner cavity of the jet tube 2. Since a rotatable gap is formed between the limiting sleeve 3 and the outer surface of the connector 1, it can block the high-pressure gas.

[0034] Among them, the front end of the limiting sleeve 3 has a first thread section 31, and the inner side of the rear end of the jet cylinder 2 is provided with an internal thread 22. The first thread section 31 is spirally fixed to the internal thread 22, and its assembly structure is extremely stable and extremely convenient to assemble.

[0035] A sealing ring 32 is further provided between the limiting sleeve 3 and the rear end of the air jet cylinder 2 to achieve a sealing assembly effect.

[0036] In order to improve the stability of the jet tube 2 on the connector 1 and to ensure smooth rotation, the following design is made: there are at least two bearings 11, and two adjacent bearings 11 are separated by a spacer ring 4. The spacer ring 4 is fixedly sleeved on the periphery of the connector 1, and the two ends of the spacer ring 4 are respectively in contact with the inner circles of the two adjacent bearings 11, so that the bearings 11 are stably installed on the connector 1, and the jet tube 2 can be installed on the connector 1 more stably and rotate smoothly.

[0037] The outer diameter of the spacer ring 4 is smaller than the outer diameter of the bearing 11. A stepped groove 12 is provided on the periphery of the front end of the connector 1. The bearing 11 and the spacer ring 4 are both sleeved and fixed in the stepped groove 12, wherein the inner circle of the bearing 11 at the rear end contacts the vertical groove wall of the stepped groove 12. An anti-slip ring 15 is also sleeved and fixed at the front end of the stepped groove 12, and the rear end face of the anti-slip ring 15 contacts the inner circle of the front end bearing 11 to confine all bearings 11 in the stepped groove 12, thereby ensuring that all bearings 11 are stably installed on the connector 1. The anti-slip ring 15 can be fastened to the stepped groove 12 by interference fit, and the anti-slip ring 15 can be fastened to the stepped groove 12 by spiral assembly.

[0038] The rear end of the connector 1 is also provided with a hexagonal convex ring 13 and a second threaded section 14 located on the rear side of the hexagonal convex ring 13. The rear end of the connector 1 is connected to a hard air pipe. The fastening nut sleeved on the hard air pipe is spirally fixed to the second threaded section 14, and the hexagonal convex ring 13 can be limited by a tool when it needs to be disassembled later, so that the fastening nut can be better disassembled.

[0039] The upper end of the support shaft 5 is provided with a threaded connection section 52 for fixed connection with the outside world; the driving mechanism 8 includes a rotatable cloth support frame 81, a rotating disk 82 mounted in the middle of the cloth support frame 81, an L-shaped driving frame 83 fixed to the rotating disk 82, and a driving rod 84 mounted on the driving frame 83 and adjustable in height relative to the driving frame 83. The driving rod 84 abuts against the outer side of the housing 6 or the support rod 63 mounted outside the housing 6, and the dust removal fan 7 is mounted at the end of the support rod 63 in an adjustable angle. The rotating disk 82 is connected to a rotatable shaft 85, which is rotatably connected to the support shaft 5, so that when the cloth support frame 81 rotates, the support shaft 5 does not rotate with the cloth support frame 81. The cloth support frame 81 is connected to the knitting machine and is driven to rotate by the knitting machine, which is a prior art.

[0040] To sum up, when the present invention is working, the support shaft 5 is used to hang and install the present invention, and the driving mechanism 8 drives the casing 6 to rotate relative to the support shaft 5, and the dust removal fan 7 performs a circular motion with the support shaft 5 as the center, so that the dust removal fan 7 can achieve large-area dust removal; at the same time, the air jet 9 also performs a circular motion with the support shaft 5 as the center, and the high-pressure gas input by the air jet 9 is ejected through the air jet hole 21 of the air nozzle 100, and the air jet 100 also rotates with the end of the air jet pipe 9 as the axis, and the air jet hole 21 does not rotate at the axis, so that the air nozzle 100 can also achieve 360-degree rotation to spray air over a large area, and then the broken cotton wool on the fabric can be blown away to clean it. The cleaning area is large and the cleaning efficiency is high. At the same time, the air jet 100 also performs a circular motion to blow cotton wool over a large area of ​​fabric to meet production needs.
