DETAILED DESCRIPTION

[0034] The present invention is further described below in conjunction with the accompanying drawings and embodiments. The embodiments of the present invention include but are not limited to the following embodiments.

[0035] Embodiment 1:

[0036] like Figure 1-7As shown, the wool-making machine for improving the quality of coarse yarn provided by the present invention includes: a laying device, a loosening device, an oil spraying device and a storage device; the laying device includes a feeding flat curtain 1, the feeding flat curtain 1 adopts a semi-open design, and a plurality of cloth mechanisms 9 are evenly arranged on the feeding flat curtain 1 along the conveying direction of the material; the cloth mechanism 9 includes a U-shaped support frame 13, the support frame 13 is fixedly installed on the top of the feeding flat curtain 1 through two connecting plates 14 at the bottom, a hopper 15 is installed on one side of the support frame 13, the hopper 15 is driven by a driving assembly installed on the support frame 13, so that the hopper 15 can move back and forth laterally, and two unloading rollers 16 are installed in the hopper 15, and a gear 17 is installed at one end of the unloading roller 16, and the two gears 17 are meshed, so that the two unloading rollers 16 can be linked, and the hopper A first motor 18 is installed on one side of 15, and the first motor 18 is connected to any one of the unloading rollers 16, thereby driving the two unloading rollers 16 to rotate in opposite directions; the opening device includes a cylinder 2 installed on one side of the feeding flat curtain 1, and a feeding roller 3, a stripping roller 4, a working roller 5 and a doffer 6 are installed around the cylinder 2 respectively. The working rollers 5 are set to four groups, which is more than the number of commonly used working rollers 5, which can improve the material opening effect, and the working rollers 5 are installed with horn-like spike teeth 27, which can further improve the material opening effect of the working rollers 5; the oil injection device includes a refueling barrel 7 installed on one side of the doffer 6, and a feed pipe 10 and a discharge pipe 11 are installed on the refueling barrel 7, and the feed pipe 10 is connected to the doffer 6; the refueling device includes a plurality of refueling pipes 12 installed on the discharge pipe 11;The storage device includes a stuffy material box 8 installed at one end of the discharge pipe 11, an exhaust pipe 30 is provided on the top of the stuffy material box 8, and an exhaust fan 31 is installed on the exhaust pipe 30. When in use, a person stands on the side of the feeding flat curtain 1 and puts the material into the hopper 15. The first motor 18 is started to drive the two unloading rollers 16 to rotate towards each other. The unloading rollers 16 transport the material downward at a certain speed, so that the material falls evenly from the bottom of the hopper 15. The driving mechanism of the support frame 13 is cooperated to drive the hopper 15 to move back and forth at a uniform speed, so that the material can be evenly distributed on the conveying trough in the feeding door curtain 1. There are multiple material feeding mechanisms 9, so a variety of different materials can be arranged. The staff only needs to stand on the side of the feeding flat curtain 1 to complete the feeding and laying operations, which greatly reduces the labor intensity of the workers, and the material laying is more uniform, and it is not easy to leak. The conveying trough in the feeding flat curtain 1 sends the laid material to the feeding roller 3, and the feeding roller 3 sends the material to the cylinder 2. The material is loosened by four groups of working rollers 5 arranged on the circumference of the cylinder 2. The loosening effect is improved by increasing the number of loosening working rollers 5 and using horn-shaped nail teeth 27. Practice has proved that this design also improves color mixing The color mixing effect is improved through this step, thereby reducing the number of times the material is mixed in the rough bin, thereby reducing the occurrence of the "wool particle" problem, which is beneficial to improving the quality of subsequent products. The material then passes through the stripping roller 4 to peel off the material on the cylinder 2, and the peeled material falls into the doffer 6, and then enters the refueling barrel 7 through the feeding pipe 10. The material makes a circular motion in the refueling barrel 7 and is mixed, and finally discharged from the discharge pipe 11 into the stuffy box 8. When the material passes through the discharge pipe 11, oil and water are sprayed on the passing material through the refueling pipe 12 to moisten the material. Compared with the space of the refueling barrel 7, the discharge pipe The pipe diameter of 11 is smaller, the accuracy of oil and water spraying can be guaranteed, the contact between oil and water and materials is more complete, and it is not easy to produce waste. At the same time, the exhaust fan 31 extracts the air in the stuffy box 8, making the box negative pressure, and then the entire equipment negative pressure. The oil and water (mist) sprayed from the oil filling pipe 12 is sucked by negative pressure, so that the oil and water are distributed in the rear section of the discharge pipe 11. Combined with the use of the new loosening device, the material is more uniform, the stability of the material transmission quality in the pipeline is also significantly improved, and the overall uniformity of oil and water application of the material is significantly improved, which is conducive to avoiding the situation of insufficient oil and water. ;

[0037] By setting up new-type laying devices, loosening devices and oil spraying devices, the labor intensity of workers can be greatly reduced, and the loosening effect of materials is also improved accordingly, which is beneficial to improving product quality. At the same time, the uniformity of oil and water application is improved, which can help avoid the situation where the material and oil and water consumption rates do not match.

[0038] Embodiment 2:

[0039] like Figure 3As shown, a material-sliding plate 19 is installed in the hopper 15 , and two material-sliding plates 19 are symmetrically installed. The material enters from the top of the hopper 15 and slides along the material-sliding plate 19 to between the two discharge rollers 16 .

[0040] By installing a material-smoothing plate 19 in the hopper 15 , the material can be conveniently guided to enter between the two material-discharging rollers 16 .

[0041] Embodiment 3:

[0042] like Figure 4 As shown, a plurality of dividing plates 26 are evenly installed on the unloading roller 16, and the dividing plates 26 on the two unloading rollers 16 are staggered. The materials are unloaded in sections through the dividing plates 26, which is beneficial to improve the uniformity of the falling of the materials, and further helps to improve the uniformity of the laying of the materials.

[0043] By evenly installing a plurality of dividing plates 26 on the unloading roller 16 , the evenness of the laying of the material can be facilitated.

[0044] Embodiment 4:

[0045] like Figure 2-3 As shown, the driving assembly includes a track 20 and a bidirectional screw rod 21 installed on the support frame 13, a second motor 24 is installed at one end of the bidirectional screw rod 21, an L-shaped mounting plate 22 is threadedly mounted on the bidirectional screw rod 21, one end of the mounting plate 22 is fixedly connected to the hopper 15, and a plug-in end 23 of the mounting plate 22 is slidably connected to the track 20. When in use, the second motor 24 is started to rotate the bidirectional screw rod 21. Since the plug-in end 23 is connected to the track 20, the mounting plate 22 can only reciprocate along the axial direction of the bidirectional screw rod 21, thereby causing the hopper 15 to reciprocate horizontally at the top of the feeding flat curtain 1.

[0046] By providing a driving assembly including a track 20 , a bidirectional screw rod 21 , a mounting plate 22 and a second motor 24 , the hopper 15 can be conveniently driven to perform lateral reciprocating movement on the top of the feeding flat curtain 1 .

[0047] Embodiment 5:

[0048] like Figure 2 As shown, two limiters 25 are installed on the support frame 13 to prevent overtravel during the lateral movement of the hopper 15. Once overtravel occurs, the mounting plate 22 touches the limiter 25, and the limiter 25 sends a signal to the controller of the second motor 24, causing the second motor 24 to reverse, thereby preventing the hopper 15 from colliding with the inner side of the feeding flat curtain 1.

[0049] By installing two limiters 25 on the support frame 13 , the travel of the hopper 15 can be conveniently limited, thereby avoiding safety accidents such as collision between the hopper 15 and the inner side of the feeding flat curtain 1 .

[0050] Embodiment 6:

[0051] like Figure 7 As shown, a plurality of fuel injectors 28 are installed in a ring shape on the inner side of the filling pipe 12, and the fuel injectors 28 are inserted into the discharge pipe 11. During operation, oil and water are pumped into the filling pipe 12 through a high-pressure pump, and the oil and water enter the fuel injectors 28 through the filling pipe 12. The fuel injectors 28 atomize the oil and water and spray them out, so that the atomized oil and water are filled into the discharge pipe 11, and the oil and water are mixed with the continuously moving material to moisten the material.

[0052] By installing a plurality of oil spray nozzles 28 in a ring shape on the filling pipe 12, atomized oil and water can be injected into the discharge pipe 11 from all sides, so that the material and the oil and water are mixed more evenly.

[0053] Embodiment 7:

[0054] like Figure 6 As shown, a hot air blower 29 is installed at one end of the refueling barrel 7. When in use, hot air is injected into the refueling barrel 7, so that the material is baked by the hot air when rotating in the refueling barrel 7, thereby increasing the fluffiness of the material, facilitating the subsequent full mixing of the material with oil and water, and thus wetting the material more evenly. At the same time, the hot air blower 29 blows air to one end of the discharge pipe 11, which can accelerate the material to pass through the discharge pipe 11 and prevent the material from clogging the discharge pipe 11. It is worth noting that the air supply of the hot air blower 29 is small and will not affect the negative pressure transportation in the feed pipe 10. It mainly has a heating function.

[0055] By installing a hot air blower 29 at one end of the refueling barrel 7, the material can be made more fluffy and the uniformity of wetting the material can be improved.

[0056] Embodiment 8:

[0057] like Figure 1 As shown, a filter screen 32 is installed in the exhaust pipe 30 to prevent materials or debris from clogging the exhaust fan 31.

[0058] By installing the filter 32 in the exhaust pipe 30, the exhaust fan 31 can be prevented from being blocked, thereby ensuring the normal operation of the equipment.

[0059] Working principle: When in use, a person stands on the side of the feeding flat curtain 1 and puts the material into the hopper 15. The first motor 18 starts to drive the two unloading rollers 16 to rotate towards each other. The unloading rollers 16 transport the material downward at a certain speed, so that the material falls evenly from the bottom of the hopper 15. The driving mechanism of the support frame 13 drives the hopper 15 to move back and forth at a uniform speed, so that the material can be evenly distributed on the conveying trough in the feeding door curtain 1. Since there are multiple cloth mechanisms 9, a variety of different materials can be arranged. The person only needs to stand on the side of the feeding flat curtain 1. The feeding and laying operations can be completed in one place, which greatly reduces the labor intensity of workers, and the material laying is more uniform, and it is not easy to leak. The conveying trough in the feeding flat curtain 1 sends the laid material to the feeding roller 3, and the feeding roller 3 sends the material to the cylinder 2. The material is loosened by four groups of working rollers 5 arranged on the circumference of the cylinder 2. The loosening effect is improved by increasing the number of loosening working rollers 5 and using horn-shaped nail teeth 27. Practice has proved that this design also improves the color mixing effect. The color mixing effect is improved through this step, thereby reducing The number of times the material is mixed with the rough bin is reduced, thereby reducing the occurrence of the "wool particle" problem, which is beneficial to improving the quality of subsequent products. The material then passes through the stripping roller 4 to peel off the material on the cylinder 2, and the peeled material falls into the doffer 6, and then enters the refueling barrel 7 through the feed pipe 10. The material makes a circular motion in the refueling barrel 7 and is mixed, and finally discharged from the discharge pipe 11 into the stuffy box 8. When the material passes through the discharge pipe 11, oil and water are sprayed on the passing material through the refueling pipe 12 to moisten the material. Compared with the space of the refueling barrel 7, the diameter of the discharge pipe 11 is smaller, and the oil The accuracy of water spraying can be guaranteed, the contact between oil and water and materials is more complete, and waste is less likely to occur. At the same time, the exhaust fan 31 draws out the air in the stuffy box 8, making the box negative pressure, and then making the entire equipment negative pressure. The oil and water sprayed from the refueling pipe 12 are sucked out by negative pressure, so that the oil and water are distributed in the rear section of the discharge pipe 11. Combined with the use of the new loosening device, the material is made more uniform, and the stability of the transmission quality of the material in the pipeline is also significantly improved. The overall uniformity of oil and water application of the material is significantly improved, which is conducive to avoiding the occurrence of insufficient oil and water.
