Description

Technical Field

[0001] This invention relates to the field of wool spinning machinery technology, and in particular to a high-efficiency wool spinning machine. Background Technology

[0002] The wool mixing machine is one of the most commonly used pieces of equipment in textile machinery. It is mainly used for wool mixing, blending, and opening before combing in the wool spinning process. The wool mixing machine uses the impact and tearing action of the protruding barbs to further break the clumps of wool into smaller pieces to achieve the opening requirements, and mixes the wool at the same time.

[0003] Existing wool-mixing machines suffer from bearing problems due to lint trapping over time, severely impacting equipment operation. When power is off, the cylinder roller continues to rotate due to inertia for a period while the doffer roller stops working, causing a "blockage" in the doffer roller section. This lint accumulation reduces opening efficiency. Furthermore, the burrs used in existing wool-mixing machines are mostly straight, making it difficult for them to penetrate the raw material, resulting in poor opening effect and efficiency. To address these technical problems, this invention designs a high-efficiency wool-mixing machine. Summary of the Invention

[0014] Invention Effects

[0015] Compared with the prior art, the advantages of this invention are as follows: Firstly, the wool-making machine gathers the wool during the wool-forming and conveying stages, and sets up a baffle structure to block impurities during the opening stage, effectively reducing the equipment maintenance rate.

[0030] Please see Figures 1 to 9 The present invention provides a technical solution: a high-efficiency wool forming machine, comprising a wool coaguler 1, a conveying device 2, an opening device 3, a doffer roller 4, a first motor 51, a second motor, and a frame 6;

[0031] The conveying device 2, the loosening device 3, and the doffer roller 4 are arranged sequentially on the frame 6. The coagulator 1 and the conveying device 2 are fixedly connected. The conveying device 2 is fixedly connected to the conveyor belt 21. The pressing roller 20 is fixedly connected inside the conveying device 2. The doffer roller 4 is fixedly connected to the discharge port.

[0032] The opening device 3 includes a cylinder roller 30, a working roller 31, a stripping roller 32, a first feeding roller 33, a second feeding roller 34, a support foot 35, a retaining sleeve 36, and a bearing 37. The working roller 31, the stripping roller 32, the first feeding roller 33, and the second feeding roller 34 are rotatably connected to the cylinder roller 30. The working roller 31 and the stripping roller 32 rotate in the same direction. The first feeding roller 33 is fixed to the frame 6. Both the first feeding roller 33 and the second feeding roller 34 are equipped with gears that mesh. One end of the support foot 35 is hinged to the side plate of the cylinder roller 30, and the other end of the support foot 35 is rotatably connected to the working roller 31. The support foot 35 is rotatably connected to the bearing 37. Grooves are respectively opened on the support foot 35 and the connecting flange 313, and both ends of the retaining sleeve 36 are respectively inserted into the grooves.

[0033] The hair-forming device 1 includes a housing 10, a geared motor frame 11, a turntable 12, a geared motor 13, a feed inlet 14, an air intake 15, a supplementary air intake 16, a roller 17, blades 171, a baffle 18, and a baffle sealing gasket 181. The geared motor frame 11 is fixedly connected to the housing 10, the geared motor 13 is fixedly connected to the geared motor frame 11, the output end of the geared motor 13 is fixedly connected to the turntable 12, the turntable 12 and the housing 10 are rotatably connected, and the feed inlet 14 is fixedly connected to the housing 10. The air intake 15 is located on the outer shell 10, and the outer shell 10 is provided with an air supply 16. The roller 17 and the turntable 12 are fixedly connected, and the outer shell 10 and the roller 17 are rotatably connected. Multiple blades 171 are fixedly attached to the outer side of the roller 17. The outer edge of the blades 171 is made of rubber. The blades 171 are tightly pressed against the inner edge of the outer shell 10. The baffle 18 is fixedly attached below the air intake 15 and is rotatably connected to the roller 17. The baffle sealing gasket 181 is fixedly attached to both ends of the baffle 18.

[0034] The working roller 31 includes a toothed section, a working roller cylinder 312, a connecting flange 313, a supporting flange 314, a gasket 315, an anti-loosening gasket 316, a nut 317, and a rotating shaft 311. The working roller cylinder 312 has a square hole, the toothed section is inserted into the square hole, the stop step is tightly against the surface of the working roller cylinder 312, the gasket 315, the anti-loosening gasket 316, and the nut 317 are sequentially fitted onto the toothed section, the nut 317 is threadedly connected to the toothed section, both ends of the working roller cylinder 312 are respectively screwed to the connecting flange 313, the supporting flange 314 is screwed to the working roller cylinder 312, and the connecting flange 313 and the supporting flange 314 are fitted onto the rotating shaft 311.

[0035] The wolf tooth includes a hook-shaped portion 301, a stop portion 302, an insert portion 303, and a cylindrical portion 304 arranged from top to bottom; the width of the hook-shaped portion 301 increases from top to bottom, the hook-shaped portion 301 and the stop portion 302 are smoothly transitioned, the cross-section of the insert portion 303 is square, a stop step is formed between the stop portion 302 and the insert portion 303, and the cylindrical portion 304 is provided with external threads.

[0036] The first motor 51 is connected to the first feed roller 33 via a pulley, and the second motor is connected to the cylinder roller 30 and the doffer roller 4 via two pulleys respectively.

[0037] When in use, the raw material to be processed enters the coagulating machine 1 through the feed port 14. The reduction motor 13 works and drives the turntable 12 to rotate. The turntable 12 drives the roller 17 to rotate. The baffle 18 pushes the raw material clockwise. As the air intake 15 continuously draws in air, the raw material is adsorbed on the surface of the roller 17.

[0038] like Figure 3As shown, blade 171 rotates clockwise. The baffle sealing gasket 181 and blade 171 on the baffle 18 are made of rubber. When blade 171 rotates to the position shown in the figure, blade 171 and baffle 18 divide the working area into upper and lower areas. At this time, the air intake 15 in the upper area continuously draws air, while the lower area is not affected by air intake due to good sealing and forms negative pressure.

[0039] Air is supplied to the lower half of the area through the air inlet 16, causing the raw materials to fall under their own weight.

[0040] The raw material falls into the conveyor device 2 below. The conveyor belt 21 in the conveyor device 2 works to transport the raw material to the opening device 3. The raw material is scattered in the chamber of the conveyor device 2, and some of the raw material floats on the top. The pressing roller 20 is set to rotate and press the raw material scattered on the top onto the conveyor belt 21.

[0041] The raw material is conveyed by the conveyor belt 21 to the first feeding roller 33. The first feeding roller 33 rotates counterclockwise, and the second feeding roller 34, which meshes with the first feeding roller 33, rotates clockwise, conveying the raw material between the cylinder roller 30 and the feeding roller. As the cylinder roller 30 continues to rotate counterclockwise, the raw material is conveyed along the circumferential direction of the cylinder roller 30.

[0042] Next to the second feeding roller 34 and each work roller 31, there is a stripping roller 32. A small amount of wool may stick to the work roller 31 and the second feeding roller 34. During the opening process, the stripping roller 32 rotates in the same direction as the work roller 31, stripping the wool off the work roller 31. The rotation speed of the stripping roller 32 is less than the rotation speed of the second feeding roller 34 and the work roller 31.

[0043] The raw material is loosened by the rotation of the cylinder roller 30 and the working roller 31 and transported to the doffer roller 4. The raw material is then conveyed to the discharge port by the doffer roller 4.

[0044] When the existing wool mixing machine is powered off, the cylinder roller will continue to rotate for a while due to inertia, which can cause a "blockage" in the doffer roller 4 stage. Most of the wool will accumulate on the doffer roller 4, which may damage the machine.

[0045] In this high-efficiency wool feeding machine, the first motor 51 is connected to the first feeding roller 33 via a pulley, and the second motor is connected to the cylinder roller 30 and the doffer roller 4 via two pulleys. When the power is off, the cylinder roller 30 and the doffer roller 4 controlled by the second motor stop working, while the first motor 51 controls the first feeding roller 33 independently. The power supply to the first motor 51 can be manually cut off to stop the continuous feeding of wool.

[0046] The serrated mechanism on the working roller 31 can sequentially pierce the material along the rotation direction of the working roller 312, resulting in higher opening efficiency compared to traditional straight serrated burrs.

[0047] The working roller 312 is composed of multiple arc-shaped plates spliced ​​together tip to tip. If the adjacent arc-shaped plates are spliced ​​together in a face-to-face manner, the face-to-face joints often result in burrs due to processing accuracy issues. To avoid burrs, the processing accuracy needs to be greatly improved, which will increase costs.

[0048] Grooves are respectively provided on the support foot 35 and the connecting flange 313, and the two ends of the retainer 36 are respectively inserted into the grooves. When the working roller 31 is working, the retainer 36 can effectively prevent the material from entering the rotating shaft 311 or the bearing 37, thus preventing equipment problems caused by the material getting caught.

[0049] Preferably, the doffer roller 4 is also fitted with this type of retainer 36 to prevent the doffer roller 4 from getting caught in fibers.

[0050] The working roller 31 has smooth ends without serrations, which allows the wool to be loosened in the middle part of the working roller 31, reducing the risk of wool getting caught.

[0051] Preferably, the arc-shaped plate joint of the working roller 312 is a pointed joint. This structure can greatly reduce the processing accuracy and processing cost, while effectively solving the problem of burrs between the arc-shaped plates.

[0052] The frame 6 is equipped with a maintenance door 61, which allows for easy access to handle debris and replace parts during maintenance.

[0053] The present invention has been described above by way of example, but the present invention is not limited to the specific embodiments described above. Any modifications or variations made based on the present invention shall fall within the scope of protection claimed by the present invention.
