Description

Technical Field

[0001] This utility model relates to the field of textile processing technology, and in particular to a spinning cohesion device. Background Technology

[0002] Ring spinning machines are equipped with multiple suction nozzles facing the yarn to remove fuzz generated during the spinning process. These nozzles are independently designed for easy disassembly and maintenance, simplifying maintenance and replacement and reducing downtime costs.

[0003] However, when converting ring spinning to compact spinning, a negative pressure tube must be installed on the roller seat. The yarn is gathered through the negative pressure tube and then sucked up by the suction nozzle to remove fuzz. Changes in the position where the yarn fuzz is removed necessitate adjusting the position of the suction nozzle accordingly. Since multiple suction nozzles are installed separately, each requires individual adjustment, making assembly and debugging difficult.

[0004] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art. Utility Model Content

[0005] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a spinning cohesion device that facilitates the switching between ring spinning and compact spinning.

[0006] The technical solution of this utility model is as follows: The spinning and cohesive device includes a roller seat, a negative pressure tube and a cotton suction tube disposed on the roller seat; the negative pressure tube and the cotton suction tube are respectively connected to a negative pressure source; the cotton suction tube is disposed parallel to the negative pressure tube; along the length direction of the negative pressure tube, the cotton suction tube has at least two cotton suction ports facing the negative pressure tube; a connecting tube is disposed on the cotton suction tube; the connecting tube is connected to the negative pressure source.

[0007] A further technical solution is that, along the axial plane of the cotton-suction tube, the cross-section of the internal cavity of the cotton-suction tube is increased on the side away from the cotton-suction opening.

[0008] A further technical solution is that the suction port is a flat opening, and the long side of the suction port is parallel to the axis of the negative pressure tube.

[0009] A further technical solution is that, on the side away from the cotton-absorbing tube, the diameter of the connecting tube first increases and then decreases, forming an expanding section and a contracting section.

[0010] A further technical solution is that the connecting pipe is connected to the negative pressure source through a pipeline, and the pipeline is made of rubber.

[0011] A further technical solution is that eight cotton suction ports are opened on the cotton suction tube.

[0012] A further technical solution is that plugs are sealed at both ends of the cotton suction tube; an overlapping portion extends from the plug; and a third slot is provided on the roller seat for the overlapping portion to be inserted.

[0013] A further technical solution is that a traction assembly is also provided on the roller seat; the traction assembly includes a front roller, a middle roller, and a rear roller.

[0014] A further technical solution is that a first slot and a second slot are provided on the roller seat, the front roller is inserted into the first slot, and the negative pressure tube is inserted into the second slot.

[0015] A further technical solution is that a negative pressure hole is opened on the negative pressure pipe and a mesh ring is fitted on it; the mesh ring covers the negative pressure hole.

[0016] The beneficial technical effects of this utility model are as follows: (1) The spinning cohesion device of this utility model is provided with a negative pressure tube and a cotton suction tube on the roller seat. During spinning, the yarn is gathered by the negative pressure tube and the cotton suction tube removes the fuzz, improving the quality of the yarn. Moreover, multiple cotton suction ports are opened on the cotton suction tube, and the fuzz of multiple yarn positions can be removed at the same time through one cotton suction tube. By adjusting the angle position of the cotton suction tube to correspond to the position of one cotton suction port and the yarn, all cotton suction ports can be adjusted to the corresponding positions simultaneously, improving the adjustment efficiency of the cotton suction port positions. When the spinning machine switches between ring spinning and compact spinning, it is only necessary to adjust the interface of the cotton suction tube to complete the position adjustment of all cotton suction ports, reducing the downtime cost of the spinning machine when switching spinning modes. In addition, all cotton suction ports can be connected to the negative pressure source through a connecting pipe, simplifying the structure of the spinning machine.

[0017] (2) Furthermore, the closer to the suction port, the smaller the cross-section of the internal cavity of the suction tube. Correspondingly, the airflow velocity will also increase near the suction port. When removing lint, the increased airflow velocity significantly enhances the negative pressure at the suction port, thereby improving the lint removal efficiency.

[0018] (3) Furthermore, an expansion section is provided on the connecting pipe. The cross-section of the expansion section gradually decreases on the side near the suction tube, which increases the gas flow rate and local negative pressure, and efficiently removes the fuzz from the suction tube. In addition, when a straight-cylinder tube absorbs airflow, it is easy to form vortices at the inlet, which affects the intake of fuzz. The variable diameter structure of the reduction section can reduce the generation of transverse vortices and improve the fuzz absorption efficiency. Attached Figure Description

[0026] Figure 1 A three-dimensional structural schematic diagram of a spinning cohesion apparatus according to an embodiment of the present disclosure is shown. Figure 2 A partially enlarged view of the spinning cohesion apparatus according to an embodiment of the present disclosure is shown at point A. Figure 3 A schematic diagram of the assembly structure of the suction tube and the pipe in a spinning cohesion apparatus according to an embodiment of this disclosure is shown. Please refer to... Figure 1 , Figure 2 and Figure 3The spinning and gathering device includes a roller seat 1, a negative pressure tube 3 and a suction tube 4 mounted on the roller seat 1. A traction assembly is mounted on the roller seat 1. The traction assembly includes a front roller 51, a middle roller 52, and a rear roller 53. The front roller 51, middle roller 52, and rear roller 53 work in succession to stretch and guide the yarn into the working area of ​​the negative pressure tube 3. Negative pressure tube 3 and suction tube 4 are respectively connected to a negative pressure source. Negative pressure holes 31 are formed on the negative pressure tube 3, and a mesh ring 32 is fitted onto them. The mesh ring 32 covers the negative pressure holes 31. The negative pressure source can be a fan. The suction tube 4 is positioned parallel to the negative pressure tube 3. During spinning, the yarn is gathered by the negative pressure tube 3 and its fuzz is removed by the suction tube 4, improving the quality of the yarn. Along the length of the negative pressure tube 3, the suction tube 4 has at least two suction ports 42 facing the negative pressure tube 3. A single suction tube 4 can simultaneously remove fuzz from multiple yarn positions. By adjusting the angle of the suction tube 4 to correspond to the position of one suction port 42 and the yarn, all suction ports 42 can be adjusted to their corresponding positions simultaneously, improving the adjustment efficiency of the suction port 42 positions. When switching between ring spinning and compact spinning modes, only the interface of the suction tube 4 needs to be adjusted to complete the position adjustment of all suction ports 42, reducing the downtime cost of the spinning machine when switching spinning modes. A connecting pipe 43 is provided on the suction tube 4. The connecting pipe 43 is connected to a negative pressure source. All suction ports 42 can be connected to the negative pressure source through a single connecting pipe 43, simplifying the structure of the spinning machine.

[0027] Preferably, the roller seat 1 has a first slot 11 and a second slot, with the front roller 51 inserted into the first slot 11 and the negative pressure pipe 3 inserted into the second slot. A bearing (not shown in the figure) can be installed in the first slot 11 to rotate the front roller 51. A bearing seat (not shown in the figure) can also be installed on the roller seat 1, with a bearing mounted on the bearing seat to rotate either the middle roller 52 or the rear roller 53. The bearing seat and the roller seat 1 can be connected by bolts.

[0028] More preferably, plugs 41 are respectively provided at both ends of the suction tube 4, and the plugs 41 and the suction tube 4 can be interference-fitted to seal the ends of the suction tube 4. An overlapping portion 411 extends from the plug 41. A third groove is provided on the roller seat 1 for the overlapping portion 411 to be inserted, and the overlapping portion 411 is interference-fitted with the third groove. After the third groove and the overlapping portion 411 are engaged, the suction port 42 faces the negative pressure tube 3.

[0029] Figure 4 The diagram shown is a right-side view of the suction tube in a spinning and cohesive apparatus according to an embodiment of this disclosure. Please refer to... Figure 3 and Figure 4Along the axial plane of the suction tube 4, the cross-section of the internal cavity of the suction tube 4 increases towards the side away from the suction port 42. That is, the closer to the suction port 42, the smaller the cross-section of the internal cavity of the suction tube 4. Correspondingly, the airflow velocity also increases near the suction port 42. When removing lint, the increased airflow velocity significantly enhances the negative pressure at the suction port 42, improving the lint removal efficiency.

[0030] Preferably, the suction port 42 is a flat opening, with its long side parallel to the axis of the negative pressure tube 3. This extends the lateral coverage of the suction port 42, allowing for more comprehensive removal of lint from both sides of the yarn.

[0031] More preferably, eight suction ports 42 can be provided on the suction tube 4. Due to factors such as friction of the pipe 2 and airflow diffusion, the suction force of the suction ports 42 will decrease on the side away from the connecting pipe 43. Therefore, providing eight suction ports 42 avoids that having too many suction ports 42 will affect the suction effect of the suction tube 4 in removing lint. In addition, if the suction tube 4 is too long and the structure is too complicated, it will also be inconvenient for maintenance and cleaning.

[0032] Please refer to Figure 3 and Figure 4 Towards the side furthest from the suction tube 4, the diameter of the connecting pipe 43 first increases and then decreases, forming an expanding section 431 and a contracting section 432. The expanding section 431, with its cross-section gradually decreasing on the side closest to the suction tube 4, increases the gas flow rate and local negative pressure, efficiently removing lint from the suction tube 4. Furthermore, a straight-shaped tube body tends to form vortices at the inlet when absorbing airflow, affecting lint absorption. The variable diameter structure of the contracting section 432 reduces the generation of transverse vortices, improving lint absorption efficiency. The gradually decreasing cross-sectional area on the side of the contracting section 432 furthest from the suction tube 4 facilitates the fitting of the pipe 2 onto the connecting pipe 43. Preferably, the connecting pipe 43 is connected to the negative pressure source through the pipe 2, which is made of rubber. The rubber pipe 2 can be bent at a certain angle to ensure a stable connection between the pipe 2 and the connecting pipe 43 after the suction tube 4 is adjusted.

[0033] The specific workflow of this utility model is as follows: During spinning, the yarn passes through the spinning condenser via the back roller 53, middle roller 52, front roller 51, negative pressure tube 3, and suction tube 4. A fan connected to the negative pressure tube 3 starts, drawing airflow to create negative pressure and gather the yarn within the tube. A fan connected to the suction tube 4 starts, drawing airflow along the suction inlet 42, suction tube 4, connecting pipe 43, and pipe 2, creating negative pressure within the suction tube 4. Multiple suction inlets 42 on the suction tube 4 simultaneously remove fuzz from corresponding locations.

[0034] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0035] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
