Description

Technical Field

[0001] This utility model relates to the field of textile machinery, and more specifically, it relates to a friction disc false twister that facilitates the removal of fly waste. Background Technology

[0002] The friction disc false twister is the core component of the false twist texturer in the chemical fiber spinning industry. Its function is to apply twist to the running filament through the friction disc assembly, and then use its false twist effect to make the original filament acquire fluffy and elastic properties.

[0003] During the false twisting process, due to the high-speed friction between the yarn and components such as the friction disc and the yarn guide, impurities such as fiber fuzz are inevitably generated. These impurities mix to form what is known as "flying hair." In existing friction disc false twisters, the outer shell is usually a one-piece or a closed structure secured by multiple screws. When flying hair accumulates inside the outer shell, especially in the gaps of the yarn channel, if it is not cleaned in time, the accumulated flying hair is easily carried back by the running yarn, causing yarn contamination, increased fuzz, and even yarn breakage, resulting in quality defects. The yarn channel is relatively narrow, and currently, it is generally cleaned by blowing air. However, the yarn channel is prone to oil stains, which can easily stick to the flying hair, resulting in poor air cleaning effect. The dead corners are also relatively narrow, resulting in insufficient cleaning of flying hair, which can easily affect the quality of subsequent yarns.

[0004] Therefore, a new solution is needed to address this problem. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a friction disc false twister that facilitates the cleaning of fly waste.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a friction disc false twister for easy cleaning of fly waste, comprising a spindle, a friction disc assembly mounted on the spindle, and a housing for accommodating the spindle and the friction disc assembly, wherein the friction disc assembly is located above the top surface of the housing, and the housing has a slit for yarn to pass through; The gap includes a vertical channel and a teardrop-shaped guide opening. The guide opening is located at one end of the channel facing away from the friction disc assembly. A flexible metal sheet and a rigid metal sheet are detachably connected inside the gap. The flexible metal sheet is bent and installed on the inner wall of the channel, and the rigid metal sheet is installed on the bottom surface of the guide opening. The flexible metal sheet and the rigid metal sheet together form a metal bushing covering the inner wall of the gap.

[0007] The present invention is further configured such that: a plurality of embedded blocks are fixedly connected to one side of the flexible metal sheet; a groove communicating with the top surface of the outer shell is provided on the inner wall of the channel; the embedded blocks are embedded in the groove from top to bottom; the flexible metal sheet includes an upper top surface flush with the top surface of the shell and a lower bottom surface that fits against the bottom surface of the guide port; the distance between the embedded block and the upper top surface is less than the minimum distance between the friction disc assembly and the top surface of the outer shell.

[0008] The present invention is further configured such that: the flexible metal sheet is provided with a bending line, and among the plurality of embedded blocks, the closer the embedded block is to the bending line, the greater the distance between the embedded block and the upper top surface.

[0009] The present invention is further configured such that the flexible metal sheet has elastic deformation capability.

[0010] The present invention is further configured such that: through holes are provided on both the rigid metal sheet and the flexible metal sheet, and mounting holes are provided on the outer wall of the housing and the bottom surface of the guide port, and a screw threaded into the mounting hole passes through the through hole.

[0011] The present invention is further configured such that: the through hole on the rigid metal sheet includes a small hole and a large hole that are interconnected, and the nut of the screw is accommodated in the large hole.

[0012] In summary, this utility model has the following beneficial effects: When the false twister is working, the yarn passes through the surface of the metal bushing. The smooth metal sheet ensures the passage of the yarn. When there is a lot of fly ash accumulating inside the metal bushing and affecting the yarn conduction, the flexible metal sheet and the rigid metal sheet are disassembled. The flexible metal sheet can undergo elastic deformation, changing from a bent state to a more horizontal state, thus eliminating dead corners and facilitating the cleaning of fly ash on the surface. In addition, the rigid metal sheet and the flexible metal sheet can be soaked and cleaned, which facilitates the removal of surface oil and ensures that fly ash residue on the shell is reduced.

[0015] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0016] A friction disc false twister for easy cleaning of fly waste, such as Figure 1 , Figure 2 and Figure 3 As shown, the device includes a spindle 1, a friction disc assembly mounted on the spindle 1, and a housing 2 that houses the spindle 1 and the friction disc assembly. The friction disc assembly is located above the top surface of the housing 2. A slit is provided on the housing 2 for the yarn to pass through. The friction disc assembly includes several friction discs arranged in a linear array along the length of the spindle 1. The slit includes a vertical channel 3 and a teardrop-shaped guide opening 4. The guide opening 4 is located at the end of the channel 3 facing away from the friction disc assembly. A flexible metal sheet 5 and a rigid metal sheet 6 are detachably connected within the slit. The flexible metal sheet 5 has elastic deformation capability. After bending, the flexible metal sheet 5 is installed and adhered to the inner wall of the channel 3. The rigid metal sheet 6 is installed on the bottom surface of the guide opening 4. The flexible metal sheet 5 and the rigid metal sheet 6 together form a metal bushing covering the inner wall of the slit. The flexible metal sheet 5 includes an upper top surface flush with the top surface of the housing and a lower bottom surface adhering to the bottom surface of the guide opening 4. Both the flexible metal sheet 5 and the rigid metal sheet 6 are installed... When mounted on the housing, the top surface of the flexible metal sheet 5 is flush with the top surface of the housing, and the bottom surface of the flexible metal sheet 5 abuts against the bottom surface of the guide port 4. The rigid metal sheet 6 is attached to the bottom surface of the guide port 4, and the outer peripheral wall of the rigid metal sheet 6 abuts against the flexible metal sheet 5, thus providing support for the lower end of the flexible metal sheet 5. When the false twister is working, the yarn passes through the surface of the metal bushing. The metal sheet has a smooth surface, which can ensure the passage of the yarn. When there is a lot of fly shavings accumulating inside the metal bushing, affecting the yarn conduction, the flexible metal sheet 5 and the rigid metal sheet 6 can be disassembled. The flexible metal sheet 5 can undergo elastic deformation, thus changing from a bent state to a more horizontal state, thereby eliminating dead corners and facilitating the cleaning of surface fly shavings. The rigid metal sheet 6 is teardrop-shaped and relatively flat. Both the rigid metal sheet 6 and the flexible metal sheet 5 can be soaked and cleaned, which facilitates the removal of surface oil and ensures that fly shavings remain on the housing.

[0017] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, a number of embedded blocks 7 are fixedly connected to one side of the flexible metal sheet 5. A groove 8 communicating with the top surface of the outer shell 2 is formed on the inner wall of the channel 3. The embedded blocks 7 are embedded in the groove 8 from top to bottom. The distance between the embedded block 7 and the upper top surface is less than the minimum distance between the friction disc assembly and the top surface of the outer shell 2. It should be explained that the minimum distance between the friction disc assembly and the top surface of the outer shell 2 is the distance between the lowest point of the friction disc closest to the shell and the top surface of the shell. This arrangement ensures that the friction disc does not interfere with the embedding process when the embedded block 7 is embedded. A bending line 9 is provided on the flexible metal sheet 5. Among the embedded blocks 7, the closer the embedded block 7 is to the bending line 9, the smaller the distance between the embedded block 7 and the upper top surface. The greater the distance between them, the better. During the installation of the flexible metal sheet 5, the flexible metal sheet 5 is first bent, and then the embedding block 7 closest to the bending line 9 is embedded into the corresponding embedding groove to determine the bending degree closest to the bending line 9. Then the bending degree of other positions of the flexible metal sheet 5 is adjusted so that the remaining embedding blocks 7 are inserted one by one. This setting can ensure that the bending degree of each position is adapted and ensure the fit between the flexible metal sheet 5 and the inner wall of the channel 3. Subsequently, the rigid metal sheet 6 is inserted into the guide port 4 along the bottom surface of the guide port 4 so that the rigid metal sheet 6 opens the lower end of the flexible metal sheet 5, thereby ensuring the fit between the lower end of the flexible metal sheet 5 and the inner wall of the channel 3.

[0018] like Figure 3 and Figure 4 As shown, both the rigid metal sheet 6 and the flexible metal sheet 5 have through holes 10, and the outer wall of the housing and the bottom surface of the guide port 4 have mounting holes 11. A screw threaded into the mounting hole 11 passes through the through hole 10. After the flexible metal sheet 5 and the rigid metal sheet 6 are placed in their corresponding positions, the flexible metal sheet 5 and the rigid metal sheet 6 are fixed with screws. The screws enable the flexible metal sheet 5 and the rigid metal sheet 6 to be detachably connected, while ensuring their stability in the installed state. The through holes 10 on the rigid metal sheet 6 include small holes and large holes that are interconnected. The screw nut is accommodated in the large hole. This arrangement ensures that the screw is not exposed on the surface of the rigid metal sheet 6, thus ensuring the smoothness of the surface of the rigid metal sheet 6. The screw on the flexible metal sheet 5 is not located in the gap. This arrangement ensures that the placement of the screw will not affect the transmission of yarn in the gap.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
