Description

Technical Field

[0001] This utility model relates to the field of textile equipment technology, and in particular to a cotton suction tube fixing frame. Background Technology

[0002] Suction nozzles remove impurities and short fibers from the yarn during the spinning process, improving yarn quality. To accurately align multiple yarns produced simultaneously on the spinning machine, multiple suction nozzles are installed, each corresponding to a specific yarn.

[0003] The high-frequency vibrations generated during the operation of a spinning machine can cause the suction nozzles on the machine to easily shift direction due to these vibrations. This results in the nozzles not aligning with the yarn, affecting their ability to remove impurities and short fibers, and reducing yarn quality. Furthermore, when multiple suction nozzles are installed on the spinning machine, it is difficult to detect nozzle misalignment in a timely manner, further impacting yarn quality.

[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 suction tube fixing bracket to improve the stability of suction tube installation.

[0006] The technical solution of this utility model is as follows: A suction tube holder is mounted on a roller seat. The holder includes a connecting rod, a retainer sleeved on the connecting rod, and fixing blocks at both ends of the connecting rod. The retainer has a slot. The suction tube is inserted into the slot. The fixing blocks have a connecting hole. A fastener is installed in the connecting hole to connect to the roller seat. The connecting hole is oblong, with its long axis pointing towards the connecting rod.

[0007] A further technical solution involves providing a fixing hole on the fixing block. The fixing block is then fitted onto the connecting rod through the fixing hole.

[0008] A further technical solution is to open strip-shaped adjustment holes on the fixing block around the fixing hole.

[0009] A further technical solution involves providing a first fastening hole on the fixing block. The first fastening hole connects to the fixing hole.

[0010] A further technical solution is that the slot is an arc groove. Along the radial direction of the slot, the arc angle of the slot's cross-section is greater than 180°.

[0011] A further technical solution is to open a sleeve hole on the card holder, and the card holder is sleeved on the connecting rod through the sleeve hole.

[0012] A further technical solution involves creating a support groove along the axial direction of the suction tube on the card holder. The support groove connects to the sleeve hole.

[0013] A further technical solution involves installing a support block within the support groove. One end of the support block has a first arc groove that contacts the connecting rod, and the other end of the support block has a second arc groove that contacts the suction tube.

[0014] A further technical solution involves providing a limiting protrusion on the outer surface of the suction tube along its axial direction. A limiting groove is formed on the support block within the second arc groove to allow the limiting protrusion to engage.

[0015] A further technical solution involves creating an elastic groove along the radial direction of the card slot, near the end of the suction tube. One end of the elastic groove connects to the card slot, and the other end connects to the outer surface of the card slot.

[0016] The beneficial technical effects of this utility model are as follows: (1) The suction tube fixing bracket of this utility model is provided with a retainer, which engages with the suction tube. The retainer is sleeved on the connecting rod, and the connecting rod is fixed to the roller seat by a fixing block. That is, the suction tube and the roller seat are fixedly connected by the suction fixing bracket, which improves the stability of the suction tube fixation, reduces the probability of the suction tube deviation, and ensures the quality of the yarn. At the same time, the fixing hole and the roller seat are connected by a connecting hole. The connecting hole is an oblong hole, which allows for flexible adjustment of the fixing position of the suction tube along the long axis of the connecting hole to ensure that the suction tube is oriented towards the yarn. Multiple retainers can also be provided along the length of the connecting rod to fix multiple suction nozzles at the same time.

[0017] (2) Furthermore, an adjustment hole is also provided on the fixing block. The threaded connector passes through the adjustment hole and connects to the roller seat to determine the angle of the fixing block and prevent the fixing block from rotating around the fixing hole, which would cause the suction tube to deviate. The position of the threaded connector can also be adjusted along the long axis of the adjustment hole to adjust the angle of the fixing block, thereby further improving the flexibility of the suction tube fixing frame.

[0018] (3) Furthermore, the slot is an arc groove to fit the shape of the connecting rod and improve the stability of the connection between the slot and the connecting rod. At the same time, the arc angle of the radial section of the slot is >180° to ensure that the connecting rod can be engaged with the slot without slipping out of the slot.

[0024] Figure 1 A three-dimensional structural schematic diagram of a suction tube fixing bracket according to an embodiment of the present disclosure is shown. Figure 2 A partially enlarged view of the suction tube holder at point A, according to an embodiment of this disclosure, is shown. Please refer to... Figure 1 and Figure 2A suction tube 5 fixing bracket is provided on a roller seat 6. The suction tube 5 fixing bracket includes a connecting rod 2, a retainer 3 sleeved on the connecting rod 2, and fixing blocks 1 provided at both ends of the connecting rod 2. A retainer 31 is provided on the retainer 3. The suction tube 5 is inserted into the retainer 31. A connecting hole 11 is provided on the fixing block 1. A fastener (not shown in the figure) is provided in the connecting hole 11 to connect the roller seat 6. In some embodiments, the fastener can be a bolt or nut. That is, the suction tube 5 and the roller seat 6 are fixedly connected by the suction fixing bracket, which improves the stability of the suction tube 5 and reduces the probability of the suction tube 5 deviating to ensure the quality of the yarn. The connecting hole 11 is an oblong hole, and the long axis of the connecting hole 11 is set towards the connecting rod 2. At the same time, the fixing hole 12 and the roller seat 6 are connected through the connecting hole 11. The connecting hole 11 is an oblong hole, which allows the fixing position of the suction tube 5 to be flexibly adjusted along the long axis of the connecting hole 11 to ensure that the suction tube 5 is set towards the yarn. Multiple card holders 3 can also be set along the length of the connecting rod 2 to fix multiple suction nozzles at the same time.

[0025] Please refer to Figure 1 and Figure 2 The fixing block 1 has a fixing hole 12. The fixing block 1 is fitted onto the connecting rod 2 through the fixing hole 12. The fixing hole 12 and the connecting rod 2 can be an interference fit.

[0026] Preferably, a strip-shaped adjustment hole 13 is provided on the fixing block 1 around the fixing hole 12. The threaded connector passes through the adjustment hole 13 and connects to the roller seat 6 to determine the angle of the fixing block 1, preventing the fixing block 1 from rotating around the fixing hole 12 and causing the suction tube 5 to shift. The position of the threaded connector can also be adjusted along the long axis of the adjustment hole 13 to adjust the angle of the fixing block 1, further improving the flexibility of the suction tube 5 fixing bracket.

[0027] More preferably, the fixing block 1 is further provided with a first fastening hole 14. The first fastening hole 14 communicates with the fixing hole 12. In some embodiments, the first fastening hole 14 can be a threaded hole, and a screw (not shown in the figure) is screwed into the first fastening hole 14 and abuts against the connecting rod 2, thereby enhancing the connection strength between the connecting rod 2 and the fixing block 1. The screw can be replaced with various threaded fasteners known in the prior art, such as bolts.

[0028] Please refer to Figure 1 and Figure 2 The slot 31 is an arc groove. The radial direction of the slot 31 conforms to the shape of the connecting rod 2, improving the stability of the connection between the slot 3 and the connecting rod 2. The arc angle of the slot 31 cross-section is greater than 180°, ensuring that the connecting rod 2 can be engaged with the slot 31 without slipping out.

[0029] Preferably, along the radial direction of the slot 31, an elastic groove 34 is formed at the end of the card holder 3 near the suction tube 5. One end of the elastic groove 34 is connected to the slot 31, and the other end of the elastic groove 34 is connected to the outer surface of the card holder 3. The local stiffness of the elastic groove 34 is reduced, which makes it easier to open the slot 31 and insert the connecting rod 2 into the slot 31, and facilitates the installation of the suction tube 5 fixing bracket.

[0030] Please refer to Figure 1 and Figure 2 The mounting base 3 has a sleeve hole 32, through which it is sleeved onto the connecting rod 2. The sleeve hole 32 and the connecting rod 2 can have an interference fit. In some embodiments, the mounting base 3 has a second fastening hole 35. The second fastening hole 35 can be a threaded hole. Bolts, screws, or other threaded fasteners known in the prior art are screwed into the second fastening hole 35 and press against the connecting rod 2 to enhance the connection strength between the mounting base 3 and the connecting rod 2.

[0031] Preferably, a support groove 33 is formed through the card holder 3 along the axial direction of the suction tube 5. The support groove 33 connects to the sleeve hole 32. At the position of the support groove 33, the local rigidity of the card holder 3 is reduced, making it easier for the operator to open the card groove 31 and engage the connecting rod 2 within the card groove 31, thus facilitating the installation of the suction tube 5 fixing bracket.

[0032] Please refer to Figure 1 and Figure 2 A support block 4 is installed inside the support groove 33. One end of the support block 4 has a first arc groove (not shown in the figure) that contacts the connecting rod 2, and the other end of the support block 4 has a second arc groove (not shown in the figure) that contacts the suction tube 5. The support block 4 abuts against the connecting rod 2 and the suction tube 5, improving the stability of the suction and fixation of the cotton in the slot 31.

[0033] Preferably, a limiting protrusion 51 is provided on the outer surface of the suction tube 5 along the axial direction of the suction tube 5. A limiting groove 41 is provided on the support block 4 in the second arc groove for the limiting protrusion 51 to be engaged, so as to restrict the suction tube 5 from rotating around its own axis and further improve the stability of the suction tube 5.

[0034] The assembly process of this utility model is as follows: Corresponding to the number of suction tubes 5, a corresponding number of retainers 3 are fitted onto the connecting rod 2, and then two fixing blocks 1 are fitted onto both ends of the connecting rod 2. The connecting rod 2 passes through the retainer 3 along the fitting hole 32 and through the fixing block 1 along the fixing hole 12. Fasteners pass through the fixing block 1 along the connecting hole 11 and connect to the roller seat 6, connecting the fixing block 1 and the roller seat 6. The action is repeated to fix the two fixing blocks 1 onto the roller seat 6, at which point the connecting rod 2 and retainer 3 are also set on the roller seat 6. Threaded connectors are screwed into the first fastening hole 14 and abut against the connecting rod 2 to fix the connecting rod 2 and the fixing block 1. The support block 4 is moved into the support groove 33, and the first arc groove abuts against the connecting rod 2. Then, the assembler opens the retainer groove 31 and inserts the suction tube 5 into the retainer groove 31, and the limiting protrusion 51 is inserted into the limiting groove 41. After the assembler adjusts the suction tube 5 to face the yarn, the threaded connector is screwed into the second fastening hole 35 and abuts against the connecting rod 2, fixing the connecting rod 2 and the retaining seat 3. The above fixing actions between the suction tube 5 and the retaining seat 3, and between the retaining seat 3 and the connecting rod 2 are repeated to complete the installation of the suction tube 5 fixing bracket.

[0035] 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.

[0036] 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.
