Description

Technical Field

[0001] The utility model belongs to the technical field of ring spinning frames, and in particular relates to a novel drafting and sealing device for a ring spinning frame. Background Art

[0002] The ring spinning frame is a spinning machine that drafts, twists and winds semi-finished roving into spun yarn in the spinning process. As an indispensable functional mechanism in the spinning process, the drafting roller plays a vital role. The drafting rollers include the front roller, the middle roller and the rear roller, and on the ring spinning frame, the drafting rollers are symmetrically arranged on both sides of the ring spinning frame; the power source of the drafting rollers is located in the front box and the rear box of the ring spinning frame, and the drafting rollers pass through the side walls of the box to form a drafting working part on both sides of the ring spinning frame. Since the positions of the front roller, the middle roller and the rear roller need to be adjusted according to actual production needs, the clearance holes opened on the side walls of the box for the drafting rollers to pass through will be much larger than the cross-section of the drafting roller body, which will make the inside of the box connected to the outside world, and the flying flowers and other substances generated during the operation of the ring spinning frame will enter the box, thereby causing damage to the precision instruments in the box.

[0003] Therefore, the existing ring spinning machine installs a harder plastic film plate around the give way hole, and processes and trims the plastic film plate into strips and spreads it at the intersection of the drafting roller and the plastic film to achieve the best sealing effect. However, the sealing effect of this design method is not good, and the strip-shaped plastic film is prone to deformation, which further weakens its sealing effect, making it easy for more flying fibers to enter the box body, causing damage to the device components in the box body, and also increasing the workload of the staff in cleaning the flying fibers in the box body. Utility Model Content

[0004] In view of this, the present application provides a new drafting sealing device for a ring spinning machine.

[0035] So far, if Figure 4 As shown, the first sealing box 201 and the second sealing box 202 together form a sealing box body, and the first working part 204 and the second working part 207 together form a mounting cavity inside the sealing box body.

[0036] Based on the above embodiment, the appearance of the sealing component 2 is composed of a regular flat plate structure in the first sealing box 201 and the second sealing box 202, so that the appearance quality of the stretching sealing device is improved.

[0039] Based on the above embodiment, when the first rubber sheet 3 and the second rubber sheet 4 are stacked in sequence in the direction away from the travel hole, and at the same time, the first rear roller limiting hole 301 and the second rear roller limiting hole 401 are installed in cooperation with the rear roller; the first middle roller limiting hole 302 and the second middle roller limiting hole 402 are installed in cooperation with the middle roller; the first front roller limiting hole 303 and the second front roller limiting hole 403 are installed in cooperation with the front roller, the sealing between the box and the drafting roller in the ring spinning machine is improved, and the first rear roller limiting hole 301 and the first front roller limiting hole 303 are both long holes, and the second middle roller limiting hole 302 and the second middle roller limiting hole 402 are installed in cooperation with the middle roller. The roller limit hole 402 is set to a fracture shape, so that each roller in the drafting roller can be fine-tuned in a direction at an angle of 45° to the horizontal plane, thereby meeting the requirement for adjusting the spacing of the drafting rollers, which reflects the practicality of the utility model. In addition, the thickness of the first rubber sheet 3 and the second rubber sheet 4 are both 5 mm, and the outer contour shapes of the first rubber sheet 3 and the second rubber sheet 4 are the same as the outer contour shapes of the through holes. The outer contour areas of the first rubber sheet 3 and the second rubber sheet 4 are both larger than the outer contour areas of the through holes, which ensures that the through holes are covered while avoiding waste of materials. The installation state is as follows: Figure 5 shown.

[0040] In the technical solution, a pressing assembly is used to press the first rubber sheet 3 and the second rubber sheet 5 which are sequentially stacked in a direction away from the through hole onto the through hole.

[0041] Among them, Figure 3 , Figure 6 As shown, the clamping assembly includes an "L"-shaped first clamping member 501 and a linear second clamping member 502. The first clamping member 501 includes an integrally arranged first clamping portion 503 and a first connecting portion 504. During installation, the first clamping portion 503 is buckled above the second rubber plate 4, and the first clamping member 501 is installed on the second sealing box 202 through the cooperation of the first connecting portion 504 and the bolt; the second clamping member 502 includes an integrally arranged second clamping portion 505 and a second connecting portion 506. During installation, the second clamping portion 505 is buckled above the second rubber plate 4, and the second clamping member 502 is installed on the first sealing box 201 through the cooperation of the second connecting portion 506 and the bolt.

[0042] Based on the above embodiment, the arrangement of the clamping assembly enables the first rubber plate 3 and the second rubber plate 4 to stably perform a sealing function, and when the clamping assembly is installed in the installation cavity, the first clamping portion 503 and the second clamping portion 505 do not interfere with the second rear roller limiting hole 401, the second middle roller limiting hole 402, and the second front roller limiting hole 403, that is, the clamping assembly does not interfere with the drafting roller, ensuring its normal operation. The specific installation state is as follows: Figure 6 shown.

[0043] Specifically, when the drafting sealing device provided by the utility model is used to provide a seal between the box body and the drafting roller, the drafting sealing wall plate 1 is first installed on the box body, and then the sealing box bodies of the two sets of sealing components 2 are respectively installed on the two installation holes 103, and the drafting rollers are placed in the passage holes. After the spacing between the drafting rollers is adjusted, the first rubber plate 3 and the second rubber plate 4 are placed in the installation cavity in sequence, and each limit hole is installed in correspondence with each roller. The first rubber plate 3 The installation reference is the first middle roller limiting hole 302, and the installation reference of the second rubber plate 4 is the second rear roller limiting hole 401 and the second front roller limiting hole 403. At this point, the sealing installation of the first rubber plate 3 and the second rubber plate 4 is completed. Since the first rubber plate 3 and the second rubber plate 4 are made of rubber, when they are sleeved on the outer wall of the drafting roller, one side of each limiting hole in the first rubber plate 3 and the second rubber plate 4 can be cut off, and each roller can be placed in a limiting hole using the cut end.

[0044] After completing the sealing installation of the first rubber sheet 3 and the second rubber sheet 4, the first pressing part 503 and the second pressing part 505 in the pressing assembly are used to press the first rubber sheet 3 and the second rubber sheet 5 stacked in sequence along the direction away from the passage hole onto the passage hole, and the first connecting part 504 and the second sealing box 202, and the second connecting part 506 and the first sealing box 201 are used to fix them. At this point, the installation of the drafting sealing device is completed. The device greatly improves the sealing between the drafting roller and the box body, avoids the problem that the accumulation of flying flowers in the box body easily causes damage to the device components and increases the cleaning workload of the staff. While having a beautiful structure, it can also take into account the adjustment of the spacing between the drafting rollers, reflecting the practicality of the utility model.

[0045] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
