Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of ring spinning machines, specifically relating to a flat plate sealing device for ring spinning machines. Background Technology
[0002] During the operation of a ring spinning frame, the fiber sliver is stretched by the front, middle, and rear rollers in the drafting zone, making it longer and thinner. It then passes through a twisting and winding mechanism to form a stable yarn. The power source for the drafting zone is located in the head and tail housings of the machine, typically using gear transmission or a servo motor. To ensure transmission efficiency and motor heat dissipation, the drafting zone must be kept clean and unobstructed. The drafting rollers pass through the side walls of the housing, forming the drafting working sections on both sides of the ring spinning frame. Due to the different positional requirements of the front, middle, and rear rollers, clearance holes are provided on the side walls of the housing. To facilitate adjustments to the front, middle, and rear rollers, these clearance holes are much larger than the cross-section of the drafting roller body, resulting in internal and external communication within the head or tail housing.
[0003] Currently, protruding drafting sealing plates are commonly used to seal the heads or tails of spinning machines. These plates protrude from the drafting sealing wall plates, and brushes or strips of hard rubber are used as sealing materials between the drafting sealing wall plates and the drafting rollers. However, brush seals require a sheet metal or aluminum base for fixation, the brushes are prone to loosening or falling off, and the cost is relatively high. Hard rubber seals are greatly affected by factors such as temperature and humidity and are prone to aging. In addition, when the roller's output shaft passes through the brush or strip of hard rubber, the plate may warp, affecting the sealing effect and allowing fly waste to easily enter the housing, thereby damaging internal components and increasing the complexity of cleaning work. At the same time, because the brushes or hard rubber plates occupy a lot of space, the speed measuring brackets of the middle and rear rollers can only be detected by Hall sensors installed on the roller slides, which is inconsistent with the detection method of proximity switches used for the front rollers, making adjustment and maintenance difficult. Utility Model Content
[0004] The purpose of this utility model is to provide a flat plate sealing device for a ring spinning machine, which can improve the sealing effect and prevent fly shavings from entering the housing at the head or tail of the ring spinning machine, thereby preventing damage to the internal parts of the housing.
[0005] The technical solution of this utility model is as follows: a flat sealing device for a ring spinning frame, disposed on the drafting wall plate of the spinning frame. The drafting sealing wall plate is disposed on the head or tail of the spinning frame, and mounting holes are symmetrically opened on the drafting sealing wall plate. A flat sealing device is provided at each mounting hole. The flat sealing device includes:
[0006] The support assembly includes an upper support plate and a lower support plate, both of which are disposed in the mounting holes of the tension sealing wall panel, and the upper support plate and the lower support plate are combined to form a flat plate that matches the mounting holes, and a placement hole is provided between the upper support plate and the lower support plate.
[0007] The pressure plate assembly includes an upper pressure baffle and a lower pressure baffle, wherein the upper pressure baffle is connected to an upper support plate and the lower pressure baffle is connected to a lower support plate;
[0008] A sealing assembly includes a first sealing plate and a second sealing plate. The first sealing plate is disposed on one side of the placement hole, and the second sealing plate is disposed on one side of the first sealing plate. Both the first sealing plate and the second sealing plate are pressed against one side of the support assembly by a pressure plate assembly. The first sealing plate and the second sealing plate are provided with multiple stretching holes.
[0009] The detection bracket assembly includes a first detection bracket and a second detection bracket. The first detection bracket is located on one side of the lower support plate and has a front roller detection hole. The second detection bracket is located on one side of the lower clamping baffle and has a middle roller detection hole and a rear roller detection hole. A proximity switch is provided in each of the front roller detection hole, the middle roller detection hole, and the rear roller detection hole.
[0010] Furthermore, both the first sealing plate and the second sealing plate are made of felt with a thickness of 5mm.
[0011] Furthermore, the second sealing plate includes a front sealing plate and a rear sealing plate, and there is a gap between the front sealing plate and the rear sealing plate.
[0012] Furthermore, the plurality of drawing holes respectively include a front roller elongated hole, a middle roller drawing hole, a rear roller elongated hole, a front roller drawing hole, a middle roller adjusting hole, and a rear roller drawing hole; wherein the front roller elongated hole, the middle roller drawing hole, and the rear roller elongated hole are sequentially opened at 45° on the first sealing plate, and the front roller drawing hole, the middle roller adjusting hole, and the rear roller drawing hole are sequentially opened at 45° on the second sealing plate, and the middle roller adjusting hole is located in the gap formed by the front sealing plate and the rear sealing plate.
[0013] Furthermore, a front roller is installed within the elongated hole and the drafting hole of the front roller, with a clearance fit between the drafting hole and the front roller; a middle roller is installed within the drafting hole and the adjusting hole of the middle roller, with a clearance fit between the drafting hole and the middle roller; a rear roller is installed within the elongated hole and the drafting hole of the rear roller, with a clearance fit between the drafting hole and the rear roller; the front roller, middle roller, and rear roller are arranged sequentially at 45° on the flat sealing device; a front roller detection wheel, a middle roller detection wheel, and a rear roller detection wheel are respectively installed on the front roller, middle roller, and rear roller, and the front roller detection wheel, middle roller detection wheel, and rear roller detection wheel are respectively located above the front roller detection hole, middle roller detection hole, and rear roller detection hole.
[0014] Furthermore, the second detection bracket is installed at a 45° angle to the horizontal direction on the side surface of the lower clamping baffle.
[0015] Furthermore, both the middle roller detection hole and the rear roller detection hole are oblong holes. The positions of the internal proximity switches are adjusted through the middle roller detection hole and the rear roller detection hole so that the two proximity switches correspond to the positions of the middle roller detection wheel and the rear roller detection wheel, respectively.
[0016] The beneficial effects of this utility model are as follows: The placement hole is sealed by a first and second sealing plate made of 5mm thick felt. The felt first and second sealing plates are not easily aged due to factors such as temperature and humidity. Simultaneously, the upper and lower clamping baffles press the first and second sealing plates firmly against the side walls of the upper and lower support plates, preventing them from slipping or falling out of the placement hole. The first and second sealing plates are stacked, and the elongated hole of the front roller and the drawing hole of the front roller are also connected. The staggered arrangement of the elongated hole and the drafting hole of the rear roller enhances the sealing performance of the sealing device, preventing fly debris from entering the front or rear box, reducing the workload of cleaning the front or rear box, and extending the maintenance cycle of the front or rear box. By installing proximity switches in the detection holes of the front roller, middle roller, and rear roller respectively, the rotational speed of the front roller, middle roller, and rear roller is detected by the three proximity switches. The unified signal detection element achieves consistency in rotational speed detection, which facilitates the inspection and maintenance of the drafting roller by the staff.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.
[0025] When using brushes or strip-shaped rigid rubber sheets as sealing materials between the stretch sealing wall panel and the stretching roller, the brush seal requires a sheet metal or aluminum base for fixation, making the brush prone to loosening or falling off, and is also costly. Rigid rubber sheet seals are greatly affected by factors such as temperature and humidity, and are prone to aging. Moreover, when the roller's output shaft passes through the brush or strip-shaped rigid rubber sheet, it may cause the sheet or brush to warp, affecting the sealing effect and allowing fly shavings to easily enter the housing, thereby damaging internal components and increasing the complexity of cleaning work. At the same time, because the brush or rigid rubber sheet occupies a lot of space, the speed measuring brackets of the middle roller and the rear roller can only be detected by Hall sensors installed on the roller slide, which is inconsistent with the detection method of proximity switches used for the front roller, making adjustment and maintenance difficult.
[0026] like Figures 1 to 4 As shown, a flat sealing device for a ring spinning frame is installed on the drafting wall plate 1 of the spinning frame. The drafting sealing wall plate 1 is installed on the head or tail of the spinning frame. The drafting sealing wall plate 1 has symmetrical mounting holes, and a flat sealing device is installed at each mounting hole. The flat sealing device includes: a support assembly 2, a pressure plate assembly 3, a sealing assembly 4, and a detection bracket assembly 5.
[0027] Among them, such as Figure 1 As shown, the support assembly 2 includes an upper support plate 21 and a lower support plate 22. Both the upper support plate 21 and the lower support plate 22 are disposed in the mounting holes of the stretch sealing wall panel 1. After the upper support plate 21 and the lower support plate 22 are combined, they form a flat plate that matches the mounting holes. A placement hole is provided between the upper support plate 21 and the lower support plate 22.
[0028] Based on the above embodiments, the upper support plate 21 and the lower support plate 22 are installed at the mounting holes of the drafting sealing wall 1 to form a regular flat sealing structure. No protrusions are formed on the drafting sealing wall 1, which not only improves the appearance quality of the head or tail box of the ring spinning machine, but also reduces the floor space occupied by the drafting sealing wall 1.
[0029] In this embodiment, as Figure 2 and Figure 4 As shown, the pressure plate assembly 3 includes an upper pressure baffle 31 and a lower pressure baffle 32. The upper pressure baffle 31 is connected to the upper support plate 21, and the lower pressure baffle 32 is connected to the lower support plate 22.

Both the first sealing plate 41 and the second sealing plate 42 are made of felt with a thickness of 5mm. The first sealing plate 41 is located on one side of the placement hole, and the second sealing plate 42 is located on one side of the first sealing plate 41. Both the first sealing plate 41 and the second sealing plate 42 are pressed against one side of the support assembly 2 by the pressure plate assembly 3. The second sealing plate 42 includes a front sealing plate 42-1 and a rear sealing plate 42-2. There is a gap between the front sealing plate and the rear sealing plate.
[0031] Based on the above embodiments, the placement hole is sealed by the first sealing plate 41 and the second sealing plate 42 made of 5mm thick felt. The first sealing plate 41 and the second sealing plate 42 made of felt are not easily affected by factors such as temperature and humidity and will not age. At the same time, the first sealing plate 41 and the second sealing plate 42 are pressed against the side walls of the upper support plate 21 and the lower support plate 22 by the upper pressing baffle 31 and the lower pressing baffle 32, so as to prevent the first sealing plate 41 and the second sealing plate 42 from slipping off or falling off from the placement hole.
[0032] In this embodiment, as Figure 5 As shown, the first sealing plate 41 and the second sealing plate 42 are provided with a plurality of drawing holes 43, which respectively include a front roller elongated hole 43-1, a middle roller drawing hole 43-2, a rear roller elongated hole 43-3, a front roller drawing hole 43-4, a middle roller adjusting hole 43-5, and a rear roller drawing hole 43-6; wherein the front roller elongated hole 43-1, the middle roller drawing hole 43-2, and the rear roller elongated hole 43-3 are opened at 45° on the first sealing plate 41, and the front roller drawing hole 43-4, the middle roller adjusting hole 43-5, and the rear roller drawing hole 43-6 are opened at 45° on the second sealing plate 42, and the middle roller adjusting hole 43-5 is located at the gap formed by the front sealing plate 42-1 and the rear sealing plate 42-2.
[0033] The front roller is housed in the elongated bore 43-1 and the drafting bore 43-4 of the front roller, with the drafting bore 43-4 and the front roller having a clearance fit. The middle roller is housed in the drafting bore 43-2 and the adjusting bore 43-5 of the middle roller, with the drafting bore 43-2 and the middle roller having a clearance fit. The rear roller is housed in the elongated bore 43-3 and the drafting bore 43-6 of the rear roller, with the drafting bore 43-6 and the rear roller having a clearance fit. The front roller, middle roller, and rear roller are arranged sequentially at a 45° angle on this flat sealing device.
[0034] Based on the above embodiments, the first sealing plate 41 and the second sealing plate 42 are stacked, and the front roller elongated hole 43-1 and the front roller drawing hole 43-4, as well as the rear roller elongated hole 43-3 and the rear roller drawing hole 43-6, are staggered to enhance the sealing performance of the sealing device 4. The first sealing plate 41 is an integral structure, and the front roller elongated hole 43-1 and the rear roller elongated hole 43-3 are both elongated holes. The second sealing plate 42 is a split structure, which is connected to the rear sealing plate 42-1 by the front sealing plate 42-1. The gap between plates 42-2 allows for adjustment of the positions of the front roller drawing hole 43-4 and the rear roller drawing hole 43-6. The front roller elongated hole 43-1, the middle roller drawing hole 43-2, and the rear roller elongated hole 43-3 are sequentially opened at 45° on the first sealing plate 41. The front roller drawing hole 43-4, the middle roller adjusting hole 43-5, and the rear roller drawing hole 43-6 are sequentially opened at 45° on the second sealing plate 42, enabling the front roller and the rear roller to be finely adjusted in a direction at a 45° angle to the horizontal plane.

The second detection bracket 52 has a middle roller detection hole 54 and a rear roller detection hole 55. A proximity switch 56 is provided in each of the front roller detection hole 53, the middle roller detection hole 54, and the rear roller detection hole 55.
[0036] Among them, the front roller, the middle roller and the rear roller are respectively provided with a front roller detection wheel 11, a middle roller detection wheel 12 and a rear roller detection wheel 13, which are respectively located above the front roller detection hole 53, the middle roller detection hole 54 and the rear roller detection hole 55.
[0037] Specifically, both the middle roller detection hole 54 and the rear roller detection hole 55 are oblong holes. By adjusting the positions of the internal proximity switches 56 through the middle roller detection hole 54 and the rear roller detection hole 55, the two proximity switches 56 correspond to the positions of the middle roller detection wheel 12 and the rear roller detection wheel 13, respectively.
[0038] Based on the above embodiments, proximity switches 56 in the front roller detection hole 53, middle roller detection hole 54, and rear roller detection hole 55 respectively detect the front roller detection wheel 11, middle roller detection wheel 12, and rear roller detection wheel 13, thereby detecting the rotational speed of the front roller, middle roller, and rear roller. At the same time, according to the change in the distance between the middle roller and the rear roller, the positions of the proximity switches 56 inside the middle roller detection hole 54 and the rear roller detection hole 55 are adjusted respectively. The detection of the rotational speed of the front roller, middle roller, and rear roller is all performed through proximity switches 56. The unified signal detection element achieves consistency in the detection of the rotational speed of the front roller, middle roller, and rear roller.
