Description

Technical Field

[0001] This utility model relates to the field of textile machinery technology, specifically to an automatic yarn clearing device for spinning machine spindles. Background Technology

[0002] In the production of ring spinning machines used in textile production, some tail yarn often gets tangled in the spindle feet during the production process. Gradually, the tail yarn accumulates more and more at the lower end of the spindle, covering the knurling and causing the lower end of the spindle to lose friction. As a result, when the yarn is doffed later, it slips and cannot be wound around, affecting the spinning production.

[0003] Chinese utility model patent application number 201821635303.0 discloses "a yarn cleaning device for a spinning machine spindle". The above technical solution utilizes an adjustment mechanism, which can control a servo driver to turn on a servo motor through a PLC controller, thereby driving a linear module through a coupling. This allows the slider to slide back and forth on the linear module, adjusting the position of the cutter, which facilitates the cleaning of yarn on the spindle. This avoids the need for one-to-one installation of cutters on each spindle, saving costs.

[0004] However, in actual use, when using a blade to clean impurities wrapped around the surface of the spindle, the blade will collide with the spindle, which will not only damage its surface, but also affect the stability of the spindle, thus affecting the production quality of the yarn and further increasing the amount of miscellaneous yarn entanglement.

[0005] Therefore, an automatic yarn clearing device for spinning machine spindles is proposed. Utility Model Content

[0006] To address the problems existing in the prior art, this utility model provides an automatic yarn clearing device for spinning machine spindles.

[0007] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0008] An automatic yarn clearing device for spinning machine spindles includes a textile machine mounting frame and multiple evenly arranged spindles rotating above it. A positioning plate is provided on the textile machine mounting frame, and multiple evenly arranged U-shaped connecting plates are slidably mounted on the positioning plate. A blade is provided on one side of each U-shaped connecting plate. A fixing plate corresponding to the position of the U-shaped connecting plates is provided on the positioning plate, and a telescopic rod is provided on one side of the fixing plate.

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0022] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0023] It should be noted that similar reference numerals and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures. Furthermore, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0024] In the description of the embodiments of this utility model, it should be noted that the terms "inner", "outer", "upper", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, or the orientation or positional relationship in which the utility model product is usually placed when in use. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0025] like Figure 1-4As shown, an automatic yarn clearing device for spinning machine spindles includes a spinning machine mounting frame 1 and multiple evenly arranged spindles 3 rotating above it. A positioning plate 2 is provided on the spinning machine mounting frame 1, and multiple evenly arranged U-shaped connecting plates 6 are slidably mounted on the positioning plate 2. A blade 601 is provided on one side of each U-shaped connecting plate 6. A fixing plate 8 corresponding to the position of the U-shaped connecting plate 6 is provided on the positioning plate 2, and a telescopic rod 801 is provided on one side of the fixing plate 8. A spring 802 is sleeved on the telescopic rod 801. The U-shaped connecting plates 6 are connected to the telescopic ends of the telescopic rod 801. A driving component 7 for driving the U-shaped connecting plates 6 to slide is provided on the positioning plate 2. The driving component 7 includes a second motor 701 and an eccentric wheel 702. Specifically, the positioning plate 2 can be fixed to the spinning machine by snap-fit ​​or bolt connection. The fixing method on the loom mounting frame 1 does not affect the innovation of this technical solution, so it is not limited here. Under the elastic force of the spring 802, the U-shaped connecting plate 6 can be pressed and fitted with the eccentric wheel 702. When the eccentric wheel 702 rotates, it can also drive the U-shaped connecting plate 6 to move back and forth. Therefore, for the yarn that should be wound around the bottom of the spindle, the yarn will be wound around one side of the blade 601. During its back and forth movement, the yarn can be cut. The elastic force of the spring 802 is large enough and the blade 601 is sharp enough, so the spring 802 can be guaranteed to rebound. When the U-shaped connecting plate 6 is closest to the spindle 3, it will not touch the spindle 3, so as to avoid damage to the spindle 3 and also avoid collision with it, thus affecting its rotational stability.

[0026] like Figure 3-4 As shown, the positioning plate 2 is equipped with a cleaning component 4 for automatically collecting the cut yarn. The cleaning component 4 includes a suction hood 401, a filter screen 402, a connecting pipe 403, and a suction head 404. Specifically, the suction hood 401 is connected to a dust collection device, such as an exhaust fan. Under the action of the wind, the cut yarn can be drawn into the interior of the suction hood 401.

[0027] like Figure 3-4 As shown, the filter screen 402 is disposed inside the suction hood 401, the suction head 404 is fixedly connected to the U-shaped connecting plate 6, and the suction head 404 and the suction hood 401 are connected by a connecting pipe 403, which is a telescopic design; specifically, the suction head 404 can move with the U-shaped connecting plate 6, and the telescopic design of the connecting pipe 403 avoids interfering with the movement of the U-shaped connecting plate 6.

[0028] like Figure 3-4As shown, the suction hood 401 is provided with an auxiliary component 5 for assisting in cleaning the filter screen 402. The auxiliary component 5 includes a slide rail 501, a first motor 502, a reciprocating screw 503, a slider 504, and a scraper 505. Specifically, the slide rail 501 and the suction hood 401 are connected, so the slider 504 and the scraper 505 can be connected. The reciprocating screw 503 is located above the suction hood 401. The sucked-in lint impurities can be blocked on one side of the filter screen 402 under the action of suction, and will not float upward. Therefore, it can also prevent lint impurities from getting tangled on its surface and affecting its normal use.

[0029] like Figure 3-4 As shown, the reciprocating screw 503 is connected to the main shaft end of the first motor 502. The slider 504 is slidably disposed inside the slide rail 501 and its thread is sleeved on the reciprocating screw 503. The scraper 505 is connected to the slider 504 and the scraper 505 is in contact with the surface of the filter screen 402. Specifically, the operation of the first motor 502 can drive the reciprocating screw 503 to rotate. The rotation of the reciprocating screw 503 can drive the slider 504 to slide back and forth inside the slide rail 501. Therefore, it can accumulate the lint and other impurities adsorbed on the surface of the filter screen 402 to both sides, so as to avoid the filter screen 402 from being blocked and affecting its impurity removal efficiency. The impurity suction cover 401 can be provided with a movable door to facilitate the cleaning of the accumulated lint and impurities. This will not be described in detail here.

[0030] like Figure 3-4 As shown, the eccentric wheel 702 is connected to the main shaft end of the second motor 701. When the long end of the eccentric wheel 702 is pressed against the U-shaped connecting plate 6, the U-shaped connecting plate 6 is closest to the spindle 3, and vice versa. Specifically, the operation of the second motor 701 can drive the eccentric wheel 702 to rotate. Under the compression of the spring 802, the U-shaped connecting plate 6 can be pressed and fitted against the eccentric wheel 702. When the eccentric wheel 702 rotates, it can also drive the U-shaped connecting plate 6 to move back and forth. Therefore, for the yarn that should be wound around the bottom of the spindle, the yarn will be wound around one side of the blade 601. During its back and forth movement, the yarn cutting function can be achieved.

[0031] In summary: the positioning plate 2 is fixed on the textile machine mounting frame 1, and then the blades 601 correspond to the bottom of one of the two spindles 3. The second motor 701 can drive the eccentric wheel 702 to rotate. Under the compression of the spring 802, the U-shaped connecting plate 6 can be pressed and adhered to the eccentric wheel 702. When the eccentric wheel 702 rotates, it can also drive the U-shaped connecting plate 6 to move back and forth. Therefore, for the yarn that should be wound around the bottom of the spindle, the yarn will be wound around one side of the blade 601. During its back and forth movement, the yarn can be cut. The cut yarn impurities can be adsorbed by the impurity removal component 4. The impurities adsorbed into the impurity suction hood 401 can be blocked and filtered by the filter screen 402. Under the action of the auxiliary component 5, the scraper 505 can push the wool and other impurities adsorbed on the surface of the filter screen 402 to both sides, so that they accumulate to both sides, avoiding the filter screen 402 from being blocked and affecting its impurity removal efficiency.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
