Description

Technical Field

[0001] The present invention relates to the technical field of combing machines, in particular to a driving device for rapidly raising fiber beards when the nippers of a cotton combing machine are opened and a driving method for rapidly raising fiber beards when the nippers of a cotton combing machine are opened. Background Art

[0002] As combing efficiency increases, the speed of the combing machine and the quality requirements of the combed strips also increase accordingly. As a result, the problem of rapid, stable and high-quality splicing of new and old combed fibers in the combing process becomes prominent, especially the problem of complete and timely lifting of the fiber beards at the moment of splicing, which has become a technical problem that urgently needs to be effectively solved.

[0003] Currently, existing technologies for raising fiber clumps rely solely on the natural stretching of the bent fibers during the comber's nipper opening. This stretching time requires precise timing to allow more time for the combing and splicing process. However, as machine speeds continue to increase, this method becomes unsustainable due to the significantly shortened combing cycle.

[0004] Therefore, it is urgent to invent a fiber beard clump fast lifting drive device and method when the combing machine nipper is open, which actively promotes the fiber beard clump to respond quickly at the high speed of the combing machine and prompts it to complete the lifting in a timely and sufficient manner.

[0005] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of the present invention, and therefore may include information that does not constitute prior art known to ordinary technicians in this field. Summary of the Invention

[0007] According to one aspect of the present invention, a driving device for rapidly raising the fiber bundle when the nipper of a cotton combing machine is opened is provided, comprising an air flow driving component, the air flow driving component being installed on the cylinder assembly. α In the phase position, an airflow cavity is formed between the airflow driving component and the cylinder assembly, and the airflow cavity is matched with the nipper opening.

[0008] In one embodiment of the driving device, the angle between the line connecting the outermost key point of the airflow driving component to the axis of the cylinder and the vertical line passing through the axis of the cylinder when the upper and lower nippers of the cotton combing machine are opened is α , where 0°≤ α≤70°. The radial distance between the outermost point of the airflow drive component and the axis of the cylinder is less than the vertical distance between the bottom surface of the lower nipper and the axis of the cylinder. The airflow drive component includes a protrusion, and the linear distance between the two ends of the protrusion along the circumference of the cylinder is A, where 0mm<A≤40mm. Along the direction of cylinder rotation, the front end of the protrusion is the outermost key point of the airflow drive component.

[0009] In one implementation of the driving device, both end faces of the airflow driving component are closed along the axial direction of the cylinder.

[0010] In one implementation of the driving device, the airflow driving component is a convex folding plate component, which includes a convex folding plate, a connecting plate and a mounting screw assembly I. The convex folding plate includes a front part, a convex part and a tail part, and the front part and the convex part are connected by an inclined guide plate. The inclined guide plate is set as an inclined folding plate or an inclined curved plate. The tail part is tangent to or not connected to the cylinder cover. The connecting plate is connected to the front and tail of the convex folding plate. The mounting screw assembly I passes through the convex folding plate and the connecting plate and is installed on the cylinder cover.

[0011] The lining plate includes a first flat plate and a second flat plate. The first flat plate is connected to the front portion of the convex folding plate. The second flat plate is fixedly connected to the rear portion of the convex folding plate by screws. The angle between the first flat plate and the second flat plate is equal to the angle between the front portion of the convex folding plate and the rear portion of the convex folding plate.

[0012] The rear part of the needle plate seat of the cylinder is located in the counterclockwise direction of the convex folding plate component. There is a phase difference space between the convex part of the convex folding plate component and it. This phase difference space forms an airflow cavity, and the airflow cavity cooperates with the clamp opening.

[0013] The minimum radial distance between the convex part of the convex folding plate and the axis of the cylinder is greater than the maximum radial distance between the front part of the convex folding plate and the axis of the cylinder; the minimum radial distance between the convex part of the convex folding plate and the axis of the cylinder is greater than the maximum radial distance between the tail part of the convex folding plate and the axis of the cylinder.

[0014] Or the airflow driving component is a cylinder guard component, and the cylinder guard component includes an integrally formed cover and a mounting screw assembly II. The integrally formed cover is formed as one piece by a convex portion and a cylinder cover shell. The front end of the convex portion and the cylinder cover shell are connected by an inclined drainage surface, and the inclined drainage surface is set as an inclined folded surface or an inclined curved surface. The tail end of the convex portion and the cylinder cover shell are connected by a curved surface or an inclined surface. The mounting screw assembly II passes through the integrally formed cover and is installed on the cylinder shaft.

[0015] The convex portion is located outside the integral forming cover. The rear portion of the needle plate seat of the cylinder is located counterclockwise of the integral forming cover.

[0019] S1. The cylinder assembly is in operation, and the airflow drive component rotates with the rotation of the cylinder assembly, thereby forming an airflow in the airflow cavity that drives the fiber beard cluster to rise;

[0020] S2. When the nipper is just opened, the airflow drives the components to rotate to the cylinder assembly. α In the phase position, as the opening of the nipper gradually becomes larger, the airflow actively pushes the fiber beard cluster at the opening of the nipper to rise quickly.

[0021] The present invention has the following technical effects:

[0022] The present invention provides an air flow driving component at a specific phase of the cylinder shaft.

[0032] To make the above-mentioned objects, features, and advantages of the present invention more readily apparent, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings. The following description sets forth numerous specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art may make similar modifications without departing from the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0033] In the description of the present invention, it should be understood that the terms "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as limiting the present invention.

[0034] In the embodiments of the present invention, unless otherwise expressly specified or limited, the terms "installed," "connected," "connected," "fixed," etc. should be understood in a broad sense. For example, they may refer to fixed connection, detachable connection, or integration; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; internal communication between two components or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in the embodiments of the present invention based on specific circumstances.

[0035] Example 1:

[0036] like Figure 1-3 As shown, a driving device is provided for quickly raising the fiber bundle when the nipper of a cotton combing machine is opened.

[0037] like Figure 1 As shown, the driving device includes an airflow driving component, which is a convex folding plate component. Specifically, the convex folding plate component includes a convex folding plate 1, a lining plate 2 and a mounting screw assembly I3.

[0038] The convex folding plate 1 includes a front part, a convex part and a tail part. Figure 1 and 2 In the embodiment, the front portion is located at the upper left corner of the convex folding plate 1, and the tail portion is located at the lower right corner of the convex folding plate 1; the front portion and the convex portion are connected by an inclined guide plate, which is configured as an inclined folding plate or an inclined curved plate. It should be noted that when the inclined guide plate is an inclined folding plate, the folding angle of the inclined folding plate is an obtuse angle, and when the inclined guide plate is an inclined curved plate, the curved surface of the inclined curved plate is an outward convex curved surface; the convex portion and the tail portion are fixedly connected. It should be noted that in this embodiment, the front portion, the inclined guide plate, the convex portion, and the tail portion are integrally formed, and the convex portion is preferably a flat plate.

[0039] The connecting plate 2 is connected to the front and rear of the convex folding plate 1. Specifically, the connecting plate 2 includes a first flat plate and a second flat plate.

[0040] The first flat panel is connected to the front portion of the convex folding panel 1 .

[0041] The first flat plate, the inclined guide plate and the convex portion form an inner cavity. It should be noted that the two ends of the inner cavity are closed along the length direction of the inner cavity. In order to save materials, simplify the structure and reduce the overall weight, the convex folding plate 1 in this embodiment is provided with an inner cavity, but the solidification of the inner cavity of the convex folding plate 1 is still within the scope of protection of the present invention.

[0042] The second flat plate and the tail of the convex folding plate 1 are fixedly connected by screws.

[0043] Therefore, the angle between the first planar plate and the second planar plate is equal to the angle between the front portion of the convex folding plate 1 and the rear portion of the convex folding plate 1 .

[0044] like Figure 2 As shown, the convex flap assembly is installed on the cylinder assembly α Phase position. The cylinder assembly includes a cylinder cover, a cylinder shaft and a cylinder. The cylinder cover and the cylinder are both mounted on the cylinder shaft. The cylinder shaft rotates, so the cylinder, the cylinder cover and the convex folding plate components rotate with the rotation of the cylinder shaft. At this time, the cylinder rotates counterclockwise.

[0045] Specifically, the convex folding plate component is installed on the cylinder housing. In the specific installation structure of the convex folding plate component, the mounting screw assembly I3 passes through the convex folding plate 1 and the backing plate 2 and is installed on the cylinder housing. The mounting screw assembly I3 includes a gasket and a bolt. That is, the bolt passes through the convex folding plate 1 and the backing plate 2 and is screwed into the threaded hole fixed to the cylinder housing, thereby fixing the convex folding plate component to the cylinder housing.

[0046] After the convex folding plate components are installed, the position distribution between the various structures is as follows:

[0047] The rear part of the needle plate seat of the cylinder is located in the counterclockwise direction of the convex folding plate component. There is a phase difference space between the convex part of the convex folding plate component and the convex part. This phase difference space forms an airflow cavity, and the airflow cavity cooperates with the opening of the clamp plate.

[0048] The minimum radial distance between the convex portion of the convex folding plate 1 and the axis of the cylinder is greater than the maximum radial distance between the front portion of the convex folding plate 1 and the axis of the cylinder;

[0049] The minimum radial distance between the convex portion of the convex folded plate 1 and the axis of the cylinder is greater than the maximum radial distance between the tail portion of the convex folded plate 1 and the axis of the cylinder;

[0050] Along the rotation direction of the cylinder, the front end of the convex part of the convex folding plate 1 is the outermost key point of the convex folding plate component;

[0051] The angle between the line connecting the outermost key point of the convex folding plate component to the axis of the cylinder and the vertical line passing through the axis of the cylinder when the upper and lower nippers of the cotton combing machine are opened is α , where 0°≤ α ≤70°. In this embodiment, α is 48.8°;

[0052] The tail of the convex folding plate 1 is tangent to the cylinder cover, that is, the tail of the convex folding plate 1 is just connected to the cylinder cover; or the tail of the convex folding plate 1 is almost tangent to the cylinder cover but not connected, and there is a gap of about 2mm;

[0053] Along the axial direction of the cylinder, both end surfaces of the convex folding plate component are closed, that is, both ends of the inner cavity of the convex folding plate 1 are sealed;

[0054] Along the rotation direction of the cylinder, the straight-line distance between the width of the convex part of the convex folded plate 1 and the two ends of the circumference of the cylinder is A, where 0mm<A≤40mm. In this embodiment, A is preferably 15mm.

[0055] like Figure 3 As shown in the figure, after the cylinder assembly with the convex folding plate component is installed on the combing machine, the position distribution between the various structures is as follows:

[0056] The rear of the cylinder's needle plate seat is located to the lower left of the nipper opening. During the first half of the cylinder assembly's rotation and the gradual opening of the nipper, the airflow chamber will be located to the lower right, lower, and lower left of the nipper opening. During this process, the airflow in the airflow chamber flows along the leading edge of the convex portion of the folded plate toward the nipper opening, thereby causing the fiber clump at the nipper opening to rise.

[0057] The radial distance between the outermost point of the convex folding plate component and the cylinder axis is less than the vertical distance between the bottom surface of the lower nipper and the cylinder axis, ensuring that the convex folding plate component does not interfere with the movement of the lower nipper bottom. In this embodiment, the radial distance between the outermost point of the convex folding plate component and the cylinder axis is 61.5 mm. It should be noted that in this embodiment, the outermost point of the convex folding plate component and the outermost key point of the convex folding plate component are not necessarily located at the same position. The outermost key point of the convex folding plate component is the front end of the convex portion of the convex folding plate 1. The outermost point of the convex folding plate component can be the front end, middle end, or rear end of the convex portion of the convex folding plate 1.

[0058] like Figure 3 As shown, a driving method for quickly raising the fiber beard bundle when the nipper of a cotton combing machine is opened is provided.

[0059] The driving method includes the following steps:

[0060] S1. The cylinder assembly is in operation. The convex folded plate rotates counterclockwise with the cylinder assembly, creating an airflow within the airflow chamber that drives the fiber clump upward. The convex folded plate is sealed at both ends to minimize airflow disturbance at the cylinder end.

[0061] S2. The nippers are opening. When the nippers are just opened, the convex folding plate parts rotate to the cylinder assembly. α In the phase position, α is 48.8°. Then, as the nipper opening gradually becomes larger, the fiber beard cluster rises and the airflow actively pushes the fiber beard cluster at the nipper opening to rise quickly. It should be noted that the phase α The value of is determined by the opening speed of the nipper opening and the rotation speed of the cylinder assembly.

[0062] The working process of Example 1 will be further described below:

[0063] Install the convex folding plate component and the cylinder assembly on the combing machine respectively;

[0064] When the cylinder shaft rotates and drives the cylinder to comb the fiber bundle, the upper and lower nippers of the combing machine begin to open;

[0065] When the nippers are just opened, the convex flap parts rotate to the cylinder assembly. α In the phase position, α is 48.8°, at which point the convex folding plate component is below the nipper opening;

[0066] Afterwards, the nipper opening continues the opening process;

[0067] The convex part of the convex folded plate component pushes the airflow forward as the cylinder shaft rotates, and then actively pushes up the fiber layer and the beard clumps to rise quickly. As the cylinder assembly continues to rotate, the convex part of the convex folded plate component rotates and passes just when the fiber beard clumps are about to overlap, thus completing its function;

[0068] At this time, the airflow below the fiber beard bundle is quickly drawn downward by the negative pressure of the inhalation duct to complete the splicing. Example

[0069] like Figure 4-6 As shown, a driving device is provided for quickly raising the fiber bundle when the nipper of a cotton combing machine is opened.

[0070] like Figure 4 As shown, the driving device includes an airflow driving component, which is a cylinder shield component. Specifically, the cylinder shield component includes an integrally formed cover 4 and a mounting screw assembly II5. The integrally formed cover 4 is formed integrally with the convex portion and the cylinder cover shell. The integrally formed cover 4 is sealed at both ends along its length. Figure 4 and 5 In the embodiment, the convex portion is located on the outer side of the integrally formed cover 4.

[0071] Among them, the front end of the convex part of the integrally formed cover 4 and the cylinder cover shell of the integrally formed cover 4 are connected through an inclined drainage surface, and the inclined drainage surface is set as an inclined folded surface or an inclined curved surface. It should be noted that when the inclined drainage surface is an inclined folded surface, the folding angle of the inclined folded surface is an obtuse angle; when the inclined drainage surface is an inclined curved surface, the inclined curved surface is an outward convex curved surface.

[0072] The tail end of the convex portion of the integrally formed cover 4 and the cylinder cover shell of the integrally formed cover 4 are connected in a curved surface or an inclined surface.

[0073] like Figure 5 As shown, the integral forming cover 4 is installed on the cylinder assembly α Phase position. Among them, the cylinder assembly includes a cylinder shaft and a cylinder, the cylinder is installed on the cylinder shaft, and the cylinder shaft rotates. Therefore, the cylinder and the integrally formed cover 4 with the cylinder cover shell will rotate with the rotation of the cylinder shaft. At this time, the cylinder rotates counterclockwise.

[0074] Specifically, the integrally formed cover 4 is installed on the cylinder shaft through an integrally formed cylinder cover shell. In the specific installation structure of the integrally formed cover 4, the mounting screw assembly II5 passes through the cylinder cover shell of the integrally formed cover 4 and is installed on the cylinder seat. The mounting screw assembly II5 includes a gasket and a bolt, that is, the bolt passes through the cylinder cover shell of the integrally formed cover 4 and is screwed into the threaded hole of the cylinder seat, thereby fixing the integrally formed cover 4.

[0075] After the integral molded cover 4 is installed, the position distribution between the various structures is as follows:

[0076] The rear part of the needle plate seat of the cylinder is located in the counterclockwise direction of the integral forming cover 4. There is a phase difference space between the convex part of the integral forming cover 4 and it. This phase difference space forms an airflow cavity, which cooperates with the opening of the nipper.

[0077] The minimum radial distance between the convex portion of the integral forming cover 4 and the axis of the cylinder is greater than the maximum radial distance between the front portion of the integral forming cover 4 and the axis of the cylinder;

[0078] The minimum radial distance between the convex portion of the integral forming cover 4 and the axis of the cylinder is greater than the maximum radial distance between the tail portion of the integral forming cover 4 and the axis of the cylinder;

[0079] Along the rotation direction of the cylinder, the front end of the convex portion of the integrally formed cover 4 is the outermost key point of the integrally formed cover 4;

[0080] The angle between the line connecting the outermost key point of the integral forming cover 4 to the axis of the cylinder and the vertical line passing through the axis of the cylinder when the upper and lower nippers of the cotton combing machine are opened is α, where 0°≤α≤70°. In this embodiment, α is 48.8°.

[0081] Along the axial direction of the cylinder, both end faces of the integrally formed cover 4 are closed;

[0082] Along the rotating direction of the cylinder, the straight-line distance between the convex width of the integral forming cover 4 and the two ends of the cylinder circumference is A, where 0mm<A≤40mm. In this embodiment, A is 15mm.

[0083] like Figure 6 As shown, after the cylinder assembly with the integral forming cover 4 is installed on the combing machine, the position distribution between the various structures is as follows:

[0084] The rear portion of the cylinder needle row seat is located below the nipper opening. During the first half of the cylinder assembly's rotation and the gradual opening of the nipper, the airflow chamber will be located to the lower right, lower, and lower left of the nipper opening. During this process, the airflow in the airflow chamber flows along the leading edge of the convex portion of the integral forming cover 4 toward the nipper opening, thereby causing the fiber strands at the nipper opening to rise.

[0085] The radial distance between the outermost point of the integrally formed cover 4 and the cylinder axis is less than the vertical distance between the bottom surface of the lower nipper and the cylinder axis, ensuring that the integrally formed cover 4 does not interfere with the movement of the lower nipper bottom. In this embodiment, the radial distance between the outermost point of the integrally formed cover 4 and the cylinder axis is 61.5 mm. It should be noted that in this embodiment, the outermost point of the integrally formed cover 4 and the outermost key point of the integrally formed cover 4 are not necessarily located at the same position. The outermost key point of the integrally formed cover 4 is the front end of the convex portion of the integrally formed cover 4. The outermost point of the integrally formed cover 4 can be the front end, middle end, or rear end of the convex portion of the integrally formed cover 4.

[0086] like Figure 6 As shown, a driving method for quickly raising the fiber beard bundle when the nipper of a cotton combing machine is opened is provided.

[0087] The driving method includes the following steps:

[0088] S1. The cylinder assembly is operating, and the integral forming hood 4 rotates counterclockwise with the cylinder assembly, thereby forming an airflow in the airflow chamber that drives the fiber clump upward. The integral forming hood 4 is sealed at both ends to reduce airflow disturbance at the cylinder end.

[0089] S2. The nipper plate is opening. When the nipper plate is just opened, the integral forming cover 4 rotates to the cylinder assembly. α In the phase position, α is 48.8°. Then, as the nipper opening gradually becomes larger, the fiber beard cluster rises and the airflow actively pushes the fiber beard cluster at the nipper opening to rise quickly. It should be noted that the phase α The value of is determined by the opening speed of the nipper opening and the rotation speed of the cylinder assembly.

[0090] The working process of Example 2 will be further described below:

[0091] Install the integral forming cover 4 and the cylinder assembly on the combing machine respectively;

[0092] When the cylinder shaft rotates and drives the cylinder to comb the fiber bundle, the upper and lower nippers of the combing machine begin to open;

[0093] When the clamp is just opened, the integral forming cover 4 rotates to the cylinder assembly. α In the phase position, α is 48.8°, at which point the integrally formed cover 4 is below the nipper opening;

[0094] Afterwards, the nipper opening continues the opening process;

[0095] The convex part of the integral forming cover 4 pushes the airflow forward as the cylinder shaft rotates, and then actively pushes up the fiber layer and the beard clumps to rise quickly. As the cylinder assembly continues to rotate, the convex part of the integral forming cover 4 rotates and passes just when the fiber beard clumps are about to overlap, thus completing its function;

[0096] At this time, the airflow below the fiber beard bundle is quickly drawn downward by the negative pressure of the inhalation duct to complete the splicing.

[0097] The above description is merely a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Any person skilled in the art can utilize the methods and technical contents disclosed above to make many possible variations and modifications to the technical solutions of the present invention without departing from the scope of the technical solutions of the present invention, or modify them into equivalent embodiments with equivalent variations.
