The application belongs to the technical field of spinning equipment, and proposes a hollow spindle thread machine and a thread yarn correction method. The hollow spindle thread machine comprises a yarn forming mechanism, a first hollow spindle and a second hollow spindle. The finished thread yarn is twisted by the first hollow spindle, and then a woven fabric made of the twisted finished thread yarn is obtained, and whether the woven fabric is inclined is judged. The twisted finished thread yarn is twisted in the opposite direction by the second hollow spindle.

Description

Technical Field

[0001] This invention relates to the field of spinning equipment technology, and in particular to a hollow spindle chenille machine and a chenille yarn correction method. Background Technology

[0002] A chenille spinning machine is a new type of spinning equipment used to produce chenille yarn. Chenille yarn is fluffy, full, soft to the touch, and brightly colored. It is currently widely used in home decor fabrics, automotive trim fabrics, and apparel fabrics.

[0003] After chenille yarn is produced, it is woven into fabric. However, due to the instability of the chenille yarn pattern, the fabric may exhibit a skewed appearance, which affects the aesthetics of the fabric. Understandably, if the chenille yarn pattern is stable, the woven fabric will be square in shape, which is convenient for subsequent fabric processing. If the chenille yarn pattern is unstable, the woven fabric will tend to be a parallelogram in shape. This phenomenon is usually called skewed appearance, which is not conducive to subsequent fabric processing.

[0004] To address the issue of skewed yarn, hollow spindles are often used to apply twisting force to the finished chenille yarn during the production process on chenille spinning machines. This increases the twist of the chenille yarn and thus improves its stability. However, over-twisting may occur during the twisting process, resulting in skewed yarn remaining in the woven fabric.

[0005] Therefore, the above problems urgently need to be solved. Summary of the Invention

[0006] The purpose of this invention is to provide a hollow spindle chenille machine and a chenille yarn correction method to improve the quality of chenille yarn.

[0007] To achieve this objective, the present invention adopts the following technical solution:

[0008] A hollow spindle chenille machine includes a yarn forming mechanism and a first hollow spindle. The yarn forming mechanism is configured to output finished chenille yarn. The first hollow spindle is disposed downstream of the yarn forming mechanism along the conveying direction of the finished chenille yarn. The hollow spindle chenille machine also includes a second hollow spindle disposed downstream of the first hollow spindle.

[0009] The first hollow ingot and the second hollow ingot rotate in opposite directions, the first hollow ingot and the second hollow ingot rotate at different speeds, and at least one of the first hollow ingot and the second hollow ingot has an adjustable speed.

[0010] Preferably, the rotational speed of the second hollow ingot is lower than that of the first hollow ingot.

[0011] Preferably, the output end of the first hollow ingot is positioned opposite to the input end of the second hollow ingot.

[0012] Preferably, the hollow spindle chenille machine further includes two twisters, which are respectively disposed at the bottom of the first hollow spindle and the second hollow spindle.

[0013] Preferably, the hollow spindle chenille machine further includes two yarn-fixing tubes for winding the fixed yarn. The two yarn-fixing tubes are respectively disposed on the top of the first hollow spindle and the second hollow spindle, and the yarn-fixing tubes are configured to wind the fixed yarn around the outer peripheral wall of the finished chenille yarn.

[0014] Preferably, the two fixed yarns are different colors.

[0015] Preferably, the hollow ingot chenille machine further includes an output roller, the input end of which is arranged opposite to the output end of the second hollow ingot.

[0016] A method for correcting chenille yarn includes the following steps:

[0017] Finished chenille yarn is produced by a yarn forming mechanism and then twisted by one of the first hollow spindles or the second hollow spindle.

[0018] Obtain a fabric made from the twisted finished chenille yarn, and determine whether the fabric is tilted;

[0019] The twisted finished chenille yarn is then reverse-twisted through another part of both the first hollow spindle and the second hollow spindle;

[0020] Obtain a fabric made from the reverse twisted yarn, and determine whether the fabric is still tilted. If it is still tilted, adjust the rotation speed of the first hollow spindle or the second hollow spindle.

[0021] Preferably, if the tilt still exists, adjusting the rotational speed of the first hollow ingot or the second hollow ingot includes:

[0022] If the two pieces of fabric are tilted in the same direction, the rotational speed of the lower of the first and second hollow spindles is increased; conversely, the rotational speed of the lower of the first and second hollow spindles is decreased.

[0023] Preferably, both the first hollow spindle and the second hollow spindle are provided with a yarn-fixing tube at their top, and the yarn-fixing tubes are wrapped with yarn of different colors.

[0024] The chenille yarn correction method also includes:

[0025] The different colored yarns are sequentially wound around the outer periphery of the finished chenille yarn.

[0026] The beneficial effects of this invention are:

[0027] The hollow-spindle chenille machine and chenille yarn correction method proposed in this invention employs a yarn forming mechanism to output finished chenille yarn, which is then twisted by a first hollow spindle. Fabric made from the twisted finished chenille yarn is then obtained, and its tilt is assessed. The twisted finished chenille yarn is then reverse-twisted by a second hollow spindle with the opposite rotation direction to the first hollow spindle. Fabric made from the reverse-twisted yarn is then obtained, and its tilt is assessed again. If tilt persists, the rotation speed of the second hollow spindle is adjusted. Compared to existing technologies that increase the twist of chenille yarn using a single hollow spindle, the first and second hollow spindles with opposite rotation directions used in this invention can adjust their rotation speeds according to the tilt direction of the fabric, thereby improving the fabric shape and even preventing skewing, thus improving the quality of the chenille yarn.

[0035] Before explaining any implementation of this application in detail, it should be understood that this application is not limited to its application to the structural details and component arrangements set forth in the following description or shown in the above drawings.

[0036] In this application, the terms "comprising," "including," "having," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0037] In this application, the term "and / or" describes a relationship between related objects, indicating that three relationships can exist. For example, a centrifugal vortex magnetic pump and / or a centrifugal vortex magnetic pump can represent: the existence of only one centrifugal vortex magnetic pump, the simultaneous existence of one centrifugal vortex magnetic pump and a centrifugal vortex magnetic pump, or the existence of only one centrifugal vortex magnetic pump. Additionally, the character " / " in this application generally indicates that the preceding and following related objects have an "and / or" relationship.

[0038] In this application, the terms "connection," "combination," "coupling," and "installation" can refer to direct connection, combination, coupling, or installation, or indirect connection, combination, coupling, or installation. For example, a direct connection refers to two parts or components being connected together without the need for an intermediary, while an indirect connection refers to two parts or components each being connected to at least one intermediary, with the connection achieved through the intermediary. Furthermore, "connection" and "coupling" are not limited to physical or mechanical connections or couplings, but can also include electrical connections or couplings.

[0039] In this application, those skilled in the art will understand that relative terms (e.g., “about,” “approximately,” “basically,” etc.) used in conjunction with quantities or conditions are to include the values ​​and have the meaning indicated by the context. For example, such relative terms include at least the degree of error associated with the measurement of a particular value, tolerances associated with the particular value due to manufacturing, assembly, use, etc. Such terms should also be considered as disclosing a range defined by the absolute values ​​of the two endpoints. Relative terms may refer to a certain percentage (e.g., 1%, 5%, 10% or more) of the indicated value. Numerical values ​​not using relative terms should also be disclosed as specific values ​​with tolerances. Furthermore, “basically” when expressing relative angular relationships (e.g., substantially parallel, substantially perpendicular) may refer to a certain degree (e.g., 1 degree, 5 degrees, 10 degrees or more) added to or subtracted from the indicated angle.

[0040] In this application, those skilled in the art will understand that the function performed by a component can be performed by one component, multiple components, one part, or multiple parts. Similarly, the function performed by a part can also be performed by one part, one component, or a combination of multiple parts.

[0041] In this application, the directional terms "upper," "lower," "left," "right," "front," and "rear" are used to describe the orientation and positional relationships shown in the accompanying drawings and should not be construed as limiting the embodiments of this application. Furthermore, in the context, it should be understood that when an element is mentioned as being connected "upper" or "lower" to another element, it can be directly connected to the other element "upper" or "lower," or indirectly connected through an intermediate element. It should also be understood that directional terms such as upper side, lower side, left side, right side, front side, and rear side not only represent positive orientation but can also be understood as lateral orientation. For example, "below" can include directly below, lower left, lower right, lower front, and lower rear.

[0042] Please see Figures 1 to 3 To address the issue of unstable patterns in existing chenille yarn designs, this embodiment proposes a hollow spindle chenille machine, which includes a yarn forming mechanism 1 and a first hollow spindle 2. The yarn forming mechanism 1 is configured to output finished chenille yarn. The first hollow spindle 2 is located downstream of the yarn forming mechanism 1 along the conveying direction of the finished chenille yarn. The hollow spindle chenille machine also includes a second hollow spindle 3, which is located downstream of the first hollow spindle 2. The first hollow spindle 2 and the second hollow spindle 3 have opposite rotational directions, and the rotational speed of at least one of the first hollow spindle 2 and the second hollow spindle 3 is adjustable.

[0043] Understandably, the yarn forming mechanism 1 outputs finished chenille yarn, which is then twisted by one of the first hollow spindle 2 and the second hollow spindle 3. Fabric made from the twisted finished chenille yarn is then obtained, and it is determined whether the fabric is tilted. The twisted finished chenille yarn is then reverse-twisted by the other of the first hollow spindle 2 and the second hollow spindle 3. Fabric made from the reverse-twisted yarn is then obtained, and it is determined whether the fabric is still tilted. If it is still tilted, the rotation speed of the first hollow spindle 2 or the second hollow spindle 3 is adjusted. Compared to the prior art that increases the twist of chenille yarn through a single hollow spindle, the first hollow spindle 2 and the second hollow spindle 3 with opposite rotation directions used in this invention can adjust the rotation speed of the first hollow spindle 2 or the second hollow spindle 3 according to the tilt direction of the fabric, thereby improving the shape of the fabric and even avoiding the formation of skewed pieces, thus improving the quality of the chenille yarn.

[0044] It should be noted that when the yarn is first twisted using the first hollow spindle 2 or the second hollow spindle 3, the rotation speed of the first hollow spindle 2 and the second hollow spindle 3 should be ensured so that the finished chenille yarn can be twisted to a certain twist.

[0045] It should also be noted that hollow spindles are commonly used components in textile manufacturing processes. Therefore, the specific structures and uses of the first hollow spindle 2 and the second hollow spindle 3 are well known to those skilled in the art, and will not be described in detail here.

[0046] Furthermore, the rotational speed of the second hollow spindle 3 is lower than that of the first hollow spindle 2. It is understandable that after the finished chenille yarn is twisted by the first hollow spindle 2, if the finished chenille yarn is over-twisted, the twisted finished chenille yarn is then reverse-twisted to reduce the twist of the finished chenille yarn, thereby improving the shape of the fabric processed from the finished chenille yarn.

[0047] It should be noted that the rotational speeds of the first hollow ingot 2 and the second hollow ingot 3 are determined according to the actual working conditions, and no specific restrictions are imposed here.

[0048] Specifically, the output end of the first hollow spindle 2 is positioned opposite the input end of the second hollow spindle 3. This arrangement prevents the finished chenille yarn from shifting due to differences in rotation speed and direction when the first hollow spindle 2 and the second hollow spindle 3 are joined, thereby further improving the quality of the chenille yarn during twisting.

[0049] The hollow spindle chenille machine also includes two twisters 5, which are respectively located at the bottom of the first hollow spindle 2 and the second hollow spindle 3. This arrangement can further increase the strength and stability of the finished chenille yarn during twisting.

[0050] The hollow spindle chenille machine also includes two yarn-fixing tubes 4 for winding the fixed yarn. The two yarn-fixing tubes 4 are respectively located on the top of the first hollow spindle 2 and the second hollow spindle 3, and are configured to wind the fixed yarn around the outer periphery of the finished chenille yarn. It can be understood that before the finished chenille yarn is twisted by the first hollow spindle 2 or the second hollow spindle 3, the fixed yarn wound around the outer periphery of the yarn-fixing tubes 4 is first wound onto the outside of the chenille yarn. Then, under the action of the hollow spindles and the twister 5, a twisting force can be applied between the fixed yarn and the chenille yarn to increase the twist between them, thereby reducing the shedding rate of the chenille yarn and improving its quality.

[0051] It should be noted that the yarn fixing tube 4 and the twister 5 are commonly used components in the textile process, and their specific structures and uses are well known to those skilled in the art, so they will not be described in detail here.

[0052] In particular, the two fixed yarns are different colors. This arrangement allows for the selection of different colored fixed yarns to be wound onto the fixed yarn tube 4 according to different needs, in order to obtain mixed-color finished chenille yarn, thereby increasing the variety of fabric patterns.

[0053] In this embodiment, the hollow spindle chenille machine also includes an output roller 6, the input end of which is positioned opposite to the output end of the second hollow spindle 3. It is understood that when the finished chenille yarn is transported between the output roller 6 and the second hollow spindle 3, the core yarn 100 and the yarn in the finished chenille yarn may shift under the action of two different torques. Therefore, in this embodiment, the input end of the output roller 6 is positioned opposite to the output end of the second hollow spindle 3.

[0054] It should be noted that the output roller 6 is a commonly used component in textile processes, and its specific structure and use are well known to those skilled in the art, so they will not be described in detail here.

[0055] To facilitate the winding of the twisted finished chenille yarn, the hollow spindle chenille machine also includes a grooved drum winding mechanism 7. The grooved drum winding mechanism 7 is located downstream of the output roller 6 and is configured to wind the finished chenille yarn. Specifically, the grooved drum winding mechanism 7 includes a servo motor and a rotating shaft. The rotating shaft is located at the rotating end of the servo motor. During winding, the grooved drum is fitted onto the rotating shaft, and then the servo motor drives the rotating shaft to rotate, thereby completing the winding of the finished chenille yarn.

[0056] In this embodiment, the yarn forming mechanism 1 includes a core yarn conveying unit 11, a decorative yarn conveying unit 12, and a yarn forming unit 13. The core yarn conveying unit 11 is configured to convey the core yarn 100 to the yarn forming unit 13, the decorative yarn conveying unit 12 is configured to convey the decorative yarn 200 to the yarn forming unit 13, and the yarn forming unit 13 is configured to form the core yarn 100 and the decorative yarn 200 into finished chenille yarn. In practical applications, the core yarn conveying unit 11, the decorative yarn conveying unit 12, and the yarn forming unit 13 are all mounted on the support 8.

[0057] Specifically, the core wire conveying unit 11 includes a wire frame disposed on the support 8, and the core wire 100 is wound on the wire frame. The decorative yarn conveying unit 12 includes a yarn frame disposed on the support 8, and the decorative yarn 200 is wound on the yarn frame. The yarn forming unit 13 includes a forming frame, spacers 131, a roller assembly, a rotary head 132, a cutter holder, and a blade. The forming frame is mounted on the support 8. Two spacers 131 are mounted on the forming frame and are spaced apart. The rotary head 132 is positioned above the spacers 131 and is configured to wind the decorative yarn 200 around the two spacers 131. The roller assembly is mounted on the forming frame and is configured to drive the decorative yarn 200 and the core yarn 100 wound around the two spacers 131 in a preset direction, which refers to the direction in which the finished chenille yarn is output. The cutter holder is mounted vertically on the forming frame. The blade is mounted on the cutter holder and is located directly below the two spacers 131. The blade is capable of cutting the decorative yarn 200 wound around the two spacers 131. It should be noted that the number of core wire conveying units 11 and decorative yarn conveying units 12 depends on the actual working conditions, and will not be elaborated here.

[0058] Exemplarily, during the spinning process, the decorative yarn 200 is unwound from the yarn frame and then wound onto the spacer plate 131 under the action of the rotary head 132 to form a loop. The loop slides downward under the action of the roller assembly and is then cut into short fibers by the blades. The core yarn 100 is then divided into a first yarn and a second yarn. Under the action of the roller assembly, the first and second yarns are unwound from their respective yarn frames and fed together into the spacer plate 131. Then, under the action of the roller assembly and the two spacer plates 131, the first and second yarns are positioned on opposite sides of the short fibers. With the high-speed rotation of the hollow spindle, the core yarn 100 is rapidly twisted, thereby firmly bonding the core yarn 100 with the short fibers to form a full-bodied chenille yarn.

[0059] Based on the above, this embodiment also proposes a chenille yarn correction method, which includes the following steps:

[0060] Step 1: The finished chenille yarn is output by the yarn forming mechanism 1, and then twisted by one of the first hollow spindle 2 and the second hollow spindle 3. It can be understood that when twisting the finished chenille yarn, it is first twisted by the first hollow spindle 2 or the second hollow spindle 3, so that the finished chenille yarn has a certain twist. If the twist is too large, it will cause the twist of the finished chenille yarn itself to be too large, which will easily lead to the skewing phenomenon of the woven fabric after spinning.

[0061] Step 2: Obtain the fabric made from the twisted finished chenille yarn and determine if the fabric is tilted; that is, determine whether the shape of the fabric is square or tilted parallelogram. If it is square, there is no need to reverse twist the finished chenille yarn; if it is parallelogram or close to parallelogram, then the finished chenille yarn needs to be reverse twisted.

[0062] Step 3: The twisted finished chenille yarn is reverse-twisted by one of the first hollow spindles 2 and the second hollow spindle 3. It is understood that if the twist of the finished chenille yarn is too high, it needs to be reverse-twisted to reduce its twist. For example, the first hollow spindle 2 twists the chenille yarn, and the second hollow spindle 3 reverse-twistrudes the finished chenille yarn. The first hollow spindle 2 and the second hollow spindle 3 rotate in opposite directions, and the rotational speed of the first hollow spindle 2 is higher than that of the second hollow spindle 3.

[0063] Step 4: Obtain the fabric made from the reverse-twisted yarn and determine if the fabric still has a tilt. If it does, adjust the rotation speed of the first hollow spindle 2 or the second hollow spindle 3. It can be understood that after reverse twisting, the finished chenille yarn is woven into fabric again, and then the tilt is determined to improve the shape of the fabric, thereby improving the twisting quality of the finished chenille yarn.

[0064] Furthermore, if the tilt persists, adjusting the rotational speed of the first hollow spindle 2 or the second hollow spindle 3 involves: if the two pieces of fabric are tilted in the same direction, increasing the lower rotational speed of the first hollow spindle 2 or the second hollow spindle 3; conversely, decreasing the lower rotational speed of the first hollow spindle 2 or the second hollow spindle 3. It is understood that by adjusting the rotational speed of the first hollow spindle 2 or the second hollow spindle 3 used for reverse twisting, the twist of the finished chenille yarn can be gradually adjusted, thereby gradually adjusting the shape of the fabric.

[0065] In addition, when the colors of the fixed yarns wound on the two fixed yarn tubes 4 are different, the fixed yarns of different colors can be wound sequentially around the outer periphery of the finished chenille yarn as needed, so as to obtain the mixed-color finished chenille yarn, thereby increasing the variety of fabric patterns.

[0066] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art will be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
