Description

Technical Field

[0001] The utility model relates to the technical field of textile machinery, in particular to a spacer installation mechanism and a chenille machine. Background Art

[0002] Chenille spinning machine is a new type of spinning equipment for producing chenille yarn. Chenille yarn has fluffy and full nap, soft touch and bright colors. It is currently widely used in home decoration fabrics, car decoration fabrics and clothing fabrics.

[0003] When installing the gauge installation mechanism of a traditional chenille machine, it is necessary to ensure that the cutting yarn working position of the gauge neck coincides with the axis of the output roller in the chenille yarn forming mechanism, and the center line of the gauge coincides with the center of the rotary disk to ensure the quality of the yarn. Specifically, the commonly used gauge seat on the market has a short contact area with the gauge at the tail end, and the front end is a cantilever; if it is not installed vertically, the roller may be pressed on and the gauge may be bent; plus there is always a downward force acting on the gauge when making the yarn, which will cause displacement and deformation, thus affecting the quality of the yarn.

[0004] At present, this process mostly relies on the experience of the operator to adjust the position of the gauge. Therefore, the operator needs to be trained to a certain extent, which leads to increased labor costs. In addition, when the position of the gauge is adjusted manually, not only the adjustment time is too long, but it is also easy to cause improper installation, resulting in unstable yarn quality.

[0035] Before any embodiments of the application are explained in detail, it is to be understood that the application is not limited in its application to the details of construction and the arrangement of components set forth in the following description or illustrated in the above drawings.

[0036] In this application, the terms "comprises", "includes", "has" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device that includes a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of more restrictions, an element defined by the sentence "comprises a ..." does not exclude the presence of other identical elements in the process, method, article or device that includes the element.

[0037] In the present application, the term "and / or" is a description of the association relationship of associated objects, indicating that three relationships may exist. For example, a centrifugal vortex magnetic pump and / or a centrifugal vortex magnetic pump can represent: the existence of a centrifugal vortex magnetic pump alone, the existence of a centrifugal vortex magnetic pump and a centrifugal vortex magnetic pump at the same time, and the existence of a centrifugal vortex magnetic pump alone. In addition, the character " / " in the present application generally indicates that the objects associated before and after are in an "and / or" relationship.

[0038] In the present application, the terms "connect", "combine", "couple", and "install" may refer to direct connection, combination, coupling, or installation, or indirect connection, combination, coupling, or installation. For example, direct connection refers to two parts or components being connected together without the need for an intermediate piece, and indirect connection refers to two parts or components being connected to at least one intermediate piece respectively, and the two parts or components being connected via the intermediate piece. In addition, "connect" and "couple" are not limited to physical or mechanical connections or couplings, and may include electrical connections or couplings.

[0039] In the present application, it will be understood by those of ordinary skill in the art that relative terms (e.g., "about," "approximately," "substantially," etc.) used in conjunction with quantities or conditions include the values ​​and have the meaning indicated by the context. For example, the relative terms include at least the degree of error associated with the measurement of a specific value, the tolerances caused by manufacturing, assembly, and use associated with a specific value, and the like. Such terms should also be considered to disclose a range defined by the absolute values ​​of the two endpoints. Relative terms may refer to plus or minus a certain percentage (e.g., 1%, 5%, 10% or more) of the indicated value. Numerical values ​​that do not use relative terms should also be disclosed as specific values ​​with tolerances. In addition, "substantially" may refer to plus or minus a certain degree (e.g., 1 degree, 5 degrees, 10 degrees or more) on the basis of the indicated angle when expressing a relative angular position relationship (e.g., substantially parallel, substantially perpendicular).

[0040] In this application, it will be understood by those skilled in the art 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 the present application, the terms "upper", "lower", "left", "right", "front", "back" and other directional words are described based on the orientation and positional relationship shown in the accompanying drawings, and should not be understood as limiting the embodiments of the present application. In addition, in the context, it is also necessary to understand that when it is mentioned that an element is connected to another element "upper" or "lower", it can not only be directly connected to another element "upper" or "lower", but also indirectly connected to another element "upper" or "lower" through an intermediate element. It should also be understood that directional words such as upper side, lower side, left side, right side, front side, back side, etc. not only represent the positive orientation, but can also be understood as the lateral orientation. For example, the bottom can include directly below, lower left, lower right, lower front, and lower back, etc.

[0042] When installing the gauge installation mechanism of the traditional chenille machine, it is necessary to ensure that the cutting yarn working position of the gauge neck coincides with the axis of the output roller in the chenille yarn forming mechanism, and the center line of the gauge coincides with the center of the rotary disk to ensure the quality of the yarn. For example, the commonly used gauge seat on the market has a short contact area with the gauge at the tail end, and the front end is a cantilever; if it is not installed vertically, the roller may be pressed on and the gauge may be bent; plus there is always a downward force on the gauge when making yarn, which will cause displacement and deformation, thus affecting the quality of the yarn. At present, this process mostly relies on the experience of the operator to adjust the position of the gauge. Therefore, the operator needs to be trained to a certain extent, which leads to an increase in labor costs. In addition, when the position of the gauge is adjusted manually, not only the adjustment time is too long, but it is also easy to cause the installation to be inadequate, resulting in unstable yarn quality.

[0043] Based on the above, please refer to Figures 1 to 6 In this embodiment, a chenille machine is provided, including a gauge 3, an output roller 200, a rotary disk 300 and a gauge installation mechanism 100. The gauge installation mechanism 100 is used to cut the velvet yarn. To ensure the yarn making efficiency, the working position of the gauge 3 for cutting the decorative yarn coincides with the axis of the output roller 200, and the center line of the gauge 3 coincides with the center of the rotary disk 300. It can be understood that when installing the gauge 3, the installation efficiency and installation accuracy can be improved under the action of the gauge installation mechanism 100.

[0044] Furthermore, the present embodiment also provides a spacer installation mechanism 100 for installing a spacer 3, which includes a base 1 and a spacer seat 2; the two ends of the spacer seat 2 are respectively connected to the base 1 and the spacer 3; the side wall of the spacer 3 along the Z direction is in contact with the corresponding side wall of the spacer seat 2; the end of the spacer seat 2 adjacent to the spacer 3 is provided with a first positioning portion 21 and a second positioning portion 22, and the spacer 3 is provided with a third positioning portion 31 and a fourth positioning portion 32, the first positioning portion 21 is adapted to the third positioning portion 31 to locate the installation position of the spacer 3 along the X direction, and the second positioning portion 22 is adapted to the fourth positioning portion 32 to locate the installation position of the spacer 3 along the Y direction; the X direction, the Y direction and the Z direction are arranged perpendicular to each other.

[0045] It can be understood that when installing the spacer 3, the side wall of the spacer 3 along the Z direction is first fitted with the corresponding side wall of the spacer seat 2, and then the positioning between the spacer 3 and the spacer seat 2 can be completed with the cooperation between the first positioning portion 21 and the third positioning portion 31, and the cooperation between the second positioning portion 22 and the third positioning portion 31, thereby facilitating the improvement of the installation accuracy and efficiency between the spacer 3 and the spacer seat 2.

[0046] Specifically, the first positioning portion 21 is a groove, the length direction of the groove is arranged along the Y direction, and the notch of the groove is arranged toward the spacer 3; the third positioning portion 31 is the side wall of the spacer 3 along the Z direction. And the side wall of the spacer 3 along the Z direction can fit with the groove bottom of the groove. It can be understood that before installing the spacer 3, the side wall of the spacer 3 along the Z direction is fitted with the groove wall of the groove, so as to ensure that when the spacer 3 is installed, the spacer 3 will not be offset along the Y direction or the Z direction, so as to ensure the installation efficiency and installation quality of the spacer 3. In some other feasible embodiments, the second positioning portion 22 can be a protrusion adapted to the above-mentioned groove, which is not specifically limited here.

[0047] Further, the third positioning portion 31 and the fourth positioning portion 32 are both positioning holes, the axes of the two positioning holes are arranged along the Z direction, and the two positioning holes can be positioned with each other by a positioning pin. It can be understood that when the protrusion slides in the groove, when the third positioning portion 31 and the fourth positioning portion 32 are arranged relative to each other, that is, when the two positioning holes are arranged relative to each other, the positioning pins are inserted into the two positioning holes at the same time to complete the positioning of the spacer 3, and then the spacer 3 is fixed to the spacer seat 2 by the fixing bolt to complete the installation of the spacer 3.

[0048] In some other feasible embodiments, the third positioning portion 31 and the fourth positioning portion can also be positioning blocks. When the spacer 3 is moved to the preset installation position in the Y direction, the two positioning blocks can overlap with each other to cause mutual limitation, thereby completing the positioning of the installation position of the spacer 3 in the Y direction.

[0049] Preferably, the third positioning portion 31 is arranged at the bottom of the groove. Such arrangement facilitates limiting the movement stroke of the protrusion in the groove to improve the positioning accuracy of the spacer 3. In order to further determine the positioning accuracy and installation efficiency of the spacer 3, it is also necessary to ensure the installation accuracy and installation efficiency between the spacer 2 and the base 1 in this embodiment. For this purpose, the spacer 2 is provided with a fifth positioning portion 23, and the base 1 is provided with a sixth positioning portion 11, and the fifth positioning portion 23 is adapted to the sixth positioning portion 11. It can be understood that the fifth positioning portion 23 is arranged at one end of the spacer 2, and the first positioning portion 21 and the second positioning portion 22 are both arranged at the other end of the spacer 2. And under the action of the fifth positioning portion 23 and the sixth positioning portion 11, the positioning accuracy and installation efficiency of the spacer 2 can be improved.

[0050] Specifically, the fifth positioning portion 23 is a card block, and the card block is convexly arranged on the spacing seat 2, and the sixth positioning portion 11 is a card slot, the length direction of the card slot is arranged along the Y direction, the side wall of the card block along the X direction is in contact with the bottom wall of the card slot, and the side wall of the card block along the Z direction is in contact with the side wall of the card slot. It can be understood that when the spacing seat 2 is installed, the card block is slidably arranged in the card slot, so that the side wall of the card block along the X direction is in contact with the bottom wall of the card slot, and the side wall of the card block along the Z direction is in contact with the side wall of the card slot. Thereby ensuring that when the spacing seat 2 is installed, the spacing seat 2 will not be offset in the X direction or the Z direction, so that the installation efficiency and installation quality of the spacing piece 3 can be guaranteed.

[0051] In some other feasible embodiments, the fifth positioning portion 23 is a card slot, and the sixth positioning portion 11 is a card block adapted thereto, which is not specifically limited here.

[0052] Further, the end of the card slot along the Y direction is provided with a step surface 12, and the end of the card block along the Y direction is provided with a flange 24, and the flange 24 can overlap the step surface 12. It can be understood that when the card block slides in the card slot, when the step surface 12 and the flange 24 are mutually limited, the positioning of the spacer 2 can be completed, and then the spacer 2 is fixed to the base 1 by fixing bolts to complete the installation of the spacer 2.

[0053] In some other feasible embodiments, the step surface 12 and the flange 24 can also be replaced by positioning blocks. When the spacer 2 is moved to the preset installation position in the Y direction, the two positioning blocks can overlap each other to cause mutual limitation, thereby completing the positioning of the installation position of the spacer 2 in the Y direction.

[0054] In this embodiment, the gauge piece 3 includes a profiling surface, and the shape of the profiling surface is similar to the shape of the roller piece 200 that the gauge piece 3 is attached to. This arrangement facilitates that after the gauge piece 3 is installed, the gauge piece 3 can be completely attached to the roller piece 200 to further improve the yarn quality.

[0055] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention. It is not necessary and impossible to list all implementation methods here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall be included in the scope of protection of the claims of the present invention.
