DETAILED DESCRIPTION

[0056] To more clearly illustrate the embodiments of the present invention and the technical solutions in the prior art, the following describes specific embodiments of the present invention with reference to the accompanying drawings. Obviously, the drawings described below are merely examples of the present invention. A person skilled in the art can, without inventive effort, derive other drawings and other embodiments from these drawings. Furthermore, design orientations only represent relative positional relationships between components, not absolute positional relationships.

[0057] The present invention provides a yarn feeding device. Figures 1-11 It mainly includes a yarn feeder 1, a base plate 2 located on the flat knitting machine, a yarn feeding structure 3 and a yarn guide structure 4. The bottoms of multiple yarn feeders 1 are fixed in parallel on the base plate 2, and the upper parts of multiple yarn feeders 1 are fixed to the yarn feeding structure 3; the yarn guide structure 4 is arranged below the base plate 2, and the yarn feeding structure 3 is equipped with a yarn feeding porcelain eye 91, and the yarn 9 is introduced into the yarn feeder 1 or the yarn guide structure 4 through the yarn feeding porcelain eye 91; the yarn guide structure 4 is equipped with a yarn guide porcelain eye 92 and a yarn guide wheel 8, and the yarn 9 is led out through the yarn guide porcelain eye 92 or the yarn guide wheel 8.

[0058] In this application, the running path of the yarn 9 can be selected according to actual needs to select whether to pass through the yarn feeder 1 or the yarn guide wheel 8, and the specific running mode includes:

[0059] First, the yarn 9 can be introduced into the yarn feeder 1 through the yarn inlet eye 91 and led out through the yarn guide wheel 8; at this time, the yarn feeding effect of the active yarn feeder can be achieved, and at the same time, it is convenient for measurement.

[0060] Secondly, the yarn 9 can be introduced into the yarn feeder 1 through the yarn inlet eyelet 91 and led out through the yarn guide eyelet 92; at this time, the yarn feeding effect of the active yarn feeder can be achieved.

[0061] Thirdly, the yarn 9 can be introduced through the yarn feed eyelet 91 and directly introduced into the yarn guide wheel 8 or the yarn guide eyelet 92 without passing through the yarn feeder 1; at this time, the yarn feeding effect of the passive yarn feeder can be achieved.

[0062] It can be understood that not passing through the yarn feeder 1 means not being affected by the active drive of the yarn feeder 1, rather than not guiding the yarn to run with the help of the non-driven related components of the yarn feeder, such as yarn guide hooks, yarn coils, tension devices and yarn guides.

[0063] In this application, a base plate 2 can be set at one end of the flat knitting machine, and multiple yarn feeders 1 can be mounted on the base plate 2 and combined with the yarn feeding structure 3 and the yarn guide structure 4 to form the yarn feeding device of this application. The yarn feeder 1 is stably installed on the base plate 2, and the multiple yarn feeders 1 are distributed in parallel, such as Figure 1 As shown in .

[0064] A yarn feeding structure 3 is provided on the upper portion of the plurality of yarn feeders 1 to guide the yarn to enter. At the same time, the yarn feeding structure 3 stabilizes the fixed installation effect of the plurality of yarn feeders 1.

[0065] In an embodiment of the present application, the yarn feeding structure 3 includes a yarn feeding plate equipped with a plurality of yarn feeding porcelain eyes 91, and a plurality of mounting holes 34 are opened on one side of the yarn feeding plate. The yarn feeding plate is fixed to the upper part of a plurality of parallel yarn feeders 1 through the plurality of mounting holes 34, so that the upper parts of the plurality of yarn feeders 1 are interlocked and fixed with the yarn feeding plate, and each yarn feeder 1 corresponds to at least one yarn feeding porcelain eye 91; a mounting portion 15 is provided at the top end of the upper part of the yarn feeder 1, and the mounting portion 15 is arranged close to the introduction end of the yarn feeder 1, and a fixing hole is provided in the mounting portion for cooperating with the mounting hole 34.

[0066] The introduction end of the yarn feeder 1 is equipped with a yarn wheel, which is driven by a motor inside the yarn feeder 1.

[0067] Specifically, the yarn feeding plate includes a mounting plate 31 and a yarn feeding carrier plate 32, a plurality of mounting holes 34 are provided on the mounting plate 31, and each mounting hole 34 on the yarn feeding carrier plate 32 is equipped with at least one yarn feeding porcelain eye 91; the top surface of the mounting portion is tilted toward the introduction end, the yarn feeding carrier plate 32 is horizontal, and the mounting plate 31 is tilted relative to the yarn feeding carrier plate 32, and the degree of inclination of the mounting plate 31 is the same as the degree of inclination of the top surface, so that after the mounting plate is fixed to the mounting portion, the yarn feeding carrier plate 32 is horizontally suspended above the introduction end.

[0068] For example, multiple yarn feeders are installed in parallel with the same spacing, and the basic conditions for installing an integrated yarn feed plate are met. The yarn feed plate can be fixedly installed based on the existing mounting position on the upper part of the yarn feeder, and one yarn feed plate can be fixed to multiple yarn feeders at the same time, thereby realizing interlocking fixation of multiple yarn feeders. Combined with the bottom fixed connection of the yarn feeder, the installation stability of multiple yarn feeders can be ensured, making it less likely to shake and highly consistent.

[0069] It can be understood that when using the yarn feed plate of the present application, after installation is completed, multiple yarn feeders maintain a relatively consistent posture, the yarn feed porcelain eyes carried by the yarn feed plate correspond to the yarn feeders, and have strong consistency. The positions of the yarn feed plate and the yarn feeders are fixed and do not change.

[0070] It should be noted that at least two yarn feeders should be interlocked and fixed with the yarn feed plate in order to enhance the stability of the overall installation structure of the yarn feeder so that it does not shake and at the same time meet the yarn feeding guiding requirements of the yarn feeder.

[0071] In an embodiment of the present application, the yarn feeding plate includes a mounting plate and a yarn feeding carrier plate for carrying a yarn feeding porcelain eye. A plurality of mounting holes are provided on the mounting plate. At least one yarn feeding porcelain eye is carried corresponding to each mounting hole on the yarn feeding carrier plate, so that each yarn feeder corresponds to at least one exclusive yarn feeding porcelain eye. When in use, the yarn feeding porcelain eye can be selected for use first, and the other yarn feeding porcelain eyes are used as backup.

[0072] In a specific embodiment, the dedicated yarn inlet porcelain eye can be matched and opened in the following manner: a yarn inlet hole is opened on the yarn inlet carrier plate directly opposite the mounting hole, and the yarn inlet porcelain eye is installed in the yarn inlet hole so that the yarn inlet porcelain eye is located directly above the introduction end.

[0073] The top of the yarn feeder is provided with a mounting portion, which is arranged close to the introduction end of the yarn feeder. A fixing hole is provided in the mounting portion, and the yarn feeding plate is fixed to the yarn feeder through the mounting hole.

[0074] It can be understood that the mounting hole is a long through hole, and the fixing hole can be a screw hole. The mounting plate can be fixed to the top of the yarn feeder by screws, and a certain mounting posture should be met to facilitate the introduction of yarn.

[0075] In a preferred embodiment, the top surface of the mounting portion is tilted toward the introduction end, the yarn feed carrier is horizontal, the mounting plate is tilted relative to the yarn feed carrier, and the degree of inclination of the mounting plate is the same as the degree of inclination of the top surface, so that after the mounting plate is fixed to the mounting portion, the yarn feed carrier is horizontally suspended above the introduction end, as shown in Figure 1.

[0076] In the embodiment of the present application, the yarn feed carrier plate can be used to carry dedicated yarn feed eyelets, and spare yarn feed eyelets can be carried on the expansion structure. They do not have a one-to-one correspondence with yarn feeders, but can be used in conjunction with similar yarn feeders. When the dedicated yarn feed eyelet needs to be replaced, the spare yarn feed eyelet can be directly replaced without waiting, stopping the machine, and delaying production.

[0077] In a specific embodiment, the yarn feed plate also includes an expansion plate, and the relative positions of the mounting plate, the yarn feed carrier plate, and the expansion plate are as follows: the mounting plate is arranged at the inner end of the yarn feed carrier plate, and the expansion plate is arranged horizontally at the outer end of the yarn feed carrier plate; a plurality of yarn feed porcelain eyes can be mounted on the expansion plate.

[0078] For example, a row of yarn feeding holes are provided at equal intervals on the outer edge of the expansion plate, such as Figure 3 As shown in , each yarn feeding hole 35 is equipped with a yarn feeding porcelain eye, and the array of yarn feeding porcelain eyes is evenly distributed relative to the plurality of yarn feeders, so that the nearest selection of each yarn feeder includes a relatively balanced selection amount.

[0079] In a feasible embodiment, a plurality of horizontal ribs 36 are provided between the expansion plate and the yarn feed carrier plate, and the yarn feed porcelain eye carried on the expansion plate is translated away from the introduction end, which can increase the distance between the yarn feed porcelain eye and the mounting portion, and can be adapted to a yarn feeder relatively far behind the mounting portion, so that the yarn feed porcelain eye has more feasible options when choosing between the nearest and the introduction end.

[0080] It can be understood that the plurality of ribs 36 are distributed at equal intervals between the yarn feeding carrier plate 32 and the capacity expansion plate 33 , and a gap is formed between two adjacent ribs 36 , as shown in FIG3 .

[0081] In this application, the yarn guiding structure 4 includes a yarn guide plate equipped with multiple yarn guide wheels 8 and multiple yarn guide porcelain eyes 92. The multiple yarn guide wheels 8 are evenly spaced on the yarn guide plate, and the multiple yarn guide porcelain eyes 92 are arranged on both sides of the yarn guide wheel 8 or on the yarn guide plate between any two adjacent yarn guide wheels 8.

[0082] The yarn guide plate includes a vertical yarn guide carrier plate 41 and a horizontal first fixed plate 42. A plurality of yarn guide grooves 411 for carrying the yarn guide wheel 8 are evenly spaced on the yarn guide carrier plate 41. The first fixed plate 42 is connected to the yarn guide carrier plate 41 on one side of the yarn guide groove 411, so that the first fixed plate 42 covers the yarn guide wheel 8 loaded in the yarn guide groove 411 and is fixed to the yarn guide wheel 8.

[0083] In this application, the yarn guide plate is equipped with two yarn passing structures, a yarn guide wheel 8 and a yarn guide porcelain eye 92, which can be distributed in a relatively uniform form, so that the yarn passing form can be switched at any position without pulling the yarn too long.

[0084] See also Figure 1 , designed according to four yarn feeders, yarn guide wheels 8 are installed at the positions corresponding to the yarn feeders on the yarn guide plate for yarn passing, and yarn guide porcelain eyes 92 are still used for yarn passing at other positions. For yarn feeders with metering behavior or requirements, the use of yarn guide wheels can minimize unnecessary friction and improve metering accuracy; while for yarn feeding structures without metering behavior or requirements, yarn guide porcelain eyes can be used for yarn passing. The yarn guide device of the present application can adapt to different yarn passing requirements and can effectively adapt to various existing yarn feeding structures.

[0085] In the embodiment of the present application, the yarn guide plate comprises a vertical yarn guide carrier plate 41, and a plurality of yarn guide grooves for carrying a yarn guide wheel are provided at equal intervals on the yarn guide carrier plate 41. On this basis, the yarn guide wheel can be installed and fixed based on the yarn guide grooves.

[0086] As another feasible embodiment, the yarn guide plate further includes a horizontal first fixing plate 42, and the yarn guide wheel is placed in the yarn guide groove 411 and fixed by the first fixing plate 42. Specifically, the first fixing plate 42 is connected to the yarn guide carrier plate on one side of the yarn guide groove, so that the fixing plate covers the yarn guide wheel loaded in the yarn guide groove 411 and is fixed to the yarn guide wheel.

[0087] For example, the upper end of the yarn guide wheel can be provided with a positioning member and a mounting hole, respectively, and the first fixing plate 42 is provided with a corresponding positioning hole and a fixing hole, so that the yarn guide wheel is fixed under the first fixing plate 42 and loaded into the yarn guide groove. The positioning member is inserted into the positioning hole, and the mounting hole corresponds to the fixing hole and is fixed by screws.

[0088] In the embodiment of the present application, the yarn guide ceramic eyelets may be provided on the yarn guide carrier plates on both sides of the yarn guide wheel or on the spare structure of the yarn guide carrier plate between two adjacent yarn guide wheels.

[0089] Yarn guide holes 412 can be opened on both sides of the yarn guide groove, and the yarn guide porcelain eyes 92 are installed in the yarn guide holes 412. For example, a yarn guide hole is opened on each side, so that one yarn guide wheel can correspond to two yarn guide porcelain eyes. When there is a switching demand, the yarn passing structure can be adjusted;

[0090] Similarly, a plurality of yarn guide holes can be provided on the yarn guide carrier plate between any adjacent yarn guide grooves, and yarn guide porcelain eyes can be installed in the yarn guide holes.

[0091] In the embodiments of the present application, the yarn guide wheel and the yarn guide porcelain eyes can be arranged alternately. The installation space occupied by the yarn guide wheel is relatively large. Therefore, the number of yarn guide porcelain eyes in each alternating setting interval can be adaptively adjusted. For example, after setting a yarn guide wheel and two corresponding yarn guide porcelain eyes, another yarn guide wheel is set, and the yarn guide eyes are alternately arranged according to this quantity ratio. It can be understood that the number of yarn guide porcelain eyes in the alternating setting interval can be adjusted according to actual conditions.

[0092] In an embodiment of the present application, the yarn guide wheel includes a cover plate 81, a base 82 and a yarn guide assembly. The cover plate and the base symmetrically snap together the yarn guide assembly to form the yarn guide wheel. A positioning piece is provided at the upper end of the cover plate, and a mounting hole is provided at the upper end of the base, so as to achieve fixed installation based on the first fixed plate 42.

[0093] Based on the installation form of the yarn guide wheel of the present application, part of the structure of the yarn guide wheel is located under the first fixed plate 42, and part of the structure passes through the yarn guide groove and is exposed outside the yarn guide carrier plate. The end exposed outside the yarn guide carrier plate is the guide front end, that is, the yarn introduction end; based on the application method of the yarn guide wheel, the guide rear end can be determined according to the yarn lead-out direction, which is not discussed in this application and is only described with the guide front end as a reference.

[0094] At the front end of the guide, a triangular support structure is provided on the base, which can be used for manual grabbing when installing based on the first fixing plate 42 to pre-place the yarn guide wheel in the yarn guide groove, thereby facilitating the positioning and screwing of the yarn guide wheel.

[0095] See also Figure 4 With the cooperation of the first fixed plate 42 and the yarn guide groove, part of the structure of the yarn guide wheel is exposed, which is the guide front end. The first fixed plate 42 and the yarn guide carrier plate form a right-angle structure, and the yarn guide wheel is loaded and fixed based on the inside of this right-angle structure.

[0096] In one embodiment of the present application, a snap fastener is provided on one side of the cover plate facing the base, and a snap fastener groove is provided on the base corresponding to the snap fastener, so that the cover plate and the base are snapped together. Figure 5 、 Figure 6 As shown in .

[0097] Based on the symmetrical buckling of the cover plate and the base, the yarn guide assembly can be loaded based on the two. After the two are symmetrically buckled, a yarn gap for guiding the yarn can be reserved. The yarn gap is connected to the yarn guide assembly, so that the introduced yarn can be wound around the yarn guide assembly and then led out, changing the running direction of the yarn. The lead-out direction can be adjusted according to actual needs.

[0098] In a feasible embodiment, the yarn guide assembly includes a guide wheel 83 and a support shaft 85. The guide wheel is rotatably arranged on the support shaft. One end of the support shaft is rotatably connected to the base, and the other end is rotatably connected to the cover plate.

[0099] The support shaft and the guide wheel can be limited, and the guide wheel can be rotated and set at a fixed position on the support shaft to prevent the guide wheel from shaking left and right. Specifically, the support shaft can be designed with a two-stage structure, with the guide wheel rotating on the middle inner shaft, and shaft cylinders are respectively installed on both sides to limit the guide wheel in the middle and form a rotational connection. The rotational connection between the support shaft and the cover plate and base can be achieved by using bearings.

[0100] In another feasible embodiment, the yarn guide assembly includes a guide wheel 83, a bearing 84 and a support shaft 85, the bearing is assembled on the support shaft, the guide wheel is assembled on the bearing, one end of the support shaft is rotatably connected to the base, and the other end is rotatably connected to the cover plate.

[0101] The inner ring of the bearing is assembled with the support shaft, preferably located in the middle of the support shaft; the outer ring of the bearing is assembled with the guide wheel. The bearing can use a deep groove ball bearing with high flexibility to ensure the rotation flexibility of the guide wheel, ensuring that the yarn can easily rotate with the guide wheel.

[0102] In a feasible embodiment, the guide front end of the cover is provided with a blocking guide rod 811, and the guide front end of the base is correspondingly provided with a guide groove 821, which is provided under the support structure. Figure 6 As shown in; the guide rod is suspended in the guide groove, as shown in Figure 5 As shown in , when the yarn is introduced, it can enter through the gap between the guide groove and the guide rod and be put on the guide wheel; at the same time, the guide rod can appropriately prevent the yarn from falling off, preventing the yarn from falling directly on the yarn guide groove and avoiding yarn wear.

[0103] In the present application, the yarn feeder 1 includes an outer shell, a motor body 5, and a main control body 6. The main control body 6 is fixed to the rear end of the motor body 5. The tail end of the rotating shaft of the motor body 5 is provided with an encoder magnet 51 that rotates synchronously with the rotating shaft. The main control body 6 is provided with an encoder chip 64 corresponding to the encoder magnet 51; after the motor body 5 and the main control body 6 are fixedly assembled, they are assembled in the outer shell.

[0104] Specifically, a main control bottom shell 61 is provided at the rear end of the motor body 5. The main control bottom shell includes a connecting part and an extending part. A through hole is provided in the center of the connecting part for accommodating the encoder magnet 51. The tail of the rotating shaft of the motor body 5 is placed in the through hole, and the extending part extends downward perpendicular to the motor body 5; it also includes a protective shell 63 and a main control board 62 that are buckled on the main control bottom shell 61. The protective shell 63 buckles the main control board 62 on the main control bottom shell 61 to form the main control body 6.

[0105] In the present application, the main control body 6 is mainly composed of the control circuit board of the yarn feeder, that is, the main control board. The main control body 6 includes a main control bottom shell, a main control board and a protective shell fixedly connected to the motor body 5, wherein the main control bottom shell is fixedly connected to the rear end of the motor body and can be fixedly connected based on the rear end shell of the motor body, but it is necessary to lead out the rotating shaft of the motor body and load the encoder magnet on it so that it corresponds to the encoder chip on the main control board, so that the main control board can obtain the rotation data of the motor body.

[0106] In a specific embodiment, an encoder chip is disposed on the front side of the main control board facing the main control bottom housing, corresponding to a through-hole, such that the encoder chip is in close proximity to the encoder magnet within the through-hole. The encoder magnet and encoder chip are disposed in close proximity, preferably with a spacing between them of 0.2 mm and 2 mm. This spacing can be adjusted based on actual accuracy requirements, or anti-interference measures can be implemented. This application describes the technical solution based on meeting these most basic requirements.

[0107] In an embodiment of the present application, a main control base shell can be set at the rear end of the motor body, and the main control board is fixedly installed on the main control base shell, and then a protective shell is provided to be buckled on the back of the main control board, that is, the protective shell buckles the main control board on the main control base shell to form the main control body.

[0108] In a specific embodiment, the main control bottom shell includes a connecting portion and an extending portion. A through hole is provided in the center of the connecting portion for accommodating the encoder magnet. The tail of the rotating shaft of the motor body is placed in the through hole, and the extending portion extends downward perpendicular to the motor body.

[0109] The main control chassis can be considered to consist of two parts: a connecting portion and an extension. The connecting portion is circular and coaxial with the motor body, while the extension connects to the lower edge of the connecting portion and extends downward for a certain length. Of course, the connecting portion and extension can be designed as an integrated unit, and based on the location of the through hole, they can be coaxially assembled and fixed to the motor body's rotating shaft.

[0110] It is understood that the width of the extension portion is the same as the maximum width or diameter of the connection, and the extension portion extends downward from the maximum width of the connection portion, such as Figure 9 As shown in .

[0111] In a specific embodiment, the downward extension length of the extension portion may be less than the length of the protective shell, that is, the overall length of the main control bottom shell is less than the length of the protective shell, so that the lower part of the front of the main control board is exposed, and this area can be set as an external control area.

[0112] The electrical connection between the main control board and the motor body can be achieved by using leads. The motor body can lead out the connecting wires from the rear end and directly welded to the main control board to achieve the control of the motor body. In this process, the leads need to pass through the main control bottom shell.

[0113] As a feasible embodiment, since the main control chassis has a through hole for accommodating the encoder magnet, the leads can also be passed through the through hole to establish an electrical connection with the main control board. However, this approach may affect the spacing between the encoder chip and the encoder magnet, or even directly cause interference. Adaptive adjustments to the through hole size and the relative position of the chip and magnet can address these shortcomings and completely eliminate or reduce these interferences.

[0114] In a preferred embodiment, the outer edge of the main control bottom shell is provided with a row of long or curved holes, through which the motor body's wiring 52 is electrically connected to the main control board. The holes are located farther away from the location of the magnets, effectively reducing the possibility of interference.

[0115] For example, the cable 52 may be a needle structure or a wire, which is led out from the rear end of the motor body to the area where the main control board is located, and the cable is welded to the corresponding interface of the main control board.

[0116] In the embodiment of the present application, after the motor body and the main control body are fixedly assembled, they can be directly transported as finished products without the need for classified transportation, which can effectively reduce the overall transportation protection cost, especially for the transportation of circuit boards.

[0117] In the present application, for the fixed assembly form of the motor body and the main control body, an outer shell can also be provided for overall protection, and external control keys, buttons, etc. can be constructed based on the outer shell to achieve basic starting control.

[0118] In a specific embodiment, the motor body and the main control body are fixedly assembled and then installed in the outer shell; an operating port is opened at the front end of the outer shell, and the operating end of the motor body is exposed through the operating port.

[0119] For example, the outer shell includes a bottom shell 12 and an outer shell 11. The motor body and the main control body are assembled in the bottom shell. The outer shell is buckled on the bottom shell, and the working end of the motor body is exposed outside the outer shell and the bottom shell. A mounting base 7 is provided at the bottom of the bottom shell. The outer shell is mounted on the mounting base 7. The mounting base 7 is used to fix the bottom shell on the working platform. The working port can be opened at the front end of the bottom shell and the outer shell, such as Figure 2 As shown in .

[0120] In the outer shell, Figure 2 As shown in the figure, the motor body is horizontal within the bottom and outer shells, while the main control body is vertical within the bottom and outer shells. Of course, other layouts are possible and can be adjusted according to the installation requirements of the work platform, such as a straight-line docking installation of the motor body and the main control body; or a docking and fixing of the motor body and the main control body at a certain angle, such as 90°, 120°, etc.

[0121] In this application, a mounting base plate 7 is provided at the bottom of the yarn feeder, and a connecting frame 73 and an inner structure plate 71 are provided on the mounting base plate 7.

The upper portion of the inner structure plate extends into the interior of the yarn feeder for positioning and installing the internal components of the yarn feeder. The internal components should at least include a motor for driving the yarn feed wheel. The motor can be an integrated motor including a motor body and a main control component. The main control component includes a control circuit board for controlling the yarn feeder.

[0124] Based on this, when the installation base plate is fixed on the working platform, the inner structure plate is also fixed synchronously; for other components positioned and installed by the inner structure plate, they are not limited to the supporting effect of the yarn feeder housing, and can share the supporting effect fixed on the working platform.

The connector is mounted based on the concave space, that is, the connecting frame and the connector are both placed inside the yarn feeder and located above the bottom sealing plate, so that after the cables are connected, the bottom of the yarn feeder can still form a relatively stable and flat bottom surface, which is convenient for being placed stably on the working platform for fixed installation.

[0126] In a specific embodiment, the connecting frame includes an inwardly recessed structural groove and fixing ears arranged on both sides of the structural groove. The structural groove is buckled onto the mounting base in an inverted manner and is fixed to the mounting base through the fixing ears on both sides. Preferably, the connector is arranged on the base of the structural groove, that is, the connector is arranged at the highest point of the connecting frame.

[0127] In order to facilitate docking with external cables, an assembly hole 72 can be opened in the center of the installation base plate, and the structural groove is buckled onto the assembly hole 72, so that the connector can be docked and connected with the external cable through the assembly hole 72.

[0128] The size of the fastening port of the structural groove at least matches the size of the assembly hole 72, so that the structural groove can block the docking hole outside the assembly hole 72, exposing only the connector without directly exposing the internal structure of the yarn feeder.

[0129] In a feasible embodiment, a snap hole is opened on the bottom plate of the structural groove, elastic snap members are provided on both sides of the connector, and the connector is snapped vertically on the bottom plate, as shown in the figure.

[0130] In an embodiment of the present application, the inner structural plate extends into the interior of the yarn feeder and can be used to assist in positioning the internal components of the installer.

The outer shell and the bottom shell are symmetrically fastened with the integrated motor to form the main structure of the yarn feeder. The mounting base is placed at the bottom of the outer shell and the bottom shell, and the bottom of the main structure (or shell structure) is blocked (retaining the external nature of the assembly hole), and the outer shell and the bottom shell are provided with fixing holes that pass through the mounting base at the diagonals, and the yarn feeder is fixed to the working platform of the yarn feeder through the fixing holes; the inner structural plate is positioned and installed on the bottom shell, and the inner structural plate is used to position and install the integrated motor.

Through holes can be opened at the four corners of the mounting base, and the assembly hole 72 is set at the center of the mounting base, so that the mounting base can be quickly installed without considering the opening of the diagonal fixing holes. Figure 2 As shown in FIG, a first fixing hole 13 and a second fixing hole 14 are provided diagonally.

[0133] The inner structure 71 includes a vertical plate 711, a limiting plate 712, and a second fixed plate 713.

A limiting plate 712 is provided on the front side of the upper end of the vertical plate 711. The limiting plate 712 is perpendicular to the plane where the vertical plate 711 is located, and a positioning hole for positioning the motor body 5 is opened in the middle of the limiting plate 712. The front end of the rotating shaft of the motor body 5 extends out through the positioning hole and is equipped with a yarn wheel to form the introduction end of the yarn feeder 1.

[0134] In specific implementation, the vertical plate can be provided with a bending structure to match the structural installation requirements of the internal components of the yarn feeder.
