Description

Technical Field

[0001] This utility model relates to the field of flat knitting machine technology, specifically to a yarn pressing mechanism for a flat knitting machine. Background Technology

[0002] The process of knitting yarn into fabric using the needles of a computerized flat knitting machine is called the looping process. In the operation of existing computerized flat knitting machines, the needles tend to carry the yarn up with them, which can lead to poor loops. Therefore, a yarn pressing mechanism is needed to ensure the stability of the yarn during the conveying process.

[0003] Currently, most common yarn pressing mechanisms on the market include structures such as pressure plates, threaded connectors, and conical springs. During use, the conical springs are used to push the pressure plates, causing the pressure plates on both sides to press and limit the conveyed yarn. However, since the springs and threaded connectors are fixedly connected, when replacing the conical springs, the threaded connectors must be turned to separate them from the threaded rods to disassemble and replace the springs. This replacement method is not only time-consuming and laborious, but also requires readjusting the downward pressure of the conical springs by turning the threaded connectors again after replacement, which is inconvenient.

[0004] Therefore, we propose a yarn pressing mechanism for a flat knitting machine to solve the above problems. Utility Model Content

This solves the problem mentioned in the background section where common yarn pressing mechanisms on the market typically include a pressure plate, threaded connectors, and conical springs. In use, the conical spring pushes the pressure plate, causing the pressure plates on both sides to press and limit the conveyed yarn. However, since the spring and threaded connector are fixedly connected, subsequent replacement of the conical spring requires twisting the threaded connector to separate it from the threaded rod. This replacement method is not only time-consuming and labor-intensive, but also requires readjusting the downward pressure of the conical spring by retightening the threaded connector, resulting in a pressure difference and inconvenience.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example

[0027] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, an embodiment of the present invention provides a yarn pressing mechanism for a flat knitting machine, including a mounting component 1, a fixed plate 2 fixedly disposed at the top center of the mounting component 1, and a screw 3 fixedly connected at the top center of the fixed plate 2.

[0028] A threaded connecting sleeve 4 is fitted on the outer ring surface of the top end of the screw 3, and a slot 5 is provided on the side wall of the threaded connecting sleeve 4. Multiple slots are evenly distributed along the center point on the outer ring surface of the threaded connecting sleeve 4, and positioning holes 6 are evenly distributed along the center point of the threaded connecting sleeve 4. A positioning hole 6 is provided on the upper surface of the threaded connecting sleeve 4. A snap-fit ​​component 7 is fitted on the outer ring surface of the threaded connecting sleeve 4, and a snap-fit ​​block 8 is fixed on the inner side wall of the snap-fit ​​component 7. The number of snap-fit ​​blocks 8 is the same as the number of slots 5, and the two are matched in size. A positioning rod 9 is provided in the inner cavity of the snap-fit ​​block 8, and an auxiliary sliding plate 10 is fitted on the bottom outer ring surface of the positioning rod 9. A return spring 11 is fixedly connected to the bottom of the positioning rod 9, and the two ends of the return spring 11 are fixedly connected to the bottom of the positioning rod 9 and the inner side wall of the snap-fit ​​block 8, respectively. A dial ring 12 is fixedly connected to the outer ring surface of the auxiliary sliding plate 10.

[0029] In use, the internal thread on the inner wall of the threaded connecting sleeve 4 is first used to connect the screw 3. After the threaded connection is completed, the locking piece 7 is fitted onto the outer ring surface of the threaded connecting sleeve 4. At this time, the dial ring 12 is moved longitudinally, and the longitudinal movement of the dial ring 12 drives the auxiliary slide plate 10 to move longitudinally inside the locking block 8, thereby causing the positioning rod 9 to retract to the inner side of the locking block 8. The positioning rod 9 will also compress the return spring 11, causing the return spring 11 to deform and generate a reverse force. Then, the locking piece 7 is rotated, and the locking piece 7 drives the locking block 8 along the outer ring of the threaded connecting sleeve 4. The surface is rotated, thereby inserting the locking block 8 into the inner side of the locking slot 5. When the locking block 8 and the locking slot 5 are fully engaged, the positioning rod 9 moves to the position directly below the positioning hole 6. At this time, the center points of the two are on the same horizontal line. Then, the longitudinal downward pressure applied to the dial ring 12 is released, and the reverse force generated by the deformation of the return spring 11 will push the positioning rod 9 in the opposite direction, thereby inserting one end of the positioning rod 9 into the positioning hole 6. This facilitates the subsequent quick connection between the locking piece 7 and the threaded connecting sleeve 4, making the whole process more convenient and faster, and more practical. It can ensure that the downward pressure of the conical spring 13 remains consistent after replacement.

[0030] like Figure 3 As shown, in some embodiments, a conical spring 13 is fixedly connected to the bottom of the snap-fit ​​7, and a lower pressure plate 14 is fixedly connected to the other end of the conical spring 13. A through hole with an inner diameter that matches the outer diameter of the threaded connecting sleeve 4 is opened at the center point of the lower pressure plate 14.

[0031] When in use, the snap fastener 7 will drive the conical spring 13 to move accordingly. After the snap fastener 7 is installed, the reverse force generated by the deformation of the conical spring 13 will push the lower pressure plate 14 in the opposite direction, so that the lower pressure plate 14 cooperates with the fixed plate 2 to press and limit the conveyed yarn.

[0032] like Figure 4 As shown, in some embodiments, a wire inlet 15 is provided on one side of the mounting member 1, and a wire outlet 16 is provided on the side of the mounting member 1 away from the wire inlet 15. The wire inlet 15 and the wire outlet 16 are located on the same horizontal line, which facilitates the subsequent yarn to pass through better.

[0033] In use, the yarn enters the inner side of the mounting part 1 through the feed port 15, passes between the two discs, and is then discharged through the outlet port 16.

[0034] like Figure 1 , Figure 3 and Figure 4 As shown, in some embodiments, the inner sidewall of the threaded connecting sleeve 4 is provided with internal threads, and the threaded connecting sleeve 4 and the screw 3 form a threaded connection.

[0035] When in use, since the threaded connection between the threaded sleeve 4 and the screw 3 is threaded, the longitudinal position height of the threaded sleeve 4 can be easily adjusted when the screw 3 rotates.

[0036] like Figure 3 As shown, in some embodiments, the positioning holes 6 are equidistantly distributed along the center point of the threaded connecting sleeve 4, and the inner diameter of the positioning holes 6 is adapted to the outer diameter of the positioning rod 9.

[0037] In use, since the number of positioning holes 6 is the same as the number of positioning rods 9, when multiple positioning rods 9 are respectively inserted into the inner side of multiple positioning holes 6, it is convenient to realize the subsequent positioning process of the snap-fit ​​part 7.

[0038] like Figure 2 As shown, in some embodiments, the positioning rod 9 is slidably connected to the locking block 8 via the return spring 11, and the positioning rod 9 is equidistantly distributed along the center point of the locking member 7;

[0039] When in use, the reverse force generated by the deformation of the return spring 11 will push the positioning rod 9 in the opposite direction, which will facilitate the subsequent input of one end of the positioning rod 9 into the inside of the positioning hole 6.

[0040] In summary, during use, the yarn enters the inner side of the mounting piece 1 through the feed port 15, passes between the two discs, and is then discharged through the outlet 16. At this time, the reverse force generated by the deformation of the conical spring 13 will push the lower pressure plate 14 in the opposite direction, thereby causing the lower pressure plate 14 to cooperate with the fixed plate 2 to press and limit the conveyed yarn. When the conical spring 13 needs to be replaced, the snap-fit ​​piece 7 is fitted onto the outer ring surface of the threaded connecting sleeve 4. At this time, the dial ring 12 is moved longitudinally, and then the longitudinal movement of the dial ring 12 drives the auxiliary slide plate 10 to move longitudinally inside the locking block 8, thereby causing the positioning rod 9 to retract to the inner side of the locking block 8, and the positioning rod 9 will squeeze The return spring 11 deforms, generating a reverse force. Then, the locking member 7 is rotated, causing the locking block 8 to rotate along the outer ring surface of the threaded connecting sleeve 4, thus inserting the locking block 8 into the inner side of the slot 5. When the locking block 8 and the slot 5 are fully engaged, the positioning rod 9 moves to directly below the positioning hole 6, at which point their center points are on the same horizontal line. Then, the longitudinal downward pressure applied to the dial ring 12 is released, and the reverse force generated by the deformation of the return spring 11 pushes the positioning rod 9 in the opposite direction, thus inserting one end of the positioning rod 9 into the positioning hole 6, facilitating the subsequent quick connection between the locking member 7 and the threaded connecting sleeve 4.

[0041] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
