Technical Field

[0001] This utility model relates to the technical field of upper jacquard piece positioning structure, and more particularly to an upper jacquard piece positioning structure. Background Technology

[0002] The jacquard mechanism on a circular knitting machine is a key component used to weave complex patterns and designs onto knitted fabrics. The jacquard mechanism controls the selective movement of the needles, causing certain needles to be lifted or lowered during the knitting process, thereby forming specific patterns.

[0003] The jacquard mechanism controls the movement of the needles, causing certain needles to be lifted or lowered during the knitting process, thus forming specific patterns. These patterns can be simple geometric shapes or complex floral, animal, or other designs.

[0004] Currently, there are generally no milled positioning grooves, so the jacquard pieces tend to swing left and right during operation, and the speed cannot keep up. Utility Model Content

[0005] The purpose of this utility model is to address the aforementioned shortcomings in the existing technology by proposing an upper jacquard piece positioning structure.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] A jacquard piece reset triangle is installed in the middle of the upper syringe, and the end of the upper jacquard piece near the jacquard piece reset triangle is in contact with the inclined surface of the jacquard piece reset triangle.

[0010] In detail, the surface of the upper syringe is provided with a spring seat, one end of the spring is fixed in the spring seat, and the other end of the spring is fixedly connected to the surface of the upper jacquard piece.

[0015] The design scheme proposed in this utility model has the following beneficial effects in application:

[0016] 1. This solution achieves stable positioning of the upper jacquard piece through the cooperation of the spring and the positioning groove of the jacquard piece. Combined with the precise downward pressure control of the floating pressure block on the jacquard piece, it ensures the accuracy and response speed of the needle selection action. At the same time, by utilizing the inclined structure of the reset triangle and the auxiliary reset function of the spring, the upper jacquard piece can quickly return to the initial position after completing the needle selection action, reducing mechanical delay and improving knitting efficiency and pattern accuracy.

[0017] 2. It adopts a linkage structure of the center jacquard piece and the upper jacquard piece, as well as a modular design such as a split triangular seat and bolt-fixed mounting bracket, which facilitates maintenance and component replacement; the precise grooving design of the spring seat and the center jacquard piece groove further ensures the fit of each component, reduces the risk of vibration or displacement during operation, thereby improving the reliability of the overall structure and the weaving stability, and is suitable for the high-frequency production needs of complex patterns.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figures 1-3 A jacquard positioning structure includes an upper needle cylinder 1 and a mounting frame 10. A central piece 3 is provided above the upper needle cylinder 1, and upper knitting needles 2 are mounted on the surface of the upper needle cylinder 1.

[0024] One end of the upper syringe 1 is equipped with an upper jacquard piece 5. The surface of the upper syringe 1 is provided with a jacquard piece positioning groove 6. The upper jacquard piece 5 is fitted with the jacquard piece positioning groove 6. A spring 7 is provided on the upper jacquard piece 5.

[0025] A jacquard reset triangle 4 is installed in the middle of the upper syringe 1, and the end of the upper jacquard 5 near the jacquard reset triangle 4 is in contact with the inclined surface of the jacquard reset triangle 4.

[0026] It should be further noted that a spring seat is provided on the surface of the upper syringe 1, one end of the spring 7 is fixed in the spring seat, and the other end of the spring 7 is fixedly connected to the surface of the upper jacquard piece 5.

[0027] It should be further noted that the upper syringe 1 is equipped with a triangular seat for fixing the jacquard piece reset triangle 4.

[0028] It should be further noted that a jacquard sheet floating pressure block 8 is provided on one side of the mounting frame 10, and the end of the jacquard sheet floating pressure block 8 is in contact with the arc surface of the upper jacquard sheet 5.

[0029] It should be further noted that the upper jacquard piece 5 is fixedly assembled with the mounting bracket 10 by bolts 9.

[0030] It should be further noted that the upper syringe 1 has a groove for fixing the middle piece 3, and one end of the middle piece 3 is fitted with the end of the upper jacquard piece 5.

[0031] Working method: In this solution, the jacquard piece 5 is held in a stable position in the jacquard piece positioning groove 6 by the elastic force of the spring 7. At this time, the tail end of the jacquard piece 5 does not protrude from the surface of the upper needle cylinder 1, the knitting sheet is in a static state, the needle tongue is closed, and it is waiting for the needle selection signal. The middle piece 3 (middle needle pusher piece) is in a low position due to the reset triangle and does not push the knitting sheet.

[0032] The jacquard piece floating pressure block 8 is driven by the control system and moves to a specific position according to the pattern data. If jacquard is required, the jacquard piece floating pressure block 8 presses down on the tail of the corresponding upper jacquard piece 5 to overcome the spring resistance, so that the head of the jacquard piece comes out of the jacquard piece positioning groove 6 and tilts outward. If jacquard is not required, the pressure block does not work and the upper jacquard piece 5 remains in its original position.

[0033] The raised upper jacquard piece 5 rotates with the upper syringe 1 to the reset triangle area of ​​the upper jacquard piece 5. The inclined surface of the reset triangle presses the upper jacquard piece 5 back into its original position and re-locks into the jacquard piece positioning groove 6. The spring 7 assists in the reset. The unpressed upper jacquard piece 5 passes directly through the reset triangle area without any action.

[0034] The selected upper jacquard piece 5 (in the raised state) pushes the corresponding middle jacquard piece 3 upward. The middle jacquard piece 3 further lifts the fabric to the weaving height, completing actions such as padding and looping to form patterned loops. The unselected fabric pieces remain in a low position and do not participate in weaving (forming floating threads or clustered loops).

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
