Description

Technical Field

[0001] This utility model relates to the field of circular knitting machine technology, and in particular to a protective mechanism for upper jacquard pieces. Background Technology

[0002] Jacquard pieces (or simply jacquard pieces) play a crucial role in circular knitting machines. They are mainly used to control the selective movement of needles, thereby forming specific patterns on the knitted fabric. Through jacquard pieces, circular knitting machines can produce knitted fabrics with complex patterns and designs, which typically have higher added value and market competitiveness.

[0003] Jacquard pieces can be adjusted with different weaving parameters to achieve a variety of patterns and designs. This allows circular knitting machines to meet the needs of different customers and markets. Jacquard pieces can handle various yarn materials, including cotton, wool, nylon, and polyester, thus enabling the weaving of patterns on different materials.

[0004] Currently, if jacquard wafers are not protected during high-speed operation, they are prone to floating and resulting in processing quality problems. Utility Model Content

[0005] The purpose of this utility model is to address the aforementioned shortcomings in the existing technology by proposing a protective mechanism for upper jacquard pieces.

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

[0007] Design a jacquard protective mechanism for upper jacquard pieces, including an upper syringe and a connecting seat. One end of the upper syringe is provided with a jacquard piece positioning groove, and an upper jacquard piece is also installed at the upper end of the upper syringe, with the upper jacquard piece fitting into the jacquard piece positioning groove.

[0008] The connecting seat has a limiting cylinder that is fixed through it. The limiting cylinder has a limiting rod that is slidably sleeved inside it. The lower end of the limiting rod is fixed with a lifting seat. The connecting seat has a threaded sleeve that is fixed through it. The threaded sleeve has a threaded rod that is threadedly connected inside it. The lower end of the threaded rod is fixed with a rotating block. The upper end of the lifting seat is fixed with a rotating seat. The rotating block and the rotating seat are rotatably configured inside each other.

[0009] One end of the lifting seat is fixed with a jacquard sheet floating pressure block, which is fixedly assembled to the lifting seat by screws.

[0010] In detail, the upper jacquard piece is provided with a spring, and the upper syringe has a spring seat. One end of the spring is fixed inside the spring seat, and the other end of the spring is fixed to the tail of the upper jacquard piece. The spring is a tension spring structure.

[0011] In detail, a jacquard piece reset triangle is fixed on the upper syringe, and the inclined surface of the jacquard piece reset triangle is set to contact the upper jacquard piece.

[0012] In detail, a central plate is installed in the middle of the upper syringe, and one end of the central plate is fitted with the tail of the upper jacquard plate.

[0013] In detail, the upper needle is installed at the end of the upper needle cylinder away from the upper jacquard piece.

[0014] The design scheme proposed in this utility model has the following beneficial effects in application:

[0015] 1. The height of the floating pressure block on the jacquard piece is adjusted through the threaded engagement of the threaded rod and threaded sleeve. This mechanism ensures that the floating pressure block is always in the optimal position, adapting to the positional requirements of different jacquard pieces, thus guaranteeing a smooth weaving process. This height adjustment mechanism not only improves weaving efficiency but also reduces weaving quality problems caused by height mismatch.

[0016] 2. The automatic reset of the upper jacquard piece is achieved through the cooperation of a spring and a jacquard piece reset triangle. This reset mechanism ensures that the upper jacquard piece accurately resets after each knitting cycle, guaranteeing the continuity and stability of the knitting process. Simultaneously, the coordinated work of the center jacquard piece and the upper needles ensures smooth knitting, improving knitting efficiency and product quality.

[0020] 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.

[0021] Reference Figures 1-2A jacquard protective mechanism includes an upper syringe 1 and a connecting seat 4. One end of the upper syringe 1 is provided with a jacquard positioning groove 3, and an upper jacquard piece 2 is also installed at the upper end of the upper syringe 1. The upper jacquard piece 2 is fitted into the jacquard positioning groove 3.

[0022] A limiting cylinder 6 is fixedly inserted inside the connecting seat 4. A limiting rod 5 is slidably sleeved inside the limiting cylinder 6. A lifting seat 7 is fixed at the lower end of the limiting rod 5. A threaded sleeve 8 is fixedly inserted inside the connecting seat 4. A threaded rod 9 is threadedly connected inside the threaded sleeve 8. A rotating block 10 is fixed at the lower end of the threaded rod 9. A rotating seat 11 is fixed at the upper end of the lifting seat 7. The rotating block 10 and the rotating seat 11 are rotatably arranged inside each other.

[0023] One end of the lifting seat 7 is fixed with a jacquard piece floating pressure block 13. The jacquard piece floating pressure block 13 is fixedly assembled with the lifting seat 7 by screws 12. When it is necessary to adjust the height of the jacquard piece floating pressure block 13, the threaded rod 9 is rotated so that the threaded rod 9 can move relative to the threaded sleeve 8, and the rotating block 10 rotates in the rotating seat 11. In conjunction with this, the limiting rod 5 slides in the limiting cylinder 6, so that the lifting seat 7 can move up and down, thereby adjusting the height of the jacquard piece floating pressure block 13 to meet the different position requirements of the upper jacquard pieces 2.

[0024] It should be further noted that a spring 14 is provided on the upper jacquard piece 2, and a spring seat is provided on the upper syringe 1. One end of the spring 14 is fixed inside the spring seat, and the other end of the spring 14 is fixed at the tail of the upper jacquard piece 2. The spring 14 is a tension spring structure.

[0025] It should be further noted that a jacquard piece reset triangle 15 is fixed on the upper syringe 1, and the inclined surface of the jacquard piece reset triangle 15 is set to contact the upper jacquard piece 2.

[0026] It should be further noted that a central piece 16 is installed in the middle of the upper syringe 1, and one end of the central piece 16 is fitted to the tail of the upper jacquard piece 2.

[0027] It should be further noted that the upper needle cylinder 1 is equipped with an upper knitting needle 17 at the end away from the upper jacquard piece 2.

[0028] Working method: This solution achieves height adjustment of the upper pressure block 13 of the jacquard piece through the threaded engagement of the threaded rod 9 and the threaded sleeve 8. Specifically, when it is necessary to adjust the height of the upper pressure block 13 of the jacquard piece, the operator can rotate the threaded rod 9 to make the threaded rod 9 move threadedly relative to the threaded sleeve 8. Since the lower end of the threaded rod 9 is fixed with the rotating block 10, and the rotating block 10 is internally rotated with the rotating seat 11 on the lifting seat 7, the rotation of the threaded rod 9 will drive the lifting seat 7 to move up and down. At the same time, the limiting rod 5 slides in the limiting cylinder 6 to ensure the smooth movement of the lifting seat 7. Finally, the up and down movement of the lifting seat 7 will drive the upper pressure block 13 of the jacquard piece to adjust its height, thereby meeting the different position requirements of the upper jacquard piece 2. This height adjustment mechanism can ensure that the upper pressure block 13 of the jacquard piece is always in the optimal position, ensuring the smooth progress of the weaving process.

[0029] The upper jacquard piece 2 automatically resets through the cooperation of spring 14 and jacquard piece reset triangle 15. Specifically, spring 14 is fixed at the tail of the upper jacquard piece 2, and the other end of spring 14 is fixed inside the spring seat on the upper needle cylinder 1. When the upper jacquard piece 2 is lifted during the knitting process, spring 14 is stretched and stores elastic potential energy. When the knitting process is completed, spring 14 releases elastic potential energy, causing the upper jacquard piece 2 to automatically reset. At the same time, jacquard piece reset triangle 15 is fixed on the upper needle cylinder 1. The inclined surface of jacquard piece reset triangle 15 is set to contact the upper jacquard piece 2. When the upper jacquard piece 2 resets, the inclined surface of jacquard piece reset triangle 15 guides the upper jacquard piece 2 back to the initial position. This reset mechanism can ensure that the upper jacquard piece 2 can be accurately reset after each knitting, ensuring the continuity and stability of the knitting process.

[0030] The knitting of the fabric is achieved through the coordinated work of the central knitting plate 16 and the upper knitting needle 17. Specifically, the central knitting plate 16 is installed in the middle of the upper needle cylinder 1, and one end of the central knitting plate 16 is fitted with the tail of the upper jacquard piece 2. When the upper jacquard piece 2 is lifted during the knitting process, the central knitting plate 16 will prevent the tail of the upper jacquard piece 2 from moving downward, thereby ensuring the stable lifting of the upper jacquard piece 2. At the same time, the upper knitting needle 17 is installed at the end of the upper needle cylinder 1 away from the upper jacquard piece 2. The upper knitting needle 17 works in coordination with the upper jacquard piece 2 during the knitting process, and the yarn is knitted into the fabric through the movement of the needle. This coordinated working mechanism can ensure the smooth progress of the knitting process and improve knitting efficiency and product quality.
