Description

Technical Field

[0001] This utility model applies to the field of jacquard machines and their accessories, and particularly relates to a jacquard sheet for a computerized jacquard machine. Background Technology

[0002] With the continuous development of textile technology, the application of jacquard wafers in textile production is becoming increasingly widespread. Currently, jacquard machines typically use electronic control systems to replace traditional mechanical jacquard wafer control systems, making the jacquard process more precise and efficient. However, existing jacquard machines have the following drawbacks: 1. The design employs a bending process to address the inability to use spring clamps to prevent the jacquard wafer from springing off during machine operation. This involves bending the wafer into the needle plate, but this limits the machine's startup speed and efficiency. 2. The jacquard wafer's tail end includes a protruding needle heel, while the outer bottom edge has a recessed positioning groove serving as a fulcrum between the wafer and the needle plate. However, this groove is prone to detachment during high-speed machine operation. Based on these issues, a computer-controlled jacquard wafer design would not only eliminate the need for bending, significantly increasing machine startup speed and operating efficiency, but also be easily installed on the machine and prevent easy detachment during high-speed operation, thus effectively solving the aforementioned problems. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a computer jacquard sheet. This jacquard sheet can not only greatly increase the machine start-up speed without bending and increase the operating efficiency of the jacquard machine, but it can also be easily installed on the jacquard machine and will not easily fall off when the jacquard machine is running at high speed.

[0004] The technical solution adopted by this utility model is as follows: This utility model includes a jacquard sheet body, one end of which is a connecting end, and a U-shaped groove is provided on the connecting end. The U-shaped groove is matched with the needle receiving body for limiting. Several needle heels are integrally formed on the jacquard sheet body. The other end of the jacquard sheet body is a fixing end, and a buckle is provided on the fixing end. The buckle is matched with the elastic groove provided on the external syringe needle plate for limiting. Therefore, the jacquard body 1 is limited and engaged with the needle receiving body 2 through the U-shaped groove 10. The jacquard body 1 serves to fix and connect the needle receiving body 2. Several needle heels 11 cooperate with the external needle selection mechanism. The needle heels 11 control which needles participate in knitting and which do not, thereby forming a specific jacquard pattern. The precise design and position arrangement of the needle heels enable the jacquard machine to achieve complex jacquard patterns. The buckle 12 is limited and engaged with the elastic groove on the external needle cylinder and needle plate, forming an equilateral triangle force. The buckle 12 can maintain a relaxed state at both the upper and lower ends of the elastic groove, but it is tighter when the buckle 12 is in the middle of the elastic groove, allowing the jacquard body 1 to move flexibly within the elastic groove and maintain reliable stability in both the spring-up and pressing working states.

[0005] Furthermore, the depth-to-width ratio of the U-shaped groove is 5.0:1 to 5.5:1.

[0006] Furthermore, the number of needle heels is eight, and the eight needle heels are equidistantly arranged on one side of the jacquard piece body, and the needle heels cooperate with the external needle selection mechanism.

[0007] Furthermore, the jacquard sheet body has an elongated strip structure.

[0008] Furthermore, the jacquard piece body has a rounded corner on the side away from the needle heel shown, and the rounded corner cooperates with the outer syringe needle plate.

[0009] Furthermore, the connecting end is provided with an integrally formed reset part, which is matched with the external syringe needle plate for limiting.

[0010] Furthermore, the U-shaped opening of the U-shaped groove is constricted, and the width of the U-shaped opening is 3.50mm~3.60mm.

[0011] Furthermore, the slope formed by the eight needle heels is 1° to 2°.

[0012] Furthermore, the reset part has an L-shaped structure, which is perpendicular to the jacquard body and engages with the protrusion on the outer syringe needle plate for limiting. Attached Figure Description

[0017] like Figures 1 to 3 As shown, in this embodiment, the present invention includes a jacquard body 1, one end of which is a connecting end, and a U-shaped groove 10 is provided on the connecting end. The U-shaped groove 10 is matched with the needle receiving body 2 for limiting cooperation. A plurality of needle heels 11 are integrally formed on the jacquard body 1. The other end of the jacquard body 1 is a fixing end, and a buckle 12 is provided on the fixing end. The buckle 12 is matched with the elastic groove provided on the external syringe needle plate for limiting cooperation. Therefore, the jacquard body 1 is limited and engaged with the needle receiving body 2 through the U-shaped groove 10. The jacquard body 1 serves to fix and connect the needle receiving body 2. Several needle heels 11 cooperate with the external needle selection mechanism. The needle heels 11 control which needles participate in knitting and which do not, thereby forming a specific jacquard pattern. The precise design and position arrangement of the needle heels enable the jacquard machine to achieve complex jacquard patterns. The buckle 12 is limited and engaged with the elastic groove on the external needle cylinder and needle plate, forming an equilateral triangle force. The buckle 12 can maintain a relaxed state at both the upper and lower ends of the elastic groove, but it is tighter when the buckle 12 is in the middle of the elastic groove, allowing the jacquard body 1 to move flexibly within the elastic groove and maintain reliable stability in both the spring-up and pressing working states.

[0018] like Figure 1 As shown, in this embodiment, the depth-to-width ratio of the U-shaped groove 10 is 5.0:1 to 5.5:1. Therefore, the depth and width of the U-shaped groove 10 in this application are 24.70 mm and 4.70 mm, respectively. This depth and width allow for better contact between the jacquard body 1 and the pin 2, and also allow the pin 2 to easily enter the U-shaped groove 10, increasing stability.

[0019] like Figure 2As shown, in this embodiment, there are eight needle heels 11, which are equidistantly arranged on one side of the jacquard body 1. The needle heels 11 cooperate with an external needle selection mechanism. Therefore, by controlling which needles participate in knitting and which do not, specific jacquard patterns are formed, thus establishing the basis for complex jacquard patterns.

[0020] like Figure 1 As shown, in this embodiment, the jacquard sheet body 1 has a long strip structure. Therefore, the long strip structure of the jacquard sheet body 1 saves installation space compared to a curved design, allows for easy vertical insertion into the needle groove, greatly improves start-up speed, and increases the operating efficiency of the jacquard machine. In this patent application, the length of the jacquard sheet body 1 is 118.50 mm.

[0021] like Figure 1 As shown, in this embodiment, a rounded corner 13 is provided on the side of the jacquard body 1 away from the needle heel 11, and the rounded corner 13 cooperates with the external syringe needle plate. Therefore, the rounded corner 13 on the jacquard body 1 allows the jacquard body 1 to fit tightly against the external syringe needle plate, enhancing mutual stability.

[0022] like Figure 1 As shown, in this embodiment, the connecting end is provided with an integrally formed reset part 14, which is matched with the external syringe needle plate for limiting. Therefore, the reset part is integrally formed on the jacquard body 1, and the reset part matches the external syringe needle plate for limiting, ensuring that the jacquard body 1 can smoothly reset to its initial position after completing its work, so as to proceed with the next round of jacquard work.

[0023] like Figure 1 As shown, in this embodiment, the U-shaped opening of the U-shaped groove 10 is constricted, and the width of the U-shaped opening is 3.50mm~3.60mm. Therefore, the constricted U-shaped opening is to increase the friction with the pin body 2 when it is engaged with the pin receiving body 2, thus preventing the pin receiving body 2 from easily detaching from the jacquard piece 1.

[0024] like Figure 2 As shown, in this embodiment, the slope formed by the eight needle heels 11 is 1°~2°. Therefore, the needle heels 11 are gentler than traditional jacquard pieces, allowing the jacquard pieces to work and reset smoothly, greatly improving reliability, better adapting to the fast operation of dense needle machines, and enhancing economic efficiency.

[0025] like Figure 4As shown, in this embodiment, the reset part 14 has an L-shaped structure. The L-shaped structure is perpendicular to the jacquard body 1 and engages with the protrusion on the external syringe needle plate. Therefore, the L-shaped structure engages with the protrusion on the external syringe needle plate. After the jacquard body 1 completes the jacquard pattern, the L-shaped structure protrudes to wait for the protrusion on the external syringe needle plate to engage. After engagement, the L-shaped structure resets to allow for the next round of jacquard work.

[0026] In this embodiment, the working principle of this utility model is as follows:

[0027] like Figures 1 to 4 As shown, the needle receiving body 2 is limited and engaged with the jacquard body 1 through the U-shaped groove 10. The jacquard body 1 is limited and engaged on the external syringe needle plate through the buckle 12. The eight needle heels 11 engage with the needle feet of the external needle selector. The needle selector engages with the needle heels 11 respectively according to the instructions given by the jacquard system. When the needle selector engages with the needle heel 11, the connecting end will be raised, waiting for the external syringe needle plate to engage with the L-shaped structure, so that the jacquard body 1 can be reset and wait for the next round of jacquard work, and so on.
