Description

Technical Field

[0001] This utility model relates to the field of warp knitting machines, and in particular to a convenient double needle bed warp knitting machine. Background Technology

[0002] Currently, in existing warp knitting machines, multiple jacquard guide bars are often mounted together with at least one wire pattern guide bar on the guide bar oscillator. This causes the steel strip of the wire pattern guide bar to be stretched obliquely when the guide bar oscillator swings back and forth along the front and back of the machine body, resulting in inaccurate needle movement during the left and right reciprocating motion of the pattern needle. Utility Model Content

[0003] This utility model provides a convenient double-needle bed warp knitting machine. Its main purpose is to overcome the defect in existing double-needle bed warp knitting machines where the jacquard guide bar and the wire flower guide bar are mounted together on the same guide bar cradle, and the wire flower guide bar is stretched obliquely, causing inaccurate needle movement.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] This disclosure provides a convenient double-needle bed warp knitting machine, including at least one machine body, at least one jacquard guide bar, and at least one steel wire pattern guide bar. The jacquard guide bar reciprocates along the front-back direction of the machine body. The jacquard guide bar is disposed on one side of the machine body. The steel wire pattern guide bar reciprocates laterally along the left-right direction of the machine body. The steel wire pattern guide bar and the jacquard guide bar are arranged at intervals. The steel wire pattern guide bar is disposed on the other side of the machine body. The yarn guiding portion of the steel wire pattern guide bar and the jacquard portion of the jacquard guide bar both face the same side.

[0006] In one possible implementation, the double-needle bed warp knitting machine is configured with a mounting section, at least one first execution section, and at least one second execution section. The jacquard guide bar is detachably mounted on a portion of the mounting section, and the wire flower guide bar is detachably mounted on another portion of the mounting section. The first execution section is used to drive the jacquard guide bar to swing, and the second execution section is used to drive the wire flower guide bar to move laterally.

[0007] In one possible implementation, the wire comb has a wire for pulling the wire comb. The second actuator includes at least one power unit for driving the wire comb to move laterally and a connector. A portion of the connector is connected to the wire comb, and another portion of the connector is coupled to the power unit. The connector includes at least one steel belt, at least one steel pulley adapted to the steel belt, at least one wire rope, and at least one wire guide wheel. The power unit includes at least one planetary reducer, at least one servo motor connected to the output end of the planetary reducer, and at least one cylinder. The steel pulley is connected to the planetary reducer. One end of the wire is connected to the steel belt, and the other end of the wire is connected to the wire rope and then connected to the cylinder via the wire guide wheel.

[0008] In one possible implementation, the jacquard comb is a wireless jacquard comb.

[0009] In one possible implementation, the guide portion of the wire comb has a flower needle.

[0010] In one possible implementation, the jacquard portion of the jacquard comb can be a yarn guide needle.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] This utility model has a simple structure and strong practicality. By setting the steel wire flower comb to move laterally back and forth along the left and right direction of the machine body, and the steel wire flower comb and the jacquard comb are set at intervals, the steel wire flower comb does not participate in the back and forth reciprocating motion, but only performs left and right reciprocating motion. This effectively solves the problem of inaccurate needle movement of the steel wire flower comb caused by the oblique stretching of the steel strip, and thus effectively improves the accuracy of needle movement of the steel wire flower comb.

This effectively solves the problem of inaccurate needle movement of the flower needle 33 of the wire flower comb 3 caused by the oblique stretching of the steel strip 17, and thus effectively improves the accuracy of needle movement of the wire flower comb 3.

[0021] Example 2, refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The difference between this second embodiment and the first embodiment is that the warp knitting machine 4 includes at least one jacquard comb bar 2, at least one wire flower comb bar 3, a mounting part 5, at least one first execution part 6, and at least one second execution part 39.

[0026] Reference Figure 4 In some embodiments, when the first actuator 6 drives the comb cradle 7, the comb cradle 7 reciprocates about the support shaft 9.

[0027] Reference Figure 4 In some embodiments, at least a portion of the comb hanger 8 is configured on the wire comb mounting base 10.

[0028] Reference Figure 4 and Figure 2 In some embodiments, the wire comb 3 includes a wire comb box 11 with at least one groove, at least one wire comb 12 embedded in the groove, a plurality of pins 33 arranged on the wire comb 12, and wires 13 for pulling the wire comb 12.

[0029] Reference Figure 1 , Figure 2 and Figure 3 In some embodiments, the second actuator 39 includes at least one power unit 15 for driving the wire comb 3 to move laterally and a connector 16.

[0030] Reference Figure 1 In some embodiments, a portion of the connector 16 is connected to the wire comb 3, and another portion of the connector 16 is coupled to the power unit 15.

[0031] Reference Figure 1 , Figure 2 and Figure 3 In some embodiments, the connector 16 includes at least one steel belt 17, at least one steel belt pulley 18 adapted to the steel belt 17, at least one steel wire rope 19, and at least one steel wire guide wheel 20.

[0032] Reference Figure 1 The power unit 15 includes at least one planetary reducer 21, at least one servo motor 22 connected to the output end of the planetary reducer 21, and at least one cylinder 50.

[0033] Reference Figure 1 , Figure 2 and Figure 3 In some embodiments, the steel pulley 18 is connected to the planetary reducer 21, one end of the steel wire 13 is connected to the steel belt 17, and the other end of the steel wire 13 is connected to the steel wire rope 19 and then connected to the cylinder 50 via the steel wire guide wheel 20. When the cylinder 50 is kept under a constant tension under a compressed air pressure, the steel wire comb 12 is always kept in a constant corresponding position under the servo motion traction.

[0034] Reference Figure 1 and Figure 3 In some embodiments, the crossbeam 23 is configured on the top of the frame 26, which includes at least one cylinder holder 25 and at least two wall-mounted bed boards 24.

[0038] Reference Figure 4 and Figure 5 In some embodiments, the warp knitting machine 4 can be a double needle bed warp knitting machine. In the double needle bed warp knitting machine 4, the steel wire flower comb 3 is independently installed and fixed on the machine beam 23. Unlike the traditional double needle bed comb, the entire steel wire flower comb 3 does not participate in the machine's back-and-forth swing, but only makes left-right lateral movements. Therefore, the defect of inaccurate needle movement caused by the oblique stretching of the steel strip 17 of the steel wire flower comb 3 is avoided.

The oscillation curves of the front and rear needle beds can be adjusted by the needle bed swing arm connecting rod to increase or decrease the stroke so that they can match the loop extension on the steel wire flower guide bar 3, thus meeting the needs of different process products.

[0040] Reference Figure 1 and Figure 2 The needle 33 is driven by the servo motor 22 to complete the horizontal back-and-forth movement of the needle 33 through the computer control system according to different process instructions, so as to realize the production of products with different processes.

[0041] Reference Figure 4 and Figure 5 The needle bed 34, sinking bed 31, and loop release plate 30 are connected by the rotation of the main shaft cam of the machine body to form a specific double needle bed motion trajectory, realizing the product weaving process. In this embodiment, the comb cradle 7 is pushed by the first connecting rod 38 to swing.

[0042] Reference Figure 4 and Figure 5 In this embodiment, a steel wire flower comb bar 3 is added to the double needle bed warp knitting machine 4, and a jacquard comb bar 2 is used to knit jacquard fabric. Specifically, by adopting a reasonable configuration of the comb bars (steel wire flower comb bar 3 and jacquard comb bar 2), the pattern layering effect of the integrated knitting is achieved, and a double-layer fabric with multiple features such as mesh, plain fabric, pattern lining, and pile layer effect of different thicknesses is achieved.

[0043] Reference Figure 4 The jacquard comb 2 has at least one wireless jacquard comb. The number of wireless jacquard combs is determined according to the serial number of the warp knitting machine, and the specific structure of the wireless jacquard comb can be referred to Chinese Utility Model Patent (Application No.: 202223578228.8 Publication No.: CN220034835U).
