[0031] The present invention will be further described below in conjunction with the accompanying drawings:

[0032] like Figure 1 As shown in FIG. 5 , the present embodiment provides a double needle bed jacquard warp knitting machine, including a jacquard mechanism, a double needle bed weaving mechanism, a comb transverse movement mechanism, a warp feeding mechanism and a pulling and curling mechanism. The warp feeding mechanism is used for supplying yarn, the pulling and curling mechanism is used for pulling out the woven cloth, and the jacquard mechanism is installed above the double needle bed weaving mechanism. The jacquard mechanism is used for changing the position where the yarn enters the double needle bed weaving mechanism, thereby enabling the double needle bed weaving mechanism to weave a pattern.

[0033] Specifically, the jacquard mechanism includes a pattern plate device 1, a pressure device 2, a thrust selection device 3, a needle lifting device 4, a plurality of vertical needle devices 5, a jacquard offset device 6 and a jacquard comb 7, a plurality of shift needles 61 are installed on the jacquard offset device 6, a plurality of jacquard yarn guide needles 71 are installed on the jacquard comb 7, a comb bar transverse movement mechanism is connected to the jacquard comb 7 by transmission to drive the jacquard comb 7 to move transversely, each shift needle 61 is embedded between two corresponding adjacent jacquard yarn guide needles 71, and when the jacquard comb 7 moves transversely, part of the shift needles 61 blocks the corresponding jacquard yarn guide needles 71, and then in the double The needle bed knitting mechanism forms a pattern under weaving, and the pressure device 2 is provided with a plurality of control grooves 21 which are arranged horizontally and equidistantly, and a pushing beam 22 is provided between each control groove 21. The thrust selection device 3 points to the pattern plate device 1, and the thrust selection device 3 falls when it points to the opening position on the pattern plate device 1, so that the thrust selection device 3 corresponds to the control groove 21. When the thrust selection device 3 corresponds to the control groove 21, the pressure device 2 will not push the thrust selection device 3, and when the thrust selection device 3 corresponds to the pushing beam 22, the pushing beam 22 pushes the thrust selection device 3.

[0034] Specifically, the needle lifting and lowering device 4 includes a needle lifting frame 41, a reset base 42 and an additional pressure control device 43. The needle lifting frame 41 is provided with a plurality of sliding holes 411. Each vertical needle device 5 can be slidably installed on the corresponding sliding hole 411. The needle lifting frame 41 is provided with a plurality of needle lifting plates 412 for hooking the corresponding vertical needle devices 5. Each additional pressure control device 43 is installed on the upper side of the needle lifting frame 41 and is connected with each sliding hole 411. The additional pressure control device 43 is connected to the air fan to generate positive and negative pressure. When the additional pressure control device 43 is connected to the positive and negative air pressure, each vertical needle device 5 is uniformly driven to rise and fall. It is worth noting that a plurality of parallel sealing beams 431 are provided at the bottom of the additional pressure control device 43, and ventilation holes connected to different fans are provided between adjacent sealing beams 431, so that the vertical needle devices 5 between adjacent sealing beams 431 can be uniformly lifted and lowered, and the control is simple, which reduces the workload of the pressurizing device 2, the thrust selection device 3 and the needle lifting and lowering device 4, and increases the service life of the warp knitting machine, with a long service life and a low failure rate.

[0035] Specifically, the reset base 42 is installed at the bottom of the needle lifting frame 41, and a reset column 421 corresponding to the sliding hole 411 is provided on the reset base 42, and each reset column 421 points to the corresponding vertical needle device 5. When the needle lifting frame 41 falls, each vertical needle device 5 is pressed on the corresponding reset column 421 and uniformly disengaged from the needle lifting plate 412, and the thrust selection device 3 pushes the corresponding vertical needle device 5 laterally to control the lateral position relationship between the vertical needle device 5 and the needle lifting plate 412. When the thrust selection device 3 pushes the vertical needle device 5, the vertical needle device 5 is away from the needle lifting plate 412 so that the vertical needle device 5 will not be lifted by the needle lifting plate 412. Each vertical needle device 5 is transmission-connected with the corresponding shift needle 61. When lifted by the needle lifting plate 412, the vertical needle device 5 drives the corresponding shift needle 61 to rise, so that the corresponding shift needle 61 is out of contact with the Jacquard guide needle 71, avoiding the shift needle 61 driving the Jacquard guide needle 71 to deflect. When the vertical needle device 5 is not lifted by the needle lifting plate 412, the corresponding shift needle 61 will not rise, so that the corresponding shift needle 61 is in contact with the Jacquard guide needle 71, and the shift needle 61 drives the Jacquard guide needle 71 to deflect. The loop forming characteristic of the Jacquard warp knitting machine is that during weaving, the lateral deviation of the Jacquard guide needle 71 is the basic characteristic of the loop forming movement of the Jacquard warp knitting machine, and the lateral deviation is caused by the action of the low shift needle 61 on the Jacquard guide needle 71 when the Jacquard comb 7 makes a relative transverse movement with the shift needle bed.

[0036] Specifically, the thrust selection device 3 includes a selection needle 31, a push needle 32, a push needle baffle 33 and a horizontal needle 34. The selection needle 31 points to the pattern plate device 1, and the push needle 32 passes through the corresponding selection needle 31. The push needle 32 is elastic and can deflect up and down under the gravity of the selection needle 31. The push needle 32 slides along the push needle baffle 33. The horizontal needle 34 is installed at the end of the push needle 32. A fork is provided on the horizontal needle 34 for clamping the vertical needle device 5. The fork is used to push the vertical needle device 5. The selection needle 31 falls and is in a low position when it points to the hole opening position on the pattern plate device 1. The selection needle 31 maintains a height and is in a high position when it points to the hole-free position on the pattern plate device 1. In the high position, the selection needle 31 points to the control slot 21 when it is in the high position, and points to the push beam 22 when it is in the low position. The selection needle 31 is intermittently lifted up, thereby driving the push needle 32 to rise, and then all the selection needles 31 are lowered, so that the selection needles 31 fall under the action of gravity, and the lifting and lowering position of the selection needle 31 will control the horizontal height of the push needle 32, thereby making the push needle 32 point to the control slot 21 or the push beam 22. At the same time, during the up and down process of the selection needle 31, the pressure device 2 moves away from the selection needle 31 for avoidance. The movement of the pressure device 2 and the lifting and lowering of the selection needle 31 are prior art and will not be repeated here.

[0037] Specifically, the pattern plate device 1 includes a pattern plate 11, a pattern plate bracket 12 and a pattern plate transmission wheel 13. The pattern plate 11 is provided with a plurality of openings that cooperate with the selected needle drop 31. The pattern plate 11 slides along the pattern plate bracket 12. The pattern plate 11 is provided with a transmission hole that meshes with the pattern plate transmission wheel 13. The pattern plate 11 moves under the drive of the pattern plate transmission wheel 13, so that the openings used to form the pattern move.

[0038] Specifically, the pressurizing device 2 includes a pressurizing grid and a pressurizing grid reciprocating device. The pressurizing grid reciprocating device is transmission-connected to the pressurizing grid. The pressurizing grid has a plurality of control grooves 21 that are horizontally and equidistantly arranged. A pushing beam 22 is provided between each of the control grooves 21. During the repeated movement of the pressurizing grid, the pushing pin 32 is repeatedly driven to move. The resetting of the pushing pin 32 depends on the elasticity of the spring pin 51 described later.

[0039] Specifically, the needle lifting frame 41 is connected to a needle lifting elevator, and the needle lifting elevator drives the needle lifting frame 41 to rise and fall.

[0040] Specifically, the vertical needle device 5 includes a spring needle 51, a hook needle 52, a connecting block 53, a retraction control piston 54 and a hook 55. The spring needle 51 and the hook needle 52 are both installed above the connecting block 53. The connecting block 53 is slidably installed in the sliding hole 411. The spring needle 51 is elastic. The elasticity of the spring needle 51 enables the transverse needle 34 to push the hook needle 52 so that the hook needle 52 is away from the needle lifting plate 412. When the transverse needle 34 does not push the hook needle 52, the spring needle 51 drives the hook needle 52 to reset, so that the needle lifting plate 412 lifts the hook needle 52. The retraction control piston 54 is slidably installed on the connecting block 53. On block 53, the contraction control piston 54 is connected to the hook needle 52 through a deflection rope. It is worth noting that when positive pressure gas or negative pressure gas is introduced into the additional pressure control device 43, the contraction control piston 54 drives the deflection rope, and then pulls the hook needle 52 to deflect, so that the deflection needle and the hook needle 52 are close to each other, so that the vertical needle device 5 can be raised and lowered under the drive of the additional pressure control device 43 without being interfered by the needle lifting plate 412, so that the additional pressure control device 43 can directly control the lifting and lowering of the vertical needle device 5, and the hook 55 is connected to the corresponding shift needle 61 through the wire 56, and then the shift needle 61 is driven to rise and fall through the wire 56.

[0041] Specifically, the contact position of the connecting block 53 with the sliding hole 411 is arc-shaped, so that the connecting block 53 can slightly rotate in the sliding hole 411, so that the elasticity of the spring needle 51 can drive the hook needle 52 to reset through the connecting block 53.

[0042] Specifically, an attraction magnet 57 is provided on the side of the sliding hole 411 close to the spring needle 51. The function of the attraction magnet 57 is that after the positive pressure gas or negative pressure gas is introduced into the additional pressure control device 43, when the deflection needle and the hook needle 52 approach each other, the hook needle 52 can be separated from the needle lifting plate 412, so that the additional pressure control device 43 can control the lifting and lowering of the vertical needle device 5 to prevent the lifting needle plate 412 from interfering with the vertical needle device 5. It should be noted that in order to prevent the vertical needle device 5 from falling off from the sliding hole 411, an upper limit block and a lower limit block are provided at the upper and lower positions of the connecting block 53 in the sliding hole 411.

[0043] Specifically, the Jacquard offset device 6 includes a shifting needle bed, each shifting needle 61 is slidably installed on the shifting needle bed, and the shifting needle bed is transmission-connected to a machine bed transverse movement mechanism, thereby driving each shifting needle 61 to move transversely, and the shifting needle 61 is used to drive the Jacquard yarn guide needle 71 to shift.

Those skilled in the art should understand that the present invention is not limited to the above embodiments.
