[0033] Further, the plurality of groups of traction rollers 4 arranged in a snakelike structure are used for conveying the fiber web 29, the residence time of the fiber web 29 in the needle punching machine can be effectively prolonged, the processing times of the needle rod 1201 on the fiber web are increased, the interweaving and perforating times between fibers are further increased, and therefore the firmness and stability of the fiber web are improved.

[0034] As shown in Figure 2 , Figure 3 , Figure 8 and Figure 10 , the first driving mechanism comprises a sliding block 24, a connecting rod 25, a first lead screw 26, a second lead screw 27 and a conveying motor 28, the first lead screw 26 and the second lead screw 27 are limitingly and rotatably installed on the needle punching machine body 1, one end of the first lead screw 26 is fixedly connected with the output shaft of the conveying motor 28, the other end of the first lead screw 26 is coaxially welded with the second lead screw 27, the thread direction of the first lead screw 26 is opposite to that of the second lead screw 27, and the rear end wall of each group of rear supporting seats 2 is fixedly connected with the sliding block 24.

[0035] Further, the sliding block 24, the connecting rod 25, the first lead screw 26 and the second lead screw 27 are used in cooperation, the driving force of the conveying motor 28 can be converted into the linear and equidistant movement between the plurality of groups of rear supporting seats 2, so as to change the distance between the two adjacent groups of door-shaped needle punching frames 3, so that the processing requirements of the fiber web with different thicknesses can be met, and more accurate traction and processing can be realized.

[0036] AsFigure 8 And Figure 10 As shown in the figure, each group of sliders 24 is sleeved on the first lead screw 26 and the second lead screw 27, and the slider 24 at the right end is provided with a forward threaded hole for accommodating the first lead screw 26, and the slider 24 at the left end is provided with a reverse threaded hole for accommodating the second lead screw 27. Each group of sliders 24 is rotatably connected to a connecting rod 25, and the plurality of connecting rods 25 are connected end to end and hinged through a rotating member.

[0037] Specifically, by starting the conveying motor 28, the first lead screw 26 and the second lead screw 27 are driven to rotate. Since the threads of the first lead screw 26 and the second lead screw 27 are opposite in direction, the slider 24 at the right end and the slider 24 at the left end move towards or away from each other, thereby pushing the plurality of rear support seats 2 to move linearly and equidistantly, achieving the purpose of changing the distance between the two adjacent door-shaped needle frames 3.

[0038] As shown in the figure, Figure 3 , Figure 4 , Figure 7 and Figure 9 The second driving mechanism includes a driven shaft 8, a driven bevel gear 9, a driving bevel gear 10, and a driving shaft 11. The driven shaft 8 is provided with two limiting rotating installations in the needle punching machine body 1. The rear end of each group of rotating shafts 5 extends into the needle punching machine body 1 and is fixedly connected to a bevel gear 6. The bevel gear 6 is meshingly connected to a bevel gear 7, and the bevel gear 7 is sleeved on the driven shaft 8.

[0039] Further, through the arrangement of the bevel gear 6, the bevel gear 7, the driven shaft 8, the driven bevel gear 9, the driving bevel gear 10, and the driving shaft 11, the driving force of the motor can be converted into the synchronous rotary motion of the plurality of rotating shafts 5, and the rotating directions of the upper traction rollers 4 and the lower traction rollers 4 are opposite, thereby ensuring uniform stress on the fiber web during processing and avoiding misalignment or uneven traction, ensuring processing quality.

[0040] As shown in the figure, Figure 6 and Figure 9 The outer wall of the driven shaft 8 is provided with three groups of rectangular long grooves arranged in a rectangular array. The inner ring of the bevel gear 7 is provided with a protruding block inserted into the rectangular long groove. The end of the driven shaft 8 is coaxially fixedly connected to the driven bevel gear 9. The driven bevel gear 9 is meshingly connected to the driving bevel gear 10. The driving bevel gear 10 is fixedly sleeved on the driving shaft 11, and the driving shaft 11 is driven to rotate by the motor.

[0041] Further, by using the protruding block and the rectangular long groove in cooperation, the bevel gear 7 can be axially limited, so that the bevel gear 7 can be horizontally moved while being normally driven to rotate by the driven shaft 8.

[0042] Specifically, by starting the first motor, the main shaft 11 is driven to rotate, the main shaft 11 drives the two groups of main bevel gears 10 to rotate, the main bevel gears 10 act on the driven bevel gears 9, so that the driven bevel gears 9 drive the driven shaft 8 to rotate, under the limiting action of the protrusion and the rectangular long sliding groove, the driven shaft 8 drives a plurality of second bevel gears 7 to rotate, the second bevel gears 7 act on the second bevel gears 6, so that the rotating shaft 5 drives the traction roller 4 to rotate, because the two groups of driven bevel gears 9 are symmetrically arranged up and down, the rotation directions of the two groups of driven shafts 8 are opposite, and thus the rotating directions of the two layers of traction rollers 4 are also opposite.

[0043] As shown in Figure 6 , Figure 7 and Figure 10 , the linkage assembly includes a main push strip 16, a connecting beam 17, a reset spring 18 and a pulling strip 19, one end of the main push strip 16 is fixedly connected with the connecting beam 17, the other end of the main push strip 16 extends into the door-shaped needle holder 3 and is fixedly connected with a plurality of groups of linearly distributed push rods 15, and the inclined grooves 14 accommodating the push rods 15 are formed in the push plate 13.

[0044] Further, by cooperating the main push strip 16, the connecting beam 17, the reset spring 18 and the pulling strip 19, the elastic force of the reset spring 18 can be converted into the horizontal opposite movement of the needle plate 12, so that the needle rod 1201 is retracted into the door-shaped needle holder 3.

[0045] As shown in Figure 7 and Figure 10 , one end of the connecting beam 17 abuts against the pulling strip 19, the other end of the connecting beam 17 is fixedly connected with two groups of reset springs 18, the pulling strip 19 is transversely inserted into a plurality of groups of rear support seats 2, and the horizontal two ends of the pulling strip 19 are fixedly connected with a group of connecting rods 20, and the connecting rods 20 are connected to the main drive assembly.

[0046] Specifically, when the pulling strip 19 moves towards the front end, the connecting beam 17 pushes the main push strip 16 to also move towards the front side under the elastic force of the reset spring 18, the push rods 15 on the main push strip 16 act on the inclined grooves 14, so that the push plate 13 is forced to push the needle plate 12 to move towards the main push strip 16, thereby making the needle rod 1201 retract into the door-shaped needle holder 3.

[0047] As shown in Figure 6 and Figure 10 , the main drive assembly includes a moving frame 21, a cam 22 and a vertical rotating shaft 23, the moving frame 21 is limitingly and slidingly installed on the needle punching machine body 1, the connecting rod 20 is fixedly connected with the moving frame 21, the inner side wall of the moving frame 21 abuts against the cam 22, the vertical rotating shaft 23 is fixedly inserted into the cam 22, and the vertical rotating shaft 23 is coaxially fixedly connected with the output shaft of the second motor.

[0048] Further, by setting the mobile frame 21, cam 22 and vertical shaft 23 in cooperation, the driving force of the second motor can be converted into the rearward movement of the pull bar 19, so that the multiple sets of needle plate 12 are synchronously extended out of the door type needle frame 3 and stabbed into the fiber web.

[0049] In use, first, the conveying motor 28 is turned on to drive the first lead screw 26 and the second lead screw 27 to rotate. Since the threads of the first lead screw 26 and the second lead screw 27 are opposite in direction, the rightmost slider 24 and the leftmost slider 24 move towards or away from each other, thereby pushing the multiple sets of rear support seats 2 to move linearly and equidistantly, so as to change the spacing between the multiple sets of door type needle frames 3, to adapt to fiber webs 29 of different thicknesses.

[0050] After the adjustment is completed, the fiber web 29 is inserted from the front end of the needle loom body 1 and wound on the multiple sets of door type needle frames 3 and the multiple traction rollers 4. Then, the first motor is turned on to drive the driving shaft 11 to rotate, the driving shaft 11 drives the two sets of driving bevel gears 10 to rotate, the driving bevel gears 10 act on the driven bevel gears 9, so that the driven bevel gears 9 drive the driven shafts 8 to rotate. Under the limiting action of the protrusions and the rectangular long grooves, the driven shafts 8 drive the multiple second bevel gears 7 to rotate, the second bevel gears 7 act on the second bevel gears 6, so that the rotating shafts 5 drive the traction rollers 4 to rotate. Since the two sets of driven bevel gears 9 are symmetrically arranged up and down, the rotation directions of the two sets of driven shafts 8 are opposite, and thus the rotation directions of the upper and lower traction rollers 4 are also opposite, so as to convey the fiber web 29 from left to right.

[0051] Subsequently, the second motor is turned on to drive the vertical rotating shaft 23 to rotate, the vertical rotating shaft 23 acts on the cam 22, and the eccentric rotating cam 22 intermittently contacts the mobile frame 21, so that the mobile frame 21 pulls the pull bar 19 rearward, so that the multiple sets of needle plates 12 are synchronously extended out of the door type needle frame 3 and stabbed into the fiber web 29. When the cam 22 and the mobile frame 21 are disconnected, the pull bar 19 moves towards the front end. At this time, the main push bar 16 is pushed by the return spring 18 to move towards the front side, the push plate 13 is pushed by the main push bar 16 to move towards the main push bar 16, and the push plate 13 is pushed by the main push bar 16 to move towards the main push bar 16, so that the needle rod 1201 is retracted into the door type needle frame 3, and the above process is repeated, so as to realize the repeated piercing action of the needle rod 1201.

[0052] A main shaft box type needle loom comprises a conveying assembly. Compared with conventional needle looms, the main shaft box type needle loom has the advantages of adjustable weaving spacing, high processing precision, low energy consumption, etc., and can better meet the needs of the textile industry for fiber web processing quality and efficiency.
