In this embodiment, the quilting adjustment drive motor 41 is a motor with forward and reverse functions.

[0028] See Figure 3 And combined Figure 1 and Figure 2 , since the function of the quilting adjustment mechanism 4 is to make the angle α between the front side of the quilting curtain 34 of the quilting mechanism 3 and the rear side of the front conveying curtain mechanism 7 ( Figure 3 The angle of the quilting curtain is increased or decreased, and the angle of the aforementioned angle α is increased as an example, that is, the front roller shaft 33a of the quilting curtain is tilted downward and the rear roller shaft 33b of the quilting curtain is raised upward as an example, the quilting adjustment drive motor 41 works clockwise, and the quilting adjustment drive reduction box 42 is driven by the quilting adjustment drive reduction box final power output shaft 422 to drive the quilting adjustment active sprocket 43, and the quilting adjustment active sprocket 43 drives the quilting curtain roller shaft left support plate shaft head sprocket 45 through the quilting adjustment transmission chain 48, and the quilting curtain roller shaft left support plate shaft head sprocket 45 drives the quilting curtain roller shaft left support plate shaft head 311 to rotate, so that the distance between the front of the quilting curtain 34 in the longitudinal direction and the front conveying curtain 75 of the structural system of the front conveying curtain mechanism 7 to be described in detail below becomes smaller, and the aforementioned non-woven fiber cotton web layer 40 is compressed more when it reaches the aforementioned front conveying curtain 75. In the above process, the cotton clamping adjustment transmission chain 48 also passes through the chain transition wheel 47 and the above chain upper and lower tensioning wheels 44, 46 are meshed (i.e. matched) with the cotton clamping adjustment transmission chain 48. Figure 3 When the first thickness Ⅰh1 of the nonwoven fiber cotton web layer 40 shown is compressed to the second thickness Ⅱh2, that is, when the first height ⅠH1 between the rear of the cotton curtain 34 and the rear conveying curtain 65 of the structural system of the rear conveying curtain mechanism 6 described in detail below is reached and the second height ⅡH2 between the front of the cotton curtain 34 and the upper surface of the front conveying curtain 75 is reached, the cotton adjustment drive motor 41 stops working, so that the cotton curtain 34 is kept at Figure 3The state shown, in which the first thickness I h1 of the non-woven fiber web layer 40 is compressed to a second thickness II h2, the compression ratio reaches 2:1 (thinner from thick). Conversely, the same example, not repeated. Of course, if the first thickness I h1 of the aforementioned non-woven fiber web layer 40 is thick or even extra thick, or too thin or even extra thin, then the aforementioned clamping power transmission mechanism 5 adjusts the clamping curtain 34 as a whole upwards or downwards.

[0029] Continuing to see Figure 1 And Figure 2 The aforementioned clamping power transmission mechanism 5 includes a transmission motor 51, a transmission reduction box 52, a main transmission sprocket 53, a power transmission chain 54, a linkage shaft right sprocket 55a, a linkage shaft left sprocket 55b, a right lifting plate connecting chain 56a, a left lifting plate connecting chain 56b, a right lifting plate connecting chain transition sprocket 57 and a left lifting plate connecting chain transition sprocket 58, the transmission motor 51 is in transmission cooperation with the transmission reduction box 52 and is provided on the transmission reduction box fixed seat 521 together with the transmission motor 51, the transmission reduction box final stage power output shaft 522 of the transmission reduction box 52 is towards the right, the aforementioned transmission reduction box fixed seat 521 is fixed on the top of the aforementioned right wall plate 2, the main transmission sprocket 53 is fixed on the transmission reduction box final stage power output shaft 522, one end of the power transmission chain 54 is sleeved on the main transmission sprocket 53, the other end is sleeved on the linkage shaft right sprocket 55a, and the linkage shaft right sprocket 55a is fixed on the right end of the aforementioned linkage shaft 30, the linkage shaft left sprocket 55b is fixed on the left end of the linkage shaft 30, the right lifting plate connecting chain transition sprocket 57 is rotatably provided on the right lifting plate connecting chain transition sprocket shaft 571 corresponding to the position below the aforementioned right lifting plate sliding accommodation cavity 21, and the right lifting plate connecting chain transition sprocket shaft 571 is fixed on the left side of the right wall plate 2, the left lifting plate connecting chain transition sprocket 58 is rotatably provided on the left lifting plate connecting chain transition sprocket shaft 581 corresponding to the position below the aforementioned left lifting plate sliding accommodation cavity 11, and the left lifting plate connecting chain transition sprocket shaft 581 is fixed on the right side of the left wall plate 1, one end of the right lifting plate connecting chain 56a is fixed with the aforementioned right lifting plate chain upper connecting ear 361, the middle part is sleeved on the aforementioned linkage shaft right sprocket 55a and right lifting plate connecting chain transition sprocket 57 in turn, and the other end of the right lifting plate connecting chain 56a is fixed with the aforementioned right lifting plate chain lower connecting ear 362, one end of the left lifting plate connecting chain 56b is fixed with the aforementioned left lifting plate chain upper connecting ear 351, the middle part is sleeved on the aforementioned linkage shaft left sprocket 55b and left lifting plate connecting chain transition sprocket 58 in turn, and the other end of the left lifting plate connecting chain 56b is fixed with the aforementioned left lifting plate chain lower connecting ear 352.

[0030] In the present embodiment, the aforementioned transmission motor 51 is a motor with a forward and reverse rotation function. A left lifting plate connecting chain limiting guide block 14 shaped like a Japanese character "T" in cross section is fixed in a spaced-apart manner from top to bottom on the right side of the aforementioned left wall plate 1 and at a position in front of the height direction corresponding to the aforementioned left lifting plate sliding accommodation cavity 11, while a right lifting plate connecting chain limiting guide block 23 shaped like a Japanese character "T" in cross section is fixed in a spaced-apart manner from top to bottom on the left side of the aforementioned right wall plate 2 and at a position in front of the height direction corresponding to the aforementioned right lifting plate sliding accommodation cavity 21, the aforementioned left lifting plate connecting chain 56b passes through the aforementioned left lifting plate connecting chain limiting guide block 14, and the aforementioned right lifting plate connecting chain 56a passes through the aforementioned right lifting plate connecting chain limiting guide block 23.

[0031] When the aforementioned cotton gripping curtain 34 is to be raised or lowered according to process requirements, taking raising as an example, the transmission motor 51 is operated, the transmission motor 51 drives the transmission reduction gearbox 52, the transmission reduction gearbox final stage power output shaft 522 drives the main transmission sprocket 53, the main transmission sprocket 53 drives the linkage shaft right sprocket 55a through the power transmission chain 54, and the linkage shaft right sprocket 55a (double-row sprocket) simultaneously drives the linkage shaft 30 and the right lifting plate connecting chain 56a. Since the two ends of the right lifting plate connecting chain 56a are fixedly connected to the right lifting plate 36 and the middle portion is sleeved on the linkage shaft right sprocket 55a and the right lifting plate connecting chain transition sprocket 57, the right lifting plate 36 is displaced upward along the aforementioned right lifting plate sliding guide 22. At the same time, the linkage shaft left sprocket 55b fixed to the left end of the linkage shaft 30 drives the left lifting plate connecting chain 56b. Since the two ends of the left lifting plate connecting chain 56b are fixedly connected to the left lifting plate 35 and the middle portion is sleeved on the linkage shaft left sprocket 55b and the left lifting plate connecting chain transition sprocket 58, the left lifting plate 35 is displaced upward along the aforementioned left lifting plate sliding guide 12, thereby displacing the cotton gripping curtain 34 upward. When the cotton gripping curtain 34 is displaced upward to the extent required by the process, the transmission motor 51 stops operating, and the cotton gripping curtain 34 is kept in the upward displacement position. Conversely, when the cotton gripping curtain 34 is to be displaced downward for adjustment, the aforementioned transmission motor 51 is simply operated in the opposite direction, and thus repeated description is omitted.

[0032] Continued to see Figure 1 and Figure 2The rear conveying curtain mechanism 6 comprises a left rear conveying curtain roller support plate 61, a right rear conveying curtain roller support plate 62, a front rear conveying curtain roller 63, a rear rear conveying curtain roller 64 and a rear conveying curtain 65.

The rear of the rear conveying curtain 65 is sleeved on the rear rear conveying curtain roller 64.

[0033] Under the action of the conveying curtain driving mechanism 8 to be described below, the right front rear conveying curtain roller shaft head 632 is driven, the front rear conveying curtain roller 63 is driven by the right front rear conveying curtain roller shaft head 632, and the rear conveying curtain 65 is driven by the front rear conveying curtain roller 63. The rear conveying curtain 65 forms a closed conveying plane around the front rear conveying curtain roller 63 and the rear rear conveying curtain roller 64, and conveys the non-woven fabric web layer 40 formed by the laying machine to the front conveying curtain mechanism 7 to be described below.

[0034] The left rear conveying curtain adjusting mechanism 50 is connected to the middle part of the left rear conveying curtain roller support plate 61, and the right rear conveying curtain adjusting mechanism 60 is connected to the middle part of the right rear conveying curtain roller support plate 62. The conveying curtain driving mechanism 8 is arranged on the right side of the left wall plate 1 and is in driving connection with the front conveying curtain mechanism 7, and is in driving connection with the right front rear conveying curtain roller shaft head 632.

[0035] Continued to see Figure 1 and Figure 2The front conveying curtain mechanism 7 comprises a front conveying curtain roller left side support plate 71, a front conveying curtain roller right side support plate 72, a front conveying curtain front curtain roller 73, a front conveying curtain rear curtain roller 74, a front conveying curtain 75, a left side support plate supporting device 76 and a right side support plate supporting device 77. The front conveying curtain roller left side support plate 71 and the front conveying curtain roller right side support plate 72 correspond to each other in left and right directions. The left end of the front conveying curtain front curtain roller 73 is rotatably supported by a bearing at the front end of the front conveying curtain roller left side support plate 71 through a front conveying curtain front curtain roller left shaft head 731. The right end of the front conveying curtain front curtain roller 73 is rotatably supported by a bearing seat at the front end of the front conveying curtain roller right side support plate 72 through a front conveying curtain front curtain roller right shaft head 732. The left end of the front conveying curtain rear curtain roller 74 is rotatably supported by a bearing seat on the aforementioned left wall plate 1 through a front conveying curtain rear curtain roller left shaft head 741 after passing through the front conveying curtain roller left side support plate 71. The right end of the front conveying curtain rear curtain roller 74 is rotatably supported by a bearing seat on the aforementioned right wall plate 2 through a front conveying curtain rear curtain roller right shaft head 742 after passing through the front conveying curtain roller right side support plate 72. The front end of the front conveying curtain 75 is sleeved on the front conveying curtain front curtain roller 73, and the rear end is sleeved on the front conveying curtain rear curtain roller 74. The left side support plate supporting device 76 is connected to the side of the front end of the front conveying curtain roller left side support plate 71 in the length direction and faces downward, and is supported on the ground floor in the use state. The right side support plate supporting device 77 is connected to the side of the front end of the front conveying curtain roller right side support plate 72 in the length direction and faces downward, and is also supported on the ground floor in the use state. The aforementioned conveying curtain driving mechanism 8 arranged on the right side of the aforementioned left wall plate 1 is in driving connection with the aforementioned front conveying curtain rear curtain roller right shaft head 742.

[0036] Continued from Figure 1 and Figure 2In the middle of the length direction of the left side support plate 61 of the rear conveying curtain roller, a rear conveying curtain roller left adjusting screw hinge ear 611 is formed on the side facing upward. The rear conveying curtain left adjusting mechanism 50 includes a rear conveying curtain left adjusting support 501, a rear conveying curtain left adjusting hand wheel 502, and a rear conveying curtain left adjusting screw 503. The rear conveying curtain left adjusting support 501 is fixed to the lower end of the rear side of the left wall plate 1 and is supported on the floor of the use site together with the left wall plate 1. The lower end of the rear conveying curtain left adjusting screw 503 is hinged to the rear conveying curtain roller left adjusting screw hinge ear 611 through a pin 5032. The middle part is threadedly engaged with a screw nut seat 5031, which is fixed to the top of the rear conveying curtain left adjusting support 501. The upper end of the rear conveying curtain left adjusting screw 503 extends upward away from the screw nut seat 5031. The rear conveying curtain left adjusting hand wheel 502 is fixed to the rear conveying curtain left adjusting screw 503 above the screw nut seat 5031. The rear conveying curtain right adjusting mechanism 60 has the same structure as the rear conveying curtain left adjusting mechanism 50 and is located opposite to the rear conveying curtain left adjusting mechanism 50.

[0037] The functions of the rear conveying curtain right adjusting mechanism 60 and the rear conveying curtain left adjusting mechanism 50 are to ensure the good connection of the height of the rear conveying curtain 65 with the laying machine of the previous process, and to smoothly deliver the non-woven fiber web layer 40 laid out by the laying machine to the rear conveying curtain 65. The rear conveying curtain left and right adjusting mechanisms 50 and 60 are adjusted simultaneously, and the degree of adjustment of both is consistent. Taking the change of the position (i.e. height) of the rear conveying curtain 65 upward or downward by adjusting the rear conveying curtain left adjusting mechanism 50 upward or downward as an example, the operator turns the rear conveying curtain left adjusting hand wheel 502 clockwise, which drives the rear conveying curtain left adjusting screw 503. Since the rear conveying curtain left adjusting screw 503 is threadedly engaged with the screw nut seat 5031, the rear conveying curtain left adjusting screw 503 can drive the rear conveying curtain roller left side support plate 61 upward through the rear conveying curtain roller left adjusting screw hinge ear 611 until the rear conveying curtain 65 is well connected with the conveying curtain of the laying machine. Conversely, if the rear conveying curtain left adjusting hand wheel 502 is turned counterclockwise, the height of the rear conveying curtain 65 is lowered.

[0038] Continued to see Figure 1 and Figure 2Since the structure of the right side support plate supporting device 77 is the same as that of the left side support plate supporting device 76, the applicant only describes the left side support plate supporting device 76 in detail. The left side support plate supporting device 76 comprises a left side support plate connecting screw 761 and a screw matching sleeve 762. The upper end of the left side support plate connecting screw 761 is hinged to the downward side of the front end of the left side support plate 71 of the front conveying curtain roller through a screw hinge pin 7611, and the lower end of the left side support plate connecting screw 761 extends into the screw matching sleeve 762 and matches the sleeve inner wall screw thread on the inner wall of the screw matching sleeve 762. A screw position adjusting locking nut 7612 is arranged on the left side support plate connecting screw 761, which is in contact with the upper end surface of the screw matching sleeve 762, and the bottom of the screw matching sleeve 762 is supported on the ground floor of the use site.

[0039] The functions of the left and right side support plate supporting devices 76 and 77 are to ensure that the height of the front conveying curtain 75 is well connected with the height of the needle punching machine inlet or the oven inlet. For example, if the front conveying curtain 75 is adjusted upward, first loosen the screw position adjusting locking nut 7612 to unlock the left side support plate connecting screw 761, then manually rotate the screw matching sleeve 762 to increase the degree of extension of the left side support plate connecting screw 761 out of the screw matching sleeve 762, so as to raise the left side support plate 71 of the front conveying curtain roller upward and raise the front conveying curtain 75 upward. After the adjustment is completed, the screw position adjusting locking nut 7612 is locked. Conversely, the height of the front conveying curtain 75 can be lowered to the required degree to adapt to the height of the needle punching machine inlet or the oven inlet by rotating the screw matching sleeve 762 in the opposite direction.

[0040] The aforementioned conveying curtain driving mechanism 8 comprises a conveying curtain driving motor 81, a conveying curtain driving reduction box 82, a conveying curtain driving driving sprocket 83, a conveying curtain driving driven sprocket 84, a conveying curtain driving chain left tension sprocket 85, a conveying curtain driving chain 86, a front conveying curtain rear curtain roller right shaft head sprocket 87a, a rear conveying curtain front curtain roller right shaft head sprocket 87b, a transition transmission chain 88 and a transition transmission chain tension sprocket 89. The conveying curtain driving motor 81 is in transmission cooperation with the conveying curtain driving reduction box 82, and is fixed to the lower end right side of the left wall plate 1 through the reduction box fixing seat together with the conveying curtain driving motor 81 and the conveying curtain driving reduction box 82. The conveying curtain driving reduction box output shaft 821 of the conveying curtain driving reduction box 82 extends to the left side of the left wall plate 1. The conveying curtain driving driving sprocket 83 is fixed on the conveying curtain driving reduction box output shaft 821. The conveying curtain driving driven sprocket 84 is fixed on the aforementioned front conveying curtain rear curtain roller left shaft head 741. The conveying curtain driving chain left tension sprocket 85 is rotatably arranged on the conveying curtain driving chain left tension sprocket shaft 851 at a position corresponding to the right side between the conveying curtain driving driving sprocket 83 and the conveying curtain driving driven sprocket 84, and the conveying curtain driving chain left tension sprocket shaft 851 is fixed to the left side of the aforementioned left wall plate 1. One end of the conveying curtain driving chain 86 is sleeved on the conveying curtain driving driving sprocket 83, and the other end is sleeved on the conveying curtain driving driven sprocket 84. The conveying curtain driving chain left tension sprocket 85 is engaged with the outer side of the conveying curtain driving chain 86. The front conveying curtain rear curtain roller right shaft head sprocket 87a is fixed on the aforementioned front conveying curtain rear curtain roller right shaft head 742. The rear conveying curtain front curtain roller right shaft head sprocket 87b is fixed on the rear conveying curtain front curtain roller right shaft head 632. The transition transmission chain tension sprocket 89 is rotatably arranged on the transition transmission chain tension sprocket shaft 891 at a position corresponding to the lower side between the front conveying curtain rear curtain roller right shaft head sprocket 87a and the rear conveying curtain front curtain roller right shaft head sprocket 87b, and the transition transmission chain tension sprocket shaft 891 is fixed to the right side of the aforementioned right wall plate 2. The transition transmission chain 88 is sleeved on the front conveying curtain rear curtain roller right shaft head sprocket 87a, the rear conveying curtain front curtain roller right shaft head sprocket 87b and the transition transmission chain tension sprocket 89.

[0041] In order to reflect the visual or neat effect of the left and right wall plates 1 and 2, and to reduce or even eliminate the non-normal invasion of non-woven fabric, as a preferred solution, a cover plate or a shield can be arranged on the left side of the left wall plate 1 and the right side of the right wall plate 2.

[0042] When the curtain drive motor 81 is working, the curtain drive motor 81 drives the curtain drive reduction box 82, and the curtain drive reduction box output shaft 821 of the curtain drive reduction box 82 drives the curtain drive driving sprocket 83, and the curtain drive driving sprocket 83 drives the curtain drive driven sprocket 84 through the curtain drive chain 86. Since the curtain drive driven sprocket 84 is fixed on the left shaft head 741 of the front curtain rear roller, the curtain drive driven sprocket 83 is driven by the curtain drive driven sprocket 84. The left shaft end 741 of the rear curtain roller of the front transport curtain drives the rear curtain roller 74 to rotate. Since the right shaft end sprocket 87a of the rear curtain roller of the front transport curtain is fixed to the right shaft end 742 of the rear curtain roller of the front transport curtain, the right shaft end sprocket 87a of the rear curtain roller of the front transport curtain drives the right shaft end sprocket 87b of the front curtain roller of the rear transport curtain through the transition transmission chain 88. The right shaft end sprocket 87b of the front curtain roller of the rear transport curtain drives the right shaft end 632 of the front curtain roller of the rear transport curtain, thereby causing the front and rear transport curtains 75 and 65 to move.

[0043] See Figure 3 And combined Figure 1 and Figure 2 During the movement of the front and rear conveying curtains 75 and 65, the rear conveying curtain 65 receives the non-woven fiber web layer 40 from the web laying machine. Assuming that the first thickness Ih1 of the non-woven fiber web layer 40 is Figure 3 As shown in the figure, under the action of the aforementioned flipping quilt adjusting mechanism 4, the first height IH1 between the rear lower surface of the quilt curtain 34 mounted on the rear roller 33b of the quilt curtain and the upper surface of the rear conveying curtain 65 and the second height IIH2 between the front lower surface of the quilt curtain 34 and the rear upper surface of the front conveying curtain 75 are formed. Figure 3 In the state shown in FIG. 1 , the angle α between the cotton-clamping curtain 34 and the front cotton-feeding curtain 75 facing each other is large enough to compress the first thickness Ⅰh1 of the non-woven fiber web layer 40 to the second thickness Ⅱh2 when it is output from the front cotton-feeding curtain 75. The non-woven fiber web layer 40 is compressed from the back to the front (with Figure 1 For example, the original thickness is 30cm, which becomes 15cm, meeting the compression ratio required by the process.

[0044] In summary, the technical solution provided by the present invention makes up for the shortcomings of the existing technology, successfully completes the invention task, and faithfully realizes the technical effects described by the applicant in the technical effect column above.
