[0073] In addition, it should be noted that, unless otherwise specified, the technical terms or scientific terms used in the present application should be understood as the usual meaning understood by those skilled in the art to which the present application belongs.

[0074] The multi-layer fabric cutting four-edge sewing all-in-one machine sequentially comprises a fabric laying mechanism, a horizontal sewing mechanism, a longitudinal sewing mechanism, and a discharge mechanism;

[0075] The fabric laying mechanism comprises a fabric feeding unit 1 and a fabric aligning unit 3. The fabric feeding unit 1 synchronously adjusts and conveys the upper and lower input fabrics through the upper and lower fabric laying mechanisms to converge on the fabric composite mechanism of the fabric aligning unit 3;

[0076] ​​​​The transverse sewing mechanism includes a transverse sewing unit 4 and a transverse material storage unit 5. The fabric alignment unit 3 adjusts the upper and lower fabrics to be aligned left and right during the conveying process of the two-way fabric feeding machine, and at the same time, the upper and lower fabrics overlap. Then, the transverse sewing unit 4 sews the left and right sides of the fabric in real time and then conveys it to the transverse material storage unit 5.

[0077] The longitudinal sewing mechanism includes a longitudinal receiving unit 7, a longitudinal sewing unit 8, and a finished product output unit 9;

[0078] The longitudinal receiving unit 7 receives the fabric directly or indirectly from the transverse storage unit 5, then pushes the fabric to the longitudinal left and right sewing modules of the longitudinal sewing unit 7 for longitudinal sewing, and then pulls the fabric out by the longitudinal gripper module of the finished product output unit 9.

[0079] The feeding unit consists of two layers of feeding mechanisms: the upper feeding mechanism consists of an upper lifting component that enables the fabric to move up and down and longitudinally during lateral movement, an upper fabric dragging component, and an upper fabric tensioning dragging component; the lower feeding mechanism consists of a lower lifting component and a lower fabric tensioning dragging component.

[0080] The upper lifting assembly includes an upper centering rod (1-1), an upper rod cylinder (1-2) for lifting the upper centering rod (1-1), and an upper fabric edge sensor (103) located on one side of the upper centering rod (1-1); the fabric dragging assembly includes a centering guide roller (1-18) docked with the upper centering rod, and a pre-stored power roller (1-4) located behind the centering guide roller (1-18); the tension dragging assembly includes an upper tension rod (1-5) docked with the pre-stored power roller (1-4).

[0081] The lower-level lifting assembly includes a lower-level first centering boom (1-6), a lower-level first boom cylinder (1-8) for lifting the lower-level first centering boom (1-6), and a lower-level first edge detection sensor (1-9) located on one side of the lower-level first boom (1-6); a lower-level second centering boom (1-7), a lower-level second boom cylinder (1-17) for lifting the lower-level second centering boom (1-7), and a lower-level second boom cylinder (1-17) located on one side of the lower-level second boom (1-6). The lower layer second edge detection sensor (1-11); the lower layer fabric tensioning and dragging assembly includes a lower layer steering roller (1-10) set between the lower layer first centering rod (1-6) and the lower layer second centering rod (1-7), a steering roller group consisting of at least two steering rollers set up vertically behind the lower layer second centering rod (1-7), and a lower layer power roller (1-15) driven by the chain of the right servo motor (1-16) set behind the steering roller group.

[0082] The upper layer lifting assembly end converges with the lower layer lifting assembly through a longitudinal opposite edge conveying belt (3-6) and converges in the fabric composite mechanism (3-7).

[0083] In the implementation, the upper layer elastic fabric is adjusted and conveyed through the upper layer laying mechanism, the lower layer inelastic fabric is adjusted and conveyed through the lower layer laying mechanism, and the upper layer elastic fabric and the lower layer inelastic fabric converge in the fabric composite mechanism (3-7) of the fabric alignment unit. In the process, the upper layer centering pick-up upper layer edge sensor (1-3) sends a signal to the corresponding controller by sensing the fabric edge, and the controller can control the upper layer pick-up cylinder (1-2) to drive the upper layer centering pick-up rod (1-1) to swing upward or downward in the longitudinal direction, thereby controlling the adjustment action of the longitudinal movement of the fabric in the horizontal conveying process of the upper layer laying mechanism, so that the fabric edge always remains near the upper layer edge sensor (1-3), forming a dynamic balance. The upper layer fabric then passes through the upper layer tension rod (1-5) and is dragged forward by the upper layer driving roller (3-4) of the fabric alignment unit, and the fabric passes through the upper layer No. 1 yarn separating roller (3-1) and the upper layer No. 2 yarn separating roller (3-2) to be flattened in the horizontal conveying process, flows to the longitudinal opposite edge conveying belt (3-6) of the fabric alignment unit, and then enters the fabric composite mechanism (3-7) to be compounded with the inelastic fabric conveyed by the lower layer lifting assembly.

[0084] The lower layer inelastic fabric first passes through the lower layer No. 1 centering pick-up rod (1-6), passes through the lower layer No. 1 fabric edge sensor (1-9), and then passes through the lower layer turning roller (1-10) to turn to the lower layer No. 2 centering pick-up rod (1-7). In the process, when the lower layer No. 1 fabric edge sensor (1-9) does not sense the fabric edge by judgment and sends a signal to the corresponding controller, the controller of the lower layer No. 1 pick-up cylinder (1-8) controls the lower layer No. 1 pick-up cylinder (1-8) to act, thereby driving the lower layer No. 1 centering pick-up rod (1-6) to swing upward or downward in the longitudinal direction, so that the lower layer inelastic fabric is initially aligned. Similarly, the lower layer inelastic fabric then passes through the lower layer No. 2 centering pick-up rod (1-7), then passes through the lower layer No. 2 fabric edge sensor (1-11), passes through the turning roller group composed of the turning roller (1-12), the turning roller (1-13) and the turning roller (1-14), and is dragged forward by the lower layer power roller (1-15). The right servo motor (16) of the lower layer power roller (1-15) drives through the chain transmission; the lower layer No. 2 fabric edge sensor (1-11) sends a signal to the controller controlling the lower layer No. 2 pick-up cylinder (1-17) by judging that no fabric edge is sensed, and controls the lower layer No. 2 pick-up cylinder (1-17) to drive the lower layer No. 2 centering pick-up rod (1-7) to swing upward or downward in the longitudinal direction, so that the lower layer inelastic fabric is aligned again, and the upper layer laying mechanism and the lower layer laying mechanism of the entire fabric feeding unit are aligned in the horizontal conveying and synchronized with the upper layer laying mechanism to enter the fabric composite mechanism (3-7).

[0093] Corresponding to the end surface fabric composite mechanism of the lower layer paving mechanism of the feeding unit, a lower layer No. 1 silk separating roller (3-7-5) and a No. 2 silk separating roller (3-7-6) are sequentially arranged, and after being mounted on the left and right side metal plates, a drag roller group composed of a No. 1 drag roller (3-7-19), a No. 2 drag roller (3-7-3) and a No. 3 drag roller (3-7-4) is arranged between the frame bodies of the composite frame. The upper layer fabric passes between the No. 1 drag roller (3-7-19) and the No. 2 drag roller (3-7-3), and the lower layer fabric passes between the No. 2 drag roller (3-7-3) and the No. 3 drag roller (3-7-4), so as to facilitate the separation of the upper and lower layer fabrics and forward running; the lower layer No. 1 silk separating roller (3-7-5) and the No. 2 silk separating roller (3-7-6) are respectively arranged below the composite frame and driven by a speed regulating motor (3-7-16) through a chain transmission, and the lower layer fabric is completely unfolded after passing through the two silk separating rollers;

[0094] A cotton adding mechanism is arranged below the fabric composite mechanism (3-7), and the cotton adding mechanism comprises a longitudinal moving platform (2-2) and a cotton loading vehicle (2-1) arranged above the longitudinal moving platform; and an electric cylinder (2-3) is arranged at the bottom of the longitudinal moving platform (2-2).

[0095] In the implementation, cotton with a width close to that of the fabric is loaded in the cotton loading vehicle (2-1), the cotton loading vehicle (2-1) is placed on the longitudinal moving platform (2-2) by a forklift, and then the electric cylinder (2-3) is indirectly adjusted by pressing the electric control button to ensure that the cotton is roughly aligned with the upper two layers of fabric in the transverse direction, and the two layers of fabric are synchronously dragged into the lower layer of fabric by the rear unit mechanism, and then the two layers of fabric are sewn together by the transverse sewing unit. After the subsequent sewing is completed, one side of the longitudinal sewing is left open, and the sewn semi-finished product is folded by manual work, so that the lower layer of cotton is in the middle of the two layers of fabric, forming a quilt.

[0096] The working principle of the fabric spreading mechanism is as follows: Using the lower layer of non-elastic fabric as a reference, the lower layer of non-elastic fabric moves relatively smoothly laterally after passing through the lower layer centering roller (1-6) and the lower layer centering roller (1-7). Tension is then formed between the lower layer power roller (1-15) and subsequent workstations. Adjusting the speed of the lower layer power roller controls the tension in the lower layer alignment area. The upper layer fabric passes through the upper layer first splitting roller (3-2) and the upper layer second splitting roller (3-3), and is then dragged and relaxed by the upper layer drive roller (3-4) to the inclined conveyor belt (3-6-3). It then passes through the tensioning rod frame (3-7-1). When the tensioning rod adjustment handle (3-7-2) is adjusted, the tensioning rod frame (3-7-1) rotates, thus controlling the tension of the upper layer fabric in the alignment area. After passing through the first drag roller (3-7-19) and the second splitting roller (3-7-3), the tension of the upper layer fabric in the alignment area is controlled. During this process, the upper fabric detection sensor on the left (3-7-13) and the upper fabric detection sensor on the right (3-7-10) detect whether the upper fabric on both sides is aligned with the lower fabric. The upper fabric detection sensor on the right (3-7-10) sends a signal to the corresponding controller, which then sends a command to control the inclined conveyor belt (3-6-3) to move longitudinally. When the upper fabric on the right exceeds the lower fabric, the controller controls the inclined conveyor belt (3-6-3) to move to the left until the upper fabric on the right overlaps with the lower fabric. To prevent the inclined conveyor belt (3-6-3) from moving to the left indefinitely, when it moves a certain distance to the left, the left side conveyor belt module (3-1-3) and the left lower pressure cylinder (3-1-2) of the upper bidirectional fabric distribution machine (3-1) are activated, causing the upper fabric to move to the left in advance. This ensures that the inclined conveyor belt (3-6-3) will not move to the left indefinitely. When the lower fabric on the right exceeds the upper fabric, the controller controls the inclined conveyor belt (3-6-3) to move to the right, causing the upper fabric on the right to overlap with the lower fabric. Until the upper layer of fabric overlaps with the lower layer, in order to prevent the inclined conveyor belt (3-6-3) from moving continuously to the right, when it moves a certain distance to the right, the upper layer bidirectional fabric feeding machine (3-1) right side fabric feeding conveyor belt module (3-1-7) and right lower pressure cylinder (3-1-6) are activated, causing the upper layer of fabric to move to the right in advance. This ensures that the inclined conveyor belt (3-6-3) will not move continuously to the right; that is, the longitudinal movement function of the inclined conveyor belt (3-6-3) is to keep the two layers of fabric on the right side aligned.The left upper layer cloth sensing inductor (3-7-13) sends a signal to the corresponding controller, the corresponding controller sends a command to control the two lower pressure cylinders (3-7-8) to lower, and the composite part cloth poking machine (3-7-9) drives the belt to reverse, when the left upper layer cloth exceeds the lower layer cloth, the controller controls the two lower pressure cylinders (3-7-8) to lower, and the composite part cloth poking machine (3-7-9) drives the belt to reverse, so that the left upper layer cloth is pulled to the middle until the left upper layer cloth coincides with the lower layer, then the two lower pressure cylinders are lifted and the composite part cloth poking machine (3-7-9) stops rotating, when the left lower layer cloth exceeds the upper layer cloth, the controller controls the two lower pressure cylinders (3-7-8) to lower, and the composite part cloth poking machine (3-7-9) drives the belt to reverse, so that the left upper layer cloth is pulled to the side until the left upper layer cloth coincides with the lower layer, then the two lower pressure cylinders are lifted and the composite part cloth poking machine (3-7-9) stops rotating, that is, the composite part cloth poking machine (3-7-9) and the lower pressure cylinder (3-7-8) ensure that the left upper and lower layer cloths are aligned. In order to ensure the synchronization of the horizontal movement of the upper layer cloth, an upper layer cloth inductor (3-8) is installed below the upper layer driving roller, when the upper layer cloth inductor (3-8) cannot sense the cloth, it is judged that the upper layer cloth is sent too slowly, that is, the speed of the upper layer driving roller (3-4) is appropriately increased, when the upper layer cloth inductor (3-8) senses the cloth, it is judged that the upper layer cloth is sent too fast, that is, the speed of the upper layer driving roller (3-4) is appropriately reduced, so as to maintain a dynamic balance and ensure the synchronization of the upper and lower layer cloths.
