[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0021] Example 1, please refer to Figures 1-5 A fabric storage rack for embroidered fabric production, comprising: The main body 100 of the placement rack is tilted. Inside the main body 100, there are two slidable material dividers: a first material divider 200 and a second material divider 300. The interior of the main body 100 is divided into three storage bins: a first storage bin 400, a second storage bin 500, and a third storage bin 600. Figures 1 to 3As shown, an additional conveying system is provided on the right side of the placement frame body 100, which can convey rolled fabric into the placement frame body 100 in one go and fill the first hopper 400. After the first hopper 400 is filled with fabric, the fabric transported by the conveying system can be moved into the second hopper 500, so that the first hopper 400, the second hopper 500 and the third hopper 600 are filled with fabric in sequence. A discharge port 701 is provided on the side of the main body 100 of the storage rack. A through rotating rod 702 is rotatably connected to the side of the main body 100 of the storage rack. A turntable 703 and a ratchet 705 are fixedly connected to the outer side of the rotating rod 702. A manual rotating rod 704 is fixedly connected to the side of the turntable 703. When it is necessary to discharge the fabric inside the main body 100 of the storage rack, a discharge port 701 is provided. Figure 4 and Figure 5 As shown, by rotating the manual lever 704 clockwise, the turntable 703, which is fixedly connected to the manual lever 704, is driven to rotate the rotating rod 702, which is fixedly connected to it, clockwise.

[0022] A pawl 707 is connected to the side of the main body 100 of the placement rack via a spring 706. The pawl 707 is located at the top of the ratchet 705 and is engaged with the ratchet 705. A separating discharge plate 708 is fixedly connected to the outer side of the rotating rod 702. Eight separating discharge plates 708 are arranged in a circumferential array about the rotating rod 702. The rotating rod 702 and the separating discharge plates 708 are located inside the main body 100 of the placement rack near the discharge port 701. When the rotating rod 702 rotates clockwise, it simultaneously drives the ratchet 705 and the separating discharge plates 708 fixedly connected to it to rotate clockwise. The clockwise rotating separating discharge plates 708 can discharge the rolled fabric in the hopper 600 through the discharge port 701 one by one, preventing multiple rolls of fabric from pouring out at once and reducing the possibility of additional wrinkles caused by compression between multiple rolls of fabric.

[0023] When the ratchet 705 is rotating clockwise, it can press the pawl 707 upward during rotation, causing the pawl 707 to stretch the spring 706 upward by a certain distance, ensuring that the ratchet 705 can rotate clockwise normally. In this way, the ratchet 705 and pawl 707 can prevent the separator discharge plate 708 from rotating in the opposite direction without the need for it to rotate.

[0024] When using, Figures 1 to 3As shown, an additional conveying system is provided on the right side of the placement rack body 100, which can convey rolled fabric into the placement rack body 100 in one go, filling the first hopper 400. Once the first hopper 400 is full, the fabric transported by the conveying system can move to the second hopper 500, so that the first hopper 400, the second hopper 500, and the third hopper 600 are sequentially filled with fabric. When it is necessary to discharge the fabric from the placement rack body 100, ... Figure 4 and Figure 5 As shown, by rotating the manual lever 704 clockwise, the turntable 703, which is fixedly connected to the manual lever 704, is driven to rotate the rotating rod 702, which is fixedly connected to it, clockwise. The rotating rod 702 simultaneously drives the ratchet 705 and the separator discharge plate 708, which are fixedly connected to it, to rotate clockwise. The separator discharge plate 708, which is rotating clockwise, can discharge the rolled fabric in the hopper 600 through the discharge port 701 in sequence. When the ratchet 705 is rotating clockwise, it can press the pawl 707 upward during the rotation, causing the pawl 707 to stretch the spring 706 upward by a certain distance, ensuring that the ratchet 705 can rotate clockwise normally. In this way, the ratchet 705 and the pawl 707 can prevent the separator discharge plate 708 from rotating in the opposite direction without the need for it to rotate.

[0025] Example 2, please refer to Figures 1-7 Based on Embodiment 1, the interior of the placement rack body 100 is equipped with an auxiliary discharge assembly 800 for improving the discharge effect. The auxiliary discharge assembly 800 includes a gear 801 fixed to the outside of the rotating rod 702. The separating discharge plate 708 is located on the side of the placement rack body 100 and is equipped with a hydraulic chamber 802. The side of the hydraulic chamber 802 is slidably connected to a transmission rod 803 by a piston. One side of the transmission rod 803 is connected to a rack 805 by a spring 804. The rack 805 is located at the top of the gear 801 and is meshed with the gear 801. The other side of the transmission rod 803 is equipped with a spring 806. When the rolled-up fabric in the hopper 600 is discharged sequentially through the discharge port 701, the rotating rod 702 rotates clockwise. At this time, the rotating rod 702 synchronously drives the gear 801 fixedly connected to it to rotate, so that the gear 801 drives the gear 805 meshing with it to move to the right. Because the elastic force of the spring 806 is greater than that of the spring 804, the gear 805 first compresses the spring 804 and moves closer to the transmission rod 803.

[0026] The gear 801 is internally rotatably connected to a baffle 807. A spring 808 is mounted on the top of the baffle 807. The hydraulic chamber 802, away from the transmission rod 803, is slidably connected to a connecting rod 809 and a connecting rod 810 by means of pistons. The connecting rod 809 is fixed to the side of the material separator 300, and the connecting rod 810 is fixed to the side of the material separator 200. After the material is discharged from the hopper 600, spring 804 is simultaneously compressed to its limit. At this point, as rotating rod 702 continues to rotate, rack 805 drives transmission rod 803 to move to the right. This, combined with hydraulic chamber 802 (which is slidably connected to transmission rod 803 via a piston) and internally connected to baffle 807, causes transmission rod 803 to move into hydraulic chamber 802. This compresses the oil within hydraulic chamber 802, causing it to flow towards connecting rod 809. This causes connecting rod 809, which is slidably connected to hydraulic chamber 802 via a piston, to move upwards. Connecting rod 809 then... The second material separator 300 moves upward, opening the second material bin 500, and the main body 100 of the placement frame is tilted, allowing the fabric in the second material bin 500 to be discharged sequentially through the rotating separator discharge plate 708. As the transmission rod 803 continues to move, the oil in the first hydraulic bin 802 pushes the baffle 807, causing the baffle 807 to compress the fourth spring 808 and rotate at a certain angle. The oil in the first hydraulic bin 802 then flows towards the side closer to the second connecting rod 810, driving the second connecting rod 810, which is slidably connected to the first hydraulic bin 802 by a piston, to move upward. The second connecting rod 810 then drives the first material separator 200 to move upward. Similarly, the fabric in the first material bin 400 can be discharged sequentially. In this way, after the fabric in hopper 3 600 is completely discharged, the fabric in hopper 2 500 and hopper 1 400 can be discharged in sequence without having to pull the material separator 1 200 and material separator 2 300 to complete the discharge, reducing the number of steps in using the device and improving its ease of use.

[0027] In use, based on Example 1, when the rolled fabric in the hopper 3 600 is discharged sequentially through the discharge port 701, the rotating rod 1 702 is in a clockwise rotation state. At this time, the rotating rod 1 702 synchronously drives the gear 801 fixedly connected to it to rotate, so that the gear 801 drives the gear 805 meshing with it to move to the right. Because the elastic force of the spring 3 806 is greater than that of the spring 2 804, the gear 805 first compresses the spring 2 804 and moves closer to the transmission rod 1 803. After the material is discharged from the hopper 600, spring 804 is simultaneously compressed to its limit. At this time, as rotating rod 702 continues to rotate, rack 805 drives transmission rod 803 to move to the right. This, in conjunction with hydraulic chamber 802 which is slidably connected to transmission rod 803 via a piston, and with baffle 807 rotatably connected inside hydraulic chamber 802, causes transmission rod 803 to move into hydraulic chamber 802, compressing the oil inside. In the case of hydraulic fluid, the oil in hydraulic chamber 802 flows preferentially towards the side closer to connecting rod 809, causing connecting rod 809, which is slidably connected to hydraulic chamber 802 via a piston, to move upwards. Connecting rod 809 then moves material separator 300 upwards, opening hopper 500. The main body 100 of the placement frame is tilted, allowing the fabric in hopper 500 to be discharged sequentially through the rotating discharge plate 708. As transmission rod 803 continues to move, the oil in hydraulic chamber 802 pushes baffle 807, causing baffle 807 to compress spring 808 and rotate at a certain angle. The oil in hydraulic chamber 802 then flows towards the side closer to connecting rod 810, causing connecting rod 810, which is slidably connected to hydraulic chamber 802 via a piston, to move upwards. Connecting rod 810 then moves material separator 200 upwards, and similarly, the fabric in hopper 400 can be discharged sequentially.

[0028] Example 3, please refer to Figures 1-9 Based on Embodiments 1 and 2, the interior of the placement rack body 100 is equipped with a cleaning assembly 900 for cleaning. The cleaning assembly 900 includes a hydraulic chamber 2 901 mounted on the side of the placement rack body 100. The bottom of the hydraulic chamber 2 901 is slidably connected to a transmission rod 2 902 via a piston. One end of the transmission rod 2 902 is connected to a force-bearing rod 904 via a spring 5 903. When the ratchet 705 is in a clockwise rotation state and the fabric inside the placement rack body 100 has been emptied, the pawl 707 reciprocates vertically under the action of the spring 1 706, causing the force-bearing rod 904, which is fixedly connected to the pawl 707, to reciprocate vertically as well.

[0029] The other end of transmission rod 2 902 is equipped with spring 6 905. The end of spring 6 905 away from transmission rod 2 902 is mounted on the inner wall of hydraulic chamber 2 901. When the force-bearing rod 904 moves reciprocally in the vertical direction, because the elastic force of spring 5 903 is greater than that of spring 6 905, the force-bearing rod 904 can drive transmission rod 2 902 to move reciprocally in the vertical direction together through spring 5 903 during the movement.

[0030] The end of the hydraulic chamber 901 furthest from the transmission rod 902 is slidably connected to an arc-shaped rod 906 via a piston. A cleaning brush 907 is rotatably connected inside the placement frame body 100, located on the side of the arc-shaped rod 906 and fixed thereto. When the transmission rod 902 moves upward, it engages with the hydraulic chamber 901, which is slidably connected to the transmission rod 902 via a piston. During this upward movement, the transmission rod 902 compresses the oil stored in the hydraulic chamber 901. The compressed oil flows towards the arc-shaped rod 906, causing the arc-shaped rod 906 to move out of the hydraulic chamber 901. Similarly, when the transmission rod 902 returns to its original position, the arc-shaped rod 906 also returns to its original position. This allows the arc-shaped rod 906 to drive the cleaning brush 907, which is fixedly connected to it, to rotate reciprocally within the placement frame body 100, performing the corresponding cleaning operation. When the ratchet 705 is rotating clockwise and the fabric inside the main body 100 of the placement rack is not emptied, the cleaning brush 907 is simultaneously restricted from rotating by the fabric and the separator 200. At this time, the transmission rod 902 is stationary, and the force rod 904 compresses the spring 903, causing it to move towards the force rod 904, thus ensuring the normal operation of the device. In this way, fabric debris inside the main body 100 of the placement rack can be cleaned to a certain extent without affecting the normal operation of the device.

[0031] In use, based on Embodiments 1 and 2, when the ratchet 705 is rotating clockwise and the fabric in the main body 100 of the placement frame has been emptied, the pawl 707 reciprocates vertically under the action of spring 706, causing the force rod 904, which is fixedly connected to the pawl 707, to reciprocate vertically as well. Because the elastic force of spring 903 is greater than that of spring 905, the force rod 904, during its movement, can drive the transmission rod 902 to reciprocate vertically as well via spring 903. When the transmission rod 902 moves upward, it cooperates with the hydraulic chamber 901, which is slidably connected to the transmission rod 902 via a piston, so that the transmission rod 902, during its upward movement, can compress the fabric originally stored in the hydraulic chamber 901. The oil is compressed and flows towards the side closer to the arc-shaped rod 906, causing the arc-shaped rod 906, which is slidably connected to the hydraulic chamber 901 via a piston, to move out of the hydraulic chamber 901. Similarly, when the transmission rod 902 resets, the arc-shaped rod 906 also resets. In this way, the arc-shaped rod 906 drives the cleaning brush 907, which is fixedly connected to it, to rotate back and forth within the placement frame body 100 to perform the corresponding cleaning operation. When the ratchet 705 is in a clockwise rotation state and the cloth in the placement frame body 100 is not emptied, the cleaning brush 907 is simultaneously restricted by the cloth and the material separator 200 and cannot rotate. At this time, the transmission rod 902 is in a stationary state, and the force rod 904 compresses the spring 903 to move towards the force rod 904, ensuring the normal use of the device.

[0032] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
