[0019] The following is combined with Figure 1-3 This application is described in further detail.

[0020] The present application discloses a height-adjustable cloth loosening machine.

[0021] Reference Figure 1-3 The height-adjustable cloth loosening machine includes a cloth loosening machine body 1, a cloth manipulation component 2, a transmission component 3, a bearing component 5, a guide component 6 and a unwinding component 7; wherein the cloth loosening component 2 is arranged on the top of the cloth loosening machine body 1, the transmission component 3 is arranged on the top of the cloth loosening machine body 1, the transmission component 3 is located above the cloth loosening component 2, the bearing component 5 is arranged on the top of the lifting seat 42, the bearing component 5 is located below the cloth loosening component 2, and the guide component 6 is configured in multiple groups, and multiple groups of guide components 6 are all arranged in the middle of the cloth loosening machine body 1, and the unwinding component 7 is arranged on one side of the cloth loosening machine body 1. The unwinding component 7 is used to place the rolled cloth, and the free end of the cloth passes around multiple groups of guide components 6, the transmission component 3 and the cloth loosening component 2 in turn, and finally the free end of the cloth is stacked and placed on the bearing component 5 under the reciprocating swinging action of the cloth loosening component 2. After the bearing component 5 and the cloth are removed together and left to stand for a predetermined time (for example, 12 hours), the cloth can be transferred to the next processing step.

[0022] The specific structure and implementation principle of the above-mentioned cloth loosening machine body 1, the specific structure and implementation principle of the cloth manipulation component 2, the specific structure and implementation principle of the transmission component 3, the specific structure and implementation principle of the bearing component 5, the specific structure and implementation principle of the guide component 6, the specific structure and implementation principle of the unwinding component 7, and the coordination method between each component are all existing technologies. For details, please refer to the cloth loosening device in a cloth loosening machine disclosed in publication number CN107585617A, which will not be repeated here.

[0023] In this embodiment, the height-adjustable cloth loosening machine also includes a lifting component 4, which is used to drive the supporting component 5 to rise / fall vertically, so that the distance between the supporting component 5 and the manipulation component 2 can be maintained in an appropriate range of values, and try to avoid the distance between the supporting component 5 and the manipulation component 2 being too large / too small, which limits the practicality of the cloth loosening machine.

[0024] Specifically, the lifting assembly 4 includes a fixed seat 41, a lifting seat 42 and a lifting mechanism 43; wherein, the fixed seat 41 is a metal plate structure, the fixed seat 41 is horizontally arranged and fixedly set at the bottom of the cloth loosening machine body 1, and the lifting seat 42 is a metal plate structure, the lifting seat 42 is horizontally arranged and movably set at the bottom of the cloth loosening machine body 1, specifically, two groups of vertical sliders 44 are fixedly set on both sides of the lifting seat 42, and vertical slide rails 45 that are slidably adapted to the vertical sliders 44 are fixedly set on both sides of the cloth loosening machine body 1; the lifting seat 42 realizes the movable setting of vertical ascent / descent through the sliding cooperation of the vertical slider 44 and the vertical slide rail 45.

[0025] The lifting mechanism 43 is connected between the fixed seat 41 and the lifting seat 42, and the lifting mechanism 43 drives the lifting seat 42 to move up and down relative to the fixed seat 41; the lifting mechanism 43 specifically includes two sets of scissor arms 431, a driving screw 432 and a driving motor 433. The middle parts of the two sets of scissor arms 431 are hinged by a preset hinge axis, and the front ends of the two sets of scissor arms 431 are hinged to the top surface of the fixed seat 41 and the bottom surface of the lifting seat 42 respectively. The tail ends of the two sets of scissor arms 431 are hinged with a horizontal slider 434. The top surface of the fixed seat 41 and the bottom surface of the lifting seat 42 are both hinged. A horizontal slide rail 435 is fixedly provided to slideably match the horizontal slider 434, and the tail ends of the two sets of scissor arms 431 are movable in the horizontal direction through the sliding cooperation between the horizontal slider 434 and the horizontal slide rail 435; the driving screw rod 432 is rotatably set on the rotating seat reserved in the fixed seat 41, and the driving screw rod 432 is threadedly connected to the horizontal slider 434 of the fixed seat 41, the driving motor 433 is a servo motor, the driving motor 433 is fixedly set on the fixed seat 41, and the output end of the driving motor 433 is connected to the driving screw rod 432 through a preset coupling.

[0026] Implementation principle: when the driving motor 433 drives the driving screw rod 432 to rotate, the driving screw rod 432 drives the horizontal slider 434 to move through the threaded connection, so that the angle between the two sets of scissor arms 431 changes, thereby realizing that the lifting mechanism 43 drives the lifting seat 42 to rise / fall vertically relative to the fixed seat 41; under this premise, the supporting assembly 5 is set on the top of the lifting seat 42, and the lifting mechanism 43 can first drive the lifting seat 42 to rise vertically relative to the fixed seat 41, so that the initial distance between the supporting assembly 5 and the manipulation assembly 2 is reduced to a suitable interval value, and try to avoid the free end of the fabric being easily blown crooked by the fan in the workshop and causing it to be unevenly placed. As the fabric stacked on the supporting assembly 5 continues to increase, the lifting mechanism 43 can drive the lifting seat 42 to fall vertically relative to the fixed seat 41, and try to avoid the distance between the supporting assembly 5 and the manipulation assembly 2 being too small to limit the maximum load-bearing capacity of the supporting assembly 5, and ultimately improve the practicality of the cloth loosening machine.

[0027] In this embodiment, two groups of lifting mechanisms 43 are configured. The two groups of lifting mechanisms 43 are arranged at intervals. The synchronous operation of the two groups of lifting mechanisms 43 can provide sufficient lifting power for the lifting seat 42.

[0028] In this embodiment, a limit frame 81 is fixedly disposed on the top of the lifting seat 42. One side of the limit frame 81 is provided with an inlet and outlet 82 that is adapted to be embedded with the supporting assembly 5. That is, the limit frame 81 has a U-shaped structure. A rotating shaft 83 is fixedly disposed on the top of the lifting seat 42, on one side of the inlet and outlet 82. A limit rod 84 is hingedly mounted on the rotating shaft 83. A contact member 85 is threadedly connected to the rotating shaft 83. The contact member 85 is an abutment rod, and an abutment spring 86 is disposed between the abutment member 85 and the limit rod 84. The abutment spring 86 abuts against the abutment member 85, creating friction between the abutment member 85 and the lifting seat 42, allowing the abutment member 85 to rotate to any position before stopping. When the supporting assembly 5 is embedded in the limit frame 81 from the inlet and outlet 82, rotating the abutment member 85 toward the inlet and outlet 82 prevents the supporting assembly 5 from sliding off the top of the lifting seat 42.

[0029] In this embodiment, the top of the lifting base 42 is provided with multiple sets of evenly distributed rolling grooves 91. Each set of rolling grooves 91 is rotatably provided with balls 92. The tops of the balls 92 are exposed outside the rolling grooves 91 and are in rolling contact with the load-bearing assembly 5. This rolling contact between the balls 92 and the load-bearing assembly 5 reduces friction between the lifting base 42 and the load-bearing assembly 5, facilitating the removal and placement of the load-bearing assembly 5.

[0030] In this embodiment, a telescopic sleeve 10 is provided between the fixing seat 41 and the lifting seat 42. The telescopic sleeve 10 is a foldable telescopic sleeve 10 tube, and the lifting mechanism 43 is located inside the telescopic sleeve 10. The telescopic sleeve 10 can isolate external dust from adhering to and accumulating inside the lifting assembly 4.

[0031] In this embodiment, multiple sets of evenly distributed telescopic limit posts 11 are disposed between the fixed base 41 and the lifting base 42. These limit telescopic limit posts 11 include fixed posts 111 fixed to the fixed base 41 and lifting posts 112 fixed to the lifting base 42. The lifting posts 112 are provided with limit holes 113 that slidably engage with the fixed posts 111. The sliding engagement between the lifting posts 112 and the fixed posts 111 creates a limit function, ensuring smoother relative lifting between the fixed base 41 and the lifting base 42.

[0032] The embodiments of this specific implementation method are all preferred embodiments of the present application and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be covered within the scope of protection of the present application.
