Detailed Implementation

[0059] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0060] like Figures 1-9 As shown, the present invention proposes a wrinkle-free fully automatic fabric spreading machine, comprising:

[0061] Frame 1,

[0062] Fabric laying frame 2 is oscillatingly mounted on frame 1. Fabric laying frame 2 has a fabric laying plane 3. After the fabric laying frame 2 oscillates, the fabric laying plane 3 is in a horizontal or inclined state.

[0063] The fabric roll release device 4 is movably mounted on the fabric laying frame 2. The fabric output end of the fabric roll release device 4 is located above the fabric laying plane 3. The fabric roll release device 4 is used to lay the fabric on the fabric laying plane 3.

[0064] Fabric end clamping member 5 is installed on the fabric laying frame 2. The fabric end clamping member 5 is located at the beginning of the fabric laying on the fabric laying plane 3. The fabric end clamping member 5 is used to press down the end of the fabric.

[0065] When the fabric roll release device 4 lays the fabric onto the fabric laying plane 3, the fabric laying plane 3 is in an inclined state, so that the fabric is laid from a higher position to a lower position on the fabric laying plane 3.

[0066] In this embodiment, the cloth roll releasing device 4 swings the cloth laying frame 2 before laying the cloth on the cloth laying plane 3, so that the cloth laying plane 3 is in an inclined state, the cloth end pressing member 5 presses the free end of the cloth, and then the cloth roll releasing device 4 starts from the higher end of the cloth laying plane 3 and lays the cloth while moving. Since the cloth laying plane 3 is arranged in an inclined state, the cloth is subjected to the action of gravity when the cloth is laid, so that the cloth is laid more flat. When the laying is completed, the cloth is cut by the cutting knife 414. At this time, the cloth laying frame 2 is swung so that the cloth laying plane 3 is in a horizontal state, the cloth end pressing member 5 is released, and the cloth on the cloth laying plane 3 is in a free state, so that each part of the cloth is subjected to uniform force and reaches a state of uniform tightness. Regardless of how the cloth is cut later, the deformation of the cloth due to its own force is very small, and the quality of subsequent processing is improved.

[0067] Further, the cloth laying plane 3 is sequentially divided into a left flattening area, a middle flattening area, and a right flattening area along the width direction of the cloth,

[0068] The middle flattening area of the cloth laying plane 3 has a first air hole 31, and the gas flow direction of the first air hole 31 is perpendicular to the cloth laying plane 3,

[0069] The left flattening area and the right flattening area of the cloth laying plane 3 have a second air hole 32, and the second air hole 32 is arranged in an inclined state and is inclined to the left and right sides, respectively.

[0070] In this embodiment, the second air hole 32 in the left flattening area and the right flattening area blows air to the direction of the two side edges of the cloth, respectively, so as to horizontally stretch the cloth and make it more flat. In addition, the first air hole 31 in the middle flattening area blows air perpendicular to the cloth plane, which can reduce the friction between the cloth and the cloth laying plane 3, and more easily horizontally stretch the cloth by blowing air through the second air hole 32, thereby further improving the flatness of the laid cloth.

[0071] Further, the cloth roll releasing device 4 comprises,

[0072] A cloth roll moving frame 41 is movably arranged on the cloth laying frame 2,

[0073] A releasing assembly 42 is arranged on the cloth laying frame 2, and the releasing assembly 42 comprises,

[0077] The cloth roll at the cloth roll mounting part 43 is laid on the cloth laying plane 3 after being guided by the guide roller 44 and flattened by the arc-shaped flattening surface 46.

[0078] In this embodiment, the cloth roll moving frame 41 moves along the cloth laying direction, and the releasing assembly 42 is used to release the cloth. The two interact to achieve the effect of laying the cloth on the cloth laying plane 3. The cloth roll mounting part 43 is used to mount the cloth roll, which can rotate at the cloth roll mounting part 43. The guide roller 44 can facilitate the conveying direction of the cloth roll at the cloth roll mounting part 43. The arc-shaped flattening surface 46 of the cloth flattening part 45 can flatten the cloth passing through it as much as possible, achieving the functions of outputting and flattening the cloth.

[0079] Further, the arc-shaped flattening surface 46 is sequentially divided into a first flattening area and a second flattening area along the width direction of the cloth,

The third air hole 47 located in the first flattening area and the third air hole 47 located in the second flattening area are respectively inclined to the two sides of the cloth.

[0081] In this embodiment, the third air hole 47 located in the first flattening area and the third air hole 47 located in the second flattening area of the arc-shaped flattening surface 46 are respectively inclined to the two sides of the cloth. By blowing air through the third air hole 47, the cloth can be blown flat in the width direction. In addition, blowing air can also form an air film between the cloth and the arc-shaped flattening surface 46, reducing the friction between the cloth and the arc-shaped flattening surface 46, and reducing the risk of damaging the cloth. In addition, if the degree of cloth roll wrinkles is relatively high, high-temperature steam can also be blown out through the third air hole 47 to further improve the effect of flattening the cloth.

[0082] Further, the tangent surface of the arc-shaped flattening surface 46 near the cloth laying plane 3 is parallel to the cloth laying plane 3.

[0083] In this embodiment, the cloth output by the arc-shaped flattening surface 46 is as much as possible along the direction of the cloth laying plane 3, reducing the degree of cloth turning and as much as possible reducing the possibility of wrinkles.

[0093] Further, the cloth roll release device 4 further comprises,

[0094] The strip-shaped guide rail 48 is arranged on the cloth laying frame 2,

[0095] The sliding piece 49 is arranged at the bottom of the cloth roll moving frame 41, and the sliding piece 49 is arranged on the strip-shaped guide rail 48.
