DETAILED DESCRIPTION

[0025] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0026] Reference Figure 1-4 A leather flattening device comprises two support rods 1, a flattening structure 2 is arranged between the two support rods 1, the flattening structure 2 comprises an unfolding part 3 and two flattening parts 4, and the two flattening parts 4 are symmetrically arranged, the unfolding part 3 comprises a lifting assembly 301, the lifting assembly 301 is composed of a motor, a screw and a sense of tension, which is the prior art, an unfolding assembly 302 is arranged on the lifting assembly 301, and two clamping assemblies 303 are arranged on the unfolding assembly 302, the flattening part 4 comprises two mounting assemblies 401, a rolling roller 402 is arranged between the two mounting assemblies 401, the rolling roller 402 is located between two connecting plates 4012 and is rotatably connected thereto, the two rolling rollers 402 correspond to the shifting plate 3031, and the two rolling rollers 402 are in contact with each other under normal conditions.

[0027] The unfolding component 302 includes two sliders 3021, and the two sliders 3021 are respectively located in a supporting rod 1. The two sliders 3021 are rotatably connected to the screw rod 3022 and the limit rod 3023, and the screw rod 3022 is located above the limit rod 3023. The limit rod 3023 is used to limit the moving plate 3031. The screw rod 3022 is provided with symmetrical oblique threads with opposite rotation directions. Both ends of the screw rod 3022 and the limit rod 3023 penetrate the moving plate 3031 and extend a part. The moving plate 3031 is threadedly and slidably connected to the screw rod 3022 and the limit rod 3023 respectively. A motor 3024 is fixedly connected to the top of one of the two sliders 3021. The motor 3024 is a prior art and is not described in detail here. The output end of the motor 3024 and the screw rod 3022 are connected through a transmission member 3025, and the transmission member 3025 is composed of two pulleys and a belt.

[0028] The clamping assembly 303 includes a shift plate 3031, and the shift plate 3031 is a hexagon, the two sharp corners of the hexagon are located in a vertical square, and face the middle of the two rolling rollers 401. A pneumatic clamp 3032 is fixedly connected to one side of the shift plate 3031. The pneumatic clamp 3032 can grasp the two corners of the leather and make the leather vertical so that it falls naturally. The pneumatic clamp 3032 is a prior art and will not be described in detail here.

[0029] The mounting assembly 401 includes a mounting box 4011 fixedly connected to the support rod 1 , a connecting plate 4012 is slidably connected inside the mounting box 4011 , and a spring 4013 is fixedly connected between one end of the connecting plate 4012 and the mounting box 4011 .

[0030] When in use, first align the two corners of the leather with the pneumatic clamps 3032, and use the pneumatic clamps 3032 to fix the two corners of the leather, and then control the output end of the motor 3024 to rotate. Since the output end of the motor 3024 is connected to the screw rod 3022 through the through-point 3025, the screw rod 3022 will rotate along with it. When the screw rod 3022 rotates, the two pneumatic clamps 3032 will move to both sides at the same time, thereby unfolding the leather. When the leather is unfolded, the motor 3024 stops rotating.

[0031] At this time, the lifting component 302 is started to move the slider 3021 upward. At this time, the unfolding component 302 will move upward with the clamping component 303 and the leather. During the upward movement, the leather will naturally fall and unfold, and the shift plate 3031 will meet the rolling roller 402. At this time, the shift plate 3031 will push the two rolling rollers 402 outward. At this time, the connecting plate 4012 will move with the rolling roller 402 and squeeze the spring 4013 until the distance between the two rolling rollers 402 is the same as the width between the shift plates 3031. As the shift plate 3031 moves, the two inclined surfaces below the shift plate 3031 will move between the two rolling rollers 402, and as the shift plate 402 moves, the distance between the two rolling rollers 402 will gradually decrease until the two rolling rollers 402 clamp the leather.

[0032] At this time, the slider 3021 continues to move upward, and with the movement of the slider 3021, the leather continues to move upward and moves relative to the warm pressing roller 402. At this time, the rolling roller 402 will roll and flatten the leather, thereby flattening it until the leather is separated from the rolling roller 402.

[0033] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and the specification only describe the principles of the utility model. The utility model may be subject to various changes and improvements without departing from the spirit and scope of the utility model. These changes and improvements fall within the scope of the utility model to be protected.
