[0025] The present utility model will be further described below with reference to the drawings:

[0026] As Figures 1-6 shown, a knitting bag flattening device includes two groups of clamping mechanisms 2 and a flattening mechanism 3. Below the clamping mechanism 2, there is an unfolding mechanism 1 for pre-flattening the knitting bag;

[0027] In this embodiment: The unfolding mechanism 1 includes a bottom plate 101. A rotating plate 102 is provided below the bottom plate 101. The rotating plate 102 is rotatably connected to the bottom plate 101. A worm 103 is provided on one side of the rotating plate 102. Teeth meshing with the worm 103 are provided on the side of the rotating plate 102 close to the worm 103. An input end of the worm 103 is fixedly provided with an unfolding motor 106. The unfolding motor 106 is fixedly connected to the bottom plate 101. Two U-shaped frames 104 are rotatably connected to the lower end of the rotating plate 102, and the two U-shaped frames 104 are symmetrically arranged about the axis of the rotating plate 102. Openings for the upper ends of the U-shaped frames 104 to pass through are provided on both sides of the bottom plate 101. Two spoke frames 105 are provided at the upper ends of the two U-shaped frames 104, and the U-shaped frames 104 are rotatably connected to the bottom ends of the spoke frames 105. Two sliders are provided on the side of the spoke frame 105 close to the bottom plate 101. A chute for the sliders of the spoke frame 105 to linearly slide is provided on the upper surface of the bottom plate 101. When the woven bag just enters the clamping mechanism 2, the woven bag needs to be pre-unfolded. The unfolding motor 106 rotates to drive the worm 103 to rotate. The worm 103 meshes with the teeth of the rotating plate 102, thereby driving the rotating plate 102 to rotate. The rotating plate 102 is rotatably connected to the U-shaped frame 104. When the rotating plate 102 rotates, the U-shaped frames 104 are pushed away in a direction away from each other, and thus the spoke frames 105 rotatably connected to the upper ends of the U-shaped frames 104 are pushed away in a direction away from each other. The sliders of the spoke frame 105 move along the chute of the bottom plate 101. The spoke frame 105 drives the two groups of clamping mechanisms 2 to move away from each other, so that the woven bag is pre-unfolded before being flattened.

[0028] In this embodiment: The flattening mechanism 3 includes a roller shaft frame 302. On the side of each of the two spoke frames 105 away from each other, there is a roller shaft frame 302, and the lower ends of the two roller shaft frames 302 are fixedly connected to the bottom plate 101. At one end of the two roller shaft frames 302 close to each other, there is a flattening roller 301 rotatably connected. Below the flattening roller 301, there is a flattening plate 303, and the lower end of the flattening plate 303 is fixedly connected to the bottom plate 101. Inside the spoke frame 105, there is a clamping mechanism 2, and the clamping mechanism 2 is composed of two clamping components distributed up and down. The clamping component includes two support rollers 203. The two support rollers 203 are symmetrically arranged at both ends of the spoke frame 105, and the support rollers 203 are rotatably connected to the spoke frame 105. A clamping belt 202 is sleeved on the two support rollers 203. On one side of each of the two spoke frames 105, there are two driving gears 204 distributed up and down. The two driving gears 204 are both fixed on the two support rollers 203 passing through the same side of the spoke frame 105. At the end of the support roller 203 on the upper side of the spoke frame 105, there is a conveying motor 201 for driving its rotation. Below the conveying motor 201, there is a motor bracket 205 for supporting it. The lower end of the motor bracket 205 is fixed on the side of the spoke frame 105. Before flattening the woven bag, the woven bag is placed between the two sets of clamping mechanisms 2. There is a gap between the upper and lower clamping components of each set of clamping mechanisms 2 to facilitate the insertion of both sides of the woven bag. The side edges of the woven bag can be clamped by the clamping belts 202 of the upper and lower clamping components. Therefore, both side edges of the woven bag can be clamped by the two sets of clamping mechanisms 2 respectively. The two symmetrically arranged conveying motors 201 operate synchronously, driving the support rollers 203 and the driving gears 204 of the upper clamping components in the two sets of clamping mechanisms 2 to rotate. At this time, the clamping belt 202 of the upper clamping component rotates. The driving gear 204 of the clamping component meshes with the driving gear 204 of the lower clamping component, causing the support roller 203 of the lower clamping component to rotate, and further causing the clamping belt 202 of the lower clamping component to rotate. At this time, the clamping belts 202 of the upper and lower clamping components of the clamping mechanism 2 rotate at the same speed in opposite directions. Therefore, the woven bag can be clamped and conveyed. The woven bag passes through the gap between the flattening plate 303 and the flattening roller 301 under the action of the clamping mechanism 2, completing the flattening of the woven bag.

[0029] Working principle: Before flattening the woven bag, the woven bag is fed between two sets of clamping mechanisms 2. There is a gap between the upper and lower clamping components of each set of clamping mechanisms 2 to facilitate the insertion of both sides of the woven bag. The side edges of the woven bag can be clamped by the clamping belts 202 of the upper and lower clamping components. Therefore, both side edges of the woven bag can be clamped by the two sets of clamping mechanisms 2 respectively. The two symmetrically arranged transmission motors 201 operate synchronously, driving the support rollers 203 and transmission gears 204 of the upper clamping components in the two sets of clamping mechanisms 2 to rotate. At this time, the clamping belts 202 of the upper clamping components rotate. The transmission gears 204 of the clamping components are meshed with the transmission gears 204 of the lower clamping components, causing the support rollers 203 of the lower clamping components to rotate, and further causing the clamping belts 202 of the lower clamping components to rotate. At this time, the clamping belts 202 on the upper and lower sides of the clamping mechanism 2 rotate at the same speed in opposite directions. Therefore, the woven bag can be clamped and conveyed. The woven bag passes through the gap between the flattening plate 303 and the flattening roller 301 under the action of the clamping mechanism 2 to complete the flattening of the woven bag;

[0030] When the woven bag just enters the clamping mechanism 2, it is necessary to pre-unfold the woven bag. The unfolding motor 106 rotates to drive the worm 103 to rotate. The worm 103 is meshed with the teeth of the rotating plate 102, thereby driving the rotating plate 102 to rotate. The rotating plate 102 is rotatably connected to the U-shaped frame 104. When the rotating plate 102 rotates, the U-shaped frame 104 is pushed away in the direction away from each other, and further the spoke frame 105 rotatably connected to the upper end of the U-shaped frame 104 is pushed away in the direction away from each other. The sliders of the spoke frame 105 move along the sliding grooves of the bottom plate 101, and the spoke frame 105 drives the two sets of clamping mechanisms 2 to move away from each other, so that the woven bag is pre-unfolded before flattening.

[0031] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principle of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed.
