[0031] See also Figures 1 to 2 The utility model provides an automatic steering machine, including a working frame 10, a steering mechanism 20 and a receiving assembly 30. First support plates 11 are provided on both sides of the top of the input end of the working frame 10. A rotating rod 12 is rotatably connected between the two first support plates 11. The rotating rod 12 is used to wrap the packaging paper. Two guide members 40 are provided on the top of the working frame 10 for guiding the paper to be transported; the steering mechanism 20 is arranged at the middle top of the working frame 10 and is located between the two guide members 40. The receiving assembly 30 is arranged at the output end of the working frame 10 for supporting the paper folded into two layers.

[0032] When in use, the end of the paper is stretched from the top of the rotating rod 12 and moved to the first guide member 40. The end of the paper is sent into the steering mechanism 20 by the transmission force provided by the first guide member 40. After the steering mechanism 20 turns, one side of the paper is turned over and lifted, and then turned downward to press the other side of the paper, so that the paper is folded into a two-layer state. Then, the two-layer paper is sent to the receiving assembly 30 through the second guide member 40, which is convenient for the subsequent heat sealing process. The turning mechanism 20 turns the single-layer paper into a two-layer paper, which reduces manual operations and improves efficiency.

[0033] Please also read Figure 3 ,in, Figure 3(a) in the figure shows, from top to bottom, the curved folding diagrams of the paper at different positions of the lifting section 211, (b) is a cross-sectional view of the folding section 212, (c) is a cross-sectional view of the pressing section 213, and (d) is a cross-sectional view of the flat section 214. The steering mechanism 20 includes an upper pressing plate 21, a lower pressing plate 22 and a limit rod 23. The lower pressing plate 22 is suspended above the work frame 10 through a support plate 25. One side of the upper pressing plate 21 is fixedly connected to one side of the lower pressing plate 22. The connection between the upper pressing plate 21 and the lower pressing plate 22 has a smooth transition. The upper pressing plate 21 includes an upper lifting section 211, a folding section 212, a lower pressing section 213 and a gentle section 214. The upper lifting section 211, the folding section 212, the lower pressing section 213 and the gentle section 214 are integrally formed. The upper lifting section 211, the folding section 212, the lower pressing section 213 and the gentle section 214 are fixedly connected to one side of the lower pressing plate 22 in sequence, and the lower pressing section 213 and the gentle section 214 are arranged above the lower pressing plate 22. The limit rod 23 is arranged between the upper pressing plate 21 and the lower pressing plate 22, and there is a gap between the limit rod 23 and the connection between the upper pressing plate 21 and the lower pressing plate 22. The limit rod 23 is fixedly connected to the working frame 10 through the connecting rod 26. The side of the single-layer paper that is lifted and turned over is defined as the movable side, and the other side of the single-layer paper is defined as the fixed side.

[0034] When the first guide member 40 transfers the single-layer paper to the lower pressing plate 22, the single-layer paper is located below the limiting rod 23; as the single-layer paper continues to extend into the upper lifting section 211, the movable side of the single-layer paper in the upper lifting section 211 will be lifted and flipped upward, so that the angle between the movable side and the fixed side gradually decreases from 180 degrees to 120 degrees; then the single-layer paper enters the folding section 212, at which time the single-layer paper begins to flip and fold downward, and the angle between the movable side and the fixed side gradually decreases to an acute angle; when the single-layer paper enters the lower pressing section 213, the angle of the movable side of the single-layer paper flipping downward increases sharply, so that the angle between the movable side and the fixed side continues to gradually decrease until the angle between the movable side and the fixed side gradually approaches 0 degrees, and then the single-layer paper enters the flat section 214, at which time the distance between the movable side and the fixed side is smaller than that in the lower pressing section 213, and the paper is formed into two layers. The limiting rod 23 is always in close contact with the connection between the movable side and the fixed side, playing a limiting and guiding role.

[0035] Preferably, the sides of the lower pressing plate 22 and the upper pressing plate 21 that are away from the limiting rod 23 are fixed with limiting pieces 24, one limiting piece 24 is arranged obliquely and in a V-shape with the lower pressing plate 22, and the other limiting piece 24 is arranged obliquely and in a V-shape with the upper pressing plate 21. The limiting rod 23 and the limiting piece 24 both terminate at the lower pressing section 213. The two limiting pieces 24 are arranged to limit the paper, so as to prevent the paper from sliding to the outside between the lower pressing plate 22 and the upper pressing plate 21.

[0036] Please also read Figure 4 In this embodiment, the guide member 40 includes a second support plate 41. Two second support plates 41 are fixedly provided on both sides of the top of the work frame 10. Two shafts 42 spaced apart from each other are rotatably provided between the two second support plates 41. Rollers 43 are fixedly provided on the outer sides of the two shafts 42. A gap is provided between the two rollers 43 for paper to pass through. Anti-slip sleeves are fixedly provided on the outer sides of the two rollers 43 to increase the friction between the paper and the rollers 43, so that the paper can be driven to move after the rollers 43 rotate.

[0037] Among them, the guide member 40 also includes a driving motor 44, which is fixedly arranged at the bottom of the work frame 10. One end of the rotating shaft 42 located at the bottom rotates through the second support plate 41 to extend to the outer wall and is fixed with a sprocket 45 and a gear 47. The output shaft of the driving motor 44 is fixed with a sprocket 45, and the two sprockets 45 are rotatably connected by a chain 46. One end of the rotating shaft 42 located at the top rotates through the second support plate 41 to extend to the outer wall and is fixed with a gear 47, and the two gears 47 are meshed and connected.

[0038] By starting the driving motor 44, the two rollers 43 start to rotate; then the end of the single-layer paper is sent between the two rollers 43, and the end of the single-layer paper is driven forward to between the lower pressing plate 22 and the upper pressing plate 21 by the squeezing rotation of the two rollers 43.

[0039] Preferably, the guide member 40 also includes two limit plates 48, which are respectively arranged at the two end surfaces of the roller 43. The limit plates 48 are rotatably connected to the rotating shaft 42. The distance between the two limit plates 48 is the same as the width of the paper. The limit setting of the two limit plates 48 prevents the paper between the two rollers 43 from shifting.

[0040] In this embodiment, the receiving assembly 30 includes a third support plate 31 and a receiving plate 32. The third support plates 31 are fixedly provided on both sides of the top of the output end of the work frame 10. Two receiving plates 32 are provided between the two third support plates 31. The two receiving plates 32 are arranged at intervals in the horizontal direction. Among them, the width of the roller 43 in the second guide member 40 is the same as the width of the two-layer state paper. When the two-layer state paper comes out of the steering mechanism 20 and enters the second guide member 40, the paper is moved to the receiving plate 32 through the transmission of the second guide member 40.

[0041] It is worth noting that the gap between the two receiving plates 32 is the heat sealing position. The third support plate 31 is provided with an escape groove 33, the position of which corresponds to the position between the two receiving plates 32, so as to facilitate the installation of the heat sealing structure and heat seal the paper.

[0042] The working principle of the utility model is as follows: when in use, the end of the paper is stretched out from the top of the rotating rod 12 and moved to the first guide member 40, so that the end of the paper passes between the two rollers 43, and the end of the paper is sent between the upper pressing plate 21 and the lower pressing plate 22 by the transmission force provided by the first guide member 40, so that the movable side of the single-layer paper passes through the upper lifting section 211, the folding section 212, the lower pressing section 213 and the gentle section 214 in sequence, so that the movable side is turned over to the upper side of the fixed side to form a two-layer paper; then the two-layer paper is moved and sent into the second guide member 40, and the transmission force provided by the second guide member 40 is used to move the two-layer paper to the receiving plate 32, so as to enter the subsequent heat sealing process; the paper continuously enters the upper pressing plate 21 and the lower pressing plate 22, so that the single-layer paper is continuously turned and turned to form a two-layer paper; finally, the paper after the heat sealing process becomes a U-shaped packaging bag connected together.

[0043] The beneficial effects of the utility model are as follows: the automatic turning machine provides a conveying force through the first guide member 40 for the paper to continuously enter between the upper pressing plate 21 and the lower pressing plate 22, so that the single-layer paper is turned and flipped to form a two-layer paper. Then, the conveying force provided by the second guide member 40 moves the two-layer paper to the receiving plate 32, which is convenient for the subsequent heat sealing process to heat seal the paper. Through the continuous turning and flipping process of the paper, manual operation is reduced and efficiency is improved.
