[0014] In order to further understand the purpose, structure, characteristics and functions of the present utility model, the following is a detailed description in conjunction with the embodiments.

[0015] Please refer to Figure 1 , a bag smoothing device with an inverted triangle structure, including a back plate 1 and a rotating plate 2; the rotating plates 2 are symmetrically arranged on both sides of the back plate 1; the two ends of the rotating plate 2 are respectively provided with a first rotating device 21 and a second rotating device 22; the back plate 1 and the rotating plate 2 are rotatably connected through the first rotating device 21; a rotating table 3 is further provided below the second rotating device 22; the rotating table 3 and the second rotating device 22 are rotatably connected; an ear plate 4 is further provided below the rotating table 3; the ear plate 4 is fixedly arranged in the middle of the rotating table 3.

[0016] When the inverted triangle structure is in use, it can effectively gather the packaging bags and avoid the situation that the packaging bags are stacked on the conveyor belt. By adjusting the angles of the first rotating device 21 and the second rotating device 22 to control the ear plate 4, the packaging bags passing through the bag smoothing device can be kept flat and will not fall over, greatly improving the production efficiency.

[0017] Preferably, a trapezoidal flattening pad 41 is further provided at the bottom of the ear plate 4; the flattening pad 41 is detachably installed at the bottom of the ear plate 4.

[0018] The flattening pad 41 is made of sponge with a relatively soft material. It will not scratch or damage the surface of the packaging bag. At the same time, the sponge has a certain adhesiveness to the packaging bag and can play an auxiliary stabilizing effect during use. Moreover, the price of the sponge is relatively cheap, and it does not require too much additional expenditure to replace it when it is damaged, saving the production cost.

[0019] Preferably, a control device 5 is further provided on the back plate 1; a driving device 6 is provided inside the rotating plate 2; the control device 5 is electrically connected to the driving device 6 in terms of electrical signals.

[0020] Preferably, the driving device 6 is electrically connected to the first rotating device 21 and the second rotating device 22 respectively in terms of electrical signals.

[0021] Preferably, the rotation angle of the first rotating device 21 is between 90° and 180°; the rotation angle of the second rotating device 22 is between 45° and 90°.

[0022] The rotation angle of the first rotating device 21 is between 90° and 180°. By restricting the rotation range, the stability of the system can be improved; restricting the angle can reduce the risk of collision; the rotation angle of the second rotating device 22 is between 45° and 90°. By means of a smaller rotation range, the design and operation of the control system can be simplified. When in use, only less movement range needs to be concerned about, so the system can be more easily controlled and adjusted.

[0023] Preferably, the width of the back plate 1 is greater than the sum of the widths of the rotating plates 2.

[0024] Avoid that in case of misoperation, the rotating plates 2 will collide with each other, resulting in damage to the device.

[0025] Specific implementation:

[0026] When in use, according to the size of the packaging bags on the conveyor belt, the control command is sent to the control device 5 through the background device. After the control device 5 receives the control command, it sends a driving signal command to the driving device 6 to adjust the angles of the first rotating device 21 and the second rotating device 22; so as to facilitate the packaging bags to remain flat and not fall down after passing through the device along the conveyor belt, thereby achieving the purpose of stretching the packaging bags.

[0027] The present utility model has been described by the above related embodiments. However, the above embodiments are only examples for implementing the present utility model. It must be pointed out that the disclosed embodiments do not limit the scope of the present utility model. On the contrary, any changes and modifications made without departing from the spirit and scope of the present utility model fall within the scope of the patent protection of the present utility model.
