[0002] Square bottom valve bags are a small bulk packaging container that is convenient, neat and has good sealing properties. They are widely used in the packaging of powdered and granular products such as chemical raw materials, new building materials, high-tech materials, pharmaceutical additives, food additives, starch, milk fat, engineering plastics, leaf paper bags, and pet food bags. After production, the square bottom valve bags need to be pressed, dried and hardened before packaging. Otherwise, the weak bag body is prone to wrinkles and deformation after packaging, so a hot air blower is needed to dry it.

[0003] According to a publicly disclosed hot air blower positioning device for producing square bottom valve bags (publication number: CN217686455U), in the above application, after the square bottom valve bags are sent into the interior of the drying box by a conveyor belt, the first hot air blower and the second hot air blower inhale and heat the outside air and then spray it into the interior of the first and second air diffuser boxes through pipes, and then the air is sprayed out from a plurality of outlet holes provided in the first and second air diffuser boxes to dry the square bottom valve bags.

[0004] However, during the actual use of the above equipment, the direction of the hot air blown out by the dryer remains fixed for a long time, and the square bottom valve bags entering the drying box along the conveyor belt have a certain depth and volume. During the drying operation, the hot air contact efficiency on the sides and bottom is not high, which leads to the overall low drying efficiency of the device. In view of this, we propose a hot air blower positioning device for the production of square bottom valve bags. Utility Model Content

[0010] Preferably, there are two groups of hot air blowers, blowing pipes, mounting seats and drainage mechanisms, and the two groups of hot air blowers, blowing pipes, mounting seats and drainage mechanisms are mirror-imaged on the upper and lower inner walls of the machine body, so that the square bottom valve bags entering the machine body can receive a more adequate drying processing effect.

[0011] Preferably, the bottom of the rotating drum is open, and the drainage belt is arranged on the inner surface of the bottom opening of the rotating drum.

[0012] Preferably, the diversion belt is arranged in a herringbone shape to enhance the device's effect of guiding and diverting hot air.

[0015] Compared with the prior art, the utility model provides a hot air blower positioning device for square bottom valve bag production, which has the following beneficial effects:

[0016] 1. The hot air blower positioning device for producing square bottom valve bags is provided with a drainage mechanism. When the hot air blower is started, the driving motor is started at the same time. In cooperation with the rotating cylinder with an open bottom, the hot air flow moving along the inner surface of the rotating cylinder will be affected by the drainage belt and the diversion belt and move in the horizontal direction at a certain speed, so that the hot air blown out from the rotating cylinder has a larger diffusion range and reduces the hot air speed in the vertical direction to a certain extent, thereby reducing the air convection when the hot air blowers are arranged on both the upper and lower sides of the machine body, and improving the drying efficiency of the device.

[0017] 2. The hot air blower positioning device for the production of square bottom valve bags is provided with a disturbance mechanism.

At this time, the magnetic rod intermittently repels the spoiler as the sleeve moves, causing the spoiler to rotate with the rotating rod as the rotation center. In conjunction with the volute spring, the spoiler continues to swing, thereby expanding the range of hot air blowing, thereby improving the drying efficiency of the device.

[0026] Furthermore, square openings are provided on the inner walls on the left and right sides of the machine body 1 to facilitate the square bottom valve bags to enter the machine body 1 for drying along with the conveying device 2, and to discharge the materials outward after drying. At the same time, the conveying device 2 includes a small motor, a transmission wheel, and a transmission belt provided on the arc-shaped outer wall of the transmission wheel, and a plurality of small holes are provided on the inner wall of the transmission belt to facilitate the circulation of hot air, so as to better dry the square bottom valve bags. In addition, the blowing pipe 4, the mounting seat 5 and the rotating cylinder 81 are arranged concentrically, and the arc-shaped outer surface of the arc-shaped block 7 is aligned with the outer surface of the blowing pipe 4. The surfaces are adapted to each other, so that when the fastening bolts 6 are tightened on the mounting base 5, the blowing pipe 4 can be positioned by the arc block 7 arranged on the inner side of the mounting base 5 to ensure the stable working state of the hot air blower 3.
