The terminology used in the description of the present application herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the present application. As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items.

[0027] As shown in Figures 1 to 3 , Figure 11 The present application provides a simple operation type airflow puffing machine, which comprises a rack, a tank cover 21, a tank body 20, a locking bent bow 2, a lock hook 19, an uncovering fork rod 5, an uncovering cylinder, a tank cover and tank body overturning mechanism; the locking bent bow 2 is provided with a tank cover 22, the locking bent bow 2 is provided with a lock hook 16, the locking bent bow 2 and the lock hook 19 are respectively pinned to the tank body 20, the end of the lock hook 19 is provided with the uncovering fork rod 5, the uncovering fork rod 5 is connected with the uncovering cylinder, the overturning shaft of the tank cover and tank body overturning mechanism is arranged on the tank cover 21, the end of the labor-saving lever 1 is fixedly connected with the oval-shaped handle, the labor-saving lever 1 is convenient to operate, the overturning shaft is rotated by pushing and pulling the labor-saving lever 1, and the tank cover 21 and the tank body 20 are overturned together, so that the feeding and discharging are realized.

[0028] The rack on the left and right sides of the tank cover 21 is respectively provided with a tank cover damping mechanism 4, and the rack below the locking bent bow is provided with a bent bow damping mechanism 3; the damping mechanisms are all composed of metal springs and elastic rubber or plastic; the bent bow damping mechanism 3 is controlled by a cylinder and can be extended and retracted back and forth; the bent bow needs to be popped open during puffing, and the damping mechanism stops at the position where the bent bow is popped open; when it is not needed, it is retracted to the front of the rack, so that the tank cover and the tank body are overturned to feed and discharge.

[0029] As shown in Figure 5 , Figure 6As shown, the outer layer of the arch damping mechanism is a protective layer 6, which is made of a metal plate or steel wire, fiber reinforced rubber or carbon fiber composite plate with certain strength, the middle layer is elastic rubber or plastic, and the inner layer is an upper and lower split cavity structure. The outer layer, the middle layer and the inner layer of the arch damping mechanism are connected by a guide connecting rod, a metal spring 10 is sleeved on the guide connecting rod, the upper end of the metal spring 10 is limited by the upper cavity 8 of the inner layer, and the lower end of the metal spring 10 is limited by the bottom of the spring sleeve. The spring sleeve is fixed on the lower cavity of the inner layer (a spring sleeve is additionally arranged in the lower cavity 11 of the inner layer for limiting the lower end of the spring. When there is no spring sleeve, the lower cavity 11 of the inner layer can directly limit the lower end of the spring, as shown in Figure 7 ), and elastic rubber or plastic is placed inside the lower cavity of the inner layer. Among them, the outer layer, the middle layer and the upper cavity of the inner layer are tightly attached, and a certain gap is left between the upper cavity of the inner layer and the elastic rubber or plastic on the lower cavity of the inner layer. There can also be no gap, but the damping effect is better when there is a gap.

[0030] It should be noted that the elastic rubber can be square or circular, and the shape is more stable when there is a protective layer on the surface of the elastic rubber, which is the optimal solution. The metal spring can be one, and the effect is better when it is optimized to two. The elastic rubber can be arranged between the two metal springs, or one piece can be arranged on the left and right outermost sides of the two metal springs, or three pieces can be arranged as shown in Figure 5 .

[0031] As shown in Figure 8 , Figure 9 , the tank cover damping mechanism includes a sliding block 17, and the turning shaft 12 of the tank cover body turning mechanism passes through the center hole of the sliding block 17 and is connected with the sliding block. A tank cover up-down turning positioning hole 18 is also arranged beside the center hole of the sliding block. Metal springs are arranged horizontally in front of and behind the sliding block 17, and the metal springs are sleeved on spring guide shafts. The front end of the rear metal spring 14 is provided with elastic rubber 15 and rubber protective plate 16.

[0032] It should be noted that the metal spring in front of the sliding block 17 can be removed, which can also achieve the damping effect.

[0033] As shown in Figure 10 , in this embodiment, the uncovering fork rod has a U-shaped structure, and a roller and a shaft sleeve are arranged at the middle position of the U-shaped structure. When the uncovering cylinder pushes the uncovering fork rod, it is more labor-saving. It should be noted that the roller and the shaft sleeve in the figure can also be removed to achieve deviation correction.

[0034] When the set pressure is reached, the PLC informs the uncovering cylinder to execute the action, pushes the uncovering fork rod to push the lock hook, the lock hook loses the locking force of the arch, the arch and the tank cover connected with the arch are instantaneously opened, the material in the tank body instantaneously loses pressure and expands, and at the same time, the arch damping mechanism 3 is controlled by the cylinder, and the arch damping mechanism stops at the arch opening position, as shown in Figure 4 .
