TECHNICAL FIELD
[0001] The utility model relates to food, feed processing equipment field, concretely relates to a durable airflow puffing machine. BACKGROUND
[0002] Large airflow puffing machine is a kind of grain puffing equipment, which is composed of puffing tank body, heating device, rotating device, safety protection device, damping device, rack and base etc.Its working principle is that certain material is loaded into the sealed cast steel tank body with cover, and is heated by using liquefied gas, coal gas or coal, and the tank body is continuously rotated at a certain speed, so that the material is uniformly heated, and the temperature in the tank gradually rises with continuous heating, and the water in the material body surface and body will escape and vaporize, forming a certain pressure in the tank.When the water content of the material is controlled to about 5% to 12%, the pressure in the tank will reach 0.2 to 1.3 Mpa (different materials have different pressures).At this time, the material in the tank has been basically cooked, and if the tank cover is suddenly opened, the material will be dehydrated and expanded, and its structure will change, and the volume will expand several times to tens of times.
[0003] The existing airflow puffing machine has the following disadvantages: when the cover is opened, the tank cover and the tank body rely on two groups of springs for damping, and the damping effect is not good, and the rack and the bow are easy to deform and break. SUMMARY
[0004] The utility model discloses a durable airflow puffing machine, which can effectively reduce the damage of the vibration force generated by instantaneous puffing to the machine and significantly improve the service life of the machine.
[0005] The utility model discloses a durable airflow puffing machine, which can effectively reduce the damage of the vibration force generated by instantaneous puffing to the machine and significantly improve the service life of the machine.
[0006] In this invention, both the tank cover shock absorption mechanism and the bow shock absorption mechanism are composed of a combination of metal springs and elastic rubber or plastic. Metal springs are durable, but their excessive rebound force and elasticity make them prone to deformation, easily damaging the machinery due to spring-induced vibrations. Furthermore, the relative positions of parts can easily change, preventing certain mechanical actions from being completed. Elastic rubber and plastic, on the other hand, offer stable shape and excellent shock absorption. The combination of these two materials allows the metal spring to absorb the initial impact force, while the rubber and plastic assist in absorbing subsequent impact forces, maintaining shape and stable relative positions of the parts. Alternatively, the rubber and plastic can absorb the initial impact force, while the metal spring absorbs the later impact force; this type of shock absorption mechanism achieves the same effect.
[0007] In the above technical solution, the outer layer of the bow shock absorption mechanism is a protective layer, which is made of metal plate or steel wire, fiber-reinforced rubber or carbon fiber composite plate with a certain strength. The middle layer is elastic rubber or plastic, and the inner layer is a split cavity structure. The outer, middle and inner layers of the bow shock absorption mechanism are connected by a guide connecting rod. A metal spring is sleeved on the guide connecting rod. The upper end of the metal spring is restricted by the protective layer or the upper cavity of the inner layer, and the lower end of the metal spring is restricted by the spring outer sleeve or the lower cavity of the inner layer. The spring outer sleeve is fixed on the lower cavity of the inner layer, and elastic rubber or plastic is placed inside the lower cavity of the inner layer.
[0008] In the above technical solution, the tank cover shock absorption mechanism includes a slider, a metal spring is horizontally arranged behind the slider, and an elastic rubber is provided on the side of the metal spring. The elastic rubber is placed inside a rubber guide protective sleeve.
[0009] In the above technical solution, the opening fork has a U-shaped structure for positioning and correcting the end of the locking hook when opening the cover.
[0010] This utility model of a durable airflow extruder has a simple structure and is easy to use. It can effectively reduce the damage to the machine caused by the vibration force generated during instantaneous extrusion and significantly improve the service life of the machine.

[0023] Tank cover damping mechanism 4 and bent bow damping mechanism 3 in the utility model are all made of metal spring and elastic rubber or plastic combination, metal spring is durable, but rebound force and telescopic property are too big, and it is also easy to be deformed, and the relative position of parts is easy to change, leading to the failure of some actions of machine;And elastic rubber, plastic shape is stable, also have good impact shock absorbing force;Metal spring absorbs the impact force in early stage, and rubber plastic then assists to absorb the impact force in subsequent stage, and keeps shape and relative position of parts stable.
