Abstract
Description
Technical Field
[0001] The present application relates to the field of air curtain technology, and in particular to an air curtain for a cabin door of a freezing trimmer. Background Art
[0002] The freezing trimming machine uses the low-temperature freezing effect of liquid nitrogen to embrittle the products of rubber, plastic or zinc-magnesium-aluminum alloy, and sprays polymer particles at high speed to hit the burrs of the products, thereby removing the burrs with high efficiency and high precision.
[0003] Rubber and plastic materials are all polymer materials, and they will be in different phases at different temperatures. From the perspective of phase state, the material is only a change in mechanical state. When the material is under low temperature conditions, the state changes. When it returns to normal temperature conditions, the various properties will be restored. The freezing trimming machine uses the low-temperature freezing effect of liquid nitrogen to embrittle rubber and plastic materials. At this time, the burrs are embrittled before the product. In the time difference between the burrs being embrittled and the product not being embrittled, a high-molecular particle is sprayed at high speed to impact the burrs of the product to remove the burrs of rubber and plastic products and aluminum and zinc alloy products with high quality.
[0004] After the existing freezing trimming machine completes processing of the product, it is necessary to flip the drum out of the box to take out the processed product. Since the temperature inside the box is very low after being cooled by liquid nitrogen, when the external air enters the box, the water vapor in the air will condense in a short time, which may block the discharge port of the sprayed polymer particles, and there is a risk that the particles cannot be sprayed out during the next product processing. Utility Model Content
[0005] In order to reduce the probability risk of external moisture entering the box and condensing to block the molecular discharge port, the present application provides an air curtain for the door of a freezing trimming machine.

Therefore, when the two air curtain devices are working at the same time, the problem of the air curtain generated by a single air curtain device being blocked by the roller and the external air entering the case from the other side of the roller relative to the air curtain device is avoided, which further ensures the effect of the air curtain device in reducing the exchange of internal and external air.
[0023] In summary, the present application includes at least one of the following beneficial technical effects:
[0024] 1. Use the guide box to guide the wind blown out by the air curtain machine, so as to form a wind wall at the door of the freezing trimming machine, reduce the frequency of air flow inside and outside, and thus reduce the probability of water vapor condensation blocking the particle discharge port due to the low temperature inside the box after the external air enters the box, and interfere with the possibility of particle ejection during the next trimming process of the freezing trimming machine;
[0025] 2. Since the control structure is electrically connected to the air curtain machine, the control structure can automatically control the switch of the air curtain machine instead of the staff manually switching the air curtain machine. On the one hand, it can improve the instantaneity of the air curtain machine switch, and on the other hand, it can prevent the staff from close contact with the freezing trimmer to prevent frostbite;
[0026] 3. When the frozen trimmer is loading and unloading, the roller passes through the door of the frozen trimmer, and the roller will hinder the air curtain formed by the air curtain device at one end. Therefore, when the two air curtain devices are working at the same time, the air curtain generated by a single air curtain device is avoided from being blocked by the roller, and the external air enters the box from the other side of the roller relative to the air curtain device, which further ensures the effect of the air curtain device in reducing the exchange of internal and external air.
