Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, rather than all embodiments, and all other embodiments obtained by a person of ordinary skill in the art without creative efforts based on the embodiments of the present invention belong to the protection scope of the present invention.

The first embodiment is as follows:

as shown in figures 1 to 6:

products to be transported are conveyed into the cabin 1 through the material inlet 203, and when the inductive expansion door 206 in the material inlet 203 senses that an object approaches, the inductive expansion door contracts inwards to open a certain space in the cabin door 2 so as to convey the products into the cabin 1.

When the products enter the cabin 1 through the feeding port 203 and then fall on the storage device 3, the transmission main shaft 4 is driven to rotate by controlling the operation of the motor 112 to enable the storage device 3 meshed with the transmission main shaft to rotate, the products are transported to the storage device 3 at the bottommost part of the cabin 1 layer by layer, at the moment, an operator can see the transportation situation through the observation window 101, and the control terminal 111 is enabled to control the motor 112 to stop working after the products touch the touch button 115.

After the products are loaded, the inductive expansion door 206 is automatically closed to form a sealed environment inside the cabin 1, the environment inside the cabin 1 is transmitted to the control terminal 111 through the temperature sensor 113 and the humidity sensor 114, and the control terminal 111 controls the dry ice machine 108 to manufacture dry ice to match with the water in the water tank 117 according to the environment to generate low-temperature water mist, and the low-temperature water mist is transmitted into the cabin 1 to reduce the temperature and increase the humidity.

After the product arrives at the preset place, the motor 112 is controlled to work reversely, so that the storage belt 302 in the bottommost layer of the storage device 3 sends the product to the discharge hole 204, the telescopic transmission rod 202 is driven by the driving rotating shaft 301 to rotate and drive the film coating rotating shaft 208 to rotate to coat the film on the product, the product after film coating is finished is sealed by the plastic packaging device 209, and cold air and moisture are locked in the film coating package, so that the effect of prolonging the preservation time is achieved.

Example two:

as shown in fig. 12:

Example three:

as shown in fig. 7 to 11:

when the driving shaft 301 is driven by the driving shaft 4 to rotate, the driving teeth 305 on the surface of the driving shaft 301 will engage with the injection ports 310 on the inner side of the storage belt 302 and drive the storage belt 302 to rotate, so that the storage belt 302 will deliver the product to the storage belt 302 at the bottom of the cabin 1, and at the same time, the driving shaft 301 will conduct the cold air produced by the dry ice machine 108 to the inside of the driving shaft 301 by the fixing shaft 303 and guide the cold air into the storage belt 302 when the sealing baffle 307 is pushed open by the push rod 312 when the driving teeth 305 engage with the injection ports 310, and when the internal pressure of the storage belt 302 reaches a certain peak value, the cold air will be slowly discharged through the air outlet nozzle 308, so as to cool and humidify the inside of the cabin 1.

When vibration is generated during transportation, the connecting rod 317 on the surface of the bearing 304 contracts towards the inside of the bearing 304, meanwhile, the threads on the shaft of the connecting rod 317 drive the driving ring 315 to rotate, so that the connecting rods 317 in other directions contract inwards together, the diameter of the bearing 304 enables the storage device 3 to have a certain moving space to prevent the equipment from being damaged in the vibration, and meanwhile, the suction cups 318 are used for being adsorbed to the inner wall of the fixing groove 105 to place the storage device 3 in a deviation position.

The working principle is as follows: products to be transported are sent into the cabin body 1 through the material inlet 203, fall on the storage device 3 after entering the cabin body 1 through the material inlet 203, and after the products are loaded, the inductive telescopic door 206 is automatically closed to form a sealed environment inside the cabin body 1.

The transmission main shaft 4 is driven to rotate by the work of the control motor 112 to enable the storage device 3 meshed with the transmission main shaft to rotate, products are transported to the storage device 3 at the bottommost part of the cabin body 1 layer by layer, at the moment, an operator can clear the observation window 101 to observe the transportation condition, and the control terminal 111 is enabled to control the motor 112 to stop working after the products touch the touch button 115.

When the motor 112 rotates, the transmission main shaft 4 is engaged with the output end of the motor 112 by using the screw head at the bottom thereof to rotate, and is engaged with the driving rotating shaft 301 and the cold air output shaft 110 by using the engaging screw groove 402 on the shaft body of the transmission main shaft 4 to drive the same to rotate, and the cold air produced by the dry ice machine 108 is transmitted to the inside of the object placing belt 302 through the transmission main shaft 4 and the driving rotating shaft 301.

After the product arrives at a preset place, the control motor 112 works reversely to enable the storage belt 302 in the bottommost layer of the storage device 3 to convey the product to the discharge hole 204, at the moment, the telescopic transmission rod 202 is driven by the driving rotating shaft 301 to rotate and drive the film laminating rotating shaft 208 to rotate so as to carry out film laminating on the product, the product after film laminating is finished is subjected to edge sealing through the plastic packaging device 209, cold air and moisture are locked in the film laminating package, and the effect of prolonging the preservation time is achieved.
