The difference between the production method of the thermoforming container mold jacket online machine in the embodiment and the production method of the thermoforming container mold jacket online machine in the embodiment 1 is that when a paper cup jacket machine breaks down or is decelerated accidentally, the central controller designates to start the standby machine, meanwhile, the sheet machine reduces the temperature and slows down the discharging speed, the plastic container part produced by the air pressure thermoforming machine is temporarily stored in the storage bin, the temperature control cooling system continues to detect the temperature and adjusts the air volume of the air cooler under the instruction of the central controller so as to adjust the pipeline conveying speed, and the air outlet temperature of the air cooler is adjusted to ensure that the discharging temperature of the plastic container is stable and consistent.

Example 4

The main technical solution of this embodiment is substantially the same as that of embodiment 1 or embodiment 2, and the features that are not explained in this embodiment adopt the explanations in embodiment 1 or embodiment 2, which are not described herein again. This example differs from the in-line production method of thermoformed container mold jacket of example 1 in that step 3.1 can be broken down into the following major sub-steps,

3.1.1 the robot 21 will transfer to the carrier 22-1 of the white cup transfer device 2;

3.1.2 the turnover driving device drives the second rotating shaft 22-4 to rotate, the second rotating shaft 22-4 drives the rotating base 22-3 to rotate, the rotating base 22-3 drives the first rotating shaft 22-2 and the bracket 22-1 to rotate downwards, and the collision block 22-7 collides with the limiting piece 22-8 to enable the bracket 22-1 to turn over and unload materials towards the side edge;

3.1.3 the plastic containers fall into a storage device, and the strip-formed plastic containers on a discharge conveying channel 22-11 of the storage device are conveyed to a cooling conveying mechanism 23 step by a conveyor 22-12;

3.1.4 when the conveyor 22-12 is conveying the plastic containers in strips stepwise to the cooling conveyor 23, the plastic containers pass through the baffle plates 22-13 one by one, the opening edge of the foremost plastic container is positioned outside the baffle plate 22-13 and is easily sucked away by the cooling conveyor 23 under negative pressure, and the rest plastic containers are positioned in the baffle plates 22-13 and are separated from the foremost plastic container.

The method has the advantages of compact and reasonable steps, smooth action and high efficiency.

Finally, it should be noted that the above embodiments are only used for illustrating the technical solutions of the present invention and do not limit the protection scope of the claims. It will be understood by those skilled in the art that various modifications and equivalents may be made to the embodiments of the present invention without departing from the spirit and scope of the invention.
