Because the buffer spring is arranged between the supporting table and the base, most of the vibration generated by the supporting table is absorbed by the buffer spring when the cylindrical shell is supported by the supporting table in the rolling process, and the supporting table can adaptively move along with the cylindrical shell under the action of the buffer spring, so that the cylindrical shell is always supported;
the supporting table effectively reduces the shaking possibly caused by uneven stress by arranging the guide rod matched with the guide groove on the base,
the stability of the shell ring in the rolling process is further improved under the cooperation of the shell ring and the shell ring.
The upper surface of the cushion block can be set to be a smooth cylindrical surface, so that friction and vibration generated by sliding of the cylindrical section on the surface of the cushion block in the rolling process can be effectively reduced, and the stability of the cylindrical section in the rolling process is better improved. Furthermore, the cushion block can also be made of elastic materials, so that the cushion block can be kept in surface contact with the inner surface of the cylinder section as much as possible, stress concentration of the cylinder section due to self weight and vibration is prevented, and structural stability of the cylinder section in the rolling process is ensured.
Preferably, the base is mounted below the slide by means of a vertically arranged lifting cylinder 7, which allows finer fine tuning of the radial position of the base.

Preferably, the buffer springs are arranged on two sides of the guide rod along the width direction of the saddle. This may make the pallet more stable to support and more evenly stressed. The spring has the advantages of low cost, durability, reliability and the like.
The working process of the utility model is as follows:
firstly, the lifting mechanism is adjusted to a proper position by driving the air cylinder, so that the distance between the outer side walls of the two brackets is approximately equal to the width of the cylinder section. Then, the lifting cylinder and the hydraulic cylinder are used for descending the base of the lifting mechanism to a slightly lower position, so that the cylinder section can be positioned above the supporting table when moving to a high position in rolling. Then, starting the veneer reeling machine, and gradually upwards rolling the cylindrical shell along the arc track. When the cylinder section is rolled to the upper part of the supporting table, the lifting cylinder and the hydraulic cylinder lift the base, so that the supporting table supports the cylinder section, and the height of the supporting table can be continuously adjusted at the moment so as to adapt to the diameter requirements of different cylinders.
