[0032] The working principle of the present utility model is as follows:

[0033] The operator can place the device at the discharge port of the shelling machine, and the shells processed by the shelling machine can directly enter the top of the platform 1 in the device from the discharge port of the shelling machine. Start the motor 19, and the conveyor roller 6 can rotate under the drive of the first belt 17 and the second belt 21, so as to convey the shells to the bottom of the gantry 7; after turning off the motor 19, turn on the cylinder 8, and the piston rod of the cylinder 8 drives the bearing plate 9 to move vertically downward. Since the bottom surfaces of the two auxiliary pressure blocks 11 are lower than the bottom surface of the main pressure block 10, the bottom surfaces of the auxiliary pressure blocks 11 first contact the shells, thereby pre-flattening both sides of the shells. As the piston rod of the cylinder 8 moves, the inner inclined surface of the auxiliary pressure block 11 slides along the outer inclined surface of the main pressure block 10, so that the bottom surface of the main pressure block 10 contacts the shells, and the main pressure block 10 and the auxiliary pressure blocks 11 flatten the shells together; during the shell flattening process, the hydraulic cylinder 4 can effectively support the supporting platform 3. After the flattening operation is completed, the piston rod of the cylinder 8 will drive the main pressure block 10 and the auxiliary pressure block 11 to move vertically upward, and the piston rod of the hydraulic cylinder 4 will lift the supporting platform 3 upward, so that the upper surface of the supporting platform 3 is higher than the upper surface of the base 1, and the motor 19 is started to transport the flattened skin shell to the rear of the device. The operator can place the transfer box on the rear side of the device to realize the storage and processing of the flattened skin shell.

[0034] The above description of the disclosed embodiments will enable one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
