[0019] The guard plates 11 are fixed to both sides of the front end of the lifting plate 10 through reinforcing seats 14, and a motor 17 for driving the rotating shaft 15 to rotate is fixed to the reinforcing seat 14 on the left side. The rotating shaft 15 drives the conveying chain 13 at the front end of the lifting plate 10 and the rear end of the guard plate 11 to rotate under the drive of the motor 17, so that the tooling plates 12 on the two sets of conveying chains 13 enter and exit the protective frame 1.

[0020] The rotating shaft 15 has second sprockets 19 fixed at both ends and passes through the lifting plate 10 and the guard plate 11 , and the front end of the lifting plate 10 and the rear end of the guard plate 11 are also movably connected to the third sprocket 20 , and the conveying chain 13 is connected between the corresponding second sprocket 19 and the third sprocket 20 .

[0021] A fourth sprocket 18 is also fixed on the rotating shaft 15 , and the fourth sprocket 18 is connected to a fifth sprocket 22 fixed at the output end of the motor 17 through a second chain 21 .

[0022] The lifting conveyor includes a lift and a conveying platform;

[0023] The lift includes a cylinder 4, a lift seat 6, a first chain 2 and a sliding mechanism; the conveying platform includes a lift plate 10, a reinforcement seat 14 and a guard plate 11;

[0024] The lift drives the lifting seat 6 to move up and down through the cylinder 4, and the up and down movement of the conveying platform is ensured by the driving of the first chain 2 and the control of the sliding mechanism.

[0025] The conveying chain 13 of the conveying platform is driven by the power of the motor 17 and can run forward and reverse, that is, enter and exit.

[0026] Specifically, when in use, the tooling plate 12 is driven into the conveying platform through the conveying chain 13; the motor 17 drives the second chain 21 to rotate forwardly, and since the fourth sprocket 18 is also fixed on the rotating shaft 15, and the fourth sprocket 18 is connected to the fifth sprocket 22 fixed at the output end of the motor 17 through the second chain 21, the second chain 21 rotates forwardly to drive the rotating shaft 15 to rotate forwardly;

When the lifting seat 6 rises, the conveying platform is driven to move upward smoothly;

[0030] The tooling plate 12 is driven to output the conveying platform through the conveying chain 13. Subsequently, the motor 17 drives the second chain 21 to reverse, and the second chain 21 rotates forward to drive the rotating shaft 15 to rotate backward, and the rotating shaft 15 rotates backward to drive the front and rear conveying chains 13 to rotate backward, so that the tooling plate 12 is moved out from the right side of the protective frame 1.
