[0028] Please refer to Figures 1-3 , a front-back connected lifting conveyor device in this embodiment includes:

[0029] Two sets of conveying frames 1, screw rods 2 are rotatably connected to the inner sides of the two sets of conveying frames 1. A stepping motor is fixedly connected to the top of the conveying frame 1, and the end of the rotor of the stepping motor is fixedly connected to the screw rod 2 coaxially. A moving block 3 is threadedly connected to the outside of the screw rod 2. One side of the moving block 3 is fixedly connected to a fixing plate 4. Above the fixing plate 4 is provided a feeding frame 5. There is a certain height difference between the two sets of conveying frames 1, and the two sets of conveying frames 1 are fixedly connected by a connecting frame. Guide rods are fixedly connected to both sides of the screw rod 2 and are slidably connected to the moving block 3, which can play a guiding role in the vertical movement of the moving block 3. The cross-sectional area of the lower feeding frame 5 is smaller than the cross-sectional area of the upper feeding frame 5, which can prevent materials from spilling when entering the upper feeding frame 5 from the lower feeding frame 5;

[0030] An automatic discharging component, which includes strip-shaped grooves symmetrically opened on both sides of the feeding frame 5. A vertical rod 101 is fixedly connected to the inside of the strip-shaped groove. A slider 102 is slidably connected to the outside of the vertical rod 101. A first spring 103 is sleeved on the outside of the vertical rod 101, and both ends of the first spring 103 are fixedly connected to the slider 102 and the inner wall of the strip-shaped groove respectively. A baffle 104 is rotatably connected to one side of the feeding frame 5. A first connecting rod 105 is hinged between the baffle 104 and the slider 102. A connecting column 106 is fixedly connected to the top of the slider 102. A limiting plate 107 is fixedly connected to the top of the conveying frame 1. The area of the baffle 104 is consistent with the cross-sectional area of the side profile of the feeding frame 5 to which it is hinged, which can prevent materials from leaking out during lifting and conveying;

[0031] An automatic opening and closing component, which includes cross bars 201 symmetrically fixedly connected to the top of the fixing plate 4. Movable blocks 202 are symmetrically slidably connected to the outside of the cross bars 201. A second connecting rod 203 is hinged between the movable blocks 202 and the feeding frame 5 through hinge parts. Second springs 204 are symmetrically sleeved on the outside of the cross bars 201.

[0032] The automatic opening and closing component further includes:

[0033] A fixed bracket, which is fixedly connected to the top of the moving block 3. A second touch switch 205 is fixedly connected to the fixed bracket. A first touch switch 206 is arranged directly below the second touch switch 205 and is fixedly connected to the moving block 3. A touch rod 207 is arranged between the second touch switch 205 and the first touch switch 206, and the touch rod 207 is fixedly connected to the feeding frame 5.

[0034] A signal transmitter, which is fixedly connected to one side of the fixed bracket. A signal receiver is fixedly connected to one side of the stepping motor. A controller is fixedly connected to one side of the signal receiver.

[0035] In the embodiment of the present application, the implementation principle of the front-back connected lifting and conveying device is as follows: The material is loaded into the lower feeding frame 5. Due to the increase in the overall weight of the feeding frame 5, and under the sliding fit between the movable block 202 and the cross bar 201, and the hinged fit among the movable block 202, the feeding frame 5, and the second connecting rod 203, the movable block 202 will slide towards both sides of the cross bar 201 and compress the second spring 204. At this time, the feeding frame 5 will move vertically downward. The downward movement of the feeding frame 5 drives the touch rod 207 to move downward. When the touch rod 207 contacts the first touch switch 206, it will control the signal transmitter to send a signal. The model of the signal generator is Rigol DG1022. When the signal receiver receives the signal, the controller will control the stepping motor to rotate forward, thereby driving the screw rod 2 to rotate. The model of the signal receiver is SHF, and the model of the stepping motor is 35BYJ-46. The stepping motor can control the screw rod 2 to stop after rotating a certain number of turns. The rotation of the screw rod 2 drives the moving block 3 to move upward, and the upward movement of the moving block 3 can drive the feeding frame 5 on the fixed plate 4 to move upward together. When the connecting column 106 contacts the limiting plate 107, due to the obstruction, the slider 102 will slide outside the vertical rod 101 and compress the first spring 103. And by using the hinged action between the slider 102 and the baffle 104 and the first connecting rod 105, and the rotational fit between the baffle 104 and the feeding frame 5, it is possible to push the baffle 104 to deflect, so as to facilitate the discharge of sheet-shaped or block-shaped materials therein. After the materials are discharged, the overall weight will be reduced. Using the resilience of the second spring 204, the feeding frame 5 will automatically reset, and the touch rod 207 will also contact the second touch switch 205. At this time, the signal transmitter will emit a signal that is received by the signal receiver, and the controller will control the stepping motor to rotate in reverse. The controller is a PLC controller. At this time, the feeding frame 5 will automatically reset. At the same time, the discharged materials will enter another feeding frame 5. Using the above principle, the continuous lifting and conveying of the materials can be realized.

[0036] Embodiment 2:

[0037] On the basis of Embodiment 1, the further improvement of this embodiment lies in that the bottom of the inner cavity of the feeding frame 5 is inclined, which can not only accelerate the discharge of materials, but also prevent the materials from remaining.

[0038] The above implementation manners are only the preferred implementation manners of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by those skilled in the art on the basis of the present invention fall within the protection scope required by the present invention.
