[0016] A method for using a conveying device for producing gypsum boards,

[0017] S1, start the conveyor belt to convey the gypsum board to one end, at this time the gypsum board is driven along the extension plate and the rolling roller to slide into the stacking seat, when the gypsum board moves into the stacking seat, the gypsum board presses down the stacking seat due to gravity;

[0018] S2, the stacking seat drives the control block to slide downward inside the track groove, and at the same time the control block pulls the steel cable to move along the track, and then the other end of the steel cable pulls up the connecting plate, and at the same time the hydraulic rod and the return spring are stretched, and the weight moves to the top of the sleeve;

[0019] S3. When the last gypsum board moves to the inside of the stacking seat, the control moves to the bottom of the track slot. At this time, the card strip is inserted into the inside of the card slot, and the servo motor is controlled to drive the drive shaft to rotate. At this time, the threaded drive slider drives the push block forward through the connecting strip to support the blocking block, so that it pushes the conveyor car to slowly leave the stacking seat.

[0020] S4. Then the insert block slowly slides out of the opposite side of the extrusion block. When the insert block completely falls off the extrusion block, the extrusion spring reacts on the extrusion block to make it close to each other. At the same time, the conveyor car takes the gypsum board completely off the stacking seat. Then the reset spring, hydraulic rod and weight react on the steel cable at the same time to pull the control block to drive the stacking seat to return to its initial position.

[0021] Beneficial effects:

[0022] Compared with the prior art, the conveying device and method for producing gypsum boards have the following beneficial effects:

[0023] 1. The present invention sets up an automatic stacking mechanism, which uses the gravity of the gypsum board to press down the stacking seat, so that it drives the control block to slide downward inside the track groove. At the same time, the control block pulls the steel cable to move along the same track, and then the other end of the steel cable pulls up the connecting plate. At the same time, the hydraulic rod and the return spring are stretched, and the weight moves to the top of the sleeve, which is conducive to the automatic transportation and stacking of the gypsum boards, reduces manual participation, and speeds up the transportation efficiency and improves safety.

[0024] 2. The present invention uses a pushing mechanism to drive the driving shaft to rotate using a servo motor. At this time, the threaded driving slider drives the pushing block forward through the connecting bar to press the blocking block, so that the conveying vehicle is pushed to slowly separate from the stacking seat, which is conducive to facilitating the separation of the stacked gypsum boards from the stacking seat, and avoids the operator being unable to push the conveying vehicle due to the huge friction between the gypsum boards and the stacking seat, thereby reducing work efficiency.

[0025] 3. The present invention provides an insert block and an extrusion block. When the insert block slowly slides out of the opposite side of the extrusion block, and when the insert block completely falls off the extrusion block, the extrusion spring reacts on the extrusion block to make it close to each other, which helps to ensure that the conveyor vehicle does not shake due to the influence of the on-site environment when waiting for the gypsum boards to be stacked, resulting in position deviation.

[0026] Other advantages, objectives and features of the present invention will be set forth in part in the following description and, in part, will be apparent to those skilled in the art based on an examination of the following or may be taught from the practice of the present invention.

[0037] The stacking seat 708 is pressed down by the gravity of the gypsum board 5, so that it drives the control block 709 to slide downward inside the track groove 12. At the same time, the control block 709 pulls the steel cable 705 to move along the same track. Then the other end of the steel cable 705 pulls up the connecting plate 704. At the same time, the hydraulic rod 702 and the return spring 703 are both stretched, and the weight 706 moves toward the top of the sleeve 701, which is conducive to the automatic transportation and stacking of the gypsum board 5, reduces manual participation, and at the same time speeds up the transportation efficiency and improves safety.

[0038] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the pushing mechanism 8 includes a servo motor 801, a driving shaft 802, a slider 803, a connecting bar 804 and a pushing block 805. The servo motor 801 is fixedly connected to the rear side of the base 6, and the output shaft of the servo motor 801 passes through the base 6 and is fixedly connected to the driving shaft 802. The slider 803 is movably connected to the outer side of the driving shaft 802 through a thread, and the connecting bar 804 is respectively fixedly connected to the upper and lower ends of the slider 803. The pushing block 805 is located directly in front of the driving shaft 802, and the pushing block 805 is fixedly connected to the opposite side of the connecting bar 804. The driving shaft 802, the slider 803, the connecting bar 804 and the pushing block 805 are all located at the bottom of the conveying vehicle 2.

The front end of the pushing block 805 is close to the blocking bar 9, and the rear ends of the blocking bar 9 are fixedly connected with the plug blocks 15.

[0039] The driving shaft 802 is driven to rotate by the servo motor 801, and at this time, the threaded driving slider 803 drives the pushing block 805 forward through the connecting strip 804 to press the blocking block, so that it pushes the conveying vehicle 2 to slowly separate from the stacking seat 708, which is conducive to facilitating the separation of the stacked gypsum boards 5 from the stacking seat 708, and avoids the operator from being unable to push the conveying vehicle 2 due to the huge friction between the gypsum boards 5 and the stacking seat 708, thereby reducing work efficiency.

[0040] like Figure 6 As shown, a group of left-right symmetrical fixing columns 16 are fixedly connected to the front end of the base 6, a rectangular groove 17 is opened at the front end of the fixing column 16, and the inner wall of the rectangular groove 17 is fixedly connected to a group of left-right symmetrical extrusion springs 18, the opposite sides of the extrusion springs 18 are fixedly connected with extrusion blocks 19, and the insertion blocks 15 are inserted on the opposite sides of the extrusion blocks 19.

[0042] Working principle: Start the conveyor belt 1 to convey the gypsum board 5 to one end. At this time, the gypsum board 5 is driven along the extension plate 3 and the rolling roller 4 to slide into the stacking seat 708. When the gypsum board 5 moves to the inside of the stacking seat 708, the gypsum board 5 presses down the stacking seat 708 by gravity, so that the stacking seat 708 drives the control block 709 to slide downward inside the track groove 12. At the same time, the control block 709 pulls the steel cable 705 to move along the same track, and then the other end of the steel cable 705 pulls up the connecting plate 704. At the same time, the hydraulic rod 702 and the return spring 703 are both stretched, and the weight 706 moves to the top of the sleeve 701. When the last gypsum board 5 moves to the inside of the stacking seat 708, the control moves to the bottom of the track groove 12. At this time, the card strip 13 is inserted into the inside of the card slot, and then the servo motor 801 is controlled to drive the driving shaft 802 to rotate. At this time, the threaded driving slider 803 drives the pushing block 805 forward through the connecting strip 804 to support the blocking block, so that it pushes the conveying vehicle 2 to slowly separate from the stacking seat 708, and then the plug block 15 slowly slides out of the opposite side of the extrusion block 19. When the plug block 15 completely falls off the extrusion block 19, the extrusion spring 18 reacts with the extrusion block 19 to make them close to each other. At the same time, the conveying vehicle 2 and the gypsum board 5 completely fall off the stacking seat 708, and then the reset spring 703, the hydraulic rod 702 and the weight 706 react with the steel cable 705 at the same time to pull the control block 709 to drive the stacking seat 708 to return to its initial position.
