At present, the traditional paperboard stack conveying equipment usually has problems of inaccurate positioning and low conveying efficiency. These problems not only affect the production efficiency of the paperboard, but also may cause the product quality to decrease and increase the production cost. Therefore, how to realize the automatic conveying and accurate positioning of the paperboard stack has become a problem to be solved in the current paperboard production technical field.

In view of these problems, the application provides a conveying and positioning adjusting device for paperboard production, which aims to realize the automatic conveying and accurate positioning of the paperboard, and improve the production efficiency and product quality.

[0036] With reference to Figure 3 and Figure 4Further, the stabilizing rods 4 on the same side are connected by a connecting rod 41. The stabilizing rod 4 comprises a rod body 43 and an extension rod 44. The rod body 43 is provided with a receiving groove 431 along the length, and the receiving groove 431 is open towards the center line direction of the object table 31.

A plurality of support rods 51 are arrayed and vertically connected to the surface of the housings 311, with each support rod 51 corresponding to a stabilizing rod 4. On the side of the support rod 51 near the centerline of the platform 31, a plurality of first grooves 511 are formed along its length, and two drive sliders 512 are slidably connected in each first groove 511. A screw 513 is provided along the length of each first groove 511, and the screw 513 is rotatably connected to the support rod 51. The screw 513 passes through the two drive sliders 512, and the drive sliders 512 are threadedly connected to the screw 513. The screw 513 is a bidirectional screw 513, and the two drive sliders 512 are located at opposite ends of the screw 513. The cross-section of the first groove 511 is a polygonal structure, and the drive sliders 512 are polygonal structures corresponding to the cross-sectional shape of the first groove 511. When the screw 513 rotates, the threaded connection drives the sliders 512 to move closer or further apart radially along the screw 513. A motor 514, which drives the screw 513 to rotate, is installed inside the support rod 51.

[0040] Reference Figure 3 and Figure 4 The control component 5 includes a first link 52 and a second link 53.

The control component 5 also includes a plurality of first support rods 54 and a plurality of second support rods 55. One first support rod 54 and one second support rod 55 form a group. The middle of each first support rod 54 in each group is hinged to the corresponding second support rod 55, forming an X structure. And both ends of each first support rod 54 in each group are connected to the ends of the second support rods 55 in the adjacent group. The same applies to the second support rods 55 in each group. Thus, the plurality of first support rods 54 and the plurality of second support rods 55 form a continuous parallelogram structure. The ends of the first support rods 54 and the second support rods 55 furthest from the link are rotatably connected to driven sliders 56. A second groove 435 with a straight line is formed on the outer wall of the rod 43 along its length. The driven slider 56 is slidably connected to the second groove 435.

[0042] The implementation principle of a conveying and positioning adjustment device for paperboard production according to an embodiment of this application is as follows:

[0043] The tray 2 is placed on the moving path of the carrier 31, and the baffle 1 is moved to the appropriate position. The paperboard stack 6 is placed on the conveyor belt 321, and the carrier 31 is driven by the track structure to move to the baffle 1. After the carrier 31 moves to the baffle 1, the conveyor belt 321 starts and moves the paperboard stack 6 to abut against the baffle 1. The conveyor belt 321 continues to operate, and the paperboard stack 6 always has the tendency to abut against the baffle 1 under the action of the friction force of the conveyor belt 321. During the movement of the paperboard stack 6 driven by the conveyor belt 321, the conveyor belt 321 stops intermittently. At this time, the stabilizing rods 4 are pushed by the control assembly 5 and abut against the paperboard stack 6 from both sides to stabilize the structure of the paperboard stack 6. After the paperboard stack 6 abuts against the baffle 1, the stabilizing rods 4 continue to abut against the paperboard stack 6 from both ends, so as to keep the longitudinal structural stability of the paperboard stack 6 during the falling of the paperboard stack 6. The track drives the carrier 31 to move away from the baffle 1. During the movement of the carrier 31 away from the baffle 1, the paperboard falls on the tray 2 under the action of gravity. The subsequent forklift transfers the tray 2.

[0044] The above are preferred embodiments of the present application, which do not limit the protection scope of the present application. Any equivalent changes made on the basis of the structure, shape, and principle of the present application should be covered by the protection scope of the present application.
