AI Technical Summary
In existing technologies, the cut plastic sheets are prone to tilting during the material dropping process, resulting in uneven stacking on the ground and increasing the difficulty for workers to organize them.
A guide and limiting component, including a carrier plate and a drive kit, is set at the end of the conveyor belt. The carrier plate is driven to rotate by the drive kit, which guides and limits the falling speed and direction of the plastic plate, so that it falls slowly and flat onto the receiving platform.
This allows for the flat stacking of plastic sheets, reducing the difficulty of handling by workers and improving the convenience and efficiency of the material unloading process.

[0042] Referring to Figure 1 and Figure 3, the guide limiting assembly 3 is composed of two bearing plates 31 and a driving sleeve 32, the two bearing plates 31 are oppositely arranged at the two ends of the length direction of the mounting rack 1, the bottom end of the bearing plate 31 is welded and fixed with a rotating shaft 34, the bearing plate 31 rotates on the mounting rack 1 through the rotating shaft 34, and the two bearing plates 31 are oppositely arranged, in the initial state, the two bearing plates 31 are located in the same horizontal plane, at this time, the two bearing plates 31 are spliced to form a bearing platform, the bearing platform is located above the receiving platform 2, and the bearing platform is used for receiving the plastic plates conveyed at the end of the conveying belt.
[0043] With reference to Figure 3 and Figure 4 , in use, when the plastic plates on the conveying belt are conveyed to the bearing platform, the two bearing plates 31 can be driven to rotate synchronously to open through the driving sleeve 32, at this time, the guide space 33 is formed between the two bearing plates 31, the guide space 33 is used for guiding and limiting the falling of the plastic plates, that is, in the process of the bearing plate 31 rotating and tilting, the plastic plates fall along with it and always abut against the upper surface of the bearing plate 31, so that the bearing plate 31 plays a role in guiding and limiting the falling direction and falling speed of the plastic plates, until the bearing plate 31 rotates to a specified angle, the bearing plate 31 falls to the receiving platform 2 through the guide space 33, so as to realize the purpose of ensuring the stability and flatness of the falling process of the plastic plates.

At this time, the return spring 43 is in a compressed state. After the staff releases the positioning pin 42, the positioning pin 42 returns to the original position under the action of the return spring 43. Then the receiving platform 2 can be slid. When the receiving platform 2 is slid to the one end close to the positioning pin 42, the staff pulls the positioning pin 42 to compress the return spring 43, and then moves the receiving platform 2.
