[0023] A plastic tray clamping device is characterized by comprising a frame body 1, two clamping plates 2 are arranged on one side of the frame body 1 in a sliding structure, the frame body 1 is provided with a power element 3 for driving the two clamping plates 2 to move away from or towards each other, the power element 3 is connected to the frame body 1, and clamping jaws 4 are arranged on the two sides of the clamping plates 2 to clamp and fix the waste edges, so that the waste edges in a softened state are prevented from being attached to the side wall of the plastic tray during the transfer process, subsequent cleaning is facilitated, the waste edge cutting efficiency is improved, and the product quality is ensured.

[0024] Specifically, the frame body 1 is connected to the clamping plate 2 through a linear guide rail 5, so that the clamping plate 2 can slide along the vertical direction.

[0025] It should be noted that the power element 3 is a cylinder, which is connected to the frame body 1 in a fixed structure, and the cylinder output shaft is connected to the clamping plate 2 to drive the two clamping plates 2 to clamp the plastic tray.

[0026] It should be noted that the inner end face of the clamping plate 2 is provided with a positioning core 6, which is inserted into the groove of the plastic tray during clamping, to ensure the stability of the clamping and transferring.

[0027] The positioning core 6 is provided in a circular truncated cone structure to solve the problem that the positioning core 6 cannot be inserted into the groove due to a certain error in the placement position of the plastic tray, and to ensure that the positioning core accurately enters the product groove.

[0028] Further, an adjusting mechanism for adjusting the movement of the clamping jaw 4 in the transverse and vertical directions is provided, and the adjusting mechanism is connected to the clamping plate 2 in a fixed structure.
