Description

Technical Field

[0001] This application relates to the technical field of plastic trays, and particularly to a feeding device for plastic trays. Background Art

[0002] Plastic trays, also known as plastic inner trays, are made of plastic hard sheets through a thermoforming process into plastics with specific grooves. The products are placed in the grooves to play a role in protecting and beautifying the products. There are also transportation-type tray packages, and most of the trays are used for convenience.

[0003] The existing Chinese patent with the publication number CN216104209U discloses an automatic feeding device for plastic trays, including: a base; a processing frame fixed on the top of the base; a box body fixed on the top of the inner wall of the processing frame, and a lead screw is rotatably connected between two sides inside the box body. Two threaded plates are threadedly connected to the outer surface of the lead screw, and both of the two threaded plates are slidably connected to both sides inside the box body. The automatic feeding device for plastic trays provided by the present utility model can limit and guide the plastic trays placed on the conveyor belt through the arranged two rows of guide wheels, avoiding a large accumulation of plastic trays on the conveyor belt when the feeding amount is large, resulting in too dense contact between adjacent plastic trays, making it impossible for the operator to see whether the surface of the plastic tray is deformed, thus facilitating the inspection of the surface of the plastic tray and ensuring the normal and stable operation of subsequent processes, thereby improving the practicability of the device.

[0004] However, the above feeding device has the following disadvantages: The device limits the plastic trays through the arranged guide wheels, but the guide wheels of the device cannot adjust the height according to the height of the trays to ensure that the guide wheels are in the middle of the plastic trays, which easily limits the bottom of the plastic trays but not the top, resulting in the deformation of the plastic trays. At the same time, since the guide wheels cannot buffer outward according to the pressure of the plastic trays after approaching the plastic trays, it is more likely to cause the deformation of the trays, and personnel need to pay attention to it and make adjustments later.

[0005] Therefore, we propose a feeding device for plastic trays to solve this problem.

[0006] The above information disclosed in this background art is only used to increase the understanding of the background art of this application. Therefore, it may include prior art that is not known to those of ordinary skill in the art. Summary of the Utility Model
