Description

Technical Field

[0001] The present application relates to the technical field of packaging machines, and specifically to a tray packaging machine. Background Art

[0002] A packaging machine is a machine that wraps products for protection and aesthetics. Packaging machines are primarily categorized into two types: 1. Assembly-line packaging for complete production, and 2. Equipment for peripheral packaging of products. Pallet wrapping machines are high-quality, compact yet robust machines equipped with various features tailored to specific needs, such as wrapping large pallets, particularly heavy goods, and unstable, lightweight pallets.

[0003] Patent No. CN221718894U discloses a pallet wrapping packaging machine. The pallet wrapping packaging machine uses a fixed component structure to clamp and fix the product pallet during use, allowing subsequent packaging to slide and shift. The fixed plate is symmetrically fastened to the rotating pallet to prevent it from falling off during use. When in use, the clamping plate is bent to both sides, and then the stacked foam end cap pallet is placed on the rotating pallet. The clamping plate is then released. Under the elastic action of the return spring, the clamping plate clamps the pallet to fix it. During clamping, the rubber soft plate on the front end surface of the clamping plate, on the one hand, makes it clamped more tightly and not easy to loosen, and on the other hand, the soft properties of the rubber can prevent the pallet from being damaged. So that the product will not slide and shift during subsequent packaging, ensuring its stability and enabling subsequent packaging to be completed smoothly. However, the movable component of the packaging machine can only clamp the wrapping film of a fixed width and cannot be replaced with wrapping film of other lengths. This limits the scope of use of the packaging machine and reduces the cost-effectiveness of the pallet wrapping machine. Utility Model Content
