Description

Technical Field

[0001] This utility model relates to the field of packaging machine technology, and more specifically, to a servo top box device for a transparent three-dimensional film packaging machine. Background Technology

[0002] Heat shrink film packaging machines use shrink film to wrap around products or packages. After heating, the shrink film shrinks and tightly wraps the product or package, fully displaying the appearance of the item, improving its marketability, and increasing its aesthetic appeal and perceived value. Items packaged by a heat shrink machine are sealed, moisture-proof, and pollution-proof, and protect the goods from external impacts, providing a certain degree of cushioning. Especially when packaging fragile items, it can prevent the contents from scattering when the container breaks. In addition, it can reduce the possibility of products being opened or stolen.

[0003] Currently used heat shrink film packaging machines typically use a servo cylinder or a swing servo cylinder as a power source to lift the top plate and reciprocate to lift the packaging box. However, there is a lack of buffer components between the power source and the top plate. During use, the impact of the reciprocating motion will cause the equipment to run unevenly, and the swing height is not easy to adjust, which limits its use. This utility model proposes a new solution to the above problems. Summary of the Invention

[0004] In view of the problems existing in the prior art, the purpose of this utility model is to provide a servo top box device for a transparent three-dimensional film packaging machine to solve the technical problems mentioned in the background art.

[0005] To solve the above problems, the present invention adopts the following technical solution:

An L-shaped box-pressing adjustment arm is bolted to the mounting frame, and a box-pressing safety mechanism is provided at the end of the horizontal section of the box-pressing adjustment arm. Wherein:

[0007] The buffer limiting mechanism includes a horizontal plate, a T-shaped seat, a buffer block, a spring, and a telescopic rod. The horizontal plate is bolted to the bottom side of the vertical mounting plate, the T-shaped seat is bolted to the upper end face of the horizontal plate, the buffer block is positioned directly above the T-shaped seat, the spring and the telescopic rod are positioned between the buffer block and the T-shaped seat, the spring is sleeved on the telescopic rod, the top end of the telescopic rod and the top end of the spring are fixed to the lower end face of the buffer block, the bottom end of the telescopic rod and the bottom end of the spring are mounted on the upper end face of the T-shaped seat, and the top end of the guide rod is rotatably connected to the T-shaped seat.

[0008] The pressure box safety mechanism includes a conformal bracket, an adjusting plate, and a pressure box adjusting block. The conformal bracket is installed at the lower part of the L-shaped pressure box adjusting arm, and a slide rail is provided at the end of the conformal bracket. The pressure box adjusting block is slidably connected to the slide rail in the vertical direction. A through groove is opened on the pressure box adjusting block in the vertical direction. The adjusting plate is fixed on the pressure box adjusting arm, and a threaded hole is provided on the adjusting plate. The through groove and the threaded hole are matched.

[0013] In any of the above embodiments, it is preferred that a protective seat is provided on the outer side of the drive unit.

[0014] Compared with existing technologies, the advantages of this utility model are:

[0024] The design of the top plate 2, drive unit 3, and buffer limiting mechanism 8 utilizes the operation of the drive unit 3 to drive the drive swing rod 5 to rotate, thereby driving the transmission rod 8 to swing up and down, and thus driving the top plate 2 to move up and down to support the items on the processing table.
