Description

Technical Field

[0001] This utility model relates to the field of hardware and plastic parts manufacturing, specifically to a heat shrink device for plastic packaging film. Background Technology

[0002] In the production of hardware and plastic parts, plastic packaging films are used to prevent moisture or contamination. This is typically done manually, which is labor-intensive and prone to uneven packaging and leaks, leading to product moisture absorption and quality issues. To reduce labor costs, companies use film packaging machines. However, after sealing, the film often doesn't adhere well to the box, making it prone to misalignment during transport. Misalignment tears the film, rendering it ineffective at preventing moisture and contamination, requiring repackaging and significantly increasing manufacturing costs. Summary of the Invention

[0003] In order to solve one or more technical problems existing in the prior art, the purpose of this application is to provide a plastic packaging film heat shrink device that can bond the plastic packaging film to the packaged product, avoid misalignment and damage of the packaging film, and reduce the manufacturing cost of enterprises.

[0004] To address the aforementioned technical problems, this application employs the following technical solution: a heat-shrinkable plastic packaging film device, comprising a base frame, a conveyor platform mounted on the base frame, a conveyor belt mounted on the conveyor platform, a shrink box mounted on the conveyor platform above the conveyor belt, and a heating element mounted on top of the shrink box. The shrink box contains a flipping device. The packaged product, sealed with film, is placed on the conveyor belt and enters the shrink box. The heating element heats the film, causing it to shrink and adhere to the packaged product. The flipping device flips the packaged product, ensuring even heating of the film and increasing adhesion. This prevents misalignment and damage to the packaging film, reducing manufacturing costs for the enterprise.

[0005] Preferably, the shrink box includes a first box and a second box. Both the top of the first box and the top of the second box are equipped with a heater fan communicating with the heating element. The flipping device is located between the first box and the second box. The heater fan evenly blows warm air from the heating element into the first box and the second box. The first box heats and shrinks the film on the top of the packaged product. When the product passes through the flipping device, it flips over. The second box heats and shrinks the film on the flipped side of the packaged product, ensuring that the film wrapping the product is heated evenly.

[0006] Preferably, the flipping device includes a rotating shaft connected to a shrink box and at least two rotating plates evenly distributed on the rotating shaft. Each rotating plate has an inclined plate at one end and a shovel at the other end. When the rotating shaft rotates, the shovel scoops up the packaged product and rotates upwards. The packaged product slides along the inclined plate between adjacent rotating plates. With continued rotation, the packaged product slides out along the inclined plate, thus flipping the packaged product. The structure is simple and the operation is convenient.

[0007] Preferably, the end of the shovel plate is provided with a buffer ball, which is made of rubber. The rubber buffer ball can prevent the shovel plate from scratching the film and plays a protective role.

[0008] Preferably, the shrink tub is provided with a transparent observation window on the front side, and curtains are provided at both the inlet and outlet of the shrink tub. The transparent observation window facilitates observation of the internal packaging products' turning and conveying, allowing for timely handling; the curtains provide insulation, preventing heat loss.

[0009] Preferably, the base frame is equipped with a height adjustment plate connected to the conveyor table, and the height adjustment plate is fixed to the base frame and the conveyor table by nuts. The height adjustment plate can adjust the height of the conveyor table, making it convenient for operators to handle packaged products.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] The plastic packaging film heat shrinking device using the above technical solution places the sealed packaged product on a conveyor belt and enters the shrink box. The heating element heats the film, causing it to shrink and adhere to the packaged product. The flipping device flips the packaged product, ensuring that the film wrapping the product is heated evenly and increasing the adhesion. This prevents misalignment and damage to the packaging film and reduces the company's manufacturing costs. Attached Figure Description
