Description

Technical Field

[0001] This utility model relates to the field of packaging bag winding technology, and in particular to a winding device for processing plastic packaging bags. Background Technology

[0002] A winding device for processing plastic packaging bags is a piece of equipment used to wind processed plastic films or packaging bags into regular rolls. It mainly consists of a winding shaft, a drive system, and a tension control system. The drive system drives the winding shaft to rotate, while the tension control system ensures that the film tension is stable during the winding process, avoiding problems such as wrinkles and loosening. This ensures that the finished product after winding is neat, easy to store and transport, and is widely used in plastic packaging production lines. It is one of the important pieces of equipment for realizing continuous and automated production of packaging materials.

[0003] Traditional plastic packaging bag winding equipment suffers from poor stability in the clamping and positioning process during production. It often uses a single fixed clamp, which cannot adapt to different sizes of packaging bags. This can easily lead to bag displacement and wrinkling during winding, affecting product quality. The cutting operation is inefficient, relying heavily on manual cutting or fixed blades. The cutting position is inaccurate, resulting in uneven cuts. Furthermore, manual operation poses safety hazards. The equipment has a low degree of automation, requiring frequent manual intervention in winding, cutting, and other processes, making continuous production difficult and hindering capacity expansion. Maintenance costs are high, the mechanical structure is complex, and downtime for maintenance is long, increasing the company's operating costs. Utility Model Content

[0004] The purpose of this utility model is to solve at least one of the technical problems existing in the prior art, and to provide a winding device for processing plastic packaging bags. This solves the problem that traditional plastic packaging bag winding devices mostly use hard metal clamps, which are prone to causing surface scratches and wear when in contact with the packaging bags, affecting the appearance and quality of the finished product. Moreover, the clamp pressure is not adjustable. When facing packaging bags of different materials and thicknesses, either the clamp is not tight enough, resulting in loose winding and misalignment, or the pressure is too high, causing the packaging bags to deform and be damaged. Traditional devices are difficult to adapt to diverse production needs. When changing product specifications, the equipment needs to be frequently adjusted, which is time-consuming and labor-intensive, and greatly reduces production efficiency.

[0005] This utility model also provides a winding device for processing plastic packaging bags, including a base, a fourth support column fixedly connected to the upper end of the base, a fixed plate fixedly connected inside the fourth support column, a lifting plate slidably connected inside the fourth support column, a limit rod fixedly connected to the upper end of the lifting plate, a third threaded rod fixedly connected to the upper end of the lifting plate, a movable block threadedly connected to the outer surface of the third threaded rod, a blade fixedly connected to the lower end of the movable block, a second threaded rod threadedly connected inside the lifting plate, a support plate fixedly connected to the upper end of the base, a second turntable provided on one side of the support plate, a first threaded rod fixedly connected inside the second turntable, a movable column threadedly connected to the outer surface of the first threaded rod, a connecting rod movably fitted on the other side of the movable column, a fixed seat movably fitted on the other side of the connecting rod, a sliding rod fixedly connected to the other side of the fixed seat, a first turntable movably fitted on the other side of the first threaded rod, and a fourth roller fixedly connected between the first and second turntables.

[0013] Beneficial effects:

[0014] 1. The lifting plate and the fixed plate work together to flexibly adjust the spacing and precisely clamp packaging bags of different thicknesses and sizes, ensuring stability during the winding process and effectively avoiding deviation and wrinkles, thus improving the flatness and aesthetics of the product. In the cutting process, the blade at the top of the lifting plate is precisely controlled by a motor, which can achieve automated and high-precision cutting with neat and smooth cuts. This not only improves cutting efficiency but also eliminates the risks of manual operation. The winding, clamping, and cutting processes can be completed automatically in one integrated manner, reducing manual intervention and improving production efficiency.

[0015] 2. The rubber pad is soft and elastic, providing sufficient friction to prevent slippage when in contact with the packaging bag, while avoiding damage to the bag surface and ensuring product quality. Its pressure can be flexibly adjusted according to the bag material and thickness to achieve precise clamping, ensuring tight and flat winding and preventing loosening and misalignment. During the rotation and winding process, the elastic cushioning of the rubber pad effectively absorbs vibration, reducing wrinkles and uneven winding of the packaging bag. This device can quickly adapt to different packaging bag specifications, allowing for production switching without complex adjustments, improving production flexibility and efficiency, and reducing enterprise production costs.
