Technical Field

[0001] This utility model belongs to the technical field of auxiliary devices for mulch film production, and more specifically, it relates to an auxiliary device for biodegradable mulch film extrusion with adjustable additive ratio. Background Technology

[0002] Mulch film, also known as ground cover film, is a plastic film produced by the industrial sector specifically for covering crops on the ground. Ordinary plastic mulch film includes colorless transparent plastic mulch film and colored plastic mulch film. The former has high light transmittance and a significant warming effect, but it is prone to weed growth; the latter, such as black mulch film, can stabilize soil temperature and inhibit weed growth, silver reflective mulch film can lower soil temperature, and silver-gray bicolor mulch film can repel aphids and inhibit virus occurrence. Biodegradable mulch film is widely used in agricultural production. Its production process usually requires the addition of various additives to improve the degradation performance and mechanical properties of the mulch film.

Combined with the positioning and bearing function of the supporting box frame, it ensures a stable and orderly delivery path for the additives, laying a solid foundation for the subsequent addition process. The motor drives the worm gear, worm wheel, and gears in a coordinated manner, which in turn moves the adjustable support frame flexibly. The inner space of the quantitative carrier frame can be adjusted as needed to easily accommodate the loading of additives with different dosage requirements. The drive motor controls the rotation of the quantitative carrier frame through gear transmission, so that the addition slot is precisely aligned with the top and bottom of the closed support plate. When aligned with the top, the quantitative loading of the additive is completed. When aligned with the bottom, the quantitative additive is introduced into the addition tube through the addition slot. The whole process achieves precise control of the quantitative loading of the additive. Ultimately, the conveyor motor, in conjunction with the conveyor screw, pushes the quantitative additive, forming a complete closed loop of "positioning-quantification-conveyance" in the additive addition process. This design not only improves the automation level of additive addition and reduces errors caused by manual intervention, but also ensures the accuracy of additive dosage and the stability of the addition process through the coordinated operation between structures. This effectively improves the efficiency and precision of the additive addition process in extrusion production, providing strong support for improving production quality.
