Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of material stacking and feeding, especially relates to a hydraulic device for material stacking and feeding. BACKGROUND

[0002] The hydraulic device plays an important role in the field of material stacking and feeding. It provides stable and adjustable power output through a hydraulic drive system, and is suitable for the handling and stacking of various heavy, irregular or easily damaged materials. With the development of industrial automation, traditional hydraulic devices gradually evolve towards intelligence and self-adaptation to meet the needs of efficient and precise operation under complex working conditions.

[0003] Most existing material stacking and feeding equipment uses simple mechanical clamping structures, and their technical principles are based on fixed-mode mechanical linkage. Usually, a pre-set rigid clamp is used to drive a mechanical arm or support with a motor, and the material is grabbed and carried with a fixed clamping force and angle. These devices assume that the material has uniform shape and hardness characteristics in design, and the clamping force cannot be flexibly adjusted during operation, completely relying on pre-set mechanical parameters to perform actions.

[0004] However, this traditional material stacking and feeding equipment has obvious drawbacks. Because the shapes of materials in actual production are different, and the hardness is also different, there are fragile materials that are fragile and easy to break, soft materials that are soft in texture, and hard materials that are hard and irregular in shape. The existing equipment cannot automatically adjust the clamping force according to the shape or hardness of the material. When facing fragile or soft materials, the fixed clamping force is easy to exceed the bearing range of the material, causing the material to be crushed and causing product loss. For hard materials, it is difficult to adaptively adjust the clamping force distribution, and it is easy to cause uneven stress, causing the material to slip during handling, affecting production progress, and even causing safety accidents, greatly limiting the practicality and reliability of the material stacking and feeding equipment in complex production environments. Therefore, the hydraulic device for stacking and feeding materials is proposed to solve the above problems. CONTENT OF THE UTILITY MODEL
