Description

Technical Field

[0001] The utility model relates to the technical field of material handling devices, in particular to a material gripper structure. Background Art

[0002] There are currently two main ways to load large packaging bag materials in the market: 1. Manual handling: transporting materials to the cargo box through a conveyor line and then stacking them manually; 2. Conveyor head palletizing: placing bags in the car by driving a motor to control the conveyor belt and the head structure to move forward, backward, and up and down. The above two methods have high application costs and great limitations, and can no longer meet current market demand. Therefore, some markets will use mechanical grippers to carry out logistics loading, so as to improve the efficiency of material loading.

[0003] The existing gripper has a fixed length. Therefore, when grasping materials with longer sides, the gripper is not long enough to grasp the materials deeply, making it impossible for the gripper to grasp the materials stably, especially for irregular objects. It is necessary to grasp the bottom of the guide material, resulting in unstable material grasping, and even the material cannot be grasped or the material falls off the gripper. At this time, it is necessary to replace the longer gripper, but replacing the gripper is time-consuming and labor-intensive. Therefore, a material gripper structure is needed. Utility Model Content
