Description

[0002] A sponge is a porous material with excellent water absorption. Commonly used sponges are made of wood cellulose fibers or foamed plastic polymers. There are also natural sponges made from sponge animals; most natural sponges are used for body cleaning or painting.

[0003] Sponges have a wide range of uses. Large sponges can be used in the manufacture of large toys or furniture. Sometimes customers need to perform subsequent cutting and processing themselves. These large sponges can be tens of meters long. The transfer between production lines and conveyor lines is generally achieved through a gripper mechanism. Currently, large sponge gripper mechanisms generally use multiple grippers working together, and then use a crane and electric hoist to achieve suspension, gripping and transfer. However, this split gripper structure has poor stability when gripping sponges, and each gripper mechanism requires a motor or a set of cylinders for driving, which increases costs. Therefore, there is an urgent need for an improved technology to solve this problem in the existing technology. Utility Model Content

The lower toothed disc 10, through its engagement with the racks 18 on the inner walls of the left telescopic rod 6 and the right telescopic rod 7, causes the left telescopic rod 6 and the right telescopic rod 7 to move in opposite directions at the same speed, thereby driving the left upright rod 8 and the right upright rod 9 to move closer or further apart, thus clamping or releasing the sponge through the upper clamping rod 19 and the lower clamping rod 20.
