The traditional core body is mixed with high molecular water-absorbing material and wood pulp, and is covered with wet-strength paper or hydrophilic spun-bond nonwoven fabric. The cotton core absorber has a relatively thick thickness. After water absorption, water is easily accumulated in the water injection part and is not easy to diffuse. Due to the influence of gel blocking, the utilization rate of high molecular water-absorbing material is low, and the water locking capacity also has certain limitations.

The lower part of the hopper is a belt conveying assembly driven by a variable frequency motor. One end of the belt conveying assembly is provided with a receiving hopper. Two high-pressure air pipes are arranged at one end of the receiving hopper to blow the high molecular material into the molding box of the production line. The other end of the receiving hopper is provided with a material application channel. A material baffle is arranged on the upper side of the receiving hopper. The working principle of the device is as follows: the high molecular small particles are stored in the material cavity and fall onto the belt conveying assembly under the action of their own gravity, and then are conveyed to the right and fall into the receiving hopper. Finally, the high molecular material is applied to the molding box of the production line through the action of high-pressure blowing. In this process, the amount of material conveyed on the belt can be controlled by the adjusting plate, and the belt conveying speed and the host speed are corresponded by adjusting the speed of the variable frequency motor, so that the applied high molecular material is quantitatively conveyed to the molding box.

[0004] The above-mentioned technology has the following disadvantages: the high molecular material is adsorbed and accumulated together when it falls onto the belt conveying assembly by its own gravity. During the discharging process, it is easy to adhere to the storage cylinder, which is not conducive to the conveying of the high molecular material. UTILITY MODEL CONTENTS
