However, the shape of the tooth tip seal strip is vortex-shaped, occupying a large space, but the volume of the tooth tip seal strip is very small. Therefore, a large space is required for the placement and removal of the tooth tip seal strip, which greatly increases the floor space of the entire equipment during material handling. If multiple tooth tip seal strips are placed simultaneously so that they can be taken out sequentially during material handling, due to the large floor space occupied by the tooth tip seal strips, it is not conducive to the design and transmission of the machinery.

Multiple tooth top sealing rings can be placed on the feeding part 1, so that multiple materials can be placed in a limited space, saving the space of the equipment. And through holes 3 are opened in the feeding groove 2, so that after the material is placed in the feeding groove 2, it will not form a seal with the feeding groove 2. Thus, through the setting of the through holes 3, it is more convenient to take out the material outward; and through the negative pressure adsorption method, the material can be taken out normally. When the material needs to be placed, the material can be blown outwards.

[0030] Preferably, a plurality of the negative pressure suction holes 6 are provided, and the plurality of negative pressure suction holes 6 form an adsorption area for adsorbing the material; the shape of the adsorption area matches the shape of the feeding groove 2.
