Detailed Description

In order to make those skilled in the art better understand the technical solution of the present invention, the following detailed description of the embodiments of the present invention will be made with reference to the accompanying drawings.

FIG. 1 is a schematic representation of the operation of a prior art cotton pulp roll shredding system. As shown in fig. 1, the feed box 1 serves as a cotton pulp roll feeding device for feeding a cotton pulp roll to the crusher 3, and constitutes a cotton pulp roll crushing system together with the crusher 3. In the conventional cotton pulp roll crushing system, when feeding a cotton pulp roll (hereinafter referred to as a material), an operator needs to open the cotton pulp roll, manually pass through the conventional feed box 1, and thread the cotton pulp roll to the other side of the sound insulation wall 2, that is, one side of a room provided with the crusher 3. After the staff pass through the material, the material enters the other side of the sound insulation wall 2 through the door of the room, the material is put into the feeding roller 4 of the crusher 3, the material returns to the outside of the sound insulation wall 2 after being placed, and the feeding roller 4 is started by pressing the feeding roller switch 5. The conditions in the room of the crusher 3 can be observed through the observation window 6.

The existing feed box 1 cannot go deep into the crusher 3 too far for a long time because of the need to reserve an overhaul space (a space between the sound-insulating wall 2 and the crusher 3), and meanwhile, in order to reduce noise, the existing feed box 1 is fixed on the sound-insulating wall 2, so that an operator must enter a room of the crusher 3 to feed. The feeding roller 4 is started by returning to the original position after feeding, thereby increasing the labor intensity and the labor time. Moreover, when feeding, the crusher 3 is already started and the staff entering the room of the crusher 3 is directly affected by noise. Meanwhile, the noise is transmitted out through the existing material inlet box 1, and the noise volume outside the room of the pulverizer 3 is increased.

In order to solve the above problems, an embodiment of the present invention provides a cotton pulp roll feeding device and a cotton pulp roll crushing system including the cotton pulp roll feeding device, wherein the cotton pulp roll feeding device is modified to improve noise emitted when the cotton pulp roll is conveyed, improve an operating environment of an operator, and reduce labor intensity.
