[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] like Figure 1 As shown, the utility model provides a dust collector for preparing an epoxy resin composition, comprising: a feed hopper 1, which is arranged at the feed port of an external extruder and is connected to the extruder. An operator feeds the extruder by putting materials into the feed hopper 1.

[0023] A disc-shaped recessed structure is provided in the feed hopper 1 to receive the spilled dust.

[0024] Specifically, Figure 1 , Figure 3 As shown, a feeding port 2 is opened at the center of the feeding hopper 1, and a protrusion 3 is arranged around the feeding port 2. The protrusion 3 is an annular arc surface protruding upward. The protrusion 3 is connected to the inner recess 4. The inner recess 4 is an annular arc surface concave downward. The protrusion 3 and the inner recess 4 form a disc-shaped recessed structure.

[0025] like Figure 2 As shown, the feed hopper 1 is connected to a collecting box 7, which is connected to a vacuum device (not shown in the figure). The vacuum device is an exhaust device used to provide negative pressure to the feed hopper 1. The collecting box 7 collects the spilled dust under the action of the vacuum device.
