[0011] The beneficial effects of the utility model are:

[0012] A sound collecting cover is provided around the motor and the pelletizing chamber, and a plurality of silencers are provided around the sound collecting cover. The silencer ports of the silencers are connected to the sound collecting cover. The sound collecting cover transmits the noise generated by the motor and the pelletizing chamber to the inside of the silencer, which is then absorbed by the silencer, thereby effectively reducing the noise. The pelletizer adopts this structure and has a good noise reduction effect even after long-term use. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0017] The present invention is further described in detail below in conjunction with specific implementation methods.

[0018] Pelletizer Figure 1 As shown, it includes a box body 1, a support plate 2 is provided inside the box body 1, and a sound collecting cover 8 is provided on the top surface of the support plate 2. The pelletizing chamber 3 and the motor 5 are located in the cover cavity of the sound collecting cover 8, wherein: the pelletizing chamber 3 is installed on the top surface of the support plate 2, and a pelletizing device 4 is provided in the pelletizing chamber 3; the motor 5 is installed next to the pelletizing chamber 3, and drives the pelletizing device 4 in the pelletizing chamber 3 to pelletize the plastic. Specifically, the pelletizing device 4 includes a main pelletizing roller 41 and a secondary pelletizing roller 42, the main pelletizing roller 41 is connected to a main gear 410, and the secondary pelletizing roller 42 is connected to a secondary gear 420 meshing with the main gear 410, and the output end of the motor 5 is connected to the main pelletizing roller 41 through the main gear 410, and the main gear 410 drives the secondary gear 420 to make the secondary pelletizing roller 42 pelletize the plastic.

[0019] like Figure 2 As shown, the front of the box body 1 is provided with an external feed port 9, and the edges of both sides of the external feed port 9 are welded with limit plates 14, and the upper and lower ends of the limit plates 14 are equipped with two sets of guide rollers 15 that cooperate with each other; Figure 3As shown, the side wall of the pelletizing chamber 3 is provided with an inner feed port 10; the sound collecting cover 8 is provided with a middle feed port 11. The outer feed port 9, the middle feed port 11 and the inner feed port 10 are aligned. The staff operates the control panel 12 provided on the side of the box body 1 to control the motor 5 to turn on, and then puts the plastic between the two groups of guide rollers 15 of the outer feed port 9, and introduces it into the pelletizing chamber 3 through the middle feed port 11 and then through the inner feed port 10. The motor 5 drives the main pelletizing roller 41 and the secondary pelletizing roller 42 to cut the plastic into particles of the same size, and the particles are guided out through the discharge channel 16 provided just below the pelletizing chamber 3 to the discharge port 13 opened on the side of the box body.

[0020] Two silencers 6 are provided on the top surface of the support plate 2 beside the sound collecting cover 8.
