[0015] 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.

[0016] See also Figure 1-2 The utility model provides a technical solution: a paper product waste pulverizing device, comprising a box body 1, a pulverizing chamber 2 and a feeding chamber 3 are arranged in the cavity of the box body 1, and the pulverizing chamber 2 and the feeding chamber 3 are separated by a filter plate 4; a pulverizing roller 5 is longitudinally arranged in the pulverizing chamber 2, and the number of the pulverizing rollers 5 is 2, and they are respectively arranged on the left and right sides of the pulverizing chamber 2; a mounting box 6 is arranged on the side wall of the box body 1, and the mounting box 6 is connected with the feeding chamber 3, and a powerful fan 7 is arranged in the mounting box 6, and the air outlet end of the powerful fan 7 is inclined upward, and an arc filter plate 8 is arranged between the mounting box 6 and the feeding chamber 3, and the setting of the arc filter plate 8 prevents the fallen waste from entering the cavity of the concealed mounting box 6 and affecting the use of the powerful fan 7.

[0017] Specifically, a discharge port 9 and a support leg 10 are provided at the lower end of the box body 1. The discharge port 9 is provided in the middle of the lower end of the box body 1, and the support legs 10 are arranged in a circular array around the discharge port 9. The waste material entering the feeding chamber 3 after crushing is discharged through the discharge port 9, which is convenient for unified collection.

[0018] Specifically, a support frame 11 is provided at the upper end of the box body 1, and a drive motor 12 is provided on the support frame 11. A coupling 13 is provided at the driving end of the drive motor 12, and the coupling 13 is connected to the crushing roller 5. The coupling 13 refers to a device that connects two shafts or a shaft and a rotating part, rotates together during the process of transmitting motion and power, and does not disengage under normal circumstances. It serves as a safety device to prevent the crushing roller 5 from being subjected to excessive load and plays a role in overload protection.

[0019] Specifically, a conduction rod 14 is provided on the outer edge of the filter plate 4, the outer end of the conduction rod 14 extends to the outside of the box body 1 and is connected to a vibration motor 15. When stubborn larger waste is retained on the filter plate 4, that is, the powerful fan 7 is not enough to blow it up, the vibration motor 15 is started, and the powerful fan 7 is used in conjunction with the larger waste to vibrate and blow it up, thereby assisting the use of the powerful fan 7.

[0020] Specifically, a driven shaft 16 is provided at the bottom end of the crushing roller 5. The driven shaft 16 extends to the bottom end of the housing 1 and is installed at the bottom end of the housing 1 through a bearing seat. The arrangement of the driven shaft 16 ensures that the crushing roller 5 has sufficient stability.

[0021] Working principle: When the utility model is working, a crushing chamber 2 is provided. After the staff puts the paper product waste into the crushing chamber 2, the driving motor 12 is started to drive the crushing roller 5 to rotate. The crushing roller 5 rotates at a high speed to crush the waste. Since the crushing chamber 2 and the feeding chamber 3 are separated by the filter plate 4, the crushed waste passes through the filter screen on the filter plate 4 and falls into the feeding chamber 3. The larger waste is blocked by the filter plate 4. The powerful fan 7 is started to blow up the waste that falls on the filter plate 4 and continues to be crushed by the crushing roller 5, so as to avoid the larger waste from being retained on the filter plate 4, and the crushing effect can be improved.
