[0002] Cartons are the most widely used packaging products. Depending on the materials used, there are corrugated boxes, single-layer cardboard boxes, etc., with various specifications and models. After the use of cartons, they are generally collected and then processed for reuse. Cartons need to be crushed after recycling.

[0003] The Chinese patent with publication number CN116651897A discloses an intelligent recycling device for carton processing waste, comprising a crushing box, a support frame is fixedly connected to the bottom of the crushing box, a controller is fixedly connected to the outside of the crushing box, a motor is fixedly installed on the outside of the crushing box, and a rotating shaft is fixedly connected to the output end of the motor;

In addition, the surface of the discarded cartons often contains impurities such as dust, which will be generated when they are crushed, and the dust is easy to overflow from the feed port.

[0005] For this reason, a waste material crushing device for carton processing is proposed. Utility Model Content

More specifically, discarded cartons are added into the pulverizing mechanism 1 through the feed port 2. When the cartons are added, the cartons push the baffle plate 3 to flip over, thereby stretching the tension spring 4. When the cartons completely enter the feed port 2, the feed port 2 is closed through the baffle plate 3 under the elastic force of the tension spring 4, thereby preventing dust from overflowing when the pulverizing mechanism 1 crushes the cartons. The crushed paper scraps fall to the conveying part of the discharging mechanism 5, and are transported to the compression mechanism 6 through the discharging mechanism 5. The paper scraps are accumulated and squeezed into blocks through the compression mechanism 6, and then the blocky paper scraps are transported through the discharging mechanism 5 and the guide plate 7.

[0026] The crushing mechanism 1 includes a crushing box 101, and two sets of rotating shafts 102 are rotatably plugged into the inner walls of the front and rear sides of the crushing box 101. A first motor 103 is fixedly installed on the rear side wall of the crushing box 101. The output end of the first motor 103 and the rear end of the right rotating shaft 102 are fixedly installed. Gears 104 are fixedly installed on the front side walls of the two sets of rotating shafts 102. Crushing wheels 105 are fixedly sleeved on the surfaces of the two sets of rotating shafts 102. More specifically, the right rotating shaft 102, the crushing wheel 105 and the gear 104 are driven to rotate by the first motor 103, and the left rotating shaft 102, the crushing wheel 105 and the gear 104 are meshed with each other, so that the carton is crushed by the rotation of the two sets of crushing wheels 105.

[0027] The discharging mechanism 5 includes a discharging box 501, the bottom surface of the crushing box 101 is fixedly mounted with the discharging box 501, the front and rear side walls of the discharging box 501 are rotatably mounted with a conveying wheel 502, the front side wall of the discharging box 501 is fixedly mounted with a second motor 503, and the output end of the second motor 503 and the front end of the left conveying wheel 502 are fixedly mounted, and the surface of the conveying wheel 502 is meshed with a conveying belt 504. More specifically, the left conveying wheel 502 is driven to rotate by the second motor 503, and the conveying belt 504 is rotated by the conveying wheel 502, and the paper scraps crushed by the crushing mechanism 1 are output from the discharging box 501 by the rotation of the conveying belt 504.

More specifically, the third motor 602 drives the squeezing box 603 to rotate, so that the top surface of the squeezing box 603 and the top surface of the conveyor belt 504 are in contact, so that the paper scraps transported by the conveyor belt 504 can enter the squeezing box 603 and accumulate. After a certain amount of accumulation, the second motor 503 stops running, and the first hydraulic rod 605 drives the mounting frame 606, the second hydraulic rod 607 and the squeezing plate 608 to move vertically downward, and the squeezing plate 608 is used to squeeze the paper scraps in the squeezing box 603 into blocks. After squeezing, the squeezing plate 608 is retracted by the second hydraulic rod 607, and the squeezing plate 608 is lifted vertically by the first hydraulic rod 605, and then the squeezing box 603 is reversed by the third motor 602, and the second motor 503 is started to output the formed paper scraps through the conveyor belt 504. The above operations are repeated to squeeze and pack the paper scraps.

[0029] A blocking bar 21 is fixedly installed at the inner bottom of the feed port 2. When the baffle 3 is closed, the bottom end of the baffle 3 and the end surface of the blocking bar 21 are arranged in a close fit.
