[0020] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is described in detail below with reference to the following embodiments. It should be understood that the following text is only used to describe one or several specific embodiments of the present invention and does not strictly limit the scope of protection of the present invention.

[0021] like Figure 1-3 、 Figure 5 As shown, a waste paper shredding device for carton processing includes a shredding bin 1, a knife shaft 104 is rotatably assembled in the middle of the shredding bin 1, a feeding port 101 is symmetrically opened on both sides of the top of the shredding bin 1, and a discharge port 115 is symmetrically opened at the bottom of the shredding bin 1. A baffle 103 is fixedly connected to the top of the inner wall of the shredding bin 1 and located between the two feeding ports 101. A baffle 103 is fixedly connected to the bottom of the inner wall of the shredding bin 1 and located between the two discharge ports 115. There is a baffle three 111, and baffle two 106 are symmetrically fixedly connected to the inner wall of the crushing bin 1 on both sides. The baffle two 106 is set to a wedge with an inclined side. The baffle one 103 and baffle three 111 are set to a triangle. The baffle two 106, baffle one 103 and baffle three 111 are all fixedly set on the outside of the knife shaft 104, and one end of the baffle two 106 and baffle one 103 is evenly spaced with tooth grooves for the knife shaft 104 to rotate through.

[0022] According to the above structure, baffle 1 103 is arranged above the cutter shaft 104, baffle 2 106 is arranged on both sides of the cutter shaft 104, and baffle 3 111 is arranged below the cutter shaft 104, thereby dividing the interior of the shredding bin 1 into two feed chambers and two discharge chambers. Waste paper is fed into the feed chamber inside the shredding bin 1 from the two feeding ports 101, driving the cutter shaft 104 to rotate, and the cutter shaft 104 tears the waste paper in one chamber into pieces by passing through the tooth grooves of baffle 2 106, and the cutter shaft 104 tears the waste paper in the other chamber into pieces by passing through the tooth grooves of baffle 1 103. The debris will fall to the lower part of the shredding bin 1 and be discharged through the discharge port 115. The inclined surface of baffle 2 106 facilitates the waste paper to slide onto the surface of the cutter shaft 104, preventing the waste paper from being shelved.

[0023] Refer to the attached Figure 1 、 Figure 3-5The outside of the feeding port 101 is movably fastened with a buckle plate 102, and one side of the buckle plate 102 is fixedly connected to a pressure plate 105 inside the crushing bin 1, and a support plate 107 is slidably provided on the inner wall of the baffle three 111. The bottom two ends of the crushing bin 1 are mirror-rotatably connected to a rotating shaft 113, and one side of the rotating shaft 113 is fixedly connected to an insert plate 114. The bottom of the support plate 107 is penetrated by a through groove 112 for the insert plate 114 to be rotatably embedded. The inner wall of the baffle three 111 and the upper part of the support plate 107 are slidably provided with a brush seat 108, and the brush seat 108 is movably fitted with the support plate 107. The two sides of the brush seat 108 and the inside of the baffle three 111 are fixedly connected with wing plates 110, and one end of the brush seat 108 and the bottom of the knife shaft 104 are fixedly connected with a brush 109.

[0024] According to the above structure, the closed chamber formed by the buckle engagement of the crushing bin 1 and the buckle plate 102 can prevent debris from flying out, the pressure plate 105 can press the waste paper toward the cutter shaft 104, and the brush 109 is attached to the bottom of the cutter shaft 104 to sweep away the debris adhered to its surface. By rotating the rotating shaft 113, the panel 114 is driven to leave the groove 112, and the support plate 107 is slid out, and the brush holder 108 falls to the bottom of the crushing bin 1, and the brush 109 can be replaced and maintained. The brush 109 can be reinstalled according to the above steps, and the wing plate 110 is pressed against the baffle. The top of the inner wall of the three 111 limits the brush holder 108 to prevent the brush holder 108 from continuing to move up and rubbing against the cutter shaft 104; the utility model adds a feeding port 101 and uses a cutter shaft 104 to crush the paper materials of the two feeding ports 101 at the same time, so as to give full play to the effectiveness of the cutter shaft 104, improve the crushing efficiency, and crush more waste paper within a specified time. It can also prevent the paper scraps generated by the crushing from flying out of the crushing bin 1, and sweep away the debris adhering to the cutter shaft 104, so as to avoid the debris causing a dirty environment and the cutter shaft 104 malfunction.

[0025] The working principle of the present invention is as follows: baffle 103 is arranged above the cutter shaft 104, baffle 2 106 is arranged on both sides of the cutter shaft 104, and baffle 3 111 is arranged below the cutter shaft 104, thereby dividing the interior of the crushing bin 1 into two feeding chambers and two discharging chambers. Waste paper is fed into the feeding chamber inside the crushing bin 1 from the two feeding ports 101, and the cutter shaft 104 is driven to rotate. The cutter shaft 104 tears the waste paper in one chamber into pieces by passing through the tooth grooves of baffle 2 106, and the cutter shaft 104 tears the waste paper in the other chamber into pieces by passing through the tooth grooves of baffle 1 103. The debris will fall to the lower part of the crushing bin 1 and be discharged through the discharge port 115. The inclined surface of baffle 2 106 facilitates the waste paper to slide onto the cutter shaft 1 04 surface to prevent waste paper from being shelved. The closed chamber formed by the buckle engagement of the crushing bin 1 and the buckle plate 102 can prevent debris from flying out. The pressing plate 105 can press the waste paper toward the knife shaft 104. The brush 109 is attached to the bottom of the knife shaft 104 to sweep off the debris adhered to its surface. By rotating the rotating shaft 113, the panel 114 is driven to leave the groove 112, and the support plate 107 is slid down and out. The brush holder 108 then falls to the bottom of the crushing bin 1, and the brush 109 can be replaced and maintained. The brush 109 can be reinstalled according to the above steps, and the wing plate 110 is pressed against the top of the inner wall of the baffle three 111 to limit the brush holder 108 to prevent the brush holder 108 from continuing to move up and rubbing against the knife shaft 104.

[0026] The above description is merely a preferred embodiment of the present invention. It should be noted that those skilled in the art may make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications should be considered within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described or explained in this invention shall, unless otherwise specified or limited, be implemented in accordance with conventional means in the art.
