DETAILED DESCRIPTION

[0036] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] See attached Figure 1-11 A waste cardboard recycling and shredding device comprises a support frame 1, a plurality of universal wheels are arranged at the bottom of the support frame 1 to facilitate the movement of the device, and further, a threaded support leg is installed at the bottom of the support frame 1 to realize the positioning of the device;

[0038] A crushing bucket 2 is provided on the support frame 1, and a crushing mechanism is provided inside the crushing bucket 2 for crushing the recycled waste cardboard boxes. The bottom wall of the feeding channel of the crushing bucket 2 is an inclined plate 21, and the side facing the inlet is higher than the other side. When the waste cardboard boxes enter the feeding channel through the feeding port, they can slide into the crushing chamber of the crushing bucket 2 for crushing.

[0039] A sealing cover 3 is rotatably connected to the crushing bucket 2 to cover the upper side of the feed opening of the crushing bucket 2 to prevent dust from floating out through the feed opening during the crushing process, thereby effectively preventing dust from leaking out.

[0040] The inner cavity of the crushing bucket 2 is provided with a rotatable baffle 4 to realize the opening or closing of the feed channel. When waste cartons are added into the crushing bucket 2 through the feed port, the baffle 4 closes the feed channel to prevent dust from leaking out through the feed port when waste cartons are added.

[0041] Transmission mechanisms are symmetrically provided on both sides of the crushing bucket 2, so that the baffle 4 opens when the sealing cover 3 is closed on the upper side of the feed hopper to realize the opening and closing of the feed channel. When the sealing cover 3 is opened, the baffle 4 blocks the feed channel, and the dust in the crushing bucket 2 will not overflow through the feed channel. After the waste material is added, the sealing cover 3 is covered, and the baffle 4 is driven by the transmission mechanism to move during the falling process of the sealing cover 3, so that the feed channel is opened. At this time, the waste material slides into the material cavity of the crushing bucket 2 through the feed channel for crushing, which greatly reduces the amount of dust overflow when the waste material is added.

[0042] The transmission mechanism includes a gear 51, a ratchet 52, a guide rail 53 and a rack 54 that can move up and down along the guide rail 53. The gear 51 is connected to the end of the rotating shaft of the sealing cover 3, the ratchet 52 is connected to the end of the rotating shaft of the baffle 4, the guide rail 53 is arranged on both sides of the crushing bucket 2, and the upper half of the rack 54 is provided with a plurality of teeth that are arranged vertically equidistantly and meshed with the outer wall of the gear 51. The lower half of the rack 54 is provided with accommodating grooves 55 that are vertically equidistant. The internal rotation of the accommodating groove 55 is connected with a ratchet 56 to cooperate with the ratchet 52 and realize the opening of the baffle 4. The outer wall of the ratchet 56 is connected to the inner wall of the accommodating groove 55 by a torsion spring 57 to ensure that the ratchet 56 can automatically reset when the external force is lost. When the sealing cover 3 is opened, the gear 5 1 rotates and causes the rack 54 to move downward. During this process, the ratchet teeth 56 contact the outer wall of the ratchet wheel 52 and rotate, and then move to the bottom of the ratchet wheel 52. During this process, the ratchet wheel 52 will not drive the baffle plate 4 to rotate, that is, when the sealing cover 3 is opened, the baffle plate 4 blocks the feeding channel. When the sealing cover 3 is closed, the gear 51 rotates in the opposite direction and causes the rack 54 to move upward. At this time, the ratchet teeth 56 contact the ratchet wheel 52. Under the limit of the accommodating groove 55, the ratchet teeth 56 cannot rotate. At this time, the ratchet wheel 52 is pushed by the ratchet teeth 56 and rotates. At this time, the baffle plate 4 rotates to open the feeding channel. At this time, the newly added waste will enter the inner cavity of the crushing bucket 2 through the feeding channel for crushing, which greatly reduces the amount of dust overflow when adding waste.

[0043] Cylinders 22 are provided on both sides of the crushing bucket 2, and the output ends of the cylinders 22 are connected to the bottoms of both sides of the sealing cover 3, so as to realize the automatic opening or closing of the sealing cover 3.

[0044] A rotating disk 6 which can rotate along its central axis is provided on the support frame 1, and a motor which can drive the rotating disk 6 to rotate is provided at the bottom of the rotating disk 6, and the top of the rotating disk 6 is slidably connected to the bottom of the discharge port at the bottom of the crushing bucket 2 to form a bottom seal for the discharge port to prevent the crushed material from overflowing through the discharge port, and a plurality of accommodating cavities 7 are circumferentially opened at the top of the rotating disk 6 corresponding to the position of the discharge port at the bottom of the crushing bucket 2, and a receiving barrel 8 is placed in the accommodating cavity 7 to realize the recovery of shredded paper after crushing, and the receiving barrel 8 at different positions can be rotated to the bottom of the discharge port by rotating the rotating disk 6, so as to collect the crushed material without stopping the machine.

[0045] A rotating member 9 that can rotate along its central axis is provided on the top of the rotating disk 6. A plurality of rings 10 corresponding to the positions of the accommodating chambers 7 are provided on the outer wall of the rotating member 9. The rings 10 are sleeved on the outer walls of the tops of the other accommodating chambers 7 except the accommodating chamber 7 directly below the discharge port. A cylinder cover 11 is provided inside the ring 10 to cover the top of the receiving barrel 8. When the crushed waste is loaded into the receiving barrel 8, the rotating disk 6 rotates to make the receiving barrel 8 rotate to the bottom of the corresponding cylinder cover 11 to prevent the waste dust in the receiving barrel 8 from overflowing.

[0046] A number of limit blocks 81 are provided at intervals on the upper edge of the material receiving barrel 8, and a number of L-shaped clips 114 that cooperate with the limit blocks 81 are provided at the bottom of the barrel cover 11. The barrel cover 11 is rotated to align the clips 114 with the gaps between the limit blocks 81, and then the barrel cover 11 is pressed and rotated to make the clips 114 stuck under the limit blocks 81. At this time, the barrel cover 11 is tightly covered on the material receiving barrel 8, which is convenient for the subsequent transportation of the material receiving barrel 8.

[0047] The barrel cover 11 includes an upper plate 111 with a diameter larger than that of the receiving barrel 8 and a sealing convex plate 113 with a diameter matching the barrel mouth of the receiving barrel 8. A handle 112 is installed on the top of the upper plate 111, and a plurality of clamps 114 are arranged at intervals below the sealing convex plate 113. When the barrel cover 11 is closed on the receiving barrel 8, the sealing convex plate 113 seals the cavity of the receiving barrel 8, and the receiving barrel 8 can be taken out through the handle 112, so as to facilitate the unified collection and treatment of the crushed waste.

[0048] A support member 23 is provided on one side of the discharge slot of the crushing bucket 2. The side of the support member 23 away from the crushing bucket 2 abuts against the outer wall of one of the sleeve rings 10. The support member 23 supports the sleeve ring 10 to prevent the rotating member 9 from rotating at will.
