[0039] like Figures 1 to 4 As shown, this embodiment proposes a plate trimming and crushing machine, including a frame 1, a movable seat 2, a trimming knife 3 and a crushing mechanism 4; the movable seat 2 is movably arranged on the frame 1; the trimming knife 3 is arranged on the movable seat 2, and the trimming knife 3 cuts the plate to obtain a plate body and trimming; the crushing mechanism 4 is arranged on the movable seat 2, and is used to cut the trimming into pieces; the crushing mechanism 4 has a first crushing knife 41 and a second crushing knife 42, the first crushing knife 41 rotates, and a gap is formed between the second crushing knife 42 and the first crushing knife 42, and the gap is used for the trimming to pass through after crushing.

[0040] In this embodiment, the movable seat 2 is movably arranged on the frame 1, and the trimming knife 3 is arranged on the movable seat 2. The trimming knife 3 is used to trim the edges of the plate. When the movable seat 2 moves on the frame 1 with the trimming knife 3, the width of the trimming cut by the trimming knife 3 can be adjusted, thereby ensuring that the plate trimming and crushing machine provided by the present invention can cut trimmings of different widths and plates of different specifications; the crushing mechanism 4 is arranged on the movable seat 2, and can cut the trimming cut by the trimming knife 3 into smaller fragments, so as to facilitate the subsequent recycling and re-smelting. The crushing mechanism 4 includes a first crushing knife 41 and a second crushing knife 42. The first crushing knife 41 rotates, and the second crushing knife 42 rotates. The crushing knife 42 is fixedly arranged on the connecting seat. When the first crushing knife 41 rotates, it is approximately in contact with the second crushing knife 42. When the cut edge enters the side of the second crushing knife 42, the rotating first crushing knife 41 can cooperate with the second crushing knife 42 to cut the cut edge into pieces. In order to cut the slices to a better effect, multiple first crushing knives 41 can be provided, and the first crushing knives 41 are arranged in a circumferentially uniform form, so that the multiple first crushing knives 41 will cooperate with the second crushing knife 42 to cut the cut edge when rotating; using the rotating first crushing knife 41 and the fixed second crushing knife 42 can ensure that the cut edge is cut smaller.

[0041] The working principle of the plate trimming and crushing machine provided by the present invention is as follows: the plate passes through the frame 1 under the pulling force, and the waste edge of the plate is cut off from the plate after hitting the trimming knife 3 fixed on the moving seat 2, but because the back is still connected to the plate, the waste edge continues to move along the direction of movement of the plate until it hits the first crushing knife 41 and the second crushing knife 42 in the crushing mechanism 4, and then is cut into pieces by the first crushing knife 41 and the second crushing knife 42.

[0042] like Figure 1 to Figure 2 As shown, based on the same concept as the above-mentioned embodiment 1, a crushing mechanism 4 is further provided in this embodiment, and the crushing mechanism 4 also has a connecting body 43, a first knife seat 44 and a second knife seat 45; the connecting body 43 is arranged on the movable seat 2; the first knife seat 44 is rotatably arranged on the connecting body 43 and is used to install the first crushing knife 41; the second knife seat 45 is arranged on the connecting body 43 and is used to install the second crushing knife 42.

[0043] In this embodiment, the crushing mechanism 4 also includes a connecting body 43, a first knife seat 44 and a second knife seat 45. The connecting body 43 is fixedly set on the movable seat 2, the first knife seat 44 is rotatably set on the connecting body 43, and a platform is set, the platform is used to fix the first crushing knife 41, the second knife seat 45 is fixedly set on the connecting body 43, and the second crushing knife 42 is fixedly set on the second knife seat 45. After the plate is cut by the trimming knife 3, the trimming is continued to be transported until it encounters the first crushing knife 41 and the second crushing knife 42, and is cut into small pieces by the first crushing knife 41 and the second crushing knife 42.

[0044] like Figure 1 and Figure 3 As shown, based on the same concept as the above-mentioned embodiment 1, this embodiment also includes a first motor 6 and a first rotating shaft 7; the first motor 6 is arranged on the frame 1; the first rotating shaft 7 is rotatably arranged on the frame 1, one end of the first rotating shaft 7 is connected to the output shaft of the first motor 6, and the other end is connected to the first tool holder 44 and drives the first tool holder 44 to rotate.

[0045] In this embodiment, a first motor 6 and a first rotating shaft 7 are added to the plate trimming and crushing machine provided by the present invention. The first motor 6 is fixedly arranged on the frame 1, and the first rotating shaft 7 is rotatably arranged on the frame 1, and one end is connected to the output shaft of the first motor 6 through a coupling, and the other end is connected to the first knife seat 44. When the first motor 6 rotates, the first rotating shaft 7 rotates, thereby realizing the rotation of the first knife seat 44. This arrangement realizes that the first crushing knife 41 fixedly arranged on the first knife seat 44 can rotate at a high speed, and the trimming can be easily shredded.

[0046] like Figure 1 to Figure 2 As shown, based on the same concept as the above-mentioned embodiment 1, this embodiment further proposes a crushing mechanism 4, and the crushing mechanism 4 also has a guide plate 46, which is arranged on the frame 1, and the guide plate 46 has a discharge end, and the discharge end has a bearing surface 461 and a guide surface 462, and the bearing surface 461 and the guide surface 462 are arranged at an angle, the bearing surface 461 is used to contact the cutting edge, and the guide surface 462 faces the second crushing knife 42.

[0047] In this embodiment, the crushing mechanism 4 also includes a guide plate 46, which is fixedly arranged on the frame 1, and the discharge end of the guide plate 46 has a bearing surface 461 and a guide surface 462 at a certain angle. The bearing surface 461 is parallel to the surface on the frame 1 and is used to carry the cut edge, that is, the bottom of the cut edge is in contact with the bearing surface 461, and the guide surface 462 is facing the tip of the second crushing knife 42. In this way, it can be ensured that the cut edge will be hit by the first crushing knife 41 when encountering the first crushing knife 41, and then the cut edge will bend and stick to the guide surface 462, and enter from the guide surface 462 to between the first crushing knife 41 and the second crushing knife 42 for shredding.

[0048] Based on the same concept as the above-mentioned embodiment 1, this embodiment further proposes that the material guide plate 46 is rotatably disposed on the frame 1 and can be locked.

[0049] In this embodiment, in order to ensure that the cutting edge can smoothly enter between the first crushing knife 41 and the second crushing knife 42, the guide plate 46 can be rotatably set on the frame 1. The rotation setting is in the form of a through hole on the guide plate 46, and a threaded hole on the frame 1. The guide plate 46 is fixed to the frame 1 by bolt connection, and the guide plate 46 is pressed onto the frame 1 by bolts. This setting method can not only realize the rotation setting form of the guide plate 46 on the frame 1, but also realize the locking of the guide plate 46 after rotating a certain angle.

[0050] like Figure 1 As shown, based on the same concept as the above-mentioned embodiment 1, this embodiment also includes a material collecting vehicle 5, and the crushing mechanism 4 also has a material guide plate 47, which is arranged on the connecting body 43 and located below the second crushing knife 42, and one end of the material guide plate 47 extends into the interior of the material collecting vehicle 5.

[0051] In this embodiment, the crushing mechanism 4 also includes a guide plate 47, which is fixedly arranged on the connecting body 43 and is located below the second crushing knife 42, so that the cut edges chopped by the first crushing knife 41 and the second crushing knife 42 can fall onto the guide plate 47. The guide plate 47 is tilted on the frame 1, and the bottom end extends into the aggregate truck 5, so that the chopped cut edges can enter the aggregate truck 5 from the guide plate 47 under their own weight, thereby completing the collection of the chopped cut edges.

[0052] like Figure 1 and Figure 3 As shown, based on the same concept as the above-mentioned embodiment 1, this embodiment also includes a second motor 8 and a second rotating shaft 9; the second motor 8 is arranged on the frame 1; the second rotating shaft 9 is rotatably arranged on the frame 1, and the second rotating shaft 9 is connected to the output shaft of the second motor 8, the second rotating shaft 9 has an external thread, and the movable seat 2 has an internal thread, and the second rotating shaft 9 and the movable seat 2 realize screw transmission by means of a threaded connection.

The second rotating shaft 9 has an external thread, and a threaded hole is provided at the bottom of the movable seat 2. The second rotating shaft 9 is penetrated into the threaded hole and is threadedly connected with the connecting seat. When the second motor 8 drives the second rotating shaft 9 to rotate, the second rotating shaft 9 rotates, and the connecting seat moves along the axial direction of the second rotating shaft 9, that is, a screw transmission can be realized between the second rotating shaft 9 and the connecting seat. Such a setting not only realizes the movement of the movable seat 2 on the frame 1, but also reduces the complexity of the entire device.

[0054] like Figure 3 As shown, based on the same concept as the above-mentioned embodiment 1, this embodiment further includes a handle 10 , and the handle 10 is arranged on the second rotating shaft 9 .

[0055] In this embodiment, a handle 10 is further provided in the plate trimming and crushing machine provided by the present invention.

There are two moving seats 2, and both of them realize the form of screw transmission with the second rotating shaft 9. Since the edges on both sides of the plate need to be cut, the moving seats 2 are set on both sides of the plate. In order to realize the two moving seats 2 to be relatively close or far away, the external thread on the second rotating shaft 9 can be set into two sections, and the thread directions at both ends are different. The moving seat 2 is provided with threaded holes with different thread directions, so that the operation of moving the moving seat 2 to be relatively close or far away can be realized, and such a setting form can improve the adjustment rate of the position of the moving seat 2.

[0058] like Figure 3As shown, based on the same concept as the above-mentioned embodiment 1, this embodiment also proposes that the frame 1 includes a base 11, a support frame 12 and a roller 13; the trimming knife 3 and the crushing mechanism 4 are arranged on the base 11, and the support frame 12 is arranged on the base 11; the roller 13 is rotatably arranged on the support frame 12, and the support frame 12 and the roller 13 are placed between two movable seats 2.
