A waste compression mechanism 4 is arranged inside 32; the waste compression mechanism 4 includes a compression plate 42 which can slide back and forth along the inner wall of the collecting box 32, and the movement of the compression plate 42 is used to compress the crushed paper scraps in the collecting box 32, thereby improving the space utilization rate; the operating platform 1 is openly arranged corresponding to the opening position of the collecting bucket 31, and a movable plate 11 is installed at the open position of the operating platform 1 which can slide back and forth, and is used to open and close the opening of the collecting bucket 31, and a gear 51 meshing with the rack 22 is rotatably installed on the operating platform 1, and a disc 52 is coaxially connected to the gear 51, and the disc 52 rotates synchronously with the gear 51, and a connecting rod 53 is eccentrically hinged on the disc 52, and the other end of the connecting rod 53 is hinged to the movable plate 11; when the pressing plate 21 is pressed against the surface of the cardboard of the packaging box to be trimmed, the opening of the collecting bucket 31 is opened. In this embodiment, (1) only the outer surface of the lower end of the rack 22 is provided with meshing teeth that mesh with the gear 51, that is, the pressing plate 21 moves downward a certain distance to achieve the sliding of the movable plate 11 into place (removing the blocking of the opening of the collecting bucket 31 by the movable plate 11), and the subsequent further downward movement of the pressing plate 21 is mainly to achieve the pressing and limiting of the packaging box cardboard; (2) A slide groove is also provided on the inner side of the operating table 1 in the front and rear directions, and sliding parts are provided on both sides of the movable plate 11 to slide in the slide groove; (3) The movable plate 11 is respectively fixedly connected to the two sides of the movable plate 11, and the movable frame 12 is hinged to the connecting rod 53; (4) The upper surface of the operating table 1 can also be detachably installed with a decorative panel 8 for shielding the movable plate 11, which is used to cover the movable plate when the device is not in use to ensure the aesthetics of the operating table surface; (5) The lifting mechanism of the pressing plate 21 is a prior art and is not described in detail in the present utility model. For example, a hydraulic rod or an electric rod can be used to achieve its lifting movement.

[0022] Furthermore, a mounting plate 321 is provided at the bottom of the collection box 32, and a cylinder 41 is fixedly provided on the mounting plate 321. The protruding end of the cylinder 41 is connected to the compression plate 42, and is used to push the compression plate 42 to slide forward and backward. In this embodiment, a guide rod 43 is fixedly connected to the outer surface of the compression plate 42, and the guide rod 43 is coaxially arranged with the protruding end of the cylinder 41; the surface of the guide rod 43 is movably sleeved with a limiting cylinder 44, and the limiting cylinder 44 is fixedly installed on the mounting plate 321. In this embodiment, the guide rod 43 can play a role of limiting and guiding during the movement of the compression plate 42, so that the movement of the compression plate 42 is more stable, and the limiting cylinder 44 can guide and limit the guide rod 43.

[0023] Furthermore, a closing mechanism is provided on the outer side of the compression plate 42 , and the closing mechanism includes a blocking plate 61 that moves synchronously with the compression plate 42 and is used to temporarily block the connection between the collection bucket 31 and the collection box 32 .

[0024] Specifically, the connection structure between the blocking plate 61 and the compression plate 42 includes the following two implementations:

[0025] Embodiment 1: The blocking plate 61 and the compression plate 42 are integrally formed or fixedly connected in an L-shape to achieve synchronous sliding movement of the blocking plate 61 and the compression plate 42 so as to temporarily block the connection between the collection hopper 31 and the collection box 32 when the waste paper scraps are compressed.

[0026] Embodiment 2: The closing mechanism further includes a buffer spring 62, a fixed rod 63 and a long rod 64. The fixed rod 63 is fixed to the box body of the collection box. One end of the long rod 64 is fixed to the outside of the compression plate. The buffer spring 62 is sleeved on the long rod 64 and its two ends are respectively fixed to the compression plate and the blocking plate. The blocking plate is provided with a first sliding block 65 that is movably sleeved on the fixed rod 63. The bottom end of the blocking plate is provided with a second sliding block 66 that is sleeved on the long rod 64. One end of the buffer spring 62 is fixed to the second sliding block 66. In this embodiment, a baffle is provided on the side of the connection between the collection hopper 31 and the collection box 32 that is away from the cylinder 41 (or the pressure plate 21) or the side close to the stripping plate 13, which is used to limit the blocking plate 61 after it moves into place.

[0027] In actual use, when compressing paper scraps, the compression plate 42 moves in the direction close to the material return plate 13, and at the same time drives the long rod 64 to move. The long rod 64 drives the blocking plate 61 to move through the buffer spring 62. The fixed rod 63 can guide and limit the movement of the closing member, so that the movement of the blocking plate 61 is more stable and reliable. When the blocking plate 61 seals the paper scrap inlet (at this time, the blocking plate 61 is pressed against the baffle), the blocking plate 61 stops moving. At this time, the compression plate 42 continues to move forward, and the buffer spring 62 is stretched. The long rod 64 can support the blocking plate 61 in this process. After the sealing is completed, the paper scraps generated during the compression process can be prevented from falling to the position between the compression plate 42 and the cylinder 41, resulting in some paper scraps being unable to be compressed and difficult to clean.

[0028] like Figure 4 As shown, the outer surface of the compression plate 42 is connected to a blower, and a vent is provided on the surface of the compression plate 42 at a position corresponding to the blower 7, and the air outlet of the blower is connected to the vent. In this embodiment, under the action of the blower, after the waste paper scraps enter the collection box 32, the airflow enters the compression chamber through the vent, and blows the waste paper scraps to the side close to the material stripping plate 13, preventing the paper scraps from accumulating at the connection between the collection box 32 and the collection hopper 31, blocking the passage, and causing the waste paper scraps generated subsequently to be unable to enter the collection box 32 in time for compression processing.

[0029] In the present invention, a detachable stripping plate 13 is installed at one end of the collecting box 32 away from the compression plate 42. Specifically, a handle is arranged on the outer side of the stripping plate 13.

[0030] In the utility model, the surface of the movable plate 11 is fixedly connected with a rubber pad, which can play a buffering role when the movable plate 11 is reset.

[0031] The working principle of the utility model is as follows: when in use, the packaging box cardboard to be trimmed is placed at the trimming position of the trimming mechanism, the trimming mechanism is started, the pressing plate 21 automatically moves downward, driving the rack 22 to move downward, the rack 22 drives the gear 51 to rotate, the gear 51 rotates through the disc 52, and the disc 52 drives the connecting rod 53 to move, so as to realize the forward and backward sliding of the movable plate 11, so that the opening position of the collecting bucket 31 is in an open state; the pressing plate 21 continues to move downward until it is pressed against the surface of the cardboard to be trimmed to achieve the limit pressing of the pressing plate; then the trimming mechanism is used to complete the trimming function; the waste generated by the trimming falls into the collecting bucket 31, is crushed by the crushing roller 33, and the crushed waste enters the collecting box 32, and the crushed waste paper scraps can be blown into one side of the collecting box 32 by the blower, and then the cylinder 41 is started to push the compression plate 42 to slide relative to the inner wall of the collecting box 32 to realize the compression of the waste paper scraps. During the sliding process of the compression plate 42, the blocking plate 61 is driven to move synchronously to achieve the blocking of the connection between the collection bucket 31 and the collection box 32, to prevent the paper scraps from falling between the compression plate 42 and the cylinder 41 during the compression process. When the compression is completed, the cylinder 41 moves in the opposite direction, driving the compression plate 42 to reset, and the blocking plate 61 is synchronously reset in the opposite direction to release the blockage of the connection between the collection bucket 31 and the collection box 32; when it is necessary to clean the compressed waste material inside the collection box 32, the material removal plate 13 is disassembled to achieve the cleaning of the compressed paper scrap waste. The above technical solution solves the problem that due to the lack of an effective collection device, operators usually throw the cut scraps directly on the ground, and the accumulated waste paper will occupy a large space, making it difficult to collect the paper scraps, which may affect normal work.

[0032] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
