[0002] 3D printing, also known as additive manufacturing technology, is a technology that manufactures physical parts by adding materials layer by layer based on three-dimensional CAD data. 3D printing technology is divided into seven categories, including binder jetting, directed energy deposition, material extrusion, material jetting, powder bed fusion, sheet lamination and v-photopolymerization. However, if a 3D printer fails to print a product, the failed product will be called solid waste. Such solid waste is generally thrown away directly, but this operation will cause a waste of resources, so recycling equipment is needed to re-melt the above solid waste for recycling.

[0040] Embodiment 2, based on embodiment 1, Figures 1 to 11It is given that the anti-shift lock unit includes a positioning square groove 15 arranged in the positioning square column 6, and the side of the positioning square groove 15 close to the filter square plate 4 passes through the top of the positioning square column 6; a positioning square plate 16 is slidably arranged in the positioning square groove 15, and the side away from the filter square plate 4 is connected to one end of an extrusion spring 17, and the other end of the extrusion spring 17 is fixedly connected to the inner bottom surface of the positioning square groove 15; a retaining square column 18 is also slidably arranged in the positioning square groove 15, and one end of the retaining square column 18 is fixedly connected to the side of the filter square plate 4 close to the positioning square column 6, and the other end of the retaining square column 18 is in contact with the positioning square plate 16; A locking bevel groove 19 is also provided on the side of the retaining square column 18; a locking square box 20 is also installed on the side of the positioning square column 6, and the locking square box 20 is connected to the positioning square groove 15, and the locking square box 20 and the locking bevel groove 19 are on the same side; two locking slide bars 21 are symmetrically arranged in the locking square box 20, and the end of the locking slide bar 21 away from the positioning square column 6 passes through the locking square box 20 and is connected to a locking limit plate; the end of the locking slide bar 21 close to the positioning square column 6 is connected to a locking bevel block 22, and the inclined surface area of ​​the locking bevel block 22 is located in the positioning square groove 15 and the inclined surface faces the retaining square column 18 away from the filter square plate 4; a locking spring 23 is sleeved on the locking slide 21, one end of the locking spring 23 is connected to the locking bevel block 22, and the other end is connected to the inner wall of the locking square box 20; a locking square box 20 is also installed on the side of the positioning square column 6, the locking square box 20 is connected to the positioning square groove 15, and the locking square box 20 and the locking bevel groove 19 are on the same side; two locking slides 21 are symmetrically arranged in the locking square box 20, and the end of the locking slide 21 away from the positioning square column 6 passes through the locking square box 20 and is connected to the locking limit plate; the end of the locking slide 21 close to the positioning square column 6 is connected to the locking bevel block 2 2, the inclined surface area of ​​the locking bevel block 22 is located in the positioning square groove 15 and the inclined surface faces the end of the retaining square column 18 away from the filter square plate 4; the locking slide bar 21 is sleeved with a locking spring 23, one end of the locking spring 23 is connected to the locking bevel block 22, and the other end is connected to the inner wall of the locking square box 20; the locking bevel block 22 is also provided with a plurality of triggering round wheels 39 on the side away from the locking slide bar 21, and the triggering round wheels 39 are connected with an auxiliary substrate 40, and the auxiliary substrate 40 is fixedly arranged on the side of the locking bevel block 22 away from the locking slide bar 21; the locking bevel groove 19 is located on the moving path of the locking bevel block 22;

[0041] When the device is in use, the retaining square column 18 on the filter square plate 4 is aligned with the positioning square groove 15 on the positioning square column 6 and moved, so that the retaining square column 18 is limited and moved in the positioning square groove 15, so that the retaining square column 18 contacts the positioning square plate 16, so that it is also limited and moved in the positioning square groove 15, and the extrusion spring 17 is in a buffering state, and then the end point of the retaining square column 18 contacts the inclined surface of the locking bevel block 22, and under the action of the force, the locking bevel block 22 moves horizontally, so that it moves relative to the locking square box 20 through the locking slide bar 21, so that the locking spring 23 is in a buffering state. The locking bevel 22 is in a buffering state until the retaining square column 18 moves to the bottom of the positioning square groove 15, so that the locking bevel block 22 and the locking bevel groove 19 are at the same height, so that the locking bevel block 22 is no longer limited, and the locking bevel block 22 is reset and moved by the reset of the locking spring 23 to enter the locking bevel groove 19. At this time, the filter square plate 4 is no longer pressed, so that the extrusion spring 17 is no longer subjected to the force to reset, so that the right-angled surface of the locking bevel groove 19 and the locking bevel block 22 contact and strengthen the friction between the two, so that the locking bevel block 22 clamps the retaining square column 18 and fixes it when When the filter plate 4 needs to be removed, the locking slide bar 21 only needs to be pulled outward, so that the locking bevel block 22 is no longer in contact with the locking bevel groove 19, thereby releasing the limit setting of the retaining square column 18, so that the extrusion spring 17 is reset and moved to eject the filter plate 4, thereby completing the removal operation of the filter plate 4. The installation and removal operations of the filter plate 4 are convenient and fast, and can be completed without the aid of any tools, which reduces the limitations of the equipment when in use and improves the loading and unloading efficiency of the filter plate 4, making it easy to It can be maintained, replaced or cleaned so that the operator can choose the appropriate type of filter square plate 4 according to the actual usage, thereby improving the use effect of the equipment; it is worth mentioning that when the locking spring 23 is in the buffering state, it means that the locking bevel 22 moves laterally, so that several trigger wheels 39 on the side close to the retaining square column 18 contact with the side of the retaining square column 18, reducing the friction between the retaining square column 18 and the locking bevel 22, improving the stability of the filter square plate 4 during loading and unloading, avoiding the shaking of the filter square plate 4, and improving the recovery effect of the equipment.

[0042] Embodiment 3, based on embodiment 1, Figures 1 to 11It is given that the slow-descent energy concentrator includes a positioning spring 24, which is located in the positioning square cylinder 5; one end of the positioning spring 24 is fixedly connected to the end of the positioning square column 6 away from the filter square plate 4, and the other end of the positioning spring 24 is fixedly connected to the inner wall of the positioning square cylinder 5; an energy concentrating cylinder 25 is also installed on the side of the positioning square cylinder 5, and the interior of the energy concentrating cylinder 25 is connected to the interior of the positioning square cylinder 5; a guide round block 26 is slidably arranged in the energy concentrating cylinder 25, and a buffer pad is also provided on the side of the guide round block 26 close to the positioning square cylinder 5 27; the inner bottom surface of the energy-gathering cylinder 25 is also connected to a pressure sensor 28; an energy-gathering spring 35 is also arranged in the energy-gathering cylinder 25, one end of the energy-gathering spring 35 is connected to the pressure sensor 28, and the other end is connected to a T-shaped square plate 36, and the T-shaped square plate 36 is arranged on the side of the guide round block 26 close to the pressure sensor 28; an electric telescopic rod 37 is installed on both sides of the T-shaped square plate 36, and a rubber round wheel 38 is installed on the output end of the electric telescopic rod 37, and the rubber round wheel 38 is in contact with the inner wall of the energy-gathering cylinder 25;

[0043] When the solid waste becomes particles after being crushed, it will fall on the filter square plate 4, so that the positioning square column 6 on the filter square plate 4 moves within the positioning square tube 5, so that the positioning spring 24 is in a buffering state. The buffering force brought by the positioning spring 24 can prevent the impact force generated by the impact when the particles fall on the filter square plate 4, which may cause the particles to break or cause damage to the filter square plate 4. This not only improves the service life of the equipment, but also makes the forming degree of the crushed particles more uniform. At the same time, even if solid waste that is not completely crushed, that is, larger particles, is encountered, due to The larger its own weight, the greater the energy it hits on the filter square plate 4, which makes the positioning spring 24 deformed to a greater extent, so that the gas in the positioning square cylinder 5 enters the energy-gathering cylinder 25 and acts on the guide round block 26. The buffer pad 27 provided can further absorb the above-mentioned strong impact energy, and at the same time, the guide round block 26 moves within the energy-gathering cylinder 25, so that the energy-gathering spring 35 is in a buffer state. The multi-stage buffer is further reduced by the impact energy generated by larger particles to avoid serious damage to the equipment. At the same time, the energy-gathering spring 35 is in a buffer state. The energy value is also recorded by the pressure sensor 28. Through the analysis of the controller, it is known that when the energy-gathering spring 35 is in a buffer state for a moment, that is, when the value increases in a moment, it means that the filter square plate 4 encounters a large particle falling. When the value decreases from the maximum, it means that the energy-gathering spring 35 is about to reset. The controller sends a signal to the electric telescopic rod 37, so that its output end drives the rubber round wheel 38 to move, so that it fits with the inner wall of the energy-gathering cylinder 25, thereby increasing the friction between the guide round block 26 and the energy-gathering cylinder 25, so that the movement of the guide round block 26 The speed is reduced, and the specific resetting movement speed is implemented according to the force condition of the filter square plate 4, which makes it impossible for the gas in the positioning square tube 5 to reset, and makes it impossible for the filter square plate 4 to reset and move quickly after the impact force disappears, so as to avoid the strong stored elastic potential energy causing the filter square plate 4 to reset in an instant and cause the larger particles on it to fly up and hit the equipment or continue to hit the filter square plate. By controlling the resetting movement speed of the filter square plate 4, the above phenomenon can be avoided, thereby increasing the service life of the equipment and preventing larger particles from hitting the equipment and causing it to shake, thereby improving the recovery effect and efficiency of the equipment.
