[0001] The utility model relates to the technical field of 3D printing, in particular to a waste moving mechanism and a 3D printer. Background Art

[0002] In a 3D printer capable of multi-color printing, consumables of different colors are connected to their respective extruders and then introduced into the consumable channels of the print head. When replacing the consumables, the original consumables are cut between the melting section and the non-melting section in the consumable channel, the un-melted original consumables are drawn out, and then new consumables are conveyed. After the consumable replacement is completed, the original consumables remaining in the consumable channel need to be extruded, and then new consumables are used for printing, so as to ensure the accuracy of the model.

[0003] In the prior art, the consumables extruded by the print head usually accumulate at the same position. As the extruded consumables increase, the moving range of the print head is affected, and the consumables are easily rolled down or blown off to the printing platform by the air flow, affecting normal printing.

[0022] To further elaborate on the technical means and effects adopted by the present utility model to achieve the intended utility model purpose, the following, in conjunction with the accompanying drawings and preferred embodiments, details the specific optional implementation manners, structures, features and their effects of the waste material moving mechanism proposed according to the present utility model.

[0023] On the one hand, as Figure 1-8 shown, an embodiment of the present utility model provides a waste material moving mechanism, including:

[0024] A main body 100;

[0025] A conveyor belt 200, the conveyor belt 200 includes a receiving area, and the position of the receiving area includes a receiving position and a discharging position. When the receiving area is in the receiving position, the receiving area receives the waste material 20;

[0026] An acting component 300, the acting component 300 is connected to the main body 100, the conveyor belt 200 is connected to the acting component 300, and the acting component 300 is at least used to drive the conveyor belt 200 so that the receiving area moves from the receiving position to the discharging position, so that the waste material 20 falls off.

[0027] The waste moving mechanism is used for receiving and discharging the waste consumables of the 3D printer. The 3D printer mainly includes a base, a gantry mechanism, an X-axis mechanism, a printing platform and a print head. The printing platform is connected to the base, the gantry is connected to the base, the X-axis mechanism is connected to the gantry mechanism, the print head is connected to the X-axis mechanism, and the print head is located above the printing platform. The gantry mechanism is used to drive the X-axis mechanism to move, so that the print head approaches or moves away from the printing platform. The X-axis mechanism is used to drive the print head to move in the X-axis direction, and the base is used to drive the printing platform to move in the Y-axis direction, thereby realizing the relative movement of the print head and the printing platform in the three directions of X-Y-Z. The main body 100 plays the role of supporting the component 300 and the conveyor belt 200. During assembly, the relative position of the main body 100 and the 3D printer is fixed, and it can be directly fixed on the 3D printer, such as being bolted to at least one of the X-axis mechanism, the gantry mechanism and the base. Alternatively, the main body 100 can be supported and fixed by an additional fixing structure. The position of the main body 100 satisfies that at least part of the conveyor belt 200 corresponds to the moving area of the print head, that is, the print head can move above the conveyor belt 200. To minimize the printing space occupied by the waste moving mechanism, when the print head moves to the conveyor belt 200 to extrude waste, the print head is located at the extreme position in the X-axis direction.

[0028] The conveyor belt 200 can be conveyor belts 200 of various materials and structures, as long as it has a certain supporting force and can be bent. For example, it can be soft rubber, cloth, crawler, etc. The conveyor belt 200 can be arranged in a loop and move by rolling. For example, two rollers are provided, and the conveyor belt 200 is wound around the two rollers, and the conveyor belt 200 moves by the same-direction rolling of the two end rollers. The acting component 300 can be actively driven. For example, the acting component 300 includes a motor and a transmission device. The transmission device includes the aforementioned two rollers. The motor is connected to the main controller of the 3D printer. After the main controller controls the print head 30 to eject the waste 20, it controls the motor to actively move the transmission device, and then drives the conveyor belt 200 to move to discharge the waste 20. Alternatively, the acting component 300 can also be moved under an external force to drive the conveyor belt 200, and the acting component 300 only plays a transmission role. For example, part of the structure of the acting component 300 can be moved under the action of the print head 30, and then drive the conveyor belt 200 to move.

[0029] When the receiving area is at the receiving position, the surface of the receiving area can be a flat surface or an arc surface. For example, in the foregoing embodiment including two rollers, the receiving area is located between the two rollers. Alternatively, other support structures may be provided between the two rollers, so that the area of the conveyor belt 200 between the two rollers has a certain undulation, which can be an arc or an inclined surface, and the receiving area is the arc or inclined surface area between the two rollers. Since the waste 20 has a certain temperature when it is extruded, it will solidify on the conveyor belt 200 or the receiving area. After the conveyor belt 200 receives the waste 20 and moves, the waste 20 is separated. The waste 20 can be separated from the conveyor belt 200 by bending the receiving area or a greater degree of bending. For example, the conveyor belt 200 drives the waste 20 to move to one side roller, and the position where the receiving area is connected to the waste 20 will change according to the shape of the roller. The receiving area is bent to a greater degree, while the deformation degree of the waste 20 is limited, and then the waste 20 actively separates from the conveyor belt 200 and falls off at the end of the roller or the conveyor belt 200 and is thrown out. Alternatively, a force-applying structure can also be provided, and an external force is applied to the waste 20 through the force-applying structure to promote the waste 20 to separate from the receiving area. During the movement of the conveyor belt 200 driving the waste 20, the waste 20 interferes with the force-applying structure and then separates. The force-applying structure can be an additional knife shovel, or it can be a part of the main body 100. The force-applying structure can interfere with the waste 20 at any position before the waste 20 moves to the end of the conveyor belt 200, and then the waste 20 separates from the conveyor belt 200 in advance and then falls off at the end of the conveyor belt 200. Alternatively, it can also interfere with the waste 20 at the end of the conveyor belt 200 or before the conveyor belt 200 drives the waste 20 to move to the position where the waste 20 faces downward. Then, after the waste 20 separates from the conveyor belt 200, it immediately falls. The end of the foregoing conveyor belt 200 refers to the position where the conveyor belt 200 bends and changes the extension direction, such as the position corresponding to the outermost end of the roller on the conveyor belt 200.

[0030] A waste moving mechanism and a 3D printer proposed in an embodiment of the present utility model mainly drive a conveyor belt to move through an acting component, and then move and discharge consumables, so as to avoid the accumulation of consumables, avoid affecting the moving range of the print head, and avoid the consumables rolling onto the printing platform. In the prior art, the consumables extruded by the print head usually accumulate at the same position. As the extruded consumables increase, it affects the moving range of the print head, and the consumables are easily rolled or blown off by the air flow onto the printing platform, affecting normal printing. Compared with the prior art, in this application document, when the consumables need to be replaced, the print head moves to face the conveyor belt and extrudes the waste onto the conveyor belt. Then, the acting component drives the conveyor belt actively or under the action of an external force, and the conveyor belt moves, and the waste will be driven to move until it separates from the conveyor belt. On the one hand, it avoids the accumulation of materials occupying the printing space. On the other hand, after the materials fall off, they can fall within a specified range, avoiding the uncontrollable rolling of the materials or the floating caused by the air flow, and then avoiding the materials falling into the printing area and the printing platform and affecting the printing process.

[0031] In an optional embodiment, the acting component 300 is used to drive the conveyor belt 200 to move in a single direction. The number of receiving areas is multiple.

[0032] During the process of receiving and discharging the waste 20 multiple times, the conveyor belt 200 only rolls in a single direction. Taking Figure 8 the direction as an example, the conveyor belt 200 only rolls in the clockwise direction. In each cycle of receiving the waste 20, the receiving area will change compared with the previous time. For example, when the conveyor belt 200 receives the waste 20 this time, the receiving area is a partial area of the current conveyor belt 200 corresponding to the print head 30. Then the conveyor belt 200 moves to discharge the waste, and the waste 20 separates from the conveyor belt 200. Then the conveyor belt 200 remains stationary until the next time the print head 30 needs to spray material, and the receiving area is a partial area of the current conveyor belt 200 corresponding to the print head 30, that is, the position of the receiving area on the conveyor belt 200 has changed.

[0033] In another optional embodiment, the number of receiving areas is one, and the acting component 300 is used to drive the receiving area to reciprocate between the receiving position and the discharging position.

[0034] During the process of receiving and discharging the waste 20 multiple times, the position of the receiving area on the conveyor belt 200 is fixed. As Figure 1-5 shown, when the receiving area is at the receiving position, it receives the waste 20. Then the conveyor belt 200 rolls clockwise in the Figure 8 shown direction, and the receiving area moves to the discharging position. As Figure 8 shown, since the receiving area moves to the roller, the bending degree of the receiving area changes, and the waste 20 separates from the conveyor belt 200. Then the conveyor belt 200 is in the Figure 8Counterclockwise rolling in the indicated direction causes the receiving area to return to the receiving position again, waiting for the print head 30 to spray material next time.

[0035] In the following embodiments, taking the number of the receiving position and the throwing position as one for example, the features in the following embodiments can also be selectively applied to the cases where the number of the receiving position and the throwing position is multiple.

[0036] In an alternative embodiment, the degree of bending of the receiving area when it is at the throwing position is greater than that when the receiving area is at the receiving position, so that the waste material 20 can be separated.

[0037] When at the receiving position, the receiving area is located between two rollers and thus is approximately planar, and the bottom surface of the waste material 20 in contact with the receiving area is also planar. When at the throwing position, the receiving area is located at one end of the roller, making the receiving area approximately arc-shaped in bending, and the waste material 20 cannot achieve such a degree of bending and thus actively falls off from the receiving area.

[0038] In another alternative embodiment, the main body 100 includes a stripping plate 111. When the receiving area is at the throwing position, the stripping plate 111 is opposite to the receiving area, and the stripping plate 111 is used to act on the waste material 20 to separate the waste material 20 from the conveyor belt 200.

[0039] The aforementioned force application structure may include a stripping plate 111. When the receiving area moves to the throwing position, the stripping plate 111 will act on the waste material 20, and then push or peel off the waste material 20 from the conveyor belt 200. It can be used in combination with the embodiment where the bending degree of the receiving area is greater when the receiving area is at the throwing position, that is, the stripping plate 111 corresponds to the roller. When the conveyor belt 200 drives the waste material 20 to move to the roller, the conveyor belt 200 will bend, and then the waste material will be peeled off passively on the front side in the moving direction, forming an opening between the waste material 20 and the conveyor belt 200. As the conveyor belt 200 continues to move, the stripping plate 111 will penetrate into the opening, and then scoop up the waste material 20 from between the bottom surface of the waste material 20 and the conveyor belt 200 to assist in the separation of the waste material 20.

[0040] In an alternative embodiment, the stripping plate 111 is in sliding contact with the conveyor belt 200 or has a preset gap therebetween. For example, there is a gap between 0.1 millimeter and 1 millimeter between the stripping plate 111 and the conveyor belt 200, so as to ensure that the stripping plate 111 can extend between the bottom surface of the waste material 20 and the conveyor belt 200 while avoiding the driving burden of the conveyor belt 200 caused by the friction between the stripping plate 111 and the conveyor belt 200 and avoiding the wear of the conveyor belt 200 by the stripping plate 111.

[0041] In one implementation, the top end of the stripper plate 111 is used to act on the waste 20. The stripper plate 111 includes an acting inclined surface, which is located on the side of the stripper plate 111 opposite to the conveyor belt 200. The acting inclined surface reduces the thickness of the stripper plate 111 in the direction close to the top end.

[0042] The acting inclined surface makes the top end of the stripper plate 111 thinner, which helps the stripper plate 111 to extend between the bottom surface of the waste 20 and the conveyor belt 200, and avoids the problem that the stripper plate 111 is too wide and gets stuck with the waste 20. The acting inclined surface makes the relative movement between the stripper plate 111 and the waste 20 smoother.

[0043] In an alternative implementation, the waste moving mechanism further includes: a push plate 400, which is connected to the conveyor belt 200, and the push plate 400 is located on the side of the receiving area away from the throwing position.

[0044] Take Figure 8 As shown in the figure, after the waste 20 falls into the receiving area, the receiving area drives the waste 20 to move to the right. The push plate 400 is located on the left side of the receiving area and is arranged adjacent to the receiving area. On the one hand, it can prevent the waste from rolling backward due to unstable connection with the conveyor belt 200 during the movement of the waste 20, resulting in the problem of inability to throw the waste. On the other hand, when the waste 20 moves to the stripper plate 111, the stripper plate 111 and the push plate 400 act on the waste 20 in two opposite directions respectively, which can assist the stripper plate 111 in peeling the waste 20.

[0045] In an alternative implementation, the acting component 300 includes a force-applying component and a first force-applying member 310. The force-applying component is at least connected to the conveyor belt 200, and the force-applying component is used to move under an external force to drive the receiving area to move from the throwing position to the receiving position. The first force-applying member 310 is at least connected to the conveyor belt 200 and / or the force-applying component, and the first force-applying member 310 is used to drive the receiving area to move from the receiving position to the throwing position.

[0046] The manner of applying an external force can be various. For example, an additional driving device can be provided, or an external force can be applied to the force application component by means of the movement of the print head 30. When the print head 30 ejects the waste material 20, the print head 30 moves towards the receiving area, then approaches the force application component, pushing at least part of the structure of the force application component to move, and then driving the receiving area to move to the receiving position. The first force application member 310 can be in various forms. The first force application member 310 can be a structure capable of being temporarily connected to the print head 30, such as magnetic connection or adsorption connection. The first force application member 310 can be connected to the force application component. When the print head 30 acts on the force application component, it will be connected to the first force application member 310 at the same time. Then, when the print head 30 ejects the waste material 20 and moves away from the receiving area, the first force application member 310 will be driven by the print head 30, and then drive part of the structure of the force application component or the receiving area to move to the throwing position. Or, in an alternative embodiment, the first force application member 310 can be an energy storage member, such as an elastic member, such as a spring, foam, soft rubber, etc., which can be a tension spring, torsion spring, compression spring, etc. During the process of the print head 30 applying an external force to the force application component to move the receiving area to the receiving position, the elastic member is stretched and stores energy, or the elastic member can also be compressed and store energy. After the print head 30 extrudes the waste material 20 and moves away from the force application component, the elastic member drives the force application component or the conveyor belt 200 to move, so that the receiving area moves to the throwing position. During this process, the elastic member releases energy. The elastic member also plays a role in stabilizing the receiving area at the throwing position.

[0047] In an alternative embodiment, in the above-described embodiment where two rollers are provided and the conveyor belt 200 is wound around the two rollers, the force application component can be directly connected to the conveyor belt 200. In this embodiment, the force application component can be a single rod-shaped structure. One end of the force application component is connected to the conveyor belt 200, and the other end is used for the print head 30 to apply force.

[0048] Or, in another alternative embodiment, the force application component includes a second force application member 320 and a transmission component 330. The second force application member 320 is connected to the transmission component 330, and the transmission component 330 is connected to the conveyor belt 200. The second force application member 320 is used to move under the action of an external force to drive the conveyor belt 200 to move through the transmission component 330.

[0049] By providing the transmission component 330, on the one hand, the structure of the transmission component 330 can be set to make the conveyor belt 200 receive force more evenly, avoiding the problem that the conveyor belt 200 is easily deformed due to uneven force when a single second force application member 320 is directly connected to the conveyor belt 200. On the other hand, the distance ratio between the movement of the second force application member 320 and the conveyor belt 200 can be adjusted to increase the movable distance of the conveyor belt 200.

[0050] In one implementation, the second force-applying member 320 moves in a direction opposite to the moving direction of the receiving area, so that the receiving area can move in the opposite direction to the print head 30. It can be realized that when the print head moves outward of the 3D printer, the receiving area is pushed inward of the 3D printer, and then moves to face the print head; and when the print head moves toward the printing area or the inside of the 3D printer, the receiving area moves outward of the 3D printer and ejects the waste material 20.

[0051] In the following, a specific structure of a transmission assembly 330 will be exemplified. It can be understood that the transmission assembly 330 is not limited thereto: In an alternative implementation, the transmission assembly 330 includes a linkage belt 331, a first roller assembly, and a second roller assembly. The first roller assembly and the second roller assembly are arranged at intervals and are both rotatably connected to the main body 100. The conveyor belt 200 is wound around the first roller assembly and the second roller assembly, and the linkage belt 331 is wound around the first roller assembly and the second roller assembly. The second force-applying member 320 is connected to the linkage belt 331. The second force-applying member 320 is used to drive the linkage belt 331 to move, and then drive the first roller assembly and the second roller assembly to rotate, driving the conveyor belt 200 to move.

[0052] The conveyor belt 200 and the linkage belt 331 can be the same transmission belt, such as a transmission belt with teeth provided on the inner circle. The width of the linkage belt 331 can be smaller than that of the conveyor belt 200, thereby reducing the occupied space. The first roller assembly and the second roller assembly are arranged in parallel at intervals and serve as two rollers supporting the conveyor belt 200 and the linkage belt 331. In one implementation, the second force-applying member 320 is connected to the lower layer of the linkage belt 331, or is connected to the area of the linkage belt 331 that is located below during use. The receiving area is located on the upper layer of the conveyor belt 200, or the receiving area is a partial area of the conveyor belt 200 that is located above during use, so that the moving direction of the second force-applying member 320 is opposite to that of the receiving area. The moving directions of the conveyor belt 200 and the linkage belt 331 are the same. Taking Figure 8 the direction shown as an example, when it is necessary to eject the waste material 20, the second force-applying member 320 moves leftward under the action of the print head 30, the linkage belt 331 rolls counterclockwise, and the conveyor belt 200 also rolls counterclockwise, so that the receiving area moves leftward. After the print head 30 ejects the waste material 20, the print head 30 moves rightward, and the second force-applying member 320 moves rightward following the print head 30 under the action of the first force-applying member 310. The linkage belt 331 rolls clockwise, and the conveyor belt 200 also rolls clockwise, so that the receiving area moves rightward, moves outward of the 3D printer, and ejects the waste material 20.

[0053] In an alternative embodiment, at least one of the first roller assembly and the second roller assembly includes a rotating shaft 332, a first synchronous pulley 333, and a second synchronous pulley 334. The rotating shaft 332 is rotatably connected to the main body 100. The first synchronous pulley 333 and the second synchronous pulley 334 are coaxially connected to the rotating shaft 332 and circumferentially limited. The first synchronous pulley 333 is connected to the linkage belt 331, and the second synchronous pulley 334 is connected to the conveyor belt 200.

[0054] The structures of the first roller assembly and the second roller assembly may be the same. In an alternative embodiment, both the first synchronous pulley 333 and the second synchronous pulley 334 have teeth. The first synchronous pulley 333 meshes with the linkage belt 331, and the second synchronous pulley 334 meshes with the conveyor belt 200. The pitch diameter of the outer circle of the teeth of the second synchronous pulley 334 is greater than that of the first synchronous pulley 333. Then, when the first synchronous pulley 333 and the second synchronous pulley 334 rotate synchronously, since the pitch diameter of the outer circle of the teeth of the second synchronous pulley 334 is larger, the linear velocity of the conveyor belt 200 driven is greater, and the conveyor belt 200 will move a longer distance compared to the linkage belt 331. Then, the waste material 20 is transported over a longer distance, and the distance that the print head 30 pushes the second force application member 320 to move is reduced, the energy consumption is reduced, and the efficiency is improved.

[0055] In an alternative embodiment, at least one of the first roller assembly and the second roller assembly further includes a bearing 335. The rotating shaft 332 is rotatably connected to the main body 100 through the bearing 335.

[0056] There may be four bearings 335, which are respectively connected to both ends of the two rotating shafts 332. As Figure 7 shown, four bearing seats 112 are provided on the main body 100. The inner ring of the bearing 335 is connected to the rotating shaft 332, such as by interference fit. The outer ring of the bearing 335 is connected to the bearing seat 112, thus ensuring smooth rotation of the first roller assembly and the second roller assembly.

[0057] In the embodiment where the first force application member 310 is an elastic member, in an alternative embodiment, the force application assembly includes a first connecting column 340. The main body 100 includes a second connecting column 130. Both ends of the elastic member are respectively sleeved on the first connecting column 340 and the second connecting column 130. If the elastic member is a tension spring, both ends of the elastic member are respectively bent into rings, thus facilitating the disassembly and assembly of the elastic member. The first connecting column 340 may be connected to the aforementioned second force application member 320, such as being integrally formed with the second force application member 320. In addition, the connection between the elastic member and the force application assembly and the main body 100 may also be other detachable connection methods, such as plugging, clamping, holding, bonding, welding, etc.

[0058] In an optional implementation, the second force applying member 320 is slidably connected to the main body 100 to ensure the stability of the movement of the second force applying member 320 , and the main body 100 plays a guiding role in the movement of the second force applying member 320 .

[0059] There may be many ways of sliding connection. For example, in an optional embodiment, a sliding opening 101 is provided on one of the main body 100 and the second force-applying member 320, and a sliding block 321 is provided on the other of the main body 100 and the second force-applying member 320. The sliding block 321 is inserted into the sliding opening 101, and the sliding block 321 slides against the outside of the sliding opening 101. For example, the main body 100 may be provided with a sliding opening 101, and the sliding opening 101 extends in the moving direction of the second force-applying member 320. Sliding blocks 321 are respectively provided on opposite sides of the second force-applying member 320.

After the waste 20 is separated from the conveyor belt 200, it is moved out of the receiving groove 103 through the feeding port 104.

[0066] The receiving groove 103 is a long strip-shaped groove. The inner wall of the receiving groove 103 is spaced from the edge of the conveyor belt 200 by a gap, such as 0.5 mm to 1 mm, to avoid the friction between the inner wall and the conveyor belt 200 from increasing the moving resistance of the conveyor belt 200, and to prevent the waste 20 from getting stuck between the inner wall of the receiving groove 103 and the conveyor belt 200, and to prevent the waste 20 from falling below the conveyor belt 200. The receiving groove 103 serves to prevent the waste 20 from falling off from both side edges of the conveyor belt 200. The feeding port 104 is an opening formed at one end of the receiving groove 103 in the moving direction of the waste 20, that is, at one end of the moving direction of the receiving area, and is the opening at the end of the conveyor belt 200. When the waste 20 moves to the end of the conveyor belt 200, it disengages from the conveyor belt 200 and then is thrown out through the feeding port 104.

[0068] For example, the top end of the stripping plate 111 is used to act on the waste 20, and the top edge of the stripping plate 111 constitutes the bottom edge of the feeding port 104. When the conveyor belt 200 drives the waste 20 to move to the feeding port 104, the waste 20 will disengage from the conveyor belt 200 under the action of the bottom edge of the feeding port 104 and then fall.

[0069] In an optional embodiment, the main body 100 includes a lower shell 110 and an upper shell 120. The lower shell 110 and the upper shell 120 are detachably connected.

Then, the lower shell 110 and the upper shell 120 are connected by snapping the elastic buckle into the card slot.

[0071] In an optional embodiment, the waste moving mechanism further includes: a pressing component 500. The pressing component 500 is on the moving path corresponding to the receiving area. The pressing component 500 presses the conveyor belt 200 to make the conveyor belt 200 protrude outward.

[0072] Such as Figure 8As shown, the top end of the constant-pressure component 500 is at least higher than the top end of one of the roller components. The pressing component 500 can push up the conveyor belt 200 wound between the two roller components, so that the surface shape of the receiving area changes when it moves to the pressing component 500, and then the connection of the waste material 20 can be loosened in advance, which helps the waste material 20 to smoothly separate from the receiving area when it moves to the throwing position in the receiving area.

[0073] In an alternative embodiment, the pressing component 500 includes a connecting head 510 and a roller 520. The connecting head 510 is connected to the main body 100, the roller 520 is connected to the connecting head 510, and the roller 520 rolls and abuts against the conveyor belt 200.

[0074] The roller 520 can be a bearing, and the connecting head 510 can be a plug. As Figure 7 shown, a pressing seat 113 for connecting the pressing component 500 is provided on the main body 100. The connecting head 510 can be interference-fitted on the inner ring of the roller 520 and the pressing seat 113 respectively.

[0075] In an alternative embodiment, the waste material moving mechanism further includes: a scraping plate 600, which is connected to the main body 100 and is used for scraping the waste material 20 on the print head.

[0076] The scraping plate 600 is located behind the conveyor belt 200 in the direction of driving the waste material 20 to move, that is, on the path of the conveyor belt 200 moving towards the printing area after the print head 30 sprays out the waste material 20. The scraping plate 600 is used to scrape off the residual waste material 20 on the print head 30 to avoid affecting printing.

[0077] In an alternative embodiment, the scraping plate 600 includes a mounting frame 610 and a plate body 620. The mounting frame 610 is connected to the main body 100, and the plate body 620 is detachably connected to the mounting frame 610. The plate body 620 is used for scraping the waste material 20 on the print head 30.

The waste moving mechanism 10 is connected to the X-axis mechanism 40. For example, the main body 100 and the X-axis mechanism 40 are connected by bolts, and when the receiving area is in the receiving position, the print head 30 can move to the receiving area of the conveyor belt 200. The position of the receiving area includes a receiving position and a throwing position. When the print head 30 needs to eject waste 20, the print head 30 moves towards the waste moving mechanism 10, and the conveyor belt 200 pushes at least a part of the structure of the acting component 300 to move. For example, it can be to push the second force applying member 320 to move, so as to drive the receiving area to move towards the receiving position through the transmission component 330. At this time, the first force applying member 310 stores energy. When the receiving area is in the receiving position, the print head 30 faces the receiving area, as Figure 9 shown, and then ejects the waste 20. Then, the print head 30 moves away from the waste moving mechanism 10 and returns to the printing area. The print head 30 will pass by the scraping plate 600, and then scrape off the residual waste 20 at the bottom. The second force applying member 320 will move following the print head 30 under the action of the first force applying member 310, and the first force applying member 310 releases energy. The second force applying member 320 drives the receiving area to move towards the throwing position through the transmission component 330. The waste 20 will gradually separate from the receiving area under the combined action of the bending of the receiving area and the edge of the discharging plate 111 or the feeding port 104 until the receiving area reaches the throwing position, as Figure 10 shown, the waste 20 will be thrown out from the feeding port 104, and the print head 30 will continue to move and separate from the second force applying member 320.
