In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0046] The present embodiment provides a 3D printer, as shown in Figure 1 and Figure 2 The 3D printer includes a main body mechanism 10 and a shell mechanism 20, wherein the main body mechanism 10 includes a support platform 11 for mounting a printer main body (not shown in the figure), and the shell mechanism 20 is arranged outside the main body mechanism 10, so as to protect the main body mechanism 10 and avoid damage to the printer main body due to direct impact from the outside.

[0047] As shown in Figure 2As shown, the 3D printer further comprises a connecting mechanism, which has a first state and a second state between the main body mechanism 10 and the shell mechanism 20. In the first state, the shell mechanism 20 is fixedly connected with the main body mechanism 10 through the connecting mechanism; in the second state, the connecting mechanism is disassembled, and the shell mechanism 20 is separated from the main body mechanism 10. Therefore, during the transportation of the 3D printer, the shell mechanism 20 can be fixedly connected with the main body mechanism 10 as a whole, thereby facilitating the transportation; when the main body mechanism 10 needs to work, the connecting mechanism is disassembled to separate the main body mechanism 10 from the shell mechanism 20, thereby avoiding the vibration of the shell mechanism 20 caused by external force from being transmitted to the main body mechanism 10, and further ensuring better printing effect.

[0048] Optionally, during the transportation of the 3D printer, the main body mechanism 10 is supported on a support surface (such as a surface in the carriage of a transport vehicle for carrying the 3D printer), and the shell mechanism 20 can be supported on the support surface or in a suspended state. When the lower end of the shell mechanism 20 is in a suspended state, the vibration between the main body mechanism and the shell mechanism caused by the vibration out of synchronization can be avoided from being transmitted through the connecting mechanism.

[0049] As shown in Figure 1 and Figure 2 , the shell mechanism 20 comprises a bottom plate assembly 21 and a shell assembly 22, wherein the bottom plate assembly 21 is configured in a ring shape and surrounds the outer periphery of the support platform 11, and the shell assembly 22 is connected with the bottom plate assembly 21 and covers the outside of the main body mechanism 10. In this embodiment, the bottom plate assembly 21 is configured in a rectangular frame structure. The shell assembly 22 comprises a front panel 221, a rear panel, two side panels 222, and a top panel 223. The front panel 221 and the rear panel are oppositely arranged and respectively located at the front side and the rear side of the main body mechanism 10, and the lower ends of the front panel 221 and the rear panel are connected with the bottom plate assembly 21. The two side panels 222 are oppositely arranged and respectively located at the left side and the right side of the main body mechanism 10, and the lower ends of the side panels 222 are connected with the bottom plate assembly 21, and the front and rear ends are respectively connected with the front panel 221 and the rear panel. The top panel 223 is arranged at the top of the main body mechanism 10 and is connected with the front panel 221, the rear panel, and the two side panels 222, thereby achieving overall covering protection of the main body mechanism 10. In this embodiment, the front side plate 3121 comprises a main body plate 2211 and a movable plate 2212, the main body plate 2211 is provided with a window, the window is opposite to the main body of the printer, and the movable plate 2212 is movably connected with the main body plate 2211 to open and close the window, thereby facilitating the operator to operate the main body of the printer.

[0052] As shown in Figure 2 and Figure 3 As shown in

[0053] In the assembly of the 3D printer, the assembly of the components of the main body mechanism 10, the assembly of the partial shell component 22 and the first bottom plate 211, and the assembly of the partial shell component 22 and the second bottom plate 212 can be performed synchronously. When the main body mechanism 10 is assembled, it is pushed into the first bottom plate 211 from the gap of the first bottom plate 211, and then the second bottom plate 212 is connected with the first bottom plate 211. Through the above arrangement, the assembly efficiency of the 3D printer can be improved, and the main body mechanism 10 does not need to be lifted during the process of being placed into the shell mechanism 20, thereby improving the assembly convenience of the 3D printer. In the embodiment, the first bottom plate 211 is configured in a U shape, so that the main body mechanism 10 can be assembled from the gap of the first bottom plate 211. Alternatively, the first bottom plate 211 can be integrally formed or assembled by a plurality of strip-shaped components, which is not limited herein. Alternatively, one of the front side plate 3121, the rear side plate 3121, and the two side plates 222 is connected with the second bottom plate 212, and the other three are connected with the first bottom plate 211.

[0054] As shown in Figure 4 , the support platform 11 includes a support frame 111 and a bearing table 112, and the bearing table 112 is installed on the top of the support frame 111. The bearing table 112 is used to install the printer body. The support frame 111 can support the bearing table 112 and the printer body to an appropriate height, and the overall weight is relatively light. The bearing table 112 provides a flat support surface to more stably support the printer body. In the embodiment, the second roller assembly 13 is installed below the support frame 111.

[0055] As shown in Figure 2 and Figure 4 , the connection mechanism includes a first connection assembly 30 and a second connection assembly 40. The first connection assembly 30 connects the lower end of the support platform 11 and the shell mechanism 20, and the second connection assembly 40 connects the upper end of the support platform 11 and the shell mechanism 20. The first connection assembly 30 and the second connection assembly 40 are arranged in a vertical direction. In the embodiment, by arranging the first connection assembly 30 and the second connection assembly 40 in a vertical direction, the reliable connection between the shell mechanism 20 and the support platform 11 can be ensured, and the force acting on the shell mechanism 20 is more uniform, avoiding the inclination and falling of the shell mechanism 20 due to road bumps during transportation, and ensuring the safety of the 3D printer during transportation.

[0056] In this embodiment, the first connecting assembly 30 connects the lower end of the support frame 111 and the lower end of the housing mechanism 20, and the second connecting assembly 40 connects the bearing table 112 and the middle part of the housing mechanism 20. Specifically, the lower end of the support frame 111 has a crossbeam 1111, and the first connecting assembly 30 is connected at the crossbeam 1111. Optionally, two first connecting assemblies 30 are provided and symmetrically arranged, so as to improve the uniformity of the acting force between the bottom plate assembly 21 and the support platform 11. In other embodiments, the number of the first connecting assemblies 30 can be flexibly arranged. Optionally, four second connecting assemblies 40 are provided, and the four second connecting assemblies 40 are symmetrically distributed, so as to further improve the uniformity of the acting force between the housing assembly 22 and the support platform 11. In other embodiments, the number of the second connecting assemblies 40 can be flexibly arranged according to needs. In addition, it should be noted that when the first connecting assembly 30 and the second connecting assembly 40 are installed or disassembled, part of the housing assembly 22 can be disassembled, so as to improve the convenience of operation.

[0057] As shown in Figure 2 , Figures 5-7 , the first connecting assembly 30 comprises a first connecting piece 31, the first connecting piece 31 comprises a bottom 311 and a first extension 312, the first extension 312 is formed by extending from one end of the bottom 311, the first extension 312 is lapped on the support platform 11 and connected with the support platform 11, and the bottom 311 supports the bottom plate assembly 21 and is connected with the bottom plate assembly 21. Since the main body mechanism 10 is relatively heavy and the housing mechanism 20 is relatively light, by arranging the first extension 312 to lap on the support platform 11 and the bottom 311 to support the lower side of the bottom plate assembly 21, the housing mechanism 20 can be well supported, and the reliability of the connection between the housing mechanism 20 and the main body mechanism 10 is ensured. In this embodiment, the first extension 312 is lapped on the crossbeam 1111 at the lower end of the support frame 111.

[0058] As shown in Figure 6As shown, the first extension 312 includes a side plate 3121 and a top plate 3122, with the side plate 3121 connecting the bottom 311 and the top plate 3122. The top plate 3122 has a first connecting hole 31221 extending axially in a first direction, and a first fastener passes through the first connecting hole 31221 to connect the top plate 3122 and the support platform 11. Specifically, the support platform 11 (i.e., the upper surface of the crossbeam 1111) has a first mating hole corresponding to the first connecting hole 31221, and the first fastener passes through both the first connecting hole 31221 and the first mating hole to connect the top plate 3122 and the support platform 11. The side plate 3121 has a second connecting hole 31211 extending axially in a second direction, and a second fastener passes through the second connecting hole 31211 to connect the side plate 3121 and the support platform 11. Specifically, the support platform 11 (i.e., the side surface of the crossbeam 1111) is provided with a second mating hole corresponding to the second connecting hole 31211. The second direction is set at an angle to the first direction. The second fastener passes through the second connecting hole 31211 and the second mating hole to connect the side plate 3121 and the support platform 11. That is to say, in this embodiment, the first extension 312 is connected to the support platform 11 through two sets of fasteners with different axial directions, thereby improving the stability and reliability of the connection between the first connector 31 and the support platform 11.

[0059] In this embodiment, the first direction and the second direction are perpendicular to each other, with the first direction being vertical and the second direction being horizontal. In other embodiments, the angle between the first direction and the second direction can also be acute. For example... Figure 5 As shown, the top plate 3122 is horizontally positioned and overlaps the upper surface of the crossbeam 1111, while the side plate 3121 is vertically positioned and fits against the side surface of the crossbeam 1111. Optionally, the number of first connecting holes 31221 on the top plate 3122 can be one, two, three, or more. The number of second connecting holes 31211 on the side plate 3121 can also be one, two, three, or more.

[0060] like Figure 6 As shown, a third connecting hole 3111 is provided on the bottom 311 of the first connector 31, and a third mating hole 2111 corresponding to the third connecting hole 3111 is provided on the base plate assembly 21. Fasteners pass through the third connecting hole 3111 and the third mating hole 2111 to connect the bottom 311 and the base plate assembly 21. Optionally, the number of third connecting holes 3111 can be one, two, three or more, which is not limited here.

[0061] like Figure 6As shown, the first connecting hole 31221 is an elongated hole extending along the second direction, and the third connecting hole 3111 is also an elongated hole extending along the second direction. Therefore, when there is some deviation in the relative position of the main body mechanism 10 and the outer shell mechanism 20 in the second direction, or when there is a deviation in the machining of the first mating hole and the second mating hole on the main body mechanism 10, or when there is a deviation in the machining of the third mating hole 2111 on the base plate assembly 21, the setting of the elongated hole can compensate for the above deviation, thereby ensuring that the first connecting member 31 can smoothly connect the main body mechanism 10 and the outer shell mechanism 20.

[0062] like Figure 6 As shown, the second connecting hole 31211 is an elongated hole extending along a third direction, which is perpendicular to both the first and second directions, meaning the third direction is also a horizontal direction. Even when the machining position of the second mating hole deviates slightly along the third direction, the first connecting piece 31 can still be installed smoothly.

[0063] like Figure 5 and Figure 6 As shown, the first connecting member 31 also includes a reinforcing part 315, which connects the bottom 311 and the side plate 3121. Since the side plate 3121 and the bottom 311 are subjected to greater forces, providing a reinforcing part 315 at their intersection ensures the structural strength of the entire first connecting member 31, thereby improving the reliability of the connection between the main body mechanism 10 and the outer shell mechanism 20. In this embodiment, the reinforcing part 315 is constructed as a sheet metal part and is perpendicular to both the side plate 3121 and the bottom 311. Optionally, the reinforcing part 315 can be connected to the bottom 311 and the side plate 3121 by welding. The number of reinforcing parts 315 can be one, two, three, or more.

[0064] Optionally, such as Figure 7 As shown, the overlap width between the top plate 3122 and the support platform 11 is greater than the gap width between the bottom plate assembly 21 and the reinforcing part 315. This arrangement, on the one hand, brings the distance between the bottom plate assembly 21 and the support platform 11 closer, which helps improve the overall structural compactness of the 3D printer; on the other hand, when the first fastener connecting the top plate 3122 and the crossbeam 1111, and the fastener connecting the bottom 311 and the bottom plate assembly 21 are removed, based on the aforementioned width relationship, the first connecting piece 31 will not fall arbitrarily to the bottom of the support platform 11 and become difficult to remove. For details on how to remove the first connecting piece 31, please refer to the 3D printer debugging method below.

[0065] like Figure 7 As shown, the reinforcing part 315 has an inclined edge 3151 on the side facing the base plate assembly 21, and the inclined edge 3151 is inclined towards the support platform 11 in an upward direction. This arrangement facilitates the insertion of the entire first connector 31 between the base plate assembly 21 and the support platform 11.

[0066] In the embodiment, as shown in Figure 6 The number of the first connecting holes 31221 and the third connecting holes 3111 is three, and the number of the second connecting holes 31211 is two. The three first connecting holes 31221, the three third connecting holes 3111 and the two second connecting holes 31211 are arranged uniformly along the third direction respectively, and the second connecting holes 31211 are arranged spaced apart from the reinforcing part 315.

[0067] As shown in Figure 5 and Figure 6 The first connecting part 31 further comprises a second extending part 313 formed extending upward from the other end of the bottom part 311. The second extending part 313 can strengthen the overall structure of the first connecting part 31. Alternatively, the bottom part 311, the first extending part 312 and the second extending part 313 can be integrally formed by bending sheet metal. The integrally formed structure can provide the first connecting part 31 with higher structural strength, thereby avoiding damage during transportation of the 3D printer.

[0068] As shown in Figure 6 and in combination with Figure 5 The second extending part 313 is provided with a first long hole 3131 extending in the horizontal direction, and the bottom plate assembly 21 is provided with a positioning hole 2112 corresponding to the first long hole 3131. The first connecting assembly 30 further comprises a positioning part, which is inserted into the first long hole 3131 and the positioning hole 2112, thereby connecting with the bottom plate assembly 21. When installing the first connecting part 31, the positioning part can be inserted into the first long hole 3131 and the positioning hole 2112 to position the installation position of the first connecting part 31, thereby improving the installation efficiency of the first connecting part 31. In the embodiment, the first long hole 3131 extends along the third direction, so that the position of the first connecting part 31 in the third direction can be adjusted when the positioning part is installed, thereby ensuring that the first connecting holes 31221 correspond to the first matching holes in the third direction, and the third connecting holes 3111 correspond to the third matching holes 2111 in the third direction, thereby ensuring smooth installation of the first connecting part 31.

[0069] As shown in Figure 7 Along the axial direction of the first long hole 3131 (i.e. along the second direction), the second extending part 313 and the housing mechanism 20 have a gap 314. Such arrangement can ensure that the bottom plate assembly 21 can be placed on the bottom part 311 smoothly, avoid interference between the bottom plate assembly 21 and the second extending part 313 during placement of the bottom plate assembly 21 on the bottom part 311, and improve the convenience of assembly.

[0070] As shown in Figure 2 and Figure 8As shown, the second connecting assembly 40 comprises a second connecting member 41 and a third connecting member 42, the second connecting member 41 is connected with the housing mechanism 20, the third connecting member 42 is connected with the support platform 11, the second connecting member 41 and the third connecting member 42 are connected by the third fastener, and the connecting position of the second connecting member 41 and the third connecting member 42 is adjustable. The processing of the structure for connecting the second connecting assembly 40 on the main body mechanism 10 and the housing mechanism 20 can have deviation, and after the first connecting member 31 is installed, the position between the main body mechanism 10 and the housing mechanism 20 can have certain deviation, and in the embodiment, the second connecting assembly 40 is provided as two components, and the connecting position between the two components is adjustable, that is, the above-mentioned error can be compensated by adjusting the connecting position of the two components, so as to ensure that the entire second connecting assembly 40 is installed smoothly.

[0071] In the embodiment, as shown in Figure 2 and Figure 8 , the second connecting member 41 is configured as an L-shaped structure, the second connecting member 41 comprises a first plate 411 and a second plate 412, the third connecting member 42 is also configured as an L-shaped structure, the third connecting member 42 comprises a third plate 421 and a fourth plate 422, wherein the first plate 411 is connected with the housing assembly 22, the third plate 421 is connected with the support platform 112, and the second plate 412 and the fourth plate 422 are attached and connected.

[0072] As shown in Figure 8 , one of the second connecting member 41 and the third connecting member 42 is provided with a second long hole 4221 extending in the horizontal direction, and the other of the second connecting member 41 and the third connecting member 42 is provided with a through hole 4121, and the third fastener passes through the second long hole 4221 and the through hole 4121 to connect the second connecting member 41 and the third connecting member 42. When the relative distance between the housing mechanism 20 and the main body mechanism 10 has deviation, the second long hole 4221 can compensate for the deviation to ensure that the second connecting assembly 40 can be connected between the housing mechanism 20 and the main body mechanism 10. In the embodiment, the second long hole 4221 is provided on the fourth plate 422 of the third connecting member 42 and extends in the second direction, and the through hole 4121 is provided on the second plate 412 of the second connecting member 41. Alternatively, the number of through holes 4121 can be one, two or more. In other embodiments, the second long hole 4221 can be provided on the second plate 412 of the second connecting member 41, and the through hole 4121 can be provided on the fourth plate 422 of the third connecting member 42.

[0073] The second connecting assembly 40 further comprises a fourth fastener and a fifth fastener, as shown in Figure 8As shown, the second connecting member 41 is provided with a first mounting hole 4111, and the third connecting member 42 is provided with a second mounting hole 4211. The fourth fastener is threaded through the first mounting hole 4111 and connected with the housing mechanism 20, and the fifth fastener is threaded through the second mounting hole 4211 and connected with the support platform 11. At least one of the first mounting hole 4111 and the second mounting hole 4211 is an elongated hole extending in the vertical direction. When there is a deviation in the relative position between the bearing table 112 and the housing assembly 22 in the vertical direction, or the hole position on the housing assembly 22 for cooperating with the first mounting hole 4111 is deviated, or the hole position on the bearing table 112 for cooperating with the second mounting hole 4211 is deviated, one of the first mounting hole 4111 and the second mounting hole 4211 is provided as an elongated hole extending in the vertical direction to compensate for the deviation, so as to ensure that the second connecting assembly 40 can be smoothly connected with the housing assembly 22 and the bearing table 112. In the embodiment, the first mounting hole 4111 is a circular hole, and the second mounting hole 4211 is an elongated hole extending in the vertical direction. In other embodiments, the first mounting hole 4111 can be an elongated hole extending in the vertical direction, the second mounting hole 4211 can be a circular hole, or both the first mounting hole 4111 and the second mounting hole 4211 can be elongated holes extending in the vertical direction.

[0074] As shown, Figure 2 The housing mechanism 20 further includes a first adjusting assembly 23 connected with the bottom plate assembly 21, for adjusting the height of the bottom plate assembly 21 (i.e. the height relative to the support surface on which the main body mechanism 10 is supported). By adjusting the height of the bottom plate assembly 21 through the first adjusting assembly 23, not only can the housing mechanism 20 better cooperate with the disassembly and assembly of the connecting mechanism, improving the convenience of debugging before and after the 3D printer is transported, but also the lower end of the housing mechanism 20 can be suspended through the first adjusting assembly 23 during transportation, avoiding damage caused by the vibration of the main body mechanism 10 and the housing mechanism 20 through the connecting mechanism during the road bumps.

[0075] In the embodiment, the housing mechanism 20 includes four first adjusting assemblies 23, which can not only adjust the height of the bottom plate assembly 21, but also level the bottom plate assembly 21, thereby ensuring the stability of the housing mechanism 20. In other embodiments, the housing mechanism 20 can be provided with three or more first adjusting assemblies 23. Specifically, as shown, Figure 2As shown, the first adjusting assembly 23 comprises a base 232 and a screw rod 231, wherein the screw rod 231 is screwed with the base plate assembly 21, the base 232 is connected at the lower end of the screw rod 231 and used to contact with the supporting surface, and rotating the screw rod 231 can adjust the distance between the base 232 and the base plate assembly 21. When the base 232 is supported on the supporting surface, rotating the screw rod 231 can adjust the height of the base plate assembly 21, and when the base plate assembly 21 is connected with the main body mechanism 10, rotating the screw rod 231 can make the base 232 suspended.

[0076] As shown in FIG. 1, the main body mechanism 10 further comprises a second adjusting assembly 12, which is installed below the supporting platform 11. The second adjusting assembly 12 can adjust the height of the supporting platform 11. In the embodiment, the main body mechanism 10 comprises four second adjusting assemblies 12, and by adjusting the four second adjusting assemblies 12 respectively, the supporting platform 11 can be leveled, so as to ensure that the printer main body on the supporting platform 11 can be supported in an accurate posture. The specific structure of the second adjusting assembly 12 is the same as that of the first adjusting assembly 23, and will not be repeated here. Figure 2 The transportation debugging method of the 3D printer in the embodiment comprises debugging before transportation and debugging after transportation, wherein:

[0077] The debugging before transportation comprises the following steps:

[0078] S110, adjusting the base plate assembly 21 to a first height by the first adjusting assembly 23;

[0079] S120, placing at least part of the connecting mechanism between the main body mechanism 10 and the shell mechanism 20;

[0080] S130, adjusting the base plate assembly 21 to a second height by the first adjusting assembly 23, so that the base plate assembly 21 contacts with the connecting mechanism;

[0081] S140, fixedly connecting the connecting mechanism with the shell mechanism 20 and the base plate assembly 21 respectively.

[0082]

[0083] ​In the debugging process before the transportation of the embodiment, the first adjusting assembly 23 is used to adjust the bottom plate assembly 21 to the first height. At the first height, the first extension 312 of the first connecting piece 31 is overlapped on the cross beam 1111 of the support frame 111, and the lower surface of the bottom plate assembly 21 is not in contact with the bottom 311 of the first connecting piece 31, so as to facilitate the fine adjustment of the position of the first connecting piece 31 in the horizontal direction (i.e. the third direction). When the approximate position of the first connecting piece 31 in the third direction is adjusted, the bottom plate assembly 21 is adjusted to the second height. At the second height, the lower surface of the bottom plate assembly 21 is in contact with the bottom 311 of the first connecting piece 31. At this time, the first connecting piece 31 and the bottom plate assembly 21, the first connecting piece 31 and the support platform 11 are connected by the fasteners respectively, and the second connecting assembly 40 is connected with the shell assembly 22 and the support platform 11 by the fasteners respectively. At this time, the shell mechanism 20 and the main body mechanism 10 are in the first state of connection.

[0084] It can be understood that, in the process of transporting the 3D printer, the first adjusting assembly 23 can be selected to be suspended or in contact with the support surface of the support main body mechanism 10 by adjusting the first adjusting assembly 23.

[0085] Preferably, in the debugging process before the transportation, before the first connecting piece 31 is fixedly connected with the shell mechanism 20 and the bottom plate assembly 21 by the fasteners, step S150 is performed, i.e. the position of the connecting mechanism relative to the main body mechanism 10 and the shell mechanism 20 is adjusted by the positioning piece. This step can assist in adjusting the position of the first connecting piece 31 in the third direction, thereby improving the installation efficiency of the first connecting piece 31, and further improving the efficiency of the debugging process before the transportation.

[0086] The debugging after the transportation includes the following steps:

[0087] S210, adjusting the first adjusting assembly 23 to be in contact with the support surface;

[0088] S220, releasing the fixed connection of the connecting mechanism with the shell mechanism 20 and the bottom plate assembly 21 respectively;

[0089] S230, adjusting the bottom plate assembly 21 to the third height by the first adjusting assembly 23, so as to separate the bottom plate assembly 21 from the connecting mechanism;

[0090] S240, removing the connecting mechanism from between the main body mechanism 10 and the shell mechanism 20.

[0091] In the debugging process after the transportation of the embodiment, the first adjusting assembly 23 is first adjusted to be in contact with the supporting surface. When the connecting mechanism is respectively fixedly connected with the shell mechanism 20 and the bottom plate assembly 21, the shell mechanism 20 will not fall off, thereby avoiding damage to the shell mechanism 20. After the connecting mechanism is respectively connected with the shell mechanism 20 and the bottom plate assembly 21, the bottom plate assembly 21 is first adjusted to the third height, so that the bottom plate assembly 21 is separated from the first connecting piece 31. At this time, the bottom plate assembly 21 no longer exerts force on the first connecting piece 31, so that the first connecting piece 31 is smoothly taken out from between the main body mechanism 10 and the bottom plate assembly 21. At this time, the shell mechanism 20 and the main body mechanism 10 are in the second state of separation. It should be noted that the first height and the third height can be the same height or different heights, which are not specifically limited here.
