The printing assembly is described below in conjunction with specific embodiments to further understand the inventive concepts of the printing assembly. Referring to fig. 1, a printing assembly 10 includes: the blanking guide rails 100, the printing guide rails 200, the blanking mechanisms 300 and the printing mechanisms 400 are symmetrically arranged; each printing guide rail 200 and each blanking mechanism 300 are respectively arranged between two symmetrically arranged blanking guide rails 100; at least one of the printing guide rails 200 is slidably provided with one of the printing mechanisms 400.

Specifically, the blanking guide rail 100 and the printing guide rail 200 are both motion modules, and the specific structure thereof can be referred to as a transplanting motion module of a printing head and a sanding device for a 3D printer in the prior art, which is not described in detail in this embodiment. The specific number of the printing guide rails 200 and the blanking mechanisms 300 is set and installed according to actual printing requirements. In one embodiment, two symmetrically disposed blanking rails 100 are spaced apart on a support frame of the printing apparatus. In one embodiment, each printing guide rail 200 and each blanking mechanism 300 are connected to each other and disposed between two symmetrically disposed blanking guide rails 100. In one embodiment, each printing guide rail 200 and each blanking mechanism 300 are disposed between two symmetrically disposed blanking guide rails 100 at an interval. That is, each of the printing guide rails 200 and each of the blanking mechanisms 300 may be disposed in a mutually connected manner or disposed at intervals, and the installation manner is not particularly limited in this embodiment since the printing guide rails and the blanking mechanisms can synchronously reciprocate along with the movement of the blanking guide rails. In this way, by starting the symmetrically arranged blanking guide rails 100, the blanking mechanism 300 mounted on the blanking guide rails 100 and the printing guide rail 200 can be driven to move synchronously. After completing the printing operation in one direction, the blanking mechanism 300 and the printing guide rail 200 can move in the opposite direction synchronously by further controlling the blanking guide rail 100 to move in the opposite direction. That is, the movement direction of the blanking guide 100 is controlled to move in the forward and reverse directions within a certain stroke range, so that the circular reciprocating movement of the blanking mechanism 300 and the printing guide 200 can be realized. In the process, a plurality of blanking mechanisms and printing guide rails can be installed according to actual printing requirements, so that printing and blanking can be carried out synchronously, the whole printing process is continuously carried out, and the printing efficiency can be effectively improved. It should be noted that, when the number of the printing rails 200 is greater than or equal to 2, at least one of the printing rails 200 is ensured to be slidably provided with the printing mechanism 400, so that the printing mechanism 400 can move along the printing rails 200 to realize printing work in a direction perpendicular to the shakeout direction.

In this way, the cross beam 500 can facilitate more stable installation of the printing guide rail 200, and can effectively avoid the printing guide rail 200 and the blanking guide rail 100 from being affected when moving relative to each other. It should be noted that the printing guide rail 200 may be directly disposed between the two blanking guide rails 100, that is, it is not necessary to provide a beam support, but the provision of the beam can further ensure that the printing guide rail and the blanking guide rail are influenced by each other in motion.

That is, when the blanking mechanism 300 moves in the EF direction for blanking during normal operation, the left printing mechanism 400 moves together with the blanking mechanism 300 for printing; when the blanking mechanism 300 returns to blank in the GH direction, the right printing mechanism 400 moves together with the blanking mechanism 300 and performs printing. That is, the blanking mechanism 300 performs printing while performing the blanking operation in progress, and then performs printing operation simultaneously in the same manner as in the return stroke. Therefore, continuous printing operation can be realized, printing is not required to be carried out after blanking is finished, and the printing efficiency is relatively high.

In a preferred embodiment, the sliding block 410 is rotatably connected to the connecting block 620. Specifically, the sliding block 410 is mounted on the printing rail 200, and drives the printing head to reciprocate along the printing rail along with the printing rail 200, and when the printing head needs to be converted to another printing rail through the arched gantry mechanism 600 to move, the sliding block 410 is first detached from the printing rail, and the mounting angles of the sliding block 410 and the connecting block 620 are rotated, so that the printing head slides to the printing rail on the other side along the arched sliding rail 610.

Specifically, two blanking rails 210 are provided at the top ends of the support posts 110 of the support frame 100 in the Y-axis direction. Wherein, the printing mechanism 240 stores therein a spray material for printing to form the product profile. The blanking mechanism 230 has a base material stored therein for laying a product layer, for example, the base material is sand. In one embodiment, the support frame 100 has an inlet and an outlet on two symmetrical sides. Specifically, the entrance and exit are formed by two pillars arranged at an interval, wherein the width of the work box mechanism 300 is required to be smaller than the width of the entrance and exit, so that the work box mechanism 300 can slide into the inside of the support frame from one side of the support frame 100, so that the printing mechanism and the blanking mechanism print products on the work box, and slide out to the other side of the support frame after printing, or enter from the same side and slide out, and the moving path of the specific work box mechanism can be determined according to the actual process arrangement, which is not limited in this embodiment. The work box of work box mechanism 300 is for bearing the mechanism of printing the product, and the jacking piece is the mechanism of drive work box bottom plate, when printing mechanism and blanking mechanism cooperation print the during operation, the product shaping on the work box reduces work box bottom plate height gradually through jacking mechanism to can pile up the printing product gradually on the bottom plate of work box.

In one embodiment, the work box 310 is integrally disposed on top of the jack 320. Thus, by integrating the lift 320 with the work box 310 as a unitary structure, a quick integral transfer of the work box mechanism may be facilitated. Compare like this in the mode of only shifting the work box among the prior art, can effectively practice thrift and print latency, promptly after the work box that finishes printing shifts out with the jacking piece is whole, empty work box and jacking piece can take one's place next, and the location requirement reduces, can guarantee that work box bottom plate level is stable and not influenced by jacking piece and work box bottom plate status to when can realizing quick continuous printing, guarantee more efficient printing accuracy.

In one embodiment, referring to fig. 7, the work box mechanism 300 further includes a mounting platform 330, and the lifting member 320 is disposed on the mounting platform 330. By providing the mounting platform 330, reliable support of the jack 320 is facilitated. In one embodiment, the work box 310 includes a housing 311 and a bottom plate 312 movably disposed in the housing, and the bottom plate 312 is fixedly connected to the lifting member 320. By arranging the shell 311, the printed products on the bottom plate 312 can be conveniently prevented from overflowing, and the cleanness and sanitation of the production space are guaranteed. And be favorable to fixing a position between bottom plate and the jacking piece through with bottom plate 312 and jacking piece 320 fixed connection and confirm, be favorable to guaranteeing that the bottom plate surface is level and smooth stable to can avoid needing many times to fix a position and the easy unstable problem in bottom plate surface that appears when can avoid because bottom plate and jacking piece activity butt joint, thereby can ensure the product and print the precision.

In one embodiment, referring to fig. 8 and 9, the lifting element 320 includes a transmission mechanism 321 and a moving mechanism 322 connected to each other, and a fixing plate 323 supporting and disposing the transmission mechanism and the moving mechanism. In one embodiment, the transmission 321 includes a pneumatic cylinder or a motor drive. In one embodiment, the motion mechanism 322 comprises a hydraulic jack or a lead screw jack. The moving mechanism 322 includes a lower jacking mechanism 3221 and an upper jacking mechanism 3222 connected to the transmission mechanism 321, the lower jacking mechanism 3221 is connected to the fixing plate 323, and the upper jacking mechanism 3222 is connected to the bottom plate 312 of the work box. When the bottom plate of the work box needs to be raised, the transmission mechanism 321 is started, the upper jacking mechanism 3222 and the lower jacking mechanism 3221 extend simultaneously, and when the bottom plate of the work box needs to be lowered, the upper jacking mechanism 3222 and the lower jacking mechanism 3221 contract simultaneously. Therefore, the lower jacking mechanism 3221 and the upper jacking mechanism 3222 are driven by the transmission mechanism 321 to extend and contract, and then the bottom plate of the working box is driven to ascend or descend.

Preferably, the jacking member 320 further comprises a plurality of balance lifting columns 324 slidably connected to each other and a plurality of sliding blocks 325 mounted on the transmission mechanism 321, and each sliding block 325 is connected to one balance lifting column 324. The balance column 324 close to the bottom plate of the work box is connected with the bottom plate of the work box, and the balance lifting column 324 close to the fixing plate 323 is connected with the fixing plate 323. For example, the balance lifting column 324 connected to the fixed plate and the balance column 324 connected to the bottom plate of the work box are directly slidably connected to each other. This structure is similarly understood to mean that the strings of pipe are nested within each other, and can be extended or retracted relative to each other. For example, a third balancing lifting column is disposed between the balancing lifting column 324 connected to the fixing plate and the balancing column 324 connected to the bottom plate of the work box. The number of the third balance lifting columns can be increased according to the movement stroke of the movement mechanism. Preferably, the sliding blocks are arranged on two symmetrical sides of the top of the transmission mechanism 321, and each sliding block is in fit connection with a corresponding balance lifting column. When the bottom plate of the work box needs to be lifted, the transmission mechanism 321 is started to drive the movement mechanism 322 to ascend, so that the height position of the transmission mechanism is lifted, the balance columns connected with the sliding blocks are lifted, other balance columns connected with the balance columns are lifted in a staggered mode, and the bottom plate of the whole work box is supported. In a similar way, when the bottom plate of the working box needs to descend, the transmission mechanism drives the balance lifting columns to be close to each other and retract, and therefore the bottom plate of the working box is lowered to the height position synchronously.

To more stably support the work box, in a preferred embodiment, with continued reference to fig. 7, the mounting platform 330 is provided with a bracket 340, and the bracket 340 is connected to the housing 311 of the work box. Specifically, the bracket 340 is mounted to the bottom edge of the housing. The specific connection mode may be a fixed connection mode or a detachable connection mode, and the specific structure is not limited in this embodiment. Thus, the work box is more stably supported by the bracket 340. To facilitate manual pushing and pulling of the work box mechanism, in a preferred embodiment, the bracket 340 is provided with a push-pull handle 341. Thus, the worker can push the whole work box mechanism to move only by pushing and pulling the handle 341.

In one embodiment of the 3D printing apparatus, a plurality of printing guide rails 220 and a plurality of blanking mechanisms 230 are respectively disposed between two blanking guide rails 210. The specific number of the printing guide rails 220 and the blanking mechanisms 230 is set according to the actual printing requirement. In one embodiment, the blanking guide 210 and the printing guide 220 are motion modules. For the structure of the motion module, reference may be made to the motion module structure of the printing head and the sand spreader of the sand mold 3D printer in the prior art, which is not described in detail herein. In one embodiment, each printing guide rail and each blanking mechanism are arranged between two symmetrically arranged blanking guide rails at intervals. That is, each printing guide rail and each blanking mechanism may be connected to each other or disposed at an interval, and the installation manner of each printing guide rail and each blanking mechanism is not particularly limited in this embodiment since the printing guide rails and the blanking mechanisms can synchronously reciprocate along with the movement of the blanking guide rails. Therefore, the blanking guide rails which are symmetrically arranged are started, so that the blanking mechanism arranged on the blanking guide rails can be driven to synchronously move with the printing guide rails. After the stroke printing work in one direction is finished, the blanking mechanism and the printing guide rail can synchronously move in the opposite direction correspondingly by controlling the blanking guide rail to move in the opposite direction. That is, the reciprocating motion of the blanking mechanism and the printing guide rail can be realized by controlling the motion direction of the blanking guide rail to move in the positive and negative directions within a certain travel range. In the process, a plurality of blanking mechanisms and printing guide rails can be installed according to actual printing requirements, so that printing and blanking can be carried out synchronously, the whole printing process is continuously carried out, and the printing efficiency can be effectively improved. It should be noted that, when the number of the printing guide rails is greater than or equal to 2, at least one of the printing guide rails 2 is ensured to be provided with the printing mechanism in a sliding manner, so that the printing mechanism can move along the printing guide rails to realize printing work in a direction perpendicular to the shakeout direction. That is, there is a portion of the printing guide rail that may not be provided with a mounting printing mechanism, which will be described in connection with the following embodiments.
