[0033] Please refer to Figure 1 andFigure 2 This application provides a printer, including a printing device 200 and a feeding mechanism 100. The feeding mechanism 100 is used to transport the medium after printing by the printing device 200 to the next process, such as, but not limited to, the cutting process, i.e., to the cutting device 300. The following description uses the cutting device 300 as an example.

[0034] Please refer to Figure 1 and Figure 2 The printing device 200 includes a printing platform 210, a guide beam 220, a printing carriage 230, and a second drive mechanism 240. The printing platform 210 carries the media, the guide beam 220 is positioned above the printing platform 210, the printing carriage 230 is mounted on the guide beam 220, and the second drive mechanism 240 drives the guide beam 220 to slide along a first direction X, moving the printing carriage 230 from the printing start end 211 to the printing end end 212 of the printing platform 210, thereby enabling the printing carriage 230 to print the entire media.

[0035] During actual printing, the operator places the media onto the printing platform 210, arranging it neatly front-to-back and left-to-right. The second drive mechanism 240 moves the guide beam 220 to the printing start end 211. The fan inside the printing platform 210 starts working, sucking in the media, and the printing carriage 230 begins printing. During printing, the second drive mechanism 240 moves the guide beam 220 and the printing carriage 230 towards the printing end end 212 to achieve full printing of the media. After printing, the unloading mechanism 100 conveys the media to the cutting device 300, which cuts the media. After cutting, the operator removes the media, achieving continuous printing and cutting processes and improving media production efficiency.

[0036] Please see Figures 1 to 5 The feeding mechanism 100 provided in this application embodiment will now be described. This feeding mechanism 100 is used to transport the medium printed by the printing device 200 to the next process. The printing device 200 can be a flatbed printer, inkjet printer, or other types of printing device 200.

[0037] The feeding mechanism 100 comprises an extension assembly 110, a mounting rack 120, a first driving mechanism 130 and a plurality of adsorption assemblies 140; the extension assembly 110 extends along a first direction X, the mounting rack 120 is slidingly arranged on the extension assembly 110 along the first direction X; each adsorption assembly 140 is sequentially and spacedly arranged on the mounting rack 120 along a second direction Y and is used for adsorbing media respectively; the first driving mechanism 130 is used for driving the mounting rack 120 to slide along the first direction X, and the first direction X is arranged as the distribution direction of the printing device 200 and the next process, wherein the first direction X is the direction of the connection line between the printing starting end 211 and the printing ending end 212, and the second direction Y is perpendicular to the first direction X.

[0038] The feeding mechanism 100 in the embodiment of the application can adsorb and fix the media after printing by the printing device 200 through sequentially and spacedly arranging the adsorption assemblies 140 on the mounting rack 120 along the second direction Y and adsorbing the media respectively; the mounting rack 120 is driven to slide along the first direction X by the first driving mechanism 130, so that the media can be moved along the first direction X, and the media can be conveyed from the printing device 200 to the next process, thereby realizing automatic feeding of the media and saving labor.

[0039] In some embodiments, referring to Figure 1 and Figure 2 , the extension assembly 110 is arranged to slide along the first direction X on the printing device 200. Specifically, the extension assembly 110 can be slid along the first direction X to the upper side of the printing platform 210, so as to move the mounting rack 120 and the adsorption assemblies 140 to the upper side of the media and adsorb the media by the adsorption assemblies 140; then the extension assembly 110 is moved to the cutting device 300, until the extension assembly 110 extends from the printing ending end 212 of the printing platform 210 to the cutting device 300; then the mounting rack 120 and the adsorption assemblies 140 are driven to slide to the cutting device 300 by the first driving mechanism 130, so that the adsorption assemblies 140 can convey the media to the cutting device 300. In the embodiment, the extension assembly 110 is arranged to slide along the first direction X, so as to increase the sliding stroke of the adsorption assemblies 140 along the first direction X, thereby facilitating the conveying of the media between the printing platform 210 and the cutting device 300. It can be understood that in other embodiments of the application, the extension assembly 110 can be fixed on the upper side of the printing platform 210, and the extension assembly 110 can extend from the printing starting end 211 of the printing platform 210 to the upper side of the cutting device 300, thereby reducing the conveying stroke of the media.

[0040] In some specific embodiments, referring to Figure 2 and Figure 3The extension assembly 110 is connected to the guide rail beam 220 of the printing device 200, and when the second driving mechanism 240 drives the guide rail beam 220 to move along the first direction X, the extension assembly 110, the mounting frame 120 and the suction assembly 140 can be simultaneously moved along the first direction X, so as to move the suction assembly 140 to the upper side of the medium to adsorb the medium, and the extension assembly 110 can also be slid along the first direction X to the printing end 212 of the printing platform 210, so that the extension assembly 110 can extend outward from the printing end 212 of the printing platform 210, so as to facilitate the medium to be conveyed to the cutting device 300. In the embodiment, the extension assembly 110 is designed to be mounted on the guide rail beam 220, so that the driving structure of the extension assembly 110 is simple. It can be understood that in other embodiments of the present application, a third driving mechanism can be additionally arranged on the printing device 200 to drive the extension assembly 110 to move along the first direction X, which is not limited herein.

[0041] In some embodiments, referring to Figure 1 and Figure 5 , the extension assembly 110 includes two extension arms 111 which are oppositely arranged along the second direction Y, and the mounting frame 120 is slidably arranged at the opposite ends of the two extension arms 111 along the second direction Y. By arranging the two extension arms 111, each suction assembly 140 can be distributed between the two extension arms 111, and the medium can be adsorbed between the two extension arms 111, so as to avoid the extension arms 111 from hindering the suction assembly 140 from adsorbing the medium. It can be understood that in other embodiments of the present application, the extension assembly 110 can also include one, three or more than three extension arms 111, which is not limited herein.

[0042] In the present application, referring to Figures 3 to 5 , when the extension assembly 110 includes two extension arms 111, the first ends of the two extension arms 111 can be locked and mounted on the opposite ends of the guide rail beam 220 along the second direction Y by the two connecting pieces 150. When the guide rail beam 220 is slid to the printing end 212 of the printing platform 210, the second ends of the two extension arms 111 extend to the outside of the printing platform 210, so as to facilitate the mounting frame 120 and the suction assembly 140 to be slid to the outside of the printing platform 210, thereby facilitating the medium to be conveyed to the cutting device 300.

[0043] Optionally, the two extension arms 111 are parallel to each other, and the parallel degree of the two extension arms 111 is within the range of plus or minus 1 mm, so as to ensure the parallel precision of the two extension arms 111, thereby ensuring the stability of the medium adsorption and conveying.

[0044] In some embodiments, referring to Figure 5 and Figure 6The first driving mechanism 130 comprises a first driving member 131, a synchronous structure 132 and two transmission structures 133. The first driving member 131 is connected with one of the transmission structures 133. The synchronous structure 132 is used to realize synchronous movement of the two transmission structures 133. The two transmission structures 133 are respectively connected with opposite ends of the mounting rack 120. In this embodiment, the synchronous movement of the two transmission structures 133 is realized through the synchronous structure 132. Thus, only one first driving member 131 needs to be designed. The opposite ends of the mounting rack 120 can be respectively driven to move through the two transmission structures 133. Meanwhile, the synchronous movement of the opposite ends of the mounting rack 120 can be ensured. The movement stability and movement precision of the mounting rack 120 are ensured. It can be understood that in other embodiments of the present application, the synchronous structure 132 can not be arranged. Two first driving members 131 are arranged corresponding to the two transmission structures 133. The two transmission structures 133 are respectively driven through the two first driving members 131. Thus, the opposite ends of the mounting rack 120 are driven to move. At this time, the two first driving members 131 can be controlled to be synchronously driven through a controller. Thus, the synchronous movement of the opposite ends of the mounting rack 120 can be ensured.

[0045] In some embodiments, referring to Figure 5 and Figure 7 The transmission structure 133 is mounted on the extension arm 111. The transmission structure 133 comprises a first synchronous belt structure. The extension arm 111 is provided with a guide structure 112 used to guide the sliding movement of the mounting rack 120.

[0046] Specifically, referring to Figure 7 The first synchronous belt structure comprises two first synchronous pulleys 1331 and two first synchronous belts 1332. The two first synchronous pulleys 1331 are arranged along the first direction X and are spaced apart from each other on the extension arm 111. The first driving member 131 outputs rotary movement. One of the first synchronous pulleys 1331 is connected with the output end of the first driving member 131. The first synchronous belts 1332 are respectively engaged with the two first synchronous pulleys 1331. The opposite ends of the mounting rack 120 are respectively mounted on the two first synchronous belts 1332. The first driving member 131 outputs rotary movement to drive one of the first synchronous pulleys 1331 to rotate. Thus, the first synchronous belts 1332 are driven to move. Thus, the mounting rack 120 is driven to move. In this embodiment, the movement transmission between the first driving member 131 and the mounting rack 120 is realized through the first synchronous belt structure. The transmission stability is good. The occupied space is small. It can be understood that in other embodiments of the present application, the transmission structure 133 can also be a ball screw structure or a gear and rack structure. This is not limited here.

[0047] Specifically, referring to Figure 6 and Figure 7The guide structure 112 includes a guide rod 1121 mounted on the extension arm 111 and a sliding block 1122 connected to the mounting rack 120. The guide rod 1121 is arranged between the two first synchronous pulleys 1331 and located in a track-shaped cavity enclosed by the first synchronous belt 1332. The sliding block 1122 is slidingly arranged on the guide rod 1121, and the sliding block 1122 is fixedly connected with the first synchronous belt 1332. When the first synchronous belt 1332 moves, the mounting rack 120 can slide through the sliding block 1122, and the sliding block 1122 slides along the guide rod 1121 to ensure the sliding stability and precision of the mounting rack 120.

[0048] Optionally, the first driving member 131 includes a rotary motor or a rotary cylinder for outputting rotary motion.

[0049] In some embodiments, referring to Figure 6 The synchronous structure 132 includes a second synchronous belt structure. Specifically, the second synchronous belt structure includes two second synchronous pulleys 1321 and a second synchronous belt 1322. The two second synchronous pulleys 1321 are respectively mounted on the two extension arms 111, and are coaxially arranged with the two first synchronous pulleys 1331 arranged opposite to each other along the second direction Y. The second synchronous belt 1322 is engaged with the two second synchronous pulleys 1321 for synchronous rotation of the two first synchronous pulleys 1331, synchronous movement of the two first synchronous belts 1332, and synchronous movement of the opposite ends of the mounting rack 120. It can be understood that in other embodiments of the present application, synchronous movement of the two transmission structures 133 can also be achieved by chain wheel structure, gear structure, two sets of gear and rack structure, etc., which are not limited herein.

[0050] In some embodiments, referring to Figure 7 At least one end of the extension arm 111 is provided with a buffer member 113 for buffering the mounting rack 120. The buffer member 113 is mainly used for buffering the sliding of the mounting rack 120, so as to avoid vibration of the mounting rack 120 caused by direct collision of the mounting rack 120 with the end of the extension arm 111.

[0051] Optionally, referring to Figure 7 The second end of the extension arm 111 away from the printing device 200 is provided with a buffer member 113, which is arranged at the sliding end position of the sliding block 1122. When the sliding block 1122 slides with the mounting rack 120 to the end position, the buffer member 113 buffers the sliding of the sliding block 1122, thereby buffering the mounting rack 120 and the adsorption assembly 140 thereon. It can be understood that in other embodiments of the present application, the buffer member 113 can also be arranged at the opposite ends of the extension arm 111 to buffer the sliding of the sliding block 1122 in two directions.

[0052] Optionally, the buffer 113 comprises a soft rubber block mounted on the extension arm 111, and the soft rubber block buffers the slider 1122. The soft rubber block can be made of rubber or silicone, for example. In other embodiments, the buffer 113 can also comprise a sponge or other elastic buffer structure.

[0053] In some embodiments, referring to Figure 7 , at least one end of the extension arm 111 is provided with a detection member 114 for detecting the mounting rack 120. Specifically, the opposite ends of the extension arm 111 are each provided with a detection member 114, and the printer further comprises a controller, and the detection member 114, the first driving mechanism 130 and the second driving mechanism 240 are respectively in communication connection with the controller. When the mounting rack 120 slides to the end of the extension arm 111, the detection member 114 feeds the position information of the mounting rack 120 to the controller, and the controller controls the start and stop of the first driving mechanism 130 and the second driving mechanism 240 according to the position information.

[0054] In some embodiments, referring to Figure 8 , the suction assembly 140 comprises a suction driving member 141 and a suction member 142, the suction driving member 141 is mounted on the mounting rack 120, and the suction member 142 is connected to the output end of the suction driving member 141. The suction driving member 141 is used to drive the suction driving member 141 to ascend and descend. When the guide rail beam 220, the mounting rack 120 and the suction assembly 140 are moved to above the medium by the second driving mechanism 240, the suction member 142 is lowered by the suction driving member 141 to adsorb the medium, then the printing platform 210 is conveyed along the first direction X to the end of printing 212 by the second driving mechanism 240 with the guide rail beam 220, the mounting rack 120, the suction member 142 and the medium, then the mounting rack 120, the suction member 142 and the medium are conveyed to above the cutting device 300 along the first direction X by the first driving mechanism 130, the suction member 142 releases the medium to the cutting device 300, and the suction driving member 141 drives the suction member 142 to ascend and reset.

[0055] Optionally, the suction driving member 141 comprises a linear cylinder or a linear motor or an electric push rod.

[0056] Optionally, the suction member 142 comprises a suction disc, the mounting rack 120 is formed with a fluid passage, each suction disc is in communication with the fluid passage through an air pipe, and the surface of the mounting rack 120 is provided with a joint 160 in communication with the fluid passage. The joint 160 is connected with a vacuum generator, and the vacuum generator is used to vacuumize the suction disc, so that the medium can be adsorbed. In addition, the mounting rack 120 is also provided with a solenoid valve, and the solenoid valve is used to control the on-off of the vacuum generator and the suction disc, so as to realize the adsorption and release of the medium.

[0057] In some embodiments, referring to Figure 8The mounting frame 120 is formed with a sliding groove 121 extending along the second direction Y, the adsorption assembly 140 is formed with a mounting groove 1433, and the first fasteners respectively penetrate the sliding groove 121 and the mounting groove 1433 to lock the adsorption assembly 140 to the mounting frame 120. Since the sliding groove 121 extends along the second direction Y, the mounting groove 1433 can be correspondingly locked at different positions along the second direction Y of the sliding groove 121, and the first fasteners can sequentially penetrate the sliding groove 121 and the mounting groove 1433 to lock the adsorption assembly 140 to different positions along the second direction Y of the mounting frame 120, so that the distance between adjacent adsorption assemblies 140 can be adjusted to meet the adsorption requirements of media of different weights, and the total length of each adsorption assembly 140 along the second direction Y can also be adjusted to adapt to media of different lengths. In addition, the adsorption assemblies 140 can be increased or decreased to meet the adsorption requirements of different media.

[0058] In some embodiments, referring to Figure 8 The mounting groove 1433 extends along the vertical direction, so that the mounting groove 1433 can be correspondingly locked at different positions along the vertical direction of the sliding groove 121 to adjust the position of the adsorption assembly 140 along the vertical direction on the mounting frame 120. Specifically, the mounting position of the adsorption assembly 140 along the vertical direction can be adjusted according to the thickness of different media to adapt to the adsorption requirements of media of different thicknesses. For example, the adsorption surface of the adsorption assembly 140 can be adjusted to be 10 mm away from the medium in the initial state, and the adsorption member 142 only needs to be driven downward by 10 mm by the adsorption driving member 141 each time to adsorb the medium.

[0059] Optionally, the mounting groove 1433 is a waist-shaped groove extending along the vertical direction. Specifically, the adsorption assembly 140 further includes a mounting seat 143, the adsorption driving member 141 is mounted to the mounting seat 143, and the waist-shaped groove is formed in the mounting seat 143. The adsorption member 142 is mounted to the mounting frame 120 through the mounting seat 143.

[0060] Specifically, the mounting seat 143 is L-shaped, and the mounting seat 143 includes a first mounting plate 1431 and a second mounting plate 1432 perpendicular to each other. Two waist-shaped grooves are formed on the first mounting plate 1431, and the two waist-shaped grooves are locked to the mounting frame 120 by the first fasteners. The adsorption driving member 141 is mounted to the second mounting plate 1432, and the adsorption member 142 is mounted to the output end of the adsorption driving member 141 and located between the first mounting plate 1431 and the second mounting plate 1432.

[0061] In some embodiments, the mounting rack 120 comprises an aluminum profile, and the sliding groove 121 is formed in the aluminum profile. The aluminum profile can be arranged to make the structure of the mounting rack 120 simple and the formation of the sliding groove 121 simple. It can be understood that, in other embodiments of the present application, the mounting rack 120 can also be a long strip-shaped plate structure, and the sliding groove 121 can be formed by machining, which is not limited herein.

[0062] After the assembly of the adsorption assembly 140 in the embodiments of the present application is completed, the guide rail beam 220 is first moved to the printing end 212 of the printing platform 210, so that the adsorption assembly 140 is located at the printing end 212 of the printing platform 210. Then, the position of the adsorption assembly 140 along the second direction Y is adjusted through the sliding groove 121 according to the width of the medium. Then, the adsorption driving member 141 is controlled to make the adsorption member 142 in a descending and negative pressure state. Then, the height of the adsorption member 142 is adjusted through the mounting groove 1433, so that the adsorption member 142 is in a flattening state, and the mounting seat 143 is locked to the mounting rack 120.

[0063] The above merely describes the preferred embodiments of the present application and is not intended to limit the present application. Any modification, equivalent replacement and improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application.
