The carrier plate 121 is disposed between the two brackets 111, and the carrier plate 121 is a flat plate-shaped structure for carrying stacked printing media.

Then, the lifting motor can drive the two chain wheels 131 to move simultaneously, so that the two ends of the bearing platform 120 along the first direction X move synchronously in a lifting manner, thereby ensuring the stability of the bearing platform 120.

Further, in order to avoid the slide-down of the carrying platform 120 during the waiting process of the material taking step performed by the material taking module 140, the loading apparatus further includes a stopping module 160. Specifically, referring to fig. 4, which shows a partially enlarged schematic view of a portion in fig. 3, the anti-backup module 160 includes a base portion 161, a movable portion 162, an elastic member 163, and a pushing rod mechanism 164. To facilitate understanding of the overall structure and operation principle of the retaining module 160, the base 161, the movable portion 162, the elastic member 163 and the pushing rod mechanism 164 will be described in sequence.

The base 161 is fixed to the bracket 111 and extends in the lifting direction Z as a whole. The base 161 is provided with a plurality of retaining grooves 1611, and the plurality of retaining grooves 1611 are arranged at intervals in the vertical direction Z. The retaining groove 1611 is formed by a retaining surface 1612 and a guide slope surface 1613. The base 161 is provided with the retaining surface 1612 at one end of the retaining groove 1611 close to the bottom of the rack 110; the guiding inclined plane 1613 is inclined with respect to the lifting direction Z, one end of the guiding inclined plane is connected to the stopping surface 1612, the other end extends to one end of the base 161 close to the movable portion 162, and the stopping surface 1612 and the guiding inclined plane 1613 form an inverted 7-shaped opening together.

The movable portion 162 is disposed opposite to the base portion 161, and more specifically, opposite to the inclined guide surface 1613. The movable portion 162 is rotatably mounted to the mounting block 122 by a pin, not shown, the bottom of which is rotatably movable into and out of the retaining groove 1611.

In the elastic member 163 and the pusher mechanism 164, one end of the elastic member 163 is connected to the mounting block 122, the other end is connected to the movable portion 162, and the pusher mechanism 164 is mounted to the mounting block 122.

The push rod cylinder is used for abutting against the top of the movable part 162 through an expansion link when the expansion link of the push rod cylinder extends out, so as to drive the bottom of the movable part 162 to exit from the retaining groove 1611; at this time, the supporting platform 120 and the movable portion 162 can be driven by the lifting module 130 to be lifted normally.

It is understood that even though the elastic member 163 is a tension spring in this example, the present invention is not limited thereto, and in other embodiments of the present invention, the elastic member may be any structure capable of implementing the above-mentioned functions; for example: in some embodiments, the elastic member is a compression spring, one end of the compression spring is connected with the mounting block, and the other end of the compression spring is connected with the bottom of the movable part; in addition, the elastic element may also be an elastic element such as rubber, silica gel, etc., and the arrangement mode thereof may refer to a tension spring and a compression spring, which are not described herein.

Furthermore, in the utility model discloses an in other embodiments, can also get into the stopping groove through the bottom of push rod mechanism drive movable part to movable part, correspondingly, withdraw from the stopping groove through the bottom of elastic component drive movable part to movable part, its implementation is just opposite with the implementation of above-mentioned embodiment, no longer gives details here.

Referring to fig. 5, the material taking module 140 is shown in a schematic connection diagram of the material taking module 140, the material taking driving module 150 and the frame 110, and referring to fig. 1 to 4, the material taking module 140 is disposed above the carrying platform 120, and includes a first mounting beam 141, a mounting shaft 142, a mounting arm 143, a suction cup 144 and a material taking power mechanism 145. The first mounting beam 141 is disposed between the two brackets 111 and above the supporting platform 120, and extends along the first direction X, and two ends of the first mounting beam are respectively mounted on the brackets 111. In order to facilitate the installation of the first mounting beam 141, the frame 110 further includes two first fixing beams 113, the two first fixing beams 113 are respectively fixed to the two brackets 111, and two ends of the first mounting beam 141 are respectively in sliding fit with the two first fixing beams 113 along a second direction Y, where the second direction Y is a direction perpendicular to both the first direction X and the lifting direction Z. The mounting shaft 142 is disposed above the supporting platform 120, and extends along the first direction X, and two ends of the mounting shaft are rotatably mounted on the first mounting beam 141 respectively. The mounting arm 143 is disposed obliquely relative to the carrier plate 121, and has one end fixed to the mounting shaft 142 and the other end mounted with a suction cup 144; in this embodiment, the number of the mounting arms 143 and the suction cups 144 is plural, the plurality of mounting arms 143 are arranged at intervals along the first direction X, and the suction cups 144 are mounted on one mounting arm 143. The suction cup 144 is used for connecting with an external air suction device (not shown) which is used for sucking air in the material taking process, so that one end of the suction cup 144 close to the printing medium is in a negative pressure state, and the printing medium is convenient to be sucked; it will be appreciated that in some embodiments the charging means may also comprise the suction means described above. The material taking power mechanism 145 is connected to the mounting shaft 142, and is configured to drive the mounting shaft 142 to rotate, so as to drive the mounting arms 143 and the suction cups 144 to swing up and down, and further enable the suction cups 144 to press against the surface of the printing medium, so as to cooperate with the suction process of the suction device to achieve the material taking process. In this embodiment, the material extracting power mechanism 145 includes an extracting cylinder 1451 and a coupling arm 1452. The main body of the material taking cylinder 1451 is rotatably mounted on the first mounting beam 141, one end of the connecting arm 1452 is rotatably connected with the telescopic rod of the material taking cylinder 1451, and the other end is sleeved on the mounting shaft 142 and fixedly connected with the mounting shaft 142; thus, the body of the reclaiming cylinder 1451, the telescoping rod of the reclaiming cylinder 1451, the connecting arm 1452, and the first mounting beam 141 together form a crank rocker mechanism. Therefore, the mounting shaft 142 can be controlled to rotate by the extension and retraction of the telescopic rod of the material taking cylinder 1451, so as to drive the suction cup 144 to swing up and down. Certainly, in other embodiments of the present invention, the suction cup can be lifted through the cylinder and other structures to directly take the material, but when the material taking method is adopted, the two adjacent printing media on the top layer are always in whole surface contact, and the adsorption force between the two printing media is large; compared with the prior art, the material taking module 140 takes materials through the up-and-down swinging of the suction cup 144, and can turn over the top layer printing medium by taking one end far away from the suction cup 144 as an axis, so that the one end of the top layer printing medium is firstly separated from the printing medium below, and the air can conveniently flow into the space between the two printing media, thereby reducing or eliminating the adsorption force between the two printing media. In addition, the material taking module for taking materials through the lifting sucker has large displacement in the lifting direction Z, namely the occupied volume in the direction is large, which is not beneficial to the miniaturization of equipment; the material taking module 140 takes materials by rotating the mounting shaft 142 and the suction cup 144, and the displacement in the lifting direction Z is very small, i.e. the occupied volume is smaller, which is convenient for the miniaturization of the device. To accommodate different sized print media, the distance between adjacent suction cups 144 may be adjusted.

Referring to fig. 5, the material taking driving module 150 is further connected to the first mounting beam 141, and the material taking driving module 150 is used for driving the material taking module 140 to move and translate so that the material taking module 140 can convey the printing medium to a designated position, with reference to fig. 1 to 4.

Wherein, the synchronizing wheel group 151 comprises a plurality of synchronizing wheels 1511, and the plurality of synchronizing wheels 1511 are rotatably mounted on the first fixed beam 113. The two synchronizing wheel sets 151 are respectively disposed on the two first fixing beams 113, and a synchronizing wheel 1511 of one synchronizing wheel set is coaxially connected to a synchronizing wheel 1511 of the other synchronizing wheel set by a second connecting shaft 154 extending along the first direction X. The synchronous belts 152 are in one-to-one correspondence with the synchronous wheel sets 151, the synchronous belts 152 are wound around the synchronous wheels 1511 of the same synchronous wheel set 151, and both ends of the first mounting beam 141 are respectively fixed to the two synchronous belts 152. The output end of the carrying motor 153 is connected to the second connecting shaft 154, that is: the output end of the carrying motor 153 is indirectly connected to a synchronizing wheel 1511 (directly connected to the synchronizing wheel 1511 of the second connecting shaft) of the two synchronizing wheel sets 151 through the second connecting shaft 154, so as to drive the two synchronizing belts 152 to move, thereby driving the material taking module 140 to move. Alternatively, the timing belt 152 includes a portion extending in the second direction Y to which the first mounting beam 141 is fixed.

Further, in order to avoid the influence on the material taking process of the material taking module 140 caused by the two print media stacked up and down adjacently adsorbed together, the feeding device 100 further includes an air blowing module 170, and the air blowing module 170 is configured to blow air to the print media when the print media are loaded on the loading plate 121, so that air flows enter between the adjacent print media, and thus, the adsorption force between the print media is reduced or eliminated. Specifically, referring to fig. 6, which shows a partially enlarged schematic view at B in fig. 1, the air blowing module 170 includes an air nozzle 171 and an air blowing mechanism (not shown); the air nozzle 171 is arranged on the connecting beam 112, and the opening of the air nozzle 171 faces the accommodating space; the blowing mechanism is connected to an air nozzle 171 for blowing out the air flow.

The second mounting beam 181 extends along the first direction X, and two ends of the second mounting beam 181 are respectively mounted to the frame 110 and slidably engaged with the frame 110 along the second direction Y, so that the second mounting beam 181 can be close to or far from the air nozzle 171. In this embodiment, in order to facilitate the installation of the second mounting beam 181, the frame 110 further includes two second fixing beams 114, the two second fixing beams 114 are respectively and fixedly installed on the two brackets 111, and two ends of the second mounting beam 181 are respectively and slidably installed on the two second fixing beams 114 and are in sliding fit with the second fixing beams 114 along the second direction Y. The alignment baffle 182 has a flat plate-like structure as a whole, and is disposed opposite to each air nozzle 171. The alignment drive mechanism 183 is connected to the alignment flap 182, and drives the alignment flap 182 to move up and down in the up-and-down direction Z, so that the alignment flap 182 moves to correspond to the top printing medium. Optionally, the alignment driving mechanism 183 is an alignment cylinder, a main body of the alignment cylinder is fixed to the second mounting beam, and a telescopic rod of the alignment cylinder is connected with the alignment baffle 182; it is understood that in other embodiments of the present invention, the regulation driving mechanism may also be any other structure capable of driving the regulation baffle to move up and down, such as a motor-screw assembly. Further optionally, a spring 185 is sleeved on the telescopic rod of the leveling cylinder, two ends of the spring 185 respectively abut against the leveling baffle 182 and the main body of the leveling cylinder, and the arrangement of the spring 185 can play a role in buffering when the leveling baffle 182 is pressed down to the surface of the tray 123, so as to prevent the leveling baffle 182 from overshooting to damage the tray 123 or the tray itself. A locking mechanism 184 is mounted to the second mounting beam 181 for timely locking and securing the second mounting beam 181 to the second fixed beam 114.

In this embodiment, the partition 191 is rotatably mounted on one of the connecting beams 112, the partition driving module 192 is a partition cylinder, the main body of the partition cylinder is rotatably mounted on the other connecting beam 112, and the expansion link of the partition cylinder is rotatably connected with the partition 191; the main body of the partition cylinder, the expansion rod of the partition cylinder, the partition 191 and the frame 110 together form a crank rocker mechanism, and the expansion and contraction of the expansion rod can control the partition 191 to rotate relative to the connecting beam 112, so that the partition 191 enters and exits the accommodating space. When carrying out two print media material loading processes, baffle actuating mechanism drive baffle 191 gets into accommodating space, then the staff can settle this two pile of print media in the both sides of baffle 191 respectively to make this two pile of print media carry out preliminary positioning, avoid influencing follow-up conveying process on conveyor because two pile of print media are irregularly placed.

The following will briefly describe the working process of the feeding device provided by the embodiments of the present invention with reference to the accompanying drawings.

When a single-stack printing medium loading process is required, firstly, the tray 123 and the printing medium are loaded on the loading platform 120; then, the lifting module 130 drives the carrying platform 120 to ascend until the uppermost printing medium approaches the suction cup 144; then, the material taking power mechanism 145 drives the mounting shaft 142 to rotate, the suction cup 144 presses down and adsorbs the uppermost printing medium, and the material taking power mechanism 145 drives the mounting shaft to reset; next, the material taking driving module 150 drives the material taking module 140 to move to the upper part of the external conveying device (for example, the upper part of the conveying roller), the material taking power mechanism 145 drives the mounting shaft 142 to rotate, and the suction cup 144 presses down and releases the printing medium; then, the material taking power mechanism 145 is reset, and the material taking driving module 150 drives the material taking module 140 to reset, so as to perform the next feeding process of the printing medium. It should be noted that, since the height of the stacked print media is changed in the material taking process, after each time the loading of a print medium is completed, the lifting module 130 drives the supporting platform 120 to rise by a set height, so as to adapt to the loading process of the next print medium.

The process of feeding a double stack of printing media is substantially the same as the above-described process of feeding a single stack, with the main differences being: before the printing media are placed, the partition 191 is driven by the partition driving mechanism 192 to at least partially extend into the accommodating space, and then two stacks of printing media are placed on two sides of the partition 191 respectively. The following working process is the same as the above-mentioned feeding process of the single-stack printing medium, and is not described herein again.

The embodiment of the utility model provides a loading attachment 100 includes frame 110, load-bearing platform 120, lifting module 130, gets material module 140 and gets material drive module 150. Wherein the carrier platform 120 is used to carry media. The lift module 130 is configured to drive the carriage 120 up and down to bring the media adjacent to the extraction module 140. The material taking module 140 is disposed above the supporting platform 120, and includes a first mounting beam 141, a mounting shaft 142, a suction cup 144 and a material taking power mechanism 145, wherein the material taking module 140 can drive the mounting shaft 142 to rotate through the material taking power mechanism 145, and further drive the suction cup 144 to swing up and down, so as to take materials from the stacked media one by one from top to bottom. Namely: the feeding device 100 is suitable for a top-down feeding mode, has no special requirements on the stacking number of printing media, and can effectively avoid the technical problem that the bottom layer media are easily damaged or drawn and pulled immovable due to the fact that the existing feeding device adopts a downward-drawing feeding mode.

It is to be noted that "a plurality" in the present invention means two or more.

Based on the same inventive concept, the utility model also provides a printing device, this printing device includes loading attachment 100 that the above-mentioned embodiment provided, so this printing device also can effectively solve the technical problem that the bottom printing medium that the traditional material loading mode of drawing down leads to receives the damage easily.
