[0036] In addition, the terms "first", "second" are only for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined with "first", "second" can explicitly or implicitly include one or more of the features. In some descriptions of the application, the meaning of "multiple" is two or more, unless otherwise specifically limited.

[0037] Referring to Figure 1 and Figure 2 A sheet feeding device, comprising a magazine mechanism 100, a rotating mechanism 200 and a feeding mechanism 300. Among them, the magazine mechanism 100 is used to place the sheet 130, the rotating mechanism 200 is used to enable the magazine mechanism 100 to rotate, and the feeding mechanism 300 is used to feed the sheet 130 in the magazine mechanism 100.

[0038] It can be understood that the magazine mechanism 100 can rotate specifically refers to that the magazine mechanism 100 can move in a cycle.

[0039] Further, the rotating mechanism 200 can include a support table 210 and a rotating drive structure 220, the rotating drive structure 220 is arranged on the support table 210, the support table 210 is provided with a rotating path connected head to tail, along the rotating path, a plurality of magazine mechanisms 100 are placed on the support table 210, and the rotating drive structure 220 can drive the magazine mechanism 100 to move on the rotating path. Among them, the rotating path connected head to tail enables the magazine mechanism 100 to realize circular motion on the support table 210.

[0040] The feeding mechanism 300 is arranged corresponding to the rotating path and can act on the sheet 130 in the magazine mechanism 100 to take out the sheet 130 from the magazine mechanism 100.

[0041] Specifically, the material box mechanism 100 located on the rotating path on the support platform 210 can be moved to the feeding mechanism 300 under the action of the rotating drive structure 220. The feeding mechanism 300 can take out the material pieces 130 in the material box mechanism 100 for feeding. It can be understood that after the material pieces 130 in the material box mechanism 100 located at the feeding mechanism 300 are fed, the rotating drive structure 220 can drive the empty material box mechanism 100 to rotate and disengage from the feeding mechanism 300. At the same time, the rotating drive structure 220 can drive the material box mechanism 100 filled with material pieces 130 to move to the feeding mechanism 300. The feeding mechanism 300 can continue to feed the material box mechanism 100 filled with material pieces 130, while the empty material box mechanism 100 can be replaced by a new material box mechanism 100 filled with material pieces 130.

[0042] As can be seen, the feeding device for the sheet 130 of this application is provided with a rotary mechanism 200. Multiple material box mechanisms 100 for placing the sheet 130 are placed on the rotation path of the support platform 210 in the rotary mechanism 200. Then, by providing a rotary drive structure 220 on the support platform 210, the material box mechanism 100 can be driven to rotate along the rotation path. The rotation path is also provided with a feeding mechanism 300. In this way, multiple material box mechanisms 100 can move sequentially to the feeding position. The feeding mechanism 300 feeds the sheet 130. So when the sheet 130 in the material box mechanism 100 located at the feeding mechanism 300 is finished, the next material box mechanism 100 filled with sheet 130 can be moved to the feeding mechanism 300, and the empty material box mechanism 100 can be replaced by a new material box mechanism 100 filled with sheet 130. This method can keep the sheet 130 feeding device running without stopping, and can continuously feed the sheet, thus improving the feeding efficiency of the sheet 130.

[0043] See Figure 1 and Figure 2 In one embodiment, the rotary drive structure 220 may include a first pusher 221, a second pusher 222, a third pusher 223, and a fourth pusher 224, which are respectively disposed on the support platform 210. The first pusher 221 pushes the material box mechanism 100 to move along a first direction, the second pusher 222 pushes the material box mechanism 100 to move along a second direction, the third pusher 223 pushes the material box mechanism 100 to move along a third direction, and the fourth pusher 224 pushes the material box mechanism 100 to move along a fourth direction. The first direction is perpendicular to the second direction, the third direction is opposite to the first direction, and the second direction is opposite to the fourth direction.

[0044] Understandably, the above method allows the material box mechanism 100 to rotate cyclically along the "U"-shaped structure. In other words, the support platform 210 can be set with a "U"-shaped rotation path.

[0045] Further, in order to improve the stability and precision of the rotation of the material box mechanism 100, the support table 210 is provided with a limiting groove 215 formed by the first groove wall 211, the second groove wall 212, the third groove wall 213, and the fourth groove wall 214. The material box mechanism 100 is placed in the limiting groove 215. The first groove wall 211 limits the movement of the material box mechanism 100 in the first direction. The second groove wall 212 limits the movement of the material box mechanism 100 in the second direction. The third groove wall 213 limits the movement of the material box mechanism 100 in the third direction. The fourth groove wall 214 limits the movement of the material box mechanism 100 in the fourth direction. The limiting effect of the first groove wall 211, the second groove wall 212, the third groove wall 213, and the fourth groove wall 214 forms a rotation path on the support table 210.

[0046] It can be understood that the first groove wall 211, the second groove wall 212, the third groove wall 213, and the fourth groove wall 214 can form a square limiting groove 215 on the support table 210. Multiple material box mechanisms 100 can be placed in the limiting groove 215. The material box mechanism 100 can move along the first groove wall 211, the second groove wall 212, the third groove wall 213, and the fourth groove wall 214 under the action of the first pushing element 221, the second pushing element 222, the third pushing element 223, and the fourth pushing element 224. Thus, the material box mechanism 100 can rotate in the rotation path formed by the first groove wall 211, the second groove wall 212, the third groove wall 213, and the fourth groove wall 214.

[0047] Further, in order to facilitate the movement of the material box mechanism 100 in the limiting groove 215 by the first pushing element 221, the second pushing element 222, the third pushing element 223, and the fourth pushing element 224, the material sheet 130 feeding device can be more compact.

[0048] The first pushing element 221 and the second pushing element 222 can be arranged on the support table 210 outside the first groove wall 211. The first groove wall 211 is provided with a first avoiding hole 216a and a second avoiding hole 216b. The first avoiding hole 216a extends in the first direction. The first pushing element 221 drives the material box mechanism 100 to move in the first direction through the first avoiding hole 216a. The second pushing element 222 drives the material box mechanism 100 to move in the second direction through the second avoiding hole 216b.

[0049] The third pushing member 223 and the fourth pushing member 224 are arranged on the support table 210 outside the third slot wall 213, the third slot wall 213 is provided with a third avoiding hole 216c and a fourth avoiding hole 216d, the third avoiding hole 216c extends along the third direction, the third pushing member 223 drives the magazine mechanism 100 to move along the third direction through the third avoiding hole 216c, and the fourth pushing member 224 drives the magazine mechanism 100 to move along the fourth direction through the fourth avoiding hole 216d.

[0050] It can be understood that, after the first pushing member 221, the second pushing member 222, the third pushing member 223 and the fourth pushing member 224 are arranged on one side of the first slot wall 211, the second slot wall 212, the third slot wall 213 and the fourth slot wall 214 respectively, the volume of the tablet 130 feeding device is expanded along the periphery, but the first pushing member 221 and the second pushing member 222 are arranged on the support table 210 outside the first slot wall 211, and the third pushing member 223 and the fourth pushing member 224 are arranged on the support table 210 outside the third slot wall 213, so that the volume of the tablet 130 feeding device is only expanded along two sides, and the first pushing member 221 can occupy a horizontal space with the second pushing member 222, and the third pushing member 223 can occupy a horizontal space with the fourth pushing member 224.

[0051] Further, the second slot wall 212 can be further provided with a fifth avoiding hole 216e for avoiding the first pushing member 221, and the fourth slot wall 214 can be further provided with a sixth avoiding hole 216f for avoiding the third pushing member 223.

[0052] It can be understood that the fifth avoiding hole 216e can make the first pushing member 221 push the magazine mechanism 100 to move along the first direction and retreat into the fifth avoiding hole 216e, so as to avoid the magazine mechanism 100 from interfering with the first pushing member 221 when the fourth pushing member 224 pushes other magazine mechanisms 100 to move along the fourth direction.

[0053] The sixth avoiding hole 216f can make the third pushing member 223 push the magazine mechanism 100 to move along the third direction and retreat into the sixth avoiding hole 216f, so as to avoid the magazine mechanism 100 from interfering with the third pushing member 223 when the second pushing member 222 pushes other magazine mechanisms 100 to move along the second direction.

[0054] Referring to Figure 1 and Figure 2In an embodiment, in order to further improve the stability and precision of the movement of the magazine mechanism 100, and to make the tray feeding device more compact, when one side of the magazine mechanism 100 abuts against one of the first slot wall 211, the second slot wall 212, the third slot wall 213 and the fourth slot wall 214, the other side of the magazine mechanism 100 opposite to the one side abuts against the side of the adjacent magazine mechanism 100 in the limiting slot 215.

[0055] It can be understood that when the magazine mechanism 100 moves along the rotation path, the magazine mechanism 100 can be accurately moved along the rotation path under the action of the first slot wall 211, the second slot wall 212, the third slot wall 213 and the fourth slot wall 214 and the adjacent magazine mechanism 100.

[0056] For example, in the limiting slot 215, the distance between the first slot wall 211 and the third slot wall 213 can accommodate two groups of magazine mechanisms 100, the distance between the second slot wall 212 and the fourth slot wall 214 can accommodate multiple groups of magazine mechanisms 100, and when multiple magazine mechanisms 100 are placed in the limiting slot 215, at least one space for the magazine mechanism 100 is reserved in the limiting slot 215. In this way, the structure of the sheet 130 feeding device can be compact, and more magazine mechanisms 100 can be rotated in the limiting slot 215 at the same time.

[0057] It can be understood that the space for the magazine mechanism 100 reserved in the limiting slot 215 can provide the magazine mechanism 100 with a movement space, facilitating the rotation of multiple magazine mechanisms 100 along the rotation path in turn.

[0058] Referring to Figures 2 to 4 In an embodiment, in order to facilitate the feeding mechanism 300 to take out the tray in the magazine mechanism 100, a first lifting hole 217 is arranged on the rotation path of the support table 210, the magazine mechanism 100 is provided with a cavity 123 for stacking the sheets 130, the bottom of the magazine mechanism 100 is provided with a second lifting hole 124 communicating with the cavity 123, and the top of the magazine mechanism 100 is provided with a discharge hole (not marked in the figure) communicating with the cavity 123.

[0059] The feeding mechanism 300 comprises a lifting structure arranged on the side of the support table 210 away from the magazine mechanism 100, and the lifting structure can sequentially pass through the first lifting hole 217 and the second lifting hole 124 to eject the sheet 130 in the cavity 123 from the discharge hole.

[0060] In an embodiment, the feeding mechanism 300 can further comprise a transfer structure arranged above the magazine mechanism 100, and the transfer structure is used for transferring the sheet 130 ejected from the discharge hole. The transfer structure can be a suction cup or the like for adsorbing the sheet 130.

[0062] It can be understood that the magazine mechanism 100 can accommodate more sheets 130, and the feeding mechanism 300 can simultaneously feed the sheets 130 in the plurality of magazines 120, thereby improving the feeding efficiency.

[0063] In addition, when the feeding of the sheets 130 in the magazine 120 is completed, the magazine 120 can be directly removed from the moving member 110 for replacement, and the moving member 110 can continuously remain on the rotating path, thereby facilitating the replacement of the new magazine 120 and continuously ensuring the accuracy of the movement of the moving member 110 on the rotating path.

[0064] Further, refer to Figure 4 In an embodiment, the magazine 120 comprises a frame 121 and a cover 122, the frame 121 is provided with a cavity 123, the bottom of the frame 121 is provided with a second lifting hole 124 communicating with the cavity 123, the top of the frame 121 is provided with a discharge hole communicating with the cavity 123, the side of the frame 121 is provided with an inlet hole (not shown in the figure) communicating with the cavity 123, and the cover 122 is detachably arranged on the side of the frame 121 to open or close the inlet hole.

[0065] Specifically, when it is needed to accommodate the sheets 130 in the cavity 123 of the frame 121, the cover 122 is removed from the frame 121, then the sheets 130 are accommodated in the cavity 123 through the inlet hole, and finally the cover 122 is arranged on the frame 121. The frame 121 and the cover 122 can be detachably connected by magnetic attraction.
