[0020] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings, but the embodiments described in the utility model are only part of the embodiments of the utility model, rather than all the embodiments.

[0021] like Figure 1-Figure 4 As shown, this example provides a cardboard automatic stacking device, which is arranged at the conveying end of the conveyor belt, and includes: a workbench 100, a temporary storage mechanism 200, and a transfer mechanism 300.

[0022] Two protrusions 101 are provided on the side of the workbench 100 away from the conveyor belt. The temporary storage mechanism 200 is installed on the workbench 100, including a support plate 201 that moves back and forth along the length direction of the workbench 100. Three convex strips 202 are provided on the support plate 201 along its length direction. Two symmetrically arranged and mutually moving limiting plates 203 are provided between two adjacent convex strips 202. Cardboard is placed between the limiting plates 203. A baffle 204 that moves in the vertical direction is provided between the limiting plates 203 and is used to abut against the cardboard. The transfer mechanism 300 includes two material frames 301 respectively provided on the protrusions 101 and a push plate 302 located on the side of the workbench 100 close to the conveyor belt. The push plate 302 is used to push the cardboard from the limiting plates 203 to the material frame 301.

[0023] Specifically, two through holes 205 are provided on the side of the support plate 201 away from the conveyor belt, and the baffle plate 204 is inserted into the through holes 205. The lower end of the baffle plate 204 abuts against the top surface of the workbench 100, and two through grooves 103 are provided on the side of the workbench 100 away from the conveyor belt. A top block 206 is provided in the through groove 103. When in use, the top surface of the top block 206 is flush with the top surface of the workbench 100, and the lower end of the top block 206 is connected to the lifting plate 207, and the lifting plate 207 is connected to the moving end of the vertical lifting mechanism. The vertical lifting mechanism is installed on the workbench 100. At the bottom of the workbench 100, after a certain amount of cardboard is stored between the two limit plates 203, the support plate 201 can be moved so that a part of it carrying the cardboard is moved to one side of the protruding portion 101. At this time, one of the baffles 204 is located directly above the top block 206. The lifting plate 207 is driven downward by the vertical lifting mechanism, and the baffle 204 will also move downward and enter the through groove 103. Then, the cardboard on the support plate 201 can be pushed into the material frame 301 by the push plate 302.

[0024] Specifically, a plurality of slide grooves 208 are provided on the support plate 201 along its length direction, and the slide grooves 208 are respectively located between two adjacent convex strips 202. The lower end of the limit plate 203 passes through the slide groove 208 and is connected to the moving end of the first bidirectional linear mechanism. The first bidirectional linear mechanism is installed at the bottom of the support plate 201. The two limit plates 203 can be driven to move towards each other or in opposite directions at the same time through the first bidirectional linear mechanism, so as to adapt to cardboards of different sizes.

[0025] Specifically, the push plate 302 is connected to the moving end of the telescopic rod 303 , the telescopic rod 303 is mounted on the vertical plate 102 , and the vertical plate 102 is mounted on the workbench 100 . The push plate 302 is driven to move by the telescopic rod 303 , thereby pushing the cardboard into the material frame 301 .

[0026] Specifically, a stopper 104 is provided on the side of the protrusion 101 close to the workbench 100, which is used to abut against one side of the material frame 301. When the material frame 301 is placed on the protrusion 101, the material frame 301 is prevented from intruding into the area of ​​the workbench 100, thereby limiting the movement of the support plate 201, and the top surface of the stopper 104 is flush with the top surface inside the material frame 301 to avoid interfering with the normal pushing of the cardboard.

[0027] Specifically, in the process of pushing the cardboard to the material frame 301, in order to prevent the material frame 301 from moving due to the friction force, a long hole 105 is provided along the width direction of the protruding portion 101, and the length direction of the long hole 105 is parallel to the width direction of the workbench 100. A card block 106 is passed through the long hole 105, and one side of the card block 106 is in contact with the material frame 301. The side of the card block 106 away from the workbench 100 is arc-shaped, and the lower end is passed through the moving frame 107. The moving frame 107 is connected to the moving end of the horizontal linear mechanism. The horizontal linear mechanism is installed at the bottom of the protruding portion 101. A bottom plate 108 is provided at the lower end of the card block 106, and the bottom surface of the bottom plate 108 A push rod 109 is provided, and the push rod 109 is passed through the lower end of the moving frame 107. A spring 110 is sleeved on the push rod 109. The two ends of the spring 110 are respectively abutted against the bottom plate 108 and the moving frame 107, and are always in a compressed state. The moving frame 107 is driven to move toward the workbench 100 through a horizontal linear mechanism, and then the material frame 301 can be placed on the protruding portion 101. At this time, the block 106 will be pressed into the long hole 105, and the spring 110 will be further compressed until the material frame 301 is completely moved between the stop block 104 and the block 106. At this time, the block 106 will also pop up under the action of the spring 100 to achieve the limitation of both sides of the material frame 301.

[0028] More specifically, limiting grooves 111 parallel to the length direction are respectively provided at both ends of the length direction of the protrusion 101, and a positioning plate 112 is passed through the limiting groove 111. The lower end of the positioning plate 112 is connected to the moving end of the second bidirectional linear mechanism. The second bidirectional linear mechanism is installed at the bottom of the protrusion 101. The second bidirectional linear mechanism can drive the two positioning plates 112 to move toward each other at the same time until they abut against the end of the material frame 301, thereby achieving the limitation of the material frame 301.

[0029] Since the above are only preferred embodiments of the present invention and are not intended to limit the present invention, it is obvious that those skilled in the art can make various modifications and variations to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
