[0022] 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.

[0023] like Figure 1-Figure 4 As shown, this example provides a feeding device for cardboard processing, including: a support platform 100, a bearing mechanism 200, and a pushing mechanism 300.

[0024] A carrier frame 101 is provided below the support platform 100, and a recessed portion 102 penetrating from top to bottom is provided on the top surface of one end of the support platform 100; a carrier mechanism 200 is installed on the carrier frame 101, including a carrier plate 201 that moves in the vertical direction. When the cardboard needs to be pushed, the carrier plate 201 is located in the recessed portion 102, and a material frame 202 is provided on the carrier plate 201 for carrying the cardboard. Limiting plates 203 that are symmetrically arranged and move toward each other are provided on both sides of the carrier plate 201 for limiting the material frame 202, and a top plate 204 that moves in the vertical direction is provided between the limiting plates 203 for lifting the cardboard; a pushing mechanism 300 is installed on the support platform 100, including two pressing plates 301 that are symmetrically arranged above the support platform 100 and move in the vertical direction, and a first pushing plate 302 that moves along its length direction is provided between the pressing plates 301 for pushing the cardboard.

[0025] Specifically, spacers 205 are provided around the bottom surface of the carrying plate 201, which are used to abut against the bottom surface of the support platform 100 to prevent the carrying plate 201 from moving upward too much. The spacers 205 are connected to the moving end of the vertical lifting mechanism, and the vertical lifting mechanism is installed on the carrying frame 101. A groove 103 is provided on the top surface of the carrying frame 101. The groove 103 coincides with the projection of the recessed portion 102 in the vertical direction. When the material frame 202 is moved onto the carrying plate 201, the spacers 205 are located in the groove 103. At this time, the top surface of the carrying plate 201 is flush with the top surface of the lower end of the carrying frame 101.

[0026] Specifically, the carrier 101 is provided with a through slot 104 running through it from top to bottom along its length direction, one end of the through slot 104 is connected to the groove 103, a push block 105 is passed through the through slot 104, the upper end of the push block 105 is arc-shaped away from the side of the carrier 101, the lower end of the push block 105 is passed through the moving frame 106, and a connecting plate 107 is provided, and a top rod 108 is provided on the bottom surface of the connecting plate 107, and the top rod 108 is passed through the moving frame 106, and the moving frame 106 is connected to the moving end of the first horizontal linear mechanism, and the horizontal linear mechanism is installed on the bottom surface of the carrier 101, and a first spring 109 is sleeved on the top rod 108, and the two ends of the first spring 109 are respectively abutted against the moving frame 106 and The connecting plate 107 is always in a compressed state. When the material frame 202 is placed on the carrier 101, the edge of the material frame 202 will contact the arc surface of the push block 105. As the material frame 202 moves toward the center of the carrier 101, the push block 105 will be forced to move downward, and the first spring 109 will be further compressed until the material frame 202 completely passes through the push block 105. The push block 105 will pop out under the action of the first spring 109, and then the spacer bar 205 is located in the groove 103. The push block 105 can be driven to move toward the center of the carrier 101 through the first horizontal linear mechanism, thereby pushing the material frame 202 onto the carrier plate 201.

[0027] Specifically, in order to ensure that after the material frame 202 is pushed onto the carrier plate 201, the material frame 202 is located at the center of the carrier plate 201, clamps 110 are provided on both sides of the length direction of the carrier frame 101, and the lower end of the clamp 110 passes through the carrier frame 101 and is connected to the moving end of the bidirectional linear mechanism. The bidirectional linear mechanism is installed at the bottom of the carrier frame 101. The two clamps 110 are driven to move toward each other through the bidirectional linear mechanism, so that the position of the material frame 202 can be adjusted, and the two limit plates 203 can also be connected to the moving end of a bidirectional linear mechanism, so that the material frame 202 can be limited.

[0028] Specifically, in order to facilitate pushing the cardboard in the material frame 202, a through hole 206 is provided in the center of the carrier plate 201 and the material frame 202. The top plate 204 is located in the through hole 206 and is connected to the movable end of the telescopic rod 207. The telescopic rod 207 is installed at the bottom of the carrier plate 201. When in use, the telescopic rod 207 is used to lift the cardboard by a distance of the thickness of the cardboard, so that the top cardboard is moved out of the material frame 202.

[0029] Specifically, in order to prevent the material frame 202 from moving too far when being moved onto the supporting plate 201, a slide groove 208 is provided on the top surface of one end of the supporting plate 201 away from the center of the support platform 100, and a guide rod 209 is provided in the slide groove 208. A baffle 210 is passed through the slide groove 208, and the baffle 210 is sleeved on the guide rod 209 and locked with a nut to abut against the material frame 202, so that the material frame 202 can be located at the center of the supporting plate 201, ensuring that the through holes 206 of the supporting plate 201 and the material frame 202 can be aligned.

[0030] Specifically, a second push plate 306 is further provided on one end of the support platform 100 close to the recessed portion 102. The second push plate 306 is connected to the movable end of the third horizontal linear mechanism. The third horizontal linear mechanism is installed on the support platform 100. The second push plate 306 can be moved by being driven by the third horizontal linear mechanism, so that the material frame 202 on the supporting plate 201 is pushed onto the support platform 100. A notch 307 is provided on the side of the second push plate 306 for passing through the baffle 208 to prevent the baffle 208 from blocking the smooth movement of the second push plate 306.

[0031] Specifically, when the carrying plate 201 is located in the recessed portion 102, the distance between the bottom surface of the pressing plate 301 and the top of the material frame 202 is the thickness of a cardboard. The pressing plate 301 is L-shaped, and both ends are sleeved on the screw 303, the screw 303 is installed on the side plate 304, and the side plate 304 is installed on the support platform 100. The screw 303 is sleeved with a second spring 305 and a nut, and the nut abuts against the top surface of the pressing plate 301. The two ends of the second spring 305 abut against the side plate 304 and the pressing plate 301 respectively, and are always in a compressed state. By turning the nut, the height of the pressing plate 301 can be adjusted. When the top plate 204 pushes the cardboard upward, the pressing plate 301 abuts against the topmost cardboard, thereby preventing the top plate 204 from moving the cardboard upward too far.

[0032] Specifically, the first push plate 302 is connected to the moving end of the second horizontal linear mechanism, and the second horizontal linear mechanism is installed on one of the pressing plates 301 . The first push plate 302 is driven to move by the second horizontal linear mechanism to push the cardboard out of the material frame 202 .
