[0020] The first motor 314 drives the bidirectional lead screw 315 to rotate forward, driving the two clamping plates 305 to approach along the direction of the first limiting rod 316, clamping and fixing the edge of the cardboard placed on the supporting plate 320, avoiding the offset of the cardboard during the grinding process. The third cylinder 317, in cooperation with the lower pressing plate 318 and the supporting plate 320, can clamp and fix the upper and lower ends of the cardboard. When it is necessary to grind the edges of the cardboard in other directions, the first motor 314 drives the bidirectional lead screw 315 to rotate in reverse, the two clamping plates 305 move away from the cardboard, and the second motor 319 drives the supporting plate 320 to adjust the position of the cardboard. During the adjustment process, the lower pressing plate 318 rotates following the cardboard, and at the same time, the cardboard can be fixed.

[0021] As Figure 2 shown, the corner clamping assembly includes two mounting rods 313 symmetrically arranged on the mounting plate 301. The bottom end of the mounting rod 313 is fixedly connected to the mounting plate 301, and the top end of the mounting rod 313 is fixedly connected to the first connecting plate 303. Two clamping strips 310 are installed on the outer side of the mounting rod 313. A first mounting block 312 is installed at the connection between the clamping strip 310 and the mounting rod 313. A second cylinder 309 is installed between the center of the bottom end of the lower clamping strip 310 and the mounting plate 301. A first cylinder 308 is installed in the center of the upper end of the upper clamping strip 310. The housing of the first cylinder 308 is fixedly connected to the first connecting plate 303. By driving the clamping strips 310 to move along the direction of the mounting rod 313 respectively through the first cylinder 308 and the second cylinder 309, the grinding end of the cardboard can be clamped by the two clamping strips 310, avoiding the offset of the grinding position caused by the deformation of the cardboard.

[0022] As Figures 1-3 shown, second mounting blocks 322 are respectively installed on both sides near the bottom end of the mounting plate 301. A second limiting rod 321 is installed through the front and rear ends of the second mounting block 322. Both ends of the second limiting rod 321 are fixedly connected to the bottom plate 1 through connecting parts. A fourth cylinder 323 is installed in the center of the upper end of the bottom plate 1. The telescopic end of the fourth cylinder 323 is fixedly connected to the bottom end of the mounting plate 301. The fourth cylinder 323 pushes the mounting plate 301 to move along the direction of the second limiting rod 321 through the second mounting block 322, thereby driving the cardboard to move towards the grinding machine 2.

[0023] As Figure 2As shown in the figure, an installation groove is provided at the rear end of the clamping plate 305. An installation strip 306 is installed in the installation groove. Through slots 311 are respectively provided at the upper and lower ends of the clamping strip 310 and near both ends. The installation strip 306 is movable in the through slots 311. A limit block 307 is installed at the outer side of the installation strip 306 near the bottom end. When the upper end of the lower clamping strip 310 contacts the limit block 307, the upper end of the lower clamping strip 310 is flush with the upper end of the supporting plate 320. By providing the installation strip 306, the clamping plate 305 and the clamping strip 310 can be further limited, reducing the deformation of the clamping strip 310 when fixing the cardboard. By providing the limit block 307, the lower clamping strip 310 can be limited to avoid over-compressing the cardboard and maintaining the flatness of the cardboard.

[0024] All standard parts used in the present utility model can be purchased from the market. The special-shaped parts can be customized according to the description in the specification and the drawings. The specific connection methods of each part all adopt conventional means such as bolts, rivets, and welding that are mature in the prior art. The machines, parts, and equipment all adopt conventional models in the prior art. Coupled with the circuit connection adopting the conventional connection method in the prior art, details are not described herein again.

[0025] Meanwhile, the content not described in detail in this specification belongs to the well-known prior art to those skilled in the art.

[0026] The implementation principle of a cardboard edge grinding device according to an embodiment of the present application is as follows:

[0027] When the cardboard is placed on the supporting plate 320, start the first motor 314 to drive the bidirectional lead screw 315 to rotate forward. The bidirectional lead screw 315 drives the clamping plate 305 to approach the cardboard along the direction of the first limiting rod 316, clamping the edge of the cardboard. At the same time, the upper end of the third cylinder 317 contacts the cardboard through the lower pressing plate 318, further clamping and fixing the upper and lower ends of the cardboard to ensure the stability of the cardboard during the grinding process. The first cylinder 308 and the second cylinder 309 respectively drive the two clamping strips 310 to move along the direction of the mounting rod 313 until the two clamping strips 310 tightly clamp the grinding end of the cardboard, avoiding deformation and offset during the grinding process. After the cardboard is firmly clamped, the fourth cylinder 323 pushes the mounting plate 301 to move towards the grinding machine 2 along the direction of the second limiting rod 321, driving the cardboard to move towards the grinding machine 2. Start the grinding machine 2 to grind the edge of the cardboard. If it is necessary to adjust the grinding position, the first cylinder 308 and the second cylinder 309 drive the clamping strip 310 away from the cardboard to avoid the clamping strip 310 contacting the cardboard and causing the cardboard to shift when adjusting the position. The bidirectional lead screw 315 can be controlled by the first motor 314 to reverse, releasing the clamping plate 305. Subsequently, use the second motor 319 to adjust the position of the cardboard on the supporting plate 320. At the same time, the lower pressing plate 318 rotates with the cardboard and continues to be fixed to ensure the stability during the adjustment process. After the grinding is completed, the bidirectional lead screw 315 is controlled by the first motor 314 to reverse again to release the clamping plate 305. At the same time, the third cylinder 317 retracts to release the clamping of the upper and lower ends of the cardboard. The clamping strip 310 also returns to the initial position through the drive of the first cylinder 308 and the second cylinder 309, releasing the cardboard and completing the entire grinding process.
