Description

Technical Field

[0001] This utility model relates to the technical field of grinding, and in particular to a grinding device for the cutting edge of a paper product die. Background Technology

[0002] Paper product die cutting is a device used to cut paper. During the production of the die cutting, the mold of the required shape is first made, and then steel blades are precisely arranged at the bottom of the mold to obtain the die cutting. During long-term use, the blade of the die cutting will wear down, resulting in a reduction in its cutting effect, so the blade surface of the die cutting needs to be ground. In the prior art, a utility model patent with patent application number 202021732269.6 discloses a cardboard cross-cutting knife blade grinding device, which mainly consists of a worktable, a grinding head, and a fixed frame. When grinding the blade surface, the blade is fixed on the worktable, and then the grinding head is driven by a motor to rotate, so that the grinding head contacts the blade surface and grinds the blade surface. However, it has the following problems in use: since the blade angle is different on different types of die-cutting molds, the angle of the grinding head on the above-mentioned grinding device cannot be changed. Therefore, it can only grind die-cutting molds with one blade angle, which has high limitations and is inconvenient to use. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a paper product die-cutting surface grinding device that can adjust the angle of the grinding wheel according to the angle of the blade, can grind blades at different angles, is easy to use, has low limitations, and is highly practical.

[0004] This utility model discloses a grinding device for the cutting edge of paper product die-cutting molds, comprising a base plate, a worktable, and a clamping mechanism, the clamping mechanism being mounted on the worktable. It also includes a lifting mechanism, a moving mechanism, an angle adjustment mechanism, and a grinding mechanism. The worktable is mounted on the base plate via the lifting mechanism, which is used to raise and lower the worktable. The angle adjustment mechanism is mounted on the moving mechanism, which is used to move the angle adjustment mechanism. The grinding mechanism is mounted on the angle adjustment mechanism, which is used to adjust the angle of the grinding mechanism. The grinding mechanism is equipped with a grinding wheel and performs grinding functions. The clamping mechanism can be a three-jaw chuck, flat-jaw pliers, or a vise. A suitable clamping mechanism can be selected and mounted on the worktable according to the shape of the die-cutting mold. When grinding the cutting edge of the die... During grinding, the die is clamped and fixed by a clamping mechanism. Then, a lifting mechanism adjusts the height of the worktable and clamping mechanism, thereby adjusting the cutting edge on the die to a suitable grinding height. Next, the angle adjustment mechanism adjusts the angle of the grinding mechanism according to the angle of the cutting edge on the die, so that the angle of the grinding wheel on the grinding mechanism matches the angle of the cutting edge on the die. Then, the grinding mechanism is opened, causing the grinding wheel to rotate. A moving mechanism brings the rotating grinding wheel into contact with the cutting edge on the die, and the rotating grinding wheel grinds the cutting edge on the die until it is sharp. It can adjust the angle of the grinding wheel according to the angle of the cutting edge, and can grind cutting edges at different angles. It is convenient to use, has few limitations, and is highly practical.

[0005] Preferably, the lifting mechanism includes a hydraulic cylinder, a push rod, a fixed column, and a sliding column. The hydraulic cylinder is fixedly mounted on the base plate, and a push rod is provided at the output end of the hydraulic cylinder. The fixed column is fixedly mounted on the base plate, and the lower part of the sliding column is slidably mounted on the fixed column. The worktable is fixedly mounted on the upper end of the push rod and the sliding column. When the blade of the die is being sharpened, the hydraulic cylinder is opened, and the hydraulic cylinder adjusts the height of the worktable through the push rod. The worktable adjusts the height of the die through the clamping mechanism until the blade on the die is adjusted to a suitable height for sharpening. This facilitates the sharpening of the blade on the die.

[0006] Preferably, the moving mechanism includes a bracket, an electric slide rail A, a sliding plate, a support frame, an electric slide rail B, and a sliding plate. The electric slide rail A is fixedly mounted on the base plate via the bracket, and the sliding plate is mounted on the electric slide rail A. The electric slide rail A is used to move the sliding plate back and forth. The support frame is fixedly mounted on the upper part of the sliding plate, and the electric slide rail B is fixedly mounted on the upper part of the support frame. The sliding plate is mounted on the electric slide rail B, and the electric slide rail B is used to move the sliding plate left and right. An angle adjustment mechanism is mounted on the sliding plate. When the die is being polished by the polishing mechanism, the electric slide rail A is opened. The electric slide rail A, through the sliding plate, allows the support frame to move the electric slide rail B and the sliding plate back and forth. The electric slide rail B allows the sliding plate to move left and right. Since the sliding plate can move back and forth and left and right, the angle adjustment mechanism allows the polishing mechanism to move back and forth and left and right. The position of the polishing mechanism can be adjusted according to the position of the cutting edge on the die, facilitating the polishing of the cutting edge on the die.

[0007] Preferably, the angle adjustment mechanism includes a mounting plate, a motor A, a roller, and a connecting block. The mounting plate is fixedly mounted on the lower end of the sliding plate, the motor A is fixedly mounted on the mounting plate, the roller is rotatably mounted on the mounting plate, the input end of the roller is connected to the motor A, the connecting block is fixedly mounted on the roller, and the angle adjustment mechanism is mounted on the connecting block. The motor A is a stepper motor with angle self-locking capability. When adjusting the angle of the grinding wheel, the motor A is turned on, and the motor A drives the roller to rotate, which in turn drives the connecting block to rotate the grinding mechanism, causing the grinding mechanism to adjust its angle until the angle of the grinding wheel on the grinding mechanism is adjusted to a suitable grinding angle. This facilitates the adjustment of the grinding wheel angle.

[0008] Preferably, the grinding mechanism includes a mounting frame, a motor B, and a rotating shaft. The mounting frame is fixedly mounted on the connecting block, the motor B is fixedly mounted on the mounting frame, and the rotating shaft is rotatably mounted on the mounting frame. The upper end of the rotating shaft is connected to the output end of the motor B, and the grinding wheel is fixedly mounted on the lower end of the rotating shaft. When grinding the die with the grinding wheel, the motor B is turned on, and the motor B rotates the grinding wheel through the rotating shaft, so that the rotating grinding wheel contacts the cutting edge on the die. The cutting edge of the die is then ground by the rotating grinding wheel, which improves convenience.

[0009] Preferably, a lighting lamp is provided on the base plate; this arrangement makes the area above the base plate brighter, facilitating observation of the grinding operation.

[0010] Preferably, a cooler is provided on the base plate, and an exhaust pipe is provided on the cooler. The exhaust pipe is a flexible exhaust pipe. When grinding the blade of the die, if the temperature is too high during the grinding process, the cooler is turned on, and the worker holds the exhaust pipe and blows air onto the grinding wheel to promote heat dissipation of the grinding wheel and ensure the grinding effect of the grinding wheel.

[0011] Compared with the prior art, the advantages of this utility model are: the angle of the grinding wheel can be adjusted according to the angle of the blade, and blades at different angles can be ground. It is convenient to use, has low limitations, and is highly practical. Attached Figure Description

Then, the angle adjustment mechanism adjusts the angle of the grinding mechanism according to the angle of the blade on the die 22, so that the angle of the grinding wheel 4 on the grinding mechanism matches the angle of the blade on the die 22. Then, the grinding mechanism is opened, and the grinding wheel 4 is rotated. Then, the moving mechanism makes the rotating grinding wheel 4 contact the blade on the die 22, and the rotating grinding wheel 4 grinds the blade on the die 22 until the blade on the die 22 is sharpened.

On the sliding plate 14; when the die 22 is being polished by the polishing mechanism, the electric slide rail A10 is opened. The electric slide rail A10, through the sliding plate 11, can cause the support frame 12 to move the electric slide rail B13 and the sliding plate 14 back and forth. The electric slide rail B13 can cause the sliding plate 14 to move in the left and right directions. Since the sliding plate 14 can move back and forth and left and right, the sliding plate 14 can be adjusted by the angle adjustment mechanism to make the polishing mechanism move back and forth and left and right.
