DETAILED DESCRIPTION

[0020] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0021] like Figure 1-4 As shown, the utility model provides a technical solution: a cutting device for paper box manufacturing, including a base 1, a cutting platform 2 is fixedly installed on the top of the base 1, an adjusting frame 3 is fixedly installed on one side of the cutting platform 2, an adjusting screw 301 is rotatably installed at the central position of the bottom of the adjusting frame 3, and one end of the adjusting screw 301 passes through the adjusting frame 3 and is fixedly installed with an adjusting knob 302, and the bottom of the adjusting frame 3 is symmetrically fixedly installed with limiting slide bars 303 on both sides of the adjusting screw 301. By providing the adjusting screw 301, turning the adjusting knob 302 drives the adjusting screw 301 to rotate, thereby controlling the movable top plate 304 to move closer to or away from the cutting knife 504 on the surface of the adjusting screw 301.

[0022] A movable top plate 304 is slidably installed on the surface of the adjusting screw 301 and the two sets of limiting slide bars 303, and the top of the movable top plate 304 passes through the adjusting frame 3, and an adjusting spring 305 is provided on the surface of the limiting slide bar 303 located on the side of the movable top plate 304 close to the adjusting knob 302. Because of the limiting slide bar 303 and the adjusting spring 305, the two ends of the movable top plate 304 will not tilt and get stuck when sliding on the surface of the limiting slide bar 303 under the rebound action of the adjusting spring 305.

[0023] Electric push rods 4 are fixedly installed on both sides of the top of the base 1, and the tops of the two groups of electric push rods 4 pass through the cutting platform 2 and are fixedly installed with a fixing plate 5, and three groups of fixing rods 501 are equidistantly slidably installed on the bottom of the fixing plate 5, and a knife holder 503 is fixedly installed on the bottom of the three groups of fixing rods 501. A cutting knife 504 is provided at the bottom of the knife holder 503, and the bottom of the cutting knife 504 is inclined. By providing an electric push rod 4, the electric push rod 4 is controlled to extend and retract to drive the cutting knife 504 to move up and down to cut the cardboard. At the same time, the inclined cutting knife 504 can easily apply cutting force to the cardboard, thereby improving the efficiency of cardboard cutting.

[0024] The top end of the fixing rod 501 passes through the fixing plate 5 and is fixedly installed with a limited top plate 502. A buffer spring 505 is provided on the surface of the fixing rod 501 between the fixing plate 5 and the knife holder 503. Due to the buffer spring 505, when the cutting knife 504 contacts the cardboard for cutting, the cardboard will lift up the cutting knife 504, compressing and deforming the buffer spring 505, thereby buffering the cutting knife 504 from squeezing the cutting cardboard, thereby preventing the cutting knife 504 from directly colliding with the cardboard and causing damage to the cutting knife 504.

[0025] A rectangular groove 6 is provided on one side of the top of the cutting platform 2 away from the adjusting frame 3. Due to the rectangular groove 6, when a cardboard is placed inside the rectangular groove 6 and pushed, it is ensured that the cardboard will not slide off from both sides of the rectangular groove 6;

[0026] A clamping frame 7 is provided on one side of the cutting platform 2 located at the top of the rectangular groove 6 close to the adjusting frame 3, and clamping rods 703 are fixedly installed at both ends of the bottom of the clamping frame 7, and the bottom ends of two groups of clamping rods 703 on the same side of the bottom of the clamping frame 7 pass through the cutting platform 2 and are fixedly installed with a limiting bottom plate 704, and a connecting plate 706 is fixedly installed between the two groups of limiting bottom plates 704. A clamping spring 705 is provided on the surface of the clamping rod 703 located between the cutting platform 2 and the limiting bottom plate 704. By providing the clamping spring 705, the clamping frame 7 is pressed toward the cutting platform 2 under the rebound action of the clamping spring 705, ensuring that the clamping roller 702 can be pressed against the top of the cardboard.

[0027] Three sets of mounting shafts 701 are fixedly installed at equal intervals inside the top of the pressing frame 7, and a pressing roller 702 is rollingly installed on the surface of the mounting shaft 701. Due to the presence of the pressing roller 702, the cardboard is pushed to move at the bottom of the pressing roller 702, and the pressing roller 702 rolls under the action of friction, thereby reducing the friction between the cardboard and the pressing frame 7, making it easier to push the cardboard toward the cutting knife 504.

[0028] The working principle of the utility model is:

[0029] The adjusting knob 302 is rotated to control the movable top plate 304 to move on the top of the adjusting frame 3. The movable top plate 304 is moved to a suitable position on the top of the adjusting frame 3 according to the length of the cutting edge of the cardboard belt. The pressing frame 7 is lifted up to put the cardboard into the rectangular groove 6, and the cardboard is pushed to the bottom of the pressing frame 7. The pressing frame 7 is released and the pressing frame 7 is pressed toward the cardboard under the rebound action of the pressing spring 705, so that the pressing roller 702 can be pressed on the top of the cardboard, and the cardboard is pushed to move on the top of the pressing roller 702 until the cardboard passes over the cutting knife 504 and is close to the movable top plate 304. The electric push rod 4 is controlled to retract, so that the cutting knife 504 moves down close to the cutting platform 2 to cut the cardboard.

[0030] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0031] The above describes in detail the preferred implementation of this patent, but this patent is not limited to the above implementation. Various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of this patent.
