[0022] Figures 1-4 The present invention relates to a lifting and cutting mechanism for carton production, comprising a base 10, a lifting component 20, a cutting component 30, and a limiting component 40.

[0023] In this embodiment:

[0024] The lifting assembly 20 includes a fixed base 21, a first connecting rod 22, a push rod 23, a second connecting rod 24, a top rod 25, and a push cylinder 26.

[0025] A fixed base 21 is mounted on a base 10. A first connecting rod 22 is rotatably mounted on the fixed base 21, and a second connecting rod 24 is rotatably mounted on the first connecting rod 22. One end of a push rod 23 is located at the connection between the first connecting rod 22 and the second connecting rod 24, and the other end is located at the end of a push cylinder 26. The push cylinder 26 is horizontally mounted on the base 10. A push rod 25 is vertically mounted on the second connecting rod 24, with its top located in the positioning groove 341 of the feeding plate 34. The axial direction of the push rod 23 is perpendicular to the axial direction of the push rod 25. The push cylinder 26 drives the push rod forward, causing the first connecting rod 22 and the second connecting rod 24 to rotate. When the bottom of the push rod 25 contacts the feeding plate 34, the top of the push rod 25 passes through the positioning groove 341 and extends out. At this time, the extension lines of the push rod 25, the first connecting rod 22, and the second connecting rod 24 are all straight lines, and the cardboard on the feeding plate 34 is pushed out into place.

[0026] The cutting assembly 30 includes a cutting cylinder 31, a blade 32, a mounting block 33, a feeding plate 34, and an adjusting column 35. The cutting cylinder 31 is mounted on the feeding plate 34, the mounting block 33 is located at the end of the cutting cylinder 31, the blade 32 is vertically mounted on the mounting block 33, cardboard is placed on the feeding plate 34, and the feeding plate 34 is provided with a positioning groove 341 and a positioning hole. The adjusting column 35 is vertically mounted on the base 10 and extends out from the positioning hole. In this embodiment, the extending direction of the cutting cylinder 31 is perpendicular to the extending direction of the pushing cylinder 26.

[0027] The limiting assembly 40 includes two guide posts 41, a fixing plate 42, a limiting cylinder 43, a limiting block 44, and two guide sleeves 45. The limiting cylinder 43 is mounted on the base 10, and the limiting block 44 is located at the end of the limiting cylinder 43 and on one side of the feeding plate 34. The limiting block 44 is used to limit one end of the cardboard after the push rod 25 has been pushed out. The two guide posts 41 are vertically mounted on the base 10, and the two guide sleeves 45 are respectively mounted on the two guide posts 41. The fixing plate 42 is used to connect the two guide sleeves 45, and the limiting block 44 is mounted on the fixing plate 42.

[0028] The adjusting assembly 50 includes a pressure block 51, a trapezoidal screw 52, ​​a trapezoidal nut 53, and an adjusting handwheel 54. The base 10 is provided with a guide rail 11, and the pressure block 51 is slidably mounted on the guide rail 11. The extension direction of the guide rail 11 is parallel to the axial direction of the pusher cylinder 26. The fixed seat 21 and the guide post 41 are both provided on the pressure block 51. The trapezoidal screw 52 is horizontally arranged on one side of the pressure block 51 and abuts against one end of the pressure block 51. The adjusting handwheel 54 is located at the head end of the trapezoidal screw 52, ​​and the trapezoidal nut 53 is located on the trapezoidal screw 52. Rotating the adjusting handwheel 54 causes the trapezoidal nut 53 to move along the axial direction of the trapezoidal screw 52 until it abuts against one end of the guide rail 11.

[0029] In this application, the lifting component 20, the cutting component 30, and the limiting component 40 are all disposed on the base 10, and the lifting component 20 is disposed between the cutting component 30 and the limiting component 40.

[0030] In use, the cardboard is first placed on the feeding plate 34. The pushing cylinder 26 drives the pushing rod 23 to move forward, which in turn drives the push rod 25 to move upward through the first connecting rod 22 and the second connecting rod 24 until the bottom of the push rod 25 contacts the feeding plate 34, thus pushing the cardboard into place. Then, the limiting cylinder 43 drives the limiting block 44 to move upward, so that the limiting block 44 contacts one end of the cardboard. The cutting cylinder 31 drives the mounting block 33 and the blade 32 to move forward, so that the blade 32 contacts the other end of the cardboard, thus confining the cardboard between the positioning block and the blade 32. Finally, the cutting cylinder 31 drives the mounting block 33 and the blade 32 to continue moving forward, thus completing the cutting of the cardboard.

[0031] This application uses a lifting component 20 to lift the cardboard for cutting, thereby protecting the bottom of the cardboard from damage, ensuring the production quality of the carton, and meeting customer needs. The overall structure of this application is compact, occupies little space, and is easy to transport.

This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
