Description

Technical Field

[0001] The utility model relates to the technical field of packaging material processing, in particular to a flattening and cutting device for a carton film laminating machine. Background Technique

[0002] Flattening and cutting machines are mechanical devices widely used in industry and manufacturing. Their main function is to flatten or deform materials or workpieces through the action of pressure and force. Flattening and cutting machines play an important role in many industries. Their efficacy lies in improving work efficiency, improving product quality, and enhancing production capacity.

[0003] For example, a flattening and cutting device for a carton film laminating machine with the authorization announcement number of "CN213891448U" is provided. By setting a screw rod and a threaded sleeve at one end of the connecting rod, rotating the threaded sleeve can drive the connecting rod to move in its axial direction, thereby driving the cutter wheel to move, realizing the position adjustment of the cutter wheel. The "T"-shaped block on the connecting cylinder can slide along the "T"-shaped groove on the slide rail and be fixed by bolts, which is convenient for adjusting the position of the cutter wheel in the vertical direction. However, for this flattening and cutting device of the carton film laminating machine, there is no limit on the cutting table, resulting in the inability to accurately cut the carton into a straight line during cutting, so that the cut carton has deviations and does not meet the work requirements, thereby reducing the production quality. At the same time, for the flattening and cutting device of the carton film laminating machine, through the cooperation of the "T"-shaped block and the "T"-shaped groove and the locking of the threaded rod, its adjustment requires rotating the threaded rod multiple times to complete, and this process will consume a lot of time for the staff, thereby reducing work efficiency. Content of the Utility Model

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

The middle of the upper end of the bottom plate is fixedly connected with the machine body. Adjusting mechanisms are symmetrically arranged at the upper end of the bottom plate. Hydraulic cylinders are fixedly connected to the left protrusions of the bottom plate. A limiting mechanism is arranged at the upper end of the protrusions of the bottom plate. A bent plate is arranged above the bottom plate. The protrusions at the lower end of the bent plate are rotatably connected with cutter wheels through bearings.

The lower end of the bolt is rotatably connected with a protective sleeve through a bearing.

[0009] Preferably, the lower end of the first outer shell is fixedly connected to the bottom plate, and the end of the sliding frame is fixedly connected to the straight plate.

[0010] Preferably, the adjusting mechanism includes a second outer shell. A third motor is fixedly connected to the right end of the outer wall of the second outer shell. The output shaft of the third motor is rotatably connected with the second outer shell through a bearing. The output shaft of the third motor is fixedly connected with a threaded rod. The threaded rod is threadedly connected with a first slider. The other end of the threaded rod is rotatably connected with a vertical plate through a bearing. The lower end of the first slider is slidably connected with the second outer shell. The upper end of the first slider is movably connected with a first connecting rod through a pin shaft. The upper end of the first connecting rod is movably connected with a cross plate through a pin shaft.

Because the straight plate is attached to the processing plate, when the inner sides of the outer walls of the two straight plates are attached to the carton, the carton on the processing plate can be limited. By limiting the two sides of the carton with the straight plate, the carton can only move in a straight line, and it can be accurately cut, reducing the situation that the cut carton has deviations and does not meet the work requirements, and improving the production quality.

The cross plate moves up and down to drive the bent plate to move up and down, and the bent plate moves up and down to drive the cutter wheel to move up and down to realize the adjustment of the cutter wheel. By adjusting it through the adjusting mechanism, it is not necessary to rotate multiple threaded rods for adjustment and locking, reducing the time consumed for adjustment, thereby improving the work efficiency.

[0031] Working principle:

[0032] When it is necessary to perform film coating on the carton and flatten and cut it.

[0033] Preparation work:

[0034] First, the staff places the cardboard box into the machine body 6. The machine body 6 has the same working principle as the machine body in the flattening and cutting device of a cardboard box film laminating machine with the authorized announcement number of "CN213891448U", and will not be elaborated here. (Such as Figure 1 ) After the machine body 6 flattens and laminates the cardboard box, it is transported to the processing plate 2.

[0035] Limiting process of the cardboard box:

[0036] Start the second motor 402. The output shaft of the second motor 402 rotates to drive the turntable 403 to rotate. (Such as Figure 4 ) The rotation of the turntable 403 drives the first cylinder 404 to rotate. The rotation of the cylinder 404 slides along the vertical chute processed on the sliding frame 405, thereby driving the sliding frame 405 to move. Since the second cylinder 406 slides in the horizontal chute of the sliding frame 405 to limit the sliding frame 405, the sliding frame 405 moves left and right. The left and right movement of the sliding frame 405 drives the straight plate 10 to move. The sliding frames 405 of the two limiting mechanisms 4 move inward, thereby driving the two straight plates 10 to move inward. (Such as Figure 1 ) Since the straight plate 10 is attached to the processing plate 2, when the inner sides of the outer walls of the two straight plates 10 are attached to the cardboard box, the cardboard box on the processing plate 2 can be limited. Stop the second motor 402. The second motor 402 is a servo motor with a self-locking function. When greater force is required, the bolt 407 can be rotated to make the bolt 407 move downward, driving the protective sleeve 408 to move downward and pressing tightly against the sliding frame 405 to achieve stronger self-locking. The protective sleeve 408 plays a role in protecting the sliding frame 405 to limit the cardboard box, ensuring the linear movement of the cardboard box, reducing the possibility of deviation, and ensuring product quality.

[0037] Adjustment process of the cutter wheel position:

[0038] Start the third motor 502. (Such as Figure 6 ) The output shaft of the third motor 502 rotates to drive the threaded rod 504 to rotate. The rotation of the threaded rod 504 drives the first slider 503 to slide left and right along the slideway processed on the second housing 501. The sliding of the first slider 503 drives the first connecting rod 505 to move. The movement of the first connecting rod 505 drives the cross plate 509 to move up and down. The up and down movement of the cross plate 509 drives the second slider 507 to slide left and right along the chute processed at the lower end of the cross plate 509. The sliding of the second slider 507 drives the second connecting rod 506 to move. The first connecting rod 505 and the second connecting rod 506 move around a center to ensure the stable up and down movement of the cross plate 509. The up and down movement of the cross plate 509 drives the bending plate 7 to move up and down. The up and down movement of the bending plate 7 drives the cutter wheel 9 to move up and down. (Such as Figure 1), at this time, the height of the cross plate 509 is the lowest. Control the output shaft of the third motor 502 to rotate, so that the cross plate 509 moves upward to a suitable position, then turn off the third motor 502 to make the cross plate 509 stop at this height. Then start the hydraulic cylinder 8. The telescopic movement of the output end of the hydraulic cylinder 8 drives the adjustment mechanism 5 to move, thereby driving the cutter wheel 9 to move. When the cutter wheel 9 moves to a suitable position, turn off the hydraulic cylinder 8 to make the cutter wheel 9 stop at this position, so as to realize the position adjustment of the cutter wheel 9. There is no need to turn multiple bolts to adjust the position of the cutter wheel 9. The quick adjustment is realized through the hydraulic cylinder 8 and the adjustment mechanism 5, saving a lot of time and improving work efficiency.

[0039] Cutting process of the cardboard box:

[0040] Start the first motor 3. The rotation of the output shaft of the first motor 3 drives the cutter wheel 9 to rotate. (Such as Figure 1 ), the cutter wheel 9 rotates. The rotation of the cutter wheel 9 can cut the cardboard box. The staff drags the cardboard box to make the cardboard box pass under the cutter wheel 9, so that the cutter wheel 9 completes the cutting. Repeat the above operation for continuous cutting. After completion, turn off the first motor 3 to realize the cutting of the cardboard box.
