A cutting device for a packaging machine

Abstract

This utility model discloses a cutting device for a packaging machine. After the workpiece to be cut is placed into the feed trough of the processing table, the drive unit is activated, and its output end drives the drive shaft to rotate stably. The drive shaft drives the turntable to rotate, and through the connecting rod, drives the mounting plate to swing back and forth around the rotating rod, causing the cutter to cut back and forth. On the other hand, the half gear on the drive shaft intermittently meshes with the driven gear on the transmission shaft, causing the turntable to rotate through the transmission shaft and the turntable. The guide rod on the turntable pushes the guide plate to move intermittently in a linear motion. The guide plate drives the push block to slide intermittently through the push rod, gradually pushing the workpiece towards the cutter. When the workpiece reaches the appropriate position, the cutter cuts it, and the cut workpiece is discharged from the outlet and discharged through the guide plate. This device realizes automatic, precise, and orderly cutting of workpieces, improving production efficiency and product quality.

Description

Technical Field

[0001] This utility model relates to a cutting device, specifically a cutting device for a packaging machine. Background Technology

[0002] In the packaging manufacturing industry, the cutting process is a key step in ensuring uniform product specifications and aesthetically pleasing packaging. Its efficiency and precision directly affect the overall production efficiency and product quality.

[0003] Traditional packaging machines rely heavily on manual cutting, which is not only labor-intensive and costly, but also prone to errors, making it difficult to guarantee consistent size and position for each cut. This leads to higher defect rates and fails to meet the demands of large-scale, high-quality packaging production. While some packaging machines have begun using automated cutting devices, existing automated devices suffer from complex structures, susceptibility to jamming, and the tendency for cut materials to pile up and become disorganized, requiring additional manual intervention and reducing production efficiency. Therefore, a cutting device for packaging machines needs to be designed to address this problem. Utility Model Content

[0015] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0016] Please see Figures 1-3 As an embodiment of this utility model, a cutting device for a packaging machine includes a processing table 1, on which a feeding groove 2 is provided, and a pusher block 24 is slidably installed in the feeding groove 2. Vertical plates 4 are symmetrically installed on the processing table 1, and a rotating rod 5 is rotatably installed on the vertical plates 4. An mounting plate 6 is installed on the rotating rod 5, and a cutter 7 is installed on one side of the mounting plate 6. An outlet 26 is provided at one end of the feeding groove 2 near the cutter 7. A limiting groove is provided on the processing table 1, and a limiting block is slidably installed in the limiting groove. A fixed... A fixed rod 25 is attached to a guide plate 20 at one end away from the limiting block. A push rod 23 is installed on one side of the guide plate 20. The push rod 23 is connected to a push block 24 at one end away from the guide plate 20. A drive assembly is installed on the processing table 1. A transmission assembly and an intermittent push assembly are installed on the drive assembly. The transmission assembly is connected to a mounting plate 6 at one end away from the drive assembly. The intermittent push assembly is connected to the guide plate 20 at one end away from the drive assembly. A flow guide plate 3 is installed on the processing table 1 and is located on one side of the discharge port 26.

[0017] In this embodiment, when the workpiece 8 to be cut enters the feed trough 2, the drive assembly on the processing table 1 starts to work. The drive assembly provides power to both the transmission assembly and the intermittent push assembly. On one hand, the transmission assembly operates under the drive of the drive assembly. Since the end of the transmission assembly away from the drive assembly is connected to the mounting plate 6, and the mounting plate 6 is rotatably mounted on the vertical plate 4 via the rotating rod 5 and has a cutter 7 mounted on one side, the transmission assembly transmits power to the mounting plate 6, causing the mounting plate 6 to oscillate back and forth around the rotating rod 5, thereby driving the cutter 7 to perform reciprocating cutting motion. On the other hand, the intermittent push assembly works under the drive of the drive assembly. The end of the intermittent push assembly away from the drive assembly is connected to the guide plate 20. The guide plate 20 is connected to the limit block sliding in the limit groove via the fixed rod 25. Under the action of the intermittent push assembly, the guide plate 20 will perform intermittent linear motion on the processing table 1. A push rod 23 is installed on one side of the guide plate 20. The end of the push rod 23 away from the guide plate 20 is connected to the push block 24 in the feed trough 2. Therefore, the intermittent linear motion of the guide plate 20 will cause the push block 24 to slide intermittently in the feed trough 2 through the push rod 23. The push block 24 pushes the workpiece 8 in the feed trough 2 to move gradually closer to the cutter 7. When the workpiece 8 moves to the appropriate position, the cutter 7 performs the cutting action. After the cutting is completed, the push block 24 continues to intermittently push the remaining workpiece 8. The cut workpiece 8 is discharged from the outlet 26 at the end of the feed trough 2 near the cutter 7 and is discharged through the guide plate 3 set on one side of the outlet 26, completing the entire cutting process.

[0018] As an embodiment of the present invention, the driving assembly includes a driving component 14, which is mounted on the processing table 1. A driving shaft 12 is mounted on the output end of the driving component 14. The driving shaft 12 passes through the processing table 1 and is rotatably connected to the processing table 1.

[0019] In this embodiment, the drive unit 14 is mounted on the processing table 1. When the drive unit 14 is started, its output end drives the drive shaft 12 to rotate. The drive shaft 12 passes through the processing table 1 and is rotatably connected to the processing table 1, thereby stably outputting power and providing rotational power for the subsequent transmission components and intermittent push components.

[0020] Furthermore, the driving component 14 can be a stepper motor or a servo motor, etc., which will not be described in detail here.

[0021] As an embodiment of the present invention, the transmission assembly includes a turntable 9, which is connected to the end of the drive shaft 12 away from the drive member 14. A connecting rod 11 is provided on one side of the turntable 9, and the two ends of the connecting rod 11 are rotatably connected to the mounting plate 6 and the turntable 9 respectively through pivot pins 10.

[0022] In this embodiment, the turntable 9 is connected to the end of the drive shaft 12 away from the drive member 14. The rotation of the drive shaft 12 drives the turntable 9 to rotate. The two ends of the connecting rod 11 on one side of the turntable 9 are rotatably connected to the mounting plate 6 and the turntable 9 respectively through the pivot pin 10. When the turntable 9 rotates, the connecting rod 11 will make a circular motion with the turntable 9, and at the same time drive the mounting plate 6 to swing back and forth around the rotating rod 5, thereby causing the cutter 7 on the mounting plate 6 to make a reciprocating cutting motion.

[0023] As an embodiment of this utility model, the intermittent pushing component includes a mounting cavity. The mounting cavity is provided on the processing table 1. The drive shaft 12 passes through the mounting cavity, and a transmission shaft 17 is rotatably mounted on the processing table 1. One end of the transmission shaft 17 extends into the mounting cavity and is connected to a driven gear 15. A half gear 13 is mounted on the drive shaft 12. The half gear 13 and the driven gear 15 intermittently mesh. A rotating shaft 16 is mounted on the processing table 1. A disk 19 is connected to the end of the rotating shaft 16 away from the processing table 1. A guide rod 22 is eccentrically mounted on the disk 19. A guide groove 21 is provided on the guide plate 20. The end of the guide rod 22 away from the disk 19 extends into the guide groove 21. A connecting unit 18 is mounted on the transmission shaft 17. The end of the connecting unit 18 away from the transmission shaft 17 is connected to the rotating shaft 16.

[0024] In this embodiment, when the drive shaft 12 rotates, the half gear 13 intermittently meshes with the driven gear 15, causing the transmission shaft 17 to rotate intermittently. The transmission shaft 17 drives the rotating shaft 16 to rotate through the connecting unit 18, and the rotating shaft 16 drives the disc 19 to rotate. The guide rod 22 on the disc 19 slides in the guide groove 21, thereby pushing the guide plate 20 to perform intermittent linear motion. The guide plate 20 drives the push block 24 to slide in the feed groove 2 via the push rod 23, realizing intermittent feeding of materials. This intermittently pushes one end of the workpiece 8 to one side of the cutter 7, allowing the material to enter the cutting area according to the set rhythm, ensuring the accuracy and stability of the cutting, and improving the efficiency of the cutting by coordinating the orderly cutting.

[0025] Furthermore, the connecting unit 18 can be a gear set or a pulley set, etc., which will not be described in detail here.

[0026] The working principle of this utility model is as follows: After the workpiece 8 to be cut is placed into the feed trough 2 of the processing table 1, the drive component 14 installed on the processing table 1 is activated. Its output end drives the drive shaft 12 to rotate. The drive shaft 12 passes through the processing table 1 and outputs rotational power stably. On one hand, the drive shaft 12 drives the turntable 9 connected to it to rotate. The two ends of the connecting rod 11 on one side of the turntable 9 are connected to the mounting plate 6 and the turntable 9 respectively through the pivot pin 10. The connecting rod 11 moves in a circular motion with the turntable 9, causing the mounting plate 6 to swing back and forth around the rotating rod 5, so that the cutter 7 on the mounting plate 6 performs reciprocating cutting. On the other hand, the half gear 13 on the drive shaft 12 intermittently meshes with the driven gear 15 at one end of the transmission shaft 17, causing the transmission shaft 17 to rotate intermittently. The transmission shaft 17 drives the rotating shaft 16 to rotate through the connecting unit 18. The rotating shaft 16 causes the disc 19 to rotate. The guide rod 22 eccentrically installed on the disc 19 slides in the guide groove 21 of the guide plate 20, pushing the guide plate 20 to perform intermittent linear motion. The guide plate 20 drives the pusher block 24 in the feed trough 2 to slide intermittently via the pusher rod 23, gradually pushing the workpiece 8 toward the cutter 7. When the workpiece 8 reaches the appropriate position, the cutter 7 falls to cut. After cutting, the pusher block 24 continues to intermittently push the remaining workpiece 8, and the cut workpiece 8 is discharged from the discharge port 26 and discharged through the guide plate 3, completing the entire cutting process.
