Detailed Description
The ironing, cutting and cutting device for manufacturing the three-dimensional bag body of the present invention will be further described with reference to fig. 1 to 4.
The utility model provides a scald and connect, cut device for preparing three-dimensional bag body which characterized by: comprises a frame body 1, and a scalding and connecting mechanism 2 and a splitting mechanism 3 which are sequentially arranged on the frame body 1 along the conveying direction of a film 6 on the frame body 1. Scald and connect mechanism 2 including parallel arrangement's left side boiling hot knife tackle spare 21 and right side boiling hot knife tackle spare 22, the array orientation of left side boiling hot knife tackle spare 21 and right side boiling hot knife tackle spare 22 is perpendicular with film 6 direction of transfer, and the extending direction of left side boiling hot knife tackle spare 21 and right side boiling hot knife tackle spare 22 is the same with film 6 direction of transfer. The left ironing knife assembly 21 and the right ironing knife assembly 22 both comprise an upper ironing knife set 211, a lower ironing knife set 212 and a driving part 27 for driving the upper ironing knife set 211 and/or the lower ironing knife set 212 to move, and a film 6 ironing channel 23 is formed between the upper ironing knife set 211 and the lower ironing knife set 212. When the film 6 passes through the ironing channel 23, the upper ironing knife set 211 and the lower ironing knife set 212 can iron and weld the vertically overlapped film 6, that is, two ironing and welding edges for fixing the vertically overlapped film 6 are formed on the vertically overlapped film 6. The slitting mechanism 3 comprises a cutting knife 32, and the cutting knife 32 is positioned between the left ironing knife assembly 21 and the right ironing knife assembly 22.
Specifically, the driving component is a driving cylinder 27, and the upper ironing knife set 211 and the lower ironing knife set 212 are arranged on a piston rod corresponding to the driving cylinder 27 and driven by the driving cylinder 27 to move up and down. That is, in this embodiment, the upper ironing knife set 211 and the lower ironing knife set 212 are both connected with the driving cylinder 27, the cylinder body of the driving cylinder 27 is fixed on the frame body 1, and the piston rod is connected with the corresponding ironing knife set to drive the upper ironing knife set 211 and the lower ironing knife set 212 to move in opposite directions or in a back-to-back direction, so as to realize the ironing connection of the film 6 and the separation after the ironing connection.
The lower ironing knife group 212 is provided with partitions 25 at the peripheral positions, and openings 26 for the lower ironing knife group 212 to pass through are arranged among the partitions 25. Namely, the shelf body 1 is provided with the partition shelf 24, and the partition 25 is divided into a left partition and a right partition, and then is mounted on the partition shelf 24 through bolts and is positioned at the left and right sides of the lower ironing knife group 212. The film 6 is supported on the partition 25 during the transfer; after the ironing connection is completed, the partition plate 25 can also play a supporting role, so that the problem that the ironing connection part of the film 6 synchronously moves downwards along with the lower ironing knife group 212 is avoided, and the film 6 can be effectively separated from the lower ironing knife group 212.
The slitting mechanism 3 further comprises a cutter frame 31, the cutter 32 is mounted on the cutter frame 31 and mounted on the frame body 1 through the cutter frame 31, and the position of the cutter corresponds to that of two hot-sealing edges of the film 6, so that the film 6 is cut between the two hot-sealing edges.
The frame body 1 is also provided with a traction mechanism 4, and the traction mechanism consists of an upper traction roller and a lower traction roller. The traction mechanism 4 is positioned at the subsequent station of the splitting mechanism 3 to pull the film 6 to pass through the ironing mechanism 2 and the splitting mechanism 3.
The frame body 1 is further provided with a distance adjusting mechanism 5, the distance adjusting mechanism 5 is located on the subsequent process of the slitting mechanism 3, and the distance adjusting mechanism 5 comprises a guide roller set 53, a lifting plate 51 and a driving assembly 52. The lifting plate 51 is mounted on the frame body 1 through a lifting slide. Guide roller set 53 includes lift roller 531 and fixed roll 532, lift roller 531 and fixed roll 532 all have two to two lift rollers 531 are the V-arrangement structural distribution, and two fixed rolls 532 are the V-arrangement structural distribution, and two liang of parallel arrangement of lift roller 531 and two fixed rolls 532 to form two film passageway 54 that supply film 6 to pass through simultaneously between lift roller 531 and fixed roll 532, fixed roll 532 is installed on support body 1, lift roller 531 sets up on lifter plate 51. The driving assembly 52 is installed on the frame body 1 and connected with the lifting plate 51 to drive the lifting plate 51 to move up and down. The drive assembly 52 includes a servo motor 521 and a ball screw pair 522. The ball screw pair 522 is disposed between the lifting plate 51 and the frame body 1, and the servo motor 521 is connected with the ball screw pair 522 to drive the lifting plate 51 to move up and down. In this configuration, since the lifting roller 531 and the fixing roller 532 are inclined with respect to the transfer direction of the film 6, when the lifting roller 531 moves up and down with respect to the fixing roller 532, the film transferred in the corresponding film passage 54 moves in a direction perpendicular to the transfer direction of the film 6, thereby realizing adjustment of the distance between the two cut films.
When the film cutting machine is used specifically, the film 6 is divided into an upper layer and a lower layer, enters the frame body 1 and sequentially passes through the ironing connection mechanism 2, the cutting mechanism 3 and the distance adjusting mechanism 5.
When the film 6 passes through the ironing connection mechanism 2 and is in a conveying process, the corresponding driving cylinder 27 drives the upper ironing knife group 211 and the lower ironing knife group 212 to move in a back-to-back manner, so that the film 6 moves in the ironing connection channel 23, when the film 6 moves to a required position, the film 6 stops conveying, namely the traction mechanism 4 stops traction, the corresponding driving cylinders 27 in the left ironing knife assembly 21 and the right ironing knife assembly 22 drive the upper ironing knife group 211 and the lower ironing knife group 212 to move oppositely, two ironing connection sealing edges for fixing the upper film 6 and the lower film 6 are formed on the film 6, and the driving cylinders 27 drive the upper ironing knife group 211 and the lower ironing knife group 212 to reset;
the film 6 continues to move, and passes through the slitting mechanism 3, and in the moving process of the film 6, the cutter 32 cuts the film 6 between the two ironing and sealing edges to form a left film and a right film which are distributed leftwards and rightwards;
with the continuous movement of the film 6, the left film 6 and the right film 6 enter the two film channels 54 respectively, and the servo motor 521 drives the lifting roller 531 to lift according to actual needs so as to adjust the distance between the left film 6 and the right film 6 to adapt to the size needed by the three-dimensional bag body. In the three-dimensional bag body, the left film 6 and the right film 6 can become the left and right side surfaces of the three-dimensional bag body, so that the three-dimensional bag body can be conveniently prepared in the next process.
In the preparation process of the three-dimensional bag body, the device is integrated into a corresponding bag making machine, corresponding films are connected to upper film layers of the left film and the right film in a hot-pressing mode, corresponding films are connected to lower film layers of the left film and the right film in a hot-pressing mode to form the front side surface and the rear side surface of the three-dimensional bag body, and then two ends of the bag body are connected in a hot-pressing mode to form the three-dimensional bag body structure.
