Detailed Implementation

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0027] like Figure 1-8As shown, an automated bag making and filling machine includes: a film feeding area for conveying the film in a U-shape; a bag forming area for dividing the film to form continuously connected bags; a bag cutting area for cutting the continuously connected bags into individual bags and moving them to the filling area by a bag transfer assembly; a filling area for filling bags by fixing the bags with a rotary disc, and a bag opening assembly is provided in the area in front of the filling head 1; and a sealing area for sealing the filled bags by transferring them to the ultrasonic sealing assembly 2 via the rotary disc.

[0028] The film feeding area includes a triangular ring with its pointed corners facing downwards. The film surface contacts the pointed corners and is gathered by a gathering plate located behind the triangular ring, forming a U-shaped body without gaps. When the film passes through the triangular ring, the gathering plate gathers the two sides of the film, and under the traction of the triangular ring, it forms a U-shaped body and is then clamped by the feeding roller.

[0029] A tension adjustment assembly is provided at the tail end of the film feeding area. The tension adjustment assembly includes a fixed frame 5, which is equipped with a pinch roller for the film to pass through. A movable tension frame 4 is provided on the fixed frame 5. The tension frame 4 is adjusted by a cylinder. The film passes through the tension frame 4 before being fed into the pinch roller. If the film is loose, the angle of the tension frame 4 can be adjusted to tighten the film. Conversely, when the film is too tight, the tension frame 4 is loosened to keep the film under a certain tension.

[0030] The bag-making area includes a bag-making assembly, which includes vertical sealing blocks 7. Two sets of vertical sealing blocks 7 are provided and are movably disposed within the second fixing frame 6. The two sets of vertical sealing blocks 7 are moved away from or closer together by the rotation of the actuating plate 8. The two ends of the actuating plate 8 are respectively connected to the corresponding vertical sealing blocks 7 through connectors. A sliding rail is provided at the bottom of the second fixing frame 6. When the film passes through the bag-making assembly, the vertical sealing blocks 7 on both sides are driven by the actuating plate 8 to apply pressure to the film and form a pocket area. Different sizes can be adjusted by moving the second fixing frame 6.

[0031] A horizontal sealing block is provided at the inlet of the bag-making assembly. The horizontal sealing block is set on the lifting frame and applies pressure to seal the bottom of the film.

[0032] A diamond-shaped tearing mechanism is provided at the outlet of the bag-making assembly. The diamond-shaped tearing mechanism opens into the side wall of the formed bag body that passes through. Two sets of opposite bag-pulling wheels 10 are provided behind the diamond-shaped tearing mechanism. Guide rails 9 for the bag body to pass through are provided at the upper and lower ends between the two sets of bag-pulling wheels 10. When continuous bags pass through, the diamond-shaped tearing mechanism can punch the connection between the two bags to form an easy-tear opening.

[0033] The bag cutting area is equipped with a cutting assembly 12 for cutting the bag body. The cutting assembly 12 includes a scissor-type cutter consisting of at least two sets of cutting blades. Both sets of cutting blades are sleeved on the drive shaft of gear 2 16 through a sleeve. One cutting blade is rotatably connected via a bearing, and the other cutting blade rotates with the sleeve on the drive shaft of gear 2 16. The side of the rotatably connected cutting blade is connected to a fork. The groove of the fork is engaged with the shaft at one end of the connecting block 14, and the other end of the connecting block 14 is engaged with the gear. On the drive shaft of gear 15, gear 15 and gear 2 16 simultaneously mesh with the drive gear. The cutting blade can be adjusted laterally through the sleeve. When the drive gear rotates, gear 15 and gear 2 16 rotate in the same direction. The drive shaft on gear 15 drives the paddle block 13 to rotate counterclockwise, and the cutting blade on the drive shaft of gear 2 16 rotates clockwise. In this way, the two cutting blades form a cutting action to cut and separate the continuous bag body. The bag clamp 11 before cutting will clamp the bag body in advance.

[0034] The bag transfer assembly is located above the cutting assembly 12. It includes a bag transfer clamp 11, which is provided in two parallel sets. The bag transfer clamp 11 is set on the transverse transfer module, so that the two sets of bag transfer clamps 11 can move away from each other or close to each other. The transverse transfer module is set on the longitudinal transfer module. The cut bags are moved to the clamps of the rotating disk and fixed by the bag transfer clamp 11.

[0035] The bag opening assembly includes a transplanting arm 17, which is mounted on the rotating shaft of the rotating disk with or without following it. A bag-supporting claw 18 is provided at the end of the transplanting arm 17. The bag-supporting claw 18 keeps the bag open and rotates with the rotating disk. A fixed bag opening arm 19 is provided on the side of the rotating disk. The bag opening arm 19 is used to suck open the two sides of the bag and open it. The bag opening arm 19 is used to suck open the two sides of the bag and open it. The bag-supporting claw 18 is used to keep the bag open until the filling position, and then return to the starting position to repeat the operation.

[0036] A duster wheel 20 is provided between the ultrasonic sealing assembly 2 and the filling head 1. A cover is provided above the duster wheel 20, and a negative pressure pipe is opened on the cover. A shaping assembly 3 is provided in the area behind the ultrasonic sealing assembly 2 to remove the residue at the opening and prevent the residue from being sealed at the same time. The shaping can trim the sealing area and keep the sealing neat and flat.

[0037] Operating principle: The film roll passes through multiple rollers sequentially from the film roll holder, guided by triangular rings and gathered into a U-shape by a gathering plate. After tension adjustment by tensioner 4, it passes through the gap between the feeding rollers. Passing through the horizontal sealing block area, the bottom of the film is horizontally sealed. Then, at the bag-making assembly, two vertical sealing actions are performed to complete the sealing of the left, right, and bottom edges, forming the bag. Here, the left and right sealing spacing can be adjusted according to different bag sizes. The film is then conveyed forward again, and when passing through the diamond tearing mechanism, an easy-tear opening is made at the connection between adjacent bags. After completion, it enters the bag-cutting area, where the continuous bag is cut into individual bags by the cutting assembly 12. The cutting assembly 12 can also... The spacing is adjusted according to the specifications. Simply move the cutting scissors on the left side according to the scale. After cutting, the bag is clamped by the bag transfer clamp 11 and sent to the bag clamping position on the rotating plate. The rotating plate rotates and moves the bag to the bag opening arm 19, opening the bag. After opening, the bag support claw 18 enters the opening and keeps the bag opening open. The rotating plate rotates again, and the bag support claw 18 moves to the bottom of the filling head 1. The bag support claw 18 returns to the starting position, and the filling head 1 begins filling. After filling, the rotating plate moves the bag to the bag dusting wheel 20, dusts up the residue at the opening and sucks it away by negative pressure, then moves it to the ultrasonic sealing assembly 2 for sealing, and finally moves it to the shaping assembly 3 for finishing.

[0038] It should be noted that in this article, relational terms such as first and second are used only to distinguish one entity from another, and do not necessarily require or imply any such actual relationship or order between these entities.

[0039] The examples above are merely illustrative of the present invention and do not constitute a limitation on the scope of protection of the present invention. All designs that are the same as or similar to the present invention are within the scope of protection of the present invention.
