Description

Technical Field

[0001] The utility model belongs to the technical field of sealing, and in particular relates to a sealing mechanism of an automatic packaging machine for vegetable fat powder. Background Art

[0002] There are many types of non-dairy creamer packaging bags, which are mainly suitable for enterprises or stores of different sizes. In order to expand sales channels, enterprises are provided with a variety of packaging bags such as self-supporting bags, handbags, zipper bags, four-side sealing bags, three-side sealing bags, paper bags and other composite bags. These packaging bags can be sealed by continuous sealing machines, which have good sealing effects and fast speeds to meet production needs. However, existing continuous sealing machines require the cooperation of employees to operate, mainly because the bag opening needs to be flattened before sealing to ensure the flatness and aesthetics of the bag opening after sealing. If the bag opening is folded when sealing, the folded area of the seal is prone to leakage. Utility Model Content

[0017] Embodiment 1

[0018] As Figures 1 to 3As shown in the figure; a sealing mechanism for a creamer automatic packaging machine, which includes a belt conveyor 1, a continuous sealing machine 2, a fixed frame 3, a pressing belt conveyor 4 and a bag mouth finishing device 5. The belt conveyor 1, the continuous sealing machine 2, the pressing belt conveyor 4 and the bag mouth finishing device 5 are all installed on the fixed frame 3. The two pressing belt conveyors 4 are symmetrically arranged and located between the continuous sealing machine 2 and the bag mouth finishing device 5. The bag mouth finishing device 5 includes an extrusion cylinder 51, an extrusion plate 52 and a whole bag mouth device 54. The two extrusion cylinders 51 are symmetrically arranged and installed on the fixed frame 3. The two extrusion plates 52 are symmetrically arranged and connected to the piston rods of the corresponding extrusion cylinders 51. The whole bag mouth device 54 is arranged above the two extrusion plates 52. The whole bag mouth device 54 includes a displacement motor 55, a displacement lead screw 56, a displacement frame 57, a lifting cylinder 58, a lifting plate 510 and a finger cylinder 511. The displacement lead screw 56 is movably connected to the fixed frame 3 and one end is connected to the displacement motor 55. The displacement frame 57 is slidably connected to the fixed frame 3. The lifting cylinder 58 is connected to the displacement frame 57 and the piston rod is connected to the lifting plate 510. A number of avoidance openings 59 are arranged in a "one" shape on the lifting plate 510. A finger cylinder 511 is connected to the lifting plate 510 on one side of the avoidance opening 59. Two L-shaped traction whole bag mouth plates 512 are connected to the piston rod of the finger cylinder 511. A positioning cylinder 53 is connected to the extrusion plate 52. A positioning plate is connected to the piston of the positioning cylinder 53, and a contact sensor is arranged on the positioning plate. A CCD high-definition camera is arranged on the fixed frame 3 on one side of the positioning cylinder 53. The end of the L-shaped traction whole bag mouth plate 512 away from the finger cylinder 511 is flat.

[0019] The packed bag is conveyed between the two squeezing plates 52 by the belt conveyor 1, and contacts the positioning plate closest to the compacting belt conveyor 4 and is sensed by the contact sensor. Then the positioning cylinder 53 of the adjacent position drives the positioning plate to extend to block and position the next bag, and multiple bags are positioned in this cycle. After the bag is positioned, the two squeezing cylinders 51 respectively drive the two squeezing plates 52 to squeeze the bag, so that the space in the bag becomes narrower. At this time, the material in the bag will be squeezed toward the bag opening to stretch the bag opening, so as to prevent the bag opening from closing and being unable to be leveled. The lifting cylinder 58 drives the lifting plate 510 to descend, so that the two L-shaped traction whole-mouth plates 512 on the finger cylinder 511 are inserted into the bag opening of the bag. After confirming whether the L-shaped traction whole-mouth plate 512 is inserted into the bag through the CCD high-definition camera, the finger cylinder 511 drives the two L-shaped traction whole-mouth plates 512 away, so that the bag opening is stretched and stretched. The bag is then clamped by the two compression belt conveyors 4 and the displacement screw 56 is driven to rotate, so that the displacement frame 57 moves and conveys the bag leveled by the finger cylinder 511 to between the two compression belt conveyors 4 for clamping and conveying. The bag is clamped and conveyed to the continuous sealing machine 2 for sealing. After the bag is clamped by the two compression belt conveyors 4, the finger cylinder 511 controls the L-shaped traction whole-mouth plate 512 to move closer, and then the lifting cylinder 58 drives the lifting plate 510 to rise again, so that the L-shaped traction whole-mouth plate 512 moves out of the bag, and then the displacement screw 56 drives the bag-opening device 54 to reset, and the bag is leveled in this cycle.
