Technical Field

[0001] The invention relates to the technical field of flour processing, in particular to an automatic flour packaging, conveying and packaging device. Background Art

[0002] During the flour processing, after measuring and bagging, the flour in the bag needs to be sewn at the bag mouth. The sewing is performed by a bag sewing machine. When sewing, the worker aligns the edges of the bag mouth and then straightens the bag mouth along the direction of the bag sewing line to make the edges of the bag mouth neat until the edge of the bag enters the working area of ​​the sewing equipment and is transported with the conveyor belt. In this way, when sewing, the bag sewing machine can sew the bag in a straight direction.

[0003] This operation method requires the worker to straighten the bag opening first, then convey it along the conveyor belt, and align the bag opening with the sewing position of the sewing equipment until the bag opening enters the sewing equipment.

In the initial state, the volute spring 27 drives the pivot 10 to rotate, so that the pivot 10 drives the straightening arms 26 to swing towards each other.

[0043] Working principle of the present invention:

[0044] After the metering and bagging equipment measures and conveys the flour to the packaging bag 31, the conveyor belt 1 is started and the packaging bag 31 containing the flour is conveyed to the bottom of the fixed seat 5, and the packaging bag 31 is located between the two strip plates 15. When the conveyor belt 1 conveys the packaging bag 31, the packaging bag 31 is supported by the anti-falling guardrail 2, that is, the packaging bag 31 leans against the anti-falling guardrail 2, so that the bag bottom 32 of the packaging bag 31 is supported by the conveyor belt 1, so that the entire packaging bag 31 is placed on the conveyor belt 1 in a standing state. When the packaging bag 31 is conveyed to the bottom of the fixed seat 5, the alignment cylinder 7 is started, the cylinder rod of the alignment cylinder 7 is extended, and the fixed block 14 is driven to move toward the packaging bag 31;

[0045] When the fixed block 14 moves, the strip plate 15 will be close to the packaging bag 31, and the sliding pin 21 will slide in the inclined hole 25 from the lower end of the inclined hole 25 in the inclined direction to the upper end of the inclined hole 25, so that the sliding pin 21 drives the driving rod 22 to move upward, and drives the strip plate 15 to move upward. In addition, when the strip plate 15 is close to the packaging bag 31, the external negative pressure device evacuates the inside of the connecting cavity 30 through the pipe interface 16, and the surface of the packaging bag 31 (or the two sides of the packaging bag 31 corresponding to the width direction of the conveyor belt 1) is adsorbed by the adsorption holes 29, so that the surface of the packaging bag 31 is attached to the surface of the strip plate 15. When the strip plate 15 moves upward, it can smooth the surface of the packaging bag 31 from bottom to top, so that the bag mouth 36 of the packaging bag 31 will gradually be in an upright state;

[0046] After the cylinder rod of the alignment cylinder 7 is extended to the right position, the upper edge of the strip plate 15 is flush with the upper edge of the bag opening 36 of the packaging bag 31, and the two sides of the bag opening 36 of the packaging bag 31 are pressed relatively by the two strip plates 15, and the bag opening 36 of the packaging bag 31 is closed and aligned with the stitching direction (reference Fig.13, the length direction of the stitching area 33 of the packaging bag 31 is consistent with the conveying direction of the conveyor belt 1, so the stitching direction can be said to be parallel to the conveying direction of the conveyor belt 1). At this time, although the bag opening 36 of the packaging bag 31 is closed, due to the process of being flattened by the strip plate 15, the surface of the bag opening 36 may be partially wrinkled and uneven. Therefore, the negative pressure device is started again, and the adsorption holes 29 of the strip plate 15 adsorb the surface of the packaging bag 31, and then the cylinder rod of the alignment cylinder 7 is shortened. During the short shortening process, the upper edge surface of the packaging bag 31 moves with the strip plate 15, thereby causing the bag opening 36 of the packaging bag 31 to be slightly opened. Then the negative pressure device stops starting. At this time, the adsorption state of the adsorption holes 29 on the surface of the packaging bag 31 disappears, and the bag opening 36 of the packaging bag 31 is slightly open.

[0047] Then, the driving cylinder 8 is started, the cylinder rod of the driving cylinder 8 is extended, and the sliding seat 28 is driven to move downward, so that the two straightening arms 26 can be inserted into the bag opening 36 of the packaging bag 31 which is slightly opened. As the sliding seat 28 continues to move downward, the gear 20 will begin to mesh with the teeth on the rack block 18. When meshing, the gear 20 will rotate, thereby causing the gear 20 to drive the straightening arms 26 to swing toward the radial outer side of the fixed seat 5, so that the two straightening arms 26 are respectively in a state of mutually expanding around the axial directions of the two pivots 10, and the pivot 10 contracts the spiral spring 27, and the spiral spring 27 begins to accumulate elastic potential energy. When the straightening arms 26 are mutually expanded, the ends of the straightening arms 26 will be expanded in the bag opening 36 of the packaging bag 31, so that the straightening arms 26 swing upward in the bag opening 36 of the packaging bag 31, thereby tightening the two sides of the bag opening 36 of the packaging bag 31 (reference Fig.13 , the two straightening arms 26 tighten the left side 34 and the right side 35 of the bag opening 36 respectively, so that the bag opening 36 of the packaging bag 31 is tightened and straightened, and when the bag opening 36 is tightened and straightened, the edges of the bag opening 36 are flush and in an upright state, the cylinder rod of the alignment cylinder 7 is shortened again, and the fixing block 14 is driven to reset;

[0048] Then, the cylinder rod of the driving cylinder 8 is shortened, so that the gear 20 and the rack block 18 are meshed in the opposite direction, thereby bringing the straightening arms 26 together. After the gear 20 is disengaged from the rack block 18, the elastic potential energy of the spiral spring 27 is released, so that the pivot 10 rotates in the opposite direction, thereby bringing the straightening arms 26 together. Then, as the sliding seat 28 moves upward, the straightening arms 26 can be pulled out from the bag opening 36 of the packaging bag 31. Then, the conveyor belt 1 is started, and the conveyor belt 1 conveys the packaging bag 31, so that the bag opening 36 of the packaging bag 31 is conveyed to the suture entrance of the sewing machine 3, that is, the suture area 33 of the packaging bag 31 enters the suture entrance of the suture machine 3, so that the suture machine 3 starts to sew the bag opening 36 of the packaging bag 31.
