Description

Technical Field

[0001] This utility model relates to the technical field of flour palletizing equipment, and in particular to a dust removal mechanism for a flour palletizing machine. Background Technology

[0002] After flour is bagged, it is usually stacked to save space and facilitate transportation. (See reference...) Figure 1 Existing flour stacking equipment generally includes a conveyor for conveying flour upwards, a lifting platform for receiving, a pallet placed on the lifting platform for use by forklifts, a stacking robot for moving flour bags from the conveyor to the pallet, and guide rails for the reciprocating motion of the stacking robot.

[0003] During operation, the stacking robot picks up flour bags and places them on top of a pallet, then stacks them on the pallet in a free-fall manner. When the flour bags fall, they kick up a lot of flour dust, which is flammable and dangerous. Inhaling the dust for a long time can also cause physical discomfort. Utility Model Content

[0004] The purpose of this invention is to alleviate the problem of excessive flour dust caused by falling flour bags, as mentioned in the background art, by proposing a dust removal mechanism for a flour palletizing machine.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A dust removal mechanism for a flour palletizing machine includes a negative pressure dust collection box connected to a stacking robot. The negative pressure dust collection box is located on the side of the stacking robot closer to the lifting platform. The negative pressure dust collection box has a chamber, a perforated plate communicating with the chamber, and a negative pressure dust collection port communicating with the chamber. The negative pressure dust collection port is connected to a negative pressure dust collection device. When the stacking robot moves upward toward the lifting platform, the chamber gradually shrinks; when the stacking robot moves toward the conveyor, the chamber gradually expands.

[0007] The dust removal mechanism includes a partition, at least a portion of which is a wall of the chamber. The side of the partition near the conveyor forms the chamber with a portion of the inner wall of the negative pressure dust collection box. The partition is fixedly positioned relative to the guide rail and is slidably connected to the negative pressure dust collection box.

[0008] The dust removal mechanism includes a support rod, which is fixedly installed with the guide rail and the partition plate, with the support rod located on the side of the partition plate away from the chamber.

[0009] The support rod is slidably guided by the negative pressure dust collection box.

[0010] The dust removal mechanism includes a guide bracket and a connecting rod. One end of the connecting rod is fixed to the stacking robot, and the other end of the connecting rod is fixed to the guide bracket. The guide bracket is slidably connected to the guide rail.

[0011] The negative pressure dust collection box has a plate body on the side near the lifting platform. The plate body includes an integrally formed non-perforated plate and a perforated plate. The perforated plate is located near the stacking robot, and the non-perforated plate is located away from the stacking robot. The bottom plane of the partition is tangent to the top surface of the plate body.

[0012] The dust removal mechanism for a flour palletizing machine proposed in this utility model has the following advantages: This device achieves efficient dust capture and removal during the dropping and clamping of flour bags through the coordinated movement of the negative pressure dust collection box and the chamber structure. When the chamber shrinks, it helps to concentrate dust; when it expands, it enhances the suction force of the through-holes. Combined with the negative pressure dust collection equipment, this forms a dual suction force, which can significantly improve dust collection efficiency, improve the working environment, and reduce dust pollution and safety hazards.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] Reference Figures 2-3 A dust removal mechanism for a flour palletizing machine includes a negative pressure dust collection box 5 connected to a stacking robot 2. The negative pressure dust collection box 5 is located on the side of the stacking robot 2 near the lifting platform. The negative pressure dust collection box 5 has a chamber 8, a perforated plate 10 communicating with the chamber 8, and a negative pressure dust collection port 11 communicating with the chamber 8. The negative pressure dust collection port 11 is connected to a negative pressure dust collection device, such as a vacuum cleaner. When the stacking robot 2 moves upward toward the lifting platform, the chamber 8 gradually shrinks. When the stacking robot 2 moves toward the conveyor, the chamber 8 gradually expands.

[0019] When this device is working, the negative pressure suction equipment continuously generates negative pressure suction force on the negative pressure suction port 11, so that the through hole of the perforated plate 10 is in a suction state. (Reference) Figure 3 When the stacking robot 2 moves upwards towards the lifting platform to drop the flour bags, the negative pressure dust collection box 5 moves away from the lifting platform, and the chamber 8 gradually shrinks. The shrinking of the chamber 8 helps to gather the dust absorbed in the entire chamber together, so that it can be better sucked away by the negative pressure dust collection port 11. When the stacking robot 2 moves towards the conveyor to pick up the flour bags on it, the negative pressure dust collection box 5 moves directly above the lifting platform, and can better suck away the dust scattered when the flour bags are dropped through the through holes of the perforated plate 10. At this time, because the chamber 8 is gradually expanding, the expansion of the chamber 8 will cause the suction force of the through holes of the perforated plate 10 to increase. Under the combined action of the suction force generated by the expansion of the chamber and the suction force of the negative pressure dust collection device, the dust in the air can be sucked away more powerfully.

[0020] As one implementation method for enlarging and shrinking the chamber, the dust removal mechanism includes a partition 7, which at least partially forms part of the wall of the chamber 8. The side of the partition 7 near the conveyor and part of the inner wall of the negative pressure dust collection box 5 form the chamber 8. The partition 7 is fixedly positioned relative to the guide rail 1, and the partition 7 is slidably connected to the negative pressure dust collection box 5. Because the partition 7 is relatively fixed to the guide rail, while the negative pressure dust collection box 5 is slidably connected to the partition 7, the relative positional relationship between the negative pressure dust collection box 5 and the partition 7 can be used to enlarge and shrink the chamber 8 when the negative pressure dust collection box 5 moves left and right with the stacking robot 2, resulting in a simple structure.

[0021] In one embodiment, the dust removal mechanism includes a support rod 6, which is fixedly installed with the guide rail 1. The support rod 6 is fixed with the partition 7, and the support rod 6 is located on the side of the partition 7 away from the chamber 8. The support rod 6 supports the partition 7 so that the position of the partition 7 will not move when the negative pressure dust collection box 5 moves left and right.

[0022] The support rod 6 is slidably guided to the negative pressure dust collection box 5, so that the support rod 6 can guide the movement of the negative pressure dust collection box 5, making the left and right movement of the negative pressure dust collection box 5 more stable.

[0023] As one installation method for the negative pressure dust collection box 5, the dust removal mechanism includes a guide bracket 4 and a connecting rod 3. One end of the connecting rod 3 is fixed to the stacking robot 2, and the other end of the connecting rod 3 is fixed to the guide bracket 4. The guide bracket 4 is slidably connected to the guide rail 1. When the stacking robot 2 moves left and right, it drives the negative pressure dust collection box 5 below the guide bracket 4 to move left and right. Of course, the negative pressure dust collection box 5 can also be directly fixed to the support frame of the stacking robot 2, and the stacking robot 2 can directly drive the negative pressure dust collection box 5 to move left and right.

[0024] It should be noted that the negative pressure dust collection box 5 of this device is relatively fixed to the support frame of the stacking robot 2, and the gripping and releasing parts of the stacking robot 2 located within the support frame can have multiple degrees of freedom.

[0025] refer to Figure 2 The negative pressure dust collection box 5 is a plate body on the side near the lifting platform. The plate body includes an integrally set non-perforated plate 9 and a perforated plate 10. The perforated plate 10 is set close to the stacking robot 2, and the non-perforated plate 9 is set away from the stacking robot 2. The bottom plane of the partition 7 is tangent to the top surface of the plate body.

[0026] The bottom plane of the partition 7 is tangent to the top surface of the plate to better collect the dust on the plate when the partition 7 and the negative pressure dust collection box 5 move relative to each other. The bottom plate of this device is equipped with a non-perforated plate 9 and a perforated plate 10 to avoid wasting too many dust collection holes in places where no dust falls. In this way, the non-perforated plate 9 will not have a significant impact on the suction power of the through holes of the perforated plate 10.

[0027] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any technical solution, concept, or design obtained by those skilled in the art by making equivalent substitutions or changes based on the technical solution and utility model concept disclosed in the present utility model should be included within the protection scope of the present utility model.
