DETAILED DESCRIPTION

[0041] Embodiments of the present application are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below by reference to the drawings are exemplary and are intended to explain the present application, and cannot be understood as a limitation of the present application.

[0042] As Figures 1 to 11 shown, the food packaging bag cleaning device of the present application comprises a cleaning pool 1, a conveying assembly 2, and a flushing assembly 3. The cleaning pool 1 is provided with an inclined part 4, the end of the inclined part 4 away from the cleaning pool 1 is inclined upward, the flushing assembly 3 is installed on the inclined part 4, and the conveying assembly 2 is arranged on the cleaning pool 1 and the inclined part 4 to drive the packaging bags to pass through the cleaning pool 1 and the inclined part 4 in turn. The cleaning liquid for cleaning the packaging bags is placed in the cleaning pool 1, the flushing assembly 3 is located outside the cleaning liquid, the conveying assembly 2 conveys the packaging bags into the cleaning pool 1 for cleaning, then drives the packaging bags to move out of the cleaning pool 1 and into the inclined part 4, and when the packaging bags pass through the flushing assembly 3, the flushing assembly 3 flushes the packaging bags, thus completing the cleaning of the packaging bags.

[0043] Referring to Figure 1 , Figure 2 , Figure 4 , the conveying assembly 2 is provided with a placing assembly 5, the placing assembly 5 is provided with multiple groups, and the multiple groups of placing assemblies 5 are arranged along the conveying direction of the conveying assembly 2. In this embodiment, the conveying direction of the packaging bags is from left to right, that is, the packaging bags move to the inclined part 4 after passing through the cleaning liquid on one side of the cleaning pool 1. The cleaning pool 1 is provided with a guide assembly 6, the guide assembly 6 is installed on the inclined part 4, and the guide assembly 6 is located outside the cleaning pool 1.

[0044] The placing assembly 5 is used for placing the packaging bags. When the conveying assembly 2 conveys the packaging bags, the placing assembly 5 moves the packaging bags out of the cleaning pool 1. After the placing assembly 5 moves to the outside of the cleaning pool 1, the placing assembly 5 cooperates with the guide assembly 6, the guide assembly 6 drives the placing assembly 5 to swing to remove the excess packaging bags on the placing assembly 5, the removed packaging bags enter the next group of placing assemblies 5, so that the packaging bags are arranged and placed in one layer on the placing assembly 5, reducing the stacking phenomenon of the packaging bags on the placing assembly 5, and then the placing assembly 5 drives the packaging bags to pass through the flushing assembly 3 for flushing, thus eliminating the phenomenon that the stacking packaging bags affect the flushing effect.

[0045] Referring to Figure 6 , Figure 7 , Figure 8The placing assembly 5 comprises a partition plate 51, an intermediate plate 52, a bottom plate 53 and a side plate 54. The intermediate plate 52 is connected to the conveying assembly 2. The bottom plate 53 is arranged on a side of the intermediate plate 52 away from the conveying assembly 2 and is connected to the intermediate plate 52. The side plate 54 is connected to the bottom plate 53 and is located on a side of the bottom plate 53 away from the conveying direction of the packaging bag. The partition plate 51 is located on a side of the bottom plate 53 away from the intermediate plate 52. The partition plate 51 is provided in a plurality of pieces, and the plurality of partition plates 51 are arranged along a direction perpendicular to the conveying direction of the packaging bag. Two adjacent partition plates 51 are arranged at intervals, so that a placing cavity 511 for placing the packaging bag is formed between the two adjacent partition plates 51.

[0046] The conveying assembly 2 drives the side plate 54 and the partition plate 51 to move through the intermediate plate 52 and the bottom plate 53. When the side plate 54 is moved out of the cleaning pool 1, the side plate 54 drives the packaging bag to be synchronously moved out of the cleaning pool 1, so that the packaging bag is located in the placing cavity 511 between the partition plates 51. When the placing assembly 5 swings, the packaging bag outside the placing cavity 511 is removed from above the partition plate 51, so that the phenomenon of stacking of the packaging bag is avoided, and subsequent cleaning is facilitated.

[0047] Referring to Figure 2 , Figure 7 , Figure 8 The intermediate plate 52 is rotationally connected to the conveying assembly 2 and is arranged along a direction perpendicular to the conveying direction of the packaging bag. A spring 521 is arranged between the intermediate plate 52 and the conveying assembly 2. The spring 521 is a torsion spring and is connected to the intermediate plate 52 and the conveying assembly 2, respectively. The spring 521 is used to drive the intermediate plate 52 to rotate to a state perpendicular to the conveying direction of the packaging bag. When the intermediate plate 52 passes through the guide assembly 6, the intermediate plate 52 swings and drives the bottom plate 53 to swing.

[0048] Referring to Figure 6 , Figure 7 , Figure 8 A clamping plate 512 is arranged at an upper end of the partition plate 51, i.e., the clamping plate 512 is located on a side of the partition plate 51 away from the bottom plate 53 and is located above the placing cavity 511. The clamping plate 512 is used to block the packaging bag entering the placing cavity 511, so that the phenomenon of the packaging bag being separated from the placing cavity 511 is reduced when the bottom plate 53 swings.

[0049] Referring to Figure 4 , the figure, Figure 6 , Figure 7The guiding assembly 6 comprises a first guiding plate 61 and a second guiding plate 62, the first guiding plate 61 and the second guiding plate 62 are arranged on the two sides of the conveying assembly 2, that is, the first guiding plate 61 and the second guiding plate 62 are arranged on the two sides of the middle plate 52, and the first guiding plate 61 and the second guiding plate 62 are arranged in the same plane. A plurality of first baffles 611 are arranged on the side of the first guiding plate 61 close to the middle plate 52, the plurality of first baffles 611 are arranged in the conveying direction of the packaging bag, and every two adjacent first baffles 611 are arranged at intervals, and a plurality of second baffles 621 are arranged on the second guiding plate 62, the second baffles 621 are arranged in the conveying direction of the packaging bag, and every two adjacent second baffles 621 are arranged at intervals, that is, the arrangement mode of the second baffles 621 on the second guiding plate 62 is the same as that of the first baffles 611 on the first guiding plate 61.

[0050] With reference to Figure 6 , Figure 7 , the first guiding plate 61 and the second guiding plate 62 are arranged in the same plane. When the first guiding plate 531 and the second guiding plate 532 move to the inclined part 4, the first guiding plate 531, the second guiding plate 532, the first baffle 611 and the second baffle 621 are located in the same plane, and the first guiding plate 531 is located on the same straight line as the plurality of first baffles 611, and the second guiding plate 532 is located on the same straight line as the plurality of second baffles 621.

[0051] With reference to Figure 4 , Figure 5 , Figure 11 , the second baffle 621 is located between the first baffle 611 and the flushing assembly 3, that is, when the bottom plate 53 moves, it will pass through the first baffle 611 first and then pass through the second baffle 621.

[0052] When the first guiding plate 531 moves to the first baffle 611, the first guiding plate 531 abuts against the first baffle 611, driving the bottom plate 53 to tilt, and at this time, the bottom plate 53 is located above the inclined part 4, so that the angle of the bottom plate 53 is the same as the angle of the inclined part 4, and the bottom plate 53 is tilted again under the action of the first baffle 611, the excess packaging bags on the bottom plate 53 are not entered into the placing cavity 511, and under the action of the tilted bottom plate 53, they are moved to fall off from the bottom plate 53, and only the packaging bags in the placing cavity 511 are reserved.

[0053] When the first guide rod 531 is separated from one of the first baffles 611, the elastic member 521 drives the middle plate 52 to reset. When the first guide rod 531 sequentially passes through the plurality of first baffles 611, the middle plate 52 and the bottom plate 53 move back and forth to achieve the effect of vibration, which is more convenient for removing the excess packaging bags on the bottom plate 53. At the same time, the bottom plate 53 vibrates to facilitate the packaging bags to enter the corresponding placement cavity 511.

[0054] After the first guide rod 531 is separated from the first baffle 611, the second guide rod 532 moves to the second baffle 621, and the second guide rod 532 drives the other side of the bottom plate 53 to tilt in the opposite direction. The second guide rod 532 and the plurality of second baffles 621 are matched to also be able to drive the bottom plate 53 to vibrate. By adjusting the bottom plate 53 to tilt in different directions and vibrate, it is more convenient for the packaging bags to enter the placement cavity 511.

[0055] Referring to Figure 7 , Figure 8 , Figure 9 The bottom plate 53 is rotationally connected with the middle plate 52, and the rotation shaft of the bottom plate 53 is arranged below the side plate 54. A torsion spring (not shown in the figure) is arranged between the bottom plate 53 and the middle plate 52, and the two ends of the torsion spring are respectively connected with the bottom plate 53 and the middle plate 52. The torsion spring is used to drive the bottom plate 53 and the middle plate 52 to abut. A top block 7 is arranged on the inclined portion 4, and the top block 7 and the first guide plate 61 are arranged on the same side of the inclined portion 4. The top block 7 includes a smooth portion 72 and a pushing portion 71. The smooth portion 72 is located at the top of the top block 7, and the pushing portion 71 has two, and the two pushing portions 71 are respectively located on the two sides of the top block 7. The pushing portion 71 is arranged obliquely.

[0056] After the second guide rod 532 is separated from the second guide plate 62, the first guide rod 531 moves to abut against the pushing portion 71. Under the action of the inclined pushing portion 71, the first guide rod 531 gradually moves to the smooth portion 72, and the torsion spring is twisted under stress. When the first guide rod 531 moves to the smooth portion 72, the distance between the first guide rod 531 and the rotation shaft of the bottom plate 53 is the same as the distance that the first guide rod 531 moves relative to the conveying assembly 2. When the first guide rod 531 moves to the smooth portion 72, the bottom plate 53 is driven to rotate to 90 degrees. The packaging bags in the placement cavity 511 are transferred from the placement cavity 511 to the side plate 54, and the packaging bags are turned over at the same time. When the first guide rod 531 passes through the other pushing portion 71, the torsion spring drives the bottom plate 53 to rotate again to abut against the middle plate 52, and the packaging bags are turned over again and enter the placement cavity 511 at the same time.

[0057] A limiting plate 541 is arranged on the side panel 54, the limiting plate 541 is arranged on the side of the side panel 54 away from the bottom plate 53, the limiting plate 541 is perpendicular to the side panel 54 and is located on the side of the side panel 54 close to the bottom plate 53. When the packaging bag is turned over, the packaging bag is transferred from the bottom plate 53 to the side panel 54, and the limiting plate 541 is used to block the packaging bag, thereby reducing the phenomenon that the packaging bag is separated from the side panel 54.

[0058] With reference to Figure 10 , the flushing assembly 3 includes a first flushing part 31 and a second flushing part 32, the first flushing part 31 is located above the smooth part 72, and the second flushing part 32 is located on the side of the top block 7 away from the first guide plate 61.

[0059] With reference to Figure 9 , when the first guide rod 531 moves to the smooth part 72, the packaging bag is turned over, and the first flushing part 31 is used to flush the packaging bag for the first time. After the first guide rod 531 is separated from the push part 71, the packaging bag is turned over again to clean the other side of the packaging bag.

[0060] In other embodiments, the second flushing part 32 can be arranged on the side of the top block 7 close to the first guide plate 61, that is, when the first guide rod 531 does not move to the top block 7, the second flushing part 32 is used to clean the packaging bag first. Then, after the first guide rod 531 moves to the smooth part 72 to turn over the packaging bag, the first flushing part 31 is used to clean the other side of the packaging bag.

[0061] In order to facilitate the turning over of the packaging bag, a clamping plate 512 is arranged on the side of the partition plate 51 away from the first guide plate 61. When the first guide rod 531 cooperates with the first baffle 611 to drive the bottom plate 53 to swing, the packaging bag abuts against the partition plate 51 where the clamping plate 512 is arranged. At this time, the side of the packaging bag is below the clamping plate 512. When the second guide rod 532 cooperates with the second baffle 621, the packaging bag is driven to move in the opposite direction in the placing cavity 511, so that the packaging bag moves out from below the clamping plate 512, so as to facilitate subsequent turning over, and reduce the phenomenon that the clamping plate 512 interferes with the packaging bag to separate from the placing cavity 511.

[0062] With reference to Figure 10 , the first flushing part 31 and the second flushing part 32 have the same structure, wherein the first flushing part 31 includes a water pipe 311 and a plurality of nozzles 312 arranged on the water pipe 311. The water pipe 311 is arranged perpendicular to the conveying direction of the packaging bag, and the nozzles 312 are arranged towards the conveying assembly 2. When the packaging bag passes through the nozzles 312, the nozzles 312 flush the packaging bag with water.

[0063] With reference to Figure 1 , Figure 2The conveying component 2 includes a conveyor belt 21 and a chain 22. The chain 22 is arranged on the side of the conveyor belt 21, and the chain 22 is connected to the driving source. The driving source can be set to a motor with gears. The gears are engaged with the chain 22. The motor drives the chain 22 to rotate through the gears, thereby driving the conveyor belt 21 to rotate.

[0064] Reference Figure 1 、 Figure 2 The conveyor belt 21 includes a plurality of arranged conveyor plates 211. Intermediate plates 52 are mounted on the conveyor plates 211, each having a mounting slot 212. Spring members 521 are disposed within the mounting slot 212 and connected to the intermediate plates 52. This allows the intermediate plates 52 to rotate with the conveyor plates 211 while also abutting against them. This reduces the risk of impurities or the conveyor belt 21 entering between the intermediate plates 52 and the conveyor plates 211, ensuring the stability of the intermediate plates 52. A guide wheel 8 is provided on the cleaning tank 1. The guide wheel 8 cooperates with the chain 22 and is located at a turning point or corner of the chain 22, allowing the chain 22 to rotate in a predetermined direction. A guide wheel 8 is also provided at the junction of the cleaning tank 1 and the inclined portion 4. This ensures that the conveyor belt 21 remains horizontal when within the cleaning tank 1, cleaning the packaging bags. When at the inclined portion 4, the conveyor belt 21 maintains the same inclination angle as the inclined portion 4, rinsing the packaging bags. A cover plate 81 is provided inside the cleaning tank 1 , and the cover plate 81 covers the outside of the guide wheel 8 to block the guide wheel 8 and reduce the phenomenon that the packaging bag is drawn into between the guide wheel 8 and the chain 22 .

[0065] Reference Figure 1 、 Figure 3 A channel 9 is provided at the bottom of the cleaning pool 1 for the conveyor belt 21 to pass through. The channel 9 is not connected to the inside of the cleaning pool 1. After the conveyor belt 21 separates from the inclined portion 4, it enters the channel 9 and then enters the cleaning pool 1 again through the channel 9 to continue cleaning and rinsing the packaging bags.

[0066] Reference Figure 3 Conveyor belt 21 is spaced apart from the bottom of cleaning tank 1. An air inlet pipe 91 is provided on cleaning tank 1, with one end of air inlet pipe 91 located below conveyor belt 21, near cleaning tank 1. Conveyor belt 21 may have multiple through-holes evenly distributed throughout the conveyor belt 21, and multiple air inlet pipes 91 may also be provided. After packaging bags enter cleaning tank 1, air is ventilated into the cleaning tank 1 through air inlet pipe 91, forming bubbles. These bubbles are evenly distributed within the cleaning tank 1 through the through-holes, ensuring more complete contact between the bubbles and the packaging bags, improving the cleaning effect.

[0067] Reference Figure 3In addition, the water inlet pipe 92 and the water outlet pipe 93 are arranged on the cleaning tank 1, so that the cleaning liquid is introduced into the cleaning tank 1 through the water inlet pipe 92, and the cleaning liquid is discharged from the cleaning tank 1 through the water outlet pipe 93 after the cleaning is completed.

[0068] The implementation principle of the present application is that the conveying assembly 2 drives the packaging bag into the cleaning tank 1 for cleaning, and after the cleaning is completed, the conveying assembly 2 moves the packaging bag out of the cleaning tank 1 through the side plate 54, so that the packaging bag is located on the bottom plate 53 and moves with the conveying assembly 2. When the first guide rod 531 moves to the first baffle 611, the first guide rod 531 cooperates with the plurality of first baffles 611 and is driven by the elastic member 521, so that the bottom plate 53 is in reciprocating vibration and reciprocating inclination, so that the packaging bag enters the placement cavity 511, and the excess packaging bag falls off the bottom plate 53.

[0069] After the first guide rod 531 is separated from the first baffle 611, the second guide rod 532 moves to the second baffle 621, and the second guide rod 532 cooperates with the second baffle 621, and is driven by the elastic member 521 to tilt and vibrate the bottom plate 53 in the opposite direction, thereby correcting the position of the packaging bag and removing the residual cleaning liquid on the packaging bag.

[0070] Subsequently, the bottom plate 53 drives the first guide rod 531 to cooperate with the pushing part 71 on the top block 7, and when the first guide rod 531 moves to the smooth part 72, the bottom plate 53 is driven to rotate 90 degrees relative to the middle plate 52, the packaging bag is turned over, and the turned-over packaging bag is transferred to the side plate 54, and then the packaging bag is cleaned by the first flushing part 31. After the first guide rod 531 is separated from the top block 7, the torsional spring drives the bottom plate 53 to rotate to the initial state, so that the packaging bag enters the placement cavity 511 again, the packaging bag is turned over, and then the other side of the packaging bag is flushed by the second flushing part 32, so as to improve the flushing effect of the packaging bag. At the same time, the packaging bag is placed in the corresponding placement cavity 511 by the oscillation of the bottom plate 53, so as to reduce the stacking phenomenon of the packaging bag during flushing, and ensure the flushing effect of the packaging bag.

[0071] Although the embodiments of the present application have been shown and described above, it should be understood that the above embodiments are exemplary and should not be construed as limiting the present application, and those skilled in the art can make changes, modifications, replacements and variations to the above embodiments within the scope of the present application.
