Description

Technical Field

[0001] The present invention relates to the technical field of ton bags and pallets cleaning, and in particular to a device for automatically cleaning the surface of ton bags and pallets before they enter a workshop. Background Art

[0002] As is well known, ton bags and pallets are both commonly used tools in logistics and transportation. Ton bags, also known as bulk bags, space bags, and flexible bulk bags, are a type of container unit. They are primarily used to hold and transport large quantities of bulk materials, such as chemical raw materials, fertilizers, grain, and minerals. Pallets, on the other hand, serve as a medium for transforming static cargo into dynamic cargo, acting as a loading platform. They are primarily used for the assembly, stacking, handling, and transportation of goods, and are a key innovation in the logistics industry. When transporting food, such as grain, they are typically packed in ton bags, which are then stacked on pallets for handling. Before transporting goods from the warehouse to the loading area, dust must be cleaned from the surfaces of the ton bags and pallets.

[0003] The authorization announcement number is CN219237597U, and the announcement date is 2023-06-23. The patent document is named "An automatic dust removal device for ton bag outer packaging", which includes a dust removal room, a dust blowing outlet is opened on one side of the dust removal room, and a fan housing is fixedly installed on the outer surface of the dust blowing outlet, and a rotating mechanism is fixedly installed inside the dust removal room. The packaged silicon powder ton bag is placed on the material turntable in the dust removal room. At this time, the DC first motor at the bottom of the material turntable is turned on to make the material turntable rotate at a uniform speed, and then by pressing the switch button on one side of the fan housing, the air flow is blown out from the dust blowing outlet, so that the fine silicon powder on the outer surface of the silicon powder ton bag is blown off by the air flow. When the dust falls, the dust is recovered by the dust collector in the dust removal channel, so that there is no need to clean it manually, which reduces the burden on people at work and improves people's work efficiency.

[0004] In the prior art, when cleaning ton bags and pallets, dust removal is generally completed by patting and blowing on their surfaces. During the patting, cleaning and blowing process, a large amount of dust is easily raised and then falls back on the ton bags and pallets. Summary of the Invention

[0031] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0032] like Figure 1-10 As shown, this embodiment provides an automatic surface cleaning device for ton bags and pallets before they enter a workshop, comprising a dust removal box 1, wherein the interior of the dust removal box 1 is provided with a high-pressure blowing mechanism and a cleaning mechanism, wherein the cleaning mechanism comprises a first beating roller 2 and a second beating roller 3, and the top of the dust removal box 1 is connected to a negative pressure dust suction mechanism, which is used to absorb the dust blown and cleaned.

[0033] Specifically, the dust collecting box 1 is a main body structure, which can be a box structure or a building used for dust collection. It is arranged at the material entrance of the workshop, and the dust collecting box 1 is arranged in an upright state. The bottom of the dust collecting box 1 is fixed to a fixed foundation such as the ground, wherein one surface of the dust collecting box 1 such as the front is opened to facilitate the transportation of ton bags and pallets into the dust collecting box 1 for dust collection operation on the front surface of the workshop. The top of the dust collecting box 1 is provided with an opening such as a rolling door. During the dust collection and cleaning process, the rolling door is pulled down to cover the opening of the dust collecting box 1, thereby sealing to prevent part of the dust from floating out of the dust collecting box 1 during the dust collection operation, thereby causing pollution to the workshop; a ton bag pallet placement area is provided at the bottom of the dust collecting box 1, and its setting position is exactly in the center of the dust collecting box 1, and the ton bags and pallets are transported to the ton bag pallet placement area for placement through an external conveying mechanism such as a conveyor belt (not shown in the figure) to facilitate subsequent dust collection operations;

[0034] The core innovation of the embodiment of the present invention is that a high-pressure blowing mechanism and a cleaning mechanism are provided inside the dust removal box 1, and the cleaning mechanism includes a first beating roller 2 and a second beating roller 3. The top of the dust removal box 1 is connected to a negative pressure dust suction mechanism, and the negative pressure dust suction mechanism is used to absorb the dust that is beaten and swept.

[0035] Specifically, the high-pressure blowing mechanism includes a first high-pressure jet head 4 relatively arranged on both sides of the dust removal box 1 and a second high-pressure jet head 5 on the top wall of the dust removal box 1; the first high-pressure jet head 4 and the second high-pressure jet head 5 are used to blow and separate the dust beaten from the surface of the ton bag and the dust on the tray;

[0036] The cleaning mechanism includes two first beating rollers 2 and two second beating rollers 3. The first beating roller 2 includes a horizontally arranged roller shaft and a brush arranged on the roller shaft. The first beating roller 2 is located directly above the ton bag. The movement of the first beating roller 2 is a composite movement of two movements. One is that the first beating roller 2 is driven by a motor to rotate, that is, the rotation of the roller shaft drives the rotation of the brush. The second is a vertical movement, that is, the vertical up and down movement of the first beating roller 2 as a whole is driven by a cylinder. In this way, when cleaning, the first beating roller 2 is driven by a cylinder to move from top to bottom towards the top surface of the ton bag. During this process, a motor drives the first beating roller 2 to rotate to achieve the cleaning of the top surface of the ton bag. The second beating roller 3 can be completely identical to the first beating roller 2 in structure. It only changes the horizontally arranged roller shaft to a vertical one to clean the sides of the ton bag. Obviously, since there are multiple sides of the ton bag, there can be multiple second beating rollers 3 to adapt to the sides of different ton bags.

[0037] In this embodiment, ton bags are loaded on pallets, and the pallets can passively or actively move on the ground to transport the pallets. The two beating rollers mainly beat the ton bags, and the high-pressure blowing mechanism can perform high-pressure blowing treatment on the ton bags and the pallets at the same time.

[0038] The negative pressure dust collection mechanism includes a dust collection hood, a conveying pipe and a collection bin which are connected in sequence through pipes, and is also provided with a negative pressure driving mechanism, wherein the dust collection hood is arranged on the top of the dust collection box 1 and is connected with the interior of the dust collection box 1. In this way, when the high-pressure blowing mechanism and the cleaning mechanism are cleaning the dust, a large amount of dust will float inside the dust collection box 1 (this dust includes the dust on the surface of the ton bag and the dust on the surface of the tray). In this way, by starting the negative pressure driving mechanism such as the fan, the floating dust will be adsorbed and conveyed under the transportation of the dust collection hood and the conveying pipe until it is transported to the collection bin for collection, thereby avoiding a large amount of dust floating inside the dust collection box 1, thereby causing certain pollution.

[0039] Specifically, when cleaning dust, the cylinder drives the first beating roller 2 to move downward from the top to the top surface of the ton bag. During this process, a motor drives the first beating roller 2 to rotate to clean the top surface of the ton bag. Then, another cylinder is started to drive the second beating roller 3 to move from the left to the right to the side of the ton bag. During this process, another motor drives the second beating roller 3 to rotate to clean the side of the ton bag. Since there are multiple sides of the ton bag, there can be multiple second beating rollers 3 to adapt to different sides of the ton bag, thereby cleaning each side of the ton bag.

[0040] Then start the first high-pressure jet head 4 to blow the dust cleaned from the sides to separate it from the surface of the ton bag. At the same time, start the second high-pressure jet head 5 to blow and separate the dust on the pallet, so that the dust on the ton bag and pallet is cleaned.

[0041] During the cleaning process, the dust on the surface of the ton bag and the dust on the tray are scattered inside the dust removal box 1. In this way, by starting the dust collector, the floating dust is adsorbed and transported by the dust hood and the conveying pipe until it is transported to the collection bin for collection.

[0042] Beneficial effects of this embodiment: The negative pressure dust suction mechanism can absorb the dust floating inside the dust removal box 1, avoiding a large amount of dust flying and falling on the ton bags and pallets during the beating, cleaning and blowing process, causing certain pollution.

[0043] For further information, see Figure 2-Figure 9In the above embodiment, the dust on the surface of the ton bag is cleaned by the first beating roller 2 and the second beating roller 3. If the first beating roller 2 and the second beating roller 3 beat the same part each time, a considerable amount of dust may still remain on the surface of the ton bag and is not easily cleaned out by the first beating roller 2 and the second beating roller 3, thereby affecting the cleaning effect.

[0044] Based on this, in order to improve the cleaning effect, this embodiment provides another cleaning mechanism for the side, the interior of the dust removal box 1 is provided with a first motor 6 through a bracket, and a rotating plate 7 is fixedly connected to the output shaft of the first motor 6. Preferably, the bottom of the rotating plate 7 is rotatably connected to the bottom of the dust removal box 1 to reduce the shaking of the rotating plate 7 during the rotation process; an inclined groove 9 is provided on the rotating plate 7, and a sliding block 10 is slidably connected to the interior of the inclined groove 9, and a connecting tube 11 is fixed to the sliding block 10, and the end of the connecting tube 11 passes through the inclined groove 9 and extends to the outside of the inclined groove 9, and the end of the connecting tube extending to the outside of the inclined groove 9 is fixedly connected to a beating rod 12, and the beating rod 12 is used to beat the dust on the surface of the ton bag;

[0045] A strip groove 13 is provided on the inner side wall of the inclined groove 9, and the strip groove 13 is connected to the inclined groove 9, and a plurality of grooves 14, such as two grooves, are provided in parallel on the inner wall of the strip groove 13. A sliding groove 15 is provided on the opening of each groove 14, and a baffle 16 is slidably connected to the inside of the sliding groove 15. The baffle 16 is used to block the opening of the groove 14. A movable groove 17 is provided in the radial direction inside the connecting tube 11, and an adjusting column 20 adapted to the groove 14 is provided inside the movable groove 17. The end of the adjusting column 20 passes through the movable groove 17 and extends to the outside of the movable groove 17. The end of the adjusting column 20 extending to the outside of the movable groove 17 abuts against the inner wall of the strip groove 13. The adjusting column 20 is slidably connected to the movable groove 17, and a limiting spring 18 is provided at the other end of the adjusting column 20. One end of the limiting spring 18 is provided on the inner wall of the movable groove 17, and an extrusion spring 19 is provided on one side of the sliding block 10. One end of the extrusion spring 19 is provided on the side wall of the inclined groove 9.

[0046] The shape of the beating rod 12 is generally L-shaped, and the beating rod 12 includes a curved portion and a vertical portion, the curved portion is close to and connected to the connecting tube 11, and the vertical portion is away from the end of the connecting tube 11. In this embodiment, Figure 4 As shown, when the rotating plate 7 is moved from the initial position (as shown Figure 2The slapping rod 12 is rotated counterclockwise to drive the synchronous rotation of the slapping rod 12, and the slapping rod 12 is made to fit the surface of the ton bag, that is, the vertical portion of the slapping rod 12 is parallel to the surface of the ton bag, thereby increasing the contact area between the vertical portion and the outer surface of the ton bag to better slap the ton bag, rather than horizontally and tilting (not completely fitting with the outer surface of the ton bag), thereby affecting the effect of slapping dust removal. In this way, the dust remaining on the surface of the ton bag is slapped out by the slapping rod 12 to prevent dust from remaining on the surface of the ton bag;

[0047] When the adjusting post 20 is in contact with the inner wall of the strip groove 13, the adjusting post 20 passes through and slides into the groove 14. It should be noted that the groove 14 is formed with a bell mouth to adapt to the adjusting post 20. In this way, the adjusting post 20 can slide in or out of the groove 14 smoothly, avoiding the movement of the adjusting post 20 during the sliding process. In this embodiment, preferably, the elastic coefficient of the limit spring 18 is greater than the elastic coefficient of the extrusion spring 19, that is, when the adjusting post 20 is engaged with the groove 14, it will not be affected by the extrusion spring 19 to make the adjusting post 20 slide out of the groove 14. In this way, the two can be firmly engaged, so that the position of the slapping rod 12 is fixed to slap the dust remaining on the surface of the ton bag.

[0048] The sliding groove 15 is connected to the groove 14, and the sliding groove 15 is opened at the opening of the groove 14. In this way, the blocking piece 16 blocks the opening of the groove 14 through the sliding stroke in the sliding groove 15. It should be noted that in the initial state, the blocking piece 16 stays at the bottom of the sliding groove 15 under the action of gravity, that is, it does not block the opening of the groove 14. When the adjusting column 20 slides obliquely downward on the inner wall of the strip groove 13, it first slides into the groove 14 and then slides out of the groove 14, and then slides against the surface of the blocking piece 16. At this time, the blocking piece 16 does not move, that is, when the adjusting column 20 slides obliquely downward, the blocking piece 16 does not move in the sliding groove 15.

[0049] When the adjusting post 20 slides obliquely upward on the inner wall of the strip groove 13, that is, the adjusting post 20 is located below the two grooves 14, when the adjusting post 20 slides against the strip groove 13 and slides obliquely upward, the end of the adjusting post 20 slides against the baffle 16, and through the action of friction, drives the baffle 16 to slide obliquely upward together (preferably, the surface of the baffle 16 can be set to a frosted surface to increase friction). In this way, the baffle 16 slides against the opening of the groove 14 to prevent the adjusting post 20 from entering the groove 14, so that the adjusting post 20 slides smoothly to the top of the inner wall of the strip groove 13, that is, above the two grooves 14. At this time, Figure 4 As shown;

[0050] In the above description, the baffle 16 has two states:

[0051] When the blocking piece 16 is in the first state, that is, the blocking piece 16 is located at the bottom of the sliding groove 15 and does not slide;

[0052] When the blocking piece 16 is in the second state, the blocking piece 16 slides, that is, the blocking piece 16 slides obliquely upward on the sliding groove 15. In this way, the blocking piece 16 blocks the opening of the groove 14, so that the adjustment column 20 slides smoothly to the top of the inner wall of the strip groove 13 (the initial position), thereby preventing the adjustment column 20 from entering the groove 14 during the oblique upward sliding process, and thus sliding smoothly to the initial position;

[0053] Specifically, when switching from the first state to the second state, by starting the first motor 6, the first motor 6 drives the rotating plate 7 to rotate, driving the slapping rod 12 on the rotating plate 7 to slap and contact the outer surface of the ton bag, thereby slapping and cleaning the dust on the surface of the ton bag, and in the slapping process, the slapping rod 12 is squeezed to drive the sliding block 10 to slide obliquely downward in the inclined groove 9, so that the adjusting column 20 passively slides obliquely downward along the strip groove 13, thereby sliding into the groove 14, so that the position where the slapping rod 12 is squeezed and moved is locked. Similarly, by continuing to slap after locking, the adjusting column 20 is squeezed out of the previous groove 14 and enters the next groove 14. In this process, the adjusting column 20 slides obliquely downward on the surface of the baffle 16, and the baffle 16 does not slide at this time;

[0054] When the first motor 6 continues to start, causing the beating rod 12 to hit the surface of the ton bag again, the adjusting column 20 also slides out of the last groove 14 and abuts against the surface of the baffle 16. At this time, since there is no subsequent groove 14 to lock the adjusting column 20, the rebound of the extrusion spring 19 pushes the adjusting column 20 and the baffle 16 to slide obliquely upward. Since the baffle 16 blocks the opening of the groove 14, the adjusting column 20 slides smoothly to the initial position;

[0055] In the above description, the switching action from the first state to the second state is assisted by the sliding direction of the adjusting column 20; that is, when the adjusting column 20 slides obliquely downward, the adjusting column 20 slides into or out of the two grooves 14 in turn. During this process, the adjusting column 20 is engaged and locked with the two grooves 14 in turn, so that the beating rod 12 is fixed at different positions, thereby beating different parts of the surface of the ton bag, thereby achieving the effect of uniform beating and cleaning the ton bag; at the same time, when the adjusting column 20 slides obliquely upward, the adjusting column 20 slides and abuts the two baffles 16 on the two grooves 14 in turn, thereby blocking the openings of the two grooves 14, so that the adjusting column 20 slides smoothly to the initial position, completing a cycle of beating and cleaning, and repeating this cycle, so as to uniformly beat and clean the dust on the surface of the ton bag until it is cleaned.

[0056] Preferably, the connection relationship between the curved portion and the vertical portion on the beating rod 12 is a rotational connection. In this way, when the beating rod 12 is beating to clean the dust on the surface of the ton bag, the ton bag has a reaction force on the beating rod 12, thereby driving the vertical portion to move in the vertical direction on the surface of the ton bag, that is, the vertical portion rotates on the curved portion, thereby frictionally cleaning the dust remaining on the surface of the ton bag, so as to improve the effect of cleaning the dust on the surface of the ton bag.

[0057] In this embodiment, the above-mentioned structure for improving the cleaning effect is to beat and clean the dust on the side of the ton bag. Obviously, since there are multiple sides of the ton bag, there can be multiple beating rods 12 to adapt to different sides of the ton bag.

[0058] Specifically, when cleaning the dust on the surface of the ton bag, the first motor 6 is started to drive the rotating plate 7 to rotate, driving the beating rod 12 on the rotating plate 7 to beat the outer surface of the ton bag, thereby beating out the dust remaining on the surface of the ton bag, separating the dust from the ton bag, and preventing the dust from remaining on the surface of the ton bag, thereby affecting the cleaning effect;

[0059] The first motor 6 is started again to drive the beater bar 12 to rotate, so that the beater bar 12 will beat the dust at different positions on the surface of the ton bag at the locked position.

[0060] When the adjusting column 20 slides obliquely downward and slides through the two grooves 14, in order to restore the adjusting column 20 to its initial position for the next cycle of beating and cleaning the dust on the surface of the ton bag, when the adjusting column 20 slides obliquely upward, it slides against the surface of the baffle 16 to drive the baffle 16 to slide obliquely upward together, so that the baffle 16 blocks the opening of the groove 14. In this way, the adjusting column 20 can smoothly slide to the initial position for the next cycle of beating and cleaning.

[0061] For further information, see Figure 10 In the above embodiment, when the adjusting column 20 slides obliquely upward, it slides against the surface of the blocking piece 16 to drive the blocking piece 16 to slide obliquely upward together, so that the blocking piece 16 blocks the opening of the groove 14. However, when the blocking piece 16 slides obliquely upward together, the blocking piece 16 slides to the top of the sliding groove 15, that is, the opening of the groove 14 is blocked by the blocking piece 16.

[0062] Since the blocking piece 16 and the sliding groove 15 are slidably connected, the friction generated between the two can easily cause the blocking piece 16 to be stuck in the sliding groove 15, so that the blocking piece 16 cannot slide to the initial position under the action of gravity. When the adjustment column slides downward, it cannot enter the groove 14 for engagement.

[0063] Based on this, in order to prevent the adjustment column 20 from sliding obliquely downward and failing to enter the groove 14 for clamping and fixing, that is, the adjusted position of the beating rod 12 cannot be locked, thereby affecting the normal progress of beating and cleaning.

[0064] This embodiment provides a structure to prevent the baffle 16 from being stuck at the opening of the groove 14. The sliding groove 15 is divided by the groove 14 into a first groove body 151 and a second groove body 152 arranged up and down. The second groove body 152 is deeper than the first groove body 151. The purpose of its setting is that when the baffle 16 slides obliquely upward, the depth of the shallow groove 151 cannot accommodate the thickness of the baffle 16, so it can only slide to the side wall of the opening of the groove 14. When the adjustment column 20 and the baffle 16 are separated, if the baffle 16 cannot automatically slide to the initial position At this time, when the adjusting column 20 slides downward for the next time, it first slides along the inner wall of the strip groove 13, then slides into the shallow groove 151, and pushes the blocking piece 16 to slide downward passively, so that the blocking piece is removed from the opening of the groove 14, so that the adjusting column 20 can enter the groove 14 and engage, so that when the adjusting column 20 slides downward, it can be smoothly engaged into the groove 14, preventing the adjusting column 20 from being unable to engage with the groove 14, so that the adjusted position of the slapping rod 12 cannot be locked, and thus the dust on the surface of the ton bag cannot be cleaned.

[0065] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims.
