Description

Technical Field

[0001] This application relates to the field of flexible intermediate bulk containers, and in particular to a cleaning device for the interior of a flexible intermediate bulk container. Background Art

[0002] Flexible intermediate bulk containers, also known as flexible bulk bags, ton bags, space bags, etc., are a type of container for unitized loading. They are flexible transport packaging containers with the advantages of moisture-proof, dust-proof, radiation-resistant, firm and safe, and have sufficient strength in structure. Since flexible intermediate bulk containers are very convenient for loading, unloading and handling, and the loading and unloading efficiency is significantly improved, they have developed rapidly in recent years. Flexible intermediate bulk containers are generally woven from polyester fibers such as polypropylene and polyethylene.

[0003] In current social life, when cleaning dust, lint, sundries, etc. inside a flexible intermediate bulk container, it is often necessary to use a blower in cooperation with the flexible intermediate bulk container to expand the space of the flexible intermediate bulk container, facilitating the staff to clean the interior of the flexible intermediate bulk container.

[0004] In the related art, a Chinese patent with the authorization announcement number CN220258975U discloses an interior cleaning machine for flexible intermediate bulk containers, including a working housing. One outer surface of the working housing is fixedly communicated with an air inlet pipe, and one end of the air inlet pipe is fixedly installed with a blower. An air outlet hole is opened at the top of the working housing, and a flexible intermediate bulk container is fixedly arranged at the top of the working housing. A fixing mechanism is fixedly arranged at the top of the working housing. The fixing mechanism includes a plurality of threaded pipes, and the bottom ends of the threaded pipes are fixedly connected with the top of the working housing. Threaded rods are threadedly connected inside the plurality of threaded pipes, and one end of each threaded rod penetrates to the outside of the threaded pipe. Two sliding grooves are opened at the top of the working housing, and sliders are slidably connected inside the two sliding grooves.

[0005] Among them, the flexible intermediate bulk container is sleeved on a plurality of threaded pipes, and the positions of the threaded pipes on the working housing are fixed, that is, the diameter of the circle formed by the plurality of threaded pipes is fixed, so that flexible intermediate bulk containers of different sizes cannot be sleeved on the plurality of threaded pipes, and the applicability is poor, so it needs to be improved. Summary of the Invention

[0006] In order to solve the problem that the threaded pipes cannot support flexible intermediate bulk containers of different sizes, this application provides a cleaning device for the interior of a flexible intermediate bulk container.

[0007] The cleaning device for the interior of a flexible intermediate bulk container provided by this application adopts the following technical solutions: A bulk bag internal cleaning device, including a workbench, a work rack is provided on the workbench, and a number of positioning rods for sleeving the bulk bag are connected to the work rack through a moving component. The moving component includes a moving gear and a number of transmission gears. The moving gear and the transmission gears are all rotatably connected to the work rack. The number of transmission gears are arranged at intervals along the circumference of the moving gear, and the transmission gears are engaged with the moving gear. A number of positioning racks are slidably connected to the work rack. The number of positioning racks are arranged radially with the center of the moving gear as the center of the circle. The number of positioning racks correspond to the positioning rods one by one. The positioning rack is engaged with one transmission gear, and the positioning rod is fixed to the positioning rack. A blower is provided on one side of the work rack, and the output end of the blower faces the moving gear.

[0008] By adopting the above technical solution, during use, the bulk bag is sleeved on a number of positioning rods, and then the moving gear is driven to rotate. Since the moving gear is engaged with the transmission gears, a number of transmission gears rotate synchronously, so as to drive a number of positioning racks to drive the positioning rods to move the same distance along the diameter direction of the moving gear at the same time, that is, a number of positioning rods gather or spread at the same time until a number of positioning rods simultaneously abut against the inner wall of the bulk bag to realize the support of the bulk bag. Then start the blower, and blow air into the bulk bag through the opening of the bulk bag, so that the bulk bag is in an inflated and hollow state, which is convenient for cleaning the inside of the bulk bag.

[0009] Among them, a number of positioning rods can gather or spread at the same time, so that the center of the circle formed by a number of positioning rods remains fixed, while the diameter of the circle can be changed, and thus bulk bags with different aperture sizes can be supported, and the applicability is good.

[0010] Optionally, an installation rack is provided on the workbench, the blower is arranged on the installation rack, a fixing component is provided on the installation rack, the fixing component can fix the bulk bag on the installation rack, and a rotating component is provided on the work rack. The rotating component is connected to the moving gear and is used to drive the moving gear to rotate itself.

[0011] By adopting the above technical solution, when the bulk bag is sleeved on the positioning rod and supported by the positioning rod, the fixing component is enabled, so that the fixing component is connected to the bulk bag, thereby fixing the installation rack and the bulk bag together. At this time, the rotating component is started to drive the moving component to rotate, that is, the positioning rod slides along the circumference direction of the bulk bag on the inner wall of the bulk bag, so as to realize the scraping of the inner wall of the bulk bag and complete the cleaning of the inner wall of the bulk bag.

[0012] Optionally, the fixing component includes a mounting plate and two mounting rods. The mounting plate is arranged on the mounting frame, the mounting rods are slidably connected to the mounting plate, the two mounting rods are symmetrically arranged with respect to the central axis of the moving gear, a driving component is arranged on the mounting plate, and the driving component is connected to the mounting rods for driving the two mounting rods to approach or move away from each other; Two clamping plates are arranged on the mounting rod. One of the clamping plates is fixed on the mounting block, and a bolt is fixed on the other clamping plate. The bolt passes through the mounting rod and is threadedly connected to the mounting rod. When the bolt rotates, the two clamping plates can approach or move away from each other.

[0013] By adopting the above technical solution, when the positioning rod supports the bulk bag, the mounting rod is located in the bulk bag. At this time, the driving component is started to drive the two mounting rods to move away from each other until the mounting rods reach the edge of the bulk bag. Then, the edge of the bulk bag is inserted between the two clamping plates. Subsequently, the bolt is rotated to drive one clamping plate to approach the other clamping plate until the bulk bag is clamped between the two clamping plates, realizing the fixation of the bulk bag and the clamping plate.

[0014] At this time, when the positioning rod moves, the bulk bag will not rotate with it, realizing the scraping of the inner wall of the bulk bag by the positioning rod. The clamping position of the clamping plate needs to be staggered from the positioning rod so that the positioning rod has a moving margin.

[0015] Optionally, the driving component includes a rotating rod. The rotating rod is inserted into the mounting plate, and the end of the rotating rod is rotatably connected to the mounting plate. Threaded structures with opposite rotation directions are arranged at both ends of the rotating rod. The two mounting rods are respectively sleeved at both ends of the rotating rod, and the mounting rod is threadedly connected to the rotating rod. The rotation of the rotating rod is used to drive the two mounting rods to approach or move away from each other.

[0016] By adopting the above technical solution, the rotating rod is driven to rotate self, driving the two mounting rods to approach or move away from each other, so that the two mounting rods are always symmetrically arranged with respect to the central axis of the moving gear. When the mounting rod drives the clamping plate to reach the edge of the bulk bag, the clamping plate is always located on a circular track with the center of the moving gear as the center, so that the clamping plate realizes the positioning and fixation of the bulk bag.

[0017] Optionally, the rotating component includes a rotating motor and a rotating ring. The rotating motor is arranged on the working frame, the output end of the rotating motor is connected to the rotating ring for driving the rotating ring to rotate self, the rotating ring is rotatably connected to the working frame, and the moving component is arranged on the rotating ring.

[0018] By adopting the above technical solution, the rotating motor is started to drive the rotating ring to rotate, thereby driving the entire moving component to rotate, realizing the circular motion of several positioning rods.

[0019] Optionally, a pushing component is provided on the workbench. The pushing component includes a pushing cylinder and a pushing block. The pushing cylinder is arranged on the workbench, and the pushing cylinder is located on the side of the workbench frame away from the mounting frame. The pushing block is connected to the output end of the pushing cylinder.

[0020] By adopting the above technical solution, after the flexible intermediate bulk container (FIBC) is sleeved on the positioning rod, the pushing cylinder is started to drive the pushing block to abut against the end of the FIBC, and move the end of the FIBC towards the opening of the FIBC until the end of the FIBC extends out of the opening of the FIBC, so that the inner wall of the FIBC is turned outwards, that is, the inner wall of the FIBC is exposed, thus enabling a thorough and intuitive cleaning of the FIBC.

[0021] Optionally, a sliding cylinder is provided on the mounting frame. The sliding cylinder is connected to the mounting plate and is used to drive the mounting plate to move towards or away from the pushing component.

[0022] By adopting the above technical solution, when the pushing block drives the end of the FIBC to move towards the opening of the FIBC, the sliding cylinder is started to make the clamping plate on the mounting block clamp the edge of the FIBC and move towards the direction of the pushing cylinder, that is, to make the opening of the FIBC move synchronously towards the end of the FIBC, so that within the stroke of the length of the FIBC, the end of the FIBC meets the opening of the FIBC, thus realizing the inversion of the FIBC faster. During this process, the FIBC takes the end of the positioning rod as the corner point and gradually folds until most of the inside of the FIBC is turned over, and finally part of the edge of the FIBC still wraps around the positioning rod.

[0023] Optionally, a screw rod is inserted into the positioning rod. The screw rod extends out of the top end of the positioning rod, and the screw rod is in threaded connection with the positioning rod.

[0024] By adopting the above technical solution, the screw rod is rotated to adjust the length of the screw rod extending out of the positioning rod, so that the cross bar composed of the positioning rod and the screw rod can be adaptively inserted into FIBCs with different depths to meet the support requirements for FIBCs with different depths, and when the pushing block pushes the end of the FIBC to move, the FIBC has a force application point for internal and external inversion.

[0025] Optionally, a protective pad is sleeved on the positioning rod.

[0026] By adopting the above technical solution, when the positioning rod slides on the inner wall of the FIBC, the protective pad plays a protective role, making the positioning rod not easily wear the FIBC.

[0027] Optionally, a protective ball is fixed at the top end of the screw rod.

[0028] By adopting the above technical solution, when the pushing component pushes the flexible intermediate bulk container (FIBC) to turn inside out, the FIBC bends at the top end of the screw rod. The arc-shaped surface of the protective ball can also play a guiding role, facilitating the bending of the FIBC. At the same time, since the top end of the screw rod is the stress point, the protective ball plays a protective role, making it difficult for the FIBC to be damaged due to stress.

[0029] In summary, the present application includes at least one of the following beneficial effects: 1. During use, the FIBC is sleeved on a plurality of positioning rods. Then, the moving gear is driven to rotate. Since the moving gear meshes with the transmission gear, a plurality of transmission gears rotate synchronously, so as to drive a plurality of positioning racks to drive the positioning rods to move the same distance along the diameter direction of the moving gear at the same time, that is, a plurality of positioning rods gather or disperse at the same time, enabling the plurality of positioning rods to abut against the inner wall of containers with different aperture sizes to support the FIBC, and having good applicability; 2. After the FIBC is sleeved on the positioning rods, the pushing cylinder is started to drive the pushing block to abut against the end of the FIBC, and the end of the FIBC is moved towards the opening of the FIBC until the end of the FIBC extends out of the opening of the FIBC, so that the FIBC turns inside out, that is, the inner wall of the FIBC is exposed, thereby enabling the FIBC to be visually and thoroughly cleaned.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0032] The following will Figures 1-3 further describe the present application in detail.

[0033] The embodiment of the present application discloses a FIBC internal cleaning device. Refer to Figure 1 and Figure 2, The container bag internal cleaning device includes a workbench 10, a work rack 11 and a mounting rack 12. The work rack 11 and the mounting rack 12 are both fixed on the workbench 10. A blower 50 is installed on the mounting rack 12 through bolts 64, and the output end of the blower 50 faces the work rack 11. A rotating assembly 20 is provided on the work rack 11. The rotating assembly 20 is connected to a moving assembly 30. A number of positioning rods 40 are arranged on the moving assembly 30. The number of positioning rods 40 forms a circle, and the container bag can be sleeved on the number of positioning rods 40, so that the opening of the container bag faces the blower 50, so that when the blower 50 is started, the container bag can be blown up.

[0034] Refer to Figure 1 and Figure 2 , where a dust-proof cover 13 is also fixed on the workbench 10. The work rack 11 and the mounting rack 12 are both located inside the dust-proof cover 13, so that when the blower 50 blows off the impurities in the container bag, the impurities are all located inside the dust-proof cover 13, improving the cleanliness of the on-site environment and preventing on-site operators from inhaling too many impurities.

[0035] Refer to Figure 2 and Figure 3 , where the rotating assembly 20 includes a rotating motor 21 and a rotating ring 22. The rotating motor 21 is arranged on the work rack 11, and the output end of the rotating motor 21 is connected to the rotating ring 22 for driving the rotating ring 22 to rotate self. The rotating ring 22 is rotatably connected to the work rack 11, and the moving assembly 30 is arranged on the rotating ring 22.

[0036] Refer to Figure 2 and Figure 3 , the moving assembly 30 includes a moving gear 32 and a number of transmission gears 33. The moving gear 32 is rotatably connected to the rotating ring 22. A rotating gear 31 is rotatably connected to the rotating ring 22. The rotating gear 31 meshes with the moving gear 32. The rotating gear 31 is driven by a motor, and the motor is installed on the rotating ring 22 through bolts 64. When the rotating gear 31 rotates, it is used to drive the moving gear 32 to rotate self. The transmission gears 33 are also rotatably connected to the rotating ring 22. The number of transmission gears 33 is arranged at intervals along the circumference of the moving gear 32, and the transmission gears 33 mesh with the moving gear 32. A number of positioning racks 34 are slidably connected to the work rack 11. The number of positioning racks 34 corresponds to the transmission gears 33 one by one, and the positioning racks 34 mesh with the corresponding transmission gears 33.

[0037] Refer to Figure 2 and Figure 3, a number of positioning racks 34 are arranged radially with the center of the moving gear 32 as the center of the circle. The number of positioning racks 34 corresponds to the positioning rods 40 one by one. The positioning rods 40 are arranged horizontally, and one end of the positioning rod 40 is fixed to the positioning rack 34. During use, the flexible intermediate bulk container (FIBC) is sleeved on a number of positioning rods 40, and then the moving gear 32 is driven to rotate. Since the moving gear 32 meshes with the transmission gears 33, a number of transmission gears 33 are synchronously rotated, so as to drive a number of positioning racks 34 to drive the positioning rods 40 to move the same distance along the diameter direction of the moving gear 32 at the same time, that is, a number of positioning rods 40 are gathered or spread at the same time until a number of positioning rods 40 simultaneously abut against the inner wall of the FIBC, realizing the support for the FIBC. Among them, a number of positioning rods 40 can be gathered or spread at the same time, so that the center of the circle formed by a number of positioning rods 40 remains fixed, while the diameter of the circle can be changed, and thus FIBCs with different aperture sizes can be supported, and the applicability is good.

[0038] Referring to Figure 2 and Figure 3 , in order to increase the stability of the FIBC sleeved on the positioning rod 40, a fixing component 60 is provided on the mounting frame 12. The fixing component 60 includes a mounting plate 61 and two mounting rods 62. The mounting plate 61 is arranged on the mounting frame 12 through a sliding cylinder 611. The sliding cylinder 611 can drive the mounting plate 61 to move in a direction close to or away from the working frame 11. The mounting rod 62 is slidably connected to the mounting plate 61. The two mounting rods 62 are arranged symmetrically with the central axis of the moving gear 32 as the axis of symmetry. A driving component 70 is provided on the mounting plate 61. The driving component 70 includes a rotating rod 71. The rotating rod 71 is inserted into the mounting plate 61. The end of the rotating rod 71 is rotatably connected to the mounting plate 61. Thread structures with opposite rotation directions are provided at both ends of the rotating rod 71, that is, the rotating rod 71 is a bidirectional lead screw, and one end of the rotating rod 71 is driven by a motor. The two mounting rods 62 are respectively sleeved on both ends of the rotating rod 71, and the mounting rod 62 is threadedly connected to the rotating rod 71.

[0039] Referring to Figure 2 and Figure 3 , two clamping plates 63 are provided on the mounting rod 62. One of the clamping plates 63 is fixed to the mounting block, and a bolt 64 is fixed to the other clamping plate 63. The bolt 64 passes through the mounting rod 62 and is threadedly connected to the mounting rod 62. When the positioning rod 40 supports the flexible intermediate bulk container (FIBC), the mounting rod 62 passes through the rotating ring 22, that is, the top of the mounting rod 62 is located inside the FIBC. At this time, the rotating rod 71 is driven to rotate self - sufficiently, and the two mounting rods 62 are driven to move away from each other, so that the two mounting rods 62 are always arranged symmetrically with respect to the central axis of the moving gear 32. When the mounting rod 62 drives the clamping plate 63 to reach the edge of the FIBC, the edge of the FIBC is inserted between the two clamping plates 63. Subsequently, the bolt 64 is rotated to drive one of the clamping plates 63 to approach the other clamping plate 63 until the FIBC is clamped between the two clamping plates 63, realizing the fixation of the FIBC and the clamping plate 63. The clamping position of the clamping plate 63 needs to be staggered from the positioning rod 40, so that the positioning rod 40 has a margin for movement.

[0040] When the sliding cylinder 611 drives the mounting rod 62 to gradually penetrate into the FIBC, the clamping plate 63 clamping the edge of the FIBC gradually disengages from the positioning rod 40, facilitating the removal of the FIBC from the positioning rod 40.

[0041] After the clamping plate 63 clamps the FIBC, the rotating motor 21 is started to drive the rotating ring 22 to rotate, thereby driving the entire moving assembly 30 to rotate, realizing that several positioning rods 40 make circular motions, that is, the positioning rods 40 slide along the circumferential direction of the FIBC on the inner wall of the FIBC, thereby realizing the scraping of the inner wall of the FIBC and completing the cleaning of the inner wall of the FIBC.

[0042] Refer to Figure 1 and Figure 2 As shown in FIGS. and, a pushing assembly 80 is provided on the workbench 10. The pushing assembly 80 includes a pushing cylinder and a pushing block 82. The pushing cylinder is installed on the workbench 10 through bolts 64, and the pushing cylinder is located on the side of the workbench 11 away from the mounting frame 12. The pushing block 82 is connected to the output end of the pushing cylinder.

[0043] After the FIBC is sleeved on the positioning rod 40, the pushing cylinder is started to drive the pushing block 82 to abut against the end of the FIBC and move the end of the FIBC towards the opening of the FIBC. During this process, the sliding cylinder 611 is started to make the clamping plate 63 on the mounting block clamp the edge of the FIBC and move towards the direction of the pushing cylinder, that is, to make the opening of the FIBC move synchronously towards the end of the FIBC, so that the end of the FIBC meets the opening of the FIBC faster and extends out from the opening of the FIBC, turning the FIBC inside out, that is, the inner wall of the FIBC is exposed, so that the FIBC can be visually and thoroughly cleaned.

[0044] During the process of turning the FIBC inside out, the FIBC takes the end of the positioning rod 40 as the corner point and gradually folds until most of the inside of the FIBC is turned over, and finally there is still a part of the edge of the FIBC wrapping the positioning rod 40.

[0045] Refer to Figure 3, in order to enable the positioning rod 40 to support the flexible intermediate bulk containers (FIBCs) at different depths, a screw rod 42 is inserted into the positioning rod 40. The screw rod 42 extends out of the top end of the positioning rod 40, and the screw rod 42 is threadedly connected to the positioning rod 40. A protective ball 421 is fixed to the top end of the screw rod 42. A protective pad 411 is sleeved on the positioning rod 40, so that the positioning rod 40 is not likely to damage the FIBC when scraping the inner wall of the FIBC.

[0046] Rotate the screw rod 42 to adjust the length of the screw rod 42 extending out of the positioning rod 40, so that the cross bar formed by the positioning rod 40 and the screw rod 42 can be adaptively inserted into FIBCs at different depths to meet the support for FIBCs at different depths, so that when the pushing block 82 pushes the end of the FIBC to move, the FIBC has a force application point for internal and external turning.

[0047] When the pushing assembly 80 pushes the FIBC to turn inside out, the FIBC bends at the top end of the screw rod 42, and the arc-shaped surface of the protective ball 421 can also play a guiding role to facilitate the bending of the FIBC. At the same time, since the top end of the screw rod 42 is the force application point, the protective ball 421 plays a protective role, so that the FIBC is not likely to be damaged due to force.

[0048] The implementation principle of an internal cleaning device for FIBCs in an embodiment of the present application is as follows: The FIBC is sleeved on the positioning rod 40. At the same time, the blower 50 is started to make the FIBC in an inflated state, which is convenient for the positioning rod 40 to be inserted. Thereafter, the moving gear 32 drives the positioning rack 34 and the positioning rod 40 to move through the transmission gear 33, so that the positioning rod 40 can tightly support the FIBC. Then, the clamping plate 63 of the fixing assembly 60 clamps the opening part of the FIBC. The distance between the two mounting rods 62 is adjusted by the rotating rod 71 of the driving assembly 70 to ensure that the FIBC is firmly fixed. Subsequently, the pushing cylinder drives the pushing block 82 to push the end of the FIBC out of the opening of the FIBC, so that the FIBC turns inside out, which is convenient for thorough cleaning of the inside of the FIBC.

[0049] The above are all the preferred embodiments of the present application. The protection scope of the present application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape and principle of the present application should be covered within the protection scope of the present application.
