Description

Technical Field

[0001] This invention relates to the field of rolling mill maintenance technology, and in particular to a device for cleaning the trench of an aluminum foil rolling mill. Background Technology

[0002] Aluminum foil is a material that is rolled into thin sheets using a direct rolling mill for metallic aluminum. It is soft, has good ductility, and has a silvery-white luster.

[0003] However, during the aluminum foil rolling process, aluminum foil debris inevitably falls into the rolling mill trench. If not cleaned for a long time, this will affect the surrounding environment, cause problems for equipment maintenance, and in severe cases, even affect production. Because vertical pipes are installed on both sides of the rolling mill trench, automated cleaning equipment cannot completely clean the aluminum foil debris from the trench. Therefore, the current practice is still for personnel to crawl into the trench under the equipment to clean it, which is not only slow but also labor-intensive.

[0004] To address this, we designed a cleaning device for the trench of an aluminum foil rolling mill. Summary of the Invention

[0005] In order to overcome the shortcomings of the prior art, the present invention discloses an aluminum foil rolling mill trench cleaning device.

[0006] To achieve the above-mentioned objectives, the present invention adopts the following technical solution: A cleaning device for an aluminum foil rolling mill trench includes a suction body, and a suction assembly is connected to one side of the suction body; The suction assembly includes a fixed suction tube with a suction inlet located slightly below the front of the tube body. Both ends of the fixed suction tube are axially slidably connected to movable suction tubes with suction inlets located slightly below the front of the tube body. A fixed rod extending forward is provided in the middle of the fixed suction tube. A telescopic rod is hinged between the outer end of the movable suction tube and the front end of the fixed rod, so that when the telescopic rod touches the vertical pipe in the rolling mill trench, it causes the telescopic rod to rotate inward, thereby causing the telescopic rod and the movable suction tube to retract. A compression spring is provided between the telescopic rod and the fixed rod, so that the telescopic rod rotates outward, causing the movable suction tube and the telescopic rod to extend.

[0007] Preferably, the inlet is flattened along the axial direction of the corresponding inlet tube.

[0008] Preferably, the portion of the inlet of the movable inhalation tube located within the inner cavity of the fixed inhalation tube coincides with the inlet of the fixed inhalation tube.

[0009] Preferably, the inhalation body includes a main body box, the main body box having a main body cavity corresponding to and communicating with the inhalation component, and the bottom of the side wall of the main body cavity having an openable and closable door; a negative pressure pump communicating with the upper part of the main body cavity through a filter screen is provided on one side of the main body cavity; and a compaction member that can move up and down is provided in the upper part of the main body cavity to compact the aluminum foil inhaled into the main body cavity.

[0010] Preferably, the inhalation body further includes a drive structure for driving the compaction member to move up and down.

[0011] Preferably, the compaction component includes a movable block, and the bottom of the movable block is connected to a compaction plate that matches the main cavity via an elastic element.

[0012] Preferably, the bottom of the main body box is provided with wheels.

[0013] Preferably, the drive structure includes a first reversing gearbox correspondingly connected to the wheel axle and a vertical rack slidably connected to the main body box. The output shaft of the first reversing gearbox is provided with a second reversing gearbox. The output shaft of the second reversing gearbox is fixedly sleeved with a half-tooth gear that can mesh with the vertical rack, so as to intermittently drive the vertical rack to rise. The top of the compactor has an extension that extends above the vertical rack.

[0014] Preferably, the main body cavity has a transmission cavity on the side corresponding to the wheel for accommodating the drive structure.

[0015] By employing the technical solution described above, the present invention has the following beneficial effects: 1. After the telescopic rod touches the vertical pipe in the mill trench, it causes the telescopic rod to rotate inward, which in turn causes the telescopic rod and the movable suction pipe to retract, reducing the overall length of the fixed suction pipe and the movable suction pipe so that they can pass through the gap between the vertical pipes on both sides of the mill trench; then, under the action of the compression spring, the telescopic rod rotates outward, causing the movable suction pipe and the telescopic rod to extend, so that the movable suction pipe is in the extended state, allowing the suction assembly to adaptively change its length according to the position of the vertical pipe in the mill trench for operation; 2. The drive structure is designed to drive the first and second gearboxes through the rotation of the wheels, which in turn drives the half-tooth gear to rotate. When the half-tooth gear meshes with the vertical rack, it drives the vertical rack to rise, which in turn drives the compaction component to rise. When the half-tooth gear disengages from the vertical rack, the vertical rack and the compaction component accelerate downward under the action of gravity. At this time, the compaction component squeezes the aluminum foil in the main cavity, increasing the amount of aluminum foil that the main cavity can hold. 3. The design of the drive structure and compaction components allows the compaction components to repeatedly rise and fall under the action of the drive structure and gravity. During this process, the compaction plate repeatedly scrapes the aluminum foil off the filter screen, ensuring the normal operation of the negative pressure pump. Attached Figure Description

[0018] The present invention will be explained in detail through the following embodiments. The purpose of disclosing the present invention is to protect all technical improvements within the scope of the present invention. In the description of the present invention, it should be understood that if terms such as "upper", "lower", "front", "rear", "left", "right" indicate orientation or positional relationship, they are only corresponding to the drawings of this application for the purpose of describing the present invention. It should be understood that if terms such as "end", "side", "end portion", "side part", "lateral", "longitudinal", etc. indicate orientation or positional relationship, they are only corresponding to the length and width of the corresponding component. That is, "end" indicates the head and tail area in the length direction of the corresponding component, and "side part" indicates the head and tail area in the width direction of the corresponding component. The present invention is disclosed for the purpose of describing the present invention and does not indicate or imply that the device or element referred to must have a specific orientation.

[0019] Example 1, in conjunction with Appendix Figure 1-6 A cleaning device for an aluminum foil rolling mill trench includes a suction body 1. If necessary, the bottom of the suction body 1 is provided with wheels 18. Furthermore, the suction body 1 also has a drive device for driving the wheels 18 to rotate.

[0020] The inhalation body 1 is connected to an inhalation component 2 on one side; combined with the attached Figure 5-6 The inhalation assembly 2 includes a fixed inhalation tube 21 with an inhalation port located at the lower front side of the tube body, and a movable inhalation tube 22 with an inhalation port located at the lower front side of the tube body is axially slidably connected to both ends of the fixed inhalation tube 21. As needed, to prevent the movable suction tube 22 from contracting and blocking the suction port of the fixed suction tube 21, the suction port is flattened along the axial direction of the corresponding suction tube; the portion of the suction port of the movable suction tube 22 located in the inner cavity of the fixed suction tube 21 coincides with the suction port of the fixed suction tube 21.

[0021] It should be noted that the inner end of the active suction tube 22 is open, while the outer end is sealed.

[0022] In this example, the length of the fixed suction pipe 21 is set according to the distance between the vertical pipes on both sides of the mill trench. Specifically, the length of the fixed suction pipe 21 is less than the distance between the vertical pipes on both sides of the mill trench, so as to ensure that the fixed suction pipe 21 can move horizontally without obstruction in the mill trench.

[0023] Furthermore, when the two movable suction pipes 22 are in the retracted state, the overall length of the fixed suction pipe 21 and the movable suction pipe 22 is less than the distance between the vertical pipes on both sides in the mill trench.

[0024] The fixed suction tube 21 has a forward-extending fixed rod 23 in the middle of its body. The outer end of the movable suction tube 22 is hinged to the front end of the fixed rod 23, and a compression spring 25 is provided between the telescopic rod 24 and the fixed rod 23.

[0025] Depending on the requirements, telescopic pole 24 can be a multi-section telescopic pole.

[0026] In this example, the fixed part of the telescopic rod 24 is located on one side of the fixed rod 23. That is, the outer end of the fixed part of the telescopic rod 24 is hinged to the front end of the fixed rod 23, and the outer end of the telescopic part of the telescopic rod 24 is hinged to the outer end of the corresponding movable suction tube 22. Furthermore, a compression spring 25 is provided between the fixed part of the telescopic rod 24 and the fixed rod 23.

[0027] This configuration allows the telescopic rod 24 to rotate inward after it touches the vertical pipe in the mill trench, causing the telescopic rod 24 and the movable suction pipe 22 to retract. This reduces the overall length of the fixed suction pipe 21 and the movable suction pipe 22, allowing them to pass through the gap between the vertical pipes on both sides of the mill trench. Then, under the action of the compression spring 25, the telescopic rod 24 rotates outward, causing the movable suction pipe 22 and the telescopic rod 24 to extend. This allows the movable suction pipe 22 to be in an extended state, enabling the suction assembly 2 to adaptively change its length according to the position of the vertical pipe in the mill trench.

[0028] Furthermore, in conjunction with the appendix Figure 2-3 The inhalation unit 1 includes a main body box 11, inside which is a main body cavity 12 corresponding to and communicating with the inhalation assembly 2. The bottom of the side wall of the main body cavity 12 is provided with an openable door 13. A negative pressure pump 15 is provided on one side of the upper section of the main body cavity 12 and communicates with it through a filter screen 14. As needed, the main body box 11 has a power chamber for holding the negative pressure pump 15. The upper section of the main body cavity 12 is provided with a compaction member 16 that can move up and down to facilitate the compaction of the aluminum foil inhaled into the main body cavity 12.

[0029] In one possible implementation, the top of the main cavity 12 may be provided with an openable cover plate, and the compaction of the aluminum foil is completed by manually or using other structural equipment to press the compaction member 16 downward.

[0030] The suction body 1 also includes a drive structure 17 for driving the compaction member 16 to move up and down.

[0031] In one possible implementation, the top of the main cavity 12 may also be provided with a telescopic device, which presses the compacting member 16 downward through the telescopic device to complete the compaction operation of the aluminum foil.

[0032] In one possible implementation, combined with the appendix Figure 3-4 The drive structure 17 includes a first reversing gearbox 171 correspondingly connected to the axle of the wheel 18 and a vertical rack 174 slidably connected to the main body housing 11. The output shaft of the first reversing gearbox 171 is provided with a second reversing gearbox 172. The output shaft of the second reversing gearbox 172 is fixedly fitted with a half-tooth gear 173 that can mesh with the vertical rack 174, so as to intermittently drive the vertical rack 174 to rise. The top of the compaction member 16 has an extension that extends above the vertical rack 174. If necessary, the main body cavity 12 is provided on the side corresponding to the wheel 18 for accommodating the drive structure 17.

[0033] As needed, the output shaft of the first reversing gearbox 171 faces upward to increase the height of the second reversing gearbox 172, thereby increasing the height of the vertical rack 164, so that the vertical rack 164 has room to descend.

[0034] Specifically, the output shaft of the second reversing gearbox 172 is horizontally positioned, and further, the output shaft of the second reversing gearbox 172 is positioned along the moving direction of the suction body 1.

[0035] Furthermore, the first reversing gearbox 171 and the second reversing gearbox 172 can adjust their speed ratio according to actual needs, so that the half-tooth gear 173 reaches a reasonable speed.

[0036] It should be noted that the half-tooth gear 173 can be understood as one half of the gear 173 having teeth, and the other half not having teeth.

[0037] This configuration allows the first reversing gearbox 171 and the second reversing gearbox 172 to rotate via the rotation of the wheel 18, which in turn drives the half-tooth gear 173 to rotate. When the half-tooth gear 173 meshes with the vertical rack 174, the half-tooth gear 173 drives the vertical rack 174 to rise, which in turn drives the compactor 16 to rise. When the half-tooth gear 173 disengages from the vertical rack 174, the vertical rack 174 and the compactor 16 accelerate downward under the action of gravity. At this time, the compactor 16 squeezes the aluminum foil in the main cavity 12, increasing the amount of aluminum foil that the main cavity 12 can hold.

[0038] As needed, the door 13 is located below the connection between the suction assembly 2 and the main body cavity 12 to prevent the compressed aluminum foil from blocking the connection between the suction assembly 2 and the main body cavity 12.

[0039] Example 2, in conjunction with Appendix Figure 3 A cleaning device for an aluminum foil rolling mill trench, based on Embodiment 1, includes a compaction component 16 comprising a movable block 161. The bottom of the movable block 161 is connected to a compaction plate 163 matching the main cavity 12 via an elastic element 162. This arrangement allows the movable block 161 and the compaction plate 163 to move downwards under gravity after the half-tooth gear 173 disengages from the vertical rack 174. When the extension of the movable block 161 is restricted from descending by the vertical rack 174, the compaction plate 163 can pull the elastic element 162 to continue descending a certain distance. After the elastic element 162 resets, the compaction plate 163 rises to a stable height. This allows the compaction plate 163 to scrape the filter screen 14 during its descent to the lowest point, removing the aluminum foil from the filter screen 14 and ensuring that the negative pressure pump 15 can normally draw in gas from the main cavity 12.

It will be apparent to those skilled in the art that this invention is not limited to the details of the above exemplary embodiments, and that the invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be regarded as exemplary and non-limiting in all respects, and are intended to encompass all changes falling within the meaning and scope of equivalents within this invention.
