Description

Technical Field

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

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

[0003] However, during the rolling process, aluminum foil debris will fall into the trench of the rolling mill. If it is not cleaned for a long time, it will affect the environment around the equipment and cause trouble for maintenance equipment. In serious cases, it will affect production. Since vertical pipes are arranged on both sides of the trench of the rolling mill, it is difficult for automated cleaning equipment to complete the operation of fully cleaning the aluminum foil debris in the trench. As a result, the current practice is still: personnel drill into the trench under the equipment to clean it, which is not only slow but also labor-intensive.

[0004] Therefore, we designed a trench cleaning device for an aluminum foil rolling mill. Summary of the invention

[0005] In order to overcome the deficiencies in the background technology, the present invention discloses a trench cleaning device for an aluminum foil rolling mill.

[0006] In order to achieve the above-mentioned invention object, the present invention adopts the following technical scheme: An aluminum foil rolling mill trench cleaning device comprises a suction body, one side of which is connected to a suction assembly; The suction assembly includes a fixed suction pipe with a suction port at a lower front side of the pipe body, and both ends of the fixed suction pipe are axially slidably connected to a movable suction pipe with a suction port at a lower front side of the pipe body; a fixed rod extending forward is provided in the middle of the fixed suction pipe body, and a telescopic rod is hinged between the outer end of the movable suction pipe and the front end of the fixed rod, so that after the telescopic rod touches the vertical pipe in the rolling mill trench, the telescopic rod is prompted to rotate inward, thereby causing the telescopic rod and the movable suction pipe to retract; a compression spring is provided between the telescopic rod and the fixed rod, so that the telescopic rod is rotated outward, causing the movable suction pipe and the telescopic rod to extend.

[0007] Preferably, the suction port is flat and arranged along the axial direction of the corresponding suction pipe.

[0008] Preferably, the part of the suction port of the movable suction pipe located in the inner cavity of the fixed suction pipe coincides with the suction port of the fixed suction pipe.

[0009] Preferably, the suction body includes a main body box, the interior of the main body box has a main body cavity corresponding to the suction component, and the bottom of the side wall of the main body cavity is provided with a door that can be opened and closed; one side of the upper section of the main body cavity is provided with a negative pressure pump connected to the main body cavity through a filter; the upper section of the main body cavity is provided with a compacting piece that can move up and down to facilitate the compaction of the aluminum foil sucked into the main body cavity.

[0010] Preferably, the suction body further comprises a driving structure for driving the compacting member to move up and down.

[0011] Preferably, the compacting member comprises a movable block, and the bottom of the movable block is connected to a compacting plate matching the main body cavity via an elastic member.

[0012] Preferably, wheels are provided at the bottom of the main box.

[0013] Preferably, the driving structure comprises a first direction-changing gearbox correspondingly connected to the wheel axle and a vertical rack connected to the main body box in an up-and-down sliding manner, the output shaft of the first direction-changing gearbox is provided with a second direction-changing gearbox, and the fixed sleeve of the output shaft of the second direction-changing gearbox is provided with a half-toothed gear that can mesh with the vertical rack, so as to intermittently drive the vertical rack to rise; The top of the compacting member has an extension portion extending above the vertical rack.

[0014] Preferably, a transmission cavity for accommodating a driving structure is provided on a side of the main body cavity corresponding to the wheel.

[0015] Due to the adoption of the above-mentioned technical solution, the present invention has the following beneficial effects: 1. After the telescopic rod touches the vertical pipe in the mill trench, the telescopic rod is caused to rotate inward, thereby causing the telescopic rod and the movable suction pipe to contract, so that the overall length of the fixed suction pipe and the movable suction pipe becomes smaller and passes 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 an extended state, so that the suction assembly can adaptively change the length according to the position of the vertical pipe in the mill trench to operate; 2. The setting of the driving structure can drive the first and second direction-changing gear boxes to operate through the rotation of the wheel, and then drive the half-toothed gear to rotate. When the half-toothed gear is engaged with the vertical rack, the half-toothed gear drives the vertical rack to rise, and then drives the compacting member to rise. When the half-toothed gear is out of engagement with the vertical rack, the vertical rack and the compacting member are accelerated to descend under the action of gravity. At this time, the compacting member squeezes the aluminum foil in the main cavity, increasing the capacity of the main cavity to hold the aluminum foil; 3. The arrangement of the driving structure and the compacting piece can make the compacting piece repeatedly move up and down under the action of the driving structure and gravity, and in this process, the compacting plate repeatedly scrapes off the aluminum foil on the filter screen to ensure the normal operation of the negative pressure pump.

[0019] Embodiment 1, in combination with the attached Figure 1-6 A ditch cleaning device for an aluminum foil rolling mill includes a suction body 1. As required, a wheel 18 is provided at the bottom of the suction body 1. Furthermore, the suction body 1 also has a driving device for driving the wheel 18 to rotate.

[0020] One side of the suction body 1 is connected to the suction assembly 2; Figure 5-6 The suction assembly 2 includes a fixed suction pipe 21 having a suction port at a lower front side of the pipe body, and both ends of the fixed suction pipe 21 are axially slidably connected to a movable suction pipe 22 having a suction port at a lower front side of the pipe body; As needed, in order to prevent the movable suction pipe 22 from shrinking and blocking the suction port of the fixed suction pipe 21, the suction port is flatly arranged along the axial direction of the corresponding suction pipe; the suction port of the movable suction pipe 22 is located in the inner cavity of the fixed suction pipe 21 and overlaps with the suction port of the fixed suction pipe 21.

[0021] It should be noted that the inner end of the movable suction pipe 22 is in an open state, and the outer end is in a blocked state.

[0022] In the example, the length of the fixed suction pipe 21 is set according to the spacing between the vertical pipes on both sides of the rolling mill trench. Specifically, the length of the fixed suction pipe 21 is smaller than the spacing between the vertical pipes on both sides of the rolling mill trench, ensuring that the fixed suction pipe 21 can move horizontally without obstacles in the rolling mill trench.

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

[0024] A fixed rod 23 extending forward is provided in the middle of the fixed suction pipe 21 , a telescopic rod 24 is hinged between the outer end of the movable suction pipe 22 and 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] As required, the telescopic rod 24 is a multi-section telescopic rod.

[0026] In the example, the fixed portion of the telescopic rod 24 is correspondingly located on one side of the fixed rod 23, that is, the outer end of the fixed portion of the telescopic rod 24 is correspondingly hinged to the front end of the fixed rod 23, and the outer end of the telescopic portion of the telescopic rod 24 is correspondingly hinged to the outer end of the corresponding movable suction pipe 22. Further, a compression spring 25 is provided between the fixed portion of the telescopic rod 24 and the fixed rod 23.

[0027] With this arrangement, after the telescopic rod 24 touches the vertical pipe in the mill trench, the telescopic rod 24 is prompted to rotate inward, thereby causing the telescopic rod 24 and the movable suction pipe 22 to contract, so that the overall length of the fixed suction pipe 21 and the movable suction pipe 22 is reduced and passes 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, so that the movable suction pipe 22 is in an extended state, so that the suction assembly 2 can adaptively change the length according to the position of the vertical pipe in the mill trench to operate.

[0028] Furthermore, combined with Figure 2-3 The suction body 1 includes a main body box 11, which has a main body cavity 12 corresponding to the suction assembly 2, and a door 13 that can be opened and closed is provided at the bottom of the side wall of the main body cavity 12; a negative pressure pump 15 connected to the main body cavity 12 through a filter 14 is provided on one side of the upper section of the main body cavity 12; and a power chamber for containing the negative pressure pump 15 is provided in the main body box 11 as needed. A compacting member 16 that can move up and down is provided on the upper section of the main body cavity 12 to compact the aluminum foil sucked into the main body cavity 12.

[0029] In a possible implementation, a cover plate that can be opened and closed may be provided on the top of the main cavity 12, and the compacting member 16 is pressed downward manually or by other structural equipment to complete the compaction operation of the aluminum foil.

[0030] The suction body 1 further comprises a driving structure 17 for driving the compacting member 16 to move up and down.

[0031] In a possible implementation, a telescopic device may be further provided on the top of the main cavity 12, and the compacting member 16 is pressed downward by the telescopic device to complete the compaction operation of the aluminum foil.

[0032] In a possible implementation, Figure 3-4 The driving structure 17 includes a first direction-changing gearbox 171 corresponding to the wheel axle 18 and a vertical rack 174 slidably connected to the main body box 11. The output shaft of the first direction-changing gearbox 171 is provided with a second direction-changing gearbox 172. The fixed sleeve of the output shaft of the second direction-changing gearbox 172 is provided with a half-tooth gear 173 that can mesh with the vertical rack 174, so as to intermittently drive the vertical rack 164 to rise; the top of the compacting member 16 has an extension extending to the top of the vertical rack 174. As needed, a transmission chamber 19 for accommodating the driving structure 17 is provided on one side of the main body cavity 12 corresponding to the wheel 18.

[0033] As required, the output shaft of the first direction-changing gear box 171 faces upward, so as to increase the height of the second direction-changing gear box 172 , thereby increasing the height of the vertical rack 164 , so that the vertical rack 164 has space to descend.

[0034] Specifically, the output shaft of the second direction changing gear box 172 is arranged horizontally. Further, the output shaft of the second direction changing gear box 172 is arranged along the moving direction of the suction body 1.

[0035] Furthermore, the first direction changing gear box 171 and the second direction changing gear box 172 can adjust their speed ratios according to actual needs, so that the half-toothed gear 173 reaches a reasonable speed.

[0036] It should be noted that the half-toothed gear 173 can be understood as a gear 173 having teeth on half of its circumference and no teeth on the other half.

[0037] Such an arrangement can drive the first and second direction-changing gear boxes 171 and 172 to operate through the rotation of the wheel 18, and then drive the half-tooth gear 173 to rotate. When the half-tooth gear 173 is engaged with the vertical rack 174, the half-tooth gear 173 drives the vertical rack 174 to rise, and then drives the compacting member 16 to rise. When the half-tooth gear 173 is disengaged from the vertical rack 174, the vertical rack 174 and the compacting member 16 are accelerated to descend under the action of gravity. At this time, the compacting member 16 squeezes the aluminum foil in the main cavity 12, thereby increasing the amount of aluminum foil that can be held in the main cavity 12.

[0038] As required, the door 13 is located below the connection between the suction component 2 and the main cavity 12 to prevent the compacted aluminum foil from blocking the connection between the suction component 2 and the main cavity 12 .

[0039] Embodiment 2, combined with the attached Figure 3 , a ditch cleaning device for an aluminum foil rolling mill, based on the first embodiment, the compacting member 16 includes a movable block 161, and the bottom of the movable block 161 is connected to a compacting plate 163 matching the main cavity 12 through an elastic member 162; such a configuration enables the movable block 161 and the compacting plate 163 to move downward under the action of gravity after the half-tooth gear 173 disengages from the vertical rack 174, and when the extended portion of the movable block 161 is restricted by the vertical rack 174 and cannot descend, the compacting plate 163 can pull the elastic member 162 to continue to descend for a distance, and then after the elastic member 162 is reset, the compacting plate 163 is raised to a stable height, and then the compacting plate 163 can be made to stabilize the height of the compacting plate 163 and to perform a scraping action on the filter screen 14 during the process of the compacting plate 163 descending to the lowest point, scraping off the aluminum foil on the filter screen 14, and ensuring that the negative pressure pump 15 normally inhales the gas in the main cavity 12.

[0040] The parts of the present invention that are not described in detail are prior art. It is obvious to those skilled in the art that the present invention is not limited to the details of the above-mentioned exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention; therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and it is intended that all changes that fall within the meaning and scope of equivalent elements are included in the present invention.
