Description

Technical Field

[0001] This utility model relates to the field of aluminum alloy production and processing technology, specifically to a continuous casting machine for aluminum alloy plates. Background Technology

[0002] Continuous casting machines play a crucial role in the production of aluminum alloy sheets. The conveyor rollers of the continuous casting machine are responsible for continuously casting molten aluminum alloy into sheets and transporting them; their working condition directly affects the quality of the sheets and production efficiency. However, during the transport process, impurities, oxides, and deposits generated during cooling in the molten aluminum alloy continuously adhere to the surface of the conveyor rollers.

[0003] If these deposits are not removed in time, they will increase the surface roughness of the conveyor rollers, causing scratches and abrasions on the surface of the aluminum alloy sheets during the conveying process, which will seriously affect the surface quality of the sheets. On the other hand, the uneven distribution of the deposits will disrupt the dynamic balance of the conveyor rollers, causing vibration during the conveying process. This will not only reduce the conveying accuracy, but also accelerate the wear of the conveyor rollers and related equipment, increase equipment maintenance costs, and may even cause equipment failure, affecting the continuity of production.

[0004] Currently, common methods for cleaning the conveyor rollers of continuous casting machines include manual periodic cleaning and the use of simple mechanical scraping devices. Manual cleaning requires operators to manually scrape off the deposits on the surface of the conveyor rollers while the equipment is stopped. This method is labor-intensive, inefficient, and due to the limitations of manual operation, it is difficult to guarantee thorough and uniform cleaning. While simple mechanical scraping devices can achieve a certain degree of automation, they can easily damage the surface of the conveyor rollers, shortening their service life, and are ineffective at cleaning some strongly adhesive impurities and fine deposits. Therefore, developing a self-cleaning device that can automatically, efficiently, and non-destructively clean the conveyor rollers of continuous casting machines is of significant practical importance. Utility Model Content

[0005] To address the aforementioned problems, this invention provides a continuous casting machine for aluminum alloy plates.

[0006] To achieve the above-mentioned technical objectives and effects, this utility model is implemented through the following technical solution:

[0007] A continuous casting machine for aluminum alloy sheets includes a base. Fixed seats are provided on both the front and rear sides of the bottom wall of the base. A motor is provided on the front side of the inner bottom wall of the base. The output end of the motor is locked with a lead screw via a coupling, and the rear end of the lead screw is rotatably connected to the inner wall of the base via a bearing. A connecting block is threaded onto the outer wall of the lead screw. A connecting rod is provided on the top wall of the connecting block. The top wall of the connecting rod extends beyond the base and is provided with a connecting plate. A gearbox is provided on the left side of the top wall of the connecting plate. The input and output ends of the gearbox are respectively provided with a main shaft and a driven shaft. A second motor is provided on the right side of the top wall of the connecting plate, and the output end of the second motor is fixedly connected to the right side end of the main shaft via a coupling. A lifting and cleaning mechanism is provided on the top wall of the driven shaft.

[0008] Furthermore, the lifting cleaning mechanism includes a top plate, with an inlet pipe on the right side of the top wall of the top plate, a hydraulic telescopic rod on the left side of the top wall of the top plate, and a cleaning mechanism on the driving bottom wall of the hydraulic telescopic rod.

[0009] Furthermore, the cleaning mechanism includes a rectangular plate, a connecting pipe is provided between the top wall of the rectangular plate and the top plate, an arc-shaped plate is provided on the bottom wall of the rectangular plate through a connecting seat, a plurality of nozzles are provided in the middle of the inner top wall of the arc-shaped plate, and brushes are provided on both the front and rear sides of the inner top wall of the arc-shaped plate.

[0010] Furthermore, multiple nozzles are arranged between the brushes from left to right with spacing.

[0011] Furthermore, the inlet pipe, top plate, connecting pipe, rectangular plate, connecting seat, arc plate, and nozzle are interconnected.

[0012] Furthermore, a counterweight is provided on the right side of the top wall of the top plate.

[0013] The beneficial effects of this utility model are:

[0014] This self-cleaning device can quickly adjust the position of the nozzle and brush to be directly above the conveyor roller through the cooperation of the motor and the lead screw. When the conveyor roller rotates, the nozzle sprays cleaning liquid to soften impurities, and the brush simultaneously brushes them. It can achieve online real-time cleaning without stopping the equipment, which greatly improves cleaning efficiency. Compared with manual cleaning, it can complete large-area cleaning work in a short time and ensure efficient and continuous production.

[0015] This device uses a combination of cleaning fluid softening and brush cleaning. The brush is soft and will not cause hard scratches on the surface of the conveyor roller during the cleaning process, thus extending the service life of the conveyor roller, reducing maintenance costs caused by equipment wear, reducing the probability of equipment failure, and ensuring stable production operation.

[0016] The operation of adjusting the position of motor one, controlling the up and down movement of the nozzle and brush with the hydraulic telescopic rod, and moving the cleaning structure away from the conveyor line with motor two are all completed automatically by the device without much human intervention. This reduces the labor intensity of operators, minimizes the limitations of manual operation, and ensures the stability and consistency of cleaning work.

[0017] Timely and thorough cleaning of the conveyor rollers prevents defects such as scratches and abrasions on aluminum alloy sheets caused by increased surface roughness and disruption of dynamic balance. This improves the surface quality and conveying accuracy of the sheets, helps produce high-quality aluminum alloy sheets, and enhances product competitiveness. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0025] See Figure 1-3As shown, a continuous casting machine for aluminum alloy plates includes a base 1. Fixed seats 2 are provided on both the front and rear sides of the bottom wall of the base 1. A motor 3 is provided on the front side of the inner bottom wall of the base 1.

A connecting block 5 is threaded onto the outer wall of the lead screw 4. A connecting rod 6 is provided on the top wall of the connecting block 5. The top wall of the connecting rod 6 extends beyond the base 1 and is provided with a connecting plate 7. A gearbox 8 is provided on the left side of the top wall of the connecting plate 7.

[0026] Furthermore, the lifting cleaning mechanism includes a top plate 12, with one end of an inlet pipe 13 located on the right side of the top wall of the top plate 12, and a hydraulic telescopic rod 14 located on the left side of the top wall of the top plate 12. A cleaning mechanism is located on the drive bottom wall of the hydraulic telescopic rod 14. After the hydraulic telescopic rod 14 is activated, it pushes the rectangular plate 15, connecting pipe 16, connecting seat 17, arc plate 18, nozzle 19 and brush 20 downward to facilitate the connection between the brush 20 and the conveyor roller.

[0027] Furthermore, the cleaning mechanism includes a rectangular plate 15, a connecting pipe 16 between the top wall of the rectangular plate 15 and the top plate 12, and an arc-shaped plate 18 on the bottom wall of the rectangular plate 15 via a connecting seat 17. Multiple nozzles 19 are located in the middle of the inner top wall of the arc-shaped plate 18, and brushes 20 are located on both the front and rear sides of the inner top wall of the arc-shaped plate 18. Cleaning liquid is injected into the top plate 12 through the inlet pipe 13, and then enters the rectangular plate 15, connecting seat 17, and arc-shaped plate 18 through the connecting pipe 16. It is then sprayed out through the nozzles 19 onto the conveyor roller below, softening and rinsing impurities on the outer wall of the conveyor roller. When the conveyor roller rotates, the cleaning liquid sprayed from the nozzles 19 and the brushing action of the brushes 20 clean the conveyor roller.

[0028] Furthermore, multiple nozzles 19 are arranged from left to right between the brushes 20, injecting the cleaning liquid into the top plate 12 through the inlet pipe 13, and then into the rectangular plate 15, the connecting seat 17 and the arc plate 18 through the connecting pipe 16. The cleaning liquid is then evenly sprayed onto the conveying roller below through the multiple nozzles 19.

[0029] Furthermore, the inlet pipe 13, top plate 12, connecting pipe 16, rectangular plate 15, connecting seat 17, arc plate 18 and nozzle 19 are connected to each other. The cleaning liquid is injected into the top plate 12 through the inlet pipe 13, enters the rectangular plate 15, connecting seat 17 and arc plate 18 through the connecting pipe 16, and is sprayed out onto the conveyor roller below through the nozzle 19.

[0030] Furthermore, a counterweight is provided on the right side of the top wall of the top plate 12 to ensure the weight balance on the left and right sides of the top plate 12.

[0031] For those skilled in the art, all electrical components and parts in this case are general standard parts or parts known to those skilled in the art. Their structures and principles can be known to those skilled in the art through technical manuals or conventional experimental methods. All models are compatible with this solution and can operate normally. All electrical components in this case are connected to their compatible power supplies through wires. According to the actual situation, a suitable controller is selected to meet the control requirements. The specific connection and control sequence should refer to the working principle below, and the electrical connection is completed by the sequential operation of each electrical component. The detailed connection method is a well-known technology in the art, and the electrical control will not be described further.

[0032] One specific application of this embodiment is:

[0033] When using this self-cleaning device for the conveyor rollers of a continuous casting machine for aluminum alloy sheet production, the first step is installation. This device is equipped with a fixed base 2, which can be flexibly installed on the support bases at both ends of the conveyor rollers of the continuous casting machine sheet conveyor line by welding or bolting, according to the actual needs of the site. This installation method not only ensures the stability of the device installation, but also provides a convenient installation method, making it easy to adapt to continuous casting machines under different working conditions.

[0034] After installation, the machine enters the working state. Motor 3 is started, and the motor outputs power to make the lead screw 4 connected to it start to rotate. Under the action of the rotation of the lead screw 4, the connecting block 5, which is threaded with the lead screw 4, produces linear displacement. The movement of the connecting block 5 drives a series of components such as the connecting rod 6, the connecting plate 7, and the gearbox 8 to move synchronously. This, in turn, drives the top plate 12, the hydraulic telescopic rod 14, the rectangular plate 15, the connecting seat 17, the nozzle 19, and the brush 20 to move forward or backward together. In this way, the position of the nozzle 19 and the brush 20 can be precisely adjusted until the nozzle 19 and the brush 20 are moved directly above the conveyor roller, preparing for subsequent cleaning operations.

[0035] Once the nozzle 19 and brush 20 reach the designated position, the hydraulic telescopic rod 14 is activated. Upon receiving the command, the hydraulic telescopic rod 14 extends and pushes the rectangular plate 15, connecting pipe 16, connecting seat 17, arc plate 18, nozzle 19, and brush 20 downwards as a whole until the brush 20 contacts the surface of the conveyor roller. At this point, the conveyor roller is activated and begins to rotate. Simultaneously, cleaning fluid is injected into the top plate 12 through the inlet pipe 13. Under pressure, the cleaning fluid enters the rectangular plate 15, connecting seat 17, and arc plate 18 through the connecting pipe 16, and is finally sprayed evenly from the nozzle 19 onto the rotating conveyor roller below. The spraying of the cleaning fluid softens the impurities adhering to the outer wall of the conveyor roller, creating favorable conditions for subsequent brush cleaning. As the conveyor roller continues to rotate, the nozzle 19 continuously sprays out cleaning fluid, while the brush 20 repeatedly brushes the surface of the conveyor roller. The two work together to thoroughly and meticulously clean the conveyor roller, effectively removing various impurities from its surface.

[0036] After the cleaning work is completed, the hydraulic telescopic rod 14 is retracted, which drives the rectangular plate 15, connecting pipe 16, connecting seat 17, arc plate 18, nozzle 19 and brush 20 to move upward and reset. Then, the second motor 10 is started, which drives the driven shaft 11 to rotate. The rotation of the driven shaft 11 drives the top plate 12, hydraulic telescopic rod 14, connecting pipe 16, arc plate 18 and brush 20 to rotate from the left to the right, thereby moving the entire cleaning structure away from the conveyor line. This design effectively avoids the cleaning device from interfering with the plate conveying work, ensuring that the continuous casting machine plate conveying line can smoothly carry out plate conveying operations and realize the orderly alternation of cleaning and conveying work.

[0037] Of course, the above description is not intended to limit the present utility model, nor is the present utility model limited to the examples given above. Any changes, alterations, additions or substitutions made by those skilled in the art within the scope of the present utility model should be protected by the present utility model.
