Description

Technical Field

[0001] The utility model belongs to the technical field of industrial production, and particularly relates to a pneumatic scraper structure with a ejector rod that can be flipped by 90°. Background Art

[0002] At present, in the production process of battery electrodes, electrode rolling is an essential process. During the negative electrode rolling process, the roll surface of the rolling mill is very prone to dirt. Therefore, negative electrode rolling mills are equipped with roll wiping devices and scraper devices. The scraper device uses a special blade to fit the roll surface, scrape off solid particles, dust and other dirt adhered to the roll surface, and suck it away with negative pressure to keep the roll surface clean. In order to avoid damage to the scraper blade during the production process, resulting in incomplete scraping and damage to the rolling mill, it is generally required to replace the scraper blade once per shift. However, due to space limitations and the limitations of the working structure of the scraper, when employees replace the scraper blade, there are problems such as difficult operation, long time consumption, and poor installation accuracy of the blade.

[0025] Next, the present utility model will be further described in conjunction with the attached drawings.

[0026] A pneumatic scraper structure with a push rod that can be flipped by 90°, including a push rod cylinder structure and a scraper assembly. The push rod of the push rod cylinder structure abuts against the top block of the scraper assembly, so that the scraper in the scraper assembly fits the roller surface. It is characterized in that it further includes a flipping structure;

[0027] The flipping structure includes a fixing bracket, a cylinder mounting plate, a cylinder rotating shaft, an upper stop block and a front stop block; one end of the fixing bracket is fixedly installed on the support seat of the rolling mill, and the other end is connected to the cylinder rotating shaft through a bearing; the cylinder in the push rod cylinder structure is installed on the cylinder mounting plate; the outer end of the cylinder rotating shaft is fixedly connected to the cylinder mounting plate;

[0028] The cylinder rotating shaft is of an L-shaped structure, including two mutually perpendicular parts. One part is used as a shaft and is connected to the fixing bracket through a bearing, and the other part is provided with a screw I threadedly connected thereto; both the upper stop block and the front stop block are provided with long holes and notches; the screw II passes through the long hole and is threadedly connected to the fixing bracket, and the screw I is located in the corresponding notch.

[0029] Further, the extending direction of the long hole is perpendicular to the rotation plane of the cylinder.

[0030] Further, the push rod cylinder structure includes a cylinder and a top plate installed at the operating end of the cylinder; a plurality of screws III threadedly connected thereto are arranged in an array on the top plate, and the ends of the screws III abut against the top block of the scraper assembly.

[0031] Further, the scraper assembly includes a scraper, a top block and a scraper side plate; the scraper is installed between the lower bottom plate of the scraper and the upper clamping plate of the blade; the lower bottom plate of the scraper is fixedly connected to the top block and is hinged to the scraper side plate fixed on the fixing bracket, and its hinge shaft is perpendicular to the scraper side plate.

[0032] Further, it further includes a dust suction box; the dust suction opening of the dust suction box is located below the scraper and faces the scraper directly.

[0033] Figure 1 It is a schematic diagram of the working state of the scraper:

[0034] The cylinder pushes out, driving the push rod to press against the scraper bottom plate and rotate it toward the roller, so that the scraper blade fits tightly against the roller and continuously scrapes away the solid particles, dust and other impurities remaining on the roller.

[0035] Figure 2 , Figure 3 and Figure 4 This is a detailed structural diagram of the scraper: the scraper upper clamping plate and the scraper lower base plate are connected by a row of screws evenly arranged horizontally, so that the scraper blade is tightly pressed in the middle.

[0036] The lower end of the cylinder plunger is connected to the top plate, on which a row of threaded holes are evenly arranged. The push rod is fixed to the top plate through these threaded holes, and its appropriate position on the top plate can be adjusted through the threads so that when the cylinder is pushed out, it is pressed against the top block below, forcing the scraper bottom plate to rotate toward the roller, so that the scraper blade fits against the roller.

[0037] Figure 3 The cylinder is in the retracted state. Due to space limitations, the cylinder stroke can only be 20mm. It can be found that when the cylinder is retracted, the scraper base plate can only rotate 23.7° in the opposite direction. At this time, the scraper blade is still facing the direction of the roller, which makes it inconvenient for employees to operate and replace the scraper blade.

[0038] This problem can be easily solved by flipping the structure. Figure 5 , Figure 6 :

[0039] A bearing hole is processed on the cylinder fixing bracket 8, and the cylinder is connected to the cylinder shaft through the cylinder mounting plate 5. The cylinder shaft is fixed to the cylinder fixing bracket through two bearings, a bearing spacer, a shaft elastic ring and a hole elastic ring.

[0040] Front block 7 and upper block 6 (specific structure refer to Figure 9 ) has a long hole on it and is fixed to the cylinder fixing bracket by screws. During normal operation, the cylinder moves vertically downward, and the cylinder fixing shaft is connected by screws through the front block and the upper block. At this time, the air shaft cannot rotate due to the restrictions of the front block and the upper block, thereby keeping the cylinder in a vertical downward state.

[0041] When the scraper blade needs to be replaced, loosen the screws that fix the front block and the upper block (do not remove the screws, as long as the blocks can slide left and right), push the two blocks by hand to move them to the left (the right one moves to the right) until the blocks leave the rotating space of the cylinder shaft. Figure 7 .

[0042] At this time, the ejector rod of the scraper can freely rotate outwards along with the top plate, the cylinder, the cylinder mounting plate and the cylinder rotating shaft. When it rotates outwards by 90°, and the cylinder and the ejector rod are in a horizontal state, the screw on the cylinder rotating shaft is in a vertical state and just aligns with the notch on the upper stop block. At this time, push the upper stop block to move to the right (or move to the left on the right side) to make the screw inside the notch. At this time, the cylinder and the ejector rod maintain a horizontal state and cannot rotate, creating an operating space at the lower part. The scraper bottom plate can rotate freely, which is convenient for replacing the scraper blade. As Figure 8 .

[0043] Therefore, through the design of the cylinder ejector rod flipping structure, on the premise of saving the cylinder stroke, the operating space for replacing the scraper blade can be quickly released, saving operation time, and the installation accuracy of the scraper blade is easier to be guaranteed.

[0044] It should be understood that the above description of the specific implementation manner of this patent is only an exemplary description listed for the convenience of those of ordinary skill in the art to understand the patent solution, and does not imply that the protection scope of this patent is only limited to these examples. Those of ordinary skill in the art can fully understand the patent technical solution and, without any creative labor, obtain more specific implementation manners by combining technical features, replacing some technical features, adding more technical features, etc. to the examples listed in this patent. All these specific implementation manners are within the scope covered by the claims of this patent. Therefore, these new specific implementation manners should also be within the protection scope of this patent.

Obviously, these schemes should also be included in the protection scope of this patent.
