Description

Technical Field

[0001] This utility model relates to the field of pinch roller processing technology, specifically to a double-sided shearing pinch roller scraper device. Background Technology

[0002] When shearing steel plates, foreign objects such as cutting slag, brick debris, sludge, and chalk dust may remain on the surface of the steel plate or the double-sided shearing pinch rollers. Under the clamping force of the pinch rollers, these foreign objects easily adhere to the surface of the pinch rollers, causing quality defects such as pits and indentations on the steel plate surface. In terms of product quality, in terms of appearance, impurities such as cutting slag, brick debris, sludge, and chalk dust will make the steel plate surface uneven, with bumps, depressions, or scratches, resulting in uneven color and greatly affecting the product's aesthetics. At the same time, these impurities may damage the steel plate's microstructure, reducing its strength, hardness, toughness, and other mechanical properties, becoming stress concentration points under stress, and increasing the risk of steel plate fracture. In addition, impurities such as sludge can also reduce the steel plate's corrosion resistance and shorten the product's service life. In terms of production process, during processing, impurities will wear down cutting tools and molds, reducing equipment lifespan, and will also affect processing accuracy, increasing product dimensional deviations, and even leading to defects. During welding, impurities may cause defects such as porosity and slag inclusions in the weld, affecting the weld strength. When painting, impurities can affect the adhesion of the paint, making the coating easy to peel off, which affects both the appearance and the protective function. When impurities appear on the steel plate or pinch roller, they are usually cleaned manually.

[0003] However, manual cleaning is relatively inefficient. The cleaning process requires a lot of time and manpower, especially when there are many impurities or the steel plate and pinch roller area is large. In such cases, the cleaning is not thorough and the cleaning speed is slow, which affects the production progress and reduces the overall efficiency of the production line. Utility Model Content

[0004] The purpose of this utility model is to provide a double-sided shearing pinch roller scraper device to solve the problems of relatively low efficiency of manual cleaning, the need for a lot of time and manpower in the cleaning process, especially when there are many impurities or the steel plate and pinch roller area are large, the cleaning is easy to be incomplete and the cleaning speed is slow, which affects the production progress and reduces the overall efficiency of the production line.

[0005] To achieve the above objectives, the basic solution provided by this utility model is as follows: a double-sided shearing pinch roller scraper device, including a support, a pinch roller, a rotating shaft, a scraper and a base. The rotating shaft is fixedly connected to the support, and the pinch roller is rotatably connected to the rotating shaft. A crossbeam is provided on the support, and several strip-shaped through holes I are opened on the crossbeam. Several strip-shaped through holes II are opened on the scraper. Bolts are movably inserted into the several strip-shaped through holes I and II. Nuts are threaded onto the bolts. The scraper is detachably connected to the crossbeam through the bolts and nuts. The support is fixedly connected to the base.

[0006] The principle and beneficial effects of this utility model are as follows: The scraper is placed on the crossbeam, with the first and second strip-shaped through holes corresponding to each other. Then, the scraper is connected to the crossbeam using bolts. When scraping the pinch roller, the bolts and nuts can firmly fix the scraper in its position. If the scraper moves backward or forward after a long period of use, the position of the scraper can be adjusted by adjusting the bolts and nuts. The range of movement is also within the range of the strip-shaped through holes, so as not to cause significant damage to the opening of the scraper. Through this improved installation, the relative movement of the scraper and the roller ring forms a scraping effect. When the pinch roller moves, the scraper continuously acts on the surface of the pinch roller, continuously cleaning the surface of the pinch roller.

[0007] Option 2, a preferred option of the basic scheme, features a hinged bracket that connects the bracket to the crossbeam. When the scraper is not needed, the crossbeam can be raised; when the scraper is required, it can be lowered. Prolonged friction between the pinch roller and the scraper damages both.

[0008] Option 3, an optimal choice from the basic option, involves a scraper composed of several blades joined together. Each blade has a protrusion at one end and a groove at the other, with the protrusion and groove engaging. During use, the number of blades can be adjusted to achieve the desired scraper length based on the required cleaning length.

[0009] Option 4, an optimal choice from Option 3, uses a stainless steel scraper. During production, the scraper may come into contact with various corrosive substances and frequently rub against the pinch rollers. Stainless steel has a certain degree of corrosion resistance and strong wear resistance, which reduces the frequency of replacement while resisting corrosion.

[0010] Option 5, a preferred option of Option 4, involves installing compression springs within several of the two strip-shaped through holes. One end of the compression spring is fixed to the second strip-shaped through hole, while the other end abuts against the bolt. The compression springs hold the bolt in place, further reducing the positional misalignment between the scraper and the bolt.

[0011] Option six, a preferred embodiment of option four, features a scraper with several limiting holes, through which the bolts movably pass. Using bolts through the limiting holes to fix the scraper to the crossbeam also increases the stability and robustness of the scraper during the scraping process. Attached Figure Description
