Description

Technical Field

[0001] This invention relates to the field of chip removal equipment, and more specifically, to a floating scraper structure for a chip conveyor. Background Technology

[0002] In traditional chip conveyors, a certain gap is usually left between the scraper and the base plate to ensure smooth installation, tolerate manufacturing errors, and avoid interference during operation. However, this gap often leads to the following problems in practice: First, chip residue: particles smaller than the gap size accumulate inside the chip conveyor, stubbornly piled up, resulting in incomplete chip removal and requiring frequent manual cleaning. Second, foreign objects can get stuck: broken tools, burrs from machined parts, and screws can easily get stuck in the gap, causing the chip conveyor to stop, scraper deformation or damage, chain skipping or breakage, and other malfunctions. Third, chip removal efficiency is low: when the scraper moves to the inclined section of the chip conveyor, if the gap is too large, some chips (especially fine and powdery chips) will leak back through the gap and cannot be effectively conveyed to the collection box. Summary of the Invention

[0003] Therefore, it is necessary to provide a floating scraper structure to address the problem of chip jamming caused by the pre-reserved gap in the existing scraper structure. This floating scraper structure can adapt to foreign objects, significantly reduce the risk of jamming, and make the equipment operation more stable and reliable.

[0004] A floating scraper structure is provided for a chip conveyor. The floating scraper structure includes two chains surrounding the chip conveyor and a plurality of scrapers evenly disposed between the two chains. A plurality of mounting seats are provided on the chains for mounting the scrapers. Limiting sleeves are provided on both sides of each scraper, the thickness of which is greater than the thickness of the scraper, creating a reliable gap between the scraper and the limiting sleeve, thus providing a constant floating gap for the scraper in the chip-scraping direction. Each mounting seat has mounting holes corresponding to the limiting sleeves, and bolts are used to float the scraper and the mounting seat through the limiting sleeves and mounting holes.

[0005] Furthermore, the scraper is provided with waist-shaped holes on both sides, the length direction of the waist-shaped holes is perpendicular to the scraping direction of the scraper, the waist-shaped holes correspond to the mounting holding, the length of the waist-shaped holes is greater than the shaft diameter of the limiting sleeve, and the limiting sleeve is installed in the waist-shaped holes.

[0006] Furthermore, a gasket is provided between the bolt and the limiting sleeve.

[0007] Furthermore, the mounting base is an "L-shaped" mounting base, one side of which is connected to the chain, and the other side of which is used to mount the scraper.

[0008] Furthermore, the back of the scraper is provided with reinforcing ribs, and the front of the scraper has a planar structure.

[0009] Furthermore, the limiting sleeve is made of an elastic material.

[0010] Furthermore, an elastic ring is fitted inside the waist-shaped hole.

[0011] This invention provides a floating scraper structure with oblong holes on both sides of the scraper. A limiting sleeve is installed within each oblong hole. A bolt passes through the limiting sleeve and a mounting hole on the mounting base, causing the scraper to be floatingly connected to the mounting base on the chain. The end of the bolt away from the scraper is locked with a self-locking nut. Because the thickness of the limiting sleeve is greater than the thickness of the scraper, a reliable gap is formed between the scraper and the limiting sleeve, resulting in a constant floating gap in the scraping direction and ensuring the stability of the scraper during operation. Furthermore, the limiting sleeve is installed within the oblong holes on the scraper, creating a floating gap in the radial direction as well. When the scraper encounters an obstacle, such as a broken blade or large burrs, it can rise to prevent jamming. After overcoming the obstacle, the scraper continues to fall under gravity, completing the scraping process. Attached Figure Description

[0018] To facilitate understanding of the present invention, a more complete description will be given below with reference to the accompanying drawings. Preferred embodiments of the invention are shown in the drawings. However, the invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a thorough and complete understanding of the disclosure of the invention.

[0019] It should be noted that when an element is referred to as being "set on" another element, it can be directly on the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," "top," "bottom," "end," "top," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0020] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0021] This invention provides a floating scraper structure for a chip conveyor. The floating scraper structure includes two mutually selecting chains surrounding the chip conveyor and a plurality of scrapers evenly disposed between the two chains. A plurality of mounting seats for mounting the scrapers are provided on the chains. Limiting sleeves are provided on both sides of each scraper, the thickness of the limiting sleeves being greater than the thickness of the scraper. Each mounting seat has mounting holes corresponding to the limiting sleeves. A bolt passes through the limiting sleeves and the mounting holes to float and connect the scraper to the mounting seat.

[0022] This invention provides a floating scraper structure, which has oblong holes on both sides of the scraper, and a limiting sleeve is installed in the oblong holes. After the bolt passes through the limiting sleeve and the mounting hole on the mounting base, the scraper is floatingly connected to the mounting base on the chain. The end of the bolt away from the limiting sleeve is locked by a self-locking nut. Because the thickness of the limiting sleeve is greater than the thickness of the scraper, a reliable gap is formed between the scraper and the limiting sleeve, so that the scraper has a constant floating gap in the scraping direction, thereby ensuring the stability of the scraper during operation.

[0023] The following description, in conjunction with specific embodiments, illustrates a floating scraper structure to further understand the inventive concept of the floating scraper structure.

[0024] In one embodiment, such as Figure 1-3 As shown, the floating scraper structure 200 is used for scraping chips from the chip conveyor 100, that is, scraping the chips inside the chip conveyor 100 to the chip outlet for discharge. The floating scraper structure 200 includes two parallel chains 210 surrounding the chip conveyor 100 and a plurality of scrapers 220 evenly arranged between the two chains 210. The chains 210 are arranged around the chip conveyor 100 along its extension direction, that is, the chains 210 drive the scrapers 220 to rotate. A plurality of mounting seats 230 are provided on the chains 200 for mounting the scrapers 220, that is, mounting seats 230 are respectively provided on the inner side of the two chains 200, and the scrapers 220 are mounted on the sides. Do not install on the mounting base 230; each scraper 220 is also provided with a limiting sleeve 221 on both sides, the thickness of the limiting sleeve 221 is greater than the thickness of the scraper 220, each mounting base 230 is provided with a mounting hole 231 corresponding to the limiting sleeve 221, and the scraper 220 and the mounting base 230 are floated by a bolt 240 passing through the limiting sleeve 221 and the mounting hole 241, and the end of the bolt away from the scraper 220 is locked by a self-locking nut.

[0025] like Figure 3 As shown, the scraper 220 has waist-shaped holes 222 on both sides. The length of the waist-shaped holes 222 is perpendicular to the scraping direction of the scraper 220. The waist-shaped holes 222 correspond to the mounting holes 231. The length of the waist-shaped holes 222 is greater than the shaft diameter of the limiting sleeve 220. The limiting sleeve 220 is installed in the waist-shaped holes 222.

[0026] In this invention, the scraper 220 is mounted on the mounting base 230 of the chain 200 via a limiting sleeve 221 and bolts 240. After installation, the end of the bolt 240 is locked with a self-locking nut 241, thus maintaining a constant distance between the self-locking nut 241 and the bolt 240 nut. Since the axial thickness of the limiting sleeve 221 is greater than the thickness of the scraper, a reliable gap is formed between the scraper 220 and the limiting sleeve 221, ensuring a constant floating gap in the scraping direction and guaranteeing the stability of the scraper during operation. Furthermore, in this invention, the limiting sleeve 221 is installed within the oblong hole 222 on the scraper 220, providing a floating gap in the radial direction as well. When the scraper encounters an obstacle, such as a broken blade or large burrs, it can rise to prevent jamming. After overcoming the obstacle, the scraper continues to fall under gravity, completing the scraping process.

[0027] In another embodiment, a washer 241 is provided between the bolt 240 and the limiting sleeve 221.

[0028] In another force of action, such as Figure 4As shown, the mounting base 230 is an "L-shaped" mounting base. One side of the "L-shaped" mounting base is connected to the chain 210, and the other side of the "L-shaped" mounting base is used to install the scraper 220. Specifically, the L-shaped mounting base has a mounting hole 231 on the side perpendicular to the chain. The bolt 240 passes through the washer 241, the limiting sleeve 221, and the mounting hole 231 in sequence and is then locked by the self-locking nut 241.

[0029] In another embodiment, the back of the scraper 220 is provided with reinforcing ribs 223, and the front of the scraper 220 is a planar structure.

[0030] In another embodiment, the limiting sleeve 220 is made of an elastic material. It provides cushioning when the scraper 220 floats up and down when encountering an obstacle, or when it floats in the scraping direction.

[0031] In another embodiment, an elastic ring is fitted inside the waist-shaped hole 222, which similarly provides cushioning when the scraper floats up and down.

[0032] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0033] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
