Description

Technical Field

[0001] This utility model relates to the field of scraper blades, and in particular to a seamless scraper blade assembly. Background Technology

[0002] In industrial production processes such as machining and CNC machine tools, a large amount of metal chips are generated. If these chips are not cleaned up in time, they will not only affect machining accuracy and normal equipment operation, but may also cause injury to operators. Traditional scraper blades are prone to the following installation problems after splicing:

[0003] First, gaps are easily created when two workpieces are joined at the corner after the scraper blades are spliced ​​together.

[0004] Second, when the scraper is adjusted in one direction, the other workpiece at the corner is obviously misaligned, which will cause problems for both adjacent scrapers.

[0005] Third, after the two scraper blades are properly positioned, the connecting holes may deviate, causing the screws to fail to hold in place.

[0006] These installation issues severely impact the performance and lifespan of the scraper blades. Gaps at corner joints easily trap chips, increasing cleaning difficulty and reducing the scraper blade's chip-blocking effectiveness. Significant misalignment at the corners not only affects aesthetics but also leads to unstable scraping function, failing to effectively guide chips to the designated location. Furthermore, misaligned connecting holes prevent screws from being securely fastened, resulting in an unstable scraper blade structure that may loosen or even detach during equipment operation, posing a significant safety hazard to industrial production. Therefore, developing a seamless scraper blade assembly is of significant practical importance. Utility Model Content

[0007] The technical problem solved by this utility model is to provide a seamless scraper assembly that reduces seams and facilitates splicing.

[0008] The technical solution adopted by this utility model to solve its technical problem is: a seamless scraper assembly, including N L-shaped scrapers, the N L-shaped scrapers being connected in sequence to form a bent structure, each L-shaped scraper having an L-shaped elastic scraper tongue on its inner side, and the connecting end of the L-shaped scraper having a rubber section.

[0009] Furthermore, the L-shaped scraper plate is provided with multiple connecting round holes, and universal adjusting shims are provided in the connecting round holes. The universal adjusting shims are used for alignment and connection with the connecting holes of external devices.

[0010] Furthermore, the universal adjusting pad includes a first flange portion and a second flange portion. The diameter of the first flange portion is larger than the diameter of the connecting circular hole, and the diameter of the second flange portion is smaller than the diameter of the connecting circular hole, so that the second flange portion can extend into the connecting circular hole and rotate 360 ​​degrees within the connecting circular hole. It also includes a waist-shaped hole that passes through the first flange portion and the second flange portion.

[0011] Furthermore, one end of the universal adjustment pad is provided with a protrusion, which is located on one side of the second flange and is engaged with the inner side of the L-shaped scraper.

[0012] Furthermore, at least two protrusions are provided.

[0013] Furthermore, the N L-shaped scraper blades include a first L-shaped scraper blade, a second L-shaped scraper blade, a third L-shaped scraper blade, and a fourth L-shaped scraper blade. The second end of the first L-shaped scraper blade is provided with a rubber segment, the first and second ends of the second L-shaped scraper blade are both provided with rubber segments, the first and second ends of the third L-shaped scraper blade are both provided with rubber segments, and the first end of the fourth L-shaped scraper blade is provided with a rubber segment.

[0014] Furthermore, the L-shaped scraper is a one-piece structure.

[0015] The beneficial effects of this utility model are:

[0016] 1. This structure, by designing the scraper plate as an L-shaped structure, can reduce the number of components and make the R-corner a one-piece structure, thereby reducing the generation of gaps at the R-corner.

[0017] 2. The rubber segments in this structure allow operators to easily trim them with scissors or a knife during assembly, ensuring that adjacent scraper blades are tightly connected and reducing the formation of seams.

[0018] 3. The universal adjustment shims in this structure allow the scraper to be connected to the external machine even when the position of the scraper is adjusted, thus reducing the need to consider the compression amount when producing the scraper.

[0019] 4. When the scraper blades are worn out, their position can be adjusted to allow them to continue to be used. Attached Figure Description

Detailed Implementation

[0027] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0028] like Figures 1 to 6 As shown, an embodiment of this application discloses a seamless scraper assembly, including N L-shaped scrapers. The N L-shaped scrapers are connected in sequence to form a bent structure. Each L-shaped scraper has an L-shaped elastic scraper tongue 6 on its inner side, and a rubber segment 5 is provided at the connecting end of the L-shaped scraper.

[0029] During assembly, N L-shaped scraper blades are sequentially connected to form a bent structure corresponding to the machine base, and fixed to the machine base with bolts and other fasteners. During the connection process, the rubber section 5 allows for seamless splicing of adjacent L-shaped scraper blades by simple trimming of the rubber section 5. The L-shaped elastic scraper tongue 6 is made of elastic material and has a bent structure. When the scraper blade assembly is working, it can better conform to the machine base surface, effectively preventing chips from entering the gap between the scraper blade and the machine base. Simultaneously, its elastic properties can buffer the impact force during scraping to a certain extent, extending the service life of the scraper blade.

[0030] In addition, it should be explained that elastic materials can take many shapes. Figure 6 The example shown is just one embodiment.

[0031] This structure, by designing the scraper blade in an L-shape, reduces the number of components. For example, the original straight-edge structure required six straight profile parts, but with the L-shaped design, only four parts are needed. This reduction in the number of parts also reduces the workload and difficulty of assembly. Furthermore, the rounded corners are integrated, reducing gaps at the corners. Additionally, the rubber section 5 allows operators to easily manipulate it with scissors or a knife during assembly, ensuring a tight connection between adjacent scraper blade sections and further minimizing seams.

[0032] In this embodiment, the L-shaped scraper plate is provided with a plurality of connecting round holes 7, and a universal adjusting shim 8 is provided in the connecting round holes 7. The universal adjusting shim 8 is used for alignment and connection with the connecting holes of external devices.

[0033] Specifically, the universal adjusting pad 8 includes a first flange portion 81 and a second flange portion 82. The diameter of the first flange portion 81 is larger than the diameter of the connecting circular hole 7, and the diameter of the second flange portion 82 is smaller than the diameter of the connecting circular hole 7, so that the second flange portion 82 can extend into the connecting circular hole 7 and rotate 360 ​​degrees within the connecting circular hole 7. It also includes a waist-shaped hole 83 that passes through the first flange portion 81 and the second flange portion 82.

[0034] Specifically, during adjustment, first adjust the position of the scraper blades. When adjusting the scraper blade position, the operator can flexibly adjust the angle and position of each L-shaped scraper blade according to the actual layout of the machine and the chip generation situation. After adjustment, rotate the universal adjusting shim 8 360 degrees within the connecting hole 7 to ensure precise alignment and connection between the oblong hole 83 and the connection hole of the external equipment. Once the scraper blade position is determined, pass the bolt through the oblong hole 83 and the connection hole of the external equipment and tighten it to achieve a stable connection between the scraper blade and the external equipment. In this way, even when installed on machine bases of different shapes and sizes, the adjustment and fixation of the scraper blades can be easily completed. This effectively solves the problem of screws being unable to be fixed due to misalignment of the traditional scraper blade connection holes, ensuring the overall structure of the scraper blade is solid and will not loosen or even fall off during equipment operation, thus guaranteeing the safety and stability of industrial production.

[0035] In addition, when the scraper blade wears down, the screws on the scraper blade can be loosened, and then the scraper blade can be adjusted and fixed in the desired direction so that it can continue to be used.

[0036] In this embodiment, one end of the universal adjustment pad is provided with a protrusion 84, which is located on one side of the second flange 82 and is engaged with the inner side of the L-shaped scraper.

[0037] Specifically, the protrusion 84 enhances the connection stability between the universal adjusting shim 8 and the L-shaped scraper. During installation, after the universal adjusting shim 8 is inserted into the connecting hole 7, the protrusion 84 is bent, at which point it tightly engages with the inside of the L-shaped scraper, preventing the shim from falling off during use. This engaging method is not only simple and reliable but also eliminates the need for additional fasteners, reducing assembly costs and complexity. Furthermore, the protrusion 84 is designed for easy disassembly. When the universal adjusting shim 8 needs to be replaced or adjusted, the protrusion 84 is straightened, allowing the operator to easily remove it from the L-shaped scraper.

[0038] In this embodiment, at least two protrusions 84 are provided.

[0039] Specifically, this design further enhances the connection strength between the universal adjusting shim 8 and the L-shaped scraper. Multiple protrusions 84 can distribute the connection force, reducing the pressure on each individual protrusion 84.

[0040] In this embodiment, the N L-shaped scraper blades include a first L-shaped scraper blade 1, a second L-shaped scraper blade 2, a third L-shaped scraper blade 3, and a fourth L-shaped scraper blade 4. The second end of the first L-shaped scraper blade 1 is provided with a rubber segment 5. The first and second ends of the second L-shaped scraper blade 2 are both provided with rubber segments 5. The first and second ends of the third L-shaped scraper blade 3 are both provided with rubber segments 5. The first end of the fourth L-shaped scraper blade 4 is provided with a rubber segment 5.

[0041] Specifically, in this specific embodiment, such as Figure 1 As shown, the first L-shaped scraper 1, the second L-shaped scraper 2, the third L-shaped scraper 3, and the fourth L-shaped scraper 4 are sequentially spliced ​​at designated positions on the machine. During the splicing process, the rubber segments 5 at the connecting ends can be trimmed to ensure a tight fit between adjacent scraper plates without gaps. For example, when splicing the first L-shaped scraper 1 and the second L-shaped scraper 2, the operator can use scissors or a knife to appropriately trim the rubber segments 5 at the second end of the first L-shaped scraper 1 and the first end of the second L-shaped scraper 2, allowing the two rubber segments 5 to cooperate and fill the gap at the splice, thus achieving a seamless splice. This method of achieving a seamless splice by trimming the rubber segments 5 not only improves the overall sealing of the scraper assembly, effectively preventing chips from getting stuck in the splice gaps and reducing cleaning difficulty, but also enhances the scraper's chip-blocking effect, ensuring the stability and effectiveness of the scraping function.

[0042] In this embodiment, the L-shaped scraper is an integral structure.

[0043] It should be explained that the L-structure is just a structural form. The corner angle of the L-shaped scraper can be any angle, such as 90 degrees, 110 degrees, 120 degrees, 130 degrees, etc.

[0044] Specifically, because the L-shaped scraper is a one-piece structure, there are no gaps at its rounded corners. This one-piece design avoids the gap problem caused by loose splicing at the rounded corners of traditional spliced ​​scrapers. In practical applications, the one-piece L-shaped scraper can better adapt to the complex shape of the machine tool and conform to the machine surface. The one-piece structure also improves the overall strength and stability of the scraper, allowing it to withstand greater external impacts during equipment operation without easily deforming or being damaged. This further ensures the normal operation of the scraping process and provides reliable protection for industrial production.

[0045] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above descriptions are merely specific embodiments of this utility model and are not intended to limit this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
