Description

Technical Field

[0001] This utility model relates to the technical field of high viscosity fluid scraping devices, specifically to a scraping tool. Background Technology

[0002] Conductive paste is an important component in the screen printing process of solar cells. Because its main component is precious metal, it accounts for a high proportion of the overall cost of cell manufacturing. Due to the high viscosity of conductive paste, existing recycling tools mostly use scrapers or squeegees to scrape the paste off the screen. Existing squeegees are usually made of utility knives to scrape the conductive paste off, but utility knives cannot be trimmed according to the product appearance, and can only be operated by the operator's skill, resulting in low work efficiency. Utility Model Content

[0003] Therefore, the technical problem to be solved by this utility model is to overcome the shortcomings of the prior art, which is that wallpaper knives cannot be trimmed according to the appearance of the product and can only be operated by the skill of the operator, resulting in low work efficiency. Thus, a glue scraping knife is provided.

[0004] To address the aforementioned technical problems, this utility model provides a scraping tool, comprising:

[0005] A handle, the end of which is connected to a tool holder;

[0006] The blade holder is equipped with blades suitable for scraping slurry;

[0007] A guide wheel is rotatably mounted on the tool holder, and the guide wheel is located on one side of the blade, with the guide wheel protruding from the side of the tool holder.

[0008] Optionally, a positioning hole is provided on the side of the blade away from the cutting edge.

[0009] Optionally, the positioning hole is a strip-shaped hole that extends toward the cutting edge of the blade.

[0010] Optionally, the bottom surface of the tool holder on which the blade is mounted has an inclined portion, and the blade is adapted to be mounted on the inclined portion.

[0011] Optionally, it may also include a wedge block adapted to be placed between the blade and the inclined portion.

[0012] Optionally, the tool holder includes a fixing part, and the tool holder is connected to the end of the handle through the fixing part.

[0013] Optionally, there are two guide wheels, which are located on both sides of the blade and extend out of the side of the blade holder.

[0014] Optionally, the positioning holes have two that are arranged opposite to each other.

[0015] The technical solution of this utility model has the following advantages:

[0016] 1. The scraping tool provided by this utility model has a tool holder mounted on the handle, a blade mounted on the tool holder, and a guide wheel mounted on the tool holder. The guide wheel can roll along the edge of the workpiece to be scraped. When the operator operates the tool to roll along the edge of the workpiece, the cutting edge of the blade scrapes off the excess slurry on the surface of the workpiece. It can quickly scrape off the slurry on the surface and edge of the workpiece without relying on the operator's skill level, and the operation is simple.

[0017] 2. The adhesive scraping tool provided by this utility model has a positioning hole on the blade. The positioning hole is a strip-shaped hole. By adjusting the fixed position of the strip-shaped hole, the length of the blade extending out of the blade holder can be adjusted, that is, the scraping size of the adhesive scraping tool can be adjusted so that the adhesive scraping tool can be used in more application scenarios.

[0018] 3. The adhesive scraper provided by this utility model has an inclined part on the bottom surface of the blade holder. By controlling the contact angle between the blade and the inclined part, the tilt angle of the blade can be adjusted so that the blade can be used in more application scenarios.

[0030] Example

[0031] This embodiment provides a specific implementation method for a scraping tool, such as... Figure 1 and Figure 2 As shown, the device includes a handle 1, a blade holder 2, a blade 3, and a guide wheel 4. The blade holder 2 is connected to the end of the handle 1, the blade 3 is mounted on the blade holder 2, and the guide wheel 4 is rotatably mounted on the blade holder 2, located to one side of the blade 3. The guide wheel 4 protrudes from the side of the blade holder 2, allowing it to roll in close contact with the edge of the workpiece to be coated. When the operator rolls the blade along the edge of the workpiece, the cutting edge of the blade 3 scrapes away excess adhesive from the surface of the workpiece. This method quickly removes adhesive from the surface and edges of the workpiece without requiring operator skill, making it simple to operate.

[0032] As an alternative implementation, the guide wheels 4 can also be configured as two, with the two guide wheels 4 located on both sides of the blade 3 and both extending out of the side of the blade holder 2.

[0033] In this embodiment, as Figure 3 and Figure 4 As shown, the bottom surface of the tool holder 2 has two fixing holes 23, and the blade 3 has two positioning holes 31. The blade 3 is placed against the bottom surface of the tool holder 2, aligning the positioning holes 31 with the fixing holes 23, and then secured with bolts to complete the fixed installation of the blade 3 and the tool holder 2. The positioning holes 31 are strip-shaped holes with a certain length. Moving the blade 3 along the length of the positioning holes 31 adjusts the length of the blade 3 extending beyond the tool holder 2. After adjusting the distance, the bolts are tightened to allow the tool to adapt to different workpieces to be scraped, achieving a fast and uniform cutting effect.

[0034] Specifically, a guide hole 22 is provided on the bottom surface of the tool holder 2. The guide wheel 4 is rotatably installed in the guide hole 22 via a rotating shaft. The rotating shaft is fixedly installed in the guide hole 22, and the guide wheel 4 is rotatably installed on the rotating shaft. The rotating shaft is provided with a blocking block to prevent the guide wheel 4 from falling off. Specifically, the blocking block can be a nut.

[0035] In this embodiment, an inclined portion 21 is provided on the bottom surface of the tool holder 2. The inclined portion 21 is adapted to the width of the blade 3, and the inclined direction of the inclined portion 21 is to be recessed into the tool holder 2. The blade 3 can be adjusted to be parallel to the surface of the workpiece to be coated, or it can be adjusted to be at a certain angle to the surface of the workpiece to be coated. By controlling the contact angle between the blade 3 and the inclined portion 21, the inclination angle of the blade 3 can be adjusted so that the tool can be used in more application scenarios.

[0036] It also includes a wedge block placed between the blade 3 and the inclined part 21, and the angle of the blade 3 can be adjusted by the insertion depth of the wedge block.

[0037] In this embodiment, the tool holder 2 also includes a fixing part, and the end of the handle 1 is connected to the fixing part.

[0038] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this utility model.
