Description

Technical Field

[0001] This utility model relates to the field of woodworking edge banding machines, specifically a novel polygonal blade anti-clogging edge scraping assembly for woodworking edge banding machines. Background Technology

[0002] The edge banding machine scraping assembly is a key component in the edge banding machine used to eliminate wavy marks on the surface of the board after trimming and improve the quality of edge banding. It uses a high-precision scraper to scrape the upper and lower edges of the board in an arc shape, making the transition between the edge banding tape and the board smoother and flatter. At the same time, it removes the thin layer of edge banding material left after fine trimming, ensuring that there are no wavy marks or excess glue marks on the edge of the board, and ultimately achieving a refined edge banding effect and improved aesthetics.

[0003] Currently, the edge banding machine industry uses conventional double-blade or single-blade edge scraping assemblies, which wear out and need to be replaced quickly. They cannot be customized with different rounded blades for different furniture manufacturers or processes. In addition, the scraped wire is particularly prone to getting tangled around the scraper blade, causing the scraper to skip or fail to scrape the board, seriously affecting the product quality. Therefore, to address the above problems, a new type of polygonal blade anti-clogging edge scraping assembly for woodworking edge banding machines is proposed. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0029] The following is in conjunction with the appendix Figure 1-9 This application will be described in further detail.

[0030] This application discloses a novel polygonal blade anti-clogging edge-scraping assembly for woodworking edge banding machines. (Refer to...) Figures 1-9The woodworking edge banding machine's new polygonal blade anti-clogging edge scraping assembly includes three base frames 1. Each base frame 1 has a fixedly installed column 2. Two vertical frames 3 are slidably connected to the surface of each column 2. A horizontal column 31 runs through the interior of each vertical frame 3. A horizontal frame 4 is slidably connected to the surface of each horizontal column 31. A horizontal support spring 41 is fixedly installed on the opposite side of the vertical frames 3 and the horizontal frame 4. A fixing frame 5 is provided on one side of the base frame 1. An avoidance component 52 is provided on the surface of the fixing frame 5, which works in conjunction with the vertical frames 3. An avoidance cylinder 51 is fixedly installed on the surface of the fixing frame 5, which works in conjunction with the avoidance component 52. A mounting frame 9 is fixedly installed on the surface of the horizontal frame 4. A blade holder 95 is slidably connected to the surface of the mounting frame 9. A scraper 10 is fixedly installed on one side of the base frame 5. Adjustment components 6 are provided on the surfaces of all six cross frames 4. A first side plate 7, a second side plate 71, and a third side plate 72 are rotatably installed on one side of each of the six cross frames 4 via the adjustment components 6. A first horizontal support plate 8, a second horizontal support plate 81, and a third horizontal support plate 82 are rotatably installed on the opposite sides of two cross frames 4 via the adjustment components 6. An upper pressure spring 102 and a lower push spring 101 are fixedly connected inside the base frame 1, and the upper pressure spring 102 and the lower push spring 101 are used in conjunction with two cross frames 4 respectively. A filament extraction dust suction hood 92 is fixedly installed on the surface of each of the six blade holders 95, and the filament extraction dust suction hood 92 is used in conjunction with the scraper 10. An air blowing block 91 is fixedly installed on one side of the blade holder 95, and the air blowing block 91 is connected to the filament extraction dust suction hood 92. The dust collection hood 92 is used in conjunction with the servo motor 93, which is fixedly mounted on the surface of each of the two mounting brackets 9. The output end of the servo motor 93 is fixedly connected to the ball screw 94. The two blade holders 95 are threaded onto the surfaces of the two ball screws 94. The scraper 10 is fixedly mounted on the blade holder 95 with hexagonal bolts. The scraper 10 is a polygonal blade with four-sided, six-sided, and eight-sided cutting edges, etc. The radius of the cutting edges varies, and the radius of the cutting edges includes R1.0, R1.2, R1.5, R2.0, R3.0, etc., to adapt to the scraping requirements of different thickness plates. The scraper 10 can be replaced with a four-sided scraper 10, a six-sided scraper 10, an eight-sided scraper 10, etc., as needed. In addition, the scraper 10 also... A straight-edged chamfered scraper 10 can be used, and it can also be replaced with a four-sided scraper 10, a six-sided scraper 10, an eight-sided scraper 10, etc., as needed. For example, the blade angle of the four-sided straight-edged chamfered scraper 10 is 45° and the length is 4.95, so as to adapt to different materials of the board. Among them, the air blowing block 91 is located on the back of the scraper 10, and the scraper 10 is located between the air blowing block 91 and the filament discharge dust suction hood 92. The angle of the air blowing hole of the air blowing block 91 corresponds to the position of the air inlet of the filament discharge dust suction hood 92. The specifications of the air blowing block 91 can be adapted and adjusted according to the filament discharge dust suction hood 92 of different scraping assemblies. A pressure regulating valve is provided on the air pipe connected to the air blowing block 91 so as to adjust the blowing intensity according to different materials and ensure the stable operation of the filament discharge function.

[0031] In the single-side edge scraping assembly, during the conveying of the sheet material, the sheet material contacts the first horizontal support plate 8 and is pressed backward, ensuring that the spring force acts on the side of the sheet material through the first horizontal support plate 8. When the sheet material contacts the two first side support plates 7, the two opposite first side support plates 7 are pressed downward and upward, ensuring that the upper pressure spring 102 and the lower top spring 101 act on the upper and lower surfaces of the sheet material through the first side support plates 7. Then, the scraper 10 with selected rounded corner four-sided scraper 10, six-sided scraper 10 or eight-sided scraper 10 is used directly for flat scraping, so that the scraper 10 works on the upper and lower edges of the sheet material, thereby stably scraping out the desired product effect.

[0032] During the sheet material conveying process, the L-shaped scraping assembly successively contacts the two second horizontal support plates 81 and presses them backward, ensuring that the spring force acts on the side of the sheet material through the second horizontal support plates 81. The sheet material then contacts the two second side support plates 71, and the corresponding upper second side support plate 71 is pressed downward, ensuring that the lower upper pressure spring 102 acts on the bottom of the sheet material through the second side support plate 71. Then, it contacts the second horizontal support plate 81 and presses it backward, ensuring that the spring force acts on the side of the sheet material through the second horizontal support plate 81. Finally, it contacts the left second side support plate 71 and presses the corresponding lower second side support plate 71 upward, ensuring that the upper lower top spring 101 acts on the top of the sheet material through the second side support plate 71. Then, by selecting a rounded scraper 10, the scraper 10 works on the upper and lower edges of the sheet material and discharges the scraped filaments from the filament extraction dust hood 92, thereby stably scraping out the desired product effect.

[0033] In the servo scraping assembly, during the sheet material conveying process, the sheet material contacts one of the third horizontal support plates 82 and is pressed backward, ensuring that the spring force acts on the side of the sheet material through the third horizontal support plate 82. The sheet material then contacts two third side support plates 72, causing the corresponding third side support plates 72 to be pressed downward, ensuring that the upper pressure spring 102 below acts on the underside of the sheet material through the third side support plate 72. Then, the sheet material contacts another third horizontal support plate 82 and is pressed backward, ensuring that the spring force acts on the side of the sheet material through the third horizontal support plate 82, and interacts with the upper left third side support plate 82. The plate 72 contacts and presses the corresponding third side plate 72 upward to ensure that the upper bottom spring 101 acts on the board through the third side plate 72. Then, by selecting the rounded corner scraper 10, the scraper 10 works on the upper and lower edges of the board and discharges the scraped filaments from the filament dust suction hood 92, thereby stably scraping out the desired product effect. During the adjustment of the equipment, the position of the blade holder 95 can be precisely adjusted by the servo motor 93 and the ball screw 94, thereby adjusting the position of the scraper 10 to adjust the scraping amount, so that the equipment can perfectly complete the scraping work.

[0034] Reference Figure 4The avoidance assembly 52 includes a support rod 5201, which is fixedly connected to the telescopic end of the avoidance cylinder 51. A first bracket 5202 is fixedly mounted on the surface of the vertical frame 3. One end of the support rod 5201 passes through the first bracket 5202 and is slidably connected to the inner cavity of the first bracket 5202. An avoidance spring 5203 and a shock-absorbing spring 5204 are slidably sleeved on both sides of the surface of the support rod 5201, respectively. One end of the avoidance spring 5203 is fixedly connected to the surface of the support rod 5201, and the other end of the avoidance spring 5203 is fixedly connected to one side of the first bracket 5202. One end of the shock-absorbing spring 5204 is connected to the support rod. One end of 5201 is fixedly connected, and the other end of the shock-absorbing spring 5204 is fixedly connected to the other side of the first bracket 5202. The position of the support rod 5201 inside the first bracket 5202 is stabilized by the avoidance spring 5203 and the shock-absorbing spring 5204, and one end of the support rod 5201 is connected to the avoidance cylinder 51. The avoidance cylinder 51, the avoidance spring 5203 and the shock-absorbing spring 5204 are used in combination. When working, the avoidance spring 5203 and the shock-absorbing spring 5204 work to ensure stable working force. When not working, the cylinder avoids the avoidance, so as to avoid unstable product quality caused by unstable air pressure.

[0035] Reference Figure 7 The inner cavity of the fixed frame 5 is rotatably fitted with a stud 53, one end of which passes through the fixed frame 5. The inner cavity of the cross frame 4 is fixedly fitted with a first threaded sleeve 54, one end of which passes through the vertical frame 3 and is slidably connected to the inner cavity of the vertical frame 3. One end of the stud 53 is threadedly connected to the inside of the first threaded sleeve 54. By rotating the stud 53, the stud 53 drives the first threaded sleeve 54 to move laterally, so that the first threaded sleeve 54 drives the cross frame 4 to move simultaneously, thereby adjusting the position of the cross frame 4.

[0036] Reference Figure 7The adjusting assembly 6 includes several adjusting frames 61, which are respectively fixedly installed on the surfaces of six cross frames 4. A second threaded sleeve 62 is rotatably fitted inside each adjusting frame 61, with one end of the second threaded sleeve 62 penetrating through the adjusting frame 61. A screw 63 is threaded inside the second threaded sleeve 62, with one end of the screw 63 penetrating through the second threaded sleeve 62. A second bracket 64 is fixedly connected to one end of the screw 63. A first side support plate 7, a second side support plate 71, a third side support plate 72, a first cross support plate 8, a second cross support plate 81, and a third cross support plate 82 are respectively rotatably installed on the surfaces of the second brackets 64. Scrapers 65 are fixedly installed on the surfaces of each of the second brackets 64, and the scrapers 65 are respectively connected to the first... Side support plate 7, second side support plate 71, third side support plate 72, first horizontal support plate 8, second horizontal support plate 81, and third horizontal support plate 82 are used in conjunction; the surface of the mounting bracket 9 is fixedly mounted with a first slide rail 66, and the inner cavity of the second bracket 64 is slidably connected to the surface of the first slide rail 66; by rotating the second screw sleeve 62, the second screw sleeve 62 drives the screw 63 to move longitudinally, so that the screw 63 drives the second bracket 64 to move, and the position of the second bracket 64 is stabilized by the first slide rail 66, so that the position of the first side support plate 7, second side support plate 71, third side support plate 72, first horizontal support plate 8, second horizontal support plate 81, or third horizontal support plate 82 can be adjusted by the second bracket 64, thereby adapting to plates of different thicknesses.

[0037] Reference Figure 7 The mounting bracket 9 has a second slide rail 96 fixedly mounted on its surface, and the inner cavity of the blade holder 95 is slidably connected to the surface of the second slide rail 96. By making the inner cavity of the blade holder 95 slidably connected to the surface of the second slide rail 96, the position of the blade holder 95 is effectively stabilized, and the position of the scraper 10 is avoided from being affected by the positional displacement of the blade holder 95.

[0038] Working principle: The position of the support rod 5201 inside the first bracket 5202 is stabilized by the avoidance spring 5203 and the shock-absorbing spring 5204. One end of the support rod 5201 is connected to the avoidance cylinder 51. The avoidance cylinder 51, the avoidance spring 5203, and the shock-absorbing spring 5204 are used in combination. During operation, the avoidance spring 5203 and the shock-absorbing spring 5204 work to ensure stable working force. By rotating the stud 53, the stud 53 drives the first threaded sleeve 54 to move laterally, so that the first threaded sleeve 54 drives the crossbeam 4 to move simultaneously, thereby adjusting the position of the crossbeam 4. By rotating the second threaded sleeve 62, the second threaded sleeve 62 drives the screw rod. 63 moves longitudinally so that screw 63 drives second bracket 64 to move, and stabilizes the position of second bracket 64 through first slide rail 66, so that the position of first side plate 7, second side plate 71, third side plate 72, first horizontal plate 8, second horizontal plate 81 or third horizontal plate 82 can be adjusted through second bracket 64 to adapt to plates of different thicknesses. After adjustment, the scraper 10 to be used is installed on the tool holder 95. Then the position of tool holder 95 is precisely adjusted by servo motor 93 and ball screw 94, and the position of tool holder 95 is stabilized by first slide rail 66, so as to adjust the position of scraper 10 to adjust the scraping amount.

[0039] During the sheet material conveying process, the L-shaped scraping assembly successively contacts the two second horizontal support plates 81 and presses them backward, ensuring that the spring force acts on the side of the sheet material through the second horizontal support plates 81. The sheet material then contacts the two second side support plates 71, and the corresponding upper second side support plate 71 is pressed downward, ensuring that the lower upper pressure spring 102 acts on the bottom of the sheet material through the second side support plate 71. Then, it contacts the second horizontal support plate 81 and presses it backward, ensuring that the spring force acts on the side of the sheet material through the second horizontal support plate 81. Finally, it contacts the left second side support plate 71 and presses the corresponding lower second side support plate 71 upward, ensuring that the upper lower top spring 101 acts on the top of the sheet material through the second side support plate 71. Then, by selecting a rounded scraper 10, the scraper 10 works on the upper and lower edges of the sheet material and discharges the scraped filaments from the filament extraction dust hood 92, thereby stably scraping out the desired product effect.

[0040] In the servo scraping assembly, during the sheet material conveying process, the sheet material contacts one of the third horizontal support plates 82 and is pressed backward, ensuring that the spring force acts on the side of the sheet material through the third horizontal support plate 82. The sheet material then contacts two third side support plates 72, causing the corresponding third side support plates 72 to be pressed downward, ensuring that the upper pressure spring 102 below acts on the underside of the sheet material through the third side support plate 72. Then, the sheet material contacts another third horizontal support plate 82 and is pressed backward, ensuring that the spring force acts on the side of the sheet material through the third horizontal support plate 82, and interacts with the upper left third side support plate 82. The plate 72 contacts and presses the corresponding third side plate 72 upward to ensure that the upper bottom spring 101 acts on the board through the third side plate 72. Then, by selecting the rounded corner scraper 10, the scraper 10 works on the upper and lower edges of the board and discharges the scraped filaments from the filament dust suction hood 92, thereby stably scraping out the desired product effect. During the adjustment of the equipment, the position of the blade holder 95 can be precisely adjusted by the servo motor 93 and the ball screw 94, thereby adjusting the position of the scraper 10 to adjust the scraping amount, so that the equipment can perfectly complete the scraping work.
