[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 protection scope of the present utility model.

[0023] The following is in conjunction with the appendix Figures 1 to 5 The specific embodiments of this utility model will be described in further detail.

[0024] Depend on Figures 1 to 5 As shown, this utility model includes a first fixing block 1 and a second fixing block 2 that can move up and down relative to the first fixing block 1. In order to reduce the probability of tripping during the scraping process, a rotating block 3 that can rotate unidirectionally is provided on the lower side of the second fixing block 2. Two inclined air passages 4 for cleaning the scraped wire are provided on the upper side of the first fixing block 1. The inclined air passages 4 are inclined relative to the upper surface of the first fixing block 1.

[0025] It should be noted that this device is installed in the edge banding machine of the woodworking machinery and furniture industry. Between the edge scraping process and the polishing process, the first fixed block 1 and the rotating block 3 pass through the wood board after the edge scraping operation. The rotating block 3 and the first fixed block 1 cooperate to clamp and remove the scraping wires remaining on the edge of the wood board, so as to reduce the impact of scraping wires during the polishing process. The inclined air channel 4 is connected to a high-pressure air source, which can blow away the scraping wires clamped on the upper side of the first fixed block 1.

[0026] In use, the up-and-down movement of the second fixed block 2 drives the up-and-down movement of the rotating block 3, thereby enabling the rotating block 3 to cooperate with the first fixed block 1 to clamp the scraper. By allowing the rotating block 3 to rotate back and forth relative to the second fixed block 2, when the rotating block 3 contacts the wooden board, the rotating block 3 will rotate relative to the second fixed block 2, thereby effectively reducing the probability of tripping. After clamping the scraper, the high-pressure gas sprayed from the inclined air passage 4 can blow away the scraper.

[0027] Furthermore, by Figures 1 to 5As shown, to facilitate the installation of the device, a first fixing frame 5 is provided on the lower side of the first fixing block 1, and the upper side of the first fixing frame 5 is fixedly connected to the first fixing block 1. A second fixing frame 6 is provided on the upper side of the second fixing block 2, and a cylinder 7 is fixedly connected to the side of the second fixing frame 6. The upper part of the second fixing block 2 is fixedly connected to the moving end of the cylinder 7. The cylinder 7 is existing technology, which is connected to a high-pressure air source and can drive the moving end of the cylinder 7 to move. The stroke of the moving end of the cylinder 7 can be adjusted. It will not be described in detail here.

[0028] In use, the first fixed frame 5 and the second fixed frame 6 are both fixedly connected to the pressure beam body of the edge banding machine. That is, the first fixed frame 5 and the second fixed frame 6 are fixed parts in this device, used to support and fix other parts. The first fixed frame 5 and the first fixed block 1, and the second fixed frame 6 and the cylinder 7 are all connected by bolts. The upper side of the second fixed block 2 is connected to the moving end of the cylinder 7 by bolts.

[0029] Furthermore, by Figures 1 to 5 As shown, in order to enable the rotating block 3 to automatically reset, a connecting block 8 is fixedly connected to the lower side of the second fixed block 2. A placement groove 9 is provided inside the connecting block 8, and a torsion spring 10 is provided inside the placement groove 9. The upper and lower ends of the torsion spring 10 are respectively connected to the second fixed block 2 and the rotating block 3.

[0030] In use, by setting the torsion spring 10, the rotating block 3 can automatically reset after rotating relative to the second fixed block 2, which can apply a suitable cleaning force to the scraper and facilitate repeated cleaning.

[0031] Furthermore, by Figures 1 to 5 As shown, in order to better remove the filaments, a limiting groove 11 is provided on the lower side of the connecting block 8. The limiting groove 11 and the lower part of the torsion spring 10 cooperate with each other to form a structure in which the rotating block 3 rotates in one direction.

[0032] Furthermore, by Figures 1 to 5 As shown, in order to reduce wear on the device and facilitate the replacement of vulnerable parts by the staff, a first gasket 12 is provided between the rotating block 3 and the connecting block 8. The first gasket 12 is detachably connected to the rotating block 3. The first gasket 12 and the rotating block 3 are detachably connected by bolts.

[0033] Furthermore, by Figures 1 to 5As shown, to facilitate assembly by workers, a first mounting groove 13 is provided on the upper side of the rotating block 3, a second mounting groove 14 is provided inside the placement groove 9, and a through groove 15 adapted to the first mounting groove 13 is provided in the middle of the first gasket 12. The upper and lower ends of the torsion spring 10 are connected to the second mounting groove 14 and the first mounting groove 13, respectively. The first mounting groove 13 is an oblong groove, and the cross-section of the second mounting groove 14 is circular. The upper moving end of the torsion spring 10 directly engages with the second mounting groove 14, and the lower moving end of the torsion spring 10 passes through the through groove 15 and engages with the first mounting groove 13. The lower moving end of the torsion spring 10 abuts against the side wall of the limiting groove 11, so that the lower moving end of the torsion spring 10 is limited by the limiting groove 11, thereby allowing the rotating block 3 to only reciprocate in one direction relative to the second fixed block 2.

[0034] Furthermore, by Figures 1 to 5 As shown, in order to increase the stability of the device during operation, a first rotating hole 16 is provided in the middle of the first pad 12, a second rotating hole 17 is provided in the middle of the rotating block 3, the upper side of the first rotating hole 16 is connected to the lower side of the placement groove 9, a friction sleeve 18 is provided inside the torsion spring 10, and a second pad 19 is provided on the lower side of the friction sleeve 18 that abuts against the lower side of the first pad 12.

[0035] In use, the torsion spring 10 is placed inside the placement groove 9, and the friction sleeve 18 is placed inside the torsion spring 10. The torsion spring 10 is confined in the placement groove 9. The lower side plane of the torsion spring 10 abuts against the upper side of the first washer 12. The inner diameter of the first rotating hole 16 is smaller than the inner diameter of the second rotating hole 17. Therefore, the second washer 19 is confined in the second rotating hole 17. When installing the device, the bolt can pass through the middle of the second washer 19 and the middle of the friction sleeve 18, so that the threaded end of the bolt is threadedly connected to the upper side wall of the placement groove 9. At this time, the rotating block 3 and the connecting block 8 are connected by the bolt. Under the action of the second washer 19, the bolt can also serve as the rotating shaft between the rotating block 3 and the connecting block 8.

[0036] By setting the first shim 12, the friction at the bottom of the second fixing block 2 can be reduced, making the device run more stably. During the use of the device, each component can also be disassembled and replaced. The friction sleeve 18 is made of PP material, which can effectively center the torsion spring 10 and reduce the probability of the torsion spring 10 shifting, thus reducing the noise generated when the torsion spring 10 rotates.

[0037] Furthermore, by Figures 1 to 5 As shown, in order to facilitate the removal of scraped wire, a connecting air passage 20 is provided inside the first fixing block 1, and one end of each inclined air passage 4 is connected to the connecting air passage 20.

[0038] It should be noted that a high-pressure air source is connected to the end of the connecting airway 20, and the air source is controlled by a solenoid valve.

[0039] In use, the excess sealing tape is cut off by controlling the vertical movement of the piston in cylinder 7. The rotating plate and the first fixing block 1 are made of PP material, which is high in strength, high in temperature resistance, and lightweight. The first fixing block 1 is equipped with an air blowing function. After the excess broken wire is clamped off, the air blowing is controlled by a solenoid valve. By adjusting the angle of the inclined air passage 4, the broken wire can be accurately blown off, preventing the scraped wire from entering the next working part.

[0040] When this utility model is in use, the second fixed block 2 moves up and down, driving the rotating block 3 to move up and down, thereby enabling the rotating block 3 to cooperate with the first fixed block 1 to clamp the scraper. By allowing the rotating block 3 to rotate back and forth relative to the second fixed block 2, when the rotating block 3 contacts the wooden board, the rotating block 3 will rotate relative to the second fixed block 2, thereby effectively reducing the probability of tripping. After clamping the scraper, the high-pressure gas sprayed from the inclined air passage 4 can blow away the scraper.

[0041] This utility model has a novel structure, ingenious design, and simple and convenient operation. This design effectively reduces the probability of tripping during the scraping process, facilitates the installation of the device, enables the rotating block to automatically reset, achieves better scraping and cleaning results, facilitates the assembly of the device by the staff, increases the stability of the device during operation, and facilitates the removal of scraped wire.

[0042] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
