The movable base is equipped with a first blocking member and a second blocking member that can move along the direction of movement of the rack. The first blocking member and the second blocking member are both located on the side of the rack away from the gear ring. The first blocking member and the second blocking member are spaced apart along the direction of movement of the rack. The first positioning post and the second positioning post are located between the first blocking member and the second blocking member.

[0008] Furthermore, both the first blocking member and the second blocking member are threadedly connected to the movable seat, and both the first blocking member and the second blocking member are spring pins.

[0009] Furthermore, the rotating shaft is installed on the left or right side of the movable seat, and the movable seat has a first receiving groove and a second receiving groove extending in the front-back direction.

[0022] Reference Figure 1 As shown, the upper scraper mechanism provided in the embodiment of this utility model includes a fixed base 100, a scraper assembly 200, and a first driving device 300; the scraper assembly 200 includes a movable base 210, a scraper 220, and a driving positioning structure 230. The movable base 210 is movably mounted on the fixed base 100, the scraper 220 is rotatably mounted on the movable base 210, and the driving positioning structure 230 is mounted on the movable base 210. The driving positioning structure 230 can drive the scraper 220 to rotate and lock the angle of the scraper 220 relative to the movable base 210; the first driving device 300 is mounted on the fixed base 100 and can drive the movable base 210 to move left and right.

[0023] The first driving device 300 can drive the movable seat 210 to move left and right, and the driving positioning structure 230 can drive the scraper 220 to rotate and lock the angle of the scraper 220 relative to the movable seat 210. Thus, the scraper 220 can adjust its position in the left and right directions and adjust its angle when scraping the excess material according to the shape of the vertical surface 404 on the plate 400, so that the upper scraper mechanism can scrape the plate 400 with different groove 401 shapes.

[0024] like Figure 2 As shown, taking one type of board 400 as an example, the board 400 has a groove 401 on the right side. The groove 401 includes a flat surface 402, a contact surface 403 and an upper vertical surface 404 from bottom to top. The upper vertical surface 404 is located to the left of the right side wall of the board 400. The upper vertical surface 404 includes a first inclined segment 405, a straight segment 406 extending in the front-back direction and a second inclined segment 407 connected from front to back. The first inclined segment 405 and the straight segment 406 and the second inclined segment 407 and the straight segment 406 have an angle greater than 90 degrees.

[0025] The edge banding tape is applied to the flat surface 402, the contact surface 403, and the upper vertical surface 404. Before operation, the first driving device 300 drives the moving seat 210 to move to the left, so that the position of the scraper 220 corresponds to the position of the first inclined section 405 (that is, when the plate 400 passes the scraper 220, the scraper 220 is located above the first inclined section 405). Then, the driving positioning structure 230 drives the scraper 220 to rotate at a certain angle, so that the rear side edge 221 (blade) of the scraper 220 is perpendicular to the first inclined section 405. Subsequently, the driving positioning structure 230 locks the scraper 220, so that the scraper 220 cannot rotate.

[0026] At work, such as Figure 1 As shown, the scraper 220 is placed on top of the board 400, and the conveying device (not shown in the figure) drives the board 400 to move forward. When the board 400 passes the scraper 220, the scraper 220 first scrapes off the excess edge banding at the first inclined section 405 (from point a to point b). Afterwards, with the scraper 220 positioned at point b, the first drive device 300 drives the movable seat 210 to move to the left, and the drive positioning structure 230 again drives the scraper 220 to rotate at a certain angle, such as... Figure 4 As shown, the rear side 221 (blade) of the scraper 220 is perpendicular to the straight section 406, and then the positioning structure 230 is driven to lock the scraper 220 again so that the scraper 220 cannot rotate; the conveying device continues to drive the plate 400 forward, and the scraper 220 scrapes off the excess edge banding at the straight section 406 (from point b to point c); After that, the scraper 220 is located at point c. There are two ways to deal with the excess edge banding at the second inclined section 407: First, keep the rear side 221 (blade) of the scraper 220 perpendicular to the straight section 406 and keep the drive plate 400 moving forward. Drive the scraper 220 to the right through the first drive device 300 to scrape the excess edge banding at the second inclined section 407 (from point c to point d). Second, drive the positioning structure 230 to drive the scraper 220 to rotate at a certain angle so that the rear side 221 (blade) of the scraper 220 is perpendicular to the second inclined section 407. Drive the positioning structure 230 to lock the scraper 220 again. Then, the conveying device continues to drive the plate 400 forward, and the scraper 220 scrapes away the excess edge banding at the second inclined section 407 (from point c to point d).

[0027] As the board 400 moves forward, the scraper 220 scrapes off the excess edge banding at the first inclined section 405, the excess edge banding at the straight section 406, and the excess edge banding at the second inclined section 407 in sequence by rotating and moving.

[0028] Furthermore, such as Figure 1 , 5 As shown, the scraper assembly 200 also includes a rotating shaft 240, which is rotatably mounted on the movable base 210. The scraper 220 is mounted on the rotating shaft 240, and the drive positioning structure 230 can drive the rotating shaft 240 to rotate and lock the rotating shaft 240.

[0029] The rotating shaft 240 drives the scraper 220 to rotate, which facilitates the driving positioning structure 230 to drive the scraper 220 to rotate and facilitates locking the scraper 220. Furthermore, such as Figure 6 As shown, the drive positioning structure 230 includes: Gear ring 231 is sleeved on rotating shaft 240; Rack 232 is movably mounted on movable seat 210, and rack 232 is located on one side of gear ring 231 and meshes with it; The second drive device 233 is mounted on the movable base 210 and connected to the rack 232. The second drive device 233 can drive the rack 232 to move.

[0030] During operation, the second drive device 233 drives the rack 232 to move, and the rack 232 drives the rotating shaft 240 to rotate through the gear ring 231. As a result, the second drive device 233 can drive the scraper 220 to rotate. Since the second drive device 233 no longer drives the rack 232 to move, the rotating shaft 240 is fixed and the scraper 220 cannot rotate.

[0031] Specifically, the second drive device 233 can be a motor, and the motor shaft is threadedly connected to the rack 232. When the motor shaft rotates, the rack 232 moves, and the rack 232 drives the rotating shaft 240 to rotate through the gear ring 231. Since the motor shaft does not rotate, the rotating shaft 240 cannot drive the rack 232 and the shaft to rotate through the gear ring 231, and thus the scraper 220 is fixed.

[0032] Furthermore, such as Figure 5 , 6 As shown, the second drive device 233 is a cylinder. A first positioning post 234 and a second positioning post 235 are installed on the side of the rack 232 away from the gear ring 231. The first positioning post 234 and the second positioning post 235 are spaced apart along the movement direction (front and back direction) of the rack 232. The movable base 210 is equipped with a first blocking member 211 and a second blocking member 212 that can move along the direction of movement (front and back direction) of the rack 232. The first blocking member 211 and the second blocking member 212 are both located on the side of the rack 232 away from the gear ring 231. The first blocking member 211 and the second blocking member 212 are spaced apart along the direction of movement of the rack 232. The first positioning post 234 and the second positioning post 235 are located between the first blocking member 211 and the second blocking member 212.

[0033] By providing a first positioning post 234, a second positioning post 235, a first blocking member 211, and a second blocking member 212, the second driving device 233 can accurately position the angle of rotation of the scraper 220 even though it uses a cylinder to drive the rack 232 to move.

[0034] For example, such as Figure 4 As shown, the initial state of the scraper 220 is that the rear side 221 (blade) of the scraper 220 is perpendicular to the straight section 406; the cylinder retracts to make the second positioning post 235 abut against the second blocking member 212, so that the rear side 221 (blade) of the scraper 220 remains perpendicular to the straight section 406. Since the first blocking member 211 can move back and forth, the position of the first blocking member 211 in the front and back direction can be adjusted according to the situation (so that the rear side 221 of the scraper 220 is perpendicular to the first inclined section 405). After the adjustment is completed, the cylinder extends and drives the rack 232 to move forward. The rack 232 drives the first positioning post 234 to abut against the rear end of the first blocking member 211. At this time, the rear side 221 (blade) of the scraper 220 is perpendicular to the first inclined section 405. That is, the rotation angle of the scraper 220 can be controlled by adjusting the position of the first blocking member 211 and the second blocking member 212 in the front-back direction.

[0035] When it is necessary to scrape off excess material from the aforementioned sheet 400, the first drive device 300 drives the movable seat 210 to move to the left, such as... Figure 3 As shown, the scraper 220 is positioned to correspond with the first inclined section 405, and then the cylinder extends, driving the rack 232 to move forward. At the same time, the rack 232 drives the scraper 220 to rotate through the gear ring 231 and the rotating shaft 240. When the first positioning post 234 on the rack 232 abuts against the rear end of the first blocking member 211, the rear side 221 (blade) of the scraper 220 is perpendicular to the first inclined section 405; the plate 400 moves forward, and the scraper 220 scrapes off the excess edge banding at the first inclined section 405. After scraping, the first drive device 300 drives the moving seat 210 to move to the left, so that the position of the scraper 220 corresponds to the position of the straight section 406. The cylinder retracts, and the cylinder drives the rack 232 to move backward. At the same time, the rack 232 drives the scraper 220 to rotate through the gear ring 231 and the rotating shaft 240. When the second positioning post 235 on the rack 232 abuts against the front end of the second blocking member 212, the rear side 221 (blade) of the scraper 220 is perpendicular to the straight section 406, the plate 400 moves forward, and the scraper 220 scrapes off the excess edge banding at the straight section 406. While the cylinder remains in a retracted state, the first drive device 300 drives the moving seat 210 to move to the right, and the scraper 220 scrapes off the excess sealing tape at the second inclined section 407.

[0036] Furthermore, both the first blocking member 211 and the second blocking member 212 are threadedly connected to the movable seat 210, and both the first blocking member 211 and the second blocking member 212 are spring pins.

[0037] Both blocking components are threadedly connected to the movable seat 210 to facilitate adjustment of the front and rear positions of the two blocking components; the blocking components use spring-loaded pins, so that the rack 232 and the blocking components are in elastic contact, thereby improving the service life of the scraper 220.

[0038] Furthermore, such as Figure 5 , 6 As shown in Figure 7, the rotating shaft 240 is installed on the left or right side of the movable seat 210. The movable seat 210 has a first receiving groove 213 and a second receiving groove 214 extending in the front-back direction. The second receiving groove 214 is located on the side of the first receiving groove 213 away from the rotating shaft 240. The rack 232 can be installed in the first receiving groove 213 in the front-back direction. At least a portion of the first positioning post 234, the second positioning post 235, the first blocking member 211, and the second blocking member 212 are all placed in the second receiving groove 214.

[0039] The first receiving slot 213 and the second receiving slot 214 are provided in the movable seat 210 to facilitate the use of the space inside the movable seat 210.

[0040] Furthermore, such as Figure 5 As shown, there are two second receiving slots 214, which are spaced apart in the front-to-back direction. The first positioning post 234 is located in the front second receiving slot 214, the first blocking member 211 is installed on the front side inside the front second receiving slot 214, the second positioning post 235 is located in the rear second receiving slot 214, and the second blocking member 212 is installed on the rear side inside the rear second receiving slot 214.

[0041] The second receiving slot 214 is provided in two parts to separate the two positioning posts and the two blocking elements.

[0042] Furthermore, the rotating shaft 240 is mounted on the gear ring 231 in a way that allows it to move up and down, so that the scraper 220 can be adjusted in height and can adapt to plates 400 of different thicknesses.

[0043] Specifically, the bottom of the gear ring 231 has a downwardly extending extension tube, and a tube clamp is installed on the outside of the extension tube. The rotating shaft 240 is installed inside the gear ring 231 and the extension tube, and the tube clamp fixes the rotating shaft 240 and the extension tube together.

[0044] Furthermore, such as Figure 1 As shown, the fixed base 100 has a mounting cavity 110, in which a slide rod 120 and a rotatable lead screw 130 are installed. The slide rod 120 is located above and / or below the lead screw 130. The movable base 210 is located in the mounting cavity 110 and is mounted on the slide rod 120 in a way that allows it to move left and right. The movable base 210 is threadedly connected to the lead screw 130. The first drive device 300 is a servo motor, and the shaft of the servo motor is fixedly connected to the lead screw 130.

[0045] The moving seat 210 is driven by a servo motor and lead screw 130 to precisely control the position of the scraper 220 in the left and right directions.

[0046] Furthermore, such as Figure 1 , 5 As shown, the bottom of the rotating shaft 240 has a positioning plate 241, and a scraper 220 is provided on one side of the positioning plate 241. By providing the positioning plate 241, the scraper 220 can be positioned in the vertical direction.

[0047] During operation, the positioning plate 241 abuts against the top of the plate 400, the plate 400 moves forward, and the scraper 220 scrapes off the excess edge banding at the top of the plate 400.

[0048] It is understandable that the lower end of the scraper 220 is at the same height as the lower end of the positioning plate 241, but the lower end of the scraper 220 is higher than the lower end of the positioning plate 241.
