DETAILED DESCRIPTION

[0023] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings, but the embodiments described in the utility model are only part of the embodiments of the utility model, rather than all the embodiments.

[0024] The present application embodiment provides a device for scraping glue from the inner wall of a fish tank, such as Figure 1 and Figure 2 As shown, it includes a moving frame 2 and a base 1. The moving frame 2 is rotatably arranged above the base 1 and is movable in the vertical direction. A gear rack assembly 3 is arranged in the moving frame 2, which includes a driving motor 31 arranged at the center of the top surface or bottom surface inside the moving frame 2. The driving end of the driving motor 31 faces the vertical direction and is connected to a gear 32. The projection of the gear 32 on the base 1 in the vertical direction is located at the center of the base 1. Two parallel racks 33 are meshed on both sides of the gear 32 and are movable in the length direction of the base 1. When the moving frame 2 moves downward to the farthest point in the vertical direction, the rack 33 is aligned with the base 1. There is a predetermined distance between the two racks 33, so that the rack 33 is always located above the opening of the fish tank, so as to avoid interference between the rack 33 and the inner wall of the fish tank when the moving frame 2 rotates; a first door frame 34 is respectively provided on the two racks 33, and both ends of the first door frame 34 are connected to a scraper frame 35 perpendicular to the length direction of the base 1, and there is a predetermined distance between the far end of the scraper frame 35 and the moving frame 2 in the vertical direction. The far end of the scraper frame 35 is telescopically provided with a scraper 36 adapted to the joint between the bottom and the inner wall of the fish tank, and the telescopic direction of the scraper 36 is perpendicular to the length direction of the base. When the scrapers 36 abut against each other, the travel of the rack 33 just starts.

[0025] Specifically, the projection of the gear 32 on the base 1 along the vertical direction is located at the center of the base 1, so that during the scraping process, the stroke lengths of the two scrapers 36 moving in opposite directions are equal; when the moving frame 1 moves upward in the vertical direction until the distance between the scraper 36 and the base 1 is greater than the height of the fish tank, the fish tank is placed on the base. At this time, the length direction of the fish tank is consistent with the length direction of the base 1, and the scraper 36 shrinks toward the far end of the scraping frame 35, and the scrapers 36 are in a state of mutual abutment; the moving frame 1 moves downward in the vertical direction until the scraper 36 reaches a position that can adapt to the seam at the bottom of the fish tank, such as Figure 3 As shown, the scraper 36 extends outward until the scraper 36 is matched with the joints on both sides of the bottom of the fish tank along the length direction; the rack 33 and the gear 32 begin to mesh, driving the scraper 36 that abut against each other to start moving toward each other until the scraper 36 moves to a position that is matched with the joints on the inner wall of the fish tank, at which time the glue at the joints on both sides of the bottom of the fish tank along the length direction is scraped off; the moving frame 2 moves upward in the vertical direction to scrape off the glue at the joints on the inner wall of the fish tank; thereafter, the scraper 36 contracts toward the far end of the scraper frame 35, the rack 33 meshes with the gear 32, so that the scraper 36 returns to a state of abutting against each other, the moving frame 2 rotates ninety degrees around its own axis, and the moving frame 2 moves downward in the vertical direction until the scraper 36 reaches a position that can match the joints on both sides of the bottom of the fish tank along the width direction, as shown in FIG. Figure 2 and Figure 4 As shown, the scraper 36 extends outward until the scraper 36 is matched with the seams on both sides of the bottom of the fish tank along the width direction, and the rack 33 and the gear 32 begin to mesh, driving the scrapers 36 that abut each other to start moving toward each other until the scraper 36 moves to a position matched with the seams on the inner wall of the fish tank. At this time, the glue at the seams on both sides of the bottom of the fish tank along the width direction is scraped off; the moving frame 2 moves upward in the vertical direction to scrape off the glue at the seams on the inner wall of the fish tank. In the above manner, the function of automatically scraping off excess glue at each seam in a large fish tank can be achieved.

[0026] More specifically, in order to make the scraper fit every joint of the fish tank, it is better to scrape off the excess glue, and during the scraping process, the accumulated glue will not overflow from the scraper. Figure 5As shown, the scraper frame 361 is telescopically connected to the far end of the scraper frame 35, and a scraper blade 362 is provided at the bottom of the scraper frame 361. The scraper blade 362 is square, and a glue baffle 363 is provided on one side of the scraper blade 362 and the scraper frame 361. When the moving frame 2 is dropped to a predetermined height in the vertical direction and the scraper 36 is telescoped to a predetermined length, the scraper blade 362 fits the bottom of the fish tank, and the glue baffle 363 abuts against the inner wall of the fish tank, and the scraper frame 361, the scraper blade 362 and the glue baffle 363 form a glue storage space. One side of the scraper blade 362 abuts against the joint along the length direction of the bottom of the fish tank, and the rack 33 meshes with the gear 32, driving the scraper blade 362 to move along the joint, so that the glue at the joint is separated from the bottom of the fish tank, and under the action of the glue baffle 363, the glue separated by the scraper blade 362 is blocked. At the same time, one side of the glue baffle 363 abuts against the inner wall of the fish tank to scrape off the glue on the inner wall of the fish tank joint, and the scraped glue is accumulated on the scraper frame 361, the scraper blade 362 and the glue baffle 363. The scraper 36 continues to move along the length direction of the fish tank until the other side of the scraper blade 362 abuts against the seam at the bottom of the fish tank along the width direction. At this time, the moving frame 2 moves upward in the vertical direction, driving the scraper blade 362 to move upward along the seam between the inner walls of the fish tank, scraping the glue at the seam between the inner walls of the fish tank. The scraped glue accumulates in the glue storage space formed by the scraper frame 361, the scraper blade 362 and the glue baffle 363. The meshing of the gear rack is stable. After the excess glue is scraped off, a flat glue surface can be formed at the seam at the bottom of the fish tank to improve the aesthetics and sealing of the fish tank.

[0027] More specifically, Figure 5 As shown, the distal end face of the scraper frame 35 is vertically inserted with a telescopic rod 351, which is arranged to move along the axis, and the distal end of the telescopic rod 351 is connected to the scraper frame 361. The distal end of the scraper frame 35 is coaxially provided with a linear cylinder 37 with the telescopic rod 351, and the movable end of the linear cylinder 37 is connected to the scraper frame 361. When the moving frame 2 moves downward from the maximum height in the vertical direction, the linear cylinder 37 will drive the scraper 36 to retract toward the distal end face of the scraper frame 35 to avoid motion interference between the scraper 36 and the opening of the fish tank. When the scraper reaches a position that can fit the bottom seam, the linear cylinder 37 drives the scraper 36 to retract outwards so that the scraper 36 abuts against the bottom seam; before the moving frame 2 rotates, the linear cylinder 37 drives the scraper to retract toward the distal end face of the scraper frame 35 to avoid motion interference between the scraper 36 and the inner wall of the fish tank when the moving frame 2 drives the scraper 36 to rotate.

[0028] Specifically, Figure 1 and 2 As shown, a pair of rack seats 21 are arranged parallel to the length direction of the base 1 on the top or bottom surface of the movable frame 2, and the rack 33 is fitted in the rack seat 21, so that the meshing process of the rack 33 and the gear 32 is smoother, thereby making the rubber surface scraped by the scraper 36 smoother and more beautiful.

[0029] Specifically, Figure 1 As shown, a second door frame 11 is mounted on the base 1 along the width direction, and a lifting cylinder 4 is fixedly arranged on the top of the second door frame 11. The movable end of the lifting cylinder 4 is vertically downward and penetrates the top of the second door frame 11 to connect the moving frame 2. The lifting cylinder 4 enables the moving frame 2 to move upward in the vertical direction, so that the scraper 36 can scrape the seams between the inner walls of the fish tank. Compared with other linear mechanisms, the lifting cylinder 4 runs more smoothly and can form a flat rubber surface at the seam.

[0030] More specifically, Figure 1 As shown, a receiving plate 5 is provided between the movable end of the lifting cylinder 4 and the moving frame 2, the lower part of the receiving plate 5 is rotatably connected to the moving frame 2, and its rotation axis is coaxial with the rotation axis of the gear 32, and the upper part of the receiving plate 5 is connected to the movable end of the lifting cylinder 4. A rotating motor or other rotatable mechanism can be provided at the lower part of the receiving plate 5 to realize the function of rotating the moving frame around the rotation axis of the gear 32. The rotating setting of the moving frame 2 around the rotation axis of the gear 32 can make the projection of the gear 32 on the base 1 in the vertical direction be located at the center of the base 1 after the moving frame 2 rotates, so that during the scraping process after the moving frame 2 rotates, the stroke lengths of the two scrapers 36 moving in opposite directions are still equal.

[0031] Specifically, Figure 1 As shown, a pair of positioning blocks 12 are provided on both sides of the base 1 along the length direction. When the fish tank is placed on the base, the corners of the fish tank can cooperate with the positioning blocks 12. After cooperation, the projection of the gear 32 on the base 1 along the vertical direction is located at the center of the base 1, making the positioning operation of the device simple.

[0032] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Obviously, those skilled in the art can make various changes and modifications to the present application without departing from the spirit and scope of the present application.
