Description

Technical Field

[0001] This utility model belongs to the field of paint production, and more specifically, it relates to a paint scraping device for paint production. Background Technology

[0002] Paint production is an industrial process that uses resins, pigments, fillers, and solvents as raw materials, mixing and reacting them through automated production lines to create coating materials with specific functions. Currently, because paints themselves have a certain viscosity and adhesion, after the paint is mixed and stirred in the mixing tank, some paint components will stick and accumulate on the inner wall of the mixing tank. To prevent the residual paint from remaining in the tank for a long time and causing it to solidify and deteriorate, and to ensure the production quality of the next batch of paints with different formulations or colors in the same mixing tank, it is usually necessary to use a scraper from a scraping device to scrape and remove the paint from the inner wall of the mixing tank. However, because the scraper holder structure of traditional paint scraping equipment is fixed and cannot be adjusted, the wear caused by the friction between the scraper and the inner wall of the mixing tank causes the scraper to gradually detach from the inner wall of the mixing tank, which seriously affects the scraping quality and efficiency of the scraper on the inner wall of the mixing tank. Utility Model Content

[0003] To address the aforementioned technical problems, this utility model provides a paint scraping device for paint production, which solves the problem of reduced paint scraping quality caused by the fixed and non-adjustable scraper holder structure of traditional paint scraping devices, which leads to scraper wear and detachment from the inner wall of the mixing cylinder.

[0004] This utility model provides a paint scraping device for paint production, including a handrail frame; a pressure cylinder is welded to the inner side of the handrail frame; it also includes a cover plate, a double-threaded rod, and a threaded rotating rod; a cover frame is bolted to the outer side of the cover plate, a through hole is provided at the center of the cover frame, a rotating frame is rotatably connected to the through hole of the cover frame, a scraping motor is installed on the upper side of the cover plate, a drive gear is installed on the motor shaft of the scraping motor, and a control unit is installed on the upper side of the cover plate; an adjustment knob is welded to the center of the double-threaded rod, and a telescopic frame is meshed with the outer side of the double-threaded rod; a lifting knob is welded to the top of the threaded rotating rod, a lifting bracket is rotatably connected to the outer side of the threaded rotating rod, and a scraper is installed on the lifting bracket.

[0005] Furthermore, the upper and lower sides of the rotating frame are provided with circular grooves, and the inner wall of the circular groove of the rotating frame is provided with an internal tooth structure, and the drive gear is meshed with the internal tooth structure of the rotating frame.

[0006] Furthermore, the upper side of the cover frame is provided with six sets of through slots, which are arranged in a circular array around the vertical central axis of the cover frame. Each set of through slots of the cover frame is inserted with a clamp plate, and the clamp plate is provided with two sets of through holes. A guide rod is inserted into the through holes of the clamp plate, and the upper side of the clamp plate is provided with a sloping structure.

[0007] Furthermore, the telescopic frame consists of two sets, symmetrically distributed on the left and right sides. Each set of telescopic frames has an L-shaped structure, and each set of telescopic frames has a long through groove on its L-shaped structure. The opposite surfaces of the two sets of telescopic frames are provided with threaded deep holes. The threaded deep hole of the left telescopic frame is engaged with the forward thread end of the bidirectional threaded rod, and the threaded deep hole of the right telescopic frame is engaged with the reverse thread end of the bidirectional threaded rod.

[0008] Furthermore, the lifting bracket has a protruding plate on its outer side near the top, which is embedded in the long through groove of the telescopic frame. The center of the upper side of the protruding plate of the lifting bracket is provided with a threaded through hole, and a threaded rotating rod is engaged in the threaded through hole of the protruding plate of each set of lifting brackets.

[0009] Furthermore, the outer side of the pressure cylinder is provided with a threaded structure near the bottom end, and the threaded connection of the outer side of the pressure cylinder is engaged with the threaded structure on the inner side of the cover frame.

[0010] Compared with the prior art, the present invention has the following beneficial effects: 1. In this utility model, the threaded transmission mechanism, formed by the engagement of the forward and reverse threaded ends of the bidirectional threaded rod in the deep threaded holes of two sets of telescopic frames, causes the symmetrical L-shaped telescopic frames to move in opposite directions along the rectangular through slot of the cover frame. This pushes the scraper on the lifting bracket closer to the cylinder wall, achieving scraper wear adjustment and compensation, ensuring that the scraper is always in close contact with the cylinder wall. This ensures that each scraping operation can remove residual paint, guaranteeing that the quality of the next batch of paint production is not contaminated, and improving the scraping quality of the scraper on the inner wall of the mixing cylinder.

[0022] In this embodiment of the utility model, the upper and lower sides of the rotating frame 7 are provided with circular grooves. The inner wall of the circular groove of the rotating frame 7 is provided with an internal tooth structure. The drive gear 8 is meshed and connected to the internal tooth structure of the rotating frame 7. During the process of the scraping motor 4 driving the drive gear 8 to rotate, the drive gear 8 drives the rotating frame 7 meshed and connected to the outer side to rotate. The rotating frame 7 then drives the telescopic frame 13 inserted in the rectangular through groove to rotate around the vertical central axis of the rotating frame 7, thus completing the rotating scraping and cleaning work of the scraper 14 on the inner wall of the mixing tank.

[0023] In this embodiment of the present invention, the upper side of the cover frame 6 is provided with six sets of through slots, which are arranged in a circular array around the vertical central axis of the cover frame 6. Each set of through slots of the cover frame 6 is provided with a clamping plate 10, which is provided with two sets of through holes. A guide rod 11 is inserted into the through holes of the clamping plate 10. The upper side of the clamping plate 10 is provided with a sloping structure. The groove wall of the cover frame 6, together with the guide rod 11, provides directional support for the clamping plate 10, ensuring that the six sets of clamping plates 10 move horizontally and fit against the outer wall of the mixing tank for stable clamping.

[0024] In this embodiment of the utility model, there are two sets of telescopic frames 13, which are symmetrically distributed on the left and right sides. Each set of telescopic frames 13 has an L-shaped structure and a long through groove on the L-shaped structure. The opposite surfaces of the two sets of telescopic frames 13 are provided with threaded deep holes. The threaded deep hole of the left telescopic frame 13 is engaged with the positive thread end of the bidirectional threaded rod 12, and the threaded deep hole of the right telescopic frame 13 is engaged with the reverse thread end of the bidirectional threaded rod 12. During the process of adjusting the knob 5 to drive the bidirectional threaded rod 12 to rotate, the bidirectional threaded rod 12 drives the two sets of telescopic frames 13 to move in opposite directions along the rectangular through groove of the rotating frame 7, so that the telescopic frames 13 drive the scraper 14 installed on the lifting bracket 17 to adjust and fit against the cylinder wall of the mixing tank, compensate for the wear of the scraper 14, and avoid the situation of incomplete scraping due to wear.

[0025] In this embodiment of the present invention, a protruding plate is located on the outer side of the lifting bracket 17 near the top. The protruding plate of the lifting bracket 17 is embedded in the elongated through groove of the telescopic frame 13. A threaded through hole is provided at the center of the upper side of the protruding plate of the lifting bracket 17. A threaded rotating rod 16 is engaged in the threaded through hole of the protruding plate of each set of lifting brackets 17. During the process of the lifting knob 15 driving the threaded rotating rod 16 to rotate, the threaded rotating rod 16 drives the lifting bracket 17 to slide vertically along the elongated through groove of the telescopic frame 13, thereby adjusting the scraping depth area of ​​the scraper 14 on the lifting bracket 17 to the mixing cylinder according to the depth position of the mixing cylinder.

[0026] In this embodiment of the utility model, the outer side of the pressure cylinder 1 is provided with a threaded structure near the bottom. The outer side of the pressure cylinder 1 is threadedly engaged with the threaded structure on the inner side of the cover frame 6. During the rotation of the pressure cylinder 1 driven by the handrail frame 2, the pressure cylinder 1 rotates downward along the threaded structure on the inner side of the cover frame 6, so that the bottom edge of the inner side of the pressure cylinder 1 pushes the inclined structure of the six sets of clamping plates 10, so that the six sets of clamping plates 10 are centripetally centered and fixed on the outer side of the mixing tank, ensuring that the scraper 14 is subjected to uniform force and moves smoothly during the rotation and scraping of the inner wall of the mixing tank.

[0027] Specific usage and function of this utility model embodiment: When installing and scraping the material on the mixing cylinder, the following steps are performed: First, manually rotate the adjusting knob 5. The adjusting knob 5 drives the bidirectional threaded rod 12 to rotate. Since the forward and reverse threaded ends of the outer side of the bidirectional threaded rod 12 are respectively engaged in the deep threaded holes of the two sets of telescopic frames 13, the bidirectional threaded rod 12 drives the two sets of telescopic frames 13 to move left and right in opposite directions along the rectangular through groove of the rotating frame 7 until the two sets of telescopic frames 13 push the scrapers 14 installed on the two sets of lifting brackets 17 to fit against the inner wall of the mixing cylinder. Then, place the cover frame 6 on the upper side of the mixing cylinder and manually rotate the handrail frame 2. The handrail frame 2 drives the pressure cylinder 1, which is welded to the inner side, to rotate. Since the outer side of the pressure cylinder 1... The threaded connection is made at the threaded structure on the inner side of the cover 6. The pressure cylinder 1 rotates downward along the threaded structure on the inner side of the cover 6. The bottom edge of the inner side of the pressure cylinder 1 pushes the inclined structure of the six sets of clamping plates 10, so that the six sets of clamping plates 10 are clamped and fixed in a centripetal center along the guide rod 11 on the outer side of the mixing tank. Then, the control machine 3 controls the scraper motor 4 to start through the wire. The scraper motor 4 drives the drive gear 8 to rotate. Since the drive gear 8 is engaged with the internal tooth structure of the groove on the upper side of the rotating frame 7, the drive gear 8 drives the rotating frame 7 to rotate. The rotating frame 7 drives the telescopic frame 13 inserted in the rectangular through slot to rotate around the vertical central axis of the rotating frame 7, completing the rotating scraping and cleaning work of the scraper 14 on the inner wall of the mixing tank.

[0028] All the above components are installed, connected, or set up using common mechanical methods, such as welding, threaded connections, and screw connections. Furthermore, the specific structure, model, and coefficient indicators of all components are based on their own technologies; any method that achieves the desired effect can be implemented.
