Description

Technical Field

[0001] This utility model relates to the field of paint production technology, and in particular to a paint scraping device. Background Technology

[0002] Paint production is a crucial step in the chemical manufacturing industry, widely used in construction, automotive, furniture, and many other sectors. In the paint production process, paint containers, as key vessels for storing and transporting paint, directly impact the quality and purity of subsequent batches of paint. Especially after paint filling, these containers typically require cleaning and scraping before reuse. Therefore, efficiently removing residue from the inner walls of paint containers is a significant technical challenge for improving paint production efficiency and environmental protection. Paint scraping equipment plays a vital role in the paint processing industry. As a key component in the paint container recycling process, its performance and operation methods have a decisive impact on scraping efficiency, cleanliness, and subsequent safety. Particularly in the core process of scraping the inner walls of paint containers, existing scraping equipment has gradually revealed a series of significant limitations and technical problems when handling paint containers of different sizes, shapes, or materials.

A sliding groove is provided inside the limiting plate, and a fixed rod is slidably connected inside the sliding groove. A support frame is fixedly connected to the top wall of the base plate. In this utility model, paint is injected into the paint bucket through the spray gun, realizing automatic filling of the equipment. A pressing block is provided below the cylinder. After the lid is placed on the filled paint bucket, when the bucket moves under the cylinder, the pressing block presses it down, thereby realizing the automatic capping function of the equipment.

[0004] However, in existing technologies, it is inconvenient to scrape the inner walls of paint cans of different sizes during subsequent reuse, which significantly affects the subsequent use of the paint cans. Specifically, existing scraping equipment faces prominent problems in practical applications, such as inconvenient operation, low efficiency, and unstable cleaning effects. These problems directly lead to reduced scraping efficiency, frequent manual intervention, and the risk of cross-contamination from paint residue, and are difficult to meet the production needs of modern large-scale, continuous cleaning of paint cans of various sizes. Therefore, in response to the many shortcomings of existing technologies, we urgently need an innovative paint production scraping equipment to solve these problems. Utility Model Content

[0005] The purpose of this utility model is to provide a paint scraping device that solves the problem in the prior art where it is inconvenient to scrape the inner wall of paint buckets of different sizes during the subsequent reuse of paint carrier buckets, which greatly affects the subsequent use of paint carrier buckets.

[0006] To achieve the above objectives, this utility model provides a paint production scraping device, including a bearing plate, a support plate rotatably connected to the bottom of the bearing plate, and a first motor fixedly connected to one side of the top of the bearing plate by bolts; A rotating rod is fixedly connected to the top side of the support plate, and the top end of the rotating rod passes through the bearing plate and is connected to the output shaft of the first motor.

[0020] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0021] Please see Figure 1-5 A paint production scraping device includes a support plate 1, a support plate 5 rotatably connected to the bottom of the support plate 1, and a first motor 3 fixedly connected to one side of the top of the support plate 1 by bolts. A rotating rod 4 is fixedly connected to the top side of the support plate 5, and the top end of the rotating rod 4 passes through the bearing plate 1 and is connected to the output shaft of the first motor 3. A scraper 9 is slidably connected to the bottom side of the support plate 5, and a scraping frame 10 is sleeved on the scraper 9. A side frame 13 is fixedly connected to one side of the bearing plate 1, and a screw 14 is rotatably connected to the inner side of the side frame 13. One end of the screw 14 is connected to a nut seat 15 by a threaded connection. A connecting rod 17 is rotatably connected to one side of the nut seat 15 by a pin. One end of the connecting rod 17 is fixedly connected to a locking block 20 that is used with the locking seat 11. A second motor 16 is fixedly connected to the bottom side of the side frame 13 by bolts, and the bottom end of the screw 14 passes through the bottom of the side frame 13 and is connected to the output shaft of the second motor 16.

[0022] When scraping the inner wall of a paint bucket, firstly, install the support plate 1 at the top edge of the paint bucket to be cleaned, ensuring its horizontal stability. Then, the operator slides the scraper 9 connected to the bottom side of the support plate 5 according to the diameter of the paint bucket, and adjusts the relative position of the scraping frame 10 on the scraper 9 so that one side of the scraper 9 can tightly adhere to the inner wall surface of the paint bucket. After the position adjustment is completed, start the first motor 3. The first motor 3 drives the rotating rod 4 to rotate through the output shaft. The rotating rod 4 further drives the support plate 5, which is fixedly connected to its top, to rotate synchronously, thereby driving the scraper 9 to make a circular motion around the center of the paint bucket, effectively scraping and removing residual paint from the inner wall of the paint bucket. During the scraping process, the scraper 9 and the inner wall of the paint bucket... The friction generated between the walls effectively removes the sticky paint layer and hardened residue adhering to the inner wall, improving cleaning efficiency. After the scraping operation is completed, the support plate 1 is removed from the top of the paint bucket, and then the connecting rod 17 is moved so that one end of it engages with the scraping frame 10. At this time, the second motor 16 is started, which drives the screw 14 to rotate. The screw 14 and the nut seat 15 are connected by a threaded engagement, so that the nut seat 15 moves linearly back and forth along the length of the screw 14, and drives the connecting rod 17 and the connected scraping frame 10 to move up and down through the pin shaft, thereby automatically cleaning the paint residue on the surface of the scraper 9, avoiding the inconvenience of manual wiping and the problem of secondary pollution, and preparing for the subsequent use of the scraper 9.

[0023] Furthermore, a slider 6 is fixedly connected to the top of the scraper 9, and the slider 6 is slidably connected to the support plate 5 through the slide groove 7. In the process of adjusting the position of the scraper 9 to adapt to paint buckets of different diameters, the slider 6 slides linearly along the direction of the slide groove 7, making the movement of the scraper 9 on the support plate 5 more stable and smooth, thereby improving the positioning accuracy and operation convenience of the scraper 9, and achieving the effect of improving the equipment's adaptability to paint buckets of different specifications.

[0024] Furthermore, an electric cylinder 8 is fixedly connected to one side of the outer wall of the support plate 5 by bolts, and the output shaft of the electric cylinder 8 passes through the side wall of the support plate 5 and is fixedly connected to one side of the slider 6. During the scraping process, the electric cylinder 8 can automatically adjust the output pressure according to the actual scraping resistance, push the slider 6 to drive the scraper 9 to make slight adjustments inward or outward, and ensure that the scraper 9 is always in close contact with the inner wall of the paint bucket, avoiding poor contact problems caused by bucket deformation or installation errors, thereby improving the continuity and cleaning efficiency of the scraping process.

[0025] Furthermore, one side of the scraper frame 10 is provided with a threaded rod 12, and one end of the threaded rod 12 passes through the threaded groove through one side of the scraper frame 10 and the side wall of the scraper 9. After the scraper 9 is adjusted to fit against the inner wall of the paint bucket, the threaded rod 12 can be rotated to lock it onto the scraper 9, thereby achieving a stable connection between the scraper frame 10 and the scraper 9. This prevents loosening and falling off during high-speed rotating scraping, enhances the overall stability and safety of the structure, and also facilitates quick disassembly and replacement of the scraper frame 10, improving maintenance efficiency.

[0026] Furthermore, mounting plates 2 are fixedly connected to both sides of the bearing plate 1, and the top end of the rotating rod 4 passes through the bearing plate 1 through a bearing sleeve. The top end of the screw 14 is rotatably connected to the top inner side of the side frame 13 through a rotating shaft, and the bottom end of the screw 14 passes through the bottom of the side frame 13 through a bearing sleeve. This structural design not only improves the connection accuracy and rotational stability between the rotating rod 4 and the bearing plate 1, and between the screw 14 and the side frame 13, but also effectively reduces frictional loss during operation and extends the service life of the equipment. At the same time, the presence of the mounting plates 2 provides a more stable installation foundation for the bearing plate 1, improving the overall structural strength and operational stability of the equipment.

[0027] Furthermore, a sliding block 18 is fixedly connected to one side of the nut seat 15, and the sliding block 18 is slidably connected to the side wall of the side frame 13 through the sliding groove 19. When the second motor 16 drives the screw 14 to rotate and drive the nut seat 15 to move up and down, the sliding block 18 performs synchronous guiding motion along the sliding groove 19, effectively preventing the nut seat 15 from shifting or getting stuck during the movement, thereby ensuring that the vertical reciprocating motion of the connecting rod 17 and the scraper frame 10 is more stable and reliable, and further improving the stability and execution accuracy of the self-cleaning process of the scraper 9.

[0028] In summary: When scraping the inner wall of a paint bucket, firstly, the support plate 1 is installed on the top edge of the paint bucket to be cleaned via the mounting plate 2, ensuring its horizontal stability. Then, the operator slides the scraper 9 connected to the bottom side of the support plate 5 according to the diameter of the paint bucket, so that one side of the scraper 9 can tightly adhere to the inner wall surface of the paint bucket. At this time, the slider 6 fixedly connected to the top of the scraper 9 slides linearly along the groove 7, improving stability and positioning accuracy during movement. Simultaneously, an electric cylinder 8 is bolted to one side of the outer wall of the support plate 5, its output shaft passing through the side wall of the support plate 5 and fixedly connected to one side of the slider 6. During the scraping process, the electric cylinder 8 can adjust the output shaft according to the actual situation. The automatic adjustment of output pressure based on scraping resistance pushes slider 6 to slightly adjust scraper 9 inward or outward, ensuring that scraper 9 always remains in close contact with the inner wall of the paint bucket, avoiding poor contact due to bucket deformation or installation errors. After position adjustment, the first motor 3 is started. The first motor 3 drives rotating rod 4 to rotate via output shaft. The top of rotating rod 4 passes through bearing sleeve through bearing plate 1 and is connected to the top of support plate 5, thereby driving support plate 5 and scraper 9 at its bottom to rotate synchronously. This drives scraper 9 to make a circular motion around the center of the paint bucket, effectively scraping and removing residual paint from the inner wall of the paint bucket. The friction between scraper 9 and the inner wall of the paint bucket effectively removes the sticky paint layer and solid residue adhering to the inner wall. To remove residue and improve cleaning efficiency, after the scraping operation is completed, the support plate 1 is removed from the top of the paint bucket. Then, the connecting rod 17 is moved so that one end of it engages with the scraping frame 10. The scraping frame 10 has a threaded rod 12 on one side. One end of the threaded rod 12 passes through the side wall of the scraping frame 10 and the scraper 9 through a threaded groove. By rotating the threaded rod 12, it can be locked onto the scraper 9, achieving a stable connection between the scraping frame 10 and the scraper 9 and preventing loosening and falling off during high-speed rotation. At this time, the second motor 16 is started, which drives the screw 14 to rotate. The top end of the screw 14 is rotatably connected to the top of the inner side of the side frame 13 through a rotating shaft, and the bottom end passes through the side frame 13 through a bearing sleeve. The bottom of frame 13 ensures the smooth operation of screw 14. Screw 14 and nut seat 15 are connected by a threaded fit, allowing nut seat 15 to reciprocate linearly along the length of screw 14. A sliding block 18 is also fixedly connected to one side of nut seat 15. The sliding block 18 is slidably connected to the side wall of side frame 13 through sliding groove 19, effectively preventing nut seat 15 from shifting or getting stuck during movement. At the same time, nut seat 15 drives connecting rod 17 and its connected scraping frame 10 to move up and down through pin, thereby automatically cleaning the paint residue on the surface of scraper 9, avoiding the inconvenience and secondary pollution caused by manual wiping, and preparing for the subsequent use of scraper 9.Through the sliding cooperation structure design of the scraper 9, slider 6, and groove 7, rapid adaptation to various sizes of paint buckets is achieved. Users only need to slide the scraper 9 to match buckets of different sizes, without replacing the entire set of equipment or performing complex adjustments, greatly improving the equipment's versatility and applicability. Secondly, to solve the problems of "inconvenient operation and low efficiency," this utility model introduces a linkage structure between the first motor 3 and the rotating rod 4, combined with the adaptive adjustment function of the accumulator cylinder 8, realizing automated and intelligent control of the scraping process. This not only improves work efficiency but also reduces labor intensity, reduces the risk of operators directly contacting paint residue, and improves operational safety. Thirdly, addressing the problem of "unstable cleaning effect," a vertical guide mechanism consisting of a second motor 16, screw 14, nut seat 15, sliding block 18, and sliding groove 19, and a scraper 9 self-cleaning system consisting of connecting rod 17 and scraper frame 10 are added. This achieves automated cleaning of the scraper 9, solving the problem that traditional methods cannot completely remove residue from the surface of the scraper 9, effectively extending the service life of the scraper 9, and reducing the risk of cross-contamination. Furthermore, the threaded connection between the scraper frame 10 and the scraper 9 via the threaded rod 12 enhances the stability of the connection and the ease of assembly and disassembly, further improving maintenance efficiency. The mounting plates 2 on both sides of the bearing plate 1, as well as the bearing sleeves and shaft structures between the rotating rod 4 and the bearing plate 1, and between the screw 14 and the side frame 13, together constitute a high-precision, low-wear transmission system, effectively improving the overall structural strength, operational stability, and service life of the equipment. In summary, this paint scraping equipment surpasses existing technologies in terms of adaptability, automation, cleaning efficiency, ease of operation, and durability, better meeting the actual needs of modern paint production enterprises for efficient, environmentally friendly, and intelligent scraping equipment.
