Description

Technical Field

[0001] This utility model relates to the field of special equipment manufacturing painting technology, and in particular to a special equipment manufacturing painting device. Background Technology

[0002] Special equipment refers to equipment and facilities that involve life safety and are highly dangerous. Due to their inherent performance and the influence of external factors, once a malfunction occurs, it often causes personal injury and serious property damage. For example, pressure pipelines that use a certain pressure to transport gas or liquid.

[0003] When industrial pressure pipelines are painted as an anti-corrosion layer, the anti-corrosion layer needs to be ground off for inspection. After the inspection, it needs to be repainted for repair. However, traditional painting equipment is large and inconvenient to operate when repainting. It cannot spray the paint into the ground layer well, resulting in paint waste and an uneven paint layer.

[0004] Therefore, in order to address this problem, this utility model proposes a special equipment manufacturing spray painting device. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a special equipment manufacturing spray painting device that can overcome the above problems or at least partially solve the above problems.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] The device includes a housing and a handle fixedly connected to the upper end of the housing. The housing has a feed inlet on its side wall. It also includes a right baffle slidably connected inside the housing, and a left baffle that mates with the right baffle slidably connected inside the housing; and a gear rotatably connected inside the housing, which meshes with the right baffle and the left baffle respectively.

[0008] Preferably, a rotating rod that is rotatably connected to the outer wall of the gear is fixedly connected to the housing, and an adjustment knob is fixedly connected to the other end of the rotating rod.

[0009] Preferably, the right baffle and the left baffle are slidably connected, and the right baffle and the left baffle are driven to slide synchronously in opposite directions by the gear.

[0010] Preferably, a groove is provided on the outer wall of the housing, and two positioning rods are slidably connected inside the groove. The two positioning rods are respectively fixedly connected to the outer walls of the right baffle and the left baffle.

[0011] Preferably, a limiting groove is formed on the surface of the housing, a limiting strip is slidably connected inside the limiting groove, a connecting block is fixedly connected to both ends of the limiting strip, and a scraper is rotatably connected between the two connecting blocks.

[0012] Preferably, a connecting strip is fixedly connected to the outer wall of the housing, and a guide groove is formed on the outer wall of the connecting strip, and the guide groove is slidably connected to the scraper.

[0013] Preferably, the connecting block has a fixing groove inside, a return spring is fixedly connected to the inner wall of the fixing groove, and a limiting block that is slidably connected to the other end of the return spring is fixedly connected to the fixing groove.

[0014] Preferably, a limiting plate is fixedly connected to the outer wall of the housing, and the outer wall of the limiting plate is provided with a toothed groove that cooperates with the limiting block.

[0015] By adopting the above technical solution, this utility model has the following beneficial effects compared with the prior art:

[0016] 1. This special equipment manufactures a painting device. When the rotating rod rotates the adjustment knob, it drives the gear to rotate, thereby causing the right baffle and the left baffle to slide synchronously in opposite directions. This adjusts the size of the discharge port formed between the right and left baffles, thus controlling the size of the painting area and ensuring that the paint is sprayed into the sanding layer effectively.

[0017] 2. This special equipment manufactures a painting device. By pressing down on the connecting block, the limiting strip is controlled to slide downward inside the limiting groove. Under the guidance of the guide groove on the outer wall of the connecting strip, the scraper rotates between the two connecting blocks. At the same time, the elastic force of the sliding return spring pushes the limiting block and the limiting plate to fix the scraper, so that the scraper can scrape the paint layer on the surface of the sprayed sanding layer, making the paint layer smoother.

Detailed Implementation

[0025] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments, so that those skilled in the art can implement it based on the description.

[0026] It should be understood that terms such as “having,” “comprising,” and “including” as used herein do not exclude the presence or addition of one or more other elements or combinations thereof.

[0027] In the description of this invention, the terms "lateral", "longitudinal", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0028] Reference Figures 1-6 The device includes a housing 1 and a handle 2 fixedly connected to the upper end of the housing 1. A feed inlet 3 is provided on the side wall of the housing 1. The device also includes: a right baffle 4, which is slidably connected inside the housing 1. A left baffle 5, which cooperates with the right baffle 4, is slidably connected inside the housing 1. A gear 8 is rotatably connected inside the housing 1. The gear 8 meshes with the right baffle 4 and the left baffle 5 respectively. A rotating rod 9, which is rotatably connected to the outer wall of the gear 8, is fixedly connected to the housing 1. An adjustment knob 10 is fixedly connected to the other end of the rotating rod 9. The right baffle 4 and the left baffle 5 are slidably connected. The gear 8 drives the right baffle 4 and the left baffle 5 to slide synchronously in opposite directions.

[0029] In this invention, the rotating rod 9 drives the gear 8 to rotate when the adjustment knob 10 is turned, thereby causing the right baffle 4 and the left baffle 5 to slide in opposite directions. This gradually increases the size of the outlet formed between the right baffle 4 and the left baffle 5, allowing for painting of a larger area of ​​the sanding layer. Conversely, when painting a smaller area of ​​the sanding layer is required, the adjustment knob 10 is turned in the opposite direction, causing the gear 8 to drive the right baffle 4 and the left baffle 5 to slide towards each other. This gradually decreases the size of the outlet formed between the right baffle 4 and the left baffle 5, allowing for painting of a smaller area of ​​the sanding layer. Therefore, the size of the outlet formed between the right baffle 4 and the left baffle 5 can be adjusted by rotating the adjustment knob 10 to control the size of the painting area, facilitating the spraying of paint onto the sanding layer.

[0030] Reference Figures 1-6 Furthermore, a groove 6 is provided on the outer wall of the housing 1, and two positioning rods 7 are slidably connected inside the groove 6. The two positioning rods 7 are fixedly connected to the outer walls of the right baffle 4 and the left baffle 5 respectively. When the right baffle 4 and the left baffle 5 slide, the size of the discharge port can be easily controlled by the position of the two positioning rods 7. At the same time, the positioning rods 7 can be used to position the entire device before spraying, and the spraying operation can be performed in a different position.

[0031] Reference Figures 1-6 Furthermore, a limiting groove 11 is formed on the surface of the housing 1, and a limiting strip 12 is slidably connected inside the limiting groove 11. Connecting blocks 13 are fixedly connected to both ends of the limiting strip 12, and a scraper 14 is rotatably connected between the two connecting blocks 13. A connecting strip 15 is fixedly connected to the outer wall of the housing 1, and a guide groove 16 is formed on the outer wall of the connecting strip 15. The guide groove 16 is slidably connected to the scraper 14. A fixing groove 18 is formed inside the connecting block 13, and a return spring 19 is fixedly connected to the inner wall of the fixing groove 18. A limiting block 20 that is slidably connected to the fixing groove 18 is fixedly connected to the other end of the return spring 19. A limiting plate 17 is fixedly connected to the outer wall of the housing 1, and a toothed groove that mates with the limiting block 20 is formed on the outer wall of the limiting plate 17.

[0032] By pressing down on the connecting block 13, the limiting strip 12 slides downward inside the limiting groove 11, causing the scraper 14 to rotate between the two connecting blocks 13 under the guidance of the guide groove 16 on the outer wall of the connecting strip 15. At the same time, the elastic force of the sliding return spring 19 pushes the limiting block 20 to cooperate with the limiting plate 17 to fix the scraper 14, so that the scraper 14 can scrape the paint layer on the surface of the sprayed sanding layer, making the paint layer smoother.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
