Description

Technical Field

[0001] This utility model relates to the field of spray painting technology, specifically a spray painting device for pencil production. Background Technology

[0002] One of the primary purposes of pencil spray painting is to make pencils more visually appealing. Spray painting allows for the addition of various colors to meet the aesthetic needs of different consumers. For example, pencils designed for elementary school students might be sprayed with bright colors such as red, green, and blue. Simultaneously, the paint forms a protective film on the pencil's surface, protecting the wooden parts from environmental damage. Wooden pencils are easily affected by changes in moisture and humidity; spray painting effectively prevents them from warping or molding due to dampness. Furthermore, this protective film reduces wear and tear during use, extending the pencil's lifespan.

[0003] Current pencil spray painting equipment requires the pencil to be fixed during spray painting, which may result in some areas of the pencil's side wall not being covered, creating blind spots. In addition, if the speed of the conveyor belt transporting the pencil is unstable, the pencil may stay in the spraying area for an inconsistent amount of time, resulting in uneven paint thickness on the pencil's side wall.

[0004] Therefore, it is necessary to improve the existing technology to solve the above-mentioned technical problems. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-5In this embodiment of the present invention, a pencil production spray painting device includes a housing 100. Spray nozzles 200 are uniformly arranged and fixedly installed on the front end of the inner wall of the housing 100. The front end of the outer wall of all spray nozzles 200 penetrates the front end of the outer wall of the housing 100 and is fixedly installed with a connecting pipe 210. A sliding frame 300 is fixedly connected to the right side of the outer wall of the housing 100. A sliding strip 310 is slidably connected inside the sliding frame 300. A sliding rod 400 is linearly arranged and slidably connected to the rear end of the inner wall of the housing 100. A clamping strip 410 is fixedly installed on the front end of the outer wall of all sliding rods 400. A connecting post 500 is linearly arranged and fixedly installed on the front end of the outer wall of the clamping strip 410. An arc-shaped locking block 600 is fixedly installed on the front end of the outer wall of each connecting post 500. The sliding of the sliding rod 400 and the housing 100 allows the clamping strip 410 to slide back and forth, thereby driving the arc-shaped locking block 600 to slide back and forth. The arc-shaped locking block 600 clamps the pencil 1 to be painted onto the sliding strip 310. Electric telescopic push rods 420 are symmetrically fixedly installed on the rear side of the inner wall of the housing 100. The output ends of the two electric telescopic push rods 420 are fixedly connected to the rear end of the outer wall of the clamping strip 410. By activating the electric telescopic push rods 420, the clamping strip 410 is driven to slide back and forth. A rack 700 is fixedly connected to the lower side of the outer wall of the sliding strip 310 and located on the right side of the sliding frame 300. An installation plate 710 is fixedly installed on the right end of the outer wall of the housing 100. A motor 720 is fixedly installed on the upper end of the outer wall of the installation plate 710. A gear 730 is fixedly installed on the output end of the motor 720. The gear 730 and the rack 700 are meshed. By activating the motor 720, the gear 730 is driven to rotate, thereby driving the rack 700 to slide left and right, allowing the sliding strip 310 to slide left and right inside the sliding frame 300. The left and right sliding of the sliding strip 310 causes the pencil 1 to rotate, so that paint can be evenly sprayed on all directions of the side wall of the pencil 1. The slider 310 and the clamping bar 410 are located on the same horizontal plane, which can ensure the stability of the pencil 1 when it is clamped.

[0024] In this embodiment: First, pencil 1 is placed between the arc-shaped clamping block 600 and the sliding bar 310. The sliding bar 410 can slide back and forth by sliding the sliding rod 400 and the housing 100. Paint is pumped into the nozzle 200 through the connecting pipe 210. The side wall of pencil 1 is painted by the nozzle 200. Then, the electric telescopic push rod 420 is activated to drive the clamping bar 410 to slide forward, thereby driving the arc-shaped clamping block 600 to slide forward. The arc-shaped clamping block 600 clamps the pencil 1 to be painted on the sliding bar 310. Then, the motor 720 is activated to drive the gear 730 to rotate, thereby driving the rack 700 to slide left and right, allowing the sliding bar 310 to slide left and right inside the sliding frame 300. The left and right sliding of the sliding bar 310 causes the pencil 1 to rotate, so that paint can be sprayed on all directions of the side wall of the pencil 1.

[0025] Please refer to this carefully. Figure 3 and Figure 4 The arc-shaped clamping block 600 has a placement groove 610 inside, and a rotating rod 620 is rotatably connected inside the placement groove 610. A rotating wheel 630 is fixedly connected to the outer wall of the rotating rod 620. The rotation of the rotating wheel 630 further reduces the friction between the pencil 1 and the inner wall of the arc-shaped clamping block 600, making the rotation speed of the pencil 1 more stable. There are three rotating wheels 630, which are evenly arranged along the inner wall of the arc-shaped clamping block 600, so that the force on the clamped part of the pencil 1 is more even.

[0026] In this embodiment, the rotation of the rotating wheel 630 further reduces the friction between the pencil 1 and the inner wall of the arc-shaped block 600, making the rotation speed of the pencil 1 more stable, thereby making the paint thickness on the side wall of the pencil 1 more uniform.

[0027] Please refer to this carefully. Figure 1 and Figure 2 Input pipes 220 are fixedly installed on both the left and right sides of the outer wall of the connecting pipe 210.

[0028] In this embodiment: the input pipe 220 is connected to an external paint input device, and paint is pumped into the connecting pipe 210 through the input pipe 220.
