DETAILED DESCRIPTION

[0026] The following is a combination of specific implementation cases and attached Figures 1 to 6 The present invention is further described below, but the present invention is not limited to these embodiments.

[0027] In view of the problem that after static spraying, the undried paint will flow to the grooves on the surface of the car guard plate and gather into droplets. After drying, the droplets form bulges in the grooves, affecting the final flatness of the spraying, and thus affecting the qualified rate of the finished product of the car guard plate spraying process, please refer to Figures 1 to 6 As shown, a vehicle guard plate spraying device is proposed, comprising a box body 1, a driving shaft 2 is rotatably mounted in the middle of the inner cavity of the box body 1 through a bearing, a rotating seat 3 is mounted on the top of the driving shaft 2, and when the driving shaft 2 rotates, the rotating seat 3 can be driven to rotate synchronously, the upper surface of the rotating seat 3 is inclined, and a convex edge 4 is mounted on the upper surface of the rotating seat 3, see Figure 4 and Figure 5As shown, a slide groove 5 is provided at the top of the convex edge 4 along the circumferential direction, that is, the rotating seat 3, the convex edge 4 and the slide groove 5 are all inclinedly arranged, and two first balls 6 are rotatably embedded in the inner cavity of the slide groove 5, and the two first balls 6 are symmetrically arranged with the vertical central axis of the rotating seat 3 as the axis, and a first driving rod 7 is installed on the top of the first ball 6. The two left-right symmetrically arranged first balls 6 can ensure that the two first driving rods 7 are also left-right symmetrical. The first driving rod 7 slides upward and penetrates the outer wall of the box body 1, that is, the first driving rod 7 can only move in the vertical direction under the limiting action of the box body 1. Due to the rotating seat 3, The convex edge 4 and the slide groove 5 are both inclined, so when the rotating seat 3 rotates, the first ball 6 can be urged to roll along the inner cavity of the slide groove 5, while realizing the lifting and lowering movement of the first driving rod 7. Since there is a height difference between the two first driving rods 7 set in the initial position, the left and right first driving rods 7 are driven by the rotating seat 3 to lift and lower the two first driving rods 7 alternately. The top of the first driving rod 7 is equipped with a second ball 8. When the first driving rod 7 is lifted and lowered, the second ball 8 can be urged to lift and lower synchronously. A placement box 14 is arranged on the top of the second ball 8, see Figure 6 As shown, two slots 15 are provided on the lower surface of the placement box 14, and the second sphere 8 is rolled and embedded in the inner cavity of the slot 15 at the corresponding position. Since the second sphere 8 at the top of the first driving rod 7 is rolled and embedded in the inner cavity of the slot 15 and will not separate from the inner cavity of the slot 15, the lifting and lowering movement of the first driving rod 7 causes the placement box 14 to perform a left-right swinging reciprocating motion, so that the automobile guard plate placed in the inner cavity of the placement box 14 is evenly sprayed during the movement.

[0028] The specific principle of realizing dynamic uniform spraying of the automobile guard plate in the inner cavity of the placement box 14 is as follows: the rotating seat 3 is driven to rotate by the driving shaft 2. Since the upper surface of the rotating seat 3, the convex edge 4 and the slide groove 5 are all inclined, the rotating seat 3 causes the convex edge 4 at the top of the rotating seat 3 to perform a height conversion movement during the rotation process. Since the left and right first driving rods 7 penetrate the outer wall of the box body 1, and the first sphere 6 at the bottom of the first driving rod 7 is embedded in the inner cavity of the slide groove 5, the left and right first driving rods 7 are driven by the height conversion movement. The second sphere 8 at the top of the first driving rod 7 rolls and is embedded in the inner cavity of the card slot 15 and will not separate from the inner cavity of the card slot 15. Therefore, the lifting and lowering movement of the first driving rod 7 causes the placement box 14 to perform a left-right swinging reciprocating motion, so as to cause the automobile guard plate placed in the inner cavity of the placement box 14 to be evenly sprayed during the movement, thereby avoiding the accumulation of droplets in the inner cavity of the groove of the statically placed automobile guard plate.

[0029] In addition, see Figure 5As shown, the shape of the slide groove 5 is adapted to the shape of the first sphere 6, and the diameter of the top of the inner cavity of the slide groove 5 is smaller than the diameter of the first sphere 6, thereby ensuring that the first sphere 6 can stably move along the inner cavity of the slide groove 5 without escaping from the inner cavity of the slide groove 5 upward.

[0030] Specific reference Figure 1 and Figure 2 As shown, the placement box 14 is configured as a basin-shaped body that is wide at the top and narrow at the bottom, thereby ensuring that the top of the placement box 14 is open to the outside, which is more conducive to placing or removing the automobile guard plate in the inner cavity of the placement box 14 and facilitating loading and unloading operations.

[0031] See also Figure 3 As shown, the bottom end of the driving shaft 2 penetrates downward through the outer wall of the box body 1, and the driving shaft 2 is rotated by the driving unit. The driving unit includes a first pulley 9 installed at the bottom end of the outer wall of the driving shaft 2, and also includes a second driving rod 10 rotatably connected to the bottom end of the outer wall of the box body 1 through a bearing. A second pulley 11 is installed on the outer wall of the second driving rod 10, and a belt 12 is sleeved on the outer walls of the first pulley 9 and the second pulley 11. A motor 13 is installed at the bottom end of the outer wall of the box body 1 through a motor frame. The motor frame is vertically and fixedly installed at the bottom end of the box body 1, and the motor 13 is installed on the front side of the motor frame. The motor frame is fixedly connected to the bottom end of the outer wall of the box body 1, and the output end of the motor 13 is connected to the second driving rod 10. The turned-on motor 13 causes the second driving rod 10 and the second pulley 11 to rotate, so that the belt 12 drives the first pulley 9 to rotate. When the first pulley 9 rotates, the driving shaft 2 is caused to rotate synchronously to realize the rotation of the rotating seat 3.

[0032] See also Figure 1 and Figure 2 As shown, a mounting seat 16 is installed at the bottom end of the side wall of the box body 1, and two support arms 17 are vertically installed on the upper surface of the mounting seat 16. A top plate 18 is installed on the top of the support arm 17. The support arm 17 and the top plate 18 can provide support for the installation of other components, and a lifting unit is provided on the outer wall of the top plate 18; the lifting unit includes a lifting rod 19 that slides along the vertical direction and penetrates the outer wall of the top plate 18, and a movable plate 20 is installed on the top of the lifting rod 19. The lifting unit also includes a cylinder 21 installed on the upper surface of the top plate 18, and the output end of the cylinder 21 is connected to the lower surface of the movable plate 20. The cylinder 21 is a self-locking cylinder commonly used in the market, and its output end can stay at any position and be locked. The output end of the cylinder 21 moves upward, prompting the movable plate 20 and the lifting rod 19 to move upward, leaving enough space for taking out the automobile guard plate after spraying in the inner cavity of the placement box 14.

[0033] See also Figure 1 and Figure 2As shown, a material pipe 22 is installed at the bottom of the lifting rod 19, and a plurality of nozzles 23 are equidistantly arranged on the outer wall of the material pipe 22 from left to right. The top of the nozzle 23 is connected with a connecting pipe 24, and a pump body 25 and a paint tank 26 are installed at the top of the mounting seat 16. The pump body 25 is connected with the paint tank 26 and the connecting pipe 24 respectively. The material pipe 22, the nozzle 23, the connecting pipe 23, the pump body 25 and the paint tank 26 are all existing components, which can meet the needs of paint spraying, and the specific connection method and other settings are not excessively described here;

[0034] The automobile guard plate to be sprayed is placed in the inner cavity of the placement box 14, and the paint in the inner cavity of the paint can 26 is pumped to the inner cavity of the connecting pipe 24 through the opened pump body 25, and sprayed downward through the material pipe 22 and the nozzle 23; in addition, after the automobile guard plate is sprayed, the output end of the opened cylinder 21 moves upward, prompting the movable plate 20, the lifting rod 19, the material pipe 22 and the nozzle 23 to move upward synchronously, leaving enough space for taking out the sprayed automobile guard plate from the inner cavity of the placement box 14, and by adjusting the position of the nozzle 23, it can adapt to the spraying requirements of automobile guard plates of different thicknesses.

[0035] The working principle of a vehicle guard plate spraying device in this embodiment is as follows:

[0036] The automobile fender to be sprayed is placed in the inner cavity of the placement box 14, and the paint in the inner cavity of the paint tank 26 is pumped to the inner cavity of the connecting pipe 24 through the opened pump body 25, and sprayed downward through the material pipe 22 and the spray head 23;

[0037] The turned-on motor 13 causes the second driving rod 10 and the second pulley 11 to rotate, so that the belt 12 drives the first pulley 9 to rotate. When the first pulley 9 rotates, the driving shaft 2 is caused to rotate synchronously to realize the circumferential rotation of the rotating seat 3. Since the upper surface of the rotating seat 3, the convex edge 4 and the slide groove 5 are all inclined, the two first balls 6 embedded in the inner cavity of the slide groove 5 can be lifted and moved alternately in succession during the rotation of the rotating seat 3. Since the left and right two first driving rods 7 penetrate the outer wall of the box body 1, the left and right two first driving rods 7 can be lifted and moved alternately in succession under the action of the rotating slide groove 5. Since the second ball 8 at the top of the first driving rod 7 rolls and is embedded in the inner cavity of the card slot 15 and will not separate from the inner cavity of the card slot 15, the lifting and lowering movement of the first driving rod 7 causes the placement box 14 to perform a reciprocating motion of swinging left and right, so as to cause the automobile guard plate placed in the inner cavity of the placement box 14 to be evenly sprayed during the movement, so as to avoid the accumulation of droplets in the inner cavity of the groove of the statically placed automobile guard plate.

[0038] After the car guard plate is sprayed, the output end of the opened cylinder 21 moves upward, prompting the movable plate 20, the lifting rod 19, the material pipe 22 and the nozzle 23 to move upward synchronously, leaving enough space for taking out the sprayed car guard plate from the inner cavity of the placement box 14, and by adjusting the position of the nozzle 23, it can adapt to the spraying requirements of car guard plates of different thicknesses;

[0039] The utility model can drive the automobile guard plate placed in the inner cavity of the placement box 14 to perform left and right swinging reciprocating motion, so that the paint can flow in the inner cavity of the automobile guard plate groove. Compared with the static spraying method, it can avoid the paint from gathering into droplets in the automobile guard plate groove, thereby avoiding the formation of subsequent protrusions. The paint can be sprayed evenly in the inner cavity of the automobile guard plate to ensure the qualified rate of the finished products of the automobile guard plate spray painting process.
