[0028] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments described are not intended to limit the present invention.

[0029] Example

[0030] Reference Figures 1 to 7As shown, a spraying device for producing a trimmer housing according to the present invention includes a spraying box 1, a cover plate 11 rotatably connected to the top of the spraying box 1; a sealing strip 12 fixedly connected to the top of the cover plate 11; an observation window 13 opened on the side wall of the spraying box 1; a drain outlet 14 fixedly connected to the side wall of the spraying box 1; a pair of storage boxes 15 fixedly connected to the side wall of the spraying box 1; a pair of spray nozzles 16 provided on the inner side wall of the spraying box 1; the spray nozzles 16 are connected to the storage boxes 15 through pipes; a first fixing rod 17 rotatably connected to the bottom of the spraying box 1; a pair of electric push rods 18 fixedly connected to the side wall of the first fixing rod 17; and so on.

As the support ring 19 moves upwards towards the placement platform 111, the support rod 110 on the side wall of the support ring 19 pushes the support seat 113 in the middle of the slide groove 112 to move. This allows multiple sets of support seats 113 to move simultaneously outwards from the placement platform 111 when a pair of electric push rods 18 push the support ring 19. The top rod 114 on the top of the support seat 113 can contact the inner side of the outer shell. By moving in conjunction with the support seat 113, an inner support structure can be formed on the outer side, thus fixing the outer shell to the top of the placement platform 111. Then, a pulling force is applied to the cover plate 11 to close the top of the spray box 1. The sealing strip 12 will fill the gap between the cover plate 11 and the spray box. 1. The top closed gap is then activated, and a pair of storage boxes 15 are started. The pump inside the storage box 15 can draw out the paint inside and then spray it from the nozzle 16. At this time, the drive motor at the bottom of the first fixing rod 17 can be started to drive the first fixing rod 17 to rotate, so that the outer shell on the top of the placement platform 111 rotates. In conjunction with the spraying of the pair of nozzles 16, the outer shell can be sprayed evenly. The spraying situation of the outer shell inside the spray box 1 can be observed through the observation window 13. After cleaning the inside of the spray box 1, a pulling force can be applied to the drain outlet 14 to remove the drain outlet 14 from the side wall of the spray box 1, and the cleaning impurities can be discharged from the drain outlet 14.The electric push rod 18 pushes the support ring 19, and the linkage support rod 110 drives multiple sets of support seats 113 to move synchronously, so that the top rod 114 forms a uniform support force on the inner side of the shell, which can quickly complete the fixing of the shell, shorten the preparation time, and reduce the possibility of the clamps blocking the outer spraying surface when fixing the shell from the outside, which would cause defects after spraying. The multiple sets of support seats 113 slide in the middle of the slide groove 112, which can also adapt to different types of shells, increasing the overall adaptability of the spray box 1 to spraying different shells. The drive motor at the bottom of the first fixing rod 17 is started, and the first fixing rod 17 drives the shell on the top of the placement platform 111 to rotate at a uniform speed. With the symmetrical spraying of a pair of spray heads 16 on the inner side wall of the spray box 1, the shell surface can receive paint evenly at every angle, reducing the uneven thickness caused by fixed spraying and ensuring a consistent coating thickness.

During operation, when multiple sets of top rods 114 move towards the inner wall of the housing, the multiple sets of top blocks 21 on the side wall of the top rod 114 can contact the inner wall of the housing. Subsequently, the support seat 113 continues to move, and the spring rods 2 can elastically retract, so that when the support seat 113 clamps the inner wall of the housing... Buffering clamping force; by the elastic contraction of the spring rod 2, when the top block 21 contacts the inner wall of the outer shell, the spring rod 2 can buffer the clamping force through elastic contraction, which can reduce the deformation of the outer shell caused by the continuous movement of the support seat 113 when the top rod 114 supports the inner wall of the outer shell. The cooperation of multiple sets of spring rods 2 and top blocks 21 can adapt to the irregular shape of the inner wall of the outer shell, ensuring that multiple sets of top blocks 21 are in close contact with the inner wall of the outer shell, reducing the irregularity of the inner wall of the outer shell, which would lead to insufficient contact surface when supporting the inner wall, and forming multi-point uniform clamping.

When the support base 113 slides in the middle of the slide groove 112, the cleaning plate 4 can clean the paint in the middle of the slide groove 112, and the scraper 41 can scrape away the more stubborn paint. By sliding synchronously with the support base 113 in the slide groove 112, the cleaning plate 4 can scrape away the residual paint in the middle of the slide groove 112. In conjunction with the scraper 41, it can further scrape away the stubborn paint, reducing the obstruction formed in the middle of the slide groove 112 after the paint has cured.

During operation, the nozzle 16 can also apply a pushing force to the slider 61 before spraying, allowing the slider 61 to slide on top of the slide rails 6, thereby adjusting the spraying distance between the nozzle 16 and the housing. By pushing the slider 61 to slide on top of the slide rails 6, the distance between the nozzle 16 and the housing can be flexibly adjusted, allowing paint droplets to be sprayed onto the housing surface at a suitable distance, reducing paint accumulation caused by the nozzle 16 being too close to the housing or the coating being too thin caused by the distance being too far.

[0036] Reference Figure 5As shown, a spraying device for producing a trimmer casing according to the present invention includes a storage box 15 with a rotating shaft 7 rotatably connected to its bottom end; a handle 71 rotatably connected to the top end of the rotating shaft 7; and multiple sets of agitating plates 72 fixedly attached to the side wall of the rotating shaft 7. During operation, after the paint inside the storage box 15 has been stored for a period of time, a rotational force can be applied to the handle 71 to drive the rotating shaft 7 to rotate, thereby causing the multiple sets of agitating plates 72 on the side wall of the rotating shaft 7 to agitate the paint inside the storage box 15. By rotating the agitating plates 72 to agitate the inside of the storage box 15, the sedimentation or stratification of the paint inside the storage box 15 caused by the paint remaining still for a long time is reduced.

[0037] Reference Figure 6 As shown, a spraying device for producing a trimmer casing according to the present invention includes a guide plate 8 fixedly connected to the side wall of the agitator 72; the guide plate 8 is inclinedly arranged on the side wall of the agitator 72; a fixing strip 81 is fixedly connected to the side wall of the guide plate 8; during operation, when the agitator 72 agitates the paint inside the storage box 15, the paint can contact the guide plate 8, the inclined arrangement of the guide plate 8 can guide the paint upward, and the fixing strip 81 can block the paint flowing out from the side of the guide plate 8; through the cooperation of the guide plate 8 and the fixing strip 81, the paint settled at the bottom of the storage box 15 can be guided upward when the agitator 72 agitates, realizing the circulation and mixing of the upper and lower layers of paint inside the storage box 15.

[0038] Reference Figure 1 As shown, a spraying device for producing trimmer housings according to the present invention includes a fixed base 9 fixedly connected to the inner wall of the spraying box 1; multiple sets of heating rods 91 are fixedly connected to the inner wall of the fixed base 9; during operation, after the housing inside the spraying box 1 is sprayed, the multiple sets of heating rods 91 on the side wall of the fixed base 9 can be activated, the heating rods 91 can emit high temperatures, and in conjunction with the first fixed rod 17, drive the housing on the top of the placement platform 111 to rotate, which can evenly dry the sprayed housing; through the high temperature emitted by the heating rods 91, in conjunction with the first fixed rod 17 driving the housing to rotate at a uniform speed, the sprayed housing can be evenly dried, shortening the drying time of the housing after coating and increasing the spraying efficiency.

[0039] Reference Figure 1 As shown, a spraying device for producing a trimmer housing according to the present invention includes a pair of baffles 10 fixed to the side wall of the fixed base 9; the baffles 10 are inclined; during operation, the pair of baffles 10 on the side of the fixed base 9 can reflect the heat emitted by the heating rod 91, thereby concentrating the heat; by the baffles 10 being inclined on both sides of the fixed base 9, the dispersed heat emitted by the heating rod 91 is concentrated in the central area of ​​the fixed base 9, which can further concentrate the heat and increase the contact efficiency between the heat and the coating on the surface of the housing.

[0040] The working principle of the spraying device for producing trimmer housings according to the present invention is as follows: The housing to be sprayed is placed on top of the placement platform 111. Then, a pair of electric push rods 18 on the side wall of the first fixing rod 17 are activated. The electric push rods 18 push the support ring 19 to move upwards on the placement platform 111. When the support ring 19 moves, the support rod 110 on the side wall of the support ring 19 pushes the support seat 113 in the middle of the slide groove 112 to move. This allows multiple sets of support seats 113 to move simultaneously outwards from the placement platform 111 when the pair of electric push rods 18 push the support ring 19. The top rod 114 on the top of the support seat 113 can contact the inner side of the housing. The movement of the support seat 113 in conjunction with the support seat 113 can form an inner support structure on the outer side, thus fixing the housing on top of the placement platform 111. Then, the cover plate 1... 1. Applying a pulling force closes the top of the spray box 1. The sealing strip 12 fills the gap between the cover plate 11 and the top of the spray box 1. Then, a pair of storage boxes 15 are activated. The pump inside the storage box 15 can draw out the paint and spray it from the nozzle 16. At this time, the drive motor at the bottom of the first fixing rod 17 can be activated to rotate the first fixing rod 17, causing the outer shell on the top of the placement platform 111 to rotate. In conjunction with the spraying of the pair of nozzles 16, the outer shell can be sprayed evenly. The spraying situation of the outer shell inside the spray box 1 can be observed through the observation window 13. After cleaning the inside of the spray box 1, a pulling force can be applied to the drain outlet 14 to remove the drain outlet 14 from the side wall of the spray box 1. The cleaning impurities can then be discharged from the drain outlet 14. When multiple sets of push rods 114 move outward... When the inner wall of the shell moves, the multiple sets of top blocks 21 on the side wall of the top rod 114 can contact the inner wall of the shell. Then the support seat 113 continues to move, and the spring rod 2 can retract elastically, so that the support seat 113 buffers the clamping force when clamping the inner wall of the shell. When the nozzle 16 sprays the shell on the top of the placement table 111, the shielding cloth 31 can prevent the sprayed material from contacting the electric push rod 18 and the support ring 19, and shield the sprayed material outside the shielding cloth 31. Some of the material sprayed by the nozzle 16 will stick to the middle of the slide 112. When the support seat 113 slides in the middle of the slide 112, the cleaning plate 4 can clean the paint in the middle of the slide 112, and the scraper 41 can scrape off the more stubborn paint. Before the shell is placed on the top of the placement table 111, the support plate 51 can be... By applying tension, the overall height of the second fixing rod 5 can be adjusted. Then, rotating the bolts on the side wall of the second fixing rod 5 can fix the support plate 51. When the outer casing is placed on top of the placement platform 111, the support plate 51 can support the middle area of ​​the outer casing. Before spraying, the nozzle 16 can also apply a pushing force to the slider 61, allowing the slider 61 to slide on top of the slide rail 6, adjusting the spraying distance between the nozzle 16 and the outer casing. After the paint inside the storage box 15 has been stored for a period of time, a rotational force can be applied to the handle 71, causing the rotating shaft 7 to rotate. This causes the multiple sets of agitating plates 72 on the side wall of the rotating shaft 7 to agitate the paint inside the storage box 15. When the agitating plates 72 agitate the paint inside the storage box 15, the paint can contact the guide plate 8. The inclined setting of the guide plate 8 allows the paint to be guided upwards.The fixing strip 81 blocks the paint from flowing out from the side of the guide plate 8. After the outer shell inside the spray box 1 is sprayed, multiple sets of heating rods 91 on the side wall of the fixing base 9 can be activated. The heating rods 91 can emit high temperatures, which, together with the first fixing rod 17, drive the outer shell on the top of the placement platform 111 to rotate, thus evenly drying the sprayed outer shell. A pair of baffles 10 on the side of the fixing base 9 can reflect the heat emitted by the heating rods 91, thus concentrating the heat.
