Description

Technical Field

[0001] This utility model relates to the field of spraying equipment technology, specifically to a water pump housing primer spraying equipment. Background Technology

[0002] Currently, after the water pump housing is cast or stamped, in order to prevent the housing from rusting, an anti-rust primer is usually applied to the water pump housing. After the primer is applied, the water pump housing needs to be transferred to a drying equipment for drying treatment, so that the primer can adhere more firmly to the outside of the water pump housing.

[0003] Patent CN214021524U discloses a water pump housing primer spraying device, including a working box, an air extractor, an indexing plate, and a spraying mechanism. Two rotating carrier plates are fixedly mounted on the indexing plate, each with several contour-following fixed mold bases. The spraying mechanism includes an X-axis servo linear module, a Z-axis servo linear module, a Y-axis servo linear module, a paint tank, and a spray gun. The X-axis servo linear module is fixed to the top surface of the working box, the Y-axis servo linear module is connected to it, and the Z-axis servo linear module is connected to it. A sliding block is connected to the Z-axis servo linear module, and the spray gun is fixed to the bottom of the sliding block. The paint tank outlet is connected to the spray gun via a conveying pipe passing through the working box. The air extractor is fixed to the top of the working box. This device can automatically spray primer onto multiple water pump housings, offering relatively high efficiency and strong practicality.

[0004] However, the water pump housing primer spraying equipment mentioned above still has the following problems: the surface of the water pump housing often has recessed structures such as heat dissipation grooves and bolt mounting grooves. After spraying, the primer is prone to flow to the recessed areas due to gravity, forming local accumulation, resulting in uneven paint film thickness and affecting the adhesion of subsequent topcoat. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the water pump housing primer spraying equipment provided by this utility model can improve the primer spraying effect of water pump housing.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a water pump housing primer spraying device, including a support base, a plurality of support legs fixedly connected to the bottom of the support base, a primer bucket fixedly connected to the middle position of the support base, a rotating component connected to the bottom of the primer bucket, the rotating component being located above the support base, a spraying support frame and a drying support frame connected to the outside of the primer bucket, a spraying component connected inside the spraying support frame, the spraying component communicating with the primer bucket, a drying component connected inside the drying support frame, and a bucket lid threadedly connected to the top of the primer bucket.

[0009] Furthermore, the painting assembly includes several paint pumps and several spray nozzles. The paint pumps are all fixedly installed on the top of the painting support frame. The output ends of the paint pumps are all fixedly connected to and communicate with L-shaped paint guide tubes.

The output ends of the spray nozzles are all vertically downward, and the spray nozzles are evenly arranged on the side of the painting support frame near the support base. The input ends of the paint pumps are all communicated with the primer tank.

[0010] Furthermore, several paint pumps are arranged in two staggered rows on the top of the paint support frame.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Please see Figures 1 to 7 A water pump housing primer spraying equipment includes a support base 1, with several support legs 11 fixedly connected to the bottom of the support base 1. A primer tank 2 is fixedly connected to the middle position of the support base 1. A rotating component 3 is connected to the bottom of the primer tank 2 and is located above the support base 1. A spraying support frame 4 and a drying support frame 5 are connected to the outside of the primer tank 2. A spraying component 6 is connected inside the spraying support frame 4 and communicates with the primer tank 2. A drying component 7 is connected inside the drying support frame 5. A tank lid 21 is threadedly connected to the top of the primer tank 2.

[0027] like Figures 1 to 7 As shown, the main improvement of this utility model lies in improving the primer spraying effect and spraying stability, such as... Figures 1 to 7 As shown, in use, the water pump housing primer spraying equipment of this utility model places the water pump housing on the rotating component 3. The rotating component 3 drives the water pump housing to pass through the spraying support frame 4 and the drying support frame 5 at a uniform speed. To further improve the primer spraying effect on the water pump housing, the drying support frame 5 and the drying component 7 can be installed at both the front and rear ends of the spraying support frame 4. The drying component 7 at the front end performs pre-spray drying treatment on the water pump housing to be sprayed, ensuring that the water pump housing about to enter the spraying support frame 4 remains dry. This allows the spraying component 6 to spray the primer onto the dry outside of the water pump housing, forming a stronger adhesion effect. After the water pump housing is sprayed with primer, the rotating component 3 continues to drive the water pump housing to rotate and move to the drying support frame 5 at the rear end. The internal drying component 7 then performs further drying on the water pump housing that has just been primed. The air-drying process reduces the fluidity of the primer adhering to the outer surface of the water pump housing, preventing the primer from flowing into the recesses on the outside of the water pump housing and forming local accumulations. This ensures that the primer adheres more stably and evenly to the outside of the water pump housing, thereby effectively improving the effect and stability of the primer spraying. The air-dried primer also prevents the water pump housing from sticking to the hands or shell removal equipment when it is removed from the rotating assembly 3. The primer bucket 2 in the middle of the support base 1 can store the primer and supply primer to the spraying assembly 6. The spraying support frame 4 and the air-drying support frame 5 are both inverted U-shaped structures, with one end abutting against the outside of the primer bucket 2 and the other end fixed to the edge of the support base 1. The spraying assembly 6 and the air-drying assembly 7 are both located on top of the inverted U-shaped structure, and the inverted U-shaped structure can block the spraying to a certain extent, preventing the primer from flying into the external environment and causing pollution during the spraying process.

[0028] like Figures 1 to 3As shown, the rotating assembly 3 includes a rotating bearing 31 and an annular rotating platform 32. The inner ring of the rotating bearing 31 is fitted onto the outer wall of the bottom of the primer bucket 2, and the inner ring of the rotating bearing 31 is fixedly connected to the outer wall of the bottom of the primer bucket 2. The annular rotating platform 32 is fitted onto the outer side of the rotating bearing 31, and the annular rotating platform 32 is fixedly connected to the outer ring of the rotating bearing 31. An annular slide bar 33 is fixedly connected to the bottom of the annular rotating platform 32. An annular groove 101 is provided on the upper surface of the support base 1. The annular slide bar 33 is slidably connected to the annular groove 101. A drive assembly 8 is connected to the outer side of the annular rotating platform 32. The rotary bearing 31 can provide rotational support for the annular rotary table 32, and at the same time, the primer bucket 2 limits the position of the annular rotary table 32. When the drive assembly 8 drives the annular rotary table 32 to rotate and transport the water pump housing on the support base 1, the middle position of the annular rotary table 32 is supported by the rotary bearing 31, and the outer side of the annular rotary table 32 is supported by the sliding of the bottom annular slide bar 33 in the annular slide groove 101 on the support base 1. This allows the annular rotary table 32 to more stably drive the water pump housing to alternate between the painting assembly 6 and the drying assembly 7, and smoothly complete the painting and drying operations of the water pump housing.

[0029] like Figure 1 and Figure 2 As shown, the drive assembly 8 includes a drive motor 81 and a drive gear 82. The outer side of the annular rotary table 32 has several toothed grooves 301. The drive motor 81 is fixedly mounted on the outer bottom of the support base 1 via a motor mount. The output axis of the drive motor 81 extends upwards to the outer side of the annular rotary table 32 and is fixedly connected to the drive gear 82. The drive gear 82 meshes with the toothed grooves 301. Starting the drive motor 81 drives the drive gear 82 to rotate. Subsequently, through the meshing of the drive gear 82 with the toothed grooves 301 on the outer side of the annular rotary table 32, the annular rotary table 32 can be driven to rotate and move on the support base 1. In use, the paint spraying water pump housing is placed on the annular rotary table 32. The rotation of the annular rotary table 32 drives the water pump housing to pass sequentially through the pre-painting drying support frame 5, the paint spraying support frame 4, and then back to the housing placement position from the post-painting drying support frame 5. At this point, the dried paint spraying housing can be removed.

[0030] like Figures 1 to 5As shown, the paint spraying assembly 6 includes several paint pumps 61 and several nozzles 62. The paint pumps 61 are all fixedly installed on the top of the paint spraying support frame 4. The output ends of the paint pumps 61 are all fixedly connected and communicated with L-shaped paint guide tubes 63. The other ends of the L-shaped paint guide tubes 63 all pass downward through the top of the paint spraying support frame 4 and are fixedly connected and communicated with the nozzles 62 respectively. The output ends of the nozzles 62 are all vertically downward, and the nozzles 62 are evenly arranged on the side of the paint spraying support frame 4 near the support base 1. The input ends of the paint pumps 61 are all communicated with the primer tank 2. The paint pump 61 can extract the primer from the primer bucket 2 and guide it from the L-shaped paint guide tube 63 to the nozzle 62. Finally, the primer is sprayed from the nozzle 62 onto the water pump housing below the paint support frame 4, completing the primer spraying operation of the entire water pump housing. Multiple nozzles 62 can improve the primer spraying effect of the water pump housing. At the same time, when the water pump housing rotates on the annular rotating table 32, the moving speed towards the outside of the annular rotating table 32 will be greater than the moving speed towards the inside. At this time, by adjusting different paint pumps 61, multiple evenly arranged nozzles 62 can form different spray volumes from the inside to the outside, thereby making the primer spraying of the water pump housing more uniform.

[0031] like Figures 1 to 4 As shown, several paint pumps 61 are arranged in two staggered rows on the top of the paint support frame 4. The input ends of several paint pumps 61 in the same row are fixedly connected to and connected to a distribution pipe 64. The two distribution pipes 64 are fixedly connected to and connected to a paint extraction pipe 65 through a T-joint. The other end of the paint extraction pipe 65 passes through the top of the primer tank 2 and into the interior of the primer tank 2. The end of the paint extraction pipe 65 inside the primer tank 2 extends to the bottom of the primer tank 2, leaving a certain gap with the bottom of the primer tank 2. The staggered arrangement of the paint pumps 61 can avoid mutual interference during installation. The primer in the primer tank 2 can be delivered to the two rows of multiple paint pumps 61 through the two distribution pipes 64.

[0032] like Figures 1 to 7 As shown, the air-drying assembly 7 includes an air duct 71 and several fans 72. The air duct 71 is fixedly installed on the top of the air-drying support frame 5, and the top end of the air duct 71 penetrates through the top of the air-drying support frame 5. A fixing rod 73 is fixedly connected to the inner wall of the air duct 71, and several fans 72 are equidistantly fixed at the bottom of the fixing rod 73. The multiple fans 72 are fixedly installed inside the air duct 71 by the fixing rod 73. When the fans 72 are activated, the airflow blows from the bottom of the air duct 71 onto the water pump housing on the annular rotary table 32, thereby performing the air-drying operation of the water pump housing or the primer on the outside of the water pump housing.

[0033] like Figures 1 to 6As shown, a protective net 51 is connected to the top of the air-drying support frame 5, and the protective net 51 covers the top opening of the air duct 71. By installing the protective net 51 on the top of the air duct 71, impurities carried by the airflow can be prevented from entering the air duct 71 and adhering to the outside of the water pump housing with the airflow, thereby improving the stability of the air-drying operation.

[0034] like Figures 1 to 6 As shown, a pressure frame 52 is connected to the top of the air-drying support frame 5. Several hinges 53 are fixedly connected to one side of the pressure frame 52, and the other ends of the hinges 53 are fixedly connected to the top of the air-drying support frame 5. The pressure frame 52 is matched with the top of the air duct 71. A fixing strip 54 is fixedly connected to the side of the pressure frame 52 away from the hinges 53. The fixing strip 54 is fixedly connected to the top of the air-drying support frame 5 by multiple bolts. The protective net 51 is located between the air duct 71 and the pressure frame 52. The hinges 53 allow the pressure frame 52 to be easily flipped open on the air-drying support frame 5, and the fixing strip 54 is tightened onto the air-drying support frame 5 using bolts. The pressure frame 52 presses the protective net 51 tightly onto the air duct 71, which allows for timely replacement of the protective net 51 when it is damaged, maintaining the impurity filtration effect of the air-drying assembly 7.

[0035] like Figures 1 to 7 As shown, a ceramic ring 74 is fixedly connected to the inner wall of the bottom of the air duct 71, and several equally spaced heating rods 75 are fixedly connected inside the ceramic ring 74. The heating rods 75 inside the ceramic ring 74 can be used to heat the airflow blown from the air duct 71 towards the water pump housing, thereby improving the drying effect on the water pump housing and the water pump housing after painting.
