Description

Technical Field

[0001] This invention relates to the field of spray painting equipment technology, and in particular to a filter housing painting device. Background Technology

[0002] During manufacturing, filter housings require surface polishing and painting. Current painting methods typically involve placing the housing in a sealed enclosure and spraying it 360 degrees without blind spots using a spray painting machine. Hot air is then used to dry the painted housing to prevent damage to the paint layer during removal. However, this hot air drying process also affects the spray nozzles and other components in the spray painting machine. This causes any residual paint in the pores to dry and clump quickly, potentially clogging the nozzle orifices and affecting subsequent normal use. Summary of the Invention

[0003] The purpose of this invention is to provide a filter housing painting device.

[0004] The technical problem of this invention is mainly solved by the following technical solution:

[0005] A filter housing painting device includes a painting box mounted on a base, a circular seat driven by a motor at the bottom of the painting box, a locking mechanism at the top of the circular seat, a painting mechanism inside the painting box outside the circular seat, and a drying mechanism inside the painting box above the circular seat and the painting mechanism.

[0006] The drying mechanism includes a top plate located at the top of the paint tank and driven vertically by a hydraulic rod. A cylinder penetrating the top wall of the paint tank is provided at the bottom of the top plate. An exhaust pipe is provided on the top plate inside the cylinder. A ring is provided at the bottom of the cylinder. A heating pipe is provided on the inner wall of the cylinder above the ring. A sealing seat is provided inside the ring. A C-shaped rod penetrating the top plate and connected to the sealing seat is provided at the top of the paint tank.

[0007] Preferably, the painting mechanism includes a paint spraying pipe located outside the circular base. The paint spraying pipe is horizontally driven by an electric push rod outside the upper paint tank. The paint spraying pipe is located between the circular base and the bottom of the cylinder. Atomizing nozzles are evenly arranged on the side wall of the paint spraying pipe. The paint spraying pipe is connected to the paint storage tank through a hose equipped with a pump.

[0008] Preferably, the sealing seat seals the internal opening of the ring, and the sealing seat has an inverted conical structure.

[0009] Preferably, the locking mechanism includes sliding channels on both sides of the circular seat, wherein the end of the sliding channel away from the edge of the circular seat is provided with a sliding opening communicating with the outer side of the top of the circular seat, a slider is provided in the sliding channel, wherein the end of the slider away from the sliding opening is connected to the corresponding side wall of the sliding channel by a spring, and the top of the circular seat is also provided with an L-shaped block passing through the sliding opening and connected to the corresponding slider, and the end of the L-shaped block is provided with a right-angled trapezoidal locking block located above the circular seat.

[0010] Preferably, a collection groove is arranged around the top of the base inside the paint box, and the edge of the circular base extends to the top of the opening of the collection groove. A scraper adapted to the collection groove is provided inside the collection groove. The scraper is connected to the circular base through a connecting rod. An outlet pipe communicating with the bottom of the collection groove is also provided on the base.

[0011] The beneficial effects of this invention are as follows: In this invention, the spraying mechanism performs 360-degree painting on the outer wall of the rotating housing. When the outer wall of the housing needs to be dried, the spraying mechanism moves down, so that the cylinder and the ring are wrapped around the housing on the top of the circular seat. At this time, the heating tube works to generate hot air to dry the paint layer on the outer wall of the housing. At the same time, due to the influence of the cylinder, the hot air flow after heating inside will not come into contact with components such as the atomizing nozzle, preventing the residual paint in the atomizing nozzle from drying and clumping and clogging it, thereby effectively ensuring the normal use of the atomizing nozzle in the future.

[0016] The technical solution of the present invention will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0017] A filter housing painting device includes a painting box 2 set on a base 1. A circular seat 4 driven by a motor 3 is set at the bottom of the painting box 2. A locking mechanism 5 is set at the top of the circular seat 4. A painting mechanism 6 is set in the painting box 2 outside the circular seat 4. A drying mechanism 7 is set in the painting box 2 above the circular seat 4 and the painting mechanism 6.

[0018] The drying mechanism 7 includes a top plate 72 located at the top of the paint tank 2 and vertically driven by a hydraulic rod 71. A cylinder 73 penetrating the top wall of the paint tank 2 is provided at the bottom of the top plate 72. An exhaust pipe 74 is provided on the top plate 72 inside the cylinder 73. A ring 75 is provided at the bottom of the cylinder 73. A heating tube 76 is provided on the inner wall of the cylinder 73 above the ring 75. A sealing seat 77 is provided inside the ring 75. A chamfered rod 78 penetrating the top plate 72 and connected to the sealing seat 77 is provided at the top of the paint tank 2. The sealing seat 77 seals the opening inside the ring 75. The sealing seat 77 has an inverted conical structure.

[0019] The painting mechanism 6 includes a paint spraying pipe 61 located outside the circular base 4. The paint spraying pipe 61 is horizontally driven by an electric push rod 62 outside the upper paint tank 2. The paint spraying pipe 61 is located between the circular base 4 and the bottom of the cylinder 73. Atomizing nozzles 63 are evenly arranged on the side wall of the paint spraying pipe 61. The paint spraying pipe 61 is connected to the paint storage tank through a hose equipped with a pump.

[0020] The locking mechanism 5 includes sliding channels 51 disposed on both sides of the circular base 4. The end of the sliding channel 51, away from the edge of the circular base 4, has a sliding opening 53 communicating with the outer top of the circular base 4. A slider 52 is disposed within the sliding channel 51. The end of the slider 52, away from the sliding opening 53, is connected to the corresponding sidewall of the sliding channel 51 by a spring 54. The top of the circular base 4 also has an L-shaped block 55 passing through the sliding opening 53 and connected to the corresponding slider 52. The end of the L-shaped block 55 has a right-angled trapezoidal locking block 56 located above the circular base 4. Figure 2 , 3 As shown, the bottom edge of the locking block 56 is located at the top, and its inclined end is on the same side as the edge of the circular seat 4.

[0021] like Figure 2 , 3 As shown, a collection trough 8 is arranged around the top of the base 1 inside the paint box 2. The edge of the circular seat 4 extends to the top of the opening of the collection trough 8. A scraper 9 adapted to it is provided in the collection trough 8. The scraper 9 is connected to the circular seat 4 through a connecting rod 10. The base 1 is also provided with a liquid outlet pipe 11 that communicates with the bottom of the collection trough 8.

[0022] The method of using this invention is as follows: By opening the switch door on the paint box 2, the filter housing is placed on the circular seat 4 inside it. The housing is placed on top of two sets of locking blocks 56. The filter housing is generally cylindrical. After placing the bottom end of its side wall on the inclined surface of the two sets of locking blocks 56, the bottom end of the side wall of the housing will slide downward on the inclined surface of the locking blocks 56 under the influence of the weight of the housing or the force applied by the user. The downward squeezing force will force the locking blocks 56 to move towards the middle of the circular seat 4. At the same time, the locking blocks 56 will drive the L-shaped blocks 55 to slide in the corresponding sliding opening 53. The L-shaped blocks 55 will also drive the slider 52 to slide in the sliding channel 51 and pull the spring 54 to stretch it. When the bottom end of the housing contacts the circular seat 4, it is supported and fixed by it. At this time, the contraction force of the spring 54 acts on both sides of the bottom opening of the housing through the slider 52, the L-shaped blocks 55 and the locking blocks 56, thereby locking the housing to prevent it from horizontal displacement.

[0023] Next, the electric push rod 62 can drive the paint spray pipe 61 to move above the circular seat 4 and close to the outer wall of the housing above the circular seat 4. At this time, the motor 3 drives the circular seat 4 to rotate the housing. At the same time, the pump introduces the paint liquid in the paint storage tank into the paint spray pipe 61 through the pipeline and sprays it out by the atomizing nozzle 63. This allows the sprayed paint mist to cover the entire outer wall of the housing during the rotation process, thus performing a uniform painting work on its outer wall. At this time, since the bottom opening of the cylinder 73 is sealed by the ring 75 and the sealing seat 77, no paint mist or pungent odor will flow out through the drying mechanism 7.

[0024] When the paint is applied and the outer wall of the housing needs to be dried, the paint spray pipe 61 moves to the outside of the circular seat 4. At the same time, the hydraulic rod 71 drives the top plate 72 to move downward. The top plate 72 drives the cylinder 73 to slide downward in the circular hole on the top wall of the paint tank 2, and the through hole on the top plate 72 slides on the U-shaped rod 78. At this time, the cylinder 73 also drives the ring 75 and the heating pipe 76 to move downward. When the cylinder 73 contacts the top of the circular seat 4, the hydraulic cylinder 71 stops working. At this time, the cylinder 73 and the ring 75 are sleeved on the housing at the top of the circular seat 4, and a gap for gas flow is formed between the sealing seat 77 and the inner wall of the cylinder 73, as detailed below. Figure 3 As shown, the heating tube 76 then generates hot air to dry the paint layer on the outer wall of the housing. At the same time, due to the obstruction of the cylinder 73, the heated airflow inside will not come into contact with components such as the atomizing nozzle 63, preventing the residual paint in the atomizing nozzle 63 from drying and clumping and clogging it. This effectively ensures the normal use of the atomizing nozzle 63. Furthermore, the pungent odor generated during the drying of the paint layer of the housing can be extracted to a gas purification device (which is a commonly known device and will not be described in detail) through a pipe connected to the exhaust pipe 74 and equipped with an exhaust fan, to prevent a large amount of pungent odor from flowing out when the paint box 2 is opened later.

[0025] After drying is complete and the drying mechanism 7 is reset, the housing can be removed from the locking mechanism 5 and the circular seat 4, and then taken out through the inlet / outlet opening on the side wall of the paint box 2. Figure 2 , 3 As shown, the paint dripping during the painting process can flow into the collection tank 8. When the circular seat 4 rotates, it drives the scraper 9 to rotate through the connecting rod 10, which can scrape the paint in the collection tank 8 to the outlet pipe 11. Then, the paint can be introduced into the corresponding recycling container by opening the outlet pipe 11. Since the heat generated by the drying mechanism 7 when drying the shell is blocked by the cylinder 73, it will not come into contact with the paint in the collection tank 8, which can effectively prevent it from affecting the recycling of the paint in the collection tank 8.

[0026] The present invention has been described in detail above, but the content described is only a preferred embodiment of the present invention and should not be considered as limiting the scope of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the patent coverage of the present invention.
