Description

Technical Field

[0001] The utility model relates to a painting exhaust tool and belongs to the technical field of automobile painting equipment. Background Art

[0002] In the bus electrophoretic coating production line, due to the limitations of production line planning and electrophoretic equipment, the body of the entire vehicle moves vertically up and down. During the electrophoretic process, electrophoretic cavities are easily formed inside the vehicle body due to the inability to discharge local air. The electrophoretic fluid in this area cannot adhere normally, which seriously affects the anti-corrosion performance of the vehicle body. Utility Model Content

[0003] The technical problem to be solved by the present invention is to provide a painting exhaust tool to solve the technical problems existing in the above-mentioned prior art.

[0004] The technical solution adopted by the present invention is: a painting exhaust tooling, comprising a base fixed to the bottom of the electrophoresis pool, the upper end of the base being detachably connected to a riser, the lower part of the riser being connected to an exhaust hose via a first tee, the upper end of the exhaust hose extending above the liquid surface of the electrophoresis pool; the upper end of the riser being detachably connected to a second tee, the left and right ends of the second tee being respectively connected to one or more third tees in sequence via pipes, the end of the third tee at the end away from the second tee being connected to a right-angled two-way via a pipe, and the vertical ends of all the third tees and the right-angled two-way are connected to an air intake pipe arranged vertically upwards.

[0005] Preferably, a one-way valve is provided between the riser and the base, and the lower end of the one-way valve is detachably connected to the base; the one-way valve is located below the first three-way connection.

[0006] Preferably, the upper end of the riser is connected to the second tee through a joint.

[0007] Preferably, a floating plate is fixed to the outer periphery of the upper portion of the exhaust hose.

[0008] Preferably, the riser is a telescopic tube.

[0009] Preferably, the exhaust hose is a transparent tube.

[0010] Preferably, the portion of the exhaust hose located above the floating plate is a hard tube, a circular ring is fixed above the hard tube, and a plastic wire is fixed on the circular ring.

[0011] Beneficial effects of the utility model:

[0012] 1. Compared with the prior art, in the present invention, when the vehicle body gradually sinks, the air pressure between the interior of the vehicle body and the electrolyte increases, and the air is discharged through the exhaust hose, so that the electrophoretic liquid can smoothly reach the top of the vehicle body, solving the problem of poor electrophoresis on the top cover.

[0013] 2. Compared with the prior art, the present invention adopts a telescopic riser, which can be adjusted according to the height of the vehicle body to meet the electrophoresis requirements of different models.

[0014] 3. Compared with the prior art, the present invention fixes a float on the outer periphery of the upper portion of the exhaust hose to prevent the exhaust hose from falling into the electrothermal pool.

[0015] 4. Compared with the prior art, the present invention provides a hard tube, a circular plastic wire and other structures. When the exhaust hose is venting, the airflow blows the plastic wire upward. When the exhaust hose stops venting, the plastic wire naturally droops, making it easy to observe whether the exhaust hose has completed exhaust.

[0016] 5. Compared with the prior art, the present invention sets a one-way valve. When the vehicle body sinks, the one-way valve is closed to prevent the electrophoretic fluid from entering the column and the exhaust hose through the one-way valve, thereby facilitating exhaust. When the vehicle body moves upward after the electrophoresis is completed, the one-way valve opens, and the electrophoretic fluid inside the column and the hose is discharged through the one-way valve, thereby realizing the reuse of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] Figure 1 It is the overall structure diagram of the utility model.

[0018] The figure marks in the drawings of the specification include: base 1, bolt 2, one-way valve 3, riser 4, first tee 5, exhaust hose 6, connector 7, second tee 8, third tee 9, air inlet pipe 10, right-angle two-way 11, float 12, hard pipe 13, steel wire 14, ring 15, plastic wire 16. DETAILED DESCRIPTION

[0019] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0020] Example 1:

[0021] Painting exhaust tooling, such as Figure 1As shown, the apparatus comprises a base 1 fixed to the bottom of the electrothermal pool. A one-way valve 3, arranged vertically along its axis, is connected to the top end of the base 1 via bolts 2. A standpipe 4 is secured to the top end of the one-way valve 3. The bottom end of the standpipe 4 is connected to an exhaust hose 6 via a first tee 5. The top end of the exhaust hose 6 extends above the liquid level of the electrothermal pool. The top end of the standpipe 4 is detachably connected to a second tee 8 via a joint 7. The left and right ends of the second tee 8 are each connected to a third tee 9 via pipes. The end of the third tee 9, remote from the second tee 8, is connected to a right-angled two-way pipe 11 via pipes. An upwardly-oriented intake pipe 10 is connected to the vertical ends of the third tee 9 and the right-angled two-way pipe 11. In this embodiment, a float 12 is secured to the outer periphery of the top of the exhaust hose 6 to prevent it from falling into the electrothermal pool.

[0022] When the vehicle body descends to the point where the top of the vehicle body contacts the top of the air intake pipe 10, the air inside the vehicle body enters the riser 4 through the air intake pipe 10 and is then discharged through the exhaust hose 6. When the electrophoretic liquid rises to the top of the vehicle body, the electrophoretic liquid will enter the air intake pipe 10 and then be discharged through the exhaust hose 6. The exhaust hose 6 is a transparent pipe, which makes it convenient for the operator to observe in real time whether there is electrophoretic liquid overflow. If there is, it means that the electrophoretic liquid has completely covered the interior of the vehicle body.

[0023] The vertical tube 4 in this embodiment is a telescopic tube, which is convenient for matching with vehicles of different heights.

[0024] However, after a period of use, electrophoretic fluid adheres to the sidewalls of the exhaust hose 6, making it inconvenient to inspect. Therefore, in this embodiment, the portion of the exhaust hose 6 located above the float 12 is a hard tube 13. A circular ring 15 is fixed to the top of the hard tube 13 via a steel wire 14. A plastic wire 16 is fixed to the circular ring 15. When the exhaust hose 6 is venting, the airflow blows the plastic wire 16 upward. When the exhaust hose 6 stops venting, the plastic wire 16 naturally droops, making it easy to observe whether the exhaust hose 6 has completed venting. When the plastic wire 16 naturally droops after flying upward for a period of time, it indicates that the electrophoretic fluid has completely covered the interior of the vehicle body. At this time, since the circular ring 15 is a certain distance away from the upper end of the hard tube 13, the electrophoretic fluid will not adhere to the plastic wire 16, which will not affect the reuse of the plastic wire 16.

[0025] During the sinking process of the vehicle body, the one-way valve 3 is closed to prevent the electrophoretic fluid from entering the column and the exhaust hose 6 through the one-way valve 3, which facilitates exhaust. When the vehicle body moves upward after the electrophoresis is completed, the one-way valve 3 is opened, and the electrophoretic fluid inside the standpipe 4 and the hose is discharged through the one-way valve 3, realizing the reuse of the utility model.

[0026] The utility model is completely disassembled, which is convenient for cleaning and replacement of accessories.

[0027] The above is only a specific implementation method of the present invention, but the scope of protection of the present invention is not limited to this. Any technician familiar with the technical field can easily think of changes or replacements within the technical scope disclosed by the present invention, which should be included in the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
