Description

Technical Field

[0001] The utility model relates to the technical field of tooling cleaning, in particular to a rotary airbag sealing device. Background Art

[0002] When cleaning workpieces, the previous sealing device uses a sealing strip contact seal. The tooling basket contacts the sealing strip both in the rotating and stationary states. The tooling basket will rub against the sealing strip when rotating, thereby reducing the life of the sealing strip and increasing the power consumption of the cleaning machine.

[0003] At present, there are still some shortcomings in the rotary sealing method, such as incomplete sealing, high energy consumption, and rapid loss of sealing materials. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a rotating airbag sealing device, which can inflate the airbag to make the vertical plate and the partition plate reach a sealed state at the avoidance groove. When the cleaning tank rotates, the airbag deflates to release the contact seal, leaving movement space for the cleaning tank and reducing energy consumption.

[0005] The utility model is realized through the following technical solutions:

[0006] A rotating airbag sealing device is provided, which is installed between two adjacent cleaning tanks of numerical control cleaning equipment, and comprises a fixed vertical plate and a partition plate which rotates synchronously with the cleaning tank. An avoidance groove is provided on the vertical plate for the partition plate to pass through when rotating and the area is larger than the area of ​​the partition plate.

An airbag is provided in the airbag mounting groove, and the airbag can be filled in the airbag mounting groove by inflating and deflating air to switch the sealing state between the vertical plate and the partition plate.

[0007] Furthermore, the airbag mounting seat includes two transverse U-shaped plates, a positioning transverse plate is vertically connected between the two transverse U-shaped plates, the airbag mounting groove is formed between the transverse U-shaped plates below the positioning transverse plate, and the two transverse U-shaped plates are respectively provided with connecting through holes above the positioning transverse plate, and long nut sleeves are arranged between the through holes, which are connected to the vertical plate with screws.

[0008] The airbag mounting seat is formed by connecting two horizontal U-shaped plates with a positioning horizontal plate. Its cross-section is H-shaped. The lower part of the H forms an airbag mounting groove for installing the airbag. The upper horizontal U-shaped plate has a connecting through hole, which is connected to the vertical plate with screws and long nuts for fixed installation.

[0009] Furthermore, the partition is rectangular and two outer corners away from the central axis of rotation are processed with arc chamfers matching the inner shape of the transverse U-shaped plate.

[0010] The two rectangular corners of the partition are chamfered with arcs to adapt to the shape of the airbag mounting seat, so that the two can fit tightly together to achieve sealing.

[0011] Furthermore, the airbag is connected to an air nozzle, a mounting hole is opened on one of the transverse U-shaped plates and an L-shaped threaded coupling is installed in the mounting hole, one end of the threaded coupling is connected to the air nozzle, and the other end is connected to the inflation and deflation device through an air pipe.

[0012] An air nozzle is arranged on the airbag, and the airbag is inflated and deflated by using the inflation and deflation device in conjunction with the air pipe and the L-shaped threaded two-way valve to facilitate the switching of the sealing state.

[0013] Furthermore, the cross-section of the airbag is a rounded rectangle with a cavity in the middle.

[0015] Beneficial effects of the utility model:

[0016] In the utility model, the sealing of the cleaning tank when rotating and when stationary is differentiated. By arranging an airbag mounting plate to cooperate with the airbag, the inflation and deflation operation of the airbag can be controlled by the inflation and deflation device. When the cleaning tank rotates, the airbag is deflated, so that the avoidance grooves of the partition and the vertical plate do not contact and rub, thereby reducing movement resistance and reducing power consumption of the cleaning machine; and when the cleaning tank is stationary, the airbag is inflated, so that the airbag is filled in the avoidance grooves of the partition and the vertical plate, achieving a sealed state and improving the sealing performance.

[0026] In order to clearly illustrate the technical features of this solution, this solution is described below through a specific implementation method.

[0027] A rotary airbag sealing device is installed between two adjacent cleaning tanks 3 of a numerically controlled cleaning device, and comprises a fixed vertical plate 2 and a partition plate 4 which rotates synchronously with the cleaning tank 3. The vertical plate 2 is provided with an avoidance groove which is larger than the area of ​​the partition plate 4 for the partition plate 4 to pass through when rotating. The vertical plate 2 is connected to a sealing member 5 which matches the shape of the partition plate 4 at the inner periphery of the avoidance groove. The sealing member 5 comprises an airbag mounting seat. An airbag mounting groove is formed on a side of the airbag mounting seat which faces the edge of the partition plate 4. An airbag 10 is arranged in the airbag mounting groove, which can be filled with air by inflating and deflating to switch the sealing state between the vertical plate 2 and the partition plate 4.

[0028] The airbag mounting seat includes two transverse U-shaped plates 6, between which a positioning transverse plate 12 is vertically connected, and an airbag mounting groove is formed between the transverse U-shaped plates 6 below the positioning transverse plate 12. The two transverse U-shaped plates 6 are respectively provided with connecting through holes above the positioning transverse plate 12, and a long nut sleeve 8 is arranged between the through holes, and is connected to the vertical plate 2 with screws. The partition plate 4 is rectangular and the two outer corners away from the rotation center axis 1 are processed with arc chamfers matching the inner shape of the transverse U-shaped plate 6.

[0029] The airbag 10 is connected to an air nozzle 11, a mounting hole is opened on one of the transverse U-shaped plates 6, and an L-shaped threaded coupling 9 is installed in the mounting hole. One end of the threaded coupling 9 is connected to the air nozzle 11, and the other end is connected to the inflation and deflation device through an air pipe.

[0030] The cross-section of the airbag 10 is a rounded rectangle with a cavity in the middle. A plurality of airbag positioning through holes are formed on a side of the airbag 10 facing the positioning cross plate 12. The positioning cross plate 12 has opposite cross plate positioning through holes corresponding to the airbag positioning through holes. An airbag fixing plate 13 is passed through the cavity of the airbag 10. The airbag fixing plate 13 has threaded holes facing the cross plate positioning through holes and the airbag positioning through holes, and screws are threadedly connected in the three holes.

[0031] When installing the utility model, first pass the airbag fixing plate 13 on the airbag 10, and fix the airbag fixing plate 13 on the positioning horizontal plate 12 by screws, then connect the airbag mounting seat to the avoidance groove of the vertical plate 2 through the hexagonal long nut sleeve 8 in cooperation with the hexagon socket cylindrical head screw 7, connect the air nozzle 11 in the middle of the airbag 10, and connect the inflation and deflation device through the L-shaped threaded two-way 9 in cooperation with the air pipe.

[0032] When the airbag 10 is inflated by using the inflation and deflation device, the airbag 10 expands so that the vacant position between the two airbag mounting plates 6 is filled, thereby achieving sealing of the vertical plate 2 and the partition 4 in the avoidance groove. When the cleaning groove 3 rotates, the inflation and deflation device deflates the airbag 10, leaving rotation space for the partition 4 when passing through the avoidance groove, so that it will not rub against the airbag 10, thereby greatly improving the service life of the airbag 10 and reducing the power consumption of the cleaning machine.
