Background Art

[0002] In the prior art, for a large amphibious aircraft to achieve functions such as wading, water intake, water storage, and water dropping, the sealing performance requirements for the airframe are very strict, and the amount of sealant used is huge.

[0003] Before use, the whole tube of sealant needs to be sub-packed separately according to the usage requirements. At present, manual sub-packaging is used for sealant sub-packaging. Manual sub-packaging cannot be accurate to the designed sub-packaging amount, and due to the high viscosity of the sealant, the sub-packaging is time-consuming and laborious. Moreover, with manual sub-packaging, the sub-packaging efficiency is slow, the sub-packaging amount is too small to meet the production usage amount, and the effective sealing effect on the airframe cannot be achieved after use; while when the manual sub-packaging amount is too much, the sealant cannot be used continuously after curing, resulting in a large amount of waste, and the excess sealant will cause environmental pollution.

Correspondingly, the turntable drive assembly drives the rotating disk to rotate one station, and the glue cup at the next station is located at the sealant injection position and receives the sealant injection after the injection feeding mechanism drives the pneumatic sealant injection mechanism to move downward again.

[0009] Preferably, the pneumatic sealant injection mechanism includes an injection cylinder, an injection push rod, an injection barrel, an outer sleeve, a sealant barrel, and an outer sleeve fixing seat.

[0012] Preferably, the injection feeding mechanism includes a magnetic rail cylinder, a stroke slider, an upper limit travel switch, and a lower limit travel switch. The pneumatic sealant injection mechanism and the stroke slider are installed on the magnetic rail cylinder. The upper limit travel switch and the lower limit travel switch are respectively installed on the frame base on the upper and lower sides of the stroke slider.

Four groups of glue cups automatically switched by a rotary cylinder are arranged below the glue injection nozzle. The magnetic rail cylinder of the glue injection feeding mechanism moves up and down. When injecting glue, it moves downward to the position where the lower limit travel switch is turned on to start injecting glue.

The corresponding turntable driving assembly 9 drives the rotating disk 7 to rotate one station, and the glue receiving cup 8 at the next station is located at the glue discharging station and receives the glue injection after the glue injection feeding mechanism 5 drives the pneumatic glue injection mechanism 6 to move down again.

[0029] Continue as Figures 1 to 5As shown, the pneumatic glue injection mechanism 6 includes a glue injection cylinder 60, a glue injection push rod 61, a glue injection barrel 62, an outer sleeve 63, a sealing glue barrel 64 and an outer sleeve fixing seat 65. The sealing glue barrel 64 is used to contain the sealant to be packaged; the glue injection cylinder 60 and the glue injection push rod 61 are sleeved in the glue injection barrel 62, and the glue injection cylinder 60 pushes the glue injection push rod 61 connected to the lower end to move up and down; the bottom end of the outer sleeve 63 is fixed on the outer sleeve fixing seat 65 and is integrally installed on the glue injection feeding mechanism 5. The glue feeding mechanism 5 is installed on the front side of the frame seat 1; the sealant cylinder 64 is sleeved in the outer sleeve 63, and the glue injection nozzle 66 for the sealant outlet connected to the bottom end of the sealant cylinder 64 passes through the outer sleeve fixed seat 65 and moves downward to the glue outlet station; the lower end of the glue injection cylinder is rotated and locked to the top of the outer sleeve 63, and the corresponding glue injection push rod 61 is slidably inserted on the top of the sealant cylinder 64; the glue injection cylinder 60 drives the glue injection push rod 61 to move downward to squeeze the sealant in the sealant cylinder 64 from the glue injection nozzle 66. Among them, the two sides of the lower part of the glue injection cylinder 62 are symmetrically provided with locking columns 67 protruding from the outer wall, and the two sides of the top of the corresponding outer sleeve 63 are axially opened with "L"-shaped lock grooves 68 that slide with the locking columns 67 and are used to lock the glue injection cylinder on the outer sleeve 63 after rotation.

[0030] Continue as Figures 1 to 5 As shown, the glue injection and feeding mechanism 5 includes a magnetic rail cylinder 50, a stroke slider 51, an upper limit stroke switch 52 and a lower limit stroke switch 53. The pneumatic glue injection mechanism 6 and the stroke slider 51 are installed on the magnetic rail cylinder 50. The upper limit stroke switch 52 and the lower limit stroke switch 53 are correspondingly installed on the frame seat 1 on the upper and lower sides of the stroke slider 51; the magnetic rail cylinder 50 drives the stroke slider 51 to touch the lower limit stroke switch 53 to stop moving downward, and the corresponding pneumatic glue injection mechanism 6 moves downward to the glue discharging station, and the magnetic rail cylinder 50 drives the stroke slider 51 to touch the upper limit stroke switch 52 to stop moving upward, and the corresponding pneumatic glue injection mechanism 6 moves upward to the glue receiving stop position.

[0031] like Figure 1 , Figure 2 and Figure 5 As shown, the external gas source pipeline connected to the glue injection cylinder 60 is also connected to a filter 10 installed on the side wall of the frame seat 1 for filtering the compressed gas entering. The upper front of the frame seat 1 is also provided with a plurality of glue injection buttons 11 for users to select different glue injection amounts to control the glue injection cylinder 60 to quantitatively extrude a corresponding amount of sealant. In this embodiment, 5 grams, 10 grams, 15 grams, 20 grams, 25 grams and 30 grams of glue injection buttons 11 are respectively provided. An emergency stop button 12 and two start buttons 13 for emergency control of the entire machine are also installed on the front side of the frame seat 1.

[0032] During operation, the sealant cartridge 64 with the glue injection nozzle 66 is inserted downward into the outer sleeve 63. The locking post 67 at the lower part of the glue injection cylinder 62 is engaged with the "L"-shaped locking groove 68 at the upper end of the outer sleeve 63. After the engagement, the glue injection push rod 61 inside the glue injection cylinder 62 presses the sealant cartridge 64 to ensure a fixed glue pressing space.

[0033] After the sealant cartridge 64 is fixed, press the glue injection button 122 corresponding to the required glue injection amount according to the designed glue injection amount.

First, the magnetic rail cylinder 50 moves downward through the outer sleeve fixing seat 65. Since the stroke slider 51 is fixed on the outer sleeve fixing seat 65, it moves downward synchronously with the outer sleeve fixing seat 65. When the stroke slider 51 moves downward to the lower limit travel switch 53 and is turned on, the solenoid valve group 2 stops the air source output, and the magnetic rail cylinder 50 stops and remains. Then, the PLC module 3 controls the second solenoid valve on the solenoid valve group 2 to inject air into the glue injection cylinder 60 inside the glue injection cylinder 62, controlling the piston shaft of the glue injection cylinder 60 to extend, driving the glue injection push rod 61 to move downward. After the internal space of the sealant cartridge 64 is squeezed, the sealant is extruded from the glue injection nozzle 66. After the sealant is discharged, it falls into the glue receiving cup 8. When the glue injection amount reaches the designed glue discharge amount, on the one hand, the PLC module 3 controls the second solenoid valve on the solenoid valve group 2 to act, causing the magnetic rail cylinder 50 to move upward. When the stroke slider 51 moves upward and the upper limit travel switch 52 is turned on, the magnetic rail cylinder 50 stops and remains. On the other hand, the PLC module 3 controls the third solenoid valve of the solenoid valve group 2 to act, causing the rotary cylinder 90 to rotate counterclockwise by 90 degrees. The rotary cylinder 90 drives the rotary disk 7 to rotate synchronously through the transmission belt. When the rotation stops, the glue receiving cup 8 filled with the sealant is taken out from the rotary disk 7, and the glue receiving cup 8 is reset, and then the sealant with different doses can be sub-packaged repeatedly.
