[0063] The structures of the first turret 1000, the rotating disc material transferring mechanism 3000, and the second turret 2000 will be further described as follows: ​​

[0064] First turret 1000

[0065] like Figures 11-19 As shown, the first turret 1000 includes a first turret body 1001, from which a first turntable 1002, a second turntable 1003, a third turntable 1004, and a fourth turntable 1005 are arranged sequentially from top to bottom. A main body plug clamping and pressing mechanism 1010 and an air bag clamping and pushing mechanism 1020 are installed vertically on the first turret body 1001. The main body plug clamping and pressing mechanism 1010 and the air bag clamping and pushing mechanism 1020 are used to clamp the main body plug 1 and the air bag 2, respectively. The air bag clamping and pushing mechanism 1020 pushes the air bag 2 upwards to insert it into the main body plug 1 to form... Figure 4 The semi-finished material 4, and while the air bag clamping and pushing mechanism 1020 pushes upward, the main body plug clamping and pressing mechanism 1010 presses down on the upper end face of the main body plug.

[0066] The specific structure of the first turret 1000 is explained below:

[0067] 1) Main body plug clamping and pressing mechanism 1010

[0068] The main body plug clamping and pressing mechanism 1010 is provided with a first cam ring 1011, a first pressing mechanism 1012, and a first clamping mechanism 1013 sequentially from top to bottom, such as Figure 11 As shown.

[0069] The first cam ring 1011 is statically mounted on the first turret body 1001, and the outer side wall of the first cam ring 1011 is provided with cam grooves 1011-1 of varying heights along the circumferential direction.

[0070] The first clamping mechanism 1012 and the first clamping mechanism 1013 are respectively mounted on the first turntable 1002 and the second turntable 1003. The first clamping mechanism 1012 and the first clamping mechanism 1013 each include a plurality of first downward pressing rods 1012-1 (e.g., ...) circumferentially arranged on the first turntable 1002 and the second turntable 1003. Figure 12 The first turret body 1001 rotates with the first turret body 1001 and is equipped with several first grippers 1013-1. The first downward push rod 1012-1 moves up and down in conjunction with the first cam ring 1011 during rotation. The outer edge of the second turntable 1003 has a second turntable opening groove 1003-1 to support the main body plug 1, and the lower half of the main body plug 1 is held by the first grippers 1013-1 located on the lower surface of the second turntable 1003. (The text abruptly ends here, likely due to an incomplete translation or source material.) Figure 1 As shown, the main body plug 1 is equipped with a protruding ring 1-1 that can be hung on the second turntable 1003. Simultaneously, the subsequent semi-finished material 4 can also be hung on the tenth and sixth turntables via the protruding ring 1-1. Figure 12Only one of the first lower push rod 1012-1 and the first upper push rod 1022-1 is shown by omitting drawing, and in the actual product, the first turret is provided with a plurality of first lower push rods 1012-1 and first upper push rods 1022-1 arranged in a circle.

[0071] As shown in Figure 15 The first lower push rod 1012-1 is provided with a first guide rail support 1012-2, a first push rod 1012-3, and a first spring 1012-4. The first guide rail support 1012-2 is axially fixed on the first turret body 1001 or the second turret body 2001. The first push rod 1012-3 is slidably installed on the first guide rail support 1012-2. The upper end of the first push rod 1012-3 is provided with a first roller 1012-5 that rolls with the cam groove 1011-1. The lower end of the first push rod 1012-3 is used with the lower body plug 1 or the semi-finished material 4. The bottom end of the first spring 1012-4 is connected with the first push rod 1012-3, and the top end of the first spring 1012-4 is connected with the first rotary disc 1002 or the fifth rotary disc 2002. The first spring 1012-4 provides upward pulling force for the first push rod 1012-3 to make the first roller 1012-5 always roll along the inner upper surface of the cam groove 1011-1.

[0072] 2) Air pocket clamping and pushing mechanism 1020

[0073] The air pocket clamping and pushing mechanism 1020 is sequentially provided with a second cam ring 1021, a first upper pushing mechanism 1022, and a second clamping mechanism 1023 from bottom to top.

[0074] The second cam ring 1021 is statically installed on the first turret body 1001, and the upper end surface of the second cam ring 1021 is provided with cam surfaces 1021-1 of different heights in the circumferential direction.

[0075] The first upper pushing mechanism 1022 and the second clamping mechanism 1023 are respectively installed on the fourth rotary disc 1005 and the third rotary disc 1004. The first upper pushing mechanism 1022 and the second clamping mechanism 1023 respectively include a plurality of second clamping jaws 1023-1 and a plurality of first upper push rods 1022-1 arranged in the circumferential direction on the fourth rotary disc 1005 and the third rotary disc 1004. The third rotary disc 1004 is provided with a circle of third rotary disc opening grooves 1004-1 for accommodating the air pocket 2, and the lower half of the air pocket 2 is clamped by the second clamping jaws 1023-1 located on the lower surface of the third rotary disc 1004. The first upper push rod 1022-1 floats up and down in cooperation with the second cam ring 1021 during the rotation of the first turret body 1001.

[0076] As shown in Figures 16-17As shown, the first upper push rod 1022-1 is equipped with a linear bearing 1022-2. The linear bearing 1022-2 is connected to the fourth turntable 1005 or the eighth turntable 2005 via an upper mounting plate 1022-3. The bottom of the linear bearing 1022-2 is equipped with a lower fixing plate 1022-4. A roller seat 1022-5 is installed at the bottom of the lower fixing plate 1022-4. The roller seat 1022-5 is equipped with a second roller 1022-6 that rolls with the cam surface 1021-1. The bottom end of the piston rod 1022-8 of the linear bearing 1022-2 and the lower fixing plate 1022-4 are connected to the lower fixing plate 1022-5. The fixed plate 1022-4 is fixedly connected, and the upper end of the piston rod 1022-8 slides through the upper mounting plate 1022-3 and is fixedly connected to the upper top plate 1022-9. The upper top plate 1022-9 is used to support the air bag 2 or the long tube 3. A second spring 1022-7 is sleeved on the piston rod 1022-8 between the upper mounting plate 1022-3 and the lower fixed plate 1022-4. The second spring 1022-7 provides downward pressure to the roller seat 1022-5 so that the second roller 1022-6 always rolls along the upper surface of the cam surface 1021-1.

[0077] like Figure 8 As shown, a first sector-shaped cam block 1004-2 and a first sector-shaped limiting plate 1004-3 are stationarily installed around the third turntable 1004. A first turret inlet and a first turret outlet are provided between the two ends of the first sector-shaped cam block 1004-2 and the first sector-shaped limiting plate 1004-3. The first turret inlet is connected to the air bag conveying device 1050, and the first turret outlet is connected to the turntable material transfer mechanism 3000. The first sector-shaped limiting plate 1004-3 is located in the radially outward extension area of ​​the axial projection area of ​​the sector magnet 1031, which ensures that the clamping areas of the main body plug 1 and the air bag 2 are the same, avoiding the problem that the clamping states of the main body plug 1 and the corresponding air bag 2 are not synchronized. That is, when the main body plug 1 is clamped, the air bag 2 is also in a clamping state. Similarly, when the first gripper 1013-1 releases the main body plug 1, the air bag 2 is also released by the second gripper 1023-1.

[0078] The second jaw 1023-1 is a spring jaw comprising a first Y-shaped jaw body 1023-2 and a third spring 1023-3, the first Y-shaped jaw body 1023-2 is horizontally rotatably installed at the lower surface of the third turntable 1004, the front end of the first Y-shaped jaw body 1023-2 is provided with a bifurcated part with a long branch and a short branch, the end of the long branch 1023-5 is provided with a third roller 1023-4 for cooperating with the first fan-shaped cam block 1004-2, the rear end of the first Y-shaped jaw body 1023-2 is connected with the third spring 1023-3, the other end of the third spring 1023-3 is installed at the inner side of the third turntable 1004. When the third turntable 1004 rotates to the position where the second jaw 1023-1 contacts the first fan-shaped cam block 1004-2, the second jaw 1023-1 is opened, and when the third turntable 1004 rotates to the position where the second jaw 1023-1 is away from the first fan-shaped cam block 1004-2, the second jaw 1023-1 is closed to clamp the air bag 2 in the third turntable opening groove 1004-1, at this time, the air bag 2 is extruded by the first short bifurcated part 1023-6 relative to the outside of the third turntable opening groove 1004-1 to be clamped and fixed at the third turntable opening groove 1004-1. The first fan-shaped limiting plate 1004-3 plays a circumferential limiting role to avoid the air bag 2 from falling off during the rotation of the turret.

[0079] In the mold closing position area of the first turret 1000, the first cam ring 1011 is concave downward and the second cam ring 1021 is convex upward, so that the first downward pressing push rod 1012-1 is floated downward and is pressed tightly on the upper end surface of the main body plug 1 clamped by the first jaw 1013-1, and the first upward pushing rod 1022-1 is floated upward to push the air bag 2 clamped by the second jaw 1023-1 upward and insert it into the main body plug 1 to form the semi-finished material piece 4.

[0080] As Figure 11 and Figure 12As shown, the ninth rotating disc 1006 is fixedly installed on the first turret body 1001. The electromagnetic control mechanism 1030 is arranged on the first turret body 1001 to control the opening and closing of each first jaw 1013-1. The electromagnetic control mechanism 1030 includes a sector magnet 1031 and a plurality of electromagnetic valves 1032 arranged in the circumferential direction of the ninth rotating disc 1006. The sector magnet 1031 is fixedly installed on the first turret body 1001. The electromagnetic valves 1032 on the first turret body 1001 correspond to the first jaws 1013-1 in the axial direction and are electrically connected. When the electromagnetic valve 1032 rotates to the sector magnet 1031 area, the electromagnetic valve 1032 senses the magnetic field and closes the corresponding first jaw 1013-1. When the electromagnetic valve 1032 leaves the sector magnet 1031 area, the electromagnetic valve 1032 opens the corresponding first jaw 1013-1. It should be noted that the mold closing position area of the first turret 1000 is located in the axial projection area of the sector magnet 1031, so as to ensure that the first jaw 1013-1 is always in the closed state when the first turret 1000 is closed.

[0081] In addition, as shown in Figure 7 and Figure 9 , the first turret 1000 is connected with the main body plug feeding device 1040 and the gas pocket conveying device 1050. The main body plug 1 is sent into the second rotating disc opening slot 1003-1 in front of the sector magnet 1031 by the main body plug feeding device 1040. The gas pocket 2 is sent into the third rotating disc opening slot 1004-1 behind the first cam block 1004-2 (as shown in Figure 8 ) by the gas pocket conveying device 1050 connected with the starting position of the first cam block 1004-2.

[0082] It should be noted that the front side and the rear side in this article are defined according to the rotating direction of the turret.

[0083] The second turret 2000

[0084] As shown in Figures 20-23 , the second turret 2000 is provided with a second turret body 2001. The fifth rotating disc 2002, the sixth rotating disc (not shown in the figure), the seventh rotating disc 2004 and the eighth rotating disc 2005 are arranged in sequence on the second turret body 2001.

[0085] The material clamping and pressing down mechanism 2010 and the long tube clamping and upward lifting mechanism 2020 are installed on the second turret body 2001. The material clamping and pressing down mechanism 2010 and the long tube clamping and upward lifting mechanism 2020 are respectively used for clamping the semi-finished material 4 and the long tube 3.

At the same time, the long tube clamping and upward lifting mechanism 2020 is upwardly lifted, the material clamping and pressing down mechanism 2010 is pressed down on the upper end surface of the semi-finished material 4.

[0088] In the present application, the material piece clamping and pressing mechanism 2010 on the second turret 2000 is basically the same as the body plug clamping and pressing mechanism 1010 of the first turret 1000, the difference lies in that the body plug clamping and pressing mechanism 1010 is used for clamping and pressing the body plug 1, while the material piece clamping and pressing mechanism 2010 is used for clamping and pressing the semi-finished material piece 4. However, the top of the semi-finished material piece 4 is still the body plug 1, so the body plug clamping and pressing mechanism 1010 of the first turret 1000 can be directly applied to the material piece clamping and pressing mechanism 2010 of the second turret 2000, and the structural description of the material piece clamping and pressing mechanism 2010 will not be repeated here.

[0089] Similarly, the long pipe clamping and lifting mechanism 2020 on the second turret 2000 is also basically the same as the air bag clamping and pushing mechanism 1020 of the first turret 1000, and therefore the structural description of the long pipe clamping and lifting mechanism 2020 will not be repeated here.

[0090] Similarly, the second turret 2000 is also provided with the same ninth turntable 1006 and electromagnetic control mechanism 1030 as those on the first turret 1000, and the structure and function are also completely the same. The opening and closing of the third clamping jaw 2013-1 is controlled by the electromagnetic valve 1032 on the second turret 2000 sweeping the fan-shaped magnet 1031, and then the semi-finished product 4 is clamped or released. Among them, the mold closing position of the second turret 2000 is located in the axial projection area of the fan-shaped magnet 1031, so as to ensure that the third clamping jaw 2013-1 is always in a closed state when the second turret 2000 is closed. 1) When the electromagnetic valve 1032 rotates to the area of the fan-shaped magnet 1031, the electromagnetic valve 1032 senses the magnetic field and closes the corresponding third clamping jaw 2013-1. When the electromagnetic valve 1032 leaves the area of the fan-shaped magnet 1031, the electromagnetic valve 1032 opens the corresponding third clamping jaw 2013-1.

[0091] The mold closing principle of the second turret 2000 is also the same as that of the first turret 1000. In the mold closing position area of the second turret 2000, the third cam ring 2011 is concave downward and the fourth cam ring 2021 is convex upward, so that the second lower push rod 2012-1 is floated downward and pressed on the upper end surface of the semi-finished product 4 clamped by the third clamping jaw 2013-1, and at the same time the second upper push rod 2022-1 is floated upward to insert the long tube 3 in the seventh turntable open slot 2004-1 upward and insert into the semi-finished product 4 to form the nozzle assembly 5.

[0092] In addition, as shown in Figure 7 and Figure 9 , the second turret 2000 is also connected with a long tube conveying device 2040 and a material taking device 2050. The long tube conveying device 2040 sends the long tube 3 to the seventh turntable open slot 2004-1, and the material taking device 2050 takes away the nozzle assembly 5 assembled on the second turret 2000.

[0093] As shown in Figure 23 , the material taking device 2050 is provided with a Y-shaped guide plate 2051, which is located at the terminal end of the third fan-shaped limiting plate 303 in the rotation direction. The end of the Y-shaped guide plate 2051 is provided with a blowing device. The nozzle assembly 5 on the turntable is shaken by blowing out gas through the blowing device. The second turret cooperates with the Y-shaped guide plate 2051 in the rotation process, and the nozzle assembly 5 is conveyed to the discharge track 2052 through the Y-shaped guide plate 2051 to complete the discharge.

[0094] Turntable material rotating mechanism 3000

[0095] As shown in Figure 10As shown, the rotary disc material rotating mechanism 3000 is provided with a tenth rotary disc 3001, and the tenth rotary disc 3001 is provided with a plurality of tenth rotary disc opening slots on the outer edge. A plurality of fourth clamping jaws 3004 are installed on the tenth rotary disc 3001. The rotation directions of the tenth rotary disc 3001 and the first turret 1000 and the second turret 2000 on both sides are opposite.

[0096] A second fan-shaped cam block 3002 and a third fan-shaped limiting plate 3003 are fixedly installed on the periphery of the tenth rotary disc 3001. The two ends of the second fan-shaped cam block 3002 and the third fan-shaped limiting plate 3003 are provided with a rotary disc material rotating mechanism inlet and a rotary disc material rotating mechanism outlet. The rotary disc material rotating mechanism inlet is connected with the first turret outlet, and the rotary disc material rotating mechanism outlet is connected with the second turret 2000.

[0097] The tenth rotary disc 3001 is provided with a plurality of tenth rotary disc opening slots, such as Figure 24 As shown, the fourth clamping jaw 3004 is a spring clamping jaw comprising a second Y-shaped jaw body 3004-1 and a fourth spring 3004-6. The second Y-shaped jaw body 3004-1 is horizontally rotatably installed on the tenth rotary disc 3001. The second Y-shaped jaw body 3004-1 is provided with a bifurcated part with a long branch and a short branch. The second long bifurcated part 3004-2 and the second short bifurcated part 3004-3 are flush. The second long bifurcated part 3004-2 is provided with a fourth roller 3004-4 for cooperating with the second fan-shaped cam block 3002. In the rotation direction, the second long bifurcated part 3004-2 is located in front of the second short bifurcated part 3004-3. An auxiliary clamping arm 3004-5 is fixedly installed on the second long bifurcated part 3004-2 and is located at a different height from the second short bifurcated part 3004-3. The other end of the auxiliary clamping arm 3004-5 extends to the second short bifurcated part 3004-3. The rear end of the second Y-shaped jaw body 3004-1 is connected with the fourth spring 3004-6, and the other end of the fourth spring 3004-6 is installed on the tenth rotary disc 3001 near the shaft center of the second Y-shaped jaw body 3004-1.

[0098] As shown, Figure 25 The other side of the second short bifurcated part 3004-3 relative to the second long bifurcated part 3004-2 is provided with a first clamping notch 3004-31, and the end of the auxiliary clamping arm 3004-5 is provided with a second clamping notch 3004-51 on the same side as the first clamping notch 3004-31. In the rotation direction, the first clamping notch 3004-31 and the second clamping notch 3004-51 are located on the front side of the second Y-shaped jaw body 3004-1. By simultaneously pressing the different heights of the main body plug 1 through the second short bifurcated part 3004-3 and the auxiliary clamping arm 3004-5, the clamping effect is more stable.

[0099] When the tenth rotating disc 3001 rotates to the fourth roller 3004-4 contacts the second sector cam block 3002, the fourth clamp jaw 3004 is in an open state; when the tenth rotating disc 3001 rotates to the fourth roller 3004-4 leaves the second sector cam block 3002, the fourth spring 3004-6 pulls the second Y-shaped jaw body 3004-1 to rotate and reset, and the short bifurcated part 3004-3 rotates towards the opening slot of the tenth rotating disc to clamp the semi-finished material piece 4 in the opening slot of the tenth rotating disc, at this time, the main body plug 1 of the semi-finished material piece 4 is simultaneously extruded by the second short bifurcated part 3004-3 and the auxiliary clamping arm 3004-5 relative to the outside of the opening slot of the tenth rotating disc to be clamped and fixed at the opening slot of the tenth rotating disc.

[0100] In the rotating direction, the fourth clamp jaw 3004 sequentially circulates through the first turret discharge port, the third sector limiting plate 3003, the second turret feed port and the second sector cam block 3002.

[0101] The structure and working principle of the fourth clamp jaw 3004 are basically the same as those of the second clamp jaw 1023-1 on the first turret, and specific reference can be made to the related description of the second clamp jaw 1023-1 above.

[0102] The working process of the present application is briefly described as follows:

[0103] 1) The main body plug 1 and the air pocket 2 are respectively conveyed to the first turret 1000 and clamped by the first clamp jaw 1013-1 and the second clamp jaw 1023-1. Take the air pocket conveying device 1050 as an example to describe the conveying of the air pocket 2: the air pocket conveying device 1050 sends the air pocket 2 to the first turret feed port (the first turret feed port is located on the rear side of the end point of the first sector cam block 1004-2), when the second clamp jaw 1023-1 cooperates with the first sector cam block 1004-2, the second clamp jaw 1023-1 is in an open state. With the rotation of the turret, the second clamp jaw 1023-1 is separated from the first sector cam block 1004-2, and under the action of the third spring 1023-3, the second clamp jaw 1023-1 resets and clamps the air pocket 2 in the third rotating disc opening slot 1004-1.

[0104] When the first turret 1000 rotates to the mold closing position, the first downward floating push rod 1012-1 is floated downward and tightly pressed on the upper end surface of the main body plug 1, and at the same time, the first upward floating push rod 1022-1 is floated upward to push the air pocket 2 upward and insert it into the main body plug 1 to form the semi-finished material piece 4.

[0105] 2) The semi-finished material piece 4 on the first turret 1000 is taken away by the rotating disc rotating mechanism 3000 and transferred to the second turret 2000. On the second turret 2000, the semi-finished material piece 4 is clamped by the third clamp jaw 2013-1, and the long pipe 3 is sent into the seventh rotating disc opening slot 2004-1 of the second turret 2000 by the long pipe conveying device 2040.

[0106] 3)Second turret 2000 rotates to the mold closing position, the second lower push rod 2012-1 floats down and presses on the end face of the semi-finished material 4, and at the same time the second upper push rod 2022-1 floats up and inserts the long tube 3 into the semi-finished material 4 to form the nozzle assembly 5.

[0107] 4)With the continuous rotation of the second turret 2000, when the nozzle assembly 5 rotates to the material taking device 2050 position, the Y-shaped guide plate 2051 of the material taking device 2050 constantly blows gas, so that the nozzle assembly 5 is separated from the turret and flows to the discharge track 2052 under the action of the Y-shaped guide plate 2051 to finally complete the discharge.

[0108] In steps 1 and 3, when the solenoid valve 1032 on the first turret 1000 or the second turret 2000 rotates to the area of the sector magnet 1031, the solenoid valve 1032 senses the magnetic field and closes the corresponding first jaw 1013-1 or third jaw 2013-1. When the solenoid valve 1032 of the first turret 1000 leaves the area of the sector magnet 1031, the solenoid valve 1032 opens the corresponding first jaw 1013-1, and the first turret 1000 is transferred away by the turntable material transfer mechanism 3000; when the solenoid valve 1032 of the second turret 2000 leaves the area of the sector magnet 1031, the solenoid valve 1032 opens the corresponding third jaw 2013-1, so that the material taking device 2050 takes away the nozzle assembly 5 assembled on the second turret 2000.
