Description

Technical Field

[0001] This invention relates to a nozzle assembly production line, specifically to a material conveying system for nozzle assemblies in a dual-turret processing production line. Background Technology

[0002] Figure 5 As a component of a nozzle in the prior art, it is composed of Figure 1 The main body plug 1 shown Figure 2 The air bag 2 shown is Figure 3 The nozzle assembly consists of a long tube 3 as shown. Currently, the assembly of this nozzle assembly is done manually, that is, by manually inserting the air bag 2 upwards into the main body plug 1 to form... Figure 4 The semi-finished material 4 is then assembled with the long tube 3 to form Figure 5 The nozzle assembly 5 is inefficient and requires considerable effort.

[0003] Currently, the applicant has developed a turret assembly system that assembles the main body plug 1, air tank 2, and long tube 3 together. The turret assembly system includes a first turret 1000 and a second turret 2000, through which the main body plug 1, air tank 2, and long tube 3 are assembled. However, since the first turret 1000 and the second turret 2000 are constantly rotating during operation, how to ensure material conveying is completed without stopping the machines, thereby further improving production efficiency, is a problem we need to consider. Summary of the Invention

[0004] This invention provides a feeding system for nozzle assemblies in a dual-turret processing production line. The system allows for real-time feeding and transfer of materials without stopping the first and second turrets, aiming to improve processing efficiency. The specific solution is as follows:

[0005] A feeding system for a nozzle assembly in a dual-turret processing production line is provided. The nozzle assembly is composed of a main plug, an air chamber, and a long tube. The dual-turret processing production line includes a first turret and a second turret. The first turret is equipped with a rotary main plug clamping and pressing mechanism and an air chamber clamping and pushing mechanism. The air chamber clamping and pushing mechanism pushes the air chamber upward to insert it into the main plug to form a semi-finished material. The second turret is equipped with a rotary material clamping and pressing mechanism and a long tube clamping and pushing mechanism. The long tube clamping and pushing mechanism pushes the long tube upward to insert it into the semi-finished material to form the nozzle assembly. The feeding system includes a main plug feeding device, an air chamber conveying device, a rotary material transfer mechanism, a long tube conveying device, and a material picking device.

[0006] The main plug feeding device is connected to the first turret, and the main plug is transported to the main plug clamping and pressing mechanism by the main plug feeding device.

[0007] The air bag conveying device is connected to the first turret, and the air bag is conveyed to the air bag clamping and pushing mechanism by the air bag conveying device.

[0008] The rotary material transfer mechanism is connected between the first and second turrets and rotates in the opposite direction to both the first and second turrets on either side. The mechanism includes a tenth turret, with a second sector-shaped cam block surrounding it. Several fourth grippers are located on the edge of the tenth turret for holding semi-finished materials. The two ends of the second sector-shaped cam block are respectively close to the discharge port of the first turret and the inlet of the second turret.

[0009] The fourth gripper is a spring gripper. When the spring gripper contacts the second sector-shaped cam block, the spring gripper is in the open state. The turntable material transfer mechanism receives the semi-finished material from the discharge port of the first turret, or transfers the semi-finished material on the turntable material transfer mechanism to the feed port of the second turret.

[0010] After the spring gripper disengages from the second sector-shaped cam block, the spring gripper automatically resets and clamps the semi-finished part.

[0011] The material handling device is connected to the second turret, and it transfers the assembled nozzle assembly from the second turret.

[0012] Furthermore, the outer edge of the tenth turntable is provided with several tenth turntable opening slots for carrying semi-finished materials, and the main body of the semi-finished materials is provided with a protruding ring that hangs at the tenth turntable opening slot.

[0013] The fourth gripper includes a second Y-shaped gripper body and a fourth spring. The middle part of the second Y-shaped gripper body is horizontally rotatably mounted on the tenth turntable. The front end of the second Y-shaped gripper body is provided with a long and a short fork. The end of the second long fork is provided with a fourth roller for cooperating with the second sector-shaped cam block. The rear end of the second Y-shaped gripper body is connected to the fourth spring. The other end of the fourth spring is mounted on the tenth turntable near the axis of the second Y-shaped gripper body.

[0014] When the tenth turntable rotates to the point where the fourth roller contacts the second sector-shaped cam block, the fourth gripper is in the open position.

[0015] Furthermore, when the tenth turntable rotates to the point where the fourth roller leaves the second sector-shaped cam block, the fourth spring pulls the second Y-shaped claw body to rotate and reset, and the second short fork rotates toward the opening slot of the tenth turntable to clamp the semi-finished material in the opening slot of the tenth turntable.

[0016] Furthermore, an auxiliary clamping arm is fixedly installed on the second long fork at a different height from the second short fork, with the end of the auxiliary clamping arm extending toward the end of the second short fork.

[0017] Furthermore, a third sector-shaped limiting plate that does not overlap with the second sector-shaped cam block is provided on the periphery of the tenth turntable. An opening is formed between the two ends of the third sector-shaped limiting plate and the second sector-shaped cam block, which serve as the discharge port of the first turret and the feed port of the second turret, respectively.

[0018] In the direction of rotation, each of the fourth grippers sequentially passes through the first turret outlet, the third sector-shaped limiting plate, the second turret inlet, and the second sector-shaped cam block.

[0019] Furthermore, the material handling device is provided with a Y-shaped guide plate, which is located at the end of the third sector-shaped limiting plate in the rotation direction, and a blowing device is provided at the end of the Y-shaped guide plate.

[0020] The material feeding system for the nozzle assembly of the dual turret processing production line provided by this invention has the following advantages:

[0021] (1) It can perform material conveying and transmission of semi-finished materials in real time without stopping the first and second turrets, which greatly improves production and processing efficiency.

[0022] (2) The fourth gripper on the turntable material transfer mechanism is a spring gripper. The opening and closing of the fourth gripper is controlled by the fan-shaped cam block set around the turntable material transfer mechanism, so as to grip or release the semi-finished material at the appropriate position. The turntable material transfer mechanism completes the transfer of the semi-finished material on the first turret to the second turret during the rotation process.

[0023] (3) The spring gripper and the sector-shaped cam block cooperate to achieve the opening / closing of specific positions. The pure mechanical cooperation has no electrical signal control, resulting in a low failure rate and easy maintenance.

[0024] (4) A fan-shaped limiting plate is also provided around the turntable material transfer mechanism to prevent semi-finished materials from falling off;

[0025] (5) The material handling device is equipped with a Y-shaped guide plate to transport the final assembled finished nozzle assembly to the discharge track. At the same time, in order to better separate the finished nozzle assembly from the second turret, a purging device is provided at the end of the Y-shaped guide plate to facilitate the nozzle assembly to fall off the second turret by purging high-pressure gas.

[0026] (6) The material conveying system can fully realize the integrated production line operation of feeding, transferring and discharging of the main plug, air bag and long pipe. The whole process does not require manual intervention, which greatly improves processing efficiency and saves labor costs. Attached Figure Description

[0053] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the invention. However, it will be apparent to those skilled in the art that the invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid obscuring the invention.

[0054] To fully understand this invention, detailed steps and structures will be presented in the following description to illustrate the technical solution of this invention. Preferred embodiments of the invention are described in detail below; however, in addition to these detailed descriptions, the invention may have other embodiments.

[0055] Reference Figure 6-7As shown, the present invention provides a dual-turret nozzle assembly device, which includes a first turret 1000, a turntable material transfer mechanism 3000, and a second turret 2000.

[0056] The first turret 1000 is used to insert the air bag 2 into the main plug 1 to form... Figure 4 The semi-finished material 4 is transferred by the turntable transfer mechanism 3000 to the second turntable 2000. The second turntable 2000 assembles the semi-finished material 4 with the long pipe 3 to form the nozzle assembly 5.

[0057] The structure of the first turret 1000, the turntable material transfer mechanism 3000, and the second turret 2000 will be further explained below:

[0058] First turret 1000

[0059] like Figure 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.

[0060] The specific structure of the first turret 1000 is explained below:

[0061] 1) Main body plug clamping and pressing mechanism 1010

[0062] 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.

[0063] 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.

[0064] The first pressing mechanism 1012 and the first clamping mechanism 1013 are respectively mounted on the first turntable 1002 and the second turntable 1003. The first pressing mechanism 1012 and the first clamping mechanism 1013 each include a plurality of first downward pressing push 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 accompanied by 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.) 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 12 Using an abbreviated drawing method, only one of the first downward push rod 1012-1 and the first upward push rod 1022-1 is shown. In the actual product, the first turret is provided with several first downward push rods 1012-1 and first upward push rods 1022-1 arranged in a circle.

[0065] like Figure 15 As shown, the first downward push rod 1012-1 is provided with a first guide rail bracket 1012-2, a first push rod 1012-3, and a first spring 1012-4. The first guide rail bracket 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 mounted on the first guide rail bracket 1012-2. The upper end of the first push rod 1012-3 is provided with a first roller that rolls with the cam groove 1011-1. The lower end face of the first push rod 1012-3 is pressed with the main body plug 1 or the semi-finished material 4. The bottom end of the first spring 1012-4 is connected to the first push rod 1012-3 and the top end of the first spring 1012-4 is connected to the first turntable 1002 or the fifth turntable 2002. The first spring 1012-4 provides an upward pulling force to the first push rod 1012-3 so that the first roller 1012-5 always rolls along the inner upper surface of the cam groove 1011-1.

[0066] 2) Airbag clamping and pushing mechanism 1020

[0067] The air bag clamping and pushing mechanism 1020 is provided with a second cam ring 1021, a first upper pushing mechanism 1022 and a second clamping mechanism 1023 in sequence from bottom to top.

[0068] The second cam ring 1021 is statically mounted on the first turret body 1001, and the upper end face of the second cam ring 1021 is provided with cam surfaces 1021-1 of varying heights along the circumferential direction.

[0069] The first lifting mechanism 1022 and the second clamping mechanism 1023 are respectively installed on the fourth turntable 1005 and the third turntable 1004. The first lifting mechanism 1022 and the second clamping mechanism 1023 respectively include a number of second grippers 1023-1 and a number of first lifting push rods 1022-1 circumferentially arranged on the fourth turntable 1005 and the third turntable 1004. The outer edge of the third turntable 1004 is provided with a ring of third turntable opening grooves 1004-1 for accommodating the air bag 2. The lower half of the air bag 2 is clamped by the second grippers 1023-1 located on the lower surface of the third turntable 1004. The first lifting push rods 1022-1 move up and down in cooperation with the second cam ring 1021 during the rotation of the first turret body 1001.

[0070] like Figure 16-17 As 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.

[0071] 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.

[0072] The second gripper 1023-1 is a spring gripper comprising a first Y-shaped gripper body 1023-2 and a third spring 1023-3. The middle part of the first Y-shaped gripper body 1023-2 is horizontally rotatably mounted on the lower surface of the third turntable 1004. The front end of the first Y-shaped gripper body 1023-2 is provided with a long and a short forked part. The end of the first long forked part 1023-5 is provided with a third roller 1023-4 for cooperating with the first sector-shaped cam block 1004-2. The rear end of the first Y-shaped gripper body 1023-2 is connected to the third spring 1023-3. The other end of the third spring 1023-3 is mounted on the inner side of the third turntable 1004. When the third turntable 1004 rotates to the point where the second gripper 1023-1 contacts the first sector-shaped cam block 1004-2, the second gripper 1023-1 opens. When the third turntable 1004 rotates to the point where the second gripper 1023-1 leaves the first sector-shaped cam block 1004-2, the second gripper 1023-1 closes to hold the air bag 2 in the opening slot 1004-1 of the third turntable. At this time, the air bag 2 is squeezed by the first short fork portion 1023-6 relative to the outer side of the opening slot 1004-1 of the third turntable, thus being clamped and fixed in the opening slot 1004-1. The first sector-shaped limiting plate 1004-3 acts as a circumferential limiting plate, preventing the air bag 2 from falling off during the rotation of the turret.

[0073] Within the mold closing position area of ​​the first turret 1000, the first cam ring 1011 is recessed downwards and the second cam ring 1021 is protruding upwards, causing the first downward push rod 1012-1 to float downwards and press against the upper end face of the main body plug 1 held by the first gripper 1013-1, and the first upward push rod 1022-1 to float upwards and push the air bag 2 held by the second gripper 1023-1 upwards and insert it into the main body plug 1 to form a semi-finished part 4.

[0074] like Figure 11 and Figure 12As shown, a ninth turntable 1006 is fixedly mounted on the first turret body 1001. An electromagnetic control mechanism 1030 is provided on the first turret body 1001 to control the opening and closing of each first gripper 1013-1. The electromagnetic control mechanism 1030 includes a sector magnet 1031 and several solenoid valves 1032 circumferentially arranged on the ninth turntable 1006. The sector magnet 1031 is statically mounted on the first turret body 1001. The solenoid valves 1032 on the first turret body 1001 correspond one-to-one with the first grippers 1013-1 in the axial direction and are electrically connected. When the solenoid valve 1032 rotates to the area of ​​the sector magnet 1031, the solenoid valve 1032 senses the magnetic field and closes the corresponding first gripper 1013-1. When the solenoid valve 1032 leaves the area of ​​the sector magnet 1031, the solenoid valve 1032 opens the corresponding first gripper 1013-1. It should be noted that the mold closing position area of ​​the first turret 1000 is located within the axial projection area of ​​the sector magnet 1031, so as to ensure that the first gripper 1013-1 is always in a closed state when the first turret 1000 is closed.

[0075] In addition, such as Figure 7 and Figure 9 As shown, the first turret 1000 is connected to a main body plug feeding device 1040 and an air bag conveying device 1050. The main body plug feeding device 1040 feeds the main body plug 1 into the second turntable opening slot 1003-1 in front of the sector magnet 1031. The air bag conveying device 1050 is connected to the starting position of the first cam block 1004-2. The air bag conveying device 1050 feeds the air bag 2 and transfers it to the rear side of the first cam block 1004-2 (e.g., ...). Figure 8 In the third turntable opening slot 1004-1 (as shown).

[0076] It should be noted that the front and back sides of this article are determined by the direction of the turret's rotation.

[0077] Second turret 2000

[0078] like Figure 20-23 As shown, the second turret 2000 is provided with a second turret body 2001, and the second turret body 2001 is provided with a fifth turntable 2002, a sixth turntable (not shown in the figure), a seventh turntable 2004, and an eighth turntable 2005 in sequence above and below.

[0079] The second turret body 2001 is equipped with a material clamping and pressing mechanism 2010 and a long tube clamping and lifting mechanism 2020 installed on its upper and lower sides. The material clamping and pressing mechanism 2010 and the long tube clamping and lifting mechanism 2020 are used to clamp the semi-finished material 4 and the long tube 3, respectively. The long tube clamping and lifting mechanism 2020 pushes the long tube 3 upward to insert it into the semi-finished material 4 to form the nozzle assembly 5. At the same time as the long tube clamping and lifting mechanism 2020 pushes upward, the material clamping and pressing mechanism 2010 presses down on the upper end face of the semi-finished material 4.

[0080] The material clamping and pressing mechanism 2010 is provided with a third cam ring 2011, a second pressing mechanism 2012 and a third clamping mechanism 2013 arranged sequentially from top to bottom. The third cam ring 2011 is statically mounted on the second turret body 2001. The second pressing mechanism 2012 and the third clamping mechanism 2013 are respectively mounted on the fifth turntable 2002 and the sixth turntable. The second pressing mechanism 2012 and the third clamping mechanism 2013 respectively include a number of second pressing push rods 2012-1 and a number of third grippers 2013-1 arranged circumferentially on the fifth turntable 2002 and the sixth turntable. The outer edge of the sixth turntable is provided with a sixth turntable opening groove for supporting the semi-finished material 4, and the lower half of the semi-finished material 4 is clamped by the third grippers 2013-1 located on the lower surface of the sixth turntable. The second pressing push rods 2012-1 move up and down in cooperation with the third cam ring 2011 during the rotation of the second turret body 2001.

[0081] The long tube clamping and lifting mechanism 2020 is arranged from bottom to top as follows: a fourth cam ring 2021, a second lifting mechanism 2022, and a fourth clamping mechanism 2023. The fourth cam ring 2021 is statically mounted on the second turret body 2001. The second lifting mechanism 2022 is mounted on the eighth turntable 2005. The second lifting mechanism 2022 includes several second lifting push rods 2022-1 circumferentially arranged on the eighth turntable 2005. The second lifting push rods 2022-1 move up and down in coordination with the fourth cam ring 2021 as the second turret body 2001 rotates. The fourth clamping mechanism 2023 includes a ring of seventh turntable opening slots 2004-1 on the outer edge of the seventh turntable 2004 to support the long tube 3, and second sector-shaped limiting plates 2023-1 statically spaced on the outer edge of the seventh turntable to prevent the long tube 3 from falling out of the seventh turntable opening slots 2004-1.

[0082] In this invention, the material clamping and pressing mechanism 2010 on the second turret 2000 is structurally similar to the main body plug clamping and pressing mechanism 1010 on the first turret 1000. The difference is that the main body plug clamping and pressing mechanism 1010 is used to clamp and press down the main body plug 1, while the material clamping and pressing mechanism 2010 is used to clamp and press down the semi-finished material 4. However, the top of the semi-finished material 4 is still the main body plug 1, so the main body plug clamping and pressing mechanism 1010 of the first turret 1000 can be directly applied to the material clamping and pressing mechanism 2010 of the second turret 2000. The structural description of the material clamping and pressing mechanism 2010 will not be elaborated here.

[0083] Similarly, the structure of the long tube clamping and pushing mechanism 2020 on the second turret 2000 is basically the same as that of the air bag clamping and pushing mechanism 1020 on the first turret 1000, so the structural description of the long tube clamping and pushing mechanism 2020 will not be repeated.

[0084] Similarly, the second turret 2000 also carries the same ninth turntable 1006 and electromagnetic control mechanism 1030 as the first turret 1000, with identical structure and function. The opening and closing of the third gripper 2013-1 is controlled by the solenoid valve 1032 on the second turret 2000 sweeping across the sector magnet 1031, thereby gripping or releasing the semi-finished part 4. The mold-closing position of the second turret 2000 is always located within the axial projection area of ​​the sector magnet 1031, ensuring that the third gripper 2013-1 is always closed when the second turret 2000 is closed. 1) When the solenoid valve 1032 rotates to the area of ​​the sector magnet 1031, the solenoid valve 1032 senses the magnetic field and closes the corresponding third gripper 2013-1. When the solenoid valve 1032 leaves the area of ​​the sector magnet 1031, the solenoid valve 1032 opens the corresponding third gripper 2013-1.

[0085] The mold closing principle of the second turret 2000 is 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 recessed downward and the fourth cam ring 2021 is raised upward, so that the second downward push rod 2012-1 floats downward and presses against the upper end face of the semi-finished material 4 held by the third claw 2013-1. At the same time, the second upward push rod 2022-1 floats upward and pushes the long tube 3 in the opening slot 2004-1 of the seventh turntable upward and inserts it into the semi-finished material 4 to form the nozzle assembly 5.

[0086] In addition, such as Figure 7 and Figure 9 As shown, the second turret 2000 is also connected to a long pipe conveying device 2040 and a material taking device 2050. The long pipe conveying device 2040 sends the long pipe 3 to the opening slot 2004-1 of the seventh turntable, and the material taking device 2050 takes away the nozzle assembly 5 assembled on the second turret 2000.

[0087] like Figure 23 As shown, the material handling device 2050 is equipped with a Y-shaped guide plate 2051. A purging device is provided at the end of the Y-shaped guide plate 2051. The gas sprayed by the purging device causes the nozzle assembly 5 on the turntable to shake. During the rotation of the second turret, it cooperates with the Y-shaped guide plate 2051. The nozzle assembly 5 is transported to the discharge track 2052 through the Y-shaped guide plate 2051 to complete the discharge.

[0088] 3000 rotary material transfer mechanism

[0089] like Figure 10As shown, the turntable material transfer mechanism 3000 is provided with a tenth turntable 3001. The outer edge of the tenth turntable 3001 is provided with several tenth turntable opening slots. Several fourth grippers 3004 are installed on the tenth turntable 3001. The rotation direction of the tenth turntable 3001 is opposite to that of the first turret 1000 and the second turret 2000 on both sides.

[0090] A second sector-shaped cam block 3002 and a third sector-shaped limiting plate 3003 are stationary on the periphery of the tenth turntable 3001. A turntable material transfer mechanism inlet and a turntable material transfer mechanism outlet are provided between the two ends of the second sector-shaped cam block 3002 and the third sector-shaped limiting plate 3003. The turntable material transfer mechanism inlet is connected to the first turret outlet, and the turntable material transfer mechanism outlet is connected to the second turret 2000.

[0091] The outer edge of the tenth turntable 3001 is provided with several tenth turntable opening slots, such as Figure 24 As shown, the fourth gripper 3004 is a spring gripper comprising a second Y-shaped gripper body 3004-1 and a fourth spring 3004-6. The second Y-shaped gripper body 3004-1 is horizontally rotatably mounted on the tenth turntable 3001 at its middle part. The front end of the second Y-shaped gripper body 3004-1 has a long and a short forked portion. The second long forked portion 3004-2 and the second short forked portion 3004-3 are at the same height. The end of the second long forked portion 3004-2 is provided with a fourth roller 3004-4 for cooperating with the second sector-shaped cam block 3002. An auxiliary gripping arm 3004-5 located at a different height from the second short forked portion 3004-3 is fixedly mounted on the second long forked portion 3004-2. The other end of the auxiliary gripping arm 3004-5 extends toward the second short forked portion 3004-3. The rear end of the second Y-shaped claw body 3004-1 is connected to the fourth spring 3004-6, and the other end of the fourth spring 3004-6 is installed on the tenth turntable 3001 near the axis of the second Y-shaped claw body 3004-1.

[0092] like Figure 25 As shown, the second short forked portion 3004-3 has a first clamping notch 3004-31 on the other side relative to the second long forked portion 3004-2, and the end of the auxiliary clamping arm 3004-5 has a second clamping notch 3004-51 on the same side as the first clamping notch 3004-31. In the rotation direction, both the first clamping notch 3004-31 and the second clamping notch 3004-51 are located on the front side of the second Y-shaped claw body 3004-1. By simultaneously pressing the main body plug 1 at different heights through the second short forked portion 3004-3 and the auxiliary clamping arm 3004-5, the clamping effect becomes more stable.

[0093] When the tenth turntable 3001 rotates to the point where the fourth roller 3004-4 contacts the second sector-shaped cam block 3002, the fourth gripper 3004 is in the open state. When the tenth turntable 3001 rotates to the point where the fourth roller 3004-4 leaves the second sector-shaped cam block 3002, the fourth spring 3004-6 pulls the second Y-shaped claw body 3004-1 to rotate and reset. The short fork 3004-3 rotates toward the opening slot of the tenth turntable to clamp the semi-finished material 4 in the opening slot of the tenth turntable. At this time, the main body plug 1 of the semi-finished material 4 is simultaneously squeezed by the second short fork 3004-3 and the auxiliary clamping arm 3004-5 relative to the outside of the opening slot of the tenth turntable to be clamped and fixed at the opening slot of the tenth turntable.

[0094] The structure and working principle of the fourth gripper 3004 are basically the same as those of the second gripper 1023-1 on the first turret. For details, please refer to the relevant description of the second gripper 1023-1 above.

[0095] In the direction of rotation, the fourth gripper 3004 sequentially passes through the first turret outlet, the third sector-shaped limiting plate 3003, the second turret inlet, and the second sector-shaped cam block 3002.

[0096] The working process of this invention is briefly described as follows:

[0097] 1) The main body plug 1 and the air bag 2 are respectively conveyed to the first turret 1000 and clamped by the first gripper 1013-1 and the second gripper 1023-1 respectively. Taking the conveying of the air bag 2 as an example: The air bag conveying device 1050 sends the air bag 2 to the feed port of the first turret (the feed port of the first turret is located behind the end point of the first sector cam block 1004-2). When the second gripper 1023-1 engages with the first sector cam block 1004-2, the second gripper 1023-1 is in the open state. As the turret rotates, the second gripper 1023-1 disengages from the first sector cam block 1004-2. Under the action of the third spring 1023-3, the second gripper 1023-1 resets and clamps the air bag 2 in the opening slot 1004-1 of the third turret.

[0098] When the first turret 1000 rotates to the mold closing position, the first downward push rod 1012-1 floats downward and presses against the upper end face of the main body plug 1, and at the same time the first upward push rod 1022-1 floats upward to push the air bag 2 upward and insert it into the main body plug 1 to form the semi-finished part 4.

[0099] 2) The semi-finished material 4 on the first turret 1000 is removed by the turntable transfer mechanism 3000 and transferred to the second turret 2000. On the second turret 2000, the semi-finished material 4 is held by the third gripper 2013-1, and the long pipe 3 is fed into the seventh turntable opening slot 2004-1 of the second turret 2000 by the long pipe conveying device 2040.

[0100] 3) When the second turret 2000 rotates to the mold closing position, the second downward push rod 2012-1 floats downward and presses against the upper end face of the semi-finished material 4, and at the same time the second upward push rod 2022-1 floats upward to push the long tube 3 upward and insert it into the semi-finished material 4 to form the nozzle assembly 5.

[0101] 4) As the second turret 2000 continues to rotate, when the nozzle assembly 5 rotates to the position of the material taking device 2050, the Y-shaped guide plate 2051 of the material taking device 2050 continuously blows gas, causing the nozzle assembly 5 to detach from the turret and flow to the discharge track 2052 under the action of the Y-shaped guide plate 2051 to finally complete the discharge.

[0102] 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 gripper 1013-1 or third gripper 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 gripper 1013-1, and the turntable material transfer mechanism 3000 transfers the semi-finished material 4 from the first turret 1000; 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 gripper 2013-1, so that the material handling device 2050 can remove the assembled nozzle assembly 5 from the second turret 2000.
