[0025] Please refer to Figure 1-5 A gas generator tube feeding mechanism comprises a first mounting frame 1, a feeding box 2 is fixed at one end of the top of the first mounting frame 1, a feeding adjustment mechanism is arranged inside the feeding box 2 to adapt to the feeding of tubes of different lengths, a primary conveying mechanism is arranged at one end of the feeding box 2, a second mounting frame 13 is fixed at the end of the top of the first mounting frame 1 away from the feeding box 2, a secondary conveying mechanism is arranged inside the end of the second mounting frame 13 close to the feeding box 2, a third mounting frame 18 is fixed at the top of the second mounting frame 13, a positioning mechanism is arranged at the top of the third mounting frame 18, and when in use Through the setting of the feeding adjustment mechanism, it can adapt to the feeding of gas generator tubes of different lengths, which greatly improves the adaptability during use, and has a simple structure, convenient operation and high practicality; through the setting of the primary conveying mechanism and the secondary conveying mechanism, the tubes are fed in an orderly manner, and one is fed each time. At the same time, with the setting of the positioning mechanism, the tube is accurately positioned at the position to be taken, which has a certain error prevention function, prevents the occurrence of wrong feeding or insufficient feeding, improves the accuracy of feeding, and replaces manual labor with a simple mechanical mechanism to improve feeding efficiency.

[0026] Please refer to Figure 2 The feeding adjustment mechanism includes a baffle plate 4, which is slidably connected to the inner side of the feeding box 2. A plurality of guide rods 5 are fixed to one side of the baffle plate 4. One end of the plurality of guide rods 5 away from the baffle plate 4 passes through the feeding box 2 and is fixed with a first connecting plate 6. The inner side of the first connecting plate 6 is rotatably connected with a threaded rod 8, and the threaded rod 8 is threadedly connected to the feeding box 2. Specifically, when it is necessary to adjust the distance between the baffle plate 4 and the inner wall of the feeding box 2, the staff can rotate the adjusting disk 7 to drive the threaded rod 8 to rotate. When the threaded rod 8 rotates, it will drive the first connecting plate 6 to perform displacement movement, and then drive the baffle plate 4 to perform displacement movement through the guide rod 5, thereby adjusting the distance between the baffle plate 4 and the inner wall of the feeding box 2, so as to adapt to the feeding of tubes of different lengths, thereby improving adaptability.

[0027] Please refer to Figure 3, a first-level slide 9 is fixed on the top of the feeding box 2 near the end of the second mounting frame 13, and the first-level conveying mechanism includes a first cylinder 10 fixed on the end of the feeding box 2 near the first-level slide 9 and located below the first-level slide 9, a second connecting plate 11 is fixed on the output end of the first cylinder 10, and a first-level top plate 12 is fixed on the top end of the second connecting plate 11, and the first-level top plate 12 is slidably connected to the end of the inner side of the feeding box 2 near the first-level slide 9, and the top of the first-level slide 9 is set as an inclined table surface. Before feeding, the pipe body is stacked between the guide rod 5 and the inner wall of the feeding box 2. Each time feeding is performed, the first cylinder 10 is started to drive the first-level top plate 12 to move downward, so that it moves to the bottom of the inner side of the feeding box 2, and then the first cylinder 10 is started again to drive the first-level top plate 12 to move upward, thereby transporting the pipe body located on its top upward, and when the pipe body is transported to the top of the first-level slide 9, it will roll down along the first-level slide 9, thereby completing the first-level feeding work;

[0028] It should be noted that the thickness of the primary top plate 12 should be smaller than the sum of the diameters of the two pipe bodies, so as to ensure that the primary top plate 12 can only transport one pipe body each time.

[0029] Please refer to Figure 4-5 The secondary conveying mechanism includes a secondary slide 14 fixed to the inner side of the second mounting frame 13 and located above the end of the primary slide 9 away from the feed box 2. The top of the secondary slide 14 is an inclined table surface. The end of the secondary slide 14 away from the primary slide 9 is provided with a stop bar 27. A positioning baffle 28 is fixed on the secondary slide 14 and at one end of the stop bar 27. A first guide plate 15 is fixed to the bottom of the secondary slide 14 near the end of the primary slide 9. A second guide plate 16 is fixed to the bottom of the primary slide 9 near the end of the secondary slide 14. A second cylinder 25 is fixed to the bottom of the second mounting frame 13. A secondary top plate 17 is fixed to the output end of the second cylinder 25. The secondary top plate 17 is slidably connected between the first guide plate 15 and the second guide plate 16. The secondary top plate 1 7 is located between the secondary slide 14 and the primary slide 9, and the top of the secondary slide 14 is arranged above the primary slide 9. Specifically, during feeding, the tubes transported by the primary conveying mechanism will be arranged in a row on the inclined table surface at the top of the primary slide 9. When the secondary conveying mechanism is working, the second cylinder 25 starts to drive the secondary top plate 17 to move downward, so that the tubes on the top of the primary slide 9 roll to the top of the secondary top plate 17, and then the second cylinder 25 drives the secondary top plate 17 to move upward. When the tubes are transported to the top of the secondary slide 14, the tubes will roll down along the secondary slide 14 and be blocked by the blocking bar 27 to wait for material removal. Through the setting of the secondary conveying mechanism, one tube is transported each time, ensuring orderly feeding, and improving the accuracy and efficiency of feeding.

[0030] It should be noted that in actual use, in order to facilitate the transportation of the tube body, the top of the primary top plate 12 and the secondary top plate 17 can be set as an inclined table top, and the inclination direction thereof is respectively the same as the inclination direction of the primary slide 9 and the secondary slide 14, so as to facilitate smoother rolling of the tube body and avoid the situation where the tube body stays on the top of the secondary top plate 17 or the primary top plate 12 and is transported empty.

[0031] Please refer to Figure 3-5 A material taking notch 26 is provided on the inner side of the secondary slide 14 near the positioning baffle 28 , and the material taking notch 26 is provided to facilitate the robot arm to grab the tube body.

[0032] Please refer to Figure 5 The positioning mechanism includes a positioning cylinder 20 fixed on the top of the third mounting frame 18, a first guide rail 19 and a second guide rail 22 are respectively fixed on the top of the third mounting frame 18 and located at both ends of the positioning cylinder 20, a first guide connecting plate 21 is slidably connected to the top of the first guide rail 19, and a second guide connecting plate 23 is slidably connected to the top of the second guide rail 22, the first guide connecting plate 21 and the second guide connecting plate 23 are both fixedly connected to the output end of the positioning cylinder 20, and a positioning plate 24 is fixed at the bottom of the second guide connecting plate 23 away from the end of the positioning cylinder 20, and the positioning The positioning plate 24 is located above the end of the secondary slide 14. Specifically, the position of the tube body may shift when it rolls on the top of the secondary slide 14. At this time, directly using a robot to pick up the material may result in insufficient loading accuracy and the appearance of defective products. Therefore, in this embodiment, after the secondary conveying mechanism conveys the tube body to the top of the secondary slide 14 close to the end of the positioning baffle 28, the positioning cylinder 20 is started, driving the second guide connecting plate 23 and the positioning plate 24 to approach the tube body, and push the tube body to a position close to the positioning baffle 28 to position it.

[0033] It should be noted that since the force point of the second guide connecting plate 23 is on the side and the force is relatively large during positioning, if the first guide rail 19 and the first guide connecting plate 21 are not added, the second guide connecting plate 23 will easily get stuck during movement. Therefore, the setting of the first guide connecting plate 21 makes the movement of the second guide connecting plate 23 smoother and more stable, thereby improving the service life of the positioning mechanism.

[0034] The use process of a gas generator tube feeding mechanism provided by the utility model is as follows:

[0035] When using the generator tube feeding mechanism, firstly, a number of generator tube parts to be loaded are stacked between the feeding box 2 and the guide rod 5. When feeding is required, the first cylinder 10 is started to drive the second connecting plate 11 and the first top plate 12 to descend to the bottom of the inner side of the feeding box 2, so that the generator tube moves to the top of the first top plate 12 under its own weight. Then, the first cylinder 10 is started to drive the first top plate 12 to move upward, and the generator tube located at the top thereof is transported to the top of the first slide 9, and rolls along the first slide 9 to the vicinity of the second top plate 17 and is arranged in this way. Then, the second cylinder 25 is started to drive the second top plate 17 to move downward, so that the tube located at the top of the first slide 9 rolls to the top of the second top plate 17. Then, the second cylinder 25 is started to drive the second top plate 17 to move upward, and the tube located at the top of the second top plate 17 is transported to the top of the second slide 14 and rolls along the second slide 14 to the vicinity of the baffle 27.

[0036] Then the positioning cylinder 20 starts to drive the second guide connecting plate 23 to move toward the direction close to the tube body, so that the second guide connecting plate 23 drives the positioning plate 24 to move, and the positioning plate 24 pushes the tube body to abut against the positioning baffle 28 to position it;

[0037] When it is necessary to adjust the distance between the baffle plate 4 and the inner wall of the feed box 2, the staff can drive the threaded rod 8 to rotate by turning the adjustment disk 7. When the threaded rod 8 rotates, it will drive the first connecting plate 6 to move, and then drive the baffle plate 4 to move through the guide rod 5, thereby adjusting the distance between the baffle plate 4 and the inner wall of the feed box 2.

[0038] The top of the feed box 2 is slidably connected with a cover body 3, which is made of a transparent material.
