DETAILED DESCRIPTION

[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] like Figures 1-13 The powder packaging conveyor on the ammonium perchlorate production line is shown.

[0034] Example 1: Figures 1-13 As shown, the technical solution adopted by the present invention is as follows: the powder packaging conveyor on the ammonium perchlorate production line includes a first conveyor belt 1, a discharge pipe 14 and a third limiting rod 41.

[0035] The first conveyor belt 1 is installed between two side panels. The two side panels are respectively a first side panel 3 and a second side panel 51. The inner sides of the first side panel 3 and the second side panel 51 are both installed with a limiting block 2 for limiting the packaging bag 13.

[0036] A material barrel 5 is provided above the first conveyor belt 1, and a discharge pipe 14 is mounted at the lower end of the material barrel 5. The lower end of the discharge pipe 14 moves up and down relative to the first conveyor belt 1, thereby allowing the discharge pipe 14 to be inserted into or removed from the packaging bag 13 on the first conveyor belt 1. The material in the material barrel 5 enters the packaging bag 13 through the discharge pipe 14.

[0037] In this embodiment, if Figure 8 As shown, a second electric push rod 44 is mounted on the first side plate 3 , the telescopic end of the second electric push rod 44 is vertically upward, and the telescopic end of the second electric push rod 44 is fixedly connected to the first connecting plate 6 . The material barrel 5 is mounted on the first connecting plate 6 .

[0038] like Figure 2 As shown, two first clamping units are symmetrically provided on the discharge tube 14 , and the first clamping units are used to clamp the packaging bags 13 on both sides of the discharge tube 14 so that the discharge tube 14 is wrapped by the packaging bags 13 .

[0039] Each first clamping unit includes two symmetrically arranged first limiting rods 16. A second fixing block 24 is fixedly mounted on the outer wall of the feed tube 14. A second guide block 19 is fixedly mounted on the second fixing block 24 and slides with the first limiting rod 16. The second guide block 19 is L-shaped and defines a second guide groove 20. A rectangular block 26 is fixedly connected to the first limiting rod 16 and slides within the second guide groove 20. The two second guide blocks 19 within the same clamping unit are symmetrically arranged. A drive member is mounted on the feed tube 14 to drive the first limiting rod 16 along the second guide block 19.

[0040] The first limiting rod 16 moves downward along the vertical portion of the second guide block 19, and then moves along the horizontal portion of the second guide block 19 toward the packaging bag 13. The two first limiting rods 16 clamp the packaging bag 13, wrapping the discharge tube 14 with the packaging bag 13. The two first clamping units clamp the packaging bag 13 on both sides of the discharge tube 14, thereby wrapping the packaging bag 13 around the discharge tube 14 and preventing droplets of material in the packaging bag 13 from escaping upward through the gap between the packaging bag 13 and the discharge tube 14.

[0041] In order to make the packaging bag 13 fit more tightly on the discharge tube 14 and avoid a gap between the packaging bag 13 and the discharge tube 14, a first limiting rod 16 is provided with an arc surface. A protrusion 50 adapted to the arc surface of the first limiting rod 16 is fixed on the outer wall of the discharge tube 14. Figure 13 As shown, after the two first limiting rods 16 clamp the packaging bag 13 , the arcuate surfaces of the first limiting rods 16 fit onto the protrusion 50 .

[0042] The driving member includes a first guide block 17. A first fixed block 23 is fixedly installed on the outer wall of the discharge tube 14, and one end of the first guide block 17 is fixedly connected to the first rotating rod, and the first rotating rod is rotatably installed on the first fixed block 23. A first guide groove 18 is provided at the other end of the first guide block 17, and a cylindrical block 27 is connected to the rectangular block 26, and the cylindrical block 27 is movably arranged in the first guide groove 18. The ends of the two first guide blocks 17 that are close to each other are fixedly connected to the first gear 21, and the first gear 21 is coaxially arranged with the corresponding first rotating rod. The two first gears 21 are meshed. A first motor 22 is installed on the first fixed block 23, and the output shaft of the first motor 22 is fixedly connected to one of the first rotating rods.

[0043] The first motor 22 drives the corresponding first rotating rod to rotate, causing the corresponding first guide block 17 to rotate. Under the action of the two first gears 21, the two first guide blocks 17 rotate simultaneously and in opposite directions. The first guide blocks 17 rotate around the first rotating rod, causing the rectangular block 26 to slide along the second guide groove 20 and the cylindrical block 27 to move along the first guide groove 18.

[0044] like Figure 8 As shown, the first side plate 3 has a first sliding hole formed therein, into which the first sliding seat 28 is mounted for vertical sliding movement. A fifth motor 45 is mounted on the first side plate 3. The output shaft of the fifth motor 45 is fixedly connected to a third threaded rod 46, which is rotatably connected to the first side plate 3. The first sliding seat 28 is threadedly connected to the third threaded rod 46. The fifth motor 45 drives the third threaded rod 46 to rotate, which in turn drives the first sliding seat 28, causing it to move up and down along the first sliding hole.

[0045] like Figure 7 As shown, the first connecting seat 4 is provided with an upper limit sliding arrangement on the first sliding seat 28. The first connecting seat 4 is provided with a limit groove that slides with the first sliding seat 28. The first sliding seat 28 is provided with a second drive assembly that drives the first connecting seat 4 to slide. The second drive assembly includes a second threaded rod 40 and a fourth motor 39. The second threaded rod 40 is rotatably mounted on the first sliding seat 28. The fourth motor 39 is fixedly mounted on the first sliding seat 28, and the output shaft of the first sliding seat 28 is fixedly connected to the second threaded rod 40. The first connecting seat 4 is threadedly connected to the second threaded rod 40. The fourth motor 39 drives the second threaded rod 40 to rotate, thereby causing the first connecting seat 4 to move along the first sliding seat 28.

[0046] like Figure 5As shown, both ends of the first connecting seat 4 are fixedly connected to a second connecting seat 29. A second sliding seat 30 and a connecting block 31 are slidably mounted on each second connecting seat 29. The connecting block 31 is located on the side of the second sliding seat 30 near the end of the first connecting seat 4. A spring 34 is fixedly connected between the second sliding seat 30 and the connecting block 31.

[0047] A first drive assembly is mounted on the second connecting base 29 to drive the second sliding base 30. The first drive assembly includes a second motor 33 and a first threaded rod 32. The second motor 33 is fixedly mounted on the second connecting base 29, while the first threaded rod 32 is rotatably mounted on the second connecting base 29. The output shaft of the second motor 33 is fixedly connected to the first threaded rod 32.

[0048] Each connecting block 31 is fixedly connected to a second connecting plate 38. Each second connecting plate 38 is fixedly connected to a third limiting rod 41.

[0049] The second motor 33 drives the first threaded rod 32 to rotate, causing the two second sliding seats 30 to move away from each other. The second sliding seats 30, through the spring 34, push the connecting block 31 to move, causing the two connecting blocks 31 to move away from each other, thereby moving the two third limiting rods 41 away from each other. The two third limiting rods 41 tighten the opening of the packaging bag 13, bringing the two sides of the opening of the packaging bag 13 closer together, so that both sides of the opening of the packaging bag 13 contact the discharge tube 14. The first clamping unit then clamps the packaging bag 13 on both sides of the discharge tube 14, wrapping the packaging bag 13 around the discharge tube 14.

[0050] When the first clamping unit clamps the packaging bag 13 , the packaging bag 13 pulls the feeding tube 14 , causing the connecting block 31 to further compress the spring 34 and move closer to the second sliding seat 30 .

[0051] Each second connecting plate 38 is provided with a second clamping unit. The second clamping unit comprises two symmetrically arranged second limiting rods 36. One end of each second limiting rod 36 is rotatably mounted on the second connecting plate 38 via a second rotating rod. A second gear 37 is fixedly mounted on one end of each second limiting rod 36. The second gear 37 is coaxially arranged with the corresponding second rotating rod, and the two second gears 37 mesh with each other. A third motor 35 is provided on the second connecting plate 38, and the output shaft of the third motor 35 is drivingly connected to one of the second limiting rods 36.

[0052] After the first clamping unit clamps the packaging bags 13 on both sides of the discharge tube 14, the third motor 35 is activated, which drives the corresponding second limiting rods 36 to rotate. Under the action of the second gear 37, the two second limiting rods 36 rotate simultaneously. The two second limiting rods 36 clamp the packaging bag 13 on the side of the third limiting rod 41 close to the discharge tube 14, so that the packaging bag 13 is wrapped around the third limiting rod 41. The two sides of the packaging bag 13 between the third limiting rod 41 and the discharge tube 14 are abutted against each other, thereby sealing the bag 13.

[0053] like Figure 6 As shown, the second sliding seat 30 is provided with a first contact 42 and a second contact 43. The first contact 42 is connected to the control circuit of the first motor 22, and the second contact 43 is connected to the control circuit of the third motor 35. When the third limiting rod 41 tightens the opening of the packaging bag 13, as the second sliding seat 30 moves further, the third limiting rod 41 cannot move further, causing the connecting block 31 to overcome the elastic force of the spring 34 and move closer to the second sliding seat 30. This causes the connecting block 31 to squeeze the first contact 42, and then the first motor 22 is activated, causing the first clamping unit to clamp the packaging bag 13 on both sides of the discharge tube 14. When the first clamping unit clamps the packaging bag 13, it causes the connecting block 31 to move closer to the second sliding seat 30, squeezing the second contact 43. This activates the third motor 35, causing the second clamping unit to clamp the packaging bag 13 on the side of the third limiting rod 41.

[0054] The feed tube 14 is equipped with an exhaust assembly. This assembly includes an exhaust pipe 15, which is mounted on the feed tube 14. An exhaust passage is defined within the sidewall of the feed tube 14, the upper end of which communicates with the exhaust pipe 15. An exhaust port 25 is defined on the outer wall of the feed tube 14 and communicates with the lower end of the exhaust pipe 15.

[0055] Working principle: Initially, the rectangular block 26 is at the upper end of the vertical portion of the second guide block 19, the two first limiting rods 16 are away from each other, and the second limiting rod 36 is vertically upward and above the second gear 37.

[0056] When in use, the packaging bag 13 is placed just below the upper and lower feeding pipes 14 of the first conveyor belt 1, and the packaging bag 13 is between the two limiting blocks 2. The feeding pipe 14 and the third limiting rod 41 are both extended into the packaging bag 13.

[0057] The second motor 33 is then activated, rotating the first threaded rod 32. This in turn drives the second sliding seat 30 outward, causing the two second sliding seats 30 to move away from each other. The second sliding seat 30, via the spring 34, drives the connecting block 31 to move. The connecting block 31 drives the second connecting plate 38 to move, which in turn drives the third limiting rod 41 to move. The two third limiting rods 41 move away from each other, gradually tightening the opening of the packaging bag 13. The two sides of the opening of the packaging bag 13 gradually approach each other, bringing both sides of the upper end of the packaging bag 13 into contact with the discharge tube 14.

[0058] After the third limiting rod 41 tightens the opening of the packaging bag 13, as the second sliding seat 30 continues to move outward, the third limiting rod 41 cannot continue to move outward, causing the spring 34 to be further compressed, and the second sliding seat 30 approaches the connecting block 31 until the connecting block 31 squeezes the first contact 42. The first motor 22 is started, and the second motor 33 is turned off. The first motor 22 drives the first guide block 17 to rotate, and the two first guide blocks 17 rotate simultaneously. The first guide block 17 drives the first limiting rod 16 to move along the second guide groove 20 through the cylindrical block 27. The first limiting rod 16 moves downward along the vertical portion of the second guide block 19, so that the first limiting rod 16 moves to one side of the packaging bag 13, and then the first limiting rod 16 moves along the horizontal portion of the second guide block 19 close to the packaging bag 13. Until the two first limit rods 16 clamp the packaging bag 13, the packaging bags 13 on both sides of the discharge tube 14 are clamped, and the packaging bag 13 is wrapped on the discharge tube 14, preventing the droplets in the packaging bag 13 from escaping through the gap between the packaging bag 13 and the discharge tube 14, and can automatically adapt to the size of the packaging bag 13.

[0059] As the two first limiting rods 16 clamp the packaging bag 13, the packaging bag 13 pulls the third limiting rod 41 inward, causing the connecting block 31 to further compress the spring 34 and move closer to the second sliding seat 30, causing the connecting block 31 to press against the second contact point 43. This activates the third motor 35, rotating the second limiting rod 36 until the two second limiting rods 36 clamp the third limiting rod 41 near the packaging bag 13 on the side of the discharge tube 14, causing the packaging bag 13 to wrap around the third limiting rod 41. The two sides of the packaging bag 13 between the third limiting rod 41 and the discharge tube 14 are in contact, sealing the opening of the packaging bag 13 and effectively preventing the escape of the material in the packaging bag 13.

[0060] The material is then poured into the packaging bag 13 through the discharge pipe 14. During the pouring process, the fourth motor 39 is started, the second threaded rod 40 rotates, and the first connecting seat 4 moves along the first sliding seat 28. By controlling the forward and reverse rotation of the fourth motor 39, the first connecting seat 4 is moved back and forth along the first sliding seat 28, and the first connecting seat 4 drives the packaging bag 13 to move back and forth through the third limiting rod 41. In the process of the packaging bag 13 moving back and forth, the packaging bag 13 slides relative to the discharge pipe 14 and the first limiting rod 16, so that the bag opening of the packaging bag 13 remains sealed, preventing the material droplets stirred up in the packaging bag 13 from escaping upward. The sliding of the packaging bag 13 relative to the discharge pipe 14 is conducive to the uniform falling of the material into the packaging bag 13. And as the packaging bag 13 moves, the material in the packaging bag 13 shakes, further improving the uniformity of the material filling.

[0061] It should be noted that when a certain amount of material is poured into the packaging bag 13, the lower end of the packaging bag 13 becomes difficult to move. Afterwards, the first connecting seat 4 drives the upper part of the packaging bag 13 to move through the third limiting rod 41, so that the material falls evenly into the packaging bag 13.

[0062] During the filling process, the air extraction port 25 at the lower end of the discharge tube 14 is located inside the packaging bag 13. Since the bag opening inside the packaging bag 13 is sealed, the air inside the packaging bag 13 can be discharged through the air extraction port 25, the exhaust channel, and the air extraction pipe 15, so that the material can smoothly enter the packaging bag 13. It should be noted that the air extraction pipe 15 can be connected to an external collection mechanism to collect the material droplets discharged through the air extraction pipe 15. Of course, the air inside the packaging bag 13 can also be sucked by the first conveyor belt 1 through an air pump to prevent the air inside the packaging bag 13 from opening the bag opening. The collection mechanism and the air pump are both existing technologies and will not be described here.

[0063] After filling is complete, the second electric push rod 44 moves the material barrel 5 upward, which in turn moves the discharge tube 14 upward, withdrawing the discharge tube 14 from the packaging bag 13. As the discharge tube 14 is withdrawn from the packaging bag 13, the spring 34 pushes the connecting block 31 outward, causing the third limiting rod 41 to move outward, thereby maintaining tension on the upper end of the packaging bag 13 and maintaining the bag opening in a sealed state. The outward movement of the connecting block 31 releases its pressure on the first contact 42 and the second contact 43. Subsequently, the first motor 22 and the third motor 35 are activated, causing the first and second limiting rods 16 and 36 to return to their original positions, releasing their grip on the packaging bag 13.

[0064] The fifth motor 45 is started to move the first sliding seat 28 upward, the first connecting seat 4 upward, and the third limiting rod 41 upward, so that the third limiting rod 41 is drawn out of the packaging bag 13 .

[0065] Example 2: This example is an improvement based on Example 1.

[0066] An auxiliary transport assembly is installed above the first conveyor belt 1. The auxiliary transport assembly includes a second clamping plate 47 and a first clamping plate 12. Second sliding holes are formed in both the first side plate 3 and the second side plate 51. Slide blocks 9 are slidably mounted within the second sliding holes. A motorized slide rail 8 is also installed within the second sliding holes to drive the movement of the slide blocks 9.

[0067] The slider 9 is mounted with a first electric push rod 10. A connecting frame 11 is mounted on the telescopic end of the first electric push rod 10. The connecting frame 11 is connected to the second clamping plate 47. A second conveyor belt 48 is mounted on the second clamping plate 47. A support block 7 is fixedly connected between the first side plate 3 and the second side plate 51. Two first clamping plates 12 are mounted on the support block 7. A third conveyor belt 49 is mounted on the side of each first clamping plate 12 that is adjacent to each other.

[0068] After the third limiting rod 41 is drawn out of the packaging bag 13 , the first electric push rod 10 is activated to move the second clamping plates 47 closer to the packaging bag 13 until the two second clamping plates 47 clamp the upper end of the packaging bag 13 .

[0069] Afterwards, the first conveyor belt 1 and the electric slide rail 8 are started. Figure 10 In the direction shown, first conveyor belt 1 drives the lower end of packaging bag 13 to the left, electric slide 8 drives slider 9 to move leftward, slider 9 drives second clamping plate 47 to move leftward, and second clamping plate 47 drives the upper end of packaging bag 13 to move leftward, so that packaging bag 13 moves stably to the left. The movement speed of first conveyor belt 1 and slider 9 are coordinated to ensure that packaging bag 13 remains stable.

[0070] Until the left end of the second conveyor belt 48 approaches the right end of the third conveyor belt 49, the electric slide rail 8 is closed and the second and third conveyor belts 48, 49 are started. The lower end of the packaging bag 13 moves with the first conveyor belt 1, and the two second conveyor belts 48 drive the upper end of the packaging bag 13 to continue to move to the left. The upper end of the packaging bag 13 gradually moves out from between the two second conveyor belts 48 and gradually enters between the two third conveyor belts 49. After that, the two third conveyor belts 49 drive the upper end of the packaging bag 13 to continue to be conveyed to the left.

[0071] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
