Detailed implementation mode

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0021] As Figures 1 - 13 shown, the powder packaging and transporting machine on the ammonium perchlorate production line.

[0022] Embodiment 1: As Figures 1 - 13 shown, the technical solution adopted by the present invention is as follows: The powder packaging and transporting machine on the ammonium perchlorate production line includes a first conveyor belt 1, a feed pipe 14 and a third limit rod 41.

[0023] The first conveyor belt 1 is installed between two side plates. The two side plates are the first side plate 3 and the second side plate 51 respectively. Limit blocks 2 for limiting the packaging bag 13 are installed on the inner sides of the first side plate 3 and the second side plate 51.

[0024] A feed barrel 5 is arranged above the first conveyor belt 1. The feed pipe 14 is installed at the lower end of the feed barrel 5. The lower end of the feed pipe 14 moves up and down relative to the first conveyor belt 1, so that the feed pipe 14 can be inserted into or removed from the packaging bag 13 on the first conveyor belt 1. The material in the feed barrel 5 enters the packaging bag 13 through the feed pipe 14.

[0025] In this embodiment, as Figure 8 shown, a second electric push rod 44 is installed 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 with a first connecting plate 6. The material barrel 5 is installed on the first connecting plate 6.

[0026] As Figure 2 shown, two first clamping units are symmetrically arranged on the blanking pipe 14. The first clamping unit is used to clamp the packaging bags 13 on both sides of the blanking pipe 14, so that the blanking pipe 14 is wrapped by the packaging bags 13.

[0027] Each first clamping unit includes two symmetrically arranged first limiting rods 16. A second fixing block 24 is fixedly installed on the outer side wall of the blanking pipe 14, and a second guiding block 19 slidably matched with the first limiting rod 16 is fixedly installed on the second fixing block 24. The second guiding block 19 is L-shaped, and a second guiding groove 20 is formed on the second guiding block 19. The first limiting rod 16 is fixedly connected with a rectangular block 26, and the rectangular block 26 is slidably arranged in the second guiding groove 20. The two second guiding blocks 19 in the same clamping unit are symmetrically arranged. A driving member for driving the first limiting rod 16 to move along the second guiding block 19 is installed on the blanking pipe 14.

[0028] The first limiting rod 16 moves downward along the vertical part of the second guiding block 19, and then the first limiting rod 16 moves close to the packaging bag 13 along the horizontal part of the second guiding block 19. The two first limiting rods 16 clamp the packaging bag 13, so that the blanking pipe 14 is wrapped by the packaging bag 13. The two first clamping units clamp the packaging bags 13 on both sides of the blanking pipe 14, so that the packaging bag 13 is wrapped around the blanking pipe 14, avoiding the material droplets in the packaging bag 13 from escaping upward through the gap between the packaging bag 13 and the blanking pipe 14.

[0029] In order to make the packaging bag 13 fit more closely to the blanking pipe 14 and avoid gaps between the packaging bag 13 and the blanking pipe 14. An arc surface is formed on the first limiting rod 16. A convex block 50 adapted to the arc surface of the first limiting rod 16 is fixed on the outer side wall of the blanking pipe 14. As Figure 13 shown, when the two first limiting rods 16 clamp the packaging bag 13, the arc surface of the first limiting rod 16 fits onto the convex block 50.

[0030] The driving member includes a first guiding block 17. A first fixing block 23 is fixedly installed on the outer side wall of the blanking pipe 14. One end of the first guiding block 17 is fixedly connected to a first rotating rod, and the first rotating rod is rotatably installed on the first fixing block 23. The other end of the first guiding block 17 is provided with a first guiding groove 18. The rectangular block 26 is connected to a cylindrical block 27, and the cylindrical block 27 is movably arranged in the first guiding groove 18. One end of each of the two first guiding blocks 17 close to each other is fixedly connected to a 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 fixing block 23, and the output shaft of the first motor 22 is fixedly connected to one of the first rotating rods.

[0031] The first motor 22 drives the corresponding first rotating rod to rotate, causing the corresponding first guiding block 17 to rotate. Under the action of the two first gears 21, the two first guiding blocks 17 rotate simultaneously, and the rotation directions of the two first guiding blocks 17 are opposite. The first guiding block 17 rotates around the first rotating rod, causing the rectangular block 26 to slide along the second guiding groove 20, and the cylindrical block 27 to move along the first guiding groove 18.

[0032] As Figure 8 shown, a first sliding hole is formed in the first side plate 3, and a first sliding seat 28 is slidably installed up and down in the first sliding hole. A fifth motor 45 is installed on the first side plate 3, and the output shaft of the fifth motor 45 is fixedly connected to a third threaded rod 46. The third threaded rod 46 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, and the third threaded rod 46 drives the first sliding seat 28, causing the first sliding seat 28 to move up and down along the first sliding hole.

[0033] As Figure 7 shown, a first connecting seat 4 is slidably and limitably arranged on the first sliding seat 28. A limiting groove slidably matched with the first sliding seat 28 is formed in the first connecting seat 4. A second driving component for driving the first connecting seat 4 to slide is arranged on the first sliding seat 28. The second driving component includes a second threaded rod 40 and a fourth motor 39. The second threaded rod 40 is rotatably installed on the first sliding seat 28. The fourth motor 39 is fixedly installed 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.

[0034] As Figure 5As shown, both ends of the first connection seat 4 are fixedly connected with second connection seats 29. A second sliding seat 30 and a connection block 31 are slidably arranged on each second connection seat 29. The connection block 31 is located on one side of the second sliding seat 30 close to the end of the first connection seat 4. A spring 34 is fixedly connected between the second sliding seat 30 and the connection block 31.

[0035] A first driving assembly for driving the second sliding seat 30 to move is arranged on the second connection seat 29. The first driving assembly includes a second motor 33 and a first threaded rod 32. The second motor 33 is fixedly installed on the second connection seat 29, the first threaded rod 32 is rotatably installed on the second connection seat 29, and the output shaft of the second motor 33 is fixedly connected with the first threaded rod 32.

[0036] Each connection block 31 is fixedly connected with a second connecting plate 38. Each second connecting plate 38 is fixedly connected with a third limiting rod 41.

[0037] The second motor 33 drives the first threaded rod 32 to rotate, so that the two second sliding seats 30 move away from each other. The second sliding seat 30 pushes the connection block 31 to move through the spring 34, and the two connection blocks 31 move away from each other, so that the two third limiting rods 41 move away from each other. The two third limiting rods 41 tighten the bag mouth of the packaging bag 13, so that the two sides of the bag mouth of the packaging bag 13 approach each other, and both sides of the bag mouth of the packaging bag 13 are in contact with the blanking pipe 14. Then the first clamping unit clamps the packaging bag 13 on both sides of the blanking pipe 14, so that the packaging bag 13 is wrapped around the blanking pipe 14.

[0038] When the first clamping unit clamps the packaging bag 13, the packaging bag 13 pulls the blanking pipe 14, so that the connection block 31 further compresses the spring 34 and moves closer to the second sliding seat 30.

[0039] A second clamping unit is arranged on each second connecting plate 38. The second clamping unit includes two symmetrically arranged second limiting rods 36. One end of the second limiting rod 36 is rotatably installed on the second connecting plate 38 through a second rotating rod. A second gear 37 is fixedly installed at one end of the second limiting rod 36. The second gear 37 is coaxially arranged with the corresponding second rotating rod, and the two second gears 37 are meshed. A third motor 35 is arranged on the second connecting plate 38, and the output shaft of the third motor 35 is drivingly connected with one of the second limiting rods 36.

[0040] After the first clamping unit clamps the packaging bags 13 on both sides of the blanking pipe 14, the third motor 35 is started. The third motor 35 drives the corresponding second limiting rod 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 blanking pipe 14, so that the packaging bag 13 is wrapped around the third limiting rod 41, and the two sides of the packaging bag 13 between the third limiting rod 41 and the blanking pipe 14 are mutually attached, thereby sealing the bag mouth of the packaging bag 13.

[0041] As Figure 6 shown, a first contact 42 and a second contact 43 are provided on the second sliding seat 30. 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 bag mouth of the packaging bag 13, as the second sliding seat 30 further moves, since the third limiting rod 41 cannot move further, the connecting block 31 moves close to the second sliding seat 30 against the elastic force of the spring 34, so that the connecting block 31 presses the first contact 42, and then the first motor 22 is started, so that the first clamping unit clamps the packaging bags 13 on both sides of the blanking pipe 14. When the first clamping unit clamps the packaging bag 13, it will cause the connecting block 31 to move further close to the second sliding seat 30, so that the connecting block 31 presses the second contact 43, and the third motor 35 is started, so that the second clamping unit clamps the packaging bag 13 on one side of the third limiting rod 41.

[0042] An exhaust assembly is provided on the blanking pipe 14. The exhaust assembly includes an exhaust pipe 15, and the exhaust pipe 15 is installed on the blanking pipe 14. An exhaust passage is opened in the side wall of the blanking pipe 14, and the upper end of the exhaust passage is communicated with the exhaust pipe 15. An air extraction port 25 communicated with the lower end of the exhaust pipe 15 is opened on the outer side wall of the blanking pipe 14.

[0043] Working principle: Initially, the rectangular block 26 is at the upper end of the vertical portion of the second guiding block 19, and the two first limiting rods 16 are far away from each other. The second limiting rod 36 is vertically upward, and the second limiting rod 36 is above the second gear 37.

[0044] During use, the packaging bag 13 is placed directly below the blanking pipe 14 on the first conveyor belt 1, and the packaging bag 13 is located between the two limiting blocks 2. And the blanking pipe 14 and the third limiting rod 41 both extend into the packaging bag 13.

[0045] Then, the second motor 33 is started, the first threaded rod 32 rotates, the first threaded rod 32 drives the second sliding seat 30 to move outwards, and the two second sliding seats 30 move away from each other. The second sliding seat 30 drives the connecting block 31 to move through the spring 34. The connecting block 31 drives the second connecting plate 38 to move, the second connecting plate 38 drives the third limiting rod 41 to move, and the two third limiting rods 41 move away from each other, gradually tightening the bag mouth of the packaging bag 13. The two sides of the bag mouth of the packaging bag 13 gradually approach, so that both sides of the upper end of the packaging bag 13 are in contact with the material discharge pipe 14.

[0046] After the third limiting rod 41 tightens the bag mouth of the packaging bag 13, as the second sliding seat 30 continues to move outwards, since the third limiting rod 41 cannot move outwards anymore, the spring 34 is further compressed, the second sliding seat 30 approaches the connecting block 31 until the connecting block 31 presses 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 downwards along the vertical part 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 close to the packaging bag 13 along the horizontal part of the second guide block 19. Until the two first limiting rods 16 clamp the packaging bag 13, the packaging bags 13 on both sides of the material discharge pipe 14 are clamped, and the packaging bag 13 is wrapped around the material discharge pipe 14, preventing the droplets in the packaging bag 13 from escaping through the gap between the packaging bag 13 and the material discharge pipe 14, and can automatically adapt to the size of the packaging bag 13.

[0047] During the process of the two first limiting rods 16 clamping the packaging bag 13, the packaging bag 13 will pull the third limiting rod 41 to move inwards, further compressing the spring 34 and making the connecting block 31 move closer to the second sliding seat 30, and the connecting block 31 presses the second contact 43. The third motor 35 is started, and the second limiting rod 36 rotates until the two second limiting rods 36 clamp the packaging bag 13 on the side of the third limiting rod 41 close to the material discharge pipe 14, so that the packaging bag 13 wraps around the third limiting rod 41. The two sides of the packaging bag 13 between the third limiting rod 41 and the material discharge pipe 14 are in contact with each other. At this time, the bag mouth of the packaging bag 13 is sealed, effectively preventing the material droplets in the packaging bag 13 from escaping.

[0048] Afterwards, the material is poured into the packaging bag 13 through the feeding tube 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 moves 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 feeding tube 14 and the first limiting rod 16, so that the bag mouth of the packaging bag 13 remains sealed, and the material foam stirred in the packaging bag 13 is prevented from escaping upward. The sliding of the packaging bag 13 relative to the feeding tube 14 is conducive to making the material fall into the packaging bag 13 evenly. And as the packaging bag 13 moves, the material in the packaging bag 13 shakes accordingly, further improving the uniformity of material filling.

[0049] It should be noted that after a certain amount of material is poured into the packaging bag 13, the lower end of the packaging bag 13 becomes difficult to move. Then, 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.

[0050] During the filling process, the air suction port 25 at the lower end of the discharge pipe 14 is located in the packaging bag 13. Since the bag opening in the packaging bag 13 is sealed, the air in the packaging bag 13 can be discharged through the air suction port 25, the exhaust channel, and the air suction pipe 15, so that the material can smoothly enter the packaging bag 13. It should be noted that the air suction pipe 15 can be connected to an external collection mechanism to collect the material droplets discharged through the air suction pipe 15. Of course, the air in the packaging bag 13 can also be sucked by the first conveyor belt 1 through an air pump to prevent the air in the packaging bag 13 from opening the bag opening. The collection mechanism and the air pump are both existing technologies and are not described here.

[0051] After the filling is completed, the material barrel 5 is moved upward by the second electric push rod 44, and the feed tube 14 is moved upward, and the feed tube 14 is pulled out of the packaging bag 13. When the feed tube 14 is pulled out of the packaging bag 13, the spring 34 pushes the connection block 31 to move outward, and the third limit rod 41 moves outward, so that the upper end of the packaging bag 13 remains in a tensioned state, and the bag mouth of the packaging bag 13 is still in a sealed state. The connection block 31 moves outward so that the connection block 31 releases the squeezing of the first contact 42 and the second contact 43. After that, the first motor 22 and the third motor 35 are started, so that the first limit rod 16 and the second limit rod 36 are reset to release the clamping of the packaging bag 13.

[0052] 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 .

[0053] Embodiment 2: This embodiment is an improvement based on Embodiment 1.

[0054] An auxiliary transportation component is provided above the first conveyor belt 1. The auxiliary transportation component 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. A slider 9 is slidably arranged in the second sliding hole, and an electric slide rail 8 for driving the slider 9 to move is arranged in the second sliding hole.

[0055] A first electric push rod 10 is installed on the slider 9. A connecting frame 11 is installed at 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 installed 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 installed on the support block 7. Third conveyor belts 49 are installed on one sides of the two first clamping plates 12 that are close to each other.

[0056] After the third limiting rod 41 is drawn out of the packaging bag 13, the first electric push rod 10 is started to move the second clamping plate 47 close to the packaging bag 13 until the upper end of the packaging bag 13 is clamped by the two second clamping plates 47.

[0057] After that, the first conveyor belt 1 and the electric slide rail 8 are started. As Figure 10 shown in the direction, the first conveyor belt 1 drives the lower end of the packaging bag 13 to be conveyed leftward. The electric slide rail 8 drives the slider 9 to move leftward. The slider 9 drives the second clamping plate 47 to move leftward. The second clamping plate 47 drives the upper end of the packaging bag 13 to move leftward, so that the packaging bag 13 moves leftward stably. The moving speed of the first conveyor belt 1 and the moving speed of the slider 9 are set in cooperation to keep the packaging bag 13 stable.
