Description

Technical Field

[0001] The present invention relates to the technical field of packaging, and in particular to a packaging device on an ammonium perchlorate production line and a use method thereof. Background Art

[0002] Ammonium perchlorate is an inorganic compound that appears as a deliquescent white crystalline powder. It is a strong oxidizing agent and can explode when mixed with reducing agents, organic matter, or flammable materials such as sulfur, phosphorus, or metal powders. Contact with strong acids can cause combustion and explosion. It is used in the manufacture of explosives, fireworks, and as an analytical reagent.

[0003] Ammonium perchlorate is an important oxidizing agent, and the stability of its packaging process directly affects production efficiency and product safety. Traditional packaging equipment generally uses mechanical grippers to directly secure the bag opening, but this has the following technical flaws: 1. The mechanical grippers lack a wrinkle removal mechanism during the clamping process, resulting in wrinkles at the bag opening. For example, for a 40cm diameter bag, for every three wrinkles at the bag opening, the effective volume will decrease by approximately 8-12%, seriously affecting filling accuracy. 2. With existing elastic clamping devices, in the later stages of filling, as the weight of the material increases (typical ammonium perchlorate packages weigh 25-50kg), the bag slides downward, causing the clamping force to weaken and the bag to easily loosen during filling. 3. Conventional rotary clamping mechanisms use a synchronous expansion method, which cannot ensure horizontal consistency at multiple clamping points. When the clamping height deviates, the filling opening and the center of the bag bottom are significantly offset, resulting in uneven material distribution. Summary of the Invention

[0046] A slide groove 18 is provided on the straight part of the connecting seat 13, and a slider 19 is slidably engaged in the slide groove 18.

[0049] A magnet 10 corresponding to the clamping unit is fixed to the lower end of the fixing plate 31 . The magnet 10 is located above the collar 11 , and the magnet 10 magnetically attracts the collar 11 .

[0050] The lower assembly includes a blocking rod 12 , which is elastically slidably connected to the vertical portion of the connecting seat 13 , and a side of the blocking rod 12 away from the axis of the rotating ring 4 is flush with a side of the collar 11 away from the axis of the rotating ring 4 .

[0051] A sliding rod 30 is fixed on the blocking rod 12 . The sliding rod 30 passes through the vertical portion of the connecting seat 13 . The sliding rod 30 is slidably connected to the vertical portion of the connecting seat 13 .

[0052] A lower spring 17 is provided between the baffle rod 12 and the vertical part of the connecting seat 13. The lower spring 17 is sleeved on the slide rod 30. One end of the lower spring 17 is fixedly connected to the baffle rod 12, and the other end of the lower spring 17 is fixedly connected to the vertical part of the connecting seat 13. A positioning sleeve 15 is fixed on the side of the vertical part of the connecting seat 13 facing the baffle rod 12, and the slide rod 30 and the lower spring 17 are located in the positioning sleeve 15.

[0053] A limiting rod 32 is fixed to the lower end of the straight portion of the connecting seat 13 . The length direction of the limiting rod 32 is parallel to the sliding direction of the upper assembly. A limiting groove 33 corresponding to the limiting rod 32 is formed at the upper end of the collar 11 .

[0054] A groove is provided on the side of the baffle rod 12 away from the axis of the rotating ring 4, and a second motor 29 is fixed in the groove. A rotating roller 28 is concentrically fixed on the output shaft of the second motor 29. The axis of the rotating roller 28 is perpendicular to the axis of the baffle rod 12. The baffle rod 12 is vertically arranged, and the rotating roller 28 partially extends to the outside of the baffle rod 12. A rubber sleeve 27 is fixed to the outside of the rotating roller 28.

[0055] A second switch 26 is fixed in the slide groove 18, and a first switch 25 is fixed to one end of the positioning block 14 facing the slider 19. The slider 19 is located between the first switch 25 and the second switch 26. The first switch 25 and the second switch 26 are both touch switches. The first switch 25 and the second switch 26 are electrically connected to the controller, the first motor 3 is electrically connected to the first driver, the second motor 29 is electrically connected to the second driver, and the first driver and the second driver are electrically connected to the controller.

[0056] When ammonium perchlorate is packaged, the opening of the packaging bag 34 is located below the fixed plate 31, and the multiple rings 11 and the multiple blocking rods 12 are located in the opening of the packaging bag 34. The first motor 3 is started, and the first motor 3 rotates the rotating ring 4 through the gear 23 and the gear ring 24.

[0057] When the rotating ring 4 rotates, the connecting rod 7 drives the sliding seat 8, the collar 11 and the blocking rod 12 to move in a direction away from the axis of the rotating ring 4, and the collar 11 and the magnet 10 move relative to each other.

[0058] After the collar 11 and the stop rod 12 tighten the opening of the packaging bag 34, the collar 11 and the stop rod 12 are restrained by the opening of the packaging bag 34. As the sliding seat 8 continues to move away from the axis of the rotating ring 4, the slider 19, the collar 11 and the stop rod 12 gradually approach the vertical portion of the connecting seat 13, and the upper spring 16 and the lower spring 17 are compressed.

[0059] As the collar 11 and the blocking rod 12 gradually approach the vertical portion of the connecting seat 13, the magnet 10 separates from the collar 11, and the limiting rod 32 enters the limiting groove 33. After the limiting rod 32 enters the limiting groove 33, the collar 11 is stopped from rotating.

[0060] When the stop bar 12 contacts the positioning sleeve 15, the slider 19 triggers the first switch 25, and the controller turns off the first motor 3 via the first driver, causing the rotating ring 4 to stop moving. Simultaneously, the controller activates the second motor 29 via the second driver. As the second motor 29 drives the rotating roller 28 and the rubber sleeve 27 to rotate, the friction between the rubber sleeve 27 and the packaging bag 34 causes the packaging bag 34 to move downward as a whole. This friction stretches the wrinkles at the bag opening, flattening the bag opening.

[0061] When the upper end of the packaging bag 34 is located below the collar 11, the packaging bag 34 no longer blocks the collar 11. Under the elastic force of the upper spring 16, the collar 11 slides and resets on the connecting seat 13. After the collar 11 slides and resets on the connecting seat 13, the second switch 26 is triggered. The second switch 26 sends a signal to the controller, and the second motor 29 is turned off.

[0062] Since the clamping units are all provided with the second motors 29 , the rotating rollers 28 and the rubber sleeves 27 , when all the second motors 29 are stopped, the upper end of the packaging bag 34 is flush with the horizontal plane, and all the rings 11 slide back on the connecting seat 13 .

[0063] Due to the change in the position of the sliding seat 8, the magnet 10 can no longer magnetically attract the collar 11 after the collar 11 slides back on the connecting seat 13. At this time, the limiting rod 32 withdraws from the limiting groove 33, and the collar 11 can move up and down the guide rod 20 and rotate. Since the collar 11 is eccentrically arranged with the guide rod 20, the gap between the collar 11 and the stop rod 12 gradually decreases during the downward rotation of the collar 11. When the outer edge of the collar 11 contacts the outside of the packaging bag 34, the collar 11 and the stop rod 12 can clamp the packaging bag 34.

[0064] A fixed amount of ammonium perchlorate is injected into the barrel 1, and the fixed amount of ammonium perchlorate enters the packaging bag 34 through the barrel 1. During the process of ammonium perchlorate entering the packaging bag 34, the packaging bag 34 has a tendency to move downward. Under the action of the friction between the ring 11 and the packaging bag 34, the ring 11 has a tendency to rotate downward, that is, when the packaging bag 34 moves downward, the ring 11 rotates downward. The ring 11 and the guide rod 20 are eccentrically designed. When the ring 11 rotates downward, the lever effect increases the clamping force on the packaging bag 34, thereby preventing the packaging bag 34 from slipping off between the stop rod 12 and the ring 11.

[0065] After the fixed amount of ammonium perchlorate has completely entered the packaging bag 34 , the first motor 3 is started, so that the plurality of clamping units move toward the axis of the rotating ring 4 when the rotating ring 4 rotates.

[0066] When the sliding seat 8 is reset, the ring 11 rotates upward under the magnetic attraction of the magnet 10. After the ring 11 rotates upward and resets, the blocking rod 12 is reset under the elastic force of the lower spring 17, and the packaging bag 34 containing ammonium perchlorate can be removed from the limiting ring 5.

[0067] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.

When the rotating ring (4) rotates, the connecting rod (7) drives the sliding seat (8), the collar (11) and the baffle (12) to move in a direction away from the axis of the rotating ring (4). The collar (11) and the magnet (10) move relative to each other. When the collar (11) and the baffle (12) tighten the opening of the packaging bag (34), the collar (11) and the baffle (12) are limited by the opening of the packaging bag (34). ) continues to move in the direction away from the axis of the rotating ring (4), the collar (11) and the blocking rod (12) gradually approach the vertical part of the connecting seat (13). As the collar (11) and the blocking rod (12) gradually approach the vertical part of the connecting seat (13), the magnet (10) separates from the collar (11), and the limiting rod (32) enters the limiting groove (33). When the blocking rod (12) moves to the maximum stroke, the driving assembly is closed, the rotating ring (4) stops moving, and then the packaging bag (34) is made to move downward. When the upper end of the packaging bag (34) is located below the collar (11), the packaging bag (34) no longer blocks the collar (11), and the collar (11) is moved downward. The ring (11) slides and resets on the connecting seat (13). After the ring (11) slides and resets on the connecting seat (13), the magnet (10) can no longer magnetically adsorb the ring (11), the limiting rod (32) withdraws from the limiting groove (33), and the ring (11) can move up and down on the guide rod (20) and rotate. Since the ring (11) and the guide rod (20) are eccentrically arranged, the gap between the ring (11) and the stop rod (12) gradually becomes smaller during the process of the ring (11) rotating downward. When the outer edge of the ring (11) contacts the outer side of the packaging bag (34), the ring (11) and the stop rod (12) can clamp the packaging bag (34). A fixed amount of ammonium perchlorate is injected into the barrel (1), and the fixed amount of ammonium perchlorate enters the packaging bag (34) through the barrel (1). During the process of the ammonium perchlorate entering the packaging bag (34), the packaging bag (34) has a tendency to move downward. Under the action of the friction force between the collar (11) and the packaging bag (34), the collar (11) has a tendency to rotate downward, that is, when the packaging bag (34) moves downward, the collar (11) rotates downward. When the collar (11) rotates downward, the squeezing force of the collar (11) and the stop rod (12) on the packaging bag (34) increases, thereby preventing the packaging bag (34) from slipping off between the stop rod (12) and the collar (11).
