Description

Technical Field

[0001] The 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, a white crystalline powder, which is deliquescent. Ammonium perchlorate is a strong oxidant, and will explode when mixed with reducing agents, organic matter, flammable substances such as sulfur, phosphorus or metal powder. It is dangerous to cause combustion and explosion when in contact with strong acid. It is used to make explosives, fireworks, and as an analytical reagent.

[0003] As an important oxidant, the stability of ammonium perchlorate's packaging process directly affects production efficiency and product safety. Traditional packaging equipment generally uses mechanical grippers to directly fix the bag mouth of the packaging bag, but there are the following technical defects: 1. The mechanical grippers are not equipped with a wrinkle removal mechanism during the clamping process, resulting in wrinkles at the bag mouth. For example, for a packaging bag with a diameter of 40cm, if there are 3 wrinkles at the bag mouth, the effective volume will be reduced by about 8-12%, seriously affecting the filling accuracy. 2. In the existing elastic clamping device, in the later stage of filling, as the weight of the material increases (the typical ammonium perchlorate packaging weight is 25-50kg), the bag body slides down, causing the clamping force to decay, and it is easy to loosen during the loading process. 3. The conventional rotary clamping mechanism adopts a synchronous expansion method, which cannot ensure the horizontal consistency of multiple clamping points. When the clamping height deviates, the filling port and the center of the bag bottom are offset by a large amount, resulting in uneven material distribution. Summary of the invention

[0014] The invention discloses a method for using a packaging device on an ammonium perchlorate production line: the bag opening of the packaging bag is located below a fixed plate, and a plurality of sleeves and a plurality of baffles are located inside the bag opening of the packaging bag, and a driving component is started to rotate a rotating ring. When the rotating ring rotates, a connecting rod drives a sliding seat, a sleeve and a baffle to move in a direction away from the axis of the rotating ring, and the sleeve and a magnet move relative to each other. When the sleeve and the baffle are tensioned by the bag opening of the packaging bag, the sleeve and the baffle are limited by the bag opening of the packaging bag. When the sliding seat continues to move in a direction away from the axis of the rotating ring, the sleeve and the baffle gradually approach the vertical part of the connecting seat. When the sleeve and the baffle gradually approach the vertical part of the connecting seat, the magnet separates from the sleeve, and the limiting rod enters the limiting groove. When the baffle moves to the maximum stroke, the driving component is closed, the rotating ring stops moving, and then the packaging bag is moved downward. When the upper end of the packaging bag is located below the sleeve, the packaging bag The ring is no longer blocked and slides back on the connecting seat. After the ring slides back on the connecting seat, the magnet can no longer magnetically attract the ring, and the limit rod withdraws from the limit groove, and the ring can move up and down and rotate on the guide rod. Due to the eccentric arrangement of the ring and the guide rod, the gap between the ring and the stop rod gradually becomes smaller during the downward rotation of the ring. When the outer edge of the ring contacts the outer side of the packaging bag, the ring and the stop rod can clamp the packaging bag and inject a certain amount of ammonium perchlorate into the barrel. A certain amount of ammonium perchlorate enters the packaging bag through the barrel. During the process of ammonium perchlorate entering the packaging bag, the packaging bag has a tendency to move downward. Under the friction between the ring and the packaging bag, the ring has a tendency to rotate downward, that is, when the packaging bag moves downward, the ring rotates downward, and the squeezing force of the ring and the stop rod on the packaging bag increases when the ring rotates downward, thereby preventing the packaging bag from slipping between the stop rod and the ring.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. When the collar rotates downward during the filling process, its eccentric structure reduces the clamping gap to achieve automatic clamping of the bag mouth.

[0016] 2. Flatten the opening of the bag before clamping it to avoid wrinkles at the opening of the bag, which may reduce the overall height of the bag and affect its capacity.

[0017] 3. Before clamping the packaging bag, the height of the bag opening can be adjusted to ensure that the bag opening is level, thereby avoiding the bag from tilting and the uneven distribution of materials caused by a large offset between the bag opening and the center of the bag bottom.

[0018] 4. Through the synergistic effect of magnetic adsorption and the limit rod, the clamping mechanism can be accurately switched between the bag support mode and the locking mode, with high clamping efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] The sliding seat 8 is connected to the connecting rod 7. One end of the connecting rod 7 is rotatably connected to the rotating ring 4, and the other end of the connecting rod 7 is rotatably connected to the sliding seat 8.

[0043] The upper assembly includes a slider 19 , which is elastically slidably connected to the straight portion of the connecting seat 13 .

[0044] A slide groove 18 is provided on the straight portion of the connecting seat 13, and a slider 19 is slidably engaged in the slide groove 18.

[0048] 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 sleeve ring 11 away from the axis of the rotating ring 4 .

[0049] 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 .

[0050] A lower spring 17 is arranged between the baffle rod 12 and the vertical part of the connecting seat 13. The lower spring 17 is sleeved on the sliding 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 sliding rod 30 and the lower spring 17 are located in the positioning sleeve 15.

[0051] A limiting rod 32 is fixed to the lower end of the straight portion of the connecting seat 13 , and 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 .

[0052] A groove is formed 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, and 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 a part of the rotating roller 28 extends to the outside of the baffle rod 12. A rubber sleeve 27 is fixed to the outside of the rotating roller 28.

[0053] A second switch 26 is fixed in the slide groove 18, 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.

[0054] When ammonium perchlorate is packaged, the bag 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 bag opening of the packaging bag 34, and 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.

[0055] 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.

[0056] After the collar 11 and the stopper 12 tighten the bag opening of the packaging bag 34, the collar 11 and the stopper 12 are limited by the bag 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 stopper 12 gradually approach the vertical portion of the connecting seat 13, and the upper spring 16 and the lower spring 17 are compressed.

[0057] As the collar 11 and the stopper 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.

[0058] When the stopper 12 contacts the positioning sleeve 15, the slider 19 triggers the first switch 25, and the controller turns off the first motor 3 through the first driver, and the rotating ring 4 stops moving. At the same time, the controller starts the second motor 29 through the second driver, and when the second motor 29 drives the rotating roller 28 and the rubber sleeve 27 to rotate, the packaging bag 34 moves downward as a whole under the friction between the rubber sleeve 27 and the packaging bag 34, and the wrinkles of the bag opening of the packaging bag 34 are stretched by the friction force, so that the bag opening of the packaging bag 34 is flattened.

[0059] When the upper end of the packaging bag 34 is located below the ring 11, the packaging bag 34 no longer blocks the ring 11. Under the elastic force of the upper spring 16, the ring 11 slides and resets on the connecting seat 13. After the ring 11 slides and resets on the connecting seat 13, the second switch 26 is triggered, and the second switch 26 sends a signal to the controller, and the second motor 29 is turned off.

[0060] 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 and reset on the connecting seat 13 .

[0061] Since the position of the sliding seat 8 has changed, 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 and the guide rod 20 are eccentrically arranged, the gap between the collar 11 and the stop rod 12 gradually becomes smaller during the collar 11's downward rotation. When the outer edge of the collar 11 contacts the outer side of the packaging bag 34, the collar 11 and the stop rod 12 can clamp the packaging bag 34.

[0062] A certain amount of ammonium perchlorate is injected into the barrel 1, and the certain 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 friction 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. The collar 11 and the guide rod 20 are eccentrically designed. When the collar 11 rotates downward, the clamping force on the packaging bag 34 is increased due to the lever effect, thereby preventing the packaging bag 34 from slipping off between the stop rod 12 and the collar 11.

[0063] 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 direction of the rotating ring 4 when the rotating ring 4 rotates.

[0064] After 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.

[0065] 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 protection scope of the present invention.

The packaging device on an ammonium perchlorate production line according to claim 8, characterized in that: A second switch (26) is fixed in the slide groove (18); a first switch (25) is fixed at 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); both the first switch (25) and the second switch (26) are 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.

10. A method for using the packaging device on an ammonium perchlorate production line according to claim 1, characterized in that: The bag opening of the packaging bag (34) is located below the fixed plate (31), and a plurality of collars (11) and a plurality of baffles (12) are located inside the bag opening of the packaging bag (34). The driving assembly is started to rotate the rotating ring (4). When the rotating ring (4) rotates, the connecting rod (7) drives the sliding seat (8), the collar (11) and the baffles (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 baffles (12) tighten the bag opening of the packaging bag (34), the collar (11) and the baffles (12) are limited by the bag opening of the packaging bag (34) and move in a direction away from the axis of the rotating ring (4). ) continues to move in a direction away from the axis of the rotating ring (4), the collar (11) and the blocking rod (12) gradually approach the vertical portion of the connecting seat (13). 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). 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) moves 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 decreases during the downward rotation of the ring (11). 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).
