DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0021] like Figure 1-Figure 10 An automated ammonium perchlorate packaging line is shown.

[0022] Example 1: Figure 1-Figure 10 As shown, the technical solution adopted by the present invention is as follows: an automated ammonium perchlorate packaging line includes a conveying mechanism and a filling mechanism.

[0023] The conveying mechanism is used to convey the packaging bottles. The conveying mechanism comprises a conveyor belt 1 and a connecting plate 2, and the conveyor belt 1 is installed between two connecting plates 2. The conveying mechanism is a prior art and will not be described in detail here.

[0024] The conveying mechanism is provided with a clamping assembly. The clamping assembly includes a first electric push rod 3 and a V-shaped clamping block 4. A mounting block is fixedly connected to each connecting plate 2, and a first electric push rod 3 is fixedly mounted on each mounting block, and the output ends of the two first electric push rods 3 are arranged opposite to each other. A V-shaped clamping block 4 is fixedly connected to the output end of each first electric push rod 3. When the first electric push rod 3 is started, the two V-shaped clamping blocks 4 approach each other, thereby clamping and fixing the packaging bottle on the conveyor belt 1. In the process of the V-shaped clamping block 4 clamping the packaging bottle, it has a positioning function for the packaging bottle, so that the bottle mouth of the packaging bottle is directly opposite to the filling mechanism.

[0025] The filling mechanism is arranged above the conveying mechanism for vertical movement. The filling mechanism includes a storage barrel 7, an elastic rubber ring 10 and a coil spring 11. The storage barrel 7 is arranged above the conveyor belt 1 for vertical movement. Ammonium perchlorate is contained in the storage barrel 7. Specifically, a support seat 5 is arranged on one side of the conveying mechanism. A first slide groove 9 is provided on the support seat 5, and a first slider 8 is slidably provided in the first slide groove 9, and the storage barrel 7 is fixedly connected to the first slider 8. A second driving component for driving the first slider 8 to move is installed on the top of the support seat 5.

[0026] In this embodiment, the second driving assembly includes a second electric push rod 6, which is fixedly mounted on the top of the support seat 5, with the telescopic end of the second electric push rod 6 pointing vertically downward, and the first slider 8 is fixedly connected to the telescopic end of the second electric push rod 6.

[0027] like Figure 5 , Figure 7 As shown, the elastic rubber ring 10 is installed at the lower end of the storage barrel 7, and the elastic rubber ring 10 is connected to the storage barrel 7. The lower part of the elastic rubber ring 10 gradually shrinks inward to form a filling port. The filling mechanism should be arranged in conjunction with the clamping assembly, and when the clamping assembly clamps and fixes the packaging bottle, the bottle mouth of the packaging bottle is directly opposite to the filling port.

[0028] The lower end of the elastic rubber ring 10 is bent inward to form a support platform. The coil spring 11 is arranged at the filling port on the elastic rubber ring 10, and the outer side of the coil spring 11 is arranged on the support platform. The outer part of the coil spring 11 is fixedly connected to the support platform. The end of the outer side of the coil spring 11 is fixedly connected to a vertical rod 18. A fixed block 14 is fixedly installed in the storage barrel 7, and a guide rod 19 is installed on the fixed block 14. A third slider is slidably arranged on the guide rod 19. The upper end of the vertical rod 18 is connected to the third slider.

[0029] When the coil spring 11 is tightened and deformed, the outer diameter of the coil spring 11 becomes smaller, and the third slider slides along the guide rod 19 toward the axis of the storage barrel 7. When the coil spring 11 is relaxed, the outer diameter of the coil spring 11 becomes larger, and the third slider slides along the guide rod 19 away from the axis of the storage barrel 7.

[0030] The inner ring of the coil spring 11 is provided with a winding wheel 12, and the winding wheel 12 is fixedly connected to the inner end of the coil spring 11. Fig.10 As shown, a groove is provided on the outer circumference of the winding wheel 12 , and the inner end of the coil spring 11 is fixedly disposed in the groove, so that the coil spring 11 can be tightly wound on the winding wheel 12 .

[0031] A connecting shaft 22 is rotatably installed in the storage barrel 7, and the connecting shaft 22 is rotatably connected to the winding wheel 12. Specifically, a slot is provided on the winding wheel 12, and the lower end of the connecting shaft 22 extends into the slot. A rotation groove is provided on the inner wall of the slot, and a flange is fixed to the lower end of the connecting shaft 22, and the flange is rotatably provided in the rotation groove.

[0032] A limit assembly is provided between the connecting shaft 22 and the winding wheel 12. The limit assembly includes a spline block 25. A spline groove 26 is provided in the winding wheel 12, and the spline groove 26 is connected to the slot. The spline groove 26 extends upward into the connecting shaft 22. The spline block 25 is arranged in cooperation with the spline groove 26. A third electric push rod 24 is fixedly mounted on the connecting shaft 22, and the output end of the third electric push rod 24 is vertically downward. The spline block 25 is fixedly connected to the output end of the third electric push rod 24.

[0033] The third electric push rod 24 extends, so that the spline block 25 extends into the spline groove 26 on the winding wheel 12. When the connecting shaft 22 rotates, the connecting shaft 22 drives the winding wheel 12 to rotate through the spline block 25, thereby tightening the coil spring 11, so that the coil spring 11 is gradually wound around the winding wheel 12. The outer diameter of the coil spring 11 is reduced, and then the lower end of the elastic rubber ring 10 is reduced, and the filling port becomes smaller. Then the first slider 8 moves downward, and the lower end of the elastic rubber ring 10 extends into the packaging bottle directly below the storage barrel 7.

[0034] The third electric push rod 24 is shortened, so that the spline block 25 moves up and then escapes from the spline groove 26 on the winding wheel 12. After the winding wheel 12 loses the limit of the spline block 25, the coil spring 11 gradually relaxes under its own elasticity, and the outer diameter of the coil spring 11 becomes larger. The coil spring 11 drives the lower end of the elastic rubber ring 10 to become larger, and the filling port becomes larger. Until the lower end of the elastic rubber ring 10 abuts against the inner wall of the bottle mouth of the packaging bottle, the filling port is adapted to the bottle mouth of the packaging bottle. A gap appears on the coil spring 11, and then the ammonium perchlorate in the storage barrel 7 falls into the packaging bottle below through the gap on the coil spring 11. Prevent the ammonium perchlorate powder in the storage barrel 7 from escaping into the air, and ensure the safety of the filling process.

[0035] A second slider 21 is provided in the storage barrel 7, and a second motor 20 is installed on the second slider 21. The motor shaft of the second motor 20 is vertically arranged downward and fixedly connected to the upper end of the connecting shaft 22. The second motor 20 drives the connecting shaft 22 to rotate, and the winding wheel 12 rotates, thereby tightening the coil spring 11.

[0036] Working principle: Initially, the spline block 25 extends into the spline groove 26 on the winding wheel 12, and the coil spring 11 is in the winding state. The coil spring 11 is wound around the winding wheel 12 in sequence. At this time, Fig. 9 As shown, the dotted line L in the figure is the edge of the support platform, and there is a gap between the outer end of the coil spring 11 and the inner wall of the elastic rubber ring 10, but the gap is above the support platform, so the filling port is blocked by the coil spring 11, and the outer diameter of the lower end of the storage barrel 7 is the smallest, and the ammonium perchlorate in the storage barrel 7 cannot flow out through the filling port.

[0037] When in use, the packaging bottle is placed on the conveyor belt 1, and the conveyor belt 1 transports the packaging bottle to the bottom of the filling mechanism. The first electric push rod 3 is started to make the V-shaped clamping block 4 move close to the packaging bottle. The two V-shaped clamping blocks 4 clamp the packaging bottle and fix the bottle mouth of the packaging bottle to be directly below the filling port.

[0038] After that, the second electric push rod 6 is started to move the first slider 8 downward, and the filling mechanism is moved downward, so that the lower end of the elastic rubber ring 10 extends into the packaging bottle. The third electric push rod 24 is started to move the spline block 25 upward, and then the spline block 25 is disengaged from the spline groove 26 on the winding wheel 12. After losing the limit of the spline block 25, the coil spring 11 is deformed under the action of its own elasticity, and the outer diameter of the coil spring 11 becomes larger, so that the lower end of the elastic rubber ring 10 becomes larger, and the filling port becomes larger until the elastic rubber ring 10 is against the inner wall of the packaging bottle. The filling port is automatically adapted to the bottle mouth of the packaging bottle. A gap appears on the coil spring 11, and the ammonium perchlorate in the storage barrel 7 falls into the packaging bottle through the gap on the coil spring 11.

[0039] The filling port automatically adapts to the bottle mouth of the packaging bottle and the packaging bottles of different sizes, which is beneficial to prevent the ammonium perchlorate powder from escaping into the air during the filling process and ensure the safety of production. It also improves the adaptability of the filling mechanism, helps to improve production efficiency, and helps to improve the automation level of ammonium perchlorate packaging.

[0040] After the filling is completed, the third electric push rod 24 is started, so that the spline block 25 moves downward and extends into the spline groove 26 on the winding wheel 12. The second motor 20 is started, the connecting shaft 22 rotates, and the connecting shaft 22 drives the winding wheel 12 to rotate through the spline block 25, thereby tightening the coil spring 11, so that the coil spring 11 is gradually wound around the winding wheel 12, the outer diameter of the winding wheel 12 becomes smaller, the lower end of the elastic rubber ring 10 gradually becomes smaller, and the filling port is gradually blocked by the coil spring 11. Then the first slider 8 is moved upward, and the elastic rubber ring 10 is removed from the packaging bottle.

[0041] Afterwards, the first electric push rod 3 is started, the V-shaped clamping block 4 moves away from the packaging bottle to release the limit on the packaging bottle, the packaging bottle filled with ammonium perchlorate is removed, and the new packaging bottle moves to the bottom of the filling mechanism.

[0042] Embodiment 2: This embodiment is an improvement based on embodiment 1.

[0043] A connecting block 13 is provided in the material storage barrel 7, and first driving assemblies are provided at both ends of the connecting block 13. The first driving assembly drives the connecting block 13 to move. The first driving assembly includes a first motor 15 and an eccentric rod 17. A fixing plate 16 is fixedly installed on the inner wall of the material storage barrel 7, and the first motor 15 is fixedly installed on the fixing plate 16, and the motor shaft of the first motor 15 is vertically arranged. One end of the eccentric rod 17 is rotationally connected to the motor shaft of the first motor 15, and the other end of the eccentric rod 17 is rotationally connected to the end of the connecting block 13 via a rotating shaft. The two first motors 15 are located on the same side of the corresponding eccentric rod 17. Figure 5 As shown, the first motor 15 is located at the left end of the corresponding eccentric rod 17.

[0044] The connecting block 13 is provided with a second slide groove 23, the second slider 21 is in an I-shaped shape, the vertical portion of the second slider 21 is slidably arranged in the second slide groove 23, and the horizontal portion of the second slider 21 is in sliding contact with the connecting block 13. The second motor 20 is installed on the upper side of the second slider 21, the motor shaft of the second motor 20 passes through the vertical portion and is fixedly connected to the upper end of the connecting shaft 22, and the motor shaft of the second motor 20 is rotationally matched with the second slider 21. A fourth electric push rod 27 is arranged in the second slide groove 23, the fourth electric push rod 27 is fixedly installed on the connecting block 13, and the telescopic end of the fourth electric push rod 27 is fixedly connected to the vertical portion of the second slider 21.

[0045] When the first driving assembly drives the connecting block 13 to move, the connecting block 13 drives the second slider 21 to move synchronously, thereby moving the connecting shaft 22 and the winding wheel 12. The winding wheel 12 moves parallel to the circular trajectory, causing the coil spring 11 to shake, which is conducive to the smooth and uniform fall of the ammonium perchlorate in the storage barrel 7.

[0046] Working principle: Initially, the spline block 25 extends into the spline groove 26 on the winding wheel 12, and the coil spring 11 is in the winding state. The coil spring 11 is wound around the winding wheel 12 in sequence. At this time, Fig. 9 As shown, the dotted line L in the figure is the edge of the support platform, and there is a gap between the outer end of the coil spring 11 and the inner wall of the elastic rubber ring 10, but the gap is above the support platform, so the filling port is blocked by the coil spring 11, and the outer diameter of the lower end of the storage barrel 7 is the smallest, and the ammonium perchlorate in the storage barrel 7 cannot flow out through the filling port.

[0047] When in use, the packaging bottle is placed on the conveyor belt 1, and the conveyor belt 1 transports the packaging bottle to the bottom of the filling mechanism. The first electric push rod 3 is started to make the V-shaped clamping block 4 move close to the packaging bottle. The two V-shaped clamping blocks 4 clamp the packaging bottle and fix the bottle mouth of the packaging bottle to be directly below the filling port.

[0048] After that, the second electric push rod 6 is started to move the first slider 8 downward, and the filling mechanism is moved downward, so that the lower end of the elastic rubber ring 10 extends into the packaging bottle. The third electric push rod 24 is started to move the spline block 25 upward, and then the spline block 25 is disengaged from the spline groove 26 on the winding wheel 12. After losing the limit of the spline block 25, the coil spring 11 is deformed under the action of its own elasticity, and the outer diameter of the coil spring 11 becomes larger, so that the lower end of the elastic rubber ring 10 becomes larger, and the filling port becomes larger until the elastic rubber ring 10 is against the inner wall of the packaging bottle. The filling port is automatically adapted to the bottle mouth of the packaging bottle. A gap appears on the coil spring 11, and the ammonium perchlorate in the storage barrel 7 falls into the packaging bottle through the gap on the coil spring 11.

[0049] The fourth electric push rod 27 is started, and the fourth electric push rod 27 pushes the second slider 21 to slide along the second slide groove 23, and the second motor 20, the connecting shaft 22 and the winding wheel 12 move, so that the winding wheel 12 is offset to one side of the axis of the filling port.

[0050] Then start the first motor 15, the first motor 15 drives the eccentric rod 17 to rotate, and then the connecting block 13 moves, the connecting shaft 22 moves, and the connecting shaft 22 drives the winding wheel 12 to move, so that the coil spring 11 shakes, which is conducive to the falling of the ammonium perchlorate in the storage barrel 7 and the uniform falling of the ammonium perchlorate in the storage barrel 7 into the packaging bottle.

[0051] After the filling is completed, the third electric push rod 24 is started, so that the spline block 25 moves downward and extends into the spline groove 26 on the winding wheel 12. The second motor 20 is started, the connecting shaft 22 rotates, and the connecting shaft 22 drives the winding wheel 12 to rotate through the spline block 25, thereby tightening the coil spring 11, so that the coil spring 11 is gradually wound around the winding wheel 12, the outer diameter of the winding wheel 12 becomes smaller, the lower end of the elastic rubber ring 10 gradually becomes smaller, and the filling port is gradually blocked by the coil spring 11. Then the first slider 8 is moved upward, and the elastic rubber ring 10 is removed from the packaging bottle.

[0052] Afterwards, the first electric push rod 3 is started, the V-shaped clamping block 4 moves away from the packaging bottle to release the limit on the packaging bottle, the packaging bottle filled with ammonium perchlorate is removed, and the new packaging bottle moves to the bottom of the filling mechanism.
