Description

Technical Field

[0001] The present invention relates to the technical field of calcium carbonate, and particularly relates to a calcium carbonate production and packaging system and a packaging method. Background Art

[0002] Calcium carbonate is an inorganic compound, commonly known as limestone, calcite, marble, and chalk. It is a neutral compound that is basically insoluble in water and soluble in acid. It is an important building material. With the progress and development of science and technology and the influence of relevant national policies, the uses of calcium carbonate will surely become more and more extensive, and the demand will also increase. Currently, when preparing calcium carbonate, the ground calcium carbonate powder needs to be filled into valve bags for packaging. However, the following problems often occur during the bagging process:

[0003] 1. In the prior art, when bagging calcium carbonate, generally, workers need to put the valve bag on the filling nozzle manually, and then fill the calcium carbonate into the valve bag through filling equipment. The manual bagging method is not only time-consuming and laborious with low efficiency, but also the manual operation is prone to inhaling dust, increasing the harm to the health of workers.

[0004] 2. In the prior art, when bagging calcium carbonate, since the valve bag is connected to the filling nozzle, when filling calcium carbonate into the bag, the air in the bag will flow out through the gap at the mouth of the valve bag. Due to the small area of the gap, the air flow rate is fast, which will blow out some calcium carbonate in the bag, making it suspended in the air as dust. This not only causes waste but also endangers the health of workers.

[0005] 3. In the prior art, after the calcium carbonate bagging is completed, the valve bag needs to be heat-sealed. Since some calcium carbonate will remain at the opening of the valve bag during filling, the opening of the valve bag cannot be bonded together during sealing, resulting in ineffective sealing and leakage of the bag.

[0006] 4. In the prior art, after the calcium carbonate is sealed, workers need to manually remove the whole bag of calcium carbonate and place it on the conveyor belt for transportation. However, when workers remove the bagged calcium carbonate, they generally throw it on the conveyor belt, and in severe cases, the valve bag will be cracked, resulting in leakage of the bag. Summary of the Invention

When the convex block moves below the right vertical side plate, the slider drives the convex block to extend below the right vertical side plate under the action of the first spring.

[0016] The present invention also provides a method for packaging calcium carbonate with the above calcium carbonate production packaging system, including the following steps:

[0017] S1. Place the finished calcium carbonate powder in the feeding assembly and place the valve bag in the receiving assembly;

[0018] S2. Control the receiving assembly to sleeved the valve bag on the filling nozzle;

[0019] S3. Control the feeding assembly to convey the calcium carbonate into the filling nozzle and convey it into the valve bag through the filling nozzle;

[0020] S4. Control the receiving assembly to send the valve bag to the sealing assembly with the opening facing upward, and control the sealing assembly to strike the opening of the valve bag, so that the calcium carbonate attached to the inner wall of the opening is shaken off and falls into the valve bag, keeping the opening of the valve bag clean;

[0021] S5. Control the sealing assembly to thermally seal the opening of the valve bag;

[0022] S6. After the thermal sealing is completed, control the sealing assembly to send the valve bag to the conveyor belt, and convey the valve bag through the conveyor belt;

[0023] S7. Repeating steps S2 - S6 can continuously fill the calcium carbonate into the bag.

[0024] Beneficial effects

[0025] Compared with the prior art, the technical solution of the present invention has the following advantages:

[0026] 1. The present invention realizes the automatic sleeving of the valve bag on the filling nozzle by setting a rotatable feeding bin, which is controlled by a suction cup and a fifth electric push rod to open the opening of the valve bag, and then rotating the feeding bin to move the opening of the valve bag to the position of the filling nozzle, thus eliminating the need for manual bag opening and sleeving, reducing labor consumption, and minimizing the harm of dust to workers.

[0027] 2. By setting an air duct, the present invention enables the air in the bag to flow into the waste chamber through the air duct during the filling process, and at the same time, the dust flowing out with the air also enters the waste chamber, preventing it from spreading to the outside and reducing dust pollution.

[0028] 3. By setting a rotatable cross plate, after the filling is completed, the present invention controls the pressing plate to clamp the valve bag filled with calcium carbonate, and then drives the valve bag to rotate together with the cross plate. After rotation, the opening of the valve bag is set upward, so that the calcium carbonate at the opening of the valve bag slides into the valve bag, avoiding a large amount of calcium carbonate residue during heat sealing at the bag mouth and preventing the heat sealing from failing.

[0029] 4. By setting a knocking plate on the sealing component, and through the cooperation of the corrugated groove and the protrusion, together with the action of the second torsion spring, during the process of the seventh electric push rod controlling the combination of the left hot pressing plate and the right hot pressing plate, the knocking plate swings continuously, causing the left end of the knocking plate to continuously knock the opening of the valve bag, so that the calcium carbonate adhered to the inner wall of the opening of the valve bag falls into the valve bag under the vibration, keeping the opening of the valve bag clean, and thus enabling reliable heat sealing.

[0030] 5. By setting a convex block with an inclined surface on the sealing component and a rotatable right vertical side plate, during heat sealing, the right vertical side plate is placed at the bottom of the valve bag. When heat sealing is required, the sixth electric push rod controls the mounting plate to descend, causing the left hot pressing plate and the right hot pressing plate to descend to the opening of the valve bag, and at the same time driving the convex block to descend. Due to the action of the inclined surface, the slider overcomes the contraction of the first spring, enabling the convex block to cross over the right vertical side plate and come to the lower side of the right vertical side plate. After the heat sealing is completed, the sixth electric push rod drives the mounting plate to rise. At this time, the convex block rises accordingly and will push the right vertical side plate to rotate, pushing the valve bag placed on the side plate to the side, causing it to roll onto the conveyor belt, avoiding the valve bag from being impacted and causing leakage.

[0043] This embodiment also provides a method for packaging calcium carbonate with the above calcium carbonate production packaging system, including the following steps:

[0044] S1. Place the calcium carbonate powder finished product in the feeding assembly and place the valve pocket in the receiving assembly;

[0045] S2. Control the receiving assembly to sleeved the valve pocket on the filling nozzle 12;

[0046] S3. Control the feeding assembly to convey calcium carbonate into the filling nozzle 12 and convey it into the valve pocket through the filling nozzle 12;

[0047] S4. Control the receiving assembly to send the valve pocket to the sealing assembly with the opening facing upward, and control the sealing assembly to knock the opening of the valve pocket, so that the calcium carbonate attached to the inner wall of the opening is shaken off and falls into the valve pocket, keeping the opening of the valve pocket clean;

[0048] S5. Control the sealing component to perform heat-sealing on the opening of the valve bag.

[0049] S6. After the heat-sealing is completed, control the sealing component to send the valve bag to the conveyor belt 5, and convey the valve bag through the conveyor belt 5.

[0050] S7. Repeating steps S2 - S6 can continuously fill calcium carbonate into the bag.

[0051] In the above S1 of this embodiment, when placing the valve bag into the receiving component, control the second motor 37 to rotate, drive the feeding bin 31 to rotate, make its opening face upward, control the fifth electric push rod 34 to contract, drive the turning plate 3a to rotate through the turning rod 35, so that it does not block the insertion of the valve bag 6, control the fourth electric push rod 33 to extend, drive the moving plate 32 to descend, place the valve bag 6 into the feeding bin 31, make the opening side of the valve bag 6 be placed on the side where the suction cup 36 is located, and place the folded edge side of the opening of the valve bag 6 upward, and at the same time make the opening direction of the valve bag 6 face the filling nozzle 12, then control the fifth electric push rod 34 to extend, drive the turning plate 3a to turn over, so that the suction cup 36 buckles on the valve bag 6, control the fourth electric push rod 33 to contract, push the moving plate 32 to move upward, clamp the valve bag 6 in the feeding bin 31, control the second motor 37 to drive the feeding bin 31 to rotate, so that the side where the suction cup 36 is located faces downward (as Figure 2 shown), and the feeding is completed.

[0052] In the above S2 of this embodiment, when sleeving the valve bag on the filling nozzle 12, control the vacuum pump to evacuate the inside of the suction cup 36, so that the suction cup 36 adsorbs the folded edge of the opening of the valve bag 6, control the fifth electric push rod 34 to contract, drive the turning plate 3a to turn over, so that the suction cup 36 rotates 90°, make the folded edge of the opening of the valve bag 6 unfold and the opening be opened, control the second motor 37 to rotate, make the feeding bin 31 rotate, align the opened opening of the valve bag 6 with the filling nozzle 12 (as Figure 3 shown), control the first electric push rod 18 to contract, drive the sliding plate 21 to move leftward. Since the feeding bin 31 is rotatably arranged on the sliding plate 21, the opening of the valve bag 6 is sleeved on the filling nozzle 12. When the valve bag 6 moves in place, control the first electric push rod 18 to stop, control to stop evacuating the inside of the suction cup 36, control the fourth electric push rod 33 to extend slightly, so that the valve bag 6 is loosened, control the second motor 37 to rotate back, so that the valve bag 6 sleeved on the filling nozzle 12 is pulled out of the feeding bin 31, control the fifth electric push rod 34 to extend, drive the turning plate 3a to rotate back, buckle the valve bag 6 in the feeding bin 31 to prevent it from falling, the fourth electric push rod 33 contracts, clamp the valve bag 6 again, and when the feeding bin 31 rotates back to the Figure 2 shown position, the sleeving of the valve bag 6 is completed.

[0053] In step S3 of this embodiment, when filling the valve bag, the first cylinder 17 is controlled to extend, so that the pressing block 17a at its free end presses against the filling nozzle 12, clamping the valve bag on the filling nozzle 12 to prevent it from falling off. The first motor 16 is controlled to drive the discharge screw 15 to rotate. Driven by the discharge screw 15, calcium carbonate is conveyed into the filling nozzle 12 and then conveyed into the valve bag 6 through the filling nozzle 12. During the filling process, the air in the valve bag 6 enters the waste chamber 13 through the air duct 14, and at the same time, the dust flowing out along with the air also enters the waste chamber 13 for collection. When a certain amount of calcium carbonate is filled, the first motor 16 is stopped to complete the filling.

[0054] In step S4 of this embodiment, when cleaning the opening of the valve bag, the second electric push rod 24 is controlled to extend, pushing the pressing plate 25 to move, clamping the valve bag 6 filled with calcium carbonate. The first cylinder 17 is controlled to contract to release the opening of the valve bag 6. The first electric push rod 18 is controlled to extend, separating the valve bag 6 from the filling nozzle 12. The third electric push rod 26 is controlled to extend, pushing the cross plate 22 to rotate until the right vertical side plate 23 is horizontally placed. At this time, the opening of the valve bag 6 faces upward, so that the calcium carbonate in the opening falls into the valve bag 6 to prevent it from accumulating at the opening. At this time, the opening of the valve bag 6 is directly below the left hot pressing plate 442 and the right hot pressing plate 441. The sixth electric push rod 41 is controlled to contract, driving the mounting plate 42 to descend, so that the left hot pressing plate 442 and the right hot pressing plate 441 descend to both sides of the opening of the valve bag 6. At the same time, due to the action of the inclined plane, the convex block 47 contracts inward against the first spring 48 under the push of the right vertical side plate 23 and moves past the right vertical side plate 23 to the lower part of the right vertical side plate 23. The seventh electric push rod 43 is controlled to contract, driving the left hot pressing plate 442 to move towards the right hot pressing plate 441, and at the same time driving the linkage block 45 to move to the right. Due to the cooperation between the protrusion 461 and the corrugated groove 4b on the linkage block 45, and under the action of the second torsion spring 462, the knocking plate 46 keeps swinging, so that the left head of the knocking plate 46 continuously knocks on the opening of the valve bag 6, shaking off the calcium carbonate attached to the inner wall of the opening and falling into the valve bag 6, keeping the opening of the valve bag 6 clean. When the corrugated groove 4b completely moves to the right side of the protrusion 461, the seventh electric push rod 43 stops. At this time, the left hot pressing plate 442 and the right hot pressing plate 441 have not been merged yet, and the cleaning of the opening of the valve bag 6 is completed.

[0055] In step S5 of this embodiment, when heat-sealing the opening of the valve bag, the left hot pressing plate 442 and the right hot pressing plate 441 are powered on for heating, and then the seventh electric push rod 43 is controlled to continue to contract, so that the left hot pressing plate 442 and the right hot pressing plate 441 are merged for heat-sealing. Then the seventh electric push rod 43 is controlled to extend, separating the left hot pressing plate 442 and the right hot pressing plate 441 to complete the heat-sealing.

[0056] In step S6 of this embodiment, when the valve bag is sent to the conveyor belt 5, the second electric push rod 24 is controlled to contract, the valve bag 6 is released, the sixth electric push rod 41 is controlled to extend, driving the mounting plate 42 to rise, and then driving the convex block 47 to rise. Under the action of the convex block 47, the right vertical side plate 23 is pushed to rotate against the first torsion spring 231, and the valve bag is pushed to roll to one side of the right vertical side plate 23 and turn over, so that it rolls onto the conveyor belt 5. The valve bag is conveyed through the conveyor belt 5. At the same time, when the convex block 47 passes over the right vertical side plate 23, the right vertical side plate 23 is rotated back under the action of the first torsion spring 231 until the right vertical side plate 23 touches the limit stop rod 221 and resets.
