Description

Technical Field

[0001] The present invention relates to the technical field of the production of emulsified granular ammonium nitrate fuel oil explosive, and in particular to a sealing device for bagged products on an emulsified granular ammonium nitrate fuel oil explosive production line. Background Art

[0002] In the production process of emulsified granular ammonium nitrate fuel oil explosive, the efficiency and safety of the production line are of crucial importance. At present, in the packaging link of bagged products on the emulsified granular ammonium nitrate fuel oil explosive production line, there are many problems to be solved in the stage from the completion of filling to the operation of the sewing machine.

[0003] When the filled packaging bag is conveyed and transitioned to the sewing machine, due to the lack of effective intervention measures in the conveying and transition gap between filling and the sewing machine, the material opening of the packaging bag is prone to interlacing. This not only causes raw material leakage and material waste, but also seriously affects the subsequent sewing operation of the sewing machine due to the residue of raw materials at the material opening. When the sewing machine is working, the residual raw materials may cause thread breakage, or the material opening of the packaging bag cannot be tightly sewn, resulting in looseness, and thus generating defective products, increasing the production cost and bringing great potential safety hazards to the transportation safety of the products.

[0004] When the material opening of the packaging bag enters the sewing head of the sewing machine, the existing guiding and shielding structure will cause wrinkles at the material opening. These wrinkles will be sewn by the sewing machine immediately to form a wrinkled bag mouth. Such a bag mouth is extremely prone to raw material leakage, and when the wrinkles are too thick, it will also cause jamming of the bag mouth of the sewing machine, resulting in thread breakage. Once such a situation occurs, it is necessary to stop the machine for maintenance, which not only reduces the production efficiency, but also increases the equipment maintenance cost, seriously affecting the production continuity of emulsified granular ammonium nitrate fuel oil explosive.

The bag mouth is opened by the material port adsorption and lifting assembly. Then, when the expansion rack 67 is in a vertical state, the double-axis cylinder 64 is started to drive the expansion pins 65 to expand to both sides to tighten the bag mouth. At this time, the adsorption force of the material port adsorption and lifting assembly is cancelled, and then the second self-locking torque motor 62 is started to drive the flipping rack 63 to flip. Subsequently, the flipping rack 63 drives the expansion rack 67 to flip, and the flip direction is towards the bottom of the feeding hopper 3, in a horizontal and upward state.

The support frame 201 can support the packaging bag conveyed to the lower vacuum adsorption plate 202. At the same time, the lower vacuum adsorption plate 202 adsorbs the bottom of the packaging bag mouth. Then, the cylinder 204 is started to drive the upper vacuum adsorption plate 205 to move downward to adsorb the upper part of the material port of the packaging bag. Then, the cylinder 204 is started to move upward to lift the packaging bag mouth upward through the upper vacuum adsorption plate 205 to open it. At this time, it is convenient for the vertically placed bag expanding rack 68 to tighten the lifted packaging bag. Subsequently, the adsorption force between the upper vacuum adsorption plate 205 and the lower vacuum adsorption plate 202 is disconnected, which is convenient for the expansion rack 67 to be driven by the flipping rack 63 to flip again, so that the expansion rack 67 drives the bag expanding rack 68 and the packaging bag on the bag expanding rack 68 to flip to the outside of the blanking expansion hopper 103, which is convenient for the blanking expansion hopper 103 to perform the tightening operation on the packaging bag mouth.

[0028] The material port guiding and sorting mechanism is arranged on one side of the bottom of the top plate 1 close to the second belt conveyor 5 and is used for removing wrinkles and vibrating and sorting the bag mouth of the packaging bag at the connection of the first belt conveyor 4 and the second belt conveyor 5. The material port guiding and sorting mechanism includes a suspension frame 52, a guiding plate 53, a connecting plate 521, a driving motor 522, a conveying frame 528, a rubber roller 529, a bag mouth flattening component and a bag mouth vibrating and impurity removing component. The top of the suspension frame 52 is fixedly installed with the top plate 1, and the bottom of the suspension frame 52 is fixedly installed with the top of the connecting plate 521. The conveying frame 528 is fixedly installed on one side of the connecting plate 521 close to each other. Six groups of rubber rollers 529 are arranged and are horizontally and rotationally distributed at equal distances inside the conveying frame 528. The top and bottom of the rubber roller 529 are rotationally matched with the conveying frame 528. The bottom pins of the six groups of rubber rollers 529 penetrate through the conveying frame 528 and are in transmission cooperation through a plurality of groups of interconnected synchronous wheels and synchronous belts. The driving motor 522 is fixedly installed at the center of the top of the connecting plate 521. The guiding plate 53 is fixedly installed on one side of the conveying frame 528 close to the first belt conveyor 4. The bag mouth flattening component is arranged on the connecting plate 521 and is used for driving the rubber roller 529 so that multiple groups of rubber rollers 529 are linked to guide and flatten the bag mouth of the packaging bag. The bag mouth vibrating and impurity removing component is arranged on the connecting plate 521 and is used for vibrating the bag mouth of the packaging bag inside the conveying frame 528 so that the raw material particles remaining on the inner wall fall into the bag. The two driving motors 522 are driven in opposite directions; When the packaging bag conveyed to the connection of the second belt conveyor 5 and the first belt conveyor 4 after filling passes through the guiding plate 53, it is initially guided by the guiding plate 53. Subsequently, the bag mouth of the packaging bag enters the conveying frame 528. The rubber rollers 529 in the conveying frame 528 are synchronously driven in multiple groups by the driving motor 522 in cooperation with the bag mouth flattening component, as Figure 11 shown. This method can ensure that the bag mouth of the packaging bag is in a flat state when it is about to enter the sewing position of the sewing machine 51, without stacking or wrinkling, avoiding work injuries that are likely to occur when manually sorting because it is close to the sewing machine. Moreover, the driving motor 522 cooperates with the bag mouth vibrating and impurity removing component to vibrate the bag mouth of the packaging bag inside the conveying frame 528 to remove the particles at the edge of the bag mouth, avoiding the influence of the particles on the work of the sewing machine 51.

[0029] The bag mouth flattening assembly includes a first gear 523, a first bevel gear 5221 and a second bevel gear 5222. The first gear 523 is fixedly installed at the output end of the drive motor 522. The first bevel gear 5221 is fixedly installed on the side of the output end of the drive motor 522 away from the first gear 523. The second bevel gear 5222 is fixedly installed on the rubber roller 529 on the side close to the first bevel gear 5221. The second bevel gear 5222 meshes with the first bevel gear 5221; After the drive motor 522 is started, it can drive the first bevel gear 5221 to rotate, and then drive the meshing second bevel gear 5222 to rotate through the first bevel gear 5221. Subsequently, drive one group of rubber rollers 529 to rotate through the second bevel gear 5222. Then, the rubber rollers 529 drive the remaining multiple groups of rubber rollers 529 to rotate synchronously through the synchronous belt and synchronous pulley, thereby flattening the bag mouth of the packaging bag.

[0030] The bag mouth vibration impurity removal assembly includes an installation groove 5211, a second gear 524, a percussion drive shaft 525, a cam 526, a stabilizing frame 527, a percussion tilting plate 5261, a limit shaft frame 5262, a tension spring 5263, a limit tube 5264, a spring 5265 and a plastic impact rod 5266. Four groups of installation grooves 5211 are provided. The installation grooves 5211 are symmetrically arranged on the top of the connecting plate 521 and are located above the gap between every two groups of rubber rollers 529. The limit shaft frame 5262 is fixedly installed at the bottom of the connecting plate 521 and is located below the installation groove 5211. The percussion tilting plate 5261 is rotatably installed inside the limit shaft frame 5262. Four groups of limit tubes 5264 are arranged longitudinally and equidistantly at the bottom of the mutually close sides of the percussion tilting plate 5261. The plastic impact rod 5266 is slidably installed inside the limit tube 5264. One end of the spring 5265 is fixedly installed with the plastic impact rod 5266, and the other end is fixedly installed with the inner wall of the limit tube 5264 close to the percussion tilting plate 5261. One end of the tension spring 5263 is fixedly installed with one side of the inner wall of the installation groove 5211, and the other end is fixedly installed with the percussion tilting plate 5261. The stabilizing frame 527 is fixedly installed on both sides of the top of the connecting plate 521. The percussion drive shaft 525 is rotatably installed inside the stabilizing frame 527. The number of cams 526 is the same as that of the percussion tilting plates 5261. The cams 526 are fixedly installed on the surface of the percussion drive shaft 525 and are used in cooperation with the percussion tilting plates 5261. The second gear 524 is fixedly installed on the surface of the percussion drive shaft 525 and meshes with the first gear 523; After the driving motor 522 is started, it can drive the first gear 523 to rotate, and then drive the second gear 524 meshing with it to rotate through the first gear 523, and then drive the knocking drive shaft 525 to rotate through the second gear 524, and then drive multiple groups of cams 526 to rotate synchronously through the knocking drive shaft 525, and then the knocking tilting plate 5261 is toggled. After the knocking tilting plate 5261 is toggled, it is limited by the limit shaft frame 5262, so that the knocking tilting plate 5261 is like a seesaw. When the top moves outward, the bottom will be pressed inward. In the process of pressing inward, the bottom of the knocking tilting plate 5261 will drive four groups of limit Tube 5264 simultaneously hits the opening of the packaging bag. When the limiting tube 5264 drives the plastic impact rod 5266 to hit the opening of the packaging bag, the impact buffering can be achieved through the spring 5265 to avoid rigid impact to damage the opening of the packaging bag, and the impact will cause the particles at the opening of the packaging bag to be vibrated back into the packaging bag, to avoid the situation where the gap becomes larger due to the particles. When the top of the knocking and tilting plate 5261 is pushed outward, the tension spring 5263 generates a pulling force. When the impact is completed, the tension of the tension spring 5263 is reset to drive the top of the knocking and tilting plate 5261 to approach the cam 526, so as to facilitate the knocking and tilting plate 5261 to perform another vibration and knocking operation.

[0031] A fixing rod 502 is fixedly installed on the top of both sides of the second belt conveyor 5, and a supporting plate 501 is fixedly installed on the top of the fixing rod 502. The supporting plate 501 is used to guide the waist of the packaging bag conveyed to the second belt conveyor 5; The fixing rod 502 can fix and support the supporting plate 501 , and the supporting plate 501 can centrally support the packaging bag conveyed to the top of the second belt conveyor 5 , thereby ensuring the processing stability of the bag sewing machine 51 .

[0032] Working principle: When the packaging operation starts, the packaging bag is transported to the lower vacuum adsorption plate 202 of the packaging bag expansion and flipping mechanism. Under the action of the material opening adsorption and lifting component, the bag opening of the packaging bag is opened, and the double-axis cylinder 64 drives the expansion pin 65 to expand and tighten the bag opening. Then the second self-locking torque motor 62 drives the flipping frame 63 to flip, and the packaging bag is put on the unloading expansion bucket 103 to complete the material receiving preparation; At this time, the bag mouth tightening mechanism starts to operate, and the first self-locking torque motor 105 drives the expansion drive gear 106 to rotate, driving the unloading expansion bucket 103 to expand outward, and cooperates with the fixed plate 102 to tighten the bag mouth of the bag, ensuring that the process of the upper hopper 3 filling the bag with material is stable and preventing material leakage; After the filling is completed, the first self-locking torque motor 105 drives in the reverse direction, the blanking expansion hopper 103 resets, the packaging bag drops onto the first belt conveyor 4, and the finished product stable transfer mechanism responds quickly. At the same time, the first belt conveyor 4 starts to drive the filled packaging bag at the top, and at the same time, the driving component is started to synchronously drive the screw sleeve 401 to move horizontally, making the packaging bag more stable during the horizontal movement. The screw sleeve 401 moves to both sides of the packaging bag under the action of the driving component. The material bag extrusion cylinder 405 and the material port extrusion cylinder 403 are started synchronously to support the packaging bag and make it in the central position of the conveyor. The material port extrusion cylinder 403 flattens the material port of the packaging bag, facilitating it to enter the material port guiding and sorting mechanism for processing. When the packaging bag is on the first belt conveyor 4, then the driving component drives the whole mechanism, and the packaging bag is smoothly conveyed to the connection between the first belt conveyor 4 and the second belt conveyor 5; When the packaging bag reaches the connection, the material port guiding and sorting mechanism immediately comes into play. The guiding plate 53 conducts preliminary guiding on the packaging bag, making its bag mouth enter the conveying frame 528. Inside the conveying frame 528, the bag mouth flattening component and the bag mouth vibration and impurity removal component work simultaneously. The rubber roller 529 flattens the bag mouth, and the knocking and tilting plate 5261 drives the plastic impact rod 5266 to vibrate the bag mouth to clean the residual particles at the bag mouth, preparing for the sewing operation. At the same time, the material port adsorption and lifting component continues to work, the bag mouth of the packaging bag is opened, and then the second self-locking torque motor 62 is started to drive the flipping frame 63 to flip to the opened bag mouth of the packaging bag. With the help of the bottom bucket structure of the bag expanding frame 68, the packaging bag is expanded and tensioned. During this process, since the screw sleeve 401 has moved to the connection between the first belt conveyor 4 and the second belt conveyor 5, the flipping bag expanding frame 68 will not be mechanically interfered at this time. At the same time, by reasonably using the step interval, the preliminary expansion operation of the packaging bag mouth is completed. Subsequently, before the screw sleeve 401 retreats to the middle position of the first belt conveyor 4, the second self-locking torque motor 62 is started again to drive the flipping frame 63 to flip to the blanking expansion hopper 103, and the previous operation is continued in a cycle to receive materials. After receiving the materials, the stepping motor 45 is started to complete the retraction operation of the screw sleeve 4 to move it to the material receiving position to support the filled packaging bag; Finally, the sorted packaging bag enters the second belt conveyor 5, and the 501 on both sides guides the waist of the packaging bag to ensure that its position is centered during the conveying process, facilitating the sewing machine 51 to sew the packaging bag and completing the entire packaging process; Next, the working parts of each mechanism will be introduced in detail: Packaging bag mouth expanding and flipping mechanism: The bag opening and flipping mechanism of the packaging bag adsorbs and flips the packaging bag so that it is under the feeding hopper 3 and ready to receive materials. The material port adsorption and lifting assembly works first. The support frame 201 supports the packaging bag fed from above to the lower vacuum adsorption plate 202. The lower vacuum adsorption plate 202 adsorbs the bottom of the packaging bag opening. Subsequently, the first cylinder 204 drives the upper vacuum adsorption plate 205 downward to adsorb the upper part of the packaging bag opening and then lift it upward to open the packaging bag opening. This design ensures that the packaging bag opening can be opened stably and reliably, avoiding the folding of the bag opening, facilitating the subsequent bag opening operation, and improving the stability and reliability of the operation; After the bag opening is opened, the expansion frame 67 is in a vertical state. The double-axis cylinder 64 is activated to drive the expansion pins 65 to expand to both sides to tension the packaging bag opening. Subsequently, the adsorption force of the material port adsorption and lifting assembly is cancelled. The second self-locking torque motor 62 drives the flipping frame 63 to flip, and then drives the expansion frame 67 and the bag expanding frame 68 to flip to the bottom of the feeding hopper 3, so that the packaging bag at the bottom of the bag expanding frame 68 is sleeved on the discharging expansion hopper 103. This process realizes the precise positioning of the packaging bag, ensures the stability of the packaging bag during the material receiving process, reduces the possibility of material spillage, and improves the accuracy and efficiency of filling; Packaging bag material port tightening mechanism: The packaging bag material port tightening mechanism expands and tightens the packaging bag opening flipped under the feeding hopper 3 for stable filling. As Figure 6 shown, the fixed frame 101 and the fixed plate 102 cooperate to limit the expansion of the discharging expansion hopper 103. The first self-locking torque motor 105 is activated to drive the expansion drive gear 106 to rotate through the output end. Since the two groups of expansion drive gears 106 are meshed with each other, they will drive the corresponding discharging expansion hopper 103 to expand outward. The special shape at the bottom of the discharging expansion hopper 103 cooperates with the fixed plate 102 to expand and tighten the packaging bag flipped to its outside, ensuring the stability of the packaging bag opening during filling; After filling is completed, the first self-locking torque motor 105 drives in the reverse direction, and the discharging expansion hoppers 103 approach and flip each other. The filled packaging bag falls on the first belt conveyor 4. This design ensures the stability of the filling process, reduces the risk of material leakage, and at the same time realizes the automatic discharging of the packaging bag after filling is completed, improving the production efficiency; Finished product stable transfer mechanism: The finished product stable transfer mechanism supports the packaging bag after loading, so that it moves smoothly to the connection point between the first belt conveyor device 4 and the second belt conveyor device 5. The screw sleeve 401 can be moved horizontally to both sides of the filled packaging bag under the action of the driving component. When the packaging bag falls, the material bag squeezing electric cylinder 405 and the material port squeezing electric cylinder 403 are started at the same time. The material port squeezing electric cylinder 403 drives the material port squeezing plate 404 to squeeze the bag mouth of the packaging bag to make it flat and prevent the material from spilling; the material bag squeezing electric cylinder 405 drives the material bag squeezing plate 406 to squeeze and support the waist of the packaging bag, so that the packaging bag is located in the center of the top of the first belt conveyor device 4. This design effectively avoids the packaging bag from tilting or shaking during the conveying process, ensures the stability of the conveying, and provides good conditions for subsequent processing procedures; After the material bag squeezing plate 406 and the material port squeezing plate 404 reach the limit position, the driving assembly starts to work, the stepping motor 45 starts, drives the screw rod 41 to rotate, the screw rod 41 drives the first sprocket 42 to rotate, the first sprocket 42 drives the second sprocket 44 to rotate through the chain 43, so that the screw rods 41 on both sides of the first belt conveyor 4 rotate synchronously, and the two screw sleeves 401 are synchronously driven laterally. The screw sleeves 401 drive the bag stabilizing frame 402, the material bag squeezing plate 406 and the material port squeezing plate 404 to move synchronously, and the packaging bag is supported and conveyed. This synchronous drive design ensures the stability and accuracy of the packaging bag during the conveying process, and improves the conveying efficiency; Feeding port guide finishing mechanism: The material opening guiding and arranging mechanism removes wrinkles and vibrates the bag opening at the junction of the first belt conveyor device 4 and the second belt conveyor device 5 to ensure the normal operation of the bag sewing machine 51. When the filled bag is conveyed to the junction of the second belt conveyor device 5 and the first belt conveyor device 4, the guide plate 53 preliminarily guides the bag, and then the bag opening of the bag enters the conveying frame 528. The bag opening leveling assembly starts to work, the driving motor 522 starts, drives the first gear 523 to rotate, the first gear 523 drives the second gear 524 meshing therewith to rotate, the second gear 524 drives the knocking drive shaft 525 to rotate, the knocking drive shaft 525 drives multiple groups of cams 526 to rotate synchronously, the cam 526 toggles the knocking tilting plate 5261, so that the knocking tilting plate 5261 moves like a seesaw, and the bottom drives the limiting tube 5264 and the plastic impact rod 5266 to hit the bag opening of the packaging bag, and the impact buffering is achieved by the spring 5265 to avoid damaging the bag opening of the packaging bag. This process causes the particles at the bag opening of the packaging bag to be vibrated back into the packaging bag, reducing the influence of the particles at the edge of the bag opening on the operation of the bag sewing machine 51 and improving the quality of the bag sewing; Meanwhile, the bag mouth flattening assembly works. The driving motor 522 drives the first bevel gear 5221 to rotate. The first bevel gear 5221 drives the engaged second bevel gear 5222 to rotate. The second bevel gear 5222 drives one group of rubber rollers 529 to rotate. The rubber rollers 529 drive the other rubber rollers 529 to rotate synchronously through the synchronous belt and synchronous pulley, and flatten the bag mouth of the packaging bag. This design effectively eliminates the wrinkles at the bag mouth of the packaging bag, ensures that the sewing machine 51 can smoothly perform the sewing work, and improves the aesthetics and sealing performance of sewing. Second belt conveyor guiding assembly: The fixed rods 502 at the top on both sides of the second belt conveyor 5 fixedly support the supporting plate 501. The supporting plate 501 guides the waist of the packaging bag conveyed onto the second belt conveyor 5, realizing the centered support of the packaging bag. This design ensures the processing stability of the sewing machine 51, reduces the sewing quality problems caused by the position deviation of the packaging bag, and improves the product qualification rate.
