Description

Technical Field

[0001] This invention belongs to the field of solventless laminating machines, and particularly relates to a feeding mechanism for solventless laminating machines. Background Technology

[0002] Sodium-based bentonite waterproofing blanket (GCL) is a new type of waterproof and seepage-proof material composed of natural sodium-based bentonite and geotextile (or geomembrane). It utilizes the property of bentonite to expand when it comes into contact with water to form a dense waterproof layer, and is widely used in seepage prevention projects such as landfills, underground engineering, and artificial lakes.

[0003] Sodium-based bentonite waterproof blankets are typically made of three composite materials: an upper layer of non-woven geotextile, a middle layer of sodium-based bentonite, and a lower layer of woven geotextile or geomembrane; they are manufactured using an adhesive bonding composite process.

[0004] A solvent-free laminating machine is a device that uses solvent-free adhesives to bond two or more substrates together; it is also known as a reactive laminating machine. It features environmental friendliness, high efficiency, and hygiene, and is widely used in the food, pharmaceutical, and packaging industries.

[0005] However, existing solventless laminating machines are not suitable for producing sodium-based bentonite waterproof blankets. This is because the substrates of solventless laminating machines are mostly rolls of plastic film, metal foil, non-woven fabric, and paper, while the substrates required for producing sodium-based bentonite waterproof blankets contain sodium-based bentonite. Existing solventless laminating machines cannot feed sodium-based bentonite. Therefore, a feeding mechanism for a solventless laminating machine specifically designed for the production of sodium-based bentonite waterproof blankets is needed. Summary of the Invention

[0006] The purpose of this invention is to provide a feeding mechanism for a solventless laminating machine, which aims to solve the technical problem that existing solventless laminating machines cannot feed sodium-based bentonite.

[0007] The present invention is implemented as follows: a feeding mechanism for a solventless laminating machine includes a frame, which is installed on one side of the solventless laminating machine. From left to right, a first mounting mechanism, a sodium-based bentonite feeding mechanism, and a second mounting mechanism are installed on the frame. The first mounting mechanism is used to place raw materials, such as nonwoven geotextile rolls. A guide roller is also rotatably mounted on the frame. One end of the nonwoven geotextile roll passes over the guide roller from the top and is horizontally mounted on the solventless laminating machine. The sodium-based bentonite feeding mechanism contains sodium-based bentonite, and the sodium-based bentonite feeding mechanism is used to evenly lay sodium-based bentonite on the non-woven geotextile. A gluing mechanism is also provided between the first installation mechanism and the sodium-based bentonite feeding mechanism. The gluing mechanism applies glue to the surface of the non-woven geotextile so that the sodium-based bentonite can adhere to the non-woven geotextile. The second installation mechanism is used to place another material, such as woven geotextile or geomembrane.

[0008] Further technical solution: The first installation mechanism includes two guide light rods fixedly installed on the frame. A fixed plate and a movable plate are installed on the two guide light rods. The fixed plate is fixedly installed, and the movable plate is slidably installed. A drive plug is rotatably installed on the side of the fixed plate near the movable plate. A first reduction motor is fixedly installed on the other side of the fixed plate. The output end of the first reduction motor is fixedly connected to one end of the drive plug. A limit plug is rotatably installed on the side of the movable plate near the fixed plate. An adjustment motor is also installed on the frame. The output shaft of the adjustment motor is fixedly connected to a screw, and one end of the screw is threadedly connected to the movable plate. The structure of the second installation mechanism is the same as that of the first installation mechanism.

[0009] Further technical solution: The sodium-based bentonite feeding mechanism includes a dropping mechanism and a spreading mechanism; The material feeding mechanism is used to sprinkle sodium-based bentonite onto the surface of the nonwoven geotextile. The material spreading mechanism is installed on the side of the material dropping mechanism opposite to the first installation mechanism. The material spreading mechanism is used to evenly spread sodium-based bentonite on the surface of the nonwoven geotextile.

[0010] Further technical solution: The material feeding mechanism includes a hopper fixedly installed on the frame, the hopper storing sodium-based bentonite, a material spreading assembly installed at the bottom of the hopper, the material spreading assembly being used to sprinkle sodium-based bentonite onto non-woven geotextile, and multiple vibration motors installed on the side of the hopper.

[0011] Further technical solution: The fabric assembly includes a discharge box slidably installed at the bottom of the hopper, a return spring is connected between the discharge box and the hopper, two discharge rollers are rotatably installed inside the discharge box, and multiple corresponding discharge slots are opened on the two discharge rollers. The bottom of the discharge box is provided with a discharge port that communicates with all the discharge slots. A transmission pair, which is a gear pair, is connected between the two ends of the discharge rollers extending out of the discharge box. A third servo motor is fixedly installed on the side of the discharge box. The output shaft of the third servo motor is fixedly connected to the end of one discharge roller extending out of the discharge box. The hopper has a movable slot adapted to the discharge roller. The length of the movable slot is greater than the diameter of the discharge roller, thereby allowing the discharge roller to move relative to the hopper; In order to discharge all the material in the hopper, the discharge box is provided with a ramp at one end of the hopper, and the bottom end of the ramp extends to the surface of the discharge roller; To prevent sodium bentonite from adhering to the inner wall of the discharge trough and thus reducing the amount of raw material in a certain section, multiple scrapers are fixedly connected to the discharge box. One end of each scraper contacts the discharge trough. When the discharge roller rotates, the scraper can scrape the sodium bentonite in the discharge trough, ensuring uniform material discharge.

[0012] Further technical solution: The feeding mechanism also includes a filtering mechanism, the filtering mechanism includes a filter plate fixedly installed in the hopper, and the hopper frame is provided with a number of evenly distributed filter holes, and a dispersing mechanism is installed inside each filter hole; The dispersing mechanism includes a spherical ring frame fixedly installed inside the filter holes. The spherical ring frame has a ball joint inside the ball joint. A crushing rod is fixedly connected to the side of the ball joint. A shearing plate is slidably installed on the top of the filter plate. The shearing plate has several discharge holes adapted to the filter holes. One end of the crushing rod passes through the discharge holes. To accelerate the feeding of sodium bentonite, each feeding hole has a chamfer at the top. Larger clumps of sodium bentonite will fall smoothly into the feeding hole. When the shear plate and the filter plate move relative to each other, the crushing rod will collide with the clumps of sodium bentonite and break them up. Then, smaller clumps of sodium bentonite will fall along the gap between the filter hole and the spherical ring frame, while larger clumps of sodium bentonite will get stuck between the shear plate and the filter plate. As the shear plate moves, the sodium bentonite clumps are sheared into small pieces or directly broken up by the shear plate. The broken-up sodium bentonite will fall again, thus continuously breaking up clumps and allowing sodium bentonite to fall continuously. To drive the shearing plate to reciprocate, the filtering mechanism also includes an extension plate, which is fixedly connected to the side of the shearing plate. One end of the extension plate extends out of the hopper, and a second servo motor is fixedly installed on the hopper. The output shaft of the second servo motor is fixedly connected to a drive disk, and a lever is fixedly connected to the drive disk at an eccentric position near the side of the extension plate. A sliding groove is provided on the side of the extension plate, and one end of the lever is slidably installed inside the sliding groove.

[0013] Further technical solution: The material spreading mechanism includes two fixed frames fixedly installed on the frame, two sliding rods slidably installed between the two fixed frames, several equally spaced scraper plates fixedly connected to the bottom of each of the two sliding rods, a crossbeam fixedly connected between the two fixed frames, a gear rotatably installed on the crossbeam, and racks fixedly installed on the opposite sides of the two sliding rods, with each rack meshing with the gear. A first servo motor is fixedly mounted on a fixed frame. The output shaft of the first servo motor is fixedly connected to a reciprocating lead screw, and the reciprocating lead screw is threadedly connected to a sliding rod.

[0014] A further technical solution: A pre-compression assembly is also installed on the frame. The pre-compression assembly is installed between the material spreading mechanism and the second installation mechanism. The pre-compression assembly includes a rolling roller rotatably mounted on the frame. A second reduction motor is fixedly installed on the frame, and one end of the second reduction motor is fixedly connected to one end of the rolling roller.

[0015] Further technical solution: A support assembly is also installed on the frame, the support assembly includes two drive rollers, both of which are rotatably mounted on the frame, and a conveyor belt is connected between the two drive rollers. The material feeding mechanism, the material spreading mechanism, and the pre-compression assembly are all located above the conveyor belt. A third reduction motor is fixedly installed on the frame, and the output shaft of the third reduction motor is fixedly connected to one end of a drive roller. A support plate is also fixedly connected to the frame, and the support plate is located below the top layer conveyor belt.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. The present invention, by setting a sodium-based bentonite feeding mechanism between the first and second installation mechanisms, allows sodium-based bentonite to be laid on the first raw material and then pressed with the second raw material. This enables the existing solventless laminating machine to be used to produce sodium-based bentonite waterproof blankets. Furthermore, when the sodium-based bentonite feeding mechanism is not used and only the first and second installation mechanisms are used for feeding, the solventless laminating machine can produce other roll products, thus broadening the application range of the solventless laminating machine. 2. In this invention, by setting a material distribution assembly that is slidably installed at the bottom of the hopper, sodium-based bentonite can be smoothly discharged under the vibration of the third servo motor itself. Furthermore, by using a discharge roller with several equally spaced discharge troughs to assist in the discharge, sodium-based bentonite can form multiple separate sodium-based bentonite strips on the non-woven geotextile. Then, the material spreading mechanism evenly spreads the sodium-based bentonite strips, thereby making the distribution of sodium-based bentonite on the non-woven geotextile more uniform and improving the quality of the produced sodium-based bentonite waterproof blanket. 3. In this invention, by setting up a filtration mechanism, when sodium bentonite is discharged, the reciprocating shearing plate will shear the clumps of sodium bentonite. At the same time, the crushing rod will also break up the clumps of sodium bentonite, allowing the sodium bentonite to fall smoothly through the gap between the filter holes and the spherical ring frame. The unbroken clumps of sodium bentonite will remain stuck above the shearing plate until they are broken up, thus avoiding the reduction in the uniformity of sodium bentonite laying caused by clumping.

[0030] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0031] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0032] like Figures 1-12 As shown, a feeding mechanism for a solventless laminating machine provided by the present invention includes a frame 1, which is installed on one side of the solventless laminating machine. From left to right, a first mounting mechanism 9, a sodium-based bentonite feeding mechanism, and a second mounting mechanism 7 are installed on the frame 1. The first mounting mechanism 9 is used to place raw materials, such as non-woven geotextile rolls. A guide roller 2 is also rotatably mounted on the frame 1. One end of the non-woven geotextile roll passes over the guide roller 2 from the top and is horizontally mounted on the solventless composite machine. The sodium-based bentonite feeding mechanism contains sodium-based bentonite, and the sodium-based bentonite feeding mechanism is used to evenly lay sodium-based bentonite on the non-woven geotextile. A gluing mechanism is also provided between the first installation mechanism 9 and the sodium bentonite feeding mechanism. The gluing mechanism applies glue to the surface of the nonwoven geotextile so that the sodium bentonite can adhere to the nonwoven geotextile. The second installation mechanism 7 is used to place another material, such as woven geotextile or geomembrane. In this embodiment, a geomembrane is used. One end of the geomembrane is covered on the sodium bentonite on the surface of the nonwoven geotextile, and then they are passed together through the pressing component 8 on the solventless composite machine. The pressing component 8 is existing technology and will not be described in detail here. After being pressed by the pressing component 8, the nonwoven geotextile, sodium bentonite and geomembrane are bonded together to form a sodium bentonite waterproof blanket, which is then wound up by the winding mechanism on the solventless composite machine to form the final product. Alternatively, an adhesive applicator can be installed on the side of the second installation mechanism 7 to apply adhesive to the geomembrane, making the nonwoven geotextile, sodium bentonite and geomembrane bond more firmly. When producing other roll materials, the sodium-based bentonite feeding mechanism can be omitted, and only the first installation mechanism 9 and the second installation mechanism 7 can be used for feeding, thereby enabling the production of other products. The solventless laminating machine with this feeding mechanism can produce sodium-based bentonite waterproof blankets without affecting the production of other roll materials, thus solving the problem that the existing solventless laminating machine is not suitable for producing sodium-based bentonite waterproof blankets.

[0033] The present invention provides a feeding mechanism for a solventless laminating machine. In this embodiment, the first mounting mechanism 9 includes two guide rods 94 fixedly mounted on the frame 1. A fixed plate 93 and a movable plate 96 are mounted on the two guide rods 94. The fixed plate 93 is fixedly mounted, and the movable plate 96 is slidably mounted. A drive rod 92 is rotatably mounted on the side of the fixed plate 93 near the movable plate 96. A first reduction motor 91 is fixedly mounted on the other side of the fixed plate 93. The output end of the first reduction motor 91 is fixedly connected to one end of the drive rod 92. A limit rod 95 is rotatably mounted on the side of the movable plate 96 near the fixed plate 93. An adjustment motor 98 is also installed on the frame 1. The output shaft of the adjustment motor 98 is fixedly connected to a screw 97, and one end of the screw 97 is threadedly connected to the movable plate 96.

[0034] When installing the nonwoven geotextile roll, first move the movable plate 96 to the side so that the distance between the drive rod 92 and the limiting rod 95 is sufficient to accommodate the nonwoven geotextile roll. Then, insert one end of the nonwoven geotextile roll into the drive rod 92, and then align the center of the other end of the nonwoven geotextile roll with the limiting rod 95. Next, start the adjusting motor 98, which drives the screw 97 to rotate. The screw 97 drives the movable plate 96 to move, so that the movable plate 96 drives the limiting rod 95 to be inserted into the end of the nonwoven geotextile roll, thus completing the installation. When feeding the material, simply start the first reduction motor 91, and the first reduction motor 91 will drive the non-woven geotextile roll to rotate slowly through the drive rod 92.

[0035] Since the structures of nonwoven geotextile rolls and geomembrane rolls are similar, the structure of the second installation mechanism 7 can be the same as that of the first installation mechanism 9.

[0036] The present invention provides a feeding mechanism for a solventless laminating machine. In this embodiment, the sodium-based bentonite feeding mechanism includes a dropping mechanism 3 and a spreading mechanism 4. The material feeding mechanism 3 is used to sprinkle sodium-based bentonite onto the surface of the non-woven geotextile. The material spreading mechanism 4 is installed on the side of the material dropping mechanism 3 facing away from the first installation mechanism 9. The material spreading mechanism 4 is used to spread sodium-based bentonite evenly on the surface of the non-woven geotextile.

[0037] The present invention provides a feeding mechanism for a solventless composite machine. In this embodiment, the feeding mechanism 3 includes a hopper 31 fixedly installed on the frame 1. The hopper 31 stores sodium bentonite. A fabric spreading assembly 34 is installed at the bottom of the hopper 31. The fabric spreading assembly 34 is used to sprinkle sodium bentonite onto the nonwoven geotextile. Multiple vibration motors 32 are installed on the side of the hopper 31.

[0038] The present invention provides a feeding mechanism for a solventless laminating machine. In this embodiment, the fabric assembly 34 includes a discharge box 341 slidably installed at the bottom of the hopper 31. A return spring 342 is connected between the discharge box 341 and the hopper 31. Two discharge rollers 344 are rotatably installed inside the discharge box 341. Each of the two discharge rollers 344 has a plurality of corresponding discharge slots 346. The bottom of the discharge box 341 has a discharge port 347 that communicates with all the discharge slots 346. A transmission pair 343 is connected between the two discharge rollers 344 extending out of the discharge box 341. The transmission pair 343 is a gear pair 47. A third servo motor 349 is fixedly installed on the side of the discharge box 341. The output shaft of the third servo motor 349 is fixedly connected to the end of one discharge roller 344 extending out of the discharge box 341. The hopper 31 has a movable slot 3410 adapted to the discharge roller 344. The length of the movable slot 3410 is greater than the diameter of the discharge roller 344, so that the discharge roller 344 can move relative to the hopper 31; In order to discharge all the material in the hopper 31, the discharge box 341 is provided with a ramp 348 at one end of the hopper 31, and the bottom end of the ramp 348 extends to the surface of the discharge roller 344. To prevent sodium bentonite from adhering to the inner wall of the discharge trough 346 and thus reducing the amount of raw material in a certain section, a plurality of scrapers 345 are fixedly connected to the discharge box 341. One end of the scraper 345 contacts the discharge trough 346. When the discharge roller 344 rotates, the scraper 345 can scrape the sodium bentonite in the discharge trough 346 to ensure uniform material discharge.

[0039] Specifically, the third servo motor 349 is started, which drives the two discharge rollers 344 to rotate in opposite directions. Relying on the friction of the discharge trough 346, the sodium-based bentonite in the hopper 31 is brought to the bottom of the discharge roller 344. Under the action of gravity, the sodium-based bentonite falls onto the non-woven geotextile. Since there are gaps between the multiple discharge troughs 346, the sodium-based bentonite forms multiple separate sodium-based bentonite strips on the non-woven geotextile. Then the spreading mechanism 4 spreads the sodium-based bentonite strips evenly. In addition, it is worth mentioning that since the third servo motor 349 will vibrate during operation, under the action of the reset spring 342, the third servo motor 349 will drive the discharge box 341 to vibrate up and down. The discharge box 341 will impact the sodium bentonite in the hopper 31 through the discharge roller 344, breaking up the sodium bentonite and preventing it from clumping. Under the action of inertia, the sodium bentonite will be dropped more evenly.

[0040] The present invention provides a feeding mechanism for a solventless composite machine. Since sodium bentonite has weak fluidity and is prone to adhesion and clumping, which affects the discharge effect of sodium bentonite, in this embodiment, the feeding mechanism 3 further includes a filtering mechanism 33. The filtering mechanism 33 includes a filter plate 331 fixedly installed in the hopper 31. The hopper 31 frame 1 is provided with a plurality of evenly distributed filter holes 332. Each filter hole 332 is equipped with a dispersing mechanism inside. The dispersing mechanism includes a spherical ring frame 333 fixedly installed inside the filter hole 332. The spherical ring frame 333 has a ball joint 334 inside. A crushing rod 335 is fixedly connected to the side of the ball joint 334. A shearing plate 336 is slidably installed on the top of the filter plate 331. The shearing plate 336 has a plurality of discharge holes 337 adapted to the filter hole 332. One end of the crushing rod 335 passes through the discharge hole 337. To accelerate the discharge of sodium bentonite, each discharge hole 337 has a chamfered top. Larger clumps of sodium bentonite will fall smoothly into the discharge hole 337. When the shear plate 336 and the filter plate 331 move relative to each other, the crushing rod 335 will collide with the clumps of sodium bentonite and break them up. Smaller clumps of sodium bentonite will fall along the gap between the filter hole 332 and the spherical ring frame 333, while larger clumps of sodium bentonite will get stuck between the shear plate 336 and the filter plate 331. As the shear plate 336 moves, the sodium bentonite clumps are sheared into small pieces or directly broken up by the shear plate 336. The broken-up sodium bentonite will fall again, thus continuously breaking up clumps and allowing sodium bentonite to fall continuously. To drive the shear plate 336 to reciprocate, the filtering mechanism 33 also includes an extension plate 3310. The extension plate 3310 is fixedly connected to the side of the shear plate 336. One end of the extension plate 3310 extends out of the hopper 31. A second servo motor 3312 is fixedly installed on the hopper 31. The output shaft of the second servo motor 3312 is fixedly connected to a drive disk 3311. A lever 338 is fixedly connected to the drive disk 3311 at an eccentric position near the side of the extension plate 3310. A sliding groove 339 is provided on the side of the extension plate 3310. One end of the lever 338 is slidably installed inside the sliding groove 339.

[0041] Specifically, the second servo motor 3312 rotates continuously. The second servo motor 3312 drives the lever 338 to rotate eccentrically through the drive disk 3311. The lever 338 drives the extension plate 3310 to reciprocate. The extension plate 3310 drives the shearing plate 336 to reciprocate. The sodium-based bentonite falling into the discharge hole 337 will drive the crushing rod 335 to move. When the crushing rod 335 is blocked by the filter plate 331, the sodium-based bentonite and the crushing rod 335 move relative to each other, thereby breaking up the clumps of sodium-based bentonite. This allows the sodium-based bentonite to fall smoothly through the gap between the filter hole 332 and the spherical ring frame 333. The unbroken clumps of sodium-based bentonite will remain stuck above the shearing plate 336 until they are broken up, thus avoiding a decrease in the uniformity of sodium-based bentonite laying due to clumping.

[0042] The present invention provides a feeding mechanism for a solventless laminating machine. In this embodiment, the feeding mechanism 4 includes two fixed frames 44 fixedly installed on the frame 1. Two sliding rods 43 are slidably installed between the two fixed frames 44. Several equally spaced scraper plates 45 are fixedly connected to the bottom of each of the two sliding rods 43. A crossbeam 48 is fixedly connected between the two fixed frames 44. A gear 47 is rotatably installed on the crossbeam 48. A rack 46 is fixedly installed on the opposite sides of each of the two sliding rods 43. Both racks 46 are meshed with the gear 47. A first servo motor 41 is fixedly mounted on a fixed bracket 44. The output shaft of the first servo motor 41 is fixedly connected to a reciprocating lead screw 42. The reciprocating lead screw 42 is threadedly connected to a sliding rod 43.

[0043] Specifically, the first servo motor 41 drives a sliding rod 43 to reciprocate through the reciprocating screw 42. The sliding rod 43 drives the gear 47 to rotate through the rack 46. The gear 47 drives another rack 46 and another sliding rod 43 to move in opposite directions. The two sliding rods 43 drive the scraper 45 to scrape the sodium bentonite strip flat, thereby making the fabric more uniform.

[0044] The present invention provides a feeding mechanism for a solventless composite machine. Because the laid sodium bentonite has a certain thickness, only the sodium bentonite in contact with the solventless adhesive on the nonwoven geotextile will be adhered. The other sodium bentonite is in a moving state. When the nonwoven geotextile is impacted or vibrated, the sodium bentonite will scatter in all directions, reducing the thickness of the sodium bentonite in some areas and affecting the quality of the waterproof blanket. Therefore, in this embodiment, a pre-compression assembly 5 is also installed on the frame 1. The pre-compression assembly 5 is installed between the laying mechanism 4 and the second installation mechanism 7. The pre-compression assembly 5 includes a rolling roller 51 rotatably installed on the frame 1. A second reduction motor 52 is fixedly installed on the frame 1, and one end of the second reduction motor 52 is fixedly connected to one end of the rolling roller 51.

[0045] Specifically, the rotation speed of the roller 51 is the same as the movement speed of the nonwoven geotextile. When the nonwoven geotextile and sodium bentonite pass under the roller 51, the roller 51 will squeeze the sodium bentonite to initially compact it and prevent it from scattering around. In addition, the distance from the bottom of the roller 51 to the surface of the nonwoven geotextile is slightly larger than the gap between the pressing components 8 on the solventless composite machine, so that the geomembrane and sodium bentonite can better adhere and improve the quality of the waterproof blanket.

[0046] The present invention provides a feeding mechanism for a solventless composite machine. Because the nonwoven geotextile is relatively soft, it undergoes slight deformation after being laid with sodium bentonite. When passing through the pre-compression assembly 5, the nonwoven geotextile is bent by the rolling roller 51 instead of being compacted by the sodium bentonite, significantly reducing the uniformity of the sodium bentonite. Therefore, in this embodiment, a support assembly 6 is also installed on the frame 1. The support assembly 6 includes two drive rollers 62, both rotatably mounted on the frame 1. A conveyor belt 63 is connected between the two drive rollers 62. The material dropping mechanism 3, the material laying mechanism 4, and the pre-compression assembly 5 are all located above the conveyor belt 63. A third reduction motor 61 is fixedly installed on the frame 1, and the output shaft of the third reduction motor 61 is fixedly connected to one end of a drive roller 62. A support plate 64 is also fixedly connected to the frame 1, located below the top layer conveyor belt 63.

[0047] Specifically, the movement speed of the conveyor belt 63 is the same as that of the nonwoven geotextile to avoid wear between the nonwoven geotextile and the conveyor belt 63, while the support plate 64 supports the nonwoven geotextile and sodium bentonite to prevent deformation of the nonwoven geotextile.

[0048] 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 within the protection scope of the present invention.

[0049] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity.
