Description

Technical Field

[0001] The present invention relates to the technical field of barrel coating packaging, and particularly to an intelligent packaging system for barreled fluids. Background Art

[0002] Coatings refer to a class of liquid or solid materials that can form a film on the surface of an object under certain conditions to provide protection, decoration, or other special functions (such as insulation, rust prevention, mildew prevention, heat resistance, etc.). Since most early coatings were mainly made from vegetable oils, they were also called paints. Now, synthetic resins have replaced vegetable oils, so they are called coatings. Coatings are not all in liquid form, and powder coatings are a major category of coating varieties.

[0003] After the coating production is completed, it usually needs to be packaged in barrels. The common intelligent packaging systems are as follows: First, the intelligent barrel separator separates empty barrels individually and conveys them along the conveyor belt at the bottom of the barrel. During the conveying process, labels are automatically pasted on the surface of the empty barrels. Secondly, when the empty barrel reaches below the corresponding filling machine, the coating automatically flows into the barrel. When the predetermined weight is reached, the filling machine automatically stops feeding and drives the barrel to move on the conveyor belt again. Finally, the barrel will be capped and crimped by the capping machine above the conveyor belt, and then the packaging is completed by the winding film machine. However, generally when the filling machine is filling, its discharge tube is mostly located at the center of the empty barrel for discharging the coating. When a large amount of coating needs to be filled individually, the continuously vertically discharged coating is likely to collide with the existing coating in the barrel, and then multiple coating bubbles may form and float on the surface of the coating. In an automated packaging system, the viscous bubbles may be ignored by the staff. Since the texture of general coatings is relatively viscous, these bubbles have a certain toughness and are not easily broken naturally. After packaging, it may reduce the quality of the coating during use. For this reason, we propose an intelligent packaging system for barreled fluids. Summary of the Invention

[0004] The purpose of the present invention is to provide an intelligent packaging system for barreled fluids to solve the problems raised in the above background art.

[0005] To achieve the above purpose, the present invention provides the following technical solution: An intelligent packaging system for barreled fluids, including a filling machine. One side of the filling machine is provided with a base. Above the base is provided a conveyor belt. Above the conveyor belt is provided a barrel for containing the coating. One side of the conveyor belt is provided with a labeling machine for pasting labels on the outer wall of the barrel. One side of the conveyor belt is also provided with a barrel separator for separating stacked barrels. One side of the conveyor belt is also provided with a capping machine for capping the port of the barrel. One side of the filling machine is provided with a discharge tube, and outside the discharge tube is provided a stirring assembly for stirring the bubbles in the barrel.

[0006] Preferably, the stirring assembly includes a first bevel gear located outside the discharge cylinder. A stirring rod is provided inside the first bevel gear. A square hole for the up-and-down sliding of the stirring rod is provided inside the first bevel gear. The width of the square hole is greater than the diameter of the stirring rod, which enables the stirring rod to have a certain buffering performance when moving up and down inside the first bevel gear.

[0007] Preferably, a driving assembly for stirring the air bubbles inside the barrel during filling is provided inside the discharge cylinder. The driving assembly includes a connecting plate. A spring is provided at the top of the connecting plate. One end of the spring is fixedly connected to the discharge cylinder. A connecting block is provided at the bottom of the connecting plate. An inner cylinder is provided at one end of the connecting block. The inner cylinder is located inside the discharge cylinder. The discharge cylinder includes a vertical groove for the sliding of the connecting block. A U-shaped rod is provided on one side of the connecting block. A rack is provided at one end of the U-shaped rod. Due to the special shape of the U-shaped rod itself, it will not collide with the second bevel gear below, and further enables the rack to smoothly enter the slot inside the cover body. A gear is provided on one side of the rack. A fixed shaft is provided inside the gear. A second bevel gear meshing with the first bevel gear is provided outside the fixed shaft. A fixed block is also provided outside the fixed shaft.

[0008] Preferably, a blocking block is provided outside the discharge cylinder. The stirring rod includes a spherical part. The blocking block includes an arc-shaped chute. The spherical part is located inside the arc-shaped chute of the blocking block. The stirring rod further includes a notch. The notch abuts against the bottom of the arc-shaped chute. By using the mutual cooperation of the stirring assembly and the driving assembly, the stirring rod can break the coating liquid that has been filled in the barrel, and at the same time, part of the coating liquid located in the center can be diffused to the periphery of the barrel, reducing the generation of air bubbles in the barrel while enhancing the uniformity of the coating in the barrel and improving the subsequent use quality of the coating.

[0009] Preferably, the bottom of the blocking block is shaped as a gradually descending arc surface, and the top inner wall of the arc-shaped chute always contacts the top surface of the spherical part.

[0010] Preferably, a cover body for shielding the opening part of the barrel is provided outside the discharge cylinder. The diameter of the cover body is greater than the diameter of the barrel. The cover body is located directly above the port of the barrel. During the continuous injection of the coating into the barrel, it can prevent part of the coating from splashing out due to collision, reducing the waste of the coating during the packaging process and also being beneficial to the protection of the packaging environment around the barrel.

[0011] Preferably, an arc-shaped groove for the sliding of the stirring rod is provided inside the cover body. A connecting piece is provided outside the stirring rod. An outer cylinder is provided at one end of the connecting piece. A scraping piece is provided at the bottom end of the outer cylinder.

[0012] Preferably, the side surface of the scraping blade is an inclined surface sloping downward. The scraping blade includes a protruding portion located on one side of the bottom end of the discharge cylinder. When the stirring rod slides inside the arc-shaped groove as the first bevel gear rotates, the stirring rod will also drive the connecting member and the outer cylinder to rotate outside the discharge cylinder. Thus, the scraping blade with an inclined side surface can scrape the paint that may adhere to the surface of the discharge cylinder and finally flow back into the barrel interior from the inclined surface of the scraping blade. Meanwhile, the protruding portion located at the bottom of the scraping blade can effectively wipe the paint at the port part of the discharge cylinder. Along with the secondary reset of the stirring rod, the scraping blade and the protruding portion will repeatedly clean the surface of the discharge cylinder to improve the utilization rate of the paint during the paint packaging process.

[0013] Preferably, a slot for inserting the rack is provided inside the cover body.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0015] 1. In the present invention, when the barrel reaches the central part of the discharge cylinder and automatic filling is carried out, the paint inside the discharge cylinder will resist the top surface of the inner cylinder inside it. Thus, the connecting blocks outside the inner cylinder will descend simultaneously. The descending connecting blocks will drive the U-shaped rod and the rack fixedly connected to it to descend simultaneously. During the descending process, due to the special shape of the U-shaped rod itself, it will not resist the second bevel gear below, and further enable the rack to smoothly enter the slot inside the cover body. At the same time, the descending rack will drive the gear meshing with it to rotate. Further, the rotating gear will drive the second bevel gear and the first bevel gear to mesh and drive each other, so that the stirring rod inside the first bevel gear rotates along the outside of the discharge cylinder together with itself. Meanwhile, during the rotation of the first bevel gear, the end of the spherical part inside the arc-shaped chute will resist the arc-shaped chute, and under the action of the inclined surface of the resisting block, gradually make the stirring rod slide downward while rotating with the first bevel gear. And when the stirring rod slides to the other end of the arc-shaped chute inside the resisting block, the notch part of the stirring rod will resist the bottom surface of the arc-shaped chute and drive the stirring rod to lift upward again, making the stirring rod return to the initial height. During this process, the bubbles that may form inside the barrel can be broken and stirred evenly; on the other hand, when the barrel is filled with the paint up to the predetermined weight, the discharge switch inside the filling machine is closed, and the inner cylinder inside the discharge cylinder will reset to its original position under the elastic force of the spring. This makes the gear and the rack mesh and drive in the reverse direction again, and then makes the stirring rod slide and reset to the initial position. During this process, the stirring rod can break the paint liquid that has been filled in the barrel, and at the same time, it can also make part of the paint liquid located in the center spread to the periphery of the barrel, reducing the generation of bubbles inside the barrel while strengthening the evenness of the paint inside the barrel, and improving the subsequent use quality of the paint as a whole.

[0016] 2. In the present invention, when the stirring rod slides inside the arc-shaped groove as the first bevel gear rotates, the stirring rod will also drive the connecting member and the outer cylinder to rotate outside the discharge cylinder. As a result, the scraper with a beveled side can scrape off the paint that may adhere to the surface of the discharge cylinder, and finally flow back into the barrel interior from the inclined surface of the scraper. At the same time, the protrusion at the bottom of the scraper will effectively wipe off the paint at the port part of the discharge cylinder. Along with the secondary reset of the stirring rod, the scraper and the protrusion will repeatedly clean the surface of the discharge cylinder to improve the utilization rate of the paint during the paint packaging process.

Detailed implementation manner

[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0031] Please refer to Figure 1-12, the present invention provides a technical solution: a barrel-shaped fluid intelligent packaging system. This solution solves the problem that the paint continuously flowing out from the discharge port collides with the paint in the barrel, generating a large number of bubbles and ultimately affecting the quality of the packaged paint. This solution makes corresponding improvements to the above problems, including a filling machine 1. One side of the filling machine 1 is provided with a base 3. Above the base 3 is provided a conveyor belt 5. At the bottom of the conveyor belt 5 is provided a pressure sensor 4. Above the conveyor belt 5 is provided a barrel 6 for containing paint. When the barrel 6 moves on the conveyor belt 5 to above the pressure sensor 4, the barrel 6 will automatically stop and be automatically filled. When the pressure sensor 4 detects that the total weight of the barrel 6 reaches the rated weight, the discharging effect of the filling machine 1 will automatically close, and the conveyor belt 5 will be driven to continue to convey. One side of the conveyor belt 5 is provided with a labeling machine 16 for labeling the outer wall of the barrel 6. One side of the conveyor belt 5 is also provided with a barrel separator 15 for separating the stacked barrels 6. One side of the conveyor belt 5 is also provided with a capping machine 17 for capping the port part of the barrel 6. After being capped by the capping machine 17, the barrel 6 will be palletized by a gantry palletizer 18 on one side of the conveyor belt 5 and finally packaged by a stretch wrapping machine 19. The above are all packaging processes existing in the prior art. One side of the filling machine 1 is provided with a discharge tube 2. Outside the discharge tube 2 is provided a cover 9 for shielding the opening part of the barrel 6. The cover 9 is fixedly connected to the discharge tube 2. The diameter of the cover 9 is larger than the diameter of the barrel 6. The cover 9 is located directly above the port of the barrel 6. During the process of continuously injecting paint into the barrel 6, it can prevent a part of the paint from colliding with each other and splashing outwards, reducing the waste of paint during the packaging process and also being beneficial to the protection of the packaging environment around the barrel 6. Outside the discharge tube 2 is provided a stirring assembly 7 for stirring the bubbles in the barrel 6; the stirring assembly 7 in this solution includes a bevel gear one 71 located outside the discharge tube 2. The bevel gear one 71 is located above the cover 9 and is rotatably connected to the discharge tube 2. Inside the bevel gear one 71 is provided a stirring rod 72. Inside the bevel gear one 71 is provided a square hole 73 for the stirring rod 72 to slide up and down. The stirring rod 72 passes through the bevel gear one 71 and the cover 9 and can freely slide up and down inside the bevel gear one 71 and the cover 9;

[0032] Furthermore, a driving assembly 8 is provided inside the discharge cylinder 2 to drive the stirring rod 72 to agitate the air bubbles inside the barrel body 6 during filling. The driving assembly 8 includes a connecting plate 81. A spring 82 is provided on the top of the connecting plate 81. One end of the spring 82 is fixedly connected to the discharge cylinder 2, and the other end of the spring 82 is fixedly connected to the connecting plate 81. A connecting block 83 is provided at the bottom of the connecting plate 81. One side of the connecting block 83 is fixedly connected to the connecting plate 81. An inner cylinder 810 is provided at one end of the connecting block 83 and fixedly connected thereto. The inner cylinder 810 is located inside the discharge cylinder 2 and can slide freely inside the discharge cylinder 2. The discharge cylinder 2 includes a vertical groove 21 for the connecting block 83 to slide. A U-shaped rod 84 is provided on one side of the connecting block 83. A rack 85 is provided at one end of the U-shaped rod 84. The two ends of the U-shaped rod 84 are respectively fixedly connected to the connecting block 83 and the rack 85. A gear 86 is provided on one side of the rack 85. The rack 85 and the gear 86 are meshed and driven with each other. A slot 10 for the rack 85 to insert is provided inside the cover body 9. A fixed shaft 88 is provided inside the gear 86. A second bevel gear 87 meshing with the first bevel gear 71 is provided outside the fixed shaft 88. One side of the second bevel gear 87 is fixedly connected to the gear 86, and the second bevel gear 87 and the gear 86 are simultaneously rotatably connected to the fixed shaft 88. A fixed block 89 is also provided outside the fixed shaft 88. One end of the fixed block 89 is fixedly connected to the cover body 9. The fixed block 89 is rotatably connected to the fixed shaft 88. A resisting block 11 is provided outside the discharge cylinder 2. The resisting block 11 is fixedly connected to the discharge cylinder 2. The stirring rod 72 includes a spherical part 722. The resisting block 11 includes an arc-shaped chute 111. The spherical part 722 is located inside the arc-shaped chute 111 of the resisting block 11. The stirring rod 72 further includes a notch 721. The notch 721 abuts against the bottom of the arc-shaped chute 111. The bottom of the resisting block 11 is shaped as a gradually descending arc surface. The top inner wall of the arc-shaped chute 111 always contacts the top surface of the spherical part 722;

[0033] When the barrel body 6 reaches the central part of the discharge tube 2 and automatic filling is carried out, the coating inside the discharge tube 2 will resist the top surface of the inner cylinder 810 inside it, and then the connecting block 83 outside the inner cylinder 810 can be lowered simultaneously. The connecting plate 81 will descend with the connecting block 83, and the spring 82 will be in a stretched state. The descending connecting block 83 will drive the U-shaped rod 84 and the rack 85 fixedly connected to it to descend simultaneously. During the descent, due to the special shape of the U-shaped rod 84 itself, it will not resist against the lower bevel gear two 87, and further enable the rack 85 to smoothly enter the slot 10 inside the cover body 9. At the same time, the descending rack 85 will drive the gear 86 meshing with it to rotate. Further, the rotating gear 86 will drive the bevel gear two 87 and the bevel gear one 71 to mesh and drive each other, so that the stirring rod 72 inside the bevel gear one 71 rotates along the outside of the discharge tube 2 together with itself. At the same time, during the rotation of the bevel gear one 71, the end of the spherical part 722 inside the arc-shaped chute 111 will resist against the arc-shaped chute 111, and under the action of the inclined surface of the resisting block 11, the stirring rod 72 will gradually slide downward while rotating with the bevel gear one 71. And when the stirring rod 72 slides to the other end of the arc-shaped chute 111 inside the resisting block 11, the notch 721 part of the stirring rod 72 will resist against the bottom surface of the arc-shaped chute 111 and drive the stirring rod 72 to continue to lift upward, so that the stirring rod 72 will return to the initial height again. During this process, the bubbles that may form inside the barrel body 6 can be broken and stirred evenly; on the other hand, when the barrel body 6 is filled with the predetermined coating weight, the discharge switch inside the filling machine 1 is closed, and the inner cylinder 810 inside the discharge tube 2 will reset to its original position under the elastic force of the spring 82. This makes the gear 86 and the rack 85 mesh and drive in the reverse direction again, and then makes the stirring rod 72 slide and reset to the initial position. During this process, the stirring rod 72 can break the coating liquid that has been filled in the barrel body 6, and at the same time, it can also make part of the coating liquid located in the center spread to the periphery of the barrel body 6. While reducing the generation of bubbles inside the barrel body 6, it also enhances the uniformity of the coating inside the barrel body 6, and overall improves the subsequent use quality of the coating.

[0034] In addition, an arc-shaped groove 91 for the stirring rod 72 to slide is provided inside the cover body 9 in this solution. A connecting member 14 is provided outside the stirring rod 72. The stirring rod 72 is slidably connected to the connecting member 14 and can rotate freely inside it. One end of the connecting member 14 is provided with an outer cylinder 13 and is fixedly connected to it. The outer cylinder 13 is rotatably connected to the discharge tube 2. A scraping blade 12 is provided at the bottom end of the outer cylinder 13. One end of the scraping blade 12 is fixedly connected to the outer cylinder 13. The side surface of the scraping blade 12 is an inclined surface that slopes downward. The scraping blade 12 includes a protruding portion 121, and the protruding portion 121 is located on one side of the bottom end of the discharge tube 2;

[0035] When the stirring rod 72 slides inside the arc-shaped groove 91 under the rotation of the first bevel gear 71, the stirring rod 72 will also drive the connecting member 14 and the outer cylinder 13 to rotate outside the discharge cylinder 2. As a result, the blade 12 with an inclined side surface can scrape the paint that may adhere to the surface of the discharge cylinder 2, and finally flow back into the interior of the barrel body 6 from the inclined surface of the blade 12. At the same time, the protrusion 121 at the bottom of the blade 12 can effectively wipe the paint at the port part of the discharge cylinder 2. Along with the secondary reset of the stirring rod 72, the blade 12 and the protrusion 121 will repeatedly clean the surface of the discharge cylinder 2 to improve the utilization rate of the paint during the paint packaging process.
