Description

Technical Field

[0001] This invention relates to the field of coating mixing technology, and more particularly to a coating mixing device for coating films. Background Technology

[0002] Coated films are produced by applying one or more layers of polyvinylidene chloride (PVDC) latex to various film materials using specialized equipment, resulting in films with high barrier properties. Their superior barrier properties are primarily manifested in their ability to reduce oxygen permeability by hundreds or thousands of times, thereby significantly improving shelf life, aroma retention, freshness preservation, and oil resistance.

[0003] When preparing coatings for film coating, multiple raw materials need to be mixed to form a relatively stable coating. Currently, in order to improve the lubricity of the mixed coating, a certain proportion of pearl powder solution needs to be added to the raw materials to ensure that the mixed coating has a certain degree of lubricity, which is convenient for subsequent spreading and coating on the surface of the object. However, during the mixing of pearl powder solution, when the amount of pearl powder solution is large, it is easy to produce agglomeration phenomenon during the mixing process with other substances, resulting in the formation of particulate matter inside the mixed solution, which is not convenient for subsequent coating.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. This invention, by providing a driving component, an intermittent feeding component, and a pre-storage device, allows the anti-coagulant and a small dose of pearl powder solution to be added sequentially to the mixing tank before the pearl powder solution is added to the mixture. This prevents agglomeration from occurring when the pearl powder solution is in large quantities during mixing. The driving component drives the spiral stirring rod to stir and mix the mixture inside the mixing tank and drives the intermittent feeding component. During the operation of the intermittent feeding component, the pre-storage device is also activated.

[0018] 2. The present invention, by providing a driving component, can drive the spiral stirring rod to stir and mix the mixed materials inside the mixing tank, and drive the intermittent feeding component to work;

[0019] 3. This invention, by incorporating an intermittent feeding component, can intermittently supply the contents stored inside the pre-storage device to the mixing tank. Simultaneously, the intermittent feeding component also intermittently opens the discharge pipe, facilitating the discharge of the solution deposited in the settling tank after mixing. When the intermittent feeding component is working, it first drives the arc-shaped strip to rotate via a turntable. During the rotation of the arc-shaped strip, it intermittently drives the contact rod to reciprocate. When the contact rod is not in contact with the arc-shaped strip, it is in its initial state. At this time, the storage cavity at the bottom of the feeding plate is misaligned with the opening, and the top of the wedge-shaped groove is connected to the bottom surface of the pre-storage tank. The anti-coagulation agent flows into the pre-storage tank from the discharge port on the bottom surface of the tank. Since the sealing plate and baffle are open at this time, the anti-coagulation agent can flow into the storage cavity for storage.

[0020] 4. This invention, by providing a pre-storage device, can quantitatively and intermittently deliver pearl powder solution into the mixing tank, and allow it to flow in together with an anti-coagulation agent. This can prevent the pearl powder solution from agglomerating during mixing. When the pre-storage device is working, when the contact rod contacts the arc-shaped strip and drives the feeding plate to slide to one side, the inclined action of the bottom surface inside the wedge-shaped groove can push the probe upward along the guide channel, thereby allowing the small dose of fixed-volume pearl powder solution stored inside the protective cover to flow into the storage cavity, and then from the storage cavity into the mixing tank.

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Please see Figure 1-8 The present invention provides a technical solution: a coating film mixing device, including a mixing tank 1, a spiral stirring rod 17 rotatably arranged between the inner walls of the two sides of the mixing tank 1, a driving assembly for driving the spiral stirring rod 17 to rotate on one side of the mixing tank 1, an inner cavity 15 is opened on the inner wall of the mixing tank 1 near the upper edge, an intermittent feeding assembly for feeding material into the mixing tank 1 is arranged inside the inner cavity 15, and a plurality of pre-storage devices for feeding material into the intermittent feeding assembly are arranged on the inner wall of the mixing tank 1 above the intermittent feeding assembly;

[0032] Multiple material cylinders 3 are equidistantly arranged on the top of the mixing box 1. A material trough 2 is opened on the top of the mixing box 1 near the rear edge. Two feed pipes 4 are fixed on the rear side of the mixing box 1 near the top edge. One end of each feed pipe 4 passes through the interior of the material trough 2.

[0033] The effect achieved is that, by providing a driving component, an intermittent feeding component, and a pre-storage device, the anti-coagulant and a small dose of pearl powder solution are sequentially added to the mixing tank 1 before the pearl powder solution is added to the mixture. This prevents agglomeration from occurring when the pearl powder solution is in large doses during mixing. The driving component drives the spiral stirring rod 17 to stir and mix the mixture inside the mixing tank 1, and also drives the intermittent feeding component. During the operation of the intermittent feeding component, the pre-storage device is also driven. The driving component, the intermittent feeding component, and the pre-storage device work in a coordinated and interconnected manner.

[0034] like Figure 1 , Figure 3 and Figure 4 As shown, the drive assembly includes a turntable 5, one end of a spiral stirring rod 17 extends to the outside of the mixing box 1, the turntable 5 is fixed to one end of the spiral stirring rod 17, a pulley 6 is fixed on one side of the turntable 5, and an arc-shaped strip 7 is fixed on the other side of the turntable 5 near the edge of the outer surface.

[0035] The effect it achieves is that it can drive the spiral stirring rod 17 to stir and mix the mixed material inside the mixing box 1, and drive the intermittent feeding component to work. It can be connected to an external power drive device through the pulley 6 to provide driving force for the entire device.

[0036] like Figure 1 - Figure 8As shown, the intermittent feeding assembly includes a feeding plate 16, which is slidably connected to the inner wall of the inner cavity 15. A reciprocating cavity 24 is provided on one side of the inner cavity 15 inside the mixing box 1. A contact rod 25 is provided inside the reciprocating cavity 24. One end of the contact rod 25 slides through the inner cavity 15 and is fixed to one side of the feeding plate 16. The other end of the contact rod 25 slides through the outer side of the mixing box 1 and is in contact with one side of the outer surface of the arc-shaped strip 7. A circular plate 26 is fixed to the outer surface of the contact rod 25. A reciprocating spring 27 is fixed between one side of the outer surface of the circular plate 26 and one side of the inner wall of the reciprocating cavity 24. Multiple storage cavities 21 are equidistantly provided at the bottom of the feeding plate 16, and multiple wedge-shaped grooves 22 are equidistantly provided at the top of the feeding plate 16. The inner bottom surface of each wedge-shaped groove 22 extends into the storage cavity 21 near one edge. Each wedge-shaped groove 22 has an opening on its inner bottom surface. There are guide channels 23, one side of which extends to the connection between the wedge-shaped groove 22 and the storage cavity 21. The inner top surface of the mixing box 1 has multiple openings 20 that penetrate into the inner cavity 15 at equal intervals. The multiple openings 20 are all opposite to the storage cavity 21. The bottom of the mixing box 1 has a bottom groove 10. The inner walls of the two sides of the bottom groove 10 are slidably connected to a movable plate 11. The bottom of the movable plate 11 is fixed with multiple discharge pipes 9 at equal intervals. The top of the multiple discharge pipes 9 are all connected to the top of the movable plate 11. The inner bottom surface of the mixing box 1 has a settling groove 18. The inner bottom surface of the settling groove 18 has multiple bottom holes 19 that penetrate into the bottom groove 10 at equal intervals. The multiple bottom holes 19 are all opposite to the discharge pipes 9. A connecting rod 12 is fixed to one side of the movable plate 11. One end of the connecting rod 12 is fixed with a side bracket 8. One end of the side bracket 8 is connected to the outer surface of the contact rod 25 near one edge.

[0037] The effect achieved is that while the intermittent feeding component is working, it also intermittently opens the discharge pipe 9, thereby facilitating the discharge of the solution that has settled in the settling tank 18 after mixing. When the intermittent feeding component is working, it first drives the arc-shaped strip 7 to rotate through the turntable 5. During the rotation of the arc-shaped strip 7, it intermittently drives the contact rod 25 to reciprocate. When the contact rod 25 is not in contact with the arc-shaped strip 7, it is in the initial state. At this time, the storage cavity 21 at the bottom of the feeding plate 16 is misaligned with the opening 20, and the top of the wedge-shaped groove 22 is connected to the bottom surface of the pre-storage tank 14. The anti-coagulant flows into the pre-storage tank 14 from the discharge port 13 on the bottom surface of the material tank 2. Since the sealing plate 29 and the baffle 28 are in the open state at this time, the anti-coagulant can flow into the storage cavity 21 for storage. When the arc-shaped bar 25 contacts the contact rod 25, it will cause the feeding plate 16 to slide to one side. When the storage cavity 21 slides above the opening 20, the anti-coagulation agent inside the storage cavity 21 can flow into the mixing box 1 from the opening 20. At the same time, it will trigger the pre-storage device to work. When the arc-shaped bar 7 does not contact the contact rod 25, the movable plate 11 inside the bottom groove 10 does not slide. At this time, the top of the discharge pipe 9 is opposite to the bottom hole 19, which pushes to one side to discharge the solution deposited in the settling tank 18. After the arc-shaped bar 7 contacts the contact rod 25, it will push the contact rod 25 to one side synchronously. During the sliding process of the contact rod 25, it will drive the movable plate 11 to slide synchronously inside the bottom groove 10 through the side bracket 8, so that the top of the discharge pipe 9 is misaligned with the bottom hole 19, thereby cutting off the bottom hole 19.

[0038] like Figure 1 , Figure 4 , Figure 5 and Figure 8As shown, the pre-storage device includes a probe 34. An adjustment cavity 32 is provided inside the mixing tank 1, located above the inner cavity 15. The probe 34 is located inside the adjustment cavity 32. An annular plate 33 is fixed to the outer surface of the probe 34. A return spring 37 is fixed between the top of the annular plate 33 and the inner top surface of the adjustment cavity 32. An inner flow channel 36 is provided inside the probe 34. Multiple through holes 35 extending into the inner flow channel 36 are provided on the outer surface of the probe 34 near its bottom edge. Near the top edge, multiple filter ports 43 are equidistantly provided, penetrating into the inner flow channel 36. The top of the probe 34 slides through into the inside of the material cylinder 3, and the bottom of the probe 34 slides through into the inside of the inner cavity 15. The bottom of the probe 34 slides against the inner bottom surface of the guide channel 23. Multiple pre-storage slots 14 are equidistantly provided on the inner top surface of the inner cavity 15. Each pre-storage slot 14 is located on one side of the regulating cavity 32. A side opening 31 penetrating into the pre-storage slot 14 is provided on the inner wall of one side of the regulating cavity 32. A baffle 28 is fixed to one inner wall, with the bottom of the baffle 28 flush with the top inner surface of the side opening 31. A support plate 30 is slidably disposed between the two inner walls of the side opening 31. One end of the support plate 30 is fixed to the annular plate 33, and the other end of the support plate 30 extends into the pre-storage tank 14. A sealing plate 29 is fixed to the other end of the support plate 30. The sealing plate 29 slides against the inner wall of the pre-storage tank 14, and the top of the sealing plate 29 is in contact with the bottom of the baffle 28. The pre-storage inner wall of the pre-storage tank 14 has a through-hole extending into the material trough 2. The bottom surface has a discharge port 13. A cylindrical cover 38 is fixed inside the bottom surface of the material cylinder 3. A protective cover 39 is slidably arranged between the inner walls of the cylindrical cover 38. Multiple support rods 42 are fixed at equal intervals between the inner walls of the protective cover 39 near the bottom edge. One end of each support rod 42 is fixed to the top of the probe 34. Multiple first leaks 41 are opened at equal intervals along the circumferential direction near the bottom edge of the outer surface of the cylindrical cover 38. Multiple second leaks 40 are opened at equal intervals along the circumferential direction near the top edge of the outer surface of the protective cover 39.

[0039] The effect achieved is that the pearl powder solution can be quantitatively and intermittently delivered into the mixing tank 1, and flows in together with the anti-coagulation agent to prevent the pearl powder solution from agglomerating during mixing. When the pre-storage device is working, when the contact rod 25 contacts the arc-shaped strip 7 and drives the feeding plate 16 to slide to one side, the probe 34 can be lifted upward along the guide channel 23 under the inclined action of the bottom surface inside the wedge groove 22, so that the small dose of fixed-volume pearl powder solution stored inside the protective cover 39 flows into the storage cavity 21, and then flows from the storage cavity 21 into the mixing tank 1. When the probe 34 is not lifted upward, the protective cover 39 is located inside the cylindrical cover 38. At this time, the first leak 41 and the second leak 40 are interconnected, and the pearl powder solution inside the material cylinder 3... Pearl powder solution flows into the protective cover 39 from the first outlet 41 and the second outlet 40 for storage. When the probe 34 is pushed upward, it will cause the protective cover 39 to slide upward towards the cylindrical cover 38. At this time, the first outlet 41 and the second outlet 40 are misaligned and opposite each other, blocking the pearl powder solution inside the material cylinder 3 from entering the protective cover 39. The pearl powder solution inside the protective cover 39 enters the inner flow channel 36 through the filter port 43, then flows into the guide channel 23 through the through hole 35, and finally flows into the storage cavity 21. At the same time, when the probe 34 slides upward, it will also cause the support plate 30 and the sealing plate 29 to slide upward, so that the top of the sealing plate 29 and the bottom of the baffle 28 fit together, thereby sealing the bottom of the pre-storage tank 14 and preventing the liquid inside from overflowing to the outside.

[0040] Positional relationship and operation of components in the feeding mechanism: In the initial state, the feeding plate 16 is stationary, the probe 34 is not lifted upwards, and the protective cover 39 is located inside the cylindrical cover 38. At this time, the first leak 41 and the second leak 40 are interconnected, and the filter port 43 on the probe 34 is located inside the part where the adjusting cavity 32 and the probe 34 intersect. At this time, the filter port 43 is closed, so the pearl powder solution inside the material cylinder 3 can flow into the protective cover 39 for storage from the first leak 41 and the second leak 40. When the feeding plate 16 slides to one side... When the probe 34 is lifted upward, it will cause the protective cover 39 to slide upward towards the cylindrical cover 38. At this time, the first outlet 41 and the second outlet 40 are misaligned and opposite to each other, blocking the pearl powder solution inside the barrel 3 from entering the protective cover 39. The filter 43 will also move upward and slide out from the inside of the part where the adjustment cavity 32 and the probe 34 intersect. At this time, the filter 43 is in the open state, so the pearl powder solution inside the protective cover 39 enters the inner flow channel 36 through the filter 43, then flows into the guide channel 23 through the through hole 35, and finally flows into the storage cavity 21.

[0041] Operation between sealing plate 29 and baffle 28: Initially, the feeding plate 16 is stationary, and the probe 34 is not lifted upwards. At this time, the sealing plate 29 is located below the pre-storage tank 14, while the baffle 28 is located in the middle of the pre-storage tank 14. Therefore, the bottom side of the sealing plate 29 and the top side of the baffle 28 are open. At this time, the upper and lower halves of the pre-storage tank 14 are interconnected, so the anti-coagulation agent can flow from the pre-storage tank 14 into the storage cavity 21 for storage. When the feeding plate 16 is in a stationary state, the probe 34 is not lifted upwards. When the probe 34 is pushed upward by sliding to one side, the sealing plate 29 is connected to the probe 34 through the support plate 30. Therefore, the upward sliding of the probe 34 can drive the sealing plate 29 to slide upward inside the pre-storage tank 14 until the sealing plate 9 slides to the middle part of the pre-storage tank 14, so that the top side of the sealing plate 19 and the bottom side of the baffle 28 fit together. At this time, the pre-storage tank 14 can be cut in the middle into upper and lower parts. At this time, the anti-coagulation agent in the pre-storage tank 14 cannot flow downward into the storage cavity 21.

[0042] Working principle: When using this device, first place the pearl powder solution inside the material cylinder 3 and the anti-coagulation agent inside the material tank 2. The turntable 5 can drive the spiral stirring rod 17 to stir and mix the mixture inside the mixing box 1. The turntable 5 can also drive the arc strip 7 to rotate. During the rotation of the arc strip 7, it will intermittently drive the contact rod 25 to reciprocate. When the contact rod 25 is not in contact with the arc strip 7, it is in the initial state. At this time, the storage cavity 21 at the bottom of the feeding plate 16 is misaligned with the opening 20. The top of the wedge groove 22 is connected to the bottom surface of the pre-storage tank 14. The anti-coagulation agent flows into the pre-storage tank 14 from the discharge port 13 on the bottom surface of the material tank 2. At this time, the sealing plate 29 and the baffle are connected. With the opening between 28, the anti-coagulant can flow into the storage chamber 21 for storage. When the arc-shaped strip 7 is not in contact with the contact rod 25, the movable plate 11 inside the bottom groove 10 does not slide. At this time, the top of the discharge pipe 9 is opposite to the bottom hole 19, causing it to push to one side and discharge the solution deposited inside the settling tank 18. When the contact rod 25 contacts the arc-shaped strip 7, it will cause the feeding plate 16 to slide to one side. When the storage chamber 21 slides above the opening 20, the anti-coagulant inside the storage chamber 21 can flow into the mixing tank 1 from the opening 20. When the contact rod 25 contacts the arc-shaped strip 7 and causes the feeding plate 16 to slide to one side, under the inclined action of the bottom surface inside the wedge-shaped groove 22, it can flow along... The guide channel 23 lifts the probe 34 upwards, allowing the small dose of fixed-volume pearl powder solution stored inside the protective cover 39 to flow into the storage cavity 21, and then from the storage cavity 21 into the mixing tank 1. After the arc-shaped strip 7 contacts the contact rod 25, it simultaneously pushes the contact rod 25 to one side. During the sliding process of the contact rod 25, the side bracket 8 drives the movable plate 11 to slide synchronously inside the bottom groove 10, causing the top of the discharge pipe 9 to be misaligned with the bottom hole 19, thus cutting off the bottom hole 19. When the probe 34 is not lifted upwards, the protective cover 39 is located inside the cylindrical cover 38. At this time, the first outlet 41 and the second outlet 40 are interconnected, and the pearl powder solution inside the material cylinder 3 flows from the first outlet 41 and... The second drain 40 flows into the protective cover 39 for storage. When the probe 34 is pushed upward, it will drive the protective cover 39 to slide upward towards the cylindrical cover 38. At this time, the first drain 41 and the second drain 40 are misaligned and opposite each other, blocking the pearl powder solution inside the material cylinder 3 from entering the protective cover 39. The pearl powder solution inside the protective cover 39 enters the inner flow channel 36 through the filter port 43, then flows into the guide channel 23 through the through hole 35, and finally flows into the storage cavity 21. At the same time, when the probe 34 slides upward, it will also drive the support plate 30 and the sealing plate 29 to slide upward, so that the top of the sealing plate 29 and the bottom of the baffle 28 fit together, thereby sealing the bottom of the pre-storage tank 14 and preventing the internal liquid from overflowing to the outside.

[0043] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
