Description

Technical Field

[0001] This utility model relates to the field of UV coating mixing, specifically a mixer for producing solvent-free UV coatings. Background Technology

[0002] UV coatings refer to coatings that are cured by UV radiation. UV-cured coatings can be used for ink printing and exposed to UV irradiation. Their solid content can be as high as 100%, so there are no volatile components and no environmental pollution. The high solid content also allows them to be used for very thin films. UV-cured coatings can also be used to coat glass and plastics, wood, aluminum beverage bottles, etc.

[0003] The main components of UV coatings include photosensitive resin, crosslinking monomer, photosensitizer, solvent, and additives. The raw materials are mixed using a mixer according to the specified ratio. However, some mixers can only perform the mixing function. Since the raw materials of UV coatings contain lumps of particulate matter, it is inconvenient to crush the particulate matter into powder. Other equipment is required for powdering, which affects production efficiency. Direct mixing makes it difficult for the particulate matter to dissolve, resulting in a decrease in the quality of UV coatings. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, some mixers can only perform the function of stirring. Since the raw materials of UV coatings contain lumpy particles, it is inconvenient to crush the particles into powder. Other equipment is required for powdering, which affects production efficiency. Direct stirring leads to the particles not dissolving easily, resulting in a decrease in the quality of UV coatings. This utility model proposes a mixer for the production of solvent-free UV coatings.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a mixer for producing solvent-free UV coatings, including a mixing tank, a top cover fixedly connected to the top of the mixing tank, a stirring motor fixedly installed on one side of the top cover, a liquid inlet pipe fixedly connected to one side of the top cover, a discharge pipe fixedly connected to the surface of the mixing tank, and an automatic feeding mechanism provided on the surface of the mixing tank.

[0006] The automatic feeding mechanism includes a feeding pipe, one end of which is fixedly connected to the surface of the mixing tank. A feed pipe is fixedly connected to the surface of the feeding pipe. A drive motor is fixedly installed at one end of the feeding pipe. A transmission rod is fixedly connected to the output end of the drive motor. An auger is fixedly connected to one end of the transmission rod. One end of the auger is rotatably connected to the inner wall of the feeding pipe. A first transmission wheel is fixedly connected to the surface of the transmission rod. Two pressing rollers are rotatably connected to the inner wall of the feed pipe. A gear is fixedly connected to one end of each pressing roller, and the teeth of the two gears mesh with each other.

[0007] Preferably, a rotating rod is rotatably connected to the inner cavity of the feed pipe, and a drain cleaner is fixedly connected to one end of the rotating rod, with the drain cleaner disposed in the inner cavity of the feed pipe.

[0008] Preferably, a second transmission wheel is fixedly connected to one end of the rotating rod, a first transmission belt is movably sleeved on the surface of the second transmission wheel and the surface of the first transmission wheel, and a third transmission wheel is fixedly connected to one side of the second transmission wheel.

[0009] Preferably, a fourth transmission wheel is fixedly connected to one side of the gear, and a second transmission belt is movably sleeved on the surface of the fourth transmission wheel and the surface of the third transmission wheel.

[0010] Preferably, a mounting plate is fixedly connected to one side of the feed pipe. The mounting plate is U-shaped, and a scraper is slidably connected to the inner cavity of the mounting plate. One side of the scraper is attached to the surface of the rolling roller.

[0015] This invention utilizes an automatic feeding mechanism. A drive motor rotates a transmission rod, which in turn rotates a first transmission wheel. This first transmission wheel, in turn, rotates a first transmission belt. Simultaneously, the first transmission belt rotates a second transmission wheel, which in turn rotates a third transmission wheel. The third transmission wheel, in turn, rotates the second transmission belt. The second transmission belt, in turn, rotates a fourth transmission wheel and a gear. Because the teeth of the two gears mesh, the gear-driven relative rotation of two grinding rollers crushes the raw materials of the coating into powder. The powdered raw material... The material falls into the conveying pipe through the feed pipe, and the transmission rod, driven by the drive motor, simultaneously drives the auger to rotate. The powdered raw material is conveyed to the inside of the mixing tank through the spiral auger along the conveying pipe. This achieves the integration of raw material powdering, raw material conveying, and raw material mixing, improving production efficiency and the quality of UV coatings. It solves the problems of some mixers that can only perform the mixing function, and because the raw materials of UV coatings contain lumps of particulate matter, it is inconvenient to crush the particulate matter into powder. Other equipment is required for powdering, which affects production efficiency. Direct mixing makes it difficult for the particulate matter to dissolve, resulting in a decrease in the quality of UV coatings. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0023] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0024] This application discloses a mixer for producing solvent-free UV coatings. (Refer to...) Figures 1 to 3 A mixer for producing solvent-free UV coatings includes a mixing tank 1, a top cover 2 fixedly connected to the top of the mixing tank 1, a mixing motor 3 fixedly installed on one side of the top cover 2, a liquid inlet pipe 4 fixedly connected to one side of the top cover 2, a discharge pipe 5 fixedly connected to the surface of the mixing tank 1, and an automatic feeding mechanism 6 provided on the surface of the mixing tank 1.

[0025] The automatic feeding mechanism 6 includes a feeding pipe 601, one end of which is fixedly connected to the surface of the mixing tank 1. A feed pipe 602 is fixedly connected to the surface of the feeding pipe 601. A drive motor 603 is fixedly mounted on one end of the feeding pipe 601. A transmission rod 604 is fixedly connected to the output end of the drive motor 603. An auger 605 is fixedly connected to one end of the transmission rod 604. One end of the auger 605 is rotatably connected to the inner wall of the feeding pipe 601. A first transmission wheel 606 is fixedly connected to the surface of the transmission rod 604. Two pressing rollers 607 are rotatably connected to the inner wall of the feed pipe 602. One end of each pressing roller 607 is fixedly connected to... There are two gears 608, whose teeth mesh with each other. A rotating rod 7 is rotatably connected to the inner cavity of the feed pipe 602. One end of the rotating rod 7 is fixedly connected to a drain cleaner 8, which is located inside the inner cavity of the feed pipe 602. A second transmission wheel 9 is fixedly connected to one end of the rotating rod 7. A first transmission belt 15 is movably fitted onto the surface of the second transmission wheel 9 and the surface of the first transmission wheel 606. A third transmission wheel 16 is fixedly connected to one side of the second transmission wheel 9. A fourth transmission wheel 17 is fixedly connected to one side of the gears 608. A second transmission belt 18 is movably fitted onto the surface of the fourth transmission wheel 17 and the surface of the third transmission wheel 16. This solvent-free UV coating production agitator... The mixer feeds the raw materials for the coating through the feed pipe 602. It then activates the drive motor 603, which rotates the transmission rod 604. Simultaneously, the transmission rod 604 rotates the first transmission wheel 606, which in turn rotates the first transmission belt 15. The first transmission belt 15, in turn, rotates the second transmission wheel 9, which in turn rotates the third transmission wheel 16. The third transmission wheel 16, in turn, rotates the second transmission belt 18. The rotation of the second transmission belt 18 then rotates the fourth transmission wheel 17 and a gear 608. Because the two gears 608... The teeth of the rollers mesh with each other, so the two rollers 607 rotate relative to each other through the gear 608 to crush the raw materials of the coating into powder. The powdered raw materials fall into the conveying pipe 601 through the feed pipe 602. The transmission rod 604 drives the auger 605 to rotate under the drive of the drive motor 603. The powdered raw materials are conveyed to the inside of the mixing tank 1 through the spiral auger 605 along the conveying pipe 601. The mixing motor 3 stirs and blends the raw materials inside the mixing tank 1 to form UV coating. Thus, the mixer for producing solvent-free UV coating integrates raw material powdering, raw material conveying and raw material mixing, improving production efficiency and the quality of UV coating.

[0026] In addition, the rotation of the second transmission wheel 9 drives the rotation rod 7 to rotate, and the rotation of the rotation rod 7 drives the unblocker 8 to rotate in the inner cavity of the feed pipe 602, thereby unblocking the powdered raw materials and minimizing the blockage of the powdered raw materials inside the feed pipe 602.

[0027] Reference Figure 3 A mounting plate 10 is fixedly connected to one side of the feed pipe 602. The mounting plate 10 is U-shaped. A scraper 11 is slidably connected to the inner cavity of the mounting plate 10. One side of the scraper 11 is attached to the surface of the pressing roller 607. The scraper 11 can scrape off the raw material adhering to the surface of the pressing roller 607 during the pressing process. The scraped raw material falls through the gap between the pressing roller 607 and the inner wall of the feed pipe 602, so as to avoid the attachment and residue of raw material and the loss of raw material.

[0028] Reference Figure 4 A limiting plate 13 is fixedly connected to one side of the scraper 11. The surface of the limiting plate 13 is slidably connected to the inner cavity of the mounting plate 10. Through the limiting plate 13, the scraper 11 can slide along the inner wall of the mounting plate 10, so as to avoid collisions that could damage the scraper 11. The position of the retracted scraper 11 is limited by the limiting plate 13.

[0029] Reference Figure 4 A spring 14 is fixedly connected to one side of the limiting plate 13. There are several springs 14. One end of the spring 14 is fixedly connected to the inner wall of the mounting plate 10. Through the spring 14, the spring 14 can reset the scraper 11 and ensure that the scraper 11 and the rolling roller 607 are tightly attached.

[0030] Reference Figure 1 A support member 12 is provided on the surface of the conveying pipe 601. The support member 12 includes an arc-shaped plate 1201. The inner wall of the arc-shaped plate 1201 is attached to the surface of the conveying pipe 601. A support rod 1202 is fixedly connected to the surface of the arc-shaped plate 1201. A base plate 1203 is fixedly connected to one end of the support rod 1202. Through the provided support member 12, the arc-shaped plate 1201 is attached to the conveying pipe 601. The support rod 1202 and the base plate 1203 cooperate to support the conveying pipe 601 and ensure the stability of the automatic conveying mechanism 6.

[0031] Working principle: The raw materials for the coating are fed into the feed pipe 602. The drive motor 603 is activated, which drives the transmission rod 604 to rotate. Simultaneously, the transmission rod 604 rotates the first transmission wheel 606, which in turn rotates the first transmission belt 15. The rotation of the first transmission belt 15, in turn, rotates the second transmission wheel 9, which in turn rotates the third transmission wheel 16. The rotation of the third transmission wheel 16, in turn, rotates the second transmission belt 18. The rotation of the second transmission belt 18 then rotates the fourth transmission wheel 17 and a gear 608. Because the teeth of the two gears 608 mesh, the gears 608 drive the two rollers 607 to rotate relative to each other, feeding the raw materials for the coating. The raw materials are crushed into powder, and the powdered raw materials fall into the conveying pipe 601 through the feed pipe 602. The transmission rod 604 drives the auger 605 to rotate under the drive motor 603. The powdered raw materials are conveyed to the inside of the mixing tank 1 through the spiral auger 605. The mixing motor 3 mixes and blends the raw materials inside the mixing tank 1 to form UV coating. The second transmission wheel 9 rotates while driving the rotating rod 7 to rotate. The rotating rod 7 rotates while driving the unblocker 8 to rotate in the inner cavity of the feed pipe 602, thereby unblocking the powdered raw materials and avoiding the powdered raw materials from clogging the inside of the feed pipe 602. Thus, this mixer for producing solvent-free UV coatings integrates raw material powdering, raw material conveying and raw material mixing, improving production efficiency and the quality of UV coatings.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
