Description

Technical Field

[0001] The invention relates to the technical field of ink mixers, in particular to a high temperature resistant UV inkjet ink and a processing and mixing device. Background Art

[0002] In the field of ink processing technology, especially for the production and preparation of high temperature resistant UV inkjet inks, the mixing device plays a vital role. The traditional high temperature resistant UV inkjet ink mixing device usually includes core components such as a rotating stirring barrel and a swinging stirring rod. During the stirring process, the various components of the ink (such as phenolic epoxy resin, light curing acrylic resin, phenolic resin, curing agent, reactive diluent, nano color paste, photoinitiator, etc.) need to be fully mixed in the stirring barrel. We found the following problems in actual use:

[0003] 1. Manual cleaning of the stirring rod is inefficient: the stirring rod is adhered to ink components and needs to be frequently cleaned manually, which increases the difficulty of operation and labor costs;

[0004] 2. The quality is affected by the degree of ink mixing judged by human experience: Operators often need to judge the degree of ink mixing through experience and trial and error, which is not only inefficient but also may lead to unstable ink quality;

[0005] The reasons for the above problems are:

[0006] 1. Due to the complex composition and high viscosity of the ink, the stirring rod is prone to adhere to different ink components during the stirring process;

[0007] 2. There is no corresponding cleaning structure on the stirring rod;

[0008] 3. Operators rely too much on personal experience and have insufficient quality control measures;

[0009] 4. Lack of effective quality control measures to monitor and evaluate the mixing uniformity of inks in real time, resulting in unstable product quality.

[0010] In summary, the problems that arise in the actual use of traditional high-temperature resistant UV inkjet ink mixing devices are mainly caused by the ink composition, unreasonable design of the stirring rod and the lack of real-time monitoring means. Therefore, we propose a high-temperature resistant UV inkjet ink and processing mixing device. Summary of the invention

[0011] A technical problem to be solved by the present application is: how to design a processing and mixing device for high temperature resistant UV inkjet ink that can both clean the stirring rod and monitor the mixing degree of the ink.

[0024] A scraping unit, which is arranged on the mixing body and connected to the separation block and the mounting frame, and is used to drive the mounting frame and the separation block to shift on the mixing rod body when the swing frame swings;

[0025] The monitoring unit is arranged between the mounting frame and the separation block, and can monitor the mixing condition of the ink by observing the relative displacement between the separation block and the mounting frame at each resetting.

[0026] In some embodiments, the scraping unit includes a support rod arranged on the mixing body, a tension spring is arranged at the end of the swing frame, the end of the tension spring is connected to the mounting frame, a driving member is arranged between the mounting frame and the support rod, and is used to drive the mounting frame and the separation block to move downward along the mixing rod body when the swing frame swings, and a clamping member is arranged between the support rod and the driving member for adjustment during installation.

[0027] In some embodiments, the driving member includes an arc-shaped push rod arranged on the support rod, the clamping member is arranged between the support frame and the arc-shaped push rod, and a wedge block matching the arc-shaped push rod is arranged on the side of the installation frame close to the arc-shaped push rod, and an opening is arranged at the bottom of the wedge block to ensure that the wedge block and the installation frame can move downward normally after being squeezed by the arc-shaped push rod.

[0028] In some embodiments, the clamping member includes two positioning frames respectively arranged on both sides of the support rod, the positioning frames are rotatably provided with screws, the screws are threadedly connected with clamps, the clamps are slidably connected to the positioning frames, the support rod is located between the positioning frames and the clamps, and the arc-shaped top rod and the two positioning frames are rotatably connected.

[0029] In some embodiments, the monitoring unit includes an observation layer arranged on the separation block, a transparent section is provided at the bottom of the installation frame, and a reset member is provided between the installation frame and the separation block to ensure that the separation block is detached and reset from the viscous ink on the mixing rod body.

[0030] In some embodiments, the reset member includes two reset springs respectively arranged on both sides of the interior of the installation frame, and the ends of the reset springs are connected to both sides of the separation block.

[0031] In some embodiments, the reset member includes two rotating shafts respectively rotatably arranged on both sides of the interior of the installation frame, and eccentric counterweight blocks are arranged on the two rotating shafts. A shift member is arranged between the two rotating shafts and the separation block, which is used to use the eccentric counterweight blocks to drive the separation block to reset.

[0034] The present invention has at least the following beneficial effects:

[0035] 1. The ink has achieved excellent high temperature resistance through a carefully designed composition ratio, so that the printed images or text can still maintain clarity and color stability in a high temperature environment. Among them, polyurethane acrylate resin as the main component provides good adhesion and film-forming properties, ensuring the printing effect and durability of the ink. Isobornyl acrylate (IBOA) and dicyclopentyl methacrylate (HDCPMA) as monomers not only enhance the fluidity and curing speed of the ink, but also further improve the heat resistance and chemical stability of the ink;

[0036] At the same time, the use of (2,4,6-trimethylbenzoyl) diphenylphosphine oxide as a photoinitiator allows the ink to cure quickly under ultraviolet light, greatly shortening the production cycle and improving production efficiency. Phthalocyanine blue as a pigment gives the ink a bright and lasting blue hue, while the addition of titanium dioxide filler improves the whiteness and hiding power of the ink, making the printing effect fuller and more three-dimensional;

[0037] In addition, the ink also adds an appropriate amount of leveling agent and defoaming agent, which effectively improves the fluidity and surface tension of the ink, avoids problems such as bubbles and pinholes during the printing process, and further improves the printing quality and aesthetics.

[0038] 2. Automatic scraping of ink residue: The scraping unit can automatically drive the installation frame and the separation block to shift on the mixing rod body when the swing frame swings, effectively scraping off the ink components adhering to the mixing rod body, reducing the frequency and difficulty of manual cleaning, reducing labor costs, and improving production efficiency;

[0039] 3. Real-time monitoring of ink mixing: The setting of the monitoring unit can directly reflect the mixing condition of the ink by observing the relative displacement between the separation block and the mounting frame at each reset, avoiding the operator's reliance on experience and trial and error to judge the mixing degree of the ink, and improving the uniformity of the ink mixing and the stability of the product quality; BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0052] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0053] Example 1: Please refer to Figure 1-Figure 7 , the present invention provides a technical solution:

[0054] A high temperature resistant UV inkjet ink, comprising the following components by weight percentage:

[0055] Resin: 35% polyurethane acrylate;

[0056] Monomer: 20% isobornyl acrylate (IBOA);

[0057] Monomer: 15% dicyclopentyl methacrylate (HDCPMA);

[0058] Photoinitiator: 8% (2,4,6-trimethylbenzoyl) diphenylphosphine oxide;

[0059] Pigment: 10% phthalocyanine blue;

[0060] Filler: 5% titanium dioxide;

[0061] Additives: 7% leveling agent, defoaming agent.

[0062] A high temperature resistant UV inkjet ink processing and mixing device includes a mixing body 1, a mixing cylinder 9 and a swing frame 10. The mixing body 1 is a common existing structure, which can provide driving force for the mixing cylinder 9 and the swing frame 10 to ensure normal mixing of the ink. No further details are given here, and the mixing body 1 also includes:

[0063] A mixing rod body 11, which is disposed on the swing frame 10 and can be placed inside the mixing barrel 9;

[0064] A separation block 12, the separation block 12 is slidably disposed on the mixing rod body 11;

[0065] An installation frame 13, the installation frame 13 is sleeved on the outside of the mixing rod body 11, and the separation block 12 is slidably arranged inside the installation frame 13;

[0066] The scraping unit 2 is arranged on the mixing body 1 and connected with the separation block 12 and the mounting frame 13, and is used to drive the mounting frame 13 and the separation block 12 to shift on the mixing rod body 11 when the swing frame 10 swings;

[0067] The scraping unit 2 includes a support rod 21 arranged on the mixing body 1, a tension spring 22 is arranged at the end of the swing frame 10, and the end of the tension spring 22 is connected to the mounting frame 13. A driving member 3 is arranged between the mounting frame 13 and the support rod 21, which is used to drive the mounting frame 13 and the separation block 12 to move downward along the mixing rod body 11 when the swing frame 10 swings. A clamping member 4 is arranged between the support rod 21 and the driving member 3 for adjustment during installation;

[0068] The driving member 3 includes an arc-shaped push rod 31 arranged on the support rod 21, the clamping member 4 is arranged between the support frame and the arc-shaped push rod 31, and a wedge block 32 matching the arc-shaped push rod 31 is arranged on the side of the installation frame 13 close to the arc-shaped push rod 31, and an opening is arranged at the bottom of the wedge block 32 to ensure that the wedge block 32 and the installation frame 13 can move down normally after being squeezed by the arc-shaped push rod 31;

[0069] The clamping member 4 includes two positioning frames 41 respectively arranged on both sides of the support rod 21, the positioning frames 41 are rotatably provided with screws 42, the screws 42 are threadedly connected with clamping plates 43, the clamping plates 43 are slidably connected with the positioning frames 41, the support rod 21 is located between the positioning frames 41 and the clamping plates 43, and the arc-shaped top rod 31 and the two positioning frames 41 are rotatably connected;

[0070] The monitoring unit 5 is arranged between the mounting frame 13 and the separation block 12. By observing the relative displacement between the separation block 12 and the mounting frame 13 at each reset, the mixing of the ink can be monitored. Because when the ink is mixed, water or a diluent needs to be added to adjust the concentration and viscosity. The monitoring principle of this scheme is to use the characteristic that the ink can absorb the separation block 12. After dilution with water, the absorption capacity will be weakened, and the residual ink on the mixing rod body 11 will also be reduced, so that the relative displacement between the separation block 12 and the mounting frame 13 will be reduced at each reset.

[0071] The monitoring unit 5 includes an observation layer 51 arranged on the separation block 12, a transparent section 52 is arranged at the bottom of the installation frame 13, a reset member 6 is arranged between the installation frame 13 and the separation block 12, and is used to ensure that the separation block 12 is separated and reset from the viscous ink on the mixing rod body 11, and a sliding groove and a sliding block are arranged between the installation frame 13 and the separation block 12, so that the two cannot be separated, and an observation layer 51 is arranged on the separation block 12, and the observation layer 51 is a striking color, and the installation frame 13 and the separation block 12 are tightly fitted, and the ink adhering to the side of the separation block 12 can be scraped off, and a transparent section 52 is arranged at the bottom of the installation frame 13, so that the staff can observe the relative displacement distance of the separation block 12;

[0072] The reset member 6 includes two reset springs 61 respectively arranged on both sides of the installation frame 13. The ends of the reset springs 61 are connected to both sides of the separation block 12. When the installation frame 13 moves up, the separation block 12 can be driven to move up synchronously through the reset springs 61.

[0073] When in use, the clamping member 4 can adjust the position of the arc-shaped ejector rod 31 according to the demand, and the mixing body 1 provides driving force for the device, so that the swing frame 10 drives the mixing rod body 11 to swing and stir the ink in the mixing barrel 9, and the mixing barrel 9 rotates continuously. The scraping unit 2 pulls the mounting frame 13 to move through the swing of the swing frame 10, and the tension spring 22 is stretched. The wedge block 32 on the mounting frame 13 cooperates with the arc-shaped ejector rod 31 on the support rod 21, and the mounting frame 13 moves downward along the mixing rod body 11. The separation block 12 moves downward synchronously with the mounting frame 13. When moving downward, it can push down the ink on the surface of the mixing rod body 11, and so on and so forth to ensure the scraping effect;

[0074] The monitoring unit 5 monitors the ink mixing condition by manually observing the relative displacement between the separation block 12 and the mounting frame 13. The observation layer 51 on the separation block 12 and the transparent section 52 at the bottom of the mounting frame 13 are convenient for observation. The reset spring 61 drives the separation block 12 to reset when the mounting frame 13 moves upward. The sliding groove and the sliding block ensure that the mounting frame 13 is tightly fitted to the separation block 12 and scrapes off the ink adhered to the side of the separation block 12. The whole process realizes the integration of ink stirring, automatic cleaning and mixing degree monitoring, thereby improving production efficiency and product quality.

[0075] Example 2: Please refer to Figure 1-Figure 5 , Figure 8-Figure 11 , the present invention provides a technical solution:

[0076] Different from Example 1, this solution provides another implementation of the reset member 6:

[0077] The reset member 6 includes two rotating shafts 62 rotatably arranged on both sides of the inside of the installation frame 13, and eccentric counterweights 63 are arranged on the two rotating shafts 62. A shifting member 7 is arranged between the two rotating shafts 62 and the separation block 12, which is used to drive the separation block 12 to reset by using the eccentric counterweights 63. The two counterweights are arranged on the side close to the installation frame 13, which is used to prevent the separation block 12 from reciprocating after resetting.

[0078] The shifting member 7 includes a driving gear 71 arranged on the rotating shaft 62, a guide frame 72 is arranged inside the mounting frame 13, a transmission rack 73 meshing with the driving gear 71 is slidably arranged inside the guide frame 72, a connecting rod 74 is arranged between the transmission rack 73 and the separation block 12, and the separation block 12 is synchronously shifted by the connecting rod 74 and the transmission rack 73. When the separation block 12 is adsorbed by ink and slides in the mounting frame 13, the eccentric counterweight block 63 rotates, and the separation block 12 continues to move up, and the adsorption force is cancelled. At this time, under the action of the gravity of the eccentric counterweight block 63, the rotating shaft 62 and the driving gear 71 are driven to rotate, thereby driving the transmission rack 73 and the separation block 12 to reset;

[0079] The positioning member 8 includes a plurality of positioning springs 81 respectively arranged on the eccentric counterweight block 63, and a locking ball 82 is arranged at the end of the positioning spring 81. The eccentric counterweight block 63 is provided with a plurality of mounting grooves 83 for adjusting the displacement of the positioning spring 81 and the locking ball 82, and the inner wall of the mounting frame 13 is provided with a plurality of slots 84 respectively used in conjunction with the locking ball 82.

[0080] When in use, the clamping member 4 can adjust the position of the arc-shaped ejector rod 31 according to the demand, and the mixing body 1 provides driving force for the device, so that the swing frame 10 drives the mixing rod body 11 to swing and stir the ink in the mixing barrel 9, and the mixing barrel 9 rotates continuously. The scraping unit 2 pulls the mounting frame 13 to move through the swing of the swing frame 10, and the tension spring 22 is stretched. The wedge block 32 on the mounting frame 13 cooperates with the arc-shaped ejector rod 31 on the support rod 21, and the mounting frame 13 moves downward along the mixing rod body 11. The separation block 12 moves downward synchronously with the mounting frame 13. When moving downward, it can push down the ink on the surface of the mixing rod body 11, and so on and so forth to ensure the scraping effect;

[0081] The monitoring unit 5 monitors the ink mixing condition by manually observing the relative displacement between the separation block 12 and the mounting frame 13. The observation layer 51 on the separation block 12 and the transparent section 52 at the bottom of the mounting frame 13 are convenient for observation. The separation block 12 is provided with a striking observation layer 51, and the bottom of the mounting frame 13 is provided with a transparent section 52;

[0082] When the separation block 12 moves due to ink adhesion, the reset member 6 (eccentric weight block 63 and shift member 7) starts to work. At this time, the separation block 12 is pulled out from the mounting frame 13. At this time, it is the moment to observe the mixing degree. Then the eccentric weight block 63 rotates through the rotating shaft 62, driving the driving gear 71 to rotate, and the transmission rack 73 moves, and then the separation block 12 is driven to reset through the connecting rod 74. The setting of the positioning member 8 (positioning spring 81 and locking ball 82) ensures that the separation block 12 will not swing back and forth after being reset.

[0083] The specific process is as follows: when the separation block 12 is adsorbed by ink and slides in the mounting frame 13, the eccentric counterweight block 63 rotates accordingly. When the adsorption force is cancelled, the eccentric counterweight block 63 drives the rotating shaft 62 and the driving gear 71 to rotate under the action of gravity. The driving gear 71 meshes with the transmission rack 73, driving the transmission rack 73 and the connecting rod 74 to move, thereby resetting the separation block 12. At the same time, the positioning spring 81 and the locking ball 82 cooperate with the card slot 84 to ensure that the separation block 12 is stably reset.

[0084] By observing the displacement of the separation block 12 in the transparent section 52, the staff can judge the degree of mixing of the ink. When the relative displacement between the separation block 12 and the mounting frame 13 reaches a certain degree, it means that the ink has been mixed evenly. The entire device improves the production efficiency and product quality of the ink through the design of the scraping unit 2 and the monitoring unit 5.

[0085] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0086] While the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that many changes, modifications, substitutions and variations can be made to the embodiments without departing from the principles and spirit of the invention.
