Description
Technical Field
[0001] This utility model belongs to the field of ink production technology, specifically relating to a vacuum mixer for ink material production. Background Technology
[0002] In the production process of ink materials, the mixing process is one of the core links that determines the quality of the product. It is necessary not only to achieve uniform dispersion of components such as pigments, resins, solvents and various additives, but also to strictly control the air mixing during the mixing process to avoid defects such as bubbles and layering in the finished ink, which will affect the color uniformity and adhesion of subsequent printed products. Vacuum mixers, with their advantage of completing the mixing operation in a closed vacuum environment, effectively solve the problem of air mixing and have become the mainstream mixing equipment in the ink production field. In the actual process flow of ink production, in addition to mixing and dispersion, the screening and pretreatment of raw materials is equally important. Since solid raw materials such as pigments are prone to agglomeration during storage and transportation, and may be mixed with a small amount of impurities, if they are directly put into the mixing tank for mixing, not only will the agglomerates not be fully dispersed, affecting the uniformity of the ink, but it may also cause wear on the internal parts of the mixing equipment, and even affect the service life of the ink rollers and the printing quality during the printing process. Therefore, the raw materials must undergo strict screening before entering the vacuum mixer to remove impurities and break up agglomerates.
[0003] The existing, industry-standard process typically separates screening and mixing into two independent steps. Raw materials are pre-treated using separate screening equipment such as vibrating screens or rotary screens. After screening, the qualified materials are then transferred to the inlet of a vacuum mixer via manual handling or pipeline transport for mixing. While this separate process meets basic production needs, it has several shortcomings in practical application. The process is cumbersome, increasing the complexity of the production flow and extending the overall production cycle. Furthermore, during the transfer of raw materials from screening to the mixer, they are susceptible to environmental influences, such as absorbing moisture from the air and incorporating dust and other impurities. This is especially problematic for some moisture-absorbing and easily oxidized ink raw materials, directly leading to performance degradation and affecting the quality of the final ink product. Additionally, the independently installed screening equipment requires additional production space, increasing equipment investment and site rental costs. Furthermore, dedicated operators are needed for screening and material handling, raising labor costs. Utility Model Content
[0004] The purpose of this invention is to provide a vacuum mixer for ink material production, so as to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: A vacuum mixer for ink material production, comprising:
[0006] The frame has a mixing chamber for stirring ink materials connected to its top. A vacuum pump is installed on one side of the mixing chamber, and one end of the vacuum pump is connected to the mixing chamber through a pipe.
[0007] A sealing cover is hinged to the top of the frame. A screening component for screening ink materials is provided at the center of the top of the sealing cover. The screening component includes a screening base and a screening chamber. The screening base is connected to the center of the top of the sealing cover and the screening chamber is located on the top of the screening base. A vibration motor is installed on the surface of the screening chamber. The vibration motor generates vibration and drives the screening chamber to vibrate, so that the vibrating screening chamber can screen the ink materials put into the mixing chamber.
[0008] An electric push rod is located on both sides of the mixing chamber and is used to push the sealing cover to open and close.
[0009] Preferably, a pipe is connected between the screening seat and the sealing cover, and a butterfly valve is installed on the pipe. The screening chamber is connected to the pipe through a flexible hose. Through the cooperation of the pipe, butterfly valve and flexible hose, the sealed conveying of the screened raw material is realized, and the connection is stable to adapt to the vibration of the screening chamber.
[0010] Preferably, a number of dampers are connected between the screening chamber and the screening base, and a filter screen is fixed in the screening chamber by a number of bolts. The dampers buffer vibration and impact to protect the equipment, and the detachable filter screen realizes raw material screening and is easy to clean or replace.
[0011] Preferably, one end of the electric push rod is hinged to the mixing chamber via a hinge seat, and the other end is hinged to the sealing cover via a hinge seat. The bidirectional hinge structure enables the electric push rod to stably drive the opening and closing of the sealing cover, while ensuring the sealing cover and the mixing chamber are properly fitted and sealed.
[0012] Preferably, one side of the mixing chamber is connected to two sets of hinge frames, and one end of the sealing cover is hinged to the hinge frame via a pin. The hinge frame provides a stable hinge fulcrum for the sealing cover, ensuring the coaxiality of the sealing cover during rotation to avoid sealing failure.
[0013] Preferably, a stirring rod is rotatably connected to the stirring chamber via a bearing, and a spiral blade is connected to the stirring rod. The stirring rod drives the spiral blade to rotate, thereby realizing the three-dimensional shearing and mixing dispersion of the ink raw materials in the stirring chamber.
[0014] Preferably, a servo motor is installed at one end of the mixing chamber, and the output shaft of the servo motor is connected to the mixing rod. The servo motor can provide rotational power to the mixing rod, and the servo motor speed can be adjusted to adapt to the mixing requirements of raw materials with different viscosities.
[0015] Preferably, a discharge shell is provided at the bottom center of the mixing chamber, and grooves are provided on both sides of the discharge shell. A discharge port is opened at the bottom of the mixing chamber and inside the discharge shell. A sealing plate for sealing the discharge port is slidably connected between the two sets of grooves to form a discharge structure. The discharge port can be sealed and opened by the slidable sealing plate to ensure sealing during mixing and discharge after mixing.
[0016] Preferably, the bottom of the mixing chamber is hinged to an electric cylinder via a hinge seat, and the piston rod of the electric cylinder is hinged to a sealing plate via the hinge seat, providing automated driving power for the sealing plate. The sliding of the sealing plate is controlled by the extension and retraction of the electric cylinder, thereby realizing the automated opening and closing of the discharge port.
[0017] Compared with the prior art, the beneficial effects of this utility model are:
[0018] (1) By directly integrating the screening component into the top of the sealing cover of the mixing chamber, an integrated structure of "screening-mixing" is formed. After screening, the raw material can directly enter the mixing chamber through the sealed channel, which completely eliminates the intermediate links of "manual handling after screening - transfer to the mixing chamber feed port - feeding again" in the traditional process. This effectively simplifies the production process, shortens the production cycle of a single batch, and is especially suitable for continuous batch production scenarios, which greatly improves the overall production efficiency. At the same time, the integrated structure does not require separate installation space for screening equipment. Compared with traditional separate equipment, it significantly reduces the overall footprint of the equipment, reduces the cost of occupying the production site, and is more suitable for production workshops with limited space.
[0019] (2) The qualified raw materials after screening enter the sealed mixing chamber directly through the sealed pipe between the screening seat and the sealing cover. They are not in contact with the outside air throughout the process. At the same time, the stirring process is carried out in a stable vacuum environment, which can effectively prevent air from mixing into the raw materials and forming tiny bubbles. Combined with the three-dimensional stirring effect of the spiral blades, it can ensure that the components of the ink are fully and evenly dispersed, avoiding uneven concentration of local components, and significantly improving the color consistency, adhesion and printing adaptability of the finished ink.
[0020] (3) The filter screen in the screening chamber adopts a bolt-removable fixing structure. When the filter screen is clogged or worn, it can be quickly disassembled for cleaning or replacement, which is convenient to operate. At the same time, the damper between the screening chamber and the screening seat can effectively buffer the vibration impact, reduce the vibration damage to the main structure of the equipment, extend the overall service life of the equipment, and reduce the cost of equipment maintenance and replacement parts.
[0021] (4) The opening and closing of the sealing cover is driven by an electric push rod. The electric push rod is connected to the mixing chamber and the sealing cover in both directions through the hinge seat. When it contracts, it can provide a uniform and continuous pressure force to the sealing cover, so that the sealing gasket of the sealing cover and the sealing surface of the top of the mixing chamber is precisely squeezed to form a uniform and fitting sealing effect, providing a reliable sealing foundation for the subsequent construction of the vacuum environment.

Detailed Implementation
[0028] 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 protection scope of the present utility model.
[0029] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed", "equipped with", "sleeved with", "connected", etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.
[0030] This utility model provides, for example Figure 1-5 A vacuum mixer for producing ink materials, as shown, includes:
[0031] The frame 1 serves as the supporting foundation for the entire equipment, providing a stable mounting carrier for each functional component. A mixing chamber 2 for closed mixing of ink raw materials is fixedly connected to the top of the frame 1. The mixing chamber 2 is a hollow cavity structure used to contain the ink raw materials to be mixed and provide a mixing space. A vacuum pump 20 is fixedly installed on one side of the mixing chamber 2. The suction end of the vacuum pump 20 is connected to the inside of the mixing chamber 2 through a sealed pipe to extract air from the mixing chamber 2 to create and maintain a vacuum environment, preventing air from mixing into the ink and forming bubbles during the mixing process.
[0032] A sealing cover 3 is connected to the top of the frame 1 at the position corresponding to the opening of the mixing chamber 2 via a hinge structure, and is used to seal the top opening of the mixing chamber 2. A screening component for pre-treating the input ink raw materials is integrated at the top center of the sealing cover 3. The screening component is used to remove impurities and break up clumps in the raw materials, realizing the integrated connection of raw material screening and mixing. The screening component includes a screening seat 4 and a screening chamber 5. The screening seat 4 is fixedly connected to the top center of the sealing cover 3, and has a feeding channel communicating with the mixing chamber 2 inside. The screening chamber 5 is set on the top of the screening seat 4 and is used to hold the raw materials to be screened. A vibration motor 6 is fixedly installed on the outer surface of the screening chamber 5. The vibration motor 6 acts as a vibration source to generate high-frequency vibration and transmits it to the screening chamber 5, causing the screening chamber 5 to drive the internal raw materials to vibrate. The screening of the raw materials is achieved through vibration. The qualified raw materials after screening directly enter the mixing chamber 2 through the feeding channel of the screening seat 4.
[0033] Electric push rod 7 is symmetrically arranged on both sides of the mixing chamber 2. Its two ends are respectively hinged to the mixing chamber 2 and the sealing cover 3. The extension and retraction of the piston rod of the electric push rod 7 provides driving force to push the sealing cover 3 to rotate around the hinge point, thereby realizing the opening and closing action of the opening of the mixing chamber 2. When closed, it can provide continuous pressure to the sealing cover 3 to ensure the sealing effect.
[0034] The screening seat 4 and the sealing cover 3 are connected by a sealed pipe, which is used to realize the closed transport of the raw material after screening and prevent the raw material from contacting the air. A butterfly valve is installed on the sealed pipe, which is used to control the opening and closing of the sealed pipe. It is closed during the vacuuming and stirring process of the mixing chamber 2 to ensure the sealing of the mixing chamber 2. The discharge end of the screening chamber 5 is connected to the sealed pipe by a flexible hose. The flexible hose is used to adapt to the vibration displacement of the screening chamber 5 and avoid the vibration from affecting the stability of the pipe connection.
[0035] Several dampers 8 are evenly connected between the screening chamber 5 and the screening base 4. The dampers 8 are used to buffer the vibration impact generated by the vibration motor 6, reduce the transmission of vibration to the frame 1 and the mixing chamber 2, and reduce the overall vibration loss of the equipment. A filter screen 9 is detachably installed inside the screening chamber 5. The filter screen 9 is fixed to the inner wall of the screening chamber 5 by several bolts 10. The filter screen 9 is used to intercept impurities and undissolved clumps in the raw materials. The fixing method of the bolts 10 facilitates the disassembly, cleaning or replacement of the filter screen 9 to adapt to the screening requirements of raw materials with different particle sizes.
[0036] The fixed end of the electric push rod 7 is hinged to the outer wall of the mixing chamber 2 via a hinge seat, and the telescopic end of the electric push rod 7 is hinged to the lower surface of the sealing cover 3 via a hinge seat. The hinge seat connection structure allows the electric push rod 7 to adapt to the rotation angle change of the sealing cover 3 during the telescopic process, ensuring stable transmission of driving force, and at the same time, it allows the sealing cover 3 to accurately fit with the opening surface of the mixing chamber 2 when closed, thereby improving the sealing reliability.
[0037] Two sets of symmetrically distributed hinge frames 11 are fixedly connected to the side of the mixing chamber 2 near the hinge end of the sealing cover 3. An installation gap is formed between the two sets of hinge frames 11. One end of the sealing cover 3 extends into the installation gap and is hinged to the hinge frame 11 through a pin. The hinge frame 11 provides a stable hinge fulcrum for the sealing cover 3, ensuring the coaxiality of the sealing cover 3 when rotating around the pin, and avoiding sealing failure due to misalignment.
[0038] A stirring rod 12 is horizontally arranged along the axial direction inside the stirring chamber 2. The two ends of the stirring rod 12 are rotatably connected to the side wall of the stirring chamber 2 through bearings. The bearings adopt a sealed structure to ensure the vacuum sealing of the stirring chamber 2. A spiral blade 13 is fixedly connected to the outer circumferential surface of the stirring rod 12. The spiral blade 13 is spirally distributed along the axial direction of the stirring rod 12 and is used to generate shearing, mixing and axial circulation action on the raw materials when the stirring rod 12 rotates, so as to realize the three-dimensional uniform stirring of the raw materials.
[0039] A servo motor 14 is fixedly installed on the outer wall of one end of the mixing chamber 2. The output shaft of the servo motor 14 is connected to one end of the mixing rod 12 via a coupling to provide rotational power to the mixing rod 12. The servo motor 14 can adjust its speed to adapt to the mixing process requirements of ink raw materials with different viscosities, ensuring uniform mixing while avoiding equipment overload.
[0040] The bottom center of the mixing chamber 2 protrudes downward to form a discharge shell 15, and a discharge channel communicating with the mixing chamber 2 is formed inside the discharge shell 15. Sliding grooves 16 are formed on the inner walls of the opposite sides of the discharge shell 15 in the horizontal direction. A discharge port 17 is formed at the bottom of the mixing chamber 2 corresponding to the position of the discharge shell 15. The discharge port 17 is communicating with the discharge channel. A sealing plate 19 is slidably connected between the two sets of sliding grooves 16. The size of the sealing plate 19 matches the discharge port 17 and is used to seal or open the discharge port 17 by sliding, so as to ensure the sealing performance during the mixing process and the smoothness of the discharge.
[0041] An electric cylinder 18 is hinged to the bottom of the mixing chamber 2 near the discharge shell 15 via a hinge seat. The piston rod of the electric cylinder 18 is hinged to the end of the sealing plate 19 via the hinge seat. The electric cylinder 18 serves as a drive source, and the extension and retraction of the piston rod drives the sealing plate 19 to slide along the slide groove 16, thereby realizing the automated opening and closing control of the discharge port 17, improving the ease of operation and control accuracy.
[0042] The vacuum mixer for ink material production uses a filter screen 9 with an appropriate mesh size, selected according to the particle size requirements of the ink raw materials to be processed. If the filter screen 9 needs to be replaced, the fixing bolt 10 can be unscrewed to remove the old filter screen 9, and the new filter screen 9 can be replaced. After that, the bolt 10 is tightened again to ensure that the screening accuracy meets the production requirements. After the preparation work is completed, the ink raw materials to be processed (including solid raw materials such as pigments and resin particles) are put into the screening chamber 5 in sequence according to the ratio (some liquid additives are directly poured into the mixing chamber 2). The vibration motor 6 on the surface of the screening chamber 5 is started. After the vibration motor 6 is powered on, it generates high-frequency vibration. This vibration is transmitted to the filter screen 9 inside the shell of the screening chamber 5, driving the filter screen 9 to vibrate synchronously at high frequency. Under the action of vibration, the raw materials flow along the surface of the filter screen 9. Among them, the fine particles and liquid components that meet the particle size requirements pass through the mesh of the filter screen 9, while the qualified raw materials after screening fall directly into the mixing chamber 2 through the pipe between the screening seat 4 and the sealing cover 3, realizing the seamless connection between the screening and mixing processes, without the need for manual transfer.
[0043] After the clumps of raw materials are broken up by the vibration, they can pass through the filter screen 9. Impurities, large clumps that have not been broken up, and foreign objects are trapped on the surface of the filter screen 9. (If there are signs of clogging in the filter screen 9, a brush can be used to brush the surface of the filter screen 9 as needed, which, in conjunction with the operation of the vibration motor 6, reduces the probability of clogging.) During the screening process, the damper 8 connecting the screening chamber 5 and the screening base 4 plays a key role. It can effectively absorb the impact energy generated by the vibration and prevent the vibration from being directly transmitted to the equipment frame 1 and the mixing chamber 2, thus preventing the main components of the equipment from becoming loose or fatigued. At the same time, the screening chamber 5 is connected to the feed pipe by a flexible hose, which can flexibly adapt to the vibration displacement of the screening chamber 5 and ensure that the raw materials can smoothly enter the subsequent channels after screening. After screening is completed, the vibration motor 6 is turned off.
[0044] After all raw materials have fallen into the mixing chamber 2, close the butterfly valve on the screening pipe to prevent air from entering from the screening chamber 5 during subsequent vacuuming. Start the electric push rods 7 on both sides of the mixing chamber 2. The piston rod of the electric push rod 7 retracts under the action of the drive mechanism, driving the sealing cover 3 to slowly rotate around the pin of the hinge frame 11 on one side of the mixing chamber 2 through the hinge seat until the sealing cover 3 is completely in contact with the sealing surface of the top opening of the mixing chamber 2. At this time, the sealing gasket on the edge of the sealing cover 3 can be in contact with the sealing gasket in the sealing surface of the top opening of the mixing chamber 2 to form a seal. Then start the mixing chamber. The vacuum pump 20 on one side is connected to the inside of the mixing chamber 2 through a dedicated pipe. After starting, it begins to extract air from the mixing chamber 2. The air inlet of the vacuum pipe is equipped with an anti-clogging filter 9 (to prevent dust from entering the vacuum pump 20) to block the entry of raw materials. The connecting pipe between the vacuum pump 20 and the mixing chamber 2, as well as the air inlet, are all located in the upper part of the mixing chamber 2 (away from the bottom area where the raw materials are stored). When vacuuming, the air in the upper part of the chamber is extracted first. The raw materials settle to the bottom of the chamber due to their own weight and will not come into contact with the air inlet, thus avoiding the problem of extracting raw materials when vacuuming.
[0045] During the vacuuming process, the vacuum status inside the chamber needs to be monitored in real time. Once the vacuum level reaches the production process set value, the vacuum pump 20 automatically switches to the pressure holding state to maintain a stable vacuum environment inside the chamber. This vacuum environment not only prevents air from mixing into the raw materials and forming bubbles during subsequent stirring, but also effectively isolates air from contact with easily oxidized raw materials, preventing the raw materials from oxidizing and deteriorating, and ensuring the stability of the raw material performance.
[0046] After confirming that the vacuum level inside the mixing chamber 2 is stable, the servo motor 14 at one end of the mixing chamber 2 is started. The output shaft of the servo motor 14 drives the mixing rod 12 inside the mixing chamber 2 to rotate at high speed around the bearing through the coupling. The spiral blades 13 fixed on the mixing rod 12 rotate synchronously with the mixing rod 12. The spiral blades 13 adopt a three-dimensional spiral structure design. During the rotation, on the one hand, it generates radial shearing and stirring action on the raw materials, breaking up the agglomeration of the raw materials; on the other hand, the helix angle design of the spiral structure allows the raw materials to circulate along the axis of the mixing chamber 2 during the stirring process. That is, the raw materials at the bottom are carried to the top by the spiral blades 13 and then fall from both sides, forming a comprehensive three-dimensional mixing effect, ensuring that all components such as pigments, resins, solvents and various additives can be evenly dispersed. The servo motor 14 has a speed adjustment function, which can flexibly adjust the stirring speed according to the viscosity characteristics of the raw materials and the stirring process requirements: for low viscosity raw materials, a higher speed can be used to improve stirring efficiency, while for high viscosity raw materials, the speed can be reduced to avoid excessive load on the equipment, while ensuring stirring uniformity, effectively adapting to the production needs of different types of inks. During the mixing process, the motor operating status and mixing time can be monitored in real time through the equipment control system to ensure that the process requirements are met.
[0047] After the set mixing time is reached, the servo motor 14 is turned off first. After the mixing rod 12 has completely stopped rotating, the vacuum environment in the mixing chamber 2 is slowly released through the vent valve of the vacuum pump 20 to avoid sudden pressure changes in the chamber that could cause material to splash. After vacuum release, start the electric cylinder 18 at the bottom of the mixing chamber 2. The piston rod of the electric cylinder 18 extends and pushes the sealing plate 19 to slide horizontally along the slide groove 16 in the material discharge shell 15 through the hinge seat, gradually opening the discharge port 17. The uniformly stirred ink falls into the collection container below through the discharge port 17 under its own gravity. The material discharge can be observed through the observation window. If the material discharge is not smooth, the stirring rod 12 can be started briefly to rotate at low speed to assist the material discharge. After the material discharge is completed, control the piston rod of the electric cylinder 18 to retract and drive the sealing plate 19 to reset. The sealing gasket on the sealing plate 19 fits tightly with the edge of the discharge port 17, and a reliable seal is achieved again. Then, start the electric push rod 7 to push the sealing cover 3 to rotate around the hinge frame 11 to open it, cleaning the inside of the mixing chamber 2, the spiral blade 13 and the inside of the sealing cover 3. At the same time, remove the filter screen 9 in the screening chamber 5 to clean the trapped impurities and clumps. After cleaning, reset the filter screen 9 and close the sealing cover 3 to prepare for the next batch of production.
