Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of mixing devices, in particular to a vacuum paste making machine and an auxiliary mechanism thereof. Background Art
[0002] A vacuum paste machine is a key industrial equipment that integrates mixing, homogenizing, emulsifying, and degassing functions, primarily used in the toothpaste, cosmetics, pharmaceutical, and food industries. It maintains a high vacuum within a sealed container to prevent oxidation and flavor volatilization, while also removing air bubbles to improve paste density and stability. The machine features a multi-stage mixing system: slow stirring (paddle-type stirring combined with a movable scraper to eliminate residual material on the tank wall and ensure uniform heat transfer); and high-speed homogenization (using a homogenizer or colloid mill to vigorously shear the powder-liquid mixture, achieving ultrafine dispersion and emulsification).
[0003] Vacuum paste machines require a homogenizer to forcefully shear, crush, and disperse the material. A homogenizer uses a high-speed rotating rotor / stator structure (or similar design) (typically several thousand revolutions per minute) to generate extremely strong shear, impact, and turbulence. This effectively breaks up and deagglomerates agglomerated pigments (such as titanium dioxide and color powder), powdery raw materials (such as zinc oxide and talc), and other insoluble solid powders, dispersing them evenly into the liquid continuous phase. The strong shearing action overcomes the interfacial tension between the oil and water phases, breaking the immiscible oil phase (dispersed phase) into extremely small droplets (typically at the micron level), which are then evenly and stably dispersed into the water phase (continuous phase), forming a stable emulsion (O / W or W / O).
[0004] For example, the utility model patent with announcement number CN219209650U provides a vacuum paste-making machine, in which a stirring rod and stirring blades are installed on the periphery of the first rotating shaft, and spiral blades are installed on the periphery of the second rotating shaft and the third rotating shaft. Through the mutual cooperation of the first rotating shaft, the second rotating shaft and the third rotating shaft, the stirring speed of the paste can be accelerated, making the paste mixed more evenly. However, due to the large depth of the vacuum paste-making machine, the vacuum defoaming time will be prolonged, thereby affecting production efficiency. In addition, the vacuum paste-making machine requires an external homogenizer. The high-speed homogenizer will violently draw in air, generating a large number of tiny bubbles. These bubbles are difficult to completely remove after the vacuum is re-established, affecting the product appearance and foam performance. Summary of the Invention
[0005] The invention provides a vacuum paste making machine and an auxiliary mechanism thereof, so as to solve the problems of long vacuum defoaming time and low defoaming efficiency in the existing vacuum paste making machine.
[0006] The present invention employs the following technical solution: an auxiliary mechanism of the vacuum paste making machine includes a fixed disk, a rotating disk, a homogenizing disk, and an adjustment mechanism. The fixed disk is vertically disposed and defines a mounting groove and an inlet and an outlet connected to the mounting groove. The rotating disk and the homogenizing disk are coaxial with the fixed disk. The rotating disk is rotatably disposed within the mounting groove.
[0007] The homogenizing disc is mounted on a fixed disc and blocks the mounting groove. A homogenizing block is installed on the disc, with a gap between the block and the rotating disc. Material enters the mounting groove from the inlet, is crushed after passing through the gap, and is discharged from the outlet after defoaming.
[0008] The adjustment mechanism includes a rotating ring, a rotating rod, a Hall effect element, and a magnet. The rotating ring is rotatably mounted on the homogenizing disk, coaxially with the disk, and located within a mounting groove. The rotating rod is fixedly connected to the rotating ring and radially disposed along the rotating ring. When the bubble content in the material exceeds a first preset value, the bubbles drive the rotating rod to rotate. Furthermore, when the rotating disk speed exceeds a second preset value, the material drives the rotating rod to rotate.
[0009] A Hall effect element is mounted on the homogenizing disk. A magnet is located within the rotating ring. The magnet and Hall effect element work together to generate an electrical signal. The magnitude of the signal is proportional to the angle of the rotating ring relative to the homogenizing disk in the forward direction. Forward rotation occurs when the rotating ring and the rotating disk rotate in the same direction. This electrical signal controls the rotating disk's speed, and the magnitude of the signal is inversely proportional to the speed to ensure effective defoaming.
[0010] Furthermore, an auxiliary mechanism of a vacuum paste making machine also includes a bracket and a drive mechanism, wherein a fixed disk is fixedly mounted on the bracket. The drive mechanism includes a first motor, a pulley, and a transmission belt. A rotating shaft is fixedly mounted on the turntable, and the rotating shaft and the turntable are arranged coaxially. The pulley is fixedly mounted on the rotating shaft, and the pulley and the rotating shaft are arranged coaxially. The first motor is fixedly mounted on the bracket, and a rotating wheel is fixedly mounted on the output shaft of the first motor. The rotating wheel and the pulley are connected by a transmission belt. An electrical signal is used to control the rotational speed of the first motor, and thus the rotational speed of the turntable.
[0011] Furthermore, a first fixed block and a second fixed block are fixedly mounted on the homogenizing disk. The first fixed block, the second fixed block, and the homogenizing block are distributed along the circumference of the homogenizing disk. A discharge space connected to the outlet is formed between the first and second fixed blocks. A feed space connected to the inlet is formed between the second fixed block and the homogenizing block. A reaction space for material reaction is formed between the homogenizing block and the first fixed block. The discharge space, the feed space, and the reaction space are interconnected. The rotating rod is located within the reaction space.
[0012] Furthermore, a guide arc is formed on the homogenizing block on a side near the turntable, with the concave surface of the guide arc facing the turntable. Along the circumference of the turntable, the guide arc is defined by a first side and a second side. Furthermore, along the direction of rotation of the turntable, the first side of the guide arc is located in front of the second side and is higher than the second side. The liquid level within the reaction space is flush with the top of the first side of the guide arc.
[0013] Furthermore, a fixed sleeve is fixedly provided on the homogenizing disk, and the fixed sleeve and the homogenizing disk are coaxially arranged. The rotating ring is rotatably arranged in the fixed sleeve. The rotating ring and the fixed sleeve are connected by a torsion spring.
[0014] Furthermore, the fixed sleeve defines a first arc groove, which is coaxially disposed with the fixed sleeve and located within the reaction space. The rotating rod is rotatably disposed within the first arc groove. The first arc groove has first and second ends, respectively, along the circumference of the rotating ring and aligns with the direction of rotation of the turntable. The first end of the first arc groove is located forward of the second end. The first arc groove serves to limit the rotation angle of the rotating rod.
[0015] Furthermore, the bottom of the first arc groove is an inclined surface, and the first end is higher than the second end. The first end of the first arc groove is flush with the first side of the guide arc surface.
[0016] The swivel rod comprises a connecting tube and a connecting rod, both of which are arranged radially along the swivel. The connecting tube is fixedly connected to the swivel, and the lower side of the connecting tube is open. The connecting rod is rotatably mounted within the connecting tube, and a connecting post is fixedly mounted in the middle of the connecting rod. The connecting post is arranged tangentially to the swivel and rotatably mounted on the connecting tube. Compression springs are fixedly mounted at each end of the connecting rod, and the compression springs are fixedly connected to the connecting tube. The lower side of the connecting rod abuts against the bottom of the first arc groove.
[0017] The portion of the first arc groove near the first end is the first section, and the portion of the first arc groove near the second end is the second section. When the connecting rod is in the first section, it is positioned horizontally. When the connecting rod is in the second section, the end of the connecting rod near the swivel is higher than the end of the connecting rod away from the swivel, thereby flattening material that has accumulated on the circumferential wall of the mounting groove and above the central area due to centrifugal force.
[0018] A vacuum ointment making machine includes an auxiliary mechanism of the vacuum ointment making machine, an ointment making cylinder, a delivery pump and two ointment delivery pipes: The paste-making tank is vertically mounted, with one paste-making pipe connecting the tank to the inlet and another to the outlet. A transfer pump circulates the material between the tank and the mounting groove.
[0019] Furthermore, the vacuum paste making machine also includes a vacuum pump. A vacuum tube connected to the mounting groove is provided on the homogenizing disk. The vacuum pump is connected to the vacuum tube via an air pipe, and the vacuum pump is connected to the paste making cylinder via another air pipe. The vacuum pump is used to maintain a vacuum state inside the paste making cylinder and the mounting groove.
[0020] Furthermore, the vacuum paste making machine also includes a stirring mechanism, which includes a second motor and a stirring shaft. The second motor is fixedly mounted on the paste making tank, and the stirring shaft is coaxially arranged with the paste making tank and fixedly connected to the output shaft of the second motor. A plurality of stirring plates are provided on the peripheral wall of the stirring shaft.
[0021] The beneficial effects of the present invention are as follows: a vacuum paste making machine of the present invention, through the provided adjustment mechanism, the material enters the installation circular groove from the entrance, and under the high-speed rotation of the turntable, the material is crushed after passing through the gap between the homogenizing block and the turntable, and the crushed material rotates with the turntable, and the crushed material is defoamed in the installation circular groove, and finally the material is discharged from the outlet.
[0022] When the volume of bubbles entering the reaction chamber exceeds a predetermined value, the bubbles push the rotating rod in the forward direction. This in turn drives the rotating ring and magnet to rotate synchronously. The magnet and Hall effect element work in concert. The more bubbles there are, the greater the rotating ring's angle of rotation, and the stronger the electrical signal generated by the interaction between the magnet and Hall effect element. This electrical signal controls the speed of the turntable, slowing it down and extending the material's residence time within the mounting groove, ensuring effective defoaming.
[0023] When the turntable speed exceeds the second preset value, under the action of centrifugal force, the material is thrown onto the peripheral wall of the installation circular groove. At the same time, the material thrown onto the peripheral wall of the installation circular groove pushes the rotating rod to rotate forward, and the speed of the turntable gradually decreases, further ensuring the defoaming effect.

DETAILED DESCRIPTION
[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts are within the scope of protection of the present invention.
[0028] Reference Figures 3 to 12 As shown, an auxiliary mechanism for a vacuum paste making machine provided by an embodiment of the present invention includes a fixed plate 502, a rotating plate 506, a homogenizing plate 501, and an adjustment mechanism. The fixed plate 502 is vertically arranged and has a mounting groove 510 coaxial with the fixed plate 502, as well as an inlet and an outlet connected to the mounting groove 510. The rotating plate 506 and the homogenizing plate 501 are both coaxial with the fixed plate 502. The rotating plate 506 is rotatably mounted within the mounting groove 510.
[0029] Homogenizing disk 501 is fixed to fixed disk 502 and blocks mounting groove 510. Homogenizing block 511 is fixed to homogenizing disk 501, with a gap between block 511 and rotating disk 506. Material enters mounting groove 510 from the inlet. Rotating disk 506 rotates the material, causing it to pass through the gap and become broken. The material is then discharged from the outlet after defoaming.
[0030] The adjustment mechanism includes a rotating ring 610, a rotating rod, a Hall effect element 602, and a magnet 604. The rotating ring 610 is rotatably mounted on the homogenizing disk 501, coaxially with the homogenizing disk 501, and located within the mounting groove 510. The rotating rod is fixedly connected to the rotating ring 610 and radially disposed along the rotating ring 610. When the bubble content in the material exceeds a first preset value, the bubbles drive the rotating rod to rotate. Similarly, when the rotation speed of the rotating disk 506 exceeds a second preset value, the material drives the rotating rod to rotate.
[0031] Hall effect element 602 is fixed to homogenizing disk 501. Magnet 604 is fixed within rotating ring 610. Magnet 604 and Hall effect element 602 interact with each other. When magnet 604 rotates, Hall effect element 602 senses the change in its magnetic field and generates an electrical signal. The magnitude of this electrical signal is proportional to the angle of rotation of rotating ring 610 relative to homogenizing disk 501 in the forward direction. Rotating ring 610 rotates in the same direction as rotating disk 506, meaning it rotates in the forward direction. This electrical signal controls the rotation speed of rotating disk 506, with the magnitude of the electrical signal inversely proportional to the rotation speed to ensure effective defoaming.
[0032] The material enters the installation circular groove 510 from the entrance. Under the high-speed rotation of the turntable 506, the material passes through the gap between the homogenizing block 511 and the turntable 506 and is crushed. The crushed material rotates with the turntable 506, and the crushed material is defoamed in the installation circular groove 510. Finally, the material is discharged from the outlet.
[0033] When the amount of bubbles entering the material within reaction space 516 exceeds a first preset value, the bubbles push the rotating rod in the forward direction. The rotating rod drives the rotating ring 610 and magnet 604 to rotate synchronously. Magnet 604 and Hall element 602 cooperate with each other. The more bubbles there are, the greater the rotation angle of rotating ring 610, and the larger the electrical signal generated by the interaction between magnet 604 and Hall element 602. This electrical signal controls the rotation speed of turntable 506, reducing it, thereby extending the residence time of the material within mounting groove 510 and ensuring effective defoaming.
[0034] When the rotation speed of the turntable 506 exceeds the second preset value, under the action of centrifugal force, the material is thrown onto the peripheral wall of the mounting circular groove 510. At the same time, the material thrown onto the peripheral wall of the mounting circular groove 510 pushes the rotating rod to rotate forward, and the speed of the turntable 506 gradually decreases, further ensuring the defoaming effect.
[0035] In this embodiment, an auxiliary mechanism of a vacuum paste making machine further includes a bracket 110 and a drive mechanism, wherein a fixed disk 502 is fixedly mounted on the bracket 110. The drive mechanism includes a first motor 400, a pulley 505, and a transmission belt. A rotating shaft 504 is fixedly mounted on the turntable 506, and the rotating shaft 504 and the turntable 506 are coaxially arranged. The pulley 505 is fixedly mounted on the rotating shaft 504, and the pulley 505 and the rotating shaft 504 are coaxially arranged. The first motor 400 is fixedly mounted on the bracket 110, and a rotating wheel is fixedly mounted on the output shaft of the first motor 400, and the rotating wheel and the pulley 505 are connected by a transmission belt. An electrical signal is used to control the speed of the first motor 400, and thereby the speed of the turntable 506. The first motor 400 is driven, and the first motor 400 drives the pulley 505 to rotate via the transmission belt, which in turn drives the turntable 506 to rotate via the rotating shaft 504.
[0036] In this embodiment, a first fixing block 512 and a second fixing block 513 are fixedly mounted on the homogenizing disk 501. The first fixing block 512, the second fixing block 513, and the homogenizing block 511 are distributed along the circumference of the homogenizing disk 501. A discharge space 514 communicating with the outlet is formed between the first fixing block 512 and the second fixing block 513. A feed space 515 communicating with the inlet is formed between the second fixing block 513 and the homogenizing block 511. A reaction space 516 for material reaction is formed between the homogenizing block 511 and the first fixing block 512. The discharge space 514, the feed space 515, and the reaction space 516 are interconnected. A rotating rod is located within the reaction space 516.
[0037] The material enters the feed space 515 from the entrance. Under the high-speed rotation of the turntable 506, the material enters the reaction space 516 through the gap between the homogenizing block 511 and the turntable 506. Then, the material enters the discharge space 514 and is discharged from the paste making cylinder 100 from the outlet.
[0038] In this embodiment, a guide arc 517 is provided on the side of the homogenizing block 511 near the turntable 506, with the concave surface of the guide arc 517 facing the turntable 506. Along the circumference of the turntable 506, the guide arc 517 is defined by a first side and a second side. Furthermore, as the turntable 506 rotates, the first side of the guide arc 517 is located in front of the second side and is higher than the second side. The liquid level within the reaction space 516 is flush with the top of the first side of the guide arc 517.
[0039] The material in the reaction space 516 is spread flat on the turntable 506 under the action of the second side of the guide arc surface 517. The thickness of the material is small, which reduces the distance for bubbles to float up and improves the defoaming efficiency.
[0040] In this embodiment, a fixing sleeve 520 is fixedly mounted on the homogenizing disk 501. The fixing sleeve 520 and the homogenizing disk 501 are coaxially arranged. A rotating ring 610 is rotatably mounted in the fixing sleeve 520. The rotating ring 610 and the fixing sleeve 520 are connected by a torsion spring 603.
[0041] When the rotating rod and the rotating disk 506 rotate in the same direction, the torsion spring 603 stores force. Afterwards, under the action of the torsion spring 603, the rotating rod is reset, and the rotating rod and the rotating disk 506 rotate in opposite directions.
[0042] In this embodiment, the fixing sleeve 520 defines a first arcuate groove 521. The first arcuate groove 521 and the fixing sleeve 520 are coaxially disposed and located within the reaction space 516. The rotating rod is rotatably disposed within the first arcuate groove 521. The first arcuate groove 521 has a first end and a second end along the circumference of the rotating ring 610, and extends in the direction of rotation of the rotating disk 506. The first end of the first arcuate groove 521 is located in front of the second end. The first arcuate groove 521 serves to limit the rotation angle of the rotating rod.
[0043] When the rotating rod rotates from the first end to the second end of the first arc slot 521, the magnet 604 and the Hall element 602 cooperate to generate an electrical signal that gradually increases, and the electrical signal controls the rotation speed of the rotating disk 506 to gradually decrease. When the rotating rod rotates from the second end to the first end of the first arc slot 521, the magnet 604 and the Hall element 602 cooperate to generate an electrical signal that gradually decreases, and the electrical signal controls the rotation speed of the rotating disk 506 to gradually increase.
[0044] In this embodiment, the bottom of the first arc groove 521 is an inclined surface, and the first end is higher than the second end. The first end of the first arc groove 521 is flush with the first side of the guide arc surface 517.
[0045] The rotating rod includes a connecting tube 600 and a connecting rod 601, both of which are arranged along the radial direction of the rotating ring 610. The connecting tube 600 and the rotating ring 610 are fixedly connected, and the lower side of the connecting tube 600 is open. The connecting rod 601 is rotatably arranged in the connecting tube 600, and a connecting column 605 is fixedly arranged in the middle of the connecting rod 601. The connecting column 605 is arranged along the tangent direction of the rotating ring 610 and is rotatably arranged on the connecting tube 600. Compression springs 607 are fixedly arranged at both ends of the connecting rod 601, and the compression springs 607 are fixedly connected to the connecting tube 600. The lower side of the connecting rod 601 abuts against the bottom of the first arc groove 521.
[0046] The portion of the first arc groove 521 near the first end is the first portion, and the portion of the first arc groove 521 near the second end is the second portion. When the connecting rod 601 is in the first portion, it is positioned horizontally. When the connecting rod 601 is in the second portion, the end of the connecting rod 601 near the swivel 610 is higher than the end of the connecting rod 601 away from the swivel 610, thereby flattening material that has accumulated on the peripheral wall of the mounting groove 510 and above the central area due to centrifugal force.
[0047] Reference Figure 1 、 2 As shown in Figure 13, a vacuum paste making machine includes the auxiliary mechanism of the above-mentioned vacuum paste making machine, and also includes a paste making cylinder 100, a delivery pump, and two paste delivery tubes 200. The paste making cylinder 100 is arranged vertically, and one paste delivery tube 200 connects the paste making cylinder 100 to the inlet. The other paste delivery tube 200 connects the paste making cylinder 100 to the outlet. The delivery pump is used to circulate the material in the paste making cylinder 100 and the mounting groove 510.
[0048] In this embodiment, a vacuum paste making machine further includes a vacuum pump 300. A vacuum tube 503 is provided on a homogenizing disk 501 and communicates with a circular mounting groove 510. The vacuum pump 300 is connected to the vacuum tube 503 via an air pipe, and the vacuum pump 300 is connected to the paste making cylinder 100 via another air pipe. The vacuum pump 300 is used to maintain a vacuum state inside the paste making cylinder 100 and the circular mounting groove 510.
[0049] In this embodiment, a vacuum paste making machine further includes a stirring mechanism comprising a second motor 101 and a stirring shaft 102. The second motor 101 is fixedly mounted on the paste making tank 100. The stirring shaft 102 is coaxially disposed with the paste making tank 100 and is fixedly connected to the output shaft of the second motor 101. The stirring shaft 102 is provided with a plurality of stirring plates on its circumferential wall. When the second motor 101 is activated, the stirring shaft 102 stirs the material.
[0050] Working process: In the initial state, the connecting rod 601 is in the first part and the connecting rod 601 is set horizontally.
[0051] The material is placed into the paste-making tank 100, and the second motor 101 is activated, stirring the material via the stirring shaft 102. The vacuum pump 300 is activated, creating a vacuum in the paste-making tank 100 and the mounting groove 510. The transfer pump is activated, pumping the material into the mounting groove 510 through the inlet. Simultaneously, the first motor 400 is driven, which drives the pulley 505 via the transmission belt, which in turn drives the turntable 506 via the rotating shaft 504.
[0052] The material enters the feed space 515 from the inlet. As the turntable 506 rotates at high speed, the material passes through the gap between the homogenizing block 511 and the turntable 506 and enters the reaction space 516, where it is crushed. While in the reaction space 516, the mounting groove 510 is in a vacuum state, removing any bubbles from the material. Simultaneously, the material in the reaction space 516 is spread flat on the turntable 506 by the second side of the guide arc 517. This reduces the thickness of the material, reduces the distance bubbles have to float, and improves defoaming efficiency. The material then enters the discharge space 514 and exits the paste-making cylinder 100 through the outlet.
[0053] When the amount of bubbles entering the reaction space 516 exceeds a first predetermined value, the bubbles push the rotating rod to rotate, causing the rotating rod and the rotating disk 506 to rotate in the same direction. The rotating rod drives the rotating ring 610 and the magnet 604 to rotate synchronously. The magnet 604 and the Hall element 602 cooperate with each other.
[0054] The more bubbles there are, the larger the rotation angle of the rotating ring 610, and the larger the electrical signal generated by the cooperation between the magnet 604 and the Hall element 602. The electrical signal controls the rotation speed of the first motor 400, causing the rotation speed of the first motor 400 to decrease, thereby reducing the rotation speed of the turntable 506, thereby extending the residence time of the material in the reaction space 516 and ensuring the defoaming effect.
[0055] After the bubbles are reduced, the rotating rod is reset under the action of the torsion spring 603, and the rotating rod and the rotating disk 506 rotate in opposite directions, and the speed of the rotating disk 506 increases.
[0056] When the rotation speed of the turntable 506 exceeds the second preset value, the material is thrown onto the peripheral wall of the installation circular groove 510 under the action of centrifugal force, and the thickness of the material on the peripheral wall of the installation circular groove 510 is greater than the thickness of the middle part of the installation circular groove 510.
[0057] The material thrown onto the walls of the mounting groove 510 simultaneously drives the rotating rod, causing it and the turntable 506 to rotate in the same direction. As the rotating rod rotates from the first end of the first arc groove 521 to the second end, the end of the connecting rod 601 closest to the rotating ring 610 gradually rises upward. Driven by the connecting post 605, the end of the connecting rod 601 farther from the rotating ring 610 moves downward, flattening the material that has been thrown onto the walls of the mounting groove 510 due to centrifugal force and that is higher than the center of the mounting groove 510. This ensures a uniform thickness of material within the mounting groove 510, further facilitating defoaming. During this process, the speed of the turntable 506 decreases.
[0058] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
