[0032] refer to Figures 1 to 4 This invention describes a sauce colloid emulsification feeding machine according to an embodiment of the present invention.
[0033] like Figures 1 to 4As shown, the sauce colloid emulsification feeder includes a tank 100 with a stirring chamber; multiple feeding channels 200 for supplying emulsified colloids; a premixing mechanism 300 mounted on the tank 100, with its input end connected to all feeding channels 200 and its output end connected to the stirring chamber, for preliminary mixing of the colloids; a spraying mechanism 400 mounted on the output end of the premixing mechanism 300 and extending toward the stirring chamber, for uniformly feeding the premixed colloids into the stirring chamber via the spraying mechanism 400; and a stirring mechanism 500 coaxially mounted on the tank 100 and rotatably connected to the tank 100, located within the stirring chamber, for promoting rapid mixing of the colloids.
[0034] like Figure 1 As shown, the tank 100 includes a tank body 110 and a tank cover 120, wherein the tank body 110 and the tank cover 120 enclose a stirring chamber. A stirring mechanism 500 is coaxially disposed within the stirring chamber and rotatably connected to the tank cover 120. A premixing mechanism 300 is disposed on the tank cover 120, with its input end connected to multiple feeding channels 200 and its output end connected to the stirring chamber. The premixing mechanism 300 and the tank 100 are connected via a spraying mechanism 400, with the input end of the spraying mechanism 400 connected to the premixing mechanism 300 and the other end extending into the stirring chamber. Multiple feeding channels 200 supply the adhesive material to the premixing mechanism 300, which mixes the different adhesive materials. After premixing, the spraying mechanism 400 evenly disperses the premixed adhesive material into the mixing chamber in the form of fine droplets. By increasing the contact area between the adhesive materials, the different components of the adhesive materials can be more effectively mixed and emulsified in a shorter time under the action of the mixing mechanism 500, improving emulsification efficiency and the uniformity and consistency of the emulsion. This not only reduces the burden on the mixing mechanism 500, but also avoids the problem of uneven mixing caused by directly adding the adhesive material into the emulsifier, reduces the mixing time in subsequent process steps, and improves production efficiency.
[0035] In some specific embodiments of this utility model, the premixing mechanism 300 includes: a mixing tank 310, which is disposed on the tank body 100 and has a mixing chamber. The input end of the mixing chamber is connected to the feeding channel 200, and the output end of the mixing chamber is connected to the stirring chamber; and a mixing component 320, which is disposed on the mixing tank 310 and located in the mixing chamber. The mixing component 320 is used for the preliminary mixing of different raw materials.
[0036] In some specific embodiments of this utility model, the mixing component 320 includes: a mixing shaft 321, which is coaxially disposed on the mixing tank 310 and located in the mixing chamber; a plurality of mixing rods 322, which are evenly distributed circumferentially on the mixing shaft 321 and are used to stir the raw materials; and a driving member 323, which is disposed on the mixing tank 310 and connected to the mixing shaft 321 and is used to drive the mixing shaft 321 to rotate in the mixing chamber.
[0037] like Figure 2 As shown, in this specific embodiment, the driving component 323 is a motor, which is coaxially mounted on the top of the mixing tank 310. Two feeding channels 200 are provided, symmetrically arranged on both sides of the motor, and both feeding channels 200 are interconnected with the mixing chamber. The output end of the motor is connected to a mixing shaft 321, which is coaxially mounted with the mixing chamber. Multiple mixing rods 322 are circumferentially arranged on the side wall of the mixing shaft 321. Specifically, the mixing rods 322 are L-shaped, with their shorter ends connected to the mixing shaft 321 and their longer ends extending in the same direction as the mixing shaft 321. Therefore, when the feeding channel 200 conveys the adhesive material into the mixing chamber, the driving component drives the mixing shaft 321 to rotate, and the mixing rods 322 stir and mix the adhesive materials of different components. This ensures that the raw materials of different components are fully mixed, providing a uniform and stable raw material base for subsequent processing steps, and helping to ensure the quality and consistency of the final product.
[0038] In some specific embodiments of this utility model, a collecting pipe 410 is coaxially mounted on a mixing shaft 321; a spraying pipe 420 is coaxially mounted on the collecting pipe 410, located at the end of the collecting pipe 410 opposite to the mixing shaft 321, and located inside the mixing chamber, with multiple spray holes 421 opened on the outer wall of the spraying pipe 420; and an opening and closing component is mounted on the spraying pipe 420, used to control the opening and closing of the spray holes 421.
[0039] like Figure 2As shown, a discharge port is provided on the mixing chamber, and the rotatable collection pipe 410 is installed inside the discharge port. The spray pipe 420 extends from the inlet into the mixing chamber, and multiple spray holes 421 are provided on the outer wall of the spray pipe 420. The drive assembly is connected to the collection pipe 410, and the drive component 323 is used to drive the collection pipe 410 to rotate so that the spray holes 421 can rotate and spray material. The opening and closing component is used to intermittently open the spray holes 421. Thus, the drive component 323 drives the mixing shaft 321 and the collection pipe 410 to rotate, and the rubber material in the mixing chamber enters the collection pipe 410, and then is evenly dispersed into the mixing chamber through the spray pipe 420. It should be noted that by opening or closing the opening and closing component to adjust the spray flow rate, the spray volume can be precisely controlled to ensure that the liquid can be evenly sprayed into the mixing chamber and improve the emulsification efficiency.
[0040] Specifically, the driving component is an electric valve, which is remotely controlled to open and close the spray nozzle 421 to adjust the spray flow rate of the adhesive.
[0041] In some specific embodiments of this utility model, the stirring mechanism 500 includes: a stirring shaft 510, which is coaxially arranged on the tank 100; a plurality of first stirring components 520, which are axially arranged on the stirring shaft 510 and coaxially arranged with the tank 100; the first stirring components 520 are used to shear and squeeze liquid or solid mixtures; and a plurality of second stirring components 530, which are axially arranged on the stirring shaft 510, with the first stirring components 520 and the second stirring components 530 arranged coaxially and spaced apart; the second stirring components 530 are used to prevent the emulsion from clumping.
[0042] In some specific embodiments of this utility model, the first stirring assembly 520 includes: a fixing member 521, which is fixedly sleeved on the stirring shaft 510; and a plurality of stirring plates 522, which are evenly arranged on the side wall of the fixing member 521 along the circumference, each stirring plate 522 having an angle with the stirring shaft 510, and each stirring plate 522 being arranged in the same direction.
[0043] In some specific embodiments of this utility model, the second stirring assembly 530 includes: a first fixing rod 531, which is vertically arranged on the stirring shaft 510; a second fixing rod 532, which is vertically arranged on the stirring shaft 510, and is perpendicular to the first fixing rod 531, with the second fixing rod 532 located below the first fixing rod 531; and two stirring blades 533, which are symmetrically arranged around the center of the stirring shaft 510. Each stirring blade 533 is inclined in the same direction as the stirring plate 522, and one end of each stirring blade 533 is connected to the end of the first fixing rod 531, and the other end is connected to the end of the adjacent second fixing rod 532.
[0044] like Figure 3 and Figure 4 As shown, the stirring shaft 510 extends vertically. In this specific embodiment, two first stirring components 520 and two second stirring components 530 are provided. The two first stirring components 520 and the two second stirring components 530 are spaced apart along the axial direction of the stirring shaft 510. Specifically, the first stirring component 520 includes a fixing member 521 and a plurality of stirring plates 522. The fixing member 521 is cylindrically sleeved on the stirring shaft 510. The stirring plate 522 includes a first plate and a second plate. The first plate and the second plate are perpendicular to each other and connected to form an L-shape. The length of the first plate is greater than that of the second plate. Specifically, one end of the second plate is connected to the first plate, and the other end is inclinedly disposed on the fixing member 521. In this specific embodiment, four stirring plates 522 are provided. The four stirring plates 522 are evenly disposed on the side wall of the fixing member 521 along the circumference, and the four stirring plates 522 are all inclined in the same direction. The second stirring assembly 530 includes a first fixing rod 531 and a second fixing rod 532 disposed on the stirring shaft 510, and two stirring blades 533 respectively connected to the first fixing rod 531 and the second fixing rod 532. Specifically, the first fixing rod 531 is located above the second fixing rod 532, and the first fixing rod 531 and the second fixing rod 532 are perpendicular to each other. Both stirring blades 533 are arc-shaped, with one end of the stirring blade 533 connected to one end of the first fixing rod 531 and the other end of the stirring blade 533 connected to one end of the second fixing rod 532. The two stirring blades 533 are centrally symmetrical, and the inclination direction of the two stirring blades 533 is consistent with the inclination direction of the stirring plate 522. Thus, the first stirring component 520 can effectively push the raw material from the bottom up, providing horizontal shear force during emulsification, while the second stirring component 530 can push the raw material from the side towards the center, providing spiral stirring force during emulsification. Together, they can achieve multi-directional mixing, with stirring covering every corner of the mixing chamber, making it suitable for raw materials of different types, particle sizes, and shapes.
[0045] In some specific embodiments of this utility model, the first stirring component 520 is detachably connected to the stirring shaft 510, and the second stirring component 530 is detachably connected to the stirring shaft 510. Thus, different stirring components can be used according to different adhesives to achieve the maximum emulsification efficiency.
[0046] In some specific embodiments of this utility model, the stirring mechanism 500 further includes a scraping assembly 540, which is disposed on the stirring shaft 510 and located below the first stirring assembly 520 and the second stirring assembly 530. The scraping assembly 540 is coaxially disposed with the first stirring assembly 520 and is used to remove sediment from the bottom of the stirring chamber.
[0047] In some specific embodiments of this utility model, the scraping assembly 540 includes a plurality of scraping rods 541, which are evenly distributed circumferentially on the stirring shaft 510, and the bottom of each scraping rod 541 abuts against the bottom wall of the stirring chamber.
[0048] It should be noted that insufficient emulsification or improper use of emulsifier may lead to instability of the emulsion, resulting in phase separation or precipitation. In this specific embodiment, two scraper rods 541 are symmetrically arranged at the bottom end of the rotating shaft. Specifically, the scraper rod 541 has a scraping part 5411, the cross-section of which is set as an isosceles triangle, and the midline of the cross-section of the scraping part 5411 is always perpendicular to the inner bottom wall of the tank 100, so that one side of the scraping part 5411 is always in contact with the inner bottom wall of the tank 100, thereby improving the scraping effect on the sediment on the inner bottom wall of the tank 100.
[0049] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments.
