[0002] Instant noodles and other foods often come with a sauce packet. The packet contains a semi-solidified sauce. This sauce can be eaten with noodles or other items to enhance the flavor.

[0003] The sauce packet can be formed in the following manner: after one side of the envelope is sealed, the sauce is injected into the half-sealed envelope using a feeding device, and then the other side of the envelope is sealed.

[0004] In actual applications, sauce is often trapped in the sealing area of the sauce bag. This not only affects the appearance of the sauce bag, but also causes leakage during the bag cutting process, affecting food safety.

[0005] However, using the existing method to prevent sauce from being caught, the sauce-catching rate is still high. Utility Model Content

DETAILED DESCRIPTION

[0032] Figure 1 This is a structural diagram of an existing blanking device. Figure 1 The unloading device may include a material conveying pipe 11 having a sauce injection port 11a and a sauce outlet 11b. The sauce enters the material conveying pipe 11 through the sauce injection port 11a and is injected into the membrane through the sauce outlet 11b. The sauce outlet 11b of the material conveying pipe 11 is typically provided with a silicone nozzle 12 that fits over the sauce outlet 11b. A circular hole is provided below the silicone nozzle 12, through which the sauce in the material conveying pipe 11 can be injected into the membrane.

[0033] Currently, to prevent sauce from getting stuck in the sealed area of the film, after partially injecting the sauce into the film, the sauce is usually sucked back at the sauce injection port 11a to prevent the sauce from dripping from the sauce outlet 11b onto the sealed area of the film and causing sauce to get stuck. The sauce injection and sucking back are performed alternately until all the sauce is injected.

[0034] In another scenario, during hot filling (filling temperature 65°C to 85°C), when the sauce is unsolidified and highly fluid, coupled with the impact of the sauce, it will splash back onto the sealing area of the film, thus causing sauce to be trapped after the film is sealed.

[0035] Therefore, by adopting the above scheme, the sauce-adding rate is still relatively high.

[0036] To address this problem, the present invention provides a material discharge device, in which a material outlet sealing tube is provided in the material conveying pipe of the material discharge device. Compared with the back-suction method, the material outlet can be closed more quickly and timely through the material outlet sealing tube, thereby better preventing the sauce at the material outlet from dripping onto the horizontal sealing area and forming sauce jam, thereby further reducing the probability of sauce jam.

[0037] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0038] Reference Figure 2 The embodiment of the present invention provides a material discharge device, which may include: a material conveying pipe 21 and a material port blocking pipe 22.

[0039] The material conveying pipe 21 has a material injection port 21a and a material outlet 21b;

[0040] and a material port blocking tube 22 , at least a portion of which can extend into the material conveying tube 21 and move within the material conveying tube 21 ;

[0041] The material port blocking tube 22 moves in the material conveying pipe 21 in a direction away from the material outlet 21b to open the material outlet 21b; or the material port blocking tube 22 moves in the material conveying pipe 21 in a direction close to the material outlet 21b to close the material outlet 21b.

[0042] In a specific implementation, the dimensions of the material conveying pipe 21 and the material port blocking pipe 22 can be set so that the material port blocking pipe 22 can move freely in the material conveying pipe 21 without hindering the flow of material. Specifically, the material port blocking pipe 22 moves along the axial direction of the material conveying pipe 21 to open or close the material outlet 21b. The material port blocking pipe 22 can be completely located in the material conveying pipe 21, and the movement of the material port blocking pipe 22 in the material conveying pipe 21 can be controlled by an external force. The material port blocking pipe 22 can also be partially located in the material conveying pipe 21, so that the movement of the material port blocking pipe 22 in the material conveying pipe 21 is controlled by the portion of the material port blocking pipe 22 exposed outside the material conveying pipe 21.

[0043] When the material port blocking tube 22 moves away from the material outlet 21b, the material outlet 21b is opened, and the material entering the material conveying pipe 21 through the material injection port 21a can be ejected from the material outlet 21b. When the material port blocking tube 22 moves toward the material outlet 21b, the material outlet 21b is closed, and the material entering the material conveying pipe 21 through the material injection port 21a stops being ejected. This can timely block the flow of material, prevent the material from dripping onto the transverse sealing area of the film due to failure to block the material in time, and thus reduce the probability of sauce inclusion.

[0044] In a specific embodiment, the material conveying pipe 21 is in the shape of a hollow tube. The material conveying pipe 21 may include: a horizontal material conveying pipe body 211 and a vertical material conveying pipe body 212 that are connected to each other. One end of the horizontal material conveying pipe body 211 serves as the material injection port 21a, and the material outlet 21b is located on the vertical material conveying pipe body 212.

[0045] In a specific implementation, the transverse material conveying pipe 211 and the longitudinal material conveying pipe 212 are connected and form a "7" shape. Under a certain thrust, the material is injected into the transverse material conveying pipe 211 from the material injection port 21a, and flows into the longitudinal material conveying pipe 212, and then ejected downward along the longitudinal material conveying pipe 212 under the action of gravity (such as Figure 2 The material port blocking tube 22 at least partially extends into the longitudinal material conveying tube body 212 and is movable within the longitudinal material conveying tube body 212 .

[0046] In a specific implementation, the material outlet 21b can be provided at one end of the longitudinal material conveying pipe 212. Accordingly, the diameter of the longitudinal material conveying pipe 212 can be gradually reduced from the transverse material conveying pipe 211 toward the material outlet 21b, and the material port blocking pipe 22 can be provided with only the longitudinal material port blocking pipe.

[0047] Thus, when the material port blocking tube 22 moves away from the material outlet 21b, the material flowing into the longitudinal material conveying pipe body 212 can be ejected from one end of the longitudinal material conveying pipe body 212. When the material port blocking tube 22 moves toward the material outlet 21b, the material outlet 21b can be closed, preventing the ejection of material.

[0048] However, the inventors have found that when the material outlet 21b is set at one end of the longitudinal material conveying pipe 212, the impact force of the material on the envelope is relatively strong when it is sprayed out, which will cause obvious material splashing back, thereby increasing the probability of sauce inclusion.

[0049] To this end, in one embodiment of the present invention, the material outlet 21b is set on the side wall of the longitudinal material conveying tube body 212. At this time, the impact force of the material on the envelope will be significantly reduced during the process of the material being ejected from the side wall of the longitudinal material conveying tube body 212, thereby reducing the material splashing back and further reducing the probability of sauce inclusion.

[0050] Accordingly, in one embodiment of the present invention, the material port plugging tube 22 may include: a plugging tube body 221 and a plugging head 222 that are interconnected. The plugging tube body 221 and the plugging head 222 are located within the longitudinal material conveying tube body 212. The plugging tube body 221 extends along the axis of the longitudinal material conveying tube body 212, and the plugging head 222 is inclined toward one side of the longitudinal material conveying tube body 212. Furthermore, the included angle between the plugging head 222 and the axis of the plugging tube body 221 is an obtuse angle.

[0051] Specifically, the longitudinal material conveying pipe 212 is divided into a falling zone, a buffer zone, and a switching zone along the direction of material drop. The diameter of the falling zone is larger than that of the buffer zone, which in turn is larger than that of the switching zone. The blocking pipe 221 drives the blocking head 222 to move along the sidewall of the longitudinal material conveying pipe 212 in the switching zone to open or close the material outlet 21b. Material falling from the falling zone of the longitudinal material conveying pipe 212 first impacts the outer surface of the curved pipe 222 before being ejected from the material outlet 21b.

[0052] In one embodiment, in order to further improve the stability of the movement of the material port blocking tube 22, thereby improving the reliability of the opening and closing material conveying pipe, as shown in FIG. Figure 3 As shown, the inner diameter of the switch zone can be set to be substantially equal to the maximum outer diameter of the curved tube body 222 in a direction perpendicular to the transverse material conveying tube body 211. For example, the inner diameter of the switch zone can be set to range from 8 mm to 14 mm. This allows the sidewalls of the sealing tube body 221 to conform to the sidewalls of the longitudinal material conveying tube body 212, thereby ensuring the movement path of the material port sealing tube 22, preventing movement deviation of the material port sealing tube 22, and improving the efficiency of closing the material outlet.

[0053] In a specific implementation, an angle α is set between the plugging head 222 and the longitudinal material port plugging tube body 221 (e.g. Figure 2 As shown in the figure, the angle is obtuse, which can change the direction of material spraying to spraying from the obliquely downward side wall. Compared with vertical downward spraying, it can further reduce the impact force of the material on the envelope, thereby reducing material splashing back and further reducing the probability of sauce inclusion.

[0054] In a specific implementation, the angle between the curved tube body 222 and the longitudinal material port blocking tube body 221 can range from 150° to 175°. Preferably, the angle between the curved tube body 222 and the longitudinal material port blocking tube body 221 can be set to 170°. In this case, the material splashback can be minimized without affecting the material spraying amount, thereby reducing the probability of sauce inclusion.

[0055] In one embodiment of the present invention, referring to Figure 2 and Figure 3 The material port blocking tube 22 has an air inlet 22a and an air outlet 22b. The air inlet 22a is located above the material conveying pipe 21, and the air outlet 22b is located at one end of the material port blocking tube 22 close to the material outlet 21b.

[0056] At this time, the material port blocking tube 22 is in a hollow tubular shape. When the material port blocking tube 22 is close to the material outlet 21b, air can be blown into the material port blocking tube 22 through the air inlet 22a, and the gas is ejected from the air outlet 22b (as shown in FIG. Figure 2 and Figure 3 The remaining material at the material outlet 21b can be blown away, thereby cleaning the remaining material at the material outlet 21b and preventing the remaining material at the material outlet 21b from dripping into the sealing area to form jam, thereby further reducing the probability of jam.

[0057] In a specific implementation, the air inlet 22a can have a certain length and extend to one side of the material port blocking tube 22 to facilitate blowing. In one embodiment, air can be blown into the material port blocking tube 22 manually through the air inlet 22a.

[0058] In other embodiments, the blanking device may further include: an air blowing component, which is used to blow air into the material port sealing tube 22 through the air inlet 22a, thereby reducing the workload of manual blowing.

[0059] Specifically, the pressure of the gas blown into the material port sealing tube 22 by the air blowing assembly can be controlled to ensure the cleaning effect of residual material at the material outlet 21b, so that the residual material at the material outlet 21b can be blown into the envelope without causing back splashing. Specifically, the pressure of the gas blown into the material port sealing tube 22 by the air blowing assembly can be controlled to be between 1.5 kPa and 2.5 kPa. For example, the pressure of the gas blown into the material port sealing tube 22 by the air blowing assembly is 2 kPa.

[0060] In some embodiments, when the material port sealing tube 22 is close to the material outlet 21b, the air outlet 22b can be controlled to abut against the inside of the material outlet 21b, thereby closing the material outlet 21b. In this case, the outer diameter of the air outlet 22b can be set to be larger than the inner diameter of the material outlet 21b, thereby closing the material outlet 21b from the inside of the material outlet 21b and preventing the material from being ejected from the material outlet 21b.

[0061] In some embodiments, reference Figure 4 When the material port blocking tube 22 is close to the material outlet 21b, the gas outlet 22b can be controlled to extend from the inside of the material outlet 21b, and the outer surface of the gas outlet 22b can contact the inner surface of the material outlet 21b. In this way, the gas outlet 22b fills the material outlet 21b, thereby preventing the material from being ejected from the material outlet 21b. In this case, the outer diameter of the gas outlet 22b can be set to be substantially equal to the inner diameter of the material outlet 21b.

[0062] In some embodiments, to enhance the sealing effect of material outlet 21b, a first sealing ring can be provided at gas outlet 22b. The material of the first sealing ring can be silicone. The first sealing ring can be fitted over gas outlet 22b and surround it. Thus, when material port sealing tube 22 is close to material outlet 21b, the presence of the first sealing ring ensures a tighter contact between gas outlet 22b and material outlet 21b, thereby enhancing the sealing effect of material outlet 21b and preventing material from being ejected from the gap between gas outlet 22b and material outlet 21b.

[0063] In a specific implementation, the diameter of the material outlet 21b ranges from 5 mm to 10 mm, and the diameter of the air outlet 22b can be larger than the diameter of the material outlet 21b, or can be equal to or slightly smaller than the diameter of the material outlet 21b.

[0064] In one embodiment of the present invention, referring to Figure 4 and Figure 5 The unloading device may further include: a driving component 23 , wherein the driving component 23 is connected to the material port blocking tube 22 and is used to drive the material port blocking tube 22 to move in the material conveying pipe 21 .

[0065] By providing the driving assembly 23 , the movement of the material port blocking tube 22 can be automatically controlled, thereby reducing the workload of manual operation and improving the material discharge efficiency.

[0066] In a specific implementation, the driving component 23 can be any component that can drive the material port blocking tube 22 to move along the inner wall of the material conveying pipe 21. For example, the driving component 23 can be set as a cylinder, and the output end of the cylinder can be connected to the material port blocking tube 22, thereby driving the material port blocking tube 22 to move.

[0067] In one embodiment of the present invention, referring to Figures 2 to 5 A second sealing ring 24 is provided at the connection between the material port blocking tube 22 and the material conveying tube 21. The second sealing ring 24 ensures that the material conveying tube 21 is sealed during the movement of the material port blocking tube 22 inside the material conveying tube 21, thereby preventing material from being ejected from the connection between the material port blocking tube 22 and the material conveying tube 21 and preventing the gap between the material port blocking tube 22 and the material conveying tube 21 from affecting the material ejection effect.

[0068] In a specific implementation, a second sealing ring 24 can be provided on the through-hole of the longitudinal material conveying pipe, which is used to extend into the material port sealing pipe 22. The material of the second sealing ring 24 can be silicone. The second sealing ring 24 surrounds the through-hole of the longitudinal material conveying pipe and forms an interference fit with the material port sealing pipe 22, thereby sealing the material conveying pipe when the material port sealing pipe 22 moves.

[0069] In a specific implementation, the material of the material conveying pipe 21 and the material port blocking pipe 22 can be made of corrosion-resistant and high-temperature resistant materials, such as stainless steel. The material includes but is not limited to instant noodle sauce, and can also be other semi-solidified materials.

[0070] use Figure 1 The feeding device shown in FIG has a sauce inclusion rate of about 0.5% when injecting sauce into the film under normal temperature, and about 2% when injecting sauce into the film under hot filling conditions. However, with the solution of the present utility model, the sauce inclusion rate is as low as 0.1% when injecting sauce into the film under hot filling conditions.

[0071] As can be seen from the foregoing, the material discharge device of the present invention can be used to seal the material outlet using a material port blocking tube, eliminating the need for back-sucking. This prevents sauce jams caused by untimely back-sucking, thereby reducing the probability of sauce jams. Furthermore, the material port blocking tube is provided with an air inlet and an air outlet, allowing air to be directed into the material port blocking tube through the air inlet, preventing excess sauce from dripping and causing sauce jams, further reducing the probability of sauce jams. Positioning the material outlet on the sidewall of the material conveying tube can also change the direction of material discharge, further reducing the probability of sauce jams.

[0072] The present invention also provides a blanking system, which may include:

[0073] The sealing device and the blanking device of any one of the above embodiments, wherein the sealing device can be used to perform a sealing operation on the envelope, and the blanking device is used to inject material into the semi-sealed envelope.

[0074] Specifically, for example, if the material is instant noodle sauce, the sealing device can seal the lower side of the envelope to form a semi-sealed envelope. At this point, the feeding device can inject the sauce into the semi-sealed envelope. After the sauce is injected, the sealing device seals the upper side of the semi-sealed envelope to form a sauce bag.

[0075] Among them, reference Figure 5 When the feeding device injects the sauce into the semi-sealed membrane, the driving assembly 23 can first drive the air outlet 22b of the material port blocking tube 22 away from the material outlet 21b, and push the material into the material conveying pipe 21 through the material injection port 21a. The material is sprayed into the semi-sealed membrane from the opened material outlet 21b. After a certain amount of sauce is injected, refer to Figure 4 The drive assembly 23 can be controlled to move the air outlet 22b of the material port sealing tube 22 toward the material outlet 21b, thereby sealing the material outlet 21b and preventing the material from being ejected. Furthermore, the air blowing assembly can be controlled to inject and withdraw air into and out of the air inlet 22a of the material port sealing tube 21. This air is ejected from the air outlet 22b and removes any remaining material from the material outlet 21b, preventing sauce from being trapped. Each package of sauce weighs approximately 30g.

[0076] In practice, hot filling can be used to push the material into the material delivery pipe. This ensures that the sauce is evenly mixed and the oil and sauce are not separated. The hot filling temperature range is 65°C to 85°C, for example, the hot filling temperature can be set to 70°C. This results in a uniformly mixed sauce bag.

[0077] The use of the middle feeding system of the utility model can reduce the sauce clamping rate from multiple aspects such as the material cutting method, air blowing, and material injection direction, thereby solving the problem of sauce clamping in horizontal sealing caused by the strong fluidity of hot filling sauce.

[0078] Although the present invention is disclosed as above, it is not limited thereto. Any person skilled in the art may make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be subject to the scope defined by the claims.
