Technical Field

[0001] The utility model relates to the technical field of food processing, in particular to a feeding system. Background Art

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

[0003] The sauce bag can be formed in the following manner: after the film is longitudinally sealed and one side is transversely sealed, the sauce is injected into the half-sealed film through a feed pipe, and then the other side of the film is transversely sealed.

[0004] In practice, sauce is often trapped in the sealed area of sauce packets. This not only affects the appearance of the sauce packet, but also causes leakage during the bag-cutting process, affecting the sealing performance of the packaging, and thus affecting the quality of the food and user experience.

[0033] In practice, after partially injecting sauce into the membrane, some sauce often remains in the nozzle and inside the discharge tube. This residual sauce will freely fall onto the sealed area of the membrane, causing sauce to be trapped within the sealed area of the sauce bag. Furthermore, when a highly fluid sauce is injected into a partially sealed membrane, it can cause significant splashing, which can also cause sauce to be trapped within the sealed area of the sauce bag.

[0034] Currently, to prevent sauce from getting stuck in the sealing area of the film, a suction device is typically used to suck the remaining sauce from the nozzle and inside the feeding tube back into the feeding tube after partially injecting the sauce into the film. However, this suction method is ineffective when the sauce has poor fluidity. Even when the sauce has good fluidity, sauce can still splash into the sealing area, resulting in a high rate of sauce sticking.

[0035] To address this problem, the present invention provides a feeding system, in which a blocking component is provided between the longitudinal sealing component and the transverse sealing component of the feeding system. The blocking component can prevent the material from splashing into the transverse sealing area of the membrane when the feeding pipe injects the material into the membrane, thereby achieving the purpose of reducing the sauce inclusion rate.

[0036] 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.

[0037] The present invention provides a material discharge system, which may include: a longitudinal sealing assembly, a transverse sealing assembly, a material discharge pipe, and a blocking assembly.

[0038] The longitudinal sealing component is used to perform longitudinal sealing operation on the envelope;

[0039] The transverse sealing assembly is located on one side of the longitudinal sealing assembly and is used to perform a first transverse sealing operation and a second transverse sealing operation on the longitudinally sealed envelope;

[0040] The feed pipe is used to inject material into the film after the transverse sealing assembly performs the first transverse sealing operation on the longitudinally sealed film and before performing the second transverse sealing operation;

[0041] The blocking assembly is located between the longitudinal sealing assembly and the transverse sealing assembly, and is used to prevent the material from splashing into the transverse sealing area of the membrane when the feed pipe injects the material into the membrane.

[0042] Unlike back-suction methods, this barrier component prevents material from splashing into the membrane's transverse seal when the material is injected into the membrane through the feed pipe. This spatially isolates the splashing material from the transverse seal, preventing material from being trapped. This method achieves a strong barrier effect for both fluid and non-fluid materials, thereby reducing the likelihood of sauce being trapped.

[0043] Figure 1 It is a side structural schematic diagram of the blanking system in one embodiment of the present utility model. Figure 2 for Figure 1 A cross-sectional structural diagram of the feeding system. Figures 1 to 2 In a specific implementation, the blanking system may include: a longitudinal sealing component 11, a blocking component 12, a blanking pipe 13 and a transverse sealing component.

[0044] Specifically, the barrier assembly 12 and the transverse seal assembly can be located below the longitudinal seal assembly 11. The barrier assembly 12 is located between the transverse seal assembly and the longitudinal seal assembly 11. The feed pipe 13 passes through the longitudinal seal assembly 11 and the barrier assembly 12. The feed pipe 13 can be hollow and tubular. The radial shape of the tubular structure can be circular (in which case the feed pipe 13 is cylindrical), square, or elliptical, etc., without limitation.

[0045] In a specific implementation, the film is usually rectangular or square. One film can be used to form multiple continuous material bags, including but not limited to sauce bags, and can also be bags containing other semi-solid or liquid materials, such as oil bags.

[0046] Before entering the longitudinal sealing assembly 11, the film may be folded in half. The folded film then has a longitudinal sealing area and two transverse sealing areas. For ease of description, the transverse sealing areas of the folded film may be referred to as a first transverse sealing area and a second transverse sealing area. The first transverse sealing area may be the transverse sealing area at the bottom of the folded film, and the second transverse sealing area may be the transverse sealing area at the top of the folded film.

[0047] The folded film is fed into the longitudinal sealing assembly. The longitudinal sealing assembly 11 may include a first longitudinal sealing roller 111 and a second longitudinal sealing roller 112. The first longitudinal sealing roller 111 has a first longitudinal sealing heating block protruding from its surface, while the second longitudinal sealing roller 112 has a second longitudinal sealing heating block protruding from its surface. The first and second longitudinal sealing heating blocks rotate synchronously. When the longitudinal sealing area of the folded film enters between the first and second longitudinal sealing heating blocks, the first and second longitudinal sealing heating blocks simultaneously heat the longitudinal sealing area of the folded film, thereby achieving the longitudinal sealing operation.

[0048] Because the first and second longitudinal sealing heating blocks protrude from the surfaces of the rollers on which they reside, there is sufficient spacing between the first and second longitudinal sealing rollers 111, 112 to allow the discharge tube 13 and the film to pass through. For example, if the discharge tube 13 is cylindrical, the spacing between the first and second longitudinal sealing rollers 111, 112 is greater than the diameter of the discharge tube 13. This allows material in the discharge tube 13 to pass smoothly through the longitudinal sealing assembly 11 and be sprayed into the film.

[0049] In a specific implementation, the blocking assembly 12 can prevent the material from splashing into the transverse sealing area of the membrane after the material is injected into the membrane by the discharge pipe 13 to meet the material injection volume requirement. The blocking assembly 12 can also prevent the material from splashing into the transverse sealing area of the membrane before the material is injected to meet the material injection volume requirement. In this case, the material remaining in the discharge pipe 13 can continue to descend, so that the material in the membrane meets the material injection volume requirement.

[0050] In a specific implementation, the blocking component 12 can be implemented in a variety of ways, which are not limited here, as long as it can spatially isolate the splashing material from the transverse sealing area of the envelope.

[0051] In one embodiment of the present invention, the blocking assembly 12 includes an extrusion structure for squeezing the discharge pipe 13 while passing through the longitudinally sealed film and the discharge pipe, thereby isolating the material injection area from the transverse sealing area of the film.

[0052] Specifically, the extrusion structure isolates the material injection area from the transverse sealing area of the film by squeezing the feed tube 13. The extrusion structure can squeeze the feed tube 13 after the feed tube 13 has injected material into the film to meet the material injection volume requirement, or it can squeeze the feed tube 13 before the material injection meets the material injection volume requirement.

[0053] The material injection area refers to the area on the membrane used for injecting material. When the extrusion structure squeezes the discharge tube 13, the space occupied by the discharge tube 13 is reduced, causing the discharge tube 13 to deform, thereby creating an interference fit between the discharge tube 13 and the extrusion structure. This reduces the gap between the discharge tube 13 and the extrusion structure. This prevents material ejected from the discharge tube 13 into the membrane from splashing into the second transverse sealing area through the gap between the discharge tube 13 and the extrusion structure, and also prevents material ejected from the discharge tube 13 into the membrane from splashing into the second transverse sealing area from within the discharge tube 13, thereby reducing the sauce inclusion rate.

[0054] It should be noted that the extrusion structure has no heating function and does not heat the envelope, so it will not affect the sealing of the envelope.

[0055] In a specific implementation, the extrusion structure can be realized in a variety of ways, which are not limited here, as long as the material injection area and the transverse sealing area of the membrane can be isolated by extruding the discharge pipe.

[0056] In one embodiment of the present invention, referring to Figure 1 and Figure 2 The extrusion structure may include a first sealing roller 121 and a second sealing roller 122. The first sealing roller 121 and the second sealing roller 122 are aligned to form a through hole; in the transverse direction, the minimum size of the through hole is smaller than the maximum size of the discharge pipe 13.

[0057] Specifically, a first groove 1211 is provided on the first sealing roller 121 at a position corresponding to the discharge pipe 13 , and a second groove is provided on the second sealing roller 122 at a position corresponding to the discharge pipe. The first groove 1211 and the second groove are aligned to form a through hole.

[0058] In a specific implementation, the first sealing roller 121 and the second sealing roller 122 can be made of materials such as polytetrafluoroethylene or silicone. The first groove 1211 surrounds the circumference of the first sealing roller 121 to form a closed annular groove. The second groove surrounds the circumference of the second sealing roller 122 to form a closed surrounding groove. The position of the first groove 1211 on the first sealing roller 121 and the position of the second groove on the second sealing roller 122 are always aligned and can correspond to the position of the discharge pipe 13. After the first groove 1211 and the second groove are aligned, a through hole is formed that penetrates the blocking component 12. The discharge pipe 13 passes through the through hole and discharges the material into the envelope below the blocking component 12.

[0059] In a specific implementation, the cross-sectional shape of the through hole along the transverse direction can be rectangular or elliptical, without limitation. In the transverse direction, the minimum dimension of the through hole is smaller than the maximum dimension of the discharge tube 13. In this case, the through hole can compress the discharge tube 13 in the radial direction, thereby preventing material from splashing from inside and outside the discharge tube 13 into the transverse sealing area.

[0060] Taking the feed tube 13 as an example, when the cross-section of the through hole along the transverse direction is rectangular, the width of the rectangle should be smaller than the diameter of the feed tube 13. When the cross-section of the through hole along the transverse direction is elliptical, the minor axis of the ellipse should be smaller than the diameter of the feed tube 13.

[0061] In a specific implementation, the depths of the first groove 1211 and the second groove can be adjusted based on the actual fluidity of the material, thereby changing the minimum transverse dimension of the through hole. For example, when the material fluidity is high, the minimum transverse dimension of the through hole can be reduced, while when the material fluidity is low, the minimum transverse dimension of the through hole can be increased.

[0062] In practice, the minimum size of the through hole in the transverse direction is adjusted based on the actual material cutting conditions. Specifically, the same first groove 1211 can have different depths at different locations, and the same second groove can have different depths at different locations. In this way, the through hole formed by aligning the first groove 1211 and the second groove will have different sizes at different locations in the transverse direction.

[0063] For example, when the material injected into the envelope does not meet the material injection amount requirement, the first sealing roller 121 and the second sealing roller 122 can be controlled to rotate so that the position where the through hole has a larger dimension in the transverse direction is used for the passage of the discharge pipe 13. When the material injected into the envelope basically meets the material injection amount requirement, the first sealing roller 121 and the second sealing roller 122 can be controlled to rotate so that the position where the through hole has a smaller dimension in the transverse direction is used for the passage of the discharge pipe 13.

[0064] Figure 3 This is a side structural schematic diagram of another blanking system in an embodiment of the present utility model. Figure 4 for Figure 3 Schematic diagram of the cross-section structure of the feeding system. Figure 1 and Figure 2 The difference between the embodiment shown in Figure 3 and Figure 4 In the illustrated embodiment, the first sealing roller 121 is provided with first sealing teeth 1212 , the second sealing roller 122 is provided with second sealing teeth 1222 , the first groove 1211 is located on the first sealing teeth 1212 , and the second groove is located on the second sealing teeth 1222 .

[0065] Specifically, the first sealing teeth 1212 can be protrusions extending axially along the first sealing roller 121. The top surface of the protrusions has the same shape as the circumferential shape of the first sealing roller 121. Multiple first sealing teeth 1212 can be arranged circumferentially along the first sealing roller 121. Each first sealing tooth 1212 is provided with a first groove 1211 that extends circumferentially through the first sealing tooth 1212. The depth of the first groove 1211 is the same at all locations.

[0066] The second sealing teeth 1222 can be protrusions extending axially along the second sealing roller 122. The top surface of the protrusions has the same shape as the circumferential shape of the second sealing roller 122. Multiple second sealing teeth 1222 can be arranged circumferentially along the second sealing roller 122. Each second sealing tooth 1222 is provided with a second groove that extends circumferentially through the second sealing tooth 1222. The depth of the second groove is the same at all locations.

[0067] In a specific implementation, the number of first sealing teeth 1212 is the same as the number of second sealing teeth 1222, and they rotate synchronously. By controlling the rotation of the first and second sealing rollers 121, 122, the feed tube 13 can be positioned within the through-hole formed by the alignment of the first and second grooves 1211, either when the material injection into the envelope substantially meets the required material injection volume, or before the material injection into the envelope substantially meets the required material injection volume. Because the through-hole's minimum radial dimension is smaller than the maximum radial dimension of the feed tube 13, the through-hole compresses the feed tube 13, preventing material from splashing from inside or outside the feed tube 13 into the transverse sealing area.

[0068] Since the first sealing teeth 1212 are protrusions extending in the axial direction of the first sealing roller 121, adjacent first sealing teeth 1212 will form grooves on the first sealing roller 121. Similarly, adjacent second sealing teeth 1222 will form grooves on the second sealing roller 122. When the first sealing teeth 1212 and the second sealing teeth 1222 rotate synchronously, the grooves between adjacent first sealing teeth 1212 and the grooves between adjacent second sealing teeth 1222 will be aligned. When it is necessary to inject material into the envelope, the discharge pipe 13 is controlled to be located in the space formed by the grooves between adjacent sealing teeth of adjacent first sealing teeth 1212. By controlling the height of the first sealing teeth 1212 and the second sealing teeth 1222, the minimum size of the space can be made larger than the maximum size of the discharge pipe 13, so that the discharge pipe 13 will not be squeezed, and the material can pass through the discharge pipe 13 smoothly.

[0069] In the specific implementation, refer to Figures 1 to 4 The transverse sealing assembly includes: a first transverse sealing assembly 141 and a second transverse sealing assembly 142 located on one side of the blocking assembly. The first transverse sealing assembly 141 is used to perform a first transverse sealing operation on the longitudinally sealed envelope, and the second transverse sealing assembly 142 is used to perform a second transverse sealing operation on the longitudinally sealed envelope.

[0070] Specifically, the first transverse sealing assembly 141 may be disposed below the blocking assembly 12 , and the second transverse sealing assembly may be disposed below the first transverse sealing assembly 141 .

[0071] The first transverse sealing assembly 141 includes a first transverse sealing roller 1411 and a second transverse sealing roller 1412. The first transverse sealing roller 1411 has a first transverse sealing heating block 1413 protruding from its surface, while the second transverse sealing roller 1412 has a second transverse sealing heating block 1414 protruding from its surface. The first and second transverse sealing heating blocks 1413, 1414 rotate synchronously. When the first transverse sealing area of the folded film enters between the first and second transverse sealing heating blocks 1413, 1414, they simultaneously heat the first transverse sealing area of the folded film, thereby achieving the first transverse sealing operation.

[0072] In a specific implementation, the distance between the blocking assembly and the transverse sealing assembly should be adjusted so that when the first transverse sealing area of the folded film enters between the first transverse sealing heating block 1413 and the second transverse sealing heating block 1414, the second transverse sealing area of the folded film is still located within the blocking assembly. In this way, after the first transverse sealing operation, when the discharge pipe 13 injects material into the film, the blocking assembly can block the second transverse sealing area of the folded film.

[0073] In a specific implementation, the second transverse sealing assembly 142 may include a third transverse sealing roller 1421 and a fourth transverse sealing roller 1422. The third transverse sealing roller 1421 has a third transverse sealing heating block 1423 protruding from its surface, while the fourth transverse sealing roller 1422 has a fourth transverse sealing heating block 1424 protruding from its surface. The third and fourth transverse sealing heating blocks 1423, 1424 rotate synchronously. When the second transverse sealing area of the folded film enters between the third and fourth transverse sealing heating blocks 1423, 1424, they simultaneously heat the second transverse sealing area of the folded film, thereby achieving the second transverse sealing operation.

[0074] In one embodiment of the present invention, the first transverse sealing assembly and the second transverse sealing assembly can move synchronously with the blocking assembly.

[0075] Specifically, refer to Figure 3 and Figure 4When the first sealing roller 121 is provided with first sealing teeth 1212 and the second sealing roller 122 is provided with second sealing teeth 1222, the number of first sealing teeth 1212 and second sealing teeth 1222 can be set to match the number of first transverse sealing heating blocks 1413 and second transverse sealing heating blocks 1414. The first transverse sealing assembly 141 can be controlled as the driving wheel and the blocking assembly 12 as the driven wheel, and a gear transmission structure can be provided to connect the blocking assembly 12 to the first transverse sealing assembly 141. Thus, after longitudinal sealing, the packaging bag passes through the blocking assembly 12 and enters the first transverse sealing assembly 141. While the first transverse sealing assembly 141 is heat-sealing the bag, the first sealing teeth 1222 engage with each other.

[0076] In the prior art, a silicone nozzle is provided at one end of the discharge pipe. The silicone nozzle needs to be fixed to the discharge pipe through external gas measures such as tape each time it is used, which is inconvenient to use.

[0077] In one embodiment of the present invention, referring to Figures 1 to 4 For ease of use, a detachable discharge nozzle 15 can be provided below the discharge pipe 13. In this way, the discharge nozzle 15 can be fixed to the discharge pipe 13 without the need for external measures, thereby spraying the material into the envelope through the discharge nozzle 15, further preventing the material from splashing back.

[0078] In one embodiment, the discharge nozzle 15 and the discharge pipe 13 can be detachably connected by snapping.

[0079] for example, Figure 5 for Figure 2 and Figure 4 Schematic diagram of the enlarged structure of part A. Figure 5 A plurality of grooves 131 may be provided on the end of the discharge pipe 13 for connecting to the discharge nozzle 15, and a corresponding groove 15a may be provided on the end of the discharge nozzle 15 for connecting to the discharge pipe 13. In this case, the plurality of grooves 131 are dispersed on the end of the discharge nozzle 15. The plurality of grooves 15a are also dispersed on the end of the discharge pipe 13.

[0080] When the nozzle 15 is needed, the groove 15a on the nozzle 15 can be inserted into the groove 131 of the tube 13 under the action of external thrust, thereby securing the nozzle 15 to the tube 13. When the nozzle 15 is no longer needed, the groove 15a on the nozzle 15 can be disengaged from the groove 131 of the tube 13 by squeezing the tube 13 with external pressure, thereby removing the nozzle 15 from the tube 13. The groove 131 and the groove 15a have the same structure; for example, both can be hemispherical grooves.

[0081] In one embodiment, the discharge nozzle 15 and the discharge pipe 13 can be rotatably connected by a snap-fit method. Figure 5 , only one groove 131 may be provided on the end of the discharge nozzle 15, and the groove 131 may surround the end of the discharge nozzle 15. Alternatively, only one groove 15a may be provided on the end of the discharge tube 13, and the groove 15a also surrounds the end of the discharge nozzle 15. Thus, after the groove 15a is inserted into the groove 131 of the discharge tube 13, the position of the groove 15a relative to the groove 131 can be changed by rotating the groove 15a, thereby changing the injection position.

[0082] In one embodiment of the present invention, referring to Figure 2 The discharge nozzle 15 includes: a connecting portion 151 and an inclined portion 152, the connecting portion 151 is used to connect the discharge pipe 13, and the inclined portion 152 is used to discharge the material in an inclined manner.

[0083] Specifically, the discharge nozzle 15 can be made of stainless steel. A groove 131 can be provided on the connecting portion 151. One end of the inclined portion 152 is connected to the connecting portion 151, and the other end serves as a discharge port. The connecting portion 151 and the inclined portion 152 can be integrally formed. The inclined portion 152 can be inclined from the connecting portion 151 to one side of the connecting portion 151, thereby forming a certain angle with the connecting portion 151, and the angle is an obtuse angle. The discharge port is formed at one end of the inclined portion 152, and can be facing downward or to the side (i.e., the axial direction of the first sealing roller 121).

[0084] Since the inclined portion 152 is inclined relative to the connecting portion 151 , the impact force of the falling material can be mitigated, thereby further preventing back splashing.

[0085] In one embodiment of the present invention, referring to Figures 1 to 4 The blanking system may further include: a film forming component, the film forming component having a forming rod 16, the forming rod 16 being located in the film and used to assist in film forming; the forming rod 16 passes through the longitudinal sealing component 11 and the blocking component 12.

[0086] Specifically, when a single film is used to form a material bag, it is folded in half before entering the longitudinal sealing assembly 11. The longitudinal seal is then applied to the open side of the folded film. Forming rods 16 are used to tighten the film at the fold, ensuring that the longitudinally sealed areas of the film are aligned on the open side.

[0087] The forming rod 16 can pass through the gap between the first longitudinal sealing roller 111 and the second longitudinal sealing roller 112 in the longitudinal sealing assembly 11. The first sealing roller 121 and the second sealing roller 122 of the barrier assembly 12 should also be provided with corresponding grooves to allow the forming rod 16 to pass through. The grooves for the forming rod 16 to pass through can be similar to those described for the first and second grooves. The difference is that the minimum dimension of the through-hole formed by the first and second grooves should be larger than the maximum dimension of the forming rod 16 to avoid squeezing the forming rod 16.

[0088] With the unloading system in this embodiment of the utility model, the film is folded in half and then enters the longitudinal sealing assembly 11 for the longitudinal sealing operation. After the longitudinal sealing is completed, the film first enters the barrier assembly. When the lower portion of the film enters the first transverse sealing assembly and performs the first transverse sealing operation, the unloading pipe 13 sprays the material into the film. At this time, the second transverse sealing area of the film is shielded by the barrier assembly, preventing material from splashing. The film then continues its downward movement and enters the second transverse sealing assembly for the second transverse sealing operation.

[0089] In practical applications, a piece of film can be used to form multiple continuous material packages. During the formation stage of each material package, the blocking component can block the material splashing, thereby reducing the sauce inclusion rate.

[0090] 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.
