Description

Technical Field

[0001] This utility model relates to a stuffed food processing device, and more specifically, this utility model mainly relates to a wide-body filling pipe. Background Technology

[0002] Machinery used for producing dumplings and other stuffed foods typically has stations for receiving dough, filling, and shaping. At the filling station, filling pipes are used to inject the filling into the dough on the forming mold. However, as people's requirements for the shape of dumplings and other stuffed foods have increased, traditional cylindrical filling pipes have gradually become inadequate. For example, when filling is injected into the dough, it tends to accumulate in the middle, and when the dough is wide, it is also easy to be squeezed out during the wrapping process. At the same time, the filling is too concentrated, which affects the shape of the dumplings and other foods after they are wrapped. To address the aforementioned issues, existing technologies have proposed improvements, specifically employing two parallel filling pipes for simultaneous filling. By controlling the amount of filling in each pipe, the distribution area of ​​the filling on the dough can be increased. However, this approach also introduces new problems. For instance, dual-pipe filling still involves each pipe injecting filling into the dough separately, resulting in gaps between the filling and dough. These gaps can cause the dough to dent after being wrapped, affecting the shape of dumplings and other filled foods. Therefore, it is necessary to redesign and improve these filling pipes for dumplings and other filled foods. Utility Model Content

[0003] One of the objectives of this invention is to address the aforementioned shortcomings by providing a wide-body filling pipe, which aims to solve the technical problem in the prior art where filling tends to accumulate in the middle of the dough after being injected, affecting the shape of dumplings and other foods after they are wrapped.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] This utility model provides a wide-body filling pipe, including a filling tube body, an internal filling piston, a filling inlet on the side of the filling tube body, and a filling outlet at the bottom of the filling tube body corresponding to a molding mold. The molding mold has an enclosing area, and the ratio between the lateral width of the filling outlet and the lateral width of the enclosing area is 0.5-1:1. The cross-sectional profile of the filling piston matches the shape of the filling outlet.

[0006] As a preferred embodiment, a further technical solution is that the outer wall of the filling piston is in close contact with the inner wall of the filling tube.

[0007] A further technical solution is that the interior of the filling-pushing piston is provided with an airflow channel, and the lower end of the filling-pushing piston is provided with multiple small air holes, all of which are connected to the airflow channel, and the airflow channel is used to connect with an external air source.

[0008] A further technical solution is that the longitudinal width of the filling outlet is less than the longitudinal width of the enclosing area, and the longitudinal width is the longitudinal width of the filling outlet and the enclosing area on the horizontal plane.

[0009] Compared with the prior art, one of the beneficial effects of this utility model is that by setting the width of the filling outlet of the filling tube to correspond to the wrapping area of ​​the forming mold, the filling can be evenly distributed on the dough of the forming mold during filling. This not only prevents the filling from being squeezed out during wrapping, but also improves the appearance of the dumplings after wrapping. At the same time, the wide-body filling tube provided by this utility model has a simple structure and is suitable for installation on various dumpling machines and other filling food machinery, with a wide range of applications.

[0015] The present invention will be further described below with reference to the accompanying drawings.

[0016] refer to Figure 1 and Figure 2As shown, one embodiment of this utility model is a wide-body filling pipe. This filling pipe can be used in the filling station of filling machinery for dumplings and other filled foods. Its structure includes a hollow filling tube body 1, inside which is a filling piston 2. The filling tube body 1 is fitted onto the outside of the filling piston 2. A filling inlet 11 is provided on the side of the filling tube body 1, which needs to be connected to the filling conveying pipe during use. A filling outlet 12 is also provided at the lower part of the filling tube body 1. The filling outlet 12 needs to correspond to the position of the forming mold 3 during use. The forming mold 3 has an enclosing area 31. It is worth noting that the ratio between the lateral width of the filling outlet 12 and the lateral width of the enclosing area 31 is 0.8:1; the inventors, through experiments, found that a ratio of 0.5-1:1 is more suitable. Within a 1:1 ratio, it ensures that the filling is evenly distributed on the dough of the forming mold 3 during injection, avoiding the accumulation of filling in the middle that easily occurs in similar structures in the prior art, affecting the wrapping shape or causing the filling to be squeezed out. Corresponding to the widened filling outlet 12, the cross-sectional profile of the aforementioned filling pusher 2 must match the shape of the filling outlet 12. At the same time, during use, the outer wall of the aforementioned filling pusher 2 must also be in close contact with the inner wall of the filling tube 1 to ensure that all the filling conveyed by the conveying pipe is pushed out each time. Preferably, the longitudinal width of the aforementioned filling outlet 12 is smaller than the longitudinal width of the wrapping area 31. This longitudinal width is the longitudinal width of the filling outlet 12 and the wrapping area 31 on the horizontal plane, so as to better match the forming mold and produce dumplings with better shape.

[0017] In this embodiment, by setting the width of the filling outlet of the filling tube 1 to correspond to the wrapping area 31 of the forming mold 3, that is, by widening the filling outlet 12, the filling can be evenly distributed on the dough of the forming mold 3 during filling. This not only prevents the filling from being squeezed out during wrapping, but also improves the appearance of dumplings and other filled foods after wrapping.

[0018] Combination Figure 2 As shown, in a more preferred embodiment of this invention to solve the technical problem, to prevent the filling from sticking to the filling piston 2 after each filling, especially for semi-fluid fillings, the aforementioned sticking phenomenon is more obvious and will affect the filling process and the final product's encapsulation shape, an airflow channel can be added inside the filling piston 2. Correspondingly, multiple small air holes 21 are provided at the lower end of the filling piston 2. These small air holes 21 are evenly distributed on the lower end surface of the filling piston 2, and all of the aforementioned small air holes 21 are connected to the airflow channel, which is connected to an external air source during use. The high-pressure airflow from the external air source is blown out through the airflow channel from the multiple small air holes 21, thereby causing the filling to detach from the filling piston 2 via the airflow.

[0019] refer to Figure 3 and Figure 4As shown, in actual use, the initial state of the pushing piston 2 in one of the preferred embodiments of this utility model is as follows: Figure 4 As shown, when the forming mold 3 containing the dough enters the filling station, the filling in the hopper is transported to the filling tube 1 through the conveying pipe. When the filling enters the filling tube 1 through the filling inlet 11, the filling piston 2 moves downward, pushing the filling into the filling tube 1 downward from the filling outlet 12. At this time, the filling piston 2 is located at the bottom, flush with or slightly beyond the edge of the filling outlet 12, so that the filling enters the dough in the wrapping area 31 of the forming mold 3. Since the filling outlet 12 has been widened to correspond to the wrapping area 31, the filling pushed out by the filling piston 2 is evenly distributed on the dough in the wrapping area 31. Therefore, when wrapping is performed in the subsequent wrapping station, the same amount of filling is not easily squeezed out, which also improves the appearance of the finished product. Simultaneously, after the filling-pushing piston 2 descends to its lowest point, a high-pressure airflow from an external air source blows the filling out through the small air hole 21, causing the filling to detach from the piston 2 and thus preventing sticking. After the filling is pushed out, the current forming mold enters the wrapping station, and the filling-pushing piston 2 returns to its original position. Figure 4 The state shown indicates that the next piece of leather on the molding die 3 will be used for the injection molding operation.
