Description

Technical Field

[0001] The invention relates to the technical field of automatic processing of pancakes, and in particular to a liquid feeding system. Background Art

[0002] Jianbing Guozi is a local specialty food. The traditional production process of Jianbing Guozi is to spread the pancakes manually and then add various seasonings and auxiliary materials to the pancakes. This purely manual production method can easily result in unstable taste and quality of Jianbing Guozi, and low production efficiency.

[0003] Therefore, some Jianbing Guozi machines that can automatically make Jianbing Guozi have appeared on the market. However, in the automatic production process, sesame seeds and various sauces need to be added to the Jianbing Guozi machine for seasoning. Most of the existing sesame scattering devices store the sesame seeds in a storage container in advance, and then use a screw to push the sesame seeds to the scattering container, and then the sesame seeds are scattered on the surface of the pancake skin by the scattering container. However, it is found in actual use that it is impossible to scatter all the sesame seeds in the scattering container within the set scattering time, and when stopping the scattering and moving the scattering container to the initial position, there is a problem that the remaining sesame seeds fall out from the pouring port, making the Jianbing Guozi machine difficult to clean.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0043] See also Figure 1 The figure is a schematic diagram of the structure of a liquid feeding system assembly provided by a preferred embodiment of the present application. Figure 1 In the embodiment shown, the liquid feeding system includes a feeding support frame 1, on which a liquid feeding component 2 is provided, on which a sesame sprinkling component 3 is provided, and on which a driving member 4 for pushing the liquid feeding component 2 to move on the feeding support frame 1 is provided, so that when making pancakes, the component can be pushed to the upper end of the pancakes to add liquid auxiliary materials and sesame seeds to the pancakes. Of course, other embodiments can also be used to add crushed peanuts, crushed chocolate, etc.

[0044] Specifically, if Figure 7 As shown, the liquid feeding assembly 2 includes a housing 20, a liquid discharge valve 21 is provided on the housing 20, and a material pipe joint 22 connected to a liquid delivery pipe is provided on the liquid discharge valve 21. The liquid auxiliary material is driven by a pump and transported to the liquid discharge valve 21 through the liquid delivery pipe, and discharged by the liquid discharge valve 21.

[0045] Specifically, if Figure 5 , Figure 6 As shown, the sesame scattering assembly 3 includes a sesame silo 30, which is connected to the housing 20 via a rotating shaft 31. The housing 20 is also provided with a first cylinder 32 for driving the sesame silo 30 to rotate around the rotating shaft 31. The sesame silo 30 has a discharge hole 300, and the sesame silo 30 is provided with a baffle 34 via a hinge 33. A second cylinder 35 is installed on the outer wall of the sesame silo 30, and the output end of the second cylinder 35 is connected to the baffle 34, which is used to drive the baffle 34 to rotate around the hinge 33 to open or close the discharge hole 300. The output end of the first cylinder 32 is located on one side of the sesame silo 30. Under the push of the first cylinder 32, the sesame silo 30 swings in the vertical direction, so that the sesame in the silo can flow and fall out of the discharge hole 300 smoothly. Figure 6 It is a structural schematic diagram of the second cylinder 35 unfolding the baffle 34.

[0046] Please continue to refer to Figure 5, two groups of first bars 301 are arranged on the side wall of the sesame silo 30, an axle seat is arranged on the housing 20, two groups of second bars 302 are arranged on the axle seat, a torsion spring 36 is arranged on the outer sleeve of the rotating shaft 31, a first force arm 361 of the torsion spring 36 is limited between the two groups of first bars 301, and a second force arm 362 of the torsion spring 36 is limited between the two groups of second bars 302. It can be understood that the two force arms of the torsion spring 36 are fixed between the first bar 301 and the second bar 302, and when the first bar 301 rotates around the center of the torsion spring 36, the torsion spring 36 can pull them back to the initial position, and then when the first cylinder 32 pushes the sesame silo 30 to rotate, the torsion spring 36 can make the sesame silo 30 vibrate, and avoid the problem of bridging the discharge hole 300.

[0047] The composition and connection relationship of the liquid discharge valve 21 will be described in detail below.

[0048] According to an example of the present disclosure, by Fig.10 From the internal structure shown, it can be seen that the liquid discharge valve 21 includes a valve seat 210 and a cylinder plunger assembly 220. The valve seat 210 has a cavity 2100 and a feed port 2102 and a discharge port 2101 connected to the cavity 2100. A material pipe joint 22 is provided on the feed port 2102. The liquid delivery pipe is connected to the material pipe joint 22 to deliver the liquid auxiliary material to the feed port 2102, enter the cavity 2100, and then flow out from the discharge port 2101.

[0049] To prevent residual liquid from remaining in the cavity 2100 and the residual liquid from dripping, Figure 7-Figure 10 As shown, a cylinder plunger assembly 220 is installed on the valve seat 210, and the cylinder plunger assembly 220 pushes out the residual liquid in the cavity 2100 by means of push injection. Specifically, the cylinder plunger assembly 220 includes a plunger 221 extending into the cavity 2100 and a cylinder 222 driving the plunger 221 to open and close the discharge port 2101, the push rod 223 of the cylinder 222 is connected to the plunger 221, and the plunger 221 is slidably connected to the inner wall of the cavity 2100. The cylinder 222 controls the plunger 221 to open and close the discharge port 2101. When liquid auxiliary material is loaded, the discharge port 2101 is opened, and the liquid auxiliary material is input into the feed port 2102. Then, gas is filled into the exhaust throttling joint 2103 to push the plunger 221 toward the discharge port 2101. On the one hand, the residual liquid in the cavity 2100 is discharged from the discharge port 2101 by means of air pressure. On the other hand, after the loading is completed, the plunger 221 closes the discharge port 2101 to prevent the residual liquid in the cavity 2100 from dripping. When loading, gas is first filled into the straight joint 2104 to push the plunger 221 away from the discharge port 2101.

[0050] In some embodiments, the feed port 2102 is disposed on the side wall of the valve seat 210, and the discharge port 2101 is disposed at the bottom of the valve seat 210. When the plunger 221 closes the discharge port 2101, the connection between the feed port 2102 and the cavity 2100 is closed. By adopting the "side-in and bottom-out" method, after the loading is completed, the discharge port 2101 and the feed port 2102 can be closed simultaneously by the plunger 221.

[0051] like Figure 8 and Fig.10 As shown, the contact end between the plunger 221 and the discharge port 2101 is configured as a frustum surface 224, and the discharge port 2101 has a conical surface adapted to the frustum surface 224. This configuration facilitates the liquid auxiliary material to fall out along the conical surface.

[0052] like Figure 7 , Fig.10 As shown, the valve seat 210 includes a valve cover 211 , an upper valve body 212 and a lower valve body 213 which are arranged in sequence, wherein a first sealing ring 214 is arranged between the valve cover 211 and the upper valve body 212 , and a second sealing ring 215 is arranged between the upper valve body 212 and the lower valve body 213 .

[0053] Furthermore, the plunger 221 is provided with an upper O-ring 216 that contacts the upper valve body 212 when the plunger 221 closes the discharge port 2101 , and a lower O-ring 217 that contacts the upper valve body 212 when the discharge port 2101 is opened.

[0054] Furthermore, the valve cover 211 and the upper valve body 212 , as well as the lower valve body 213 and the upper valve body 212 are connected via screws 218 .

[0055] In addition, if Figure 7 As shown, the valve seat 210 is roughly square in structure, having an array of separated cavities 2100, a feed port 2102 and a discharge port 2101, and each corresponding position of the valve seat 210 is provided with a cylinder plunger assembly 220 of the above structure, wherein the liquid auxiliary materials transported to the cavity 2100 of the valve seat 210 can be matched according to different tastes. Taking pancakes as an example, different sauces can be set respectively, and consumers can add corresponding liquid auxiliary materials according to their own tastes.

[0056] like Figure 4 As shown, the driving member 4 is an electric push rod, an output end of which is fixedly connected to the housing 20 via an electric push rod front support 40, and the other end of the electric push rod is fixedly connected to the loading support frame 1 via an electric push rod rear support 41.

[0057] In some embodiments, a drag chain assembly 5 is also included, one end of the drag chain assembly 5 is connected to the loading support frame 1, and the other end is connected to the shell 20 through the drag chain mounting part 50. Cables, air pipes and other lines can be routed through the drag chain assembly 5 to avoid damage to the cables or hoses.

[0058] like Figure 2 As shown, a linear guide rail 11 is disposed at the bottom of the housing 20 , a slider 10 is disposed on the loading support frame 1 , and the linear guide rail 11 is slidably mounted on the slider 10 .

[0059] like Figure 3 As shown, the shell 20 has a sensing part 60, and a proximity switch 6 for sensing the sensing part 60 is provided on the feeding support frame 1 along the moving path of the sensing part 60. After the shell 20 reaches this position, the proximity switch 6 sends a signal that the target point for placing the auxiliary material has been reached or that the signal has returned to the initial position.
