[0039] Example

[0040] At present, ice cream infusion products can only be infused with two liquid materials at the same time, one is puffed material and the other is sauce. The discharge channel of the sauce in the infusion latte art mechanism is mainly set on the outside of the ice cream discharge channel or at the concave angle. During the discharge process, due to the swelling effect of the ice cream puffed material, the sauce and other ice cream additional liquid materials can only adhere to the surface of the product and cannot be embedded in the ice cream liquid. Therefore, the infused jam pattern can only be infused into the outer layer of the product, and it is mostly one color. In addition, the sauce is often mixed in advance, making it impossible for the product to achieve the infusion molding of the sheet structure, which makes the consumer experience bad. With the rapid development of the ice cream industry, consumers have higher and higher requirements for products. It is urgent to produce a product with multiple compound flavors and a jam pattern in the center of the product.

[0041] To this end, this embodiment provides a pouring device, which can embed the sauce into the ice cream liquid to achieve pouring molding of the sheet structure.

[0042] In one embodiment, if Figures 1 to 5As shown, the filling device includes a main material pipe 1, a rotating pipe 2, an auxiliary material feeding mechanism, and a filling head. The main material pipe 1 is suitable for feeding the main material liquid; the rotating pipe 2 is arranged outside the main material pipe 1, and can rotate relative to the main material pipe 1 under the drive of the first driving mechanism; a discharge pipe 3 is arranged on the inner side of the rotating pipe 2, and the discharge pipe 3 is located below the main material pipe 1. A discharge slit 301 is arranged on the tube wall of the discharge pipe 3, and the discharge pipe 3 and the discharge slit 301 thereon both extend along the radial direction of the rotating pipe 2, and the rotating direction of the rotating pipe 2 is that the side without the discharge slit 301 is located in front of the side with the discharge slit 301; the auxiliary material feeding mechanism is connected with the discharge pipe 3, and is used for conveying the auxiliary material liquid to the discharge pipe 3; the filling head is arranged below the rotating pipe 2, and a discharge nozzle 4 is arranged on the filling head. The main material liquid can be ice cream liquid, and the auxiliary material liquid can be jam.

[0043] In this embodiment, during pouring, the main material liquid enters through the main material pipe 1, and the auxiliary material liquid is transported to the discharge pipe 3 through the auxiliary material feeding mechanism. When the rotating tube 2 is driven by the first driving mechanism to rotate relative to the main material pipe 1, the discharge pipe 3 is driven to rotate. The discharge pipe 3 and the discharge slit 301 on the discharge pipe 3 both extend along the radial direction of the rotating tube 2. When the main material liquid passes through the discharge pipe 3, the discharge pipe 3 extends into the interior of the main material liquid. During the rotation of the discharge pipe 3, the auxiliary material liquid continuously flows out from the discharge slit 301, so that the auxiliary material liquid is embedded in the main material liquid. The discharge pipe 3 rotates one circle, and a layer of auxiliary material liquid in the form of a sheet can be formed in the main material liquid, and finally flows into the mold or container through the discharge nozzle 4 of the pouring head. When the main material liquid is ice cream liquid and the auxiliary material liquid is jam, jam with a sheet structure can be poured into the ice cream liquid, so that a jam pattern is formed in the center of the product.

The pouring device further comprises a fixed seat 5, and a feed channel 501 connected to the liquid circulation groove 201 is provided on the fixed seat 5, and an auxiliary material feeding mechanism is connected to the feed channel 501. In this embodiment, by providing the liquid circulation groove 201 on the outside of the rotating tube 2, and providing the feed channel 501 connected to the liquid circulation groove 201 on the fixed seat 5, when auxiliary material liquid needs to be added, the auxiliary material feeding mechanism transports the auxiliary material liquid to the feed channel 501, and the auxiliary material liquid flows into the liquid circulation groove 201 through the feed channel 501, and finally flows out through the discharge tube 3. This embodiment only needs to connect the auxiliary material feeding mechanism with the feed channel to realize feeding of the rotating discharge tube 3, and the structure is simple and reliable. In other alternative embodiments, the auxiliary material feeding mechanism can be made to rotate along with the discharge pipe 3 to feed the material to the discharge pipe 3 during the rotation of the discharge pipe 3 .

[0045] It should be noted that the fixing seat 5 is sealedly connected to the rotating tube 2, so that the feed channel 501 is sealedly connected to the liquid circulation groove 201, avoiding the auxiliary liquid from flowing to other places and causing waste of the auxiliary liquid.

[0046] On the basis of the above embodiments, in a preferred embodiment, the auxiliary material feeding mechanism comprises a valve seat 6, a reversing ball valve 7 and a reversing rod 8. The valve seat 6 is fixedly connected to the fixed seat 5; the reversing ball valve 7 is rotatably arranged in the valve seat 6, the reversing ball valve 7 is provided with a liquid material channel, the reversing ball valve 7 has a first position that connects the liquid material channel with the feed channel 501 and a second position that disconnects the liquid material channel from the feed channel 501; the reversing rod 8 is connected to the reversing ball valve 7, and the reversing rod 8 is suitable for driving the reversing ball valve 7 to rotate under the drive of the second driving mechanism. In this embodiment, when it is necessary to add auxiliary liquid to the main material liquid, the reversing valve is switched to the first position, and the auxiliary liquid can enter the feed channel 501 on the fixed seat 5 through the material liquid channel in the reversing ball valve 7, and enter the material liquid circulation groove 201 through the feed channel 501, and finally flow out through the discharge pipe 3 and be added to the main material liquid; when it is not necessary to add auxiliary liquid, the reversing valve is switched to the second position, at this time the material liquid channel is disconnected from the feed channel 501, that is, it is not connected, and the auxiliary liquid cannot continue to enter the feed channel 501. This embodiment can facilitate the control of whether to add auxiliary liquid by setting the reversing ball valve 7.

[0047] On the basis of the above embodiments, in a preferred embodiment, the liquid channel includes an X-axis channel 9, a Y-axis channel 10, and a Z-axis channel 11 distributed in a three-dimensional coordinate system, the Z-axis channel 11 is suitable for being connected to an auxiliary liquid source, the reversing ball valve 7 can rotate around the axis of the Z-axis channel 11, the perfusion device also includes a reversing valve clamping lock 12, the reversing valve clamping lock 12 is fixedly connected to the valve seat 6 and is arranged on the side of the reversing ball valve 7 away from the fixed seat 5, the reversing valve clamping lock 12 has a reflux channel 1201, the reflux channel 1201 and the feed channel 501 are distributed on both sides of the reversing ball valve 7, when the reversing ball valve 7 is in the first position, the Z-axis channel 11 is connected to the X-axis channel 9 and the feed channel 501, when the reversing ball valve 7 is in the second position, the Z-axis channel 11 is connected to the Y-axis channel 10 and the reflux channel 1201. In this embodiment, when it is necessary to add auxiliary liquid to the main liquid, the reversing valve is switched to the first position, and the auxiliary liquid can enter the feed channel 501 on the fixed seat 5 through the Z-axis channel 11 and the X-axis channel 9 in the reversing ball valve 7 in sequence, and enter the liquid circulation groove 201 through the feed channel 501, and finally flow out through the discharge pipe 3 and added to the main liquid. At this time, as shown in the figure, the lower end of the Y-axis channel 10 is against the valve seat 6 and does not flow; when it is not necessary to add auxiliary liquid, the reversing valve is switched to the first position. The directional valve is switched to the second position, at which time the reversing ball valve 7 rotates 90° around the axis of the Z-axis channel 11, the lower end of the X-axis channel 9 abuts against the valve seat 6 and does not flow, and the Y-axis channel 10 is connected to the reflux channel 1201. The auxiliary material liquid can enter the reflux channel 1201 in the reversing valve compression lock 12 through the Z-axis channel 11 and the Y-axis channel 10 in the reversing ball valve 7 in turn, so that the auxiliary material liquid refluxes, which can reduce the pressure in the valve seat 6 when the reversing ball valve 7 is closed, avoiding affecting the molding state.

[0048] On the basis of the above embodiments, in a preferred embodiment, the reversing valve pressing lock 12 is connected to the valve seat 6 by threads. In this embodiment, the connection between the reversing valve pressing lock 12 and the valve seat 6 is simple and convenient, and the position of the reversing ball valve 7 can be determined not to move.

In this embodiment, the provision of the first sealing gasket bowl 13 and the second sealing gasket bowl 14 can achieve sealing of the reversing ball valve 7. When it is necessary to add auxiliary liquid to the main liquid, the reversing valve is switched to the first position, and the auxiliary liquid can flow through the Z-axis channel 11 and the X-axis channel 9 in the reversing ball valve 7 through the first through hole 1301 in sequence, and then enter the feed channel 501 on the fixed seat 5, and enter the liquid circulation groove 201 through the feed channel 501, and finally flow out through the discharge pipe 3 and add to the main liquid. At this time, as shown in the figure, the lower end of the Y-axis channel 10 is against the valve seat 6 and does not flow; when it is not necessary to add auxiliary liquid, the auxiliary liquid can flow through the first through hole 1301 through the Z-axis channel 11 and the X-axis channel 9 in the reversing ball valve 7, and then enter the feed channel 501 on the fixed seat 5, and enter the liquid circulation groove 201 through the feed channel 501, and finally flow out through the discharge pipe 3 and add to the main liquid. When adding auxiliary liquid, the reversing valve is switched to the second position. At this time, the reversing ball valve 7 rotates 90° around the axis of the Z-axis channel 11, the lower end of the X-axis channel 9 abuts against the valve seat 6, and no flow occurs. The Y-axis channel 10 is connected to the second through hole 1401 and the reflux channel 1201. The auxiliary liquid can flow through the Z-axis channel 11 and the Y-axis channel 10 in the reversing ball valve 7, through the second through hole 1401, and enter the reflux channel 1201 in the reversing valve compression lock 12, so that the auxiliary liquid refluxes.

[0050] like Figure 4 As shown, the first sealing bowl 13 and the second sealing bowl 14 are bowl-shaped structures, the inner side of which has a spherical surface adapted to the reversing ball valve 7, and are made of soft material, and have a good fit with the reversing ball valve 7, thereby playing a sealing role.

[0051] On the basis of the above embodiment, in a preferred embodiment, at least two groups of discharge pipes 3 are provided along the axial direction of the rotating tube 2, and each group of discharge pipes 3 is located at the same height, and correspondingly, at least two auxiliary material feeding mechanisms are provided, and at least two auxiliary material feeding mechanisms are arranged at intervals in the axial direction of the rotating tube 2. In this embodiment, by providing at least two auxiliary material feeding mechanisms, at least two auxiliary material liquids can be simultaneously infused or multiple layers of auxiliary material liquids can be added to the main material liquid, and at least two auxiliary material feeding mechanisms are arranged at intervals in the axial direction of the rotating tube 2, which can avoid the phenomenon of cross-material and material mixing of the two auxiliary material liquids.

[0052] like Figure 4 As shown, there are two groups of discharge pipes 3, and correspondingly, two auxiliary material feeding mechanisms are also provided, and the two auxiliary material feeding mechanisms are respectively arranged on both sides of the fixing seat 5 and are spaced apart in the height direction.

In this embodiment, since each group of discharge pipes 3 includes two discharge pipes 3 arranged opposite to each other, the rotating tube 2 can be rotated 180° to add a layer of auxiliary liquid. Of course, in an alternative embodiment, each group of discharge pipes 3 includes only one discharge pipe 3, and the rotating tube 2 is rotated 360° to add a layer of auxiliary liquid. In another alternative embodiment, each group of discharge pipes 3 may include more than two discharge pipes 3.

[0054] On the basis of the above embodiment, in a preferred embodiment, the pouring device further comprises a second driving mechanism, which can simultaneously drive at least two reversing rods 8 to rotate. In this embodiment, only one second driving mechanism is provided to drive multiple reversing rods 8 to rotate, thereby driving multiple reversing ball valves 7 to switch states, which facilitates the control of multiple reversing ball valves 7, and has a simple and compact structure.

In this embodiment, when the linear driving source drives the slide 15 to slide up and down, it drives the slider in each slide groove 1501 to move up and down. Since one end of the connecting rod 16 is fixedly connected to the reversing rod 8, the slider slides along the slide groove 1501 and drives the connecting rod 16 to rotate relative to the axis of the reversing rod 8 during the process of moving up and down, thereby driving the reversing rod 8 to rotate around its axis, and then switching the reversing ball valve 7 between the first position and the second position. The second driving mechanism of this embodiment has a simple structure and is easy to operate and control.

[0056] In one embodiment, Figure 1As shown, there are two auxiliary material feeding structures, which are respectively arranged on both sides of the fixed seat 5, specifically, one auxiliary material feeding mechanism is arranged on the first side surface of the fixed seat 5, and the other auxiliary material feeding mechanism is arranged on the second side surface of the fixed seat 5, the first side surface is opposite to the second side surface, the third side surface is connected to the first side surface and the second side surface, the slide seat 15 is slidably arranged on the third side surface, and a total of two interval-arranged slide grooves 1501 are arranged on the slide seat 15. When the slide seat 15 slides downward under the drive of the linear drive source, it drives the reversing rod 8 connected to the first side surface to rotate clockwise, and drives the reversing rod 8 connected to the second side surface to rotate counterclockwise, thereby simultaneously switching the two reversing ball valves 7 from the first position to the second position; when the slide seat 15 slides upward under the drive of the linear drive source, it drives the reversing rod 8 connected to the first side surface to rotate counterclockwise, and drives the reversing rod 8 connected to the second side surface to rotate clockwise, thereby simultaneously switching the two reversing ball valves 7 from the second position to the first position.

The molding cavity 18 is fixedly connected to the lower end of the fixing seat 5 and communicated with the interior of the rotating tube 2, and the discharge nozzle 4 is fixedly connected to the lower end of the molding cavity 18; the outer sleeve 19 is arranged around the outside of the molding cavity 18, and forms an interlayer insulation space 20 with the molding cavity 18. The outer sleeve 19 is provided with one or two connecting channels 1901. When there is one connecting channel 1901, the connecting channel 1901 is suitable for connecting a vacuum pumping device. When there are two connecting channels 1901, one of the connecting channels 1901 is a circulating water inlet, and the other connecting channel 1901 is a circulating water outlet.
