[0033] Example 1

[0034] This embodiment provides a spray structure 10.

[0035] Please see Figure 1 and combined Figure 2 The spray structure 10 includes a spray body 11, an air distribution manifold 20, a pressure regulating valve 50, and at least one spray component 12.

[0036] The spray body 11 has a liquid flow channel 110; each spray component 12 includes a cylinder 123 and a nozzle 124 that are connected in a mating manner; in the same spray component 12, the cylinder 123 and the nozzle 124 are located on both sides of the spray body 11, and the cylinder 123 and the nozzle 124 in the same spray component 12 are connected to the liquid flow channel 110 in the spray body 11; each cylinder 123 in the spray component 12 is connected to a reversing valve 40.

[0037] All directional valves 40 are connected to the air distribution manifold 20, and the pressure regulating valve 50 is connected to the air distribution manifold 20.

[0038] In some alternative embodiments, in the same aerosol component 12, the cylinder 123 and the nozzle 124 are located on the upper and lower sides of the aerosol body 11, respectively.

[0039] In some alternative embodiments, a conventional cylinder structure can be referenced. In this embodiment, cylinder 123 includes a piston rod 1231, a piston chamber 1232, and a cylinder barrel connected in sequence. The end of the cylinder barrel away from the piston rod 1231 is connected to the nozzle 124. Under the action of cylinder 123, the liquid in the liquid flow channel 110 enters the nozzle 124 and is sprayed out from the lower end of the nozzle 124.

[0040] In some alternative embodiments, the liquid material can be chocolate liquid. In other embodiments, it can be other liquid materials, such as paste, as needed.

[0041] In some alternative embodiments, the spray structure 10 further includes a control valve 30 for controlling the flow rate of the liquid material, one end of the liquid material channel 110 is connected to the feed pipe 113, and the control valve 30 is disposed on the feed pipe 113.

[0042] For example, the control valve 30 mentioned above can be a pneumatic angle valve. By adjusting the opening of the pneumatic valve, the flow rate or velocity of the liquid in the liquid flow channel 110 can be controlled.

[0043] In some alternative embodiments, the spray structure 10 also includes a muffler 41 disposed on the reversing valve 40.

[0044] By installing a silencer 41 on the reversing valve 40, the noise generated during operation can be reduced or decreased.

[0045] In some optional embodiments, the spray body 11 includes a first spray body 111 and a second spray body 112, wherein the liquid flow channel 110 of the first spray body 111 is connected to the liquid flow channel 110 of the second spray body 112.

[0046] For example, a first spray body 111 and a second spray body 112 are spaced apart. One end of the first spray body 111 (e.g., the left end) serves as the feed end of the entire liquid flow channel 110, and the other end of the first spray body 111 (e.g., the right end) is connected to one end of the second spray body 112 (e.g., the right end). The other end of the second spray body 112 (e.g., the left end) serves as the discharge end of the entire liquid flow channel 110. The first spray body 111 and the second spray body 112 can be connected via an arc-shaped pipe 115. Correspondingly, the feed end of the entire liquid flow channel 110 is connected to a feed pipe 113, and the discharge end of the entire liquid flow channel 110 is connected to a discharge pipe 114.

[0047] In some optional embodiments, there are multiple aerosol components 12, which are distributed in multiple groups. That is, the aerosol components 12 contained in the entire aerosol structure 10 are distributed in multiple groups. Each group of aerosol components 12 includes a first aerosol component 121 and a second aerosol component 122. The first aerosol component 121 is connected to the first aerosol body 111, and the second aerosol component 122 is connected to the second aerosol body 112. The cylinders 123 of the same group of aerosol components 12 are connected to a reversing valve 40.

[0048] Taking the spray structure 10 as an example, which includes n sets of spray elements 12, that is, the spray structure 10 includes a total of n first spray elements 121 and n second spray elements 122, and the number of reversing valves 40 is also n. One reversing valve 40 corresponds to one set of spray elements 12; each reversing valve 40 is simultaneously connected to the first spray element 121 and the second spray element 122 in its corresponding set of spray elements 12.

[0049] In some of the listed embodiments, the first spraying body 111 and the second spraying body 112 are spaced apart in the front-to-back direction, and each of the first spraying body 111 and the second spraying body 112 is provided with nine cylinders 123; the two cylinders 123 distributed in the front-to-back direction can be connected to a reversing valve 40 at the same time. Based on this, the reversing valve 40 can simultaneously control the working state of two cylinders 123 in the same group of spraying components 12, for example, controlling the two cylinders 123 to spray material at the same time, or controlling one of the two cylinders 123 to spray material while the other does not spray material.

[0050] In some optional embodiments, the piston chamber 1232 of each cylinder 123 has a first air passage 1233 and a second air passage 1234, and the reversing valve 40 cooperating with the cylinder 123 is selectively connected to the first air passage 1233 and the second air passage 1234. In actual operation, air connectors can be provided at the first air passage 1233 and the second air passage 1234, and the reversing valve 40 is connected to the air connectors to control the extension (which can be understood as pressing down) and retraction (which can be understood as raising) of the piston rod 1231 in the cylinder 123. The amount of liquid entering the nozzle 124 from the liquid flow channel 110 can be adjusted by the up and down movement of the piston rod 1231.

[0051] In some alternative implementations, the air distribution manifold 20 has a plurality of air ports 21, each air port 21 being connected to a reversing valve 40.

[0052] In some alternative embodiments, the air distribution manifold 20 extends along the length of the spray body 11, and the pressure regulating valve 50 is located at the end of the air distribution manifold 20 near the discharge pipe 114. This arrangement allows most of the control components to be concentrated at the same end of the equipment, facilitating management.

[0053] In some alternative implementations, the pressure value of the pressure regulating valve 50 can be set according to actual needs, thereby ensuring that the pressure in the air distribution manifold 20 is stable and meets the usage requirements.

[0054] In some alternative embodiments, the spray structure 10 may also include a central valve island 60, which is connected to all the directional valves 40 to control all the directional valves 40.

[0055] The aforementioned central valve island 60 can be a pneumatic-electric integrated control component, which can control the switching time and duration of all reversing valves 40 through air pipes. The reversing valves 40 are connected to the cylinders 123, thereby controlling the corresponding actions of the cylinders 123.

[0056] Continuing from the above, the design of the air distribution manifold 20 and pressure regulating valve 50 ensures stable air pressure output, enabling multiple cylinders 123 to operate stably under air pressure. The central valve island 60 allows for effective control of multiple directional valves 40, including directional switching time and duration, facilitating synchronous or independent operation of multiple cylinders 123. Combined with the control valve 30 controlling the flow rate of the liquid entering the liquid channel 110, this ultimately achieves uniform and consistent material spraying from multiple nozzles 124, resulting in excellent overall material discharge stability.

[0057] By utilizing the aforementioned spraying structure 10, the stability of the spraying amount at each stage can be effectively ensured, preventing inconsistent spraying amounts and achieving stable overall material output. The pressure inside the air distribution manifold 20 is adjusted by the pressure regulating valve 50. When the central valve island 60 receives an external signal, it controls the operation of the reversing valve 40 by charging or venting air, thereby controlling the action of the cylinder 123.

[0058] In some alternative embodiments, the bottom of the spraying body 11 may also be provided with wheels 70. By providing wheels 70, the movement of the entire spraying structure 10 can be facilitated.

[0059] Example 2

[0060] This embodiment provides a spraying device 100, such as... Figure 2 As shown, it includes a main air source 81, a spray source 82, and the spray structure 10 in Example 1.

[0061] The main air source 81 is connected to the pressure regulating valve 50 in the spray structure 10; the spray source 82 is connected to the liquid flow channel 110 in the spray structure 10.

[0062] In some alternative embodiments, the spraying device 100 also includes a control box 90, in which a central valve island 60 is disposed.

[0063] In the spraying equipment 100, the main air source 81, pressure regulating valve 50, air distribution manifold 20, reversing valve 40, and cylinder 123 are connected in sequence to form a gas channel. The spraying source 82, control valve 30, feed pipe 113, liquid flow channel 110, and spray nozzle 124 are connected in sequence to form a liquid flow channel.

[0064] For example, the installation process of the above-mentioned spraying device 100 may include:

[0065] S1: Install the cylinder 123 and the nozzle 124 onto the spray body 11.

[0066] S2: Fix the air distribution manifold 20 and the pressure regulating valve 50 to the spray body 11, connect the pressure regulating valve 50 and the air distribution manifold 20 with an air pipe, and connect the pressure regulating valve 50 to the main air source 81 with an air pipe.

[0067] S3: Install each reversing valve 40 onto the air distribution manifold 20 and install the silencer 41. Connect the air distribution manifold 20, the reversing valve 40 and the cylinder 123 that it works with using an air pipe. Connect the reversing valve 40 to the central valve island 60 using an air pipe.

[0068] S4: Secure the control valve 30 to the feed pipe 113, for example, by using a pipe clamp to secure the control valve 30 to the feed pipe 113.

[0069] In summary, the spraying device 100 provided by this utility model is connected to multiple directional valves 40 simultaneously through a central valve island 60. The central valve island 60 can control the switching time and duration of each directional valve 40, and control the action of the corresponding cylinder 123 by controlling the directional valve 40. At the same time, an air tank is set to maintain stable compressed air pressure, and a pressure regulating valve 50 is set to adjust the pressure in the air tank. In addition, a control valve 30 is set to control the flow rate of the liquid material, thereby achieving uniform and stable spraying of multiple nozzles 124.

[0070] The above description is only a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
