Description

Technical Field

[0001] The present application relates to the field of spraying, and in particular to an external spraying device. Background Art

[0002] In the production process of pet puffed food, spraying equipment is typically used to evenly spray liquid additives, such as oils, vitamins, and minerals, onto the surface of the puffed food. These spraying devices are widely used in industrial applications, mainly including manual spraying and automatic spraying. However, traditional spraying devices have some obvious shortcomings, such as slow spraying speed, uneven spraying, and complicated operation. These problems not only affect production efficiency, but may also lead to unsatisfactory spraying effects, affecting the quality of pet puffed food.

[0003] In order to achieve fast and uniform spraying, the existing technology has proposed a variety of improvement schemes. For example, the use of high-pressure spray technology to increase the spraying speed and uniformity by increasing the injection pressure; or the use of rotary spray technology to expand the spray coverage by rotating the nozzle, thereby improving the uniformity and efficiency of the spraying. In addition, there are some automatic spraying systems that improve the spraying effect by precisely controlling the spraying parameters such as spraying time, spraying angle and flow rate. These existing technical solutions have solved the shortcomings of traditional spraying devices to a certain extent and improved the spraying efficiency and uniformity.

[0004] Although the existing spraying devices have achieved fast and uniform spraying to a certain extent, their design and performance still have some defects. For example, although high-pressure spray technology has increased the spraying speed, it is easy to produce splashing during the spraying process, resulting in waste of resources and uneven spraying; although the automatic spraying system can accurately control the spraying process, its complex control system is prone to failure, which increases the difficulty and cost of maintenance. In addition, in actual applications, these existing technologies may still lead to unstable spraying effects due to equipment aging or improper operation, making it difficult to ensure the spraying quality of each batch of pet puffed food. Therefore, there is an urgent need for a new type of spraying device that can achieve efficient and uniform spraying to meet the spraying needs in the production process of pet puffed food.

[0032] The following is combined with Figure 1-4 , some embodiments of the present application are described in detail. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0033] The embodiment of the present application provides an external spraying device 100 for pet puffed food, comprising a flow control assembly 1 , wherein the external spraying device comprises a suction device 2 and a pump assembly 3 arranged in parallel;

[0034] The pump body assembly 3 includes a valve assembly 4, an elastic member 5, a pump room 6 and a piston 7. The pump room 6 includes an injection portion 8 and an absorption portion 9. The injection portion 8 is provided with a first through hole 10. The valve assembly 4 is provided in the first through hole 10, and the valve assembly 4 is electrically connected to the flow control assembly 1. The piston 7 and the valve assembly 4 are arranged in parallel. The piston 7 partially extends into the first through hole 10. There is a gap between the piston 7 and the valve assembly 4, and the piston 7 has an injection port 16 facing the valve assembly 4. The elastic member 5 is annularly arranged on the piston 7 with one end abutting the piston 7 and the other end abutting the injection portion 8.

[0035] The suction device 2 includes a suction filter 12 and a suction pipe 13 . The suction portion 9 defines a second through hole 11 communicating with the first through hole 10 . One end of the suction pipe 13 is disposed in the second through hole 11 , and the other end is fixedly connected to the suction filter 12 .

[0036] Specifically, the pump body assembly 3 realizes an efficient and accurate spraying process through the coordinated work of the piston 7, the elastic member 5 and the valve assembly 4. The suction device 2 ensures the continuous supply of raw materials. The injection portion 8 in the pump body assembly 3 is provided with a first through hole 10. The valve assembly 4 is arranged in the first through hole 10 and is electrically connected to the flow control assembly 1. The piston 7 partially extends into the first through hole 10 and has a spray port 16 facing the valve assembly 4. The elastic member 5 is annularly arranged on the piston 7 and acts between the piston 7 and the injection portion 8 to ensure the reset function of the piston 7. At the same time, in the suction device 2, the suction filter 12 is fixedly connected to the suction pipe 13, which can effectively filter impurities and connect to the pump body assembly 3 through the second through hole 11. The entire device The operating process is as follows: when the flow control assembly 1 is started, the piston 7 in the pump body assembly 3 starts to reciprocate under the control of the valve assembly 4, and the liquid spraying amount is controlled by the opening and closing of the valve. The suction device 2 continuously sucks the liquid through the suction filter 12 and transports it to the pump room 6, and finally sprays the liquid additive from the injection port 16. The entire equipment can be used on the pet puffed food production line, and is particularly suitable for efficient and precise spraying of additives such as oils, vitamins and minerals. The application scenarios include large-scale pet puffed food production lines and production processes that require precise spraying of each particle. This design has the advantages of fast and uniform spraying, which solves the problems of slow and uneven spraying in traditional equipment.

[0037] In a specific embodiment, the external spraying device includes a nozzle assembly 14, and the nozzle assembly 14 also includes a nozzle cone 15. The nozzle 17 is provided at an end of the injection portion 8 away from the piston 7 and is connected to the piston 7 by a housing.

[0038] Specifically, the nozzle assembly 14 comprises a nozzle cone 15 and a nozzle 17. The nozzle cone 15 is located at the end of the spray section 8 away from the piston 7 and is fixed to it by a clamp. The nozzle cone 15 guides the spray direction and ensures uniform liquid discharge from the nozzle 17. The clamping mechanism facilitates removal and replacement of the nozzle assembly 14, further reducing maintenance and increasing the service life of the equipment. The conical structure of the nozzle cone 15 increases liquid spray accuracy and prevents the sprayed liquid from drifting after leaving the nozzle 17, thereby improving spray efficiency and avoiding resource waste. Furthermore, the design of the nozzle cone 15 expands the spray range, making it suitable for scenarios requiring large-area coverage, such as large-scale liquid additive spraying in pet food production lines.

[0039] In a specific embodiment, the nozzle assembly 14 includes a nozzle 17 and a nozzle tip 18, wherein the nozzle tip 18 is clamped to the end of the injection portion 8 away from the piston 7, and the nozzle tip 18 is arranged in parallel with the nozzle cone 15, and the nozzle tip 18 is in close contact with the nozzle cone 15;

[0040] The nozzle 17 is arranged in parallel with the valve assembly 4 with a gap therebetween. The nozzle 17 is fixedly connected to the port of the injection portion 8 away from the piston 7. The nozzle tip 18 is provided with a slot 19. The nozzle 17 is arranged in the slot 19 and the nozzle tip 18 wraps the nozzle 17.

[0041] Specifically, the nozzle tip 18 is arranged in parallel with the nozzle cone 15 and is fixed to the injection part 8 by clamping. The nozzle tip 18 wraps the nozzle 17 and is provided with a card slot 19. This structural design can enhance the stability and air tightness of the nozzle 17. The design of the card slot 19 facilitates the installation and replacement of the nozzle tip 18, avoids leakage of the spraying liquid, and ensures the continuity and uniformity of the spraying process. The wrapping design of the nozzle tip 18 helps to concentrate the spray pressure of the spraying liquid, so that the sprayed liquid covers a wider area. It is particularly suitable for process scenarios requiring high-pressure spraying, such as when spraying high-viscosity liquid, to ensure that the liquid can be evenly distributed on the surface of the pet puffed food, reducing the problem of uneven coverage.

[0042] In a specific embodiment, the nozzle tip 18 is a hollow conical structure, and the direction of the central axis of the conical structure set away from the piston 7 is defined as the first direction. It has an open surface along the first direction, and the inner wall of the nozzle tip 18 is provided with an annular body 21 uniformly arrayed along the first direction. The inner diameter of the annular body 21 increases step by step along the opening direction of the conical structure.

[0043] Specifically, the nozzle tip 18 is designed as a hollow conical structure, with evenly arranged annular bodies 21 inside. The inner diameter of the annular body 21 increases step by step along the opening direction of the cone. This design can effectively guide the flow of liquid, so that the liquid diffuses layer by layer during spraying, thereby improving the uniformity of spraying. The hollow design of the conical structure not only increases the spraying area, but also reduces the resistance during the spraying process, ensuring that the sprayed liquid can be quickly and evenly distributed on the surface of the pet puffed food. It is suitable for large-scale production scenarios, especially processes that require wide coverage spraying, and can effectively reduce liquid waste and improve production efficiency.

[0044] In a specific embodiment, the external spraying equipment includes a particle container 22 , which is located below the pump body assembly 3 in the vertical direction, and the particle container 22 wraps the suction device 2 and is fixedly connected to the suction part 9 .

[0045] Specifically, the container is located below the pump body assembly 3 in the vertical direction and is fixedly connected to the suction device 2 and the suction part 9. This layout design helps to achieve smooth flow of materials under the action of gravity. The setting of the particle container 22 avoids the sedimentation of particulate matter in the liquid, thereby improving the working stability of the spraying equipment. The particle container 22 also provides sufficient storage space to accommodate a certain amount of liquid additives, so that the equipment can continue to operate for a long time. It is suitable for pet puffed food production lines that require continuous spraying operations, effectively reducing downtime and manual intervention, and improving production efficiency.

[0046] In a specific embodiment, the external spraying device includes a spring member 23 . The spring member 23 is disposed in the first through hole 10 , with one end abutting against the nozzle 17 and the other end abutting against the valve assembly 4 .

[0047] Specifically, the spraying equipment adds a spring member 23, which is located in the first through hole 10, with one end abutting the nozzle 17 and the other end abutting the valve assembly 4. The function of the spring member 23 is to help the piston 7 and the nozzle 17 to quickly reset after spraying is completed, ensuring that the spraying amount can be accurately controlled each time spraying. The elastic force of the spring member 23 provides a reliable reset mechanism, prevents lag during the spraying process, and ensures the spraying efficiency of the equipment. This design is particularly suitable for high-frequency spraying process scenarios. When the spraying rhythm is fast, it can ensure stable operation of the equipment and extend its service life.

[0048] In a specific embodiment, the suction portion 9 defines a third through hole 24 parallel to the second through hole 11 , and the third through hole 24 connects the particle container 22 and the first through hole 10 .

[0049] Specifically, the third through hole 24 is parallel to the second through hole 11, connecting the particle container 22 and the first through hole 10. The design of the third through hole 24 enables liquid and particulate matter to be more smoothly transported from the particle container 22 to the pump body assembly 3, reducing liquid retention and blockage. The addition of this channel further improves the working efficiency of the equipment, and is particularly suitable for spraying equipment that runs for a long time. It can ensure the continuous and uniform flow of liquid, avoid downtime caused by equipment failure or blockage during the production process, and make the spraying process more stable and reliable.

[0050] In a specific embodiment, the external spraying device includes a motor assembly 25 , one end of the motor assembly 25 is fixedly connected to the flow control assembly 1 , and the other end of the motor assembly 25 is fixedly connected to the pump body assembly 3 .

[0051] Specifically, the motor assembly 25 provides power drive by connecting with the flow control assembly 1 and the pump body assembly 3 to achieve precise control of the spraying speed and flow. The motor assembly 25 can adjust the spraying speed and time according to production needs to ensure that the equipment adapts to different types of liquids and different spraying requirements. The automated control of the motor assembly 25 reduces manual intervention and significantly improves production efficiency. It is particularly suitable for large-scale industrial production scenarios and can maintain efficient and stable spraying operations under complex process conditions, reduce operational errors and improve the quality of finished products.

[0052] In a specific embodiment, the external spraying equipment includes an outer shell 26 , and the flow control assembly 1 , the pump assembly 3 , the motor assembly 25 and the suction device 2 are all disposed in the outer shell 26 .

[0053] Specifically, the outer shell 26 wraps the flow control assembly 1, the pump body assembly 3, the motor assembly 25 and the suction device 2, providing protection. The design of the outer shell 26 can effectively prevent dust and liquid from entering the interior of the equipment, reducing damage to the internal components of the equipment. In addition, the modular design of the outer shell 26 facilitates the installation and maintenance of the equipment and is suitable for use in complex industrial environments. The protective effect of the outer shell 26 can also extend the service life of the equipment and reduce equipment failures caused by external factors.

[0054] In a specific embodiment, the outer shell 26 defines a spray hole 27 , and the nozzle assembly 14 is disposed in the outer shell 26 and partially extends out of the spray hole 27 .

[0055] Specifically, a spray hole 27 is opened on the outer shell 26, and the nozzle assembly 14 partially extends out of the outer shell 26. The spray hole 27 ensures that the nozzle assembly 14 can move freely and spray accurately. The outer shell 26 protects the nozzle assembly 14 from external interference through the spray hole 27, ensuring the stability of the spraying process. The design of the spray hole 27 enables the nozzle assembly 14 to be accurately positioned and operated, avoiding liquid overflow or splashing during the spraying process. It is suitable for high-precision spraying process scenarios, can improve the overall spraying quality and reduce resource waste.

[0056] The above is only an implementation method of the present application. It should be pointed out that for ordinary technicians in this field, improvements can be made without departing from the creative concept of the present application, but these all fall within the scope of protection of the present application.
