Description

Technical Field

[0001] The utility model relates to the technical field of material spraying, in particular to a uniform spraying device. Background Art

[0002] At present, it is difficult for the existing spraying devices to achieve uniform spraying of materials. Specifically, when the fluid material enters the spray pipe, the material near one end of the feed port forms a greater pressure in the pipe. As the material continues to enter the pipe, the pressure formed in the pipe will gradually decrease. Based on the above principle, the spray holes at different positions on the spray pipe will have different material spraying amounts, which makes it difficult to spray the material uniformly. Utility Model Content

[0003] The purpose of the utility model is to address the technical problems existing in the background technology and to propose a uniform spray device, including a spray assembly, the spray assembly including a first spray pipe and a second spray pipe, the first spray pipe is sleeved in the second spray pipe, a spray chamber is formed between the first spray pipe and the second spray pipe, the first spray pipe is provided with a first spray hole, and the second spray pipe is provided with a second spray hole.

[0004] Furthermore, the first spray pipe includes a plurality of feed ports.

[0005] Furthermore, feed ports are arranged at both ends of the first spray pipe.

[0006] Furthermore, a plurality of first spray holes are provided, and the apertures of the first spray holes gradually decrease from the middle of the first spray pipe to both ends of the first spray pipe.

[0007] Furthermore, the aperture size specification of the second spray hole should meet the requirement that: "the material entering the spray chamber cannot be discharged from the second spray hole without applying additional pressure thereto".

[0008] Furthermore, it also includes a driving mechanism, which is connected to the spray assembly and is used to drive the spray assembly to move.

[0009] Compared with the prior art, the utility model has the following beneficial technical effects: it can be understood that, since the first spray pipe of the utility model is provided with a plurality of feed ports, the material can enter the first spray pipe through different feed ports to eliminate the influence of the pressure difference as much as possible, thereby ensuring that the amount of material sprayed from different first spray holes is as consistent as possible;

[0010] Furthermore, since a spray chamber is formed between the first spray pipe and the second spray pipe, the material sprayed from the first spray hole will enter the spray chamber, and the spray chamber can further eliminate the pressure difference of the material entering the first spray pipe, so as to realize uniform spraying of the material from the second spray hole, with a simple structure and ingenious arrangement;

[0011] Furthermore, since the diameter of the spray hole of the first spray pipe gradually decreases from the middle to the two ends, when the material enters the first spray pipe from the two ends of the first spray pipe, the spray holes close to the two ends of the first spray pipe are smaller, thereby reducing the spray amount of the material at the near end, and the spray holes far from the two ends of the first spray pipe are larger, thereby increasing the spray amount of the material at the far end, so as to further ensure that the amount of material sprayed from the first spray hole remains consistent;

[0012] Furthermore, because the second spray hole can make "the material entering the spray chamber unable to be discharged from the second spray hole without applying additional pressure to it", when the material sprayed from the first spray pipe enters the spray chamber, the material will not be immediately discharged through the second spray hole. When the material in the spray chamber is full, as the material continues to enter the spray chamber, the material will be sprayed out through the second spray hole under the action of pressure, so that the material is sprayed evenly under the state of balanced pressure;

[0013] In summary, the uniform spraying device of the utility model can ensure that the spraying amount of the material remains consistent when it is sprayed through the second spray hole, thereby achieving uniform spraying of the material. BRIEF DESCRIPTION OF THE DRAWINGS

In addition, the terms "first", "second", etc. are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, features defined as "first", "second", etc. may explicitly or implicitly include one or more features. In the description of the present utility model, unless otherwise specified, "multiple" means two or more.

[0018] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or a specific connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0019] The specific embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0020] like Figure 1-Figure 2 As shown, the utility model proposes a uniform spraying device, including a spray assembly 1, the spray assembly 1 includes a first spray pipe 11 and a second spray pipe 12, the first spray pipe 11 is sleeved in the second spray pipe 12, a spray chamber 13 is formed between the first spray pipe 11 and the second spray pipe 12, the first spray pipe 11 includes a plurality of first spray holes 111 and a plurality of feed ports 112, and the second spray pipe 12 is provided with a plurality of second spray holes 121.

[0021] It can be understood that since the first spray pipe 11 of the utility model is provided with a plurality of feed ports 112, the material can enter the first spray pipe 11 through different feed ports 112 to eliminate the influence of the pressure difference as much as possible, thereby ensuring that the amount of material sprayed from different first spray holes 111 is as consistent as possible. It can be understood that the feed port 112 can be provided in plurality, and the position of the feed port 112 should include but is not limited to being provided at both ends of the first spray pipe 11. Furthermore, the material sprayed from the first spray hole 111 will enter the spray chamber, and the spray chamber 13 can further eliminate the pressure difference of the material entering the first spray pipe 11, so as to realize the uniform spraying of the material from the second spray hole 121. The structure is simple and the arrangement is ingenious.

[0022] Furthermore, in the present embodiment, the first spray holes 111 are arranged along the length direction of the first spray pipe 11, and the aperture of the first spray holes 111 gradually decreases from the middle of the first spray pipe 11 to the two ends of the first spray pipe 11. Through the above arrangement, since the aperture of the first spray holes 111 gradually decreases from the middle to the two ends, when the material enters the first spray pipe 11 from the two ends of the first spray pipe 11, the material near the two ends of the first spray pipe 11 has a smaller aperture, thereby reducing the spraying amount of the material at the near end, and the material far away from the two ends of the first spray pipe 11 has a larger aperture, thereby increasing the spraying amount of the material at the far end, so as to ensure that the amount of material sprayed from the first spray hole 111 remains consistent.

[0023] Furthermore, in this embodiment, the aperture size specification of the second spray hole 121 should meet the requirement that: "the material entering the spray chamber 13 cannot be discharged from the second spray hole 121 without applying additional pressure thereto".

[0024] It can be understood that the material sprayed from the first spray pipe 11 will enter the spray chamber 13, and the material will not be discharged through the second spray hole 121 at this time. When the material in the spray chamber 13 is filled, as the material continues to enter the spray chamber 13, under the action of pressure, the material will be sprayed through the second spray hole 121. That is, through the above-mentioned structural setting, the utility model can further ensure that the material is evenly sprayed under a pressure-balanced state by setting the first spray pipe 11, the second spray pipe 12 and the spray chamber 13, and cooperating with the first spray hole 111 and the second spray hole 121.

[0025] Furthermore, in this embodiment, the utility model also includes a driving mechanism 2, which is connected to the spray assembly 1 to drive the spray assembly 1 to move. Specifically, the driving mechanism 2 includes a driving motor 21, a connecting plate 22 and a sliding assembly 23. The sliding assembly 23 is arranged in a strip shape and in pairs. The sliding assembly 23 is provided with a sliding groove on one side. The two ends of the connecting plate 22 are respectively slidably connected to the sliding groove of the sliding assembly 23. The driving motor 21 is connected to the connecting plate 22, and the spray assembly 1 is connected to the connecting plate 22. Through the above-mentioned structural setting, when the driving motor 21 is in operation, it will drive the connecting plate 22 to slide relative to the sliding assembly 23, so as to realize the movement of the spray assembly 1 relative to the sliding assembly 23. Specifically, a transmission member 221 is provided at the top of the connecting plate 22, and a plurality of gear units 2212 are provided on the transmission member 221. The gear units 2212 are arranged along the extension direction of the sliding assembly 23. The transmission end of the driving motor 21 is meshed and connected with the gear unit 2212. When the driving motor 21 rotates, the kinetic energy will be transmitted to the gear unit 2212 to drive the transmission member 221 to perform reciprocating motion, so as to realize the sliding of the connecting plate 142 relative to the sliding assembly 143.

[0026] Furthermore, the driving mechanism 2 further includes a lifting mechanism 24, which is connected to the spray assembly 1 and the connecting plate 22 respectively, and is used to drive the spray assembly 1 to move up and down. Specifically, the lifting mechanism 24 of this embodiment can be a lifting cylinder or other device that can realize the up and down movement of the spray assembly 1. Through the above structural setting, the spray assembly 1 of the utility model can realize lateral and longitudinal movement under the action of the driving mechanism 2 to expand the spraying range.

[0027] The above are one or more implementation methods provided in combination with specific content, and it is not intended that the specific implementation of the utility model is limited to these descriptions. Any method, structure, etc. similar to or identical to the method, structure, etc. of the utility model, or any technical deduction or replacement based on the concept of the utility model, shall be deemed to be within the protection scope of the utility model.
