Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of pneumatic jet gun head guide shrouds, specifically a porous honeycomb guide shroud for pneumatic jet gun heads. Background Technology
[0002] In pneumatic jetting operations, the jetting nozzle is a key component for mixing and outputting materials and gas, and its performance directly affects the efficiency and stability of the entire pneumatic conveying system.
[0003] Existing spray nozzles are prone to problems such as uneven air-material distribution, unstable spray direction, and airflow turbulence caused by external interference when spraying air and material, which reduces the accuracy and effect of material conveying. There may already be technical solutions to solve the above-mentioned technical problems. In view of this, this case aims to provide a replacement or alternative technical solution. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides a porous honeycomb guide shroud for pneumatic jetting gun heads. This solves the technical problems of uneven gas-material distribution, unstable jetting direction, and airflow turbulence caused by external interference when existing jetting gun heads eject gas, thereby reducing the accuracy and effectiveness of material conveying.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a multi-hole honeycomb guide shroud for a pneumatic jet gun head, comprising two cylindrical guide shrouds, with two first flanges mounted on the opposite walls of the two cylindrical guide shrouds, and the two first flanges being fixedly connected by a number of bolts. One of the cylindrical guide shrouds is fitted with a first grid plate, and the other cylindrical guide shroud is fitted with two connecting rods. An assembly block is fitted between the two connecting rods. A micro servo motor is embedded in one side wall of the assembly block, a sealing plate is mounted on the drive end of the micro servo motor, and a second grid plate is mounted on the side wall of the sealing plate.
[0006] Preferably, a connecting cover is fitted on the side wall of another cylindrical shroud.
[0007] Preferably, a second flange is fitted on the side wall of one of the cylindrical shrouds.
[0008] Preferably, the two cylindrical air guides are respectively fitted with rubber sealing layers on their opposing wall surfaces.
[0009] Preferably, a tapered guide block is assembled on the other side wall of the assembly block.
[0010] Preferably, a third flange is fitted on the side wall of the connecting cover.
[0011] Beneficial effects
[0012] This invention provides a porous honeycomb guide shroud for pneumatic jetting gun heads. It offers the following advantages: This device incorporates honeycomb baffles with dynamically adjustable apertures within the guide shroud, enabling a more uniform mixing of air and material in a shorter time and smaller space. This significantly improves the quality and stability of air-material conveying and effectively suppresses turbulence and fluctuations during the jetting process. Through precise guidance and control of the air-material flow, the impact of external interference on the jetting effect is reduced, ensuring a consistently stable and continuous jetting process. This enhances the reliability and repeatability of the pneumatic conveying system, thus solving the problems of uneven air-material distribution, unstable jetting direction, and turbulent airflow caused by external interference in existing jetting gun heads, which reduce the accuracy and effectiveness of material conveying.

Detailed Implementation
[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0018] Those skilled in the art should connect all electrical components and their compatible power supplies in this case via wires, and should select appropriate controllers according to actual conditions to meet control requirements. The specific connection and control sequence should refer to the working principle described below, where the electrical components are connected in sequence. The detailed connection methods are well-known in the art. The following mainly introduces the working principle and process, without explaining the electrical control.
[0019] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0020] Example: Refer to Figure 1-3 The pneumatic jet nozzle features a multi-hole honeycomb-type flow guide, comprising two cylindrical flow guides 1. Two first flanges 2 are mounted on the opposing walls of the two cylindrical flow guides 1, and the two first flanges 2 are fixedly connected by several bolts 3. One cylindrical flow guide 1 contains a first mesh plate 4, and the other cylindrical flow guide 1 contains two connecting rods 5. An assembly block 6 is mounted between the two connecting rods 5. A micro servo motor 7 is embedded in one side wall of the assembly block 6, and a sealing plate 8 is mounted on the drive end of the micro servo motor 7. A second mesh plate 9 is mounted on the side wall of the sealing plate 8. A connecting cover 10 is mounted on the side wall of the other cylindrical flow guide 1. A second flange 11 is mounted on the side wall of one of the cylindrical flow guides 1. Rubber sealing layers 12 are embedded in the opposing walls of the two cylindrical flow guides 1. A conical flow guide block 13 is mounted on the other side wall of the assembly block 6. A third flange 14 is mounted on the side wall of the connecting cover 10.
[0021] The specific working principle is as follows:
[0022] The workers first assemble two cylindrical guide shields 1 by connecting them with the first flange 2. After assembly, they are then fixed together with several bolts 3. After fixing, the rubber sealing layers 12 installed on the opposing walls of the two cylindrical guide shields 1 are tightly fitted together for sealing. After assembly, they are connected to the spray head through the third flange 14 installed on the connecting cover 10, and then connected to the delivery pipeline through the second flange 11. After preparation, the workers control the operation through the programmable controller installed on it. The micro servo motor 7 installed in the assembly block 6 between the connecting rods 5 drives the sealing plate 8 installed on its drive end to rotate. The second grid plate 9 rotates accordingly, and the openings on the rotating second grid plate 9 intersect parallel to the openings on the first grid plate 4, thereby increasing the number of air vents and increasing the airflow bundle. The micro servo motor 7 drives the sealing plate 8 to rotate and reset, so that the openings on the first grid plate 4 and the second grid plate 9 match and correspond, reducing the airflow bundle. The amount of airflow bundle can be controlled in real time, which is highly flexible. The cylindrical guide shroud 1 helps the air material maintain a relatively stable flow rate and direction inside, reducing the air material deviation caused by the shape of the guide shroud, ensuring that the air material is sprayed out evenly along the axial direction, and achieving a large-area and uniform spraying effect. The conical guide block 13 ensures the stability and smoothness of the airflow.
[0023] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
