Description

Technical Field

[0001] This utility model relates to the field of color sorter technology, specifically to an easy-to-disassemble and easy-to-clean plastic nozzle plate. Background Technology

[0002] With the continuous development of the color sorter industry, most of the key components of color sorters, such as nozzle plates, have been replaced with engineering plastics. However, if the plastic nozzle plates become clogged or accumulate dirt during use, they are prone to clogging the nozzle holes. Furthermore, it is difficult to rework the air pipes after they have been filled with adhesive, resulting in unnecessary waste.

[0003] Nozzle plates, as a crucial structure for jet output, are commonly used to control the directional injection of compressed gas, thereby precisely driving or sorting impurities, foreign objects, or target materials. With the gradual shift from metal to engineering plastics in nozzle plates, the weight of the components has been significantly reduced, and manufacturing costs have been lowered.

[0004] However, many problems still exist in practical applications: the nozzle orifice often fails due to "material jamming" or foreign object residue, affecting sorting accuracy and operating efficiency; on the other hand, most existing nozzles and nozzle plates adopt adhesive bonding, hot melting or non-removable fixed structures, requiring the entire nozzle assembly to be replaced during maintenance, which is time-consuming, labor-intensive and has many vulnerable parts, resulting in a large maintenance burden and material waste. Utility Model Content

[0005] The purpose of this utility model embodiment is to provide an easy-to-disassemble and easy-to-clean plastic nozzle plate, which aims to solve the technical problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A plastic nozzle plate that is easy to disassemble and clean includes a nozzle fixing plate, on which a plastic nozzle is disposed, and an inner retaining block is disposed inside the plastic nozzle, and the plastic nozzle is movably connected to the nozzle fixing plate through the inner retaining block;

[0008] A duct sealing plate is provided on one side of the nozzle fixing plate, and an eccentric locking block is provided on the duct sealing plate. The duct sealing plate is movably connected to the nozzle fixing plate through the eccentric locking block structure.

[0009] Furthermore, the plastic nozzle is provided with multiple sets of air outlets, which are evenly distributed on the side of the plastic nozzle.

[0010] Furthermore, the nozzle fixing plate is provided with a mounting hole, which is connected to an inner locking block on the plastic nozzle. One end of the inner locking block is hook-shaped and the inner locking block is made of elastic plastic material.

[0011] Furthermore, an air pipe is provided inside the nozzle fixing plate, and the air pipe is positioned between the air pipe sealing plate and the nozzle fixing plate.

[0012] Furthermore, the airway sealing plate is provided with several holes, through which the air pressure inside the nozzle fixing plate is adjusted.

[0013] Furthermore, the number of holes on the air tube sealing plate is the same as the number of air outlets on the plastic nozzle.

[0014] The easily disassembled and easily cleaned plastic nozzle plate provided by this utility model has the following beneficial effects:

[0015] The nozzle mounting plate and nozzle are designed as separate units. When the nozzle becomes clogged or blocked, it can be disassembled and cleaned using a locking mechanism. After cleaning, it can be reinstalled using the locking mechanism, significantly improving the efficiency of after-sales maintenance personnel. Another component, the air hose seal, utilizes a physical eccentric locking mechanism to directly fix the air hose to the nozzle mounting plate without the need for glue bonding, thus further improving efficiency.

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0022] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0023] like Figures 1-4As shown in the figure, the present utility model provides an easy-to-disassemble and easy-to-clean plastic nozzle plate, including a nozzle fixing plate 2. The nozzle fixing plate 2 is characterized in that a plastic nozzle 1 is provided on the nozzle fixing plate 2, and an inner locking block 4 is provided inside the plastic nozzle 1. The plastic nozzle 1 is movably connected to the nozzle fixing plate 2 through the inner locking block.

[0024] A tracheal sealing plate 3 is provided on one side of the nozzle fixing plate 2. An eccentric locking block 5 is provided on the tracheal sealing plate 3. The tracheal sealing plate 3 is movably connected to the nozzle fixing plate 2 through the eccentric locking block structure.

[0025] In this embodiment, the plastic nozzle 1 is a spraying functional component, located above the nozzle fixing plate 2, and employs a split structure to cooperate with the nozzle fixing plate 2. The nozzle fixing plate 2 has a limiting groove for positioning the nozzle. This groove structure utilizes an embedded positioning principle, and through a specific snap-fit ​​geometry, automatically achieves axial and radial limiting fixation when the plastic nozzle 1 is inserted into the groove. After installation, the plastic nozzle 1 can stably maintain the spray angle aligned with the air outlet channel.

[0026] The nozzle fixing plate 2 is provided with a plug-in structure that matches the shape of the inner locking block of the plastic nozzle 1. When the plastic nozzle 1 is inserted, the inner locking block is positioned and locked with the plug or groove through the geometric limiting structure, forming a stable connection; when pulled out, the limiting is released, achieving the purpose of tool-free disassembly and assembly.

[0027] The eccentric locking block 5 structure on the trachea sealing plate 3 replaces the traditional glue-filling fixing method, making the installation and disassembly of the trachea quicker and more convenient, avoiding the problems of difficult air tightness control and difficult later repair caused by glue filling, improving the reusability of components and the reliability of equipment. An eccentric slot is provided on the nozzle fixing plate 2, and the trachea sealing plate 3 is connected to the nozzle fixing plate 2 through the cooperation of the eccentric locking block 5 and the eccentric slot.

[0028] The eccentric locking block 5 structure utilizes the principle of eccentric rotation. After the air tube is inserted, it forms a press-fit fixation with the nozzle fixing plate 2 through rotation or axial compression, creating a physical limiting and sealing effect. The structure is reversible; it can be loosened by rotating in the opposite direction.

[0029] like Figure 1 and Figure 4 As shown, in one embodiment of this utility model, the plastic nozzle 1 is provided with multiple sets of air outlets, which are evenly distributed on the side of the plastic nozzle 1.

[0030] In this embodiment, the air outlet of the plastic nozzle 1 is set to multiple groups and evenly distributed, which can improve the uniformity and coverage of air jet or spray, which is beneficial to improve the operation accuracy and efficiency of the equipment in color sorting, purging and other scenarios. At the same time, it also leaves structural redundancy for multi-point control to adapt to different needs.

[0031] By arranging multiple sets of air outlets 1 at equal intervals on the side of the plastic nozzle 1, each nozzle can perform air jet operation independently or in conjunction. The uniform arrangement not only optimizes the airflow distribution, but also allows for modular adjustment of the number of nozzles to accommodate various nozzle specifications, thereby improving the system's versatility.

[0032] like Figure 1 and Figure 4 As shown, in one embodiment of this utility model, the nozzle fixing plate 2 is provided with an installation hole, which is connected to the inner locking block 4 on the plastic nozzle 1.

[0033] In this embodiment, by providing mounting holes in the nozzle fixing plate 2 and connecting the mounting holes with the inner locking block 4 on the plastic nozzle 1, the nozzle assembly can be quickly inserted and stably positioned. This not only greatly simplifies the nozzle assembly process, but also enables the nozzle to be quickly disassembled and replaced when it is clogged, contaminated or worn, significantly improving the maintenance efficiency and flexibility of the equipment.

[0034] Meanwhile, the slotted connection structure has good reusability, avoiding structural damage and irreversible problems caused by traditional potting or threaded connections, reducing maintenance costs, and enhancing the reliability and maintainability of the nozzle plate assembly.

[0035] like Figure 1 and Figure 4 As shown, in one embodiment of this utility model, an air pipe is provided inside the nozzle fixing plate 2, and the air pipe is disposed between the air pipe sealing plate 3 and the nozzle fixing plate 2.

[0036] In this embodiment, by setting an air pipe inside the nozzle fixing plate 2 and passing the air pipe sealing plate 3, the air supply path is integrated, thereby ensuring gas transmission efficiency, reducing the risk of poor interface or leakage, and improving the continuity and stability of the jet system.

[0037] The pre-reserved ventilation channel in the structure allows the air source to be transmitted from the sealing plate to the nozzle assembly via the air pipe, eliminating the need for additional exposed hose connections. This reduces pipe swaying interference and fatigue wear, and also avoids unstable air supply problems caused by assembly errors.

[0038] like Figure 1 and Figure 4 As shown, in one embodiment of this utility model, the air pipe sealing plate 3 is provided with a plurality of holes, and the air pressure inside the nozzle fixing plate 2 is adjusted through the holes on the air pipe sealing plate 3.

[0039] In this embodiment, the air pipe sealing plate 3 is provided with several holes, which can realize the airflow adjustment inside the nozzle fixing plate 2 according to the specific working conditions, thereby realizing the air pressure ratio or flow control between different nozzles and improving the adaptability and adjustment accuracy of the jet system.

[0040] like Figure 1 and Figure 4 As shown, in one embodiment of this utility model, the number of holes on the air tube sealing plate 3 is the same as the number of air outlets of the plastic nozzle 1.

[0041] In this embodiment, by setting the number of holes on the air tube sealing plate 3 to be the same as the number of plastic nozzles 1, each nozzle can correspond to a separate air supply hole, thereby constructing a one-to-one independent air path system. Several holes are evenly distributed on the air tube sealing plate 3, and the number of holes is consistent with the number of plastic nozzles 1 set on the nozzle fixing plate 2. For example, when there are 10 groups of nozzles 1, there are 10 holes on the air tube sealing plate 3, and each hole forms an air supply connection with the corresponding nozzle 1 in the nozzle fixing plate 2 through an internal air passage or an independent air tube.

[0042] This structural design can significantly improve the accuracy of air supply and control flexibility, avoiding problems such as air pressure fluctuations, uneven air jets, or response delays caused by multiple nozzles sharing an air path.

[0043] The working principle of this utility model is as follows: The nozzle fixing plate 2 has a limiting groove for positioning the nozzle. This groove structure utilizes the principle of embedded positioning and, through a specific buckle geometry, automatically achieves axial and radial limiting and fixing when the plastic nozzle 1 is inserted into the groove. After installation, the plastic nozzle 1 can stably maintain the alignment of the spray angle with the air outlet channel. During long-term use, if the plastic nozzle 1 becomes clogged, accumulates foreign matter, or is blocked by particles, maintenance personnel can quickly remove the plastic nozzle 1 by releasing the limiting groove, clean it, and then reinsert it in its original position for use. No tools or destructive disassembly are required, significantly improving the convenience and efficiency of maintenance.

[0044] The trachea sealing plate 3 features a relatively asymmetrical internal cavity structure. After the trachea is inserted, it is pressed against the edge of the mounting hole on the nozzle fixing plate 2 by rotation or pushing, achieving physical restraint and sealing. This method ensures the airtightness of the trachea connection and eliminates the processing complexity and rework difficulties associated with using glue or potting. If the trachea needs replacement or repair, it can be quickly disassembled by simply releasing the locking mechanism, greatly improving overall maintenance efficiency and reusability.

[0045] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
