Description

Technical Field

[0001] This utility model relates to the field of PE pipe masterbatch production technology, specifically a dustproof feeding auxiliary pipe for PE pipe masterbatch production. Background Technology

[0002] Color masterbatch is a mixture of resin and a large amount of pigment (up to 50%) or dye to form a high concentration of color. Color masterbatch, also known as color seed, is an aggregate made by uniformly loading an extraordinary amount of pigment or dye into resin. During processing, a small amount of color masterbatch is mixed with uncolored resin to achieve the designed pigment concentration of colored resin or product.

[0003] In the prior art, the abstract of the utility model patent with patent application number CN218706004U is as follows: This utility model discloses a dustproof feeding auxiliary pipe for the production of pipe masterbatch, including a first connecting seat for connecting to the discharge hopper of the pipe masterbatch production equipment; a corrugated pipe for facilitating the adjustment of the length of the pipe and also serving as a dustproof function; and a second connecting seat for facilitating the discharge of materials and connected to the bottom of the corrugated pipe. This utility model incorporates a fixed receiving mechanism that covers the opening of the cloth bag with a first and a second fixing ring. Anti-slip protrusions then engage and limit the sleeve at the bag opening. Simultaneously, an arc-shaped rod, in conjunction with a support rod, pushes the inner wall of the bag outwards. The first and second fixing rings are narrower at the top and wider at the bottom, resulting in a smaller opening at the top of the bag, facilitating material transport and increasing discharge efficiency. The addition of a first screw also facilitates the disassembly and installation of the fixed receiving mechanism. However, the aforementioned auxiliary material feeding pipe makes it inconvenient for operators to constantly observe the material flow and the internal condition of the pipe, hindering timely problem detection and resolution, thus reducing production efficiency. Furthermore, the auxiliary material feeding pipe is difficult to disassemble, making cleaning after use cumbersome.

[0004] To address this issue, we propose a dustproof feeding auxiliary pipe for the production of color masterbatch for PE pipes. Utility Model Content

[0005] The purpose of this utility model is to provide a dustproof feeding auxiliary pipe for the production of PE pipe masterbatch, so as to solve the problems mentioned in the background art.

[0024] 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.

[0025] Please see Figure 1-5This utility model provides a technical solution: a dustproof feeding auxiliary pipe for the production of PE pipe masterbatch, including a fixed pipe 1, a connection port 2 fixedly connected to the upper end of the fixed pipe 1, movable rods 3 inserted on the left and right sides and the front and rear ends of the fixed pipe 1, and the movable rods 3 are connected to the positioning plate 5 through the fixed sleeve 4, a first connecting pipe 6 fixedly connected to the lower end of the fixed pipe 1, and a second connecting pipe 8 connected to the first connecting pipe 6 through the sleeve 7, and a discharge port 10 connected to the lower end of the second connecting pipe 8 through the connecting sleeve 9.

[0026] The lower end of the fixed pipe 1 is designed as a conical structure. The inner dimension of the fixed pipe 1 is larger than the outer dimension of the connecting port 2. The lower end of the connecting port 2 is fixedly connected to the inside of the fixed pipe 1. The connecting port 2 and the fixed pipe 1 form a ring structure. The conical structure makes it easier for the material to slide downward under the action of gravity, reducing the accumulation and retention at the connection. This is especially important for powdery or granular materials in the production of PE pipe masterbatch. It can effectively prevent material blockage and ensure the continuity of production. Under the guidance of the conical structure, the material can enter the next production stage more evenly, improving the material conveying efficiency and production efficiency.

[0027] The outer surface of the moving rod 3 is evenly distributed with threads. The fixed tube 1 is equipped with a threaded sleeve that mates with the moving rod 3. One end of the moving rod 3 near the connection port 2 is movably engaged in the fixed sleeve 4 by an annular locking block. The fixed sleeve 4 has an annular groove that mates with the annular locking block. The positioning plate 5 is designed with an arc-shaped structure. A rubber pad is fixedly connected to the side of the positioning plate 5 near the connection port 2. By rotating the moving rod 3, the moving rod 3 moves the positioning plate 5 through the fixed sleeve 4, so that the other end of the positioning plate 5 abuts against the bag opening, thereby positioning the bag opening. The moving rod 3 is movably engaged with the annular groove on the fixed sleeve 4 by the annular locking block. This structure can enhance the connection stability between the moving rod 3 and the fixed sleeve 4. The annular locking block can rotate and slide freely in the annular groove, while also restricting the radial and axial displacement of the moving rod 3, so that the moving rod 3 is firmly positioned in the fixed sleeve 4. The rubber pad can form a soft isolation layer between the positioning plate 5 and the connection port 2, reducing scratches and wear, and reducing the maintenance cost of the equipment.

[0028] An observation window is provided on the outer surface of the first connecting pipe 6, and an observation window is provided on the right outer surface of the sleeve 7. In the production of PE pipe masterbatch, the flow status of the material inside the pipe can be observed in real time through the observation window. For example, the operator can directly see the conveying status of the masterbatch in the pipeline, including the flow rate, flow volume, and whether there is any blockage. This helps to detect abnormal material flow in a timely manner, such as material accumulation or unstable flow, so that corresponding measures can be taken to make adjustments and ensure the continuity and stability of production.

[0029] Both the first connecting pipe 6 and the second connecting pipe 8 are equipped with T-shaped locking blocks on their outer sides, and rubber locking balls are fixedly connected to both sides of the T-shaped locking blocks. The inner wall of the sleeve 7 has T-shaped slots that mate with the T-shaped locking blocks, and the inner wall of the T-shaped slots also has slots that mate with the rubber locking balls. The engagement of the T-shaped locking blocks and the T-shaped slots effectively restricts the circumferential rotation of the first connecting pipe 6 and the second connecting pipe 8 within the sleeve 7. In the production of PE pipe masterbatch, the material conveying direction needs to remain stable. When the first connecting pipe 6 and the second connecting pipe 8 are inserted into the sleeve 7, the T-shaped locking blocks will move along... The T-shaped slot moves accurately to the designated position. When the first connecting tube 6 is inserted into the sleeve 7, the rubber ball is squeezed into the slot, filling the gap between the first connecting tube 6 and the sleeve 7, thus providing a preliminary seal. When the equipment needs maintenance or replacement of parts, the structure of the T-shaped block and the rubber ball also facilitates the disassembly of the first connecting tube 6. The operator can apply a certain pulling force to smoothly remove the first connecting tube 6 from the sleeve 7. This easy-to-disassemble design helps to reduce the maintenance difficulty and cost of the equipment and facilitates the inspection, maintenance or replacement of internal components.

[0030] The upper part of the connecting sleeve 9 is designed with an arc shape, and the upper outer surface of the outlet 10 has evenly distributed threads. The upper thread of the outlet 10 is inserted into the connecting sleeve 9, and the lower end of the outlet 10 is designed with a conical structure. The arc shape of the upper part of the connecting sleeve 9 can guide the flow of materials. In the production process of PE pipe masterbatch, after the material enters the connecting sleeve 9 from above, the arc design allows the material to flow naturally along the arc, changing the direction of material movement and making it transition more smoothly to the outlet 10. This can avoid dead corners or accumulation of materials inside the connecting sleeve 9, ensuring continuous material conveying and reducing the risk of blockage caused by material accumulation. The fit between the thread at the upper end of the outlet 10 and the connecting sleeve 9 can provide good sealing performance. Preventing material leakage is very important in production, especially when dealing with some masterbatches that are environmentally polluting or costly. The threaded connection allows the outlet 10 to be tightly connected to the connecting sleeve 9, filling the gap between them and effectively preventing material leakage from the connection. The threaded connection makes the installation and disassembly of the outlet 10 and the connecting sleeve 9 very convenient. During the initial installation of the equipment, the operator can easily connect the outlet 10 to the connecting sleeve 9 by rotation and can adjust the tightness of the connection as needed. When the equipment is repaired or parts are replaced, the outlet 10 can be quickly removed from the connecting sleeve 9 without the need for complicated tools or extensive disassembly work.

[0031] Working principle: The bag opening to be connected is sleeved on the outside of the connecting port 2. By rotating the moving rod 3, the moving rod 3 drives the positioning plate 5 to move, so that the positioning plate 5 abuts against the outer surface of the bag opening, and the bag opening is positioned. Then, the first connecting pipe 6 and the second connecting pipe 8 are adjusted to the appropriate position, and the discharge port 10 is threaded into the connecting sleeve 9, so that the material can be discharged through the discharge port 10.

[0032] Finally, the following points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be interpreted broadly, and can be mechanical or electrical connections, or internal connections between two components, or direct connections.
