Description

Technical Field

[0001] This utility model relates to the field of polymer material processing technology, and in particular to an extrusion mold for uniformly dispersing and mixing antistatic agents. Background Technology

[0002] Antistatic agents are a class of functional additives that can reduce the surface resistance of materials and accelerate the leakage of static charge. In the field of polymer material processing, the application of antistatic agents is crucial. Since most polymer materials are insulators, they are prone to static electricity accumulation during processing or use due to friction, contact separation, and other effects. This can not only cause dust to be attracted to the products and affect their appearance, but may also cause safety hazards such as electric shock, fire, or even explosion. Therefore, adding antistatic agents to impart conductivity to materials has become an industry necessity.

[0003] However, the function of antistatic agents is highly dependent on their uniform dispersion with raw materials. If the antistatic agent is unevenly distributed in the material, it will cause fluctuations in the surface resistance of the material, and the stability and durability of the antistatic performance will be significantly reduced. In the prior art, the mixing of antistatic agents and raw materials usually relies on a single mechanical stirring or a single-layer conveying structure. However, a single mixing is difficult to disrupt the laminar flow state of the material, and the antistatic agent is prone to sedimentation or stratification under gravity or viscosity differences. Utility Model Content

[0004] To overcome the above deficiencies, this utility model provides an extrusion die for uniformly dispersing and mixing antistatic agents, aiming to improve the problem in the prior art where the mixing of antistatic agents and raw materials usually relies on a single mechanical stirring or a single-layer conveying structure, resulting in insufficient mixing of antistatic agents.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an antistatic agent uniform dispersion and mixing extrusion mold, including a first feeding pipe, a first feed pipe and a second feed pipe being fixedly connected through the inside of the first feeding pipe, a first baffle and a second baffle being fixedly connected to the inner wall of the first feeding pipe, an inclined discharge pipe being fixedly connected through the inside of the first baffle, a mixing fan blade being rotatably connected to the outer wall of the first baffle, a discharge port being opened inside the second baffle, and a mixing component being provided on the outer wall of the first feeding pipe.

[0006] Preferably, the mixing component includes a second feeding pipe, the outer wall of which is fixedly connected to the outer wall of the first feeding pipe, and a baffle is fixedly connected to the inner wall of the second feeding pipe.

[0007] Preferably, a support frame is fixedly connected to the outer wall of the first conveying pipe, and a filter screen is fixedly connected inside the support frame.

[0008] Preferably, the outer wall of the filter screen has a slot, and a connecting cylinder is fixedly connected inside the support frame.

[0009] Preferably, a limiting ring is fixedly connected to the inner wall of the connecting cylinder, and a locking block is slidably connected to the inner wall of the limiting ring.

[0010] Preferably, the outer wall of the card block is slidably connected to the outer wall of the filter screen, and the outer wall of the card block is slidably connected to the inner wall of the card slot.

[0011] Preferably, a spring is provided inside the connecting cylinder.

[0012] Preferably, one end of the spring is fixedly connected to the outer wall of the locking block, and the other end abuts against the inner wall of the connecting cylinder.

[0013] This utility model has the following beneficial effects:

[0014] 1. In this utility model, the antistatic agent and the raw material first enter the mixing zone between the first conveying pipe and the first baffle to be initially mixed to form a mixed liquid. Then the mixed liquid is discharged through the discharge pipe. At this time, the mixing fan blades will rotate under the impact of the mixed liquid, and the mixed liquid will be mixed again. Under the action of the baffle, the material can be mixed a third time in the second conveying pipe, thereby achieving the effect of fully mixing the antistatic agent and the raw material.

[0015] 2. In this utility model, by pulling the filter screen, the filter screen will squeeze the locking block and make it slide on the limiting ring. As the locking block slides, it will squeeze the spring and make it contract. When the locking block slides out of the slot, the filter screen can be taken out from the support frame. When installing the filter screen, simply insert the filter screen into the support frame. Under the spring's rebound, the locking block can then be abutted in the slot to fix the filter screen. Thus, by simply pulling the filter screen, it can be quickly installed or removed. Attached Figure Description

[0024] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0025] Reference Figure 1 , Figure 2 and Figure 3 An embodiment of this utility model provides an antistatic agent uniform dispersion and mixing extrusion mold, including a first feeding pipe 1, a first feed pipe 2 and a second feed pipe 3 that are fixedly connected through the inside of the first feeding pipe 1, a first baffle 4 and a second baffle 7 that are fixedly connected to the inner wall of the first feeding pipe 1, an inclined discharge pipe 5 that is fixedly connected through the inside of the first baffle 4, a mixing fan blade 6 that is rotatably connected to the outer wall of the first baffle 4, a discharge port that is opened inside the second baffle 7, and a mixing component that is provided on the outer wall of the first feeding pipe 1.

[0026] Specifically, the first feed pipe 2 is first connected to the antistatic agent tank, and the second feed pipe 3 is connected to the raw material tank. The antistatic agent and the raw material first enter the mixing zone between the first feed pipe 1 and the first baffle 4 for preliminary mixing to form a mixture. Then the mixture is discharged through the discharge pipe 5. At this time, the mixing fan blade 6 will rotate under the impact of the mixture. The mixture will be mixed again in the mixing zone between the first baffle 4 and the second baffle 7 in the first feed pipe 1, thereby further stirring the mixture and improving the mixing uniformity. The first feed pipe 1 is used to transport the antistatic agent and the raw material, thereby achieving the effect of transporting the two materials to the mixing zone. The first feed pipe 2 and the second feed pipe 3 are used to introduce the antistatic agent and the raw material into the first feed pipe 2, respectively.

[0027] Reference Figure 1 , Figure 2 and Figure 4 The mixing component includes a second feed pipe 8, the outer wall of which is fixedly connected to the outer wall of the first feed pipe 1, and a baffle 9 is fixedly connected to the inner wall of the second feed pipe 8.

[0028] Specifically, the material after being mixed again will be discharged into the second conveying pipe 8 through the second baffle 7. Under the action of the baffle 9, the material can be mixed a third time, so that the antistatic agent and the raw materials can be fully mixed. The second conveying pipe 8 serves to support and fix the baffle 9. Under the action of the baffle 9, the interior of the second conveying pipe 8 becomes a third mixing zone. The baffle 9 plays a role in obstructing and dispersing the flowing material, thereby achieving the effect of mixing the material a third time.

[0029] Reference Figure 1 , Figure 2 , Figure 5 and Figure 6 A support frame 10 is fixedly connected to the outer wall of the first feed pipe 1, and a filter screen 11 is fixedly connected inside the support frame 10. A slot 16 is opened on the outer wall of the filter screen 11, and a connecting cylinder 12 is fixedly connected inside the support frame 10. A limit ring 13 is fixedly connected to the inner wall of the connecting cylinder 12, and a locking block 14 is slidably connected to the inner wall of the limit ring 13. The outer wall of the locking block 14 is slidably connected to the outer wall of the filter screen 11, and the outer wall of the locking block 14 is slidably connected to the inner wall of the slot 16.

[0030] Specifically, when the filter 11 needs to be replaced, simply pull the filter 11. This causes the filter 11 to press against the locking block 14, making it slide on the limiting ring 13. The limiting ring 13 supports and limits the locking block 14, preventing it from sliding out of the connecting cylinder 12. Simultaneously, the sliding of the locking block 14 compresses the spring 15, causing it to contract. Once the locking block 14 slides out of the slot 16, the filter 11 can be removed from the support frame 10. When installing the filter 11, simply insert it into the support frame 10. The spring 15's rebound action further secures the locking block 14 against the slot 16. The function of the groove 16 is to fix the filter screen 11. When the antistatic agent and raw materials pass through the filter screen 11, the filter screen 11 also accelerates the mixing of the antistatic agent and raw materials. Under the filtration of the filter screen 11, large particles can be effectively blocked, thereby preventing the subsequent pipeline from being blocked and affecting the material extrusion. There are four sets of symmetrical slots 16 on both sides of the filter screen 11. Similarly, there are four sets of corresponding locking blocks 14 in the support frame 10. The connection between the filter screen 11 and the support frame 10 is provided with a sealing strip to prevent liquid leakage.

[0031] Reference Figure 1A spring 15 is installed inside the connecting cylinder 12; one end of the spring 15 is fixedly connected to the outer wall of the locking block 14, and the other end abuts against the inner wall of the connecting cylinder 12.

[0032] Specifically, the connecting cylinder 12 serves to support the limiting spring 15, thereby ensuring the stability of the spring 15 when it is compressed and contracted. The spring 15 provides elastic force to the locking block 14, thereby ensuring that the locking block 14 can be firmly locked in the locking groove 16.

[0033] Working principle: When the mold is needed, the first feed pipe 2 is connected to the antistatic agent hopper, and the second feed pipe 3 is connected to the raw material hopper. The antistatic agent and raw material first enter the mixing zone between the first feed pipe 1 and the first baffle 4 for preliminary mixing to form a mixture. Then the mixture is discharged through the discharge pipe 5. At this time, the mixing fan blade 6 will rotate under the impact of the mixture. The mixture will then be mixed again in the mixing zone between the first baffle 4 and the second baffle 7 in the first feed pipe 1. The material after being mixed again will be discharged into the second feed pipe 8 through the second baffle 7. Under the action of the baffle 9, the material can be mixed a third time, so that the antistatic agent and raw material can be fully mixed. When the antistatic agent and raw material pass through the filter screen 11, the filter screen 11 also plays a role in accelerating the mixing of the antistatic agent and raw material. Under the filtration of the filter screen 11, large particles can be effectively blocked, thus preventing the subsequent pipe from being blocked and affecting the material extrusion.

[0034] When the filter 11 needs to be replaced, simply pull the filter 11. At this time, the filter 11 will squeeze the locking block 14, causing it to slide on the limiting ring 13. As the locking block 14 slides, it will squeeze the spring 15, causing it to retract. After the locking block 14 slides out of the slot 16, the filter 11 can be taken out of the support frame 10. When installing the filter 11, simply insert the filter 11 into the support frame 10. Under the rebound of the spring 15, the locking block 14 can be pressed against the slot 16, thus fixing the filter 11.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
