Description

Technical Field

[0001] This utility model relates to the field of compound feeding technology, specifically a feeding mechanism for a polymer compound mixing equipment. Background Technology

[0002] The authorization announcement number CN219705733U discloses a feeding mechanism for a polymer compound mixing equipment, which includes a feeding pipe installed on the main body of an internal mixer. The feeding pipe includes a round pipe and a funnel. The round pipe is connected to the inside of the internal mixer body, and the funnel is used to temporarily store the compound. The round pipe and the internal mixer body have an angle, which is the feeding position, to facilitate the sliding of the compound. A feeding hopper is installed on the feeding pipe and is detachably connected to the feeding pipe. The feeding hopper is used to transport the compound. The proportioned compound is placed in the feeding hopper, and the feeding hopper is fastened to the feeding pipe so that the compound enters the inside of the internal mixer body through the feeding pipe.

[0003] Its feeding mechanism achieves the effect of auxiliary feeding.

[0004] However, raw materials are prone to clumping during storage and transportation due to moisture, static electricity, and other reasons. Directly adding clumped raw materials into the mixing drum will cause a series of problems: First, the clumped material is difficult to break up quickly, prolonging the mixing time and increasing energy consumption; second, undispersed particles may cause "fish-eye" defects or uneven performance in the final product, affecting product quality. This solution is not effective for treating clumped raw materials that are prone to uneven mixing. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides a feeding mechanism for a polymer compound mixing equipment, solving the problem that raw materials are prone to clumping due to moisture, static electricity, etc., during storage and transportation. Directly feeding clumped raw materials into the mixing drum leads to a series of problems: firstly, the clumped material is difficult to break up quickly, prolonging mixing time and increasing energy consumption; secondly, undispersed particles may cause "fish-eye" defects or uneven performance in the final product, affecting product quality.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a feeding mechanism for a polymer compound mixing equipment, comprising a mixing drum, a sealing cover being provided at the top of the mixing drum, a servo motor being fixedly installed in the middle of the surface of the sealing cover, a stirring rod being fixedly installed at the output end of the servo motor, an installation groove being provided on one side of the surface of the mixing drum, an installation frame being fixedly installed inside the installation groove, a filter assembly being provided inside the installation frame, a limit cover being fixedly installed at the top of the installation frame, and a feed inlet being fixedly installed in the middle of the surface of the limit cover;

[0007] The filter assembly includes a guide plate fixedly installed inside the mounting frame. Support rods are fixedly installed at the four corners of the guide plate surface. A filter plate is fixedly installed on the top of the support rods. Support plates are fixedly installed on both sides of the filter plate surface. A grinding cylinder is rotatably connected between the support plates. A drive motor is fixedly installed on one side of the support plate surface.

[0008] In one specific embodiment, a protective cover is fixedly installed on one side of the mounting frame surface, and a drive motor is provided inside the protective cover.

[0009] In one specific embodiment, there is a gap between the grinding cylinder and the filter plate, the size of which can be determined by powder.

[0010] In one specific embodiment, a guide groove is provided on the other side of the surface of the mounting frame, and the guide groove is located on one side inside the stirring cylinder.

[0011] In one specific embodiment, connecting plates are fixedly installed at the four corners of the limiting cover surface, and the bottom of the connecting plates is installed on the top of the mounting frame.

[0012] In one specific embodiment, the surface of the feed inlet is provided with a groove, and the interior of the groove is provided with a scale for observation.

[0013] Compared with the prior art, this utility model provides a feeding mechanism for a polymer compound mixing equipment, which has the following advantages:

[0014] The technical solution disclosed in this utility model utilizes a filtration assembly consisting of a filter plate and a grinding cylinder installed along the feeding path to achieve online pretreatment of the input raw materials. When agglomerated raw materials fall into the feed inlet, they will be blocked and continue to be ground until they pass through. This process ensures that the raw materials entering the mixing cylinder are fine and uniform, improving the quality of the compound from the source.

[0015] With the combined use of the feed inlet, mounting frame, and filter assembly provided by this utility model, during use, personnel introduce materials into the interior of the mounting frame through the feed inlet. Subsequently, the powdery material will fall downwards through the filter plate onto the surface of the guide plate. The support rod creates a gap between the filter plate and the support plate, and the powdery material falling onto the surface of the guide plate will then enter the interior of the mixing drum. The lumpy material will be ground by the grinding drum. After the lumpy material is ground into powder, it will enter the interior of the mixing drum through the gap between the filter plate and the grinding drum. This reduces the occurrence of lumpy material entering the mixing drum and being difficult to disperse quickly, thus reducing the occurrence of prolonged mixing time and increased energy consumption.

[0022] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0023] Figures 1-4 In one embodiment of this utility model, a feeding mechanism for a polymer compound mixing equipment includes a mixing drum 1, a sealing cover 2 on the top of the mixing drum 1, a servo motor 3 fixedly installed in the middle of the surface of the sealing cover 2, a stirring rod 4 fixedly installed at the output end of the servo motor 3, an installation groove is opened on one side of the surface of the mixing drum 1, an installation frame 5 is fixedly installed inside the installation groove, a filter assembly 6 is provided inside the installation frame 5, a limit cover 7 is fixedly installed on the top of the installation frame 5, and a feed inlet 8 is fixedly installed in the middle of the surface of the limit cover 7.

[0024] The specific problem addressed in this embodiment is the tendency of raw materials to clump during storage and transportation due to moisture, static electricity, etc. Directly adding clumped raw materials to the mixing drum 1 presents several issues: firstly, the clumps are difficult to break up quickly, prolonging mixing time and increasing energy consumption; secondly, undispersed particles may result in "fish-eye" defects or uneven performance in the final product, affecting product quality. This invention utilizes a filter assembly 6, consisting of a filter plate 63 and a grinding drum 65, along the feeding path to achieve online pretreatment of the input raw materials. When clumped raw materials fall into the feed inlet, they are blocked and continue to be ground until they pass through. This process ensures that the raw materials entering the mixing drum 1 are fine and uniform, improving the quality of the compound from the source.

[0025] The filter assembly 6 includes a guide plate 61 fixedly installed inside the mounting frame 5. Support rods 62 are fixedly installed at the four corners of the guide plate 61. A filter plate 63 is fixedly installed on the top of each support rod 62. Support plates 64 are fixedly installed on both sides of the filter plate 63. A grinding cylinder 65 is rotatably connected between the support plates 64. A drive motor 66 is fixedly installed on one side of the support plate 64. A protective cover 9 is fixedly installed on one side of the mounting frame 5. The drive motor 66 is located inside the protective cover 9. There is a gap between the grinding cylinder 65 and the filter plate 63, the size of which allows powder to pass through. In this specific embodiment, the feed inlet 8, the mounting frame 5, and the filter assembly 6 are... In conjunction with the above, during use, personnel introduce materials into the installation frame 5 through the feed inlet 8. Subsequently, the powdery material will fall down through the filter plate 63 onto the surface of the guide plate 61. The support rod 62 creates a gap between the filter plate 63 and the support plate 64. The powdery material falling onto the surface of the guide plate 61 will then enter the interior of the mixing drum 1. The lumpy material will be ground by the grinding drum 65. After the lumpy material is ground into powder, it will enter the interior of the mixing drum 1 through the gap between the filter plate 63 and the grinding drum 65. This reduces the likelihood of lumpy material entering the mixing drum 1 and being difficult to disperse quickly, thus reducing the occurrence of prolonged mixing time and increased energy consumption.

[0026] In this specific embodiment, a guide groove is provided on the other side of the surface of the mounting frame 5. The guide groove is located on one side inside the mixing drum 1. Connecting plates are fixedly installed at the four corners of the surface of the limiting cover 7. The bottom of the connecting plate is installed on the top of the mounting frame 5. A groove is provided on the surface of the feed port 8. The groove is provided with a scale for observation.

The power supply is also common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail.
