Description

Technical Field

[0001] This utility model belongs to the field of flame retardant processing, specifically relating to a pelletizer for processing halogen-free flame retardant granular materials. Background Technology

[0002] Halogen-free flame retardant granular materials refer to flame retardant materials that do not contain halogen components. Their main components are usually metal oxides and organic compounds. They do not release toxic gases when burning and have the characteristics of low smoke and non-toxicity. Therefore, halogen-free flame retardant granular materials are often added to the base material as flame retardants. The heat absorption, decomposition and dehydration of the halogen-free flame retardant granular materials are used to inhibit combustion, thereby ensuring the safety of the product during use.

[0003] There are many types of halogen-free flame retardant granules available now. When processing halogen-free flame retardant granules, a pelletizer is used to crush and pelletize the material, making it easier to incorporate the halogen-free flame retardant granules into polymer materials such as plastics.

[0004] When a pelletizer processes materials, it uses rotating blades inside the machine to cut the materials into pellets. However, during the pelletizing process, some materials cannot be fully processed by the blades, resulting in pellets that are larger than expected and affecting the overall processing quality.

[0023] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0024] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0025] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments. The present invention provides the following embodiments.

[0026] Depend on Figure 1 and Figure 2 As shown, this is a schematic diagram of the structure of the pelletizer for processing halogen-free flame-retardant granular materials in this embodiment. The pelletizer includes a pelletizer body 1, a control box 2, a pelletizing assembly 3, and a guide plate 4. The control box 2 is installed on the side of the pelletizer body 1, and the pelletizing assembly 3 is installed on the other side of the pelletizer body 1. The guide plate 4 is installed at the bottom opening of the pelletizing assembly 3. A screening mechanism 5 for screening and cutting the particle size is installed inside the guide plate 4.

[0027] The halogen-free flame-retardant granules to be pelletized are poured into the pelletizing assembly 3. Then, through the cooperation of the control box 2 and the pelletizing assembly 3, the input halogen-free flame-retardant granules are processed. The pelletized granules are directly output through the guide plate 4, thus completing the processing and pelletizing of the halogen-free flame-retardant granules.

[0028] From the appendix Figure 3 As shown, this is a schematic diagram of the screening mechanism 5 in this embodiment. The screening mechanism 5 includes a screening screen plate 51, a rotating end 52, a rotating chamber 53, and a driving assembly 54. The rotating chamber 53 is installed on one side of the inner wall of the guide plate 4, and the rotating end 52 is installed on the side of the rotating chamber 53. Rotating rods are installed at both ends of the rotating end 52, and the rotating rods are rotatably connected to the rotating chamber 53. A groove is provided on the inner wall of the guide plate 4 to cooperate with the screening screen plate 51 for rotation. The screening screen plate 51 for screening particles is installed at the end of the rotating end 52. The driving assembly 54 is installed inside the guide plate 4 and at the end of the screening screen plate 51. An output slot for screening particles is provided on the side wall of the guide plate 4 and at the end of the screening screen plate 51.

[0029] After the pelletizing assembly 3 finishes processing the input halogen-free flame-retardant pellet material, the pellets are output through the guide plate 4 and fall onto the surface of the screening screen 51. Particles that meet the specifications pass directly through the screening screen 51 and are discharged, while particles that do not meet the specifications accumulate on the upper surface of the screening screen 51. At this time, by using the drive assembly 54, the screening screen 51 is driven to shake on the inner wall of the guide plate 4, so that the screening screen 51 shakes up and down around the rotating rod as the axis, so that particles that do not meet the specifications are discharged directly from the side output slot, thus realizing the screening of the pelletized material.

[0030] From the appendix Figure 4 As shown, this is a schematic diagram of the drive assembly 54 in this embodiment. The drive assembly 54 includes a drive motor 541, a connecting rod 542, a cam assembly 543, and a bonding plate 544. The drive motor 541 is mounted on the side of the guide plate 4. The connecting rod 542 is mounted on the output end of the drive motor 541. The connecting rod 542 passes through the guide plate 4. The cam assembly 543 is mounted on the outside of the connecting rod 542. The bonding plate 544 is mounted on the bottom end of the screening screen plate 51 and at the top of the cam assembly 543. The cam assembly 543 and the bonding plate 544 are in contact by compression.

[0031] During use, the drive motor 541 drives the connecting rod 542 to rotate. At this time, the cam assembly 543 installed outside the connecting rod 542 rotates. Utilizing the structure and shape of the cam assembly 543 itself, the cam assembly 543 pushes the bonding plate 544 at the end of the screening screen plate 51, so that the overall angle of the screening screen plate 51 changes with the rotation of the cam assembly 543, thereby achieving vibration at one end of the screening screen plate 51 and realizing the purpose of directly discharging non-compliant particles accumulated on the surface of the screening screen plate 51.

[0032] From the appendix Figure 5 As shown, this is a structural schematic diagram of the sealing mechanism 6 in this embodiment. It also includes a sealing mechanism 6, which includes an input pipe 61, a compression cover 62, an electric cylinder 63, and a sealing cover 64. The top of the pelletizing assembly 3 is equipped with an input pipe 61, and the pelletizing assembly 3 is equipped with an electric cylinder 63. The output end of the electric cylinder 63 is equipped with a compression cover 62, and the bottom end of the compression cover 62 is equipped with a sealing cover 64. The overall radius of the sealing cover 64 is equal to the inner diameter of the input pipe 61.

[0033] After the halogen-free flame-retardant granules enter the pelletizing assembly 3 through the input pipe 61, the operation of the electric cylinder 63 drives the overall height of the extrusion cover 62 to change. This causes the sealing cover 64 at the bottom of the extrusion cover 62 to seal and block the opening at the top of the input pipe 61, thereby preventing some material from splashing out during the processing of the halogen-free flame-retardant granules inside the pelletizing assembly 3. Furthermore, some excess material is stably squeezed into the pelletizing assembly 3 by the extrusion cover 62, ensuring the stability of the pelletizing operation.

[0034] From the appendix Figure 2 As shown, a receiving bin is provided at the bottom opening of the guide plate 4, and a waste bin is provided on the side of the receiving bin to receive the particles screened out by the screening mechanism 5. In use, the receiving bin stably collects the particles that meet the specifications discharged from the guide plate 4, while the waste bin receives the waste discharged from the output slot, which is convenient for subsequent reprocessing of the waste.

[0035] The above description, in conjunction with specific embodiments, provides a further detailed explanation of the present utility model. It should not be construed that the specific implementation of the present utility model is limited to these descriptions. For those skilled in the art, several simple deductions or substitutions can be made without departing from the concept of the present utility model, and all such deductions or substitutions should be considered to fall within the scope of protection defined by the claims submitted by the present utility model.
