Description

Technical Field

[0001] The utility model relates to the field of plastic particles, in particular to recycled plastic particles. Background Art

[0002] Thermoplastic plastics are thermoplastic. After being recycled and melted, they are extruded from the die. After cooling and hardening, they are cut and granulated to form recycled plastic particles. When in use, the plastic particles are mixed with fillers (such as plasticizers, tougheners, UV resistance, and yellowing resistance), heated to a uniform molten state, injected into the mold, and waited for cooling to obtain the corresponding products.

[0003] The heating of plastic particles mainly relies on heat conduction and requires a certain heating time. Secondly, during the heating process, the filler is easily separated from the plastic particles and accumulated at the bottom of the mixture. Therefore, the mixture still needs to be stirred after it is melted (the application number is 202222107446.7, a flux-type PET recycled plastic rice particle, and the corresponding technical problems are also mentioned in the background technology). The purpose of the utility model is to propose a structure of plastic particles to shorten the time required for heating to reduce the separation of fillers. Utility Model Content

[0004] The purpose of the utility model is to provide a recycled plastic particle to solve the problems mentioned in the background technology.

[0005] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: including a particle body, a heat-conducting seam and a deformation seam, a heat-conducting groove is formed in the axial direction of the particle body, the heat-conducting groove runs through the front and rear ends of the particle body, the heat-conducting seam is located at the bottom of the particle body and distributed along the length direction of the particle body, the two ends of the heat-conducting seam are respectively connected to the outside and the heat-conducting groove, and the deformation seam is respectively located at the top of the particle body and the left and right sides of the particle body.

[0006] In order to optimize the above technical solution, further measures are taken: the cross-section shapes of the front and rear ends of the particle body are irregular. The irregular cross-section reduces the stacking of the particle body on the cross-section, which helps to expand the gap between the particles and shorten the particles.

[0007] As a further improvement to the above technical solution: the cross-sections at the front and rear ends of the particle body are W-shaped, and the cross-sectional area of ​​the particle body becomes smaller as the W-shaped cross-section gets closer to the end, which helps the particle body to produce irregular deformation at both ends, helps to produce gaps between particles, promotes the flow of hot air between plastic particles, and shortens the heating time.

[0008] As a further improvement of the technical solution: the cross-section of the deformation joint is narrow at the top and wide at the bottom, which helps the particle body to deform on both sides of the deformation joint, and can destroy the regularity between the plastic particles to form gaps for hot air to pass through.

[0009] As an improvement to the above technical solution: the cross-section of the heat-conducting seam is narrow at the top and wide at the bottom, which helps the particle body to deform on both sides of the heat-conducting seam, destroys the regularity between the plastic particles and forms gaps for hot air to pass through.

[0010] From the above description of the structure of the utility model, it can be seen that compared with the prior art, the utility model has the following advantages:

[0011] The utility model provides a recycled plastic particle, which improves the hollowing degree of the particle by arranging heat-conducting grooves, heat-conducting seams and deformation seams, so that there are gaps for heating air to pass through in a stacked state, which helps to shorten the time for the plastic particles to be heated by hot air. Secondly, the arrangement of the deformation seams makes it easy for the plastic particles to produce irregular deformations, and destroying the regularity of the plastic particles is conducive to the formation of gaps for heating air to pass through.

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] Example

[0019] See also Figure 1-3 The utility model provides a recycled plastic particle, including a particle body 1, a heat-conducting seam 2 and a deformation seam 3. The cross-section of the front and rear ends of the particle body 1 is W-shaped, and a heat-conducting groove 101 is formed in the axial direction of the particle body 1. The heat-conducting groove 101 runs through the front and rear ends of the particle body 1.

[0020] The heat-conducting seam 2 is located at the bottom of the particle body 1 and distributed along the length direction of the particle body 1 , and two ends of the heat-conducting seam 2 are respectively connected to the outside and the heat-conducting groove 101 .

[0021] The deformation seams 3 are respectively located at the top of the particle body 1 and the left and right sides of the particle body 1 . The cross-sections of the deformation seams 3 and the heat-conducting seams 2 are narrow at the top and wide at the bottom.

[0022] The purpose of the utility model is to protect the structure of plastic particles. The specific material of the plastic particles is not what the applicant wants to protect, so no further explanation of its specific composition and material will be given, which will not constitute a problem of insufficient disclosure and will not have a substantial impact on the technical solution. The structure of the plastic particles can be obtained by changing the shape of the extrusion die to obtain the shape of the plastic particles in the technical solution, and the cross-sectional shape of the plastic particles can be achieved by cutting plastic strips with a W-shaped cutter.

[0023] Working principle: The granular body is formed with heat-conducting grooves 101, heat-conducting seams 2 and deformation seams 3, which increase the contact area between the plastic particles and the hot air, help the plastic particles to be heated by the hot air, and help shorten the heating time of the plastic particles. When the plastic particles are stacked, the heat-conducting seams 2 and deformation seams 3 can provide gaps for the flow of hot air, avoiding the close stacking of plastic particles, which makes it difficult for hot air to pass through the gaps between the particles.

[0024] The width of the particle body 1 at the deformation joint 3 is small, so when the particle body 1 is squeezed or subjected to external force during the mixing process, it is easy to deform at the deformation joint 3, causing the particle body 1 to deform. Since the deformation degree of each particle body 1 is inconsistent, there may be gaps between the plastic particles for hot air to pass through, which helps the hot air to heat the plastic particles through the gaps.

[0025] The cross sections at both ends of the particle body 1 are W-shaped rather than traditional flat cross sections. This setting is intended to prevent the particle body 1 from being stacked along the flat cross sections. The W-shaped cross sections make it difficult for the particle body to be stacked along the cross sections.

[0026] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
