Abstract
Description
Technical Field
[0001] The utility model relates to the field of plastic particles, in particular to a kind of plastic modified particles. Background Art
[0002] Modified particles refer to plastic particles prepared by cutting and granulating thermoplastics. Because these particles have thermoplastic properties, they can be heated to a molten state, injected into a mold, and then cooled to obtain the desired products. During the process, the particles can be mixed with different types of modifiers (such as anti-ultraviolet, anti-yellowing, etc.) to give the products different functions.
[0003] The modifier is generally in powder form and has a large difference in particle size between the modified particles. During the mixing and heating process, the mixture is prone to accumulate in large quantities at the bottom of the mixture due to the difference in particle size. The poor binding between the particles and the modifier requires a poor mixing time and heating time. The purpose of the utility model is to improve the structure of the modified particles to improve the binding between the modified particles and the modifier and shorten the time required for mixing and heating. Utility Model Content
[0004] The purpose of the utility model is to provide a plastic modified 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 scheme: including a particle body, an upper side plate, a lower side plate and a cutout, the particle body is tubular so that the front and rear ends of the particle body are connected to the outside, the upper side plates are respectively located on both sides of the particle body and connected to the particle body, the upper side plates are bent toward the top of the particle body, the lower side plates are respectively located on both sides of the particle body and connected to the particle body, the lower side plates are bent toward the bottom of the particle body, the cutout is located on the upper side plate, and the cutout is perpendicular to the length direction of the particle body.
[0006] In order to optimize the above technical solution, further measures are taken as follows: a notch is formed at the bottom of the particle body, and the notch is distributed along the length direction of the particle body so that the cross-section of the particle body is C-shaped. The notch can improve the connectivity of the particle body with the outside through the outside, which helps to increase the contact area between the particle body and the hot air and thermal radiation, thereby improving the heating effect of the particle body. At the same time, setting the notch can improve the deformation ability of the particle body.
[0007] As a further improvement of the present invention, the depth of the cut does not exceed the distance from the top of the upper side plate to the notch, and a cutting margin is reserved to prevent the notch from being too deep, causing the particle body to break and the particle size of the particle body to be too small.
[0008] Preferably, the thickness of the upper side plate gradually decreases from the bottom end of the upper side plate to the top end of the upper side plate, and the deformation capacity of the top of the upper side plate can be improved by regularly reducing the thickness.
[0009] Preferably, along the direction from the top end to the bottom end of the lower side plate, the thickness of the lower side plate gradually decreases. The regular decrease in thickness can improve the deformation ability of the bottom of the lower side plate.
[0010] From the above description of the structure of the present invention, compared with the prior art, the present invention has the following advantages:
[0011] A kind of plastic modified particle provided by the present invention is transformed into a hollow structure conducive to the passage of hot air, which helps the hot air to flow inside the modified particle, helps to shorten the heating time of the modified particle, promotes the plastic particle to quickly enter the molten state and combine with the modified powder, and avoids the layering of the powder and the particle. In addition, the notch and the incision improve the deformation ability of the modified particle, and can quickly deform and wrap the modified separation under the external action during the heating and mixing processes, improving the combination of the particle and the modified powder.

[0017] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0018] Embodiment
[0019] Please refer to Figures 1-3, the present utility model provides a plastic modified particle, including a particle main body 1, upper side plates 2, lower side plates 3 and incisions 4. The particle main body 1 is tubular so that the front and rear ends of the particle main body 1 communicate with the outside. A notch 101 is formed at the bottom of the particle main body 1, and the notch 101 is distributed along the length direction of the particle main body 1 so that the cross section of the particle main body 1 is C-shaped.
[0020] The upper side plates 2 are respectively located on both sides of the particle main body 1 and connected to the particle main body 1. The upper side plates 2 are bent towards the top of the particle main body 1, and along the direction from the bottom end to the top end of the upper side plates 2, the thickness of the upper side plates 2 gradually decreases.
[0021] The lower side plates 3 are respectively located on both sides of the particle main body 1 and connected to the particle main body 1. The lower side plates 3 are bent towards the bottom of the particle main body 1, and along the direction from the top end to the bottom end of the lower side plates 3, the thickness of the lower side plates 3 gradually decreases.
[0022] The incision 4 is located on the upper side plate 2. The incision 4 is perpendicular to the length direction of the particle main body 1, and the depth of the incision 4 does not exceed the distance from the top end of the upper side plate 2 to the notch 101. The incision 4 can be formed by cutting with a cutter. By changing the downward distance of the cutter in the cutting and granulation section, the incision 4 can be cut on the plastic strip.
[0023] The application purpose of the present utility model is to protect the structure. The specific material is not the technical content to be protected by the applicant, so it will not be further explained. In the specific implementation, by changing the shape of the extrusion die of the plastic strip, the modified particles can be made into the required shape. This description is clear enough for those skilled in the art to understand and will not cause the problem of ambiguity in the technical solution.
[0024] Working principle: A tubular particle main body 1 with a notch 101 is formed on the modified particle. In addition, there is a space between the upper side plates 2 and the lower side plates 3 at both ends of the particle main body 1 and the particle main body 1 for hot air to pass through. The notch 101, the particle main body 1, the upper side plates 2 and the lower side plates 3 cooperate with each other to make the modified particle in a hollow shape, which helps the modified particle to be quickly heated by hot air, improves the heating and melting efficiency of the modified particle, and helps the modified particle to be quickly mixed with various modified powders. In addition, the incision 4 on the upper side plate 2 can also supply hot air to flow, which can play the role of promoting the melting of the modified particle.
[0025] The notch 101 provided on the particle main body 1 helps the lower side plate 3 to generate deformation, and the incision 4 opened on the upper side plate 2 helps the upper side plate 2 to generate deformation along the incision 4. During the mixing and heating process, after the modified particle is affected by external forces, it is easy to generate deformation at the upper side plate 2 and the incision 4 to wrap the modified powder, improving the binding property between the modified particle and the modified powder and reducing the time required for material mixing.
[0026] 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 perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
