Description

Technical Field

[0001] This utility model relates to the field of plastic granule processing technology, and specifically to a plastic granule anti-sticking device. Background Technology

[0002] Plastic granules are a commonly used basic raw material in the production of plastic products, widely used in molding processes such as injection molding, extrusion, and blow molding. They are typically obtained by heating and melting plastic raw materials, extruding them into strips, and then cutting them into granules. The granule morphology and quality directly affect the stability of subsequent processing and the performance of the finished product. In actual production, plastic granules need to possess good dimensional uniformity and flowability to facilitate storage, transportation, and automated feeding. Furthermore, the production process of plastic granules is often a continuous operation, placing high demands on the stability of equipment operation and the consistency of granule formation.

[0003] In current plastic pellet production processes, the molten plastic often remains at a relatively high temperature after pelleting, and the pellet surface has a certain degree of stickiness. The pellets typically fall directly and accumulate in the collection or conveying area, easily coming into contact with each other and sticking together during the fall and accumulation process, forming clumps. These problems not only affect the appearance and dispersibility of the plastic pellets but can also cause poor discharge, reduce production continuity, and adversely affect subsequent processing and use.

[0004] Therefore, it is necessary to provide a device that can effectively reduce the adhesion of plastic particles. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model proposes a plastic granule anti-agglomeration device to solve the problem that in the existing plastic granule production process, the plastic melt is often still at a high temperature after being granulated, and the surface of the granules has a certain degree of stickiness. The granulated plastic granules usually fall directly and concentrate in the collection or conveying area, which easily leads to contact and adhesion between each other during the falling and accumulation process, forming clumps.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A plastic pellet anti-sticking device, disposed at the discharge end of a plastic pellet cutting device, includes:

[0008] Cavity, guide section, and dispersion section;

[0009] The upper end of the cavity is provided with a feed inlet that communicates with the discharge end of the pelletizing device, and the lower end of the cavity is provided with a discharge outlet;

[0010] The flow guide is located below the feed inlet;

[0011] The dispersion section is located below the flow guide section.

[0012] Optionally, the guide portion includes a first guide fluid and a second guide fluid. The first guide fluid is disposed below the feed inlet and located in the middle of the cavity. The outer surface of the first guide fluid has a slope to guide the material to the surrounding area. The second guide fluid is wider at the top and narrower at the bottom, and passes through the middle and is located below the first guide fluid.

[0013] Optionally, the first fluid guide is a cone, the second fluid guide is a hollow frustum, the outer surface of the cone is circumferentially arranged with a plurality of first collision bodies, and the inner surface of the hollow frustum is circumferentially arranged with a plurality of second collision bodies.

[0014] Optionally, the dispersing section includes a plurality of dispersing strips, which are arranged alternately within the cavity, and each of the dispersing strips has an edge on its upper side.

[0015] Optionally, the dispersion section is provided with multiple layers along the axial direction of the cavity, and the dispersion strips in each layer are arranged at uniform intervals along the cross-section of the cavity, with an included angle between the arrangement directions of the dispersion strips in each layer.

[0016] Optionally, each of the dispersion impact bars is rotatably disposed in the cavity via a rotating shaft, and each of the dispersion impact bars has a limiting part at one end. The limiting part is fork-shaped and clamps the dispersion impact bar in the middle to limit the swing angle of the dispersion impact bar.

[0017] As can be seen from the above technical solution, the beneficial technical effects of this utility model are as follows:

[0018] 1. This device incorporates a cavity at the discharge end of the plastic pelletizing unit, within which a guide section and a dispersion section are sequentially arranged. This allows the granulated plastic pellets to undergo a guiding and dispersion process before entering the collection area. The cavity provides a stable falling space for the pellets, the guide section adjusts the initial falling path of the pellets, and the dispersion section continuously separates the pellets. Structurally, this reduces the phenomenon of pellet aggregation, effectively lowering the risk of adhesion of high-temperature plastic pellets during the falling and collection process, and improving overall production stability.

[0019] 2. In terms of specific structure, the combination of the first and second guide fluids enables multi-stage flow guidance for the plastic particles. Combined with the cone, the hollow frustum, and the collision bodies on their surfaces, the direction of particle movement is intervened multiple times. At the same time, the dispersion section adopts a multi-layered, staggered, and swingable dispersion impact bar structure, which allows the particles to continuously change their direction of movement and maintain a dispersed state during the falling process, thereby further enhancing the anti-adhesion effect and improving the molding quality of plastic particles.

[0025] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0026] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application shall have the ordinary meaning as understood by one of ordinary skill in the art to which this utility model pertains.

[0027] like Figures 1-3 The device shown is a plastic granule anti-sticking device, which is installed at the discharge end of the plastic granule cutting device and includes: a cavity 1, a guide section and a dispersion section; the upper end of the cavity 1 is provided with a feed inlet 11 that communicates with the discharge end of the cutting device, and the lower end of the cavity 1 is provided with a discharge outlet; the guide section is located below the feed inlet 11; and the dispersion section is located below the guide section.

[0028] This device, by incorporating a cavity 1, a guide section, and a dispersion section at the discharge end of the plastic pelletizing unit, ensures that the granulated plastic pellets undergo a guiding and dispersion process sequentially before entering the collection area, structurally reducing the concentrated accumulation of pellets. The guide section, located below the feed inlet 11, adjusts the movement path of the plastic pellets during the initial descent stage, preventing pellets from directly impacting the central area of ​​the cavity 1, thereby reducing the risk of localized accumulation and adhesion. The dispersion section, located below the guide section, further disperses and diverts the plastic pellets as they continue to fall, extending the separation time between pellets and reducing the chance of pellets contacting each other at high temperatures. Through the synergistic effect of these structures, the dispersion state of the granulated plastic pellets can be effectively improved without adding complex control structures, reducing the probability of adhesion and enhancing the stability of the plastic pellet production process and the quality of the finished product.

[0029] In alternative implementations, such as Figure 2 As shown, the guide section includes a first guide fluid 2 and a second guide fluid 3. The first guide fluid 2 is located below the feed inlet 11 and in the middle of the cavity 1. The outer surface of the first guide fluid 2 has a slope to guide the material to the surrounding area. The second guide fluid 3 is wider at the top and narrower at the bottom, and has a through-hole in the middle and is located below the first guide fluid 2.

[0030] The guiding section includes a first guiding fluid 2 and a second guiding fluid 3, enabling the plastic particles to transition from concentrated to dispersed flow after entering the cavity 1. The first guiding fluid 2 is located below the feed inlet 11 and in the middle of the cavity 1. Its outer surface has a slope that guides the plastic particles falling from the feed inlet 11 to the surrounding areas of the cavity 1, preventing particles from concentrating and impacting the same location, thus reducing initial accumulation. The second guiding fluid 3 is located below the first guiding fluid 2 and has a structure that is wider at the top and narrower at the bottom with a through-flow in the middle. This allows the plastic particles, after being diverted by the first guiding fluid 2, to be guided again and redistributed evenly, further widening the particle spacing as they pass through the second guiding fluid 3. Through the cooperation of the first guiding fluid 2 and the second guiding fluid 3, graded guidance of the plastic particles can be achieved, making the particle falling path more dispersed and reducing the tendency for high-temperature particles to stick together.

[0031] Specifically, such as Figure 2 As shown, the first guide fluid 2 is a cone, the second guide fluid 3 is a hollow frustum, a plurality of first collision bodies 21 are arranged circumferentially on the outer surface of the cone, and a plurality of second collision bodies 31 are arranged circumferentially on the inner surface of the hollow frustum.

[0032] When the first guide tube 2 adopts a conical structure and the second guide tube 3 adopts a hollow frustum structure, the guiding and dispersing effect of plastic particles can be further optimized. The outer surface of the cone has a continuously inclined structure, allowing the plastic particles to slide along its outer surface in all directions after falling and contacting the cone, thereby achieving uniform flow distribution. Generally, the cone can be installed in the cavity 1 using conventional means such as support rods or support frames. The hollow frustum has a structure that is wider at the top and narrower at the bottom and open in the middle, allowing the plastic particles to gradually converge and redistribute as they pass through its internal space, which helps to lengthen the falling path of the particles. Generally, the lower side of the hollow frustum does not need to be very narrow to avoid the plastic particles colliding and sticking together. Multiple first collision bodies 21 or second collision bodies 31 are provided on both the outer surface of the cone and the inner surface of the hollow frustum, so that the plastic particles will slightly collide with the collision bodies during the guiding process, thereby further dispersing the particle group. The first collision bodies 21 and second collision bodies 31 can be strip-shaped or dot-shaped, and can be evenly arranged to enhance the guiding and dispersing effect. When the collision bodies are strip-shaped, they are generally evenly arranged vertically.

[0033] In yet another implementation, such as Figure 2 As shown, the dispersion section includes multiple dispersion impact bars 4, which are arranged alternately inside the cavity 1, and each dispersion impact bar 4 has an edge on its upper side.

[0034] The dispersion section includes multiple dispersion impact bars 4, which are staggered within the cavity 1. This staggering can be formed at circumferential or pitch angles, preventing the plastic particles from forming a continuous linear motion path during their descent. Each dispersion impact bar 4 has an angular structure on its upper side. When a plastic particle comes into contact with the dispersion impact bar 4, the angular structure can disturb and impact the particle, changing its direction of motion or breaking up particles that are stuck together. The staggered dispersion impact bars 4 can intervene in the plastic particles multiple times at different heights and positions, prolonging the separation time between particles, reducing the possibility of particles contacting and sticking together at high temperatures, and thus improving the particle dispersion effect.

[0035] Optionally, such as Figure 2 As shown, the dispersion section is provided with multiple layers along the axial direction of the cavity 1. Each layer of dispersion strips 4 is arranged at uniform intervals along the cross-section of the cavity 1, and there is an angle between the arrangement directions of each layer of dispersion strips 4.

[0036] When multiple layers of dispersing strips 4 are arranged along the axial direction of the cavity 1, and each layer of dispersing strips 4 is evenly spaced along the cross-section of the cavity 1, with an angle between the arrangement directions of adjacent layers of dispersing strips 4, the plastic particles can be dispersed in multiple directions during their fall. The directional differences between different layers of dispersing strips 4 cause the particles to continuously change their direction of movement as they pass through each layer, preventing the particles from falling continuously in the same direction and re-aggregating. This structure can form a multi-level, uniform, and three-dimensional dispersion path, further enhancing the separation effect of the plastic particles and reducing the probability of agglomeration. In some possible cases, the dispersing strips 4 can also be evenly distributed along the oblique section of the cavity 1, and the angle between the arrangement directions of each layer can be set as needed, such as 30 degrees, 60 degrees, etc.

[0037] In a further optimized implementation, such as Figure 3 As shown, each dispersion impact bar 4 is rotatably mounted in the cavity 1 via a rotating shaft 5. Each dispersion impact bar 4 has a limiting part 6 at one end. The limiting part 6 is forked and clamps the dispersion impact bar 4 in the middle to limit the swing angle of the dispersion impact bar 4.

[0038] Each dispersing impact bar 4 is rotatably mounted inside the cavity 1 via a rotating shaft 5, allowing the dispersing impact bar 4 to oscillate to a certain amplitude under the impact of plastic particles, thereby creating dynamic disturbance to the particles and enhancing the dispersion effect. The limiting part 6 at one end of the dispersing impact bar 4 has a fork-shaped structure, which clamps the dispersing impact bar 4 in the middle to limit its oscillation angle, which can prevent the dispersing impact bar 4 from rotating excessively and ensure that the dispersing impact bar 4 oscillates within a reasonable range.

[0039] The working process of this embodiment is as follows:

[0040] like Figures 1-3 As shown, during operation, plastic granules are cut by the pelletizing device and enter the device through the feed inlet 11 of the cavity 1. Under gravity, the granules fall to the guide section. Under the slope of the first guide section 2, the plastic granules disperse from the center of the cavity 1 to the surrounding areas, preventing concentrated falling. The granules then continue to fall and enter the second guide section 3 below. Through its structure (wider at the top, narrower at the bottom, and open in the middle), the falling path of the plastic granules is further adjusted and redistributed. During the guide process, the plastic granules come into contact multiple times with the collision bodies on the outer surface of the cone and the inner surface of the truncated cone, thereby changing their direction of motion and increasing the spacing between the granules. After being guided, the plastic granules enter the dispersion section, where they continuously collide and deflect under the action of multiple dispersion impact bars 4. Guided by the multi-layered, differently arranged dispersion impact bars 4, the plastic granules are continuously dispersed and kept in a separated state, finally being evenly discharged from the outlet at the lower end of the cavity 1, thus effectively reducing particle adhesion.
