[0024] The embodiments of the present application will be described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference signs represent the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by reference to the accompanying drawings are exemplary and are intended to explain the present application, and cannot be understood as limiting the present application. On the contrary, the embodiments of the present application include all changes, modifications and equivalents falling within the spirit and scope of the appended claims.

[0025] The plastic particle granulator of the embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0026] As Figures 1-4 shown, the plastic particle granulator of the embodiment of the utility model can include a granulator body 1, an ejection housing 2, a support table 3, a collection bin 4, an agitation assembly 5 and a water cooling mechanism 6.

[0027] The ejection housing 2 is fixedly connected at one end in an inclined manner at the discharge port of the granulator body 1, the support table 3 is fixedly connected at the bottom on one side of the granulator body 1, the collection bin 4 is fixedly connected at the top of the support table 3, and the agitation assembly 5 is installed at the top of the ejection housing 2.

[0028] It should be noted that the inclined arrangement of the ejection housing 2 described in this embodiment can assist in conveying the particles by their own gravity, avoiding the accumulation of particles in the ejection housing 2, and the inclined angle design can accurately match the operating range of the subsequent agitation assembly 5, allowing the agitation assembly 5 to fully cover the particles in the ejection housing 2 and ensuring that each batch of particles can be effectively acted upon. The fixed connection of the support table 3 with the granulator body 1 and the collection bin 4 can ensure the stability of the overall structure, avoiding the displacement of the collection bin 4 during the granulation process due to vibration, which affects the normal reception of the particles. The agitation assembly 5 is installed at the top of the ejection housing 2, which facilitates the maintenance and repair of the assembly and allows the agitation components to extend into the ejection housing 2 from top to bottom, forming a direct and uniform scattering effect on the high-temperature particles and laying a foundation for the subsequent cooling step.

[0029] The water cooling mechanism 6 is installed at the top of the support table 3, and the output end of the water cooling mechanism 6 is installed on both sides of the inner wall of the ejection housing 2.

[0030] It should be noted that the water cooling mechanism 6 described in this embodiment is installed at the top of the support table 3, which can form a close layout with the collection bin 4, facilitating the recycling of cooling water and reducing resource loss caused by the length of the pipeline. The output end of the water cooling mechanism 6 is symmetrically installed on both sides of the inner wall of the ejection housing 2, which allows the cooling water to act on the particles from both sides of the particle conveying path, forming a full-range cooling coverage and avoiding uneven cooling of the particles on one side. The arrangement of the output ends on both sides can cooperate with the state of the particles after being scattered by the agitation assembly 5, allowing the dispersed particles to more fully contact the cooling water, greatly improving the cooling efficiency and further reducing the possibility of particle adhesion.

[0031] Specifically, the high-temperature plastic particles generated by the granulator body 1 enter the inclined discharge housing 2 from the discharge port, the discharge housing 2 utilizes the gravity of the particles to assist the conveying by virtue of the inclined design of the discharge housing 2, and at the same time, the stirring assembly 5 installed at the top of the discharge housing 2 is started to directly and uniformly scatter the high-temperature particles in the housing, preventing the particles from gathering due to high temperature, and then the water cooling mechanism 6 installed at the top of the support table 3 starts to work, and the output end of the water cooling mechanism 6 sprays cooling water from both sides of the inner wall of the discharge housing 2 to the scattered particles, forming a full-range cooling coverage, so that the particles in the dispersed state can be more fully contacted with the cooling water, realizing rapid and uniform cooling, and the water cooling mechanism 6 is close to the collecting bin 4 on the support table 3, so that the cooling water can smoothly enter the collecting bin 4 after flowing through the particles for subsequent recycling, and finally the cooled and shaped particles slide into the collecting bin 4 along the inclined direction of the discharge housing 2 to complete the collection, and in the working process, the scattering effect of the stirring assembly 5 directly solves the problem that the high-temperature particles are easy to gather in the background art, and the design of the water cooling mechanism 6 spraying from both sides realizes uniform cooling of the scattered particles, and the two work together to completely avoid the adhesion and clumping of the particles due to gathering and uneven cooling, thereby solving the core problem raised in the background art and ensuring the forming quality of the plastic particles.

[0032] In an embodiment of the present application, as shown in Figures 1-4 The stirring assembly 5 includes a protective cover plate 51, a driving device 52, a driving arm 53 and a stirring head 54, wherein the protective cover plate 51 is clamped on the top of the discharge housing 2 by bolts, the driving device 52 is installed on the top of the protective cover plate 51, one end of the driving arm 53 is rotatably connected to the inner bottom of the discharge housing 2, the other end of the driving arm 53 penetrates the bottom of the protective cover plate 51 and is fixedly connected with the output end of the driving device 52, and the stirring head 54 is fixedly sleeved on one end of the driving arm 53, and the outer wall of the stirring head 54 is fixedly connected with a plurality of stirring plates 541.

[0033] It should be noted that the protective cover plate 51 described in the present embodiment adopts a bolt clamping mode, which not only ensures the sealing connection with the discharge housing 2 to prevent particles from splashing or foreign matter from entering, but also facilitates disassembly, and subsequent maintenance of the interior of the discharge housing 2 or the stirring assembly 5 is more convenient to operate, the two ends of the driving arm 53 are respectively connected to the inner bottom of the discharge housing 2 and the driving device 52, and this two-end supporting structure can improve the stability of the driving arm 53 during rotation, avoiding uneven scattering effect due to shaking caused by high-speed rotation, and the plurality of stirring plates 541 on the outer wall of the stirring head 54 can increase the contact area with the particles, so that the high-temperature gathered particles can be more fully divided, further improving the effect of scattering and preventing adhesion, and the driving device 52 is a driving motor.

[0034] Specifically, when the granulator body 1 discharges high-temperature particles into the discharge shell 2, the driving device 52 is started and drives the driving arm 53 to rotate, and the driving arm 53 synchronously drives the stirring head 54 and the stirring plate 541 of the outer wall to rotate in the discharge shell 2, and the stirring plate 541 directly acts on the gathered high-temperature particles to disperse them into a dispersed state, thereby fundamentally solving the sticking problem caused by the gathering of high-temperature particles in the background art, creating conditions for uniform cooling of the subsequent water cooling mechanism 6, and thereby avoiding the influence of particle caking on the molding quality.

[0035] In an embodiment of the present application, as shown in Figures 1-4 The water cooling mechanism 6 includes a filter plate 61, a water tank 62, a connecting head 63, and a spraying assembly 64, wherein the filter plate 61 is clamped to the inner wall of the collection bin 4, the water tank 62 is installed on the top of the support table 3 and located on one side of the collection bin 4, the connecting head 63 is arranged between the water tank 62 and the collection bin 4 and connected through the connecting head 63, and the spraying assembly 64 is installed on the top of the water tank 62, and the output ends of the spraying assembly 64 are symmetrically installed on the inner walls of the discharge shell 2.

[0036] It should be noted that the filter plate 61 described in the present embodiment is clamped to the inner wall of the collection bin 4, which not only can effectively separate the cooled particles from the cooling water, but also can replace filter plates 61 with different pore sizes according to the particle size to adapt to the production needs of particles of different specifications, the water tank 62 and the collection bin 4 are connected through the connecting head 63 to form a circulating loop of cooling water, without the need for continuous addition of new water, reducing water resource waste, and the output ends of the spraying assembly 64 are symmetrically installed on the inner walls of the discharge shell 2, which can ensure that the cooling water is sprayed from both sides of the particle conveying path at the same time, avoiding temperature differences caused by unilateral cooling, and improving cooling uniformity.

[0037] Specifically, after the particles are dispersed by the stirring assembly 5, the spraying assembly 64 sprays cooling water from both sides of the inner wall of the discharge shell 2 to the dispersed particles, realizing rapid cooling and setting of the particles, and the cooled particles and the cooling water slide together into the collection bin 4, the filter plate 61 intercepts the particles above, and the cooling water penetrates to the bottom of the collection bin 4 and then returns to the water tank 62 through the connecting head 63 for recycling, and in this process, the symmetrical spraying design of the spraying assembly 64 solves the problem of uneven cooling of particles in the background technology, and in combination with the dispersing effect of the stirring assembly 5, the sticking and caking of particles caused by high-temperature gathering and untimely cooling are completely avoided, and the water circulation design also improves the resource utilization rate.

[0038] In an embodiment of the present application, as shown in Figures 1-4As shown, the spraying assembly 64 comprises a pump body 641, an output pipe 642, a connecting pipe 643 and a spraying plate 644, wherein the pump body 641 is mounted on the top of the water tank 62, one end of the output pipe 642 is fixedly connected with the output end of the pump body 641, the spraying plate 644 is symmetrically fixedly connected on the inner wall of the discharge shell 2, the connecting pipe 643 is arranged between the spraying plate 644 and the other end of the output pipe 642 and connected through the connecting pipe 643.

[0039] It should be noted that the pump body 641 described in this embodiment provides stable pressure for the cooling water, ensuring that the cooling water can be sprayed out of the spraying plate 644 with appropriate force, which not only guarantees the cooling effect, but also avoids the situation that the particles are dispersed and deviated from the conveying path due to excessive pressure. The combined connection of the output pipe 642 and the connecting pipe 643 can flexibly adjust the pipeline layout according to the installation position of the discharge shell 2 and the water tank 62, thereby improving the adaptability of the overall structure. The spraying plate 644 is symmetrically fixed on the inner wall of the discharge shell 2, which can form a uniform spraying area for the cooling water in the shell, ensuring that each dispersed particle can be in contact with the cooling water.

[0040] Specifically, when the water cooling process is started, the pump body 641 extracts cooling water from the water tank 62 and pressurizes it. The pressurized cooling water is delivered to the connecting pipe 643 through the output pipe 642, and then distributed to the spraying plate 644 symmetrically installed on the inner wall of the discharge shell 2 through the connecting pipe 643. Finally, the cooling water is sprayed out of the spraying plate 644 to act on the dispersed particles. The stable pressure provided by the pump body 641 guarantees the coverage range and cooling efficiency of the cooling water. In combination with the symmetrical layout of the spraying plate 644, the problem of uneven cooling of the particles in the background art is solved. In cooperation with the agitating assembly 5, the particles are effectively prevented from being adhered and clumped due to high temperature, thereby ensuring the quality of the particle forming.

[0041] In an embodiment of the present application, as shown in Figures 1-4 The input end of the connecting head 63 is located below the filter plate 61, and the inner wall of the collection bin 4 is fixedly connected with a protrusion for supporting the filter plate 61.

[0042] It should be noted that the input end of the connecting head 63 described in this embodiment is located below the filter plate 61, which can ensure that the cooling water flowing back to the water tank 62 is clean water filtered by the filter plate 61, thereby preventing particles, debris or impurities from entering the water tank 62 with the cooling water, and further preventing the spraying assembly 64 from being clogged to affect the cooling effect. The protrusion on the inner wall of the collection bin 4 stably supports the filter plate 61, preventing the filter plate 61 from deforming or shifting due to the weight of the particles, and ensuring that the separation effect of the particles and the cooling water is always stable.

[0043] In an embodiment of the present application, as shown in Figures 1-4 A plurality of nozzles are installed on the spraying plate 644 at equal intervals, and the spraying angles of the nozzles are all inclined.

[0044] It should be noted that the plurality of nozzles on the spray plate 644 are installed at equal intervals in the embodiment, so that the cooling water forms a uniform spray density in the discharge housing 2, avoids the occurrence of a cooling blind area, ensures that each particle can contact the cooling water, the nozzles are inclined, so that the spray direction of the cooling water is adapted to the conveying direction of the particles in the discharge housing 2, so that the cooling water can more accurately act on the surface of the particles, improve the heat exchange efficiency, and at the same time avoid the waste caused by directly spraying the cooling water to the inner wall of the discharge housing 2.

[0045] In summary, in the plastic particle granulator, the high-temperature plastic particles generated by the granulator main body 1 enter the inclined discharge housing 2, the driving device 52 in the stirring assembly 5 drives the driving arm 53, the stirring head 54 and the stirring plate 541 to rotate, the high-temperature particles in the housing are dispersed to prevent aggregation, then the pump body 641 of the water cooling mechanism 6 extracts cooling water from the water tank 62 and pressurizes, is transported to the spray plate 644 on both sides of the inner wall of the discharge housing 2 through the output pipeline 642 and the connecting pipeline 643, and synchronously sprays cooling water to the dispersed particles through the inclined nozzles, realizes uniform cooling, and the cooled particles and the cooling water slide to the collecting bin 4 together, the filter plate 61 separates the particles and the cooling water, the cooling water is returned to the water tank 62 through the connecting head 63 for circulation, and the particles are left in the collecting bin 4 for collection. In the whole process, the dispersion effect of the stirring assembly 5 solves the problem that the high-temperature particles are easy to aggregate in the background art, the symmetrical spraying and inclined nozzle design of the water cooling mechanism 6 solve the problem of uneven cooling, and the two cooperate to completely avoid the adhesion and clumping of the particles due to aggregation and uneven cooling, and ensure the forming quality of the plastic particles.
