Description

Technical Field

[0001] The utility model relates to the technical field of plastic particle production, in particular to a plastic granulator with a particle anti-sticking function. Background Art

[0002] When producing plastic granules, the extruded strip plastic needs to be pelletized through a pelletizing device. In order to prevent the plastic granules from adhering to each other in the pelletizing device, the strip plastic needs to be cooled through a cooling device before pelletizing to obtain plastic granules of relatively uniform size.

[0003] For example, in the patent document with application number: 202122936449.7, a pelletizing device with an anti-sticking structure for a plastic extrusion granulator is disclosed, and it is specifically disclosed that by setting two scraper bars, the scraper bars can sweep off the particles at the top of the discharge port when flipping, thereby avoiding the accumulation of materials at the discharge port, thereby solving the problem of plastic particles sticking together due to a long time.

[0004] In the above technical scheme, after the strip plastic is cooled by the cooling device, the surface of the plastic particles is cooled and hardened, but the center position of the plastic particles and the output end of the cooling device cannot be in contact in time, resulting in the presence of unhardened plastic at the center position of the plastic particles when pelletizing. As a result, after pelletizing, the plastic particles contact each other, resulting in adhesion between the plastic particles. When the scraper sweeps the particles off, the adhesion between the plastic particles cannot be handled in time, affecting the quality of the plastic particles. At the same time, due to the heat generated during the cutting process, the cut surface of the plastic particles is very likely to generate heat that is difficult to dissipate, resulting in the problem of adhesion between the formed plastic particles. Utility Model Content

[0005] The technical problem solved by the utility model is to solve the adhesion problem caused by the accumulation of plastic particles after cutting in the prior art.

[0006] The utility model can be realized through the following technical scheme: a plastic granulator with a particle anti-sticking function, comprising a granulating mechanism, wherein the output end of the granulating mechanism is provided with a receiving substrate, the receiving substrate is inclined relative to a horizontal plane, and cooling water flows on the receiving substrate for cooling the plastic particles and guiding their movement.

[0007] A further technical improvement of the utility model is that guide outlets for allowing water to enter the water spray pipe and for allowing plastic particles to overflow are respectively arranged on both sides of the receiving substrate, and an end of the receiving substrate close to the water spray pipe is higher than an end of the receiving substrate close to the guide outlet.

[0008] A further technical improvement of the utility model is that bubble outlets are evenly provided at the bottom of the receiving substrate.

[0009] A further technical improvement of the utility model is that a scraping brush for scraping off plastic particles is slidably arranged on the receiving base plate.

[0010] The further technical improvement of the utility model is that: a screw rod assembly is arranged on the side of the receiving base plate, a scraper base is arranged on the output end of the screw rod assembly, and the scraper base is fixedly connected to the scraper brush.

[0011] A further technical improvement of the utility model is that a drying mechanism for drying the plastic particles is arranged at the output end of the guide outlet.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] 1. When the present application is used, the strip plastic is first pelletized by a pelletizing mechanism. At the same time, a receiving substrate is arranged at the output end of the pelletizing mechanism, so that the obtained plastic particles can fall onto the receiving substrate. Since the receiving substrate is inclined relative to the horizontal plane, the possibility of the plastic particles adhering to the receiving substrate can be reduced as much as possible. Moreover, since cooling water for cooling and guiding the plastic particles flows on the receiving substrate, the cut surface of the plastic particles can be quickly cooled by the running water. After cooling, the plastic particles are transferred due to the action of the running water, so as to avoid the problem of plastic particles sticking together due to the accumulation of plastic particles on the receiving substrate.

[0014] 2. The present application firstly arranges a bubble outlet so that the bubbles can continuously emerge to achieve the agitation effect of the flowing water, thereby further avoiding the accumulation of plastic particles. Also, by arranging a scraper brush that moves along the receiving substrate, the scraper brush is lifted up to clean the receiving substrate, thereby further avoiding the accumulation of plastic particles and reducing the possibility of adhesion of plastic particles.

[0022] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0023] See also Figure 1-5 As shown, a plastic granulator with a particle anti-sticking function includes a granulating mechanism 1, wherein the output end of the granulating mechanism 1 is provided with a cooling mechanism 2 for cooling the obtained plastic particles, and the output end of the cooling mechanism 2 is provided with a drying mechanism 3 for removing moisture from the plastic particles.

[0024] When in use, the pelletizing mechanism 1 is first used to pelletize the strip plastic, and the plastic particles obtained by pelletizing are transferred to the cooling mechanism 2 for cooling the plastic particles. Finally, the plastic particles are dried by the drying mechanism 3 to obtain finished plastic particles.

[0025] As a further embodiment of the present application, the pelletizing mechanism 1 is an existing device, and the cooling mechanism 2 includes a receiving substrate 21, wherein the receiving substrate 21 is tilted, and a water inlet pipe 22 is fixed to the side of the receiving substrate 21, wherein the output end of the water inlet pipe 22 is provided with a water spray pipe 23, and the receiving substrate 21 is located at the output end of the pelletizing mechanism 1, that is, when in use, the plastic pellets obtained by the pelletizing mechanism 1 fall on the receiving substrate 21, and then the water inlet pipe 22 is continuously used to supply water, and the cold water enters the receiving substrate through the water spray pipe 23. On the plate 21, the receiving substrate 21 is used to cool the fallen plastic particles. In this process, due to the presence of cooling water and the inclined setting of the receiving substrate 21, the plastic particles can be discharged after being cooled by the receiving substrate 21. A guide outlet 26 is provided at the end of the receiving substrate 21 away from the water inlet pipe 22, wherein the guide outlet 26 is located at the input end of the spin-drying mechanism 3. Therefore, in the present application, the end of the receiving substrate 21 close to the water inlet pipe 22 is higher than the end of the receiving substrate 21 close to the guide outlet 26.

[0026] Bubble outlets 27 are evenly arranged at the bottom of the receiving substrate 21 to realize the vibration of the accumulated plastic particles by the popped-up bubbles. When the plastic particles gather on the receiving substrate 21, the bubble outlets 27 are used to continuously push out the bubbles to realize the vibration of the plastic particles, which facilitates the separation of the plastic particles and avoids the adhesion of the plastic particles. At the same time, the cooperation of the water inlet pipe 22 and the water spray pipe 23 is used to further realize the anti-adhesion function of the plastic particles.

[0027] In order to prevent plastic particles from accumulating on the receiving substrate 21, the present application also provides a scraping mechanism for scraping off the plastic particles. The scraping mechanism includes a screw assembly 24 for providing power, a connecting slider 25 is provided at the output end of the screw assembly 24, and a side slide 28 is fixed on the connecting slider 25, wherein a side slide groove 29 is provided on the receiving substrate 21, wherein the side slide 28 and the side slide groove 29 are slidably connected, and a scraper base 210 is fixed between the side slides 28, and a scraper brush 211 is fixed on the scraper base 210, so that when in use, the start of the screw assembly 24 can drive the lateral movement of the connecting slider 25, and then drive the side slide 28 to move laterally, so that the scraper base 210 can move along the receiving substrate 21, so that the adhered plastic particles can be scraped off by the scraper brush 211, thereby preventing the plastic particles from adhering to the receiving substrate 21.

[0028] In the present application, the spin-drying mechanism 3 includes a spin-drying inner drum 31 and a spin-drying outer drum 35, and a spin-drying motor 33 is fixed inside the spin-drying outer drum 35, wherein the spin-drying inner drum 31 is installed at the output end of the spin-drying motor 33, and the spin-drying inner drum 31 is driven to rotate by starting the spin-drying motor 33, so that the plastic particles inside the spin-drying inner drum 31 can be dried. In the present application, the spin-drying inner drum 31 is located at the output end of the guide outlet 26, and the spin-drying inner drum 31 is used to receive the plastic particles. At the same time, the spin-drying inner drum 31 is evenly provided with spin-drying mesh holes, and a drain outlet is fixed at the bottom of the spin-drying outer drum 35 for discharging the obtained water, thereby realizing the function of drying the plastic particles.

[0029] Therefore, an inclined guide plate 34 is provided on the inner wall of the spin-drying inner drum 31 to guide and tilt the obtained plastic particles toward the inner wall of the spin-drying inner drum 31 to facilitate the unloading of the plastic particles. Therefore, a unloading component 32 for unloading the plastic particles is provided at the bottom of the spin-drying inner drum 31 and the bottom of the spin-drying outer drum 35.

[0030] In the present application, the unloading assembly 32 includes a unloading port 322, wherein the unloading port 322 is opened on the spin-drying outer drum 35, for realizing the unloading of plastic particles, and is arranged on the spin-drying inner drum 31 in cooperation with a unloading channel, wherein a rotating baffle 324 is rotatably arranged on the unloading channel, wherein the rotating baffle 324 and the side wall of the spin-drying inner drum 31 are fixed by magnetic attraction, for realizing the closing of the unloading channel, at this time, a push positioning block 325 is fixed on the rotating baffle 324, and a push positioning block 325 for cooperating with the push positioning block 325 is fixed on the side of the spin-drying outer drum 35 When in use, the push plate telescopic rod 321 contacts and pushes the positioning block 325. At this time, the electromagnetic force between the rotating baffle 324 and the spin-drying inner drum 31 disappears, that is, the rotating baffle 324 is rotated to a certain angle by the push plate telescopic rod 321. At this time, the plastic particles are discharged through the discharge port 322. In order to prevent the plastic particles from entering between the spin-drying inner drum 31 and the spin-drying outer drum 35, an outlet guide plate 323 is fixed on the side of the discharge port 322, wherein the outlet guide plate 323 is located between the spin-drying inner drum 31 and the spin-drying outer drum 35.

[0031] When the utility model is in use, firstly, the pelletizing function of the strip plastic is realized by the pelletizing mechanism 1, and the plastic particles obtained by the pelletizing are transferred to the cooling mechanism 2. At this time, the plastic particles obtained by the pelletizing mechanism 1 fall on the receiving substrate 21, and then the water inlet pipe 22 is used to continuously supply water, and the cold water enters the receiving substrate 21 through the water spray pipe 23, and the receiving substrate 21 is used to cool the fallen plastic particles, and finally the plastic particles enter the interior of the spin-drying inner drum 31, and the spin-drying motor 33 is used to drive the spin-drying inner drum 31 to rotate, so that the spin-drying inner drum 31 can be used to spin out excess water to between the spin-drying inner drum 31 and the spin-drying outer drum 35, and the spin-drying outer drum 35 is used to discharge water, and finally, by opening the unloading component 32, that is, using the push plate telescopic rod 321 to rotate the rotating baffle 324 to a certain angle, the plastic particles are unloaded through the unloading port 322 to obtain finished plastic particles.
