Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the invention; therefore, the invention is not limited to the specific embodiments disclosed below.

[0027] Please see Figures 1 to 3The utility model provides a cooling system for plastic particle production is set between screw extruder and cutting machine, including water storage pool 100, water scraping mechanism 200, water throwing mechanism 300 and drying mechanism 400.

[0028] Specifically, water storage pool 100 is used to store coolant and is arranged close to the side of screw extruder, and the plastic strip 1 extruded from the screw extruder can pass through the coolant in the water storage pool 100. Water scraping mechanism 200 is arranged close to the water storage pool 100, and the plastic strip 1 output from the water storage pool 100 can pass through the water scraping mechanism 200, and the water scraping mechanism 200 can preliminarily scrape off the coolant on the plastic strip 1.

[0029] Water throwing mechanism 300 is arranged close to the water scraping mechanism 200, and the plastic strip 1 output from the water scraping mechanism 200 can pass through the water throwing mechanism 300, and the water throwing mechanism 300 can pat the plastic strip 1 to throw off the coolant on the plastic strip 1. Drying mechanism 400 is arranged between the water throwing mechanism 300 and the cutting machine, and the plastic strip 1 can pass through the drying mechanism 400 and then enter the cutting machine, and the drying mechanism 400 is used to dry the plastic strip 1.

[0030] It should be noted that in the present application, the screw extruder is a commonly used screw extruder for plastic particle production in the prior art. The cutting machine is also a commonly used cutting machine for plastic particle production in the prior art.

[0031] In use, the plastic strip 1 extruded from the screw extruder sequentially passes through the water storage pool 100, the water scraping mechanism 200, the water throwing mechanism 300 and the drying mechanism 400 and then enters the cutting machine, the coolant in the water storage pool 100 cools the plastic strip 1, the water scraping mechanism 200 preliminarily scrapes off the coolant on the plastic strip 1, and the water throwing mechanism 300 throws off the coolant on the plastic strip 1 by patting the plastic strip 1. Then, the drying mechanism 400 dries the plastic strip 1, so that the plastic strip 1 finally entering the cutting machine is cooled and dried, thereby preventing the cutting machine from attaching to the related parts of the cutting machine during cutting, thereby preventing the cutting effect of the cutting machine from being affected.

[0032] In the embodiment, the water scraping mechanism 200 includes a first water collecting groove 210 and a plurality of water scraping rods 220, the first water collecting groove 210 is connected between the water storage pool 100 and the drying mechanism 400, and the plurality of water scraping rods 220 are arranged along the length direction of the first water collecting groove 210. After the plastic strip 1 comes out of the water storage pool, it can be sequentially and slidably connected to the water scraping rods 220. When the plastic strip 1 sequentially passes through the water scraping rods 220, the water scraping rods 220 hang off the coolant attached to the plastic strip 1, and the coolant falls into the first water collecting groove 210. In specific implementation, the water scraping rods 220 can be cylindrical to reduce damage to the plastic strip 1.

[0033] In the embodiment, the water throwing mechanism 300 comprises a second water receiving groove 310, a rotating power source 320, a rotating shaft 330, a mounting shaft 340 and a water throwing rod 350. The rotating shaft 330 is rotatably mounted on the second water receiving groove 310 and located at the side close to the drying mechanism 400. The rotating power source 320 is used to drive the rotating shaft 330 to rotate. It is to be noted that in the specific implementation, the rotating power source 320 can be all the mechanisms commonly used in the prior art which can drive the rotating shaft 330 to rotate.

[0034] The mounting shaft 340 has two ends, and the two mounting shafts 340 are fixedly sleeved on the two ends of the rotating shaft 330. The water throwing rod 350 has a plurality of water throwing rods 350 which are arranged in a circumferential direction and are spaced apart on the mounting shaft 340. The plastic strip 1 conveyed from the water scraping rod 220 is overlapped on the water throwing rod 350. When the rotating shaft 330 rotates, the water throwing rod 350 can sequentially hit the plastic strip 1.

[0035] Through the way of hitting, the cooling liquid attached to the plastic strip 1 can be thrown out, thereby achieving the purpose of removing the cooling liquid.

The water absorbing pad 500 can absorb the water on the plastic strip 1. In the specific implementation, the water absorbing pad 500 can be selected as water absorbing foam, water absorbing cotton and the like.

[0038] As a more preferred embodiment, in the specific implementation, the water absorbing pad 500 can be rotatably arranged on the outer cover 420. The movement of the plastic strip 1 is facilitated. At the same time, a plurality of limiting grooves can be formed in the water absorbing pad 500. The width of the limiting groove is equal to the diameter of the plastic, which can play a guiding role and can improve the contact area between the water absorbing pad 500 and the plastic strip 1, thereby improving the water absorbing effect.

[0039] The above-mentioned cooling system for plastic particle production is adopted:

[0040] In use, the high-temperature plastic strip 1 extruded from the screw extruder passes sequentially through the water storage tank 100, the scraper mechanism 200, the water-spraying mechanism 300, and the drying mechanism 400 before entering the cutter. The coolant in the water storage tank 100 cools the plastic strip 1, the scraper mechanism 200 initially scrapes off the coolant on the plastic strip 1, and the water-spraying mechanism 300 beats the plastic strip 1 to remove the coolant.

[0041] After being reabsorbed by the absorbent pad 500, the drying mechanism 400 dries and cools the plastic strip 1 again, so that the plastic strip 1 that finally enters the cutting machine is cooled and dry. This prevents the plastic strip from adhering to the relevant parts of the pelletizer during the cutting process, thus affecting the cutting effect of the cutting machine.
