Description

Plastic granulator Technical Field The application relates to the field of plastic processing, in particular to a plastic granulator. Background The plastic granulator is a device for cutting plastic strips into small sections of particles and is usually positioned at the tail end of the plastic extruder. The material strips extruded by the plastic extruder are cooled and hardened by water cooling and then are conveyed into a plastic granulator for granulating. In the prior art, the granulating machine continuously rolls and shears granular or strip-shaped plastic by a hob, so that the aim of granulating is fulfilled, and the quality of the performance of the hob is one of key factors for ensuring whether the granulator produces normal slices or not. The blade of the existing granulator is divided into a blade and a cutter shaft, and the blade and the cutter shaft are integrally designed. When plastic grain cutting processes, the cutter blade and the die head work cooperatively, and the cutter blade and the die head work cooperatively in-process, the cutter blade is very easy to wear, in order to ensure the quality of products produced by the grain cutting machine, workers usually need to frequently detach, install, debug, replace and the like the cutter blade, and meanwhile, the workers are difficult to accurately control the time point of cutter changing, so that the problem that the cutter changing is too early or too late easily occurs, and the grain cutting quality of the grain cutting machine is seriously influenced. Disclosure of Invention The application provides a plastic granulator, which aims to solve the problem that the cutter changing of the granulator is too early or too late so as to seriously influence the granulating quality of the granulator. The application provides a plastic granulator, which adopts the following technical scheme: a plastic pelletizer, comprising: the device comprises a case, wherein one end of the case is a feeding end, the other end of the case is a discharging end, and the case is hollow; The utility model provides a grain cutting assembly, is located outside the quick-witted case, grain cutting assembly includes grain cutting motor, grain cutting knife rest, grain cutting fly cutter and grain cutting baffle, grain cutting motor is located grain cutting knife rest is last, grain cutting motor is flexible motor, grain cutting motor's telescopic shaft wears out grain cutting knife rest, grain cutting motor's telescopic shaft is kept away from grain cutting knife rest's one end is provided with the mounting box, grain cutting fly cutter detachable connection is in on the mounting box, grain cutting baffle is located grain cutting knife rest is kept away from the one end of discharge end, grain cutting baffle is used for blockking grain cutting plastics pops out the feed end, be provided with in the mounting box with grain cutting fly cutter pops out pop-up mechanism. Through adopting above-mentioned technical scheme, when will cut the processing to the plastic strip, at first pass through the feed end with the plastic strip, the grain subassembly that is located the feed end can carry out the grain processing to the plastic strip, set up into grain motor, grain knife rest, grain fly cutter and the combination of grain baffle with the grain subassembly, make at the in-process of plastic grain processing, the grain motor drives the grain fly cutter and cuts the plastic strip, the grain baffle has prevented the plastic pellet effectively and has popped out the feed end, simultaneously because grain fly cutter can dismantle and connect on the mounting box, make after having used a period, the staff be convenient for change the grain fly cutter of wearing and tearing, only need pop out the grain fly cutter through pop out the mechanism when changing can, the flow such as dismantle the blade in the prior art has been simplified to a certain extent, the installation, debugging, change, the setting of grain baffle, simultaneously because the setting of grain subassembly, make the staff can more accurate and convenient the operation that the grain cutter was traded to the grain cutter, the problem of grain cutter that the quality was influenced too early or too late to a certain extent has been solved. Optionally, receive the material subassembly, including receiving material spout, receipts material baffle and receipts workbin, receive the one end of material spout and be located the quick-witted incasement, receive the other end of material spout and be located outside the quick-witted case, receive the one end slope setting of material spout from the one end of quick-witted incasement to the one end outside the quick-witted case, it wears to establish to receive the material baffle in the material spout, it connects to receive the material baffle rotation receive on the inside wall of material spout, receive the workbin and be located outside the machine case.
