Description
One, technical field
The utility model relates to a kind of mechanical production devices, specifically a kind of vertical cut formula underwater pelletizer that is used for plastics recovery.
Two, background technology
Along with science and technology development, the production and processing of high polymer is progressively deepened, and output and performance are all progressively improving.Pelleter is last procedure of high polymer polymerization process, and the performance of pelleter height directly has influence on the quality and the yield rate of product, as cools off untimelyly, for the crystallization high polymer, can increase degree of crystallinity, reduces transparency; In the production process of continuous large-scale, can not realize that as cutting knife sharpness is not enough from grinding, will pelletizing inhomogeneous, directly have influence on conveying, the reprocessing of product.Some developed countries have worked out many plastics recovery machineries for many years, but most of based on plastics in solid-state pelletizing, majority all adopts dry type tie rod formula or wet type strand pelletizer (being said underwater pelletizer) in the domestic enterprise, the shortcoming of this pelleter is: 1, hypocrystalline or noncrystalline high polymer existing equipment are adopted the liquid-ring type pelletizing, the easy conglomeration of macromolecular material that viscosity is higher, influence product quality, can cause when serious shutting down; 2, for reducing temperature, slitter shaft is big apart from cantilever, the pelletizing instability, and make troubles to operation; 3, production capacity is little, and power consumption is big, apparatus is huge, has not satisfied the demand in market.
Three, summary of the invention
The purpose of this utility model provides a kind of simple in structure, easy to operate vertical cut formula underwater pelletizer, and the core technology of this vertical cut formula underwater pelletizer is pelletizing in 40 degree warm water, and pelletizing evenly, stable performance, dismounting, cleaning be convenient.
The purpose of this utility model is achieved through the following technical solutions:
A kind of vertical cut formula underwater pelletizer, it is characterized in that: it comprises motor, power transmission shaft, flexible chuck, die head, hydraulic package, chilled water unit and frame, motor is fixed on the frame; Power transmission shaft is installed on the pedestal, and an end of power transmission shaft is connected with motor, and the other end is connected with flexible chuck; Flexible chuck matches with the end face of die head, and the hydraulic package that makes flexible chuck be pressed on die face equably is arranged in the pedestal; Under the effect of hydraulic system, flexible chuck moves to die head, and one group of blade on the promotion cutterhead sleeve is pressed on the end face of die head equably; Processing grain cooled off with the chilled water unit that solidifies be connected with pedestal.Flexible chuck, die head are worked in chilled water unit; Blade in the pelletizing, can reach self-grinding action again on the special ink-jet alloy end face of die head, make blade keep sharp.
Pressure is uniform and stable during for the work of assurance the utility model, pelletizing is even, and described flexible chuck comprises knife rest, blade, cutterhead sleeve, ball float, top board and lower platen, and one group of blade is arranged on the end face that on the knife rest and evenly is pressed on die head; The cutterhead sleeve set is on power transmission shaft, and knife rest is installed in an end of cutterhead sleeve, and ball float is arranged between the end and cutterhead sleeve of power transmission shaft; The other end of cutterhead sleeve connects with top board and lower platen on being fixed on power transmission shaft.Under the hydraulic package effect, blade is pressed on die face with identical pressure.
Power transmission shaft is connected with motor by shaft coupling in the utility model.On power transmission shaft, be provided with velometer and Pressure gauge.
Blade when preventing work on the knife rest flies out, and is provided with turnover cutter head cover on pedestal, and this cutter head can cover blade when covering on pelleter work, can raise during the tool changing sheet.For convenient of the present utility model moving, be provided with roller in the bottom of frame and prevent the brake block that roller slides.
Polymer melt is extruded from the plate of Cast Strip in the utility model, discharges the water cure globulate section that is cooled after the cutting knife scraping rotated at a high speed by melt threeway automatic valve.And the polymer melt of old equipment is sent into the pelleter pelletizing behind the cooling curing water spray cooling bath after the casting plate is extruded, and cuts into slices to cylindrical.Compared with prior art, the utility model has the advantages that: 1, even, the stable performance of pelletizing; 2, the automaticity height, easy to operate, noise is lower; 3, the first tie rod that the has changed legacy equipment operation of pelletizing has again been saved equipment, has improved efficient.
After the utility model appeared on the market, alternative old product was to satisfy the demand in market.It is applicable to various thermoplasticity objects, and as PEF, polypropylene, polyester and polyamide, its polymer melt can be used the screw extruder feed, also can use the gear pump feed.Pelletizing face is immersed in the high pressure chilled water flow, and the crystallization high polymer is cooled off rapidly, and the crystallization control degree guarantees transparency of products and glossiness as requested.It adopts flexible chuck and autogenous grinding knife structure, makes pelletizing even, and cutting knife prolongs about three times service life.This plant area area is little simultaneously, and energy consumption is low, and cost performance is higher than traditional granulate equipment.By using desirable web plate rheology and cutting knife geometry principle, by diffusing temperature technique, and adopt advanced isolated material and water flow measurement device, effectively avoid discharging to freeze.The utility model starting process full automation, scrappage is low; " discharging is curled " phenomenon can not take place; Upkeep cost is very low; The cutting knife of rotation can guarantee the lasting cleaning on web plate surface; Cutting knife is regulated automation, the automation of cutting knife abrasive disc; Change cutting knife and only need a few minutes.
