Abstract
The utility model discloses a screw type plastic extruder which comprises a material barrel. A screw rod is installed in the material barrel, a scraper is arranged at the upper side of the screw, a discharging head is arranged on the upper side of the scraper, a first discharging hole is arranged in the discharging head, a second discharging hole is arranged on the upper side of the first discharging hole, a third discharging hole is arranged at the upper side of the second discharging hole, a hollow cavity is formed between the first discharging hole and the second discharging hole, the screw type plastic extruder is provided with a transmission box oil pump, and a heating device is arranged on the outer side of the material barrel. The screw type plastic extruder enables a plastic product to be sufficiently homogenized in the extruder and meets the requirements of current plastic production for the development tendency of high speed, large length-diameter ratio and large torsion.
Description
Technical field
The utility model relates to a kind of plastic processing machinery equipment, relates in particular to a kind of screw plastic extruder.
Background technology
The screw plastic extruder is high-quality, efficient plastic extrusion facility, and this plastic extrusion machine equipment complete machine structure is reasonable in design, firm in structure durable, not fragile.Machine material bar adopts the heat treated carbon metallization processes, and hardness is not easy to wear by force, and be three times of general material-passing rod service life, adopts advanced lubricated type, weares and teares little, and large watt of seat thoroughly protected bearing, and operating maintenance is convenient.The screw plastic extruder more and more obtains market approval current, and application is also further extensive.In the prior art, the screw plastic extruder is widely used in the batcher of plastic granulating, painted, mixing, plastic sheeting, plastic material, tubing production and plastic injection equipment.But, because screw rod is single, make plastic product can not get therein sufficient homogenize, can not satisfy the trend of current plastics-production high speed, big L/D ratio, high pulling torque future development.Therefore, the defects based on plastic extruder in the prior art exists is necessary to make improvements.
The utility model content
The utility model provides a kind of screw plastic extruder, and the abundant homogenize of plastic product production satisfies the trend of current plastics-production high speed, big L/D ratio, high pulling torque development.
The utility model is to solve the problems of the technologies described above the technical scheme that adopts to provide a kind of screw plastic extruder, comprise barrel, screw rod is installed in the described barrel, described screw rod upside arranges scraper, the upside of described scraper sets out stub bar, offer discharge opening one in the described discharge head, the upside of described discharge opening one is offered discharge opening two, the upside of described discharge opening two is offered discharge opening three, form cavity between described discharge opening one and the discharge opening two, wherein, described screw plastic extruder assembling transmission case oil pump, described barrel arranged outside heater.
Above-mentioned screw plastic extruder wherein, is installed between described scraper and the discharge opening one and is protected the material net.
Above-mentioned screw plastic extruder, wherein, described discharge head arranged outside housing.
Above-mentioned screw plastic extruder wherein, is installed hopper on the described barrel.
Above-mentioned screw plastic extruder, wherein, described heater adopts the heat conduction fuel tank.
The utility model contrast prior art has following beneficial effect: the screw plastic extruder that the utility model provides, by assembling the transmission case oil pump at the screw plastic extruder, but the start and stop of robot brain device, realize the production automation, by offering discharge opening, the moisture that plastics can be produced in heating process and low molecule excreta discharge, guaranteed the quality of finished product, by at barrel arranged outside heater, temperature constant in guaranteeing to produce, reduce thermal loss, realize energy-conservation.
Description of drawings
The structural representation of the screw plastic extruder that Fig. 1 provides for the utility model.
The specific embodiment
The utility model will be further described below in conjunction with drawings and Examples.
The structural representation of the screw plastic extruder that Fig. 1 provides for the utility model.Among the figure, barrel 1, screw rod 2, scraper 3, cavity 5, discharge opening 1, discharge head 7, discharge opening 38, discharge opening 29, protect material net 10, transmission case fuel tank 11, hopper 12, heater 13.
See also above-mentioned accompanying drawing, the screw plastic extruder, comprise barrel 1, described barrel 1 interior installation screw rod 2, described screw rod 2 upsides arrange scraper 3, the upside of described scraper 3 sets out stub bar 7, offers discharge opening 1 in the described discharge head 7, and the upside of described discharge opening 1 is offered discharge opening 29, the upside of described discharge opening 29 is offered discharge opening 38, form cavity 5 between described discharge opening 1 and the discharge opening 29, wherein, described screw plastic extruder assembling transmission case oil pump 11, described barrel 1 arranged outside heater 13, in equipment operation, by at screw plastic extruder assembling transmission case oil pump 11, but the start and stop of robot brain device, realize the production automation, by offering discharge opening, the moisture that plastics can be produced in heating process and low molecule excreta discharge, and have guaranteed the quality of finished product.By at barrel 1 arranged outside heater, guarantee temperature constant in the production, reduce thermal loss, realize energy-conservation.
Install between described scraper 3 and the discharge opening 1 and protect material net 10, described material net 10 intensity of protecting are high, and resistance to overturning is good, has good anticorrosive and decorative effect.Described discharge head 7 arranged outside housings 4 can best protection discharge head 7.Hopper 12 is installed on the described barrel 1, has been made things convenient for charging.Described heater 13 adopts the heat conduction fuel tank, and temperature constant in fully guaranteeing to produce reduces thermal loss, realizes energy-conserving and environment-protective.
Although the utility model discloses as above with preferred embodiment; so it is not to limit the present invention, any those skilled in the art, without departing from the spirit and scope of the present invention; when can doing a little modification and perfect, so protection scope of the present invention is when with being as the criterion that claims were defined.
