Description

TECHNICAL FIELD

[0001] The application relates to the technical field of extruders, in particular to an extruder for plastic barrel production. BACKGROUND

[0002] The plastic extruder is a device widely used in the plastic processing industry and is mainly used for plastic forming. The main function of the plastic extruder is to make the material fully plasticize and uniformly mix through the pressure and shear force generated by the rotation of the screw, and then form various plastic products through the die.

[0003] In the related art, the plastic extruder can be used to produce a parison through a die, and then the parison is moved into a blow mold for inflation to support a hollow plastic product, such as a plastic barrel. In specific use, plastic particles need to be poured into the hopper of the plastic extruder, and the plastic particles are then heated and melted in the extruder housing for subsequent extrusion from the die.

[0004] However, since the extruder housing is in a high-temperature heating state when in operation, the hot gas generated after the plastic particles melt will be sprayed outward through the hopper, which not only easily causes the plastic particles to be sprayed outward, but also may cause high-temperature injury. Inventive content

[0005] Therefore, the application provides an extruder for plastic barrel production to solve the technical problem that the hopper of the plastic extruder is easily affected by the outward spraying of the hot gas in the related art.

[0010] A cover plate is buckled to the second end of the upper hopper;

[0011] A spiral agitator is arranged inside the upper hopper, an outer diameter of the spiral agitator is matched with an inner diameter of the second end of the upper hopper, and the spiral agitator is rotationally connected with the cover plate.

[0012] A driving motor is arranged on the cover plate, and a driving end of the driving motor is fixedly connected with the spiral agitator.

[0013] In some possible implementation manners, the first end side wall of the upper hopper is inwardly bent to form a bent plate, a liquid storage groove is formed between the bent plate and the side wall of the upper hopper, and the external thread is arranged on the side wall of the bent plate.

[0014] In some possible implementation manners, a glue distribution plate is transversely arranged at the second end port of the upper hopper, an arc-shaped strip-shaped notch is arranged at a position close to an edge of the glue distribution plate, the glue distribution plate is located below the cover plate, and a middle portion of the glue distribution plate is rotationally connected with the spiral agitator.

[0015] In some possible implementation manners, a top surface of the glue distribution plate is provided with a concave surface that is downwardly inclined to the arc-shaped strip-shaped notch.

[0016] In some possible implementation manners, a continuous chamfer surface is formed between the arc-shaped strip-shaped notch and the side wall of the upper hopper.

[0017] The plastic barrel production extruder provided by the embodiment of the application has at least the following beneficial effects:

[0018] In the plastic barrel production extruder provided by the embodiment of the application, the upper hopper is arranged at the lower hopper port of the extruder body in a threaded connection manner, an outer diameter of an upper end port of the upper hopper is smaller than that of a lower end port of the upper hopper.

DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments of the present application, all the other embodiments obtained by the person of ordinary skill in the art without creative labor fall within the protection scope of the present application.

[0029] As Figures 1-6 ​As shown, the plastic barrel production extruder provided by the embodiment of the application comprises an extruder body 100, a feeding hopper 200, a cover plate 500, a spiral agitator 600 and a driving motor 700, wherein the extruder body 100 is provided with a discharging hopper 110 at the top, the top end of the discharging hopper 110 is provided with a first opening 120, the outer surface of the sidewall of the discharging hopper 110 is provided with an internal thread 130, and the internal thread 130 is located at the top end of the feeding hopper 200. The plastic particles can be poured into the discharging hopper 110 through the first opening 120, and then the plastic particles are processed by the extruder body 100 for subsequent plastic barrel production work.

[0030] The extruder body 100 is connected with the feeding hopper 200 through the discharging hopper 110. Specifically, the feeding hopper 200 is in a funnel structure, and the outer diameter of the first end of the feeding hopper 200 is larger than that of the second end. The inner surface of the sidewall of the first end of the feeding hopper 200 is provided with an external thread 210, which is in a matched structure with the internal thread 130, so that the feeding hopper 200 can be connected with the discharging hopper 110 in a threaded connection mode. In addition, the inner surface of the sidewall of the feeding hopper 200 is coated with high-temperature glue 300, which can still maintain a sticky state in a high-temperature environment. The feeding hopper 200 is connected with a feeding pipe 400 in communication with the outer diameter on the side, and the plastic particles passing through the feeding pipe 400 can enter the inside of the extruder body 100 in sequence through the feeding hopper 200 and the discharging hopper 110.

[0031] In the embodiment, the second end of the feeding hopper 200 is provided with a cover plate 500 for closing the port. The inside of the feeding hopper 200 is also provided with a spiral agitator 600, which is rotationally connected with the cover plate 500, and the outer diameter of the spiral agitator 600 is matched with the inner diameter of the second end of the feeding hopper 200. This makes the spiral agitator 600 capable of closing the second end of the feeding hopper 200, so as to prevent the hot gas from carrying the plastic particles to blow outwards through the second end. In addition, the top end of the cover plate 500 is also provided with a driving motor 700 for driving the spiral agitator 600 to rotate.

[0032] In the extruder for plastic barrel production provided by the embodiment of the present application, the upper hopper 200 is mounted at the port of the lower hopper 110 of the extruder body 100 through threaded connection, the outer diameter of the upper end port of the upper hopper 200 is smaller than that of the lower end port. The inside of the upper hopper 200 is provided with a spiral agitator 600, the outer diameter of the spiral agitator 600 is matched with the outer diameter of the upper end port of the upper hopper 200. Moreover, the inner surface of the side wall of the upper hopper 200 is further provided with high-temperature glue 300 coated thereon. In actual use, the hot gas generated by the melting of plastic particles will blow the plastic particles in the lower hopper 110 to the upper hopper 200 and adhere to the high-temperature glue 300 on the inner surface thereof. Moreover, the spiral agitator 600 will also block the part of the plastic particles from moving upward, thereby effectively preventing the plastic particles and hot gas from splashing outward.

[0033] In some embodiments, the first end side wall of the upper hopper 200 is inwardly bent to form a bent plate 220, a liquid storage groove 230 is formed between the bent plate 220 and the side wall of the upper hopper 200, and the outer thread 210 of the upper hopper 200 is arranged on the wall surface of the bent plate 220. By arranging the liquid storage groove 230, the high-temperature glue 300 coated on the inner surface of the side wall of the upper hopper 200 can finally flow into the liquid storage groove 230, so as to facilitate subsequent use.

[0034] In some embodiments, the bottom end port of the upper hopper 200 is further provided with a glue distribution plate 800, which is located inside the upper hopper 200 and below the cover plate 500. The edge of the glue distribution plate 800 is provided with an arc-shaped strip-shaped gap 810, and the middle part of the glue distribution plate 800 is rotationally connected with the spiral agitator 600. Preferably, the upper surface of the glue distribution plate 800 is provided with a concave surface 820 inclined downward toward the arc-shaped strip-shaped gap 810. When the high-temperature glue 300 is poured onto the upper surface of the glue distribution plate 800, the high-temperature glue 300 will slide downward through the concave surface 820 and slide onto the inner surface of the side wall of the upper hopper 200 through the arc-shaped strip-shaped gap 810, and finally cover the entire inner surface.

[0035] Preferably, a continuous chamfer surface 900 is formed between the arc-shaped strip-shaped gap 810 and the inner surface of the side wall of the upper hopper 200, which enables the high-temperature glue 300 to flow smoothly and naturally to the inner surface of the side wall of the upper hopper 200 after passing through the arc-shaped strip-shaped gap 810.
