Water cooling machine barrel with internal circulation cooling function

Technical Field

The utility model relates to a plastics are extruded and are equipped, concretely relates to inside circulative cooling's water-cooling barrel.

Background

Extruders are one of the class of plastic machines, originating from the 18 th century. The extruder can divide the machine head into a right-angle machine head, an oblique-angle machine head and the like according to the material flow direction of the machine head and the included angle of the central line of the screw. The screw extruder depends on the pressure and the shearing force generated by the rotation of the screw, so that materials can be fully plasticized and uniformly mixed and are molded through a neck mold. Plastics extruders can be largely classified into twin-screw extruders, single-screw extruders and, less frequently, multi-screw extruders and also screwless extruders. The machine head and the mouth mold are usually integrated, and are commonly called the machine head; however, there are cases where the head and the die are separated from each other. The machine head is used for converting plastic melt in rotary motion into parallel linear motion, so that the plastic is further plasticized uniformly, the melt is uniformly and stably led into the die, and necessary forming pressure is given, so that the plastic is easy to form and the obtained product is compact. The mouth mold is a channel with a certain cross-sectional shape, and the plastic melt can obtain the required shape when flowing in the mouth mold and can be cooled and hardened by a shaping device and a cooling system outside the mouth mold to be molded. The components of the machine head and the mouth mold comprise a filter screen, a porous plate, a flow divider (sometimes the flow divider and the mold core are combined into a component), a mold core, the mouth mold, a machine neck and the like.

The invention provides a single-screw extrusion device with a cylinder water cooling system, which is named as a single-screw extrusion device with a cylinder water cooling system in China published patent No. CN208392611U, published 2019, 1 month and 18 days, and comprises a device body; the device body comprises hopper, extrusion storehouse, motor and water-cooling section of thick bamboo, the motor is located the extrusion storehouse outside, the motor front end sets up the shaft coupling, shaft coupling one end is provided with the pivot, the pivot is passed inside the shell stretches into the extrusion storehouse, the shell is located the extrusion storehouse outside, the inside hot plate that is provided with of shell, extrusion storehouse front end is provided with extrudees the mouth, it is provided with a water-cooling section of thick bamboo to extrude the mouth front end, the inside circulating pipe that has surrounded of water-cooling section of thick bamboo, circulating pipe one end leads to pipe to be connected with the circulating pump, the circulating pump passes through the water pipe and is connected with the water tank, the water tank leads to pipe and is connected with the circulating pipe. The utility model discloses a can carry out the continuous heating to extrusion storehouse inside through the hot plate during the use for the inside material in extrusion storehouse does not receive the influence of a water-cooling section of thick bamboo, guarantees the extrusion quality.

But has the disadvantages that the barrel part is still in the traditional single circulation mode, the cooling effect is good near the end of the extruder, and the cooling effect at the end is poor.

SUMMERY OF THE UTILITY MODEL

The utility model discloses a mostly be single circulation mode near extruder end cooling effect good and the poor problem of the cooling effect at terminal to current water-cooling barrel has designed an inside circulative cooling's water-cooling barrel.

A water-cooling machine barrel with internal circulation cooling is divided into an interface section and a cooling section;

a spiral groove is formed in the cooling section, and the section of the spiral groove is U-shaped;

the middle section of the cooling section is provided with a pipe section support seat for preventing the pipe section from deviating and bending;

and a cooling water pipe is arranged in the spiral groove.

When using the utility model discloses a water-cooling barrel, at first need with in the condenser tube winding advances the helicla flute, then link to each other interface section and extruder tip interface.

The spiral groove of U-shaped design makes condenser tube can laminate the inner wall more and increase condenser tube and water-cooling barrel contact surface simultaneously.

Preferably, the spiral groove is divided into a plurality of sections, 4 sections of spiral grooves are arranged between the pipe section support seat and the interface section, and 2 sections of spiral grooves are arranged between the pipe section support seat and the cooling section end point; all the spiral grooves are in the same direction.

Each section of spiral groove is respectively connected with a cooling water pipe and a corresponding water cooling system, so that the cooling effect of the whole section of the water cooling machine barrel can be uniform.

Preferably, the diameter of the circular arc surface of the section of the spiral groove is smaller than or equal to the thickness of the pipe wall of the cooling section of the water cooling machine barrel; the depth of the vertical surface is smaller than the diameter of the circular arc surface.

Preferably, the middle part of the pipe section support seat is provided with a long waist type window, and the window is sealed by high-temperature glass. The long waist type window can observe the specific state of the product in the water cooling machine barrel.

The beneficial effects of the utility model reside in that: the cooling effect is excellent, and the production process can be met; and a reciprocating circulation cooling liquid supply structure is adopted, so that the temperature of the roller surface is consistent, the cooling effect is good and uniform, and the machine can be stably produced.
