Abstract
The invention relates to a threaded rod cooling system of a plastic extruder. The threaded rod cooling system comprises a hollow threaded rod. The top end of the threaded rod is closed. A pipe is arranged in the threaded rod and is a threaded pipe. The pipe is connected with an end cover which is provided with a liquid inlet and a liquid outlet. A connection piece is arranged between the end cover and the threaded rod. An insertion pipe on the connection piece is inserted into the tail portion of the threaded rod. The tail portion of the threaded rod is fixedly connected with a transmission gear. A seal ring is arranged on the insertion pipe on the connection piece and the tail portion of the threaded rod. The pipe is the threaded pipe, and cooling water enters the threaded rod from the threaded pipe and returns along the pipe and a hole in the center of the threaded rod; due to the fact that the pipe is the threaded pipe, cooling liquid is disturbed in the backflow process, and therefore turbulent flow is generated, the thermal coefficient is increased, and a better cooling effect is achieved.
Description
Technical field
The present invention relates to the field of cooling of mechanical part, particularly relate to a kind of cooled screw system of plastic extruder.
Background technology
In plastic extruding forming equipment, plastic extruder is referred to as main frame usually, and the follow-up equipment plastic extruding forming machine supporting with it is then called subsidiary engine.Plastic extruder, through the development of more than 100 years, derives twin-screw, multiscrew, even without different types of machines such as screw rods by original singe screw.Plastic extruder can with tubing, film, handful material, monofilament, flat filament, strap, squeeze the various plastic shaping subsidiary engines such as net, sheet material, profile shapes, granulation, cable be coated and mate, form various plastic extruding forming production line, produce various plastic products.Therefore, no matter now or in the future plastic extruding forming machinery, be all one of machine of being used widely in plastic processing industry.In plastic extruding forming equipment, heating is the necessary condition that plastic extrusion process can be carried out with cooling.Wherein heater is used for molten plastic, makes it to heat up, and reaches the requirement of technological operation.And during cooling device, ensure that the temperature range that plastics are in technological requirement sets.Be the waste heat that the shearing friction rotated to get rid of screw rod produces specifically, to avoid, temperature is too high makes plastics, incipient scorch or sizing difficulty.Wherein, cooled screw mainly adopts central water-cooling, and object increases material solid conveying ratio, stablizes gel quantity, improve the quality of products simultaneously.
In cooled screw structure under prior art condition, the turbulivity of flow of cooling water is little, thus causes thermal conductivity factor low, and the consumption of cooling water is large.
Summary of the invention
The present invention is in order to overcome deficiency of the prior art, provide a kind of cooled screw system of plastic extruder, the defect that when screw rod that instant invention overcomes plastic extruder takes central water-cooling, cooling water turbulivity is less, improves thermal conductivity factor, strengthens cooling effect.
The present invention is achieved through the following technical solutions:
A kind of cooled screw system of plastic extruder, comprise screw rod, described inside screw hollow, the top closure of screw rod, is provided with pipe in described screw rod, and described pipe is screwed pipe, described pipe is connected with end cap, end cap is provided with inlet, liquid outlet, is provided with connector between described end cap and screw rod, the Inserting Tube on described connector is inserted in the afterbody of screw rod.
The afterbody of described screw rod is fixedly connected with travelling gear.
Inserting Tube on described connector and screw rod tail are provided with sealing ring.
Compared with prior art, the invention has the beneficial effects as follows: the pipe in the present invention is screwed pipe, cooling water enters in screw rod from screwed pipe, return along in the hole of pipe and pitch, because pipe is screwed pipe, be disturbed during cooling fluid backflow, thus turbulization, increase large hot coefficient, reach better cooling effect.

In figure: 1, liquid outlet; 2, inlet; 3, end cap; 4, connector; 5, travelling gear; 6, runner; 7, pipe; 8, screw rod; 9, sealing ring; 10, Inserting Tube.
Detailed description of the invention
In order to make object of the present invention, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
As shown in Figure 1, the cooled screw system of described a kind of plastic extruder, comprises screw rod 8, screw rod 8 inner hollow, the top closure of screw rod 8, being provided with the pipe 7 for importing cooling water, forming the runner 6 that Cooling Water refluxes between the outer wall of pipe 7 and the inwall of screw rod 8 in described screw rod 8.Described pipe 7 is screwed pipe.One end of pipe 7 is connected with end cap 3, end cap 3 is provided with inlet 2, liquid outlet 1.Be provided with connector 4 between described end cap 3 and screw rod 8, be fixedly connected with between end cap 3 with connector 4, connector 4 comprises an Inserting Tube 10, and the Inserting Tube 10 on connector 4 is inserted in the afterbody of screw rod 8.Cooling fluid flows into screw rod 8 from the inlet 2 end cap 3 along pipe 7 inner, then flow out from the other end of pipe 7, return along the runner 6 between pipe 7 and screw rod 8, the heat on screw rod 8 is absorbed in return course, reduce the temperature of screw rod 8, return end cap 3 from connector 4 again, finally flow out from the liquid outlet 1 end cap 3, complete the cooling procedure to screw rod 8.
The afterbody of described screw rod 8 is fixedly connected with travelling gear 5, and travelling gear 5 is connected with the transmission system of plastic extruder, and under power drive, screw rod 8 rotates, and pushes the plastics under plastic raw materials and hot melt state.
Inserting Tube 10 on described connector 4 is provided with sealing ring 9 with screw rod 8 afterbody, and sealing ring 9 plays the effect preventing cooling water from spilling from the gap between Inserting Tube 10 and screw rod 8.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any amendments done within the spirit and principles in the present invention, equivalent replacement and improvement etc., all should be included within protection scope of the present invention.
