Abstract
The utility model discloses a plastic extruder capable of effectively preventing materials from being heated or cooled non-uniformly. The plastic extruder comprises a charging barrel, wherein two ends of the charging barrel are respectively provided with a feed hopper and a discharge opening; and the drainage tube with a one-way valve is arranged on the wall on the outer side of the charging barrel, is led out from a position which is close to the discharge opening, and is connected with the feed hopper. The drainage tube with the one-way valve is arranged on the wall on the outer side of the barrel, so that materials in the charging barrel maintain appropriate temperature, thermal cycling is realized, the materials are mixed uniformly, manual barrel cleaning operation is reduced, and the production efficiency and the product quality are improved.
Description
Technical field
The utility model relates to a kind of plastic extruder with drainage tube.
Background technology
In the technique known field, 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 then is called subsidiary engine.Plastic extruder derives twin-screw, multiscrew by original single screw rod through 100 years of development, even does not have different types of machines such as screw rod.Plastic extruder can mate with various plastic shaping subsidiary engines such as tubing, film, handful material, monofilament, flat filament, strap, crowded net, sheet material, profile shapes, granulation, cable coatings, forms various plastic extruding forming production lines, produces various plastic products.Therefore, no matter now or in the future plastic extruding forming machinery all be one of machine of being used widely in the plastic processing industry.
In the process that existing plastic extruder is produced; Usually have owing to barrel near overheated all the other materials everywhere of barrel tear drop, the overheated problem of causing uneven in temperature that cause of the material of discharging position; Not only influence production efficiency; Need the cost manpower and materials to clear up barrel, more can influence the quality of product.
The utility model content
The technical problem that the utility model will solve is: provide a kind of and can effectively prevent the plastic extruder that material is uneven in temperature.
The utility model solves the technical scheme that its technical problem adopted: a kind of plastic extruder with drainage tube; Comprise barrel; Be respectively equipped with feed hopper and discharging opening at described barrel two ends; On the outermost barrel of described barrel, be provided with the drainage tube with check valve, described drainage tube is from drawing near the position of discharging opening and linking to each other with feed hopper.
The beneficial effect of the utility model the utility model is: the utility model is through being provided with the drainage tube with check valve on the outermost barrel of barrel; Make the material in the barrel can keep certain temperature; Cold cycling; Make that the mixing of material is more even, reduced the work of labor cleaning's barrel, improved production efficiency and product quality.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Fig. 1 is the structural representation of the utility model.
Among the figure: 1. barrel, 2. feed hopper, 3. discharging opening, 4. drainage tube.
The specific embodiment
Combine accompanying drawing that the utility model is done further detailed explanation now.These accompanying drawings are the sketch map of simplification, the basic structure of the utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
A kind of plastic extruder of the utility model as shown in Figure 1 with drainage tube; Comprise barrel 1; Be respectively equipped with feed hopper 2 and discharging opening 3 at described barrel 1 two ends; On the outermost barrel of described barrel 1, be provided with the drainage tube 4 with check valve, described drainage tube 4 is from drawing near the position of discharging opening 3 and linking to each other with feed hopper 2.
With above-mentioned desirable embodiment according to the utility model is enlightenment, and through above-mentioned description, the related work personnel can carry out various change and modification fully in the scope that does not depart from this utility model technological thought.The technical scope of this utility model is not limited to the content on the specification, must confirm its technical scope according to the claim scope.
