[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0029] See also Figure 1-Figure 6 .

[0030] In view of the problems mentioned in the above background technology, the embodiment of the utility model provides a new extruder to solve the above technical problems, and its technical solution is as follows:

[0031] A novel extruder includes an extruder body 100, wherein the extruder body 100 is fixed on a frame 110;

[0032] A feed bin 200 is provided on the feed hole of the extruder body 100; the feed bin 200 includes a conical bin 210 and a discharge barrel 220 connected up and down;

[0033] A stirring and scraping member is provided in the feed bin 200, and a motor 400 is provided on the top of the feed bin 200;

[0034] The stirring and scraping member includes: a stirring shaft 231, a stirring rod 1 241, a stirring rod 242, a stirring rod 3 243, an inclined plate 251 and a vertical scraper 252;

[0035] The stirring shaft 231 is vertically arranged in the conical bin 210 and the lower end of the stirring shaft 231 does not extend into the lower barrel 220;

[0036] The lower end of the stirring shaft 231 is designed not to extend into the discharge barrel 220 because the space in the discharge barrel 220 is small. If the lower end of the stirring shaft 231 extends into the discharge barrel 220, it will occupy the material discharge space and reduce the material discharge speed.

[0037] The upper end of the stirring shaft 231 is fixedly connected to the main shaft of the motor 400; the motor 400 can drive the stirring shaft 231 to rotate;

[0038] The stirring rod 1 241, the stirring rod 242, and the stirring rod 3 243 are fixed on the stirring shaft 231 in order from top to bottom;

[0039] The inclined plate 251 is fixed to the free ends of the stirring rod 1 241, the stirring rod 242, and the stirring rod 3 243, and the lengths of the stirring rod 1 241, the stirring rod 242, and the stirring rod 3 243 are successively reduced to make the inclined plate 251 in an inclined state; the inclination angle of the inclined plate 251 is adapted to the wall of the conical bin 210;

[0040] The vertical scraper 252 is fixedly connected to the lower end of the oblique plate 251 , and the vertical scraper 252 is located in the lower barrel 220 .

[0041] The inclined plate 251 is not only used to stir the material in the conical bin 210, but also to scrape the material adhered to the inner wall of the conical bin 210. At the same time, the main function of the inclined plate 251 in this patent is to serve as a supporting structure for the vertical scraper 252 and to connect the vertical scraper 252.

[0042] A novel extruder working method provided by the embodiment of the utility model is as follows:

[0043] 1. When the extruder is working, the motor 400 drives the stirring shaft 231 to rotate, driving the stirring rod 1 241, the stirring rod 242, the stirring rod 3 243, and the inclined plate 251 to rotate to stir the materials, thereby increasing the material discharge speed in the conical bin 210;

[0044] 2. When the oblique plate 251 rotates, it will drive the vertical scraper 252 to rotate synchronously. The vertical scraper 252 rotates close to the wall of the discharge barrel 220, scraping the material adhering to the wall of the barrel from the wall of the barrel and falling into the feed hole of the extruder; at the same time, the vertical scraper 252 rotates along the wall of the barrel, which can also increase the discharge speed of the material in the discharge barrel 220.

[0045] It should be noted that if some materials have strong adhesion after being deformed by heat, and the vertical scraper 252 is not easy to scrape off by rotating against the wall of the discharge barrel 220, the machine can be stopped, and the materials adhering to the wall of the barrel can be cooled and solidified, and the motor 400 can be turned on to drive the vertical scraper 252 to rotate. During the rotation process, the vertical scraper 252 can directly enter the solidified materials and scrape them off by rigid collision.

[0046] In this embodiment, the stirring rod 1 241, the stirring rod 242, and the stirring rod 3 243 each include four groups, and the four groups of stirring rod 1 241, stirring rod 242, and stirring rod 3 243 are arranged in a circular array; the free end of each group of stirring rod 1 241, stirring rod 242, and stirring rod 3 243 is fixed with an inclined plate 251.

[0047] In this embodiment, the annular plate 260 is fixedly connected between the four vertical scrapers 252 ; the annular plate 260 is fixedly connected between the four vertical scrapers 252 to improve the structural strength of the vertical scrapers 252 .

[0048] In this embodiment, the rear side of the inclined plate 251 is low connected to the wall of the conical bin 210, and the rear side of the vertical scraper 252 is low connected to the tube wall of the discharge barrel 220; wherein, the directional word "rear side" is relative to the stirring shaft 231, the side facing the stirring shaft 231 is the front side, and the side facing away from the stirring shaft 231 is the rear side.

[0049] In this embodiment, the stirring shaft 231 , the stirring rod 1 241 , the stirring rod 242 , the stirring rod 3 243 , the inclined plate 251 and the vertical scraper 252 are all made of stainless steel.

[0050] In this embodiment, a cooling component 300 is provided on the outer peripheral wall of the discharge barrel 220, and the cooling component 300 includes a cooling tube spirally wound on the outer peripheral wall of the discharge barrel 220, and a coolant flows in the cooling tube, and the coolant can also be cooling water; wherein, the liquid inlet and the liquid outlet of the cooling tube are connected to a container filled with coolant through a pump.

[0051] It should be noted that, as mentioned earlier, for materials with high adhesion, it is necessary to wait for the machine to be shut down and then perform the scraping operation after the materials have cooled and solidified. Here, a cooling component 300 is provided on the outer peripheral wall of the lower barrel 220. When the extruder is working, the coolant in the cooling pipe cools the lower barrel 220 to prevent the material from being deformed by heat in the lower barrel 220 and adhering to the wall of the lower barrel 220. In combination with the vertical scraper 252, the material can be prevented from sticking to the wall of the lower barrel.

[0052] A novel extruder provided by an embodiment of the utility model has the following beneficial effects: the utility model can avoid the situation where materials stick to the wall of the discharge barrel through the coordinated design of various structures, thereby increasing the discharge speed and ensuring the quality of the next batch of products.

[0053] The device embodiments described above are merely illustrative, wherein the units described as separate components may or may not be physically separated, and the components shown as units may or may not be physical units, and may be located in one place or distributed over multiple network units. Some or all of the modules may be selected according to actual needs to achieve the purpose of the solution of this embodiment.

[0054] In the present utility model, unless otherwise clearly stipulated and limited, the terms such as "installation", "setting", "connection", "fixation" and "screw-on" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integrated connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. Unless otherwise clearly defined, ordinary technicians in this field can understand the specific meanings of the above terms in the utility model according to the specific circumstances.

[0055] It is understandable that those skilled in the art can make equivalent substitutions or changes based on the technical solution and concept of the utility model, and all these changes or substitutions should fall within the protection scope of the claims attached to the utility model.
