Technical Field

[0001] The utility model relates to the technical field of plastic extruders, in particular to a feeding device for a plastic extruder capable of preventing a feed port from being blocked. Background Art

[0002] The pipe production line consists of a control system, a plastic extruder, a die, a shaping cooling system, a tractor, a planetary cutting device and a turning rack. The plastic extruder is the core equipment of the pipe production line. Each pipe production line has two plastic extruders, one of which uses a strong conveying bushing and a high-efficiency screw to produce pipes, and the other plastic extruder is used to extrude marking lines. After the raw materials are put into the feeding device of the plastic extruder, due to the different densities and diameters of different raw materials, the materials with higher density and smaller diameter are more at the bottom of the feeding device, and the raw materials with lower density and larger diameter are more at the top of the feeding device, resulting in uneven distribution of the raw materials entering the casing, affecting product quality.

[0003] In view of the above problems, a Chinese patent with announcement number CN207535271U discloses a new type of plastic extruder, the technical key points of which are: including a casing, a support frame, a screw, a driving mechanism and a heating mechanism, the heating mechanism and the screw are both located in the casing, one end of the screw is connected to the output shaft of the driving mechanism, the driving mechanism and the casing are located on the support frame, the pitch of the middle part of the screw is smaller than the pitch of the two ends of the screw, a feeding port is provided at one end of the casing, a magnet adsorption layer is provided on the inner wall of the feeding port, an inclined isolation plate is also provided in the feeding port, the isolation plate divides the feeding port into two, one end of the isolation plate is fixedly connected to the inner wall of the feeding port and the feeding port and the isolation plate are funnel-shaped, a plurality of openings are provided on the isolation plate, and valves are provided on the plurality of openings, the user controls the opening and closing of different openings on the isolation plate according to needs, and evenly adds raw materials of different densities and diameters into the casing for processing, so as to avoid uneven addition of raw materials affecting the quality of the plastic pipe;

[0004] This solution solves the problem that raw materials of different densities and diameters cannot be uniformly added into the plastic extruder housing. However, the plastic extruder of the above solution may be blocked by materials when adding materials into the housing, which affects the normal use of the plastic extruder and further affects the quality of the pipe. Utility Model Content

[0005] In order to make up for the above shortcomings, the utility model provides a plastic extruder feeding device which can prevent the feed port from being blocked.

[0006] The utility model is achieved in this way:

[0008] The beneficial effect of adopting the above-mentioned further scheme is that the spiral blade is driven by a motor to rotate, so that the material falling on it is evenly brought out of the discharge pipe. At the same time, this discharge method can avoid the situation where the material blocks the discharge pipe. The use of the discharge hopper can reduce the amount of material falling into the discharge pipe, and at the same time can guide the material to fall above the spiral blade.

At this time, rotating the connecting shaft can make the pin slide into the horizontal groove. Because the angle of the connection between the vertical groove and the horizontal groove is an acute angle or a right angle, the rotating shaft and the connecting shaft can be snapped together, so that the user can maintain and replace the spiral blades in the future.

[0012] Furthermore, a sealing sleeve is installed at the bottom of the barrel cover, a sealing ring is installed on the outer side of the sealing sleeve, and the sealing sleeve is in contact with the inner wall of the storage barrel.

[0014] Furthermore, a feed port is provided on the top of the barrel cover, and a feed hopper is installed on the top of the feed port.

[0015] The beneficial effect of adopting the above further solution is that the feed hopper makes it convenient for the user to add materials into the storage barrel.

[0016] Furthermore, a half groove is provided on the outer side of the discharge pipe, and a baffle is slidably provided inside the half groove, a connecting block is installed on the outer side of the baffle, a fixing hole is provided on the top of the connecting block, and a hook is installed on the outer side of the storage barrel, and the fixing hole can be hung on the hook.

[0017] Furthermore, a metal ring is installed on the inner wall of the feed pipe, a magnet is installed on the bottom surface of the baffle, and the magnet and the metal ring are attracted to each other.

[0018] The beneficial effect of adopting the above-mentioned further scheme is that the baffle can block the opening of the discharge pipe, and the material cannot fall out of the discharge pipe. When the baffle is taken out of the half groove, the discharge pipe is in an open state, and the use of the hook and the fixing hole facilitates the user to place the baffle, and under the action of the magnet and the metal ring, the baffle can be fixed in the discharge pipe.

[0019] The beneficial effect of the utility model is that the utility model obtains a plastic extruder feeding device with anti-feed port blockage through the above design, which uses a motor to drive the spiral blade to rotate to evenly bring the material falling on it out of the discharge pipe. At the same time, this discharge method can avoid the situation where the material blocks the discharge pipe, and the use of the discharge hopper can reduce the amount of material falling into the discharge pipe, and at the same time can guide the material to fall above the spiral blade.
