Description

Technical Field

[0001] The utility model relates to the technical field of extruder feeding, in particular to a feeding device for a plastic extruder. Background Art

[0002] In plastic extrusion equipment, plastic extruders are usually called main machines, while the subsequent equipment plastic extrusion molding machines are called auxiliary machines. After more than 100 years of development, plastic extruders have evolved from the original single screw to twin screws, multiple screws, and even screwless machines. Plastic extruders (main machines) can be matched with various plastic molding auxiliary machines such as pipes, films, holding materials, monofilaments, flat wires, strapping tapes, extruded nets, plates (sheets), profiles, granulation, cable coating, etc. to form various plastic extrusion molding production lines and produce various plastic products. Therefore, plastic extrusion molding machinery is one of the widely used machines in the plastic processing industry, whether now or in the future.

[0003] In the process of realizing the utility model, the inventors found that the following problems existed in the prior art and have not been solved: the existing feeding device for plastic extruder does not have a good adjustment function, because the stirring and anti-blocking mechanism of the device is mostly fixed above the feed hopper, and the added material is mostly poured by a bucket, the anti-blocking mechanism affects the convenience of the bucket pouring, and the granular material may be scattered if not careful, which is in urgent need of improvement. Therefore, we propose a feeding device for plastic extruder. Utility Model Content

[0006] The bottom of the feed hopper is connected to a material barrel, and a slot is provided on the upper surface of the feed hopper at a side away from the limiting rod;

[0007] A convex block is fixedly installed on the lower side of the front wall of the limit rod close to the horizontal plate, and a limit block is fixedly installed on the top of the limit rod;

Since the limit rod and the horizontal plate are movable and penetrated, they rotate around the limit rod to make the horizontal plate and the stirring rod located outside the feed hopper, and then the utensil is used to dump the plastic granular material. The adjustable design is convenient for dumping the granular material in the later stage.

Whenever a person holds the handle to adjust the horizontal plate, the pressure monitored by the pressure sensor is greater than the set threshold, the processor issues a command, the electromagnet is turned on, and the insertion rod is moved up, otherwise the electromagnet is turned off, thereby realizing the intelligent opening and closing of the electromagnet, and there is no need to open and close the electromagnet, thereby simplifying the operation process of each feeding.

[0012] As an optional solution of the technical solution of the present application, a battery is fixedly installed on one side of the gantry. The battery is electrically connected to the electromagnet through a wire. The battery can provide electrical energy to avoid pulling excessively long wires and reduce the cost required for power supply.

[0013] As an optional solution of the technical solution of the present application, sliders are fixedly installed on both sides of the iron block, the sliders are movably positioned in the slide rails, and the slide rails are fixed on the inner wall of the gantry. The cooperation between the sliders and the slide rails can be used to limit the position of the iron block, so that it can move vertically stably.

[0014] As an optional solution of the technical solution of the present application, ear plates are fixedly installed on the bottom of both sides of the barrel, and positioning holes are opened on both sides of the ear plates. Bolts can be passed through the positioning holes of the ear plates and screwed to the preset threaded grooves on the external extruder to limit the barrel stably and support later shifting, replacement and maintenance.

By setting a limit rod, an insertion rod and an electromagnet, when the feeding device for the plastic extruder is used, whenever material is added, the electromagnet can be turned on to temporarily absorb the positioning iron block, so that the insertion rod moves up and out of the slot, and then the cross plate is lifted upward. Since the limit rod and the cross plate are movably connected, the limit rod is rotated as the center, so that the cross plate and the stirring rod are located outside the feed hopper, and then the utensil is used to dump the plastic granular material. The adjustable design is convenient for dumping the granular material in the later stage.

[0025] In this technical solution, the limit rod 2, the insertion rod 62 and the electromagnet 51 and other components can be used in combination. During the use of the feeding device for the plastic extruder, whenever material is added, the electromagnet 51 can be turned on, and the electromagnet 51 temporarily absorbs the positioning iron block, so that the insertion rod 62 moves up and out of the slot, and then the cross plate 3 is lifted upward. Since the limit rod 2 and the cross plate 3 are movable and penetrated, they rotate around the limit rod 2, so that the cross plate 3 and the stirring rod 32 are located outside the feed hopper 1, and then the utensil is used to dump the plastic granular material.

[0030] By setting the limit rod 2, the insertion rod 62 and the electromagnet 51, during the use of the feeding device for the plastic extruder, whenever material is added, the electromagnet 51 can be turned on, and the electromagnet 51 temporarily absorbs the positioning iron block, so that the insertion rod 62 moves up and out of the slot, and then the cross plate 3 is lifted upward. Since the limit rod 2 and the cross plate 3 are movable and interpenetrating, they rotate around the limit rod 2 so that the cross plate 3 and the stirring rod 32 are located outside the feed hopper 1, and then the utensil is used to dump the plastic granular material. The adjustable design is convenient for the subsequent dumping of the granular material. By setting the pressure sensor 41 and the processor 33, whenever a person holds the handle 4 to adjust the cross plate 3, the pressure monitored by the pressure sensor 41 is greater than the set threshold value, and the processor 33 issues a command, the electromagnet 51 is turned on, and the insertion rod 62 moves up, otherwise the electromagnet 51 is closed, so that the intelligent opening and closing of the electromagnet 51 can be realized, and there is no need to open and close the electromagnet 51, thereby simplifying the operation process of each feeding.
