Description

Technical Field

[0001] The present application belongs to the technical field of extrusion granulation machines, and in particular relates to a waste self-collecting and self-cleaning device for an extrusion granulation machine. Background Art

[0002] An extrusion granulator is a granulation device that can granulate a certain material and shape it into a specified shape. It is mainly used in the pharmaceutical industry, chemical industry and food industry. Among them, in the chemical industry, the extrusion granulator is mainly used to granulate high molecular materials such as plastics and rubber and process them into required products. Its high production efficiency, low noise, long life and low energy consumption make it have a wide range of application prospects in the chemical industry. In the prior art, an extrusion granulator generally includes an extrusion device and a granulation device. The extrusion device is used to mix and plasticize the raw materials. The formed plastic melt is extruded from the die head of the extruder, sliced, and then granulated by the granulation device to form plastic particles. The extrusion device generally includes a main extruder and a second extruder. In the actual application process, the die head of the main extruder is set above the feed port of the second extruder, and the feed port of the second extruder is open. During the production process, in order to cool down the material entering the feed port of the second extruder, an air pipe is generally set on the side of the feed port of the second extruder away from the first extruder for blowing and cooling the material in the feed port of the second extruder. When the second extruder rotates and feeds the material in the feed port, material debris will be generated. At this time, under the action of the air pipe, some of the debris will be blown out of the feed port of the second extruder and accumulated below the feed port. At present, in order to deal with this phenomenon, the material accumulated below the feed port of the granulation device is generally cleaned manually. However, this method not only wastes a lot of manpower costs, but also makes manual cleaning very difficult due to the accumulation of various pipelines below the feed port. Therefore, a new extrusion granulator is urgently needed to solve the above problems. Utility Model Content

[0032] like Figure 1 As shown, in the prior art, the extrusion granulator includes a first extruder 1 and a second extruder 2, and the discharge end of the first extruder 1 is located above the feed port 2-1 of the second extruder 2. During the production process, the material discharged from the discharge end of the first extruder 1 enters the second extruder 2 through the feed port 2-1 for further processing. However, in actual application, since the feed port 2-1 is far away from the side of the first extruder 1 and an air pipe for blowing and cooling the material in the feed port 2-1 is provided, part of the material will be blown out of the feed port 2-1, and then accumulated under the feed port of the second extruder, making it difficult to clean. In this regard, the embodiment of the present application aims at this technical problem and provides a waste self-collection and self-cleaning device for an extrusion granulator, such as Figure 2As shown, the waste self-collecting and self-cleaning device is arranged below the feed inlet 2-1 of the second extruder 2 to collect the material (or waste) blown out from the feed inlet 2-1 of the second extruder 2, thereby effectively solving the technical problem that too much waste is easily accumulated below the feed inlet 2-1 of the second extruder 2 during the production process and it is difficult to clean up;

[0033] like Figure 3 As shown, the waste self-collecting and self-cleaning device includes a first side plate 3, a second side plate 4, a front plate 5, a rear plate 6 and a bottom plate 7 which are mutually surrounded to form a rectangular frame; two reserved wire holes 8 are provided on the first side plate 3 to facilitate the connection of the feed port 2-1 with the outside. In the actual application process, the technicians in this field can also set the reserved holes 8 on the second side plate 4 according to the actual wiring needs, and also set the reserved wire holes on the first side plate 3 and the second side plate 4 at the same time. When in use, the first side panel 3 and the second side panel 4 are respectively fixed on the mounting seat of the second extruder 2 so as to realize the connection between the waste self-collection and self-cleaning device and the second extruder 2. In this embodiment, the outer sides of the first side panel 3 and the second side panel 4 are respectively provided with a first clamping strip 9, and the mounting seat 2-2 of the second extruder 2 is provided with a first clamping groove (not shown in the figure) adapted thereto at a position corresponding to the first clamping strip 9. When installed, the first side panel 3 and the mounting seat 2-2 of the second extruder 2 and the second side panel 4 and the mounting seat 2-2 of the second extruder 2 are fixed together by the mutual clamping of the first clamping strip 9 and the first clamping groove. In actual application, the first side panel 3 and the second side panel 4 can also be fixedly connected to the second extruder 2 by the conventional connection method used in the prior art, such as welding, screw connection, bonding or other clamping methods that can achieve fixed connection. Figure 4 As shown, in order to facilitate the cleaning of the waste in the waste self-collecting and self-cleaning device, the bottom plate 7 is tilted downward along the direction from the rear plate 6 to the front plate 5 so that the waste entering the waste self-collecting and self-cleaning device can slide to the downwardly inclined end of the bottom plate 7 under the action of its own gravity. At the same time, a discharge port 10 is provided at the downwardly inclined end of the bottom plate 7 for discharging the collected waste. A detachable collecting trough 11 is connected to the bottom end of the bottom plate 7 and corresponds to the position below the discharge port 10 for collecting the waste discharged from the discharge port 10.

[0034] In actual application, a small amount of material may accumulate in the corners of the waste self-collection and self-cleaning device and cannot slide down to the discharge port 10 by its own gravity. Therefore, in some embodiments, the front panel 5 is set to be detachably connected with the first side panel 3 and the second side panel 4, for example, it can be connected by a conventional snap connection or buckle connection in the prior art. At the same time, the front panel 5 and the bottom panel 7 are set to be detachably connected or hinged. In this way, the front panel 5 can be disassembled or opened, and it is convenient to manually clean the waste accumulated in the corners of the waste self-collection and self-cleaning device to the discharge port 10 for discharge.

[0035] like Figure 5 As shown, in some embodiments, in order to facilitate the disassembly of the aggregate trough 11 for subsequent processing of the materials, the aggregate trough 11 and the base plate 7 are connected by a snap-fitting manner, specifically: second snap-fitting grooves 12 are respectively provided at the bottom of the base plate 7 and at positions corresponding to the opposite sides of the discharge port 10, and a second snap-fitting strip 13 adapted to the second snap-fitting groove 12 is provided at the top of the aggregate trough 11, and the aggregate trough 11 and the base plate 7 are detachably connected together by snapping the second snap-fitting strip 13 and the second snap-fitting groove 12 together.

[0036] During application, in order to facilitate the staff to observe the waste collected in the waste self-collecting and self-cleaning device, the first side panel 3, the second side panel 4, the front panel 5, the rear panel 6, the bottom panel 7 and the collecting trough 11 are all made of transparent materials.

[0037] Recombination Figure 3It can be seen that in some embodiments, in order to further improve the collection effect of the waste self-collection and self-cleaning device, the waste self-collection and self-cleaning device also includes an introduction mechanism, and the introduction mechanism includes a guide plate 14, and the guide plate 14 is fixed to the top of the rear plate 6 and the first side plate 3 and the second side plate 4, and is used to introduce the waste into the waste self-collection and self-cleaning device. In the actual application process, the guide plate 14 can also be fixed separately to the top of the rear plate 6, and the technicians in this field can determine it according to actual needs. The introduction mechanism also includes a flexible introduction member 15, and the flexible introduction member 15 is a flexible plastic film or a flexible plastic sheet. One end of the flexible introduction member 15 is detachably connected to the guide plate 14, and the other end is detachably connected to the bottom of the discharge end of the first extruder 1 so that the waste flying out of the discharge end of the first extruder 1 can enter the waste self-collection and self-cleaning device through the introduction mechanism. At the same time, in order to facilitate the disassembly and assembly of the flexible guide member 15, the flexible guide member 15 and the guide plate 14 as well as the discharge end of the first extruder 1 are connected by buckling. Specifically, the flexible guide member 15 is provided with a plurality of connecting holes 16 at the opposite ends thereof, and the guide plate 14 and the discharge end of the first extruder 1 are provided with connecting buckles 17 matched with the connecting holes 16. The flexible guide member 15 and the guide plate 14 as well as the discharge end of the first extruder 1 are connected by connecting buckles 17 and connecting holes 16.
