Abstract
Description
Technical Field
[0001] This utility model relates to the field of extrusion equipment technology, and in particular to an extrusion device for producing insulating materials. Background Technology
[0002] Extruders can be classified into right-angle extruders and angled extruders based on the angle between the material flow direction at the die head and the screw centerline. Extruders rely on the pressure and shear force generated by the rotation of the screw to fully plasticize and uniformly mix the material, which is then shaped through a die. Plastic extruders can be broadly classified into twin-screw extruders, single-screw extruders, and less common multi-screw extruders and screwless extruders.
[0003] However, existing extruders commonly use hopper feeding or screw feeding methods when feeding materials. However, in these two methods, the screw feeding structure does not have the function of agitating the raw materials during the feeding process. Therefore, during the screw feeding process, the raw materials will generate agglomeration and blockage, which will affect the feeding efficiency of the raw materials and reduce the extrusion efficiency of the raw materials. Utility Model Content
[0004] To address the aforementioned problems, this invention proposes an extrusion apparatus for producing insulating materials to more accurately resolve these issues.
[0005] This utility model is achieved through the following technical solution:
[0006] This utility model proposes an extrusion device for producing insulating materials, including a barrel and a feeding assembly communicating with one side of the top of the barrel. The feeding assembly includes a hopper and a first motor disposed at the top of the hopper. The output end of the first motor passes through the top of the hopper and is connected to the feeding assembly. The feeding assembly includes a column connected to the output end of the first motor, a spiral feeder disposed at the bottom of the column, and a raw material scraper disposed on the circumference of the column and attached to the outer surface of the column. The raw material scraper is arranged in an arc from top to bottom. The inner side of the raw material scraper is connected to the column. The raw material scraper has several evenly distributed through holes.
[0007] Furthermore, in this invention, at least two raw material scrapers are provided.
[0008] Furthermore, the hopper includes an annular end for storing the screw feeder, and a storage end disposed on the upper end of the annular end and connected to the annular end via an inclined transition end. The inner wall of the storage end is in contact with a plurality of raw material scrapers.
[0009] Furthermore, in this invention, connecting plates are fixedly installed on both sides of the annular end, and a pneumatic vibrator is provided on the top of the connecting plate. The output end of the pneumatic vibrator contacts the outer surface of the inclined transition end through a contact end.
[0010] The surfaces come into contact.
[0011] Furthermore, the top of the hopper is provided with a raw material injection port, which is connected to an external injection device.
[0012] Furthermore, the present invention includes a screw assembly inside the barrel, a second motor connected to the screw assembly and used to drive the screw assembly on one side of the barrel, and a base for the second motor and the bottom of the screw assembly.
[0013] Furthermore, in this invention, an extrusion head is provided at the end of the barrel furthest from the second motor.
[0014] The beneficial effects of this utility model are:
[0015] The hopper is designed to store raw materials, while the first motor drives the column and screw feeder to rotate. The rotating screw feeder transports the raw materials from the hopper to the feed cylinder, where they are sheared. The rotating main body drives multiple scrapers to rotate synchronously. These scrapers scoop up the raw materials from the hopper and move them upwards along the scrapers. The materials then fall into the feed cylinder through through holes and scraper ends, repeating the process with another scraper. The coordinated movement of multiple scrapers allows for repeated upward and downward movement of the raw materials, effectively preventing accumulation and clumping. Attached Figure Description

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are considered to belong to this utility model.
[0022] The scope of protection of the utility model. Example
[0023] Referring to Figures 1-4, an extrusion device for producing insulating material includes a barrel 1 and a feeding assembly 2 connected to one side of the top of the barrel 1. The feeding assembly 2 includes a hopper 21 and a first motor 22 disposed on the top of the hopper 21. The output end of the first motor 22 passes through the top of the hopper 21 and is connected to a feeding assembly 3. The feeding assembly 3 includes a column 31 connected to the output end of the first motor 22, a spiral feeder 32 disposed at the bottom of the column 31, and a raw material scraper 33 disposed on the circumference of the column 31 and attached to the outer surface of the column 31. The raw material scraper 33 is arranged in an arc from top to bottom. The inner side of the raw material scraper 33 is connected to the column 31. The raw material scraper 33 has several evenly distributed through holes 34.
[0024] The hopper 21 is designed to store raw materials for use. The first motor 22 drives the column 31 and the screw feeder 32 to rotate. The rotating screw feeder 32 transports the raw materials in the hopper 21 to the material cylinder 1 for shearing. The rotating main body drives multiple material scrapers 33 to rotate synchronously. The rotating material scrapers 33 scoop up the raw materials in the hopper 21 and move them upward along the scrapers 33. The materials then fall into the material cylinder 1 through the through hole 34 and the end of the scraper 33, and repeat the process through another scraper 33. The cooperation of multiple scrapers 33 allows the raw materials to repeatedly move upward and fall, effectively preventing the accumulation and clumping of raw materials.
[0025] In this embodiment, at least two raw material scrapers 33 are provided.
[0026] In this embodiment, a raw material injection port 23 is provided on the top of the hopper 21. The raw material injection port 23 is connected to an external injection device. The setting of the raw material injection port 23 makes it convenient for workers to continuously inject raw materials into the hopper 21 through the external injection device, thereby ensuring the continuous conveying of raw materials.
[0027] As shown in the figure, the hopper 21 includes an annular end 211 for storing the screw feeder 32, and a storage end 213 disposed on the upper end of the annular end 211 and connected to the annular end 211 through an inclined transition end 212. The inner wall of the storage end 213 is in contact with several raw material scrapers 33.
[0028] The storage end 213 is designed to store a large amount of raw materials. The raw materials located below the storage end will fall through the inclined transition end 212 to the top of the storage end 213 and be conveyed into the material cylinder 1 by the screw feeder 32.
[0029] As shown in the figure, connecting plates 4 are fixedly installed on both sides of the annular end 211, and a pneumatic vibrator 41 is provided on the top of the connecting plate 4. The output end of the pneumatic vibrator 41 is connected to the outer surface of the inclined transition end 212 through the contact end 42.
[0030] The surfaces come into contact;
[0031] The pneumatic vibrator 41 can vibrate the material that has moved to the inclined transition end 212, and make the material move to the periphery of the top of the annular end 211 due to the vibration force. The material above the inclined transition end 212 will repeatedly rise and fall due to the movement of the material scraper 33. At the same time, after the material falls, the material in the inclined transition end 212 will be replenished first, and then the rising operation will be carried out.
[0032] As shown in the figure, a screw assembly is installed inside the barrel 1. A second motor 51 is installed on one side of the barrel 1, which is connected to the screw assembly and is used to drive the screw assembly. A base 5 is installed at the bottom of the second motor 51 and the screw assembly. An extrusion head 52 is installed at the end of the barrel 1 away from the second motor 51.
[0033] The second motor 51 can drive the screw assembly to rotate, and the rotating screw assembly will convey and shear the raw material output by the screw feeder 32, and output the processed raw material through the extrusion head 52.
[0034] In this embodiment, the principle of the extruder is a mature technology that is already known to those skilled in the art. Moreover, the extruder is not the subject to be protected in this application. Therefore, given that the structure and principle of the extruder itself are already known, it will not be described in detail in this application.
[0035] It should be noted that this utility model only protects the mechanical part, and the functions implemented by the software control part are not within the scope of protection of this utility model.
[0036] Of course, there may be other implementations of this utility model. Based on this implementation, other implementations obtained by those skilled in the art without any creative effort are all within the scope of protection of this utility model.
