Description

Technical Field

[0001] This utility model relates to the field of extruder technology, and in particular to a high-efficiency material extrusion device for an extruder. Background Technology

[0002] Extruders are a type of plastic machinery. Based on the angle between the material flow direction at the die head and the screw centerline, extruder heads can be divided into right-angle die heads and angled die heads. Screw extruders rely on the pressure and shearing force generated by the rotation of the screw to fully plasticize and uniformly mix the material, which is then formed through a die. Plastic extruders can be basically classified into twin-screw extruders, single-screw extruders, and less common multi-screw extruders and screwless extruders.

[0003] The applicant discovered a Chinese patent, "A High-Efficiency Plasticizing Extruder," with publication (announcement) number "CN211542290U." This patent primarily utilizes a combination of a crushing roller, crushing protrusions, and a functional box for further crushing and preheating. After reheating through the feed pipe, the material enters the plasticizing extrusion cylinder, achieving the effect of crushing and preheating to facilitate plasticizing and melting. The screw rotation compresses and propels the material, and the high temperature transmitted by the heat transfer oil in the heating chamber plasticizes the material. The screw rotation then extrudes the material, thus solving the problem of slow plasticizing and heating of the material in the extruder, which prevents the screw speed from increasing and results in low extrusion efficiency. However, this patent and existing devices encounter damp and clump-like materials during operation. These materials, upon entering the extruder, slow down the melting process due to moisture and excessive size, causing them to adhere to the screw and accumulate, leading to machine malfunctions and unusability. Therefore, we propose a high-efficiency material extrusion device for extruders. Utility Model Content

[0004] The purpose of this invention is to provide an efficient material extrusion device for an extruder, in order to solve the problem mentioned in the background art that when working, the material is damp and clumped together. When these materials enter the extruder, the melting speed is slowed down due to the dampness, causing them to adhere to the screw and accumulate, resulting in machine failure and unusability.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency material extrusion device for an extruder, comprising an extruder, wherein a working component is provided inside the extruder, the working component comprising a first heating block and a screening plate, the first heating block being disposed inside the extrusion cylinder of the extruder, and a second heating block being disposed inside the extrusion cylinder of the extruder, wherein a local heat-conducting plate is disposed at the end of the first heating block away from the second heating block and at the left and right ends of the second heating block, wherein a heat dissipation rod is detachably connected to the front end of the local heat-conducting plate, the first heating block and the second heating block, a conveying pipe is disposed inside the extruder, and a driving component is disposed at the upper end of the extruder.

[0006] As a preferred embodiment, the extruder has two sets of through holes on one side, and the conveying pipe is inserted and connected to the through holes.

[0007] As a preferred embodiment, the screening plate has several sets of perforations, and the bottom end of the screening plate is stretched inward. The circumferential surface of the screening plate is fixedly installed inside the feed cylinder of the extruder. A brush is attached to the screening plate, and a wedge is fixedly installed at the upper end of the brush. An L-shaped connecting rod is fixedly installed at the upper end of the wedge. The end of the L-shaped connecting rod away from the wedge is fixedly installed on the feed cylinder of the extruder and located on a rotating rod inside the feed cylinder. A first fixing rod is fixedly installed on the rotating rod inside the feed cylinder, and the upper end of the first fixing rod is smooth from top to bottom and extends inward. A second fixing rod is fixedly installed at the lower end of the first fixing rod, and three sets of third fixing rods are arranged in a circular array on the circumferential surface of the second fixing rod.

[0008] As a preferred embodiment, the conveying pipe is interspersed with a first rotating shaft, and a first fixing plate is rotatably connected to the left end of the first rotating shaft. The end of the first fixing plate away from the first rotating shaft is fixedly installed with a screw, and a rotating groove is provided at the end of the first fixing plate that is rotatably connected to the first rotating shaft.

[0009] As a preferred embodiment, the driving component includes a linear reciprocating motor, a second rotating shaft is fixedly installed at the upper end of the rotating shaft of the linear reciprocating motor, a first connecting rod is inserted into the upper end of the second rotating shaft, a support block is provided at the lower end of the linear reciprocating motor, and one side of the support block is fixedly installed on one side of the extruder.

[0010] As a preferred embodiment, a connecting plate is fixedly installed on the upper end of the first connecting rod, and a second fixing plate is fixedly installed on the end of the connecting plate away from the first connecting rod.

The plug-in rod is detachably connected to the circumferential surface of the feeding pipe of the extruder.

[0011] The technical effects and advantages of this utility model are as follows:

[0012] 1. By setting the first heating block and the second heating block, the first temperature zone of the extrusion cylinder can be targeted for control and heating. This allows materials containing moisture to be preheated. Combined with local heat-conducting plates and heat dissipation plates, the service life of the first heating block, the second heating block, and the heating components in the extruder can be improved, and local overheating can be avoided. The perforated screening plate can pass through normal materials, while oversized materials and normal materials will be guided by the screening plate. The first fixed rod, the second fixed rod, and the third fixed rod form a multi-level dispersion structure. The third fixed rod stirs large materials. The combination of brush and wedge driven by the rotating rod can clean the screening plate in real time to prevent blockage and the presence of residual materials. The conveying pipe and the through hole are interlocked and combined with the first rotating shaft and the first fixed plate with the rotating groove to ensure that the parts on the conveying pipe can rotate without restriction. The conveying pipe can transport items such as coolant into the extrusion device to ensure the thermal balance of the extrusion device.

[0013] 2. A linear reciprocating motor provides stable power, with its shaft fixedly installed with the second rotating shaft. The first connecting rod enables efficient power transmission, driving the dust cover of the feed cylinder to move in tandem. The support block fixes the position of the motor, ensuring structural stability during operation and reducing the weight of the linear reciprocating motor support. The rigid connection between the connecting plate and the second fixed plate ensures that the power is evenly applied to the dust cover. Combined with the detachable connection between the plug rod and the feeding pipe, the sealing of the feeding channel is guaranteed. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see the appendix Figure 1 - Appendix Figure 5 An efficient material extrusion device for an extruder includes an extruder 1. The extruder 1 has a working component 2 inside, which includes a first heating block 207 and a screening plate 209. The first heating block 207 is disposed inside the extrusion cylinder of the extruder 1. A second heating block 208 is also disposed inside the extrusion cylinder of the extruder 1. Local heat-conducting plates 206 are disposed at the end of the first heating block 207 away from the second heating block 208 and at the left and right ends of the second heating block 208. A heat dissipation rod 203 is detachably connected to the front end of the local heat-conducting plate 206, the first heating block 207 and the second heating block 208. A conveying pipe 201 is disposed inside the extruder 1, and a driving component 3 is disposed at the upper end of the extruder 1.

[0023] The first heating block 207 and the second heating block 208 are parallel and both are located inside the extruder 1. The parts connected to the first heating block 207 and the second heating block 208 are in the same position and have the same specifications. The heat dissipation rod 203 is parallel to each other and is equipped with the first heating block 207, the second heating block 208 and the local heat-conducting plate 206, which concentrates the heat generated inside the parts onto the heat dissipation rod 203 to facilitate heat dissipation.

[0024] Two sets of through holes 202 are provided on one side of the extruder 1, and the conveying pipe 201 is inserted and connected to the through holes 202.

[0025] The parallel and identical through holes 202 on one side of the extruder 1 allow the conveying pipe 201 to pass through. If the conveying pipe 201 is located inside the extruder 1, it facilitates heat dissipation inside the extruder 1 and also makes it easy to clean the scale that has accumulated inside the conveying pipe 201 due to long-term use.

[0026] The screening plate 209 has several sets of perforations 210, and the bottom end of the screening plate 209 is stretched inward. The circumferential surface of the screening plate 209 is fixedly installed inside the feed cylinder of the extruder 1. The screening plate 209 is attached to a brush 214. A wedge block 213 is fixedly installed at the upper end of the brush 214. An L-shaped connecting rod 215 is fixedly installed at the upper end of the wedge block 213. The end of the L-shaped connecting rod 215 away from the wedge block 213 is fixedly installed on the feed cylinder of the extruder 1 and located on the rotating rod inside the feed cylinder. A first fixing rod 211 is fixedly installed on the rotating rod inside the feed cylinder. The upper end of the first fixing rod 211 is smooth from top to bottom. A second fixing rod 212 is fixedly installed at the lower end of the first fixing rod 211. The circumferential surface of the second fixing rod 212 has three sets of third fixing rods 217 arranged in a circular array.

[0027] The bottom edge of the screening plate 209 is stretched inward to form a slope, and several sets of the same size of leakage holes 210 are opened. The first fixing rod 211 has a smooth trend from top to bottom and is fixed on the rotating rod inside the feed cylinder of the extruder 1. The three sets of the same size third fixing rods 217 are arranged in a circular array and can break up the clumps of material.

[0028] The conveying pipe 201 is inserted and connected to the first rotating shaft 205. The left end of the first rotating shaft 205 is rotatably connected to the first fixing plate 204. The end of the first fixing plate 204 away from the first rotating shaft 205 is fixedly installed with the screw. The end of the first fixing plate 204 that is rotatably connected to the first rotating shaft 205 is provided with a rotating groove 216.

[0029] A rotating groove 216 is provided at one end of the first rotating shaft 205 that is rotatably connected to the first fixed plate 204. During use, the conveying pipe 201 can rotate within the rotating groove 216 without being restricted. The first fixed plate 204 is circular and can provide a connection function and the position for opening.

[0030] Specifically, the first heating block 207 and the second heating block 208 are installed parallel to each other inside the extrusion cylinder of the extruder 1. Local heat-conducting plates 206 are fixed to both ends of the second heating block 208 and the end of the first heating block 207 furthest from the second heating block 208. Parallel heat dissipation rods 203 are detachably connected to the local heat-conducting plates 206, the front ends of the first heating block 207 and the second heating block 208. The local heat-conducting plates 206 concentrate the heat from the internal parts of the first heating block 207 and the second heating block 208 onto the heat dissipation rods 203, achieving directional heat dissipation. The conveying pipe 201 passes through two sets of parallel through holes 202 on one side of the extruder 1, placing it inside the extrusion cylinder for easy cleaning of scale later. Inside the feed cylinder, a screening plate 209... The circumferential surface is fixed to the cylinder wall, and its bottom end is inclined inward to form a slope. The surface perforation 210 is used for material screening. The L-shaped connecting rod 215 drives the wedge block 213 and the brush 214 to rotate against the screening plate 209 to clean the material on the screening plate 209. The drive rod in the feed cylinder of the extruder 1 rotates, driving the first fixed rod 211, the second fixed rod 212 and the three sets of circular array of third fixed rods 217 to rotate. After the material is filtered by the screening plate 209, it passes through the third fixed rod 217. When the third fixed rod 217 rotates, it can break up the clumps of material. The first rotating shaft 205 rotates flexibly in the rotating groove 216 of the first fixed plate 204 to ensure that the conveying pipe 201 operates without obstruction. The whole system realizes efficient material extrusion and stable equipment operation.

[0031] Please see the appendix Figure 2 and attached Figure 6 The drive assembly 3 includes a linear reciprocating motor 306. A second rotating shaft 305 is fixedly installed on the upper end of the rotating shaft of the linear reciprocating motor 306. A first connecting rod 304 is inserted and connected to the upper end of the second rotating shaft 305. A support block 307 is provided at the lower end of the linear reciprocating motor 306. One side of the support block 307 is fixedly installed on one side of the extruder 1.

[0032] The lower end of the second rotating shaft 305 rotates on the shaft of the linear reciprocating motor 306, which facilitates the rotation of the second rotating shaft 305 and the parts on it, and then the first connecting rod 304 is convenient for connection.

[0033] A connecting plate 302 is fixedly installed on the upper end of the first connecting rod 304. A second fixing plate 301 is fixedly installed on the end of the connecting plate 302 away from the first connecting rod 304. The bottom end of the second fixing plate 301 is fixedly installed on the upper end of the dust cover of the feed cylinder. A plug-in rod 303 is fixedly installed on the upper end of the dust cover of the feed cylinder, and the interior of the plug-in rod 303 is detachably connected to the circumferential surface of the feeding pipe of the extruder 1.

[0034] The bottom end of the second fixing plate 301 is located on the upper end of the dust cover of the feed cylinder. Then, the plug rods 303 are parallel to each other and installed on the upper end of the dust cover. The feeding pipe is installed in the plug rods 303, so that it can be used together with the linear reciprocating motor 306 and its parts.

[0035] Specifically, when installing the drive component 3, first fix one side of the support block 307 to the side of the extruder 1, place the linear reciprocating motor 306 on the upper end of the support block 307, rotatably connect the lower end of the second rotating shaft 305 to the rotating shaft of the linear reciprocating motor 306, insert the first connecting rod 304 into its upper end, then fix the upper end of the first connecting rod 304 to the connecting plate 302, fix the other end of the connecting plate 302 to the second fixing plate 301, so that the bottom end of the second fixing plate 301 is fixed to the upper end of the dust cover of the feed cylinder, and at the same time, fix the parallel plug rod 303 on the upper end of the dust cover, and detachably connect the circumferential surface of the feeding pipe to the inside of the plug rod 303. During operation, the linear reciprocating motor 306 drives the rotating shaft to reciprocate, and drives the first connecting rod 304 to rotate through the second rotating shaft 305. The power is transmitted through the connecting plate 302 and the second fixing plate 301, and the plug rod 303 stabilizes the feeding pipe, realizes the linkage of the rotating rod in the feeding cylinder, and ensures smooth material conveying.

[0036] Working principle of this utility model: This utility model is a high-efficiency material extrusion device for an extruder. First, during operation, the material enters the feed cylinder through the feeding pipe. The plug rod 303 fixes the pipe. The linear reciprocating motor 306 drives the rotating shaft to reciprocate. Power is transmitted through the second rotating shaft 305, the first connecting rod 304, the connecting plate 302, and the second fixed plate 301, causing the dust cover on the feed cylinder to move up and down. Then, the second rotating shaft 305 rotates, which can rotate the parts on it to other positions. When the rotating shaft rotates, the first fixed rod 211, the second fixed rod 212, and the three sets of circular arrays of third fixed rods 217 rotate synchronously. The clumps of material are broken up and fall onto the screening plate 209. The inclined surface at the bottom of the plate guides the material to the drain hole 210. Material that meets the specifications also passes through the drain hole 210 and enters the extrusion cylinder. At the same time, the rotating rod drives the L-shaped connecting rod 215, the wedge block 213 and the brush 214 to rotate. The brush 214 adheres to the screening plate 209 to clean the residual material and prevent the drain hole 210 from being blocked. Inside the extrusion cylinder, the first heating block 207 and the second heating block 208 generate heat. The local heat-conducting plate 206 concentrates the heat to the parallel heat dissipation rod 203 to achieve directional heat dissipation. The conveying pipe 201 passes through the through hole 202 and is located inside the extrusion cylinder to assist in heat dissipation and facilitate the cleaning of scale.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
